Description

Technical Field

[0001] This utility model relates to the field of machining and forming, and in particular to a high-toughness ball pin structure forming device. Background Technology

[0002] As an important component of mechanical connectors, ball joints are widely used in automotive suspension systems, engineering machinery joints, and other applications. With the development of industrial technology, the performance requirements for ball joints are increasing, especially in terms of high strength and high toughness. Currently, the industry mainly produces ball joints through forging and casting, but these methods have certain limitations in terms of forming accuracy, material utilization, and product performance.

[0003] A search revealed a Chinese publication number (CN203170784U) for a spherical pin forming device, belonging to the field of pin forming molds. It includes a workpiece, an upper mold, and a lower mold with a blind hole corresponding to the upper mold position. The depth of the blind hole is less than the length of the workpiece, and the diameter of the blind hole matches the diameter of the workpiece. It also includes a spherical groove, which is disposed on the upper mold at a position corresponding to the blind hole. This invention offers the advantages of rapid pin forming, neat and stable workpieces, and no need for secondary grinding of the workpiece.

[0004] The aforementioned patent description mentions that "one end of the workpiece is heated to 800-900°C, then placed in a blind hole, exposing the hot end outside the blind hole, and the upper mold is closed." Without a cooling cycle, the temperature inside the mold becomes excessively high and uneven, leading to significant dimensional deviations in the ball pin structure during cooling and shrinkage. Key dimensions such as the diameter and length of the ball pin will exceed tolerances, affecting its fit with other components and reducing the assembly quality of the product. Without effective cooling, residual stress inside the product is high, and during subsequent use, the ball pin will deform due to stress release, further affecting its dimensional stability and performance. To address these issues, a high-toughness ball pin structure forming device is proposed. Utility Model Content

[0005] This invention proposes a high-toughness ball pin structure forming device, which aims to improve the problem that some existing high-toughness ball pin structure forming devices cannot prevent the backflow of circulating coolant.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-toughness ball pin structure forming device includes a mounting frame, a cooling water tank is externally connected to the mounting frame, a water outlet pipe is fixedly connected to the bottom right side of the cooling water tank, a return pipe is fixedly connected to the bottom left side of the cooling water tank, and an anti-backflow mechanism is fixedly connected to the outside of the return pipe. The anti-backflow mechanism has a backflow housing fixedly connected inside, a cross-shaped placement bracket fixedly connected outside the backflow housing, a mounting housing fixedly connected to the front side of the cross-shaped placement bracket, a sliding rod slidably connected to the outside of the mounting housing, a sealing plate fixedly connected to the front side of the sliding rod, a reset assembly sleeved on the outside of the sliding rod, a sealing ring fixedly connected inside the backflow housing, the outside of the backflow housing fixedly connected to the outside of the backflow pipe, and a pump body fixedly connected to the outside of the backflow pipe.

[0007] The above solution utilizes a mounting bracket paired with a cooling water tank to ensure adequate cooling during the molding process. The anti-backflow mechanism is crucial; the sealing ring inside the backflow housing works in conjunction with the sealing plate at the front end of the sliding rod to prevent coolant backflow. The pump body, in conjunction with the backflow pipe, maintains coolant circulation, while the cross-shaped support bracket and mounting housing provide stable support for all components, ensuring stable operation of the device.

[0008] As a further description of the above technical solution: The reset assembly includes a spring, which is sleeved on the outside of the sliding rod.

[0009] With the above solution: Spring 1 is tightly fitted outside the sliding rod, with one end firmly against the mounting housing and the other end tightly against the sealing plate. When the coolant flows normally, the pressure generated by the pump body pushes open the sealing plate, and Spring 1 is compressed. Once the pump body stops working, Spring 1 quickly rebounds, pushing the sealing plate back to its original position, tightly sealing the return port and preventing coolant backflow.

[0010] As a further description of the above technical solution: The mounting bracket has connecting cylinders fixedly connected to both the left and right sides inside. A support rod is fixedly connected inside the connecting cylinder. A top plate is fixedly connected to the top of the support rod. A fixed base plate is fixedly connected to the bottom of the support rod. A lower mold is connected to the top of the fixed base plate. A sealing strip is fixedly connected to the top of the lower mold. A disassembly and assembly mechanism is slidably connected inside the sealing strip. A limit ring is fixedly connected to the outside of the support rod.

[0011] The above solution utilizes connecting cylinders on both sides of the mounting frame to provide stable support for the support rod. The support rod connects to a top plate and a fixed base plate, forming a stable frame. The lower mold on the fixed base plate is used for ball pin forming, and its top sealing strip not only prevents material spillage but also facilitates the sliding of the disassembly and assembly mechanism. Limiting rings restrict the position of components, ensuring stable and precise operation of the entire device.

[0012] As a further description of the above technical solution: The disassembly and assembly mechanism includes a sliding lever, a pull plate is fixedly connected to the outer top of the sliding lever, a cavity is opened inside the sealing strip, a limit plate is slidably connected inside the cavity, a spring is sleeved on the outside of the sliding lever, and the outside of the sliding lever is slidably connected to the inside of the sealing strip.

[0013] With the above solution: the sliding rod slides flexibly within the sealing strip, and its top pull plate facilitates operation. Inside the sealing strip cavity, the limiting plate moves with the sliding rod, providing precise positioning. The second spring, fitted around the outside of the sliding rod, normally pushes the sliding rod to the preset position, facilitating quick assembly and disassembly of the mold components and greatly improving the ease of use and work efficiency of the device.

[0014] As a further description of the above technical solution: A hydraulic cylinder is fixedly connected to the outside of the top plate, and an upper mold is fixedly connected to the drive end of the hydraulic cylinder. Connecting blocks are fixedly connected to the left and right sides of the outside of the upper mold.

[0015] The above solution involves a hydraulic cylinder securely connected to the outside of the top plate, providing powerful energy to the device. The hydraulic cylinder drive end is connected to the upper mold. When the hydraulic cylinder is activated, it can precisely drive the upper mold to move up and down. The connecting blocks on the left and right sides of the upper mold further enhance its connection stability with other components, ensuring that the ball pin forming process is efficient and precise.

[0016] As a further description of the above technical solution: A connecting rod is slidably connected to the outside of the connecting block, and a spring is sleeved on the outside of the connecting rod. A water inlet pipe is fixedly connected to the top of the cooling water tank.

[0017] The above solution makes the upper mold move more smoothly under the drive of the hydraulic cylinder. The spring three sleeved on the outside of the connecting rod can play a buffering role when the mold moves, reducing the impact force and extending the service life of the device. The water inlet pipe at the top of the cooling water tank is the channel for replenishing coolant, continuously providing cooling water to the device and ensuring that the temperature is effectively controlled during the ball pin forming process.

[0018] As a further description of the above technical solution: The outer side of the sealing ring is in contact with the outer side of the sealing plate, and the outer side of the sealing plate is slidably connected to the inside of the return housing.

[0019] With the above solution: the sealing ring is tightly attached to the inner wall of the return housing, while the sealing plate can slide smoothly inside the return housing. When the coolant is flowing normally, the sealing plate slides as needed. Once there is a backflow tendency, the sealing plate quickly fits into the sealing ring, tightly preventing the coolant from flowing back and ensuring the stable operation of the entire cooling cycle system.

[0020] As a further description of the above technical solution: One end of the sliding rod is fixedly connected to the outside of the sealing plate, and the other end of the sliding rod is fixedly connected to the outside of the mounting housing.

[0021] The above solution allows for precise sliding within the return housing. When the coolant pressure changes, the sliding rod responds promptly, ensuring that the sealing plate and sealing ring fit tightly or separate, effectively preventing coolant backflow.

[0022] This utility model has the following beneficial effects: 1. In this utility model, the sealing plate can then slide inside the mounting housing via the sliding rod, which in turn causes the spring outside the sliding rod to deform, allowing water to flow through the cross-shaped placement bracket into the return pipe, thus returning the water to the interior of the cooling water tank. When the water circulation stops, the spring rebounds, allowing the sealing plate and sealing ring to fit tightly together, preventing the water from flowing back.

[0023] 2. In this utility model, by pulling the pull plate, the pull plate drives the limiting plate to slide inside the cavity through the sliding latch, so that the limiting plate can compress the second spring, thereby causing the second spring to deform, and then the sliding latch can separate from the bottom of the fixed base plate, thereby realizing the disassembly of the lower mold. When installing the new lower mold, by releasing the pull plate, the second spring rebounds, and then the sliding latch can engage with the fixed base plate. Attached Figure Description

When the coolant is flowing back normally, the two separate, and the coolant passes smoothly. When the coolant flows back, the sealing plate 1006 is tightly fitted with the sealing ring 1007 under the action of the spring 1005 to prevent the coolant from flowing back and ensure the normal circulation of the coolant. The outer part of the return housing 1001 is fixedly connected to the outside of the return pipe 9. A pump body 11 is fixedly connected to the outside of the return pipe 9. The function of the pump body 11 is to provide power for the circulation of the coolant, so that the coolant can form a stable circulation loop between the cooling water tank 6, the outlet pipe 8, the mold and the return pipe 9, ensuring the cooling effect of the mold and improving the quality and efficiency of ball pin forming. Specifically, the mounting frame 5, after rust removal and painting, is first erected to provide support for all components. A cooling water tank 6 is connected to the mounting frame 5.

The cavity 1403 is... The space is specially designed to accommodate components such as the limiting plate 1404, the sliding rod 1401, and the second spring 1405. The limiting plate 1404 is slidably connected inside the cavity 1403. The surface of the limiting plate 1404 is smooth, which can not only ensure free sliding within the cavity 1403, but also play a good limiting role.

All components work together to ensure the normal operation of the molding device, especially playing a role in the installation and disassembly of mold-related components.

[0029] Reference Figures 4 to 6A hydraulic cylinder 20 is fixedly connected to the outside of the top plate 3. The hydraulic cylinder 20 is a heavy-duty hydraulic cylinder that meets industrial standards and has high load capacity and stable power output performance. Its model is precisely selected according to the weight of the upper mold 16, the forming pressure required, and the stroke. The drive end of the hydraulic cylinder 20 is fixedly connected to the upper mold 16. The shape and internal structure of the upper mold 16 are precisely designed and processed according to the design shape and size of the ball pin. The surface of the internal forming cavity is finely ground and polished. Connecting blocks 17 are fixedly connected to the left and right sides of the upper mold 16. The connecting blocks 17 are fixed to the outside of the upper mold 16 by welding. Welding materials that match the materials of the connecting blocks 17 and the upper mold 16 are selected to ensure a firm weld. A connecting rod 18 is slidably connected to the outside of the connecting blocks 17. The two ends of the connecting rod 18 are limited by limiting devices. To prevent the connecting rod 18 from detaching from the connecting block 17 during sliding, and to ensure that the connecting rod 18 slides stably within the connecting block 17, providing guidance and auxiliary support for the movement of the upper mold 16, a spring 3 19 is sleeved on the outside of the connecting rod 18. The outer diameter of the spring 3 19 is determined according to the outer diameter of the connecting rod 18 and the installation space to ensure that it can be smoothly sleeved on the connecting rod 18. A water inlet pipe 7 is fixedly connected to the top of the cooling water tank 6. The diameter of the water inlet pipe 7 is determined according to the flow rate requirement of the coolant. One end of the water inlet pipe 7 is sealed to the top of the cooling water tank 6. The connection is sealed with a sealing ring and a pipe clamp to ensure that the coolant does not leak. The outside of the sealing ring 1007 is in contact with the outside of the sealing plate 1006. The outside of the sealing plate 1006 is slidably connected to the inside of the return housing 1001. One end of the sliding rod 1004 is fixedly connected to the outside of the sealing plate 1006, and the other end of the sliding rod 1004 is fixedly connected to the outside of the mounting housing 1003. Specifically, based on parameters such as the weight, forming pressure, and stroke of the upper mold 16, a heavy-duty hydraulic cylinder 20 conforming to industrial standards is precisely selected on the top plate 3. The drive end of the hydraulic cylinder 20 is connected to the finely machined upper mold 16, and the connecting blocks 17 on both sides are fixed by bolts and slidably connected to the connecting rod 18 with springs 19. The connecting rod 18 slides stably by a limiting device, guiding and supporting the upper mold 16. The top of the cooling water tank 6 is connected to the water inlet pipe 7 with a sealing ring and a pipe clamp to ensure that the coolant does not leak. Inside the anti-backflow mechanism 10, the sealing plate 1006 slides inside the backflow housing 1001, with one end connected to the sliding rod 1004 and the other end of the sliding rod 1004 connected to the mounting housing 1003. Normally, the sealing plate 1006 is separated from the sealing ring 1007, and during backflow, it fits together to prevent backflow. All components work together to ensure the forming of the ball pin.

[0030] Working principle: When preventing backflow of cooling circulating water, the pump body 11 is activated, allowing water to enter the interior of the return housing 1001. At this time, the pump body 11 causes the water to squeeze the sealing plate 1006, which in turn allows the sealing plate 1006 to slide inside the mounting housing 1003 via the sliding rod 1004. This causes the spring 1005 outside the sliding rod 1004 to deform, allowing the water to flow into the return pipe 9 through the cross-shaped bracket 1002, thus returning the water to the interior of the cooling water tank 6. When the water circulation stops, the spring 1005 rebounds, allowing the sealing plate 1006 to fit tightly against the sealing ring 1007, thus preventing backflow of water. When replacing the lower mold 12, by pulling the pull plate 1402, the pull plate 1402 causes the sliding rod 1401 to drive the limiting plate 1404 to slide inside the cavity 1403. Under the sliding of the limiting plate 1404, the limiting plate 1404 can compress the second spring 1405, which in turn causes the second spring 1405 to deform, thereby separating the sliding rod 1401 from the bottom of the fixed base plate 1, thus enabling the disassembly of the lower mold 12. When installing the new lower mold 12, by releasing the pull plate 1402, the second spring 1405 rebounds, thereby enabling the sliding rod 1401 to engage with the fixed base plate 1.
