Riveter head of titanium alloy ring groove self-plugging rivet pulling and forming riveter

Abstract

A pull riveting forming gun head for a titanium alloy ring groove self-plugging rivet (7) is composed of a shell (1), a driving rod (2), a spring (3), an ejector rod (4), a chuck (5) and an ejector pin (6). A driving rod (2) is arranged in the shell (1); a spring (3), an ejector rod (4) and a chuck (5) are sequentially arranged in the driving rod (2); and the ejector pin (6) is screwed into one side of the shell (1). The device is simple in structure and convenient to use; in the riveting process, the broken core rod does not clamp the gun head, and the newly-installed titanium alloy ring groove self-plugging rivet can eject the broken core rod out of the riveting gun, so that the riveting efficiency is improved.

Description

TECHNICAL FIELD

[0001] The utility model relates to a titanium alloy ring groove blind rivet pull rivet forming gun head belongs to the manufacturing technical field of mechanical processing parts. BACKGROUND

[0002] Titanium alloy ring groove blind rivet is a rivet of high strength, light weight and simple structure, is often used in the skin part of airplane and other aircraft, and the use frequency is high, demand is big, and the production of the product is frequent and the quantity is more.

[0003] Titanium alloy ring groove blind rivet needs to be riveted in the skin part by using special riveting tool when being used.

[0004] The rivet gun head of prior art not only has complex structure, but also the broken core rod is easy to be clamped in the gun head in the pull rivet process, and the riveting efficiency is low. UTILITY MODEL CONTENTS

[0005] The utility model solves the technical problem that the rivet gun head in prior art not only has complex structure, but also the broken core rod is easy to be clamped in the gun head in the pull rivet process, and the riveting efficiency is low.

[0006] In order to solve the above technical problem, the utility model adopts the following technical scheme:

[0007] A titanium alloy ring groove blind rivet 7 pull rivet forming gun head is composed of a shell 1, a driving rod 2, a spring 3, a top rod 4, a chuck 5 and a thimble 6.

[0008] The shell 1 is equipped with the driving rod 2;

[0009] The spring 3, the top rod 4 and the chuck 5 are sequentially arranged in the driving rod 2.

[0010] The thimble 6 is screwed into one side of the shell 1.

[0011] The beneficial effects of the above technical scheme are:

[0012] 1, the utility model has simple structure and is convenient to use.

[0013] 2, the broken core rod is not clamped in the gun head in the pull rivet process of the utility model, because the newly loaded titanium alloy ring groove blind rivet can push out the broken core rod from the rivet gun, thereby improving the riveting efficiency. DRAWING DESCRIPTION

[0028] The utility model will be further described in connection with the drawings as follows:

[0029] As Figure 3 Indicated, a titanium alloy ring groove core-pulling rivet 7 rivet forming gun head is formed by shell 1, drive rod 2, spring 3, ejector rod 4, chuck 5 and ejector pin 6;

[0030] The drive rod 2 is arranged in the shell 1.

[0031] The spring 3, the ejector rod 4 and the chuck 5 are sequentially arranged in the drive rod 2.

[0032] The ejector pin 6 is screwed into one side of the shell 1.

[0033] The working procedure of the utility model is as follows:

[0034] First step: in turn the chuck 5, spring 3, ejector rod 4 is installed in the drive rod 2, forms drive rod assembly, as shown in Figure 6 ;

[0035] Second step: drive rod assembly A is screwed into rivet gun 8 interface, and is tightened, as shown in Figure 7 ;

[0036] Third step: the needle 6 is screwed into the shell 1, forms shell assembly, then the shell assembly is screwed into the rivet gun 8 interface, as shown in Figure 8 ;

[0037] Fourth step: finally titanium alloy ring groove loosing core rivet 7 is installed in the gun head, riveting forming can be carried out, as shown in Figure 9 ;

[0038] The utility model (except spring) the material of each sub-piece adopts 60Si2MnA, and after quenching and tempering heat treatment, the hardness can reach HRC55~60, and finally surface treatment is oxidized blackening, can prevent corrosion and rust in the use process.
