Automatically Big Metal Pole/ Pipe close and welding machine--for pipe making machine
Suitable for big metal pipe close and welding, the pipe making steps:
1. because some pipe is very thick, in order to make sure the perfect round shape, before press brake bending, it needs to Pre-bend two edges
2. After pre-bend, then we put the plate on press brake machine to bend round/ circle shape
3. After bending, then pipe will have gape, at this momonet, we need this close and welding machine to close the gap, then welding, during the welding process, the pipe is fixed, not move, just the welding gun moves
Big diameter pipe/tube close gape and welding machine
Equipment main purpose and performance
Automatic closing and welding machine is used for automatic closing and welding for straight seam pipes.
It comprises main machine, welding power, mechanical welding seam center adjustment system and central control system. Its main machine has hydraulic closing mechanism, press rollers, machine frame, pipe conveying trolley and rail.
Suitable process range and welding process
Automatic closing and welding machine consists of motorized closing seam main machine, welding system, pipe conveying system and control system
The main part of Straight seam pipe automatic closing and welding machine is Mechanical closing seam machine. It is composed of gantry type frame, upper press roller device, side press roller device, crossbeam, and bottom supporting trolley. Four sides press rollers will close the bended pipe, make the seam smallest, and control the seam axial misalignment, and press roller is driven by hydraulic system.
2. Mechanical welding seam tracking system
Adopt guide wheel blocking in the welding seam, force the welding gun and seam are in the same line, avoid welding seam off-tracking during the welding process
3. Welding system
Welding system is comprised of gas shield welding system, motorized plus shape carriage, automatic water-cooling welding gun and recycle water cooling system. This part will finish pre-welding for pipe.
Inputting system is composed of feeding trolley, pipe positioning device and steel rail. It is used for pipe conveying. The welding method of this system is pipe moving, welding gun fixed way to weld.
Feeding trolley driving system adopts gear and rack meshes, to make sure the stable running.
Steel rail use 43 kilos heavy rail, to make sure the straightness
The trolley has two speed, during the welding, it runs slowly, during returning, it runs fast.
The steel pipe closing system is the key part of this equipment. During the pipe bending process, the pipe will have some defect, which will bring difficulty to closing seam. We adopt three points adding pressure, two points supporting way to solve this problem.
Closing system includes left-right press rollers, up and bottom press rollers, up and bottom supporting carriage
The left-right press roller requires high-accuracy synchronization, and is driven by cylinder with hydraulic synchronization device.
Up and bottom press rollers will press and flat the seam, to avoid seam misalignment.
Up and bottom supporting carriage is fixed type, and mounted in trolley.
6 control system
Using PLC to realize program control, and pipe driving motor is inverter stepless speed regulation, constant torque output
The equipment has numbers of testing and safety protect device, and equipped with 1 set of main control cabinet and 1 control box.
In the control box, it sets big-screen human-computer interface, we can make digital setting for welding parameter and equipment function
Our machine has advantage of modularity, mechanize, and automation
