Description

Technical Field

[0001] This invention relates to the field of spiral wound tube processing technology, specifically to a forming device for spiral wound socket joints. Background Technology

[0002] Pipes made by spiral winding are widely used in daily life. They have advantages such as high rigidity and long service life. When two spiral pipes are connected together, a socket connection is used. Socket joints are usually set at both ends of the spiral pipe. Socket joint forming equipment is divided into two types: spiral winding and injection molding. When spiral winding socket joints are produced, a plastic strip needs to be wrapped around the outer surface using forming equipment.

[0003] However, the forming equipment for spiral wound socket joints still has the following shortcomings in the production and processing:

[0004] When using molding equipment to wrap plastic strips around the outer surface of a spiral-wound connector, it is necessary to ensure that the spiral-wound connector remains stable at all times. Furthermore, since the fixing components of the spiral-wound connector on the existing molding equipment are not adjustable, the molding equipment cannot fix spiral-wound connectors with different wall thicknesses, thereby reducing the flexibility of the device during use.

[0005] Furthermore, before wrapping the plastic strip around the spiral-wound connector, the outer surface needs to be cleaned. In actual factory production, manual cleaning is often used, which not only increases the production cost of the spiral-wound connector, but also directly affects the wrapping effect of the connector due to the unsatisfactory cleaning effect.

[0006] Therefore, in view of this, the present invention proposes a forming device for a spiral-wound socket joint to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a forming device for a spiral-wound socket joint, thereby resolving the corresponding technical issues raised in the background section.

[0010] Furthermore, a plurality of cleaning rollers are evenly arranged inside the first support ring, and the cleaning rollers are detachable.

[0011] Furthermore, two sets of propulsion mechanisms are symmetrically arranged inside the second support ring. The two sets of propulsion mechanisms include a circular ring, a collar, a hinged movable plate, and a spring. The circular ring is fixed to the inner wall of the second support ring, the collar is slidably sleeved on the outer wall of the circular ring, the hinged movable plate is fixed to the end of the collar, and the spring is sleeved on the outer walls of the circular ring and the collar. One end of the spring is fixed to the inner wall of the second support ring, and the other end of the spring is fixed to the outer wall of the hinged movable plate.

[0012] Furthermore, a control mechanism is provided on the outer wall of the second support ring. The control mechanism includes a first rod, a second rod, a first buckle, a first limiting plate, a second limiting plate, a third rod, a fourth rod, a second buckle, and a telescopic sleeve. The end of the first rod is fixed to the outer wall of the second support ring. The second rod is located on one side of the first rod.

[0016] Furthermore, the outer contour of the support plate is arc-shaped.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) By setting an adjustable support mechanism, the second connecting rod can push the cylinder to slide inside the support plate under the action of the adjustment mechanism, while the first connecting rod and the support rod push the support plate to rise. When the outer wall of the support plate contacts the inner wall of the spiral type connector, it plays a role in fixing the spiral type connector, so that it remains stable throughout the process of winding the plastic strip. This helps to improve the winding effect. At the same time, by utilizing the sliding distance of the cylinder inside the support plate, the device can meet the fixing of spiral type connectors with different wall thicknesses, thereby helping to improve the flexibility of the device during use.

[0019] (2) By setting a cleaning roller, when the spiral-wound connector passes through the second support ring, the cleaning roller can clean the lint adhering to the surface of the spiral-wound connector, which is convenient for subsequent processing. At the same time, the cleaning roller can be disassembled, which is convenient for staff to replace the cleaning roller regularly, achieving a better cleaning effect on the lint and helping the subsequent processing of the spiral-wound connector.

[0020] (3) By setting a locking mechanism, when the second support ring moves to the designated position and the adjustable support mechanism is fixed to the spiral type connector plug, when the bottom of the irregular plug block contacts the outer wall of the trapezoidal block, the irregular plug block slides upward inside the first block, thereby preventing the limit post from being blocked by the trapezoidal block. Then the limit post is inserted into the mounting plate, thereby limiting the second support ring and preventing the second support ring from being not fixed firmly, which would affect the production of the spiral type connector plug.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Embodiments of the present invention

[0034] The forming equipment for spiral-wound socket joints includes a mold body 1. A work frame 2 is provided on one side of the outer wall of the mold body 1, and an mounting base 3 is also installed on one side of the outer wall of the mold body 1. The mounting base 3 is located above the work frame 2. A first support ring 21 is fixedly connected to the top of the work frame 2 away from the mounting base 3. A second support ring 22 is provided on one side of the first support ring 21. Two support legs 23 are symmetrically arranged on the outer walls of the two sides of the second support ring 22. Two guide rails 24 are symmetrically fixedly connected to the outer wall of the bottom end of the mold body 1. The other ends of the two guide rails 24 are fixedly connected to the side wall of the first support ring 21. The two support legs 23 are slidably connected to the outer walls of the two guide rails 24 respectively. The second support ring 22 can be moved by sliding the two support legs 23 on the outer walls of the guide rails 24. Adjustable support mechanisms are evenly arranged on the outer walls of the mounting base 3. The adjustable support mechanisms include a support plate 41, a cylinder 42, a first connecting rod 43, a support rod 44, a support plate 45, and a second connecting rod 46. The support plate 41 is fixedly connected to the outer wall of the mounting base 3. The cylinder 42 is slidably disposed inside the support plate 41 in the middle section. The first connecting rod 43 is fixed to the end of the cylinder 42. There are two first connecting rods 43 symmetrically arranged about the support plate 41. The support rod 44 is fixed to the other end of the first connecting rod 43. The support plate 45 is fixed to the top of the two support rods 44. One end of the second connecting rod 46 is hinged to the end of the cylinder 42. The outer contour of the support plate 45 is arc-shaped. Under the action of the adjustment mechanism, the second connecting rod 46 can push the cylinder 42 to slide inside the support plate 41. At the same time, the first connecting rod 43 and the support rod 44 push the support plate 45 to rise. When the outer wall of the support plate 45 contacts the inner wall of the spiral-wound connector, it fixes the spiral-wound connector, keeping it stable throughout the process of winding the plastic strip. This helps to improve the winding effect. At the same time, the sliding distance of the cylinder 42 inside the support plate 41 allows the device to fix spiral-wound connectors with different wall thicknesses, thereby improving the flexibility of the device.

[0035] An adjustment mechanism is provided at the end of the mounting base 3 near the outer wall of the mold body 1. The adjustment mechanism includes a rotating shaft 51, a toothed ring 52, a rotating block 53, a guide rod 54, and a support rod 55. One end of the rotating shaft 51 is rotatably connected to the end of the mounting base 3, and the other end of the rotating shaft 51 is rotatably connected to the outer wall of the mold body 1. The toothed ring 52 is fixed to the outer wall of the rotating shaft 51. The rotating block 53 is rotatably connected to the outer wall of the rotating shaft 51. One end of the guide rod 54 is fixed to the end of the mounting base 3, and the other end of the guide rod 54 is fixed to the outer wall of the mold body 1. One end of the support rod 55 is fixed to the outer wall of the rotating block 53, and the other end of the support rod 55 is fixed to the end of the second connecting rod 46. The middle section of the support rod 55 is slidably disposed on the outer wall of the guide rod 54. When the rotating block 53 rotates with the rotating shaft 51, it slides on the outer wall of the guide rod 54 in conjunction with the support rod 55, thereby achieving the purpose of adjusting the height of the support plate 45, which facilitates the use of winding-type connectors with different wall thicknesses.

[0036] Multiple cleaning rollers 6 are evenly arranged inside the first support ring 21. The cleaning rollers 6 are detachable. By setting the cleaning rollers 6, when the winding type receiving plug passes through the second support ring 22, the cleaning rollers 6 can clean the cloth fibers adhering to the surface of the winding type receiving plug, which is convenient for subsequent processing.

[0037] The second support ring 22 has two sets of symmetrically arranged propulsion mechanisms inside. Each set includes a circular ring 71, a collar 72, a hinged movable plate 73, and a spring 74. The circular ring 71 is fixed to the inner wall of the second support ring 22, the collar 72 is slidably sleeved on the outer wall of the circular ring 71, the hinged movable plate 73 is fixed to the end of the collar 72, and the spring 74 is sleeved on the outer walls of the circular ring 71 and the collar 72. One end of the spring 74 is fixed to the inner wall of the second support ring 22, and the other end is fixed to the outer wall of the hinged movable plate 73. The end of the spiral-wound connector contacts the surface of the hinged movable plate 73. Furthermore, when the second support ring... When the second support ring 22 is pushed towards the mounting base 3 by the spiral-type connector, it contacts the support plate 45 through the hinged movable plate 73, causing the hinged movable plate 73 to fold towards the inner wall of the spiral-type connector. At the same time, when the hinged movable plate 73 is pressed by the outer wall of the support plate 45, it slides on the outer wall of the ring 71 through the collar 72, and presses the spring 74, causing the hinged movable plate 73 to move towards the inner wall of the spiral-type connector, thus not affecting the normal operation of the support plate 45. When the second support ring 22 moves into place, the adjustable support mechanism completes the fixation of the spiral-type connector.

[0038] The control mechanism includes a first lever 81, a second lever 82, a first buckle 83, a first limiting plate 84, a second limiting plate 85, a third lever 86, a fourth lever 87, a second buckle 88, and a telescopic sleeve 89. The end of the first lever 81 is fixed to the outer wall of the second support ring 22. The second lever 82 is positioned to one side of the first lever 81. The bottom end of the first buckle 83 is fixed to the end of the second lever 82, and the top end of the first buckle 83 is slidably connected to the outer wall of the first lever 81. The first limiting plate 84 is fixed... Connected to the other end of rod 81, the second limiting plate 85 is fixed to the top of rod 81, the first buckle 83 is located between the first limiting plate 84 and the second limiting plate 85, one end of rod 86 is fixed to the outer wall of mold body 1, the other end of rod 86 is fixed to the end of rod 87, the bottom end of the second buckle 88 is fixed to the other end of rod 82, the top end of the second buckle 88 is slidably connected to the outer wall of rod 87, and a telescopic sleeve 89 is provided in the middle section of rod 87.

[0039] The end of rod 87 is connected to a transmission mechanism, which includes a fixed block 90, a transmission rod 91, a bevel gear 92, a turntable 93, and a connecting rod 94. The fixed block 90 is fixed to the outer wall of the mold body 1. The middle section of the transmission rod 91 is rotatably connected inside the fixed block 90. ​​The bevel gear 92 is fixed to the end of the transmission rod 91 and meshes with the gear ring 52. The turntable 93 is fixed to the other end of the transmission rod 91. One end of the connecting rod 94 is hinged to the end of rod 87, and the other end of the connecting rod 94 is hinged to the outer wall of the turntable 93. The turntable 93 rotates the transmission rod 91 and the bevel gear 92, thereby enabling the adjustment mechanism to operate and fixing the winding type connector plug.

[0040] The outer wall of the second support ring 22 is provided with a locking mechanism, which includes a shaped insert 101, a cover plate 102, a limiting post 103, a second block 104, a trapezoidal block 105, and a mounting plate 106. A first block 100 is fixedly connected to the outer wall of the second support ring 22. The bottom end of the shaped insert 101 is inserted into the first block 100. The cover plate 102 is fixedly connected to the top of the shaped insert 101 and is located above the first block 100. The limiting post 103 is fixedly connected to the bottom of the cover plate 102. The second block 104 is fixedly connected to the outer wall of the mold body 1. The trapezoidal block 105 is fixedly connected to the top of the second block 104. The mounting plate 106 is fixedly connected to the top of the second block 104 and is located above the trapezoidal block 105. On one side, the limiting post 103 is inserted into the mounting plate 106; two sets of locking mechanisms are symmetrically arranged on the outer wall of the second support ring 22. By setting the locking mechanism, when the second support ring 22 moves to the designated position and the adjustable support mechanism is fixed to the spiral type connector plug, when the bottom of the irregular plug 101 contacts the outer wall of the trapezoidal block 105, the irregular plug 101 slides upward inside the first block 100, thereby preventing the limiting post 103 from being obstructed by the trapezoidal block 105. Then the limiting post 103 is inserted into the mounting plate 106, thereby limiting the second support ring 22 and preventing the second support ring 22 from being not fixed firmly, which would affect the production of the spiral type connector plug.

[0041] The complete usage steps and working principle of the above embodiments are as follows:

[0042] When using the device, the operator inserts the pipe socket into the first support ring 21, so that the surface of the pipe socket comes into contact with the cleaning roller 6, and the cleaning roller 6 cleans off the lint adhering to the surface of the pipe socket, which is convenient for subsequent processing. At the same time, since the cleaning roller 6 is detachable, it is convenient for the operator to replace the cleaning roller 6 regularly, so as to achieve a better cleaning effect of lint.

[0043] Subsequently, the end of the pipe socket joint contacts the surface of the hinged movable plate 73. By pushing the pipe socket joint forward, the second support ring 22 slides on the surface of the guide rail 24 in conjunction with the support foot 23. The second support ring 22 then moves the first rod 81, causing the second limiting plate 85 at the top of the first rod 81 to push the first retaining ring 83 to move. When the second rod 82 moves, the second retaining ring 88 slides on the outer wall of the fourth rod 87, and at the same time, it squeezes the telescopic sleeve 89. Finally, the fourth rod 87 rotates the turntable 93 through the connecting rod 94. When the turntable 93 rotates, it causes the transmission rod 91 to rotate, causing the bevel gear 92 to rotate as well. Due to the meshing of the gear ring 52 and the bevel gear 92, the gear ring 52 rotates the rotating shaft 51. When 51 rotates, it causes the rotating block 53 to rotate, and at the same time, the support rod 55 slides on the outer wall of the guide rod 54, so that the support rod 55 pushes the second connecting rod 46 to move. When the second connecting rod 46 moves, the cylinder 42 slides inside the support plate 41, and at the same time, it lifts the support rod 44 and the support plate 45 through the first connecting rod 43, so that the top of the support plate 45 can contact the inner wall of the pipe socket joint, thereby fixing the pipe socket joint and keeping the outer wall of the pipe socket joint stable when the plastic strip is wrapped. With the support rod 55 sliding on the outer wall of the guide rod 54, the height of the support plate 45 can be adjusted, so that the device can fix pipe socket joints with different wall thicknesses, thereby improving the flexibility of the device during use.

[0044] When the support plate 45 contacts the inner wall of the pipe socket joint, the bottom of the irregularly shaped plug 101 will contact the outer wall of the trapezoidal block 105, allowing the irregularly shaped plug 101 to slide upward inside the first block 100 under the pressure. After the irregularly shaped plug 101 is no longer squeezed by the trapezoidal block 105, the limiting post 103 falls into the mounting plate 106, which can then lock the adjustable support mechanism and help improve the stability of the device.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
