Description

Technical Field

[0001] This invention relates to the field of thread rolling machine technology, and more specifically to a fully automatic multi-station thread rolling machine with dynamic load balancing. Background Technology

[0002] Fully automatic multi-station thread rolling machines are key equipment in the modern thread processing field, widely used for efficient and high-precision thread rolling of metal materials such as standard parts, automotive parts, and building steel bars. Through simultaneous operation of multiple stations, they significantly improve production efficiency and thread surface quality, making them suitable for large-scale continuous production.

[0003] However, during thread rolling, a large amount of fine metal debris is generated between the workpiece and the rolling wheel due to high-speed rolling. This debris mainly originates from plastic deformation and flash breakage on the workpiece surface. If it cannot be effectively separated and recovered from the thread rolling oil in a timely manner, it will re-enter the machining area along with the oil, not only accelerating the wear of the rolling wheel and the working contact surface but also affecting the surface finish and dimensional consistency of the thread, and even causing product scrap. Although some existing equipment is equipped with simple filtering devices, problems such as incomplete debris separation, inconvenient collection, and the need for machine shutdown for cleaning are still common, making it difficult to adapt to the pace of continuous multi-station production.

[0004] Furthermore, the intense deformation and friction during thread rolling generate a large amount of heat, causing the thread rolling oil temperature to rise rapidly. Excessively high oil temperature leads to a decrease in viscosity and a decline in lubrication performance, further affecting processing quality. Currently, many existing equipment still rely on natural cooling to cool the thread rolling oil. This method is inefficient, with heat dissipation lagging far behind the rate of heat generation, easily causing the oil temperature to accumulate and rise continuously. This not only forces production to be interrupted to wait for cooling but also makes it impossible to control the oil temperature.

[0005] In summary, it is necessary to develop a fully automatic multi-station thread rolling machine with dynamic load balancing to solve the above problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a fully automatic multi-station thread rolling machine with dynamic load balancing, comprising: a machine housing, a limit groove, thread rolling wheels, an oil inlet pipe, and an oil outlet. The machine housing integrates a cooling component, and a filter mechanism is disposed below the thread rolling wheels. This filter mechanism further comprises: A magnetic vortex separation component is installed on the inner wall of the chassis and includes a servo motor. The filter mechanism is used to separate and collect metal debris generated during the gear rolling process. The magnetic vortex separation component is used to generate centrifugal force during rotation to achieve preliminary separation of oil debris and to magnetically attract fine debris.

[0007] A scraping component is installed on the outer surface of the magnetic spin separation component, and the scraping component is provided with a scraping plate; the scraping component is used to automatically scrape off metal debris adsorbed on the surface of the magnetic spin separation component.

[0008] A chip collection component is attached to the outer surface of the magnetic separation component. The chip collection component includes a magnetic collecting plate. The magnetic collecting plate is made of magnetic material to further enhance the adsorption and collection of chips. It can be made of nickel-plated neodymium iron boron magnetic material, matching the material of the adsorption plate, ensuring stable adsorption of metal chips at high temperatures. The nickel plating layer further enhances its high-temperature resistance. The chip collection component is used to collect the scraped-off chips for easy centralized recycling.

[0009] Furthermore, the cooling component includes: An oil outlet pipe is provided, with a heat pipe heat exchanger fixedly connected to its bottom end. A return oil pipe is installed at the end of the heat pipe heat exchanger furthest from the oil outlet pipe, and a temperature sensor is mounted on the outer surface of the return oil pipe. The cooling components rapidly cool the circulating lubricating thread rolling oil to maintain system thermal balance. The heat pipe heat exchanger utilizes its high thermal conductivity to achieve efficient heat exchange between the oil and the cooling medium. The return oil pipe guides the cooled oil back to the lubrication system. The oil outlet pipe, heat pipe heat exchanger, and return oil pipe are compactly integrated. The heat pipe heat exchanger contains two water-cooled pipes for water exchange and flow with an external cooling tower.

[0010] Furthermore, the outer surfaces of the oil outlet pipe, the heat pipe heat exchanger, and the oil return pipe are all mounted on the inner surface of the casing. The end of the oil return pipe furthest from the heat pipe heat exchanger is fixedly connected to one end of the oil inlet pipe. The temperature sensor is installed inside the casing. The temperature sensor is electrically connected to the equipment's control system.

[0011] Furthermore, the output end of the servo motor is fixedly connected to a rotating shaft, and an oil reservoir is rotatably connected to the lower part of the outer surface of the rotating shaft. The outer surface of the rotating shaft has grooves, and a separating plate is fixedly connected to the upper part of the outer surface of the rotating shaft. The grooves facilitate the engagement of the scraping components to provide lifting and lowering motion; the separating plate is designed with a high center and low edges to generate centrifugal force during rotation, promoting the separation of oil and debris and providing kinetic energy to the debris.

[0012] Furthermore, a baffle plate is arranged around the outer side of the centrifugal plate, and an adsorption plate is embedded in the inner surface of the baffle plate. A positioning groove is provided on the lower surface of the baffle plate. The centrifugal plate is made of 316 stainless steel, which has good high-temperature resistance and corrosion resistance, can adapt to the complex environment of thread rolling oil, and has high mechanical strength to withstand centrifugal force. The adsorption plate is made of magnetic material to further adsorb residual fine metal debris after centrifugal separation. The adsorption plate uses nickel-plated neodymium iron boron magnetic material, which has high magnetic energy product and high energy density, effectively adsorbing metal debris. The nickel plating treatment improves its high-temperature resistance and oxidation resistance, allowing it to maintain good magnetism even at high temperatures. The positioning groove is used to position the chip collection component.

[0013] Furthermore, the servo motor is mounted on the inner surface of the chassis, the oil storage tank is mounted on the inner surface of the chassis, the bottom of the oil storage tank is connected to the top of the oil outlet pipe, and the outer surface of the baffle plate is fixedly connected to the inner surface of the chassis. The oil storage tank is mounted on the inner surface of the chassis to form an integral structural support; the baffle plate is made of 304 stainless steel, which is low in cost, has certain high temperature resistance and corrosion resistance, meets the requirements for the use of baffle plates in thread rolling machines, and is easy to process.

[0014] Furthermore, a fixing rod is installed on the lower surface of the cutting plate, and a lifting block is installed at the end of the fixing rod away from the cutting plate. The function of the fixing rod is to connect and support the cutting plate, and its cooperation with the wire groove can convert the rotational motion of the shaft into the linear motion of the cutting plate. The cutting plate is made of polyurethane material, which has good wear resistance and is softer than the adsorption plate. It will not scratch the adsorption plate during friction, and can withstand the scraping of metal debris for a long time. It will not swell, deform or lose strength when soaked in thread rolling oil. It can withstand high oil temperature and has a certain rigidity, which can scrape off the debris.

[0015] Furthermore, the side of the cutting plate away from the rotating shaft is slidably connected to the side of the baffle plate near the rotating shaft, the side of the cutting plate near the baffle plate is slidably connected to the side of the adsorption plate near the rotating shaft, and the lifting block is threadedly connected to the wire groove.

[0016] Furthermore, a pull plate is installed on the outer surface of the magnetic collecting plate on the side away from the rotating shaft. The function of the pull plate is to facilitate the operator to disassemble and clean up the collected debris.

[0017] Furthermore, the magnetic collecting plate is embedded in the inner surface of the positioning groove, and the outer surface of the pull plate is slidably connected to the inner surface of the limiting groove. The positioning groove can accurately position the magnetic collecting plate, and the limiting groove can guide the chip collecting component to be pulled along a predetermined trajectory, ensuring smooth operation and easy maintenance.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a magnetic gyratory separation component, combining a gyratory plate structure with a high center and low periphery, and an adsorption plate made of nickel-plated neodymium iron boron material. During rotation, centrifugal force and magnetic force are used to efficiently separate oil and metal shavings, effectively solving the problem of metal shavings being difficult to remove from thread rolling oil. This avoids the problem of increased wear on the thread rolling wheels and decreased processing quality caused by shavings circulation, providing a clean oil guarantee for multi-station continuous thread rolling. The scraping component converts the rotational motion into the linear scraping motion of the polyurethane scraping plate through wire groove transmission. This automatically removes shavings from the surface of the adsorption plate in a high-temperature oil environment, avoiding the inconvenience of manual cleaning and downtime losses. Its soft material properties protect the magnetic adsorption surface from scratches. This design effectively prevents damage while ensuring the continuous reliability of the scraping action. The chip collection component uses an inclined semi-circular magnetic plate with a pull-out structure to achieve centralized adsorption and rapid recovery of scraped chips without stopping the machine, avoiding the production interruption problem caused by the need to stop the machine for cleaning in traditional filtration systems. The cooling component relies on a built-in heat pipe heat exchanger and circulating oil circuit to cool the thread rolling oil in real time. Combined with the magnetic separation and scraping collection system, it forms a dynamic treatment system that integrates filtration, cooling, and recovery. This fundamentally avoids the problems of decreased lubrication performance and shortened life of the thread rolling wheel caused by increased oil temperature, ensuring the stable operation of the fully automatic multi-station thread rolling machine under long-term high-load conditions.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] For the first embodiment, please refer to... Figures 1-7 This invention is a fully automatic multi-station thread rolling machine with dynamic load balancing, comprising: a housing 1, a limiting groove 2, a thread rolling wheel 3, an oil pipe 4, and an oil outlet 5. The housing 1 integrates a cooling component 6, and a filter mechanism 7 is located below the thread rolling wheel 3. This filter mechanism 7 also has the following features: The magnetic vortex separation component 71 is installed on the inner wall of the housing 1 and includes a servo motor 711. The filter mechanism 7 is used to separate and collect metal debris generated during the gear rolling process. The magnetic vortex separation component 71 is used to generate centrifugal force during rotation to achieve preliminary separation of oil debris and to attract fine debris by magnetic force.

[0023] The scraping component 72 is installed on the outer surface of the magnetic separation component 71 and is provided with a scraping plate 721. The scraping component 72 is used to automatically scrape off metal debris adsorbed on the surface of the magnetic separation component 71.

[0024] The chip collecting component 73 is attached to the outer surface of the magnetic separation component and includes a magnetic collecting plate 731. The magnetic collecting plate 731 is made of magnetic material to further enhance the adsorption and collection of chips. It can be made of nickel-plated neodymium iron boron magnetic material, consistent with the material of the adsorption plate 717, ensuring stable adsorption of metal chips at high temperatures. The nickel plating layer enhances its high-temperature resistance. The chip collecting component 73 is used to collect the scraped-off chips for easy centralized recycling.

[0025] Cooling component 6 includes: An oil outlet pipe 61 is provided, with a heat pipe heat exchanger 62 fixedly connected to its bottom end. A return oil pipe 63 is installed at the end of the heat pipe heat exchanger 62 furthest from the oil outlet pipe 61, and a temperature sensor 64 is mounted on the outer surface of the return oil pipe 63. The cooling component 61 rapidly cools the circulating lubricating thread rolling oil to maintain system thermal balance. The heat pipe heat exchanger 62 utilizes its high thermal conductivity to achieve efficient heat exchange between the oil and the cooling medium. The return oil pipe 63 guides the cooled oil back to the lubrication system. The oil outlet pipe 61, heat pipe heat exchanger 62, and return oil pipe 63 are compactly integrated. The heat pipe heat exchanger 62 contains two water-cooled pipes for water exchange and flow with an external cooling tower. The probe of the temperature sensor 64 extends into the return oil pipe 63 to monitor the oil temperature after it has been cooled by the heat pipe heat exchanger 62 in real time.

[0026] The outer surfaces of the oil outlet pipe 61, the heat pipe heat exchanger 62, and the oil return pipe 63 are all mounted on the inner surface of the casing 1. The end of the oil return pipe 63 away from the heat pipe heat exchanger 62 is fixedly connected to one end of the oil passage pipe 4. The temperature sensor 64 is installed inside the casing 1. The temperature sensor 64 is electrically connected to the equipment's control system.

[0027] The output end of the servo motor 711 is fixedly connected to a rotating shaft 712. The lower part of the outer surface of the rotating shaft 712 is rotatably connected to an oil reservoir 713. The outer surface of the rotating shaft 712 is provided with a thread groove 714, and the upper part of the outer surface of the rotating shaft 712 is fixedly connected to a separating plate 715. The thread groove 714 is designed to facilitate the engagement of the scraping component 72 to provide lifting and lowering motion. The separating plate 715 is designed with a high center and low edges to generate centrifugal force during rotation, promote the separation of oil and debris, and provide kinetic energy to the debris.

[0028] A baffle plate 716 is arranged around the outer side of the centrifugal plate 715. An adsorption plate 717 is embedded in the inner surface of the baffle plate 716, and a positioning groove 718 is provided on the lower surface of the baffle plate 716. The centrifugal plate 715 is made of 316 stainless steel, which has good high temperature resistance and corrosion resistance, can adapt to the complex environment of thread rolling oil, and has high mechanical strength to withstand centrifugal force. The adsorption plate 717 is made of magnetic material and is used to further adsorb residual fine metal debris after centrifugal separation. The adsorption plate 717 is made of nickel-plated neodymium iron boron magnetic material, which has high magnetic energy and high energy density, and can effectively adsorb metal debris. Because the nickel plating treatment can improve its high temperature resistance and oxidation resistance, it can still maintain good magnetism in high temperature environment. The positioning groove 718 is used to position the chip collection component 73.

[0029] The servo motor 711 is mounted on the inner surface of the housing 1, and the oil reservoir 713 is also mounted on the inner surface of the housing 1. The bottom of the oil reservoir 713 is connected to the top of the oil outlet pipe 61, and the outer surface of the baffle plate 716 is fixedly connected to the inner surface of the housing 1. The oil reservoir 713 is mounted on the inner surface of the housing 1 to form an integral structural support. The baffle plate 716 is made of 304 stainless steel, which is low in cost and has certain high temperature resistance and corrosion resistance, meeting the requirements for the use of the baffle plate 716 in the thread rolling machine, and is easy to process.

[0030] The specific work process is as follows: First, the thread rolling machine in this device operates with multiple stations simultaneously. During operation, the rolling wheels 3 roll the metal rod at high speed, generating a large amount of frictional heat and producing fine metal debris. The thread rolling oil mixed with the high-temperature debris is collected in the oil storage tank 713 located below the rolling wheels 3 by the internal circulation system of the equipment. It should be explained that thread rolling is a plastic deformation, not cutting, so it does not produce long strips of chips like those produced by a lathe. However, it does produce very fine, flaky metal debris, mainly from the peeling off of microscopic unevenness on the workpiece surface, and the "flash" or "burr" fracture generated when the workpiece material is squeezed. Although these debris are small, if they are mixed with the thread rolling oil and recycled, they will greatly aggravate the wear of the rolling wheels and the equipment, affecting the surface quality of the thread. Therefore, they must be filtered and removed. The role of the thread rolling oil is to form a strong chemical protective film under high pressure, reducing the wear of the rolling wheels and preventing "burning" and premature wear on the tooth surface.

[0031] The servo motor 711 starts, driving the rotating shaft 712 and the swivel plate 715 fixed on it to rotate. Because the swivel plate 715 is designed with a special curved surface shape that is high in the middle and low around the edges, it can efficiently throw the oil debris mixture in the oil storage tank 713 to the surrounding areas when rotating. The thrown oil debris mixture hits the outer surface of the adsorption plate 717 embedded in the inner wall of the surrounding baffle 716. The adsorption plate 717 is made of nickel-plated neodymium iron boron magnetic material. With its high magnetic energy and excellent high temperature resistance, it can stably and efficiently adsorb the magnetic metal debris flowing through it under complex working conditions. At the same time, the thread rolling oil flows back down along the surface of the adsorption plate 717 to the bottom oil storage tank 713, thereby realizing the separation of the thread rolling oil and the metal debris. During this process, centrifugal force provides sufficient kinetic energy to the fine metal fragments, allowing them to be thrown onto the surface of the adsorption plate 717, effectively preventing the particles from falling back directly with the oil because they are too small to reach the adsorption surface.

[0032] For the second embodiment, please refer to... Figures 1-9The present invention provides a technical solution: Based on Embodiment 1, a fixing rod 722 is installed on the lower surface of the cutting plate 721, and a lifting block 723 is installed at the end of the fixing rod 722 away from the cutting plate 721. The function of the fixing rod 722 is to connect and support the cutting plate 721, and its cooperation with the wire groove 714 can be used to convert the rotational motion of the rotating shaft 712 into the linear motion of the cutting plate 721. The cutting plate 721 is made of polyurethane material, which has good wear resistance and is softer than the adsorption plate 717. It will not scratch the adsorption plate 717 during friction, and can withstand the scraping of metal shavings for a long time. It will not swell, deform or lose strength when soaked in thread rolling oil. It can withstand high oil temperature and has a certain rigidity, which can scrape off the shavings.

[0033] The side of the cutting plate 721 away from the rotating shaft 712 is slidably connected to the side of the baffle plate 716 near the rotating shaft 712. The side of the cutting plate 721 near the baffle plate 716 is slidably connected to the side of the adsorption plate 717 near the rotating shaft 712. The lifting block 723 is threadedly connected to the wire groove 714.

[0034] A pull plate 732 is installed on the outer surface of the magnetic collecting plate 731 on the side away from the rotating shaft 712. The function of the pull plate 732 is to facilitate the operator to disassemble and clean up the collected debris.

[0035] The magnetic collecting plate 731 is embedded in the inner surface of the positioning groove 718, and the outer surface of the pull plate 732 is slidably connected to the inner surface of the limiting groove 2. The outer surface of the magnetic collecting plate 731 is also slidably connected to the inner surface of the limiting groove 2. The positioning groove 718 can accurately position the magnetic collecting plate 731, and the limiting groove 2 can guide the chip collecting component 73 to be pulled along a predetermined trajectory, ensuring smooth operation and easy maintenance.

[0036] The specific work process is as follows: As the servo motor 711 continues to operate, the thread groove 714 on the outer surface of the rotating shaft 712 engages with the lifting block 723 in a threaded transmission, converting the rotational motion of the rotating shaft 712 into the linear lifting motion of the scraping component 72. The lifting block 723 moves downward along the thread groove 714, causing the scraping plate 721, fixed to one end of the fixed rod 722, to move downward against the surface of the adsorption plate 717, thereby continuously and automatically scraping away the metal debris attached to the plate. The scraped debris falls to the magnetic collecting plate 731 below under the action of gravity. The magnetic collecting plate 731 is arranged at a certain angle below the adsorption plate 717 and also uses nickel-plated neodymium iron boron magnetic material, which can effectively adsorb and collect debris to prevent it from escaping, while the separated thread rolling oil falls into the oil storage tank 713 for recycling. The servo motor 711 controls the intermittent forward and reverse rotation of the rotating shaft 712.

[0037] Combination Figures 5 to 7 The image shows the state changes of the cutting plate 721 at different heights: Figure 5 In this process, a suitable gap is maintained between the bottom of the scraping plate 721 and the upper surface of the swirl plate 715, allowing the oil and debris mixture ejected by the swirl plate 715 to smoothly reach the surface of the adsorption plate 717 without the scraping plate 721 interfering with the process. At this time, the adsorbed debris is located below the scraping plate 721, providing conditions for subsequent scraping. During scraping, the scraping force is significantly greater than the magnetic adsorption force of the adsorption plate 717 on the fine debris.

[0038] Figure 7 In this configuration, the scraping plate 721 is in a low position, and all the mixture on the surface of the separating plate 715 falls to the interface between the upper surfaces of the scraping plate 721 and the upper surfaces of the separating plate 715, no longer contacting the adsorption plate 717. In this state, a very small, controllable gap of 0.05–0.2 mm is maintained between the side edge of the separating plate 715 and the vertical surface of the scraping plate 721, avoiding wear caused by rotational contact. Although there may be a small amount of oil leakage, it is within a controllable range and far superior to damage caused by direct friction. Subsequent metal debris scraped off by the scraping plate 721 will fall onto the upper surface of the magnetic collecting plate 731 and be adsorbed.

[0039] Subsequently, the servo motor 711 reverses, driving the rotating shaft 712 to rotate in the opposite direction. Through the wire groove 714, the lifting block 723 drives the removal plate 721 to move upward. After moving upward a certain distance, a gap appears between the bottom of the removal plate 721 and the upper surface of the separation plate 715. The oil and shaving mixture accumulated on it slides back along the inclined upper surface of the removal plate 721 to the separation plate 715 and is once again thrown onto the surface of the adsorption plate 717 for adsorption.

[0040] The profile design and lifting stroke of the cutting plate 721 have been precisely calculated. For example... Figure 7 As shown, the top edge of the removal plate 721 is flush with the height of the adsorption plate 717, and the bottom edge is slightly lower than the lower boundary of the adsorption plate 717. This ensures that the oil shavings on the surface of the rotating plate 715 can be blocked during the upward movement, preventing the oil shavings from directly contacting the adsorption plate 717. Its upper surface is designed with an inclination to facilitate the sliding of the mixture.

[0041] If the removal plate 721 moves downwards excessively, part of the adsorption plate 717 will be exposed, and debris thrown out by the separation plate 715 will be directly adsorbed into this area. Subsequently, when the removal plate 721 moves upwards, it will scrape off these debris, causing them to adhere to its inclined upper surface. If the debris is small, it may be further broken down under the shearing action of scraping, forming even finer particles, which may escape through the gap between the removal plate 721 and the separation plate 715, increasing the difficulty of recycling.

[0042] This device adds a magnetic collecting plate 731 to the adsorption plate 717 to jointly achieve the adsorption and collection of metal debris. Since the multi-station thread rolling machine needs to run continuously and the thread rolling oil needs to be continuously supplied, the adsorption plate 717 can still maintain the necessary adsorption function when the magnetic collecting plate 731 is removed for cleaning, ensuring that the equipment does not stop.

[0043] When the scraping plate 721 moves downward to perform scraping, without the magnetic collecting plate 731, the debris cannot be collected. Therefore, the servo motor 711 and the chassis 1 are linked for control: when the servo motor 711 reverses and the scraping plate 721 moves upward (i.e., in non-scraping state), the encoder of the servo motor 711 provides real-time feedback of rotor position, speed, and direction signals to the servo driver. The driver's internal program continuously monitors the direction signal. When the speed or torque command changes from positive to negative, it determines that the motor is reversing and sends a "reverse state" signal through the digital output point. This signal is transmitted to the human-machine interface, triggering the reverse state indicator light on the screen to illuminate. At this time, the operator can pull the pull plate 732 to pull the magnetic collecting plate 731 out along the limiting groove 2. The magnetic collecting plate 731 is semi-circular, causing the debris to be distributed in a ring shape, which is conducive to centralized cleaning. When replacing the magnetic collecting plate 731, push it into the chassis 1 until the outer surface contacts the locking groove 718, indicating that it is installed in place. The cleaned magnetic collecting plate 731 can be reused.

[0044] Finally, the high-temperature oil in the oil storage tank 713 flows through the oil outlet pipe 61 into the heat pipe heat exchanger 62, where it undergoes efficient heat exchange with the cooling medium through its high thermal conductivity, achieving rapid cooling. The cooled oil then flows back to the oil passage pipe 4 through the oil return pipe 63, re-entering the lubrication circulation system to achieve continuous utilization of the oil.

[0045] To ensure stable system operation, a temperature sensor 64 is installed in the return oil pipe section 63 to monitor the temperature of the cooled oil in real time. The control system inside the chassis 1 has a preset temperature threshold of 40℃–50℃. This range ensures that the thread rolling oil is within its optimal viscosity and lubrication performance range, while also preventing problems such as decreased lubrication performance and accelerated wear of the thread rolling gears due to excessively high oil temperature. When the return oil temperature exceeds this threshold, the control system can directly cut off the main power supply to the thread rolling machine and stop the equipment from operating, thereby avoiding operation under abnormal oil temperature conditions, effectively protecting the thread rolling gears 3, and maintaining the dimensional consistency and surface quality of the machined threads. When the oil temperature recovers and remains below the set threshold, the equipment can automatically or manually resume operation.

[0046] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
