Technical Field

[0001] The present invention relates to the technical field of PP pipe processing, and more specifically, to a PP pipe rapid welding processing system accurately positioned at a processing point. Background Art

[0002] PP pipe is a non-toxic, hygienic, high temperature resistant and recyclable pipe type. It is mainly used in indoor hot and cold water supply systems of buildings and is also widely used in heating systems. The characteristics of PP pipe are corrosion-resistant, wear-resistant, non-scaling, reduced vibration and noise, anti-freezing and cracking, anti-condensation, less heat loss, simple installation and long service life.

[0003] In production and construction, it is often necessary to butt-weld and lengthen the multi-section pipe body according to the actual production and construction needs, or butt-weld the different types of pipe bodies to increase the practicality of the PP pipe. Since it is necessary to face PP pipes of various sizes, especially butt-welding with a relatively complete range of sizes, a relatively complete butt-welding device is required, which will cause frequent replacement, increase the workload, and the replaced parts and parts to be replaced will occupy a large number of construction areas; for example, the prior art of a high-temperature resistant PP pipe rapid welding device and its processing method (Chinese patent, authorization announcement number CN113681912B) records that "when it is necessary to weld pipes of different sizes... replace the bottom clamp block with the size of the clamp groove corresponding to the pipe body to be processed". There is also a problem in that when facing butt-welding of PP pipes with a relatively complete range of sizes, frequent replacement is required, which increases the workload, and the replaced parts and parts to be replaced will occupy a large number of construction areas.

[0004] Based on this, a PP pipe rapid welding processing system which can accurately locate the processing point is proposed to solve the above problems. Summary of the invention

After using multiple docking ring assemblies one and multiple docking ring assemblies two to push the two PP pipes from both sides to the heating hot melt ring, multiple alignment frames are synchronously started, and multiple alignment frames synchronously push the PP pipes on both sides of the heating hot melt ring from all sides; on the one hand, it can improve the alignment of the PP pipes on both sides at the heating hot melt ring, and improve the quality of the PP pipe welding process; on the other hand, it can achieve the stability of the heating hot melt ring during the welding process, avoiding the influence of some vibrations of its own operation or other external vibrations.

[0049] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0050] In the embodiment of the present invention, Figure 1-Figure 3 : A PP pipe rapid welding processing system accurately positioned at a processing point, comprising a base 1 equipped with a heating hot melt ring 3, a PP pipe docking frame 2 slidably mounted on the base 1, the PP pipe docking frame 2 comprising a plurality of docking ring assemblies 100 and a plurality of docking ring assemblies 200, the docking ring assemblies 100 and the docking ring assemblies 200 adopt the same structure;

[0051] It should be noted that the number of "a plurality of docking ring assemblies 100 and a plurality of docking ring assemblies 200" can be two, three, four, five, etc., and there is no restriction on the specific number, as long as it can be used to push the two PP pipes 6 from both sides. Here, it is preferred that the specific number of the plurality of docking ring assemblies 100 and the plurality of docking ring assemblies 200 is two;

[0052] Please continue reading Figure 3 and Figure 5 The docking ring assembly 100 includes a driving frame 110 and a docking ring 120. The docking ring 120 includes two symmetrically distributed buckling half rings 121. The driving frame 110 is used to drive the two buckling half rings 121 to separate and open. After the PP tube 6 is placed, the two buckling half rings 121 are driven to approach each other for buckling;

[0053] The buckling half ring 121 includes a buckling half ring body 123 and a plurality of telescopic support legs 122, and the plurality of telescopic support legs 122 are distributed inside the buckling half ring body 123 along the main body array of the buckling half ring body 123;

[0054] The multiple telescopic support legs 122 are synchronously telescopically extended to adjust the support radius of the buckled half ring 121, which is suitable for PP tubes 6 of various sizes;

[0055] Therefore, when facing the butt welding of PP pipes 6 with a relatively complete range of sizes, frequent replacement is required, which increases the workload of the operation, and the replaced parts and the parts to be replaced will occupy a large number of construction areas; this application can achieve:

[0056] In the process of switching PP tubes 6 of different sizes, the two buckling half rings 121 are first separated and opened by the driving frame 110, and the support radius of the buckling half ring 121 is adjusted by using multiple telescopic support legs 122 to insert the PP tube 6, and then the two buckling half rings 121 are driven close to each other for buckling; finally, multiple docking ring assemblies 100 and multiple docking ring assemblies 200 are used to push the two PP tubes 6 from both sides toward the heated hot melt ring 3; that is, multiple telescopic support legs 122 are synchronously extended and retracted, so as to realize the rapid and flexible adjustment of the support radius of the buckling half ring 121, and to simply and efficiently support the PP tube 6 with limited position, thus avoiding frequent replacement of the docking ring 120, reducing the operating workload, and avoiding the situation where a large number of construction areas are occupied due to the parts that need to be replaced.

[0057] In the embodiment of the present invention, Figure 5 and Figure 6 As shown: the buckled semi-ring body 123 is provided with a plurality of slide grooves 124, the plurality of slide grooves 124 are in one-to-one correspondence with the plurality of telescopic support legs 122, and the plurality of slide grooves 124 are distributed on the buckled semi-ring body 123 along the main body array of the buckled semi-ring body 123;

[0058] The telescopic support leg 122 is slidably assembled inside the slide groove 124, and a hydraulic telescopic rod four is assembled inside the slide groove 124. The hydraulic telescopic rod four is used to adjust the position of the telescopic support leg 122 along the slide groove 124 on the buckled semi-ring body 123.

[0059] Therefore, when facing some shapes on the outside of the PP tube 6 and some special-shaped structures of its own part, the hydraulic telescopic rod four on one or more telescopic support legs 122 is used to adjust the position of the telescopic support legs 122 along the slide groove 124 on the buckled semi-ring body 123 through the hydraulic telescopic rod four, so that the local multiple telescopic support legs 122 are concentrated on the local multiple suitable force support points of the PP tube 6 (for details, please refer to Fig. 9 F in the figure is a demonstration of the centralized telescopic support leg clamping of the PP pipe by the docking ring, wherein it can be specifically understood by the telescopic support legs centrally supporting the PP pipe area 7); on the basis of ensuring stable clamping of the PP pipe 6, the staggered centralized support is utilized at multiple suitable local force support points to avoid some external shapes of the PP pipe 6 and some local special-shaped structures thereof, thereby improving adaptability.

[0060] In the embodiment of the present invention, Figure 6 and Figure 7 As shown: the telescopic support leg 122 includes a support plate 1221 and a telescopic rod structure 1222, the support plate 1221 is installed at the end of the telescopic rod structure 1222; the telescopic rod structure 1222 includes a hydraulic telescopic rod 1224 and a telescopic rod 1225;

[0061] There are two hydraulic telescopic rods 1224 and they are distributed on both sides of the end of the telescopic rod 1225 . The hydraulic telescopic rod 1224 is rotatably equipped with a U-shaped connecting plate 1223 at one end away from the telescopic rod 1225 , and the U-shaped connecting plate 1223 is fixed on the abutment plate 1221 .

[0062] Therefore, when directly facing some shapes outside the PP tube 6, the hydraulic telescopic rod 1224 on one side of the end of the telescopic rod 1225 is extended, and the hydraulic telescopic rod 1224 on the other side is shortened to achieve tilt adjustment of the abutment plate 1221 (for details, please refer to Figure 8 A is a demonstration of a normal angle of the abutment plate 1221 and B is a demonstration of an inclined angle of the abutment plate 1221, and Fig. 9E in the middle is a demonstration of the clamping of the docking ring on the PP tube shaping area, wherein the telescopic support legs can be used to adjust the angle area 4 and the PP tube shaping area 5 according to the shaping), and the telescopic support legs 122 can use the inclined abutment plates 1221 to align at a suitable angle with some shapes on the outside of the PP tube 6, avoiding the sides and corners of the abutment plates 1221 and abutting against some shapes on the outside of the PP tube 6, causing damage to the PP tube 6 body, which is used to improve the rapid welding process of the PP tube.

[0063] In the embodiment of the present invention, Figure 5 and Figure 7 As shown: the telescopic rod 1225 is fixed with a guide slider 1226 at its end, the guide slider 1226 is in the shape of an "I", and the guide slider 1226 is slidably assembled inside the slide groove 124. The guide slider 1226 has arc surfaces on both sides of the contact surface with the slide groove 124; one end of the hydraulic telescopic rod 4 is fixed on the guide slider 1226, and the other end is fixed inside the slide groove 124.

[0064] In the embodiment of the present invention, Fig.14 and Fig.15 As shown: the telescopic rod 1225 includes an interpenetrating column 12252 and a receiving tube 12253, the interpenetrating column 12252 is movably interpenetrated in the receiving tube 12253, the interpenetrating column 12252 is provided with a piston 12254 in the receiving tube 12253, and the interpenetrating column 12252 is fixed with a fixed plate 12251 at the end away from the piston 12254; two hydraulic telescopic rods 1224 are distributed on both sides of the end of the fixed plate 12251.

[0065] like Fig.15 As shown: the piston 12254 is connected to two springs 12255, and the two springs 12255 are connected to the bottom of the storage tube 12253;

[0066] The piston 12254 is provided with a plurality of sets of electromagnetic coils on the contact surface with the storage tube 12253 . By turning the power on and off for the plurality of sets of electromagnetic coils, the piston 12254 can be controlled to be magnetic, thereby completing the switching of limiting and releasing the limiting inside the storage tube 12253 .

[0067] It should be noted that: multiple sets of electromagnetic coils and the power wiring methods of multiple sets of electromagnetic coils are all existing technologies, and their detailed structures can be learned from existing literature journals, and can also be directly purchased on the market, or can be assembled from parts purchased on the market, etc.; they are not what the present invention is intended to protect, and will not be elaborated here, nor drawn in the accompanying drawings;

[0068] Therefore, in the process of switching PP tubes 6 of different sizes, the two buckling half rings 121 are first separated and opened through the driving frame 110, and the multiple sets of electromagnetic coils are powered off to lose magnetic adsorption, and the piston 12254 is released from the limit inside the storage tube 12253, and the PP tube 6 is inserted, so that the PP tube 6 adaptively and synchronously squeezes the multiple telescopic support legs 122, so that the multiple telescopic support legs 122 quickly retract and adjust the support radius of the buckling half ring 121, and then the multiple sets of electromagnetic coils are powered on to make the piston 12254 magnetic, and the piston 12254 is limited inside the storage tube 12253, so as to realize fast, efficient and precise adaptive adjustment of the support radius of the buckling half ring 121, so as to accurately and flexibly respond to PP tubes 6 of different sizes, and improve the efficiency of subsequent PP tube rapid welding processing.

[0069] In the embodiment of the present invention, Figure 4 As shown: the driving frame 110 includes a U-shaped support plate 1102 and an arc-shaped support plate 1103, the U-shaped support plate 1102 is fixed to the side of the arc-shaped support plate 1103, and a hydraulic telescopic rod 1101 is fixed to the side of the U-shaped support plate 1102 away from the arc-shaped support plate 1103, and the hydraulic telescopic rod 1101 points to the arc-shaped support plate 1103;

[0070] The two buckling half rings 121 are fixed on the hydraulic telescopic rod 1101 and the arc-shaped support plate 1103 respectively.

[0071] Further, such as Figure 4 and Fig.16 As shown: the arc-shaped support plate 1103 is mounted on the guide plate 1104 through a hydraulic telescopic rod 5, the guide plate 1104 is slidably assembled on the guide rail 1105, and the guide rail 1105 is mounted on the base 1.

[0072] Therefore, when facing the curved PP pipe 8, first adjust the distance between the multiple docking ring components 100 and the distance between the multiple docking ring components 200 through the guide rail 1105, and at the same time cooperate with the hydraulic telescopic rod 5 to adjust the height of the local multiple docking ring components 100 and the docking ring components 200 to complete the adaptation to the curvature of the curved PP pipe 8 (for details, please refer to Fig.16 The method mentioned in the text is suitable for clamping the bent PP pipe 8), which is beneficial to the subsequent positioning and rapid welding; thereafter, the two buckling half rings 121 are brought close to each other through the hydraulic telescopic rod 1101 for buckling; that is, by adjusting the distance between one or more docking ring components 100 and the distance between multiple docking ring components 200, and then adjusting the height of one or more docking ring components 100 and / or multiple docking ring components 200, a misalignment difference is formed, so as to adapt to the different curvatures of different curved PP pipes 8 with different curvatures at one or more places, thereby improving the subsequent positioning accuracy and efficiency, and facilitating the rapid positioning and welding processing of the PP pipe.
