A plate rolling machine is a shaping machine for continuous point bending of plates. It has the function of rolling O-shaped, U-shaped, multi-segment R, and other shapes of plates.
What is the principle of using a roll bending machine?
How many steps are there in the rolling process?
What are the ways to use the a roll bending machine?
Cylinder and cone a roll bending machine can be regarded as the generatrix of the cylindrical and cone a roll bending machines rotated 360 degrees around the center of rotation in the same plane. The generatrix of the cylindrical a roll bending machine is parallel to the center of rotation, and the generatrix of the cone a roll bending machine is parallel to the center of rotation. The line is slanted.
1. First, feed the a roll bending machine into the work roll of the roll bending machine. One roll is above the a roll bending machine, called the upper roll, and two are below the a roll bending machine, called the bottom roll. This is a three-roller; four-roller The plate bending machine has three rollers under the a roll bending machine, one is in the same vertical surface of the upper roller, called the middle and lower rollers, and the other two are on both sides of the upper roller, called side rollers. The upper roller can be combined with the side rollers. Any two of the middle and lower rollers bend the a roll bending machine. This article only discusses the symmetrical arrangement of the two lower rollers or the side rollers and the upper roller;
2. The second step is the feed motion of the work roll, that is, three-point bending. Some plate rolling machines use the upper roll for pressing and feeding, and some have the lower roll or side roll for upward feeding. For the convenience of description, According to the principle of relative motion, the a roll bending machine and the lower roller or side roller are regarded as stationary, and the upper roller is pressed down; when the upper roller of the cylindrical a roll bending machine is pressed down, it is parallel to the lower roller, and the upper roller of the cone-shaped workpiece is pressed down When the time is tilted with the lower roller; the more the amount of reduction, the greater the curvature of the generatrix and the vicinity of the contact between the a roll bending machine and the upper roller;
3. The third step is to rotate the a roll bending machinee through the rotary motion of the work roll while ensuring that the pressing amount of the upper roll remains unchanged, so that each generatrix of the a roll bending machine has the same curvature or curvature distribution, and becomes a cylinder and a cone.
When the a roll bending machine rolls the plate, in terms of the geometric position of the plate head and tail on the machine, the plate head and the plate tail will not be a circle. Take the symmetrical three rollers as an example. The shape of the steel plate changes from a straight line (very short)-arc to arc-arc. Although the position of the three rollers has not changed during this process, the deformation of the steel plate has changed, so the rolled arc Not a curvature.
The a roll bending machinee has been widely used in machinery production, product packaging, and other industries. ChaoLi Company, as a Chinese pioneer in rolling and bending machines, can ensure the products’ quality and the after-sales service.
