Lower die of bending machine and auxiliary mechanism of lower die

Abstract

The invention provides a lower die of a bending machine and an auxiliary mechanism of the lower die. The lower die is provided with at least two V-shaped grooves. The auxiliary mechanism is fixed to two sides of one V-shaped groove, and comprises a movable positioning plate, a spring, a lining, a guiding screw, a base and rollers, the guiding screw is perpendicularly connected with the movable positioning plate, the lining is arranged between the guiding screw and the movable positioning plate, the guiding screw penetrates through the spring to press the spring under the movable positioning plate, the bottom of the guiding screw is fixed onto the base, the rollers are disposed on two sides of the top of the other V-shaped groove, and inclined planes of the other V-shaped groove are tangent to or intersected with circumferential surfaces of the rollers. The lower die of the bending machine and the auxiliary mechanism of the lower die have the advantage that during bending, a workpiece is in rolling contact with the lower die or the edge of the workpiece is in linear contact with the lower die, so that folded marks on the surface of the workpiece are prevented.

Description

technical field [0001] The invention relates to a lower mold of a bending machine and its auxiliary mechanism. technical background [0002] Bending machine mold is a tool used to process sheet metal forming. Under the action of bending machine pressure, the shape of the article can be processed by changing the physical state of the formed material. A tool for turning a blank into a workpiece of a specific shape and size. [0003] Different blank parts should be composed of different bending machine molds. The bending machine mold is divided into the upper mold and the lower mold of the bending machine, which are used for sheet metal stamping forming and separation. The lower mold for forming has a v-shaped cavity, and the upper mold for separation has a cutting edge. [0004] In the production and manufacture of many products, it is necessary to bend the aluminum plate. In the original bending die, the bending will cause surface indentation and scratches, which will affe...

Problems solved by technology

[0004] In the production and manufacture of many products, it is necessary to bend the aluminum plate. In the original bending die, the bending will produce surface indentations and scratches, which will affect the appearance of the product and even cause the process performance of the aluminum plate to decline.
