Detachable riveting gun barrel

Abstract

The invention discloses a detachable riveting gun barrel which includes a gun barrel body, wherein the gun barrel body includes a first section of the gun barrel, a plurality of middle sections of the gun barrel and an end section of the gun barrel; connecting blocks that can be matched with each other are arranged on the left side or the right side of the connecting ends of two adjacent sections; pin holes are correspondingly formed in the two connecting blocks connected in a matched manner; two half pins with the same diameter and different lengths are correspondingly mounted in the pin holes and are both connected with the pin holes in an interference fit manner; the connecting blocks at the two ends of each middle section are arranged opposite to each other. The detachable riveting gun barrel provided by the invention is simple in structure, easy to manufacture, flexible and convenient to adjust the length of the gun barrel, wide in application range, and stable in connection between sections without rotation, and the effective transfer of the acting force is facilitated.

Description

technical field [0001] The invention relates to the technical field of rivet guns, in particular to a detachable rivet gun shaft. Background technique [0002] Rivet guns are used for fastening and riveting of various types of metal sheets, pipes and other manufacturing industries. At present, they are widely used in the riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decorations, etc. . Developed to solve the shortcomings of metal sheets and thin tubes that weld nuts are easy to melt, and internal threads are easy to slip. It can rivet riveting products that do not require internal thread tapping or welding nuts. The riveting is firm and efficient, and it is convenient and quick to use. [0003] Rivet guns are divided into pneumatic rivet guns, electric rivet guns, manual rivet guns, and hydraulic rivet guns according to different powers. The manual cap-pull gu...

AI Technical Summary

Problems solved by technology

Yet the gun shaft of existing manual pull cap gun such as Figure 4 As shown, they are all single structures that cannot be disassembled and have a fixed length. This gun shaft structure has the following defects: the length of the gun shaft is too short, and when riveting, it takes a lot of force to drive the rivets at the joint; the length of the gun shaft is long, and the rivets The gun is difficult to rivet in a narrow place, or even unusable, resulting in a small range of use, and the longer gun barrel is heavier, which increases the strength of riveting
