Description

Technical Field

[0001] This utility model relates to the technical field of steel bar processing equipment, specifically to an integrated automatic rust removal and straightening device for steel bar processing. Background Technology

[0002] As a core basic material in fields such as building construction, bridge construction, and machinery manufacturing, the surface cleanliness and straightness of steel bars directly determine the bond strength of concrete, the load-bearing capacity of the structure, and the accuracy of subsequent processing. During the production, storage, and transportation of steel bars, the surface is prone to forming a rust layer due to the influence of environmental humidity and oxidation.

[0003] A search revealed that Chinese Patent No. CN221790867U discloses a rust-removing rebar straightening device, which includes a rebar straightening machine. The feed end of the rebar straightening machine is equipped with a rust-scraping and oiling structure, which includes a front scraping section, an oiling section, and a rear scraping section arranged sequentially along the delivery direction of the rebar.

[0004] Traditional rust removal equipment lacks pretreatment of the rust layer before rust removal, and directly uses mechanical grinding or sandblasting to remove rust. It is difficult to completely remove stubborn rust layers, and the energy consumption during the rust removal process is high. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned shortcomings and defects of the existing technology in that it is difficult to completely remove stubborn rust layers.

With the design of multi-roller gradual straightening channel and wear-resistant rubber layer, it not only ensures the accuracy and stability of rebar straightness calibration, but also improves processing efficiency through the continuous process of pretreatment and mechanical rust removal. The dual-nozzle structure separated by partitions in the auxiliary box can realize continuous operation of rust removal liquid pretreatment and clean water cleaning. The observation window design of water tank and liquid storage tank facilitates real-time monitoring of liquid level, further optimizing the convenience of processing flow and the cleanliness of rebar surface, ensuring the subsequent concrete bonding strength and structural load-bearing capacity.

[0022] See Figure 4 , Figure 5 As shown, a flow regulating valve 803 is installed between the delivery pipe 801 and the auxiliary box 3. The flow regulating valve 803 is an electromagnetic flow regulating valve, which can precisely adjust the spray flow through the controller 16. A circulation component 10 is installed between the lower end of the auxiliary box 3 and the liquid storage tank 7. The circulation component 10 includes a return pipe 1001. One end of the return pipe 1001 is connected to the auxiliary box 3. The return pipe 1001 has the same specifications as the delivery pipe 801.

[0023] See Figure 2As shown, the other end of the return pipe 1001 is connected to the storage tank 7. A booster pump 1002 is installed between the return pipe 1001 and the storage tank 7. A partition 18 is fixedly installed inside the auxiliary box 3. The partition 18 is made of 304 stainless steel plate. A guide hole adapted to the diameter of the steel bar is opened in the middle of the partition 18. A wear-resistant nylon bushing is embedded inside the guide hole.

[0025] The implementation principle is as follows: During operation, one end of the steel bar to be processed is fed into the feed end of the steel bar straightening machine 2. Under the action of the conveying force, the steel bar passes through the straightening channel, and the bending deformation of the steel bar is gradually corrected. The straightened steel bar is continuously conveyed towards the auxiliary box 3. The steel bar enters the pre-treatment area on one side of the partition 18 inside the auxiliary box 3. The booster pump 802 conveys the rust removal liquid in the storage tank 7 to the nozzle 6 through the conveying pipe 801. The flow regulating valve 803 precisely controls the spraying flow rate. The nozzle 6 sprays the rust removal liquid evenly onto the surface of the steel bar to soften the stubborn rust layer formed by long-term storage, reducing the difficulty of subsequent mechanical rust removal. After spraying, the waste liquid carrying some loose rust residue drips down to the filter assembly 9 below. After the filter screen 902 intercepts large rust residue, the activated carbon adsorption layer 903 adsorbs impurities, and the precision filter membrane 904 filters fine particles, the booster pump 1002 pumps the filtered rust removal liquid back to the storage tank 7 through the return pipe 1001, realizing the recycling of the rust removal liquid. The steel bars, after being pretreated with rust remover, pass through partition 18 and enter the cleaning area on the other side of auxiliary box 3; When the second conveying component 13 is activated, it delivers clean water from the water tank 12 to the second nozzle 11. The second nozzle 11 sprays clean water onto the surface of the steel bar to rinse away any residual rust remover and small rust residue that has not yet been removed. The cleaning waste liquid drips onto the second filter component 14, and after being filtered through multiple layers, it is pumped back to the water tank 12 through the second circulation component 15 for recycling, ensuring that there are no chemical residues on the surface of the steel bar. The cleaned steel bars are continuously conveyed to the rust removal machine 4, which is a wire brush roller type rust removal machine. Under the action of the roller rotation, the rust layer softened by the rust removal liquid is deeply polished to thoroughly remove stubborn rust. At the same time, the oxide scale and impurities on the surface of the steel bars are removed. The rust-removed steel bars are output from the discharge end of the rust removal machine 4. After the processing is completed, the power components of the equipment are turned off. After the liquid circulation system stops running, the main power supply is turned off.
