Description

Technical Field

[0001] This utility model relates to the field of pipe forming technology, and more specifically, to a mold for forming antibacterial stainless steel composite pipes. Background Technology

[0002] Antibacterial stainless steel composite pipe is a new type of pipe made of stainless steel and other materials, and specially treated to give it antibacterial properties. This pipe combines the corrosion resistance and high strength of stainless steel with the good processing performance of carbon steel, and at the same time utilizes antibacterial technology to achieve a highly efficient antibacterial effect.

[0003] Antibacterial stainless steel composite pipes have a wide range of applications. Due to their excellent antibacterial properties and corrosion resistance, they are particularly suitable for occasions with high hygiene requirements, such as medical, pharmaceutical, and food processing fields. During the production process, antibacterial stainless steel composite pipes undergo a series of precise processing techniques, such as forging, rolling, and welding, to form the required shape and size. At the same time, in order to impart antibacterial properties, a chemical agent is applied to the inside of the pipe to further achieve shaping and antibacterial properties.

[0004] Currently, when shaping the coating inside pipes, heating is used to quickly shape the coating. This requires pushing multiple sets of steel pipes into the furnace for heating. To ensure the coating adheres to the inner wall of the pipe, air needs to be circulated inside the steel pipe during heating to ensure a tight fit between the coating and the pipe wall. However, in actual use, workers need to fix the steel pipes when they are sent into the furnace, and the high temperature inside the furnace makes the working environment for workers poor. Therefore, a forming mold that facilitates fixing and heating multiple sets of pipes is needed. Utility Model Content

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] like Figures 1 to 7 As shown, this utility model provides an antibacterial stainless steel composite pipe forming mold, including a heating chamber 1, a base 2 fixedly installed at the bottom of the heating chamber 1, a moving cart 3 set at the top of the base 2, and partitions 17 detachably installed at both ends of the top of the moving cart 3, and a pipe 19 welded between the two sets of partitions 17.

[0033] Guide rails 5 are provided at both the front and rear ends of the top of the base 2. The bottom of the mobile vehicle 3 is rotatably equipped with tires 4, which are located inside the guide rails 5. A brake block 7 is fixedly installed at the leftmost end of the guide rails 5. A movable groove 11 is provided inside the guide rails 5. A movable plate 10 is movably installed inside the movable groove 11. Telescopic blocks 8 are fixedly installed at the four corners of the movable plate 10. All four sets of telescopic blocks 8 are located inside the guide rails 5. The bottom of the telescopic blocks 8 and the inner wall of the movable groove 11 are elastically connected by a first spring 9. Control plates 12 are fixedly installed at the left and right ends of the movable plate 10. The control plates 12 are located on the right side of the base 2.

[0034] When the coating inside the pipe needs to be heat-formed, the workers first install the partition plate 17 and the support plate 18. First, based on the length of the pipe 19, the workers install the partition plate 17 on the left and right sides of the moving vehicle 3, and then install the support plate 18 between the two sets of partition plates 17. At this point, the workers only need to align the bottom of the partition plate 17 with the mounting groove 22 and press the partition plate 17 downwards. Further, the outer wall of the partition plate 17 will squeeze the wedge 27 into the control groove 26. After the partition plate 17 is completely inside the mounting groove 22, the wedge 27 is reset by the elastic potential energy of the fourth spring 28, completing the installation of the partition plate 17. At this time, the pad 24 will be activated by the third spring 25. The elastic potential energy always provides an upward force to the partition 17, further ensuring a tight fit between the fixing groove 23 and the wedge 27, increasing friction, and preventing the wedge 27 from loosening due to vibration. After the partition 17 and support plate 18 are installed, the worker inserts the pipe 19 with a coating on its inner wall through the partition 17 and support plate 18, and then welds both ends of the pipe 19 to the partition 17. Finally, the worker rotates the sealing cap 20 to cover the outer wall of the partition 17. At this time, the worker can introduce gas into the sealing cap 20 through the pressure regulating valve 21 to make the air pressure on the inner wall of the pipe 19 between 0.8-1.2 MPa. Then, the worker moves the mobile vehicle 3 over the ramp. 6. Push the trolley 3 onto the guide rail 5 and push it into the heating chamber 1. At this time, due to the inclined design of the telescopic block 8, the tire 4 will press the telescopic block 8 downward when the trolley 3 is pushed, compressing the first spring 9. When the tire 4 at the bottom of the trolley 3 abuts against the brake block 7, it means that the trolley 3 has completely entered the heating chamber 1. At this time, the telescopic block 8 will reset through the elastic potential energy of the first spring 9, fixing the tire 4 with the brake block 7 and the telescopic block 8 to prevent the trolley 3 from shaking. After the operator closes the heating chamber 1, the pipe 19 is heated by the electric heating wire inside the heating chamber 1 to perform high-temperature and high-pressure shaping of the coating on the inner wall of the pipe 19. After completion... The worker opens the heating chamber 1 to cool it down and steps on the control plate 12. The control plate 12 moves downward along the movable groove 11. As the control plate 12 moves downward, its bottom presses against the round top of the fixing head 15, causing the fixing head 15 to be retracted into the fixing block 14. When the fixing head 15 is aligned with the fixing hole 13, the fixing head 15 will be reset by the elastic potential energy of the second spring 16 and enter the fixing hole 13, fixing the control plate 12. At this time, the worker can move the moving cart 3 out of the base 2, remove and replace the partition plate 17 and the support plate 18, and remove the 5 cm long section of the pipe 19 welded to the partition plate 17, keeping the middle part, to complete the molding operation.

[0035] With the guide rail 5 and ramp 6 in place, the operator can easily push the mobile cart 3 into the heating chamber 1. When the mobile cart 3 is fully pushed into the heating chamber 1, the telescopic block 8 will reset due to the elastic potential energy of the first spring 9, which will fix the tire 4 with the brake block 7 and the telescopic block 8. Finally, the operator can step on the control plate 12 to retract the telescopic block 8 into the movable slot 11, and then move the mobile cart 3 out. Compared with traditional devices, this device can easily and conveniently push the mobile cart 3 into the heating chamber 1 to form the pipe 19, while ensuring the stability of the pipe 19 during high temperature and high pressure forming operations, reducing the workload and improving work efficiency.

[0036] The top of the mobile vehicle 3 is provided with a mounting slot 22, which is arranged horizontally on the top of the mobile vehicle 3.

[0037] The partition 17 can be detachably installed inside the mounting slots 22 on both the left and right sides. The bottom outer wall of the partition 17 has a fixing slot 23. The inner wall of the mounting slot 22 has a control slot 26. The wedge 27 is movably installed inside the control slot 26. The wedge 27 and the control slot 26 are elastically connected by a fourth spring 28.

[0038] The operator only needs to align the bottom of the partition 17 with the mounting groove 22 and press the partition 17 down. The outer wall of the partition 17 will further squeeze the wedge 27 into the control groove 26. After the partition 17 is fully inserted into the mounting groove 22, the wedge 27 will be reset by the elastic potential energy of the fourth spring 28, thus completing the installation of the partition 17.

[0039] By aligning the partition 17 and support plate 18 with the mounting groove 22 and pressing them together, the partition 17 and support plate 18 are fixed inside the mounting groove 22. When disassembly is required, the worker can push the pull plate 29 to remove the partition 17, which will then pop out automatically. Compared with traditional devices, this device, with its multiple mounting grooves 22, allows the worker to install the partition 17 using the length of the pipe 19. The installation of the partition 17 and support plate 18 is quick and efficient, effectively improving work efficiency and reducing workload. At the same time, the pad 24 and the third spring 25 ensure the stability of the wedge 27 and prevent the partition 17 from shaking and falling off.

[0040] Each of the two sets of partitions 17 has a sealing cap 20 threaded onto one end, and a pressure stabilizing valve 21 is fixedly installed on the outer wall of the sealing cap 20.

[0041] The operator rotates the sealing cap 20 and places it on the outer wall of the partition 17 to achieve a seal. At this time, the operator can introduce gas into the sealing cap 20 through the pressure regulating valve 21 to make the air pressure on the inner wall of the pipe 19 between 0.8-1.2 MPa, thus ensuring high pressure inside the pipe 19.

[0042] Among them, the leftmost end of the two sets of guide rails 5 is provided with a ramp 6, and the control plate 12 is located between the two sets of ramps 6.

[0043] The operator can temporarily fix the control plate 12 by stepping down on it. If the telescopic block 8 needs to be restored, the operator can lift the control plate 12 up with his foot. At this time, due to the dome-shaped design of the fixing head 15, the fixing head 15 will be stored inside the fixing block 14 and will not hinder the upward movement of the control plate 12.

[0044] Two sets of fixing blocks 14 are fixedly installed on the right end of the base 2. Fixing heads 15 are movably installed inside the two sets of fixing blocks 14. The fixing heads 15 and the inner wall of the fixing blocks 14 are elastically connected by a second spring 16.

[0045] The control board 12 has fixing holes 13 corresponding to the fixing heads 15 at both the front and rear ends, and the opposite ends of the two sets of fixing heads 15 are dome-shaped.

[0046] When the control plate 12 moves downward, the bottom of the control plate 12 will press the round top of the fixing head 15, so that the fixing head 15 is housed inside the fixing block 14. When the fixing head 15 is aligned with the fixing hole 13, the fixing head 15 will be reset into the fixing hole 13 by the elastic potential energy of the second spring 16, thus fixing the control plate 12.

[0047] The mounting groove 22 has a pad 24 movably mounted inside it, and the pad 24 and the inner wall of the mounting groove 22 are elastically connected by a third spring 25.

[0048] The pad 24 will always give the partition 17 an upward force through the elastic potential energy of the third spring 25, further ensuring the tight fit between the fixing groove 23 and the wedge 27, increasing the friction and preventing the wedge 27 from loosening due to vibration.

[0049] Among them, a pull plate 29 is fixedly installed on the top of the wedge 27, and the pull plate 29 extends through to the top of the moving vehicle 3.

[0050] The mounting groove 22 has a detachable support plate 18 installed inside, and the support plate 18 and the pipe 19 are movably connected.

[0051] When the pipe 19 is long, workers can install support plates 18 to support the pipe 19 and prevent it from bending.

[0052] The inclined surface of the wedge 27 is opened upward, and one end of the wedge 27 abuts against the fixing groove 23.

[0053] Working principle and usage process of this utility model:

[0054] When the coating inside the pipe needs to be heat-formed, the workers first install the partition plate 17 and the support plate 18. First, based on the length of the pipe 19, the workers install the partition plate 17 on the left and right sides of the moving vehicle 3, and then install the support plate 18 between the two sets of partition plates 17. At this point, the workers only need to align the bottom of the partition plate 17 with the mounting groove 22 and press the partition plate 17 downwards. Further, the outer wall of the partition plate 17 will squeeze the wedge 27 into the control groove 26. After the partition plate 17 is completely inside the mounting groove 22, the wedge 27 is reset by the elastic potential energy of the fourth spring 28, completing the installation of the partition plate 17. At this time, the pad 24 will be activated by the third spring 25. The elastic potential energy always provides an upward force to the partition 17, further ensuring a tight fit between the fixing groove 23 and the wedge 27, increasing friction, and preventing the wedge 27 from loosening due to vibration. After the partition 17 and support plate 18 are installed, the worker passes the pipe 19 with a coating on its inner wall through the partition 17 and support plate 18, and then welds both ends of the pipe 19 to the partition 17. Finally, the worker rotates the sealing cap 20 to cover the outer wall of the partition 17. At this time, the worker can introduce gas into the sealing cap 20 through the pressure regulating valve 21 to make the air pressure on the inner wall of the pipe 19 between 0.8-1.2 MPa. Then the worker moves the moving vehicle 3 across the ramp 6. Push the trolley 3 onto the guide rail 5 and push it into the heating chamber 1. Due to the inclined design of the telescopic block 8, the tire 4 will press the telescopic block 8 downwards as the trolley 3 is pushed, compressing the first spring 9. When the tire 4 at the bottom of the trolley 3 abuts against the brake block 7, it indicates that the trolley 3 has completely entered the heating chamber 1. At this point, the telescopic block 8 will reset through the elastic potential energy of the first spring 9, fixing the tire 4 in place with the brake block 7 and the telescopic block 8, preventing the trolley 3 from shaking. After the operator closes the heating chamber 1, the pipe 19 is heated by the electric heating wire inside the heating chamber 1 to perform high-temperature and high-pressure shaping of the coating on the inner wall of the pipe 19. After completion, the work... The operator opens the heating chamber 1 for cooling and steps on the control plate 12. The control plate 12 moves downward along the movable groove 11. As the control plate 12 moves downward, its bottom presses against the round top of the fixing head 15, causing the fixing head 15 to be retracted into the fixing block 14. When the fixing head 15 is aligned with the fixing hole 13, the fixing head 15 is reset by the elastic potential energy of the second spring 16 and enters the fixing hole 13, fixing the control plate 12. At this time, the operator can move the moving cart 3 out of the base 2, remove and replace the partition plate 17 and the support plate 18, and cut the part (5 cm long) where the pipe 19 is welded to the partition plate 17, keeping the middle part, to complete the molding operation.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
