[0002] At present, many parts on automobiles are produced by stamping dies. A stamping die is a special process equipment that processes metal or non-metal materials into parts or semi-finished products in cold stamping processing. However, in the actual use process, there are still some problems. For example, in order to meet the processing requirements of workpieces of different specifications, it is usually necessary to frequently replace the die according to the actual processing requirements. However, at present, most dies are fixed on the workbench by bolts, and this fixing method makes the disassembly and installation more cumbersome, thus increasing the time for die replacement and reducing the working efficiency of the device to a certain extent.

Furthermore, the upper die part installed on the outer surface of the middle of the shaft rod is driven to rotate until the upper die on it rotates to correspond to the replaced lower die, thereby further reducing the difficulty of die replacement and improving the actual work efficiency.

[0029] The fastening assembly 7 includes a driving mechanism 70 and a clamping mechanism 71 . The driving mechanism 70 is arranged on the side surface in the width direction of the base 1 . There are two clamping mechanisms 71 , and the two clamping mechanisms 71 are arranged in parallel in the middle of the driving mechanism 70 .

[0030] The driving mechanism 70 includes a cover plate 700, a motor 701, a pulley 702, a track 703, and a pulley 704. The side of the cover plate 700 is fixedly mounted on the surfaces of the ends of the two clamping mechanisms 71. The motor 701 is arranged on the outer surface of the cover plate 700. The middle part of the pulley 702 is fixedly mounted on the output end of the motor 701. The track 703 and the pulley 702 are meshed with each other. The middle part of the pulley 704 is rotatably mounted on the inner surface of the cover plate 700. The pulley 704 is transmission-connected to the pulley 702 through the track 703.

[0031] By setting up pulley 2 704, when pulley 1 702 is driven by motor 1 701 to rotate, the meshing track 703 will be driven to rotate, and the track 703 will drive pulley 2 704 to rotate, so that the middle part of pulley 2 704 rotates along the inner surface of motor 1 701, driving the bidirectional screw 711 in the clamping mechanism 71 fixedly connected to the middle part of pulley 2 704 to rotate, so that the slider 1 712 and the slider 2 713 thereon can clamp or move away from the lower mold 6.

[0032] Among them, the clamping mechanism 71 includes a frame plate 710, a bidirectional screw rod 711, a slider 1 712, and a slider 2 713. The bottom of the frame plate 710 is fixedly installed on the top surface of the middle part of the base 1, the two ends of the bidirectional screw rod 711 are rotatably installed on the inner surfaces on both sides of the frame plate 710, and the ends are fixedly installed on the middle part of the pulley 1 702.

The middle part of the second gear 85 is fixedly installed with the side end of the shaft rod 82.

[0034] The working process of the present utility model is as follows:

[0035] When it is necessary to replace the lower die 6, the staff can control the first motor 701 to start, so that the first pulley 702 connected to the output end of the first motor 701 rotates, driving the bidirectional lead screw 711 installed in the middle to rotate. The first slider 712 and the second slider 713 threadedly connected to the surface of the bidirectional lead screw 711 will slide along the inner surface of the frame plate 710 and move away from each other, so that the wedges installed on the surfaces of the first slider 712 and the second slider 713 are disengaged from the inside of both sides of the lower die 6, thereby canceling the clamping and fixing effect on the lower die 6. At this time, the lower die 6 is removed from the middle of the base 1, and then after placing a suitable die, the first motor 701 is controlled to rotate in the reverse direction, so that the first slider 712 and the second slider 713 approach each other to complete the fixing of the die. Through the above structure, it is possible to quickly install or disassemble the lower die 6 provided in the middle of the base 1, reduce the time for die replacement, and improve work efficiency.

[0036] After replacing the lower die 6, the staff can control the second motor 83 to start. The first gear 84 connected to the output end of the second motor 83 rotates, driving the meshing second gear 85 to rotate, so that the shaft rod 82 connected to the middle part of the second gear 85 rotates along the inner surface of the bottom ends of the two vertical plates 80, thereby driving the upper die member 81 installed on the outer surface of the middle part of the shaft rod 82 to rotate until the upper die on it rotates to correspond to the replaced lower die 6, further reducing the difficulty of die replacement and improving the actual work efficiency.
