Description

Technical Field

[0001] The invention relates to the field of corrugated pipe processing equipment, in particular to a novel corrugated pipe forming machine. Background Art

[0002] As a pipe widely used in many fields, corrugated pipe plays a key role in the construction, machinery, chemical industry and other industries. With the continuous development of various industries, the performance requirements for corrugated pipes are also increasing, especially in terms of strength and support.

[0003] In traditional bellows forming technology, the bellows are usually manufactured by directly heat-combining the sheet and the metal wire in the mold and then winding them. However, this method has many disadvantages. On the one hand, due to process limitations, the tightness of the combination of the sheet and the metal wire is not ideal when they are heat-combined in the mold, resulting in limited strength and support of the final bellows, which is difficult to meet the use requirements of heavy-duty pipes. When subjected to greater pressure or external force, it is prone to deformation, rupture and other problems, affecting its application in some occasions with higher requirements for pipe performance.

[0004] On the other hand, the design of the cooling link of traditional molding machines is relatively simple, and often only one cooling is performed or the cooling effect is poor. During the molding process of the bellows, temperature changes have a significant impact on its quality. If the cooling is insufficient or uneven, it is easy to cause the internal structure of the bellows to be unstable, and local stress concentration will occur, thereby reducing the overall quality and stability of the product and increasing the defective rate.

[0005] In addition, traditional equipment lacks flexibility in adjusting the width of corrugated pipes. Different application scenarios require corrugated pipes of different specifications, and traditional equipment is difficult to quickly and accurately change the width of corrugated pipes. This requires manufacturers to frequently replace equipment or perform complex debugging when facing diverse market demands, greatly increasing production costs and production cycles, and reducing production efficiency.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0018] Please refer to the attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides a novel corrugated tube forming machine, such as Figure 1As shown, it includes a water reservoir 1. As an important component of the entire equipment, the water reservoir 1 is mainly used to store condensed water, etc., to provide water source support for the cooling system of the equipment. A wire reel 2 is set on one side of the water reservoir 1. The wire reel 2 is specially used for winding wires. The outer diameter of the wire reel is tightly wound with wires. These wires will play a key role in the subsequent bellows manufacturing process and provide enhanced structural strength for the bellows. A frame 3 is set on the other side of the water reservoir 1. The frame 3 serves as the supporting frame of the entire equipment and carries many parts to ensure that the relative positions of the various parts remain stable during the working process, providing a solid foundation for the normal operation of the equipment. A sheet forming mold 4 is fixedly installed on the top of the water reservoir 1 near the wire reel 2. The sheet forming die 4 is the key part for the initial combination of the sheet and the metal wire. It is precisely designed to enable the metal wire and the sheet extruded from the screw extruder 5 to be perfectly compounded. The screw extruder 5 is fixedly installed on the rear side of the sheet forming die 4. The output end of the screw extruder 5 accurately extends to the interior of the sheet forming die 4. Its main function is to squeeze the heated sheet into the sheet forming die 4 at a certain pressure and speed, thereby realizing the compounding process of the sheet and the metal wire. A cooling water tank 6 is fixedly installed directly above the water reservoir 1 through a bracket. The cooling water tank 6 occupies an important position in the cooling process of the entire equipment and is used for preliminary cooling of the sheet with the metal wire coming out of the sheet forming die 4. A fixing plate 15 is fixedly installed on the rear side of the inner part of the frame 3. The fixed plate 15 plays the role of stabilizing and positioning the bellows forming mold 16 to ensure that it can rotate stably during the working process. The bellows forming mold 16 is movably installed in the middle of the fixed plate 15. The bellows forming mold 16 is the core component of the bellows forming. The winding of the sheet is achieved by rotation to form the basic shape of the bellows. A lifting platform 18 is movably installed inside the frame 3. The lifting platform 18 can move in the vertical direction according to production requirements to provide a flexible height adjustment function for the entire bellows forming process. Guide rails 20 are fixedly installed on both sides of the upper surface of the lifting platform 18. The guide rails 20 provide precise guidance for the movement of the slide 21 to ensure the stability and accuracy of the slide 21 during movement. Slides are movably installed on both sides of the guide rails 20 The slide 21 can slide smoothly along the guide rail 20 to provide support for the position adjustment of the lower pressure roller 25. A positioning frame 22 is fixedly welded on the top of the slide 21 close to the side of the corrugated tube forming mold 16. The positioning frame 22 is used to accurately fix the positions of the movable shaft 24 and the lower pressure roller 25 to ensure their stability during the working process. The inner side of the top of the positioning frame 22 is movably installed with a movable shaft 24. The movable shaft 24 can rotate flexibly to drive the lower pressure roller 25 to rotate, thereby cooperating with the corrugated tube forming mold 16 to complete the winding of the corrugated tube. The outer diameter of the movable shaft 24 is fixedly installed with a lower pressure roller 25. The lower pressure roller 25 applies appropriate pressure during the winding process of the corrugated tube to ensure that the sheet can be tightly wound on the corrugated tube forming mold 16.A vertical cylinder 33 is fixedly installed on the top of the fixed plate 15. The vertical cylinder 33 can accurately control the vertical movement of the upper pressure roller 34 to provide additional pressure support for the winding of the corrugated tube. The upper pressure roller 34 is fixedly installed at the end of the vertical cylinder 33. Driven by the vertical cylinder 33, the upper pressure roller 34 descends and adheres to the top of the corrugated tube being wound, further improving the stability of the winding process. A hot glue gun 35 is fixedly installed on the inner upper side of the frame 3 close to the water reservoir 1. During the winding process of the corrugated tube, the hot glue gun 35 timely sprays hot glue to firmly stick the wound material sheets together, making the structure of the corrugated tube more stable. A cooling air duct 36 is fixedly installed on the inner upper side of the frame 3 away from the water reservoir 1, and the end of the cooling air duct 36 extends to one side of the corrugated tube forming mold 16. The cooling air duct 36 is used to air cool the preliminarily formed corrugated tube, further accelerate its cooling speed, and improve production efficiency and product quality.

[0019] In this embodiment, a plurality of condensation water pipes 7 are fixedly installed on the upper side of the cooling water trough 6 close to the sheet forming mold 4. The condensation water pipes 7 are responsible for introducing the condensation water into the cooling water trough 6 to perform the first cooling on the sheet with metal wire coming out of the sheet forming mold 4, ensuring that the sheet is preliminarily cooled before entering the subsequent process. A plurality of seepage holes 10 are opened on the bottom wall of the cooling water trough 6 close to the condensation water pipe 7. The function of these seepage holes 10 is to allow the cooled condensation water to smoothly fall into the water reservoir 1, so as to realize the recycling of the condensation water. Water-retaining cotton 11 is arranged on both sides of the interior of the cooling water trough 6. The water-retaining cotton 11 can form a left and right semi-closed structure in the middle section of the cooling water trough 6, effectively gathering the condensation water in the cooling water trough 6, thereby improving the cooling effect and ensuring that the sheet with metal wire can be fully cooled.

[0020] Furthermore, a drip pipe 8 is fixedly installed through a bracket just above the cooling water trough 6, and a plurality of drip valves 9 are evenly arranged at the bottom end of the drip pipe 8. The drip pipe 8 and the drip valve 9 together constitute a part of the secondary cooling system. Water droplets are slowly dripped onto the surface of the sheet through the drip valve 9, and the sheet with the metal wire that has been cooled once is subjected to secondary cooling, thereby further ensuring the cooling effect of the sheet. A circulating water pump 12 is fixedly installed inside the water reservoir 1, and the circulating water pump 12 is responsible for extracting the condensed water in the water reservoir 1 and pumping it into the drip pipe 8 through the return pipe 13, thereby realizing the recycling of the condensed water, saving water resources and ensuring the continuous and stable operation of the cooling system. A return pipe 13 is fixedly installed at the output end of the circulating water pump 12, and the end of the return pipe 13 is connected to the inside of the drip pipe 8. The return pipe 13 serves as a channel for conveying condensed water, and accurately conveys the condensed water extracted by the circulating water pump 12 to the drip pipe 8, thereby ensuring the normal operation of the secondary cooling system.

[0021] Furthermore, a first guide wheel group 14 is fixedly installed on one side of the top of the water reservoir 1 near the frame 3. The first guide wheel group 14 plays a role in guiding the direction of the metal wire, so that the metal wire can be smoothly pulled from the wire roller 2 to the subsequent processing parts, ensuring the stability and accuracy of the metal wire during the transmission process. A second guide wheel group 23 is movably installed on the outer side of the top of the positioning frame 22. The second guide wheel group 23 is also used to guide the direction of the metal wire and work together with the first guide wheel group 14 to ensure that the transmission path of the metal wire is smooth before entering the lower pressure roller 25, avoiding problems such as entanglement or deviation of the metal wire. A tensioning wheel 37 is installed on the middle part of the side of the frame 3 near the water reservoir 1 through a spring rod. The tensioning wheel 37 can automatically adjust its position according to the tension of the metal wire, always keep the metal wire in an appropriately tensioned state, ensure the stability of the metal wire in the entire processing process, and avoid affecting the forming quality of the corrugated pipe due to loose metal wire.

[0022] Furthermore, a driving motor 17 is fixedly installed on the rear side of the fixed plate 15 and the driving end of the driving motor 17 is installed on the rear side of the corrugated tube forming mold 16. The driving motor 17 serves as a power source for the rotation of the corrugated tube forming mold 16 and can provide stable and strong power to drive the corrugated tube forming mold 16 to rotate at a set speed, thereby realizing the winding and forming process of the corrugated tube. A lifting cylinder 19 is fixedly installed on the inner bottom of the frame 3 and the driving end of the lifting cylinder 19 is fixedly installed on the bottom end of the lifting platform 18. The lifting cylinder 19 accurately controls the lifting movement of the lifting platform 18, so that the operator can flexibly adjust the height of the lifting platform 18 according to different production needs to meet the production requirements of corrugated tubes of different specifications.

[0023] Furthermore, a servo motor 26 is fixedly installed on one side of the top of the slide 21 away from the corrugated tube forming mold 16. The servo motor 26 can accurately control the rotation speed and angle of the driving sprocket 27 to provide stable and adjustable power for the winding of the corrugated tube. A driving sprocket 27 is fixedly installed on the driving end of the servo motor 26. The driving sprocket 27 rotates under the drive of the servo motor 26, and drives the driven sprocket 28 and the movable shaft 24 to rotate through the chain 29. One end of the movable shaft 24 extends to the outside of the positioning frame 22 and is fixedly installed with a driven sprocket 28. The outer diameters of the driving sprocket 27 and the driven sprocket 28 on the corresponding side are connected by the chain 29. The chain 29 serves as a medium for power transmission, which accurately transmits the rotational motion of the driving sprocket 27 to the driven sprocket 28, thereby driving the movable shaft 24 and the lower pressure roller 25 to rotate, thereby realizing the winding operation of the corrugated tube.

[0024] Furthermore, a flywheel 30 is movably installed in the middle of the top of the lifting platform 18. Under the drive of the horizontal cylinder 32, the flywheel 30 drives the two slides 21 to move synchronously through the connecting rod 31. The middle of the inner end of the slide 21 is movably installed with a connecting rod 31, and the ends of the connecting rod 31 are movably arranged on both sides of the top of the flywheel 30. When one side of the slide 21 moves under the drive of the horizontal cylinder 32, the connecting rod 31 will drive the flywheel 30 to rotate, and then drive the other side of the slide 21 to move synchronously through the connecting rod 31 on the other side. A horizontal cylinder 32 is also fixedly installed on one side of the top of the lifting platform 18. The horizontal cylinder 32 serves as a power source for the horizontal movement of the slide 21, accurately controls the movement direction and distance of the slide 21, thereby changing the spacing between the two lower pressure rollers 25 to meet the forming width requirements of corrugated pipes of different specifications. The driving end of the horizontal cylinder 32 is fixedly installed at one end of the slide 21 on one side to ensure that the horizontal cylinder 32 can effectively drive the slide 21 to move in the horizontal direction.

[0025] Working principle: First, the metal wire wound on the metal wire roller 2 is pulled out, and the metal wire is slowly pulled out from the metal wire roller 2 to start its processing journey in the entire equipment, and passes through the inside of the sheet forming mold 4, the inside of the cooling water tank 6, the first guide wheel group 14, the tension wheel 37, the left second guide wheel group 23 and the left lower pressure roller 25 in turn. In this process, the metal wire maintains a stable transmission path under the guidance and action of various components, and is finally wound on the corrugated tube forming mold 16 to complete the initial positioning of the metal wire. Subsequently, the drive motor 17 is used to drive the corrugated tube forming mold 16 to rotate and start winding. The drive motor 17 is started to provide continuous and stable rotational power to the corrugated tube forming mold 16, so that it starts at a predetermined speed. The screw extruder 5 rotates, and at the same time, the screw extruder 5 squeezes the heated sheet into the sheet forming mold 4. The screw inside the screw extruder 5, driven by the motor, extrude the sheet heated to a suitable temperature at a certain pressure and speed, and accurately feeds it into the sheet forming mold 4, and the sheet and the metal wire are compounded to form a sheet with a metal wire. In the sheet forming mold 4, the high-temperature sheet and the metal wire are fully combined to form a sheet with a metal wire with a certain strength. The condensate conduit 7 introduces condensate to cool the sheet with the metal wire coming out of the sheet forming mold 4. The condensate flows out from the condensate conduit 7 and evenly falls on the sheet with the metal wire, taking away part of its heat and lowering its temperature. The condensate will fall into the water reservoir 1 through the seepage hole 10. Inside, the condensed water after the first cooling is smoothly returned to the water reservoir 1 through the seepage holes 10 on the bottom wall of the cooling water tank 6, so as to realize the recycling of water resources. At this time, the circulating water pump 12 is started, and the circulating water pump 12 starts to work to extract the condensed water in the water reservoir 1, and pump the condensed water into the drip pipe 8 through the return pipe 13. Under the action of the circulating water pump 12, the condensed water is transported to the drip pipe 8 along the return pipe 13, and slowly drips on the surface of the sheet through the drip valve 9 to perform secondary cooling. The drip valve 9 at the bottom of the drip pipe 8 drips the condensed water in the form of slow water drops on the surface of the sheet with the metal wire that has been cooled once, so as to further reduce the temperature of the sheet and ensure its stability in the subsequent processing. The two water retaining cottons 11 can transfer the cooling water The middle section of the groove 6 forms a left and right semi-closed structure, so that the condensed water can gather in the cooling water groove 6 to improve the cooling effect. The water-retaining cotton 11 effectively blocks the outflow of condensed water, so that the condensed water gathers in the cooling water groove 6 to form a relatively stable cooling environment, thereby improving the cooling effect on the sheet with metal wire. The cooled sheet begins to be wound through the bellows forming mold 16. The sheet with metal wire, which has been cooled twice, now has a suitable temperature and flexibility and begins to be wound on the rotating bellows forming mold 16. At this time, the servo motor 26 is started. The two servo motors 26 are started separately to provide power for the active sprocket 27. The two servo motors 26 drive the active sprocket 27 to rotate. Under the drive of the servo motor 26, the active sprocket 27It starts to rotate rapidly and stably, and through the transmission action of the chain 29, it drives the driven sprocket 28 and the movable shaft 24 to rotate. The chain 29 transmits the rotational motion of the driving sprocket 27 to the driven sprocket 28. The driven sprocket 28 drives the movable shaft 24 to rotate together, thereby driving the lower pressure roller 25 to rotate. The rotation of the movable shaft 24 causes the lower pressure roller 25 to rotate accordingly. The two rotating lower pressure rollers 25 cooperate with the rotating corrugated tube forming mold 16 to start the winding process of the corrugated tube. The two rotating lower pressure rollers 25 cooperate with the rotating corrugated tube forming mold 16 to tightly wind the sheet with metal wire on the corrugated tube forming mold 16 layer by layer, gradually forming the shape of the corrugated tube. At the same time, the hot glue gun 35 sprays hot glue to stick the wound sheets together to form a corrugated tube. The hot glue gun 35 sprays high-temperature hot glue in a timely manner during the winding process of the corrugated tube. The hot glue is evenly applied between the wound sheets to make them firmly stick together, and finally form a complete corrugated tube. Compared with the traditional molding machine, the sheet and the metal wire are thermally compounded at the mold to form a corrugated tube. In this scheme, a sheet with a metal wire is first formed, and then thermally compounded to form a corrugated tube. The corrugated tube of this structure has high strength, good support, good quality, and is suitable for heavy-duty pipes. This innovative production method makes the metal wire inside the corrugated tube more tightly combined with the sheet, thereby improving the overall strength and The supporting force enables it to meet the requirements of heavy-duty pipes. In addition, the vertical cylinder 33 drives the upper pressure roller 34 to descend, so that it is attached to the top of the corrugated pipe being wound, thereby improving the stability of the winding process. The vertical cylinder 33 is started, pushing the upper pressure roller 34 to move downward, so that it is gently attached to the top of the corrugated pipe being wound, providing additional pressure for the winding process of the corrugated pipe, ensuring that the material sheet will not loosen or deviate during the winding process, further improving the stability of the winding process. In addition, the slide 21 on one side can be driven inward by the horizontal cylinder 32. The horizontal cylinder 32 is started, and its driving end pushes the slide 21 on one side to move inward along the guide rail 20. When the slide 21 moves, One side of the connecting rod 31 is driven to follow the movement, so that the other side of the connecting rod 31 drives the flywheel 30 to rotate. The movement of the slide 21 is transmitted to the flywheel 30 through the connecting rod 31, so that the flywheel 30 starts to rotate. The rotating flywheel 30 pushes and pulls the connecting rod 31 on the other side at the same time, so that the two slides 21 move inward or outward at the same time, changing the distance between the two lower pressure rollers 25, which is convenient for adjusting the forming width of the corrugated tube. The rotation of the flywheel 30 drives the slide 21 on the other side to move synchronously through the connecting rod 31, thereby realizing the adjustment of the distance between the two lower pressure rollers 25. The operator can flexibly adjust the distance between the lower pressure rollers 25 according to the production requirements of corrugated tubes of different specifications to ensure the production of corrugated tubes that meet the requirements.
