Description

Technical Field

[0001] This application relates to the field of metal wire processing technology, and in particular to a spring steel wire straightening device. Background Technology

[0002] Spring steel wire, a fundamental and crucial material in the machinery manufacturing industry, is widely used in core components such as springs and fasteners. Its straightness is a key indicator determining the performance stability of the final product. Currently, the industry commonly employs multi-roller straightening technology, which uses multiple sets of staggered straightening rollers to repeatedly bend the steel wire to achieve straightening. The increasing demand for and demand for higher quality spring steel wire from the automotive industry, high-end equipment manufacturing, and other sectors have directly driven the development of straightening equipment.

[0003] However, when existing straightening equipment operates continuously for a long time, metal debris or oxide scale may adhere to the roller surface, causing scratches and pits on the spring steel during the straightening process. This directly affects the subsequent use of the spring steel. At the same time, the heat generated during the straightening process accumulates on the rollers, which can lead to a decrease in roller hardness and surface oxidation, threatening the operational stability of the straightening equipment. Utility Model Content

[0004] In order to achieve cleaning, lubrication and heat dissipation during the straightening process, this application provides a spring steel wire straightening device.

[0005] This application provides a spring steel wire straightening device. The technical solution adopted is as follows: A spring steel wire straightening device includes a chassis with several straightening back plates mounted on the chassis. Several straightening rollers are rotatably connected to the straightening back plates and are arranged in two staggered rows. A cleaning assembly is also provided on the straightening back plates for cleaning debris and scale from the straightening rollers. A slag collection assembly is fixedly provided on the chassis for adsorbing debris and scale from the straightening rollers and accelerating gas flow near the straightening rollers.

[0006] By adopting the above technical solution, when the straightening equipment is in operation, the rotating straightening rollers, together with the cleaning components, clean the debris and oxide scale adhering to the straightening rollers. The debris, oxide scale and other impurities that are cleaned off are directly sucked into the slag collection component to avoid secondary pollution. At the same time, the slag collection component will suck in the gas near the straightening rollers, accelerate the flow of the surrounding air and improve the heat dissipation efficiency of the straightening rollers.

[0007] Optionally, the cleaning assembly includes two unidirectional brush heads, which are disposed on the straightening back plate. One unidirectional brush head is disposed near the first straightening roller at the spring steel wire input end, and the other unidirectional brush head is disposed near the first straightening roller at the spring steel wire output end. A three-directional brush head is disposed between every two adjacent straightening rollers that are close to the slag collection assembly. The three-directional brush is used to clean the two adjacent straightening rollers and the straightening roller directly opposite the three-directional brush head.

[0008] By adopting the above technical solution, relying on the self-rotation of the straightening rollers, the unidirectional and tridirectional brush heads accurately clean each straightening roller, improving the cleaning effect and preventing impurities on the straightening rollers from scratching the steel wire.

[0009] Optionally, two sliding plates are slidably connected to the straightening back plate. One of the sliding plates is located at the first straightening roller at the input end of the spring steel wire, and the other sliding plate is located at the first straightening roller at the output end of the spring steel wire. The unidirectional brush head is fixedly mounted on the sliding plate, and the unidirectional brush head and the sliding plate correspond one-to-one. An adjusting member is provided on the sliding plate, and the adjusting member is used to adjust the position of the sliding plate.

[0010] By adopting the above technical solution, the unidirectional brush head can adjust the position of the sliding plate according to the needs of the straightening roller, so as to meet the cleaning or replacement needs of the straightening roller.

[0011] Optionally, the adjusting component includes ear plates located on both sides of the sliding plate. The sliding plate is fixedly mounted on the straightening back plate by bolts passing through the ear plates. The straightening back plate has two sets of threaded holes, one set of which is located close to the straightening roller and the other set of which is located away from the straightening roller. When the straightening equipment is working, the sliding plate is fixedly mounted close to the straightening roller, and the cleaning component is in contact with the straightening roller. When the straightening equipment stops working, the sliding plate is fixedly mounted away from the straightening roller, and the cleaning component is away from the straightening roller.

[0012] By adopting the above technical solution, when the straightening equipment is in operation, the sliding plate drives the one-way brush head to approach the straightening roller to clean impurities. When the straightening equipment stops working, the sliding plate drives the one-way brush away from the straightening roller to stop cleaning or replace the straightening roller.

[0013] Optionally, a lubrication assembly is slidably connected to the sliding plate. The lubrication assembly can be used to add lubricating oil to the straightening roller. When the straightening equipment is performing straightening work, the sliding plate moves downward and the cleaning assembly and the lubrication assembly operate normally. When the straightening equipment stops straightening work, the sliding plate moves upward and the cleaning assembly and the lubrication assembly can stop operating.

[0014] By adopting the above technical solution, the lubrication component adds lubricating oil to the straightening rollers. The contact between the straightening rollers and the steel wire ensures that the lubricating oil is evenly applied to the steel wire and the grooves of the straightening rollers, reducing the wear of the steel wire during the straightening process. When the straightening equipment is operating, the cleaning component cleans impurities from the straightening rollers, while the lubrication component adds lubricating oil to the straightening rollers. This prevents excessive lubricating oil from being absorbed during cleaning, which could affect the wear of the straightening rollers on the steel wire. This achieves a coordinated operation of cleaning and lubrication. When the straightening equipment stops working, the cleaning component and the lubrication component stop operating simultaneously. Only two sets of lubrication components are set up to avoid over-lubrication, which could affect the straightening effect. Furthermore, the lubrication component works in conjunction with the cleaning component. The cleaning component can remove excess lubricating oil, preventing slippage between the steel wire and the straightening roller due to excessive lubricating oil. The cleaning component is detachable for timely cleaning, preventing excessive oil absorption that could affect the cleaning effect.

[0015] Optionally, the lubrication assembly includes an oil can, which is fixedly mounted on the sliding plate. A sphere is disposed inside the oil can, the diameter of which is larger than the diameter of the oil can's opening. A lid is screwed onto the oil can's opening. A spring is fixedly mounted on the side of the lid facing the oil can, and the other end of the spring is fixedly mounted on the sphere. The spring is always in a stretched state. A support rod is fitted inside the spring, one end of which is fixedly mounted on the sphere. An oil outlet hole is provided on the lid, and the other end of the support rod passes through the oil outlet hole. A lubricating roller is rotatably connected to the straightening back plate. The lubricating roller contacts the groove of the straightening roller. When the straightening equipment is performing straightening work, when the sliding plate slides to the lubricating roller and seals the oil outlet, the ball disengages from the oil can opening. When the straightening equipment stops straightening work, the sliding plate slides to the support rod and separates from the lubricating roller, and the ball seals the oil can opening.

[0016] By adopting the above technical solution, when the straightening equipment is working, the sliding plate moves the oil can closer to the straightening roller until the lubrication roller seals the oil outlet. One end of the support rod abuts against the lubrication roller, and the other end of the support rod pushes the ball open. The lubricating oil seeps out from the oil outlet and adheres to the lubrication roller as it rotates. The lubrication roller then rolls in the groove of the straightening roller to complete the coating. When the straightening equipment stops working, the sliding plate moves the oil can away from the straightening roller, the support rod separates from the lubrication roller, and the ball resets under the tension of the spring to re-seal the oil can opening, preventing oil leakage.

[0017] Optionally, the slag collection assembly includes a vacuum cleaner, several first conveying pipes, two second conveying pipes, and at least one third conveying pipe. The vacuum cleaner is located on the chassis. One end of each of the first conveying pipes is connected to the vacuum cleaner, and the other end of each first conveying pipe is provided with an isolation net. The air inlet of each of the second conveying pipes is fixed to the straightening back plate near the one-way brush head, and each second conveying pipe corresponds to one of the one-way brush heads. The air inlet of each of the third conveying pipes is fixed to the straightening back plate near the three-way brush head, and each third conveying pipe corresponds to one of the three-way brush heads. The sidewall of the other end of each of the second and third conveying pipes is connected to the end of each of the first and third conveying pipes near the isolation net.

[0018] By adopting the above technical solution, the debris and oxide scale swept by the cleaning component are promptly adsorbed by the slag collection component, preventing impurities from falling back and causing secondary pollution. The isolation net effectively isolates impurities from entering the vacuum cleaner, preventing impurities from entering its interior and causing malfunctions. At the same time, the slag collection component will draw in the gas near the straightening roller, accelerate the surrounding airflow, and improve the heat dissipation efficiency of the straightening roller.

[0019] Optionally, both the second and third conveying pipes have disassembly ports on their sidewalls near the isolation net. A slag collection box is installed in the disassembly port. The sidewall of the slag collection box is connected to the first conveying pipe. The end of the slag collection box near the second conveying pipe is connected to the second conveying pipe. The end of the slag collection box near the third conveying pipe is connected to the third conveying pipe.

[0020] By adopting the above technical solution, impurities in the slag collection box can be cleaned regularly. At the same time, after the impurities enter the slag clamping box, they fall directly to the bottom of the slag collection box, avoiding the accumulation of impurities in the slag collection box that covers the isolation net and causes the slag collection component to fail.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When the straightening equipment is in operation, the rotating straightening rollers, together with the cleaning components, clean the debris and scale adhering to the straightening rollers. The debris, scale and other impurities that are cleaned off are directly sucked into the slag collection components to avoid secondary pollution. At the same time, the slag collection components will suck in the gas near the straightening rollers, accelerate the flow of the surrounding air and improve the heat dissipation efficiency of the straightening rollers.

[0022] 2. The lubrication component adds lubricating oil to the straightening rollers. The contact between the straightening rollers and the steel wire ensures the lubricating oil is evenly distributed between the wire and the grooves of the straightening rollers, reducing wear on the steel wire during the straightening process. When the straightening equipment is operating, the cleaning component cleans impurities from the straightening rollers, while the lubrication component adds lubricating oil. This prevents excessive oil absorption during cleaning, which could affect the wear on the steel wire caused by the straightening rollers, achieving a coordinated cleaning and lubrication process. When the straightening equipment stops working, the cleaning component and the lubrication component stop operating simultaneously. Only two sets of lubrication components are used to avoid over-lubrication, which could affect the straightening effect. The lubrication and cleaning components work together; the cleaning component removes excess lubricating oil, preventing slippage between the steel wire and the straightening rollers. The cleaning component is removable for timely cleaning, preventing excessive oil absorption that could affect the cleaning effect.

[0023] 3. When the straightening equipment is working, the sliding plate moves the oil can closer to the straightening roller until the lubrication roller seals the oil outlet. One end of the support rod abuts against the lubrication roller, and the other end of the support rod pushes the ball open. The lubricating oil seeps out from the oil outlet and adheres to the lubrication roller as it rotates. The lubrication roller then rolls in the groove of the straightening roller to complete the coating. When the straightening equipment stops working, the sliding plate moves the oil can away from the straightening roller. The support rod separates from the lubrication roller, and the ball resets under the tension of the spring to reseal the oil can opening, preventing oil leakage.

[0024] 4. The debris and scale swept by the cleaning component are promptly absorbed by the slag collection component, preventing impurities from falling back and causing secondary pollution. The isolation net effectively prevents impurities from entering the vacuum cleaner, preventing them from entering and causing malfunctions. At the same time, the slag collection component draws in air near the straightening rollers, accelerating the surrounding airflow and improving the heat dissipation efficiency of the straightening rollers. Impurities in the slag collection box can be cleaned periodically, and after entering the slag clamping box, impurities fall directly to the bottom of the slag collection box, preventing impurities from accumulating inside the slag collection box, covering the isolation net, and causing the slag collection component to malfunction.
