Description

Technical Field

[0001] The utility model relates to the technical field of forging, in particular to a forging clamp for a forging machine. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain forgings with certain mechanical properties, shapes, and sizes. Due to the large vibrations generated by the hammering of the forging machine, the forgings need to be clamped in advance to prevent them from falling off, which requires the use of a forging fixture for a forging machine. Therefore, the existing forging fixtures for forging machines have been continuously innovated and developed. Therefore, it can be seen that the current forging fixtures for forging machines basically meet people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN220073156U discloses a new type of special forging fixture for forging machines, which belongs to the field of forging machines. It includes a base plate, a base is fixedly provided on the upper end of the base plate, a card cover is slidably connected to the upper end of the base, an insert is fixedly provided on the lower end of the card cover, a first telescopic rod is fixedly provided on the left and right sides of the upper end of the base plate, a card box is fixedly provided on the upper end of the first telescopic rod, a second telescopic rod is fixedly provided inside the card box, a left clamp and a right clamp are fixedly provided on the right side of the second telescopic rod, and a clamp to be placed on the upper end of the card cover. Forging parts, the lower end of the card cover is clamped with a protective pad, and the first telescopic rod is used to conveniently drive the second telescopic rod to rise and fall, and the second telescopic rod is used to conveniently drive the left clamp and the right clamp to move left and right, so as to facilitate the left and right clamping of forged parts of different diameters, and conveniently clamp the forged parts at different heights, and facilitate the adjustment of the left clamp and the right clamp at any time during the forging process, thereby facilitating the forging work. By setting the telescopic rod and the clamp, the left clamp and the right clamp can be adjusted at any time during the forging process, thereby facilitating the forging work.

[0004] However, when the above device clamps the forging, since the clamp is a single arc surface, when the forging machine hammers the forging, the vibration generated spreads to the surroundings. Relying solely on the clamp to clamp and fix the two sides of the forging will inevitably result in an incomplete clamping range, which will cause the forging to fall off from both sides of the clamp after being hammered, thereby reducing the clamping effect of the equipment. Therefore, there is an urgent need for a forging clamp for a forging machine to solve the above problem. Utility Model Content

[0027] When using a forging fixture for a forging machine, the forging object is first placed between two groups of first clamps 6, and the two sides of the forging object are clamped and fixed by moving the first clamps 6. Then the servo motor 8 is powered on, and the output end of the servo motor 8 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the limit block 11 on the surface to move. The movement of the limit block 11 drives the support rods 12 on both sides to tilt. The tilt of the support rod 12 pushes the second clamp 7 to rotate. The second clamp 7 clamps four groups of the forging object by rotating on both sides of the first clamp 6. The forging object is clamped and fixed in six directions by the clamping mechanism, thereby improving the stability of the equipment in clamping the forging object during forging and preventing it from shaking.

[0028] See also Figure 1 、 Figure 4 and Figure 5 The surface of the support column 2 is fixedly connected with a connecting rod 13, the middle part of the connecting rod 13 is fixedly connected with a storage box 14, one side of the front of the storage box 14 is rotatably connected with a protective plate 15, the bottom of one side of the storage box 14 is fixedly connected with a first magnetic stone 16, and the bottom of the front of the protective plate 15 is fixedly connected with a second magnetic stone 17.

[0029] The storage box 14 can be opened by rotating the protective plate 15, and tools can be placed in the storage box 14. The storage box 14 is located on both sides of the bottom of the table body 1, which is convenient for the staff to take the tools in the storage box 14, and the first magnetic stone 16 on one side of the storage box 14 can be adsorbed with the second magnetic stone 17 on one side of the protective plate 15, so as to prevent the protective plate 15 from being opened due to vibration.

[0030] See also Figure 1 and Figure 2, one side of the top of the table body 1 is fixedly connected to a fixed plate 18, one side of the back of the fixed plate 18 is fixedly connected to a hydraulic cylinder 19, and one end of the hydraulic cylinder 19 is fixedly connected to both sides of the connecting plate 3, one side of the front of the fixed plate 18 is fixedly connected to a reinforcement block 20, and the bottom of the reinforcement block 20 is fixedly connected to the top of the table body 1, the middle part of the front of the connecting plate 3 is fixedly connected to a protective box 21, and the servo motor 8 is located on the inner wall of the protective box 21, the backs of the first clamping block 6 and the second clamping block 7 are fixedly connected to anti-slip pads 22, the backs of the first clamping block 6 and the second clamping block 7 are both curved surfaces, the first magnetic stone 16 is located on one side of the second magnetic stone 17, and the first magnetic stone 16 and the second magnetic stone 17 attract each other.

[0031] When the forging needs to be clamped and fixed, the connecting plate 3 is pushed to move by the extension and contraction of the hydraulic cylinder 19, so that the movement of the connecting plate 3 drives the first clamping block 6 to move, thereby clamping both sides of the forging. The reinforcement block 20 can reinforce the fixing plate 18 and the table body 1. The protective box 21 can protect the surface of the servo motor 8 to prevent impurities generated by colliding with the forging from damaging the servo motor 8. The anti-slip pad 22 can increase the friction between the forging and the first clamping block 6 and the second clamping block 7. The arc-shaped first clamping block 6 and the second clamping block 7 can better fit the two sides of the forging.

[0032] Working principle: when using a forging fixture for a forging machine, first place the forging object between the two sets of first clamps 6, and move the connecting plate 3 by the extension and contraction of the hydraulic cylinder 19, so that the first clamps 6 are pushed to both sides of the forging object to clamp it, and then the servo motor 8 drives the threaded rod 10 to rotate, thereby driving the support rod 12 to tilt, and after the support rod 12 tilts, it drives the second clamp 7 to rotate, so that the second clamp 7 is rotated to both sides of the forging object to perform secondary clamping and fixing on all sides of the forging object.
