Description

Technical Field

[0001] This invention relates to the field of wear-resistant ball processing technology, specifically to a metal wear-resistant ball surface grinding device. Background Technology

[0002] Metal wear-resistant balls are a type of grinding media widely used in ball mills in industries such as mining, cement and building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemicals, coal-water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, and quartz sand. Their main function is to crush and grind materials.

[0003] In the manufacturing process of metal wear-resistant balls, grinding is an important industrial process that involves surface treatment and fine machining of the metal wear-resistant balls to improve their wear resistance and performance.

[0004] In the grinding process of metal wear-resistant balls, the wear-resistant balls first need to be cleaned and pre-treated to remove surface dirt and impurities. Then, appropriate grinding equipment and grinding media are selected, and grinding is carried out according to the material and specifications of the wear-resistant balls.

[0005] During the grinding process, the wear-resistant balls rub and collide with the grinding media, thereby removing uneven parts and minor defects from the surface.

[0006] In the prior art, when grinding metal wear-resistant balls, it is necessary to improve the contact quality between the metal wear-resistant balls and the grinding workpiece in order to improve the quality of the final product. Furthermore, when processing large batches of products, the grinding device needs to have high processing efficiency. Therefore, this invention proposes a surface grinding device for metal wear-resistant balls. Summary of the Invention

[0007] The purpose of this invention is to provide a metal wear-resistant ball surface grinding device.

[0008] The technical problem solved by this invention is: how to improve the contact quality between the metal wear-resistant ball and the grinding part in order to improve the quality of the final product, and how to improve the processing efficiency during processing.

[0009] The present invention can be achieved by the following technical solution: a metal wear-resistant ball surface grinding equipment, including an inclined grinding box, a feeding box and a discharging box are respectively installed at the upper and lower ends of the grinding box, a detachable first storage box is installed at the bottom of the discharging box, and a detachable second storage box is installed at the bottom of the grinding box;

[0010] During operation, the metal wear-resistant balls to be ground enter from the feed box. Some of the metal wear-resistant balls are confined in the grinding box, while the remaining metal wear-resistant balls enter the discharge box and fall into the first collection box for recycling. After subsequent collection, they are reintroduced into the grinding box through the feed box.

[0011] A grinding component is installed at the top inside the grinding box, and a positioning component is installed below the grinding component inside the grinding box. A filling plate is installed outside the positioning component inside the grinding box. The upper surface of the filling plate is flush with the upper surface of the positioning component, and the upper surfaces of the filling plate and the positioning component are both located below the connection between the grinding box and the feeding box. After the grinding box enters the grinding box through the feeding box, it slides along the positioning component.

[0012] The positioning component includes a device frame, inside which a storage plate is installed via multiple connecting rods, and inside which a positioning frame is installed via multiple fourth-stroke cylinders. When not in use, the positioning frame is stored inside the storage plate. During grinding, the fourth-stroke cylinders are activated to lift the positioning frame upward.

[0013] A third-stroke cylinder is installed at the bottom of the equipment rack. The output end of the third-stroke cylinder faces upward and is equipped with a second drive mechanism. A bottom liner is installed at the output end of the second drive mechanism. After the second drive mechanism is started, it drives the bottom liner to rotate eccentrically on the underside of the storage plate.

[0014] A further technical improvement of the present invention is that: the grinding assembly includes a plurality of first-stroke cylinders connected to the top of the inside of the grinding box, the output end of each first-stroke cylinder is downward and is equipped with a first driving mechanism;

[0015] A grinding element is installed at the output end of the first drive mechanism. After the first drive mechanism is started, it drives the grinding element to rotate.

[0016] A further technical improvement of the present invention is that: the storage plate includes a connecting frame, and the connecting frame has multiple positioning grooves inside, each positioning groove being used to limit a group of metal wear-resistant balls;

[0017] The upper surface of the connecting frame is provided with a storage slot on the outside of each positioning slot.

[0018] A further technical improvement of the present invention is that: when not in use, the positioning frame is embedded in the storage slot of the storage plate, and the upper surface of the positioning frame is not higher than the upper surface of the connecting frame;

[0019] The positioning frame includes multiple positioning rings, each positioning ring being sleeved on the outside of each positioning slot in the storage plate, and an assembly frame is installed between each positioning ring, the assembly frame being connected to each fourth stroke cylinder.

[0020] The shape of the storage slot matches the various positioning rings and assembly racks.

[0021] A further technical improvement of the present invention is that: the bottom liner frame includes a base frame, the upper surface of the base frame is equipped with a plurality of protrusions, each protrusion is located on the lower side of a set of positioning grooves, and a barrier strip is installed between the side of each protrusion and the lower surface of the connecting frame.

[0022] The barrier strip separates the gap between the protrusion and the corresponding positioning groove;

[0023] After the second drive mechanism is activated, the base frame drives each protrusion to rotate eccentrically on the underside of the storage plate, thereby causing the metal wear-resistant balls to rotate.

[0024] A further technical improvement of the present invention is that: a first swing mechanism is installed on both sides inside the grinding box, the output ends of the two sets of the first swing mechanism are connected to the equipment frame, and the output ends of the two sets of the first swing mechanism are coaxially distributed;

[0025] After the two sets of first swing mechanisms are started, the equipment frame swings. Then the third stroke cylinder in the positioning assembly is started, raising the protrusion into the corresponding positioning groove and lifting the metal wear-resistant ball out of the positioning groove, thus facilitating the transfer of the metal wear-resistant ball from the positioning assembly.

[0026] A further technical improvement of the present invention is that: a plurality of second-stroke cylinders are installed inside the grinding box on the lower side of the equipment frame, and a support is installed at the output end of each second-stroke cylinder;

[0027] When the equipment frame is parallel to the grinding workpiece, each second-stroke cylinder is activated, moving the support to the underside of the equipment frame to support the equipment frame.

[0028] Before the equipment frame swings based on the two sets of first swing mechanisms, each support component moves to the outside of the equipment frame's movement path via a second stroke cylinder, thereby avoiding contact with the equipment frame when it moves.

[0029] A further technical improvement of the present invention is that a moving component is installed on the side of the grinding box, and the moving direction of the output end of the moving component is the same as the moving direction of the metal wear-resistant ball inside the grinding box.

[0030] The output end of the moving component is equipped with a buffer component. After the moving component is started, it drives the buffer component to move along the upper side of the positioning component to reduce the speed at which the metal wear-resistant ball moves along the positioning component.

[0031] A further technical improvement of the present invention is that: the buffer assembly includes a second swing mechanism, a connecting part is installed on the side of the second swing mechanism facing the moving assembly, the connecting part is used to connect to the output end of the moving assembly, and a baffle is installed on the other side of the second swing mechanism;

[0032] After the buffer assembly moves to the end of the grinding box facing the discharge box based on the moving assembly, the second swing mechanism swings the baffle, and the metal wear-resistant balls pass through the underside of the baffle and fall into the discharge box.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In the present invention, when grinding metal wear-resistant balls, a certain number of metal wear-resistant balls are limited by a positioning component and kept within a fixed range during grinding. In addition, the rotation of the bottom liner in the positioning component allows each metal wear-resistant ball to make better contact with the grinding component, thereby improving the grinding quality of the metal wear-resistant balls.

[0035] Furthermore, by passing a batch of metal wear-resistant balls through the positioning component, the present invention can limit the movement of a batch of metal wear-resistant balls at once, collect the unlimited metal wear-resistant balls, and re-screen the remaining metal wear-resistant balls in the subsequent process, thereby maintaining high processing efficiency. Moreover, when the metal wear-resistant balls pass through the positioning component, the moving component and the buffer component can reduce the moving speed of the metal wear-resistant balls, thereby facilitating better contact between the metal wear-resistant balls and the positioning component.

[0043] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0044] Please see Figure 1-5 As shown, a metal wear-resistant ball surface grinding equipment includes an inclined grinding box 1, a feed box 2 and a discharge box 3 installed at the upper and lower ends of the grinding box 1 respectively, a detachable first storage box 4 installed at the bottom of the discharge box 3, and a detachable second storage box 5 installed at the bottom of the grinding box 1.

[0045] During operation, the metal wear-resistant balls to be ground enter from the feed box 2. Some of the metal wear-resistant balls are confined in the grinding box 1, and the remaining metal wear-resistant balls enter the discharge box 3 and fall into the first collection box 4 for recycling. After subsequent collection, they re-enter the grinding box 1 through the feed box 2.

[0046] A grinding component is installed at the top inside the grinding box 1, and a positioning component 9 is installed inside the grinding box 1 below the grinding component. A filling plate 10 is installed inside the grinding box 1 outside the positioning component 9. The upper surface of the filling plate 10 is flush with the upper surface of the positioning component 9, and the upper surfaces of the filling plate 10 and the positioning component 9 are both located below the connection between the grinding box 1 and the feed box 2. After the grinding box 1 enters the grinding box 1 through the feed box 2, it slides along the positioning component 9.

[0047] The positioning component 9 includes a device frame 91. Inside the device frame 91, a storage plate 93 is installed via multiple connecting rods 92. Inside the device frame 91, a positioning frame 98 is installed via multiple fourth-stroke cylinders 97. When not in use, the positioning frame 98 is stored inside the storage plate 93. During grinding, the fourth-stroke cylinders 97 are activated to lift the positioning frame 98 upward.

[0048] A third-stroke cylinder 94 is installed at the bottom of the equipment rack 91. The output end of the third-stroke cylinder 94 faces upward and is equipped with a second drive mechanism 95. A bottom liner 96 is installed at the output end of the second drive mechanism 95. After the second drive mechanism 95 is started, it drives the bottom liner 96 to rotate eccentrically on the underside of the storage plate 93.

[0049] A moving component 11 is installed on the side of the grinding box 1. The moving direction of the output end of the moving component 11 is the same as the moving direction of the metal wear-resistant ball inside the grinding box 1.

[0050] Please see Figure 2 As shown, a buffer component 12 is installed at the output end of the moving component 11. After the moving component 11 is started, it drives the buffer component 12 to move along the upper side of the positioning component 9 to reduce the speed at which the metal wear-resistant ball moves along the positioning component 9.

[0051] The grinding assembly includes multiple first-stroke cylinders 6 connected to the top of the inside of the grinding box 1. The output end of each first-stroke cylinder 6 faces downward and is equipped with a first drive mechanism 7.

[0052] A grinding element 8 is installed at the output end of the first drive mechanism 7. After the first drive mechanism 7 is started, it drives the grinding element 8 to rotate.

[0053] Both sides of the inside of the grinding box 1 are equipped with a first swing mechanism 13. The output ends of the two sets of first swing mechanisms 13 are connected to the equipment frame 91, and the output ends of the two sets of first swing mechanisms 13 are coaxially distributed.

[0054] After the two sets of first swing mechanisms 13 are started, the equipment frame 91 is swung. Then the third stroke cylinder 94 in the positioning component 9 is started, raising the protrusion 962 into the interior of the corresponding positioning groove 932, and lifting the metal wear-resistant ball out of the positioning groove 932, thereby facilitating the transfer of the metal wear-resistant ball from the positioning component 9.

[0055] Inside the grinding box 1, a number of second-stroke cylinders 14 are installed on the lower side of the equipment frame 91, and a support 15 is installed at the output end of each second-stroke cylinder 14.

[0056] When the equipment frame 91 is parallel to the grinding workpiece 8, each second stroke cylinder 14 is activated, moving the support member 15 to the lower side of the equipment frame 91, and supporting the equipment frame 91 through the support member 15.

[0057] Before the equipment rack 91 swings based on the two sets of first swing mechanisms 13, each support member 15 moves to the outside of the movement path of the equipment rack 91 through the second stroke cylinder 14, thereby avoiding contact with the equipment rack 91 when it moves.

[0058] Please see Figure 3-4As shown, the storage plate 93 includes a connecting frame 931, and the connecting frame 931 has multiple positioning grooves 932 inside, each positioning groove 932 being used to limit a set of metal wear-resistant balls;

[0059] The upper surface of the connecting bracket 931 is provided with a storage slot 933 on the outside of each positioning slot 932.

[0060] When not in use, the positioning bracket 98 is embedded in the storage slot 933 of the storage plate 93, and the upper surface of the positioning bracket 98 is not higher than the upper surface of the connecting bracket 931.

[0061] The positioning frame 98 includes multiple positioning rings 982, each positioning ring 982 is respectively sleeved on the outside of each positioning groove 932 in the storage plate 93, and an assembly frame 981 is installed between each positioning ring 982, the assembly frame 981 is connected to each fourth stroke cylinder 97.

[0062] The shape of the storage slot 933 matches the individual positioning rings 982 and assembly racks 981.

[0063] The base frame 96 includes a base frame 961. A plurality of protrusions 962 are mounted on the upper surface of the base frame 961. Each protrusion 962 is located on the lower side of a set of positioning grooves 932, and a barrier strip 963 is installed between the side of each protrusion 962 and the lower surface of the connecting frame 931.

[0064] The barrier strip 963 separates the gap between the protrusion 962 and the corresponding positioning groove 932;

[0065] After the second drive mechanism 95 is started, the base frame 961 drives each protrusion 962 to rotate eccentrically on the lower side of the storage plate 93, thereby driving the metal wear-resistant ball to rotate.

[0066] Please see Figure 5 As shown, the buffer assembly 12 includes a second swing mechanism 121. A connecting part 122 is installed on the side of the second swing mechanism 121 facing the moving assembly 11. The connecting part 122 is used to connect to the output end of the moving assembly 11, and a baffle 123 is installed on the other side of the second swing mechanism 121.

[0067] After the buffer assembly 12 moves to the end of the grinding box 1 facing the discharge box 3 based on the moving assembly 11, the second swing mechanism 121 swings the baffle 123, and the metal wear-resistant balls pass through the underside of the baffle 123 and fall into the discharge box 3.

[0068] When using this invention, the metal wear-resistant balls to be ground are poured into the feed box 2, and at the same time the moving component 11 moves the buffer component 12 to the side of the grinding box 1 facing the feed box 2.

[0069] And after the metal wear-resistant balls enter the grinding box 1, the moving component 11 drives the buffer component 12 to slide along the filling plate 10 and the positioning component 9. When the metal wear-resistant balls move on the positioning component 9, if there is a positioning groove 932 on the path, a group of metal wear-resistant balls will fall into the positioning groove 932, and the bottom of the metal wear-resistant balls will contact the corresponding protrusion 962.

[0070] After the buffer assembly 12 moves to the end of the grinding box 1 facing the discharge box 3, the second swing mechanism 121 is activated, swinging the baffle 123 toward the discharge box 3. The metal wear-resistant balls that have not fallen into the positioning groove 932 move from the underside of the baffle 123 to the discharge box 3 and are collected in the first storage box 4.

[0071] Subsequently, each fourth-stroke cylinder 97 is activated, driving the positioning frame 98 to move upward. After the positioning frame 98 moves upward, the positioning ring 982 is fitted onto the outer side of the corresponding metal wear-resistant ball. Then, the first-stroke cylinder 6 is activated, driving the first drive mechanism 7 and the grinding part 8 to descend. After the grinding part 8 descends to the preset height, the first drive mechanism 7 is activated, driving the grinding part 8 to rotate and grind the metal wear-resistant ball. At the same time, the second drive mechanism 95 is activated, driving the bottom liner 96 to rotate. After the bottom liner 96 rotates, it drives the metal wear-resistant ball to rotate from the bottom. When the metal wear-resistant ball rotates, the positioning ring 982 can limit the movement range of the metal wear-resistant ball.

[0072] After grinding, the grinding part 8 is reset, and at the same time, each second stroke cylinder 14 is activated to retract the support 15. Then, the first swing mechanism 13 is activated to swing the positioning component 9 downward.

[0073] Then the third stroke cylinder 94 starts, driving the bottom liner 96 to rise until the protrusion 962 in the bottom liner 96 is embedded in the corresponding positioning groove 932, pushing out the metal wear-resistant balls in each positioning groove 932. The pushed-out metal wear-resistant balls fall into the second storage box 5.

[0074] Finally, the first swing mechanism 13 resets the positioning component 9, and each support 15 moves back to the lower side of the positioning component 9 based on the corresponding second stroke cylinder 14.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
