Description

Technical Field

[0001] This invention relates to the field of threaded steel cutting technology, and more specifically, to a threaded steel cutting device with an auxiliary fixing structure. Background Technology

[0002] Rebar is widely used in construction, bridges, and infrastructure projects. Before construction, it needs to be cut to a fixed length according to the design dimensions. Rebar cutting equipment has become a common processing tool in rebar processing plants and construction sites. Currently, conventional rebar cutting equipment on the market mainly relies on a simple stop block on one side of the blade for limiting movement, lacking a supporting auxiliary fixing structure. Rebar has continuous ribs on its surface and high material hardness. Under the shearing impact of the blade, the rebar is prone to radial rotation, axial slippage, and vertical jumping at the end. Rebar displacement will cause large errors in the cutting length, uneven cut surfaces, and an increased rate of defective products.

[0003] When cutting long-gauge rebar, most operations rely on manual hand-holding to stabilize the material. This is not only labor-intensive, but also poses a significant safety hazard as the operator's hands are close to the cutting edge. Furthermore, traditional fixed structures have limited adjustment methods, making it difficult to adapt to the simultaneous processing of rebar of various diameters. The continuous transmission of shearing vibrations can accelerate blade wear and shorten tool life. Existing cutting devices lack flexible and adaptable auxiliary positioning and clamping mechanisms, making it difficult to balance cutting accuracy, operational safety, and the processing needs of multiple material specifications.

[0006] The present invention is further configured such that two slide rails are installed on the motherboard, and the two slide rails are respectively connected to two cutting blades to restrict the position of the cutting blades and improve the smoothness and accuracy of the device.

[0007] The invention is further configured such that a bearing is provided on the lower fixed plate, a lifting screw is fitted on the bearing, and a lifting knob is installed on the upper fixed plate. The lifting knob and the lifting screw are installed together to make the upper fixed plate rise and fall smoothly, thereby improving the stability of the device.

[0009] The present invention is further configured such that a conveying motor is installed on one of the conveying rollers to provide power to the material conveying mechanism.

[0010] The invention is further configured such that the material processing cart includes a collection box, pulleys and a mounting frame, the mounting frame is installed at the bottom of the cart, the pulleys are installed on the mounting frame, and after the rebar is cut, it enters the material processing cart via a conveyor belt, thereby improving the smoothness of the device's operation.

[0011] The invention is further configured such that a strong magnet is provided on the side of the collection box near the conveyor belt, and the base is an iron base, which facilitates the fixing of the material cart and the base and saves costs.

[0012] The present invention is further configured such that the base is provided with an anti-corrosion coating, which is prepared by weight of 10-20 parts sodium fluoride, 5-10 parts ammonium bifluoride, 10-15 parts potassium permanganate, 10-20 parts potassium chromate, 5-10 parts zinc phosphate, 5-18 parts sodium nitrate, 5-12 parts praseodymium chloride, 10-16 parts ethylenediaminetetraacetic acid, 5-12 parts sodium dodecylbenzene sulfate, 5-13 parts nickel sulfate, 5-10 parts triethanolamine, 5-10 parts nickel chloride, 5-12 parts boric acid, 5-8 parts saccharin, 5-12 parts brightener and 50-70 parts water.

[0013] The present invention is further configured such that the anti-corrosion coating is prepared by weight of 10 parts sodium fluoride, 5 parts ammonium bifluoride, 10 parts potassium permanganate, 10 parts potassium chromate, 5 parts zinc phosphate, 5 parts sodium nitrate, 5 parts praseodymium chloride, 10 parts ethylenediaminetetraacetic acid, 5 parts sodium dodecylbenzene sulfate, 5 parts nickel sulfate, 5 parts triethanolamine, 5 parts nickel chloride, 5 parts boric acid, 5 parts saccharin, 5 parts brightener, and 50 parts water. Beneficial effects

[0014] Compared with the prior art, the present invention provides a cutting device for processing threaded steel bars with an auxiliary fixing structure, which has the following beneficial effects: The cutting mechanism drives the transmission rod through the transmission roller, which in turn drives the cutting blade to move on the slide rail. The cutting blade moves back and forth in a straight line along the slide rail, limiting the deviation of the cutting blade, ensuring the accuracy of the cutting blade's running trajectory, effectively preventing the blade from shaking during the cutting process, resulting in a flat cutting surface and improving the dimensional accuracy of the rebar cutting. The transmission rod performs power reversal transmission, and the transmission path is reasonably arranged to ensure that the power is smoothly delivered to the cutting blade.

[0015] The auxiliary fixing assembly secures the threaded steel bar through the cooperation of an upper and lower fixing plate. The groove in the upper fixing plate is deeper than the opening of the groove in the lower fixing plate. The coordination of the lifting knob, lifting screw, and lifting motor ensures precise and stable fixing of the threaded steel bar. The shallow groove in the upper fixing plate provides downward pressure and constraint, preventing the threaded steel bar from jumping upwards during the shearing process and effectively preventing rotation and displacement. This structure provides stable clamping, ensuring cutting accuracy and a flat cut end. It is adaptable to various specifications of threaded steel bar, eliminating manual support, removing safety hazards, and features a simple structure, flexible lifting adjustment, and convenient maintenance.

[0016] 3. The material conveying mechanism, through the cooperation of conveyor belt, conveyor roller, conveyor motor, material cart, and strong magnet, enables the rebar to be transported to the end by the conveyor belt, conveyor roller, and conveyor motor after cutting, and fall into the material cart for collection, reducing the amount of manual handling; buffering the impact of material feeding and protecting the quality of the rebar ends; at the same time, suppressing the slippage and collapse of rebar during the material cart transfer, improving the automation level of continuous cutting operations and on-site production safety, ensuring that the material is always constrained within the material cart range, and reducing the risk of mechanical injury and equipment jamming failure.

The material conveying mechanism includes a conveyor belt 12 and a conveyor roller 13, which are connected to the conveyor belt 12. The conveyor roller 13 is mounted on the base 1.

[0023] In a further embodiment of this application, two slide rails 14 are installed on the motherboard, and the two slide rails 14 are respectively connected to two cutting blades 3 to restrict the position of the cutting blades 3 and improve the smoothness and accuracy of the device.

[0024] More specifically, in this embodiment, when the device is needed, the cutting mechanism drives the drive gear 6 to rotate via the motor 8, and the drive gear 6 meshes with the driven gear 7, thereby driving the driven gear 7 to rotate, which in turn drives the linkage roller 5. Through the linkage of the transmission rod 4, the linkage roller 5, the slide rail 14 and the cutting blade 3, the cutting blade 3 is limited to move on the slide rail 14, thereby achieving the cutting of the threaded steel.

[0025] In a further embodiment of this application, a bearing 15 is provided on the lower fixed plate 9, and a lifting screw 16 is sleeved on the bearing 15. A lifting knob 17 is installed on the upper fixed plate 10. The lifting knob 17 and the lifting screw 16 are installed together to make the upper fixed plate 10 rise and fall smoothly and improve the stability of the device.

[0026] In a further embodiment of this application, a lifting motor 18 is installed on the top of the lifting screw 16, making it easier for workers to operate the device.

[0027] More specifically, in this embodiment, when the device is needed, the threaded steel to be cut is first placed on the lower fixed plate 9, and then the lifting screw 16 is driven by the lifting motor 18 to rotate in conjunction with the bearing 15. Then, the upper fixed plate 10 is raised and lowered by cooperating with the lifting knob 17. Finally, the upper fixed plate 10 is fixed by cooperating with the lower fixed plate 9.

[0028] In a further embodiment of this application, a conveyor motor 19 is mounted on one of the conveyor rollers 13 to provide power to the material conveying mechanism.

[0029] In a further embodiment of this application, a material collection cart is placed at the tail of the conveyor belt 12.

[0030] In a further embodiment of this application, a strong magnet 23 is installed on the collection box 20, and the base 1 is an iron base, which facilitates the fixing of the material cart and the base 1 and saves costs.

[0031] More specifically, in this embodiment, when the device is needed, the conveyor motor 19 provides power to the conveyor roller 13 so that the conveyor belt 12 transports the cut rebar.

Through the linkage of the transmission rod 4, the linkage roller 5, the slide rail 14 and the cutting blade 3, the cutting blade 3 performs a limited movement on the slide rail 14, thereby achieving the cutting of the threaded steel.

[0034] The conveyor motor 19 provides power to the conveyor roller 13 so that the conveyor belt 12 transports the cut rebar. The rebar is transported to the end of the conveyor belt 12 and enters the collection box 20 through the action of the conveyor belt 12 and the strong magnet 23. After the cutting operation stops, the finished rebar can be transported over a short distance by manually pushing the material cart.
