Description

Clamp and tool

Technical Field

The utility model belongs to the technical field of clamps, and particularly relates to a clamp and a tool.

Background

The metal sheet forming limit diagram reflects the local forming limit of the material under the unidirectional or bidirectional stretching effect, is generally used for judging the local forming performance of the material, and is widely applied to sheet forming prediction and simulation analysis. Before large-scale stamping forming of the metal plate, small-batch test production is usually required, at this time, strain of the metal plate needs to be tested, and the thinning rate of the plate in the forming process is obtained to judge the matching degree among structural design, materials and dies, so that basis is provided for the next optimization and large-scale production. Whether the forming limit diagram test or the small-batch trial strain test of the parts is carried out, marking patterns are printed on the surface of the metal plate before the test, and the strain of the material is obtained through the deformation of the marking patterns. The quality of the mark pattern printing directly influences the accuracy of the subsequent strain test result.

A grid template for a common sheet metal marking machine is shown in fig. 1, and a frame and the grid template are integrated. When the mark is printed, the grid template is directly attached to the metal plate through an operator, the attaching position and the compactness depend on the operation force of the operator, and phenomena such as loosening and sliding often occur, so that the quality and the printing efficiency of the mark pattern are affected. The plate and the marking head are respectively arranged at two ends of the electrode, the plate is connected with the marking machine through a power line, a connecting line of the plate is always in contact with the grid template, and friction with the grid template is caused in the processes of loosening, sliding and the like, so that the grid template is damaged, the quality of the grid is influenced, and the service life of the device is shortened. These will affect the quality of the grid and thus the subsequent strain testing, leading to larger errors in the results or failure of the test.
