[0030] The top of the middle cross frame 6 is fixedly provided with two groups of angle brackets 601, and the top of each angle bracket 601 is fixedly provided with an electric cylinder 602; the telescopic end of the rear electric cylinder 602 is fixedly provided with a flat guide strip 603, and the telescopic end of the front electric cylinder 602 is fixedly provided with a conforming guide strip 604; the two groups of angle brackets 601 are respectively aligned with the two groups of conveying belts 503.
[0031] The two sides of the flat guide strip 603 and the conforming guide strip 604 are integrally provided with downwardly turned corner structures.
[0032] The U-shaped block 507 conforms to the flat guide strip 603.
[0033] The top of the conforming guide strip 604 is a multi-faceted module structure.
[0034] As shown in Figures 1-5 The principle of processing is that the hydraulic machine 3 is started to push the cold heading upper die 4, the cold heading upper die 4 is used to approach the cold heading lower die 2 to perform cold heading processing on the workpiece; the rear end of the workpiece can be attached to the demolding elastic rod 201, and the workpiece is elastically clamped by the clamping stress generated by the demolding elastic rod 201 and the cold heading upper die 4, and the workpiece is fed;
[0035] At the same time that the cold heading upper die 4 pushes the workpiece to contact the demolding elastic rod 201, the two groups of electric cylinders 602 are simultaneously retracted, the flat guide strip 603 and the conforming guide strip 604 are lowered, and then the rod part bracket 506 and the supporting piece 508 are naturally lowered by gravity to release the lifting of the workpiece; the rear end of the workpiece contacts the demolding elastic rod 201, and the elastic stress automatically maintains positioning and continues to move backward to ensure that the workpiece will not fall, and then the workpiece can be moved backward to cold heading.
[0036] Embodiment 2:
[0037] On the basis of embodiment 1, the driving motor 502 is started to drive the H-shaped wheel 501 to rotate, and the conveying belt 503 is conveyed to one work station to complete the feeding; a proximity switch is arranged above the base 1 to contact the supporting piece 508 below, and automatic positioning is realized after each feeding.
[0038] The specific use mode and effect of the embodiment:
[0039] In use, the screw element needs to be manually supplemented, and one workpiece is supplemented each time;
[0040] As Figure 1 The cold heading upper die 4 is used to move close to the cold heading lower die 2, so that the workpiece can be cold heading processed;
[0041] During the movement of the cold heading upper die 4, the two groups of electric cylinders 602 are synchronously contracted, the plane guide bar 603 and the conforming guide bar 604 are lowered, and then the rod part bracket 506 and the supporting sheet 508 are naturally lowered by gravity, so that the workpiece is lifted; the rear end of the workpiece contacts the demolding elastic rod 201, the elastic stress is automatically maintained positioning and continues to move backward, so that the workpiece cannot fall off;
[0042] Conversely, after completing the cold heading once, the hydraulic machine 3 is contracted to reset the cold heading upper die 4, the demolding elastic rod 201 pushes the workpiece to automatically reset, finally the cold heading upper die 4 is separated from the workpiece, and the workpiece will lose the clamping and naturally fall off; during this period, the two groups of electric cylinders 602 are controlled to extend, the plane guide bar 603 contacts the U-shaped block 507 to lift the rod part bracket 506, the rod part bracket 506 bears the rod part of the workpiece, the conforming guide bar 604 contacts the auxiliary supporting block 509 to lift the supporting sheet 508, and the supporting sheet 508 bears the end part of the workpiece;
[0043] The driving motor 502 is started to drive the H-shaped wheel 501 to rotate, and the conveying belt 503 is conveyed to one work position, so that the feeding can be completed;
[0044] Since each cold heading step will cause the shape of the end part of the workpiece to change, when the workpiece returns to the original supporting sheet 508, the workpiece will be inclined, and the workpiece cannot be guaranteed to be pushed horizontally in the next step, therefore, the top of the conforming guide bar 604 is made into a guide shape suitable for the change of the step, when the workpiece is fed, the height of the rod part bracket 506 is unchanged, the auxiliary supporting block 509 automatically adjusts upward and downward along the top of the conforming guide bar 604, so that the workpiece after feeding can be guaranteed to be in a horizontal state, and the rear end of the workpiece can be attached to the demolding elastic rod 201 during the cold heading process.
