Buy high quality hydraulic press brake skills and pay attention to the thickness of the bending plate

When we buy high quality hydraulic press brake, often do not know what is the appropriate CNC bending machine, then how to choose CNC bending machine? How can I avoid being fooled? Bending machine manufacturers to introduce you to the purchase of hydraulic press brake five steps and skills:

backside

1: First of all, according to their own demand parameters, determine the specifications of the machine to buy, but also take into account the need to expand the size of the enterprise to leave a certain amount to determine the parameters of the machine. In particular, CNC bending machine, the range of material thickness requirements, after the machine model parameters are determined, you can contact manufacturers to buy.

2: what are confirmed to purchase CNC bending machine manufacturers, it is often overlooked, because no matter which manufacturer, manufacturer will inform specializing in the production of this product type, basically the facts, often have different models, different manufacturers, manufacturers usually through the transfer of goods to provide various types of products, therefore, the user should pay special attention to choose the right.

3: with many CNC bending machine production company contact, the price of the machine is usually in the choice of high and low price, choose a trustworthy manufacturer, so that you can get a better cost performance, while ensuring quality and after-sales service.

4: Select some special manufacturers for comparison, to learn more about the use of machine tools, machine quality, especially after-sales service information. Comprehensive consideration of many aspects, choose the most preferential price, the best service manufacturers.

5: After confirming the manufacturer, the next step is to sign the contract for payment, payment or cash on delivery.

Only through the preparation work and step by step to complete the steps, to buy a satisfactory CNC bending machine products.

The operation of the bending machine should pay attention to the thickness of the bending plate. In the bending process, the bending force required by the metal plate is proportional to its thickness. The greater the thickness of the sheet metal, the greater the bending force required, the required equipment tonnage also increased.

In the bending of the metal plate bending before the V-shaped planing slot, so that the remaining thickness of the plate is greatly reduced, so that the bending force required when the plate bending will be correspondingly reduced, CNC bending machine so that the thick plate can be bent in a smaller tonnage bending machine. This not only reduces the investment in equipment, but also saves energy and site.

How to avoid bending Angle and size deviation

The quality of bending forming mainly depends on the two important parameters of bending Angle and size. When bending, in order to ensure the bending shape size and Angle, we need to pay attention to the following aspects.

(1) The upper and lower die on the knife is different, will lead to the bending size error, bending before the upper and lower die tool for the center adjustment.

(2) After the left and right positions of the rear stopper block move, the relative position of the sheet and the lower die may change, which affects the bending size. Before bending, the position distance of the rear stopper block should be determined again.

(3) The parallelism of the workpiece and the lower die is not enough, which will cause the bending rebound and affect the bending Angle. Before bending, the parallelism needs to be measured and adjusted.

A bending Angle is insufficient, two bending will also be affected, bending error will lead to the accumulation of workpiece forming size and Angle error, so it is particularly important to ensure the accuracy of unilateral bending.

5 when bending, the size of the bottom die V mouth is invertively proportional to the bending pressure, in the processing of different thickness of the metal plate, the need to choose the appropriate bottom die V groove, generally choose 6 ~ 8 times of the plate thickness is the most appropriate.

The workpiece in the plane after the V-shaped slot in the bending machine for bending, to ensure that the ambiguous edge, the bottom of the v-shaped slot and the bottom of the die v-shaped slot in the same vertical surface.

When bending the workpiece after planing, in order to prevent knife clamping, the upper die Angle should be controlled at about 84°.

As a new type of bending process, grooving process is the result of market selection. With the continuous development of technology, enterprises have higher and higher requirements for technicians. As a technologist, we can only make better products by mastering various processing techniques. Only by constantly exploring and pursuing new technology, can we produce more excellent products.
