Description

Technical Field

[0001] This utility model relates to profile shaping equipment, and in particular to an online liquid-cooled constant temperature thin-walled profile shaping device. Background Technology

[0002] Currently, with the continuous development of technology, thin-walled cavity profiles are being used more and more widely in fields such as automotive water-cooled plates. However, in the production process of thin-walled profiles, their thin wall thickness, long cantilever, complex cross-section, tight tolerance, and twisting problems seriously affect the quality of the product. Therefore, thin-walled profiles need to be shaped after extrusion. Conventional shaping usually uses manual shaping, mechanical rolling, etc., and it is a downstream process, which is not only inefficient but also difficult to guarantee the quality. There is also a patented online shaping tooling, but it relies on simple hydraulic and mechanical devices. The profile temperature is high, and long-term operation will cause the tooling temperature to rise, making it difficult to guarantee the tolerance. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide an online liquid-cooled constant-temperature thin-walled profile shaping device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an online liquid-cooled constant temperature thin-walled profile shaping device, including a base, uprights disposed at both ends of the base, a lower shaping roller and an upper shaping roller disposed between the uprights, the upper shaping roller and the lower shaping roller being arranged in parallel, the upper shaping roller and the lower shaping roller forming a straight line to form a shaping gap, the upper shaping roller and the lower shaping roller having the same structure, the upper shaping roller including a hollow shaft, a shaping roller sleeve disposed on the hollow shaft, a water collection tray disposed on the hollow shaft, and a forming gap disposed on the forming roller. The hollow shaft includes a return water pipe, a water inlet connector at one end of the hollow shaft, and a return water connector at the other end of the hollow shaft. A lower bearing seat rotatably connects to the lower shaping roller on the upright frame, and an upper bearing seat rotatably connects to the upper shaping roller on the upright frame. The water collection tray has a return water cavity, and a return water hole communicating with the return water cavity is provided on the surface of the water collection tray. The return water cavity communicates with the return water pipe. The water collection trays are arranged along the axial direction of the hollow shaft, and a water inlet hole penetrating the hollow shaft is provided on the hollow shaft between the water collection trays.

[0005] As a further improvement to this design, the upright frame is provided with a vertical slide rail, the upper bearing seat is slidably engaged with the vertical slide rail, an adjusting screw is rotatably connected to the upper bearing seat, a nut seat is provided at the top of the upright frame, an adjusting nut is provided on the nut seat to engage with the adjusting screw, and a locking nut is threaded onto the adjusting screw.

[0006] As a further improvement to this design, each of the upper bearing seats is slidably engaged with the two vertical slide rails, which are arranged opposite each other.

[0007] As a further improvement to this design, the outer periphery of the water collection tray is connected to the inner wall of the shaping roller sleeve, that is, the water collection tray divides the inner cavity of the shaping roller sleeve into multiple chambers. The water inlet is equipped with a spray head, and the water return hole is located at the outer edge on both sides of the water collection tray. The spray direction of the spray head is towards the inner wall of the shaping roller sleeve. The water return connector is connected to the negative pressure return port of the circulating cooling system, and the water inlet connector is connected to the high pressure outlet of the circulating cooling system.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0018] Example: An online liquid-cooled constant-temperature thin-walled profile shaping device includes a base 1, uprights 2 disposed at both ends of the base 1, a lower shaping roller 10 and an upper shaping roller 3 disposed between the uprights 2, the upper shaping roller 3 and the lower shaping roller 10 being arranged in parallel, the upper shaping roller 3 and the lower shaping roller 10 forming a straight forming gap 15, the upper shaping roller 3 and the lower shaping roller 10 having the same structure, the upper shaping roller 3 including a hollow shaft 30, a shaping roller sleeve 33 disposed on the hollow shaft 30, a water collection tray 31 disposed on the hollow shaft 30, a return water pipe 34 disposed inside the hollow shaft 30, and a water collection tray 31 disposed on the hollow shaft 30. The hollow shaft 30 has an inlet connector 14 at one end and a return connector 13 at the other end. The support frame 2 is provided with a lower bearing seat 8 that is rotatably connected to the lower shaping roller 10. The support frame 2 is provided with an upper bearing seat 7 that is rotatably connected to the upper shaping roller 3. The water collection tray 31 is provided with a return water cavity 35. The surface of the water collection tray 31 is provided with a return water hole 32 that communicates with the return water cavity 35. The return water cavity 35 communicates with the return water pipe 34. The water collection trays 31 are arranged along the axial direction of the hollow shaft 30. The hollow shaft 30 between the water collection trays 31 is provided with an inlet hole 36 that penetrates the hollow shaft 30.

[0019] The upper forming roller 3 and the lower forming roller 10 are configured as hollow rollers and connected to the circulating cooling system, so that the upper forming roller 3 and the lower forming roller 10 are kept at a constant temperature throughout the forming process. This prevents the upper forming roller 3 and the lower forming roller 10 from expanding after heating up, which would lead to a decrease in forming accuracy. This makes it easy to directly connect to the profile extrusion production line and reduce the number of processes. The design of the water collection tray 31 and the hollow shaft 30 ensures that the temperature of the forming roller sleeve 33 is uniform and prevents deformation caused by uneven temperature.

[0020] To accommodate products of varying thicknesses and facilitate adjustment, the upright frame 2 is equipped with a vertical slide rail 6. The upper bearing seat 7 is slidably engaged with the vertical slide rail 6. An adjusting screw 9 is rotatably connected to the upper bearing seat 7. A nut seat 5 is located at the top of the upright frame 2, and an adjusting nut 4 engages with the adjusting screw 9. A locking nut 12 is threaded onto the adjusting screw 9. The top of the locking nut 12 abuts against the nut seat 5, ensuring the stability of the shaping gap 15.

[0021] In order to counteract the lateral force in the front-back direction of the upper shaping roller 3, each of the upper bearing seats 7 is slidably engaged with the two vertical slide rails 6, which are arranged opposite each other.

[0022] To reduce water consumption, reduce roller weight, improve water utilization, and reduce energy consumption, the outer periphery of the water collection tray 31 is connected to the inner wall of the shaping roller sleeve 33. That is, the water collection tray 31 divides the inner cavity of the shaping roller sleeve 33 into multiple chambers. The water inlet 36 is equipped with a spray head 37, and the water return holes 32 are located at the outer edges on both sides of the water collection tray 31. The spray direction of the spray head 37 is towards the inner wall of the shaping roller sleeve 33. The water return connector 13 is connected to the negative pressure return port of the circulating cooling system, and the water inlet connector 14 is connected to the high-pressure outlet of the circulating cooling system. The use of spray cooling reduces the load on the circulating cooling system pump. The circulating cooling system uses a commercially available constant temperature water cooling system, and both the water inlet connector 14 and the water return connector 13 are commercially available connectors.

[0023] To improve the stability of the uprights 2, a reinforcing rod 11 is connected between the top and bottom of the two uprights 2. Example

[0024] The difference between this embodiment and Embodiment 1 is that the outer periphery of the water collecting tray 31 is not connected to the inner wall of the shaping roller sleeve 33, the return water hole 32 is disposed on the outer periphery of the water collecting tray 31, the water inlet connector 14 is connected to the high-pressure outlet of the circulating cooling system, and the return water connector 13 is connected to the return outlet of the circulating cooling system. For profiles with a large amount of high-heat material, the above structure has a better cooling effect.

[0025] During operation, open the locking nut 12, rotate the adjusting screw 9 to adjust the height of the upper shaping roller 3, and then adjust the shaping gap 15 and appropriate width. Close the locking nut 12. The circulating cooling system injects coolant into the upper shaping roller 3 and the lower shaping roller 10. The coolant enters the inner cavity of the shaping roller sleeve 33 through the water inlet 36 on the hollow shaft 30. After cooling the shaping roller sleeve 33, the coolant enters the water collection tray 31 and flows back into the circulating cooling system.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
