Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, specifically to a multi-directional integrated molding equipment for U-shaped pipe fittings. Background Technology

[0002] U-shaped pipe fittings are widely used in construction, electromechanical, and heat exchange fields. Their forming equipment is mainly divided into manual, automatic, and injection molding types. Existing manual forming devices require manual operation for bending, which is time-consuming, labor-intensive, inefficient, and makes it difficult to guarantee forming accuracy. Automatic forming equipment mostly uses a single rolling or bending method, which can only achieve basic U-shaped structure forming and cannot complete the integrated processing of multi-directional structures. Although some injection molding molds can form U-shaped pipe fittings, they have problems such as high demolding resistance, easy marks left on the pipe surface, and short mold life, and are not suitable for multi-directional structure forming of metal U-shaped pipe fittings. Existing equipment generally suffers from defects such as scattered forming processes, poor multi-directional structure connection accuracy, and insufficient adaptability, making it difficult to balance forming efficiency and quality, and unable to meet the actual needs of integrated multi-directional structure forming of U-shaped pipe fittings. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-directional integrated molding equipment for U-shaped pipe fittings, so as to solve the problems of complex structure, low molding accuracy and complicated molding process of traditional U-shaped pipe molding equipment mentioned in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional integrated molding device for U-shaped pipe fittings, comprising a motor, a tubular molding component, and an end molding component. The tubular molding component and the end molding component are detachably connected. The tubular molding component includes a first molding block and a second molding block. Grooves are provided on the first and second molding blocks corresponding to the U-shaped pipe fitting molding positions. After the first and second molding blocks are combined, the corresponding two grooves combine to form an arc groove for molding the U-shaped pipe body. The arc groove has an arc tube for molding the through U-shaped pipe fitting. The end molding component includes a lower part corresponding to the lower end of the U-shaped pipe body. A spoon part for supporting the arc tube is provided on the lower part facing the arc tube. The arc tube and the spoon part are sealed together. The radial width of the arc groove is greater than the radial width of the arc tube. A pipe body molding gap is formed between the arc groove and the arc tube. An end molding gap is formed between the arc groove and the end molding component. The combination of the first molding block, the second molding block, and the end molding component enables the U-shaped pipe fitting to be integrally molded.

[0005] As a further improvement of this utility model, the end forming assembly includes an upper part corresponding to the upper end of the U-shaped tube body and a side part corresponding to the side end of the U-shaped tube body. The upper part is positioned at the upper end of the arc groove, and the side part is positioned at the side end of the arc groove. An upper contraction portion extends into the arc groove from the upper part, a side contraction portion extends into the arc groove from the side part, and a lower contraction portion extends into the arc groove from the lower part. The lower contraction portion is integrally formed with the spoon portion, and the upper contraction portion, the lower contraction portion, and the side contraction portion are all inserted into the arc groove.

[0006] As a further improvement of this utility model, the arc tube extends toward the end forming assembly and is provided with a guide shaft, the guide shaft is partially inserted into the end forming assembly, and the end forming assembly can move along the length direction of the guide shaft.

[0007] As a further improvement of this utility model, the end forming assembly includes a box body, on which a limiting window is provided, and the guide shaft passes through the limiting window and can reciprocate within the limiting window.

[0008] As a further improvement of this utility model, the housing is provided with a receiving cavity, and the components in the end forming assembly can slide along the guide shaft and retract into the receiving cavity after processing.

[0009] Compared with existing technologies, this utility model provides a multi-directional integrated molding device for U-shaped pipe fittings, which has the following advantages: the tubular molding component and the end molding component are detachably connected, allowing for convenient disassembly, maintenance, and replacement of components, thus improving the flexibility of the equipment. The grooves of the first and second molding blocks combine to form an arc groove, which, together with the arc tube within the arc groove and the pipe forming gap between them, allows for precise control of the molding size and wall thickness uniformity of the U-shaped pipe body. The arc tube also ensures the through-core characteristic of the fitting. The spoon-shaped part of the end molding component provides stable support and a sealed connection for the arc tube, preventing material leakage during the molding process. The end forming gap between the arc groove and the end molding component determines the end position of the U-shaped pipe, ensuring a smooth connection between the end and the pipe body.

[0017] As shown in the figure, to achieve the above objectives, this utility model provides a multi-directional integrated molding device for U-shaped pipe fittings, including a motor 1, a tubular forming component 2, and an end forming component 3. The tubular forming component 2 and the end forming component 3 are detachably connected. The tubular forming component 2 includes a first forming block 4 and a second forming block 5. Grooves 6 are provided on the first forming block 4 and the second forming block 5 at positions corresponding to the U-shaped pipe fitting forming. After the first forming block 4 and the second forming block 5 are combined, the two corresponding grooves 6 combine to form an arc groove for forming the U-shaped pipe body. 7. The arc groove 7 has an arc tube 8 for forming a through U-shaped tube. The end forming component 3 includes a lower part 9 corresponding to the lower end of the U-shaped tube body. The lower part 9 is provided with a spoon part 10 for supporting the arc tube 8. The arc tube 8 and the spoon part 10 are sealed together. The radial width of the arc groove 7 is greater than the radial width of the arc tube 8. A tube body forming gap 11 is formed between the arc groove 7 and the arc tube 8. An end forming gap 12 is formed between the arc groove 7 and the end forming component 3. The first forming block 4, the second forming block 5, and the end forming component 3 are combined to form the U-shaped tube integrally.

[0018] In implementation, the equipment comprises a motor 1, a tubular forming assembly 2, and an end forming assembly 3. The tubular forming assembly 2 and the end forming assembly 3 are detachably connected, using bolts, snap-fit ​​connections, or plug-in joints for easy maintenance, parts replacement, and adaptation to different U-shaped pipe fitting specifications. The tubular forming assembly 2 consists of a first forming block 4 and a second forming block 5, which are symmetrical. Each block has a groove 6 at a preset position corresponding to the U-shaped pipe fitting. The shape of the groove 6 matches the contour of the U-shaped pipe fitting. When the first forming block 4 and the second forming block 5 are aligned and molded, the two corresponding grooves 6 precisely combine to form an arc groove 7 for forming the U-shaped pipe fitting. The curvature of the arc groove 7 matches the bending curvature of the target U-shaped pipe fitting. An arc tube 8 is fixedly installed inside the arc groove 7. This arc tube 8 is used to form a through U-shaped pipe fitting, ensuring that the formed U-shaped pipe fitting has a continuous inner cavity. The end forming assembly 3 includes a lower part 9 corresponding to the lower end of the U-shaped tube body. A spoon portion 10 is integrally formed on one end of the lower part 9 facing the arc tube 8. The outline of the spoon portion 10 matches the shape of the lower end of the U-shaped tube, and the arc tube 8 and the spoon portion 10 are sealed together. A sealing ring can be used to achieve a seal, preventing material leakage during the forming process. The radial width of the arc groove 7 is greater than the radial width of the arc tube 8, forming a tube body forming gap 11 between them. This gap is used to accommodate the forming material, which is formed within the gap to create the U-shaped tube body. Simultaneously, an end forming gap 12 is formed between the arc groove 7 and the end forming assembly 3. During operation, the motor 1 provides power to drive the tubular forming assembly 2 to close the mold, injecting the forming material into the tube body forming gap 11 and the end forming gap 12. Through the coordinated cooperation of the first forming block 4, the second forming block 5, and the end forming assembly 3, the U-shaped tube is integrally formed, eliminating the need for subsequent secondary processing of the tube body and end, thus improving processing efficiency.

[0019] As an improved specific embodiment, the end forming assembly 3 includes an upper part 13 corresponding to the upper end of the U-shaped tube body and a side part 15 corresponding to the side end 14 of the U-shaped tube body. The upper part 13 is positioned at the upper end of the arc groove 7, and the side part 15 is positioned at the side end 14 of the arc groove 7. An upper contraction part 16 extends from the upper part 13 toward the arc groove 7, a side contraction part 17 extends from the side part 15 toward the arc groove 7, and a lower contraction part 18 extends from the lower part 9 toward the arc groove 7. The lower contraction part 18 is integrally formed with the spoon part 10, and the upper contraction part 16, the lower contraction part 18, and the side contraction part 17 are all inserted into the arc groove 7.

[0020] In implementation, the upper part 13, lower part 9, and side part 15 correspond to the three ends of the U-shaped tube, achieving simultaneous forming of the three ends of the U-shaped tube. The upper part 13 is fixedly positioned at the upper end of the arc groove 7, and the side part 15 is fixedly positioned at the side end 14 of the arc groove 7. These three parts correspond to the positions of the tubular forming component 2, ensuring smooth connection between the formed ends and the tube body. The upper part 13 has an upper contraction section 16 extending towards the arc groove 7, the side part 15 has a side contraction section 17 extending towards the arc groove 7, and the lower part 9 has a lower contraction section 18 extending towards the arc groove 7. The lower contraction section 18 is integrally formed with the spoon part 10, ensuring structural integrity and stability, and preventing material leakage or end forming defects caused by the separation of the contraction section from the spoon part 10 during the forming process. The dimensions of the upper shrinkage portion 16, lower shrinkage portion 18, and side shrinkage portion 17 are adapted to the dimensions of the arc groove 7, and are all inserted into the arc groove 7. The ends of the shrinkage portions are in contact with the outer wall of the arc tube 8, further improving the sealing effect. During operation, after the first forming block 4 and the second forming block 5 are molded together, the upper part 13, the lower part 9, and the side part 15 are simultaneously connected with the tubular forming component 2. The upper shrinkage portion 16, lower shrinkage portion 18, and side shrinkage portion 17 are respectively inserted into the corresponding positions of the arc groove 7, forming the tube body forming gap 11 and the three end forming gaps 12 together with the arc tube 8 and the arc groove 7. After the raw material is injected, the U-shaped tube body and the three ends can be integrally formed in one go, ensuring the connection strength between each end and the tube body, while improving the forming accuracy.

[0021] As an improved specific implementation, the arc tube 8 is provided with a guide shaft 19 extending toward the end forming assembly 3. The guide shaft 19 is partially inserted into the end forming assembly 3, and the end forming assembly 3 can move along the length direction of the guide shaft 19.

[0022] In this design, a guide shaft 19 is integrally extended from the arc tube 8 toward the end forming assembly 3. The axis of the guide shaft 19 is parallel to the axis of the arc tube 8 and can be made of high-strength steel to ensure structural strength. The end forming assembly 3 has a through hole adapted to the guide shaft 19, with a portion of the guide shaft 19 passing through this through hole, allowing the end forming assembly 3 to reciprocate along the length of the guide shaft 19. The guide shaft 19 serves as a guide and limiter, preventing the end forming assembly 3 from shifting during movement and ensuring the alignment accuracy between the end forming assembly 3 and the tubular forming assembly 2. The length of the guide shaft 19 is set according to the travel distance of the end forming assembly 3, and a limit block is provided at its end to prevent the end forming assembly 3 from detaching from the guide shaft 19. During operation, motor 1 drives end forming component 3 to move along guide shaft 19 towards tubular forming component 2 until end forming component 3 aligns with tubular forming component 2. At this point, the spoon portion 10 and the arc tube 8 are sealed together, and the arc groove 7 forms an end forming gap 12 with end forming component 3. After forming, motor 1 drives end forming component 3 to move away from tubular forming component 2 along guide shaft 19, facilitating the removal of the formed U-shaped tube and also facilitating cleaning and maintenance of the equipment's interior. This structure, through the guiding action of guide shaft 19, improves the operational stability and forming accuracy of the equipment, ensuring that the specifications of the U-shaped tubes formed each time are consistent.

[0023] As an improved specific implementation, the end forming assembly 3 includes a housing 20, on which a limiting window 21 is provided, and a guide shaft 19 passes through the limiting window 21 and can reciprocate within the limiting window 21.

[0024] In implementation, the end forming assembly 3 includes a hollow housing 20 for mounting various components of the end forming assembly 3. The housing 20 can be made of cast iron or aluminum alloy, possessing sufficient structural strength and stability. A limiting window 21 is provided on the side of the housing 20 facing the tubular forming assembly 2, its length direction aligned with the length direction of the guide shaft 19. The guide shaft 19 passes through the limiting window 21 and extends into the housing 20, allowing it to reciprocate along its length within the limiting window 21. The width of the limiting window 21 is matched to the diameter of the guide shaft 19, ensuring smooth movement of the guide shaft 19 while also providing lateral restraint to prevent lateral deviation during movement, further improving the docking accuracy between the end forming assembly 3 and the tubular forming assembly 2. During operation, as the end forming component 3 moves along the guide shaft 19, the guide shaft 19 moves synchronously within the limiting window 21. The limiting window 21 limits the movement trajectory of the guide shaft 19, ensuring that the end forming component 3 always moves in the preset direction, thus avoiding forming defects caused by deviation. At the same time, the housing 20 can protect the components of the end forming component 3, preventing raw materials from splashing or debris from entering during processing, which would affect the normal operation of the equipment.

[0025] As an improved specific implementation, the housing 20 is provided with a receiving cavity 22, and the parts in the end forming assembly 3 can slide along the guide shaft 19 and retract into the receiving cavity 22 after the parts are processed.

[0026] In implementation, this solution includes a accommodating cavity 22 inside the housing 20. The accommodating cavity 22 is a hollow cavity whose dimensions are adapted to the dimensions of the components in the end-forming assembly 3, serving to house the movable components within the end-forming assembly 3. After the U-shaped tube is formed, the motor 1 drives the guide shaft 19, causing the components of the end-forming assembly 3 to move along the guide shaft 19 into the housing 20 until all components are completely retracted into the accommodating cavity 22, thus achieving component storage.

[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
