Description

Technical Field

[0001] This utility model relates to the field of steel shot production technology, specifically a heat treatment device for steel shot production. Background Technology

[0002] Steel shot is a spherical particle made of special materials through special heat treatment. It is mainly used in sandblasting and surface treatment processes. During the production process, steel shot needs to be heat-treated to make it more tough.

[0003] The heat treatment equipment for steel shot production mainly consists of guide rails, heating elements, and a cooling mechanism. During heat treatment, the steel shot is first placed on a rack. Then, a cylinder moves the steel shot from the rack into the coil. Once inside the coil, the power is turned on, energizing the coil and generating heat to heat the steel shot. After heating, the steel shot is moved from the coil into an annular tube by the cylinder. A pump is then activated, supplying cold water from the cooling tank to the annular tube. The cold water is sprayed onto the surface of the steel shot through nozzles in the annular tube, cooling the heated shot and completing the heat treatment process. This heat treatment significantly improves the hardness of the steel shot.

[0004] Existing heat treatment equipment for steel shot production cannot automatically feed steel shot during heat treatment, thus preventing its integration with other heat treatment equipment to form a complete automated production line, which greatly reduces work efficiency. Therefore, a heat treatment equipment for steel shot production is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a heat treatment device for steel shot production.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A heat treatment device for steel shot production according to this utility model includes a base, an L-shaped support plate fixedly connected to the base, a fixing block installed on the side wall of the L-shaped support plate, a fixing cylinder installed on the fixing block, a rotating wheel installed inside the fixing cylinder via a rotating shaft, a first motor installed on one side wall of the fixing cylinder, the output end of the first motor connected to one end of the rotating shaft, four guide ports opened on the rotating wheel, a feed pipe connected to the top of the circumferential surface of the fixing cylinder, a storage hopper connected to the feed pipe and fixedly connected to the L-shaped support plate, and a feeding pipe connected to the bottom of the circumferential surface of the fixing cylinder, the feeding pipe being positioned directly above the placement plate for feeding steel shot. When the first motor is started, the rotating wheel rotates, which in turn rotates the guide port. When the guide port aligns with the feed pipe below the storage hopper, the steel shot in the storage hopper falls into the guide port. At this time, as the rotating wheel continues to rotate, when the guide port aligns with the feeding pipe, the steel shot in the guide port falls into the positioning groove on the placement plate through the feeding pipe. This enables automatic feeding of steel shot, allowing for rapid and continuous delivery of steel shot to designated positions, facilitating subsequent continuous heat treatment of the steel shot. This automatic feeding system can be integrated with other heat treatment equipment to form a complete automated production line, greatly improving work efficiency while reducing direct contact between operators and high-temperature heat treatment devices, thus reducing the safety risks of burns and scalds.

[0007] Preferably, a rotating column is rotatably mounted on the base, a rotating disk is fixedly connected to the top of the rotating column, a driven gear is fitted on the rotating column, a second motor is mounted on the base, and a driving gear is installed at the output end of the second motor. The driving gear and the driven gear mesh with each other. When heat treating the steel shot, the second motor is started, causing the driving gear to rotate, which forces the driven gear to drive the rotating column to rotate, thereby causing the rotating disk to drive the steel shot to rotate as well. This allows the steel shot to be intermittently or continuously transported into the heat treatment mechanism, facilitating subsequent intermittent or continuous heat treatment of the steel shot.

[0008] Preferably, multiple pneumatic cylinders are installed on the top side of the rotating disk. Each pneumatic cylinder is equipped with a pneumatic rod at its working end. The top ends of two pneumatic rods are fixedly connected to a placement plate. Each placement plate has a positioning groove and three fixing rods are fixed on each placement plate. The top ends of the three fixing rods are fixedly connected to a protective ring. When using the device, the pneumatic cylinders operate to move the pneumatic rods to move the placement plate and steel shot up or down, thereby raising or lowering the steel shot to the required position as needed. By setting the protective rings, the steel shot can be prevented from falling off the placement plate.

[0009] Preferably, a fixing frame is mounted on the base, a coil is mounted on the inner wall of the fixing frame, and a power supply is provided on the outer wall of the fixing frame. The power supply is electrically connected to the coil. Two mounting rods are fixedly connected to one side wall of the fixing frame, and an annular tube is fixedly connected to the two mounting rods. The annular tube has multiple spray holes and is located below the coil. A cold water tank is mounted on the top side of the fixing frame, and a water pump is mounted on the cold water tank. The output port of the water pump is connected to a water pipe channel, and the other end of the water pipe channel is connected to the annular tube. When the steel shot is heat-treated, when the steel shot rotates to the heat treatment mechanism, a pneumatic cylinder is used to move the placement plate and the steel shot upward. When the steel shot moves into the coil, The power is turned on, energizing the coil to generate heat, which heats the steel shot. After heat treatment, the steel shot is moved from the coil into the annular tube by a pneumatic cylinder. The water pump is started, supplying cold water from the cooling tank to the annular tube. The cold water is sprayed onto the surface of the steel shot through nozzles in the annular tube, cooling the heated steel shot and completing the heat treatment process. This significantly improves the hardness of the steel shot. With the cooperation of the automatic feeding mechanism and the rotating mechanism, the entire heat treatment process can be carried out intermittently or continuously. This means that while one steel shot is undergoing heat treatment, the next steel shot is ready to be fed into the designated position, thus achieving efficient, continuous, and high-quality production.

[0010] The advantages of this utility model are:

[0011] 1. In this invention, when feeding steel shot, the first motor is started, causing the rotating wheel to rotate, which in turn causes the guide port to rotate. When the guide port rotates to coincide with the feed pipe below the storage hopper, the steel shot in the storage hopper will fall into the guide port. At this time, as the rotating wheel continues to rotate, when the guide port rotates to coincide with the feed pipe, the steel shot in the guide port will fall into the positioning groove on the placement plate through the feed pipe, thereby realizing automatic feeding of steel shot. It can quickly and continuously feed steel shot to the designated position, which is convenient for subsequent continuous heat treatment of steel shot. This automatic feeding system can be integrated with other heat treatment equipment to form a complete automated production line, which greatly improves work efficiency and reduces the direct contact between operators and high-temperature heat treatment equipment, reducing the safety risks of burns and scalds.

[0012] 2. In the heat treatment of steel shot, when the steel shot rotates to the heat treatment mechanism, a pneumatic cylinder moves the placement plate and steel shot upwards. When the steel shot moves into the coil, the power is turned on, energizing the coil and generating heat to heat the steel shot. After heat treatment, the pneumatic cylinder moves the steel shot downwards from the coil into the annular tube. A water pump is then activated, spraying cold water onto the surface of the steel shot through nozzles in the annular tube, thus cooling the heated steel shot and completing the heat treatment. This significantly improves the hardness of the steel shot. With the cooperation of the automatic feeding mechanism and the rotating mechanism, the entire heat treatment process can be carried out intermittently and continuously. This means that while one steel shot is undergoing heat treatment, the next steel shot is ready to be placed in the designated position, thereby achieving efficient, continuous, and high-quality production.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-2 As shown, a heat treatment device for steel shot production includes a base 1, an L-shaped support plate 2 fixedly connected to the base 1, a fixing block 3 installed on the side wall of the L-shaped support plate 2, a fixing cylinder 4 installed on the fixing block 3, a rotating wheel 10 installed inside the fixing cylinder 4 via a rotating shaft 9, a first motor 8 installed on one side wall of the fixing cylinder 4, the output end of the first motor 8 connected to one end of the rotating shaft 9, four guide ports 11 opened on the rotating wheel 10, a feed pipe 6 connected to the top of the circumferential surface of the fixing cylinder 4, a storage hopper 5 connected to the feed pipe 6 and fixed to the L-shaped support plate 2, and a feeding pipe 7 connected to the bottom of the circumferential surface of the fixing cylinder 4, and the feeding pipe 7 is positioned directly above the placement plate 18; during operation, when feeding steel shot, the first motor 8 is started, causing the rotating wheel 10 to rotate, thereby causing the guide ports 11 to rotate. As the rotating wheel 10 rotates, when the guide port 11 aligns with the feed pipe 6 below the storage hopper 5, the steel shot in the storage hopper 5 will fall into the guide port 11. At this time, the guide port 11 serves to temporarily store and guide the steel shot. As the rotating wheel 10 continues to rotate, when the guide port 11 aligns with the feeding pipe 7, the steel shot in the guide port 11 will fall into the positioning groove 21 on the placement plate 18 through the feeding pipe 7, thereby realizing automatic feeding of steel shot. It can quickly and continuously feed steel shot to the designated position, which is convenient for subsequent continuous heat treatment of steel shot. This automatic feeding system can be integrated with other heat treatment equipment to form a complete automated production line, which greatly improves work efficiency and reduces direct contact between operators and high-temperature heat treatment equipment, reducing the safety risks of burns and scalds.

[0022] Please see Figure 4-5As shown, a rotating column 12 is rotatably mounted on the base 1, and a rotating disk 13 is fixedly connected to the top of the rotating column 12. A driven gear 14 is fitted on the rotating column 12. A second motor 15 is mounted on the base 1, and a driving gear 16 is installed at the output end of the second motor 15. The driving gear 16 and the driven gear 14 mesh with each other. During operation, when heat treating steel shot, after the steel shot is placed into the positioning groove 21 on the placement plate 18, the protective ring 20 prevents the steel shot from falling off the placement plate 18. The second motor 15 is started, causing the driving gear 16 to rotate, which forces the driven gear 14 to drive the rotating column 12 to rotate. This causes the rotating disk 13 to drive the steel shot to rotate as well, which can intermittently and continuously transport the steel shot into the heat treatment mechanism, facilitating subsequent intermittent and continuous heat treatment of the steel shot.

[0023] Multiple pneumatic cylinders 17 are installed on the top side of the rotating disk 13. Each pneumatic cylinder 17 is equipped with a pneumatic rod at its working end. The top ends of two pneumatic rods are fixedly connected to a placement plate 18. Each placement plate 18 has a positioning groove 21. Each placement plate 18 is fixed with three fixing rods 19. The top ends of the three fixing rods 19 are fixedly connected to a protective ring 20. When using the device, the pneumatic cylinders 17 are operated to drive the pneumatic rods to move the placement plate 18 and the steel shot up or down, thereby raising or lowering the steel shot to the required position as needed.

[0024] Please see Figure 1 and Figure 3As shown, a mounting bracket 22 is installed on the base 1. A coil 23 is installed on the inner wall of the mounting bracket 22, and a power supply 24 is installed on the outer wall of the mounting bracket 22. The power supply 24 is electrically connected to the coil 23. Two mounting rods 25 are fixedly connected to one side wall of the mounting bracket 22. An annular tube 26 is fixedly connected to the two mounting rods 25. Multiple spray holes 27 are opened on the annular tube 26, and the annular tube 26 is located below the coil 23. A cold water tank 28 is installed on the top side of the mounting bracket 22. A water pump 29 is mounted on the cold water tank 28. The output hole of the water pump 29 is connected to a water pipe channel 30, and the other end of the water pipe channel 30 is connected to the annular tube 26. During operation, when the steel shot is heat-treated, when the steel shot rotates to the heat treatment mechanism, the pneumatic cylinder 17 operates, causing the pneumatic rod to drive the placement plate 18 and the steel shot to move upward. When the steel shot moves upward to the coil... When the coil 23 is in operation, the power supply 24 is activated, which energizes the coil 23 and generates heat, thereby heating the steel shot. After the steel shot is heated, the pneumatic cylinder 17 operates again, causing the steel shot to move from the coil 23 into the annular tube 26. The water pump 29 is activated, which delivers cold water from the cold water tank 28 to the annular tube 26 through the water pipe channel 30. The cold water is sprayed onto the surface of the steel shot through the nozzle 27 in the annular tube 26, thereby cooling the heated steel shot and completing the heat treatment of the steel shot. This significantly improves the hardness of the steel shot. With the cooperation of the automatic feeding mechanism and the rotating mechanism, the entire heat treatment process can be carried out intermittently and continuously. This means that while one steel shot is undergoing heat treatment, the next steel shot is ready to be delivered to the designated position, thus achieving efficient, continuous, and high-quality production.

[0025] Working Principle: Existing steel shot production heat treatment equipment cannot automatically feed steel shot during heat treatment, thus preventing integration with other heat treatment equipment to form a complete automated production line, significantly reducing work efficiency. Therefore, to address this problem, a steel shot production heat treatment device is proposed. When feeding steel shot, the first motor 8 is started, causing the rotating wheel 10 to rotate, which in turn causes the guide port 11 to rotate. When the guide port 11 rotates to coincide with the feed pipe 6 below the storage hopper 5, the steel shot in the storage hopper 5 falls into the guide port 11. At this time, the guide port 11 temporarily... The function of storing and guiding steel shot is that, as the rotating wheel 10 continues to rotate, when the guide port 11 rotates to coincide with the feeding pipe 7, the steel shot in the guide port 11 will fall into the positioning groove 21 on the placement plate 18 through the feeding pipe 7, thereby realizing automatic feeding of steel shot. It can quickly and continuously feed steel shot to the designated position, which is convenient for subsequent continuous heat treatment of steel shot. This automatic feeding system can be integrated with other heat treatment equipment to form a complete automated production line, which greatly improves work efficiency and reduces the direct contact between operators and high-temperature heat treatment equipment, reducing the safety risks of burns and scalds.

[0026] During the heat treatment of steel shot, after the steel shot is placed into the positioning groove 21 on the placement plate 18, the protective ring 20 prevents the steel shot from falling off the placement plate 18. The second motor 15 is started, causing the drive gear 16 to rotate, which in turn forces the driven gear 14 to drive the rotating column 12 to rotate, causing the rotating disk 13 to rotate along with the steel shot. When the steel shot rotates to the heat treatment mechanism, the pneumatic cylinder 17 operates, causing the pneumatic rod to move the placement plate 18 and the steel shot upwards. When the steel shot moves into the coil 23, the power supply 24 is started, energizing the coil 23 to generate heat, thus heat-treating the steel shot. After heat treatment, the steel shot is then passed through the pneumatic cylinder... 17. The process is repeated, moving the steel shot from coil 23 into annular tube 26. Water pump 29 is started, and cold water from cold water tank 28 is transported to annular tube 26 through water pipe channel 30. The cold water is sprayed onto the surface of the steel shot through nozzle 27 in annular tube 26, thereby cooling the heated steel shot and completing the heat treatment of the steel shot. This significantly improves the hardness of the steel shot. With the cooperation of automatic feeding mechanism and rotating mechanism, the entire heat treatment process can be carried out intermittently and continuously. This means that while one steel shot is undergoing heat treatment, the next steel shot is ready to be put into the designated position, thus achieving efficient, continuous and high-quality production.
