Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, specifically a stretching device for copper tube processing. Background Technology

[0002] A stretching device for copper tube processing is a piece of equipment used to stretch copper tubes, aiming to improve production efficiency and product quality. This device typically includes several components, such as a stretching assembly, a feeding mechanism, positioning dies, and stretching dies, to ensure the stability and precision of the copper tubes during processing.

[0003] Conventional stretching devices apply force in one direction when stretching copper tubes, which can lead to uneven force on the stretched part and cause deformation deviations. This results in limited quality of the stretching process. In addition, the copper tube itself has a large span during the stretching process and lacks good structural stability, making it susceptible to influence during the stretching process.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a stretching device for copper tube processing. Utility Model Content

[0005] The purpose of this invention is to provide a stretching device for copper tube processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stretching device for copper tube processing, comprising a device frame and a guide straightening frame. Support rails are symmetrically installed on the left and right sides of the middle of the device frame, and stretching frame assemblies are symmetrically connected to both ends of the support rails. A copper tube body is horizontally arranged in the middle of the stretching frame assembly. The guide straightening frame is symmetrically installed on both ends of the device frame. The guide straightening frame includes a fixed plate, a guide tube, a stabilizing frame, an adjusting screw, and a straightening wheel. A guide tube is installed in the middle of the fixed plate, and a stabilizing frame is symmetrically installed on one side of the fixed plate. Adjusting screws are horizontally inserted through both ends of the stabilizing frame, and a fixed frame is installed at one end of the adjusting screw. A straightening wheel is installed on the side of the fixed frame away from the adjusting screw.

[0007] Furthermore, the support rail is horizontally installed on the inner side of the middle part of the device frame, and the guide straightening frame is fixedly connected to the device frame.

[0008] Furthermore, the tensioning frame assembly includes a support frame, a drive motor, and a lead screw. The drive motor is installed in the upper middle part of the support frame, and the lead screw is vertically installed at the bottom power output end of the drive motor via a coupling.

[0009] Furthermore, the drive motor is vertically mounted at the upper middle of the support frame, and the bottom ends of the left and right sides of the support frame are slidably connected to the support guide rail.

[0010] Furthermore, the tensioning frame assembly also includes a movable mold and a fixed mold, with the movable mold installed at the bottom end of the lead screw and the fixed mold installed directly below the movable mold.

[0011] Furthermore, the fixed mold is fixedly connected to the support frame, and the left and right ends of the movable mold are slidably connected to the support frame.

[0012] Furthermore, a servo motor is installed on one side of the bottom of the device frame, and a bidirectional lead screw is horizontally installed on the power output end of the servo motor through a coupling. The bottom center of the fixed mold is threadedly connected to the bidirectional lead screw, and the movable mold is threadedly connected to the lead screw.

[0013] Furthermore, the fixing plate and the guide tube are integrally formed, the adjusting screw is threadedly connected to the stabilizing frame, and the straightening wheels are equidistantly arranged and installed on one side surface of the fixing frame.

[0014] This utility model provides a stretching device for copper tube processing, which has the following advantages:

[0015] 1. This utility model features symmetrically installed guide straightening frames on both sides of the device frame. By axially rotating the adjusting screw in the middle of the stabilizing frame, the fixed frame connected to the adjusting screw, along with the straightening wheel installed on one side, can be horizontally moved. This allows the symmetrically arranged fixed frames and straightening wheels on both sides of the fixed plate to form a good clamping effect on the sides of the copper tube body. Simultaneously, the staggered straightening wheels effectively straighten the copper tube body. Using this structure, the copper tube body can be straightened both before and after stretching, ensuring the quality of the processed copper tube body. Furthermore, it ensures that both ends of the copper tube body are limited to a certain extent during processing, maintaining sufficient structural stability during stretching and preventing "jumping" at both ends. The guide tube installed in the middle of the fixed plate also assists in guiding and limiting the copper tube body that passes through it.

[0016] 2. This utility model, by installing a tensioning frame assembly in the middle of the device frame, and symmetrically installing support guide rails on the left and right sides of the inner side of the middle of the device frame, works in conjunction with a servo motor and a bidirectional lead screw installed at the bottom of the device frame. When the drive motor drives the lead screw connected to its bottom end to rotate, the movable mold connected to the bottom of the lead screw is pushed towards the fixed mold directly below. After the fixed mold and the movable mold fix the left and right ends of the copper tube body, as the servo motor drives the bidirectional lead screw to rotate horizontally, the tensioning frame assembly holding the copper tube body moves simultaneously along the surfaces of the support guide rails and the bidirectional lead screw to both ends, thereby stretching the copper tube body. Using the above structure, on the one hand, it can provide stable and relatively smooth and uniform stretching at both ends of the copper tube body, ensuring that the force can be applied relatively evenly to the surface of the copper tube body being processed, thereby deforming it and ensuring processing quality. At the same time, the symmetrically arranged tensioning frame assembly can also ensure that the copper tube body is in a stable state during the stretching process to the greatest extent, preventing unnecessary loosening problems.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, a stretching device for copper tube processing includes a device frame 1 and a guide straightening frame 5. Support rails 2 are symmetrically installed on the left and right sides of the middle of the device frame 1, and stretching frame assemblies 3 are symmetrically connected to both ends of the support rails 2. A copper tube body 4 is horizontally arranged in the middle of the stretching frame assemblies 3. The guide straightening frame 5 is symmetrically installed on both ends of the device frame 1. The guide straightening frame 5 includes a fixed plate 501, a guide tube 502, a stabilizing frame 503, an adjusting screw 504, a fixing frame 505, and a straightening wheel 506. The guide tube 502 is installed in the middle of the fixed plate 501, and the stabilizing frame 503 is symmetrically installed on one side of the fixed plate 501. Adjusting screws 504 are horizontally inserted through both ends of the stabilizing frame 503, and a fixing frame 505 is installed at one end of the adjusting screw 504. A straightening wheel 506 is installed on the side of the fixing frame 505 away from the adjusting screw 504. The fixing plate 501 and the guide tube 502 are integrated. The adjusting screw 504 is threadedly connected to the stabilizer 503. The straightening wheels 506 are equidistantly arranged on one side surface of the fixing frame 505. By axially turning the adjusting screw 504 in the middle of the stabilizer 503, the fixing frame 505 connected to the adjusting screw 504 and the straightening wheel 506 installed on one side can be translated in the horizontal direction. This allows the fixing frames 505 and straightening wheels 506 symmetrically arranged on both sides of the fixing plate 501 to form a good clamping effect on the side of the copper tube body 4. At the same time, the straightening wheels 506 arranged alternately on the left and right can effectively straighten the copper tube body 4.

[0024] like Figures 1 to 4As shown, the support rail 2 is horizontally installed on the inner side of the middle of the device frame 1, and the guide straightening frame 5 is fixedly connected to the device frame 1. The tensioning frame assembly 3 includes a support frame 301, a drive motor 302, and a lead screw 303. The drive motor 302 is installed in the middle of the upper end of the support frame 301, and the lead screw 303 is vertically installed at the bottom of the drive motor 302 via a coupling. The drive motor 302 is vertically installed in the middle of the upper end of the support frame 301, and the bottom ends of the left and right sides of the support frame 301 are slidably connected to the support rail 2. The tensioning frame assembly 3 also includes a movable mold 304 and a fixed mold 305. The movable mold 304 is installed at the bottom of the lead screw 303, and the fixed mold 305 is installed directly below the movable mold 304. The fixed mold 305 is fixedly connected to the support frame 301, and the left and right sides of the movable mold 304 are slidably connected to the support rail 2. Both ends are slidably connected to the support frame 301. A servo motor 6 is installed on one side of the bottom of the device frame 1, and a bidirectional lead screw 7 is horizontally installed at the power output end of the servo motor 6 through a coupling. The bottom middle of the fixed mold 305 is threadedly connected to the bidirectional lead screw 7, and the movable mold 304 is threadedly connected to the lead screw 303. When the drive motor 302 drives the lead screw 303 connected to its bottom end to rotate, the movable mold 304 connected to the bottom of the lead screw 303 is pushed to the fixed mold 305 directly below. After the fixed mold 305 and the movable mold 304 fix the left and right ends of the copper tube body 4, the servo motor 6 drives the bidirectional lead screw 7 to rotate horizontally, so that the tensioning frame group 3 holding the copper tube body 4 moves horizontally to both ends along the surface of the support guide rail 2 and the bidirectional lead screw 7, thereby stretching the copper tube body 4.

[0025] In summary, as Figures 1 to 4 As shown, when using the stretching device for copper tube processing, the copper tube body 4 to be stretched is first preheated in the upstream equipment and then transported with the conveying device. It moves horizontally through the middle of the guide straightening frame 5 at one end of the device frame 1, and then passes through the guide tube 502 in the middle of the fixed plate 501, thus entering the stretching frame group 3 set in the middle of the device frame 1.

[0026] Then, by horizontally turning the adjusting screw 504 in the middle of the stabilizer 503, the fixed frame 505 connected to the adjusting screw 504 is horizontally pushed, thereby pushing the straightening wheel 506 on one side of the fixed frame 505 against the side surface of the copper tube body 4.

[0027] After the guide straightening frames 5 at both ends of the device frame 1 are adjusted, the tensioning frame group 3, which is symmetrically arranged on the left and right, is started. Driven by the drive motor 302 in the middle of the upper end of the support frame 301, the lead screw 303 connected to it will rotate axially in the vertical direction, so that the movable mold 304 at the bottom of the lead screw 303 moves along the surface of the support frame 301 and the lead screw 303 towards the fixed mold 305 directly below, thereby clamping the copper tube body 4 in the upper and lower parts and fixing its structure. Then, the servo motor 6 at the bottom of the device frame 1 starts to operate, and at the same time drives the bidirectional lead screw 7 connected to it to rotate horizontally, so that the tensioning frame group 3 connected to it moves to both sides along the surface of the support guide rail 2 and the bidirectional lead screw 7, thereby stretching the copper tube body 4. The processing is then completed.
