Description

Technical Field

[0001] The invention relates to the technical field of die casting polishing, and in particular to a polishing device for die casting processing. Background Art

[0002] Die casting is a kind of pressure casting part. The die casting machine uses the mold corresponding to the casting to pour the heated liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die casting machine. The die casting machine casts the parts of the shape and size limited by the mold. Such parts are usually called die castings. Due to factors such as the die casting machine, raw materials and die casting molds, the die castings will have residual traces such as flow marks, scratches and marks after the initial processing. At this time, the die castings need to be polished to reduce the surface roughness of the workpiece to obtain a bright and flat surface. Among them, the magnetic polishing machine used for the polishing process includes a control cabinet, a main box and an electromagnetic component. The electromagnetic component includes an electromagnetic coil that generates a magnetic field and a motor that drives the electromagnetic coil to rotate. The control cabinet controls the electromagnetic coil to form a magnetic field, adjusts the size and direction of the magnetic field, and the control cabinet controls the motor to drive the electromagnetic coil to rotate, thereby driving the magnetic needle to rotate in the barrel, thereby realizing the grinding and polishing of the surface of the die casting.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. A first polishing mechanism is provided. The first polishing mechanism drives the electromagnet to rotate through a disc, and guides the magnetic needle in the barrel to rotate. Compared with the prior art, which can only effectively polish the bottom of the die-casting, the disc and electromagnet located on the side are convenient for polishing the side of the die-casting and the top end near the side, which effectively increases the polishing range. Furthermore, an outer gear ring and a driving gear are provided to drive the mounting box to rotate along the outer gear ring, so as to polish each side and the corresponding top end of the die-casting, thereby providing a more efficient polishing efficiency.

[0030] 2. A second polishing mechanism is provided, including an electric push rod, a first ring plate, a first shaft, a second ring plate and a second shaft. The electric push rod pushes the bottom of the barrel, and the top of the barrel rotates around the first shaft or the second shaft to assist the barrel in deflection. After the barrel deflects, the die-casting inside deflects synchronously, so that the magnetic needle can more fully polish the top or side hole of the die-casting, reduce the area that is not fully polished, and effectively improve the polishing efficiency;

[0031] 3. A lifting and lowering assembly is provided, including two mounting rods for supporting the first ring plate and the second ring plate, as well as a main shaft body and a second driving part. The user can install a material barrel on the second ring plate on one side of the main chassis. The second driving part drives the main shaft body to rotate, drives the mounting rod to rotate, and then drives the material barrel to be placed in the working position. Compared with manually carrying the material barrel filled with polishing liquid, the lifting and lowering assembly can improve the handling efficiency of the material barrel, reduce the interval time of polishing multiple die-castings, and thus improve the polishing efficiency of the die-castings. Furthermore, a guide groove is provided, and the mounting rod can slide along the first channel and the second channel. The guide groove has an avoidance section, which can push the mounting rod to move, so that the material barrel avoids the frame, ensuring the stable installation of the material barrel, and the subsequent electromagnetic assembly can effectively guide the magnetic needle in the material barrel to rotate;

[0032] 4. A separation mechanism is provided, including a first filter, a second filter and a third filter, which can separate die-castings, magnetic needles, debris and waste liquid, so as to facilitate the rapid processing of materials in the barrel and reduce the interval time for polishing multiple die-castings. In addition, each filter is installed in a storage box, which can touch the barrel by pulling the storage box, guiding the barrel to rotate with the first axis as the axis, so that the mixed liquid in the barrel can be quickly poured into the storage box, further improving the processing efficiency.

[0033] To summarize, the second polishing mechanism adjusts the deflection of the material barrel and cooperates with the first polishing mechanism to guide the magnetic needle from the side to polish the die-casting, so that the specific surface of the die-casting can be fully polished to avoid the situation where the top and side holes of the die-casting are not fully polished; further, the rapid unloading of the landing assembly and the rapid processing of waste by the separation mechanism can reduce the interval time for polishing multiple die-castings, thereby improving the polishing efficiency of the die-castings.

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0055] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0056] Please refer to Figure 1 to Figure 12 The embodiment of the present invention provides a polishing device for die casting processing, comprising: a control cabinet 11, a main box 12 is provided on one side of the control cabinet 11, a frame 13 is provided on the top edge of the main box 12, an electromagnetic component 15 is provided inside the main box 12, a barrel 6 is provided at the top of the main box 12 corresponding to the electromagnetic component 15, the electromagnetic component 15 has a first axis, and its extension direction is a first direction, reference Figure 1 , the first direction is Figure 1 In the vertical direction, that is, the up and down direction, the control cabinet 11 controls the electromagnetic assembly 15 to form a magnetic field, and drives the magnetic needle in the barrel 6 to rotate. This is a prior art, and the principle is not repeated here. The main box 12 is provided with a first polishing mechanism 3 and a second polishing mechanism 4;

[0057] The first polishing mechanism 3 comprises:

[0058] The upper auxiliary part includes a first ring plate 33 connected to the main box 12 through a first shaft 31, the axis of the first shaft 31 extends in the second direction, the first ring plate 33 rotates around the first shaft 31, the bottom of the first ring plate 33 is rotatably connected to a second ring plate 37 through a second shaft 35, the second ring plate 37 rotates around the second shaft 35, the axis of the second shaft 35 extends in a direction perpendicular to the first direction, the barrel 6 is provided on the second ring plate 37, and a first gap is provided between the bottom end of the barrel 6 and the top end of the main box 12;

[0059] like Figure 3 , Figure 5 and Figure 6 As shown, when polishing is not performed, the axis of the second shaft body 35 extends in the left-right direction, and the second direction is Figure 1 In the front-to-back direction, that is, when the bottom end of the material barrel 6 is pushed forward or backward, the first ring plate 33 is restricted by the first shaft 31 and cannot swing in the front-to-back direction. Therefore, the material barrel 6 and the second ring plate 37 will swing and tilt with the second shaft 35 as the axis. When the bottom end of the material barrel 6 is pushed left or right, the second ring plate 37 is restricted by the second shaft 35 and cannot swing left and right. Therefore, the material barrel 6, the second ring plate 37 and the first ring plate 33 will swing and tilt with the first shaft 31 as the axis. Furthermore, during polishing, the magnetic needle can more fully contact the side hole or other recessed part of the die-casting, avoiding the situation of polishing supplement caused by the inability to move the die-casting. In addition, the first mounting plate 32 is provided at both ends of the top of the first ring plate 33 along the front-to-back direction. The two first mounting plates 32 are rotatably connected to the two first shafts 31 respectively, and second mounting plates 34 are provided at the bottom of the left and right ends of the first ring plate 33, and third mounting plates 36 are provided at the left and right ends of the top surface of the second ring plate 37. The second mounting plate 34 and the third mounting plate 36 at the same end are rotatably connected by the second shaft 35 to achieve the purpose of rotation of the second ring plate 37, and the outer edge diameter of the second ring plate 37 is smaller than the inner edge diameter of the first ring plate 33 to avoid collision between the two; further, the top end of the material barrel 6 is folded outward and extended to form a side ring 61, and the bottom end of the side ring 61 abuts against the top surface of the second ring plate 37 to achieve the installation of the material barrel 6, and two symmetrical second handles 62 are provided on the top of the material barrel 6 to facilitate the removal of the material barrel 6 from the second ring plate 37.

[0060] The lower pusher is disposed on the top of the main housing 12 and is used to push the bottom of the barrel 6 to move along the second direction or along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other;

[0061] like Figure 3 , Figure 5 and Figure 6 As shown, the third direction is Figure 1 In the left and right directions, the bottom of the barrel 6 is pushed by the lower pushing part, so that the barrel 6 swings under the cooperation of the upper auxiliary part.

[0062] In some embodiments, the lower push portion includes two fourth mounting plates 39 symmetrically arranged on the inner walls of both ends of the main box 12 along the second direction, and two fourth mounting plates 39 symmetrically arranged on the inner walls of both ends of the main box 12 along the third direction, and each fourth mounting plate 39 is installed with an electric push rod 310, and the four electric push rods 310 are respectively used to push the two ends of the bottom of the barrel 6 along the second direction and the two ends along the third direction;

[0063] like Figure 1 , Figure 3 and Figure 7 As shown, each fourth mounting plate 39 and the inner wall of the main case 12 have an angle with the opening facing downward, so that the electric push rod 310 is tilted, and the electric push rod 310 has stress on the horizontal plane when pushing the barrel 6, thereby avoiding the stress concentration in the vertical direction and causing the barrel 6 to be unable to be pushed; further, an inclined hole 38 is provided at the top of the main case 12 corresponding to the position of each electric push rod 310, so that the push rod of the electric push rod 310 can pass through the inclined hole 38 to push the bottom of the barrel 6, and a hemispherical soft block 311 is provided at the top of the push rod of the electric push rod 310 to avoid noise caused by the collision of the hard rod body with the barrel 6 and damage to the barrel 6.

[0064] In some embodiments, the second polishing mechanism 4 includes:

[0065] The magnetic assembly includes a mounting box body 43 disposed on one side of the barrel 6, a rotatable disc 49 is disposed inside the mounting box body 43, and the axis extension direction of the rotating shaft is perpendicular to the first direction. A plurality of electromagnets 412 are disposed near the end of the disc 49 near the barrel 6, and a driving member is also disposed on the mounting box body 43, and the driving member is used to drive the disc 49 to rotate, drive the electromagnets 412 to rotate, and guide the magnetic needle in the barrel 6 to rotate;

[0066] like Figure 2 and Fig. 9 As shown, the driving member can select a third motor 48, and the output shaft of the third motor 48 is connected to the center of the disc 49 to drive the disc 49 to rotate. When the electromagnet 412 is energized, it generates a magnetic force, which rotates with the disc 49 to guide the magnetic needle in the barrel 6 to one side of the die-casting and rotate, so as to grind and polish the side and the corresponding top of the die-casting. In the prior art, the magnetic needle is affected by the electromagnetic component 15 and only rotates at the bottom of the die-casting, that is, the bottom of the barrel 6. This limitation can be solved by the magnetic component, so that the magnetic needle can better grind the side and top of the die-casting. In addition, as shown in FIG. Fig.10 As shown, the electromagnets 412 are evenly distributed in two circles, with the same number but staggered arrangement, to ensure that the magnetic needles can be stably attracted.

[0067] A first driving unit, provided on the main chassis 12, for driving the magnetic assembly to rotate around a first axis;

[0068] like Figure 2 and Fig. 9 As shown, during grinding and polishing, the barrel 6 is coaxially arranged with the first axis, so that the magnetic component can rotate around the barrel 6, thereby grinding multiple side surfaces and corresponding top ends of the die casting, further reducing the ungrinded area and improving the polishing efficiency.

[0069] In some embodiments, the magnetic assembly further includes a conductive slip ring 410 disposed inside the mounting box 43, the stator of the conductive slip ring 410 is connected to the mounting box 43, the rotor of the conductive slip ring 410 is connected to the disc 49, the input end of the electromagnet 412 is electrically connected to the output end of the rotor of the conductive slip ring 410, and the input end of the stator of the conductive slip ring 410 is electrically connected to the output end of the control cabinet 11;

[0070] like Figure 2 and Fig.10 As shown, first, the magnitude and direction of the current input to the electromagnet 412 are controlled by the control cabinet 11, so as to control the magnitude and direction of the magnetic field of the electromagnet 412, so as to better control the rotation of the magnetic needle. In addition, by setting the conductive slip ring 410, it is ensured that the disc 49 and each electromagnet 412 can also be energized during rotation, and the wire entanglement and breakage are avoided. Furthermore, due to the effective volume of the conductive slip ring 410, it can be connected to the disc 49 as a whole through the rotor, and a connecting tube 411 is set at the stator end, and the other end of the connecting tube 411 is connected to the inner wall of the mounting box body 43, so as to fix the stator and rotate the rotor.

[0071] In some embodiments, the first driving unit includes an outer gear ring 41 disposed on the top of the main housing 12 and coaxially arranged with the electromagnetic assembly 15, a second motor 46 is disposed at the end of the mounting box 43 away from the barrel 6, and a driving gear 47 is sleeved outside the output shaft of the second motor 46, and the driving gear 47 is meshed with the teeth of the outer gear ring 41;

[0072] Two symmetrical T-shaped limit rods 44 are provided at the bottom of the installation box body 43, and a T-shaped ring groove 42 is provided at the top of the main box 12. The two T-shaped limit rods 44 are slidably arranged on the inner wall of the T-shaped ring groove 42, and the outer edge of the cross section of the T-shaped limit rod 44 is matched with the inner edge of the cross section of the T-shaped ring groove 42;

[0073] like Figure 2 and Fig. 9As shown, when the second motor 46 is started, the driving gear 47 rotates. Since the second motor 46 is arranged on the mounting box body 43, the driving gear 47 will roll along the outer gear ring 41, thereby driving the mounting box body 43 to rotate with the first axis as the axis. The input ends of the conductive slip ring 410, the third motor 48, the second motor 46, the first motor 252 and the electric push rod 310 are all connected to the output end of the control cabinet 11. The programming of the control method is the same as that of the control electromagnetic component 15, which will not be repeated here. Optionally, the mounting box body 43 is located at the rear end of the barrel 6 for initial In the initial state, the installation box body 43 can be rotated half a circle to the left or half a circle to the right to avoid cross-interference between the line and the barrel 6; the two T-shaped limit rods 44 move along the T-shaped ring groove 42, and cooperate with the active gear 47 to mesh with the teeth of the outer gear ring 41 to ensure that the installation box body 43 can stably rotate around the barrel 6. Furthermore, a rotatable auxiliary gear 45 is sleeved on the two T-shaped limit rods 44, and the auxiliary gear 45 meshes with the outer gear ring 41, which plays a further auxiliary role and improves the stability of the installation box body 43 during movement.

[0074] In some embodiments, the main chassis 12 is further provided with a lifting and lowering mechanism 2, and the lifting and lowering mechanism 2 includes:

[0075] The mounting portion includes two main shaft bodies 21 provided at both ends of the frame 13 along the second direction. The two main shaft bodies 21 can rotate, and the axis extension direction is the second direction. The two main shaft bodies 21 are slidably connected with mounting rods 22. One end of each mounting rod 22 is connected to the first shaft body 31, and the other end is connected to the limited slider 23;

[0076] The second driving part 25 is disposed on the top of the main chassis 12 and is used to drive the main shaft body 21 to rotate;

[0077] The two guide parts are respectively arranged on the two end surfaces of the main chassis 12 along the second direction, and are used to guide the limit slider 23 to move and drive the installation rod 22 to slide when the main shaft body 21 rotates.

[0078] like Figure 1 and Figure 5As shown, since the first mounting plate 32 is located at the front end and the rear end of the first ring plate 33, the two first shafts 31 corresponding to the first ring plate 33 are respectively connected to the mounting rod 22 at the front end and the mounting rod 22 at the rear end, and the first ring plate 33 is supported by the two corresponding mounting rods 22; the main shaft body 21 is started to rotate by the second driving part 25, driving the mounting rod 22 to rotate, and then the barrel 6 arranged on the second ring plate 37 will move synchronously with the first shaft body 31 and the first ring plate 33. When the mounting rod 22 is in a horizontal state, the barrel 6 is placed on the second ring plate 37, and the second driving part 25 is started to rotate. The dynamic main shaft body 21 rotates, driving the mounting rod 22 to rotate, and the barrel 6 arranged on the second ring plate 37 will move synchronously with the first shaft body 31 and the first ring plate 33. When the mounting rod 22 swings to a vertical state, the barrel 6 arranged on the second ring plate 37 will be placed on the top of the main case 12, and a first gap is formed between the bottom end of the barrel 6 and the top of the main case 12, so as to achieve the purpose of quickly placing the barrel 6 and facilitate subsequent grinding and polishing. After grinding is completed, the second driving part 25 starts the main shaft body 21 to rotate, driving the mounting rod 22 to rotate back to a horizontal state. No manual handling is required, and loading and unloading can be achieved more quickly.

[0079] In some embodiments, the guide portion is a guide groove 24 , and the guide groove 24 is formed by sequentially combining a limiting tail section 241 , an avoidance section 242 , a working section 243 , an avoidance section 242 and a limiting tail section 241 .

[0080] like Figure 1 and Figure 4 As shown, if the mounting rod 22 is of a fixed length, an excessively long mounting rod 22 will cause a larger distance between the material barrel 6 and the top surface of the main case 12, while an excessively short mounting rod 22 will cause the material barrel 6 to collide with the frame 13. Therefore, a guide groove 24 is provided. When the main shaft body 21 rotates, it will drive the mounting rod 22 to rotate, and one end of the mounting rod 22 is connected to a limiting slider 23. The limiting slider 23 will move sequentially along the limiting tail section 241, the avoidance section 242, and the working section 243. After passing through the avoidance section 242, the limiting slider 23 will drive the mounting rod 22 to move obliquely upward first, and then return to the original track, so that the material barrel 6 avoids the frame 13, thereby ensuring the stable installation of the material barrel 6, and the subsequent electromagnetic component 15 can effectively guide the rotation of the magnetic needle in the material barrel 6.

[0081] In some embodiments, the second driving unit 25 includes a first motor 252 disposed at the top of the main chassis 12, a worm 253 is disposed on the outer sleeve of the output shaft of the first motor 252, a worm wheel 255 is coaxially disposed at one end of the main shaft body 21, and the worm 253 is meshingly connected with the worm wheel 255.

[0082] like Figure 8As shown, a connecting shaft 254 is provided at the end of the main shaft body 21 near the electromagnetic component 15, and a worm gear 255 is sleeved on the outside of the connecting shaft 254. The worm 253 is driven to rotate by the first motor 252, and the worm 253 drives the worm gear 255 to rotate, thereby driving the connecting shaft 254 and the main shaft body 21 to rotate, thereby achieving the purpose of driving the main shaft body 21 to rotate. In addition, this transmission method has the function of reducing speed and increasing torque, that is, avoiding the main shaft body 21 from rotating too fast, and ensuring that there is sufficient stress to rotate the main shaft body 21; in addition, a mounting seat 251 is provided at the top of the main housing 12, and the first motor 252 is installed on the mounting seat 251, that is, the first motor 252 is connected to the main housing 12 through the mounting seat 251, which is convenient for the disassembly and assembly of the first motor 252, and ensures that the position of the output shaft of the first motor 252 and the worm 253 corresponds to the position of the worm gear 255.

[0083] In some embodiments, each main shaft body 21 is provided with a first channel 211 and a second channel 212 perpendicular to the first channel 211 , and a mounting rod 22 is slidably disposed inside the first channel 211 and the second channel 212 ;

[0084] like Figure 4 and Figure 8 As shown, mounting rods 22 are slidably provided in the first channel 211 and the second channel 212, and the extension directions of the two mounting rods 22 on the same main shaft body 21 are perpendicular to each other. Since the guide groove 24 is formed by the limiting tail section 241, the avoidance section 242, the working section 243, the avoidance section 242 and the limiting tail section 241, which are arranged in sequence, when one mounting rod 22 places the material barrel 6 on the top of the main case 12, the other mounting rod 22 places the material barrel 6 on the left or right side of the main case 12. The user can take away the material barrel 6, or put the die-casting and magnetic needles into the material barrel 6 and wait for the next processing.

[0085] In some embodiments, a separation mechanism 5 is provided at the bottom of the main chassis 12, and the separation mechanism 5 includes:

[0086] The connecting part includes a concave frame 51 disposed at the bottom end of the main chassis 12, and a middle partition plate 52 is disposed in the middle of the concave frame 51;

[0087] The movable part includes two storage boxes 53 arranged on both sides of the middle partition plate 52 along the third direction. The two storage boxes 53 can move away from or approach each other along the third direction. A plurality of filter assemblies 56 are arranged inside the two storage boxes 53 along the first direction. Each filter assembly 56 is used to separate the die castings, magnetic needles, debris and waste liquid.

[0088] like Figure 3 and Fig.11As shown, a first handle 54 is provided on the side of the storage box 53 away from the middle partition plate 52. After grinding is completed, the second driving part 25 starts the rotation of the main shaft body 21, drives the mounting rod 22 to rotate back to a horizontal state, pulls the first handle 54 to pull the storage box 53 toward the side away from the middle partition plate 52, and the storage box 53 touches the material barrel 6, causing the material barrel 6 to rotate with the first shaft body 31 as the axis. After tilting, the die-castings, magnetic needles, debris and waste liquid inside are poured into the storage box 53, and are filtered and separated by each filter assembly 56, thereby speeding up the efficiency of removing the die-castings and separating the waste chips, and solving the problem that the prior art requires multiple separations and has low separation efficiency; in addition, the four legs 14 originally arranged at the bottom of the main chassis 12 are installed at the bottom of the concave frame 51 to play a supporting role.

[0089] In some embodiments, three filter screen assemblies 56 are arranged inside the storage box 53 from bottom to top, each filter screen assembly 56 includes a mounting frame 562, the outer wall of each mounting frame 562 is in contact with the inner wall of the storage box 53, and the bottom of the three mounting frames 562 from bottom to top are respectively provided with a first filter screen 57, a second filter screen 58 and a third filter screen 59, and the apertures of the first filter screen 57, the second filter screen 58 and the third filter screen 59 increase in sequence;

[0090] like Fig.11 and Fig.12 As shown, the mixture poured into the storage box 53 will be filtered for the first time by the third filter 59. The third filter 59 has the largest aperture and is used to intercept the die-castings, while other objects will continue to fall downward through the pores to the second filter 58. The aperture of the second filter 58 is smaller than the length of the magnetic needles, so most of the magnetic needles will be intercepted by the second filter 58. Finally, the waste mixed with the waste liquid passes through the second filter 58 and flows to the first filter 57. The aperture of the first filter 57 is the smallest and is used to intercept the waste and the magnetic needles passing through the second filter 58, allowing the waste liquid to flow into the storage box 53, thereby achieving the purpose of separating the die-castings, magnetic needles, debris and waste liquid. The magnetic needles on the second filter 58 can be rinsed and put into use again, which is faster than the existing cleaning and separation. The mixture intercepted by the first filter 57 is uniformly stored and processed, and does not need to be processed every time. In addition, a drain valve 55 is provided at the bottom end of the storage box 53 away from the middle partition plate 52, and the waste liquid can be discharged after the hose is installed.

[0091] In some embodiments, columns 561 are provided at the four corners of the bottom of each installation frame 562, and limiting grooves 510 are provided at the four corners of the storage box 53. A limiting block 564 is provided at the bottom of each column 561. Each limiting block 564 is inserted into the limiting groove 510 or another installation frame 562. Along the first direction, the depth of the limiting groove 510, the thickness of the installation frame 562, and the thickness of the limiting block 564 are equal;

[0092] like Fig.11 and Fig.12As shown, the four corresponding limit blocks 564 under a mounting frame 562 can be inserted into the four limit grooves 510 to serve as the bottom filter assembly 56, while the four limit blocks 564 of the middle filter assembly 56 respectively abut against the top surface of the first filter 57 of the bottom filter assembly 56, and the corresponding bottom surface is supported by the top surfaces of four columns 561. The columns 561 separate the distance between adjacent mounting frames 562 to avoid the situation where the distance between adjacent mounting frames 562 is too small to facilitate the retention of debris or waste residue. In addition, part of the outer wall of the four limit blocks 564 abuts against the inner wall of the mounting frame 562 of the bottom filter assembly 56 to ensure that the installation of the middle filter assembly 56 is stable and avoids shaking during filtration. The installation method of the upper filter assembly 56 can be obtained in the same way. Furthermore, a plurality of lifting rings 563 are provided at the top of the mounting frame 562 to facilitate the user to lift the filter assembly 56 and quickly recycle the intercepted materials.

[0093] Use process, reference Figure 1 to Figure 12 :

[0094] Step 1: Reference Figure 1 In the initial state, there is already a material barrel 6 disposed on the second ring plate 37, located above the main box 12, which is recorded as the first material barrel 6, and another material barrel 6 is placed on the second ring plate 37 on one side of the main box 12, which is recorded as the second material barrel 6;

Similarly, start and reset the corresponding electric push rod 310 in a clockwise order to achieve multi-directional swing of the first barrel 6;

[0097] Step 4: After all the electric push rods 310 have been pushed, the electromagnetic assembly 15 is turned off, and then the second motor 46 is started. The second motor 46 drives the driving gear 47 to roll along the outer gear ring 41, driving the installation box 43 to move clockwise to the front end, and then the second motor 46 is turned off to serve as the initial position;

[0098] Step 5: Start the third motor 48 to drive the disc 49 to rotate, and supply power to the electromagnet 412 to generate magnetic force, so that the rotating disc 49 and the electromagnet 412 generate a magnetic field to guide the magnetism to grind and polish the side of the die casting, start the second motor 46 to reverse, and drive the installation box body 43 to rotate counterclockwise. After the installation box body 43 rotates one circle, the side surfaces of all the die castings are polished and polished.

[0099] Step 6: When the second motor 46 is reversed, that is, when the mounting box body 43 rotates counterclockwise, the corresponding electric push rod 310 can be started to extend and retract through the control cabinet 11. The started electric push rod 310 will not interfere with the rotating mounting box body 43, and the side hole and the top end of the die casting can be polished more fully;

[0100] Step 7: After polishing is completed, the second motor 46 is started to rotate forward to drive the mounting box 43 to reset, and the third motor 48 is turned off to wait for the next operation;

[0101] Step 8: Start the first motor 252, which is connected to the worm 253 through the worm gear 255, drives the main shaft 21 to rotate, and then drives the mounting rod 22 to rotate. Figure 4 , the limiting slider 23 corresponding to the mounting rod 22 connected to the first material barrel 6 moves from the working section 243 to the right to the avoidance section 242, and moves from the avoidance section 242 to the limiting tail section 241 on the right, so as to move the first material barrel 6 to the right side of the main box 12 to prepare for the subsequent separation process, and the limiting slider 23 corresponding to the mounting rod 22 connected to the second material barrel 6 moves from the limiting tail section 241 on the left to the avoidance section 242, and moves from the avoidance section 242 to the middle working section 243, so as to place the second material barrel 6 on the main box 12 to wait for the grinding and polishing operation;

[0102] Step 9: Pull the first handle 54 of the left storage box 53, the storage box 53 will push the bottom of the first material barrel 6 to the left, so that the first material barrel 6 swings, and the mixed liquid and materials inside are poured into the storage box 53 along the opening, and the corresponding die castings, magnetic needles, debris and waste liquid are separated through the first filter 57, the second filter 58 and the third filter 59;

[0103] Step 10, take out the separated materials from the storage box 53 and store them in categories, then reset the storage box 53, and then reload the die-casting, magnetic needles and polishing liquid into the first barrel 6, waiting for the next process. In the process of processing the storage box 53 and the first barrel 6, repeat steps 2 to 6. At this time, the second barrel 6 replaces the position of the first barrel 6 to achieve polishing of the die-casting in the second barrel 6;

[0104] Step eleven, after the die casting in the second barrel 6 is polished and ground, the second barrel 6 and the first barrel 6 are restored to their original positions. The principle is similar to that of steps eight to nine and will not be described in detail here.
