Description

Technical Field

[0001] This utility model relates to the technical field of steel bar processing equipment, specifically to a tooling that can adsorb and treat dust generated during the processing of steel bars before welding. Background Technology

[0002] Before assembling and welding the planar steel mesh, precast beam processing plants need to straighten and cut the steel bars to a fixed length. Currently, commonly used processing equipment includes the GT5-14 type integrated steel bar cutting and straightening machine. However, operators have found that during continuous production and processing, a large amount of iron filings and other dust accumulates at the bottom of the machine. This dust adheres to the steel bars when they rub against the straightening equipment and is shaken off when the steel bars are cut at the discharge port. This dust not only affects the health of operators but also pollutes the working environment within the plant. How to handle this dust has become a major problem. Utility Model Content

Preferably, The beneficial effects of this utility model are: This utility model uses a planar frame and legs to form an integral support, which can reliably support the integrated rebar cutting and straightening machine. The slider and auxiliary support rod of the first positioning component allow the guide plate to move along the guide rod, making it easy to adjust its position according to actual processing needs. The second positioning component, through the combination of a locking block, an auxiliary support plate, and male and female buckles, not only enhances the installation stability of the guide plate but also facilitates disassembly and maintenance, improving the practicality and flexibility of the tooling. Furthermore, by placing one end of the guide plate below the discharge port of the integrated rebar cutting and straightening machine, it can receive and guide the dust shaken off during rebar cutting, allowing the dust to slide smoothly down the guide plate to the negative pressure recovery device for collection and treatment. In addition, the trapezoidal guide plate structure, which is wider at the top and narrower at the bottom, along with the limiting plates on both sides, can further prevent dust from spilling out. The extension extends into the feed window of the negative pressure recovery device. Together with the negative pressure system consisting of the buffer pipe, air pipe, collection chamber, and fan, it can quickly suck dust into the collection chamber, achieve effective dust collection, avoid dust accumulation in the processing area, and greatly improve the working environment. This invention can effectively reduce the harm of dust to operators, lower the risk of respiratory diseases and other health problems caused by dust inhalation, and protect the health of workers.
