Some users will find that the bending machine in the use of the process will appear uneven pressure, and uneven pressure will lead to uneven bending machine upper and lower press brake tools force, resulting in the bending of the product to appear a certain degree of error, which in turn affects the normal production activities of the enterprise link.So the face of the bending machine uneven pressure on both sides of the situation users in the end how to do it? We will come together to understand the specific solutions.
- The bending machine on both sides of the pressure is not the same reason：
Bending machine pressure uneven first we need to find the causes of the problem, only to find the problem in order to solve the problem, specifically the bending machine uneven pressure on both sides of the main reasons for the emergence of two, one may be for the bending machine’s own reasons, the other is for external reasons.
- The bending machine pressure is not the same on both sides of the detailed solution:
First of all, if the external causes, such as bending machine near a heavy object affects the work of the cylinder on both sides of the slider force is not uniform, then we just need to move away from the heavy object, and let the bending machine to return to the normal movement of the two work cylinder slider can solve the problem.It should be noted that some users in the use of bending machines often do not pay attention to the bending machine cleaning and maintenance, which is incorrect. Before using the bending machine, we need to ensure that the bending machine body without foreign objects, and always pay attention to the work of the bending machine, which can effectively reduce the bending machine uneven pressure on both sides of the situation.
The second bending machine uneven pressure on both sides of the reason is the most common situation, which is caused by the machine itself. Mainly because of the two working cylinders at both ends of the slider for pressure, which leads to the center of gravity of the bending machine to the middle of the work, while the center of gravity of the bending machine to the middle of the work will lead to bending the product on both sides of the force is not uniform, uneven force naturally affects the molding of the product as well as the subsequent work.For this reason in general need to use “deflection compensation and pressure compensation” to solve. Specific operation in the slider and bending machine on the table between the upper die placed on the table with the force of deformation in the opposite direction of the deformation to achieve the slider, the table variable compensation, prompting the bending machine on both sides of the cylinder slider pressure distribution is more uniform.In addition, the deflection compensation can also be realized using hydraulic and mechanical compensation, which are very common solutions, and the specific implementation of the operation of the bending machine manufacturer’s manual will also have the corresponding tips.
三,Bending need to pay attention to the problem:
- Angular deviation:
Keep the work piece in contact with the bending mold: In the bending process, the work piece should be firmly in contact with the bending press brake tools in order to ensure the accuracy of the bending angle.
Adjusting bending parameters: For example, increasing the bending force or decreasing the strain rate can improve bending accuracy.
Optimize the bending process:For example, the angle of the die can be adjusted appropriately and fine-tuned during the bending process to reduce the angular deviation.
- Bad bending:
Check for work piece damage:During the bending process, deformation of the work piece can lead to poor bending and the work piece needs to be checked for damage.
Replace worn out molds:Molds may wear out during use, resulting in poor bending and need to be replaced in a timely manner.
Adjust bending parameters:For example, increasing the bending force or decreasing the strain rate can improve bending accuracy.
- Deformation:
Use a smaller strain rate or increase the bending strength to reduce the deformation of the work piece.
According to the characteristics of the work piece to choose the right mold, in the bending process can avoid the deformation of the work piece.
Strengthen the operator’s skills training, reasonable operation of equipment, and pay attention to strengthening the maintenance of equipment
- Hydraulic system problems:
The hydraulic system of the CNC bending machine sometimes fails, resulting in unstable pressure. In this case, it may be necessary to replace the hydraulic oil, check the oil circuit, solenoid valve and other key components, and carry out repairs. Check whether the hydraulic oil is replaced within the specified time, and whether there are air bubbles and contaminants.
- press brake tools issues:
Factors such as the shape, material and process of the press brake tools will affect the productivity and quality of the bending machine. If there are problems with the mold, such as deformation, wear and tear, material problems, etc., it will lead to unstable pressure. At this time, it is necessary to check and repair the mold, check whether the press brake tools is in good condition, including whether there are cracks, damage, deformation and other phenomena, as well as the press brake tools material, thickness, size, etc. Check and repair.
- Improper operation:
Improper operation is another common cause of pressure instability. For example, the operator interface parameters are wrong, feed speed and pressure settings are wrong. In this case, you need to pay attention to the operation specification, check and correct the wrong operation, check and adjust the parameters of the bending machine, feed speed, pressure, etc., to ensure that the equipment is in the best state, but also need to standardize the operation process, follow the correct operation specification.
Summary:
CNC bending machine pressure instability problem has many reasons, the need for different problems for the appropriate solution. It should be noted that the operation of the bending machine should be standardized, so as to ensure the normal production of equipment, to ensure that the production efficiency and quality improvement.If the user in the process of using the bending machine in the process of these situations can directly call the bending machine manufacturers of after-sales service contact number to help solve the problem, which is a relatively quick solution. In addition, the bending machine pressure is not the same on both sides is a common problem, generally speaking, the regular manufacturers in the completion of the sales work will be carried out after the professional training of technical personnel, so the purchase of bending machine must choose the regular brand manufacturers like us HOGI. We have a good after-sales service, can promptly solve the problem, there will be corresponding and detailed product manuals will also have video to assist and will carry out staff training.
