Description

Technical Field

[0001] This invention relates to the field of engine intake manifold technology, and in particular to an automatic forming equipment and method for an impact-resistant engine intake manifold. Background Technology

[0002] The intake manifold is located between the throttle body and the engine intake valve. It is called a manifold because after the air enters the throttle body and passes through the manifold buffer system, the air flow channels branch off here. Corresponding to the number of engine cylinders, for example, a four-cylinder engine has four channels, and a five-cylinder engine has five channels, which guide the air into each cylinder. In order to reduce gas flow resistance and improve intake capacity, the inner wall of the intake manifold should be made sufficiently smooth during manufacturing.

[0003] However, in actual use, the inventors found that the inner wall of the intake manifold formed by casting has many burrs and is not clean and smooth enough, which affects the intake efficiency. Furthermore, since the intake manifold has various passages connected to the main body, its internal structure is complex, which makes it easy to encounter technical problems such as low grinding efficiency, large differences in grinding quality, and low degree of automation when manually polishing it later. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by setting up a transfer mechanism and a grinding mechanism to work together to perform targeted grinding work on the main pipe and branch pipe parts of the intake manifold. At the same time, it ensures the continuity of the grinding process, improves efficiency, and effectively solves the technical problems of many burrs on the inner wall of the intake manifold formed by casting, and the inner wall is not clean and smooth enough, which affects the intake efficiency. Furthermore, because the intake manifold has various passages connected to the main body, its internal structure is complex, which easily leads to low grinding efficiency, large differences in grinding quality, and low degree of automation when grinding manually in the future.

[0005] To address the above technical problems, the following technical solution is adopted: An automatic forming equipment for impact-resistant engine intake manifolds, comprising: a casting device, a cooling device, and a grinding device, wherein the grinding device includes:

[0006] A transfer mechanism is mounted on the chassis and is used to receive the intake manifold and drive it to perform subsequent processing work.

[0007] A sandblasting mechanism is mounted on the chassis and is used to sandblast and polish the inner wall of the intake manifold.

[0008] An auxiliary mechanism is installed on the chassis and is used to recover sand and control dust.

[0009] The sandblasting mechanism includes a sandblasting assembly mounted on the chassis for driving the sand to be sprayed out, a sealing assembly mounted on the sandblasting assembly for sealing one end of the air intake manifold, a directional adjustment assembly mounted on the chassis for changing the direction of the sand during the sandblasting process, a first rotating assembly mounted on the sandblasting assembly for driving the sealing assembly to adjust the direction, and a second rotating assembly mounted on the sandblasting assembly for adjusting the direction of the sand spraying before sandblasting.

[0010] Preferably, the transfer mechanism includes a receiving component mounted on the chassis for receiving and moving the intake manifold for processing, and a ventilation component mounted on the receiving component for adjusting the on / off states of multiple outlets of the intake manifold.

[0011] Preferably, the receiving assembly includes two sets of sprocket and chain drive components disposed on both sides of the chassis via a first rotating shaft, a first follower gear connected to the first rotating shaft, a first drive gear connected to the output end of the first motor and meshing with the two first follower gears respectively, and a plurality of receiving seats connected to the sprocket and chain drive components.

[0012] Preferably, the ventilation assembly includes multiple sealing posts connected to the receiving seat by a first spring, grooves formed on the sealing posts, and two sets of L-shaped rods connected to the chassis and corresponding to the sealing posts.

[0013] Preferably, the sandblasting assembly includes a reciprocating lead screw connected to the housing, bevel gears respectively connected to one end of the reciprocating lead screw and the output end of the first motor and meshing with each other, a first slider connected to the reciprocating lead screw and located in the first slide rail, a mounting bracket connected to the first slider via a second rotating shaft, a storage bin connected to the mounting bracket, an inner tube connected to the mounting bracket and communicating with the storage bin via a conduit, an outer tube connected to the inner tube and connected to the output end of the drive cylinder via a vertical plate, and a nozzle connected to the end of the outer tube.

[0014] Preferably, the sealing assembly includes a sealing plate connected to the outer tube, a ring connected to the sealing plate and connected to the mounting bracket via a second spring, a limiting block connected to the nozzle, and a limiting hole formed on the sealing plate.

[0015] The steering assembly includes a spiral section, a reset section, and a bending section that are opened on the outer tube and are interconnected, a second slide rail that is mounted on the mounting bracket and connected to a second slider, and a guide rod that is connected to the second slider and located in the bending section.

[0016] Preferably, the first rotating assembly includes a half gear connected to the second rotating shaft and two directional racks respectively connected to both sides of the chassis and meshing with the half gear.

[0017] The second rotating assembly includes a gear ring connected to the sealing plate and two sets of rotating racks respectively connected to both sides of the chassis and meshing with the gear ring for transmission.

[0018] Preferably, the auxiliary mechanism includes a recovery component mounted on the chassis for timely recovery of sand and a dust removal component mounted on the chassis for timely collection of fly ash.

[0019] Preferably, the recycling assembly includes two rollers connected to the chassis, a roll of fabric connected to the chassis and wound around one end of the rollers, and a second motor connected to the chassis and whose output end is connected to one end of the roll of fabric.

[0020] The dust removal assembly includes two sets of second drive gears connected to the reciprocating lead screw, two sets of second follower gears connected to the chassis via a third rotating shaft and meshing with the second drive gears, fan blades connected to the third rotating shaft, and a dust collector installed on the top of the chassis for dust removal.

[0021] A forming method for an automatic forming equipment for an impact-resistant engine intake manifold includes the following steps:

[0022] Step 1, main pipe polishing process: First, the intake manifold is placed on the receiving component and enters the chassis along the transmission direction. At this time, the sandblasting component is aligned with the opening of the intake manifold main pipe and moves synchronously with the receiving component. During the process, the sealing component seals the opening of the main pipe. The sandblasting component rotates continuously as it moves forward under the action of the directional component, thereby fully polishing the inner wall of the main pipe.

[0023] Step 2, the sub-pipe grinding process: when the sandblasting component moves backward, the directional component no longer restricts the direction of the sandblasting component. At this time, the sandblasting direction is aligned with the sub-pipe position and moves horizontally backward to grind the sub-pipe. Throughout the process, the ventilation component alternately opens multiple sub-pipe outlets, allowing the abrasive material to move in one direction, thereby enhancing the grinding effect.

[0024] Step 3, the turning process: After the intake manifold on one side is polished, the sandblasting assembly moves to one side of the chassis. Under the combined action of the first rotating assembly and the second rotating assembly, the sandblasting direction of the sandblasting assembly is adjusted. Then, the receiving assembly on the other side drives the lower intake manifold to move together with the sandblasting assembly to continue the polishing work.

[0025] Step four, recycling process: During the grinding process, the bottom recycling component quickly discharges the falling sand, and under the action of the dust removal component, the dust inside the chassis gathers from both sides to the middle and is discharged outwards for collection.

[0026] The beneficial effects of this invention are:

[0027] (1) In this invention, by setting up a sandblasting mechanism, which includes a sandblasting component, a sealing component, a directional component, a first rotating component and a second rotating component, the internal burrs can be removed and the inner wall polished quickly when the intake manifold is being sandblasted. This effectively solves the technical problem that manual sandblasting is prone to low sandblasting efficiency and large differences in sandblasting effect due to the complex structure of the intake manifold, and ensures the uniformity of the intake manifold production quality.

[0028] (2) In this invention, by setting the transfer mechanism and the grinding mechanism to work together, the problem that the original grinding device needs to be moved to the original position for reset after moving with the first set of intake manifolds and completing the grinding work is addressed, so that the grinding work of another set of intake manifolds can be carried out during the reset process, thereby increasing the full utilization of power resources.

[0029] (3) In this invention, by setting up ventilation components and directional components to cooperate with each other, the ventilation components open the pipe openings of each branch pipe in a targeted manner to guide the sand material to perform the grinding work one by one. Furthermore, by rotating the main pipe during grinding, the grinding effect on the inner wall of the main pipe is fully improved, thereby improving the overall grinding quality of the intake manifold.

[0030] (4) In this invention, by setting up a recycling component, the sand material that falls off during grinding is discharged, sorted and collected in time and then used in the spraying and grinding mechanism, thereby saving sand material and reducing the situation of excessive sand material accumulation and dust generation. In addition, the winding method effectively reduces damage to the bottom support object and extends the service life.

[0031] In summary, this equipment has the advantages of high working efficiency, strong continuity, and effective improvement of the grinding effect of the inner wall of the intake manifold, and is especially suitable for the field of engine intake manifold technology. Attached Figure Description

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] Example 1

[0051] like Figure 1-4 and Figure 7-8 As shown, an automatic forming device for an impact-resistant engine intake manifold 200 includes: a casting device, a cooling device, and a grinding device, wherein the grinding device includes:

[0052] Transfer mechanism 1 is mounted on the chassis 100 and is used to receive the intake manifold 200 and drive it to perform subsequent processing work.

[0053] A sandblasting mechanism 2 is mounted on the chassis 100 and is used to sandblast and polish the inner wall of the intake manifold 200.

[0054] Auxiliary mechanism 3 is installed on the casing 100 and is used to recover sand and control dust.

[0055] The sandblasting mechanism 2 includes a sandblasting assembly 21 mounted on the housing 100 for driving the sand to be sprayed out, a sealing assembly 22 mounted on the sandblasting assembly 21 for sealing one end of the air intake manifold 200, a directional adjustment assembly 23 mounted on the housing 100 for changing the direction of the sand during the sandblasting process, a first rotating assembly 24 mounted on the sandblasting assembly 21 for driving the sealing assembly 22 to adjust the direction, and a second rotating assembly 25 mounted on the sandblasting assembly 21 for adjusting the direction of the sand spraying before sandblasting.

[0056] In this embodiment, by setting up a sandblasting mechanism 2, which includes a sandblasting component 21, a sealing component 22, a directional component 23, a first rotating component 24, and a second rotating component 25, the internal burrs can be quickly removed and the inner wall polished when the intake manifold 200 is being sanded. This effectively solves the technical problem that manual sanding of the intake manifold 200 is prone to low sanding efficiency and large differences in sanding effect due to its complex structure, thus ensuring the uniformity of the production quality of the intake manifold 200.

[0057] In detail, firstly, the intake manifold 200 is mounted on the two-sided transfer mechanism 1 by a robotic arm. Then, the transfer mechanism 1 carries the intake manifold 200 into the chassis 100. At this time, the grinding mechanism 2 moves synchronously with the intake manifold 200 and begins grinding. After the grinding of one side of the intake manifold 200 is completed, the grinding mechanism 2 begins to turn and completes the grinding of the other set of intake manifolds 200 during the reset process. During the process, the auxiliary mechanism 3 collects and treats the dust inside the chassis 100 in a timely manner, and the sand that flows down from the bottom is discharged and reused in a timely manner.

[0058] Furthermore, such as Figure 1-4 As shown, the transfer mechanism 1 includes a receiving component 11 mounted on the chassis 100 for receiving and moving the intake manifold 200 for processing, and a ventilation component 12 mounted on the receiving component 11 for adjusting the on / off states of multiple outlets of the intake manifold 200.

[0059] In this embodiment, by setting the transfer mechanism 1 and the polishing mechanism 2 to work together, the problem of the original polishing device needing to move back to its original position for reset after moving with the first set of intake manifolds 200 and completing the polishing work is addressed. This allows the polishing work of another set of intake manifolds 200 to be carried out during the reset process, thereby increasing the full utilization of power resources.

[0060] In detail, the intake manifold 200 is first connected to the receiving component 11, and the intake manifold 200 is driven into the chassis 100 to move synchronously with the grinding mechanism 2 to carry out the grinding work. During the process, the ventilation component 12 opens the corresponding branch pipe ports in sequence to cooperate with the grinding mechanism 2 to carry out the grinding work.

[0061] Furthermore, such as Figure 1-4 As shown, the receiving component 11 includes two sets of sprocket and chain drive components 112 disposed on both sides of the housing 100 via a first rotating shaft 111, a first follower gear 113 connected to the first rotating shaft 111, a first drive gear 115 connected to the output end of the first motor 114 and meshing with the two first follower gears 113 respectively, and a plurality of receiving seats 116 connected to the sprocket and chain drive components 112.

[0062] In this embodiment, by setting two sets of sprocket and chain drive components 112 connected to both sides of the chassis 100, the input work of the intake manifold 200 is divided into two groups. Thus, the processing work of the intake manifold 200 in the corresponding moving direction can be completed during the back-and-forth movement of the grinding mechanism 2, so that the grinding mechanism 2 can make full use of power resources.

[0063] In detail, the first motor 114 drives the first follower gears 113 on both sides to rotate through the first drive gear 115 connected to the output end, and then drives the corresponding sprocket and chain transmission component 112 to rotate through the first rotating shaft 111, so that multiple receiving seats 116 start to operate and complete the installation of the intake manifold 200 with the help of the robotic arm.

[0064] It should be noted that the transmission directions of the two sprocket chain drive components 112 are opposite, and the installation times of the air intake manifolds 200 on the two bearing seats 116 are staggered, which are adapted to the back-and-forth operation of the grinding mechanism 2.

[0065] Furthermore, such as Figure 5-6 As shown, the ventilation assembly 12 includes a plurality of sealing posts 122 connected to the receiving seat 116 by a first spring 121, grooves 123 formed on the sealing posts 122, and two sets of L-shaped rods 124 connected to the chassis 100 and corresponding to the sealing posts 122.

[0066] In this embodiment, by setting up a ventilation component 12, the ventilation component 12 opens the openings of each branch pipe in a targeted manner, guiding the abrasive material to polish each branch pipe one by one.

[0067] In detail, during the movement of the receiving seat 116, multiple sealing columns 122 are moved. During the process, the grooves 123 at the bottom of the multiple sealing columns 122 contact and squeeze with the corresponding L-shaped rods 124 in sequence, thereby causing each branch pipe to open in sequence and guiding the sand material sprayed by the grinding mechanism 2 to be discharged. When the sealing column 122 separates from the corresponding L-shaped rod 124, it automatically resets under the action of the first spring 121.

[0068] It should be noted that the two sets of L-shaped rods 124 correspond to the two actions of extending and retracting the grinding mechanism 2, and the top of the sealing column 122 is set in a conical shape to prevent sand from staying.

[0069] Furthermore, such as Figure 3-4 and Figure 7-9 As shown, the sandblasting assembly 21 includes a reciprocating screw 211 connected to the housing 100, a bevel gear 212 connected to one end of the reciprocating screw 211 and the output end of the first motor 114 and meshing with each other, a first slider 214 connected to the reciprocating screw 211 and located in the first slide rail 213, a mounting bracket 216 connected to the first slider 214 via a second rotating shaft 215, a storage bin 217 connected to the mounting bracket 216, an inner tube 219 connected to the mounting bracket 216 and communicating with the storage bin 217 via a conduit 218, an outer tube 2112 connected to the inner tube 219 and connected to the output end of the drive cylinder 2111 via a vertical plate 2110, and a nozzle 2113 connected to the end of the outer tube 2112.

[0070] In this embodiment, by setting the reciprocating screw 211 in the sandblasting assembly 21 to be linked with the first motor 114, the full utilization of power resources is improved on the one hand, and the sandblasting assembly 21 can continuously complete the reciprocating movement under the drive of the reciprocating screw 211, and perform grinding work in conjunction with the bearing seats 116 on both sides.

[0071] In detail, firstly, the first motor 114 drives the reciprocating screw 211 to rotate via the bevel gear 212. The reciprocating screw 211 drives the first slider 214 located in the first slide rail 213 to move back and forth. Then, the first slider 214 drives the mounting frame 216 to move via the second rotating shaft 215. During the process, the storage bin 217 outputs sand to the inner tube 219 through the conduit 218. Then, it is transmitted to the outer tube 2112 through the inner tube 219. Finally, it is discharged from the nozzle 2113. Under the drive of the drive cylinder 2111 and the vertical plate 2110, the outer tube 2112 and the nozzle 2113 can extend into the interior of the air intake manifold 200 to perform grinding work.

[0072] It should be noted that there is a damper between the second rotating shaft 215 and the first slider 214 to prevent the sandblasting assembly 21 from changing direction during operation.

[0073] Furthermore, such as Figure 7-13As shown, the sealing assembly 22 includes a sealing plate 221 connected to the outer tube 2112, a ring 223 connected to the sealing plate 221 and connected to the mounting bracket 216 via a second spring 222, a limiting block 224 connected to the nozzle 2113, and a limiting hole 225 opened on the sealing plate 221.

[0074] The directional assembly 23 includes a spiral portion 231, a reset portion 232, and a bending portion 233 that are opened on the outer tube 2112 and are interconnected, a second slide rail 235 that is disposed on the mounting bracket 216 and connected to the second slider 234, and a guide rod 236 that is connected to the second slider 234 and located in the bending portion 233.

[0075] In this embodiment, by setting the directional component 23 and the ventilation component 12 to cooperate with each other, the ventilation component 12 opens the pipe openings of each branch pipe in a targeted manner to guide the abrasive material to perform the grinding work one by one. When the main pipe is being ground, the directional component 23 rotates to fully improve the grinding effect on the inner wall of the main pipe, thereby improving the overall grinding quality of the intake manifold 200.

[0076] In detail, when the outer tube 2112 and nozzle 2113 extend outward under the drive of the drive cylinder 2111, the limiting block 224 on the nozzle 2113 moves along with it, thus releasing the limiting of the sealing plate 221. Then, the sealing plate 221 on the outer tube 2112 extends under the drive of the second spring 222 to seal the main pipe side of the intake manifold 200 to prevent sand from being discharged from the main pipe. At the same time, during the movement of the outer tube 2112, the guide rod 236 connected in the bend 233 moves along with it, thereby driving the second slider 234 to move within the second slide rail 235. At this time, the nozzle 2113 moves from the outside to the inside of the intake manifold 200, and the grinding work begins. When the second slider 234 moves to one side of the second slide rail 235 and stops moving, the guide rod is pushed by the drive cylinder 2111. 236 begins to move in the spiral section 231, causing the outer tube 2112 and nozzle 2113 to begin to rotate. When the nozzle 2113 is reset, the guide rod 236 is located in the reset section 232, and the nozzle 2113 can be fixed in the direction of the branch pipe for reset, thereby performing targeted grinding on the branch pipe. When the nozzle 2113 moves out of the intake manifold 200, it drives the sealing plate 221 to reset through the limiting block 224. At this time, since the guide rod 236 is located in the reset section 232, the direction of the outer tube 2112 has not rotated to the original angle, and therefore the limiting block 224 and the limiting hole 225 are not engaged. When the second slider 234 moves to the other side of the second slide rail 235, the position is fixed. At this time, the outer tube 2112 rotates again by a certain angle under the action of the guide rod 236 and the bending section 233 to complete the reset, and at the same time, the limiting block 224 is engaged in the limiting hole 225.

[0077] It should be noted that when the outer pipe 2112 and nozzle 2113 move forward, due to the spiral movement, multiple sealing columns 122 open the branch pipe openings sequentially from the farthest end, improving the grinding efficiency of the abrasive material in the air intake manifold 200. When the outer pipe 2112 and nozzle 2113 return to their original position, since the nozzle 2113 retracts in a directional manner, multiple sealing columns 122 still open the branch pipe openings sequentially from the farthest end, so that the opened branch pipes correspond to the nozzle 2113. The sealing plate 221 is fitted onto the outer pipe 2112. The ring 223 is designed to avoid hindering the rotation of the subsequent sealing plate 221. A torsion spring plate is provided at the intersection of the spiral part 231 and the reset part 232 to prevent the guide rod 236 from getting stuck in the reset part 232 during the movement of the spiral part 231. Instead, the change should be made at the connection point between the tail end of the spiral part 231 and the reset part 232.

[0078] Furthermore, such as Figure 4 , Figure 7 and Figure 12 As shown, the first rotating assembly 24 includes a half gear 241 connected to the second rotating shaft 215 and two directional racks 242 respectively connected to both sides of the chassis 100 and meshing with the half gear 241 for transmission.

[0079] The second rotating assembly 25 includes a toothed ring 251 connected to the sealing plate 221 and two sets of rotating racks 252 respectively connected to both sides of the chassis 100 and meshing with the toothed ring 251 for transmission.

[0080] In this embodiment, by setting the first rotating component 24, the sandblasting component 21 can automatically complete the turning operation during the back and forth movement, thereby corresponding to the processing work of the two side intake manifolds 200. At the same time, the second rotating component 25 can adjust the flipping of the nozzle 2113, thereby adapting to the structure of the intake manifold 200 main pipe with only one side opening, so that the nozzle 2113 can be aligned with the branch pipe.

[0081] In detail, when the first slider 214 moves to the edge position and begins to change direction, the half gear 241 connected to the second rotating shaft 215 meshes with the reversing gear on the housing 100, causing the sandblasting assembly 21 to complete a 180° turn. At the same time, after the turn, the toothed ring 251 connected to the sealing plate 221 meshes with the flip rack 252, causing the toothed ring 251 to drive the sealing plate 221 to rotate. The sealing plate 221 drives the nozzle 2113 to rotate 180° through the limit block 224.

[0082] It should be noted that a damper is installed between the nozzle 2113 and the outer tube 2112 to ensure the position of the nozzle 2113.

[0083] Furthermore, such as Figure 1-2 and Figure 14-15As shown, the auxiliary mechanism 3 includes a recovery component 31 installed on the casing 100 for timely recovery of sand and a dust removal component 32 installed on the casing 100 for timely collection of fly ash.

[0084] It is worth mentioning that by setting up auxiliary mechanism 3 to collect and process fly ash in a timely manner, the internal environment during the processing can be effectively controlled. At the same time, with the help of recycling component 31, sand can be reused in a timely manner, which helps to reduce the amount of raw materials used.

[0085] In detail, during the polishing process, the dust removal component 32 collects the dust inside the chassis 100, while the recycling component 31 located below collects and reuses the falling sand in a timely manner.

[0086] Example 2

[0087] like Figure 14-15 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0088] Furthermore, such as Figure 14-15 As shown, the recycling assembly 31 includes two rollers 311 connected to the housing 100, a fabric roll 312 connected to the housing 100 and wound around one end of the rollers 311, and a second motor 313 connected to the housing 100 and whose output end is connected to one end of the fabric roll 312.

[0089] The dust removal assembly 32 includes two sets of second drive gears 321 connected to the reciprocating lead screw 211, two sets of second follower gears 323 connected to the housing 100 via a third rotating shaft 322 and meshing with the second drive gears 321, fan blades 324 connected to the third rotating shaft 322, and a dust collector 325 disposed on the top of the housing 100 for dust removal.

[0090] In this embodiment, by setting up the recycling component 31, the sand material falling off the grinding process is discharged, sorted and collected in time and then used in the grinding mechanism 2, thereby saving sand material and reducing the occurrence of excessive sand material accumulation and dust. In addition, the winding method effectively reduces damage to the bottom support object and extends the service life.

[0091] In detail, during the rotation of the reciprocating screw 211, the second drive gear 321 drives the second follower gears 323 on both sides to rotate, which in turn drives the fan blades 324 to rotate through the third rotating shaft 322. At this time, the fan blades 324 located on both sides of the housing 100 guide the dust towards the middle, effectively reducing the occurrence of dust overflowing from both sides. At the same time, the dust collector 325 located in the middle collects and processes the collected dust. During the grinding process, the abrasive falls and is collected above the cloth roll 312. Then, driven by the second motor 313, the cloth roll 312 and the roller 311 rotate to output the cloth, which is collected at the output end of the second motor 313. At this time, the abrasive moves with the cloth roll 312 and is collected and reused from one side of the housing 100.

[0092] Example 3

[0093] like Figure 16 As shown, a forming method of an automatic forming equipment for an impact-resistant engine intake manifold 200 includes the following steps:

[0094] Step 1, main pipe polishing process: First, the intake manifold 200 is placed on the receiving component 11 and enters the housing 100 along the transmission direction. At this time, the sandblasting component 21 is aligned with the main pipe opening of the intake manifold 200 and moves synchronously with the receiving component 11. During the process, the sealing component 22 seals the main pipe opening. The sandblasting component 21 rotates continuously as it moves forward under the action of the directional component 23, thereby fully polishing the inner wall of the main pipe.

[0095] Step 2, the sub-pipe grinding process: when the sandblasting component 21 moves backward, the directional component 23 no longer restricts the direction of the sandblasting component 21. At this time, the sandblasting direction is aligned with the sub-pipe position and moves horizontally backward to grind the sub-pipe. During the whole process, the ventilation component 12 alternately opens multiple sub-pipe outlets, so that the abrasive can be concentrated and moved towards one place, thereby enhancing the grinding effect.

[0096] Step 3, the turning process: After the intake manifold 200 on one side is polished, the sandblasting assembly 21 moves to one side of the chassis 100. Under the combined action of the first rotating assembly 24 and the second rotating assembly 25, the sandblasting direction of the sandblasting assembly 21 is adjusted. Then, the receiving assembly 11 on the other side drives the lower intake manifold 200 to move together with the sandblasting assembly 21 to continue the polishing work.

[0097] Step four, recycling process: During the grinding process, the bottom recycling component 31 quickly discharges the falling sand, and under the action of the dust removal component 32, the dust inside the chassis 100 gathers from both sides to the middle and is discharged outwards for collection.
