Machines hydraulic press brakeis a kind of machine with high production capacity and a wide range of applications. It can change the bending mode according to the specific needs of the use environment. Common bending modes include gap bending and bending at the bottom of the pressure. Next, a detailed introduction to the numerical control bending machine bending mode.
1. Clearance bending
CNC bending machine in the bending process, there is no pressure between the upper die and the lower die, by adjusting the depth of the upper die into the lower die opening, you can get the desired bending Angle, this bending mode is called gap bending, the deeper the upper die into the lower die, the smaller the bending Angle; Conversely, the greater the bending Angle. Because the elastic bending of the material also needs to consider excessive bending to control the springback.
2, pressure bottom bending
CNC bending machine bending plate, plate is pressed between the upper and lower die, so as to get the desired bending Angle and elbow radius. Numerical control bending machine bottom bending is suitable for enterprise batch production, if the thickness of the processing of metal plate is less than 2 mm, it should be noted that the bottom bending pressure is greater than the working pressure of the gap bending, generally more than three times.
The control bending machine mold includes a bracket, a working table and a clamping plate. When used, the wire is energized to the coil, and the pressure plate is energized to produce gravity, so as to realize the clamping of the thin plate between the pressure plate and the base. The general usage is as follows:
First, power on, turn on the switch on the control panel, and then start the oil pump. When you hear the sound of the oil pump changing, do not do any operation first.
Two, stroke conditioning, use when it is necessary to pay attention to. Be sure to pass the test before you do the bending assignment. When the upper die goes down to the bottom, it is necessary to have a gap of plate thickness, otherwise the mold machine will be damaged. Stroke conditioning has electric speed adjustment.
Three, sheet metal processing bending slot selection, usually to choose the plate thickness 8 times the width of the slot. Such as the bending of 4mm sheet demand to choose about 32 notch.
Four, the rear stopper adjustment is electric speed adjustment and manual fine tuning.
Five, step on the foot switch beginning bending, CNC bending machine and CNC shearing machine is different, can at any time to loosen, loosen the foot will stop, and then step on the continuous downward. CNC bending machine directly bending, no stitching, no grooving, no need to use welding rod, Angle surface beautiful without water leakage, the technology of welding into automatic machine operation, improve the quality, improve the efficiency of labor, reduce the cost of labor, shorten the production cycle of goods.
The above is the content of the general use of NUMERICAL control bending machine to share with you, for reference. Objectively speaking, bending machine because of numerical control operation, can directly bend the product, and bending product appearance without defects, good quality, for enterprises is not only to improve the quality of production so simple, because the role of NUMERICAL control bending machine for enterprises to improve production efficiency is also huge, This is reflected in reducing labor costs and shortening the production cycle of bending products.
