Use steps of large press brake

The large press brake is a machine that can bend paperboard and is widely used in various fields.Today we will look at the steps of using the large press brake.

The following knowledge points are listed below:

Preparation before work in the large press brake

Use steps of large press brake

Large press brake is a kind of can be carried out on the thin plate bending machine, the structure mainly includes the bracket, workbench and clamping plate, workbench on the scaffold, workbench consists of base and the clamp, the base through the hinge is connected with the clamping plate, large press brake base is composed of shell, the coil and plate, coil placed inside the shell of the sag, the depression at the top of the cover plate.In the use of the large press brake, the wire is electrified to the coil, and after electrification, the force of gravity is generated on the pressing plate, so as to achieve the clamping of the thin plate between the pressing plate and the base.As the large press brake adopts electromagnetic force clamping, the platen can be made into a variety of workpiece requirements, and the workpiece with side wall can be processed, the operation is also very simple.

　1. Preparation before work in the large press brake:

(1) prepare necessary operating and measuring tools, molds, Angle ruler, tape measure, calipers and depth calipers.

(2) carefully read the drawings, measure the parts to be processed should meet the size and technical requirements of the drawings, parts that do not meet the size and technical requirements of the drawings are not allowed to bend, and timely report to the relevant departments.

(3) check the length, width and thickness of the material, and the direction of the grain should conform to the molding characteristics. The large press brake should be clean and hygienic.

(4) according to the drawing process requirements, replace the corresponding mold, and remove the excess upper blade row when bending parts of smaller size.

(5) according to the drawing process requirements, determine a reasonable bending sequence, bending processing;For the large press brake, the program should be run empty once and then bent.The important parts should have the test piece processing verification procedure, the first piece inspection, every one of the bending processing inspectors should carry out an inspection, correct the deviation.

2. Use steps of large press brake:

1) first, switch on the power, open the key switch on the control panel, and then press the oil pump to start and the large press brake does not operate at this time .

2) Attention must be paid to adjusting the distance of the large press brake, and the large press brake must be tested before bending.A plate thickness gap must be ensured on the bottom of the large press brake.Otherwise it will cause damage to the mold and machine.The adjustment of stroke also has electric quick adjustment and manual stomach adjustment.

3) . The choice of bending slot, generally to choose 8 times the width of the plate thickness of the slot.If the bending of 4mm sheet material, need to choose about 32 slots.

4) rear stopper adjustment generally has electric quick adjustment and manual fine tuning.

5) the large press brake can be released at any time. The large press brake can be released at any time.
