Because of the different fields of use, the types of roll bending machine are also different, so they have a wide range of applications. It is a piece of general-purpose equipment specially used for bending, forming, and correcting sheet metal. The roll bending machine has a wide range of applications in shipbuilding, chemical industry, boilers, water and electricity, pressure vessels, and machinery manufacturing industries.
How to use the roll bending machine?
What are the precautions for using the roll bending machine?
What are the specific applications of the rolling bending machine?
1. The barrel of the roll bending machine has a small diameter (that is, a small radius of curvature) and wall thickness. Before rolling with a four-roller plate rolling machine, an arc template should be made, and the sample should be used for pre-bending while checking the pre-bending arc. Bend more, but not too much, this step should be too thin.
2. The roll bending machine is very close to the standard cylinder size, and it is much easier to correct the next step (you can also calculate the pre-bending arc that meets the requirements by calculating the lifting height of the four rollers, but the calculation process is more complicated).
3. If the amount of pre-bending is too large or insufficient after the welding is completed, an arc inclined iron can be used on the coiling machine, and the welding seam at the pout or indentation can be adjusted to produce a qualified tube. body.
1. After checking the interface signal of the machine tool control system with the programmable bending machine control device, and comparing it with the accurate signal of the interface manual, the corresponding fault point can also be found.
2. When the programmable roll bending machine fails, the broken end is memorized in the form of an interrupt stack. Using the plate bending machine programmer, the interrupt stack and block stack can be adjusted when the system is in a stopped state, and the faults can be checked according to the cause of the instructions. This is the most commonly used effective and quick method in the maintenance of programmable controllers.
1. Mechanical Symmetrical roll bending machine
Features: Simple structure, lightweight, easy manufacturing and maintenance, and low investment. The rollers on both sides can be made very close and the forming is more accurate, but the remaining straight edges are large. The disadvantage of this machine is that the end of the plate needs to be pre-bent with the help of other roll bending machines.
Applicable scope and conditions: with pre-bending roll bending machine or all kinds of coiling work that does not require crimping, use the general symmetrical type; the coiling work that requires crimping can use the symmetrical type with a crimping backing plate.
2. Hydraulic three-roller symmetrical roll bending machine
Features: This model is better for large-scale three-roller symmetrical plate bending machines.
Applicable scope and conditions: with pre-bending roll bending machine or all kinds of coiling work that does not require crimping, use the general symmetrical type; the coiling work that requires crimping can use the symmetrical type with a crimping backing plate.
The action result of the roll bending machine is to roll the plate into an arc, which is an important part of the fully automatic production line. ChaoLi Company has worked for several years to meet the need of customers from the industrial production, machining industry, and other fields.
