Embodiment Construction

[0031] Now in conjunction with accompanying drawing and embodiment the present invention is further described:

[0032] Combining the shortcomings of the currently used rivet removal tools, a more reasonable rivet removal tool was redesigned. After the formulation of the design plan, drawing of drawings, and process arrangement, the entire content of the design part was completed, which is the next step for the production of the real object Foundation.

[0033] As shown in the figure: 1 pick knife; 2 fixed sleeve; 3 positioning slider; 4 screw; 5 movable riveting head; 6 spring; 7 guide washer; 8; static riveting die; Hydraulic cylinder; 13 piston rod; 14 mounting holes; 15 rivets; 16 static rivet head mounting holes.

[0034] The rivet removal tool includes a removal knife, a fixed sleeve, a positioning slider, a dynamic riveting head, a guide washer, a static riveting die, a static riveting head, and a spring. According to the cooperation with the riveting pliers, it is di...

Abstract

The invention provides a rivet removing tool and method. No special tool for removing skew rivets is available at present, rivet heads are removed with a sledge hammer by workers through a self-made tool, then rivet rods are ejected out by means of a sharp tool, the risk is extremely high, and a large number of industrial accidents are caused. A hydraulic station of a field riveting machine is used for supplying power to the rivet removing tool, and the rivet removing tool comprises a removing knife, a fixing sleeve, a positioning sliding block, a movable rivet head, a guide washer, a fixed rivet mold, a fixed rivet head and a spring. The removing knife is clamped in the positioning sliding block and makes contact with a rod of a rivet. The fixed rivet head is fixed to the other end of a rivet clamp. The fixed rivet mold is used for fixing a cap of the rivet. The rod of the rivet is removed out of an inner cavity of the fixed rivet head by applying force through a hydraulic piston rod and then taken out after being clamped. The removing knife is made of a high-strength high-plasticity material and can meet the requirements for hardness and the like, and thus the effect that the rivet removing tool is prevented from being broken in the use process is guaranteed. By the adoption of the rivet removing tool, the effect is quite remarkable, and skew rivets and redundant rivets can be removed rapidly and conveniently.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a special device for removing rivets. Background technique [0002] At present, in the production workshop, there are no special tools for removing skewed, mis-riveted, and multi-riveted rivets. When removing these rivets, workers use self-made rivet removing tools, use a sledgehammer to remove the rivet head, and then remove the rivet rod with a sharp tool. ejected. During the removal operation, sometimes the rivet head will fly out, the speed is high, the risk is extremely high, and the labor intensity is high, which has caused many industrial accidents. Contents of the invention [0003] Aiming at the above technical problems to be solved, a rivet removal tool and method thereof are provided. [0004] The design idea of ​​the multifunctional special tool for removing rivets of the present invention is ingenious, it can make full use of the hydraulic power provided by the hydraulic s...
