Bending die and bending method thereof

Abstract

The invention discloses a bending die and a bending method thereof, and belongs to the field of numerical control punching die metal plates. The bending die comprises an upper die part and a lower diepart, and the upper die part comprises an upper die knife edge. The lower die part comprises a rolling shaft knife edge, a rocker arm, a rolling shaft knife edge fixing seat, a sliding block and a lower die seat, the rolling shaft knife edge is rotatably connected to the rolling shaft knife edge fixing seat, the rocker arm penetrates through the rolling shaft knife edge fixing seat and is used for fixedly connecting the rolling shaft knife edge with the sliding block, the sliding block is slidably connected in the lower die seat, the sliding block slides and meanwhile drives the rolling shaftknife edge to rotate, a bending groove is formed in the rolling shaft knife edge, during die assembly, the upper die knife edge presses a workpiece into the bending groove, and meanwhile the rollingshaft knife edge rotates to bend the workpiece. The bending method is a using method based on the bending die. The bending die can be used for machining a protruding bending structure on a sheet metalpart, and is suitable for machining of small sizes and multiple bending angles.

Description

technical field [0001] The invention belongs to the field of numerical control stamping die sheet metal, and more specifically relates to a bending die and a bending method thereof. Background technique [0002] With the development of the world economy, automobiles, electrical appliances, ships, etc. need parts with different bending shapes to meet their assembly requirements. For locally convex and multi-bending sheet metal parts, welding is generally used to weld the bent convex parts to the sheet metal body to achieve a locally convex bending structure, but the welded structure The overall structural strength is not as good as the bending workpiece. In order to reduce the number of welds and improve the structural strength of the workpiece, the bent workpiece can be used instead of the welded workpiece, which can not only improve the protective performance of the workpiece during use, but also make the workpiece more beautiful. However, most of the existing bending die...
