The loading and unloading moving component 6 includes a pair of second lead screws 6-1. The second lead screws 6-1 are rotatably connected to the opposite side surfaces outside the equipment base 1. The second lead screws 6-1 are driven to rotate by a motor. A guide frame 6-2 is installed on the side surface of the equipment base 1. A moving frame 6-3 is installed on the outside of the second lead screw 6-1 and the outside of the guide frame 6-2. The moving frame 6-3 is connected to the second lead screw 6-1 by threaded cooperation. A transmission wheel 6-4 is arranged at one end of the second lead screw 6-1. A telescopic cylinder 6-5 is fixedly connected to the surface of the moving frame 6-3. A bracket 6-6 is connected to the output end of the telescopic cylinder 6-5. A plurality of base frames 6-7 are fixedly connected to the surface of the moving seat 5. A lower cold heading mold 6-8 is movably installed in the base frame 6-7. The opposite end surfaces of the lower cold heading mold 6-8 are fixedly connected to connecting blocks 6-9.

[0033] In this embodiment, in order to achieve the effect of rapid processing of batch loading and unloading of bolts, a loading and unloading moving component 6 is designed. A plurality of base frames 6-7 are fixedly connected to the surface of the moving seat 5. The lower cold heading mold 6-8 can be directly placed inside the base frame 6-7, and there is no fixed structure, so it can be directly taken out. During installation, the lower cold heading mold 6-8 is filled with bolts and then placed in the bracket 6-6 at the output end of the telescopic rod. The position of the bracket 6-6 can be adjusted by moving the moving seat 5. The interval distance of each movement is the same to ensure accurate positioning without deviation. When taking out the lower cold heading mold 6-8, the telescopic cylinder 6-5 is also started, and the lower cold heading mold 6-8 can be lifted up by docking the bracket 6-6 with the connecting block 6-9.

[0034] Specifically, in order to achieve a stable stamping effect, a driving pressure assembly 7 is designed, and a detachable upper cold heading die 7-3 is provided, so as to facilitate timely detection and timely handling of problems.

[0035] Furthermore, the driving pressure assembly 7 includes a hydraulic cylinder 7-1, the output end of the hydraulic cylinder 7-1 is connected to an upper frame 7-2, an upper cold heading die 7-3 is installed in the upper frame 7-2, and the upper cold heading die 7-3 is fixedly connected to the upper frame 7-2 by bolts.

The upper cold heading mold 7-3 can be inserted into the top frame 2, and a fixed connection method of bolts is adopted. The lower cold heading mold 6-8 can be taken out by removing the bolts, and the loading and unloading method is simple and firm.

[0037] Furthermore, a long groove 8 is formed on the upper end surface of the equipment base 1 , and a plurality of supporting rollers 9 are installed in the long groove 8 .

[0038] In this embodiment, the long groove 8 is opened at both ends of the upper surface of the equipment base 1, and support rollers 9 are installed in the long groove 8 to support the bottom of the base frame 6-7, increase the load-bearing capacity of the base frame 6-7, and avoid affecting the transmission of the moving seat 5 and the first screw 4.

[0039] Furthermore, the bracket 6-6 is in a C-shaped structure as a whole, and the bracket 6-6 is movably connected to the connecting block 6-9.

[0040] In this embodiment, the C-shaped structure enables the bracket 6-6 and the connecting block 6-9 to play a role of fitting and limiting, and will not slide or misalign.

[0041] Furthermore, the upper end surface of the support roller 9 is higher than the upper end surface of the equipment base 1, and the support roller 9 is in contact with the bottom surface of the base frame 6-7.

[0042] In this embodiment, the supporting rollers 9 need to protrude from the inside of the long slots 8 to ensure that they are all at the same plane height and the supporting base frames 6-7 maintain stable movement.

[0043] Furthermore, the transmission wheels 6 - 4 are connected by belt transmission.

[0044] In this embodiment, the transmission between the transmission wheels 6 - 4 is more stable and has a better mute effect through the transmission of the belt.

[0046] In this embodiment, the notches 10 are used to avoid the connection blocks 6-9 on both sides of the lower cold heading die 6-8 to avoid movement restriction.

[0047] When stamping is required, install the bolts into the lower cold heading die 6-8, start the telescopic cylinder 6-5, extend the output end of the telescopic cylinder 6-5, and then put the lower cold heading die 6-8 into the bracket 6-6 through the connecting block 6-9, and then start the telescopic cylinder 6-5 again to shrink the output end, and the lower cold heading die 6-8 enters the base frame 6-7, and then start the second screw 6-1 to adjust the position. When starting processing, start the first motor 3 to drive the first screw 4 to rotate, so that the movable seat 5 moves the position and drives the lower cold heading die 6-8 to align with the upper cold heading die 7-3, and then start the hydraulic cylinder 7-1, and extend the output end downward for stamping.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
