Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing equipment technology, and specifically to a forging copper pipe fitting forming device. Background Technology

[0002] Copper pipe fittings are core components in water supply and drainage systems, bathroom hardware, and refrigeration and heat exchange equipment, widely used due to their excellent corrosion resistance, thermal conductivity, and mechanical sealing performance. Currently, mass production of copper pipe fittings mainly employs hot forging (red stamping) forming technology. This process achieves the target structure through the plastic deformation of a high-temperature copper billet within a closed die cavity. While this process offers high forming precision and a dense product structure, the die must repeatedly withstand high-temperature and high-pressure impacts during production. The quality of the release agent spraying process directly determines the surface quality of the forgings and the lifespan of the die.

[0003] Currently, the application of release agent for forged copper pipe fittings is mainly done manually. In this manual method, after the forging equipment opens the mold and removes the finished forging, the operator holds a spray gun and inserts it into the parting space of the upper and lower molds to manually spray the surface of the cavity. This method has significant technical shortcomings. The forging station is in a high-temperature and high-dust environment for a long time. The oil fumes and heat radiation generated by the high-temperature atomization of the release agent can easily cause occupational health damage to the operators. In addition, manual operation is labor-intensive and has low production efficiency. The spray thickness and coverage are highly dependent on the operator's experience, resulting in poor batch consistency and the problem of local missed spraying or excessive accumulation of release agent. Missed areas will cause scratches and adhesion on the surface of the copper pipe fittings, while excessive release agent will form carbon deposits and pits on the surface of the forging, directly affecting the product qualification rate.

[0004] Therefore, a forging copper pipe forming device is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a forging copper pipe forming apparatus, which aims to solve the problems pointed out in the background art.

[0006] The present invention provides a forging copper pipe forming apparatus, comprising a forming machine body, and further comprising: The lifting seat is set on the main body of the molding machine. The upper mold is installed on the lifting seat, and the lower mold is set below the upper mold. The movable plate is located on one side of the molding machine body and can move along the length of the molding machine body. The movable plate is equipped with two sets of movable frame assemblies, and each set of movable frame assemblies is connected to a nozzle. The movable frame assemblies are used to adjust the position and height of the movable plate. The infusion assembly is installed on the main body of the molding machine and is connected to the nozzle to deliver the release agent to the nozzle; The linkage structure connects the movable plate and the lifting seat, and is used to make the movable plate move synchronously with the movement of the lifting seat.

[0007] Preferably, the linkage structure includes a linear module, a slide block, a guide rod, a connecting rod, a sliding seat, and a guide rail. The linear module is mounted on the main body of the molding machine, the slide block is set on the linear module, there are two guide rods, the guide rods are fixedly mounted on the slide block, the guide rods pass through the moving plate and are slidably connected to the moving plate, the bottom end of the connecting rod is hinged to the top end of the moving plate, and the top end of the connecting rod is hinged to the sliding seat. The sliding seat has at least one sliding groove, and the lifting seat is equipped with at least one guide rail. The length direction of the guide rail is parallel to the length direction of the main body of the molding machine. The guide rail and the sliding groove are both T-shaped, and the sliding seat is slidably connected to the guide rail through the sliding groove.

[0008] Preferably, the movable frame assembly includes a movable frame, a locking threaded rod, and a locking nut. The movable frame is slidably sleeved on the movable plate, and a limiting groove is provided on the movable plate. The locking threaded rod is fixedly connected to one side of the movable frame and passes through the inside of the limiting groove. The locking threaded rod is slidably connected to the limiting groove, and the locking nut is threadedly connected to the outer surface of the locking threaded rod.

[0009] Preferably, the mobile frame assembly further includes a storage frame, an extension rod, a mounting block, and a locking structure. The storage frame is fixedly connected to one side of the mobile frame, the extension rod is slidably disposed inside the storage frame, the mounting block is fixedly connected to the end of the extension rod, the nozzle is mounted on the mounting block, and the locking structure is disposed between the extension rod and the storage frame, and the locking structure is used to lock the position of the extension rod.

[0010] Preferably, the locking structure includes a limiting through groove, a second locking threaded rod, a second locking nut, and a support rod. The limiting through groove is opened on one side of the storage frame and is connected to the interior of the storage frame. The second locking threaded rod is installed on one side of the extension rod and passes through the interior of the limiting through groove and is slidably connected to the limiting through groove. The second locking nut is threadedly connected to the outer surface of the second locking threaded rod. The support rod is installed inside the storage frame, and a support hole is opened on one side of the extension rod. The support rod is located inside the support hole and is slidably connected to the support hole.

[0011] Preferably, the infusion assembly includes a support base, a material tank, a delivery pump, and a three-way pipe. The support base is installed on one side of the molding machine body, the material tank is set on the support base, the material tank is connected to the inlet of the delivery pump through a pipe, the outlet of the delivery pump is connected to the three-way pipe, and the three-way pipe is connected to two nozzles respectively through a material delivery hose.

[0012] Preferably, a drive unit is installed on the material barrel, and the output end of the drive unit is connected to a stirring rod. The drive unit is used to drive the stirring rod to rotate, and the stirring rod is located inside the material barrel.

[0013] The beneficial effects of this invention are: 1. The linkage structure mechanically links the mold opening action of the lifting seat with the spraying feed action of the moving plate. After the forging mold is opened, the spray head can automatically enter the upper and lower mold parting area to complete the spraying operation, completely replacing the traditional manual spraying mode of holding a spray gun. It eliminates the need for operators to be in close contact with the high-temperature forging station, fundamentally avoiding the occupational health damage to operators caused by high-temperature heat radiation, mold release agent atomized fumes and metal dust, and significantly reducing the labor intensity of the job. At the same time, the automated spraying can be seamlessly connected with the forging process, saving the redundant time of manual entry, alignment and exit, effectively compressing the production cycle of a single workpiece, and greatly improving the single-station capacity and production continuity of copper pipe forging.

[0014] 2. This device adopts a dual-nozzle directional arrangement structure, combined with precise displacement control of the linkage structure. After the mold is opened, the nozzles can be accurately aligned with the cavity surfaces of the upper and lower molds. The spraying distance, spraying angle, and spraying time can all be stably controlled, completely eliminating the problems of uneven coating thickness, local missed spraying, or excessive accumulation of release agent caused by differences in operating experience in manual spraying. The uniform and complete release agent coating can effectively avoid surface scratches and film defects of forgings, while eliminating the problem of surface carbon deposits and pitting caused by excessive release agent thickness, significantly improving the surface quality and batch pass rate of copper pipe forgings.

[0015] 3. The horizontal reference position of the spraying station can be adjusted as a whole through the linear module and the slide block. The height position of the nozzle can be adjusted through the cooperation of the moving frame and the limiting slide groove. The horizontal extension depth of the nozzle can be adjusted through the telescopic cooperation of the extension rod and the storage frame. Thus, the device can be adapted to a variety of forging dies with different parting surface heights, cavity depths and outer dimensions, and can meet the forging and spraying needs of copper pipe fittings of various specifications. When changing products, there is no need to change the special spraying tooling. Only the locking structure needs to be adjusted to quickly complete the parameter adaptation, effectively reducing the tooling cost and changeover time for multi-variety production.

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 9 As shown, a forging copper pipe forming device of the present invention includes a forming machine body 10, a lifting seat 11 is provided on the forming machine body 10, an upper die 12 is provided on the lifting seat 11, and a lower die 13 is provided below the upper die 12, with the upper die 12 and the lower die 13 corresponding in position. The upper die 12 moves along the height direction of the forming machine body 10. The forming machine body 10 is provided with a structure that drives the lifting seat 11 to move up and down. Since its working principle and structure are existing mature technologies, they are not described in detail. A moving plate 20 is provided on one side of the forming machine body 10. The moving plate 20 moves along the forming machine body... The main body 10 moves along its length, and the height of the moving plate 20 is parallel to the height of the main body 10. Two sets of moving frame assemblies are provided on the moving plate 20, and each set of moving frame assemblies is connected to a nozzle 21. The moving frame assemblies are used to adjust the position and height of the moving plate 20. A liquid delivery assembly is provided on the main body 10 of the molding machine. The liquid delivery assembly is connected to the nozzle 21. The liquid delivery assembly is used to deliver the release agent into the interior of the nozzle 21. A linkage structure is provided between the moving plate 20 and the lifting seat 11. The linkage structure is used to make the moving plate 20 move synchronously with the movement of the lifting seat 11.

[0028] After the copper pipe forging process is completed, the lifting seat 11 drives the upper mold 12 to start moving upward to open the mold. The linkage structure synchronously converts the upward displacement of the upper mold 12 into the horizontal feed displacement of the moving plate 20, so that the nozzle 21 gradually enters the parting space between the upper and lower molds as the mold opening gap widens. When the upper mold 12 rises to the maximum mold opening stroke, the two nozzles 21 are precisely aligned with the lower cavity surface of the upper mold 12 and the upper cavity surface of the lower mold 13, respectively. At this time, the liquid delivery component is activated, pressurizing and delivering the release agent into the nozzle 21 and atomizing it for spraying. The upward nozzle 21 completes the spraying of the upper mold 12 cavity, and the downward nozzle 21 completes the spraying of the lower mold 13 cavity. The spraying feed action and the mold opening action are carried out synchronously, without waiting for the mold opening to be completely finished before starting the spraying, effectively compressing the single-cycle production cycle and improving production efficiency.

[0029] The linkage structure includes a linear module 14 installed on the molding machine body 10. A slide block 15 is provided on the linear module 14. The linear module 14 drives the slide block 15 to move along the length direction of the molding machine body 10. Two guide rods 16 are fixedly installed on the slide block 15. The guide rods 16 pass through the moving plate 20. The moving plate 20 is slidably connected to the guide rods 16. A connecting rod 22 is hinged to the top of the moving plate 20. A sliding seat 23 is hinged to the top of the connecting rod 22. At least one sliding groove is provided on the sliding seat 23. At least one guide rail 17 is installed on the lifting seat 11. The length direction of the guide rail 17 is parallel to the length direction of the molding machine body 10. The guide rail 17 and the sliding groove are both T-shaped. The sliding seat 23 is slidably connected to the guide rail 17 through the sliding groove.

[0030] By adjusting the position of the slide block 15 on the linear module 14, the horizontal reference of the spraying station can be adjusted as a whole. When the lifting seat 11 rises, the guide rail 17 moves upward synchronously with the lifting seat 11. The sliding seat 23 slides along the guide rail 17 away from the mold area. At the same time, the connecting rod 22 pulls the moving plate 20 up along the guide rod 16 and moves horizontally towards the mold area, realizing the conversion of lifting motion into horizontal feeding motion.

[0031] The movable frame assembly includes a limiting groove 201 formed on the movable plate 20. A locking threaded rod 30 is slidably disposed inside the limiting groove 201. A locking nut 31 is threadedly connected to the outer surface of the locking threaded rod 30. A movable frame 32 is fixedly connected to the end of the locking threaded rod 30. A part of the movable plate 20 is located inside the movable frame 32. The movable frame 32 is slidably connected to the movable plate 20. A U-shaped storage frame 33 is fixedly connected to the side of the movable frame 32 away from the locking threaded rod 30. An extension rod 34 is slidably disposed inside the storage frame 33. A mounting block 35 is fixedly connected to the end of the extension rod 34. The nozzle 21 is mounted on the mounting block 35. A locking structure is provided between the extension rod 34 and the storage frame 33. The locking structure is used to lock the position of the extension rod 34.

[0032] The locking structure includes a limiting groove 331 on one side of the storage frame 33, which is connected to the interior of the storage frame 33. A locking threaded rod 36 is fixedly connected to one side of the extension rod 34. The locking threaded rod 36 passes through the interior of the limiting groove 331 and is slidably connected to the limiting groove 331. A locking nut 37 is threadedly connected to the outer surface of the locking threaded rod 36. A support rod 38 is fixedly connected to the interior of the storage frame 33. A support hole is opened on one side of the extension rod 34. The support rod 38 is located inside the support hole and is slidably connected to the support hole.

[0033] When adjusting the position of the moving frame 32, the moving frame 32 slides up and down along the height direction of the moving plate 20. The locking threaded rod 30 slides synchronously along the limiting slide groove 201 with the moving frame 32. At this time, the nozzle 21 moves synchronously. Adjust the nozzle 21 to a suitable height, and then tighten the locking nut 31 so that the locking nut 31 is close to the side wall of the moving plate 20. The moving frame 32 is fixed at the target height position by friction, thereby realizing the height adjustment operation of the nozzle 21. The extension rod 34 slides horizontally along the inner cavity of the storage frame 33. Adjust the extension depth of the nozzle 21 into the mold area. During this process, the locking thread rod 36 slides synchronously along the limiting groove 331. The limiting groove 331 plays a circumferential limiting role on the locking thread rod 36, preventing the extension rod 34 from rotating inside the storage frame 33. After adjusting the extension rod 34 to the target extension length, tighten the locking nut 37 so that the end face of the locking nut 37 is in close contact with the outer wall of the storage frame 33. The friction force generated by the pressure locks the relative position of the extension rod 34 and the storage frame 33, thus completing the limiting operation of the nozzle 21.

[0034] The infusion assembly includes a support base 40 installed on one side of the molding machine body 10. A material tank 41 is fixedly installed on one side of the support base 40. The material tank 41 is connected to a delivery pump 42 through a pipe. A three-way pipe 43 is connected to the outlet of the delivery pump 42 through a pipe. The other two connection ports of the three-way pipe 43 are fixedly connected to material delivery hoses 44. The end of the material delivery hose 44 away from the three-way pipe 43 is connected to the nozzle 21 and they correspond one-to-one.

[0035] After the delivery pump 42 is started, the release agent in the material tank 41 is pressurized and extracted, and sent into the three-way pipe 43 through the delivery pipeline. The three-way pipe 43 evenly divides the single high-pressure release agent into two streams, which are delivered to the corresponding two nozzles 21 through two material delivery hoses 44, and sprayed out through the nozzles 21, thereby performing the operation of spraying release agent.

[0036] A drive unit 45 is installed on the material barrel 41. The output end of the drive unit 45 is connected to a stirring rod 46. The drive unit 45 is used to drive the stirring rod 46 to rotate. The stirring rod 46 is located inside the material barrel 41 and is used to stir the inside of the material barrel 41 to prevent the release agent from solidifying.
