Embodiment

[0019] A tool for removing rivet heads and heading heads, comprising a working part 1, a transition part 2 and a shank part 3, the working part 1, the transition part 2 and the shank part 3 are connected in sequence, and the developed length is 135mm.

[0020] The working part 1 and the transition part 2 form a bending angle of 10°, and the bending angle is at a radius R=20mm; The length of the straight line on the surface is l=7mm, the surface roughness is 0.8, and the length of the front end of the working part 1 is l 1 = 7mm; the front and back of the main view of the working part 1 form an angle of 60°;

[0021] figure 2 , image 3 and Figure 4 They are the A-direction, B-direction and C-direction views of the working part 1, wherein there is a section of the working part in the A-direction view, where the working width is b=5mm and the working length is l 2 = 4mm; in the view of direction A, it can be seen that the cutting edge of the special tool for removing rivet...

Abstract

The invention belongs to the technical field of machining tools, and provides a tool for removing a rivet head and an upset head from a rivet. The tool is formed by connecting a working part, a transitional part and a tail shank part in sequence. The working part and the transitional part form a bent angle of 10 degrees; the front end of the working part is of a slope shape; the slope and the axial line of the working part form an angle of 25 degrees; the straight length of the slope is 7 mm; the front end of the working part is 7 mm in length; the front part and the rear part of the working part form angles of 60 degrees; the width of the cutting edge of the working part is equal to the diameter of the rivet to be removed; the diameter of the transitional part is equal to that of the rear end of the working part; the tail shank part is in fit connection with the transitional part; and the tail shank is held in a hand. The tool for removing the rivet head and the upset head from the rivet can quickly and conveniently remove disqualified rivets and is extremely high in removal rate, convenient to use and time-saving, and the production efficiency of a worker is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of processing tools and relates to a tool for removing rivet heads and upset heads. Background technique [0002] In the field of aviation assembly, whether it is a civil aircraft or a military aircraft, various skeletons and skins are often riveted with rivets, or skins are riveted between skins. The protruding height of the rivet head and the quality of the rivet head directly affect the surface quality of the aircraft. Because the quality of the outer surface of the aircraft directly affects the aerodynamic shape of the aircraft. The riveting quality of the rivets is very important. In aircraft assembly, it is often necessary to remove some rivets with poor nail head quality and heading quality. Therefore, it is necessary to design a special tool for removing rivets. [0003] In the process of aircraft assembly and production, due to many factors such as the operator's skill level, operating level, and...
