Core component：

1.Tooling

Press Braker Tool:Mold for punching and separation for plate stamping
The bending machine is used to form the tools for processed plates. This tool consists of various parts, and different molds are composed of different parts.It mainly achieves the shape of the item through changes in the physical state of the forming material. Under the action of bending machine pressure, the blank material becomes a tool with specific shapes and sizes. Divided into the upper and lower molds of the bending machine, for the stamping and forming of the plates and
Separate mold. The mold for forming has a cavity, and the molds for isolation have a blade.

Tooling Section:

The choice of bending mold depends mainly on::
Board thick:
Different plate thickness will lead to the different opening of the bottom mold. The tonnage that needs to be bent is different. The loads generated by the mold are different. The R arcs of naturally shaking are different. These will have an important impact on the choice of mold selection. Essence
The shape of the workpiece:
The choice of mold shape depends on the shape of the workpiece, and the mold needs to be interfered and influenced by the molding trajectory of the workpiece.

2.Crowning Compensation

In view of the mechanical structure of the bending machine, the force at the oil cylinder on both sides is different from the middle part of the middle part, so when the long -term workers are bent, there will be a bending angle deviation between the two ends and the middle part. The deflection compensation function of the bending machine is corrected.

Types and principles of crowning compensation:

Hydraulic compensation:

Hydraulic compensation is composed of a set of hydraulic oil cylinders installed on the bottom plate. The location and size of each compensation tank are designed according to the deflection curve of the slider and the finite element analysis of the workbench. Shift to achieve raised compensation of the neutral board.

Mechanical compensation:

Mechanical compensation is composed of a set of band -slapped wedge blocks with a set of sloping. Each biascope is designed based on the deflection curve of the deflection of the slider and the workbench's finite element analysis. The CNC system calculates the compensation volume according to the load capacity of the workpiece, and automatically controls the relative displacement of the convex sclavic wedge block to achieve a pre -bump, so that the gap between the upper and lower molds is consistent.

Mechanical compensation can get accurate deflection compensation on the entire workbench
●Stable and lasting, reduce maintenance frequency
(Situation of no liquid voltage cylinder oil leakage and other conditions)
●There are more compensation points, bending workpieces can achieve linear compensation methods, improve workpiece bending effect
Return to the signal position through the potential ruler measurement, and achieve digital control as a CNC axis, it is more accurate compensation value
●Adding convex oblique wedge to preheat before the bend starts, high repeat accuracy high

3.Backguage

The role of the post material:
It is based on the bending process of the positioning function of each bend.
The position of the post -gear position is automatically calculated by the CNC system based on the bending shape of the workpiece; and the positioning output is performed in turn according to the bending process. You can get accurate bending positioning.
