Description

Technical Field

[0001] This utility model relates to the field of wear-resistant steel ball processing technology, specifically a wear-resistant steel ball grinding equipment. Background Technology

[0002] The production of steel balls mainly includes the following steps: drawing of raw materials, cold heading, grinding, heat treatment, strengthening, hard grinding, preliminary grinding, flaw detection, cleaning, rust removal, and packaging. In all these processes, whether it's grinding, hard grinding, or preliminary grinding, a grinding machine is needed to treat the ball surface, remove the ring-like bands on the surface of the ball blank, improve the surface quality and shape of the steel ball, and ultimately achieve a final improvement.

[0003] In the processing of wear-resistant steel balls, in order to improve the processing quality, the wear-resistant steel balls need to be ground. Existing high-precision steel ball grinding processes often suffer from poor grinding quality and low work efficiency. For example, patent application number 201821288388.X discloses a steel ball grinding machine, which solves the problems of low automation and low work efficiency. However, it has the problems of not being able to perform multiple grinding processes on wear-resistant steel balls, high difficulty in grinding steel balls, and the inability to recycle the grinding fluid.

[0004] Therefore, we propose a wear-resistant steel ball grinding device. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of existing wear-resistant steel ball grinding devices, such as the inability to perform multiple grinding processes on wear-resistant steel balls, the difficulty of grinding steel balls, and the inability to recycle the grinding fluid. The invention provides a wear-resistant steel ball grinding device with a reasonable structural design, capable of multiple grinding processes on wear-resistant steel balls, with low grinding difficulty, and without the inability to recycle the grinding fluid.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] A wear-resistant steel ball grinding device includes a grinding fluid tank, a grinding roller, a pump, and a drive mechanism. The grinding fluid tank is equipped with a column, and a filter screen is vertically installed inside the tank. A top plate is located at the top of the column. The filter screen filters the grinding fluid in the tank, facilitating the pump's extraction of the filtered fluid. This prevents impurities in the grinding fluid from damaging the pump and improves the grinding quality of the wear-resistant steel balls. The top plate includes a fixing ring, a grinding cylinder, a lifting cylinder, a feed pipe, and a drive mechanism. A baffle roller is installed on the inner wall of the grinding cylinder, and a feeding hopper is installed at the bottom of the grinding cylinder. The feeding hopper is connected to the top side wall of the lifting cylinder through a discharge pipe. The top of the lifting cylinder is connected to the grinding cylinder through a return pipe, and a sealing cover is movably installed at the bottom of the lifting cylinder. A fixed shaft is installed at the top of the grinding roller. The grinding roller is placed inside the grinding cylinder, and the top of the fixed shaft passes through a fixed ring and is connected to the drive structure. Wear-resistant steel balls are added into the grinding cylinder through the feed pipe. The drive structure drives the grinding roller to rotate, and the grinding roller drives the wear-resistant steel balls to rotate. The grinding steel balls rotate inside the grinding cylinder, causing the grinding rollers to drive the wear-resistant steel balls to roll between the guide rollers and the grinding rollers, thus thoroughly grinding the wear-resistant steel balls. After grinding, the wear-resistant steel balls flow with the grinding fluid into the feeding hopper, and then through the discharge pipe into the bottom of the lifting cylinder. The wear-resistant steel balls rise along the inner wall of the lifting cylinder and flow back into the grinding cylinder through the return pipe for further grinding. This achieves the purpose of multiple-cycle grinding of the wear-resistant steel balls, improving the grinding quality. The infusion pump is installed on the top plate, and a [missing information - likely a device or component] is installed on the infusion pump. It has a suction pipe and a delivery pipe. The suction pipe is connected to the grinding slurry tank, and the delivery pipe is connected to the grinding cylinder. The delivery pump draws out the grinding slurry through the suction pipe and delivers it to the grinding cylinder through the delivery pipe and connecting pipe. This lubricates and grinds the wear-resistant steel balls during the grinding process, which reduces the grinding difficulty of the wear-resistant steel balls and enhances the grinding quality. The grinding slurry flows into the lifting cylinder along with the wear-resistant steel balls and then flows back to the grinding slurry tank from the bottom of the lifting cylinder, realizing the circulation of the grinding slurry and reducing waste.

[0008] Preferably, the number of filter screens in the grinding fluid tank is set to 3-6 layers, and the mesh size of each filter screen increases sequentially from one end to the other. The infusion pump draws out the grinding fluid through the suction pipe and delivers it to the grinding cylinder through the infusion pipe to lubricate and grind the wear-resistant steel balls during the grinding process. The grinding fluid flows into the lifting cylinder along with the wear-resistant steel balls and flows back into the grinding fluid tank from the bottom of the lifting cylinder, realizing the circulation of the grinding fluid. The multi-layer filter screen can filter the grinding fluid in the grinding tank, which can not only prevent impurities in the grinding fluid from damaging the infusion pump, but also improve the grinding quality of the wear-resistant steel balls and reduce the waste of grinding fluid.

[0009] Preferably, the top of the baffle roller on the inner wall of the grinding cylinder is configured with a high outer and low inner structure. The wear-resistant steel ball raw material to be ground is fed into the grinding cylinder through the feed pipe. The wear-resistant steel ball rolls quickly from the top of the baffle roller to between the baffle roller and the grinding roller, so that the grinding roller can fully grind the wear-resistant steel ball between the baffle roller and the grinding roller, which can also improve the grinding efficiency of the wear-resistant steel ball. The baffle roller is configured with a high outer and low inner structure to avoid wear-resistant steel ball residue at the top of the baffle roller.

[0010] Preferably, the drive mechanism includes a motor, a fixed rod is provided on the top plate, a fixed plate is provided on the fixed rod, the motor is provided on the fixed plate, a drive shaft is provided on the motor, the drive shaft extends vertically into the lifting cylinder, a drive wheel is provided at the top of the drive shaft, and a driven wheel is provided at the top of the fixed shaft. The driven wheel is connected to the drive wheel via a belt. The motor drives the drive shaft to rotate, the drive shaft drives the drive wheel to rotate, and the drive wheel drives the driven wheel and the fixed shaft to rotate via a belt. This causes the fixed shaft to drive the grinding roller to rotate inside the grinding cylinder, which facilitates the grinding roller to perform sufficient grinding treatment on the wear-resistant steel balls.

[0011] Preferably, the top of the grinding roller is configured with a spherical structure. The wear-resistant steel ball raw material to be ground is fed into the grinding cylinder through the feed pipe. The wear-resistant steel ball rolls along the top surface of the grinding roller to the surface of the grinding roller and the baffle roller, avoiding the wear-resistant steel ball residue on the top of the grinding roller, thereby improving the grinding efficiency and grinding quality of the wear-resistant steel ball.

[0012] Preferably, the drive shaft inside the lifting cylinder is equipped with a spiral lifting plate, and a scraper is provided at the bottom of the drive shaft. The ground wear-resistant steel balls flow into the feeding hopper with the grinding liquid, and then flow into the bottom of the lifting cylinder through the discharge pipe. The grinding liquid at the bottom of the lifting cylinder is discharged through the discharge hole on the sealing cover. The drive shaft drives the lifting plate and scraper to rotate. The scraper scrapes up the wear-resistant steel balls at the bottom of the sealing cover. The rotating lifting plate pushes the wear-resistant steel balls upward. The wear-resistant steel balls rise along the inner wall of the lifting cylinder and flow back into the grinding cylinder from the return pipe to continue grinding. This achieves the purpose of multiple grinding treatments of the wear-resistant steel balls, improving the grinding quality of the wear-resistant steel balls. The scraper is inclined on the drive shaft so that the scraper rotating with the drive shaft can scrape up the wear-resistant steel balls in the sealing cover, which facilitates the upward movement of the wear-resistant steel balls in the lifting cylinder under the action of the lifting plate. This facilitates the rapid return of the wear-resistant steel balls to the grinding cylinder for continued grinding, enhancing the grinding quality of the wear-resistant steel balls.

[0013] Preferably, the sealing cap and the lifting cylinder are connected by threads, and a discharge hole is provided on the sealing cap. During the grinding process of the wear-resistant steel balls, the sealing cap is connected to the lifting cylinder, and the wear-resistant steel balls enter the lifting cylinder with the grinding liquid. The discharge hole on the sealing cap allows the grinding liquid to separate the impurities carried by it from the wear-resistant steel balls. The wear-resistant steel balls rise in the lifting cylinder and flow back into the grinding cylinder for further grinding, thereby improving the grinding quality of the wear-resistant steel balls.

[0014] Preferably, the infusion pump has a connecting pipe on its infusion tube, and the fixed shaft is a hollow structure with a drain hole on the bottom side wall. The connecting pipe extends vertically into the hollow fixed shaft. The infusion pump draws out the grinding liquid through the suction pipe and delivers it to the grinding cylinder through the infusion tube and connecting pipe. This lubricates and grinds the wear-resistant steel balls during the grinding process, reducing the grinding difficulty and improving the grinding quality. The grinding liquid flows into the lifting cylinder along with the wear-resistant steel balls and then flows back to the grinding liquid tank from the bottom of the lifting cylinder, achieving the circulation of the grinding liquid and reducing waste.

[0015] Preferably, a sealing ring is provided between the outer wall of the connecting pipe and the inside of the fixed shaft, and the bottom of the hollow fixed shaft is set as an arc-shaped structure. The sealing ring can improve the sealing between the connecting pipe and the fixed shaft, prevent the grinding fluid that has entered the fixed shaft from overflowing from the top of the fixed shaft, and allow the grinding fluid to fully enter the grinding cylinder to fully grind the wear-resistant steel balls. The arc-shaped structure of the bottom of the fixed shaft can prevent the grinding fluid from remaining in the hollow fixed shaft, thereby reducing the waste of grinding fluid.

[0016] Beneficial effects:

[0017] 1. The grinding fluid at the bottom of the lifting cylinder is discharged through the impurity discharge hole on the sealing cover. The drive shaft drives the lifting plate and scraper to rotate. The scraper scrapes up the wear-resistant steel balls at the bottom of the sealing cover. The rotating lifting plate pushes the wear-resistant steel balls upward. The wear-resistant steel balls rise along the inner wall of the lifting cylinder. The wear-resistant steel balls flow back into the grinding cylinder from the return pipe to continue grinding. This achieves the purpose of grinding the wear-resistant steel balls multiple times and improves the grinding quality of the wear-resistant steel balls.

[0018] 2. The wear-resistant steel balls that need to be ground are fed into the grinding cylinder through the feed pipe. The wear-resistant steel balls roll along the top surface of the grinding roller to the surface of the grinding roller and the retaining roller, so as to avoid the wear-resistant steel balls leaving residue on the top of the grinding roller, thereby improving the grinding efficiency and grinding quality of the wear-resistant steel balls.

[0019] 3. The infusion pump draws the grinding fluid through the suction pipe and delivers it to the grinding cylinder through the infusion pipe to lubricate and grind the wear-resistant steel balls during the grinding process. The grinding fluid flows into the lifting cylinder along with the wear-resistant steel balls and then flows back to the grinding fluid tank from the bottom of the lifting cylinder, realizing the circulation of the grinding fluid. The multi-layer filter screen can filter the grinding fluid in the grinding chamber, which can not only prevent impurities in the grinding fluid from damaging the infusion pump, but also improve the grinding quality of the wear-resistant steel balls and reduce the waste of grinding fluid.

[0029] As attached Figure 1-5As shown, a wear-resistant steel ball grinding device includes a grinding fluid tank 1, a grinding roller 2, and a pump 3. A column 4 is mounted on the grinding fluid tank 1. A filter screen 5 is vertically installed inside the grinding fluid tank 1. A top plate 6 is mounted on the top of the column 4. A fixing ring 7, a grinding cylinder 8, a lifting cylinder 9, a feed pipe 10, and a drive structure are mounted on the top plate 6. A baffle roller 11 is installed on the inner wall of the grinding cylinder 8. A discharge bin 12 is located at the bottom of the grinding cylinder 8 and is connected to the top side wall of the lifting cylinder 9 via a discharge pipe 13. The top of the lifting cylinder 9 is connected to the grinding cylinder 8 through the return pipe 14, and a sealing cover 15 is movably installed at the bottom of the lifting cylinder 9. The top of the grinding roller 2 is provided with a fixed shaft 24. The grinding roller 2 is placed inside the grinding cylinder 8, and the top of the fixed shaft 24 passes through the fixed ring 7 and is connected to the drive structure. The infusion pump 3 is installed on the top plate 6. The infusion pump 3 is provided with a suction pipe 28 and an infusion pipe 29. The suction pipe 28 is connected to the grinding liquid tank 1, and the infusion pipe 29 is connected to the grinding cylinder 8.

[0030] The grinding fluid tank 1 contains 3 layers of filter screens 5, with the mesh size of each filter screen 5 increasing sequentially from one end to the other. The top of the baffle roller 11 on the inner wall of the grinding cylinder 8 is designed to be higher on the outside and lower on the inside.

[0031] The drive mechanism includes a motor 19, a fixed rod 17 on the plate, a fixed plate 18 on the fixed rod 17, a motor 19 on the fixed plate 18, a drive shaft 20 on the motor 19, the drive shaft 20 extending vertically into the lifting cylinder 9, a drive wheel 21 on the top of the drive shaft 20, a driven wheel 25 on the top of the fixed shaft 24, and the driven wheel 25 connected to the drive wheel 21 via a belt 27. The top of the grinding roller 2 is a spherical structure.

[0032] The material lifting cylinder 9 has a spiral lifting plate 22 on the drive shaft 20 and a scraper 23 at the bottom of the drive shaft 20.

[0033] The sealing cover 15 is connected to the material lifting cylinder 9 by a thread, and a discharge hole 16 is provided on the sealing cover 15.

[0034] The infusion pump 3 has a connecting pipe 30 on its infusion tube 29, a hollow structure on its fixed shaft 24, a drain hole 26 on the bottom side wall of the fixed shaft 24, and the connecting pipe 30 is vertically inserted into the hollow fixed shaft 24. A sealing ring 31 is provided between the outer wall of the connecting pipe 30 and the inside of the fixed shaft 24, and the bottom of the hollow fixed shaft 24 is set as an arc-shaped structure.

[0035] Example 2:

[0036] Further explanation is provided based on Example 1, as shown in the appendix. Figure 6As shown, a wear-resistant steel ball grinding device has grinding strips 32 on the surface of the grinding roller 2, which are arranged in a spiral structure. The wear-resistant steel balls in the grinding cylinder 8 enter between the baffle roller 11 and the grinding roller 2 under the action of the rotating grinding roller 2. The grinding roller 2 drives the wear-resistant steel balls to roll between the baffle roller 11 and the grinding roller 2, which fully grinds the wear-resistant steel balls. The grinding strips 32 can separate the wear-resistant steel balls, preventing a large number of wear-resistant steel balls from gathering together and improving the grinding efficiency of the wear-resistant steel balls. On the other hand, the spiral structure of the grinding strips 32 pushes the wear-resistant steel balls downward, so that the ground wear-resistant steel balls fall into the feeding bin 12, which facilitates the rapid return of the wear-resistant steel balls to the grinding cylinder 8 for circulation grinding. This not only enhances the grinding efficiency of the wear-resistant steel balls, but also improves the grinding quality of the wear-resistant steel balls.

[0037] Working principle: The sealing cap 15 is installed at the bottom of the lifting cylinder 9. The multi-layer filter screen 5 is installed in the grinding liquid tank 1. Grinding liquid is poured into the grinding liquid tank 1. The motor 19 is started, and the motor 19 drives the transmission shaft 20 to rotate. The transmission shaft 20 drives the drive wheel 21, the lifting plate 22, and the scraper 23 to rotate. The drive wheel 21 drives the driven wheel 25 and the fixed shaft 24 to rotate through the belt 27, thereby causing the fixed shaft 24 to drive the grinding roller 2 to rotate in the grinding cylinder 8. The infusion pump 3 is started, and the infusion pump 3 draws out the grinding liquid through the suction pipe 28. The grinding liquid is then transported to the hollow fixed shaft 24 through the infusion pipe 29 and the connecting pipe 30, and discharged from the drain hole 26 at the bottom of the fixed shaft 24. The grinding liquid flows along the surface of the grinding roller 2. The wear-resistant steel ball raw material to be ground is fed into the grinding cylinder 8 through the feed pipe 10, so that the wear-resistant steel ball is ground between the baffle roller 11 and the grinding roller 2. The wear-resistant steel balls, after contacting the grinding fluid on the surface of the grinding roller 2, flow into the feeding hopper 12 with the grinding fluid and then into the bottom of the lifting cylinder 9 through the discharge pipe 13. The grinding fluid at the bottom of the lifting cylinder 9 is discharged through the impurity discharge hole 16 on the sealing cover 15. The drive shaft 20 drives the lifting plate 22 and scraper 23 to rotate. The scraper 23 scrapes up the wear-resistant steel balls at the bottom of the sealing cover 15, and the rotating lifting plate 22 pushes the wear-resistant steel balls upward. The wear-resistant steel balls rise along the inner wall of the lifting cylinder 9 and flow back into the grinding cylinder 8 through the return pipe 14 for further grinding. After the wear-resistant steel balls have been circulated and ground multiple times, the sealing cover 15 on the lifting cylinder 9 is opened, and the wear-resistant steel balls in the grinding cylinder 8 fall into the lifting cylinder 9 through the feeding hopper 12 and the discharge pipe 13 and are discharged from the bottom of the lifting cylinder 9. The ground wear-resistant steel balls are collected, the power is cut off, and the impurities remaining in the grinding cylinder 8, the lifting cylinder 9, and the grinding fluid tank 1 are cleaned.
