The installation direction of the two clamp shaft blocks 11 is staggered and opposite to each other. A first slide groove 12 is opened on the inner side wall of the lower end between the two clamp shaft blocks 11. The upper rear openings of the two clamp shaft blocks 11 are connected to the connecting block 6. A No. 1 slider 13 is slidably arranged in the first slide groove 12.

The sliding positions of the No. 1 connecting plate 142 and the No. 2 connecting plate 143 are fixed by the No. 3 bolt 145, and the first adjustment component 14 is used to adjust the position of the clamp block 15, and a No. 3 slider 17 is arranged in the groove of the clamp block 15, and a contact head 18 is arranged in the groove of the No. 3 slider 17; The abutment head 18 is connected to the No. 1 slider 13 through a hydraulic assembly 19. The hydraulic assembly 19 includes two first oil tanks 191. The two first oil tanks 191 are circumferentially installed in the grooves on the upper and lower sides of the No. 3 slider 17. The inner cavity of the first oil tank 191 is designed as a "convex"-shaped structure. The right side wall of the convex cavity of the "convex"-shaped structure of the inner cavity of the first oil tank 191 is designed with an oil outlet. A first plug body 192 is slidably connected to the first oil tank 191 through a spring. The top of the inner end of the first plug body 192 is connected to the abutment head 18.

The oil in the second oil tank 193 increases and pushes the second plug 194 to move outward in the second oil tank 193, and simultaneously drives the first slider 13 to move and adjust the position in the first slide groove 12. When the clamping position diameter of the parts in the cold heading stage is large, after the position of the contact head 18 is adaptively adjusted, the position of the first plug body 192 is adjusted, and the oil in the first oil tank 191 is squeezed into the second oil tank 193 through the hose and the valve. The increase in the oil in the second oil tank 193 pushes the second plug body 194 to move outward in the second oil tank 193, driving the No. 1 slider 13 to move and adjust the position in the first slide groove 12, and synchronously adjust the movement distance between the No. 1 connecting plate 142, so that the sliding distance of the connecting block 6 in the rotating sleeve 7 can be adjusted.

[0021] Example 3: Based on Example 2, please refer to Figures 1 to 13 , the method comprises the following steps: S1: first adjust the positions of the movable plate 9, the rotating frame 8 and the rotating sleeve 7 to the limit position, and then perform preliminary installation and adjustment on the connecting block 6 and the clamp shaft block 11; S2: Adjust the state of the first adjustment component 14, cooperate with the second adjustment component 16, the contact head 18 and the hydraulic component 19, and adjust the applicability of the position of the contact head 18 according to the shape and diameter of the clamping position of the actual processed part; S3: After the adaptability adjustment of the position of the abutment head 18, the oil in the first oil tank 191 and the second oil tank 193 changes, and the position of the first slide block 13 and the first connecting plate 142 is adjusted to complete the adaptive adjustment of the clamping speed; S4: Tighten the No. 1 bolt 141, the No. 2 bolt 144, the No. 3 bolt 145 and the No. 4 bolt 163, and close the connecting valves of the first oil tank 191 and the second oil tank 193 to complete the adjustment of the clamping position.

[0022] Working principle: When using the cold heading machine to stabilize the feeding mechanism, the operator first moves the movable plate 9 backward. During this process, the movable plate 9 drives the rotating sleeve 7 to deviate backward to the maximum position with the connection position of the rotating frame 8 as the center, so that the center point of the rotating sleeve 7 and the center point of the mold installation under the mold table 3 are in a horizontal position. Then, the threaded adjustment rod 5, the connecting block 6 and the clamp shaft block 11 are put in from the bottom of the installation box 10, and the connecting block 6 is slid into the rotating sleeve 7, and then the clamp shaft block 11 is installed on the inner convex column of the installation box 10, and then the connecting block 6 is slid upward in the rotating sleeve 7 to adjust the position, and adjusted to the threaded adjustment rod 5, the connecting block 6 is slid upward in the rotating sleeve 7 ... The top of the section rod 5 is connected to the opening and closing mechanism 4 and connected to the opening and closing mechanism 4 through a nut. At the same time, the position of the nut on the threaded adjustment rod 5 is screwed upward to the maximum position, and the preliminary installation is completed. Then the connection block 6 is slid to the bottom end in the rotating sleeve 7, so that the two clamp shaft blocks 11 are rotated upward to the maximum opening position with the convex column installation position in the installation box 10. Then the operator places the workpieces at different cold heading stages into the mold below the mold table 3, manually moves the positions of the two clamp blocks 15 relatively, so that the contact head 18 contacts the workpieces at different cold heading stages, and starts to adjust and calibrate the clamping position; On the basis of the above, when starting to adjust and calibrate the clamping position of the workpiece, when the clamping position diameter of the workpiece at different cold heading stages is greater than the distance between the current two contact heads 18, and the connecting block 6 cannot slide downward in the rotating sleeve 7 for adjustment, it is necessary to first loosen the No. 1 bolt 141 so that the distance between the No. 2 connecting plate 143 can be adjusted, thereby increasing the distance between the two contact heads 18, and then loosen the No. 2 bolt 144 so that the clamp block 15 can rotate to facilitate the subsequent position adjustment of the contact head 18, and at the same time loosen the No. 3 bolt 145 to facilitate the subsequent adjustment and calibration of the clamping position of the contact head 18. The No. 2 connecting plate 143 slides on the No. 1 connecting plate 142 to adjust the position. When the adjustment and calibration are opened, after the contact head 18 conflicts with the clamping position of the workpiece, Then open the valves of the first oil tank 191 and the second oil tank 193, and continue to move the clamp 15 to relative contact, so that the first plug body 192 connected to the contact head 18 slides outward in the first oil tank 191 to adjust the position. At this time, the contact head 18 is adaptively adjusted to the corresponding position according to the clamping position diameter of the processed parts in different cold heading stages. At the same time, when a concave and convex section appears at the clamping position, after loosening the No. 4 bolt 163, the No. 3 slider 17 is adjusted forward or backward on the No. 2 slider 162 to match the corresponding concave and convex position. Then, the No. 4 bolt 163 is tightened to make the No. 2 slider 162 move outward in the second slide groove 161, and the No. 3 slider 17 is fixed in position to complete the adaptive adjustment of the contact head 18.

[0023] In the above process, after the adaptive adjustment of the position of the contact head 18 is completed, the position of the first plug body 192 is adjusted, and the oil in the first oil tank 191 is squeezed into the second oil tank 193 through the hose and the valve. The increase in the oil in the second oil tank 193 pushes the second plug body 194 to move outward in the second oil tank 193, and simultaneously drives the No. 1 slider 13 to move and adjust the position in the first slide groove 12. At the same time, when the two No. 1 sliders 13 move, they drive the two No. 1 connecting plates 142 to slide outward, and synchronously make the No. 2 connecting plate 143, with the clamp block 15 and the second The connection point of connecting plate No. 143 is rotated and offset outward, thereby increasing the distance between the top of connecting plate No. 142. At the same time, in this process, connecting plate No. 2 slid to the corresponding position on connecting plate No. 142 and reduced the distance between clamp shaft block 11 and clamp block 15. Then, the position of connecting block 6 is adjusted upward in rotating sleeve 7 to complete the adjustment of clamping speed. Subsequently, bolt No. 141, bolt No. 2 144 and bolt No. 3 145 are tightened, and the oil valves of the first oil tank 191 and the second oil tank 193 are closed synchronously to complete the adjustment and calibration of the clamping position.
