Production Introduction:
1. We use Electro-hydraulic servo system, closed loop control system controls precision

2. The unique patented technology:bilateral deflection compensation of the large press brake
3. Open width adjustable inserts die to meet a variety of workpieces
4. A variety of auxiliary institutions could meet user's requirements and make the process more convenient and efficient

5. Y1,Y2 Axis------Two raster displays installed at both sides of ram to control cylinders.

Machine Main Performance :

1 .The frame of machine is composed of tank, worktable, left and right housings and ram. So it has high strength and good rigidity. Also it takes vibration to eliminate stress.

2. Synchronization working principal of both machines:Adopting electric-hydraulic proportional valve to ensure the synchronization of both machines. The proportional valve is made by BOSCH company with very good performance such as small friction between mechanic action pairs, fine electronic amplifier and electric magnet with high controlling force and continuous action. There are two raster displayers on both sides of machine to inspect the position of ram continuously and feed back the signal to control system, then the control system will control electric-hydraulic valve to make two cylinders synchronization on one machine. Because the raster displayers are installed to “C” plates, not on housing plates directly, the deflection of ram and frame when working will not effect its measuring and controlling precision. When two machines working together, the differential potentiometer installed between two machines will transfer the mechanic synchronizing signal into electronic one and feed back to synchronization plate and control system. The signal will be enlarged by BOSCH amplifier to control the synchronization of both machines by controlling electric-hydraulic proportional valve. So the synchronization of two machines is achieved with high precision.

3 Through computer,the operator could communicate with machine. The computer has several service language, calculate and adjust the bending force automatically. Also it could calculate and control the dead point, speed changing point.The strokes (Y1, Y2) of ram could make a small tilt to meet the special requirement of user.

4. Equipped with good guiding system, position measuring system and hydraulic balance system to meet the requirements of full length job and eccentric job.

5. Worktable compensation unit is adopted to make up for deflection of machine when working to make sure the precision of work piece.

6 .The surface of cylinder has good wearing and heat treatment, so it has good lubrication and long service life.

Pipe making process:


1. Breach machine

What kind of breach machine we need is according to the quality of custom’s product making. Finally we can recommend an economic and useful one to suit you well then. What you see below picture is about breaches for two sides for good next welding.


2. pre-bending machine

We need to get working piece pre-bend at two ends of plate as the following picture for making a good pipe. Obviously there are two ways to make it. One is pre-bending machine and the other is press bake machine itself, but we don’t recommend the last way for the big work piece for long time use. Because of big work piece and big lateral force, it’s obviously easily to damage the machine.

For example, The following pipe finally made you see is without pre-bending. I don’t think it is the right pipe you want. So pre-bending is important to the pipe and what kind of machine is used for pre-bending is important as well. It does have relationships to pre-bending quality, work efficiency and so on.

3. CNC press brake machine

We need a press brake machine to finish this kind of pipe. Of course, besides round-shape pipe, it also can make polygon pipe and bend for any other angles as well. Obviously we will make this pipe with many bending times. The size of seam is according to the thickness of upper tooling holder. Thinner of upper tooling holder and smaller seam.


4. Automatic Closing and Welding Machine

We need this kind of machine to get seam close and welding. See as following picture.

Gas shielded arc welding is at the bottom of outside seam first to prevent seam opening. We don’t need to remove it any more. Because it is different from submerged welding, no Submerged arc welding flux drops.


5. Pipe inside Welding Machine


We need this kind of machine to weld the seam with Submerged welding inside pipe. The machine is consist of welding trolley, welding system, mechanic device, welding grounding device, inside welding monitor system, welding flux feeding and recycle device, and control system. Adopt trolley to move pipe, the welding gun fixed type.

Finally it would be like following picture after Pipe inside Welding Machine.


6. Pipe outside Welding Machine


We need this kind of machine to finish pipe outside welding as following picture.


7. Steel Pipe Straighten and Round straightening combined Machine


This kind of machine is used to make the steel pipe straight and round completely.



Regarding all kinds of machine details you have to contact Stacy who is an expert on making a pipe. She has already offered many successful solutions for different customers for different pipe.
