Automated 2 Roll Plate Bending Machine For Gas Cylinder Production

The gas cylinder production equipment refers to the equipment line for producing the gas storage cylinder. The production equipment mainly includes: two-roll bending machine, circumferential seam welding equipment, straight seam welding equipment, rotary gun welding machine, group-to-machine, etc.

Introduction of 2 Roll Plate Bending Machine:
The 2 Roll Plate Bending Machine is mainly used for rolling cylindrical workpieces, carbon steel plate 0.3-4.0MM, stainless steel 0.3-2.5MM. Advantages: The winding is quick, one-time forming, precise without leaving straight edges, and the rounded workpiece is rounded to ensure that it is within 0.5MM.

It is used for rolling all kinds of metal sheets (iron plate, aluminum plate, stainless steel plate) into a round barrel with a thickness of up to 3.5mm. The rolled parts are round and accurate. The equipment is controlled by PLC, convenient in operation, reliable in accuracy and high in efficiency. It can be widely used in motorcycles, automobile manufacturing, electromechanical, solar energy and other fields. The equipment can be selected from automatic feeding and manual feeding.
The working principle and safe operation rules of the two-roller bending machine:

The upper roller of the coiling machine acts on the piston for vertical lifting movement through the hydraulic oil in the hydraulic cylinder in the central symmetric position of the two lower rollers. The final gear of the main reducer drives the two lower roller gears to engage in rotary motion to provide torque for the rolled plate. . The flat plastic sheet of the coiling machine passes through the three working rolls (two lower rolls and one upper roll) of the equipment, and the metal plate is continuously bent in multiple passes by the lower pressing of the upper roll and the rotating motion of the lower roll. , producing permanent plastic deformation, rolling into the desired cylinder, cone or part of them.

The two-roller bending machine is a two-roller roll-type bending device. It is mainly used for bending the sheet thickness of 0.5-6mm, width 300mm-2000mm in the process of cold use, and the metal plate cylinder cylinder with the yield limit below 350Mpa. Widely used in the production of various cylindrical cylinders in the automotive, food machinery, electrical machinery, fire-fighting equipment and other industries.
Features: The two rolls have the characteristics of high precision, no straight edge and high production efficiency. The highest garden accuracy error is less than 0.5mm; the highest efficiency is up to 400/hour.
Working principle: The steel plate is pressed by the upper roller between the upper roller (two rollers) lower roller (elastic roller), and the elastic layer of the lower roller is concavely shaped to cause the steel plate to bend, so that the curvature is formed.
According to different structural forms and control methods, the ability and efficiency of the machine are determined.
Analysis of the winding process of two-roll bending machine

The three rolls must be completed by four processes of pre-bending, centering, winding, and rounding, and the hydraulic automatic two-roller-rolling machine completely changes the three-roller winding method, eliminating the above process and forming at one time. The upper roller of the two-roller device is a rigid roller, and the lower roller is a flexible roller. When the lower roller is pressed by the upper roller, there is a certain radial concave deformation, and when the steel plate is fed between the upper roller and the lower roller, it is The two rolls are rolled into a cylinder. From a microscopic point of view, the rolled cylinder is actually composed of numerous small arcs.

Structural design of two-roller bending machine

The two-roller numerical control hydraulic coiling machine has two upper and lower rollers, wherein the lower roller is a flexible roller, which is a driving roller, which is driven by a motor through a speed reducer and a coupling thereof, and is driven by a hydraulic unit to vertically rise and fall, and the upper stick is The rigid roller, which is a driven roller, is fixedly mounted on the machine bed. When the lower roller is raised to contact with the upper roller, the upper roller will rotate with the lower roller, and the plastic metal plate passes between the upper roller and the lower roller of the machine. The metal plate is rolled into the desired cylinder. After the winding process is completed, the lower roller hydraulic pressure is lowered, and the roll locking head is opened to take out the product.
