A new member has been added to the intelligent manufacturing robot family of Henan Mine—the double-beam main beam inner seam robot welding workstation.
This workstation is mainly used to realize the automatic welding of the inner seam of the main girder of the double girder. After the manual feeding is basically centered in the horizontal and vertical directions, the workpiece is turned ±90° by the L-arm hydraulic turning machine, and the robot automatically seeks the welding position.
Why such a workstation?
1. Save welding personnel, reduce labor costs, improve production environment and optimize management.
2. The robot can work uninterruptedly for 24 hours, can organize production with high intensity and high efficiency, is not affected by personnel factors, improves equipment utilization rate, and shortens product delivery cycle.
3. The robot eliminates the safety hazards of manual operation and can avoid unnecessary safety production accidents. Strict standardized operation, high process stability and stable productivity.
4. Improve the image of Henan mining technology and strength, improve the strength and quality of product welds, and become more competitive in the market.
Main features of the workstation:
1. Satisfy the welding of the rib plate and the inner weld of the web (the inner weld of the web and the upper cover plate can also be welded).
2. The welding of the inner seam of the main girder adopts laser plate-seeking + robot welding program to realize automatic welding.
3. The L-arm hydraulic turning machine is equipped with a contact sensing system to automatically align the workpiece.
4. A key switch is provided to prevent accidental operation of the equipment when personnel are loading materials.
5. The welding program adopts parametric programming, and the size parameters are input in the teaching pendant to automatically determine the welding position.
All motors and key components are protected against water and dust, and the protection level reaches or exceeds IP54.
The robot welding process has greatly improved the quality of the welds and improved the efficiency of the welding of crane structural parts, especially in the welding of the inner welds.
Traditional manual welding requires workers to drill into the workpiece to perform welding. The extremely harsh environment of smoke, dust, strong light, and high temperature seriously endangers the health of the operator. Robot welding completely avoids such problems.
