Flange bolt press-fit tool and working method thereof

Abstract

The invention discloses a flange bolt press-fit tool and a working method thereof. The flange bolt press-fit tool comprises an upper press-fit stamping head capable of reciprocating up and down to conduct stamping operation, a flange plate fixing lower die base arranged below the upper press-fit stamping head, and a lower die base fixing base arranged at the bottom of the flange plate fixing lower die base. The flange plate fixing lower die base is provided with a flange plate center positioning protruding block used for fixing the position of a flange plate, and a flange bolt press-fit through hole used for placing a flange bolt. A flange bolt motion positioning sleeve is arranged in the flange bolt press-fit through hole. A bolt coaxial limiting mounting groove is formed in the upper end of the flange bolt motion positioning sleeve. A positioning sleeve reset spring is arranged between the lower end of the flange bolt motion positioning sleeve and the lower die base fixing base. By arranging the flange bolt motion positioning sleeve and the positioning sleeve reset spring, the flange bolt press-fit tool has the characteristics that the working efficiency is high, and the flange bolt and a flange plate bolt hole are not liable to be deformed due to stress.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment and its working method, in particular to a flange bolt pressing tool and its working method. Background technique [0002] The traditional flange connection bolts are usually movable on the flange plate. When the flanges with conventional movable bolts are used to realize the fixed connection of pipelines or parts, it is usually necessary to fix the bolts first so that the position is fixed and there will be no accidents. Rotate, and then use fasteners such as nuts to fix the bolts and the flanges connected to them with the pipelines to be connected or the fixed installation positions. For some locations where the installation space is small, it is not convenient to set additional tools such as wrenches to fix the position and rotation angle of the flange bolts, so the flange bolts need to be fixed together in advance, so as to facilitate the installation and fixing of the ...

AI Technical Summary

Problems solved by technology

For some locations where the installation space is small, it is not convenient to set additional tools such as wrenches to fix the position and rotation angle of the flange bolts, so the flange bolts need to be fixed together in advance, so as to facilitate the installation and fixing of the flange plate; Usually the flange bolts are pre-fixed together mainly by welding, but the shortcomings of the welding fixation method are: on the one hand, the efficiency of the flange bolt connection operation is low, and on the other hand, it is difficult to guarantee the connection and fixation by welding. The coaxiality between the bolt and the bolt hole of the flange, the high temperature when welding again makes the flange and the bolt easy to deform when heated, thus affecting the sealing and stability of the flange connection and fixing

Based on the above problems, the present invention proposes a way to connect and fix the bolts and flanges through interference fit. However, the interference fit of conventional flange bolts is less efficient, and it is easy to cause the bolts to deform under force, or make the The bolt holes of the flange are deformed under stress, so it is necessary to provide a flange bolt pressing tool and its working method to overcome the above-mentioned problems in the prior art
