Bottom shell and welding seam assembly tool structure for electromagnetic chuck for hoisting and transporting wheel steel ingots and repair process for bottom shell and welding seam assembly tool structure

Abstract

The invention discloses a bottom shell and welding seam assembly tool structure for an electromagnetic chuck for hoisting and transporting wheel steel ingots and a repair process for the bottom shelland welding seam assembly tool structure. The tool structure comprises a circular bottom shell and an upper cover panel welded on the bottom shell, and further comprsies a welding gun, wherein a jointof the circular bottom shell and the upper cover panel defines a welding seam; a plurality of upper fixing devices are uniformly arranged on the upper surface of the upper cover panel; each upper fixing device is connected to a hoisting ring through a connecting chain; a plurality of hook head clamps are uniformly arranged along the periphery on the bottom shell and the upper cover panel; each hook head clamp comprises a hook head clamp body in the shape of U with an opening facing leftwards, the upper part and the lower part of the hook head clamp body are separately a hook head upper clamping plate and a hook head lower clamping plate, and a distance between the hook head upper clamping plate and the hook head lower clamping plate is equal to sum of height of the bottom shell and heightof the upper cover panel; a wire hole is formed in the hook head upper clamping plate; and a full-thread bolt which is adaptive to the wire hole is arranged in the wire hole. The bottom shell and welding seam assembly tool structure disclosed by the invention can perform online welding repair for fracture of the bottom shell on the electromagnetic chuck, saves maintenance time, reduces maintenance cost, reduces breakdown loss, and provides guarantee for reasonable assembly and production.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a welding seam assembly structure and a repairing process of an electromagnetic sucker bottom shell of a hoisting wheel steel ingot. Background technique [0002] The electromagnetic chuck is an electromagnetic fixture, which fixes the workpiece through the suction force generated by the chuck body after the electromagnetic coil is energized. The electromagnetic chuck consists of: bottom shell, iron core, coil, panel and junction box. The coil is fixed around the iron core, the bottom shell is welded on the bottom surface of the iron core to form the ring weld between the middle of the bottom shell surface and the iron core, and the outer ring weld 8 of the joint welding of the bottom shell and the panel cover, and the panel is welded on the iron core On the above, the junction box is connected and fixed on the panel to form an integral structural member electromagnetic chuc...

AI Technical Summary

Problems solved by technology

The steel ingots of various specifications required for mass production every day are naturally dropped to the surface of the steel ingot through the electromagnetic chuck according to the design process requirements. The steel ingot is fixed by suction through the iron core and the bottom shell that is fixed and welded together. Due to the lifting work in the actual material yard, there are sometimes: 1. The lifting position of some steel ingots is offset, and the electromagnetic sucker must be used when lifting various wheel steel ingots. Impacted by the outside of the bottom case

2. The operator moves up and down when operating the electromagnetic sucker to lift various wheel steel ingots, causing the iron core that comes from the suction force and the one-piece fixed and welded bottom shell to directly hit the contact surface of the wheel steel ingots

However, with the passage of time, partial and overall cracking and desoldering of the outer girth weld of the bottom shell and panel cover joint welding will occur. If it is not repaired in time, partial and overall cracking of the outer circular weld of the bottom shell will occur. The desoldering part will damage the main coil through the combination of damage and cracking, which will affect the overall electromagnetic chuck without any suction force, which will inevitably affect production. Direct replacement of new spare parts will cost a lot, and it will take a long time to ship it to the manufacturer for repair. , in order to resume production as soon as possible, it is necessary to repair the welding fracture of the bottom shell on site
