Problems solved by technology

Unfortunately, during the forming process of the curved surface of the sheet metal, the blank holder device mainly passively restricts the flow of the sheet metal, and the blank holder force in the device is unevenly distributed between the blank holder ring and the sheet material; resulting in uneven flow of metal , prone to defects such as wrinkling, excessive wall thickness reduction and cracking, which affect the performance and quality of sheet metal forming

Embodiment Construction

[0029] In order to suppress defects such as wrinkling and cracking of the sheet metal caused during the forming process of the curved surface of the sheet metal, the present invention is realized through the following technical solutions: the flexible edge pulling device for sheet metal forming of the present invention mainly consists of a plurality of clamping mechanisms 1 , a plurality of pulling mechanisms 2 and a support frame 3; a plurality of clamping mechanisms 1 are clamped around the sheet 4 to be processed, and a plurality of pulling mechanisms 2 apply edge pulling forces in different directions of the sheet 4. The size of the pulling edge force is adjustable, and its value is determined by the size and shape of the formed part. The pulling mechanism 2 is composed of hydraulic cylinders arranged in the horizontal direction. The piston end of each hydraulic cylinder is connected with the clamping mechanism 1, and the cylinder end is hinged with the support frame 3; one...

Abstract

The invention discloses a flexible side drawing device for forming panel veneer, relates to plastic processing equipment for forming a curved surface of a plate like piece, and belongs to the field of mechanical engineering. The device mainly comprises a plurality of material clamping mechanisms (1), a plurality of material drawing mechanisms (2) and a supporting frame (3); and the plurality of the material clamping mechanisms (1) clamp the periphery of plate veneer (4) to be processed and the plurality of the material drawing mechanisms (2) apply side drawing force in different directions of the plate veneer (4). The device can be matched with various stamping dies with different sizes and shapes, so that the design and manufacturing cost of the module for forming the plate like part are saved, and disadvantages of corrugation, pull cracks and the like caused when the plate like part is formed are inhibited.

Description

technical field [0001] The invention discloses a flexible edge pulling device for sheet metal forming, relates to plastic processing equipment for forming curved surfaces of sheet metal parts, and belongs to the field of mechanical engineering. Background technique [0002] Sheet metal forming is one of the important manufacturing techniques in modern industry. As the shape of stamping parts becomes more and more complex, in order to improve the forming performance of parts and eliminate defects such as wrinkling and cracking of parts during the sheet metal surface forming process, a blank holder is usually installed in the sheet metal surface forming mold. The design of blank-holding device and the control of blank-holding force are important contents of die design for sheet metal forming. Unfortunately, during the forming process of the curved surface of the sheet metal, the blank holder device mainly passively restricts the flow of the sheet metal, and the blank holder f...
