Abstract

This application relates to the field of electric heating tube processing technology and discloses a bending mechanism for irregularly shaped electric heating tubes, including a worktable, a turntable rotatably connected to the top of the worktable, a limit plate fixedly connected to the top of the turntable, a pressing mechanism inserted into the top of the worktable, and a driving mechanism rotatably connected inside the turntable. This bending mechanism for irregularly shaped electric heating tubes uses a second screw that penetrates the interior of a support base. When bending electric heating tubes of different specifications is required, rotating the second screw drives the support base to move longitudinally, increasing its inner limiting width. This, in conjunction with the driving mechanism, drives the longitudinal screw to rotate, providing displacement driving force for the limit post.

Description

Technical Field

[0001] This utility model belongs to the field of electric heating tube processing technology, and in particular relates to a bending mechanism for irregularly shaped electric heating tubes. Background Technology

[0002] A tubular heating element is an electrical component specifically designed to convert electrical energy into heat energy. It consists of a metal tube as its outer shell, with spiral heating alloy wires evenly distributed along the central axis inside the tube. The gaps are filled with compacted magnesium oxide sand, which has excellent insulation and thermal conductivity. Both ends of the tube are sealed with silicone. This metal-clad heating element can heat air, metal molds, and various liquids.

[0003] An existing patent (publication number: CN219004194U) discloses a heating element bending machine for a heater, which relates to the technical field of heating element processing equipment. It includes a fixed base, and hydraulic lifting rods are provided at the four corners of the top of the fixed base. An operating platform is provided on the top of the hydraulic lifting rods, and a fixing mechanism is provided on the left side of the top of the operating platform. When facing a heating element that is larger than the heating element placement slot, the heating element can be directly fixed by the threaded fixing rod.

[0004] Currently, electric heating tube bending machines typically require manual assistance during the bending process. However, existing bending equipment is not convenient for bending electric heating tubes of different sizes. In particular, when it is necessary to continuously bend irregularly shaped electric heating tubes, changing to different bending equipment of different sizes delays work efficiency and increases operating costs. Therefore, an irregularly shaped electric heating tube bending mechanism is proposed to solve the above problems. Summary of the Invention

[0005] Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this application provides a bending mechanism for irregularly shaped electric heating tubes. This mechanism offers advantages such as providing different bending limit gaps for electric heating tubes of different specifications, eliminating the need for manual replacement of bending equipment, and improving bending efficiency. It solves the problem mentioned in the aforementioned prior art where changing bending equipment of different sizes delays work efficiency and increases operating costs when continuous bending of irregularly shaped electric heating tubes is required.

[0007] To achieve the above objectives, this application provides the following technical solution: a bending mechanism for irregularly shaped electric heating tubes, comprising a worktable, a turntable rotatably connected to the top of the worktable, a limit plate fixedly connected to the top of the turntable, a pressing mechanism inserted into the top of the worktable, a driving mechanism rotatably connected inside the turntable, a longitudinal screw meshing on one side of the driving mechanism, a limit post threadedly connected to the outer surface of the longitudinal screw, a support seat slidably connected to the inner wall of the pressing mechanism, and a second screw threadedly connected to the inner surface of the support seat.

[0008] With the above solution, the second screw passes through the interior of the support base. When bending electric heating tubes of different specifications is required, rotating the second screw can drive the support base to move longitudinally to increase its inner limiting width. In conjunction with the drive mechanism, the longitudinal screw is driven to rotate, providing displacement driving force for the limiting post. This allows the post to follow the displacement of the support base at the rear end of the electric heating tube to adjust the gap between it and the limiting plate. This provides different bending limiting gaps for electric heating tubes of different specifications, eliminating the need for manual replacement of bending equipment and improving bending efficiency.

[0009] Furthermore, the extrusion mechanism includes an extrusion disc, an arc-shaped plate is fixedly installed on the top of the extrusion disc, a slide is fixedly installed on the bottom of the extrusion disc, and the support is slidably connected to the inner wall of the slide.

[0010] The above scheme involves setting an arc-shaped plate on the top of the extrusion plate. With the cooperation of the limiting post and the limiting plate, when the turntable is rotated, the limiting post and the limiting plate move and rotate according to the rotation angle. Together with the arc-shaped plate, they form an extrusion cavity for the heating tube. This causes the bending position of the heating tube to be squeezed and pushed by the arc-shaped plate, which, together with the limiting post and other components, forms a bending angle on the heating tube, so that the heating tube can be bent quickly.

[0011] Furthermore, the driving mechanism includes a driving handle, a worm gear is fixedly mounted on the bottom of the driving handle, and a worm wheel is fixedly mounted on the outer surface of the longitudinal screw, with the worm gear meshing with the worm wheel.

[0012] The above scheme uses a rotating drive handle to drive the worm gear to rotate, which in turn drives the worm wheel outside the longitudinal screw to rotate, thereby driving the longitudinal screw to rotate and providing displacement driving force for the limit post.

[0013] Furthermore, a threaded slider is fixedly installed at the bottom of the limiting post, and a sliding sleeve is fixedly connected to the outer surface of the limiting post. The longitudinal screw passes through the outside of the threaded slider and is threadedly connected to it.

[0014] With the above scheme, by setting the threaded slider, when the longitudinal screw rotates, it drives the threaded slider to move in the opposite direction along its longitudinal direction, while the upper sliding sleeve moves along the outside of the limiting plate. After moving to the appropriate position, it stops, so that the sliding sleeve is always supported between the limiting plate and the limiting post, providing support for the bending of the heating tube. In addition, this combination can provide bending gaps for heating tubes of different diameters, which is convenient for providing bending processing effects for heating tubes of various diameters.

[0015] Furthermore, a limiting slider is fixedly installed at the bottom of the support base, and an inner groove is provided on the inner wall of the slider base, with the limiting slider slidably connected to the inside of the inner groove.

[0016] With the above scheme, the limiting slider and the second screw work together to drive the support seat to move along the inner wall of the slide when the second screw is rotated. The limiting slider at the bottom slides inside the inner groove to limit the movement of the support seat, so that the distance between the support seat and the arc plate can be changed according to the specifications of the heating tube, so as to increase or decrease the bending gap to adapt to different heating tubes.

[0017] Furthermore, the top of the turntable has an embedded groove, and the longitudinal screw is located inside the embedded groove.

[0018] The above solution provides limiting space for the longitudinal screw and the threaded slider through the embedded groove, allowing the threaded slider to move smoothly without obstructing other components on the turntable 2.

[0019] Furthermore, a fixing block is fixedly installed on the top of the turntable, and a rotating rod is threadedly connected to the inner wall of the fixing block.

[0020] The above scheme uses a fixing block and bolts to fix the rotating rod to the turntable. The operator can indirectly drive the turntable to rotate by pushing the rotating rod, so that the top limiting post and limiting plate can rotate together at a certain angle. This facilitates the operator to rotate the turntable and bend the heating element.

[0021] Furthermore, a torsion spring is fixedly installed at the bottom of the extrusion disc.

[0022] The above solution uses a torsion spring to elastically restrict the bottom of the extrusion plate, allowing the extrusion plate to rotate slightly following the bending path of the heating element and automatically reset.

[0023] Beneficial effects

[0024] This non-standard electric heating tube bending mechanism uses a second screw that passes through the interior of the support base. When bending electric heating tubes of different specifications is required, rotating the second screw drives the support base to move longitudinally, increasing its inner limiting width. In conjunction with the drive mechanism, the longitudinal screw is rotated to provide displacement driving force for the limiting post, allowing it to adjust the gap between the limiting post and the rear support base of the electric heating tube according to the displacement. This provides different bending limiting gaps for electric heating tubes of different specifications, eliminating the need for manual replacement of bending equipment and improving bending efficiency.

[0031] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a bending mechanism for irregularly shaped electric heating tubes includes a workbench 1, a turntable 2 rotatably connected to the top of the workbench 1, a limiting plate 3 fixedly connected to the top of the turntable 2, a pressing mechanism 4 inserted into the top of the workbench 1, a driving mechanism 5 rotatably connected inside the turntable 2, a longitudinal screw 6 meshing with one side of the driving mechanism 5, a limiting post 7 threadedly connected to the outer surface of the longitudinal screw 6, a support seat 8 slidably connected to the inner wall of the pressing mechanism 4, and a second screw 9 threadedly connected to the inside of the support seat 8. The second screw 9 penetrates the interior of the support seat 8. When bending electric heating tubes of different specifications is required, rotating the second screw 9 drives the support seat 8 to move longitudinally, increasing its inner limiting width. This, combined with the driving mechanism 5 driving the longitudinal screw 6 to rotate, provides displacement driving force for the limiting post 7, allowing it to adjust the gap between the support seat 8 at the rear end of the electric heating tube and the limiting plate 3. This provides different bending limiting gaps for electric heating tubes of different specifications, eliminating the need for manual replacement of bending equipment and improving bending efficiency.

[0033] Please see Figure 2 and Figure 5The extrusion mechanism 4 includes an extrusion plate 401, an arc-shaped plate 402 fixedly mounted on the top of the extrusion plate 401, and a slide block 403 fixedly mounted on the bottom of the extrusion plate 401. The support base 8 is slidably connected to the inner wall of the slide block 403. By setting the arc-shaped plate 402 on the top of the extrusion plate 401, and through the cooperation of the limiting post 7 and the limiting plate 3, when the turntable 2 is rotated, the limiting post 7 and the limiting plate 3 move and rotate according to the rotation angle, and cooperate with the arc-shaped plate 402 to form an extrusion cavity for the heating tube, so that the bending position of the heating tube is curved. The plate extrusion pushes and, together with the limiting post 7 and other components, forms a bending angle on the heating element, so that the heating element is quickly bent. The driving mechanism 5 includes a driving handle 501, a worm 502 is fixedly installed at the bottom of the driving handle 501, and a worm wheel 601 is fixedly installed on the outer surface of the longitudinal screw 6. The worm 502 meshes with the worm wheel 601. By rotating the driving handle 501, the worm 502 is driven to rotate, thereby driving the worm wheel 601 on the outside of the longitudinal screw 6 to rotate, thereby driving the longitudinal screw 6 to rotate, and providing displacement driving force for the limiting post 7.

[0034] Please see Figure 3 and Figure 4 A threaded slider 12 is fixedly installed at the bottom of the limiting post 7. A sliding sleeve 13 is fixedly connected to the outer surface of the limiting post 7. A longitudinal screw 6 passes through the outside of the threaded slider 12 and is threadedly connected to it. When the longitudinal screw 6 rotates, it drives the threaded slider 12 to move in the opposite direction along its longitudinal direction. At the same time, the upper sliding sleeve 13 moves along the outside of the limiting plate 3. After moving to the appropriate position, it stops, so that the sliding sleeve 13 is always supported between the limiting plate 3 and the limiting post 7, providing support for the bending of the heating tube. This combination can provide bending gaps for different diameter heating tubes, which is convenient for providing bending treatment effects for heating tubes of various diameters.

[0035] Please see Figure 1 and Figure 2 A limiting slider 16 is fixedly installed at the bottom of the support base 8. An inner groove 404 is provided on the inner wall of the slide base 403. The limiting slider 16 is slidably connected to the inside of the inner groove 404. Through the cooperation of the limiting slider 16 and the second screw 9, when the second screw 9 is rotated, the support base 8 is driven to move along the inner wall of the slide base 403, and the limiting slider 16 at the bottom slides inside the inner groove 404 to limit the movement of the support base 8, so that it can change the distance between the support base 8 and the arc plate 402 according to the specifications of the electric heating tube, so as to increase or decrease the bending gap to adapt to different electric heating tubes.

[0036] In this embodiment, a bending mechanism for irregularly shaped electric heating tubes is provided. By setting an arc-shaped plate 402 on the top of the extrusion plate 401, and cooperating with the limiting post 7 and the limiting plate 3, an extrusion cavity can be formed for the electric heating tube. By driving the rotating handle 501 and the worm gear 502 to drive the longitudinal screw 6 to rotate, it provides displacement driving force for the limiting post 7, making the distance between the limiting post 7 and the limiting plate 3 adjustable, providing bending gaps for electric heating tubes of different diameters. At the same time, the second screw 9 drives the support seat 8 to move in the same way, adjusting the distance between the adjuster itself and the arc-shaped plate 402 to provide corresponding support gaps for the rear end of the electric heating tube. This facilitates bending processing for electric heating tubes of various diameters without the need for manual replacement of bending equipment, improving bending efficiency. The rotating rod 15 is fixed on the turntable 2 by the fixing block 10 and bolts, which facilitates the operator to rotate the turntable 2 to perform bending operations on the electric heating tube.

[0037] The working principle of the above embodiments is as follows:

[0038] In use, rotating the drive handle 501 drives the worm gear 502 to rotate, which in turn drives the worm wheel 601 outside the longitudinal screw 6 to rotate. This causes the longitudinal screw 6 to rotate and drives the threaded slider 12 to move in the opposite direction along its longitudinal direction. At the same time, the upper sliding sleeve 13 moves along the outside of the limiting plate 3 and stops after moving to the appropriate position. When the second screw 9 is rotated, the support seat 8 moves along the inner wall of the slide 403 and slides inside the inner slide groove 404 in conjunction with the bottom limiting slider 16. This causes the support seat 8 to move to the same distance as the limiting post 7 and then stop. The drive rod 15 is pushed to drive the turntable 2 to rotate. At the same time, the angle between the limiting post 7 and the limiting plate 3, together with the arc plate 402, forms a compression cavity for the heating tube, causing the heating tube located inside the support seat 8 to be bent.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application.
