Description

CNC Bending Machine for Metal Sheet Bending

A bending machine is a tool used to bend metal sheet into various shapes and angles without breaking or damaging the material. It utilizes computer numerical control (CNC) technology to precisely control the bending process. Oil-electric hybrid CNC bending machine is equipped with hydraulic and electric servo systems that exert pressure on the metal sheet, allowing it to be accurately bent into desired shapes and angles.

These machines apply force to the metal, either manually or through automation, to achieve the desired bend. Bending machines are commonly used in industries such as automotive, construction, shipbuilding, and metal fabrication.

After annealing process.To eliminate stress and deformation, ensure the accuracy and stability of the workpiece size, linear guide rail installation surface through fine milling, fine grinding, flatness is less than 0.03mm, to ensure the dimensional accuracy of the workpiece, the rear block die beam design is unique, coupled with the beam fine-tuning parallel technology.

Ensure that the parallelism between the beam and the center line of the slide is less than 0.1mm, which can effectively control the full length of the workpiece to ensure that the material is within 0.1mm. There is also a backstop function to avoid the interference of processing on the workpiece. The modular design controls the number of axes available from single axis X to multiple axes.

Mechanical compensation device.

(electro-hydraulic machine standard, twisted shaft machine selection)In the process of bending the workpiece, the slider and the table exert pressure on the plate at the same time, the upper slider will inevitably produce bending deformation, so that the bending Angle of the workpiece is small at both ends andlarge in the middle, and is deformed by the reaction force of the plate, affecting the Angle of the workpiece and its straightness. The workpiece needs to be compensated.

The compensation mechanism is controlled by CNC numerical control system, whichmakes the lower table produce pre-convex to compensate the bending deformationof the upper slider, and controls the Angle change of the workpiece within thetolerance range to ensure the bending accuracy.

CNC sheet metal bending machine using steps

How to learn to use CNC sheet metal bending machine?

How to use CNC sheet metal bending machine? Regarding the introductory operation tutorial of CNC sheet metal bending machine, I believe that many users have seen many versions. There are detailed explanations in pictures and texts, as well as video operations. The content is very detailed, but people who read it may find that the content is too much. Standard and official, it is a bit difficult to understand. Therefore, many users want to watch some easy-to-understand tutorials, the following content we will share with you how to simply use the sheet metal bending machine, everyone will know at a glance.

Getting started tutorial on CNC sheet metal bending machine

First of all, before operating the CNC sheet metal bending machine, we need to understand the equipment components of the CNC sheet metal bending machine. Its overall structure is mainly divided into three parts: the bracket, the clamping plate and the working table. Indispensable, in the process of use, you must ensure that there are no problems with the three before you can continue to operate. The principle of use of the CNC sheet metal bending machine is that when the wire and the coil are energized, it will generate a gravitational force on the pressure plate. When the gravitational force is generated, the clamping between the pressure plate and the base can be realized, so as to realize the bending of the sheet. The specific operation The tutorial is as follows:

  1. Preparation for power-on

To use the CNC sheet metal bending machine, the first thing to do is to turn on the sheet metal bending machine first. We need to turn on the power switch on the control panel of the sheet metal bending machine, and then start the oil pump. If we hear the oil pump The sound of rotation means that there is no problem with the sheet metal bending machine. At this time, we don’t need to do any work and let the oil pump run idling for about 80s;

  1. Stroke adjustment test

In the second link, we need to test the machine and adjust the stroke. The specific operation is mainly to keep the thickness of a sheet when the upper mold goes down to the bottom position. This step is to ensure that the sheet metal bending machine can work normally. The important link that does not affect the life cycle of the sheet metal bending machine must not be ignored;

  1. Choose a slot

The thickness of the bending and the size of the notch are selected in this step. The program is set according to the actual standard. Within the industry standard, the size of the notch is determined by the thickness of the sheet. Normally, the thickness of the sheet is 8 times. The width of the socket size, for example, when bending a 3mm sheet, you need to choose a 24mm slot, the calculation is very simple;

  1. After adjusting the gauge

This step is mainly to confirm the position of the back gauge and the degree of standardization to ensure that it can work normally;

  1. Step on the switch to work

After the above preparations and testing work are completed, we can step on the switch to start sheet bending. It should be noted that the pedal of the sheet metal bending machine can be released at any time. The principle of releasing and stepping is to step on. Release and stop, it’s very simple.

The above is a very simple and practical CNC sheet metal bending machine introductory operation tutorial content to share with you, for those who need it for reference. Objectively speaking, because the sheet metal bending machine is a CNC operation, the product can be bent directly, and the appearance of the bent product is flawless and the quality is good. For the enterprise, it is not only as simple as improving the production quality, because the CNC sheet metal The bending machine also plays a huge role in improving the production efficiency of enterprises, which is reflected in the reduction of labor costs and shortening the production cycle of bending products. Finally, I would like to remind everyone: before and after using the sheet metal bending machine, the sheet metal bending machine needs to be inspected and maintained. This is also a very important part of the work. It can ensure and extend the CNC sheet metal bending machine. Use life cycle.
