What is the difference between WC67K-200T3200 Hydraulic Press Brake machine and CNC folding machine?

First of all, summarize the main characteristics of the two:

WC67K-200T3200 Hydraulic Press Brake machine: the upper and lower die are respectively fixed on the upper and lower table of the bending machine, and the relative movement of the hydraulic drive table is combined with the shape of the upper and lower die, so as to achieve the bending forming of the plate.

CNC flanging machine: the motor drives the upper slider to press the plate, and the flanging beam rotates from bottom to top to drive the plate to bend and form.

Numerical control bending machine and numerical control folding machine in sheet forming, from the following six aspects of the characteristics of comparison:

The forming principle is different

Bending machine - by controlling the amount of pressure on the knife to control the bending Angle, in the bending short side, the operator needs to hold up most of the material in the outside, in the large workpiece bending, need two or more employees to cooperate.

Edge folding machine -- after the plate is placed flat on the work table, the edge holder beam is pressed down to fix the plate, and the edge folding beam is turned up and down to achieve edge folding. In all edge folding processes, manual positioning and auxiliary turning and positioning are no longer needed.

The bending accuracy is different

Bending machine - the dimensional accuracy of the control is the short edge dimensional accuracy of the rear stopper positioning, after the completion of bending, so the error accumulated to the internal dimension, at the same time due to the control of the bending Angle of the knife die pressure, so the Angle is related to the thickness of the material.

Flanging machine - control dimensional accuracy for the completion of the first flanging, the first edge as a positioning reference, so as to control the size of the customer's requirements of the internal dimension, at the same time, bending Angle for direct control flanging Angle, and material thickness has no relationship.

(3) Material surface scratch damage problem

Bending machine - when working, the material will produce relative movement in the cutting die, without surface protection, will leave indentation. When bending large workpieces, it is necessary to turn over and move for many times, which will inevitably produce scratches in the process.

Flanging machine - During operation, the holder beam cutter and the flanging beam cutter do not move relative to the material, thus completely avoiding surface damage. Large workpiece in bending, because the plate is flat processing, at the same time a positioning can be completed on one side of the workpiece all processing, completely avoid surface damage.

(4) The technical level of workers is different

Bending machine - the technical level of bending workers relatively higher requirements.

Folding machine - programming can be intuitive with finger painting way to achieve programming or by engineers using software offline programming and the use of USB or network connection to import processing procedures, after the completion of programming, the main work of workers into a simple loading and unloading work, without skilled bending workers.

⑸ Tool configuration

Bending machine - different thickness, shape of the product, need different up and down mold, in the realization of some special bending (such as arc) requirements, need to replace the tool or transfer to another machine tool to achieve, increase the transfer of semi-finished products and temporary storage work.

Edge folding machine -- by configuring the rotating edge holder beam and installing two sets of edge holder beam cutting tools at the same time, realize the single position to complete all bending processes, for arc bending or other special bending requirements, basically do not need to replace the tool, just modify the program that can be fully realized.

⑹ Tool life

Bending machine - because the workpiece has relative movement in the tool die, the tool will wear, need maintenance or replacement.

Edge folding machine - basically avoid the relative movement between material and tool, tool long-term use almost no wear, greatly extend the tool life.

⑺ drive system

Bending machine - hydraulic drive, bring more maintenance work and vulnerable to environmental factors.

The folding machine adopts full electric drive design to reduce the maintenance workload and is independent of the operating environment, thus achieving higher bending accuracy.

系统

⑻ the faults of the hem machine

1) Due to the different bending principles, the R Angle of the folding machine is larger than that of the bending machine;

2) Limited by the support table, the workpiece on both sides of the turn down can not be processed;

3) The workpiece size is limited by the upper mold pressing area, and the workpiece size smaller than the pressing area can not be processed;

4) Efficiency is not as high as bending machine;

5) Due to the structural characteristics of the bending machine and the diversity of the mold, some complex shapes can be simply realized by the bending machine, relatively speaking, the flexibility of the folding machine is poor;

6) Flanging machine is currently widely used in Europe and the United States, we are affected by the traditional Japanese processing concept, generally adopt bending processing, no better use of flanging machine.
