Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to a metal product processing punching machine. Background Art

[0002] A punch press, also known as a press, is a piece of mechanical equipment widely used in industrial production. It is mainly used to perform stamping, stretching, bending, forming and other processing operations on metal, non-metal and other materials through molds.

[0003] The punch press adopts an automated production method and can realize high-speed and continuous stamping processing of metal products. In the prior art, when the punch press performs high-speed stamping on the metal workpiece, it instantly applies high-intensity shear force to the metal workpiece, causing stress concentration in the metal workpiece, causing part of the surface of the metal workpiece or tiny debris to splash out during punching. Since most punch presses are not equipped with protective devices, the splashed debris will cause harm to the staff and reduce the safety of the punch press during use. Therefore, it is necessary to redesign a metal product processing punch press to address the above problems. Summary of the invention

A clamping plate 15 is fixedly installed on the ends of the two connecting blocks 14, and an anti-skid pad 16 is fixedly installed on the inner walls of the two clamping plates 15. The two anti-skid pads 16 are made of rubber material, and the rubber material has good elasticity The properties of the material and the flexibility of the material make it possible to form a closer contact between the surface and the object, thereby increasing the friction and improving the friction coefficient. The outer walls of the two connecting sleeves 13 are slidably penetrated by fixing pins 17. The outer walls of the two connecting blocks 14 are provided with jacks that cooperate with the fixing pins 17. The outer walls of the two fixing pins 17 are provided with shifting blocks 18.

[0030] When the present invention is used, the lower mold can be placed on the upper end surface of the punching table 1 and placed between the two clamping plates 15. Then the motor 4 can drive one of the double-headed screws 3 to rotate. When rotating, one of the double-headed screws 3 can drive the transmission plate 5 on the same side to rotate. One of the transmission plates 5 can drive the other transmission plate 5 to rotate through the cooperation of two connecting rods 6 and the connecting plate 7. At this time, the other double-headed screw 3 can be rotated synchronously. When rotating, the double-headed screw 3 can drive the two movable sleeves 9 to move by cooperating with the limit rod 8. The two movable sleeves 9 are When moving, the first connecting frame 10 on the same side can be driven to move respectively, so that the two first connecting frames 10 can drive the connecting sleeve 13 to move through the cooperation of the connecting plate 11 and the second connecting frame 12, and the connecting sleeve 13 can drive the clamping plate 15 to move through the cooperation of the connecting block 14, so that the two clamping plates 15 can be close to each other, and the lower mold can be clamped through the cooperation of the anti-skid pad 16, so as to realize the convenient installation and fixation of the lower mold on the upper end surface of the stamping table 1, and the anti-skid pad 16 can increase the friction with the outer wall of the lower mold to improve the firmness during clamping;

[0031] When it is necessary to clamp and fix the lower molds of different shapes, the dial block 18 can be moved to drive the fixing pin 17 to move out of the socket, thereby releasing the fixing of the connecting block 14 inside the connecting sleeve 13, and then the connecting block 14 can be moved out of the connecting sleeve 13 to complete the disassembly. When installing the clamping plate 15, the connecting block 14 equipped with different types of clamping plates 15 can be slidably installed inside the connecting sleeve 13.

The interior of the part is provided with a fixed installation of the clamping plate 15. When the workpiece is stamped, the electric push rod 31 can drive the moving rod 33 to move through the cooperation of the moving block 32. At this time, the moving rod 33 can drive the sliding sleeve 26 to slide on the outer wall of the sliding rod 25, so that the sliding sleeve 26 can drive the baffle 28 to move upward through the installation frame 27 and extend upward through the corresponding collecting opening, so that the baffle 28 can be used to safely protect the front of the stamping table 1, thereby preventing the debris from splashing during stamping and causing harm to the operator (the initial position of the baffle 28 is as shown in FIG. Figure 1shown);

[0032] During the stamping process of the workpiece, the debris can fall through the two collecting openings into the collecting box 35 inside the collecting tank and be collected. When there are still metal powder and debris on the upper end surface of the stamping table 1, the fans 21 on both sides can blow the wind into the blowing pipe 23 through the cooperation of the connecting pipe 22, and the wind is blown out from the blowing pipe 23 through the blowing nozzle 24. Through the arrangement of the blowing pipe 23 and the blowing nozzle 24 on both sides, the wind blown out in opposite directions can blow the metal powder and debris through the two collecting openings into the collecting box 35. When the collecting box 35 needs to be removed from the When moving out of the collection trough, the baffle 28 can be extended upward to remove the obstruction of the collection box 35, and then the collection box 35 can be pulled out from the upper end surface of the support frame 34, and then the debris and powder inside the collection box 35 can be recycled. When the baffle 28 needs to be disassembled, the two fixing bolts 29 can be screwed first to disengage the two fixing bolts 29 from the outer wall of the mounting frame 27, thereby releasing the fixation of the baffle 28 inside the mounting frame 27, and then the baffle 28 can be moved out of the mounting frame 27 to complete the disassembly.
