[0002] In the metal forging process, the clamping of the workpiece is a key link to ensure the forging quality and improve production efficiency. However, the existing clamping devices for metal forging generally have the following problems: the clamping force is uneven, which easily leads to deformation of the workpiece; the clamping force is difficult to adjust and cannot adapt to workpieces of different sizes and shapes; friction heat is easily generated during the clamping process, which affects the quality of the workpiece. Therefore, it is necessary to design a new type of clamping device for metal forging to solve the above problems.

[0003] The prior art discloses a pneumatic clamping metal forging fixture with a publication number of CN210632875U, including an air column, an air pressure cylinder is arranged at the upper end of the air column, an air pressure spring is arranged on the inner wall of the side of the air pressure cylinder, a pressure relief valve is arranged on the upper part of the air pressure cylinder, a fixture frame is arranged on the air pressure cylinder, fixture arms are arranged on both sides of the fixture frame, an air pressure baffle is arranged at the bottom end of the fixture arm, and the gap between the air pressure baffles forms an air pressure chamber, a fixture head is arranged at the top of the fixture arm, a fixture mold is arranged on the fixture head, and a connecting port is arranged on the front and back of the air pressure cylinder. In this application, through the coordinated use of the pressure relief valve, the air pressure chamber, the connecting port, the connecting hole, the fixture mold, and the fixture head, the force of the fixture will be released when the force applied by the fixture reaches the bearing limit of the object, so as to achieve the effect of protecting the clamped object, and the fixture can be connected to the connecting port of another fixture through the connecting port by bolts, and the fixture mold can be replaced for objects with complex shapes, which is more convenient to use and has a wider range of application.
