DETAILED DESCRIPTION

[0018] The following is a specific embodiment of the utility model and is further described in combination with the drawings, but the utility model is not limited to these embodiments.

[0019] Embodiment one:

[0020] A type of clamp for forging, such as Figs. 1 to 3 As shown, it includes a drive unit 3, a gripper base 1, and two gripper fingers 2 arranged opposite to each other. Both gripper fingers 2 are rotatably mounted on the gripper base 1. The drive unit 3 is used to drive the two gripper fingers 2 to perform opening and closing movements.

[0021] Specifically, the drive unit 3 includes a drive cylinder 31, a slider 32, at least two connecting rods 33, and two connecting arms 34. The drive cylinder 31 is mounted on the gripper seat 1, and the output end of the drive cylinder 31 is connected to the slider 32. The slider 32 is slidably disposed on the gripper seat 1. The gripper seat 1 has a first groove 6. One end of the slider 32 is slidably disposed in the first groove 6. The gripper seat 1 has a support part 8, which is T-shaped. The support part 8 has a second groove 7. The first groove 6 and the second groove 7 are arranged opposite to each other. The other end of the slider 32 is slidably disposed in the second groove 7. When the output end of the drive cylinder 31 extends or retracts and drives the slider 32, both ends of the slider 32 slide along the first groove 6 and the second groove 7, respectively. The guide effect of the first groove 6 and the second groove 7 on the slider 32 ensures the stability of the slider 32 during sliding and improves the reliability of the structure.

[0022] In this embodiment, there are four connecting rods 33, which are distributed relatively on both sides of the connecting arm 34. One end of two connecting rods 33 is rotatably connected to one side of the slider 32, and one end of the other two connecting rods 33 is rotatably connected to the other side of the slider 32. The other end of two connecting rods 33 is rotatably connected to one end of one connecting arm 34, and the other end of the other two connecting rods 33 is rotatably connected to one end of the other connecting arm 34. The two gripper fingers 2 are respectively connected to the other end of the corresponding connecting arm 34. The middle part of both connecting arms 34 is rotatably connected to the gripper seat 1. When the driving cylinder 31 drives the slider 32 to slide, the slider 32 drives the connecting arm 34 to rotate through the connecting rods 33. As the connecting arm 34 rotates, it drives the gripper fingers 2. The two gripper fingers 2 move closer to each other or further away from each other, thereby realizing the opening and closing of the gripper fingers 2.

[0023] In this embodiment, the gripper finger 2 and the connecting arm 34 are connected by bolts 9. The connection by bolts 9 can not only effectively ensure the stable connection between the gripper finger 2 and the connecting arm 34, but also facilitate the removal of the gripper finger 2, making it convenient for replacement and maintenance of the gripper finger 2 in the future.

[0024] Each of the two gripper fingers 2 is provided with a first gripping groove 4 and a second gripping groove 5. The first gripping groove 4 and the second gripping groove 5 on the two gripper fingers 2 are arranged opposite to each other. The first gripping groove 4 and the second gripping groove 5 are different in size and are distributed along the length direction of the gripper fingers 2.

[0025] When the two jaw fingers 2 are closed, the two first clamping grooves 4 cooperatively form a space for clamping the blank, and the two second clamping grooves 5 cooperatively form a space for clamping the blank, so as to clamp the blank.

[0026] It should be noted that, since the first clamping groove 4 and the second clamping groove 5 are different in size, the jaw fingers 2 can adapt to clamp blanks of different diameters and adapt to the change in the diameter of the blank during the forging process.

[0027] The first clamping groove 4 and the second clamping groove 5 are both semicircular, and the semicircular structure can more closely fit the outer surface of the blank, thereby providing stable and uniform clamping force to the blank and ensuring the stability of the clamping of the blank.

[0028] Embodiment Two:

[0029] A clamping device comprises a mounting seat 10 and a plurality of jaw fingers, the plurality of jaw fingers are all mounted on the mounting seat 10, and the plurality of jaw fingers are uniformly distributed along the length direction of the mounting seat 10, that is, the spacing between adjacent two jaw fingers is the same.

[0030] It should be noted that, during the forging process, only the mounting seat 10 needs to be driven to move by a driving source such as a pneumatic cylinder or an oil cylinder, and the mounting seat 10 simultaneously drives the plurality of jaw fingers and the corresponding clamped blanks to move, so as to simultaneously move a plurality of blanks and meet the forging processing requirements of multiple stations, thereby improving the production efficiency.

[0031] The specific embodiments described herein are merely illustrative of the spirit of the present application; those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
