Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular, to a manufacturing process for a motorcycle cross-shaped seat. Background Technology

[0002] With the advancement of science and technology, motorcycles have gradually become a common mode of transportation in households, and consumers' requirements for the quality and safety of motorcycles have also gradually increased.

[0003] When a motorcycle is in motion, the uneven road surface often causes the motorcycle to sway, which can loosen the welding points of the power supply box and affect its normal operation. The motorcycle cross-mount, as a connector that secures the power supply box connection points, plays a protective role.

[0004] The cross-shaped base includes a column and four support legs spaced apart around the column. When the cross-shaped base is placed on a flat surface, two of the support legs are in contact with the surface. Figure 8 As shown.

[0005] Due to the special operating environment of the cross-shaped mount, the surface of the mount is required to have good anti-oxidation properties to improve its surface quality. However, given the special shape of the mount, how to meet the above requirements and process the surface of the motorcycle mount with the simplest process has become an important and urgent problem to be solved. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide a manufacturing process for motorcycle cross-shaped bearings, which produces cross-shaped bearings with better surface quality.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0008] A manufacturing process for a motorcycle cross-shaped seat mainly includes the following steps:

[0009] Step 1: Cutting the raw material using a band saw;

[0010] Step 2: Deburring. Use a polishing machine to remove burrs and sharp angles from the surface of the raw material.

[0011] Step 3: Preheating before forging. Place the raw material in a resistance furnace at a temperature of 400-440 degrees Celsius and heat for more than 90 minutes.

[0012] Step 4: Pre-forging. A 630T press is used to perform a second extrusion on the raw material that was initially pre-forged, so that the thickness of the second pre-forged material reaches 28.5-29.7mm.

[0013] Step 5: Preheating before forging. Place the raw material in a resistance furnace at a temperature of 400-440 degrees Celsius and heat for more than 90 minutes.

[0014] Step Six: Final Forging, using a 630T press to extrude the raw material;

[0015] Step 7: Trim the edges. Use a 100T punch press to remove the flash, ensuring the flash allowance is less than 0.6mm.

[0016] Step 8: Solution treatment. Divide the product into 3 layers and place them in a solution furnace at a temperature of 525-535 degrees Celsius for 90 minutes.

[0017] Step 9: Aging treatment. Place the solution-treated product into an aging furnace at an aging temperature of 165-175 degrees Celsius and hold for 480 minutes.

[0018] Step 10: Acid and alkali cleaning. Use alkaline water with a concentration greater than 11 pH to corrode for 30-90 seconds, then rinse with room temperature water. Next, use acid water with a concentration less than 4 pH to corrode for 30-90 seconds, then rinse with room temperature water. Finally, rinse with hot water at a temperature of 60-80 degrees Celsius.

[0019] Step 11: Shot blasting, using a tracked shot blasting machine for tumbling blasting, controlling the shot blasting time to 3 minutes;

[0020] Step 12: Stamping, using a 35T punch press to stamp the lettering on the shot-blasted parts;

[0021] Step Thirteen: Inspection.

[0022] The above technical solution involves using alkaline water to corrode the parts, followed by acid water. The combination of acid and alkaline water effectively removes oxide scale and rust from the parts' surface, preventing residue buildup. Subsequent shot blasting further enhances the smoothness and structural strength of the automotive cross-shaped bearing.

[0023] Preferably, the shot blasting machine used in step eleven uses 304 stainless steel shot with a diameter of 0.3 mm.

[0024] The above technical solution uses 304 stainless steel shot to remove oxide scale and rust from the surface of parts. The diameter of the 304 stainless steel shot is set to 0.3mm to ensure that the surface of the parts is not easily dented when shot blasting.

[0025] Preferably, the machine used for acid and alkali cleaning in step ten is a cleaning machine; the cleaning machine includes a machine body, a feed box is provided on the upper left side of the machine body, a receiving cavity is provided inside the machine body, and an acid and alkali soaking solution is provided at the bottom of the receiving cavity;

[0026] The cavity is equipped with a placement mechanism and a flipping mechanism that move up and down along its height. The placement mechanism is used to place the cross seat, and the flipping mechanism is used to flip the cross seat on the placement mechanism. The body is also equipped with a first driving component, which is used to drive the placement mechanism and the flipping mechanism to slide up and down.

[0027] The feed box is used to place the cross seat and transport the cross seat to the placement mechanism.

[0028] Using the above technical solution, the staff pours the product into the feeding box. The first drive component drives the placement mechanism to the lower side of the feeding box, so that the cross seat in the feeding box falls onto the placement mechanism. Then, the first drive component drives the placement mechanism and the flipping mechanism into the acid and alkali soaking solution, so that the cross seat is flipped by the flipping mechanism while soaking, thereby making the cross seat soaked more evenly.

[0029] Preferably, the first driving component includes a driving source, a first driving rod, a first connecting component, and a second connecting component. The first driving rod is disposed on one side of the body along the height direction of the body. The first connecting component and the second connecting component are respectively slidably disposed on the driving rod. The first connecting component is disposed below the second connecting component. The first connecting component is used to connect the placement mechanism, the second connecting component is used to connect the flipping mechanism, and the driving source is used to drive the first connecting component and the second connecting component to slide up and down.

[0030] The placement mechanism includes a placement platform and a left and right drive assembly. The placement platform is used to place the cross seat, and the left and right drive assembly is used to drive the placement platform to slide left and right.

[0031] The placement platform is located on the lower side of the feeding box. When the feeding box conveys the cross seat, the left and right drive components drive the placement platform to slide to the right.

[0032] The flipping mechanism is located on the right side of the machine body and above the placement platform. When the placement platform slides to the right side of the machine body, the flipping mechanism is used to flip the cross seat.

[0033] With the above technical solution, the initial position of the placement platform is set below the feeding box. When the feeding box conveys the product out and it falls into the placement platform, the placement platform slides to the right side of the machine body under the drive of the left and right drive components, so that the product can fall evenly into the placement platform. Then, when the product is placed on the placement platform, the placement platform slides to the bottom of the flipping mechanism, and then the flipping mechanism flips the product on the placement platform so that the four support legs of the cross seat can be evenly soaked.

[0034] Preferably, the placement platform is provided with a plurality of grooves, the plurality of grooves are used to place the support feet of the cross seat, and a plurality of second drive rods are telescopically arranged in the plurality of grooves. A connecting rod is slidably arranged on one side of the second drive rod to the left and right. When the second drive rod moves downward, it drives the connecting rod to slide to the right.

[0035] A drive switch is also provided on the right side of the placement platform. The drive switch is electrically connected to the flipping mechanism. When several second drive rods move downward, they drive several connecting rods to slide to the right and control the opening and closing of the drive switch.

[0036] Through the above technical solution, the setting of several grooves facilitates the restriction of the placement position of the cross seat, so that two of the four support feet of the cross seat are set in the grooves; when the cross seat is set in the groove, due to the gravity of the cross seat, the drive rod is compressed downward, and the drive connecting rod slides to the right; when all the drive rods are compressed downward, it means that the cross seat has been evenly placed on the placement platform. At this time, several connecting rods and several drive rods work together to make several connecting rods slide to the right to push the drive switch, so that the drive switch controls the flipping mechanism to flip the cross seat on the placement platform.

[0037] Preferably, a discharge port is provided on the right side of the machine body, and a pushing component is provided on the placement platform. The pushing component is used to push the cross seat on the placement platform to the discharge port.

[0038] The feeding assembly includes a first motor, a first lead screw, a first slide bar, and a push plate. The first lead screw and the first slide bar are respectively arranged on both sides of the placement platform along the length direction of the placement platform. The output end of the first motor is connected to the first lead screw. One end of the push plate is threadedly connected to the first lead screw, and the other end of the push plate is slidably connected to the first slide bar.

[0039] With the above technical solution, after the cross seats on the placement platform have been soaked in the acid and alkali soaking solution, the first drive component drives the placement platform to move upward, so that the placement platform is aligned with the discharge port, and then the push component pushes several cross seats on the placement platform out of the discharge port and into the next production process.

[0040] Preferably, the flipping mechanism includes a conveyor belt assembly and a flipping assembly;

[0041] The conveyor belt assembly includes two second motors, two rollers and a conveyor belt. The output ends of the second motors are respectively connected to the two rollers. The conveyor belts are respectively sleeved on the two rollers. The two motors slide up and down and are arranged on the rear side of the machine body.

[0042] The drive switch is electrically connected to the second motor; the flipping assembly is disposed on the conveyor belt and is used to flip the cross seat on the placement platform.

[0043] With the above technical solution, when the conveyor belt rotates in the opposite direction to the movement direction of the placement platform, the flipping component can flip the cross seat on the placement platform.

[0044] Preferably, the flipping assembly includes a plurality of mounting seats, a plurality of connecting shafts, a plurality of springs, and a plurality of flipping plates; the plurality of mounting seats are spaced apart along the periphery of the conveyor belt, and the side of the mounting seat away from the conveyor belt has a mounting groove along the front-back direction of the mounting seat; the connecting shafts are rotatably disposed in the mounting grooves; the springs are sleeved on the connecting shafts; and one end of the flipping plate is connected to the mounting shafts.

[0045] A baffle is formed on the right side of the mounting groove, and a slot is formed on the left side of the mounting groove through the mounting seat. The flip plate can only rotate in the direction of the slot.

[0046] With the above technical solution, when the conveyor belt rotates in the same direction as the placement platform moves, the tilting plate can be adjusted to be a cross seat set in the groove by rotating in the slotted direction after touching the cross seat; when the conveyor belt rotates in the opposite direction to the placement platform moves, the tilting plate is subjected to force on the side of the baffle. At this time, due to the setting of the baffle, the tilting plate can apply force to one of the two support feet of the cross seat facing the conveyor belt side, so that the cross seat is tilted.

[0047] Preferably, the upper side of the feeding box is provided with a feeding port, the lower side of the feeding box is provided with an outlet, a transmission plate is provided at the outlet at a downward angle, and the end of the transmission plate away from the outlet is located at the upper right of the placement platform; the bottom of the feeding box is provided with an adjustment component, which is used to make the cross seat in the feeding box move to the transmission plate in a specified shape.

[0048] With the above technical solution, the staff pours the products directly into the feeding box, and then the adjustment component at the bottom of the feeding box makes the products flow out of the feeding box outlet in the prescribed shape. Then, the products are transported to the placement platform along the inclined conveyor plate. This solves the inconvenience of manually placing products one by one in the traditional way and helps to improve the overall work efficiency. Attached Figure Description

[0058] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0059] A manufacturing process for a motorcycle cross-shaped seat mainly includes the following steps:

[0060] Step 1: Cutting the raw material using a band saw;

[0061] Step 2: Deburring. Use a polishing machine to remove burrs and sharp angles from the surface of the raw material.

[0062] Step 3: Preheating before forging. Place the raw material in a resistance furnace at a temperature of 400-440 degrees Celsius and heat for more than 90 minutes.

[0063] Step 4: Pre-forging. A 630T press is used to perform a second extrusion on the raw material that was initially pre-forged, so that the thickness of the second pre-forged material reaches 28.5-29.7mm.

[0064] Step 5: Preheating before forging. Place the raw material in a resistance furnace at a temperature of 400-440 degrees Celsius and heat for more than 90 minutes.

[0065] Step Six: Final Forging, using a 630T press to extrude the raw material;

[0066] Step 7: Trim the edges. Use a 100T punch press to remove the flash, ensuring the flash allowance is less than 0.6mm.

[0067] Step 8: Solution treatment. Divide the product into 3 layers and place them in a solution furnace at a temperature of 525-535 degrees Celsius for 90 minutes.

[0068] Step 9: Aging treatment. Place the solution-treated product into an aging furnace at an aging temperature of 165-175 degrees Celsius and hold for 480 minutes.

[0069] Step 10: Acid and alkali cleaning. Use alkaline water with a concentration greater than 11 pH to corrode for 30-90 seconds, then rinse with room temperature water. Next, use acid water with a concentration less than 4 pH to corrode for 30-90 seconds, then rinse with room temperature water. Finally, rinse with hot water at a temperature of 60-80 degrees Celsius.

[0070] Step 11: Shot blasting. Use a tracked shot blasting machine for tumbling blasting, set the frequency to 45, and control the shot blasting time to 3 minutes.

[0071] Step 12: Stamping, using a 35T punch press to stamp the lettering on the shot-blasted parts;

[0072] Step Thirteen: Inspection.

[0073] After corroding the parts with alkaline water, acidic water is used for further corrosion. The combination of acid and alkaline water can more thoroughly remove oxide scale and rust from the surface of the parts, making it less likely for oxide scale and rust to remain. After shot blasting, the surface of the automotive cross-shaped seat 5 becomes smoother and has better structural strength. In step eleven, the shot blasting machine uses 304 stainless steel shot with a diameter of 0.3mm. Using 304 stainless steel shot effectively removes oxide scale and rust from the surface of the parts, while the 0.3mm diameter ensures that the surface of the parts is less prone to dents during shot blasting.

[0074] Reference Figure 1 and Figure 2 In step ten, the machine used for acid and alkali cleaning is a cleaning machine. The cleaning machine includes a body 1, a feed box 2 is provided on the upper left side of the body 1, and a receiving cavity 11 is provided inside the body 1. The bottom of the receiving cavity 11 is provided with acid and alkali soaking solution. A placement mechanism 4 and a flipping mechanism 3 are provided in the receiving cavity 11, which move up and down along its height. The placement mechanism 4 is used to place the cross seat 5, and the flipping mechanism 3 is used to flip the cross seat 5 on the placement mechanism 4. A first drive assembly 6 is also provided inside the body 1. The first drive assembly 6 is used to drive the placement mechanism 4 and the flipping mechanism 3 to slide up and down. The feed box 2 is used to place the cross seat 5 and transport the cross seat 5 to the placement mechanism 4. The placement mechanism 4 and the flipping mechanism 3 slide up and down synchronously. The worker pours the product into the feeding box 2. The first drive assembly 6 drives the placement mechanism 4 to the lower side of the feeding box 2, so that the cross seat 5 in the feeding box 2 falls onto the placement mechanism 4. Then, the first drive assembly 6 drives the placement mechanism 4 and the flipping mechanism 3 into the acid and alkali soaking solution, so that the cross seat 5 is flipped by the flipping mechanism 3 while soaking, thus making the cross seat 5 soaked more evenly. This is better than the traditional method of directly placing the cross seat 5 on the tooling grid and then soaking it in the soaking solution, because two of the four support feet 51 of the cross seat 5 will be in contact with the plane, resulting in poor soaking effect of the two support feet 51 in contact during soaking. However, this technical solution uses the flipping mechanism 3 to flip the cross seat 5, so that all four support feet 51 on the cross seat 5 can be soaked evenly.

[0075] Reference Figure 2 , Figure 3 and Figure 4Specifically, the first drive assembly 6 includes a drive source 61, a first drive rod 62, a first connecting assembly 63, and a second connecting assembly 64. The first drive rod 62 is disposed on one side of the body 1 along the height direction of the body 1. The first connecting assembly 63 and the second connecting assembly 64 are respectively slid up and down on the first drive rod 62. The first connecting assembly 63 is disposed below the second connecting assembly 64. The first connecting assembly 63 is used to connect the placement platform 41, and the second connecting assembly 64 is used to connect the flipping mechanism 3. The drive source 61 is used to drive the first connecting assembly 63 and the second connecting assembly 64 to slide up and down. As a preferred embodiment, the drive source 61 is a third motor 611, the first drive rod 62 is a third lead screw 612, the third lead screw 612 is located on the right side of the machine body 1, and a third slide rod 613 is also located on the left side of the machine body 1; the first connecting assembly 63 and the second connecting assembly 64 both include two third nut seats 631 and a support rod 632 connected to the third nut seats 631. The two third nut seats 631 are respectively threaded to the third lead screw 612. The support rod 632 is arranged along the horizontal direction of the machine body 1. One end of the support rod 632 is connected to the third nut seat 631, and the other end of the support rod 632 is slidably connected to the third sliding rod. The third motor 611 is connected to the third lead screw 612. When the third motor 611 rotates, it drives the third lead screw 612 to rotate, and the third lead screw 612 drives the third nut seat 631 to slide up and down along the third lead screw 612. Since the relative positions of the two third nut seats 631 on the first connecting component 63 and the second connecting component 64 remain unchanged and are both on the same third lead screw 612, when the motor rotates, it will drive the first connecting component 63 and the second connecting component 64 to slide up and down along the drive rod 62412 at the same time. That is, the first drive component 6 can drive the placement mechanism 4 and the flipping component 32 to slide up and down at the same time.

[0076] Reference Figure 3 and Figure 4The placement mechanism 4 includes a placement platform 41 and a left and right drive assembly 42. The placement platform 41 is used to place the cross seat 5, and the left and right drive assembly 42 is used to drive the placement platform 41 to slide left and right. The placement platform 41 is located on the lower side of the feed box 2. When the feed box 2 conveys the cross seat 5, the left and right drive assembly 42 drives the placement platform 41 to slide to the right. The flipping mechanism 3 is located on the right side of the machine body 1 and above the placement platform 41. When the placement platform 41 slides to the right side of the machine body 1, the flipping mechanism 3 is used to flip the cross seat 5. The initial position of the placement platform 41 is set below the feed box 2. When the feed box 2 conveys the product out and it falls into the placement platform 41, the placement platform 41 slides to the right side of the machine body 1 under the drive of the left and right drive components 42, so that the product can fall evenly into the placement platform 41. Then, when the product on the placement platform 41 is finished, the placement platform 41 slides to the bottom of the flipping mechanism 3, and then the flipping mechanism 3 flips the product on the placement platform 41 so that the four support feet 51 of the cross seat 5 can be evenly soaked.

[0077] Reference Figure 3 and Figure 4 The left and right drive assembly 42 includes a fourth motor 421, a fourth lead screw 422, a fourth slide rod, and several fourth nut seats 423. The fourth lead screw 422 and the fourth slide rod are each a support rod 632 of the first connecting assembly 63. The fourth lead screw 422 is rotatably connected to the third nut seat 631, and the fourth slide rod is connected to the third nut seat 631. The output end of the fourth motor 421 is connected to the fourth lead screw 422, and the fourth nut seat 423 is fixedly connected to the lower side of the placement platform 41. When the fourth motor 421 rotates, it drives the fourth lead screw 422 to rotate. The fourth lead screw 422 drives the fourth nut seat 423, which is threaded to it, to slide along its length, thus driving the placement platform 41 to slide left and right. Therefore, the first drive assembly 6 drives the placement platform 41 to slide up and down, and then the left and right drive assembly 42 drives the placement platform 41 to slide left and right.

[0078] Reference Figure 4 and Figure 5To ensure that the cross base 5 can be placed more orderly on the placement platform 41, the placement platform 41 is provided with several grooves 411 for placing the support feet 51 of the cross base 5. Several second drive rods 412 are telescopically arranged in the grooves 411. A connecting rod 413 is slidably arranged on one side of the second drive rod 412. When the second drive rod 412 moves downward, it drives the connecting rod 413 to slide to the right. A drive switch is also provided on the right side of the placement platform 41. The drive switch is electrically connected to the flipping mechanism 3. When all the second drive rods 412 move downward, it drives all the connecting rods 413 to slide to the right and controls the opening and closing of the drive switch. The arrangement of several grooves 411 facilitates the restriction of the placement position of the cross seat 5, allowing two of the four support legs 51 of the cross seat 5 to be placed within the grooves 411. When the cross seat 5 is placed within the grooves 411, the weight of the cross seat 5 causes the second drive rod 412 to compress downwards, driving the connecting rod 413 to slide to the right. When all the second drive rods 412 are compressed downwards, it means that the cross seat 5 has been evenly placed on the placement platform 41. At this time, the several connecting rods 413 and the several second drive rods 412 work together to cause the several connecting rods 413 to slide to the right, pushing the drive switch, which in turn controls the flipping mechanism 3 to flip the cross seat 5 on the placement platform 41.

[0079] Reference Figure 5 Specifically, an arc-shaped piece 414 is provided on the side of the second drive rod 412 facing the groove 411. The side of the second drive rod 412 away from the groove 411 is connected to one end of the spring 323, and the other end of the spring 323 is connected to the bottom of the groove 411. The spring 323 is sleeved on the second drive rod 412, and a wedge-shaped rod 415 is provided perpendicularly to the end of the second drive rod 412 near the arc-shaped piece 414. Both ends of the wedge-shaped rod 415 are wedge-shaped. A sliding table 416 is also provided on the placement platform 41 below the wedge-shaped rod 415 along the direction of the wedge-shaped rod 415. The spring 323 is provided inside the sliding table 416. One end of the spring 323 is connected to the ground of the sliding table 416, and the other end of the sliding table 416 is connected to the connecting rod 413. When the cross seat 5 is placed in the groove 411, the two support feet 51 of the cross seat 5 will contact the arc plate 414, and then the second drive rod 412 will be compressed downward, causing the wedge rod 415 to move downward. During the downward movement of the wedge rod 415, the connecting rod 413 will be driven to move in the direction of the drive switch. When all the grooves 411 are equipped with cross seats 5, several connecting rods 413 and wedge rods 415 work together to trigger the drive switch, causing the flipping mechanism 3 to flip the cross seats 5 on the platform 41.

[0080] Reference Figure 1 and Figure 4The machine body 1 has a discharge port 12 on its right side, and a pushing assembly 7 is provided on the placement platform 41. The pushing assembly 7 is used to push the cross seats 5 on the placement platform 41 to the discharge port 12. The pushing assembly 7 includes a first motor 71, a first lead screw 72, a first slide rod 73, and a push plate 74. The first lead screw 72 and the first slide rod 73 are respectively arranged on both sides of the placement platform 41 along the length direction of the placement platform 41. The output end of the first motor 71 is connected to the first lead screw 72. One end of the push plate 74 is threadedly connected to the first lead screw 72, and the other end of the push plate 74 is slidably connected to the first slide rod 73. After the cross seats 5 on the placement platform 41 have been soaked in the acid and alkali soaking solution, the first drive assembly 6 drives the placement platform 41 to move upward, so that the placement platform 41 is aligned with the discharge port 12. Then, the pushing assembly 7 pushes several cross seats 5 on the placement platform 41 out of the discharge port 12 and into the next production process.

[0081] Reference Figure 2 , Figure 3 and Figure 7 The flipping mechanism 3 includes a conveyor belt assembly 31 and a flipping assembly 32. The conveyor belt assembly 31 includes two second motors 311, two rollers 312, and a conveyor belt 313. The output ends of the two motors are respectively connected to the two rollers 312, and the conveyor belt 313 is respectively fitted onto the two rollers 312. The two motors slide up and down and are located on the rear side of the machine body 1. A drive switch is electrically connected to the second motors 311. The flipping assembly 32 is disposed on the conveyor belt 313 and is used to flip the cross seat 5 on the placement platform 41. When the rotation direction of the conveyor belt 313 is opposite to the movement direction of the placement platform 41, the flipping assembly 32 can flip the cross seat 5 on the placement platform 41. The flipping assembly 32 includes several mounting seats 321, several connecting shafts 322, several springs 323, and several flipping plates 324. The mounting seats 321 are spaced apart along the periphery of the conveyor belt 313. The side of the mounting seat 321 away from the conveyor belt 313 has a mounting groove in the front-back direction of the mounting seat 321. The connecting shafts 322 are rotatably mounted in the mounting groove. The springs 323 are sleeved on the connecting shafts 322. One end of the flipping plate 324 is connected to the mounting shaft. A baffle is vertically provided on the right side of the mounting seat 321. A slot is opened through the mounting groove on the left side of the mounting seat 321. The flipping plate 324 can only rotate in the direction of the slot. When the conveyor belt 313 rotates in the same direction as the placement platform 41, the tilting plate 324 rotates in the slotted direction after touching the cross seat 5, which can be adjusted to be the cross seat 5 set in the groove 411; when the conveyor belt 313 rotates in the opposite direction to the placement platform 41, the tilting plate 324 is subjected to force on the side of the baffle. At this time, due to the setting of the baffle, the tilting plate 324 can apply force to one of the two support feet 51 of the cross seat 5 facing the side of the conveyor belt 313, so that the cross seat 5 is tilted.

[0082] Reference Figure 1 and Figure 2 The feeding box 2 has an inlet 21 on its upper side and an outlet 22 on its lower side. A conveyor plate 23 is inclined downwards at the outlet 22, with one end of the conveyor plate 23 away from the outlet 22 positioned at the upper right of the placement platform 41. An adjustment component 8 is located at the bottom of the feeding box 2. This component is used to guide the cross-shaped seats 5 inside the feeding box 2 to the conveyor plate 23 in a predetermined shape. The adjustment component 8 can be a vibratory feeder or other device, as long as it can ensure that the cross-shaped seats 5 are discharged from the outlet 22 in a uniform shape. Workers pour the products directly into the feeding box 2, and then the adjustment component 8 at the bottom of the feeding box 2 guides the products to flow out of the outlet 22 in a predetermined shape. The products are then conveyed along the inclined conveyor plate 23 to the placement platform 41. This solves the inconvenience of manually placing products one by one, thus improving overall work efficiency.

[0083] The specific implementation steps of this technical solution are as follows:

[0084] The worker pours the cross seat 5 into the feed box 2. The adjustment component 8 at the bottom of the feed box 2 discharges the cross seat 5 from the outlet 22 of the feed box 2 into a certain shape onto the inclined transmission plate 23. At this time, the right end of the placement platform 41 is located below the side of the transmission plate 23 away from the outlet 22. When the cross seat 5 comes down from the transmission plate 23, the placement platform 41 slowly slides to the right under the left and right drive components 42, so that the cross seat 5 is evenly distributed on the placement platform 41. Since the placement platform 41 has several grooves 411, when the cross seat 5 falls into the placement platform 41, the two supporting feet 51 of the cross seat 5 may not necessarily enter the grooves 411. Therefore, at this time, the rotation direction of the conveyor belt 313 will be consistent with the movement direction of the placement platform 41, so that the tilting plate 324 on the conveyor belt 313 adjusts the cross seat 5 that has not entered the groove 411, so that the cross seat 5 enters the groove 411. Then, since the tilting plate 324 can rotate in the slotting direction at this time, the force applied by the tilting plate 324 to the cross seat 5 is small, and it can only make the cross seat 5 enter the groove 411.

[0085] When the cross seat 5 is fully inserted into the groove 411, the second drive rod 412 will drive the wedge rod 415 to move downwards. The wedge rod 415 will then drive the connecting rod 413 to slide to the right. With the cooperation of several connecting rods 413 and the wedge rod 415, the drive switch is pressed, causing the drive switch to control the second motor 311 to reverse, thereby driving the conveyor belt 313 to reverse, causing the tilting plate 324 to reverse the cross seat 5. At this time, both the tilting mechanism 3 and the placement mechanism 4 slide downwards and are immersed in the acid / alkali soaking solution under the drive of the first drive assembly 6.

[0086] After the cross seat 5 has been soaked in the acid and alkali soaking solution, the first drive component 6 drives the flipping mechanism 3 and the placement mechanism 4 to move upward, so that the placement platform 41 corresponds to the discharge port 12 of the machine body 1. Then, the pushing component 7 pushes the cross seat 5 on the placement platform 41 to the discharge port 12 and enters the next process.

[0087] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
