Automatic crowning system

CNC bending machine  is an important equipment in sheet metal processing, and its working accuracy directly affects the bending accuracy of the workpiece. During the bending process of CNC bending machine, due to the maximum force at both ends of the slider, the reaction force of the plate bending causes concave deformation on the lower surface of the slider, and the deformation variable in the middle part of the slider is the largest. The angle at which the workpiece is bent varies along the entire length.

Note when using CNC bending machine

• Check whether the fastness of each part of the sheet metal machine tool is good; the slider runs 3-5 times at full stroke for about 2 minutes when the equipment starts idle. Pay attention to whether the equipment runs smoothly without abnormal sounds, and stop to troubleshoot if necessary.
• Selection of bending dies, including upper die and lower die. The selection of the upper die needs to be determined according to the required angle and length of each side of the actual sheet metal workpiece, etc., and the feasibility of bending must be fully considered; the selection of the lower die needs to be determined according to the thickness of the metal sheet that needs to be bent, and the lower die with a notch width of 10 times the thickness of the plate should be selected.
• Skateboard stroke adjustment. You must pay attention to adjusting the stroke before using the CNC bending machine, and be sure to test the machine before bending. There must be a gap in the thickness of the sheet when the upper die of the CNC bending machine goes down to the bottom. Failure to do so will cause damage to the mold and machine.
• After setting the parameters and stroke, etc., step on the foot switch to start bending. Unlike the shearing machine, the CNC bending machine can be released at any time, and the CNC bending machine stops and then steps on to continue downward. This ensures work safety and bending accuracy.
• When it is found that the mold or workpiece does not need to be adjusted during the work process, it must be adjusted in the shutdown state, and manual correction is strictly prohibited during the operation of the machine tool.

CNC bending machine maintenance methods

1. Lubrication

Lubrication of CNC bending machines is very important. A well-lubricated machine can effectively reduce mechanical damage and improve the working efficiency and service life of the machine. Lubrication of the CNC bending machine is essential. Lubricating oil not only reduces mechanical friction but also cools and cools, seals and leaks, prevents corrosion, damping and buffering, cleaning, etc., and increases the service life of the machine tool.

CNC bending machines are generally equipped with lubrication devices. The main categories are butter nozzle, manual oiler, electric oil injection, etc. Please regularly lubricate according to the machine belt instructions.

2. Clean the lower countertop

The degree of cleaning of the lower table surface of the CNC bending machine has a direct impact on the bending accuracy, so we should pay attention to cleaning the lower table surface frequently during the use of the Liangfa Ji brand CNC bending machine and wipe the lower table surface with a rag to ensure that there is no oil pollution, no debris, no yellow robe.

Electric box maintenance

As the control element of the machine tool, it is very important to ensure the normal operation of the electric box, so we need to maintain it frequently during use. The basic points of sheet CNC bending machine electric box maintenance are as follows:

1. Clean the heat dissipation window of the electric box

CNC bending machine, each element of the electric box will generate a lot of heat in the process of operation. If the heat dissipation of the electric box is too high, the internal temperature will greatly shorten the service life of the internal components and even directly cause the components to burn down, so the heat dissipation of the electric box is very important. Clean the exhaust fan once with an air gun in the state – blow from the inside out, subject to no ash build-up on the exhaust fan and exhaust window.

2. Fastening of internal components and terminals of the electric box

In the process of using the machine tool, the internal components of the CNC bending machine electric box will be loose due to jitter and other reasons. Loosen fastening screws are easy to cause component drop damage, and loose connection heads will cause poor contact to affect the machine tool processing accuracy and The service life of the electronic components of the machine. The internal components are checked for fastening, usually once a quarter.
