Trimming die

Abstract

The invention discloses a trimming die which comprises a lower convex die body, an upper concave die body and a material pressing plate, wherein a sliding assembly is arranged on the lower convex die body, and comprises a sliding seat, a wedge moving part and a wedge driving part; the wedge driving part is used for driving a wedge moving part to move; the wedge moving part is positioned at one end surface of the sliding seat, performs displacement along the end surface arrangement direction of the sliding seat, and comprises a wedge driving surface and a mounting surface; a cutter block is arranged on the side, facing an outward convex forming part, of the mounting surface, and fixed on the mounting surface; a displacement zone is arranged at the position, corresponding to the sliding assembly, of the outer edge of the outward convex forming part; through the displacement zone, the cutter block enters the outward convex forming part; when moving to the displacement zone along with the wedge moving part, the cutter block is propped against the outward convex forming part; and an extrusion block used for driving the wedge driving part to move is arranged on an upper die seat. In order to overcome defects in the prior art, the trimming die is provided; an edge trimming function is achieved in a stamping manner; and the efficiency is improved.

Description

technical field [0001] The invention relates to a mold for producing auto parts, more specifically a trimming mold. Background technique [0002] With the rapid development of the modern automobile industry, the technology of sheet metal covering parts on the surface of automobiles has also developed. In the existing technology, the processing of sheet metal covering parts on the surface of automobiles mainly includes blanking, drawing, punching and trimming, and flanging. , Shaping and other processes are completed. For processes such as drawing, punching and trimming, and flanging, the functions can be integrated into the trimming die and formed by stamping at one time. [0003] The trimming die mainly includes an upper die and a lower punch that cooperate with each other, and a pressure plate is also arranged in the upper die, and different upper dies and lower punches are designed according to the shape of different sheet metal covers. The shape of the trimming die is n...

Problems solved by technology

[0003] The trimming die mainly includes an upper die and a lower punch that cooperate with each other, and a pressure plate is also arranged in the upper die, and different upper dies and lower punches are designed according to the shape of different sheet metal covers. The shape of the trimming die is not the same according to different processes. Usually, in the drawing process, the structure of the trimming die is the simplest, which is used to complete the preliminary forming of the plate, and then trim the edge in the second step. In the process, the edge trimming die will increase the edge trimming function accordingly. For edge trimming, there will be two corresponding situations. The first type of edge to be trimmed is laid flat on the upper punch. This edge is relatively It is easy to repair, first use the pressure plate to press the semi-finished product on the upper punch, then the upper die and the lower punch complete the mold clamping and cut the edge to be repaired orthogonally, because this type of edge is flat on the The one on the lower punch can be cut orthogonally. The second type of side to be repaired is attached to the side wall of the lower punch. This kind of side cannot be cut by orthogonal cutting, which is used in the existing technology. It is trimmed by laser cutting, which adds an additional process and needs to be improved
