[0003] Currently, rust removal on the surface of springs is a crucial step in ensuring their performance. Existing rust removal equipment typically uses acid pickling solution immersion for rust removal. However, the equipment has a low degree of automation, and the loading and unloading of springs during the rust removal process, as well as the transition from acid pickling to cleaning, largely rely on manual operation. This is not only inefficient but also poses a safety hazard as it can easily expose operators to harmful substances such as acids.

[0004] Therefore, we propose a rust removal device for spring surfaces. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Existing rust removal devices typically use acid pickling solution immersion for rust removal, but the devices have a low degree of automation.

[0013] As a preferred embodiment of this utility model, the pump body is used to transport the cleaning liquid inside the cleaning liquid storage tank to several spray nozzles through the connecting pipe, and spray it onto the spring surface located inside the hook component through several spray pipes. The discharge pipe is used to discharge the wastewater inside the spray tank to a designated location.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by setting up an up-and-down adjustment device (in conjunction with a vertical lead screw, a linear optical axis, and a drive motor) and a conveying structure (in conjunction with a horizontal lead screw and a rotary motor), the up-and-down movement of the hollow rust removal box and spring, as well as the lateral movement from the pickling tank to the rinsing structure, can be automatically realized.

[0028] Example

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a rust removal device for spring surfaces, including a gantry frame 1. First mounting grooves 2 are provided on both sides of the inner side walls of the gantry frame 1. An up-and-down adjustment device is provided inside the two first mounting grooves 2. A conveying structure is provided at the bottom of the up-and-down adjustment device. A hollow rust removal box 5 is provided at the bottom of the conveying structure. A hook 6 is provided at the top of the hollow rust removal box 5. An acid pickling tank 7 is also provided below the gantry frame 1. A rinsing structure is installed on the right side of the acid pickling tank 7. The up-and-down adjustment device is used to adjust and remove the conveying structure, the hollow rust removal box 5, and the hook 6. The conveying structure is used to move the hollow rust removal box 5 and the hook 6 from the acid pickling tank 7 to the rinsing structure for rinsing.

[0030] The vertical adjustment device achieves vertical movement through mechanical transmission, providing power support for placing the hollow rust removal box 5 containing the spring into or removing it from the pickling tank 7. The conveying structure utilizes horizontal transmission to transfer the hollow rust removal box 5 between the pickling tank 7 and the rinsing structure, thus forming a complete rust removal process. Through this design, the device can automate the key steps in the spring rust removal process and reduce manual operation.

[0031] The up-down adjustment device includes a vertical lead screw 31 and a linear optical axis 33. The input end of the vertical lead screw 31 is equipped with a drive motor 32. Both the vertical lead screw 31 and the linear optical axis 33 are equipped with vertical sliding blocks 34, and a mounting rod 35 is provided between the two vertical sliding blocks 34.

[0032] After the drive motor 32 is powered on, the output shaft drives the vertical lead screw 31 to rotate. According to the lead screw and nut transmission principle, the vertical sliding block 34 moves up and down along the axial direction of the lead screw under the rotation of the lead screw. The linear optical shaft 33 plays a guiding and stabilizing role, restricting the movement trajectory of the vertical sliding block 34 so that it can only move in the vertical direction, avoiding deviation or shaking during the rotation of the lead screw, and ensuring that the mounting rod 35 and the connected conveying structure, the hollow rust removal box 5 and the hook 6 can move up and down smoothly. Extended content: Through this precise up and down adjustment method, the position of the hollow rust removal box 5 can be flexibly adjusted according to the actual situation such as the depth of the pickling tank 7 and the height of the rinsing structure, ensuring that the spring is at a suitable height during pickling and rinsing, improving the rust removal effect and the safety of operation.

[0033] The conveying structure includes a mounting base 41, a second mounting groove 42 is provided at the bottom of the mounting base 41, a transverse lead screw 421 is installed inside the second mounting groove 42, a transverse slider 43 is provided at the connection of the transverse lead screw 421, a connecting threaded rod 44 is installed inside the transverse slider 43, and a rotary motor 45 is provided at the input end of the transverse lead screw 421.

[0034] After the rotating motor 45 is started, it drives the transverse lead screw 421 to rotate. The transverse slider 43 has an internal thread that matches the transverse lead screw 421. When the lead screw rotates, the transverse slider 43 moves horizontally along the direction of the transverse lead screw 421 under the action of the thread transmission. The connecting threaded rod 44 is fixed on the transverse slider 43. As the transverse slider 43 moves, the connecting threaded rod 44 drives the hook 6 and the hollow rust removal box 5 to move together in the horizontal direction, thereby moving the hollow rust removal box 5 from the pickling tank 7 to the rinsing structure.

[0035] This conveying structure can flexibly set the length and travel of the transverse lead screw 421 according to the overall layout of the rust removal device to adapt to different work site requirements. At the same time, by precisely controlling the speed and number of rotations of the rotating motor 45, the moving distance of the hollow rust removal box 5 can be precisely controlled, so that the spring can accurately enter the rinsing structure for cleaning.

[0036] The rinsing structure includes a spray tank 81, with several spray pipes 82 installed on the front and back side walls inside the spray tank 81. Each spray pipe 82 has several spray nozzles 83. A connecting pipe 84 is provided on the back side wall of the spray tank 81. A cleaning liquid storage tank 85 is provided on the back side of the spray tank 81. A pump body 86 is installed at the connection point of the connecting pipe 84 and inside the cleaning liquid storage tank 85. A discharge pipe 87 is provided at the bottom of the spray tank 81.

[0037] After the pump body 86 is started, it generates suction, which draws the cleaning liquid in the cleaning liquid storage tank 85 into the connecting pipe 84, and under pressure, it delivers the cleaning liquid to each spray pipe 82. The cleaning liquid is then sprayed out from the spray nozzle 83 on the spray pipe 82 at a certain pressure and angle, and is evenly sprayed onto the surface of the spring located in the hook part 6 to rinse the spring. The wastewater after rinsing collects at the bottom of the spray tank 81 due to gravity and is discharged to the designated location through the discharge pipe 87.

[0038] The layout design of multiple spray pipes 82 and spray nozzles 83 can rinse the spring from different angles and directions, ensuring that all parts of the spring are covered by the cleaning fluid. In particular, the gaps and corners of some complex-shaped springs can also be effectively cleaned. At the same time, the cleaning fluid with different components can be changed according to the material of the spring and the cleaning needs, thereby improving the targeting and effectiveness of the cleaning.

[0039] The mounting base 41 is fixedly connected to the mounting rod 35. The drive motor 32 drives the vertical lead screw 31 to rotate, thereby causing the vertical sliding block 34 and the mounting rod 35 to move up and down. The vertical lead screw 31 and the linear optical shaft 33 are respectively installed inside the two first mounting slots 2. The working principle is as follows: the power of the drive motor 32 is transmitted to the vertical lead screw 31 through the coupling and other transmission components, so that the vertical lead screw 31 rotates in a predetermined direction and speed. Under the drive of the lead screw, the vertical sliding block 34 slides up and down along the linear optical shaft 33 in the first mounting slot 2. Since the mounting base 41 is fixedly connected to the mounting rod 35, the mounting base 41 will move up and down synchronously with the mounting rod 35, thereby driving the entire conveying structure and the hollow rust removal box 5 and hook 6 connected to it to move up and down.

[0040] By precisely controlling the drive motor 32, the speed and position of the vertical displacement of the hollow rust removal box 5 can be precisely adjusted. When the hollow rust removal box 5 is placed into the pickling tank 7, it can be quickly lowered to near the surface of the acid solution and then slowly lowered to avoid acid splashing. When the hollow rust removal box 5 is taken out, the speed can also be adjusted according to the actual situation to ensure safe and stable operation.

[0041] The hollow rust removal box 5 is hung on the connecting threaded rod 44 by the hook 6 and fixed by the nut. The rotating motor 45 drives the horizontal screw 421 to rotate, which in turn drives the horizontal slider 43 to move, so that the hook 6 can be moved into the spray tank 81.

[0042] First, hang the hollow rust removal box 5 on the connecting threaded rod 44 via the hook 6, and then tighten the nut to fix the hook 6 to the connecting threaded rod 44, preventing the hollow rust removal box 5 from falling off during movement; when the rotating motor 45 is working, the transverse screw 421 rotates accordingly, and the transverse slider 43 moves horizontally under the transmission of the screw. Since the hook 6 is connected to the transverse slider 43, the hook 6 will move together with the transverse slider 43, thereby moving the hollow rust removal box 5 from the pickling tank 7 to the spray tank 81.

[0043] This connection method is convenient and quick, making it easy to install and disassemble the hollow rust removal box 5. When it is necessary to clean, maintain or replace the hollow rust removal box 5, simply unscrew the nut to remove the hollow rust removal box 5. At the same time, by controlling the rotating motor 45, the hollow rust removal box 5 can be kept stable during movement, avoiding the spring from falling off or being damaged due to shaking.

[0044] The pump body 86 is used to transport the cleaning liquid inside the cleaning liquid storage tank 85 through the connecting pipe 84 to several spray nozzles 83, and spray it onto the spring surface located in the hook member 6 through several spray pipes 82. The discharge pipe 87 is used to discharge the wastewater inside the spray tank 81 to a designated location.

[0045] The impeller inside the pump body 86 rotates at high speed under the drive of the motor, generating centrifugal force, which draws the cleaning liquid in the cleaning liquid storage tank 85 into the pump body 86, and pressurizes and delivers the cleaning liquid to the spray pipe 82 through the connecting pipe 84. The cleaning liquid is sprayed out from the spray nozzle 83 under pressure. The wastewater generated during the rinsing process collects at the bottom of the spray tank 81 under the action of gravity, and is discharged to a special wastewater treatment area through the pipeline system connected by the discharge pipe 87.

[0046] Valves and flow meters can be installed on the discharge pipe 87. Valves control the discharge speed and flow rate of wastewater to ensure the stability of wastewater discharge. Flow meters can monitor the discharge volume of wastewater in real time, facilitating the management and control of the wastewater treatment process. At the same time, the power and flow rate of the pump body 86 can be reasonably selected. The spray pressure and flow rate of the cleaning fluid can be adjusted according to the number of springs and cleaning requirements to ensure the cleaning effect while avoiding waste of cleaning fluid.

[0047] By setting up an up-and-down adjustment device (with vertical lead screw 31, linear optical shaft 33, drive motor 32, etc.) and a conveying structure (with horizontal lead screw 421, rotary motor 45, etc.), the up-and-down movement of the hollow rust removal box 5 and the spring, as well as the horizontal movement from the pickling tank 7 to the rinsing structure, can be automatically realized. Frequent manual operation is not required, which greatly improves the automation level of the rust removal process and increases work efficiency.

[0048] The up-down adjustment device uses a screw and nut drive and a linear optical shaft 33 guide to convert the rotational motion of the drive motor 32 into the vertical displacement of the vertical sliding block 34 and the mounting rod 35; the conveying structure uses a transverse screw 421 drive to convert the power of the rotating motor 45 into the horizontal movement of the transverse slider 43 and the hook 6. The two work together to form a complete automated conveying system, which enables the pickling and rinsing processes in the spring rust removal process to be automatically connected without the need for manual handling of the hollow rust removal box 5.

[0049] This automated design not only improves work efficiency but also reduces equipment damage and product quality issues caused by human error. Furthermore, by setting up sensors and control systems, the entire rust removal process can be intelligently controlled. Based on parameters such as the type and number of springs, the speed and position of the up-and-down adjustment and conveying can be automatically adjusted, further improving work efficiency and rust removal quality.

[0050] It reduces the direct manual involvement in loading and unloading materials and the operation during pickling and cleaning process transitions, thereby reducing the chances of operators coming into contact with harmful substances such as acids, effectively ensuring the safety of operators and reducing occupational health risks.

[0051] Because the upper and lower adjustment device and the conveying structure are automated, the operator only needs to put the spring into the hollow rust removal box 5 in the initial stage and perform simple equipment start-up and parameter settings. The subsequent pickling, moving and rinsing processes are all completed automatically by the equipment, which avoids the operator staying near the pickling tank 7 and the rinsing structure for a long time and reduces direct contact with harmful substances such as acid.

[0052] In addition, safety protection facilities such as protective covers and ventilation systems can be installed around the equipment to further reduce the harm of hazardous substances to operators. At the same time, automated operation reduces the labor intensity of operators and improves the comfort and safety of the work.

[0053] The arrangement of multiple spray pipes 82 and spray nozzles 83 in the spray tank 81 of the rinsing structure enables the cleaning fluid to be sprayed evenly on the surface of the spring, achieving a more comprehensive cleaning, ensuring the rinsing effect, and reducing acid residue.

[0054] Multiple spray pipes 82 and spray nozzles 83 are installed in the spray tank 81 in a certain layout. After the pump body 86 pressurizes and delivers the cleaning liquid to the spray pipes 82, the cleaning liquid is sprayed out from the spray nozzles 83 in different directions and angles to form an all-round rinsing coverage, ensuring that all surfaces of the spring can be fully rinsed by the cleaning liquid, thereby effectively removing residual acid and impurities from the surface of the spring.

[0055] The position, angle, and number of spray pipes 82 and spray nozzles 83 can be optimized according to the shape and size of the spring, so that the cleaning fluid can better adapt to the cleaning needs of different types of springs. At the same time, the spray pipes 82 and spray nozzles 83 should be cleaned and maintained regularly to prevent blockage, ensure the normal spraying of the cleaning fluid, and guarantee the stability of the rinsing effect.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
