Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the utility model will be further described:

[0022] Such as figure 1 As shown in the figure, a device for correcting the bulging waist deformation of a rolled cylindrical body includes two symmetrical arc-shaped parts 1, an adjusting bolt 3 and a working bolt 4. It is characterized in that there are lugs 2 on the top of the two arc-shaped parts 1, The lower part of the lug 2 has a connecting piece 8, and the upper part of the lug 2 has an adjusting bolt hole; the two arc-shaped parts 1 are hinged through the connecting piece 8 at the lower part of the supporting lug 2 to form a pincer structure; the adjusting bolt 3 passes through two The bolt holes on the lugs 2 can change the angle between the two arc parts 1 by adjusting the nuts on the adjusting bolts 3; there are working bolts 4 on the top of the two arc parts 1, and the working bolts 4 are arranged along the The radial direction of the arc component 1 passes throu...

Abstract

The invention belongs to the field of manufacturing of machinery, in particular to a method and device for correcting drum waist deformation during rolling of a cylindrical body. The device comprises two symmetrical arc-shaped components, an adjusting bolt and a working bolt, wherein the symmetrical arc-shaped components are hinged with each other through a connecting sheet to form a clamp-shapedstructure. The correcting method comprises the following steps of: sleeving the device into the cylindrical body, wherein the opening of the cylindrical body faces the hinged position of the two arc-shaped components; making the two arc-shaped components cling to the cylindrical body by adjusting a nut on the adjusting bolt; and applying pressure to the drum waist deformation position of the cylindrical body opening by adjusting the screwing depth of the working bolt to restore the drum waist position to a designed size. By adopting of the method and the device, the drum waist deformation during rolling of the cylindrical body is corrected in a semi-mechanical way instead of a purely manual knocking way, so that the workpiece size can be recovered accurately, the workpiece welding qualityis improved, the labor intensity of workers is lowered, the production efficiency is increased, noise pollution is avoided, and a good effect is achieved.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a method and a device for correcting the bulging waist deformation of a rolled cylindrical body. Background technique [0002] In the machinery manufacturing industry, uneven butt welds are common in the process of rolling cylindrical products by plate rolling machines. After the welding points at both ends of the rolling drum body are fixed, there are quality problems such as bulging waist, excessive gap, and uneven joint in the middle. In view of such situations, operators generally use hand hammers and some auxiliary tools to solve the problem, but this method requires high technical skills for workers, and the production noise is high, labor intensity is high, production efficiency is low, and the correction effect is not ideal. Affect welding quality. It has been a long-standing technical quality problem in rolling cylindrical bodies. Contents of the i...
