Technical Field
[0001] The utility model relates to the technical field of PE pipe production, in particular to a PE pipe production expansion device. Background Art
[0002] PE pipe, full name polyethylene pipe, is a plastic pipe made of high-density polyethylene or low-density polyethylene. PE pipe needs to be expanded during production, so a expanding device is needed. The "expanding device for PE pipe production" disclosed in the publication number "CN218227846U" has solved the technical disadvantages that the expanding head cannot be replaced and the scope of application is low. However, in actual use, expanding devices with similar structures still have many defects. For example, the overall structure is relatively simple. Before the pipe is expanded, the PE pipe needs to be heated and softened with the help of external heating equipment, resulting in the device not having the function of automatically preheating the PE pipe, which will increase the processing steps when the device expands the PE pipe, and increase the time used by the device to expand the PE pipe, resulting in the device having a slow efficiency in expanding the PE pipe. For this reason, we have designed a expanding device for PE pipe production to solve the above problems. Utility Model Content

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-5 The utility model provides a technical solution: a flaring device for PE pipe production, comprising a mounting mechanism 1 and a limiting mechanism 3 and a flaring mechanism 2 assembled on the top of the mounting mechanism 1 and distributed frontally and rearwardly, the mounting mechanism 1 comprising a main seat body 101, an electric push rod 205 fixedly mounted on the back of the main seat body 101, the flaring mechanism 2 comprising an assembly plate 201 and a preheating ring 4, the assembly plate 201 being fixedly connected to the output end of the electric push rod 205, a flaring pipe 202 fixedly mounted on the front of the assembly plate 201, a preheating rod 203 fixedly mounted on the front of the flaring pipe 202, a plurality of groups of heating inner rings 204 fixedly mounted inside the preheating rod 203, a plurality of groups of heating outer rings 402 fixedly mounted inside the preheating ring 4, a heating plate 401 fixedly mounted on the inner wall of the preheating ring 4, the limiting mechanism 3 comprising two groups of mounting seats 301, cylinders 302 symmetrically mounted on the top and bottom inside the two groups of mounting seats 301, and limited seats 303 fixedly mounted on the output ends of the two groups of cylinders 302.
[0022] Based on the above-mentioned structural setting, the PE pipe production expansion device consists of a mounting mechanism 1, a limiting mechanism 3 and an expansion mechanism 2, wherein the mounting mechanism 1 is the overall mounting support mechanism of the device, the limiting mechanism 3 is the limiting and fixing mechanism of the PE pipe, and the expansion mechanism 2 is the expansion processing mechanism of the PE pipe. With the aid of the expansion mechanism 2, the PE pipe can be heated and softened before the expansion treatment. Specifically, during the working process, the main seat body 101 can install and fix the overall mechanism of the device during operation, and the two groups of mounting seats 301 are respectively fixedly mounted on both sides of the top of the main seat body 101. The cylinders 302 installed on the two groups of mounting seats 301 can extend to push the two groups of limiting seats 303 in opposite directions, so that the two groups of limiting seats 303 moving in opposite directions can clamp and fix the PE pipe to be expanded, thereby ensuring the stability of the device when expanding the PE pipe. The expanding pipe 202 is fixed by the assembly plate 2 01 and the electric push rod 205 are suspended above the main seat body 101. When the PE pipe enters the device, the preheating rod 203 on the front of the expanding tube 202 will be inserted into its expanding end. The heating inner ring 204 inside the preheating rod 203 can heat and soften the inner wall of the expanding end of the PE pipe, and when the PE pipe enters the device, the preheating ring 4 will be sleeved on its expanding end, so that the outer wall of the expanded PE pipe can be heated and softened by the cooperation of the heating outer ring 402 and the heating plate 401 inside the preheating ring 4. When the outer wall and the inner wall of the expanding end of the PE pipe are heated and softened, the electric push rod 205 pushes the expanding tube 202 by stretching, so that the heated and softened PE pipe can be expanded through the expanding tube 202, realizing the function of integrated heating and expanding of the PE pipe, reducing the process of expanding the PE pipe, and improving the efficiency of expanding the PE pipe.
[0023] Furthermore, a feed wheel 104 is rotatably mounted on the front side of the top of the main body 101, and a wheel groove 105 is provided on the outer wall of the feed wheel 104. The feed wheel 104 can provide rolling support for the PE pipe when it enters the device, and the wheel groove 105 can limit the PE pipe when it rotates on the feed wheel 104, thereby increasing the stability of the PE pipe when it enters the device.
[0024] Furthermore, a fixing seat 403 is fixedly mounted on the bottom of the preheating ring 4, and the fixing seat 403 is fixedly mounted on the top of the main body 101. The fixing seat 403 is fixedly mounted on the top of the main body 101, and the fixing seat 403 can be used to install and support the preheating ring 4, ensuring the stability of the preheating ring 4 during operation.
[0025] Furthermore, the inner walls of both sets of limit seats 303 are fixedly mounted with multiple sets of anti-skid rubber rods 304. The anti-skid rubber rods 304 increase the friction of the inner wall of the limit seat 303, improve the stability of the limit seat 303 when clamping the PE pipe, and can provide flexible protection when the limit seat 303 clamps the outer wall of the PE pipe.
[0026] Furthermore, slide bars 206 are fixedly mounted on both sides of the back of the assembly plate 201, and two sets of slip rings 106 are fixedly mounted on the back of the main body 101 for use with the slide bars 206. The slide bars 206 are slidably mounted within the slip rings 106 to reinforce the assembly plate 201 during the extension operation and reduce the pressure of the assembly plate 201 on the electric push rod 205.
[0027] Furthermore, support frames 102 are fixedly mounted on both sides of the bottom of the main base 101, and fixing plates 103 are fixedly mounted on the bottoms of both sets of support frames 102. The support frames 102 can support the bottom of the main base 101, and the fixing plates 103 can fix the bottom of the support frames 102 with bolts, ensuring the stability of the support frames 102 when supporting the main base 101.
