Continuous mold bending and fixing device

Abstract

The invention discloses a continuous mold bending and fixing device. The device comprises a concave mold body, wherein first grooves which are symmetrically arranged are formed in the two sides of thetop end of the concave mold body; a sliding block is connected to the side walls of the two sides of each first groove in a sliding mode, sliding plates are welded between the sliding blocks, and a supporting plate is welded between the sliding plates; a second groove is formed in the top end of the supporting plate, the side wall of the bottom end of the second groove is connected to a bearing base, a rotating shaft is connected inside the bearing base, and a rotating plate is welded to one end, away from the bearing base, of the rotating shaft; a wire winding disc is welded outside the rotating shaft, and the wire winding disc is connected to an adjusting wire; and the bottom end of the supporting plate is connected to a first spring, a pressing plate is welded to the bottom end of thefirst spring, a first through hole is formed in the side wall of one side of the sliding plate, and limiting plates which are symmetrically arranged are connected to the side walls of the two sides ofthe first through hole in a sliding mode. According to the device, a workpiece can be bent rapidly to carry out fixing, the workpieces with different thicknesses and sizes can be fixed, the deviationamplitude of the workpiece in the bending process is greatly reduced, and the bending precision is improved.

Description

technical field [0001] The invention relates to the technical field of continuous dies, in particular to a bending and fixing device for continuous dies. Background technique [0002] Continuous die (also known as progressive die, skip die) refers to the punching die that completes multiple processes at the same time in several different positions in one stroke of the press. Punching parts are formed step by step in the continuous die, and continuous forming is a process-intensive process method, which can complete various processes such as edge trimming, incision, grooving, punching, plastic deformation, blanking, etc. on a pair of dies. According to the actual needs of stamping parts, multiple stamping processes (called stations in the progressive die) are arranged in a certain order for continuous stamping. It can not only complete the blanking process, but also complete the forming process and even the assembly process. Many complex stamping parts that require multi-pro...

Problems solved by technology

[0003] When the traditional continuous die is used for bending processing, the two ends of the workpiece will shrink when it is bent. The traditional continuous die has no fixing device. The workpiece is placed on the surface of the die, and then it is directly bent at multiple places. During the bending process , the contraction of the workpiece will cause the position of the workpiece to move, causing the bending position to deviate, thereby reducing the bending accuracy. For this reason, we propose a continuous die bending fixture
