Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of die-shrink tube production, specifically to a post-processing device for die-shrink tube production. Background Technology
[0002] Tube reduction molding is a pipe processing technology that uses molds to reduce the diameter of pipes to meet specific dimensional requirements. Simply put, it involves taking a pipe with a larger diameter and using specific molds and processes to reduce its diameter to the required size while ensuring other performance and quality requirements are met.
[0003] Traditional cooling devices are often fixed on the production line, making it impossible to move and rewind the pipes simultaneously during the cooling process. This results in the need for additional steps to rewind the pipes after cooling, increasing the complexity and time cost of the production process. For example, in some production lines, the pipes need to be manually moved to the rewinding equipment after cooling, which is not only inefficient but also prone to damaging the pipes during handling. Utility Model Content
[0004] The purpose of this invention is to provide a post-processing device for die-shrink tube production to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a post-processing device for die-shrink tube production, comprising a take-up roller, a processing box body, and a baffle. A feed hole is provided on one outer end face of the processing box body, and air inlets are provided on both outer end faces of the processing box body. A filter plate is welded to the inner wall of the processing box body, and a take-up roller is rotatably connected to the inner wall of the processing box body. A baffle is fixed on one outer end face of the take-up roller, and a fixing groove is provided on the upper surface of the take-up roller.
[0006] When using the post-processing device for shrink tube production in this technical solution, the shrink tube is inserted into the processing box body through the feed hole. The hydraulic cylinder inside the outer rod drives the hydraulic rod to move, the hydraulic rod drives the clamping plate to move, and the clamping plate drives the groove to move. The clamping plate can clamp the shrink tube. The groove design of the clamping plate can closely fit the outer surface of the shrink tube or other materials, providing a stable clamping force. This clamping method can not only ensure the stability of the shrink tube during the processing, but also avoid damage to the surface of the tube due to excessive clamping force. With precise control of the hydraulic cylinder, the clamping plate can accurately clamp the die-shrink tube, providing reliable support for subsequent processing operations. One end of the die-shrink tube is inserted into the fixed groove, and the hydraulic cylinder inside the outer plate drives the hydraulic rod to move. The hydraulic rod drives the inner plate to move, and the inner plate can clamp the die-shrink tube, fixing one end of the die-shrink tube to the inner wall of the take-up roller. A motor is set on one side of the take-up roller, and the motor drives the take-up roller to rotate. The take-up roller can take up the die-shrink tube. The baffle can prevent the die-shrink tube from falling off the outer surface of the take-up roller. The design of the baffle must take into account the take-up diameter and shape of the die-shrink tube to provide sufficient protection, while ensuring that it does not affect the normal rotation of the take-up roller.
[0007] Preferably, a workbench is welded to the lower surface of the processing box body, and a support leg is welded to the lower surface of the workbench. A sealing cover is hinged to the upper surface of the processing box body, and a handle is welded to the upper surface of the sealing cover. The processing box body, workbench, and support leg are connected together by welding to form a highly integrated structure.
[0008] Preferably, a fan is installed at the bottom of the interior of the processing box body, and a blower shroud is connected to the upper surface of the fan. The connection between the fan and the blower shroud makes the entire cooling system more integrated, reduces external connecting parts, lowers the risk of failure due to loose or damaged connecting parts, and improves the reliability and ease of maintenance of the equipment.
[0009] Preferably, an outer rod is fixed to the top of the inner part of the processing box body and the upper surface of the filter plate, and an inner rod is movably inserted into one side of the outer end face of the outer rod. Through this movable insertion, the inner rod can move up and down within the outer rod, thereby achieving height adjustment. This design allows for flexible adjustment of the inner rod's position according to the needs of different heights of molded tubes or other materials, enabling it to adapt to materials of different sizes and increasing the equipment's versatility and applicability.
[0010] Preferably, a clamping plate is fixed to one outer end face of the inner rod, and the clamping plate has a groove inside. The groove design of the clamping plate can closely fit the outer surface of the molded tube or other materials, providing a stable clamping force. This design can ensure that the tube will not loosen or slip due to external forces during the processing, thereby ensuring the stability and reliability of the processing.
[0011] Preferably, an outer plate is fixed to the inner wall of the fixing groove, and an inner plate is movably inserted into one outer end face of the outer plate. Through this movable insertion, the inner plate can extend, retract, or move within the outer plate, thereby adjusting its size. This design allows for flexible adjustment of the inner plate's position according to the requirements of different specifications of molded tubes or other materials, enabling it to adapt to materials of different sizes and increasing the equipment's versatility and applicability.
[0012] Preferably, hydraulic cylinders are installed on the inner walls of both the outer plate and the outer rod, and a hydraulic rod is movably inserted into one outer end face of the hydraulic cylinder, the hydraulic rod being connected to the inner plate and the inner rod. The combination of the hydraulic cylinder and the hydraulic rod enables precise position control. Through the hydraulic system, the extension and retraction length of the hydraulic rod can be precisely adjusted, thereby achieving precise position adjustment of the inner plate and the inner rod. This precise control capability is particularly important for the production of molded tubes requiring high-precision machining, ensuring the positional accuracy of the tube during processing.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model achieves the effect of facilitating the winding of the die-shrink tube by setting an outer rod, an outer plate, and an inner plate. The die-shrink tube is inserted into the processing box body through the feed hole. The hydraulic cylinder inside the outer rod drives the hydraulic rod to move, the hydraulic rod drives the clamping plate to move, and the clamping plate drives the groove to move. The clamping plate can clamp the die-shrink tube. The groove design of the clamping plate can closely fit the outer surface of the die-shrink tube or other materials, providing a stable clamping force. This clamping method can not only ensure the stability of the die-shrink tube during the processing, but also avoid damage to the surface of the tube due to excessive clamping force. With precise control of the hydraulic cylinder, the clamping plate can accurately clamp the die-shrink tube, providing reliable support for subsequent processing operations. One end of the die-shrink tube is inserted into the fixed groove, and the hydraulic cylinder inside the outer plate drives the hydraulic rod to move. The hydraulic rod drives the inner plate to move, and the inner plate can clamp the die-shrink tube, fixing one end of the die-shrink tube to the inner wall of the take-up roller. A motor is set on one side of the take-up roller, and the motor drives the take-up roller to rotate. The take-up roller can take up the die-shrink tube. The baffle can prevent the die-shrink tube from falling off the outer surface of the take-up roller. The design of the baffle must take into account the take-up diameter and shape of the die-shrink tube to provide sufficient protection, while ensuring that it does not affect the normal rotation of the take-up roller.
[0015] 2. This utility model improves cooling efficiency and quality by incorporating a fan, a blower hood, and air inlets. The fan blows cold air through the blower hood, which then passes through a filter plate and enters the top of the processing chamber. This design ensures that the air blown by the fan is evenly distributed on the surface of the molded tube, achieving a highly efficient cooling effect. The blower hood design ensures uniform air distribution, avoiding problems of localized excessively fast or slow cooling, thus improving cooling efficiency and quality. Air inlets are provided on both outer ends of the processing chamber, allowing external air to be introduced, increasing airflow, and further enhancing the cooling effect. Simultaneously, the air inlets design also helps reduce the internal air pressure of the processing chamber, preventing excessively high air pressure from affecting the cooling effect. A workbench is welded to the lower surface of the processing chamber, and support legs are welded to the lower surface of the workbench. This welding structure provides extremely high stability, ensuring that the entire device will not shake or tip over during operation. The welded connections are firm, capable of withstanding significant weight and pressure, extending the service life of the equipment. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Please see Figures 1 to 4This utility model provides an embodiment of a post-processing device for die-shrunk tube production, comprising a take-up roller 3, a processing box body 9, and a baffle 16. An outer rod 12 is fixed to the top of the inner end of the processing box body 9 and the upper surface of the filter plate 5. An inner rod 15 is movably inserted into one side of the outer end face of the outer rod 12. A clamping plate 13 is fixed to one side of the outer end face of the inner rod 15, and a groove 14 is provided inside the clamping plate 13. The take-up roller 3 is rotatably connected to the inner wall of the processing box body 9. A baffle 16 is fixed to one side of the outer end face of the take-up roller 3, and a fixing groove 21 is provided on the upper surface of the take-up roller 3. An outer plate 20 is fixed to the inner wall of the fixing groove 21, and an inner plate 19 is movably inserted into one side of the outer end face of the outer plate 20. Hydraulic cylinders 17 are installed on the inner walls of both the outer plate 20 and the outer rod 12, and a hydraulic rod 18 is movably inserted into one side of the outer end face of the hydraulic cylinder 17. The hydraulic rod 18 is connected to the inner plate 19 and the inner rod 15.
[0024] Of course, as is well known to those skilled in the art, the hydraulic cylinder 17 of this utility model also needs to be provided with a power device to enable it to work normally. And as is well known to those skilled in the art, the provision of such power is commonplace and is a conventional means or common knowledge. It will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.
[0025] According to Embodiment 1, a post-processing device for molded tube production involves inserting the molded tube into the processing box body 9 through the feed hole 4. The hydraulic cylinder 17 inside the outer rod 12 drives the hydraulic rod 18 to move, which in turn drives the clamping plate 13 to move. The clamping plate 13 then drives the groove 14 to move, allowing the clamping plate 13 to clamp the molded tube. The groove 14 of the clamping plate 13 is designed to closely fit the outer surface of the molded tube or other materials, providing a stable clamping force. This clamping method not only ensures the stability of the molded tube during processing but also avoids damage to the tube surface due to excessive clamping force. With precise control of the hydraulic cylinder 17, the clamping plate 13 can accurately clamp the mold shrink tube, providing reliable support for subsequent processing operations. One end of the mold shrink tube is inserted into the fixed groove 21. The hydraulic cylinder 17 inside the outer plate 20 drives the hydraulic rod 18 to move, and the hydraulic rod 18 drives the inner plate 19 to move. The inner plate 19 can clamp the mold shrink tube and fix one end of the mold shrink tube to the inner wall of the take-up roller 3. A motor is provided on one side of the take-up roller 3. The motor drives the take-up roller 3 to rotate, and the take-up roller 3 can take up the mold shrink tube. The baffle 16 can prevent the mold shrink tube from falling off the outer surface of the take-up roller 3. The design of the baffle 16 should take into account the take-up diameter and shape of the mold shrink tube to provide sufficient protection, while ensuring that it does not affect the normal rotation of the take-up roller 3.
[0026] Example 2
[0027] like Figures 1-4As shown, the post-processing device for die-shrink tube production proposed in this utility model, compared with Embodiment 1, further includes a winding roller 3, a processing box body 9, and a baffle 16. A workbench 10 is welded to the lower surface of the processing box body 9, and a support leg 11 is welded to the lower surface of the workbench 10. A sealing cover 2 is hinged to the upper surface of the processing box body 9, and a handle 1 is welded to the upper surface of the sealing cover 2. A feed hole 4 is opened on one outer end face of the processing box body 9, and air inlets 6 are opened on both outer end faces of the processing box body 9. A fan 8 is installed at the bottom of the interior of the processing box body 9, and a blower hood 7 is connected to the upper surface of the fan 8. A filter plate 5 is welded to the inner wall of the processing box body 9.
[0028] In this embodiment, the fan 8 blows cold air through the blower hood 7, and the cold air is blown into the top of the processing box body 9 through the filter plate 5. This design allows the air blown by the fan 8 to be evenly distributed on the surface of the molded tube, achieving a highly efficient cooling effect. The design of the blower hood 7 ensures uniform air distribution, avoids the problem of localized cooling being too fast or too slow, and improves cooling efficiency and quality. Air inlets 6 are provided on both outer end faces of the processing box body 9. These air inlets 6 can introduce external air, increase air circulation, and further improve the cooling effect. At the same time, the design of the air inlets 6 also helps to reduce the air pressure inside the processing box body 9, avoiding the cooling effect being affected by excessive air pressure. A workbench 10 is welded to the lower surface of the processing box body 9, and a support leg 11 is welded to the lower surface of the workbench 10. This welding structure provides extremely high stability, ensuring that the entire device will not shake or tip over during operation. The welded connection is firm and can withstand greater weight and pressure, extending the service life of the equipment.
