Dismounting and mounting device for punching sleeve

Abstract

The invention relates to a dismounting and mounting device for a punching sleeve. The dismounting and mounting device comprises a supporting seat, a sleeve pulling rod and a lifting adjusting structure; the supporting seat comprises two vertical supporting legs arranged oppositely and a transverse beam fixed on the vertical supporting legs, the sleeve pulling rod is vertically installed in the transverse beam and located between the two vertical supporting legs, and the lifting adjusting structure can adjust the lifting motion of the sleeve pulling rod in the transverse beam; a bearing rod capable of rotating is further installed at the lower end of the sleeve pulling rod, and the rotation axis of the bearing rod is perpendicular to the sleeve pulling rod; the sleeve pulling rod is used for penetrating through the punching sleeve; and when the bearing rod rotates to be transverse, two ends of the bearing rod stretch out of the side wall of the sleeve pulling rod to abut against the lower end of the punching sleeve, and the two ends of the bearing rod do not stretch out of the side wall of the punching sleeve. The dismounting and mounting device is simple in structure and convenientto use, can be used in a narrow working space, and can guarantee the dismounting and mounting quality of the punching sleeve and improve the dismounting and mounting work efficiency.

Description

technical field [0001] The invention relates to the field of mechanical maintenance, in particular to a disassembly and assembly device for punching sleeves. Background technique [0002] At present, in the production of cold-rolled disilicon steel, the main equipment for continuous annealing is generally made in Japan and Germany, and the precision of related equipment is relatively high. At present, the strip steel welding machine is imported equipment, and the parts of the original imported equipment are replaced by localized production. During the process, some parts and components have some deviations from foreign processing dimensional accuracy, which makes it difficult for the maintenance personnel to disassemble and assemble the punching sleeve. Because the punching sleeve equipment has a small space in front of the welding machine, the tool is also inconvenient to use. Every time the punching sleeve is replaced Hole sets need more than 30 minutes, thus affecting the...

[0002] At present, in the production of cold-rolled disilicon steel, the main equipment for continuous annealing is generally made in Japan and Germany, and the precision of related equipment is relatively high. At present, the strip steel welding machine is imported equipment, and the parts of the original imported equipment are replaced by localized production. During the process, some parts and components have some deviations from foreign processing dimensional accuracy, which makes it difficult for the maintenance personnel to disassemble and assemble the punching sleeve. Because the punching sleeve equipment has a small space in front of the welding machine, the tool is also inconvenient to use. Every time the punching sleeve is replaced It takes more than 30 minutes for the hole sleeve, which affects the continuity of silicon steel production

In the past, the punching sleeve of the welding machine and the machine body were imported parts, which were high-precision and could be disassembled and replaced with only a screwdriver. , making it very difficult to replace the punching hole each time
