Example 1

[0029] Referring to Figures 1-4 , Figure 1 A structural schematic diagram of a forging piece clamping mechanism suitable for forging machining is drawn. As shown in the figure, a forging piece clamping mechanism suitable for forging machining, comprising a mounting seat 10 and a U-shaped frame 110 mounted on the top of the mounting seat 10, further comprising,

[0030] A lifting mechanism 20 is installed on the U-shaped frame 110;

[0031] A rotating mechanism 30 is installed on the lifting end of the lifting mechanism 20;

[0032] An assembly seat 40 is installed on the rotating end of the rotating mechanism 30, and a mounting frame 410 is further installed on the top of the assembly seat 40;

[0033] The clamping arm 50 is symmetrically provided in two groups, and the clamping arm 50 is rotatably connected to the mounting frame 410. The clamping arm 50 includes a first clamping arm 510 rotatably connected to the mounting frame 410. The first clamping arm 510 is rotatably connected to a second clamping arm 520 at an end away from the mounting frame 410. The outer side walls of the first clamping arm 510 and the second clamping arm 520 are both fixedly connected to mounting plates 530. Hydraulic telescopic cylinders 540 are movably connected between adjacent mounting plates 530. An auxiliary clamping assembly is provided on the second clamping arm 520. The auxiliary clamping assembly includes an air pump 550 fixedly installed on the outer side wall of the second clamping arm 520. The second clamping arm 520 is hollow in the inner cavity. The output end of the air pump 550 is connected to a booster pipe 560 in communication with the inner cavity of the second clamping arm 520. A piston hole 570 is formed in the side of the second clamping arm 520 away from the air pump 550, and the piston hole 570 is in communication with the inner cavity of the second clamping arm 520. A piston rod 580 is slidably connected in the piston hole 570. A buffer pad 581 is provided on the end of the piston rod 580 away from the second clamping arm 520. A pressure relief valve 590 is further provided on the clamping surface of the second clamping arm 520. The extension length of the hydraulic telescopic cylinder 540 is then controlled to adjust the angle between the first clamping arm 510 and the second clamping arm 520, so that the second clamping arm 520 is fitted to the workpiece to be forged. The air pump 550 is turned on to increase the pressure in the hollow chamber of the second clamping arm 520. As the pressure in the hollow chamber of the second clamping arm 520 increases, the piston rod 580 is extruded. At this time, the buffer pad 581 at the end of the piston rod 580 abuts against the workpiece to be forged, further improving the stability of clamping. At the same time, as the air pump 550 is pressurized, when the pressure in the hollow chamber of the second clamping arm 520 exceeds a critical point, the pressure relief valve 590 is exhausted. The exhaust gas can assist in cooling the forged workpiece, which helps to improve the cooling efficiency of the forged workpiece;

[0034] A clamping adjustment mechanism 60 is installed at the intersection of the clamping arm 50 and the mounting frame 410.

[0036] The rotating mechanism 30 comprises a driving pinion 310 installed on the lifting plate 230, the top of the lifting plate 230 is further rotationally connected with a driven gear 320 engaged with the driving pinion 310, and the mounting seat 40 is fixedly installed on the top of the driven gear 320.

[0037] The clamping adjusting mechanism 60 comprises a gear 610 installed on the first clamping arm 510 through a rotating shaft and intersecting with the mounting frame 410, the telescopic cylinder 620 is installed on the mounting frame 410, the extension end of the telescopic cylinder 620 is connected with a tooth plate 630, and the tooth plate 630 is engaged with the two sets of gears 610.

[0038] The top of the mounting frame 410 is fixedly connected with a protective shell 640 arranged above the gears 610 and the tooth plate 630.

[0039] The clamping surfaces of the first clamping arm 510 and the second clamping arm 520 are provided with wear-resistant layers.

[0040] Working principle:

[0041] The utility model provides a kind of forging piece clamping mechanism suitable for forging processing, when using: the position of the lifting seat 220 and the lifting plate 230 is adjusted through the driving screw rod 210 on the lifting mechanism 20, then the extension length of the tooth plate 630 is controlled through the extension length of the telescopic cylinder 620, and then the rotation angle of the gear 610 is adjusted, so that the first clamping arm 510 is attached to the workpiece to be forged;

[0042] Then the extension length of the hydraulic telescopic cylinder 540 is controlled to adjust the angle between the first clamping arm 510 and the second clamping arm 520, so that the second clamping arm 520 is attached to the workpiece to be forged;

[0043] Then the air pump 550 is started to pressurize the hollow chamber of the second clamping arm 520, as the pressure in the hollow chamber of the second clamping arm 520 increases, the piston rod 580 is extruded, at this time the buffer pad 581 at the end of the piston rod 580 abuts against the workpiece to be forged, further improving the stability of clamping, and as the air pump 550 is pressurized, when the pressure in the hollow chamber of the second clamping arm 520 exceeds the critical point, the pressure relief valve 590 exhausts, the exhaust gas can assist in cooling the forged workpiece, which helps to improve the cooling efficiency of the forged workpiece.

[0044] The above is only a specific application example of the utility model, and does not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
