Description

Technical Field

[0001] The utility model relates to the technical field of metal mold processing, in particular to a positioning and clamping device. Background Art

[0002] Die processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Usually, the die consists of two parts: the upper die and the lower die. The steel plate is placed between the upper and lower dies, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the die is obtained or the corresponding waste is removed. The fixed tooling is one of the tools used to clamp and fix the workpiece during the die processing process, which is convenient for the subsequent processing of the workpiece.

[0003] According to a publicly disclosed metal mold processing fixed tooling (publication number: CN 220839882 U), the above application involves the field of metal mold processing technology, including an operating platform, a lifting device is arranged on the upper side of the operating platform, and a tooling body is arranged on the front of the lifting device. When it is necessary to process the other side of the metal mold, the tooling body can be lifted under the drive of the lifting device, and the clamping blocks on both sides are rotatably connected with the corresponding adjusting rods. After the clamping blocks clamp the metal mold, the metal mold can be driven to rotate along the adjusting rod to change the surface. After the surface change is completed, the lifting device drives the tooling body to descend again to make the metal mold fit the operating platform to ensure processing stability.

[0004] However, in actual use, the above-mentioned equipment needs to be further processed after obtaining the initial shape with the metal mold. Since the surface of the initial metal mold may not be very smooth before processing, the surface is uneven when clamping, which may cause the clamping to be unstable. In view of this, we propose a positioning and clamping device. Utility Model Content
