Full-automatic four-roller plate rolling machine

Abstract

The invention relates to the technical field of plate rolling machines, in particular to a full-automatic four-roller plate rolling machine. The full-automatic four-roller plate rolling machine comprises a body and a rolling and pressing device assembled on the body, wherein the rolling and pressing device comprises an upper roller, a lower roller, and a front roller and a rear roller which are positioned on two sides of the lower roller respectively; the upper roller comprises a movable end and a fixed end which is in drive connection with a motor; the fixed end is fixed on the body through a bearing; the movable end is provided with a movable shaft seat with opening and closing actions; the movable shaft seat is connected with a shaft seat hydraulic cylinder; two ends of the lower roller, the front roller and the rear roller are connected with a lifting hydraulic cylinder respectively; an automatic feeding device is arranged besides the radial direction of the rolling and pressing device; and an automatic discharging device is arranged besides the axial direction of the rolling and pressing device. The full-automatic four-roller plate rolling machine is provided with a plate rolling control device corresponding to the rolling and pressing device, the automatic feeding device and the automatic discharging device. The plate rolling machine can realize automatic feeding, automatic rolling and automatic discharging and has high production efficiency.

Description

technical field [0001] The invention relates to the technical field of plate bending machines, in particular to a fully automatic four-roller plate rolling machine. Background technique [0002] The plate rolling machine is the main equipment for producing cylindrical or arc-shaped workpieces by passing the plate through the rotating roller shaft, among which the three-roll plate rolling machine and the four-roll plate rolling machine are more commonly used. The working principle of the above-mentioned plate rolling machine is as follows: it consists of an upper roller located above and two or three passive rollers located below the upper roller that can move up and down. The upper roller is driven by a motor and driven by it to rotate, and the passive roller Generally, the lift is driven by the lifting hydraulic cylinder, and the gap between the upper roller and the passive roller is adjusted through the lifting and lowering action of the lifting hydraulic cylinder. In the...

AI Technical Summary

Problems solved by technology

[0003] In the process of rolling cylindrical or arc-shaped workpieces, the above-mentioned plate rolling machines have many defects. For example, manual feeding is generally used, that is, manual feeding and adjustment of the position of the sheet material. This manual method is often due to The deviation of the feeding angle causes the scrapping of the workpiece, low production efficiency and high cost; in addition, the rolled and formed sheet is generally discharged manually, that is, the rolled and formed sheet is manually discharged from the upper roller For large workpieces, it is generally necessary to use lifting tools to smoothly discharge the material, which is labor-intensive and low in production efficiency.
