Embodiment Construction
[0010] A stamping die forging, including a forging 1, an insert 2 and a steel block 3, the insert 2 and the steel block 3 are embedded in the forging 1, the insert 2 is arranged on the upper part of the steel block 3, and the steel block 3 The surface is on the same plane as the surface of the forging 1, the surface of the insert 2 slightly protrudes from the surface of the forging 1, and the surface of the insert 2 slightly protrudes from the surface of the steel block 3. When the steel block 3 in the forging 1 is locally damaged during the stamping process of the present invention, the insert 2 is wire-cut to an ideal size, which is convenient for maintenance.

The invention relates to a stamping die forge piece comprising a forge piece, an insert and a steel block. The insert and the steel block are embedded in the forge piece. The insert is arranged on the upper portion of the steel block. The surface of the steel block and the surface of the forge piece are on the same plane. The surface of the insert is protruded out of the surface of the forge piece slightly, and the surface of the insert is protruded out of the surface of the steel block slightly. The stamping die forge piece has the advantages that a die edge produced with the method is simple in structure and maintenance, easy to manufacture and low in cost, a large amount of production time is saved, a lot of materials are saved and manufacturing cost is reduced.
Description
technical field [0001] The invention relates to a trimming die for an automobile cover part, in particular to a stamping die forging. Background technique [0002] With the rapid development of the automobile industry, the processing and manufacturing of large panel dies is becoming more and more common. Because the size of this type of mold is relatively large and the structure is relatively complicated, especially the trimming mold, the shape of the cutting edge is very irregular, and it is limited by the shape and size of the workpiece. When the forging trimming edge is damaged and repaired, two methods are generally used: repair welding and insert replacement. [0003] When the repair welding method is used, there is a risk of cracking in the damaged area, and the edge strength of the repair welding edge is not high, and the repair welding edge often falls off during the stamping process, which reduces production efficiency. [0004] When the method of changing...
