[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0050] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The directional terms used in this invention, such as upper, lower, front, back, left, right, inner, outer, upper surface, lower surface, side, top surface, bottom, front end, rear end, and end, are merely directions in the accompanying drawings and are used only to explain and illustrate this invention, not to limit the scope of protection of this invention.

[0051] In the accompanying drawings, components with identical structures are indicated by the same numerical designation. When some components are described as being "on" another component, the component may be directly placed on the other component; alternatively, an intermediate component may exist, on which the component is placed, and the intermediate component is placed on the other component. When a component is described as being "mounted to" or "connected to" another component, both can be understood as being directly "mounted" or "connected," or as one component being indirectly "mounted to" or "connected to" another component via an intermediate component.

[0052] As described in the background section, steel rims are components used in automotive air suspensions. During production, thin steel sheets are bent, their ends welded together, and the weld seam is ground smooth. However, steel rims produced using this method generally suffer from poor roundness, requiring further shaping to improve their roundness. However, existing technologies lack shaping devices for these welded steel rims.

[0053] To address this technical problem, the inventor has developed a shaping device suitable for welding iron rings. The shaping mold has a simple structure, and the welding iron ring can be shaped by pressing down from above using a hydraulic component, which greatly improves the roundness of the welding iron ring. Furthermore, the shaping process is very simple, which greatly improves the production efficiency of iron rings.

[0054] Please see Figure 2The shaping device for welded iron rings according to one embodiment of the present invention includes a machine base 200 and a hydraulic assembly 300, a mold assembly 400, a feeding assembly 600, a discharging assembly 700, and a clamping and transferring assembly 900 disposed on the machine base 200. The structure of each part is described in detail below.

[0055] Please see Figure 3 The hydraulic assembly 300 includes a support frame 310, a first actuator 320 mounted on the support frame 310, and a punch assembly 330 driven downward by the first actuator 320. The first actuator 320 is preferably a hydraulic cylinder, which is vertically mounted on the support frame 310. The punch assembly 330 includes a punch fixing plate 331 and a punch mounted on the lower surface of the punch fixing plate 331. The upper surface of the punch fixing plate 331 is fixed to the piston rod of the hydraulic cylinder via a connecting seat 334.

[0056] During the operation of the hydraulic assembly 300, the punch presses down and comes into contact with the mold assembly 400. See also... Figure 4 In this utility model, the punch includes a circular punch 332 and a pair of square punches 333, wherein the circular punch 332 is installed in the middle of the punch fixing plate 331, and the pair of square punches 333 are installed on both sides of the circular punch 332.

[0057] Please see Figure 3-4 In some embodiments, a guide rod 335 is provided at each of the four corners of the upper surface of the punch fixing plate 331, and a guide hole matching the guide rod 335 is opened at the corresponding position on the support frame 310, and a guide sleeve 311 is installed in the guide hole. The guide rod 335 on the upper surface of the punch fixing plate 331 passes through the guide sleeve 311, thereby guiding the lifting and lowering of the punch assembly 330.

[0058] Please see Figure 3-4 In some embodiments, a limiting rod 336 is provided at each of the four corners of the lower surface of the punch fixing plate 331, and a buffer rod 337 matching the limiting rod 336 is provided at the corresponding position on the surface of the machine base 200. The limiting rod 336 and the buffer rod 337 can play the role of limiting and buffering. During the pressing process, the punch assembly 330 descends and gradually applies pressure to the mold assembly 400 until the limiting rod 336 abuts against the corresponding buffer rod 337.

[0059] Please see Figure 5 The mold assembly 400 includes a mold track 410, a forming mold 500, and a second driver 420, with one end of the mold track 410 located below the punch assembly 330. The forming mold 500 is used to hold the welding ring 100 to be formed and is configured to slide on the mold track 410 driven by the second driver 420.

[0060] Please see Figure 6 The forming mold 500 includes a lower mold base 510, an inner mold sleeve 520 disposed on the lower mold base 510, a pair of outer mold sleeves 540, a floating mold core 530, and a pair of pushing components 550. The specific structure of these parts is described in detail below with reference to the accompanying drawings.

[0061] Please see Figure 7 The lower mold base 510 is a square component. For ease of description, the extension direction of the long side of the lower mold base 510 is taken as the X-axis, the extension direction of the short plate of the lower mold base 510 is taken as the Y-axis, and the vertical direction is taken as the Z-axis. In some embodiments of this utility model, the lower mold base 510 includes a bottom template 511 and a lower template 512 fixed on the bottom template 511. Connecting plates 513 are installed on both short plates of the lower mold base 510, and these connecting plates 513 are connected to the second driver 420. The second driver 420 can drive the shaping mold 500, which carries the welding iron ring 100, from the loading station to below the hydraulic component 300 for pressing and shaping. After pressing and shaping, the linear driver drives the shaping mold 500 back to the loading station, and the shaped welding iron ring 100 is removed from the shaping mold 500 by the material handling device. In this embodiment, the second driver 420 is a miniature cylinder. Limiting blocks 411 are also provided at both ends of the mold track 410 to block and limit the position of the forming mold 500.

[0062] Please see Figure 8 The inner mold sleeve 520 includes an annular base 521 and a plurality of sector-shaped pressure blocks 522 evenly distributed circumferentially on the annular base 521. The plurality of sector-shaped pressure blocks 522 are configured to slide radially along the annular base 521. Each sector-shaped pressure block 522 has an arc-shaped step portion 5221 formed on its outer peripheral surface. The arc-shaped step portions 5221 on the plurality of sector-shaped pressure blocks 522 together form a circular support for placing the welding iron ring 100 to be shaped. In a preferred embodiment, the number of sector-shaped pressure blocks 522 is 6.

[0063] In some embodiments of this utility model, a through positioning hole 5121 is provided on the lower template 512, and an annular base 521 is disposed in the positioning hole 5121 and abuts against the inner wall surface of the positioning hole 5121, with its upper end protruding from the positioning hole 5121. The positioning hole 5121 on the lower template 512 can limit the annular base 521 on the horizontal plane.

[0064] To enable the fan-shaped pressure block 522 to slide radially on the annular base 521, in some embodiments, a radially extending guide groove 5222 is formed on the lower surface of each fan-shaped pressure block 522. A guide block 5212 matching the shape of the guide groove 5222 is installed at a corresponding position on the annular base 521, and the guide block 5212 is embedded in the guide groove 5222 of the fan-shaped pressure block 522. In this way, the fan-shaped pressure block 522 can slide radially on the annular base 521 through the sliding engagement between the guide block 5212 and the guide groove 5222. To achieve the positioning of the fan-shaped pressure block 522 in the Z-axis direction, the guide groove 5222 is preferably a wedge-shaped groove, such as a dovetail groove. In some embodiments, a groove 5211 is formed on the annular base 521, and the guide block 5212 is installed in the groove 5211.

[0065] Please see Figure 9 The floating mold core 530 is disposed within the inner ring of the annular base 521 and is floatingly mounted on the lower mold base 510. The floating mold core 530 has multiple mating surfaces 531 corresponding one-to-one with the multiple sector-shaped pressure blocks 522; the floating mold core 530 abuts against the multiple sector-shaped pressure blocks 522 through the multiple mating surfaces 531. See also... Figure 5 In some embodiments, a plurality of first elastic elements 535 are fixed on the bottom template 511, and the floating mold core 530 has stepped holes 533 corresponding to the plurality of first elastic elements 535. The plurality of first elastic elements 535 extend into and abut against the stepped holes 533, thereby causing the floating mold core 530 to float on the bottom template 511. In this invention, the aforementioned first elastic elements 535 can be various elastic elements, including but not limited to springs.

[0066] Please see Figure 10 In some preferred embodiments, at least one guide post 536, preferably a pair of guide posts 536, is fixed on the bottom template 511. The floating mold core 530 has guide holes 534 corresponding to the guide posts 536, and the guide posts 536 pass through the guide holes 534 of the floating mold core 530, thereby guiding the lifting and lowering of the floating mold core 530, ensuring that the floating mold core 530 can only move in the Z-axis direction. In a preferred embodiment, the guide holes 534 are also stepped holes, and the top of the guide post 536 has a limiting retaining ring, thereby limiting the rising position of the floating mold core 530.

[0067] In this invention, the inner circumferential surface of the fan-shaped pressure block 522 and the mating surface 531 of the floating mold core 530 are both inclined surfaces that gradually move away from the center of the annular base 521 from bottom to top. This allows the floating mold core 530 to apply a pushing force to the fan-shaped pressure block 522 during its descent, causing multiple fan-shaped pressure blocks 522 to slide radially and spread outwards. In a preferred embodiment, the number of fan-shaped pressure blocks 522 is six, and correspondingly, the floating mold core 530 has six mating surfaces 531. In this case, the floating mold core 530 is a regular hexagonal prism that is thinner at the bottom and thicker at the top.

[0068] Please see Figure 8 and 9 In some preferred embodiments, each sector-shaped pressing block 522 has a first positioning groove 5223 on its inner circumferential surface, and the corresponding mating surface 531 of the floating mold core 530 has a first positioning protrusion 532 that matches the first positioning groove 5223. The first positioning protrusion 532 is embedded in the first positioning groove 5223, thereby realizing the guiding positioning of the sector-shaped pressing block 522. Similarly, the first positioning groove 5223 is preferably a wedge-shaped groove, such as a dovetail groove.

[0069] Please see Figure 11 Each pair of outer mold sleeves 540 has a semi-circular pressing groove 541 on its opposite surface that matches the outer peripheral surface of multiple fan-shaped pressing blocks 522, and the pair of outer mold sleeves 540 clamps the multiple fan-shaped pressing blocks 522 in the middle through the semi-circular pressing grooves 541. It can be understood that since the outer peripheral surface of the fan-shaped pressing block 522 has an arc-shaped step portion 5221, the surface of the outer mold sleeve 540 also has an arc-shaped step surface that matches it.

[0070] In some embodiments, the shaping mold 500 further includes a limiting component 560. See also... Figure 11 The limiting component 560 includes a base plate 561, which is disposed on the lower template 512 and has a through hole 5611 in its middle. The upper end of the annular base 521 passes through the through hole 5611 and abuts against the inner wall of the through hole 5611, while the outer mold sleeve 540 is supported on the base plate 561. Both sides of the base plate 561 along the Y-axis direction are provided with baffles 562, which are preferably integrally formed with the base plate 561, for limiting the outer mold sleeve 540 in the Y-axis direction. At least one lower pressing block 563 is also fixedly installed on the baffle 562, which presses against the surface of the outer mold sleeve 540 from above, for limiting the outer mold sleeve 540 in the Z-axis direction. Therefore, by setting the limiting component 560, the degree of freedom of the outer mold sleeve 540 in the Y-axis and Z-axis is restricted, so that the outer mold sleeve 540 can only move in the X-axis direction.

[0071] Please see Figure 12A pair of pushing components 550 are respectively disposed on both sides of an outer mold sleeve 540 along the X-axis direction. Each pushing component 550 includes a fixed stop 551 fixed on the lower mold base 510 and a floating push block 552 floatingly disposed on the lower mold base 510. Each floating push block 552 is located between the corresponding fixed stop 551 and the outer mold sleeve 540, and has a first end face and a second end face that are opposite to each other, wherein the first end face abuts against the fixed stop 551 and the second end face abuts against the outer mold sleeve 540.

[0072] In this invention, the abutting surfaces of the floating push block 552 and the outer mold sleeve 540 are both inclined surfaces that gradually approach the center of the annular base 521 from bottom to top. Therefore, during the descent of the floating push block 552, a pushing force can be applied to the outer mold sleeve 540, causing the outer mold sleeve 540 to move toward the fan-shaped pressure block 522 along the X-axis.

[0073] In some embodiments, a plurality of second elastic elements are fixed on the lower template 512, and the lower end face of the floating push block 552 has blind holes corresponding to the plurality of second elastic elements. The plurality of second elastic elements extend into the blind holes of the floating push block 552, thereby causing the floating push block 552 to float on the lower template 512. In this invention, the aforementioned second elastic elements can be various elastic components, including but not limited to springs.

[0074] In some embodiments, the fixed stop 551 has a second positioning groove 5511, and the first end face of the floating push block 552 has a second positioning protrusion 5521 that matches the second positioning groove 5511. The second positioning protrusion 5521 of the floating push block 552 is embedded in the second positioning groove 5511 of the fixed stop 551, thereby restricting the degrees of freedom of the floating push block 552 in the X-axis and Y-axis directions, and it can only move in the Z-axis direction.

[0075] In some embodiments of this utility model, under natural conditions, the height of the floating mold core 530 and the floating push block 552 is preferably higher than the height of the fan-shaped pressure block 522 and the outer mold sleeve 540, so that the hydraulic component 300 can contact the floating mold core 530 and the floating push block 552 first during the descent process, thereby applying force to press down.

[0076] In this utility model, the principle of using the hydraulic component 300 and the mold component 400 to shape the welded iron ring 100 is as follows:

[0077] In this invention, the arc-shaped stepped portions 5221 on the outer circumferential surfaces of multiple fan-shaped pressure blocks 522 together form a circular support platform on which the welding iron ring 100 to be shaped can be placed. Then, the hydraulic assembly 300 presses down from above, with the circular punch 332 pressing down on the floating mold core 530 and a pair of square punches 333 pressing down on the floating push block 552, causing the floating mold core 530 and the floating push block 552 to descend simultaneously. During this process, the multiple fan-shaped pressure blocks 522 are all subjected to the thrust applied by the floating mold core 530, thereby sliding radially to spread outward. At this time, the outer circumferential surface of the fan-shaped pressure block 522 contacts the inner ring of the welding iron ring 100 and presses it outward. Similarly, a pair of outer mold sleeves 540 are subjected to the thrust applied by the floating pressure blocks, thereby moving closer to each other along the X-axis direction, and the circumferential surface of their semi-circular pressure grooves 541 gradually contacts the outer ring of the welding iron ring 100 and presses it inward. Therefore, the shaping of the welded iron ring 100 is achieved and its roundness is improved by the squeezing action of the fan-shaped pressure block 522 and the outer mold sleeve 540, which are one inside and one outside.

[0078] Please see Figure 13 The feeding assembly 600 is disposed on one side of the mold assembly 400 and is used for feeding the welding iron ring 100 to be shaped. In some embodiments, the feeding assembly 600 includes a rodless cylinder 610 and a disc-shaped fixture 620 driven by the rodless cylinder 610, the disc-shaped fixture 620 being used to place the welding iron ring 100 to be shaped.

[0079] Please see Figure 13 The discharge assembly 700 is located on the other side of the mold assembly 400 and is used for unloading the shaped welding iron ring 100. In some embodiments, the discharge assembly 700 is a belt conveyor mechanism 710.

[0080] Please see Figure 13 In some embodiments, the shaping device further includes a detection component 800, which is preferably disposed between the mold component 400 and the discharge component 700, for detecting the roundness of the shaped welded iron ring 100. In this embodiment, the detection component 800 includes a detection platform 810 and a CCD camera 820 located above the detection platform 810. After shaping, the welded iron ring 100 is transported to the detection platform 810, where the CCD camera 820 takes a picture to detect the roundness of the shaped welded iron ring 100.

[0081] Please see Figure 13The gripping and transferring component 900 is used to grip the welding iron ring 100 to be shaped from the feeding component 600 and transfer it to the shaping mold 500; it also grips the shaped welding iron ring 100 and transfers it to the detection component 800 for detection, or to the discharge component 700 for discharge. In some embodiments, the gripping and transferring component 900 includes a synchronous belt slide 910 and a gripping module driven by the synchronous belt slide 910, wherein the gripping module includes a slide cylinder 920 and a gripper cylinder module 930 mounted on the slide cylinder 920. The gripper cylinder module 930 can conveniently grip the welding iron ring 100, while the synchronous belt slide 910 can realize the transfer of the welding iron ring 100 between the feeding component 600, the mold component 400, the detection component 800, and the discharge component 700.

[0082] Please see Figure 2 and Figure 13 In a preferred embodiment, the hydraulic components 300 are a pair, arranged side-by-side on the machine base 200. Correspondingly, the mold components 400 are also a pair, each located below the pair of hydraulic components 300. In this embodiment, by setting a pair of side-by-side hydraulic components 300, the welded iron ring 100 can be pressed and shaped twice, which helps to further improve the roundness of the welded iron ring 100. For ease of description, the pair of mold components 400 are respectively named the first mold component A and the second mold component B.

[0083] In the above embodiment, the detection component 800 is disposed between a pair of mold components 400, and the gripping module in the gripping and transferring component 900 is a dual-station gripping module, which includes a pair of synchronously moving gripper cylinder modules 930. Using a dual-station gripping module can greatly improve the efficiency of gripping and handling. The specific handling process is as follows:

[0084] First, the dual-station clamping module grabs the welding iron ring 100 to be shaped in the feeding component 600 and the welding iron ring 100 to be shaped once in the first mold component A, respectively. Then, it moves one station and places the welding iron ring 100 to be shaped on the first mold component A and places the welding iron ring 100 to be shaped once on the inspection platform 810.

[0085] Then, the dual-station clamping module moves one station to grab the welding iron ring 100 that has been shaped once on the detection platform 810 and the welding iron ring 100 that has been shaped twice in the second mold assembly B.
