Description

Technical Field

[0001] This utility model relates to the field of spring tube processing technology, and more specifically to an automatic spring tube forming equipment. Background Technology

[0002] Metal Bourdon tubes are elastic pipes made of metal materials through spiral winding or forming processes. They possess excellent flexibility, shock absorption, and media transmission capabilities. Their core characteristics include the ability to withstand large deformations and displacements, good corrosion resistance, and adaptability to various applications, making them widely used in industrial, sanitary ware, and automotive fields.

[0003] Currently, when processing spring tubes, a method is used to wind the spiral tube around the surface of the forming mold. When the forming is complete, the spring tube will be wrapped around the surface of the mold. At this point, the spring tube needs to be rotated in the opposite direction to remove it from the surface of the mold. However, this process delays the spring tube forming process, resulting in a decrease in the efficiency of spring tube forming.

[0004] In view of this, the present invention proposes an automatic spring tube forming device to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic spring tube forming device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an automatic spring tube forming device, including a frame, a pressure wheel is provided on the upper right side of the frame, a central shaft is rotatably connected to the right side of the frame, a drive motor for driving the central shaft to rotate is fixedly installed on the left side of the frame, a smooth rod is fixedly installed at the right end of the central shaft, the side cross section of the smooth rod is rectangular, and a forming mold for forming the tube is provided on the surface of the smooth rod.

[0007] The forming mold includes a rectangular sleeve, which is slidably mounted on the surface of the light rod. A shaping cylinder is fixedly mounted on the surface of the rectangular sleeve. A spiral groove is opened on the surface of the shaping cylinder. The spiral groove corresponds to the position of the pressure wheel.

[0008] Furthermore, a control panel is fixedly mounted on the surface of the frame, and the control panel is electrically connected to an external power source via wires.

[0009] As a further description of the above technical solution: By setting up a control panel, it is convenient to intelligently control the entire device.

[0010] Furthermore, the clamping wheel is movably mounted on the surface of the frame, a crossbeam is fixedly mounted on the right side of the frame, a hydraulic rod is embedded in the surface of the crossbeam, the hydraulic rod is connected to the external hydraulic station pipeline, a lifting seat is fixedly mounted on the telescopic end of the hydraulic rod, the clamping wheel is rotatably mounted on the surface of the lifting seat, and an arc-shaped annular groove is opened on the outer arc surface of the clamping wheel corresponding to the pipe fitting.

[0011] As a further description of the above technical solution: by controlling the extension and retraction of the hydraulic rod, the height of the lifting platform can be adjusted according to the work progress.

[0012] Furthermore, a limiting slide rod is fixedly installed on the top of the lifting seat, and the limiting slide rod is slidably connected to the cross frame.

[0013] As a further description of the above technical solution: by setting a limit slide bar, the movement path of the lifting seat can be limited, ensuring the stability of the lifting seat and the pressure roller.

[0014] Furthermore, the clamping assembly includes a positioning sleeve fixedly installed on the back of the rectangular sleeve. The positioning sleeve has a rectangular cross-section. A rectangular slide is inserted into the back of the positioning sleeve. A clamping plate for clamping the end of the pipe is fixedly installed on the left end of the rectangular slide. An adjusting screw is threadedly connected to the surface of the rectangular slide, and one end of the adjusting screw extending into the inside of the positioning sleeve is rotatably connected to the positioning sleeve.

[0015] As a further description of the above technical solution: by setting up a clamping component, stable clamping of the pipe end can be achieved, thereby ensuring the stability of the pipe during the forming process, preventing the pipe from shifting or falling off during processing, and improving processing accuracy and safety.

[0016] Furthermore, the surface of the lifting seat is embedded with an oil pipe, the inside of which contains lubricating oil. The oil outlet at the bottom of the oil pipe faces the pressure wheel, and a stepped groove is formed on the inner wall of the oil outlet. A plug is slidably connected to the inner wall of the stepped groove, and a support spring is provided on the inner wall of the stepped groove to drive the plug to seal the oil outlet. A protrusion is fixedly installed on the outer ring surface of the pressure wheel.

The position of the forming mold is adjusted, and the hydraulic rod extends to drive the clamping wheel to press the tube. At this time, the drive motor drives the central shaft and the guide rod to rotate. Under the clamping effect of the clamping wheel, the tube can wind into the spiral groove, achieving the purpose of spring tube forming. After processing, the hydraulic rod is controlled to retract, causing the clamping wheel to move upwards and away. The forming mold can then be directly removed from the guide rod surface, and another forming mold can be directly used for replacement. Furthermore, during the forming process, the spring tube and the forming mold are separated externally. This processing method greatly improves the efficiency of spring tube forming.

The automatic spring tube forming equipment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1 to 5 This utility model provides an automatic spring tube forming equipment, including a frame 1. A control panel 8 is fixedly installed on the surface of the frame 1. The control panel 8 is electrically connected to an external power source through wires. By setting the control panel 8, it is convenient to intelligently control the entire equipment.

[0029] A pressure roller 2 is provided on the upper right side of the frame 1.

[0030] The clamping wheel 2 is movably mounted on the surface of the frame 1. A crossbeam 9 is fixedly mounted on the right side of the frame 1. A hydraulic rod 10 is embedded in the surface of the crossbeam 9. The hydraulic rod 10 is connected to the external hydraulic station pipeline. A lifting seat 11 is fixedly mounted on the telescopic end of the hydraulic rod 10. The clamping wheel 2 is rotatably mounted on the surface of the lifting seat 11. An arc-shaped groove is opened on the outer arc surface of the clamping wheel 2 corresponding to the pipe fitting 7.

[0031] A central shaft 3 is rotatably connected to the right side of the frame 1, and a drive motor 4 for driving the central shaft 3 to rotate is fixedly installed on the left side of the frame 1. A guide rod 5 is fixedly installed at the right end of the central shaft 3. The side cross section of the guide rod 5 is rectangular, and a forming mold 6 for forming the pipe 7 is provided on the surface of the guide rod 5.

[0032] The forming mold 6 includes a rectangular sleeve 601, which is slidably mounted on the surface of the light rod 5. A shaping cylinder 602 is fixedly mounted on the surface of the rectangular sleeve 601. A spiral groove 603 is opened on the surface of the shaping cylinder 602. The spiral groove 603 corresponds to the position of the pressure wheel 2. A clamping component 604 for positioning the end of the pipe 7 is provided on the right side opening of the rectangular sleeve 601 corresponding to the spiral groove 603.

[0033] The clamping assembly 604 includes a positioning sleeve 6041 fixedly installed on the back of a rectangular sleeve 601. The positioning sleeve 6041 has a rectangular cross-section. A rectangular slide 6042 is inserted into the back of the positioning sleeve 6041. A clamping plate 6043 for clamping the end of the pipe fitting 7 is fixedly installed on the left end of the rectangular slide 6042. An adjusting screw 6044 is threadedly connected to the surface of the rectangular slide 6042, and one end of the adjusting screw 6044 extends into the interior of the positioning sleeve 6041 and is rotatably connected to the positioning sleeve 6041.

[0034] By rotating the adjusting screw 6044, the rectangular slide 6042 and the clamping plate 6043 can be pushed to clamp the pipe 7, ensuring the stability of the pipe 7 during the forming process, preventing the pipe 7 from shifting or falling off during the processing, and improving the processing accuracy and safety.

[0035] When using this automatic spring tube forming equipment, the tube 7 is positioned at the right end opening of the spiral groove 603 using the clamping assembly 604. The position of the overall forming mold 6 is adjusted so that the hydraulic rod 10 extends to drive the clamping roller 2 to clamp the tube 7. At this time, the drive motor 4 drives the central shaft 3 and the guide rod 5 to rotate. Under the clamping effect of the clamping roller 2, the tube 7 can be wound into the spiral groove 603 to achieve the purpose of spring tube forming. After the processing is completed, the hydraulic rod 10 is controlled to retract, causing the clamping roller 2 to move upward and away. At this time, the forming mold 6 can be directly removed from the surface of the guide rod 5 to the right, and then another forming mold 6 can be directly used for replacement. During the synchronous forming process, the spring tube and the forming mold 6 are separated from the outside of the equipment. This processing method greatly improves the efficiency of spring tube forming.

A protrusion 17 is fixedly installed on the outer ring surface of the pressure wheel 2. When the pressure wheel 2 rotates, the protrusion 17 pushes the plug 14 and the support spring 16 upward to make the oil outlet open.

[0039] It is worth noting that by setting up the oil pipe 13, the plug 14 and the support spring 16, the plug 14 and the support spring 16 can be pushed by the protrusion 17 during the rotation of the pressure wheel 2, so that the lubricating oil inside the oil pipe 13 can be discharged intermittently to lubricate the outer ring surface of the pressure wheel 2, reduce the friction between the pressure wheel 2 and the pipe 7, ensure that the pipe 7 can be smoothly wound into the spiral groove 603, and extend the service life of the pressure wheel 2.
