Product description

Bending pieces in machining production can often be seen, such as metal to complete V, U, and so on. In the general common situation, there are two methods of metal bending, one is mold bending, the other is bending machine bending, the former is suitable for complex structures, small volume, a large volume of processing. The latter is suitable for processing structures with large sizes and small output. For bending parts processing technology.

One, bending machine bending

Using the bending machine for bending, is mainly divided into ordinary bending and CNC bending two. CNC bending is mainly used for processing high accuracy requirements, bending irregular shape sheet metal bending, its basic principle is to use bending machine bending knife, V-groove, bending and forming of materials. Its advantages are convenient clamping, accurate positioning, fast processing speed, and the disadvantage is that the pressure is small, can only be processed through simple forming, low efficiency.

Two, CNC bending machine bending

CNC bending machine is the use of NUMERICAL control system for the slider administration (punch into the depth of the concave die) and the position of the rear stopper automatic control, in order to achieve bending workpiece bending different degree of bending and bending edge width of the bending forming. The process characteristics of a CNC bending machine are mainly high productivity, can improve the accuracy of bending parts, and the operation is simple, saving the middle stacking area, reduce the labor intensity.

Bending parts of the processing technology

1, free bending

Free bending is a widely used method in production. Free bending mainly uses two edges at the opening of the concave die and the edge of the punch vertex for bending, and the bending Angle is determined by the depth of the punch into the concave die. Free bending requires less bending force, so that the force of the mold is more relaxed, which is of great help to prolong the service life of the mold. But the thickness of the sheet and mechanical properties of the inconsistency will cause a certain change in bending Angle.

2, correct bending

Correction bending is the punch for the rounded corners and straight edge of the workpiece for fine pressure. In the punch downward movement, the blank Angle will be less than the concave die rebound, until the end of the stroke, the convex die to correct the blank, so that its rounded corners, straight edges, bending radius are close to the punch. 

3, three-point bending

Three-point bending is formed by the rounded corner at the entrance of the die and the surface of the pin, which accurately determines the bending Angle. If you want to change the height of the adjustable pin, you can get different bending angles. A hydraulic pad located between the punch and the slide block compensates for the flexural deformation of the slide block and the table so that the material contacts these three points along the full length of the die during punching and bending.
