Abstract
Description
Technical Field
[0001] This application relates to the technical field of pipe joint processing equipment, specifically a chamfering machine for tee joints that facilitates material transfer. Background Technology
[0002] In the field of pipe fitting manufacturing, tee fittings are key components for achieving branch connections in pipelines. The ends of their three interfaces typically require chamfering to remove burrs and ensure the sealing and safety of the assembled pipeline. To improve chamfering efficiency and precision, automated chamfering equipment is widely used in the industry for processing tee fittings.
[0003] Existing tee connector chamfering equipment generally consists of a base, three reciprocating chamfering machines mounted in a "T" shape on the base, a lower clamp fixed to the base, and an upper clamp positioned directly above the lower clamp via a drive mechanism. The lower clamp corresponds one-to-one with the three chamfering machines and is used to support and position the tee connector; the upper clamp works in conjunction with the lower clamp to secure the tee connector. During processing, the operator places the tee connector into the mold cavity of the lower clamp, and the drive mechanism moves the upper clamp downwards, causing it to fit tightly against the lower clamp, thus firmly fixing the tee connector. Subsequently, the controller starts the three chamfering machines to move synchronously towards the tee connector, completing the chamfering operation on its three interfaces simultaneously.
[0004] However, even after chamfering, the removal of the tee connector still relies on manual operation. Because the tee connector is curved and embedded in the mold cavity of the lower clamp, operators cannot remove it by gripping the outside; they can only grasp one end of the connector to remove it. During chamfering, the friction between the chamfering machine and the connector end generates heat, causing the temperature at the interface to rise. At this point, the operator's hands are at high risk of burns from contact with the hot interface, affecting operational safety, reducing removal efficiency, and causing inconvenience to production.
[0005] Therefore, this application provides a tee joint chamfering machine that facilitates material transfer, in order to solve the above-mentioned problems. Utility Model Content
[0006] This application provides a tee connector chamfering machine that facilitates material transfer, aiming to solve the problems mentioned in the background art, such as the need for manual removal of the tee connector from the mold cavity of the lower clamp after the chamfering operation of the existing tee connector chamfering equipment. Since the tee connector is located in the lower clamp, it cannot be directly pinched, and only its opening can be pinched. Furthermore, the opening has a certain temperature after chamfering friction, which can easily cause burns to the operator's hands, making it inconvenient to remove the part.
[0007] To achieve the above object, the present application provides the following technical solution: A three-way joint chamfering machine for facilitating material transmission, comprising a machine base, three reciprocally movable chamfering machine bodies mounted on the machine base in a "T" shape, a lower fixture fixed to the machine base, and an upper fixture disposed directly above the lower fixture through a driving mechanism. Among them, the lower fixture corresponds to the three chamfering machine bodies one by one;
[0008] In order to facilitate ejecting the three-way joint from the mold cavity of the lower fixture: An ejecting mechanism is provided inside the lower fixture. The ejecting mechanism includes a ejector pin slidably inserted into the mold cavity of the lower fixture and a spring disposed inside the lower fixture for driving the ejector pin to move in the direction close to the upper fixture. Through the ejecting mechanism, the three-way joint can be automatically ejected from the mold cavity of the lower fixture, enabling the operator to hold the outside of the three-way joint to complete the picking operation, avoiding burns caused by contacting the high-temperature opening, improving the safety of loading and unloading, and enhancing the overall processing efficiency.
[0009] Preferably, in order to prevent the ejector pin from rotating axially: The ejector pin is square-shaped. Preventing the ejector pin from rotating axially ensures that the three-way joint maintains a stable posture during the ejection process, avoiding collisions with equipment components due to rotation, and ensuring the smoothness of the picking operation.
[0010] Preferably, in order to facilitate pre-positioning of the ejector pin for the three-way joint: A cross-shaped support plate is fixedly connected to the end of the ejector pin away from the spring. The radian of the upper surface of the cross-shaped support plate is consistent with the external radian of the lower surface of the three-way joint. A groove adapted to the cross-shaped support plate is opened in the mold cavity of the lower fixture. When the three-way joint is located in the mold cavity of the lower fixture, the cross-shaped support plate is located in the groove. The cross-shaped support plate can form a stable support for the bottom of the three-way joint. Its radian adaptation design can achieve pre-positioning of the three-way joint and prevent offset during placement; the groove can accommodate the cross-shaped support plate during the positioning of the three-way joint, avoiding affecting the precise positioning of the lower fixture for the three-way joint.
[0011] Preferably, in order to prevent the ejector pin from detaching from the lower fixture: A limiting groove for placing the spring is opened inside the lower fixture, and a limiting plate is disposed inside the limiting groove corresponding to the spring and the ejector pin. It can effectively limit the maximum upward movement distance of the ejector pin, prevent the ejector pin from detaching from the lower fixture due to excessive spring force, ensure the stable operation of the ejecting mechanism, and avoid equipment failures or processing interruptions caused by component detachment.
[0012] Preferably, the machine base is in a "convex" shape. It provides sufficient installation space for the "T" - shaped layout of the chamfering machine bodies, facilitates the compact arrangement of each component, and reduces the floor area of the equipment.
[0013] Preferably, the driving mechanism includes a bracket fixedly mounted on the base, a lifting plate disposed at the bottom of the bracket and slidably connected to the column of the bracket, and an electric push rod fixedly mounted on the top of the bracket. The output end of the electric push rod passes through the bracket via a circular hole and is fixedly connected to the lifting plate. The upper clamp is fixedly mounted on the bottom of the lifting plate. Using an electric push rod to drive the lifting plate enables smooth lifting and lowering of the upper clamp, ensuring uniform clamping force on the tee connector. The sliding connection structure between the bracket and the lifting plate ensures the movement accuracy of the upper clamp and improves positioning accuracy.
[0014] Preferably, to prevent the ejector pin from rapidly springing back, the chamfering machine also includes a hydraulic damper fixedly installed within the limiting groove. The output end of the hydraulic damper is fixedly connected to the limiting plate, and the spring is sleeved on the outside of the hydraulic damper. The hydraulic damper slows down the upward movement speed of the ejector pin, preventing the tee connector from being rapidly ejected due to excessive spring force, thus preventing collision damage or splashing when the tee connector pops out, and improving the safety of the part removal process.
[0015] This application utilizes a lifting mechanism to automatically eject the tee connector from the mold cavity of the lower clamp, allowing operators to handle the connector from the outside to remove parts, avoiding burns from contact with the high-temperature opening, improving the safety of loading and unloading, and increasing overall processing efficiency.
[0016] This application uses a hydraulic damper to slow down the upward movement speed of the ejector pin, preventing the tee connector from being ejected too quickly due to excessive spring force, thus preventing collision damage or splashing when the tee connector is ejected and improving the safety of the part removal process.

[0024] 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.
[0025] Example 1
[0026] This embodiment provides a tee joint chamfering machine for easy material transfer, such as... Figure 1-5 As shown, the chamfering machine includes a base 1, three reciprocating chamfering machine bodies 2 mounted in a "T" shape on the base 1, a lower clamp 3 fixed to the base 1, and an upper clamp 4 positioned directly above the lower clamp 3 via a drive mechanism 5. The lower clamp 3 corresponds one-to-one with the three chamfering machine bodies 2. To facilitate the ejection of the T-connector from the mold cavity of the lower clamp 3, a lifting mechanism 6 is provided inside the lower clamp 3. The lifting mechanism 6 includes an ejector pin 61 slidably inserted into the mold cavity of the lower clamp 3 and a spring 62 located inside the lower clamp 3 to drive the ejector pin 61 to move closer to the upper clamp 4. The lifting mechanism 6 automatically ejects the T-connector from the mold cavity of the lower clamp 3, allowing the operator to handle the T-connector from the outside to remove it, avoiding burns from contact with the high-temperature opening, improving loading and unloading safety, and increasing overall processing efficiency. When chamfering is required on the tee connector, simply place the tee connector on top of the ejector pin 61, then drive the upper clamp 4 downward via the drive mechanism 5, so that the upper clamp 4 fits on top of the tee connector, and continue to drive the tee connector downward until it enters the mold cavity of the lower clamp 3. Then, the controller drives the chamfering machine body 2 to perform the chamfering operation on the tee connector. After chamfering is completed, the drive mechanism 5 drives the upper clamp 4 upward to disengage from the lower clamp 3. At this point, with the cooperation of the spring 62 and the ejector pin 61, the tee connector is moved out of the mold cavity of the lower clamp 3, making it easy for a person to manually remove the tee connector by holding it from the outside.
[0027] To prevent axial rotation of the ejector pin 61, the ejector pin 61 is square in shape. This prevents axial rotation of the ejector pin 61, ensuring the tee connector maintains a stable posture during ejection, avoiding collisions with equipment components due to rotation, and ensuring smooth part removal operations. The square ejector pin 61 engages with the rectangular sliding hole of the lower clamp 3. The square structure's edges restrict the ejector pin 61's rotational freedom around the axial direction, allowing it only to slide up and down along the axial direction.
[0028] To facilitate the pre-positioning of the tee connector by the ejector pin 61, a cross support plate 63 is fixedly connected to the end of the ejector pin 61 away from the spring 62. The curvature of the upper surface of the cross support plate 63 matches the outer curvature of the lower surface of the tee connector. A groove 31 adapted to the cross support plate 63 is provided in the mold cavity of the lower clamp 3. When the tee connector is located in the mold cavity of the lower clamp 3, the cross support plate 63 is located in the groove 31. The cross support plate 63 can provide stable support for the bottom of the tee connector, and its curvature adaptation design can realize the pre-positioning of the tee connector and prevent displacement during placement. The groove 31 can accommodate the cross support plate 63 when the tee connector is positioned, so as not to affect the accurate positioning of the tee connector by the lower clamp 3. When placing the tee connector, the arc-shaped surface of the cross plate 63 fits against the bottom of the tee connector, and the horizontal displacement of the tee connector is limited by the shape matching; when the tee connector is pressed into the mold cavity of the lower clamp 3, the cross plate 63 moves down with the ejector pin 61 and is embedded in the groove 31, ensuring that the tee connector fits tightly against the lower clamp 3.
[0029] To prevent the ejector pin 61 from detaching from the lower clamp 3, a limiting groove 32 for accommodating the spring 62 is provided inside the lower clamp 3. A limiting plate 64 is provided inside the limiting groove 32 between the spring 62 and the ejector pin 61. This effectively limits the maximum upward movement distance of the ejector pin 61, preventing it from detaching from the lower clamp 3 due to excessive spring force from the spring 62, ensuring the stable operation of the lifting mechanism 6, and avoiding equipment malfunctions or processing interruptions caused by component detachment. The spring 62 is installed in the limiting groove 32, and the limiting plate 64 is fixed to the bottom of the ejector pin 61 and located within the limiting groove 32. When the ejector pin 61 moves upward, the limiting plate 64 contacts the top edge of the limiting groove 32, mechanically preventing the ejector pin 61 from moving further upward.
[0030] The base 1 is convex in shape. It provides ample installation space for the T-shaped layout of the chamfering machine body 2, facilitating the compact arrangement of various components and reducing the equipment's footprint. The protruding part of the convex base 1 can serve as a mounting platform for the chamfering machine body 2, while the widened bottom increases the contact area with the ground, enhancing the equipment's anti-tipping ability and ensuring the stability of the equipment during the chamfering process.
[0031] The drive mechanism 5 includes a bracket 51 fixedly mounted on the base 1, a lifting plate 52 located at the bottom of the bracket 51 and slidably connected to the column of the bracket 51, and an electric push rod 53 fixedly mounted on the top of the bracket 51. The output end of the electric push rod 53 passes through a round hole through the bracket 51 and is fixedly connected to the lifting plate 52. The upper clamp 4 is fixedly mounted on the bottom of the lifting plate 52. Using the electric push rod 53 to drive the lifting plate 52 enables smooth lifting and lowering of the upper clamp 4, ensuring uniform clamping force on the tee connector. The sliding connection structure between the bracket 51 and the lifting plate 52 ensures the moving accuracy of the upper clamp 4 and improves positioning accuracy. When the electric push rod 53 extends or retracts, it drives the lifting plate 52 to slide up and down along the column of the bracket 51. The lifting plate 52 synchronously drives the upper clamp 4 to move closer to or away from the lower clamp 3. The clamping and fixing of the tee connector is achieved through the contact between the upper clamp 4 and the lower clamp 3. The electric push rod 53 is model YRJ065.
[0032] Example 2
[0033] Unlike Embodiment 1, to prevent the ejector pin 61 from rapidly springing up, the chamfering machine also includes a hydraulic damper 7 fixedly installed in the limiting groove 32. The output end of the hydraulic damper 7 is fixedly connected to the limiting plate 64, and the spring 62 is sleeved on the outside of the hydraulic damper 7. This slows down the upward movement speed of the ejector pin 61, preventing the tee connector from being rapidly ejected due to excessive spring force of the spring 62, preventing collision damage or splashing when the tee connector pops out, and improving the safety of the part removal process. The hydraulic damper 7 and the spring 62 are installed in parallel. When the spring 62 pushes the ejector pin 61 upward, the hydraulic damper 7 generates resistance through internal oil damping, limiting the movement speed of the ejector pin 61 within a reasonable range, and achieving smooth ejection of the tee connector.
[0034] The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
[0035] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
[0036] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.
[0037] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto.
