Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a pipe taper extraction processing device. Background Technology

[0002] Bicycle frames are assembled and welded together from several different tubular components. These tubular components typically have different outer diameters, and the components often have specific shapes. Welding these components together requires ensuring that there are no gaps between the larger and smaller outer diameter components. A taper process is commonly used to treat these components. Larger outer diameter components are partially or completely tapered according to the design requirements, creating a continuous tube with unequal circumferences. The taper process involves placing the component into a taper die, where a machine continuously strikes the component, generating noise levels approaching 100 decibels, posing a significant health hazard to workers, and producing components with poor surface quality.

[0003] In existing technologies, the tapering process often replaces the taper process for processing pipes with varying circumferences and wall thicknesses, such as round pipes. Taper tapering uses a mandrel with an unequal outer diameter as an inner core, passing through the material pipe. The mandrel's front end presses against the small-diameter beveled section of the material pipe's front end, driving the material pipe through a tapered mold. The tapered mold's taper is designed to match the final taper of the material pipe. After the mandrel drives the material pipe through the tapered mold, it then pulls the shaped pipe back. At this point, the original material pipe with uniform diameter becomes a pipe with unequal circumferences. However, for longer pipes, the mandrel experiences significant forward resistance at the front end, and the friction is very high as the small-diameter beveled section of the material pipe passes through the tapered mold and as the mandrel pulls the shaped pipe back out of the tapered mold. Often, the mandrel punctures the material pipe during forward movement and cannot smoothly bring the pipe back during retraction, leading to the scrapping of the pipe.

[0004] Therefore, a pipe taper extraction processing device is needed to solve the above problems. Utility Model Content

[0034] During the tapering process of pipe fittings, in order to smoothly complete the pipe pulling and unloading operations, such as... Figures 1-2 As shown, this utility model provides a pipe taper extraction processing device. The pipe taper extraction processing device includes a frame, a first driving component 2, a mandrel 3, a forward pushing mechanism 4, and a material ejection mechanism 6.

[0035] The machine frame includes a tapered die 1. A first driving component 2 is fixedly mounted on the machine frame. A mandrel 3 is connected to the first driving component 2, allowing the material tube 100 to be fitted onto the mandrel 3. The first driving component 2 drives the mandrel 3 to move the material tube 100 along a first direction to pass through the tapered die 1. A pushing mechanism 4 abuts against the tail end of the material tube 100, pushing the material tube 100 along the first direction. A material ejection mechanism 6 is mounted on the machine frame. The material ejection mechanism 6 and the first driving component 2 can move the mandrel 3 in the opposite direction of the first direction, causing the mandrel 3 to pull the plasticized material tube 100 out of the tapered die 1 and separate it.

[0036] With the above configuration, the push mechanism 4, in cooperation with the first drive component 2, can effectively push the mandrel 3 and the material tube 100 to move, thereby completing the tube drawing process. The first drive component 2, in cooperation with the ejection mechanism 6, can smoothly push the shaped material tube 100 and mandrel 3 out of the tapered mold 1, thereby completing the ejection action, ensuring the smooth tapered tube drawing process and guaranteeing processing quality.

[0037] In some embodiments, the forward pushing mechanism 4 includes a driving component and a first push plate 41. The first push plate 41 is slidably sleeved on the mandrel 3 and can abut against the tail end of the material tube 100. The driving component is drively connected to the first push plate 41 and is used to drive the first push plate 41 to move along a first direction. By driving the first push plate 41 to move relative to the mandrel 3 through the driving component, a thrust is provided at the tail end of the material tube 100. The first driving member 2 drives the mandrel 3 to move the small-diameter inclined section after the front end abutment, and the first push plate 41 pushes the tail end of the material tube 100, so that the material tube 100 smoothly passes through the tapered die 1 for tapered shaping under the action of dual forces.

[0038] In some embodiments, the driving assembly includes a second push plate 42 and an elastic element 43. The elastic element 43 is disposed between the first push plate 41 and the second push plate 42. One end of the elastic element 43 abuts against the first push plate 41, and the other end of the elastic element 43 abuts against the second push plate 42. The second push plate 42 is drively connected to the first driving member 2. In this embodiment, the elastic element 43 is a compression spring and is sleeved on the mandrel 3. When the first driving member 2 drives the mandrel 3 to move, the second push plate 42 is simultaneously driven by the first driving member 2 to move along a first direction. The second push plate 42 compresses the elastic element 43, and the elastic element 43 transmits elastic force to the first push plate 41. The first push plate 41 abuts against the material tube 100, thereby pushing the material tube 100 to move along the first direction. With the above-described arrangement, there is no need to arrange a separate driving member, thereby reducing costs and control complexity. In other embodiments, a separate drive unit can be arranged on the frame. The drive unit is connected to the first push plate 41 for transmission. The drive unit directly drives the first push plate 41 to move, thereby pushing the material tube 100 to move relative to the tapered mold 1 for shaping. The drive unit can be a linear drive mechanism such as a hydraulic cylinder, pneumatic cylinder, or electric cylinder, or it can be a gear rack structure or a lead screw and nut structure. No further restrictions are imposed here.

[0039] In some embodiments, the pipe taper extraction processing device further includes a first guide post 5, which is fixedly mounted on the first driving member 2 and extends along a first direction. A first push plate 41 and a second push plate 42 are both sleeved on the first guide post 5. By providing the first guide post 5, the movement of the first push plate 41 and the second push plate 42 can be guided, thereby ensuring smoother movement of the first push plate 41 and the second push plate 42 along the first direction, and enabling the force exerted by the first push plate 41 on the material pipe 100 to effectively push the material pipe 100 to move.

[0040] In some embodiments, a first linear bearing 411 is fixedly mounted on the first push plate 41, and a second linear bearing 421 is fixedly mounted on the second push plate 42. Both the first linear bearing 411 and the second linear bearing 421 are sleeved on the first guide post 5. By providing the first linear bearing 411 and the second linear bearing 421, the movement of the first push plate 41 and the second push plate 42 relative to the first guide post 5 can be made smoother, reducing friction.

[0041] In some embodiments, the first driving component 2 is a hydraulic cylinder, with its piston rod connected to one end of the mandrel 3, and the second push plate 42 fixedly sleeved on the piston rod of the first driving component 2. Using a hydraulic cylinder as the first driving component 2 ensures high thrust, and the direct connection between the first driving component 2 and the mandrel 3 results in a simple structure. When the piston rod of the first driving component 2 extends, it moves the mandrel 3 while simultaneously driving the second push plate 42. In other embodiments, the driving component can be a linear drive mechanism such as a pneumatic cylinder or an electric cylinder, or it can be a gear and rack structure or a lead screw and nut structure; no further restrictions are imposed here.

[0042] In some embodiments, the ejection mechanism 6 includes a support frame, a second drive member 65, and a push plate 64. The support frame is fixedly mounted on the machine frame along a first direction, the second drive member 65 is fixedly mounted on the support frame, and the push plate 64 is slidably mounted on the support frame. The second drive member 65 is driveably connected to the push plate 64, and the second drive member 65 can drive the push plate 64 to move in the opposite direction to the first direction to push the shaped material tube 100 and the mandrel 3 out of the tapered mold 1. In this embodiment, the second drive member 65 is a hydraulic cylinder. The piston rod of the second drive member 65 is connected to the push plate 64. By controlling the extension of the piston rod of the second drive member 65, the push plate 64 can be driven to move in the opposite direction to the first direction, thereby acting on the shaped material tube 100. The second drive member 65 cooperates with the first drive member 2 to eject the material tube 100 and the mandrel 3 from the tapered mold 1. In this way, the friction between the material tube 100 and the tapered mold 1 can be effectively overcome, thereby successfully completing the ejection action. In other embodiments, the second drive unit 65 may also be a cylinder or an electric cylinder, or a gear and rack structure or a lead screw and nut structure, without further restrictions.

[0043] In some embodiments, the support frame includes a base plate 61 and a top plate 62 spaced apart from each other. A second guide post 63 is provided between the base plate 61 and the top plate 62, extending along a first direction and connected to both the base plate 61 and the top plate 62. A push plate 64 is sleeved on the second guide post 63. A tapered mold 1 is fixedly inserted into a mounting hole in the base plate 61, which is fixedly mounted on the frame. A second drive member 65 is fixedly mounted on the top plate 62. By setting the base plate 61, the tapered mold 1 is easily fixed, allowing the shaped material tube 100 and mandrel 3 to enter the support frame. Then, the second drive member 65 drives the push plate 64 to move, completing the material ejection action in cooperation with the first drive member 2. The push plate 64, in cooperation with the second guide post 63, ensures that the push plate 64 moves linearly in the opposite direction of the first direction, thereby effectively pushing the material tube 100 to perform the material ejection action.

[0044] In some embodiments, the pipe taper extraction processing device further includes a support 7, on which the top plate 62 is supported. By providing the support 7, the top plate 62 can be supported, thereby effectively supporting the material unloading mechanism 6 and ensuring its stability.

[0045] In some embodiments, a limiting block 611 is fixedly provided on the side of the base plate 61 facing the top plate 62. By providing the limiting block 611, a mechanical limiting function can be achieved to limit the stroke of the push plate 64 and prevent the push plate 64 from colliding with the base plate 61 or the tapered mold 1.

[0046] In some embodiments, a third linear bearing 641 is fixedly disposed on the push plate 64, and the third linear bearing 641 is sleeved on the second guide post 63. By providing the third linear bearing 641, the friction between the push plate 64 and the second guide post 63 can be reduced, thereby ensuring that the push plate 64 moves smoothly relative to the second guide post 63.
