Production system for engineering auxiliary facility steel structure fixing fasteners and recycling method

Abstract

The invention discloses a production system for engineering auxiliary facility steel structure fixing fasteners. The production system comprises a moving system, a grooving system, a clamping system, a hole forming system, an assembling system and a high-temperature system arranged above the moving system. According to the production system, fasteners with multiple functions can be produced, on one hand, the productivity can be improved, the cost can be reduced, on the other hand, the machining mode in the production process is scientific, the grooving system adopts three-component and three-section grooving, raw materials are not penetrated in the grooving process, and the raw materials are not prone to being damaged; and by means of the production system, in the grooving and hole forming operation processes, cooling liquid spraying and blowing cooling cold treatment auxiliary means are carried out at the same time, on one hand, the situation that raw materials are internally damaged can be effectively avoided, on the other hand, a large number of chippings and residues generated in the machining process can be removed, and the machining precision is improved.

Description

technical field [0001] The invention relates to the technical field of production equipment for fixed fasteners, in particular to a production system and a recycling method for steel structure fixed fasteners of engineering auxiliary facilities. Background technique [0002] With the rise of the infrastructure construction boom, a large number of civil and earthwork projects have been carried out, among which the steel structure fixing fasteners for engineering auxiliary facilities are an indispensable and extremely huge amount of consumables. The quality of the fastener itself determines whether the platform or frame it supports is safe and stable. For example, in the industry standard of the People's Republic of China "Safety Technical Specifications for Fastener Type Steel Pipe Scaffolding in Building Construction", it is proposed that the design value of the anti-sliding bearing capacity of the butt joint fasteners should be higher than 3.2kN, and the anti-sliding bearin...

AI Technical Summary

Problems solved by technology

[0003] (1) Most of the current production systems are mostly special production lines. For example, they can only produce fasteners with a single function, including butt fasteners, right-angle fasteners or bases. On the other hand, most of the production process adopts hard processing methods, such as penetrating drilling of raw materials, which has a high probability of causing a large amount of internal stress and damage to the raw materials.

At the same time, the fasteners produced can only be discarded as a whole after detection of problems, and cannot be partially replaced to achieve the effect of recycling again, which also greatly increases the cost of use

[0004] (2) The current mainstream production system seldom uses cold treatment auxiliary means when drilling and drilling raw materials. The residue and accumulation can easily cause the processing accuracy to drop, and it is easy to cause problems in the subsequent use process

[0005] (3) Most of the fasteners produced by the existing production system use the outer pipe wall and the hole wall to squeeze each other, and then fix them together by welding. This method is not only time-consuming and labor-intensive, but also causes a lot of pollution. Moreover, fatigue damage caused by long-term cyclic use is difficult to detect, and it is easy to bury hidden dangers of safety accidents

What is more critical is that machining errors will cause the above-mentioned extrusion to retain a large number of or large-scale gaps, resulting in false welding or virtual welding, and a low yield of fasteners
