Plate rolling and bending machine

Abstract

The invention provides a plate rolling and bending machine. The plate rolling and bending machine comprises two supporting walls which are oppositely arranged, a plurality of adjustment screws, two rows of forming roller sets arranged on the two supporting walls correspondingly, and a conveying mechanism located between the two rows of forming roller sets. Each supporting arm comprises a supporting plate and a plurality of sliding blocks, wherein a plurality of sliding grooves are formed in the supporting plate at intervals, and each sliding block is slidably arranged in the corresponding sliding groove. Each adjustment screw is connected to the corresponding supporting plate in a screwed mode and connected with the corresponding sliding block. At least one side of each sliding groove is provided with a scaleplate. Each row of forming roller sets includes a plurality of sets of forming rollers which are arranged at intervals in the plate conveying direction. Each forming roller set includes an upper roller and a lower roller which are oppositely arranged, wherein one end of the upper roller is rotatably connected to the corresponding sliding block, and the lower roller is rotatably installed on the corresponding supporting plate. According to the plate rolling and bending machine, the vertical positions of the sliding blocks and the upper rollers are measured through the scaleplates, so that the consistency of the adjustment quantity of the upper rollers on the same supporting wall is guaranteed, and the plate bending precision is improved accordingly.

Description

【Technical field】 [0001] The invention relates to the technical field of metal forming, in particular to a plate rolling bending machine. 【Background technique】 [0002] Sheet metal roll bending machine is a device for bending sheet metal, which includes two support plates and multi-component forming rollers that rotate on the two support plates. Each set of forming rollers includes an upper roller and a lower roller that are set opposite to each other. The upper roller and the lower roller are provided with a cooperating bending surface for bending the plate passing between the upper roller and the lower roller. Each upper roller is connected to the support plate through a screw, and the distance between the upper roller and the lower roller is adjusted by extending or retracting the screw to adapt to the bending operation of plates with different thicknesses. However, in the sheet material rolling bending machine of the prior art, the extending or retreating distance of t...

AI Technical Summary

Problems solved by technology

However, in the sheet material rolling bending machine of the prior art, the extending or retreating distance of the screw is not easy to control, and it is easy to cause the distance between the upper roller and the lower roller of each set of forming rollers to be unequal, thereby affecting the bending of the sheet metal.
