Requirements for the consistency of the size of the stiffener and the base plate

Dimension tolerance is within 1mm

It is recommended to use laser cutting or plasma cutting to ensure the consistency of the size to obtain a better robot welding effect



Requirements for the size consistency of the door frame

Generally, the door frame is purchased from outside, and the size tolerance is more than 1mm.

Therefore, it is necessary to manually install the door frame, and after the spot welding is firmly (or after the clamping, the robot will weld again, if the tolerance is relatively small, it can also be directly welded by the robot

(Note: If the dimensional tolerance of the door frame is relatively large, it will cause the gap between the door frame and the door to be relatively large, leading to local leakage of welding, and local manual repair welding is required later)

  9. The cutting source is automatic plasma, so the cutting speed will be very fast, and the cut will be smooth and round
  10. Due to the use of the Hypertherm Powermax plasma source and cutting gun, the cutting gap is relatively small, and the cut pieces can be used as door covers
  11. After the electric door is cut, if the door frame needs to be welded, the robot can complete the automatic welding of the door frame. And the door frame welding needs to be equipped with the laser positioning function
  12. The entire machine is designed in the form of a one-way assembly line. The poles are stacked on the left side of the machine. The operator can move one by one to the right to complete the welding, and the welded poles are stacked on the right. The pole moves and rises, no crane is required, and the labor intensity of the operator is low
  13. Save a lot of labor costs
  14. Can adapt to long hours of work throughout the day


Option Items:

Door cutting plasma: Hypertherm Powermax45,suggestion max. thickness 8mm. Option: Hypertherm Powermax65,suggestion max. thickness12mm.

3. flat surface type cutting + pipe type cutting (4 axis)

  1. On the square tube, there are 2 stiffeners on one side. A stiffener device is required, which can be moved up and down, suitable for different positions of the stiffener
  2. The laser positioning function is configured for welding the position and size of parts. The consistency is poor, about more then 1mm. Because the purchased door frame has the same size different, it is recommended that the door frame welded should be equipped with the laser positioning function.
  3. If the small end position is a square tube, the small end support cannot be rotated, and the support type needs to be changed. Add the 12-meter guide rail and the movable support of the small end to improve the accuracy of cutting and welding. It is suitable for round poles, square tubes, and octagonal poles. The small end support is servo synchronous rotation. In this way, it is no longer necessary to make a tooling fixture that turns square to round.
  4. pole bottom expansion tool
  5. stiffener tool
  6. Spare parts for Robot welding
  7. Spare parts for plasma cutting
  8. Networked production data system, the machine is connected to the Internet in the customer workshop,

Function (1):

can provide production management data: power on time, welding time, cutting time, non welding time, production quantity, etc

Function (2):

After the machine is connected to the Internet, the machine supplier can assist the customer in remote fault diagnosis and remote parameter adjustment. Convenient for customers to quickly resume production.
