Description

Technical Field

[0001] This utility model relates to the technical field of press-fit tube end forming machine, specifically a press-fit tube end forming machine that is easy to change molds. Background Technology

[0002] Pipe end forming machines are industrial processing equipment used to flare, shrink, or reduce the diameter of pipe fittings. In existing technology, clamping pipe end forming machines typically refer to forming equipment that applies force from top to bottom or bottom to top to process the pipe end after the material's displacement is restricted by a clamping or positioning mechanism.

[0003] Existing press-fit pipe end forming machines typically require molds of different sizes to accommodate workpieces of different standards. These molds are usually mounted on the machine surface with multiple sets of bolts, requiring specialized tools for removal, which is a cumbersome process. To address this issue, we propose a press-fit pipe end forming machine that facilitates mold replacement. Utility Model Content

[0004] The purpose of this invention is to provide a clamping tube end forming machine that facilitates mold replacement, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping-type pipe end forming machine that facilitates mold replacement, comprising a machine base and a mold. A protective frame is fixedly installed on the top of the machine base, and an electric push rod is provided on the inner wall of the protective frame. A clamping plate is fixedly installed on the side of the electric push rod. A fixing frame is fixedly installed on the back of the machine base, and an electric push rod is provided on the inner wall of the fixing frame. A pressure plate is fixedly installed at the bottom of the electric push rod. A fixing block is fixedly installed at the bottom of the mold, and a slot is provided in the fixing block. A control component and a driven component are provided inside the machine base. The control component includes: The clamping block has a trapezoidal cross-section. The side of the clamping block fits against the inner wall of the support block. A support rod is fixedly installed on the inner wall of the support block. The support rod passes through the clamping block and is slidably connected to the clamping block. The side of the support block is provided with a fixing element to restrict the fixing block, thereby releasing the restriction on the fixing block and the mold, achieving the purpose of quick mold removal, and avoiding the difficulty of removal due to the need to use professional tools.

[0006] Preferably, the fixing component includes a spring, one end of which is fixedly installed on the outer wall of the support rod, and the other end of which is fixedly installed on the side of the locking block. When the cut surface of the locking block is in contact with the support rod, it can slide along the surface of the support rod, and when it is no longer in contact with the support rod, it bounces up under the action of the spring.

[0007] Preferably, the side of the support block is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly installed on the inner wall of the machine tool. When the support block is no longer under force, it can spring up from inside the machine tool under the action of the second spring.

[0008] Preferably, a sliding rod is fixedly installed on the side of the support block. The sliding rod passes through the machine base and is slidably connected to the machine base. When the sliding rod moves inside the machine base, the support block fixed to the surface of the sliding rod can move synchronously.

[0009] Preferably, a horizontal bar is fixedly installed on the inner wall of the machine tool. The horizontal bar passes through the slide bar and is slidably connected to the slide bar. The horizontal bar can ensure the stability of the slide bar during lateral movement.

[0010] Preferably, the driven component includes a protrusion, which is fixedly installed on the inner wall of the machine tool. The front end of the protrusion is arc-shaped, and the protrusion on the inner wall of the machine tool can limit the lateral rebound speed of the slide bar.

[0011] Preferably, a vertical rod is fixedly installed on the inner wall of the slider, the vertical rod passes through the slider and is slidably connected to the slider, the top of the slider is fixedly connected to one end of the spring three, and the other end of the spring three is fixedly installed on the outer wall of the vertical rod. When the cut surface of the slider is abutted, it can move longitudinally along the surface of the vertical rod.

[0012] Compared with the prior art, this utility model provides a clamping tube end forming machine that facilitates mold replacement, and has the following beneficial effects: 1. This easy-to-change mold-changing clamping tube end forming machine is equipped with a control component. By pushing a slide bar on the side of the machine, the slide bar slides along the surface of the flat bar. When the slide bar moves, the support block fixed on the surface of the slide bar can compress the second spring. When the support block moves, the clamping block connected to the support rod in the support block will be removed from the slot in the fixed block, thereby releasing the restriction on the fixed block and the mold, achieving the purpose of quick mold removal and avoiding the difficulty of removal caused by the need to use professional tools.

[0013] 2. This easy-to-change mold-changing clamping tube end forming machine is equipped with a driven component. When the support block is no longer under force, it can spring up under the action of spring two. When the support block and slide rod spring up, the protrusion fixed on the inner wall of the machine will abut against the tangential surface of the slide block. When the tangential surface of the slide block is abutted, it can move longitudinally on the surface of the vertical rod, thereby limiting the springing speed of the support block and slide rod, and avoiding the situation where the springing speed is too fast and the fixed block and mold are not removed in time, causing jamming with the fixed block.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: a clamping tube end forming machine that facilitates mold replacement, including a machine base 1 and a mold 10. A protective frame 2 is fixedly installed on the top of the machine base 1. An electric push rod 3 is provided on the inner wall of the protective frame 2. A clamping plate 4 is fixedly installed on the side of the electric push rod 3. A fixing frame 5 is fixedly installed on the back of the machine base 1. An electric push rod 6 is provided on the inner wall of the fixing frame 5. A pressure plate 7 is fixedly installed at the bottom of the electric push rod 6. A fixing block 11 is fixedly installed at the bottom of the mold 10. A slot 12 is opened in the fixing block 11. A control component 8 and a driven component 9 are provided in the machine base 1. The control component 8 includes: a clamping block 81, a support block 82, a support rod 83, and a fixing component 8. 4. The cross-sectional shape of the locking block 81 is trapezoidal. The side of the locking block 81 fits against the inner wall of the support block 82. The inner wall of the support block 82 is fixedly installed with a support rod 83. The support rod 83 passes through the locking block 81 and is slidably connected to the locking block 81. The side of the support block 82 is provided with a fixing member 84 to restrict the fixing block 11. When the support block 82 moves, it compresses the spring 842. At the same time, when the support block 82 moves, the locking block 81 connected to the support rod 83 in the support block 82 can be moved out from the slot 12 opened in the fixing block 11, thereby releasing the restriction on the fixing block 11 and the mold 10, achieving the purpose of quickly removing the mold 10 and avoiding the situation where it is difficult to remove due to the need to use professional tools.

[0017] The fixing component 84 includes a first spring 841, one end of which is fixedly mounted on the outer wall of the support rod 83, and the other end of which is fixedly mounted on the side of the locking block 81. When the cut surface of the locking block 81 is pressed against, it can slide along the surface of the support rod 83, and when it is no longer pressed, it springs up under the action of the first spring 841. The side of the support block 82 is fixedly connected to one end of a second spring 842, and the other end of the second spring 842 is fixedly mounted on the inner wall of the machine base 1. When the support block 82 is no longer under force, it can spring up from inside the machine base 1 under the action of the second spring 842. A sliding rod 843 is fixedly mounted on the side of the support block 82. The sliding rod 843 passes through the machine base 1 and is slidably connected to the machine base 1. When the sliding rod 843 moves inside the machine base 1, the support block 82 fixed to the surface of the sliding rod 843 can move synchronously. A horizontal rod 844 is fixedly installed on the inner wall of the machine base 1. The horizontal rod 844 passes through the slide rod 843 and is slidably connected to the slide rod 843. The horizontal rod 844 ensures the stability of the slide rod 843 during lateral movement. The driven component 9 includes a protrusion 91, which is fixedly installed on the inner wall of the machine base 1. The front end of the protrusion 91 is arc-shaped. The protrusion 91 on the inner wall of the machine base 1 can limit the lateral rebound speed of the slide rod 843. A vertical rod 92 is fixedly installed on the inner wall of the slide rod 843. The vertical rod 92 passes through the slider 93 and is slidably connected to the slider 93. The top of the slider 93 is fixedly connected to one end of the spring 94. The other end of the spring 94 is fixedly installed on the outer wall of the vertical rod 92. When the cut surface of the slider 93 is abutted, it can move longitudinally along the surface of the vertical rod 92.

[0018] In this invention, during use, the pipe to be processed is placed against the top of the mold 10. After placement, the electric push rod 3 is driven to move the clamping plate 4, which fixes the pipe. After fixing, the electric push rod 6 inside the fixing frame 5 pushes the pressure plate 7 downward to perform clamping processing on the pipe. When the mold 10 needs to be replaced, the slide rod 843 is pushed from the front of the machine base 1. The slide rod 843 drives the support block 82 to slide along the surface of the flat rod 844. When the support block 82 moves, it compresses the spring 842. At the same time, when the support block 82 moves, the locking block 81 connected to the support rod 83 inside the support block 82 can be removed from the slot 12 opened in the fixing block 11. After removal, the mold 10 and the fixing block 11 can be taken out from the machine base 1 for disassembly. When the force of pushing the slide rod 843 is released, the support block 82 fixed to the surface of the slide rod 843 can be removed from the slot 12 opened in the spring 844. When the slide bar 843 springs up, the protrusion 91 fixed to the inner wall of the machine base 1 will abut against the cross-section of the slider 93. When the cross-section of the slider 93 is abutted, it can move longitudinally on the surface of the vertical rod 92, thereby limiting the springing speed of the support block 82 and the slide bar 843, and avoiding the situation where the springing speed is too fast and the fixing block 11 and the mold 10 are not removed in time and jammed with the fixing block 11. Then, the new mold 10 and the fixing block 11 are inserted into the machine base 1. When the fixing block 11 is inserted into the machine base 1, it will abut against the cross-section of the locking block 81. When the cross-section of the locking block 81 is abutted, it can slide in the support block 82 under the action of the spring 841, and when it comes into contact with the slot 12 in the fixing block 11, it will spring up under the action of the spring 841 and jam into the slot 12 in the fixing block 11, thus limiting the removal of the fixing block 11 and the mold 10 and achieving the purpose of quick fixing.

[0019] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
