Description

Technical Field

[0001] This utility model relates to the technical field of coiling and pressing devices, specifically a copper tube rolling coiling and pressing device. Background Technology

[0002] The copper tube rolling coiling and pressing device is an auxiliary device used in the copper tube rolling process. Its main function is to press the coiled copper tube during the rolling process to ensure the smooth progress of the copper tube coiling process and the quality of the product, reduce the warping state of the copper tube coiling, and improve the tightness and stability of the copper tube coiling.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN211920280U) discloses a copper alloy tube winding and pressing device, comprising a support sleeve, an adjusting sleeve on the upper part of the support sleeve, and a bearing column within the adjusting sleeve; the bearing column is fixedly secured by multiple adjusting studs on its side wall; a bearing plate is fixedly mounted on the top of the bearing column, an electric push rod is mounted on the upper left side of the bearing plate, a push rod is provided at the right end of the electric push rod, and a fixed mounting plate is fixedly connected to the right end of the push rod; a first rotating rod and a second rotating rod are threaded on the left and right sides of the fixed mounting plate, respectively; an adjusting groove is provided on the right side of the bearing plate; the lower parts of the first rotating rod and the second rotating rod pass through the adjusting groove; the lower parts of the first rotating rod and the second rotating rod are threadedly connected to the first mounting plate and the second mounting plate, respectively. This utility model device, by employing an adjustable pressing device, can effectively press the copper alloy tube that needs to be wound, allowing it to be wound more effectively.

[0004] The aforementioned patent uses an adjustable pusher roller to assist in pushing the winding copper tube. However, since the contact between the pusher roller and the copper tube is a rigid rolling contact, when the copper tube bounces locally during the winding process, the copper tube tilts upward and generates a large contact force with the pusher roller. Since the pusher roller cannot achieve elastic adaptation with the copper tube, the contact surface between the bouncing copper tube and the pusher roller is subjected to excessive pressure deformation, which affects the winding quality of the copper tube.

[0005] Therefore, this utility model provides a copper tube rolling, coiling, and pressing device to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this application are as follows:

[0019] 1. This utility model uses a spring to make the pressure roller and the copper tube make elastic rolling contact. When the copper tube bounces severely in some areas during the winding process, it will drive the pressure roller to rise, so as to avoid the copper tube being deformed due to excessive pressure when the two are in contact, thereby improving the winding quality of the copper tube. At the same time, the arc-shaped structure of the pressure roller makes the copper tube fit into the interior of the arc-shaped structure, preventing the copper tube from shifting and falling off.

[0020] 2. This utility model, through the setting of the tensioning component, can assist in pulling the horizontal plate, thereby transferring the upward contact force between the push roller and the copper tube to the tensioning component, improving the load effect of the device while ensuring its static stability, and avoiding tilting due to long-term load, which would affect its pushing efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-5As shown, this utility model provides a copper tube rolling and coiling pushing device, including a hydraulic cylinder 1, with a horizontal plate 2 fixedly connected to the lifting end of the hydraulic cylinder 1; and a pushing assembly 3, which includes a second cylinder 31, fixedly connected to the upper surface of the horizontal plate 2, with a sliding plate 32 fixedly connected to the lifting end of the second cylinder 31. The sliding plate 32 is slidably disposed above the horizontal plate 2, with two guide shafts 33 passing through the interior of the sliding plate 32. A connecting piece 34 is fixedly connected to the bottom of the guide shaft 33, and a pushing roller 35 is rotatably disposed between the two connecting pieces 34. A spring 36 is sleeved on the outside of the guide shaft 33, and a pressure plate 3 is threadedly connected to the top of the guide shaft 33. 7; Tensioning component 4, which is inclinedly distributed between hydraulic cylinder 1 and horizontal plate 2, and is used for auxiliary support of horizontal plate 2. The height of horizontal plate 2 is adjusted by lifting control of hydraulic cylinder 1, and the horizontal push of second cylinder 31 drives the push roller 35 to adjust the horizontal displacement through slide plate 32. This improves the adaptability of pushing pressure in the copper tube winding state. By contacting the upper surface of copper tube with push roller 35, the jumping of copper tube during collection is reduced, while ensuring the tension of copper tube winding. In addition, the elastic cooperation of spring 36 reduces excessive pushing pressure on copper tube when the local jumping of copper tube is serious through the elastic displacement of push roller 35.

[0030] Furthermore, two guide rails 21 are fixedly connected to the upper surface of the horizontal plate 2, and a slider 22 is slidably connected to the outside of the guide rails 21. A slide plate 32 is fixedly connected to the upper surface of the slider 22. A rectangular groove 23 is provided between the two guide rails 21 on the horizontal plate 2. Through the cooperation of the guide rails 21 and the slider 22, the guide rails 21 and the slider 22 are used to assist in guiding and limiting the horizontal sliding of the slide plate 32, thereby improving the stability and smoothness of the displacement of the slide plate 32.

[0031] Furthermore, the guide shaft 33 extends through the rectangular groove 23 to the bottom of the horizontal plate 2. The width of the rectangular groove 23 is not less than the diameter of the guide shaft 33. The maximum outer diameter of the pressure plate 37 is greater than the outer diameter of the spring 36. The outer surface of the push roller 35 has an arc-shaped structure. By setting the outer surface structure of the push roller 35, the copper tube can be abutted and limited, improving the stability of the copper tube push and reducing the occurrence of copper tube falling off.

[0032] Furthermore, the two ends of the spring 36 abut against the slide plate 32 and the pressure plate 37 respectively. A corrugated sleeve 38 is also fitted over the outside of the spring 36, and the two ends of the corrugated sleeve 38 are fixedly connected to the slide plate 32 and the pressure plate 37 respectively. The corrugated sleeve 38 is fitted to achieve safety protection for the spring 36.

[0033] Furthermore, the tensioning assembly 4 includes a sleeve 41, which is fitted onto the outer wall of the hydraulic cylinder 1. A hinge seat 42 is hinged to the outside of the sleeve 41, and an adjusting shaft 43 is fixedly connected to the other end of the hinge seat 42. A tensioning shaft 44 is fitted onto the outside of the adjusting shaft 43, and a positioning seat 46 is hinged to the other end of the tensioning shaft 44 through the hinge seat 42. The positioning seat 46 is fixedly connected to the lower surface of the horizontal plate 2. Adjusting holes are evenly distributed on the adjusting shaft 43, and positioning holes are distributed on the outer wall of the bottom end of the tensioning shaft 44. Bolts 45 pass through the positioning holes and the corresponding adjusting holes. Through this structure, auxiliary support for the horizontal plate 2 can be achieved, thereby increasing the load capacity of the horizontal plate 2 and allowing the upward force of the horizontal plate 2 to be transmitted to the tensioning assembly 4, thereby improving the overall stability of the device installation. At the same time, the length adjustment of the adjusting shaft 43 and the tensioning shaft 44 can be adapted to the height adjustment of the hydraulic cylinder 1.

[0034] Working principle: First, the bolt fastener 45 is loosened. Then, the hydraulic cylinder 1 is adjusted according to the pushing height of the copper tube. After the adjustment is completed, the adjusting shaft 43 and the tensioning shaft 44 are tightened and fixed by the bolt fastener 45. Finally, the slide plate 32 is horizontally displaced by the push of the second cylinder 31. When the push roller 35 pushes the copper tube, the tension of the copper tube during winding is ensured by the pushing and pressing treatment of the push roller 35.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
