Description

technical field

[0001] The invention relates to a tool, in particular to a double-layer punching tool for controlling a valve cover. Background technique

[0002] At present, some small casting processing factories use scribe positioning to punch holes one by one when punching some workpieces. This not only has large shape and position tolerances, but also has cumbersome procedures and high labor intensity, making it difficult to achieve mass production. Contents of the invention

[0003] In view of the problem of large tolerances in the positioning of workpiece punching and marking lines, the technical problem to be solved by the present invention is to provide a double-layer punching tool for controlling the valve cover. The utility model has the advantages of simple structure, precise positioning and strong practicability, and greatly improves production efficiency.

[0004] In order to achieve the above object, the technical scheme that the present invention take...
