[0037] Embodiment 3

[0038] Reference Figure 1-8 As shown, based on the technical solution of the first embodiment, a clamping table of a cold heading machine, for the specific structural design of the clamping mechanism 2, is combined with Figure 2 and Figure 3It can be seen that the clamp seat 6 is movably mounted on the slide bar 8, that is, the clamp seat 6 can rotate circumferentially and move axially along the slide bar 8, and the two ends of the slide bar 8 are respectively fixed on two mounting seats 1. The two ends of the slide bar 8 are respectively provided with mounting holes 801 for screwing the mounting seats 1. The two mounting seats 1 are both arranged on a horizontal fixed plate 4. In order to limit the circumferential rotation of the clamp seat 6, a pressure block 9 is installed on the fixed plate 4, and a horizontal plate of the clamp seat 6 is provided below the pressure block 9. The upper surface of the horizontal plate and the lower surface of the pressure block 9 are parallel to each other and leave a movable gap so that they can move in the horizontal direction along the lower surface of the pressure plate, that is, the clamp seat 6 can only move axially along the slide bar 8.

[0039] Reference Figure 5 and Figure 6 It can be seen that a sleeve wheel 7051 is fixed on one end of the eccentric adjustment column 705, and the other end of the eccentric adjustment column 705 is fixed in the rotation adjustment hole on the second clamp handle 7012. The sleeve wheel 7051 is movably sleeved in the rotation adjustment part processed on the first clamp handle 7011. The relative position spacing between the first clamp handle 7011 and the second clamp handle 7012 can be adjusted and can rotate relative to each other. Further, one end of the eccentric movable block 10 is provided with a movable wheel 11 that abuts against the bottom of the pressure plate. The movable wheel 11 is fixed to one end of the eccentric movable block 10 through a third rotating shaft 12 and abuts against the bottom of the second pressure plate 3032. The other end of the eccentric movable block 10 is connected to the clamp seat 6 through a compression spring. In addition, the clamp seat 6 is provided with a fixing frame 16, and the fixing frame 16 is threadedly connected to the adjusting rod 13, and the adjusting rod 13 is sheathed with a compression spring. The end of the eccentric movable block 10 is processed with a limiting groove matching the size of the compression spring. The adjusting rod 13 is set on the fixing frame 16 through an adjusting screw 15, and the degree of compression of the compression spring can be adjusted by rotating the thread.

[0040] Furthermore, the clamp assembly 7 further comprises a second clamp assembly 702 having the same structure as the first clamp assembly 701, the second clamp assembly 702 comprises a third clamp handle 7021 and a fourth clamp handle 7022, the third clamp handle 7021 and the second clamp handle 7012 are connected via a rotating pressure shaft 706, and the fourth clamp handle 7022 and the third clamp handle 7021 are alternately arranged and connected via the second rotating pressure shaft 706. Figure 2As shown, the two rotating pressing shafts 706 are respectively fixed to the middle parts of the two eccentric movable blocks 10 and are movably mounted on the vertical plate of the clamp seat 6. The vertical plate and the horizontal plate together form an L-shaped clamp seat 6. One of the rotating pressing shafts 706 passes through the pressing shaft rotation holes on the second clamp handle 7012 and the third clamp handle 7021 and is rotatably connected to the clamp seat 6. The other rotating pressing shaft 706 passes through the pressing shaft rotation hole and the cushion sleeve 22 at the right end of the fourth clamp handle 7022 and is rotatably connected to the clamp seat 6. The rotation adjustment hole and the pressing shaft rotation hole are connected through a locking groove 709. The locking groove 709 is provided with two locking threaded holes 708, which can respectively lock the rotation adjustment hole and the pressing shaft rotation hole. The locking threaded hole 708 passes through the upper and lower ends of the second clamp handle 7012 or the fourth clamp handle 7022.

[0041] Working principle: Combination Figure 8 As shown, when the cold heading machine is working normally, the rotation of the first rotating shaft 5 drives the cam 302 to rotate. When the large diameter of the cam 302 rotates and hits the pressing wheel 1801, the pressing arm seat 18 moves upward, and at the same time drives the first pressing plate 3031 fixed on the pressing arm seat 18 to press downward, and also drives the second pressing plate 3032 fixed on the first pressing plate 3031 to press downward, and the second pressing plate 3032 presses the movable wheel 11 downward to rotate the eccentric movable block 10. At the same time, the compression spring on the other end of the eccentric movable block 10 will be tightened, and the rotation of the eccentric movable block 10 causes the rotating pressing shaft 706 to rotate, thereby driving the first clamp handle 7011 and the second clamp handle 7012 to rotate. The two clamp handles 7012 are opened, and when the first clamp handle 7011 and the second clamp handle 7012 are opened, the left clamp arm 703 and the right clamp arm 704 are also opened and lifted, which can effectively avoid the stamping impact of the mold and ensure that the mold will not hit the clamp assembly 7 during stamping; when the small diameter rotation of the cam 302 hits the pressing wheel 1801, the pressure of the cam 302 on the pressure arm assembly 303 is reduced, and at the same time, the compression spring recovers from the tensioned state and generates a reaction force, so that the eccentric movable block 10 reverses and resets, thereby driving the first clamp handle 7011 and the second clamp handle 7012 to reset and close, and the pressure arm assembly 303 is also reset.
