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

Abstract

The invention discloses a production system for steel structure fixed fasteners of engineering auxiliary facilities, including a moving system, a slotting system, a clamping system, a hole opening system, an assembly system, and a high-temperature system arranged above the moving system; the production system of the invention It can produce fasteners with multiple functions. On the one hand, it can increase production capacity and reduce costs. On the other hand, the production process is scientifically processed. The slotting system uses three components and three-stage slotting. The slotting process does not penetrate the raw materials, which is not easy to cause damage. Raw material damage, the production system of the present invention simultaneously performs cooling liquid spraying and air blowing to cool down the auxiliary means of cold treatment during the slotting and drilling process, on the one hand, it can effectively avoid the occurrence of damage to the raw material, on the other hand, it can remove the damage in the processing process. A large amount of chip residue is generated to improve machining accuracy.

Description

technical field [0001] The invention relates to the technical field of fixed fastener production equipment, in particular to a production system and a recycling method for a steel structure fixed fastener of engineering auxiliary facilities. Background technique [0002] With the rise of the infrastructure boom, a large number of civil and earthwork projects have been carried out, among which the steel structure fixing fasteners of engineering auxiliary facilities are an indispensable and hugely used consumable. The quality of the fastener itself determines whether the platform or frame it carries 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 Construction", it is proposed that the design value of the anti-slip bearing capacity of the butt-joint fasteners should be higher than 3.2kN, and the anti-slip bearing capacity of the right-angle fasteners and the ...

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
