Sliding block structure and device for bending

Abstract

The invention discloses a sliding block structure for bending, which comprises a fixed plate, first sliding blocks and second sliding blocks, wherein first inclined surfaces are arranged on the two sides of the fixed plate, and an included angle between the first inclined surfaces and the top surface of the fixed plate is an acute angle; the first sliding blocks are arranged on the two sides of the fixed plate, each first sliding block is provided with a first sliding surface connected to the corresponding first inclined surface in a sliding mode, the sliding direction of each first sliding block has a component facing the fixed plate, and the side surface of the end part of each first sliding block is provided with a second inclined surface; an included angle between the second inclined surface and the top surface of the first sliding block is an acute angle; the second sliding blocks are arranged at the end parts of the first sliding blocks, each second sliding block is provided with a second sliding surface which is in sliding joint to the second inclined surface, and the sliding direction of the second sliding block has a component towards the first sliding block. The invention further provides a corresponding device. Mold bending and demolding in two directions are achieved, so that the problem that mold production cost is increased due to bending deformation during bending can be effectively solved.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a slider structure and device for bending. Background technique [0002] Most of the server chassis structural parts currently used in the market have U-shaped bases, and U-shaped base structures are widely used in server chassis structural parts. However, in the design of its U-shaped bending mold device, because the current common bending mold slider can only move in one direction, and the mold must be demoulded, if there is an adjacent bending edge facing the U-shaped inner side, it cannot be demoulded. It will cause empty folds or structural deformation, resulting in poor appearance, or a new station for adjacent bending needs to be added, which requires an additional set of molds, which increases the manufacturing cost. Contents of the invention [0003] In view of this, in order to overcome at least one aspect of the above problems, an embodiment of the present inventi...
