Description

Technical Field

[0001] The utility model belongs to the technical field of forging clamps, in particular to a forging clamp used for forging workpieces. Background Art

[0002] Forging is divided into free forging and die forging. Generally, large cylindrical forgings can be obtained by die forging. The process of die forging is to put the heated blank into the forging workpiece die, and then repeatedly hit the blank with a die forging hammer to forge the shape of the blank to the same shape as the forging die. The blank is also called a forged workpiece after forging. It is a processing method to make it plastically deformed to obtain forgings with certain mechanical properties, certain shape and size.

[0003] During the forging process, it is often necessary to use the grippers on the robot to clamp the forged workpiece and move it to a specified position.

[0004] At present, the clamping mechanism clamps the forged workpiece by two clamping jaws. During this process, the high-temperature forged workpiece will contact the main structure of the clamp in addition to the clamping jaw. The high temperature of the forged workpiece will cause the temperature of its internal structure to rise. Long-term exposure to high temperature erosion will affect its service life to a certain extent. Secondly, the friction force required for clamping is completely achieved by the clamping jaw, which makes the clamping effect limited.

[0005] Therefore, it is very necessary to invent a forging clamping jaw for forging a workpiece. Utility Model Content

The driving rack is slidably installed in the clamping jaw transmission base. The driving hydraulic cylinder is fixedly installed on the outside of the clamping jaw transmission base. The output end of the driving hydraulic cylinder is fixedly connected to one end of the driving rack. The other end of the driving rack is provided with a sliding chamber. The telescopic slide rod is slidably installed in the sliding chamber, and the telescopic slide rod is fixedly connected to the spring installed inside the telescopic slide rod. The thrust temperature insulation platform is fixedly installed on one end of the telescopic slide rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model mainly adopts a rack transmission mechanism and a gear transmission mechanism to clamp the forged part. The ingenious design of the rack mechanism and the gear structure can drive the two clamping jaws to clamp the forged part, and the rack can also generate an independent external driving force. The thrust will also be applied to the forged part, thereby increasing the friction between the clamping jaws and the forged part.
