Bending mechanism

Abstract

The invention discloses a bending mechanism. The bending mechanism comprises an installation frame, a clamping structure, a transmission structure, a bending block and a power device, wherein the clamping structure is arranged on the installation frame and used for clamping a part to be bent; the transmission structure is arranged on the installation frame; the bending block is installed on the transmission structure; the power device is used for enabling the bending block to press downwards and bend the part to be bent by driving the transmission structure to work; one end of the bending block is hinged to the transmission structure; a bending downward pressing surface is formed at the other end of the bending block; when the bending downward pressing surface is in an initial non-bent state, the bending downward pressing surface is located above the part to be bent and is close to the part to bent in parallel; the transmission structure drives the bending block to rotate around a point by a preset angle, and the point is a bending rotary point of the bending position of the part to be bent; in the rotation process of the bending block, the bending downward pressing surface tightly presses the part to be bent all the time. According to the bending mechanism, the relative friction between the bending block and the part to be bent is reduced, and therefore abrasion to the part to be bent in the bending process is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic component processing equipment, in particular to a bending mechanism. Background technique [0002] The bending mechanism is a commonly used mechanism in the mechanical field, which can bend a variety of materials. Taking the PIN pin as an example, some existing electronic components usually need to be equipped with a bent PIN pin inside. Bending the PIN pin often requires Realized by bending mechanism. [0003] Chinese patent document CN203900340U discloses a shear bending mechanism, including a support plate, a bottom plate, a carrier locking device, a product carrier, a lower die, a vertical plate, a cylinder fixing plate, a cylinder, a lifting plate, a guide column, an upper Die cutter, connecting column, pressing block and electronic products; there are two support plates, and base plates are installed on the two support plates, the carrier locking device is installed on the lower part of...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the relative friction between the bending mechanism and the bent piece in the prior art is relatively large during the bending process and cause wear to the bent piece, thereby providing a The bending mechanism that reduces the wear and tear on the bent piece due to the small relative friction between the bent piece and the bent piece during the bending process

[0006] Another technical problem to be solved by the present invention is to overcome the defect of the bending mechanism in the prior art that the bending angle of the bent piece is relatively small, so as to provide a bending mechanism with a large bending angle for the bent piece
