Description

Technical Field

[0001] The utility model relates to the technical field of thermal processing, in particular to a thermal processing clamping fixture which is easy to move flexibly. Background Art

[0002] With the development of science and technology and the improvement of production level, there are further requirements for the quality of workpieces, labor productivity, labor conditions and production costs, and hot working has also developed rapidly. Hot working is a plastic processing method in which the metal is heated to a high temperature below the solidus line of the metal phase diagram and above the recrystallization temperature, and a force is applied to make it plastically deformed to achieve the desired shape and size.

[0003] After searching, a Chinese patent with publication number CN215748794U discloses a fixing fixture for metal hot processing. The technical points are: first, the fixing fixture is moved to the work site through the universal wheel, and then the metal object is placed on one side of the clamp, and then the screw is turned by the handle. Then, when the two clamps are in contact with the metal object, the clamp slides through the slider, and the elasticity of the spring plays a better clamping effect. After the clamping and fixing are completed, the hot processing operation is started. When the hot processing operation is completed, the screw is turned by the handle to separate the metal object from the clamp, and then the fixing block is rotated and retracted to the card box, and limited by the limit block.

[0004] However, existing metal hot processing fixing fixtures generally use universal wheels to reduce friction with the ground to facilitate movement, but the rotation angle of the universal wheels cannot be fixed, which requires a large force to maintain the stability of the device when turning, increases the labor intensity of the staff, and makes the device less flexible. Therefore, a new solution is needed to solve this problem. Utility Model Content
