Bore the dowel holes where the lines cross. Send an email directly to our store by filling in the form below. Frames made with dowelled butt joints are surprisingly strong. Correctly use the safety protection and control devices on the equipment, shall not be arbitrarily dismantled. When working, controlling the punching head to press the die can reduce the stamping noise. The most commonly used aperture is the aperture used for the extraction of M3 buds (aperture ID 2.60. .secure-payment .container { The length direction is the same, but the width direction is different from the width of a die. Regularly check the synchronization of the upper and lower turntables, and adjust if necessary. (6) The mold adjustment method is shown in the following figure. Since Wiedemann invented R2 manual multi-station punch in 1932, numerical control turret punch (NCT) has been widely used in the field of sheet metal processing and has been developing in structure and performance. 3.CNC turret punch driven by servo motor, Estimated machining time for CNC turret punch, Maintenance and repair of CNC turret presses, Problems that should be noted in the use of CNC turret punch press, CNC turret punching machine operation specification, Mechanical main drive turret punch (mechanical series), Maintenance and repair of hydraulic systems (hydraulic series), Die clearance for mild steel, stainless steel, aluminum, copper and brass, 36 Types of Thermomechanical TreatmentProcess, Top 10 Shearing Machine Manufacturers in China (2022 Updated), Global Top 10 Press Brake Manufacturers (2022 Updated), Top 20 Laser Cutting Machine Manufacturers in 2022, Pump Control Technology: ItBrings Performance Upgrade to Hydraulic Press Brake, 13 Types of Springs: Performance And Application. In terms of the development situation of the sheet metal industry, there should be a lot of room for development. 3) At present, the X-axis stroke is 1250mm, 1500mm, 2000mm, 2500mm. Waste bounce refers to the phenomenon of punching waste not smoothly discharged from the hole in the die, but bounced to the end of the die or the surface of the part blank, this ejected waste is also known as pad slag. If, after a period of operation of the machine, there is a chronic shortage of air pressure and the above methods are not effective, the following two options may be considered: Raise the lower limit of the air compressor, or lower the critical value of the air alarm, by turning a small steel screw in the direction of - on the lower part of the pressure gauge, at this time you can see the green needle follows the corresponding movement.

Finally glue the dowels in place to ensure perfect results every time. After the jaws are released, the jaws move outwards, and move in the X-axis in the positive direction of Amm, and then move inwards to the corresponding position, clamping, thus completing the entire movement of the jaws. How to Optimize Spherical Head Forming Process? 1Error in the size of the machined hole to the reference edge of x and y positioning. To develop, on the basis of the process analysis, all process information required for processing e.g. The tool used for NCT punching must be thicker than the material. NCT stamping is the movement of the workpiece back and forth on the tool turret, so in general, there can be no bumps on the reverse side of the workpiece, except for small bumps of insignificant size and low height. In addition, the machine tool has a compact structure and occupies a small floor area. The power supply is put into position, well-grounded (three power lines, one grounding line, wire diameter10mm2or more), the voltage range is required to 380+10%-5%, if the voltage is unstable, add a regulator power supply; if there is leakage protection, add an isolation transformer, the total power above 50KVA. Put the T-axis back to the reference point. Place the machine in manual mode and press the adjustment button first to adjust the punch to the upper dead point. Process analysis according to the requirements of the drawings of the parts, including the analysis of the structural processability of the parts, rational analysis of the material and design accuracy, approximate process steps, etc. The other causes mentioned above, such as unstable air pressure, can be addressed on a case-by-case basis. Universal and quick dowelling jig for corner, T-butt and edge-to-edge connections. The table below shows the recommended die clearances for a range of materials and thicknesses. Drill both holes. As shown in the picture on the left below: If, after the workpiece has been discharged from the NCT, other secondary processing is required to produce the shape, then an anti-still angle method can be used.

Rolling cutter composed of two parts which include the die seat and roller wheel group. For the user, increasing the service life of the tool can significantly reduce the cost of use. The machine is strictly manned and absolutely not allowed to be operated by uncertified personnel. Reliable oil filtration can improve the service life of the hydraulic system, our oil quality should be controlled within the NAS1638 class 6-8, beyond the above range it is recommended to replace the filter element or filtration to replace hydraulic oil. Heaters - Electric, Gas, Paraffin, Diesel, Plumbing Tools, Drain Cleaners and Equipment, Designed for drilling 6,8 &10mm dowel holes. The two or more salad holes are filled together with a width of 10mm and length depending on the actual situation. For example, the lower die for 2mm plate cannot be processed for 3mm plate, nor for 1mm plate, otherwise it will increase the wear and even break the die. The number of turret press diescan be divided into 20, 24, 32, 40, etc. After a couple of trial holes I was able to knock up the base of a unit in no time at all. (2) The positioning pin of the turntable is connected to the pin by two cylinders through the coupling plate, the cylinder is supported on the fixed seat, the pin is controlled by two five-way solenoid valve, the speed is adjusted by a one-way throttle valve when positioning. In NCT processing, it is common to punch a large rectangular hole. Machine Mart 2022, All rights reserved.

When this happens, you should use the regular professional CNC mold manufacturer to manufacture the mold and use the calibration bar to correct the machines mold position. Use this glue gun for hot-gluing a variety of materials from wood to metal. The origin pin is located to the left of the feed table and is used to determine the reference point of the X-axis. (5) When high Cr die material and high Cr stamping plate (such as 1Cr13 and other stainless steel) continuous punching, the temperature will rise and produce affinity. Rotation time of approximately 2.5 seconds for tool change. } It is recommended to use medium-soft 46-grain grinding wheel. The forming process must be used at low speed, preferably with a delay time. Whether the stamped plates are well lubricated. 2) Precautions for the selection of molds. The minimum distance from the edge of the NCT perforation is 3T and the minimum distance between two perforations is 6T. Also, wipe down the area around the die before putting it into the die. .secure-payment .we-accept span.panel { Set includes an aluminium jig with pre aligned holes, clamps and depth stops. To drill subsequent holes, drop one drill-bit guide over a short dowel rod pushed into the last hole drilled. The role of the hydraulic station is to provide a constant source of oil pressure to the punch. If misplaced, it can break the mold and even damage the machine. (3) Set the correct value of the restricted area according to the different types of machines. Leave the stile or leg of a corner joint overlong until the joint is finished. If the edge is greater than 15mm, no filler is used. Shut off the oil pump, turn off the main power of the machine, The communication cable must be plugged in when the machine tools computer power failure, Let down the machine guard, close the movable table, put away the tools. height: 42px; This kind of machine tool is driven by hydraulic cylinder and controlled by electro-hydraulic servo valve. The biggest advantage of this structure is that the inertia of the feed is small and can be driven by a servomotor with low torque. Note: New oil and clean oil are two completely different concepts and should not be confused. After a single punch, if the stopping position of the punch exceeds the upper dead point, after proving that the braking signal has been issued, the single punch will brake the cam pads and move the corresponding angle in a clockwise direction. A thorough understanding of the technical requirements of the drawings, such as dimensional accuracy, shape and position tolerances, surface roughness, the material of the workpiece, hardness, machinability and number of parts. If for some reason the home pin does not fall or lift during operation, neither the X nor Y-axis can be moved and can only be restarted after the home pin has fallen. The upper and lower cavities of the cylinder make the piston rod drive the ram up and down in reciprocal motion, impacting the mold for punching. What Are The Criteria? Hi, I'm Shanefounder of MachineMfg. The solution is to change the position of the jaws, change the tool position, change the size of the mold or design a substitute jaw. The LASER is slower than the NCT perforation, with the fastest LASER flight cutting speeds of around 100 ppm compared to over 400 ppm for the NCT. In terms of ownership, there are more than 20000 sets of CNC presses in the United States and nearly 20000 sets in Japan. The amount of die sharpening is a certain amount, the normal amount is 4mm, if this value is reached the punch will be scrapped, if continued use, it will easily cause damage to the die and machine. The guide key on the machine turret is intact. The workshop has a dedicated person to program and check that each control switch knob is in the correct position before entering the program. Until the red light goes out and the air pressure alarm is eliminated. Adjustable drill-bit guides and side fences position the dowel holes. This is because when the machine tool driven by the servo motor does not punch, the main motor is in a static state and does not consume power. Due to the limited depth of the throat, the common strokes in the Y-axis are 1250mm, 1500mm.

And a dedicated maintenance staff was set up to carry out scheduled maintenance. The punching head can automatically select the punching stroke according to the thickness of the plate and realize the pre-pressing function, which can reduce the punching stroke and increase the punching speed. (2) The inductance should be controlled between 1-2mm, too deep will cause the cores release stroke and resistance to increase, thus prolonging the springs reaction time. @media (max-width: 603px) {

Even if the waste is punched into the die, if stranded on top of the previous waste, it is easy to bounce out of the die due to vibration, the formation of waste bounce, so it must be scientifically selected mold. text-align: center; Carefully check that the upper and lower molds are of the same size before installation, and that the edges are in the same direction. Punching a square hole causes the edge to be turned up, the larger the hole the more obvious the turning of the edge, in this case the LASER secondary cutting is often considered (the customer can also be consulted on whether this distortion is acceptable). The pressure relay determines whether the pressure of the air source has reached the set value, if not, the CNC system will alarm. Glue anything in place with the Metabo 3000 glue gun. Molds are the main tools used to process sheet material. Operators shall not leave the machine or perform other work while the equipment is in operation. .trolley-totals .we-accept span.panel img { In China, the die material on the CNC punching machine is usually Cr12MoV and LD. Simply clamp the jig in position and use an electric or cordless drill with theRead more, Clarke CHT580 8 piece Double Cut Rotary Burr Set, Clarke CHT381 3pc. (2) Make the air or oil pressure meet the requirements of the machine tool. When the jaws are holding the workpiece in motion, they may be washed out and damaged, so a safe distance must be left between the machined part and the jaw. Generally speaking, hydraulic systems do not require frequent maintenance. The grinding feed should not exceed 0.015mm each time when sharpening, too much grinding will cause overheating and burning of the mold surface, which is equivalent to the annealing treatment, and the mold will become soft, which will greatly reduce the service life of the mold. After cleaning, spray some oil on the die and insert it into the die, and the concave die can also be inserted into the die. 2)Continuous punch( rectangular ) hole. Note: Demagnetize in time after sharpening, and adjust the height of the mold as before sharpening. The line is pressed either with a targeted line or with the entire bent line. For example, when using a cam die of 10 and a concave die of 10.3, 10.3-10=0.3 (hole diameter of the concave die hole diameter of the cam die = clearance), the clearance is 0.3mm. (2) The sensing switch bracket is loose or sensing distance is out of range. Typical representatives include Muratecs C series, Amadas Aries series, PEGA series, COMA series, etc. The CNC turret punch has four axes of motion: X, Y, T and C. The X-direction is parallel to the direction of the two jaws and the Y direction is parallel to the direction of the locating pin or column. But too much lubricating oil often stays in the upper die end surface, the strike during punching and cutting is easy to make the upper die end surface and waste to produce vacuum adsorption between the formation of slag, ie: waste rebound. Scribe a line down the centre of each board with a marking gauge. Carry-over on the head punch and adhesion means that under normal conditions, the upper die core and sheet material can not be disconnected in time or completely. (1) Increase the air pressure so that the lower limit can meet the working requirements of the machine. (3) Sometimes the mold is damaged due to the continuous production of slag and the slag overlap exceeds the strength limit of the mold, and the scrap rate due to slag is significantly increased when the production of single pieces or small quantities is high. Machine Mart Ltd 211 Lower Parliament Street, Nottingham NG1 1GN. (8) Other reasons such as mold clearance and accuracy. Privacy Policy | Terms and Conditions | Sitemap. (1) To ensure the accuracy of the processed sheet. Without the depth stops I can't use it for the job I bought this for. The use of the corresponding instructions not only makes the various types of machining easier but also less error-prone. The punch is mainly used to strike the die, it is the source of power for the punch and its own power is done by the hydraulic station. If the mold is sharpened more than 4 mm, it is necessary to consider changing the core of the mold, otherwise the convex mold will have less and less penetration into the concave mold. Clean heat sink fan dust and clean filter screen regularly. The clamping of the jaws moves the steel plate back and forth to the point where it needs to be stamped. Add hydraulic oil with the special oil filter to the oil level of 2/3 above 4/5 below. (3) The repositioning cylinder is controlled by two five-way solenoid valves, and the cylinder is fixed on the bracket connected with the bed. .trolley-totals .we-accept span.panel { The 5-piece chisel set contains 6, 10, 13, 19 & 25mm chisels. The workpiece is positioned on the CNC turret punch by means of the jaws and Y-directional locating pins or square locating blocks, which are placed on the jaws to determine the Y-directional position, and on the locating pins or square locating blocks to determine the X-directional position. The hardest part I found was working out which parts went where when drilling the matching holes. Prohibit the use of strong force on the hydraulic system to avoid subjecting the piping system and components to lateral force or internal stress, and be sure to protect the piping system. kerimantik
