Description

Technical Field

[0001] The utility model relates to the technical field of forging, in particular to a jaw clamping device of a forging manipulator and a forging manipulator. Background Art

[0002] A forging manipulator is a large, essential auxiliary machine used in forging workshops to forge heated forging blanks. It consists of five components: a clamping mechanism, a rotating frame, a lifting mechanism, a gantry travel mechanism, and a gantry slewing mechanism. Used to clamp dies or forgings during the forging process, the forging manipulator reduces labor intensity and improves production efficiency.

[0003] The clamping mechanism of the existing forging manipulator is a crab-shaped jaw, such as Figure 1 As shown, the following defects exist: first, it is mainly used for clamping and transporting forging dies, and its scope of use is limited; second, when it clamps rectangular forgings, due to the small clamping area, the surface of the hot forgings is easily damaged, resulting in surface quality defects of the forgings; third, when it clamps shaft forgings, because the single clamp only has a line of contact with the forging, the hot forgings are easy to fall, posing a safety hazard. Utility Model Content

[0004] In order to overcome the technical defects of existing forging manipulators, such as limited use range, easy clamping of rectangular forging surfaces, and easy falling of shaft and rod forgings, the utility model provides a forging manipulator jaw clamping device and a forging manipulator.

[0005] The utility model provides a jaw clamping device for a forging manipulator, comprising:

[0006] Two positioning posts are provided and are respectively located on the two closing surfaces of the jaws;

[0007] A positioning ring, which is arranged corresponding to the positioning post and sleeved on the corresponding positioning post;

[0008] The clamping angle iron is arranged corresponding to the positioning ring and fixed to the end of the corresponding positioning ring away from the closed surface, and the two clamping angle irons are arranged opposite to each other.

[0009] Optionally, the positioning ring and the clamping angle iron are connected by a weld.

[0010] Optionally, the positioning column is welded and fixed on the corresponding closed surface.

[0011] Optionally, the axial length of the positioning ring is greater than the axial length of the positioning column.

[0012] The forging manipulator provided by the utility model comprises a jaw, wherein the distal end of the jaw is formed with two closed surfaces, and the forging manipulator jaw clamping device is mounted on the two closed surfaces.

[0013] The technical solution provided by the utility model has the following advantages compared with the prior art:

[0014] The forging manipulator jaw clamping device provided by the present invention adds positioning columns to the two closed surfaces of the original forging manipulator jaws. Each positioning column is connected to a positioning ring and an angle iron, so that the jaws can not only have the original clamping function, but also can be clamped by two angle irons, so that the jaws can clamp both molds and forgings, and the scope of use is effectively widened. At the same time, the shape of the angle iron is more conducive to the clamping of rectangular forgings and shaft rod forgings, which can avoid surface damage to rectangular forgings due to the small clamping area, and can also increase the clamping area of ​​shaft rod forgings to maintain their stable clamping. In addition, the device is easy to install and disassemble on the original forging manipulator and does not destroy the basic functions of the original forging manipulator, and has strong promotion potential.
