Shrimp elbow automatic welding upgraded model – robot shrimp elbow automatic welding, using vertical welding process, to obtain beautifully shaped weld, equipment in the process of operation can be real-time monitoring of the operating process, the weld is tracked by laser scanning, in addition to the touch screen can be set up in a number of welding process parameters. There are buttons for start, stop and emergency stop on the operating platform.
Heavy duty shrimp elbow automatic welding consists of 6-axis welding robot, shifter, traveling ground rail, weld scanning system, heavy duty fixture, control system, welding power supply. It is used to replace the manual to complete the automated welding of shrimp bends, the welding process does not require manual intervention, the manual operation is only required to load the material before welding and unload the material after welding. Adopt graphic parameter setting as the basis, laser scanning real-time modeling, fitting the weld to achieve the irregular products of the corrective requirements of the product, the product is simple to operate, easy to use. Reduced weld channel simulation running steps.
General scheme of the control system:
1.1 Overall arrangement:
The system consists of industrial control computer center, Japanese vision scanning sensing system, 5-axis manipulator, double-drive fixture, welding power supply and so on.
1.2 Electrical control system:
Using industrial control machine composed of all-digital control system, the welding power supply, welding head, electric fixture, welding machinery hands control, the exchange of information between the single machine using communication technology, parameters and commands input centralized in the control screen, can be moved to operate, and has a parameter preset and digital display function.
1.3 The control system will have the following basic functions:
* The system has the functions of over-current, over-voltage, under-voltage and emergency stop.
*The system has protection measures for personal safety and equipment safety to ensure safe production.
*Part of the control box and operation panel with emergency stop button.
Adopting computerized all-digital control technology, all welding parameters are digitally displayed and can be pre-set, flexible and convenient operation.
The control station leaves a linkage interface to realize linkage with other products of our company.
***Welding process
The automatic welding machine according to the different welding processes used can be equipped with melting electrode gas shielding welding, tungsten argon arc, such as welding process or a variety of welding processes to achieve the automatic welding of the elbow.
Argon arc welding process and gas shielding welding process used in the field.
□ Argon arc (TIG/hot wire TIG)
□ Gas-shielded (MIG/MAG process)
□Argon arc + gas shielding (TIG/hot wire TIG + MIG/MAG)
***Welding quality
*The bottoming welding can realize one-side welding and two-side molding and weld height control;
*To meet the ray detection, ultrasonic testing Ⅰ or Ⅱ level of weld qualification rate of 98% or more;
*Meet the requirements of pressure test or impact, tensile, bending and other mechanical properties test.
*Angle welding to meet the welding angle height and pressure test requirements.
