Embodiment Construction

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to traceless bending equipment. The equipment comprises an upper die and a lower die which are used for bending a metal plate; the upper die comprises an upper die plate, a sliding block seat and sliding blocks, the sliding block seat is fixed below the upper die plate in an up-down movable mode, the sliding blocks are arranged on the two transverse sides of the sliding block seat, bending punches are formed on the two transverse sides of each sliding block, and the sliding block seat moves up and down to drive the sliding blocks to move in the transverse direction; and the lower die comprises a base, a lower die plate fixed to the base, a precursor block arranged on the lower die plate and capable of moving up and down, a forming block arranged on the transverse outer side of the precursor block, a baffle fixed to the lower die plate and located on the transverse outer side of the forming block, and an elastic piece of which one end abuts against the baffle and which provides transverse elastic force for the forming block, a matching inclined surface is arranged on the transverse outer side of the precursor block, and the forming block is provided with a forming inclined surface corresponding to the matching inclined surface. Traceless bending can be achieved, and springback after bending is avoided.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a traceless bending device. Background technique [0002] Existing bending dies for sheet metal generally include an upper die and a lower die. The lower die includes a fixed forming block on one lateral side, and a pressing block that is placed inside the forming block and can move up and down. The upper mold includes a bending punch, and the bending punch and the pressing block jointly clamp and fix the metal sheet, and at the same time, the bending end of the metal sheet is located on the upper surface of the fixed forming block, and the bending punch The downward movement of the head drives the metal plate and the pressing block to move downward, and the metal plate is bent through the extrusion between the bending punch and the forming block. The bending scheme will pre-clamp the metal sheet, and a hard bend will occur between the bent end of the metal sheet and the forming ...
