Henan Mine intelligent manufacturing robot family has added a new member - Robot welding workstation for main girder inner seam welding of double girder.
This workstation is mainly used to realize the automatic welding of the inner seam of the double girder main gird. After the manual feeding to align the midpoint of horizontal and vertical, By the L arm hydraulic turning machine performs the workpiece ±90° flipping, and the robot automatically seeks the welding.
Main girder of double girder inner seam welding battle
***Worker team.
Working in the girder box is easy sweat and connect electricity
Welding smoke is harmful to human body
Welded welds are uneven
It takes 3-4 hours to weld the inner seam of a main girder.
PK
***Robot team.
Automatic welding requires no manual labor
Weld well-formed
Product consistency
Weld the inner seam of a main girder within one hour
Why install a workstation like this?
1. Save welding personnel, reduce labor costs, improve production environment and optimize management.
2. The robot can work 24 hours without interruption, and can organize production with high intensity and high efficiency without being affected by human factors, so as to improve equipment utilization rate and shorten product delivery cycle.
3. The robot can eliminate the potential safety hazards of manual operation to avoid unnecessary production safety accidents.Strict standardization operation, high process stability, stable productivity.
4. Improve the image of Henan Mine technology and strength, improve the strength and quality of welding seams, and become more competitive in the market.
Main features of workstation
1. Meet the welding requirements of the internal welding seam between the rib plate and the web plate (the internal welding seam between the web plate and the upper cover plate can also be welded).
2. The main beam internal seam welding adopts laser seeker plate and robot welding program to realize automatic welding.
3.L arm hydraulic turning machine is equipped with contact sensing system, which can automatically correct find the right location of the workpiece.
4. Set key switch to prevent accidental operation of equipment during personnel loading.
5. The welding program adopts parametric programming to input dimension parameters in the teaching device and automatically determine the welding position.
6. All motors and key components shall be protected against water and dust with protection grade up to or above IP54.
Two more such stations will be installed next month.Robot welding technology, greatly improve the quality of welding seams, improve the efficiency of crane structural parts welding, especially in the internal welding showed a greater advantage.
Traditional manual welding requires workers to drill into the workpiece internal to weld. Smoke, dust, strong light, the extreme environment of high temperature, seriously endanger the health of the operator. While the use of robot welding is completely to avoid such problems.
The establishment of automatic double girder inner seam robot welding workstation is another measure for Henan Mine to care for employees and improve quality and efficiency.
