Bending die of multi-angle V-shaped workpiece

Abstract

The invention discloses a bending die of a multi-angle V-shaped workpiece, which comprises an upper die; the bending die of multi-angle V-shaped workpiece is characterized in that a lower die comprises two upper concave die blocks and two lower concave die blocks, a workpiece propping plate, an elastic cushion, concave die fixing seats and a lower die seat, wherein steps at two sides of the lower part of the reversed T-shaped workpiece propping plate are identical with a step between the inner side surfaces of the upper block and the lower block of the concave dies, so as to ensure that the workpiece propping plate can move up and down; and the elastic cushion is mounted under the workpiece propping plate. When the bending die is used, plates to be processed are arranged on the upper planes of the two upper concave die blocks; an upper die moves downwards; the plate is gradually pushed to downwards move to form through a convex die; after the plate is formed, the upper die moves upwards; the workpiece propping plate moves upwards to prop the formed workpiece out by the effect of elasticity of the elastic cushion; the multi-angle V-shaped workpiece can be punched and formed by adjusting the downward shifting distance of a sliding block of a punch press; and the bending die of the multi-angle V-shaped workpiece has the advantages of good commonality, convenience for operation, and high production efficiency.

Description

technical field [0001] The invention relates to a mechanically processed cold stamping die, in particular to a multi-angle V-shaped bending die. Background technique [0002] At present, when punching V-shaped parts on a punching machine, a special bending die or a combined die is usually used. A special bending die can only bend one or several angles, and the combined die can bend several angles through combination, but To turn over and assemble, the operation is troublesome and the production efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiencies, and provide a kind of versatility strong, easy to operate, the multi-angle V-shaped piece bending mold of high production efficiency. [0004] The object of the present invention is achieved like this: a kind of multi-angle V-shaped piece bending mold comprises the upper mold that is made up of upper mold base, punch cushion block, punch, and it is...
