DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0026] Example 1

[0027] This embodiment provides an automatic metal pipe drawing device.

[0028] refer to Figure 1 , an automatic metal tube drawing device, including a collaborative robot 1 of the prior art, based on the collaborative robot 1 described in this embodiment, is used to clamp the metal tube to be sharpened and the metal tube to be drawn after sharpening. Specifically, the collaborative robot 1 is equipped with a mechanical arm, which clamps the metal tube by opening and closing the mechanical arm jaws. It should be clear that the mechanical arm jaws need to consider the diameter and length of the metal tube to ensure that the clamping is firm and stable. An automatic metal tube drawing device also includes a base 2, a linear slide 3, a sharpening mechanism 4, a clamping mechanism 5, and a drawing mechanism 6. The base 2 is composed of two parts, including a front end and a terminal end. The front end and the terminal end are electric control cabinets of different heights. The electric control cabinet is used to control all mechanisms on the top of the base 2. The front end is lower than the terminal end. The top of the front end is provided with a sharpening mechanism 4, and the top of the terminal is provided with a linear slide 3. The starting end of the track of the linear slide 3 is fixedly installed with a clamping mechanism 5, and the drawing mechanism 6 is slidably connected to the track. The collaborative robot 1 is arranged on one side of the base 2.

[0029] The pointed mechanism 4 is used to perform pointed treatment on the end of the metal tube. The pointed treatment process is to perform plastic deformation on the end of the metal tube to facilitate the subsequent drawing operation. Specifically, the pointed mechanism 4 processes the end of the metal tube to form a conical or cone-tip structure, which helps to pass through the mold core more easily during the drawing operation, and can ensure that the metal tube maintains a relatively uniform diameter during the entire drawing process. At the same time, the pointed treatment can form a more uniform wall thickness at the end of the metal tube, improve the structural strength of the metal tube, and facilitate the stability of the metal tube in the subsequent drawing operation. The pointed mechanism 4 in this embodiment can be adjusted according to the actual application scenario to adapt to metal tubes of different diameters, and the pointed angle can be adjusted according to different needs to adapt to metal tubes of different shapes and requirements, so that the metal tube automatic drawing device can process metal tubes of various specifications, thereby improving the applicability of the device;

[0030] The clamping mechanism 5 plays the role of fixing and clamping the metal tube in the metal tube automatic drawing device. Specifically, the clamping mechanism 5 clamps the metal tube to ensure that it maintains a fixed position throughout the drawing process, improves the drawing accuracy and stability, and prevents the metal tube from shifting or shaking during the processing. The clamping mechanism 5 needs to provide sufficient clamping force to ensure that the metal tube can be firmly clamped to prevent loosening or sliding during the drawing operation, thereby ensuring the reliability of the entire processing process. The clamping mechanism 5 in this embodiment has an adjustable design to adapt to metal tubes of different diameters. At the same time, the clamping mechanism 5 works in conjunction with the collaborative robot 1 to ensure that the robot can accurately place the metal tube.

[0031] The drawing mechanism 6 is used in the metal tube automatic drawing device to stretch the metal tube so that the diameter is gradually reduced to reach the required size. Specifically, the drawing mechanism 6 applies stretching to the metal tube through the core tooling 8 on the drawing mechanism 6 so that the metal tube is gradually extended and the diameter is reduced. In order to achieve a higher drawing ratio or more precise size requirements, the drawing mechanism 6 in this embodiment can perform multiple drawing passes.

[0032] The linear slide 3 is slidably connected to the drawing mechanism 6, providing support and movement track for the drawing mechanism 6, so that the drawing mechanism 6 can slide smoothly on the linear slide 3, ensuring accuracy and stability during the drawing process. In this embodiment, the track of the linear slide 3 is set on a side wall of the linear slide 3. The purpose of this design is to avoid the drawing mechanism 6 and release space. At the same time, the length of the track in the linear slide 3 can be designed and adjusted as needed to adapt to the drawing processing of metal pipes of different lengths.

[0034] Based on Example 1, this example proposes a specific structure of a metal pipe automatic drawing device.

[0035] A metal tube automatic drawing device includes a core frame 7, which is arranged on the top of a linear slide rail 3. The top of the linear slide rail 3 described in this embodiment is designed to be open, and a suspended bracket is provided on the top of the linear slide rail 3.

The die set on the upper part of the point rolling feed plate 408 is driven to move by the point rolling feed servo shaft 401 to ensure that the die set is completely Close to the rolling wheel 406, a track is set on the top of the rolling feed plate 408, and the track is slidably connected to the rolling angle adjustment jaw 404 and the guide jaw cylinder 405. The end of the rolling angle adjustment rotating cylinder 403 is fixedly connected to the rolling angle adjustment jaw 404 to drive the rolling angle adjustment jaw 404 to rotate. A guide jaw cylinder 405 is set on the opposite side of the rolling angle adjustment jaw 404, and the guide jaw cylinder 405 is connected to the mold cylinder 402.

[0037] The end of the rolling angle adjustment rotating cylinder 403 is fixedly connected to the rolling angle adjustment jaw 404 to drive the rolling angle adjustment jaw 404 to rotate. In this embodiment, the metal tube entering the rolling angle adjustment jaw 404 is locked and rotates with the rotation of the rolling angle adjustment jaw 404. A guide jaw cylinder 405 is arranged on the opposite side of the rolling angle adjustment jaw 404. The guide jaw cylinder 405 is connected to the die-matching cylinder 402. The die-matching cylinder 402 is used to push the guide jaw cylinder 405. After being pushed, the guide jaw cylinder 405 is directly aligned with the rolling wheel guide hole 407 to realize rolling guidance. The rolling angle adjustment jaw 404 and the guide jaw cylinder 405 are both arranged on a track. In this embodiment, the guide jaw cylinder 405 is slidably connected to the track.

[0038] The sharpening mechanism 4 also includes a sharpening wheel 406 fixing frame 9, a sharpening wheel 406, and a sharpening wheel guide hole 407. The sharpening wheel 406 fixing frame 9 is arranged at the top of the front end of the base 2. The sharpening wheel 406 fixing frame 9 is sequentially provided with a sharpening wheel 406 and a sharpening wheel guide hole 407 from the inside to the outside, wherein the feed end of the sharpening angle adjustment jaw 404, the feed end of the guide jaw cylinder 405, the feed end of the sharpening wheel guide hole 407, and the feed end of the sharpening wheel 406 are located on the same horizontal line. The sharpening wheel 406 fixing frame 9 is the supporting structure of the entire sharpening mechanism 4 and is arranged at the top of the front end of the base 2. Its function is to provide stable support to ensure that the sharpening wheel 406 and the sharpening wheel guide hole 407 can maintain a stable position during the sharpening process; the sharpening wheel 406 is used to sharpen the metal tube, and the feed end of the sharpening wheel 406 is located on the same horizontal line and aligned with other components to ensure that the metal tube can be evenly subjected to force during the sharpening process to achieve the sharpening effect; the sharpening wheel guide hole 407 is a hole on the sharpening wheel 406 fixing frame 9, and its function is to provide guiding support for the sharpening wheel 406, which helps to ensure that the sharpening wheel 406 maintains the correct position and angle during the sharpening process, making the sharpening process more precise. In this embodiment, a plurality of sharpening wheel guide holes 407 are arranged on a plate body, and the plate body is fixed on the sharpening wheel 406 fixing frame 9.

[0039] In this embodiment, there are multiple groups of the sharpening wheels 406, and the multiple groups of the sharpening wheels 406 are arranged in sequence in the sharpening wheel 406 fixing frame 9, and the mold sizes of the multiple groups of the sharpening wheels 406 are different. There are multiple sharpening wheel guide holes 407, and the multiple sharpening wheel guide holes 407 are arranged in sequence on the sharpening wheel 406 fixing frame 9, and the apertures of the multiple sharpening wheel guide holes 407 are different.

[0040] Since the diameter of the metal tube may vary, different diameters of the sharpening wheels 406 are required to accommodate this variation. Each set of sharpening wheels 406 can be selected according to the diameter of the metal tube to ensure that the metal tube can be properly processed during the sharpening process.

[0041] Different processing requirements may require different shapes of rolling points. By designing multiple groups of rolling wheels 406, each group of rolling wheels 406 has different die sizes, the shape of the metal tube rolling point can be flexibly adjusted.

[0042] Specifically, using multiple sets of sharpening wheels 406, each set of sharpening wheels 406 is specially designed for metal pipes of specific specifications, which can improve the processing accuracy. In addition, sharpening wheels 406 of different diameters and shapes can make the processing process more efficient and avoid the need to frequently replace sharpening wheels 406.
