[0002] The suction flute is the leading part of the suction device of the spinning frame. Its function is to suck the broken ends or flying cotton and introduce them into the main air duct through the suction branch pipe. The suction flute is made of two different processes and materials:

[0003] One is made of galvanized iron sheet, which is welded to the cotton suction pipe mouth through folding and biting, and the surface is painted;

[0004] The other method is to use aluminum alloy to heat-draw the air suction port and the cotton suction tube, weld the two together, and then oxidize the outer surface.

[0005] After the air suction port and the cotton suction tube are hot-drawn by aluminum alloy, a punching device is required to perform hole drilling operation on the cotton suction tube, wherein the holes to be drilled include connecting holes connected to the air suction port and the cotton suction port. Since the cross-sectional shape of the cotton suction tube is similar to the shape of a water drop, conventional punching dies cannot match the shape of the cotton suction tube well, resulting in the inability of conventional punching devices to achieve efficient punching operation of the cotton suction tube. Based on this, a punching device for processing cotton suction flute tubes is provided. Utility Model Content

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a punching device for the processing of a cotton suction pipe includes a punching assembly 1 having a workbench 101. In the middle of the top of the workbench 101, a U-shaped seat 102 is fixedly connected. Suction port punching grooves 103 and connection hole punching grooves 104 are respectively opened on both sides of the U-shaped seat 102. Punching hydraulic cylinders 105 and punching heads 106 are installed on both sides of the U-shaped seat 102 on the top of the workbench 101. The punching head 106 is fixed to the output end of the punching hydraulic cylinder 105, and the two punching heads 106 respectively match the suction port punching groove 103 and the connection hole punching groove 104 and are respectively inserted into the inner sides of the suction port punching groove 103 and the connection hole punching groove 104.

[0033] An inner support mold 107 is fixedly installed inside the U-shaped seat 102. A socket groove for inserting the punching head 106 is formed on the inner support mold 107 for sleeving the cotton suction pipe 2 and forming an inner wall support for the cotton suction pipe 2.

[0034] The punching operation of the cotton suction pipe 2 is realized by sequentially operating the punching hydraulic cylinder 105 to drive the punching head 106 to move.

[0035] A cavity groove 108 is opened at a position corresponding to the socket groove inside the inner support mold 107. The cavity groove 108 penetrates to the bottom of the inner support mold 107. A blanking groove 109 is opened on the top of the workbench 101 inside the U-shaped seat 102. The blanking groove 109 penetrates to the bottom of the workbench 101. The cavity groove 108 and the blanking groove 109 are used for the blanking of punching debris.

[0036] A limiting component 3 is arranged at the front end of the workbench 101. The limiting component 3 is used to provide clamping and limiting for the cotton suction pipe 2 sleeved outside the inner support mold 107.

[0037] The outer wall shape of the inner support mold 107 is in a water droplet shape and matches the inner wall shape of the cotton suction pipe 2, and the length of the inner support mold 107 matches the length of the cotton suction pipe 2.

[0038] The number of punching hydraulic cylinders 105 corresponding to the punching head 106 is multiple, and the multiple punching hydraulic cylinders 105 are evenly distributed in the horizontal direction.

[0039] In this embodiment: when punching the cotton suction pipe 2, the operation steps are as follows:

[0040] Horizontally sleeved the cotton suction pipe 2 to be punched on the outside of the inner support mold 107, making one end of the cotton suction pipe 2 fit against the inner wall end face of the U-shaped seat 102. Then, the limiting component 3 was made to fit against the front end of the inner support mold 107 and the cotton suction pipe 2, thus realizing the clamping and fixing of the cotton suction pipe 2. After that, the punching hydraulic cylinder 105 was started. The punching hydraulic cylinder 105 drove the punching head 106 to move towards the inside of the U-shaped seat 102 and finally contacted the cotton suction pipe 2 to realize the punching operation on the cotton suction pipe 2. The debris generated by punching was temporarily accumulated inside the cavity groove 108 (it should be noted that: the punching hydraulic cylinders 105 corresponding to the two punching heads 106 operated in batches. For example: the punching head 106 corresponding to the cotton suction port first punched the cotton suction pipe 2, and after the punching head 106 corresponding to the cotton suction port was reset, the punching head 106 corresponding to the connection hole punched the cotton suction pipe 2 again);

[0041] After that, the punching hydraulic cylinder 105 reset and drove the punching head 106 to reset, making the punching head 106 retract into the U-shaped seat 102, so that it would not interfere with the disassembly and assembly of the cotton suction pipe 2;

[0042] Then, the limit of the limiting component 3 on the cotton suction pipe 2 was released. At this time, the cotton suction pipe 2 could be disassembled. The debris inside the cavity groove 108 lost the bottom support and would fall through the cavity groove 108 and the blanking groove 109;

[0043] Through the cooperation of the above-mentioned multiple parts, the rapid punching operation on the water-drop-shaped cotton suction pipe 2 could be realized.

[0044] Please refer specifically to Figures 1 to 4 , the limiting component 3 includes a clamping unit and a driving unit. The driving unit is used to provide the driving force for the movement and rotation of the clamping unit. The clamping unit moves to fit against one end of the inner support mold 107 to realize the clamping and limiting of the cotton suction pipe 2;

[0045] The clamping unit includes a fixed arm 301, a moving rail groove 303, and a limiting plate 304;

[0046] The two fixed arms 301 are fixed at one end of the workbench 101 and are symmetrically distributed with the blanking groove 109 as the center. The moving rail groove 303 is opened on one side of the fixed arm 301 and runs through to the other side of the fixed arm 301;

[0047] The limiting plate 304 is distributed between the two fixed arms 301, and the bottom of both sides of the limiting plate 304 is fixedly connected with a rotating shaft that is slidably connected to the inner wall of the moving rail groove 303. By rotating the limiting plate 304 to the vertical state and fitting it against the end face of the inner support mold 107, it is used to realize the clamping and limiting of the cotton suction pipe 2;

[0048] The driving unit includes a fixed plate 302, a transmission gear 305, a fixed tooth arm 306, an L-shaped connecting arm 307, a moving plate 308, and a limit hydraulic cylinder 309;

[0049] The fixed plate 302 is fixed to the bottom of one end of the two fixed arms 301 away from the workbench 101. The transmission gears 305 are symmetrically fixed on both sides of the rotating shaft connected to the limit plate 304. The fixed tooth arm 306 is fixed to the bottom of the workbench 101 and extends below the transmission gear 305 and meshes with the transmission gear 305;

[0050] The L-shaped connecting arms 307 are symmetrically distributed on the mutually remote sides of the two fixed arms 301 and are rotatably connected to the connected rotating shaft;

[0051] The moving plate 308 is fixed to one end of the horizontal part of the L-shaped connecting arm 307. The limit hydraulic cylinder 309 is fixedly installed at one end of the fixed plate 302, and the output end of the limit hydraulic cylinder 309 is fixedly connected to the moving plate 308;

[0052] By operating the limit hydraulic cylinder 309, the rotation and movement operations of the limit plate 304 can be realized, so as to realize that the limit plate 304 moves away from the inner support mold 107 and rotates to the horizontal state, so as to facilitate the installation and disassembly of the cotton suction pipe 2.

[0053] In this embodiment: when the cotton suction pipe 2 is sleeved on the outside of the inner support mold 107, the limit hydraulic cylinder 309 is started. The limit hydraulic cylinder 309 pushes the moving plate 308 to move towards the workbench 101. The moving plate 308 drives the limit plate 304 and the transmission gear 305 to move synchronously through the L-shaped connecting arm 307. Due to the limitation of the fixed tooth arm 306 on the transmission gear 305, the transmission gear 305 rotates while moving horizontally. In this way, while the limit plate 304 moves, it rotates from the horizontal state to the vertical state, and the limit plate 304 in the vertical state fits the end faces of the inner support mold 107 and the cotton suction pipe 2, thereby realizing the limit fixation of the cotton suction pipe 2;

[0054] Through the cooperation of the above-mentioned multiple parts, the cotton suction pipe 2 can be kept stable and immovable during punching, so as to avoid the situation of punching misalignment;

[0055] When it is necessary to disassemble the cotton suction pipe 2, only the limit hydraulic cylinder 309 needs to be operated to reset.

[0056] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
