Three-roller linkage adjustable CNC four-roller plate rolling machine

Abstract

Disclosed is a numerically controlled four-roller plate rolling machine with three linked and adjustable rollers, the plate rolling machine comprising: a base (4), two supports (1) positioned on the base (4), and an upper roller (21), a lower roller (22), a first side roller (23) and a second side roller (24) positioned between the two supports (1). The upper roller (21), the lower roller (22), the first side roller (23) and the second side roller (24) are arranged parallel to each other; the lower roller (22) is located directly below the upper roller (21); and the first side roller (23) and the second side roller (24) are located on two sides of the lower roller (22) respectively, wherein the upper roller (21) is mounted on the supports (1) and rotatably connected to the supports (1). The upper roller (21) is driven to rotate by a servo drive device for the upper roller. Two ends of the lower roller (22), the first side roller (23) and the second side roller (24) are mounted respectively to side roller linkage mechanisms (3) on two sides; the relative positions of the three rollers are invariant; and the side roller linkage mechanisms (3) on two sides are respectively connected to the supports (1) and the base (4) via lifting mechanisms (5). The numerically controlled four-roller plate rolling machine with three linked and adjustable rollers is stable in operation, favourably controllable in precise positioning, efficient and highly automated in numerical control, and can easily achieve the rolling of thin-walled cylinder workpieces having a special shape such as an elliptical or square shape, and the shaped product is of high precision and good quality.

Description

technical field [0001] The invention relates to the field of plate rolling machines, in particular to a three-roller linkage adjustable numerical control four-roller plate rolling machine with high precision and good quality of metal plate forming products, and easy to realize the rolling of oval, square and other special-shaped thin-walled cylindrical workpieces . Background technique [0002] With the rapid development of national defense and civilian industries, the market demand for various circular cylinder parts is increasing. The four-roller plate rolling machine is more and more favored and affirmed by users for its high rolling precision, fast efficiency, and small plate end straight edge. The traditional four-roll plate rolling machine can be divided into linear and arc type four-roll plate rolling machines according to the different ways of lifting the side rolls. [0003] For example, Chinese patent CN204108046U discloses a four-roller plate bending machine wit...

AI Technical Summary

Problems solved by technology

[0006] 1. The motion accuracy and precise positioning of the side roller lifting are relatively poor;

[0007] 2. During the rolling process of the cylinder, it is necessary to continuously switch the action of the work roll, and the operation is relatively cumbersome and slow
