A self-positioning strip-material integrated inner and outer corner chamfering device

Abstract

The invention discloses a self-positioning strip integral interior and exterior angle chamfering device. The device is characterized by comprising an upper die assembly and a lower die assembly; the upper die assembly includes an upper die frame, an upper base plate, an upper fixed plate, an upper baffle plate and a pressure plate; the lower die assembly includes a lower die plate, a lower base plate and a lower die frame; a punch penetrates through the upper fixed plate, the upper baffle plate and the pressure plate, and is provided with a necking-down structure; and the necking-down structure is provided with a first arc section and a second arc section. A limiting projection is arranged on the lower die plate; and a limiting groove is formed in the pressure plate. A strip is automatically positioned by the limiting projection on the lower die plate, only needs to be put in the limiting projection when placed, and has no redundant rim charge. In addition, the integral interior and exterior angle chamfering device uses the punch to perform downward pressing, uses the first arc section and the second arc section for respectively realizing chamfering of an exterior angle and an interior angle, and has no need of two times of chamfering compared with a traditional structure.

Description

technical field [0001] The invention relates to a strip material chamfering device, in particular to a self-positioning strip material integrated internal and external corner chamfering device. Background technique [0002] The traditional chamfering of strips is mostly manual or mechanical chamfering. Manual chamfering is rare due to low work efficiency and difficult to grasp. Mechanical chamfering often uses chamfering devices to directly chamfer strips. However, currently In some chamfering devices, the strips are placed in the chamfering mold, and the chamfering of the corresponding parts is performed by manually adjusting the position of the strips, or the size of the strips is larger than the actual required workpiece size, and then the excess edge is cut by the chamfering device. In addition, traditional chamfering devices can only perform single chamfering of outer corners or inner corners. It is necessary to perform precise chamfering without cutting off edge materi...

[0002] The traditional chamfering of strips is mostly manual or mechanical chamfering. Manual chamfering is rare due to low work efficiency and difficult to grasp.

In addition, traditional chamfering devices can only perform single chamfering of outer corners or inner corners. It is necessary to perform precise chamfering without cutting off edge materials.
