Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a grinding device for metal powder processing of wire saw alloys. Background Technology

[0002] Metal powder grinding in wire saw alloy machining is a process that transforms waste materials or alloy materials generated during wire saw alloy machining into metal powder and then grinds them into finer powder. After the processed alloy scraps and other raw materials are initially treated into small particles, grinding equipment is used to reduce the size of the particles under the action of extrusion and friction, turning them into finer powder. This is of great significance for the recycling of metal materials and the production of powder products that meet specific particle size requirements, and can be used in the manufacture of metal products and to improve resource utilization.

[0003] The wire saw alloy machining metal powder grinding device is a specialized unit that converts waste or alloy materials generated during wire saw alloy machining into metal powder. This device utilizes grinding equipment to continuously reduce particle size through mechanical actions such as extrusion and friction between particles, ultimately obtaining finer metal powder. It plays a crucial role in metal material recycling and production, enabling the efficient preparation of metal powder.

[0004] In some existing wire saw alloy processing metal powder grinding devices, some metal powder is not sufficiently ground and directly enters the collection component when the metal powder is discharged, resulting in uneven metal powder size, which reduces the production quality of metal powder and increases production costs. Therefore, a wire saw alloy processing metal powder grinding device is proposed to solve the above problems. Utility Model Content

[0007] A wire saw alloy processing metal powder grinding device includes four legs. A collection box is slidably connected to one end of each leg. A dual-head motor is slidably connected to the front end of the collection box. A drive shaft is fixedly connected to the drive end of each dual-head motor. A swing shaft is rotatably connected to the outside of the drive shaft. A fixed sleeve is rotatably connected to the rear end of the swing shaft. A disc frame is fixedly connected to the adjacent ends of two fixed sleeves. A sieve disc is fixedly connected inside the disc frame. Four swing sleeves are rotatably connected to the outside of the sieve disc. A fixed shaft is rotatably connected inside the swing sleeves. A grinding assembly is fixedly connected to the top of each leg. A feeding assembly is fixedly connected to the top of the grinding assembly.

[0010] As a further description of the above technical solution:

[0011] The grinding assembly includes a main frame, a grinding chamber fixedly connected inside the main frame, a second motor fixedly connected to the front end of the main frame, a gear fixedly connected to the drive end of the second motor, a grinding roller fixedly connected to the rear end of the gear, another grinding roller rotatably connected inside the main frame, another gear fixedly connected to the front end of the other grinding roller, a discharge port fixedly connected to the bottom end of the grinding chamber, and a protective cover fixedly connected to the front end of the main frame.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a dual-head motor drives the drive shaft to rotate, which in turn drives the swing shaft to rotate outside the fixed sleeve. At the same time, the swing shaft drives the fixed sleeve and the disc frame to swing back and forth. The disc frame drives the screen to swing back and forth. While the disc frame is swinging back and forth, it also drives the swing sleeve to swing back and forth. The swing sleeve rotates outside the fixed shaft to limit the movement of the disc frame. This screens the metal powder that falls into the disc frame from the bottom of the discharge port, leaving the larger metal powder particles at the top of the screen and allowing the smaller metal powder particles to fall into the collection box for collection. This achieves the effect of screening the produced metal powder.

[0024] 2. In this utility model, the feeding plate is driven by motor one to rotate inside the bracket and the feeding slope, so as to send the blocked raw material into the inside of the feeding port. At this time, hydraulic press one is started, and hydraulic press one drives the pressure plate to move downward. At the same time, the pressure plate slides downward inside the feeding port, pushing the raw material accumulated inside the feeding port into the inside of the main frame through the opening at the top of the main frame, thereby achieving the effect of preventing raw material blockage.

[0031] 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 protection scope of the present utility model.

[0032] Reference Figures 1 to 2 This utility model provides an embodiment of a wire saw alloy processing metal powder grinding device, including a leg frame 10. The leg frame 10 is welded from a sturdy steel structure, providing a solid support foundation for the entire device and ensuring that the device will not shake or shift during operation. A collection box 9 is slidably connected inside the leg frame 10. The collection box 9 is made of anti-static plastic material, which effectively prevents metal powder from being adsorbed onto the box wall due to static electricity, facilitating the collection and cleaning of metal powder. A dual-head motor 1 is slidably connected to the front end of the collection box. The dual-head motor 1 can stably output power, ensuring the continuous operation of the entire device. A drive shaft 2 is fixedly connected to the drive end of each dual-head motor 1. The drive shaft 2 is made of high-strength alloy steel, whose material properties allow it to withstand large torsional and impact forces, effectively transmitting the power of the dual-head motor 1 and ensuring the coordinated movement of subsequent components. A swing shaft 3 is rotatably connected to the outside of the drive shaft 2. The swing shaft 3 is connected to the drive shaft 2 using a precision bearing connection. This connection method reduces friction loss, makes rotation smoother, and improves the mechanical efficiency of the device.

[0033] The rear end of the swing shaft 3 is rotatably connected to a fixed sleeve 4. The fixed sleeve 4 is made of durable stainless steel, which has good corrosion resistance and can maintain structural stability in complex working environments, providing a reliable connection base. A disc frame 5 is fixedly connected to one end of each of the two fixed sleeves 4. The disc frame 5 is made of high-strength aluminum alloy, which is lightweight and strong, easy to install and disassemble, and maintains good stability during swinging. A sieve disc 6 is fixedly connected inside the disc frame 5. The sieve disc 6 is made of wear-resistant alloy, has high precision and is not easily deformed, and can accurately classify and screen metal powder to ensure product quality. Four swing sleeves 7 are rotatably connected to the outside of the sieve disc 6. The swing sleeves 7 are made of stainless steel and coated with lubricating oil inside, which reduces the coefficient of friction with related components, reduces component wear, and extends the maintenance cycle of the device.

[0034] The swing sleeve 7 has an internal rotating connection to a fixed shaft 8, which is made of cast steel and has extremely high hardness and rigidity, providing stable support and accurate positioning for the swing of the disc frame 5.

[0035] Reference Figure 1 and Figure 3The feeding assembly includes a hydraulic press 13, which precisely controls pressure to ensure stable feeding of raw materials without damaging the equipment due to excessive pressure. A pressure plate 14 is fixedly connected to the drive end of the hydraulic press 13. The pressure plate 14 is made of high-quality, high-strength alloy steel with a special wear-resistant surface treatment. This not only withstands significant pressure but also effectively reduces friction with the raw materials, extending its service life and ensuring a stable and reliable feeding action. A hydraulic frame 12 is fixedly connected to the bottom end of the hydraulic press 13. The hydraulic frame 12 adopts a robust welded steel structure, possessing excellent stability and load-bearing capacity. It provides a stable mounting foundation for the hydraulic press 13 and other related components, preventing shaking or displacement during operation.

[0036] The hydraulic frame 12 has a fixed internal feed inlet 15, which is made of stainless steel with a smooth inner wall. This material effectively prevents raw materials from adhering, ensuring smooth entry. Its reasonable structural design guides the raw materials accurately to subsequent components. A feed ramp 16 is fixedly connected to the front end of the feed inlet 15. The feed ramp 16 is made of stainless steel with a certain inclination angle. This angle helps the raw materials slide smoothly under their own weight, and the stainless steel material avoids contamination of the raw materials while reducing frictional resistance. A motor 18 is fixedly connected to the left end of the feed ramp 16. The motor 18 provides stable power output, driving the feed plate 17 to rotate, allowing for continuous operation over extended periods.

[0037] A feeding plate 17 is fixedly connected to the drive end of motor 18. The feeding plate 17 is made of lightweight aluminum alloy and has multiple evenly distributed push plates on its surface. The aluminum alloy material reduces its weight, making it easier for motor 18 to drive. The push plates effectively push the raw material inside the feeding ramp 16 into the feed inlet 15. A bracket 19 is fixedly connected to the right end of the feeding ramp 16. The bracket 19 is made of high-strength carbon steel and has a robust structure, providing stable support for the feeding ramp 16 and ensuring that its position remains fixed throughout the feeding process. The bottom end of the hydraulic frame 12 is fixedly connected to the top of the grinding assembly, ensuring the tightness and stability of the connection between the feeding assembly and the grinding assembly, allowing the raw material to smoothly transition from the feeding stage to the grinding stage.

[0038] Reference Figures 2 to 4The grinding assembly includes a main frame 11, which is welded from high-strength steel. This robust material and welding process give it excellent stability and load-bearing capacity, firmly supporting the other components of the grinding assembly and ensuring that there is no shaking or deformation during the grinding process, providing a reliable basic structure for the grinding work. A grinding chamber 20 is fixedly connected inside the main frame 11. The grinding chamber 20 is made of smooth and wear-resistant stainless steel. Its smooth inner wall effectively reduces the adhesion of metal powder during the grinding process, allowing the raw material and ground powder to flow smoothly within the chamber. The wear-resistant properties ensure that the chamber wall will not be easily worn down during long-term grinding operations, thus maintaining a good grinding environment and effect. A second motor 22 is fixedly connected to the front end of the main frame 11. The second motor 22 provides strong and stable power to drive the rotation of the subsequent components. A gear 23 is fixedly connected to the drive end of motor 22. Gear 23 is made of high-quality alloy steel and precision-machined, possessing high-precision tooth profiles and excellent meshing performance, enabling accurate and reliable transmission of power from motor 22. A grinding roller 21 is fixedly connected to the rear end of gear 23. Grinding roller 21 is made of high-hardness tungsten carbide alloy with a special wear-resistant surface treatment. This material allows the grinding roller 21 to easily crush metal materials during grinding, while also possessing strong wear resistance, maintaining good grinding performance for extended periods and effectively improving grinding efficiency. Another grinding roller 21, also made of high-hardness tungsten carbide alloy, is rotatably connected inside the main frame 11. The two grinding rollers 21 work together, rotating in opposite directions to thoroughly grind the raw materials inside the grinding chamber 20. The distance between them can be adjusted appropriately according to the required particle size of the metal powder to achieve the best grinding effect.

[0039] Another grinding roller 21 is fixedly connected to a gear 23 at its front end. Like the previous gear 23, it has precise transmission performance, ensuring that the two grinding rollers 21 can rotate synchronously and stably to complete the grinding task together. A discharge port 24 is fixedly connected to the bottom of the grinding chamber 20. The discharge port 24 has an inverted trapezoidal structure and is made of stainless steel with a smooth inner wall. Its smooth inner wall and structural design help the ground metal powder to be smoothly discharged from the grinding chamber 20, avoiding blockage and ensuring the smooth progress of the entire grinding process. A protective cover 25 is fixedly connected to the front end of the main frame 11. The protective cover 25 is made of transparent high-strength plastic. On the one hand, it protects components such as the motor 22 and gear 23 from external dust and impurities, preventing them from affecting their normal operation. On the other hand, its transparency allows operators to observe the operation of the internal components at any time, so as to detect and deal with problems in a timely manner. The sieve disc 6 has sieve holes inside, the size of which is precisely designed to accurately sieve the metal powder according to the required particle size. Large particles of metal powder that do not meet the requirements remain at the top of the sieve disc 6, while small particles that meet the requirements pass smoothly through the sieve holes, ensuring that the final metal powder has a uniform particle size. The far end of the fixed shaft 8 is fixedly connected to the near end of the leg frame 10. This connection method prevents the swing sleeve 7 from shifting during rotation. The left and right ends of the feeding plate 17 are rotatably connected to the inside of the feeding ramp 16. This rotatable connection method allows the feeding plate 17 to rotate flexibly within the feeding ramp 16, thereby better utilizing the drive of the motor 18 to effectively push the raw material inside the feeding ramp 16 into the feed inlet 15 via the surface pusher plate, ensuring smooth feeding of the raw material.

[0040] A bracket 19 is rotatably connected to the right end of the feeding plate 17. The bracket 19 provides a stable support point for the rotation of the feeding plate 17, ensuring that the feeding plate 17 will not deviate or shake during rotation, maintaining its stable function of pushing raw materials. The bottom end of the hydraulic frame 12 is fixedly connected to the top end of the main frame 11. This tight connection ensures the integrity and stability between the feeding component and the grinding component, allowing the raw material to smoothly enter the grinding component for subsequent grinding operations after passing through the feeding stage. The bottom end of the motor 18 is fixedly connected to the top end of the protective cover 25, making the installation position of the motor 18 in the device stable, and also facilitating its effective cooperation with other related components to ensure the smooth progress of the feeding process. The bottom end of the main frame 11 is fixedly connected to the top end of the leg frame 10, further enhancing the stability of the entire device. The leg frame 10 provides solid support for the grinding component, preventing the main frame 11 from shaking or tilting due to vibration or other reasons during the grinding process. The bottom end of the bracket 19 is fixedly connected to the top end of the protective cover 25, making the bracket 19 and the protective cover 25 tightly connected. Together, they provide strong support for the rotation of the feeding plate 17 and the stability of the feeding ramp 16, ensuring the normal operation of the feeding process. The left end of gear 23 and the right end of another gear 23 are meshed. This precise meshing connection ensures accurate power transmission, allowing the two gears 23 to rotate synchronously, thereby driving the two grinding rollers 21 to rotate synchronously and in opposite directions, performing efficient grinding of the raw materials inside the grinding chamber 20. The grinding chamber 20 has an internal cavity, which provides sufficient space for grinding the metal raw materials, allowing the raw materials to be fully ground under the action of the grinding rollers 21. It also facilitates the flow of powder generated during the grinding process within the cavity, which is eventually discharged through the discharge port 24.

[0041] Working principle: When metal powder needs to be ground, the worker pours the raw material into the inside of the feed ramp 16, starts the motor 18, and drives the feeding plate 17 to rotate. The feeding plate 17 pushes the raw material inside the feed ramp 16 into the feed inlet 15 through the push plate on its surface. At this time, the hydraulic press 13 is started. The hydraulic press 13 drives the pressure plate 14 to slide downward inside the feed inlet 15 while pushing the raw material to the subsequent components.

[0042] When the raw material feed inlet 15 enters the grinding chamber 20, the second motor 22 is started. The second motor 22 drives the gear 23 to rotate inside the main frame 11. The gear 23 drives another gear 23 to rotate through meshing connection. Both gears 23 drive a grinding roller 21 to rotate inside the main frame 11. While the two grinding rollers 21 are rotating, they grind the raw material inside the grinding chamber 20. After grinding, the metal powder enters the subsequent components from the bottom of the grinding chamber 20 through the discharge port 24.

[0043] When the metal powder enters the interior of the disc frame 5, the dual-head motor 1 is started. The dual-head motor 1 drives the drive shaft 2 to rotate, the drive shaft 2 drives the swing shaft 3 to rotate, the swing shaft 3 drives the fixed sleeve 4 to move back and forth, the fixed sleeve 4 drives the disc frame 5 to swing back and forth, the disc frame 5 drives the sieve disc 6 to swing back and forth, and the disc frame 5 simultaneously drives the swing sleeve 7 to rotate outside the fixed shaft 8. The fixed shaft 8 supports and limits the disc frame 5 through the fixed connection between it and the leg frame 10. While the sieve disc 6 swings back and forth, it sieves the metal powder inside the disc frame 5, so that the large metal powder particles that do not meet the requirements remain at the top of the sieve disc 6, and the small metal powder particles that meet the requirements pass through the sieve holes inside the sieve disc 6.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
