How many degree adjustment steps should be made for stamping presses? Rush 5

1. Punching force p = circumference xt material thickness x shear strength.

Punching force = material thickness) x shear strength 440 = 109824 N = 11 tons. According to 16t selection.

2. The equipment should not only look at the tonnage, but also look at the size of the countertop.

1.After the punching force (punching force) is calculated, the thickness of the material should also be considered, if the plate is too thick, more than 10mm, above, choose a 100t press; 80t press is optional for less than 10mm.

2.The closing height of all presses has an adjustment range, and the closing height of the die is within the closing height adjustment range of the press, and the press can be adjusted. If the closing height of the mold is lower than the minimum closing height of the press, the closing height of the mold should be adjusted by adding a backing plate.

First ensure the 700KN (70 tons) requirements, that is, the selection of more than 80t punch, the closing height of the 80t punch is between 280 and 380, and a fixed plate needs to be added under the mold to raise the mold. The minimum number of pads is 280-167=113, and it is recommended to add it to 143

Energy-saving, high efficiency, high precision. The mechanical structure is simple. The volume and noise are relatively small. Because of the small number of manufacturers, the price is currently at least twice as high.

The advantage of the servo press is that it is driven by a switched reluctance servo motor from Kehui.

1. High efficiency and energy saving. There is no clutch friction energy consumption, no flywheel idling energy consumption, coupled with the high efficiency of the motor itself, making the servo press efficient and energy-saving, in accordance with the requirements of the laws and regulations of the national "Energy Conservation Law", the energy-saving press will be forced to eliminate the traditional press with high energy consumption; For example, the switched reluctance servo screw press is more energy-efficient than the friction screw press, and a document has been issued to force the elimination of the friction press.

2. Intelligent automatic numerical control. The operation of the press is controlled by high-speed computer intelligence, which can be fully automated without manual operation.

3. High mold life. The pressure is numerically controlled, and the mold will not be overloaded, worn and damaged.

4. The products are precision formed, with small tolerances and high precision. The pressure is stable and numerical, the wear of the mold is reduced, the products are precisely formed under the precise numerical control, the forgings are less flash, the tolerance is small, the precision is high, and the less cutting processing can be realized, and there is no need for subsequent processing such as turning, milling, planing, etc., such as the tooth shape of the column gear and bevel gear can be directly formed and produced.

5. High reliability of the equipment. The equipment has no wearing parts, the motor rotor has neither windings, nor conductors, and no permanent magnets, which is higher than the strength of permanent magnet servo motors, strong and reliable, impact-resistant, and the maintenance-free equipment effectively saves maintenance personnel and maintenance man-hours.

6. Intelligent mold adjustment. The fuselage is equipped with a tonnage meter, which can be adjusted under pressure control, and when the slow mold adjustment and close distance mold matching, it is not stuffy, and there is no need to set up special mold adjustment equipment and personnel, which saves the labor and man-hours of mold adjustment.

7. Information management. The process parameters are numerically controlled in real time, and the real-time feedback is provided by the communication network, which realizes the information control of product quality and the traceability of product quality.

8. Resource-saving and environment-friendly. There is no need for permanent magnet rare earth materials, which saves rare and valuable resources and avoids the damage to the environment caused by mining rare earths.

9. The human-computer interface is interactive. The motor is digitally controlled, and the user can input simple displacement and speed parameters to realize the intelligent flexible process curve numerical control, and the user does not need to compile the process curve, which is extremely convenient to use.

10. The structure of the equipment is extremely simple, with low cost of motor-deceleration mechanism-brake-working mechanism.

Due to the limitation of production output, the current switch reluctance servo press is: small tonnage is slightly more expensive than domestic ordinary presses, medium tonnage is the same as domestic ordinary presses, large tonnage is lower than domestic ordinary presses, large, medium and small tonnage presses are lower than foreign ordinary presses. After the formation of large-scale production, the ** of the switched reluctance servo press will be lower than that of the ordinary press.

The ability of metal materials to resist elastic deformation when stressed is called stiffness, and the "elastic modulus" reflects the stiffness of the material or mechanism, and the elastic deformation of the material or mechanism with good stiffness is small when subjected to force. For example, if the stiffness of the turning tool holder used in the lathe is poor, the parts that come out of the lathe may be small, which will affect the machining accuracy.

The force of the press is larger when working, and the force is mostly in tons, and the gap between the punches and dies during stamping is in microns, and the elastic deformation of the press is slightly larger, which will cause "gnawing the die" and scrap the expensive die, so the stiffness of the press plays a more important role in the stamping production.

The open tilting press is generally a mechanical rigid clutch, which does not have the function of a slider stopping at will like a friction clutch. When this kind of punch is installed in the mold, it is necessary to use the "adjustment" mode, dial the universal switch to this gear, and use the climbing rod to move the flywheel to drive the slider up and down to move the mold for mold calibration. When installing the mold, the slider is adjusted to the bottom dead center position, and after the mold is installed, the flywheel slider moves back and forth to confirm that the mold is installed correctly (after the mold is tightened, the guide pillar and the guide sleeve can be accurately matched without stagnation) and then the machine can be started and punched.

During the test punch, the upper and lower dies are not closed at the bottom dead center, and the height of the club is slowly adjusted to close until the sheet can be stamped down normally and the club can be locked.

1. After the hydraulic punch is corrected, install the anchor bolts, and then pour concrete, and after the concrete is completely solidified, tighten the nuts of the anchor bolts evenly, and then use the level to recalibrate the levelness of the workbench, and the grounding wire should be properly connected.

2. The hydraulic punch must be completely solidified before it can start working.

3. After the installation of the hydraulic punch, wash off the anti-rust grease on the surface of the hydraulic punch with kerosene, pay attention not to damage the surface of the paint when cleaning, and clean the oil holes, oil circuits and oil marks at the same time, and keep cleaning frequently, and do not use metal or abrasive cloth when scrubbing.

1. Before installation, carefully check whether the mold is complete, and whether the necessary protective devices and other accessories are complete.

2. Check the closing height of the 125-ton high-equipped hydraulic punch and the mold to ensure that the closing height of the mold used is between the large and small closing height of the press.

3. When using the discharge device of the press, it should be temporarily adjusted to a high position to avoid being bent when adjusting the closing height of the press.

4. When installing and adjusting the mold, the small press (nominal pressure below 150 tons) is required to pull the flywheel by hand to drive the slider to move up and down for operation; For the power control of large presses, the micro action button is used to move, and the foot switch is not allowed to operate.

What is a pneumatic punch? Pneumatic punch is a kind of high-speed stamping equipment with high punching accuracy and fast speed, and uses a compressor to produce gas. Compared with the ordinary punch, the pneumatic punch adopts advanced photoelectric protection technology, which is the use of pneumatic clutch brake type punch equipment, which realizes the mutual cooperation of computer counting and program, and greatly improves the work efficiency.

Pneumatic punch press structure.

The pneumatic punch is mainly composed of a fuselage, a pneumatic clutch, a slider and a microcontrol system.

1. Fuselage: cast as one with the workbench, the slider reciprocates up and down in the guide rail on the pneumatic punch body, adjusts the gap between the guide rail and the slider by the top wire, and tightens the cap after adjustment.

2. Clutch: Composite dry pneumatic clutch is adopted, the flywheel has a built-in bearing and the clutch, and the sealing plate is fixedly combined, and the air is pressed into the clutch by the solenoid valve when the button is pressed, and the power of the flywheel is transmitted to the crankshaft for work.

3. Slider: connecting rod and ball head adjustment screw is to transform the circular motion of the crankshaft into reciprocating motion, ball head screw can adjust the clamping strength and adjust the height of the mold, the lower end of the slider is made of the mold handle hole, and the mold can be fastened when decorating, and the large mold can be equipped with a stripper hole on both sides of the template hole and the slider adjustment hole equipped with a stripping device, and the ejector seat on both sides can be adjusted according to the height of the mold to realize the automatic stripping work.

4. Operating mechanism: controlled by the microcomputer, the status mode is displayed by the panel, and when the status bar shows the inch, the machine can be started synchronously with both hands to achieve 360 degrees of arbitrary stop. Movement, synchronous start time is seconds, when starting the safe stroke or continuous work, the inch kinetic energy should be used to point the hour hand of the display screen to 12 o'clock, or the observation angle table 12 o'clock, plus or minus 20 degrees can be started; When working continuously, you must press and hold the start button with both hands to make the machine run continuously for 5-7 years to achieve continuous work.
