Description

Technical Field

[0001] This utility model relates to the field of pipeline manufacturing technology, specifically to an integrated internal heating device for steel-plastic composite pipe molding. Background Technology

[0002] The integrated internal heating device for steel-plastic composite pipe molding is a specialized piece of equipment in the production of steel-plastic composite pipes. It is primarily used for heating operations during the pipe lamination process. Through internal heating, it promotes the fusion of the plastic layer and the steel pipe, enhancing the bonding strength of the composite interface and ensuring the overall corrosion resistance and structural stability of the pipeline. Designed specifically for the steel-plastic composite pipe lamination process, this device meets conventional production needs and is one of the key pieces of equipment for improving lamination quality.

[0003] However, this device is typically designed to be adapted to fixed workpiece parameters (such as pipe diameter and internal cavity dimensions), with the layout, power distribution, and range of the heating units all tightly bound to specific specifications. When faced with workpieces of different pipe diameters, wall thicknesses, or internal cavity structures, its heating uniformity, precise temperature control, and effectiveness significantly decrease. It is difficult to be compatible with multiple specifications without adjusting the equipment, resulting in poor adaptability and making it unsuitable for the production needs of diverse steel-plastic composite pipes. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated internal heating device for steel-plastic composite pipe molding, which solves the problem that the integrated internal heating device for steel-plastic composite pipe molding is not suitable for workpieces of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated internal heating device for steel-plastic composite pipe molding, comprising a base, a bracket fixedly connected to the upper end of the base, a mounting seat fixedly connected to the upper end of the bracket, a slider slidably connected inside the mounting seat, a connecting block fixedly connected to the side of the slider away from the mounting seat, the connecting block contacting the mounting seat, a heating block fixedly connected to the side of the connecting block away from the slider, a heating tube sleeved on the outer side of the heating block, a threaded rod rotatably connected inside the mounting seat, a knob fixedly connected to the upper end of the threaded rod, the knob contacting the mounting seat, and a limit mechanism provided on the base.

[0006] Preferably, the outer side of the threaded rod is provided with positive and negative threads, and the threaded rod is connected to the slider by threads. Through the design of the threaded rod, two sliders can be moved simultaneously.

[0007] Preferably, a retaining ring is fixedly connected to the outer side of the threaded rod, and the retaining ring contacts the inner wall of the mounting base. The retaining ring is designed to limit the movement of the threaded rod.

[0008] Preferably, the limiting mechanism includes a guide rod, which is slidably connected inside the base. A fixed frame is fixedly connected to the upper end of the guide rod, and a sliding rod is slidably connected inside the fixed frame. A top plate is fixedly connected to each side of the sliding rod that is close to each other, and the top plate contacts the fixed frame. A spring is provided on the outer side of the sliding rod, and a limiting plate is fixedly connected to the end of the sliding rod away from the top plate. The limiting plate contacts the fixed frame, and a support rod is fixedly connected to the lower end of the fixed frame. The support rod is slidably connected to the base, and a limiting block is rotatably connected inside the base. The limiting block is movably connected to the support rod, and a limiting sleeve is fixedly connected to the upper end of the limiting block. Through the design of the limiting mechanism, the pipeline can remain stable during processing.

[0009] Preferably, one end of the spring contacts the top plate, and the other end of the spring contacts the fixing frame. Through the design of the spring, the top plate can be driven to limit the pipe.

[0010] Preferably, a protrusion is fixedly connected to the outer side of the limiting block, and the protrusion is rotatably connected to the base. Through the design of the protrusion, the limiting block can be limited.

[0011] Preferably, the limiting sleeve contacts the base, the limiting sleeve contacts the fixing frame, and the limiting sleeve is threadedly connected to the support rod. The design of the limiting sleeve allows the position of the fixing frame to be adjusted.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes the cooperation of components such as a slider, threaded rod, and connecting block. Rotating the threaded rod drives the slider to move axially, and the slider, via the connecting block, moves the heating blocks, thereby flexibly adjusting the spacing between the heating blocks. This design allows for precise adjustment of the heating area according to the inner cavity dimensions of pipes of different specifications, ensuring a tight fit between the heating blocks and the inner wall of the pipe. This effectively solves the limitation of traditional internal heating devices being only suitable for single-specification workpieces, and improves the compatibility and applicability of the device to multi-specification steel-plastic composite pipes.

[0014] 2. This utility model uses a fixed frame, a top plate, and a spring to work together. The spring force drives the top plate to elastically press against the pipe, ensuring that the pipe is stable and does not shift during processing. At the same time, a support rod and a limiting sleeve structure are set up. By adjusting the height position of the support rod in the limiting sleeve, it can flexibly adapt to pipes of different diameters and heights, realize the synchronous adjustment of pipe positioning and device height, and improve the compatibility and processing stability of multi-specification steel-plastic composite pipes.

[0022] Please see Figure 2-4 The threaded rod 26 has positive and negative threads on its outer side. The threaded rod 26 is connected to the slider 22 by threads. The design of the threaded rod 26 can drive the two sliders 22 to move at the same time. A knob 28 is fixedly connected to the upper end of the threaded rod 26. The knob 28 contacts the mounting base 21. A retaining ring 27 is fixedly connected to the outer side of the threaded rod 26. The retaining ring 27 contacts the inner wall of the mounting base 21. The design of the retaining ring 27 can limit the threaded rod 26. A limit mechanism 3 is provided on the base 1.

[0023] Please see Figure 2-4The limiting mechanism 3 includes a guide rod 31. The guide rod 31 is slidably connected inside the base 1. A fixed frame 32 is fixedly connected to the upper end of the guide rod 31. A sliding rod 33 is slidably connected inside the fixed frame 32. A top plate 34 is fixedly connected to the side of the sliding rod 33 that is close to each other. The top plate 34 is in contact with the fixed frame 32. A spring 35 is provided on the outside of the sliding rod 33. One end of the spring 35 is in contact with the top plate 34, and the other end of the spring 35 is in contact with the fixed frame 32. Through the design of the spring 35, the top plate 34 can be driven to limit the pipe. A limiting plate 36 is fixedly connected to the end of the sliding rod 33 away from the top plate 34. The limiting plate 36 is in contact with the fixed frame 32. A support rod 37 is fixedly connected to the lower end of the fixed frame 32. The support rod 37 is slidably connected to the base 1. A limiting block 38 is rotatably connected inside the base 1.

[0024] Please see Figure 2-4 The limiting block 38 is movably connected to the support rod 37. A protrusion 39 is fixedly connected to the outer side of the limiting block 38. The protrusion 39 is rotatably connected to the base 1. The protrusion 39 can limit the limiting block 38. The upper end of the limiting block 38 is fixedly connected to the limiting sleeve 310.

The position of the fixing frame 32 can be adjusted by the limiting sleeve 310. The limiting mechanism 3 can keep the pipeline stable during processing.

[0025] The specific implementation process of this utility model is as follows: When in use, by rotating the knob 28, the knob 28 drives the threaded rod 26 and the slider 22 to make threaded movement, thereby causing the slider 22 to drive the heating block 24 to move through the connecting block 23. The spacing between the heating blocks 24 can be adjusted according to the specifications of the pipe, so that the heating block 24 can be used for pipes of different specifications.

[0026] By rotating the limiting sleeve 310, the limiting sleeve 310 and the support rod 37 undergo threaded movement, thereby moving the support rod 37 within the limiting sleeve 310. This causes the support rod 37 to move the fixing frame 32, thus adjusting the position of the fixing frame 32. By moving the two top plates 34 away from each other, the top plates 34 drive the sliding rod 33 to slide and connect with the fixing frame 32, and the top plates 34 compress the spring 35, placing the pipe between the two top plates 34. Then, by releasing the top plates 34, the elastic force of the spring 35 can cause the top plates 34 to limit the pipe, keeping the pipe stable during processing.
