Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe stretching technology, specifically to a water-cooled lifting mold box device. Background Technology

[0002] Stainless steel pipe drawing equipment is a key piece of equipment used for the cold forming of stainless steel pipes. It mainly uses a coil drawing method to draw metal pipes. The drawing process of the coil drawing machine is continuous, with high linear speed and high productivity. It can provide products in coil form to the winding and packaging process. The drawing principle of the coil drawing machine is: the metal pipe is tightly wound on the outer surface of the coil in a spiral manner. The rotation of the coil pulls the pipe continuously through the drawing die, so that the pipe diameter and wall thickness meet the product requirements. It is widely used in chemical, medical device, food machinery and other fields to provide high-quality blanks or finished products for high-pressure pipelines and precision pipe fittings.

[0003] Chinese Utility Model Patent Publication No. CN220277889U discloses a disc drawing machine. The specification of this machine states that "a support block is fixedly connected to the top surface of the pad away from the drawing die; a second through hole coaxial with the first through hole is provided on the support block; a pair of straightening wheels are rotatably connected to the top surface of the pad; each pair of straightening wheels has an annular groove on its outer circumference; the pair of annular grooves cooperate to form a channel gap through which the pipe can pass; the channel gap is coaxial with the first through hole. By adopting the above technical solution, during the process of the disc rotating and pulling the pipe continuously through the drawing die, the pipe extends out from the second through hole towards the drawing die..." Before entering the drawing die, the pipe moving inside the die passes through a channel gap formed by a pair of straightening wheels. The movement of the pipe is guided and limited by the annular grooves on the outer circumference of the straightening wheels, reducing the possibility of the pipe deviating when entering the drawing die and ensuring that the pipe is subjected to uniform force in the drawing die. However, the straightening wheels cannot be adjusted, and their positions are fixed. In actual use, they cannot be adjusted according to the diameter of the pipe. At the same time, this drawing machine is only equipped with a single set of drawing dies, and the drawing dies have not been improved. It cannot improve the drawing efficiency, nor can it cool and lubricate the drawing dies, thus failing to extend the service life of the drawing die assembly. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a water-cooled lifting mold box device to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled lifting mold box device, including a coiling machine frame, a drive unit, a coil cylinder, and a protection unit. A lifting assembly is provided on the outer side of the coiling machine frame, and a top plate is installed on the outer side of the coiling machine frame via the lifting assembly.

The slider is fixedly connected to the top plate, and the guide rail is fixedly connected to the back plate.

[0007] Preferably, there are two identical guide rails and sliders, which are located between the top plate and the back plate, and the center lines of the cylinder and the top plate are on the same vertical line.

[0008] Through the above technical solution, during the stretching process of stainless steel tube, the cylinder can push the top plate through the connecting seat and move upward under the guidance of the guide rail and slider. At this time, the top plate can drive the straightening and correction components to move upward, ensuring that the stainless steel tube can be stably wound on the outside of the disc under the protection of the protection unit.

[0009] Preferably, the straightening and correcting assembly includes a straightening seat, which is fixedly installed on one side of the top of the top plate. The top of the straightening seat is provided with several identical plug-in blocks. The connection between the plug-in blocks and the straightening seat is provided with an installation groove adapted to the straightening seat. A rotating rod is rotatably installed on the top of the plug-in block. A straightening and correcting wheel is provided on the outer side of the rotating rod. A snap-fit ​​groove is provided on the outer side of the plug-in block. A snap-fit ​​block is snapped into the inside of the snap-fit ​​groove. A threaded rod is rotatably installed on the end of the snap-fit ​​block away from the plug-in block. A handwheel is fixedly connected to the outer side of the threaded rod. An upper fixing plate is provided on the upper part of the connection between the plug-in block and the straightening seat.

[0010] Preferably, the threaded rod and the correction seat are threadedly connected, the center lines of the snap-fit ​​block, the threaded rod and the handwheel are on the same horizontal line, the number of upper fixing plates is twice that of the plug-in blocks, the upper fixing plates are located at the connection between the plug-in blocks and the correction seat, and the upper fixing plates and the correction seat are in an abutting connection.

[0011] With the above technical solution, the threaded rod is rotated by turning the handwheel, and the threaded rod is threadedly connected to the correction seat. At this time, the threaded rod can push the snap block to move towards the insertion block. The insertion block can drive the correction and straightening wheel to move through the rotating rod to achieve the best correction and straightening effect.

[0012] Preferably, the drawing die assembly includes a drawing die box, inside which are arranged a first drawing die and a second drawing die. A lubrication cavity is formed between the first drawing die and the drawing die box, and a lubrication cavity is formed between the second drawing die and the first drawing die. An oil outlet and an oil filling port are respectively opened on both sides of the drawing die box. An inlet pipe hole is opened on the side of the drawing die box near the straightening and correction assembly. Cooling channels are arranged inside the first drawing die and the second drawing die. An inlet and an outlet are respectively provided at both ends of the cooling channels. A cover plate is provided at the top of the drawing die box.

[0013] Preferably, the first drawing die is located in front of the second drawing die, the horizontal center lines of the first drawing die and the second drawing die are on the same straight line, the lubrication chambers one and two are filled with lubricating oil, the drawing die hole diameter of the second drawing die is larger than the drawing die hole diameter of the first drawing die, the distance between the oil outlet and the top plate is greater than the distance between the oil filling port and the top plate, and the diameter of the inlet pipe hole is in tight contact with the outer diameter of the stainless steel pipe.

[0014] Through the above technical solution, a drawing die assembly with lubrication and cooling functions is formed, effectively meeting the requirements of the stainless steel tube drawing process. Simultaneously, the horizontal center lines of drawing die one and drawing die two are located on the same straight line, effectively preventing the stainless steel tube from shifting during the drawing process and avoiding differences in the outer wall thickness of the stainless steel tube. Furthermore, the different drawing die orifice diameters of drawing die one and drawing die two allow for gradual drawing of the stainless steel tube, improving the accuracy and quality of the drawing process. The cooling flow channel, as well as the liquid inlet and outlet, are designed to communicate with an external circulating water unit, enabling water cooling of the drawing die and preventing the die from overheating due to prolonged drawing, which could affect the die's lifespan and drawing quality. The oil outlet and oil filler allow for the circulation and replenishment of lubricating oil within the lubrication chamber, providing excellent lubrication conditions for the drawing process, reducing friction between the stainless steel tube and drawing die one and drawing die two, reducing wear, and improving the drawing quality.

[0015] Compared with the prior art, the present invention provides a water-cooled lifting mold box device, which has the following beneficial effects: 1. This water-cooled lifting mold box device uses a cylinder to push the top plate through a connecting seat. The cooperation between the guide rail and the slider achieves precise guidance, ensuring that the top plate drives the straightening and correction components and the pulling mold components to rise and fall stably. This allows the stainless steel tube to be accurately wound on the outside of the disc under the action of the protection unit during the stretching and winding process. At the same time, the straightening and correction components can adjust the position of the straightening and correction wheel through the handwheel, threaded rod and snap-fit ​​block, effectively ensuring the straightness and positional accuracy of the stainless steel tube feeding. 2. This water-cooled lifting mold box device, through the design of the first and second pulling molds, ensures that the center lines of the first and second pulling molds are collinear, avoiding the offset of the stainless steel tube during pulling and ensuring the uniform thickness of the outer wall of the tube. The different hole diameter design improves the pulling efficiency. The cooling channel, combined with the liquid inlet and liquid outlet, achieves water cooling and prevents the mold from being damaged by high temperature. The oil outlet and oil filling port ensure the circulation and replenishment of lubricating oil, reducing the friction between the stainless steel tube and the mold, and improving the pulling quality and the service life of the mold.

[0024] Example 4: like Figure 2-10 As shown, as an improvement to the previous embodiment, this is done to ensure stable die-drawing operation.

[0025] Specifically, the die-drawing assembly 11 includes a die-drawing box 1101. Inside the die-drawing box 1101 are die-drawing mold one 1102 and die-drawing mold two 1103. A lubrication cavity one 1104 is formed between die-drawing mold one 1102 and the die-drawing box 1101, and a lubrication cavity two 1109 is formed between die-drawing mold two 1103 and die-drawing mold one 1102. An oil outlet 1105 and an oil filling port 1106 are respectively opened on both sides of the die-drawing box 1101.

The diameter of inlet hole 1107 is in tight contact with the outer diameter of stainless steel pipe 13. The advantages are that a drawing die assembly 11 with lubrication and cooling functions is formed, effectively meeting the drawing process of stainless steel tube 13. Simultaneously, the horizontal center lines of drawing die one 1102 and drawing die two 1103 are on the same straight line, effectively preventing the stainless steel tube 13 from shifting during the drawing process and avoiding differences in the outer wall thickness of the stainless steel tube 13. Furthermore, the different drawing die orifice diameters of drawing die one 1102 and drawing die two 1103 allow for gradual drawing of the stainless steel tube 13, improving the accuracy and quality of the drawing process. The cooling flow channel 1110... The inlet 1111 and outlet 1112 are designed to communicate with an external circulating water unit, which can cool the drawing die with water to prevent the die from being affected by high temperature due to long-term drawing and thus affecting the die life and drawing quality. The oil outlet 1105 and oil filling port 1106 can realize the circulation and replenishment of lubricating oil in the lubrication cavity, providing good lubrication conditions for the drawing process, reducing the friction between the stainless steel pipe 13 and the first drawing die 1102 and the second drawing die 1103, reducing wear and improving the drawing quality.

[0026] Working principle: During use, the stretched stainless steel tube 13 passes through the straightening and correction assembly 10 and the drawing die assembly 11 into the outer side of the drum 6. The jaw assembly 12 on the outer side of the drum 6 engages with the stainless steel tube 13. After engagement is complete, the drive unit 2 drives the drum 6 to rotate, causing the stainless steel tube 13 to wind around the outer side of the drum 6. During the winding process, the lifting assembly 8 pushes the straightening and correction assembly 10 and the drawing die assembly 11 slowly upward through the top plate 9, positioning the stainless steel tube 13 on the outer side of the drum 6. Above the outer notch, and continuously rising to the normal winding position, when adjusting the straightening and correcting assembly 10, use the handwheel 1009 to turn the threaded rod 1008. The threaded rod 1008 is threadedly connected to the straightening seat 1001. At this time, the threaded rod 1008 can push the locking block 1007 towards the insertion block 1003. The insertion block 1003 can drive the straightening and correcting wheel 1005 to move through the rotating rod 1004 to achieve the best straightening and correcting effect. In order to achieve stable mold pulling operation... The horizontal center lines of the first drawing die 1102 and the second drawing die 1103 are located on the same straight line, which can effectively prevent the stainless steel tube 13 from shifting during the drawing process and avoid differences in the outer wall thickness of the stainless steel tube 13. At the same time, the different drawing die hole diameters of the first drawing die 1102 and the second drawing die 1103 can realize the step-by-step drawing of the stainless steel tube 13, improving the accuracy and quality of the drawing process. The cooling channel 1110 and the liquid inlet 1111 and liquid outlet 1112 are also designed. The liquid inlet 1111 and liquid outlet 1112 can communicate with the external circulating water unit, which can cool the drawing die with water to prevent the die from being affected by high temperature due to long-term drawing and thus affecting the die life and drawing quality. The lubricating oil can be circulated and replenished in the lubrication cavity through the oil outlet 1105 and the oil filling port 1106, providing good lubrication conditions for the drawing process, reducing the friction between the stainless steel pipe 13 and the first drawing die 1102 and the second drawing die 1103, reducing wear and improving the drawing quality.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
