This cold-state forming process method is called cold stamping, simply referred to as stamping. When processing automobile workpieces, a stamping device is required.

[0003] With the increasing complexity of automobile stamping parts and more stamping processes, in the specific production process, multiple processes are required for stamping and forming. In the prior art, these processes need to be operated separately, which takes a long time and the production efficiency of automobile workpiece processing is not high. Content of the Utility Model

The transfer mechanism 4 includes a first motor 41, the first motor 41 is installed on the base 1, the output end of the first motor 41 is connected to a lead screw 42, a nut pair 45 is connected to the lead screw 42, a first electric telescopic rod 43 is installed on the nut pair 45, the output end of the first electric telescopic rod 43 is connected to a first electromagnet 44, a grinding mechanism 5 is provided on the base 1, a chute 14 is provided on the base 1, a third motor 8 is slidably fitted in the chute 14, the output end of the third motor 8 is installed with a fourth electric telescopic rod 15, and the output end of the fourth electric telescopic rod 15 is connected to a second electromagnet 16. When grinding the edge of the workpiece, extend the two telescopic rods so that the edge of the workpiece is aligned with the grinding mechanism. When it is necessary to replace other edge surfaces for grinding, first cut off the power supply of the first electromagnet 44, only the second electromagnet 16 adsorbs the workpiece, then control the third motor 8 to rotate, and after rotating to the grinding surface, perform the grinding operation in the same way.

[0025] The stamping die 2 includes a die holder 21 and a stamping plate 22. The die holder 21 is connected to the base 1, and the stamping plate 22 is connected to the output end of the hydraulic rod 33. A female die 23 is provided on the die holder 21, and a male die 24 is connected to the lower end of the stamping plate 22. The female die 23 and the male die 24 are in corresponding positions and cooperate with each other. The female die 23 and the die holder 21, as well as the male die 24 and the stamping plate 22, are fixedly connected by screws. Different stamping models can be replaced according to the shape of the automotive workpiece. The grinding mechanism 5 includes a grinding frame 51. The grinding frame 51 is connected to the base 1. A second motor 52 is installed on the grinding frame 51. The output end of the second motor 52 is connected to a grinding roller 53. When the second motor 52 works, it drives the grinding roller 53 to rotate to grind the edge of the workpiece. A cutting knife 7 is installed on the stamping plate 22. The cutting knife 7 and the edge of the female die 23 are in corresponding positions and cooperate with each other. As the iron sheet is stamped into an automotive workpiece, the stamping plate 22 approaches the die holder 21, and the edge of the stamped part cooperates with the cutting knife 7 and the edge of the female die 23, so as to cut off the excess iron block at the edge of the workpiece. Support frames 6 are installed on the base 1 at symmetric positions before and after the stamping die 2. The lead screw 42 rotates and cooperates within the support frame 6. After the automotive workpiece is pushed out of the die holder 21, first control the first electric telescopic rod 43 to extend, so that the first electromagnet 44 at its upper end approaches the lower surface of the workpiece, and energize the first electromagnet 44 so that the first electromagnet 44 can firmly suck the automotive workpiece. As the first motor 41 works, the driving nut pair 45 moves to the right on the support frame 6 to the position of the grinding mechanism 5. Control the operation of the first electric telescopic rod 43 to make the cutting edge of the workpiece close to the grinding belt 55 for grinding. The driving mechanism 3 includes two columns 31. The two columns 31 are connected to the base 1. A through groove 32 is provided on the column 31, and a hydraulic rod 33 is installed in the through groove 32. The hydraulic rod 33 drives the stamping plate 22 to move up and down through its telescopic movement, so as to complete the stamping operation of the workpiece. A second electric telescopic rod 9 is connected behind the push plate 12. The second electric telescopic rod 9 is connected to a fixing plate 10 below.

A third electric telescopic rod 13 is installed at the lower end of the U-shaped plate 11. The third electric telescopic rod 13 is connected to the inner bottom end of the female die 23. After the iron sheet is stamped into an automotive workpiece, the third electric telescopic rod 13 extends to push the U-shaped plate 11 upward to push the workpiece out of the die holder 21, and then make the second electric telescopic rod 9 extend to push the workpiece out of the U-shaped plate 11. With the use of the transfer mechanism 4, the workpiece after stamping and shearing is brought to the grinding mechanism 5 to grind the edge.

[0026] In use, first place the metal plate on the die base 21 of the stamping die 2, make the hydraulic rod 33 work to drive the stamping plate 22 to move downward, press the iron sheet into the required shape, the stamping plate 22 is close to the die base 21, and the edge of the stamping part cooperates with the edge of the cutting knife 7 and the female die 23, so as to cut off the redundant iron block at the edge of the workpiece and cut the automobile workpiece. Then, the hydraulic rod 33 works again to drive the stamping plate 22 to disengage from the die base 21, control the third electric telescopic rod 13 to do an extension movement to push the U-shaped plate 11 upward, push the workpiece out of the die base 21, and then make the second electric telescopic rod 9 do an extension work to push the workpiece out of the U-shaped plate 11. At this time, the first electric telescopic rod 43 and the fourth electric telescopic rod 15 do an extension movement to make the first electromagnet 44 and the second electromagnet 16 at their upper ends close to the lower surface of the workpiece, energize the first electromagnet 44 and the second electromagnet 16, so that they can firmly suck the automobile workpiece. With the operation of the first motor 41, the driving nut pair 45 moves rightward on the support frame 6 to the grinding mechanism 5 position, control the first electric telescopic rod 43 and the fourth electric telescopic rod 15 to work to make the cutting edge of the workpiece close to the grinding roller 53, and at the same time, the second motor 52 works to drive the driving roller 53 to rotate, so as to drive the grinding roller 53 to rotate to grind the edge of the workpiece. When it is necessary to grind the other side, cut off the power supply of the first electromagnet 44, energize the second electromagnet 16, drive the workpiece to rotate by the third motor 8, and then energize the first electromagnet 44 to continue grinding, so as to complete the processing of the automobile stamping workpiece.
