Description

Technical Field

[0001] The present invention relates to the technical field of hub processing and production, and specifically relates to a trimming device for an annular plate unit. Background Art

[0002] A hub is the rotating part of the wheel core where the inner contour of the tire is connected to the wheel steel through columns, that is, a metal component installed on the shaft at the center to support the tire. It is also called a wheel rim, steel rim, wheel, or tire bell. Hubs come in a wide variety of types according to diameter, width, forming method, and material.

[0003] Generally, a hub is fixedly connected coaxially by a wheel rim and a wheel spoke. For the wheel rim, its production process generally involves cutting an aluminum plate that meets the size requirements according to the model size of the hub, and then rolling the aluminum plate unit into a circle and welding it. In fact, for this production and processing method, the rolling device, bending device, welding device, and even the rolling device need to be adjusted or customized for different wheel rim blanks corresponding to different current hub models. As a result, after each change in the hub model produced, the production equipment corresponding to the wheel rim blank needs to be adjusted, resulting in a relatively high labor intensity and a reduced production efficiency.

[0004] Moreover, in order to save production costs, hub production enterprises hope that different-sized wheel rims can use as few types of blanks as possible. This can not only shorten the production time and advance the delivery date by stocking up in advance; but also facilitate purchasing raw materials in advance at a lower price according to the price of the raw materials and then carrying out production in advance, thereby further reducing production costs; and it can also avoid the downtime loss of production equipment and ensure the more efficient operation of the inventory and funds of the production enterprise. However, currently, for the production of hubs, it is all small-batch customized production. Since small-batch customized production requires replacing the corresponding equipment molds, after replacing the equipment molds, it will involve debugging and trial production, and mass production can only be carried out after ensuring the product quality. This leads to a relatively fixed and long time cycle for hub production and relatively high production costs; and for the products of small-batch customized production, in order to avoid replenishment during the later transportation process and after-sales process, inventory also has to be reserved for customized products, resulting in relatively high inventory costs; all of the above will further increase the final selling price of the product.

[0005] For this reason, the patent document with the application number 202111230454.4 provides a production process, which realizes the production of wheel rims with different axial widths by using standard parts of large-batch wheel rim blanks, reduces production costs, and effectively combines the large-scale production mode of the enterprise's production end to reduce costs with the small-batch customized production of the sales end.

[0006] However, there is currently no production equipment on the market for quickly trimming an annular plate unit to a blank that meets stamping before the annular plate unit is stamped and formed in the above production process. Summary of the Invention

[0007] The object of the present invention is to overcome the deficiencies of the prior art and provide a trimming device for annular plate units. Through the action of the trimming device for annular plate units, the two ends of the annular plate unit can be trimmed and processed to meet the processing requirements of the rim blank standard in terms of axial length, thereby ensuring the continuous production of multiple subsequent processes for the annular plate unit; through the specific structure of the annular plate tightening device, the annular plate unit can be quickly tightened, fixed, and separated, facilitating the coaxial fixation of the annular plate unit; through the annular plate tightening unit with a petal-like structure, the annular plate tightening unit can be conveniently replaced according to annular plate units of different diameter sizes, thereby improving the applicability; through the annular horizontal plate provided on the vertical sleeve, it is convenient for the annular plate tightening unit to move along the top surface of the annular horizontal plate, and further facilitates the tightening, fixing, and loosening of the annular plate unit; through the action of the horizontal support plate, it is convenient for the annular plate unit to be placed on the horizontal support plate that rises to the top before tightening and after loosening, preventing the annular plate unit from falling under the action of gravity; after the annular plate unit is tightened and fixed, the horizontal support plate moves downward to separate from the annular plate unit, facilitating the processing of the bottom edge of the annular plate unit; through the moving structure of the cutting tool, the annular plate unit of different sizes can be processed.

[0008] The technical solution adopted by the present invention is as follows:

On the top surface of the horizontal base, there is an annular plate tightening device rotatably connected around a vertical axis.

The distance between the side edge of the horizontal support plate facing away from the vertical sleeve and the axis of the vertical sleeve is greater than the outer diameter of the annular plate unit.

[0093] When the standard parts of the rim blank are produced in this application, first, the sheet material is placed along the length direction of the sheet material loading rack 33 of the sheet material sawing device 1. Then, according to the size of the standard parts of the rim blank to be produced, a sheet material limiting device is fixedly connected to the side of the sawing table 30 facing away from the sheet material loading rack 33. The distance between the sheet material limiting device and the saw blade is equal to the circumference of the standard parts of the rim blank to be produced. Then, the sheet material is moved towards the sawing table 30 until it is in limit contact with the sheet material limiting device. Then, the pneumatic piston cylinders 32 on the horizontal crossbars 21 drive the horizontal pressing strips to move downward respectively, so that the horizontal pressing strips press and fix the sheet materials on both sides of the saw blade respectively. Finally, the saw blade is started and moves from one side of the sawing table 30 to the other side along the strip-shaped hole, and then the sheet material unit is sawed off from the sheet material. Then, the saw blade returns to the starting position, and the pneumatic piston cylinder 32 drives the horizontal pressing strip to move upward to the maximum stroke. At this time, the sawed-off sheet material unit is transferred to the next process, and the above actions are repeated for the sheet material to continue cutting the sheet material.

[0094] The cut sheet material can be processed into a structure similar to that processed before welding in step S4 described in the specification and the accompanying drawings of the patent document with the application number 202111230454.4 through the sheet material unit rolling device 5 or the sheet material unit stamping and curling device 3, that is, the sheet material unit is processed into a similar ring structure at the two ends where they are connected, and flanges located in the same plane are provided at both ends of the sheet material unit to facilitate the next welding process.

[0095] When the sheet unit rolling and bending device 5 processes the sheet unit, the lever 40 is moved to one side of the roller driving device 39, and the bearing block D37 is swung upward to be connected to the driving roller 35; then the driven roller A is driven by the roller lifting and adjusting device A to adjust the vertical distance between the driven roller A and the driving roller 35 to be equal to the thickness of the sheet unit, and the driven roller B36 is driven by the roller lifting and adjusting device B to be flush with the driven roller A; then the roller driving device 39 is started, and one end of the sheet unit is placed on the driven roller B36, and the sheet unit is passed under the driving roller 35 in the order of the driven roller B36, the driven roller A, and the other driven roller B36; when a flange needs to be turned out at one end of the sheet unit, the driven roller B36 on the side far from the feeding end of the sheet unit rises under the action of the roller lifting and adjusting device B, so that a flange is formed at the end of the sheet unit passing through the driven roller B36, and the included angle between the flange and the sheet unit is a right angle or an obtuse angle; when the end flange of one end of the sheet unit is completed, then the driven roller B36 moves downward under the action of the roller lifting and adjusting device B, and the sheet unit is rolled and bent; when the other end of the sheet unit passes through the driven roller B36 on the side far from the feeding end of the sheet unit, the corresponding roller lifting and adjusting device B drives the driven roller B36 to rise again, and another flange corresponding to the previous flange is formed at the end of the sheet unit passing through the driven roller B36, and this flange and the previous flange are in the same plane; finally, the bearing block D37 swings to be separated from the driving roller 35, and then the lever 40 pushes out the sheet unit that has completed the rolling and bending process sleeved on the driving roller 35 along the direction of the driving roller 35 from the end corresponding to the bearing block D37.

[0096] When the sheet unit stamping and curling device 3 processes the sheet unit, the steps S1 to S3 described in the specification and the specification drawings of the patent document with the application number 202111230454.4 are adopted to stamp and curl the sheet unit into a formed shape.

[0097] After the sheet metal unit has completed bending and flanging operations, it is welded by the coiled material welding device 4 to form an annular unit plate. The operation of the coiled material welding device 4 when welding the sheet metal unit is as follows: The sheet metal unit that has completed coiling and forming is sleeved on the horizontal fixed plate 61 located outside the base frame 58, and the flanges at both ends of the coiled and formed sheet metal unit are respectively fixed to the horizontal fixed plate 61 after being aligned by the locking clamp blocks 76. At this time, the flanged joint of the sheet metal unit is aligned with the marking groove provided on the horizontal fixed plate 61; then when the lateral moving frame 68 drives the horizontal fixed plate 61 with the sheet metal unit fixed on it to move to the position of the strip-shaped through hole 63, the flanged joint of the sheet metal unit fixed on the horizontal fixed plate 61 is located directly below the walking track of the welding head. Then the scar removal device 60 and the welding device 62 are respectively started, and the milling cutter lifting device and the welding head lifting device respectively drive the milling cutter of the scar removal device 60 and the welding head of the welding device 62 to move downward to correspond to the top surface of the flange of the sheet metal unit fixed to the horizontal fixed plate 61 corresponding to the position of the strip-shaped through hole 63; then the longitudinal driving device A65 drives the scar removal device 60 and the welding device 62 to move towards the sheet metal unit simultaneously, so as to weld the flanged joint of the sheet metal unit and mill the welded scar, so as to ensure that the welded part of the flange is flush with the rest of the flange; at this time, the finished welded annular plate unit is taken and the sheet metal unit to be welded is installed on the horizontal fixed plate 61 located on the other side of the lateral moving frame 68 and outside the base frame 58; when the welding head moves to separate from the flange of the sheet metal unit, the welding head lifting device drives the welding head to move upward to the maximum stroke and stops welding; when the milling cutter moves to separate from the sheet metal unit, the milling cutter lifting device drives the milling cutter to move upward to the maximum stroke and stops rotating; when the longitudinal driving device A65 drives the scar removal device 60 and the welding device 62 to move to the maximum stroke towards one side of the sheet metal unit, the longitudinal driving device A65 then drives the scar removal device 60 and the welding device 62 back to the starting position. At the same time, the lateral moving frame 68 drives the horizontal fixed plate 61 with the finished welded annular plate unit fixed on it to move outside the base frame 58 for taking and installing and fixing another sheet metal unit to be welded, and at the same time drives the horizontal fixed plate 61 with the sheet metal unit to be welded fixed on it to move into the base frame 58 for welding; thus realizing continuous production.

[0098] The circular plate unit after welding is subjected to circular restoration operation through the sheet unit rolling device 5. During the operation, the lever 40 is moved to one side of the roller driving device 39, and the bearing block D37 is swung downward to be separated from the driving roller 35; then the driven roller A is adjusted by the roller lifting and adjusting device A to make the vertical distance between the driven roller A and the driving roller 35 equal to the thickness of the sheet unit, and the driven roller B36 is adjusted by the roller lifting and adjusting device B to be flush with the driven roller A; then the circular plate unit is sleeved on the driving rotating shaft 35 from the end of the driving rotating shaft 35 corresponding to the bearing block D37, and then the bearing block D37 is swung to be connected with the driving roller 35; then the roller driving device 39 is started, and then the driven roller B36 is gradually lifted by the roller lifting and adjusting device B until the circular plate unit is rolled into a cylindrical shape; finally, the roller driving device 39 stops rotating, and the driven roller A and the driven roller B36 are gradually lowered to the starting position by the roller lifting and adjusting device A and the roller lifting and adjusting device B respectively. Then the bearing block D37 is swung to be separated from the driving roller 35, and then the lever 40 pushes out the circular plate unit that has completed the rolling and circular restoration processing and is sleeved on the driving roller 35 along the direction of the driving roller 35 from the end corresponding to the bearing block D37; the operator places the circular plate unit restored by the sheet unit rolling device 5 in the circular plate unit positioning groove on the turntable A.

[0099] When the annular plate unit that has completed the circular restoration process is trimmed by the annular plate unit trimming device 6, first, according to the axial dimension of the annular unit plate and the diameter dimension of the rim blank standard part to be processed, the height position of the tool holder 102 fixedly connected to the tool rest 100 is adjusted, and the height position of the tool rest 100 is adjusted by the lifting drive device C106, so that the distance between the cutting tools 101 conforms to the axial length of the annular plate unit required for the production of the rim blank standard part, and to ensure that the cutting amount of the cutting tools 101 for the annular unit plate is minimized; the translation drive device 105 and the robot A12 clamp the annular plate unit on the turntable A and rotate it to the annular plate unit trimming device 6, and the annular plate unit is sleeved on the annular plate expansion device 82 and then placed on the horizontal support plate 84. At this time, the output shaft 93 and the horizontal support plate 84 rise to the maximum stroke under the action of the lifting drive device A91 and the lifting drive device B97 respectively; then the lifting drive device A91 drives the output shaft 93 to move downward, thereby driving the cone sleeve 88 on the upper part of the output shaft 93 to move downward, and further driving the output shaft contact unit 86 to expand outward under the action of the cone sleeve 88, so that the annular plate expansion unit 85 contacts and expands the annular plate unit to be fixedly connected coaxially; then the lifting drive device B97 drives the horizontal support plate 84 to move downward to the maximum stroke to solidify, and at this time the horizontal support plate 84 is separated from the annular plate unit; then the rotation drive device 83 is started, and the translation drive device 105 drives the lifting seat 104 together with the cutting tools 101 to move towards the annular plate unit, and trims the edges at both ends of the annular plate unit; after the annular plate unit is trimmed, the translation drive device 105 drives the cutting tools 101 to move away from the annular plate unit to the starting position; then the lifting drive device B97 drives the horizontal support plate 84 to move upward to contact the bottom edge of the annular plate unit; then the robot A12 clamps and fixes the annular plate unit still fixed to the annular plate expansion device 82, and then the lifting drive device A91 drives the output shaft 93 to move upward to the maximum stroke, and at this time the cone sleeve 88 on the upper part of the output shaft 93 is separated from the output shaft contact unit 86; finally, the robot A12 takes out the annular plate unit sleeved on the annular plate expansion unit 85 and rotates it;During the turnover process, the camera 119 set by the annular plate unit fixture of the robot A12 observes the quality of the outer circumferential side wall surface of the annular plate unit for one week. When the camera 119 observes that there are defects on the outer circumferential side wall surface of the annular plate unit, the robot A12 turns the annular plate unit to the defective product placement table A24 so that the operator can make a manual judgment on the annular plate unit judged as a defective product.

[0102] When the idle robot D18 detects that there is an annular plate unit in the annular plate unit positioning groove on the turntable D17, the robot D18 transfers the annular plate unit on the turntable D17 to the rim cylinder trimming device 9 to shape the annular plate unit that has completed the flange flanging of the rim, so that the structures of the body part, the flared part, and the rim flanging part of the annular plate unit can be completely coaxial, and ensure that the roundness meets the requirements for subsequent processing; then the robot D18 takes out the annular plate unit that has completed the cylinder shaping process and transfers it. During the transfer process, the camera 119 set on the annular plate unit fixture of the robot D18 observes the quality of the outer circumferential side wall surface of the annular plate unit for one week. If the camera 119 observes that there are defects on the outer circumferential side wall surface of the annular plate unit, the robot D18 transfers the annular plate unit to the defective product placement table D27 so that the operator can make a manual judgment on the annular plate unit judged as a defective product. If the operator judges that the surface defect of the annular plate unit is only oil stain or other impurities, or even a misjudgment by the camera 119, after wiping the surface of the annular plate unit clean and when there is no annular plate unit on the turntable E19, place the annular plate unit in the annular plate unit positioning groove of the turntable E19. If the operator judges that the annular plate unit actually has defects, the operator transfers the defective product to the defective product treatment area for subsequent processing; when the camera 119 of the robot D18 observes that there are no defects on the outer circumferential side wall surface of the annular plate unit, the robot D18 transfers the annular plate unit to the annular plate unit positioning groove of the turntable E19 for normal operation of subsequent processes; then when there is an annular plate unit in the annular plate unit positioning groove on the turntable D17 again, the robot D18 transfers the annular plate unit on the turntable D17 to the rim cylinder trimming device 9 for processing.

[0103] When the idle robot E20 detects a ring plate unit in the ring plate unit positioning groove on the turntable E19, the robot E20 transfers the ring plate unit on the turntable E19 to the rim curling device 10 to perform curling processing on the rim flanging of the ring plate unit that has completed the cylindrical body shaping, so that the flanging of the ring plate unit is curled and fixed to form the rim and flange structure after the second step in step S7 as recorded in the specification and the accompanying drawings of the patent document with the application number 202111230454.4; then the robot E20 takes out the ring plate unit that has completed the rim curling and performs transfer; during the transfer process, the camera 119 provided in the ring plate unit fixture of the robot E20 observes the quality of the outer circumferential side wall surface of the ring plate unit for one week. If there are defects on the outer circumferential side wall surface of the ring plate unit observed by the camera 119, the robot E20 transfers the ring plate unit to the defective product placement table E28 so that the operator can make a manual judgment on the ring plate unit judged as a defective product. If the operator judges that the surface defect of the ring plate unit is only oil stain or other impurities, or even a misjudgment by the camera 119, after wiping the surface of the ring plate unit clean and when there is no ring plate unit on the turntable F21, place the ring plate unit in the ring plate unit positioning groove of the turntable F21. If the operator judges that the ring plate unit indeed has defects, the operator transfers the defective product to the defective product processing area for subsequent processing; when the camera 119 of the robot E20 observes that there are no defects on the outer circumferential side wall surface of the ring plate unit, the robot E20 transfers the ring plate unit into the ring plate unit positioning groove of the turntable F21 for normal operation of subsequent processes; then when there is a ring plate unit in the ring plate unit positioning groove on the turntable E19 again, the robot E20 transfers the ring plate unit on the turntable E19 to the rim curling device 10 for processing.

[0104] When the idle robot F22 detects that there is a ring plate unit in the ring plate unit positioning groove on the turntable F21, the robot F22 transfers the ring plate unit on the turntable F21 to the tire mounting surface shaping device 11, and processes the connection between the body part and the flared part of the ring plate unit that has completed the cylinder shaping to form a tire mounting surface, so that the ring plate unit forms the rim blank standard part structure after the last step in step S7 as recorded in the specification and the accompanying drawings of the patent document with the application number 202111230454.4; then the robot F22 takes out the ring plate unit that has completed the tire mounting surface shaping process and transfers it; during the transfer process, the camera 119 set on the ring plate unit fixture of the robot F22 observes the quality of the outer circumferential side wall surface of the ring plate unit for one week. If there are defects on the outer circumferential side wall surface of the ring plate unit observed by the camera 119, the robot F22 transfers the ring plate unit to the defective product placement table F29 so that the operator can make a manual judgment on the ring plate unit judged as a defective product. If the operator determines that the surface defect of the ring plate unit is only oil stain or other impurities, or even a misjudgment by the camera 119, after wiping the surface of the ring plate unit clean and when there is no ring plate unit on the turntable G23, place the ring plate unit in the ring plate unit positioning groove of the turntable G23. If the operator determines that the ring plate unit actually has defects, the operator transfers the defective product to the defective product treatment area for subsequent processing; when the camera 119 of the robot F22 observes that there are no defects on the outer circumferential side wall surface of the ring plate unit, the robot F22 transfers the ring plate unit into the ring plate unit positioning groove of the turntable G23 to facilitate the normal operation of the subsequent process; then when there is a ring plate unit in the ring plate unit positioning groove on the turntable F21 again, the robot F22 transfers the ring plate unit on the turntable F21 to the tire mounting surface shaping device 11 for processing.

[0105] In the processes involving the above-mentioned robots, when each robot picks up the corresponding annular plate unit, the robot moves to the position of the corresponding annular unit plate according to the image captured by the camera 119, and keeps the annular plate unit fixture perpendicular to the axis of the corresponding annular plate unit, with the symmetric clamping plates 110 located on both sides of the annular plate unit, and the driving roller 111 and the driven roller 112 on the same clamping plate 110 are also symmetrically located on both sides of the axis of the annular plate unit; then the clamping plate driving device 114 drives the clamping plates 110 to move towards each other until the driving roller 111 and the driven roller 112 on the clamping plates 110 are both in contact with and clamp the outer wall of the annular plate unit at the same time; at this time, due to the action of the self-gravity of the annular plate unit, the annular plate unit has a tendency to move downward relative to the roller wheels 127 and roller shafts 126 of the driving roller 111 and the driven roller 112, and because the clamping plate 110 has a clamping force on the annular plate unit, the anti-slip convex rings 151 provided on the surface of the anti-slip cushion layer 141 of the roller shaft 126 are deformed due to the clamping force at the positions corresponding to the contact with the annular plate unit, thereby pressing the annular elastic pieces 152 at the corresponding positions to deform. Since the elastic coefficient of the annular elastic piece 152 is greater than that of the anti-slip convex ring 151, the annular elastic piece 152 exerts a sufficient relative force on the anti-slip convex ring 151 at the corresponding position, thereby providing a force to make the anti-slip convex ring 151 tend to return to its original state, thus ensuring the anti-slip effect of the anti-slip convex ring 151. Moreover, since the anti-slip cushion layer 141 and the cylindrical groove 140 are connected by an annular corrugated structure 144, and the anti-slip cushion layer 141 is provided with an annular flange 145 and a connecting sleeve 146 structure, the friction force generated by the anti-slip cushion layer 141 under the action of the gravity of the annular plate unit is prevented from moving downward relative to the cylindrical groove 140, further ensuring the fixing effect between the clamped annular plate unit and the annular plate unit fixture.

[0106] And it is connected and fixed through the tapered structure of the plug body 129 and the connecting sleeve 146, which further prevents the connecting sleeve 146 from separating from the notch of the cylindrical groove 140.

[0107] And when the camera 119 needs to observe the annular plate unit clamped by the annular plate unit fixture to determine whether it is a defective product, the roller wheel driving device 134 drives the roller wheel 127 to rotate, thereby driving the annular plate unit to rotate, so that the camera 119 can observe the entire outer wall of the annular plate unit.

[0108] The support block 131 of the roller shaft limiting frame 130 is provided with a guiding groove 139 corresponding to the plug body 129, and the guiding groove 139 is matched and limited with the operating convex ring 153 of the plug body 129, so as to play a role in lateral support for the roller shaft 126 and ensure the lateral supporting force of the roller shaft 126.

[0109] Since the pinch roll rotating roll 126 is clamped with the annular plate unit many times for a long time and needs to bear the relative downward movement trend of the annular plate unit, the anti-slip cushion layer 141 needs to be replaced after the pinch roll rotating roll 126 has been used for a long time. When replacing the anti-slip cushion layer 141, only need to screw the plug body 129 until it is separated from the central screw 143 in the cylindrical groove 140, then the anti-slip cushion layer 141 can be replaced. After replacement, screw the plug body 129 and the central screw 143 tightly and fix them again.

[0110] In the process of manufacturing a rim using a rim blank standard part, some rims need to be coaxially welded and fixed with two rim blank standard parts through an annular connecting strip due to special process requirements. The present application can also manufacture and process the connecting strip.

[0111] When it is necessary to manufacture the annular connecting strip, first place the connecting strip raw material along the length direction of the sheet material loading rack 33 of the sheet material sawing device 1, and then fix a sheet material limiting device on the side of the sawing table 30 facing away from the sheet material loading rack 33 according to the size of the rim blank standard part to be manufactured. The distance between the sheet material limiting device and the saw blade is equal to the circumference of the rim blank standard part to be manufactured; then move the connecting strip raw material towards the sawing table 30 until it is in limit contact with the sheet material limiting device; then the pneumatic piston cylinders 32 on the horizontal cross bar 21 drive the horizontal pressing strips to move downward respectively, so that the horizontal pressing strips press and fix the connecting strip raw materials on both sides of the saw blade respectively; finally, the saw blade is started and moves from one side of the sawing table 30 to the other side along the strip-shaped hole, and then the connecting strip unit is sawed off from the connecting strip raw material. Then the saw blade returns to the starting position, and the pneumatic piston cylinder 32 drives the horizontal pressing strip to move upward to the maximum stroke. At this time, the sawed-off connecting strip unit is transferred to the next process, and the above operations are repeated for the connecting strip raw material to continue cutting the connecting strip raw material.

[0112] The cut connecting bar unit is curled into an annular structure by the connecting bar unit curling device 2; during operation, according to the thickness of the connecting bar unit, the distance between the axis connection line of the curling guide pressing wheel A 45 and the curling guide base wheel 44 is adjusted to be equal to the thickness of the connecting bar unit by adjusting the handwheel 52; the distance between the axis connection line of the curling guide pressing wheel B 46 driven by the piston rod 55 when it extends out of the piston cylinder 54 and the curling guide base wheel 44 is adjusted by adjusting the adjusting nut 57 on the adjusting screw rod B 56, and the distance between the axis connection line of the curling guide pressing wheel B 46 driven by the piston rod 55 when it retracts into the piston cylinder 54 and the curling guide base wheel 44 is greater than or equal to the distance between the axis connection line of the curling guide pressing wheel A 45 and the curling guide base wheel 44; the curling guide base wheel 44 is driven by the base wheel driving device, one end of the connecting bar unit is inserted into the space between the curling guide base wheel 44 and the curling guide pressing wheel A 45 from one end far away from the curling guide pressing wheel B 46, and then it is conveyed under the action of the curling guide base wheel 44 until the end of the connecting bar unit passes through the curling guide base wheel 44 corresponding to the curling guide pressing wheel B 46 and contacts the curling guide pressing wheel B 46. When the connecting bar unit passes through the curling guide pressing wheel B 46 for a period of time, the piston cylinder 54 drives the piston rod 55 and the curling guide pressing wheel B 46 to move away from the piston cylinder 54, so as to drive the curling guide pressing wheel B 46 to bend the connecting bar unit around the corresponding curling guide base wheel 44. After being bent, the connecting bar unit extends towards the guide inclined plate 43 after bypassing the curling guide base wheel 44. Due to the action of the guide inclined plate 43, the curled connecting bar unit located on the guide inclined plate 43 will not contact the curling guide base wheel 44, the curling guide pressing wheel A 45 and the curling guide pressing wheel B46, thus not affecting the continuous curling of the connecting bar unit.

[0113] The curled connecting bar unit is welded by the curling material welding device 4 to form an annular connecting bar unit, and the operation method is the same as that of the sheet material unit after bending and flanging is completed and welded by the curling material welding device 4 to form an annular unit sheet.

[0114] The completed welded annular connecting bar unit is then restored to a circular shape by the sheet material unit rolling device 5, and the operation method is the same as the circular restoration operation of the annular unit sheet; the connecting bar unit after the circular restoration operation can be used for the production of the wheel rim.
