Description

Technical Field

[0001] This invention relates to the field of wheel rim processing technology, specifically a spinning method for processing forward and reverse wheel rims and hubs. Background Technology

[0002] The wheel rim, also known as the wheel hub, is the component around which the tire is mounted. The wheel rim structure is an important part of the automobile wheel, serving as the basis for tire assembly and fixation. Most wheel rims are welded steel structures, composed of multiple parts and assembled through multiple processes, making installation complex. They are mostly made of steel and are heavy.

[0003] When assembling the wheel rims and hubs with the blanks, welding is mostly used. During the welding process, defects such as welding deformation and welding cracks may occur. These defects will affect the strength and safety of the rim. Spinning is also used, but the spinning head is fixed and the distance cannot be changed, resulting in uneven spinning thickness. Summary of the Invention

[0004] The purpose of this invention is to provide a spinning method for machining forward and reverse wheel rims and hubs. By having a sliding seat slide vertically on a sliding frame, the side plate and high-pressure wheel move from top to bottom. During the downward sliding process, the two sliding frames move away from each other, so that the rim part of the forward and reverse wheel rim and hub is spun from top to bottom along the outer surface of the preheated blank to form the spun workpiece. Through the cooperation of the two sliding frames moving away from or close to each other and the up and down sliding of the sliding seat, uniform spinning is achieved with a high degree of automation, thus solving the problems mentioned in the background art.

[0005] This invention can be achieved through the following technical solution: a spinning method for machining rims and hubs in both forward and reverse directions, the spinning method comprising the following steps:

[0006] Step 1: Place the preheated blank into the top of the high-speed rotating disk. The two-way cylinder pushes the two push blocks to contact the inner wall of the preheated blank, thus indirectly fixing the preheated blank to the high-speed rotating disk. Then, attach the forward and reverse wheel rims to the top of the preheated blank.

[0007] Step 2: The heating head preheats the rim of the forward and reverse rim hub. The two sliding frames slide closer or further apart, while the sliding seat slides on the sliding frame, causing the corresponding high-pressure wheelset to reciprocate and press the forward and reverse rim hub with the preheated blank.

[0008] Step 3: After spinning is completed, the electric push rod pushes the fixing plate and the chuck assembly to descend. The two clamping blocks in the chuck assembly clamp the spun workpiece and move the workpiece out by sliding the sliding sleeve on the linear guide rail.

[0009] A further technical improvement of the present invention is that: in step one, the first cylinder pushes the three-sided cover downward to cover the outside of the high-speed rotating disk and the side plate, and the second cylinder pushes the pressure plate to connect the forward and reverse wheel rims and hubs with the preheated blank.

[0010] A further technical improvement of the present invention is that, in step one, the high-speed rotation of the high-speed rotating disk simultaneously drives the preheated blank and the forward and reverse wheel rims and hubs to move together.

[0011] A further technical improvement of the present invention is that: in step two, one of the limiting plates is pushed back and forth by the electric push rod to slide against the slide rod, and the corresponding linkage rod is rotated by the slide rod. The linkage rod drives the connecting arm to deflect the swinging component, thereby realizing that the limiting plates move away from or closer to each other.

[0012] A further technical improvement of the present invention is that: in step two, when the two limiting plates move away from or close to each other, the sliding seat and the side plate are pushed by the synchronous cylinder to move up and down repeatedly, and the rim of the forward and reverse rim hub is spun from top to bottom after being preheated by the high-pressure wheelset.

[0013] A further technical improvement of the present invention is that: in step three, the three-sided cover is lifted and opened, the sliding sleeve slides to the top of the forward and reverse rim hub, and the two clamping blocks are driven by the clamping cylinder to clamp each other, thereby clamping and fixing the spun workpiece.

[0014] A further technical improvement of the present invention is that: in step three, the fixed plate is then raised by an electric push rod and slides along the linear guide rail to the top of the conveyor belt, transferring the spun workpiece onto the conveyor belt.

[0015] The present invention also provides a spinning device for processing forward and reverse wheel rims and hubs, comprising an L-shaped spinning frame, a high-speed rotating disk rotatably mounted on the top surface of the spinning frame, a preheating blank mounted on the top surface of the high-speed rotating disk and rotating synchronously with the high-speed rotating disk, a forward and reverse wheel rim and hub sleeved on the top of the preheating blank, two sliding frames sliding horizontally arranged on the inner wall surface of the L-shaped end of the spinning frame, and a heating head for preheating the rim portion of the forward and reverse wheel rim and hub mounted on the inner wall surface of the L-shaped end of the spinning frame, a sliding seat sliding vertically arranged on the inner wall surface of each sliding frame, and the two sliding frames being close to or far from each other, a side plate fixedly connected to the outer surface of the sliding seat, and a high-pressure wheel for reciprocating spinning the rim portion of the forward and reverse wheel rim and hub mounted on the inner wall surface of the side plate via a bracket;

[0016] The surface of the L-shaped end of the spinning frame is provided with two limiting cavities, and a fixed seat is fixedly connected to the outer wall of the L-shaped end of the spinning frame between the two limiting cavities. A swinging component is rotatably installed on the middle surface of the fixed seat. The middle part of the swinging component is set as a circular block. Connecting arms are symmetrically arranged on the outer surface of the circular block. A linkage rod is hinged to the end of each connecting arm. A limiting plate is hinged to the end of each linkage rod. There are two limiting plates, which slide in the corresponding limiting cavities, and the limiting plates are fixedly connected to the sliding frame.

[0017] Both limiting cavities are fixedly connected to the middle of a sliding rod that slides with the limiting plate. An electric push rod is installed on the inner wall of one of the limiting cavities. The pushing end of the electric push rod is fixed to the side of the limiting plate. The linkage rod is rotatably arranged between the limiting plate and the connecting arm of the swing member.

[0018] Each of the sliding frames is equipped with a synchronous cylinder on its top surface for pushing the sliding seat to move vertically, and the surface of the sliding frame is provided with a sliding groove for sliding engagement with the sliding seat.

[0019] Below the top horizontal plate of the spinning frame, a three-sided cover is installed, which is pushed by a first cylinder and used for protection. Above the inner cavity of the three-sided cover, a pressure plate is installed, which is pushed by a second cylinder and used to press the forward and reverse wheel rims and hubs.

[0020] A horizontally placed linear guide rail is installed on the upper surface of the L-shaped end of the spinning frame. A sliding sleeve is slidably sleeved on the outside of the linear guide rail. A conveyor belt for conveying the spun workpiece is provided on the surface of the spinning frame and near the end of the sliding sleeve. An electric push rod is installed on the bottom surface of the sliding sleeve. A fixing plate is fixed to the telescopic end of the electric push rod. A jaw assembly for clamping the spun workpiece is installed on the bottom surface of the fixing plate. The jaw assembly includes two clamping blocks that contact the outer surface of the spun workpiece.

[0021] A clamping cylinder is installed on the bottom surface of the fixing plate. Both drive ends of the clamping cylinder are connected to support blocks. The end of each support block is fixedly connected to the inner wall surface of the corresponding clamping block.

[0022] A bidirectional cylinder is installed in the middle of the top surface of the high-speed rotating disk, and each of the two pushing ends of the bidirectional cylinder is equipped with a pushing block that abuts against the inner wall of the preheated blank.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The sliding seat slides vertically on the sliding frame, driving the side plate and high-pressure wheel to move from top to bottom. During the sliding process from top to bottom, the two sliding frames move away from each other, so that the rim of the positive and negative wheel hubs is spun from top to bottom along the outer surface of the preheated blank to form the spun workpiece. Through the cooperation of the two sliding frames moving away from or close to each other and the up and down sliding of the sliding seat, uniform spinning work is achieved with a high degree of automation.

[0025] 2. The first cylinder pushes the three-sided cover downward to cover the outside of the high-speed rotating disk and the two side plates. At the same time, the second cylinder pushes the pressure plate downward. The pressure plate presses down to completely cover the rim of the forward and reverse wheel hubs, making it easier to spin the blank.

[0026] 3. The sliding sleeve slides to the top of the forward and reverse wheel hubs, and drives two support blocks through the clamping cylinder. The support blocks drive the corresponding clamping blocks to clamp each other, clamping and fixing the spun workpiece. Then, the electric push rod lifts the fixing plate and slides it along the linear guide rail to the top of the conveyor belt. Then, the electric push rod extends and moves the spun workpiece to the upper surface of the conveyor belt. Then, the clamping cylinder works to open the two clamping blocks. At this time, the spun workpiece is transferred to the conveyor belt, making it convenient to transport the spun workpiece to the next processing step. Attached Figure Description

[0034] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0035] Please see Figures 1-5 As shown, the present invention provides a spinning device for processing forward and reverse wheel rims and hubs, including an L-shaped spinning frame 1. A high-speed rotating disk 4 is rotatably mounted on the top surface of the spinning frame 1. A preheating blank 9, which rotates synchronously with the high-speed rotating disk 4, is mounted on the top surface of the high-speed rotating disk 4. A forward and reverse wheel rim and hub 10 is sleeved on the top of the preheating blank 9. Two sliding frames 7 that slide horizontally are provided on the inner wall of the L-shaped end of the spinning frame 1, and a heating head 8 for preheating the rim of the forward and reverse wheel rim and hub 10 is installed on the inner wall of the L-shaped end of the spinning frame 1. A sliding seat 20 that slides vertically is provided on the inner wall of each sliding frame 7, and the two sliding frames 7 are close to or far from each other. A side plate 21 is fixed to the outer surface of the sliding seat 20. A high-pressure wheel 22 for reciprocating spinning of the rim of the forward and reverse wheel rim and hub 10 is mounted on the inner wall of the side plate 21 through a bracket. First, the preheating blank 9 is mounted on the upper surface of the high-speed rotating disk 4. Then, the forward and reverse rim hub 10 is fitted onto the upper part of the preheated blank 9. Then, the first cylinder pushes the three-sided cover 11 downward and into contact with the surface of the spinning frame 1, thereby spinning and protecting the forward and reverse rim hub 10 and the preheated blank 9. Then, the heating head 8 is used to preheat the rim part of the forward and reverse rim hub 10. At the same time, the two sliding frames 7 move closer or further away from each other, driving the side plate 21 and the high pressure wheel 22 to spin the rim part of the forward and reverse rim hub 10. In this process, the sliding seat 20 slides vertically on the sliding frame 7, driving the side plate 21 and the high pressure wheel 22 to move from top to bottom. During the sliding from top to bottom, the two sliding frames 7 move further away from each other, so that the rim part of the forward and reverse rim hub 10 is spun from top to bottom along the outer surface of the preheated blank 9 to form the spun workpiece. In the spinning process, the spinning work is realized through the cooperation of the two sliding frames 7 moving further or further away from each other and the up and down sliding of the sliding seat 20. The degree of automation is high.

[0036] Two limiting cavities 23 are provided on the surface of the L-shaped end of the spinning frame 1, and a fixed seat 27 is fixedly connected to the outer wall of the L-shaped end of the spinning frame 1 between the two limiting cavities 23. A swinging member 28 is rotatably mounted on the middle surface of the fixed seat 27. The middle part of the swinging member 28 is set as a circular block. Connecting arms are symmetrically arranged on the outer surface of the circular block. A linkage rod 29 is hinged to the end of each connecting arm. A limiting plate 26 is hinged to the end of each linkage rod 29. There are two limiting plates 26, which slide in the corresponding limiting cavities 23. The limiting plates 26 are fixedly connected to the sliding frame 7. A sliding rod 25 that slides with the limiting plate 26 is fixedly connected to the middle of each of the two limiting cavities 23. An electric push rod 24 is installed on the inner wall of one of the limiting cavities 23. The pushing end of the electric push rod 24 is fixed to the side of the limiting plate 26. The linkage rod 29 is rotatably set between the limiting plate 26 and the connecting arm of the swing member 28. When the rim of the wheel hub 10 is spun, the two sliding frames 7 first move away from each other. The pushing end of the electric push rod 24 pushes one of the limiting plates 26 and the sliding rod 25 to slide in a limited position. The sliding rod 25 drives the corresponding linkage rod 29 to rotate. The linkage rod 29 is hinged to the connecting arm. The connecting arm causes the swing member 28 to deflect. The other connecting arm of the swing member 28 is pulled, thereby making the limiting plate 26 and the sliding frame 7 move away from each other. During the retraction process, the electric push rod 24 makes the two limiting plates 26 and the sliding frame 7 move closer to each other.

[0037] Each sliding frame 7 is equipped with a synchronous cylinder 19 on its top surface to push the sliding seat 20 to move vertically. The surface of the sliding frame 7 is provided with a sliding groove 18 for sliding engagement of the sliding seat 20. The synchronous cylinder 19 synchronously pushes the two sliding seats 20 to slide within the sliding groove 18. At this time, the two high-pressure wheels 22 rise or fall synchronously to ensure the quality and effect of spinning.

[0038] Below the top horizontal plate of the spinning frame 1, a three-sided cover 11 is installed, which is pushed by a first cylinder and used for protection. Above the inner cavity of the three-sided cover 11, a pressure plate 12 is installed, which is pushed by a second cylinder and used to press the forward and reverse rim hub 10. When the rim part of the forward and reverse rim hub 10 is inserted into the top of the preheated blank 9, the three-sided cover 11 is pushed downward by the first cylinder to cover the outside of the high-speed rotating disk 4 and the two side plates 21. At the same time, the pressure plate 12 is pushed downward by the second cylinder. The pressure plate 12 presses down to completely cover the rim part of the forward and reverse rim hub 10 to cover the outside of the preheated blank 9, which facilitates the spinning operation.

[0039] A horizontally placed linear guide rail 2 is mounted on the upper surface of the L-shaped end of the spinning frame 1. A sliding sleeve 3 is slidably sleeved on the outside of the linear guide rail 2. A conveyor belt 30 for conveying the spun workpiece is provided on the surface of the spinning frame 1 and near the end of the sliding sleeve 3. An electric push rod 13 is mounted on the bottom surface of the sliding sleeve 3. A fixing plate 14 is fixedly connected to the telescopic end of the electric push rod 13. A jaw assembly for clamping the spun workpiece is mounted on the bottom surface of the fixing plate 14. The jaw assembly includes two clamping blocks 17 that contact the outer surface of the spun workpiece. A clamping cylinder 15 is mounted on the bottom surface of the fixing plate 14. Each of the two drive ends of the clamping cylinder 15 is connected to a support block 16. The end of each support block 16 is connected to the inner end of the corresponding clamping block 17. After the workpiece is spun, the three-sided cover 11 is lifted and opened, and the sliding sleeve 3 slides to the top of the forward and reverse rim hub 10. The clamping cylinder 15 drives the two support blocks 16, which in turn drive the corresponding clamping blocks 17 to clamp each other, thus clamping and fixing the spun workpiece. Then, the electric push rod 13 lifts the fixing plate 14 and slides it along the linear guide rail 2 to the top of the conveyor belt 30. The electric push rod 13 then extends and moves the spun workpiece to the upper surface of the conveyor belt 30. The clamping cylinder 15 then opens the two clamping blocks 17, and the spun workpiece is transferred to the conveyor belt 30 for easy transport to the next processing step.

[0040] A double-acting cylinder 5 is installed in the middle of the top surface of the high-speed rotating disk 4. Both pushing ends of the double-acting cylinder 5 are equipped with push blocks 6 that abut against the inner wall surface of the preheated blank 9. When the preheated blank 9 is installed on the upper surface of the high-speed rotating disk 4, the double-acting cylinder 5 pushes the push blocks 6 at both ends to abut against the inner wall surface of the preheated blank 9, thereby fixing the preheated blank 9 to the high-speed rotating disk 4 and achieving high-speed rotation.

[0041] The present invention also provides a spinning method for machining rims and hubs in both forward and reverse directions, the spinning method comprising the following steps:

[0042] Step 1: Insert the preheated blank 9 into the top of the high-speed rotating disk 4. The two-way cylinder 5 pushes the two push blocks 6 to contact the inner wall of the preheated blank 9, thus indirectly fixing the preheated blank 9 to the high-speed rotating disk 4. Then, the forward and reverse wheel rim hub 10 is fitted onto the top of the preheated blank 9.

[0043] Step 2: The heating head 8 preheats the rim of the forward and reverse rim hub 10. The two sliding frames 7 slide closer or further apart, while the sliding seat 20 slides on the sliding frame 7, which drives the corresponding high pressure wheel 22 to reciprocate and press the forward and reverse rim hub 10 and the preheated blank 9.

[0044] Step 3: After spinning is completed, the electric push rod 13 pushes the fixed plate 14 and the chuck assembly to descend. The two clamping blocks 17 in the chuck assembly clamp the spun workpiece and move the workpiece out by sliding the sliding sleeve 3 on the linear guide rail 2.

[0045] In step one, the first cylinder pushes the three-sided cover 11 downward to cover the outside of the high-speed rotating disk 4 and the two side plates 21, and the second cylinder pushes the pressure plate 12 to connect the forward and reverse wheel rim hub 10 with the preheated blank 9.

[0046] In step one, the high-speed rotation of the high-speed rotating disk 4 simultaneously drives the preheated blank 9 and the forward and reverse rim hub 10 to move together.

[0047] In step two, the electric push rod 24 reciprocates to push one of the limiting plates 26 and slide rod 25 to slide in a limited position. The slide rod 25 drives the corresponding linkage rod 29 to rotate. The linkage rod 29 drives the connecting arm to deflect the swing member 28, thereby realizing the mutual movement of the limiting plates 26.

[0048] In step two, when the two limiting plates 26 move away from or close to each other, the synchronous cylinder 19 pushes the sliding seat 20 and the side plate 21 to move up and down repeatedly, and the high-pressure wheel 22 spins the rim of the preheated forward and reverse rim hub 10 from top to bottom.

[0049] In step three, the three-sided cover 11 is lifted and opened, the sliding sleeve 3 slides to the top of the forward and reverse rim hub 10, and the two clamping blocks 17 are driven by the clamping cylinder 15 to clamp each other and fix the spun workpiece.

[0050] In step three, the electric push rod 13 then raises the fixed plate 14 to a height and slides it along the sliding sleeve 3 on the linear guide rail 2 to the top of the conveyor belt 30, transferring the spun workpiece onto the conveyor belt 30.

[0051] When in use, the sliding seat 20 slides vertically on the sliding frame 7, driving the side plate 21 and the high-pressure wheel 22 to move from top to bottom. During the sliding process from top to bottom, the two sliding frames 7 move away from each other, so that the rim part of the forward and reverse rim hub 10 is spun from top to bottom along the outer surface of the preheated blank 9 to form the spun workpiece. Through the cooperation of the two sliding frames 7 moving away from or close to each other and the up and down sliding of the sliding seat 20, uniform spun work is achieved with a high degree of automation.

[0052] The first cylinder pushes the three-sided cover 11 downward to cover the outside of the high-speed rotating disk 4 and the two side plates 21. At the same time, the second cylinder pushes the pressure plate 12 downward. The pressure plate 12 presses down to completely cover the rim of the forward and reverse rim hub 10 to cover the outside of the preheated blank 9, which facilitates the spinning operation.

[0053] The sliding sleeve 3 slides to the top of the forward and reverse rim hub 10, and drives the two support blocks 16 through the clamping cylinder 15. The support blocks 16 drive the corresponding clamping blocks 17 to clamp each other, clamping and fixing the spun workpiece. Then, the electric push rod 13 lifts the fixing plate 14 and slides it on the linear guide rail 2 to the top of the conveyor belt 30. Then, the electric push rod 13 extends and moves the spun workpiece to the upper surface of the conveyor belt 30. Then, the clamping cylinder 15 works to open the two clamping blocks 17. At this time, the spun workpiece is transferred to the conveyor belt 30, which facilitates the transportation of the spun workpiece to the next processing step.
