Numerically Controlled Center Groove Welding Machine (Zhengmei Machine)
The CNC middle slot welding machine is mainly used for surfacing and cladding the surface wear-resistant layer on the angle welds of coal machine middle slots. Its applications and features are as follows:
Based on the nine-axis CNC system, we have developed a secondary version that can be expanded with features according to process requirements. This versatile machine covers common welds on the middle groove, such as 12mm, 15mm, and 18mm internal and external corner welds, as well as diamond, zigzag, and I-shaped surfacing welds.
2. To address large manufacturing errors in conveying channels, irregular shapes, and severe wear during factory repairs, we employ a teaching method to locate the welding track, significantly reducing the precision requirements for workpiece positioning. Once the workpiece is hoisted onto the worktable and the start and stop points of the teaching welding track are set, welding can begin. For multi-layer and multi-pass weld buildup, only the first weld seam needs to be taught, and for surfacing welds, only the starting points of the polygonal shape need to be taught, saving a substantial amount of teaching time compared to teaching each weld seam for a six-axis robot. A common surfacing pattern library is available, allowing for direct retrieval of patterns for welding specific shapes. The welding process library is comprehensive, enabling direct parameter retrieval, matching the welding track offset, welding speed, current, and voltage, with simple operation.
3. Large span, accommodating 6 sets of workpieces at once, featuring a foldable dual water-cooled welding torch, multi-layer multi-pass welding, which boosts efficiency by approximately 30% compared to traditional equipment. Welding 12mm corner joints, 19-22 pieces can be produced in 12 hours, significantly exceeding the 13-15 pieces of traditional equipment.

Some specialized machines support various welding processes such as flat welding and chipping welding, and can also be operated through a multi-axis CNC system and teaching positioning function.Based on the development of a nine-axis CNC system, the functionality can be expanded at any time according to process requirements. Multi-functional, covering common welds on the central groove, such as12mm, 15mm, and 18mm internal and external corner welds, as well asDiamond, zigzag, and I-beam complex welds.
Precision Control:The CNC system precisely controls welding parameters, ensuring the welds are aesthetically pleasing and uniform. Some specialized machines are equipped with fully automatic positioners, enabling stable flipping of large middle slots, facilitating multi-angle and all-around welding.
Simple operation:For输送槽manufacturing with large tolerances, irregular shapes, and severe wear during repair, the teaching method is used to locate the welding path, significantly reducing the precision requirements for part positioning. Once the part is hoisted onto the worktable and the start and end points of the teaching welding path are set, welding can begin. For multi-layer, multi-pass surfacing, only the first weld seam needs to be taught, and the starting points of the surfacing paths are taught for polygons. This saves a substantial amount of teaching time compared to teaching each seam on a six-axis robot. A common surfacing pattern library is available, allowing direct retrieval of patterns for welding specific shapes. The welding process library is comprehensive, enabling direct retrieval of library parameters, matching the weld path offset, welding speed, current, and voltage, with simple operation.
