Upper bracket device for preventing cylinder body from rolling deformation

Abstract

The invention discloses an upper bracket device for preventing a cylinder body from rolling deformation. The upper bracket device comprises a bracket device support body. A roller support A and a roller support C are symmetrically arranged on the upper side of a base of the bracket device support body. A roller support B is arranged on the inner side of the roller support A. An upper roller and alower roller are arranged on the roller support A, the roller support C and the roller support B. The two ends of the upper roller and the two ends of the lower roller are arranged on the roller support A, the roller support C and the roller support B. The rollers are driven by a motor. A stand column is arranged on the top of the roller support C. A transmission rod is arranged at the center in the stand column. A hydraulic oil cylinder is arranged at the bottom end of the transmission rod. A bracket close to the top and on one side of the stand column is driven by the hydraulic oil cylinderto rise or fall. The upper bracket device is reasonable in design, the rolled cylinder body is supported by the bracket when the cylinder body is rolled, and the cylinder body is prevented from deformation.

Description

technical field [0001] The invention relates to the technical field of an upper bracket for preventing rolling deformation of a cylindrical body, in particular to an upper bracket device for preventing rolling deformation of a cylindrical body. Background technique [0002] The plate rolling machine is a kind of equipment that uses work rolls to bend and form the sheet metal. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the plate rolling machine is to move the work roll through the action of hydraulic pressure, mechanical force and other external forces, so that the plate is bent or rolled into shape. According to the rotation movement and position changes of the work rolls of different shapes, oval parts, arc parts, cylindrical parts and other parts can be processed. [0003] In the 1960s, my country began to develop plate rolling machines. The earliest plate rolling...

Problems solved by technology

By the 1970s, some enterprises had achieved initial results in the development of plate rolling machines. For example, Changye Forging Machine Tool Factory successfully developed a four-roller plate rolling machine, which can directly pre-bend the end of the plate. However, the structure is huge and the production cycle long
