Flexible bending center pressing cutter mechanism

Abstract

The invention relates to the field of bending equipment, in particular to a flexible bending center pressing cutter mechanism. The flexible bending center pressing cutter mechanism comprises a linearguide rail, a guide rail sliding block, a sliding block base plate and pressing cutters which are sequentially connected in the longitudinal direction, the pressing cutters comprise pressing cutter upper parts and pressing cutter main bodies, the linear guide rail is fixedly connected with a positioning wallboard, one end, away from the positioning wallboard, of the sliding block base plate is fixedly connected with a limiting air cylinder block, a limiting air cylinder is installed on the limiting air cylinder block, an air cylinder jacking column of the limiting air cylinder stretches out and abuts against the positioning wallboard; and step-shaped clamping tables are arranged between every two adjacent pressing cutter main bodies. According to the flexible bending center pressing cuttermechanism, the linear sliding rail and the sliding block are adopted, so that the friction resistance is reduced, and meanwhile, the abrasion degree of the pressing cutters is reduced; automaticallylocking the pressing cutters is carried out by adopting the positioning air cylinder, the positioning accuracy and stability of the pressing cutters are guaranteed, and therefore the bending accuracyis improved; mutually stacked step-shaped clamping tables are arranged between the adjacent pressing cutters, so that the pressing cutter deflection caused by non-uniform stress of the pressing cutters at the edge of a plate is avoided; and a split type design structure is adopted, so that overall replacement of the pressing cutters is avoided, and the replacement cost is reduced.

Description

technical field [0001] The invention relates to the field of bending equipment, in particular to a flexible bending center knife pressing mechanism. Background technique [0002] At present, the flexible bending center feeding methods on the market are mainly divided into two types. One is to use a small linear guide rail as a guide, directly slide and install the press knife on the linear guide rail, and use the press plate structure to press the press knife, and the press knife is close to There is a large chamfer at the front end of the feeding material to realize the assembly of the press knife mechanism. This structure completely relies on the press plate to limit the displacement of the press knife, and the press plate is only fixed by a bolt. In high-strength use, the press plate is easy to loosen, making the press knife Shaking occurs when the plate is bent, which affects the bending accuracy of the plate. At the same time, because the pressure knife bears the pressu...
