Description

Technical Field

[0001] This application relates to the field of wheel spoke processing equipment technology, specifically a stretching device for wheel spoke processing. Background Technology

[0002] In the manufacturing of vehicles such as lawnmowers, ATVs, sightseeing vehicles, and golf carts, wheel spokes are a key component, and their processing technology is of paramount importance.

[0003] Currently, wheel spokes are typically produced using a circular plate stretching process. However, during the wheel spoke stretching process for the aforementioned vehicle types, the spokes are prone to getting stuck on the upper mold after processing. The current solution relies primarily on workers knocking them off the mold. This operation is not only cumbersome and time-consuming, but also generates debris that easily flies into workers' eyes, posing a serious threat to their safety and health and significantly impacting production safety and efficiency.

[0004] Therefore, this application provides a stretching device for wheel spoke processing to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a stretching device for wheel spoke processing, which aims to solve the problems mentioned in the background art, such as existing wheel spokes being easily stuck on the upper mold and difficult to demold after stretching.

[0006] To achieve the above objectives, this application provides the following technical solution: a stretching device for wheel spoke processing, comprising a frame, a lower die fixedly mounted on the frame, an upper die mounted above the lower die and adapted to the lower die, and a driving component for driving the upper die to move closer to or away from the lower die; To facilitate the demolding of the wheel spokes from the upper mold, a demolding mechanism is provided on the upper mold. This mechanism includes triangular plates symmetrically arranged on both sides of the upper mold and connecting rods fixedly connected to the upper ends of the triangular plates. The upper ends of the connecting rods are fixedly connected to the frame. The triangular plate design ensures that the sheet metal is not easily deformed. The triangular plates are made of high-strength sheet metal, such as stainless steel. During the stretching process of the wheel spokes, the circular plate is first placed on the lower mold. The driving component drives the upper mold to move downwards towards the lower mold, achieving the stretching and forming of the circular plate. After stretching is completed, the driving component drives the upper mold to reset. Since the wheel spokes are now fitted onto the upper mold, when the wheel spokes rise with the upper mold to contact the triangular plates, the upper mold continues to move upwards under the action of the driving component, while the triangular plates remain fixed in position. The wheel spokes gradually detach from the upper mold under the action of the triangular plates, thus completing automatic demolding.

[0007] Preferably, to prevent wear between the triangular plate and the outer wall of the upper mold, a plurality of ball bearings are rotatably embedded on the side of the triangular plate closest to the upper mold, and these ball bearings are in contact with the outer wall of the upper mold. The multiple ball bearings rotatably embedded on the side of the triangular plate closest to the upper mold effectively reduce wear between the triangular plate and the outer wall of the upper mold. During long-term use, if the triangular plate and the upper mold directly contact and rub against each other, it will cause damage to both surfaces, affecting the mold's accuracy and service life. The ball bearings change sliding friction into rolling friction, greatly reducing friction and extending the service life of both the mold and the triangular plate, while also ensuring machining accuracy.

[0008] Preferably, to prevent displacement of the triangular plates: symmetrical semicircular rings are provided on the upper mold, and the ends of the semicircular rings are fixedly connected to the two triangular plates respectively. The semicircular rings connect the two triangular plates together, effectively preventing displacement of the triangular plates during operation. If the triangular plates are displaced, their relative position with the upper mold will change, affecting the demolding effect and possibly damaging the mold and spokes. The fixing effect of the semicircular rings ensures the stability and reliability of the demolding mechanism, ensuring the normal operation of spoke processing.

[0009] Preferably, the frame comprises a base, a top plate, and support rods fixedly disposed at the four corners between the base and the top plate. The lower die is fixedly mounted on the base, and the drive component is disposed on the top plate. This frame structure, consisting of the base, top plate, and support rods, provides stable support for the entire stretching device. The base provides a stable mounting foundation for the lower die, the top plate provides the mounting position for the drive component, and the support rods at the four corners ensure the overall rigidity and stability of the frame. This stable frame structure ensures precise die alignment during the stretching process, improving the accuracy and quality of wheel spoke processing.

[0010] Preferably, the driving component includes a lifting plate fixedly mounted on the upper end of the upper mold and a hydraulic rod fixedly mounted on the frame. The output end of the hydraulic rod passes through the frame and is fixedly connected to the top of the lifting plate. A guide rod, fixedly connected to the lifting plate, is slidably inserted into the frame. The driving component, using a combination of the hydraulic rod and the lifting plate, along with the guide rod, enables precise control of the lifting movement of the upper mold. The hydraulic rod has a large driving force and precise stroke control capability, meeting the requirements of different spoke stretching processes. The lifting plate evenly transmits the force of the hydraulic rod to the upper mold, ensuring uniform force distribution. The guide rod ensures the stability and straightness of the upper mold during lifting, preventing deviation during movement and improving processing accuracy.

[0011] The demolding mechanism designed in this application significantly improves the efficiency and safety of wheel spoke processing. In traditional processing, wheel spokes are held in place by the upper mold and require manual hammering for demolding, which is cumbersome and poses safety hazards. This demolding mechanism, through the cooperation of a triangular plate and a connecting rod, automatically detaches the wheel spokes from the upper mold during mold resetting, avoiding manual hammering. This saves time, prevents debris from flying and injuring workers, and improves production efficiency and safety. Attached Figure Description

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0015] This embodiment provides a stretching device for wheel spoke processing, such as... Figure 1-3 As shown, the stretching device includes a frame 1, a lower die 2 fixedly mounted on the frame 1, an upper die 3 mounted above the lower die 2 and adapted to the lower die 2, and a drive component 4 for driving the upper die 3 to move closer to or away from the lower die 2. To facilitate the demolding of the wheel spokes from the upper mold 3, a demolding mechanism 5 is provided on the upper mold 3. The demolding mechanism 5 includes triangular plates 51 symmetrically arranged on both sides of the upper mold 3 and a connecting rod 52 fixedly connected to the upper end of the triangular plates 51. The upper end of the connecting rod 52 is fixedly connected to the frame 1. The design of the demolding mechanism 5 significantly improves the efficiency and safety of wheel spoke processing. In traditional processing, the wheel spokes, stuck on the upper mold 3, require manual hammering for demolding, which is cumbersome and poses safety hazards. This demolding mechanism 5, through the cooperation of the triangular plates 51 and the connecting rod 52, automatically detaches the wheel spokes from the upper mold 3 during mold resetting, avoiding manual hammering, saving time, preventing debris from flying and injuring workers, and improving production efficiency and safety. The design of the triangular plates 51 ensures that the sheet metal is not easily deformed. The triangular plates 51 are made of high-strength sheet metal, such as stainless steel. When stretching the wheel spokes, the round plate is first placed on the lower mold 2. The driving component 4 drives the upper mold 3 to move downwards and approach the lower mold 2, thereby stretching and forming the circular plate. After stretching is completed, the driving component 4 drives the upper mold 3 to reset. Since the spokes are now fitted onto the upper mold 3, when the spokes rise with the upper mold 3 to contact the triangular plate 51, the upper mold 3 continues to move upwards under the action of the driving component 4, while the position of the triangular plate 51 remains fixed. The spokes will gradually detach from the upper mold 3 under the action of the triangular plate 51, thus completing automatic demolding.

[0016] To prevent wear between the triangular plate 51 and the outer wall of the upper mold 3, multiple ball bearings 511 are rotatably embedded on the side of the triangular plate 51 closest to the upper mold 3, with the ball bearings 511 in contact with the outer wall of the upper mold 3. These ball bearings effectively reduce wear between the triangular plate 51 and the outer wall of the upper mold 3. During long-term use, direct contact and friction between the triangular plate 51 and the upper mold 3 would damage both surfaces, affecting the mold's accuracy and service life. The ball bearings 511 transform sliding friction into rolling friction, significantly reducing friction and extending the service life of both the mold and the triangular plate 51, while also ensuring machining accuracy. During the up-and-down movement of the upper mold 3, the ball bearings 511 rotate, thus preventing contact between the upper mold 3 and the triangular plate 51 and avoiding wear between them. Since the ball bearing 511 can rotate freely, it rolls along with the upper mold 3 as it moves upward, thus transforming the sliding friction between the triangular plate 51 and the upper mold 3 into the rolling friction of the ball bearing 511, reducing friction and avoiding wear caused by direct friction.

[0017] To prevent displacement of the triangular plates 51, semicircular rings 512 are symmetrically arranged on the upper mold 3, with the ends of the semicircular rings 512 fixedly connected to the two triangular plates 51 respectively. The semicircular rings 512 connect the two triangular plates 51 together, effectively preventing displacement of the triangular plates 51 during operation. If the triangular plates 51 are displaced, their relative position with the upper mold 3 will change, affecting the demolding effect and potentially damaging the mold and spokes. The fixing function of the semicircular rings 512 ensures the stability and reliability of the demolding mechanism 5, ensuring the normal processing of the spokes. The ends of the semicircular rings 512 are fixedly connected to the two triangular plates 51 respectively, forming an integral structure. During demolding, the semicircular rings 512 can withstand the external force on the triangular plates 51, distributing the force throughout the entire structure, thereby ensuring that the triangular plates 51 do not shift position under force, always maintaining the correct relative position with the upper mold 3, and achieving stable demolding operation.

[0018] The frame 1 consists of a base 11, a top plate 12, and support rods 13 fixedly installed at the four corners between the base 11 and the top plate 12. The lower die 2 is fixedly installed on the base 11, and the drive component 4 is installed on the top plate 12. The frame 1, composed of the base 11, top plate 12, and support rods 13, provides stable support for the entire stretching device. The base 11 provides a stable mounting foundation for the lower die 2, the top plate 12 provides the mounting position for the drive component 4, and the support rods 13 at the four corners ensure the overall rigidity and stability of the frame 1. The stable frame 1 structure ensures precise alignment of the die during the stretching process, improving the accuracy and quality of wheel spoke processing. The base 11 is placed on the working surface, providing support for the entire device. The lower die 2 is fixedly installed on the base 11, ensuring its position is fixed during the stretching process. The top plate 12 is connected to the base 11 via the support rods 13, providing a mounting platform for the drive component 4. The drive component 4 is installed on the top plate 12 and, through connection with the upper die 3, drives the upper die 3. During the stretching process, the frame 1 can withstand the forces generated by the mold and spokes, maintain structural stability, and ensure the normal progress of the stretching process.

[0019] The driving component 4 includes a lifting plate 41 fixedly mounted on the upper end of the upper mold 3 and a hydraulic rod 42 fixedly mounted on the frame 1. The output end of the hydraulic rod 42 passes through the frame 1 and is fixedly connected to the top of the lifting plate 41. A guide rod 43, fixedly connected to the lifting plate 41, is slidably inserted into the frame 1. The driving component 4, using a combination of the hydraulic rod 42 and the lifting plate 41, along with the guide rod 43, can precisely control the lifting and lowering movement of the upper mold 3. The hydraulic rod 42 has a large driving force and precise stroke control capability, which can meet the requirements of different spoke stretching processes. The lifting plate 41 evenly transmits the force of the hydraulic rod 42 to the upper mold 3, ensuring uniform force distribution on the upper mold 3. The guide rod 43 ensures the stability and straightness of the upper mold 3 during the lifting process, preventing the upper mold 3 from shifting during movement and improving processing accuracy. When the hydraulic rod 42 is working, the extension and retraction of its output end drives the lifting plate 41 to move up and down. The lifting plate 41 is fixedly connected to the upper mold 3, thereby realizing the up and down movement of the upper mold 3. During the lifting process, the guide rod 43 is slidably inserted into the frame 1 and fixedly connected to the lifting plate 41. The guide rod 43 plays a guiding role, ensuring that the upper mold 3 moves up and down along a straight line, avoiding shaking or displacement of the upper mold 3 during the movement, and ensuring the accuracy of the stretching process.
