[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] like Figure 1-4As shown, a silicone rubber corrugated pipe molding injection port shearing machine includes a frame 10 with a shearing zone 11, a lower fixture 21 set in the shearing zone 11, a lifting seat 31 located above the lower fixture 21, an upper fixture 32, a Z-axis drive device 33 for driving the lifting seat 31 to rise and fall, a translation seat 41, an X-axis drive device 50 for driving the translation seat 41 to move in the left and right direction, and two Y-axis drive devices 60 respectively placed on the front and rear sides of the shearing zone 11 and installed on the translation seat 41; each Y-axis drive device 60 is connected to an automatic shear 71, and the automatic shear 71 is driven to move in the front and rear direction through the Y-axis drive device 60; the upper fixture 32 is fixed on the lifting seat 31 and cooperates with the lower fixture 21 to form a fixing device for fixing the silicone rubber corrugated pipe.
[0024] In use, the silicone rubber corrugated tube can be placed on the lower fixture 21, and the upper fixture 32 is lowered by the Z-axis drive device 33 to cooperate with the lower fixture 21, fixing the silicone rubber corrugated tube and preventing displacement during the shearing process. Then, the X-axis drive device 50 drives the translation seat 41 to move, so that each automatic shear 71 and the Y-axis drive device 60 move with the translation seat 41 to the corresponding injection port position. Then, the two Y-axis drive devices 60 drive the automatic shear 71 to move towards the shearing area 11. The automatic shear 71 connected by the two Y-axis drive devices 60 can simultaneously cut the injection port of the silicone rubber corrugated tube. Therefore, the silicone rubber corrugated tube forming injection port shearing machine provided by the present invention adopts a frame 10, a lower fixture 21, a lifting seat 31, an upper fixture 32, a Z-axis drive device 33, a translation seat 41, and an X-axis drive device 50. The combination of the Y-axis drive device 60 and the automatic shears 71 enables the cutting of the injection port, eliminating the need for manual rough cutting at the molding stage and manual fine cutting at the subsequent stage. This saves time, improves efficiency, reduces manual intervention, and lowers labor costs. Furthermore, by arranging the Y-axis drive devices 60 on both sides of the cutting zone 11, the automatic shears 71 connected to these two Y-axis drive devices 60 can simultaneously cut the injection port. Compared to a structure with the Y-axis drive device 60 on only one side of the cutting zone 11, this further saves time and improves efficiency. It also simplifies the movement trajectory of the automatic shears 71 and the structure of the Y-axis drive device 60. In addition, during each processing step, the automatic shears 71 can be moved to a predetermined position by the X-axis drive device 50 and the Y-axis drive device 60 for cutting, ensuring the consistency of injection port cutting for each product and improving product quality. In addition, in practical use, the silicone rubber corrugated pipe molding injection port shearing machine can also be used in conjunction with the product molding and vulcanization cycle. During the product molding and vulcanization process, the injection port of the previous molded product can be cut by the silicone rubber corrugated pipe molding injection port shearing machine, thereby increasing production capacity.
[0025] The Y-axis drive device 60 includes a drive component 61, a Y-axis lead screw nut 62, and a Y-axis bearing seat 63 movably mounted on a translation seat 41. The drive component 61 includes a Y-axis lead screw extending in the front-back direction and a rotary drive body for rotating the Y-axis lead screw. The Y-axis lead screw nut 62 is fitted onto the Y-axis lead screw and fixedly connected to the Y-axis bearing seat 63. The automatic shears 71 are connected to the Y-axis bearing seat 63. In use, the rotation of the Y-axis lead screw drives the Y-axis lead screw nut 62, along with the Y-axis bearing seat 63, to move along the extension direction of the Y-axis lead screw, thereby driving the automatic shears 71 to move in the front-back direction. By adopting the above structure, the automatic shears 71 can be driven to move in the front-back direction while improving the accuracy of the front-back movement of the automatic shears 71.
[0026] Preferably, the driving component 61 is a lead screw stepper motor, which can save assembly time.
[0027] The translation seat 41 is provided with a Y-axis guide rail 42 extending in the front-back direction, and the Y-axis bearing seat 63 is provided with a Y-axis moving block 64 that moves and cooperates with the Y-axis guide rail 42 and can move along the Y-axis guide rail 42, so that the Y-axis bearing seat 63 can be movably installed on the translation seat 41 and the Y-axis bearing seat 63 can move relatively smoothly.
[0028] Preferably, the Y-axis bearing seat 63 includes a longitudinal plate extending along the height direction of the frame 10 and a transverse plate disposed at the lower end of the longitudinal plate and extending in the horizontal direction. The Y-axis moving block 64 is fixed to the transverse plate, and the automatic shears 71 is fixed to the longitudinal plate. By adopting the above structure, the material used in the Y-axis bearing seat 63 can be reduced, the cost can be reduced, and the weight can be reduced, thus reducing the load on the translation seat 41.
[0029] The automatic shears 71 in the silicone rubber corrugated pipe molding injection port shearing machine can be pneumatic or electric shears, as long as they can be used to cut the injection port.
[0030] The frame 10 is provided with a support base 12, and the area above the support base 12 forms a shearing zone 11. The lower fixture 21 is fixed on the support base 12. The frame 10 forms a movable cavity 13 located below the support base 12. The translation seat 41 passes through the movable cavity 13, and the front and rear ends of the translation seat 41 extend out of the movable cavity 13 respectively. The two Y-axis drive devices 60 are respectively installed at the front and rear ends of the translation seat 41, so that the two Y-axis drive devices 60 are placed on the front and rear sides of the shearing zone 11, and the space can be fully utilized. Specifically, the frame 10 also includes a base 15 located below the support 12. A left wall is provided between the left end of the base 15 and the support 12, and a right wall is provided between the right end of the base 15 and the support 12. The X-axis drive device 50 is mounted on the base 15. The base 15, the left wall, the support 12, and the right wall form the movable cavity 13, thereby facilitating the formation of the movable cavity 13.
[0031] The X-axis drive device 50 includes an X-axis lead screw 51 that passes through the movable cavity 13 and extends in the left-right direction, a rotary drive component 80 for driving the X-axis lead screw 51 to rotate, and an X-axis lead screw nut 53 that is matched and sleeved on the X-axis lead screw 51. The translation seat 41 is movably mounted on the frame 10, and the X-axis lead screw nut 53 is fixedly connected to the translation seat 41. In use, the rotary drive component 80 drives the X-axis lead screw 51 to rotate, thereby driving the X-axis lead screw nut 53 and the translation seat 41 to move in the left-right direction. By adopting the above structure for the X-axis drive device 50, the translation seat 41 can be moved in the left-right direction while improving the accuracy of the translation seat 41's movement.
[0032] The X-axis lead screw 51 is rotatably mounted on the frame 10. The rotary drive component 80 includes a driven pulley 81, a driving pulley 82, a drive motor for driving the driving pulley 82 to rotate, and a synchronous belt 84, all fixed to the X-axis lead screw 51. The synchronous belt 84 is wound around the driving pulley 82 and the driven pulley 81. In use, the drive motor operates, driving the driving pulley 82 to rotate, which in turn drives the driven pulley 81 to rotate via the synchronous belt 84, thereby driving the X-axis lead screw 51 to rotate. By adopting the above structure for the rotary drive component 80, the X-axis lead screw 51 can be driven to rotate, and the positions of the X-axis lead screw 51 and the drive motor can be easily and reasonably set.
[0033] Specifically, the body of the drive motor is fixed to the base 15, a left bearing is fixed on the left wall, a right bearing is fixed on the right wall, the left end of the X-axis lead screw 51 is fixedly inserted into the inner ring of the left bearing, and the right end is fixedly inserted into the inner ring of the right bearing, thereby improving the smoothness of the rotation of the X-axis lead screw 51.
[0034] The frame 10 is provided with two X-axis guide rails 14 extending in the left-right direction and positioned on the front and rear sides of the X-axis lead screw 51. The translation seat 41 is provided with two X-axis moving blocks 43, which correspond one-to-one with the two X-axis guide rails 14 and can move along the extension direction of the X-axis guide rails 14. By adopting the above structure, the smoothness of the movement of the translation seat 41 can be improved.
[0035] The Z-axis drive device 33 includes a cylinder whose cylinder body is fixed on the frame 10. The lifting seat 31 is connected to the piston rod of the cylinder, so that the lifting seat 31 can be raised and lowered by the movement of the piston rod of the cylinder. Preferably, the frame 10 includes a top seat 16 located above the support seat 12. The top seat 16 is connected to the support seat 12 through a support rod 17. The lifting seat 31 is provided with a linear bearing, and the support rod 17 is inserted into the linear bearing, thereby improving the stability of the lifting seat 31 during lifting.
[0036] In this embodiment, the cylinder is an adjustable stroke cylinder. Of course, other existing cylinders can also be used, as long as they can drive the lifting seat 31 to rise and fall.
[0037] The shearing zone 11 is provided with at least two lower fixtures 21 arranged sequentially in the left-right direction. The silicone rubber corrugated pipe forming injection port shearing machine includes at least two upper fixtures 32 that correspond one-to-one with the at least two lower fixtures 21 and are fixed on the lifting seat 31. Each upper fixture 32 and the corresponding lower fixture 21 cooperate to form a fixing device, so that at least two silicone rubber corrugated pipes can be fixed through the at least two fixing devices, thereby facilitating the shearing of the injection port of at least two silicone rubber corrugated pipes, ensuring quality while achieving optimal production efficiency.
[0038] Preferably, the upper fixture 32 and the lower fixture 21 form a positioning cavity for positioning the silicone rubber corrugated tube. Openings 22 are provided at both ends of the positioning cavity. Positioning grooves 23 are formed at the corresponding openings 22 at both ends of the fixing device. The positioning grooves 23 communicate with the positioning cavity through the corresponding openings 22. In use, the injection port of the silicone rubber corrugated tube can extend through the openings 22, and the automatic shears 71 can enter the positioning grooves 23 to cut the injection port. The limiting effect of the groove walls of the positioning grooves 23 enables precise cutting, resulting in shallower and flatter cut edges, further improving the consistency of the injection port cutting. Specifically, the positioning grooves 23 penetrate the top and bottom of the fixing device, facilitating processing. Outer protrusions 24 are provided at both ends of the positioning grooves 23. Each outer protrusion 24 includes an upper outer protrusion on the upper fixture 32 and a lower outer protrusion on the lower fixture 21 aligned with the upper outer protrusion.
[0039] In actual design, in order to further optimize performance, the silicone rubber corrugated pipe molding injection port shearing machine can also adopt a control device, which can control the operation of the lead screw through stepper motor and drive motor, thereby intelligently controlling the movement path of the electric shears and making it more convenient to use.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
