Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, and more specifically, to a cutting device used for copper tube processing. Background Art

[0002] Copper tube is also called red copper tube. It is a kind of non-ferrous metal tube, which is a pressed and drawn seamless tube. After the copper tube is cast, it needs to be cut when it is processed into the target pipe, so a cutting device is needed.

[0003] For example, the existing related patent CN218799471U has been retrieved, which discloses a cutting device for pipe processing. The prior art is provided with a cutting table, a slide groove, an intermittent pushing mechanism, a clamping assembly, a supporting assembly and a mobile cutting mechanism. The utility model realizes the action of first clamping the copper pipe and then cutting it to a fixed length, which is convenient for cutting the copper pipe to a fixed length.

[0004] However, the inventors have found that the following problems exist when using the prior art: in the prior art, when cutting the copper tube, the driving clamping assembly needs to be moved in order to transport the copper tube, and the length of the copper tube is limited by the displacement length of the clamping assembly, so that the clamping assembly can only cut the copper tube that is smaller than the displacement distance of the clamping assembly. However, in the actual copper tube cutting process, the length of the copper tube is generally longer. As a result, when cutting the longer copper tube in the prior art, after the clamping assembly is moved to the side close to the cutting table, the clamping assembly returns to the initial position, loosens the copper tube, and then pushes the other end of the copper tube onto the cutting table, and then transports the copper tube by controlling the clamping assembly. This method has more complicated operating steps when cutting the copper tube, which reduces the cutting efficiency of the copper tube. In response to the above problems, the inventors have designed a cutting device for copper tube processing. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-4 , the utility model provides the following technical solutions:

[0022] Specifically, it refers to a cutting device for copper tube processing, including a base plate 1, an L-shaped frame 2 is fixedly installed on the upper surface of the base plate 1, a cylinder 3 is fixedly installed on the horizontal plate of the L-shaped frame 2, the lower end of the telescopic rod of the cylinder 3 slides through the lower surface of the horizontal plate of the L-shaped frame 2, and a cutting component 4 is provided at the lower end of the telescopic rod of the cylinder 3. The cutting component 4 is a known technology in the existing patent: CN218799471U, which will not be described in detail here. A cutting table 5 is fixedly installed on the upper surface of the base plate 1, and a cutting groove is opened on the cutting table 5. The cutting table 5 and the cutting component 4 are in the same vertical position. When cutting the copper tube, one end of the copper tube is transported to the cutting table 5, and the cylinder 3 pushes the cutting component 4 to move downward, so that the cutting component 4 can cut the copper tube.

[0023] A support seat 6 is fixedly installed on the upper surface of the base plate 1, an arc frame 7 is fixedly installed on the upper surface of the support seat 6, a conveying assembly is provided on the upper surface of the support seat 6, and the conveying assembly includes a U-shaped seat 8, a rotating shaft 9 is rotatably connected between two vertical plates of the U-shaped seat 8, and a conveying wheel 10 is fixedly sleeved on the outer surface of the rotating shaft 9.

[0024] The top of the conveying wheel 10 is at the same horizontal position as the upper surface of the cutting table 5. When the copper tube is placed on the conveying wheel 10, the other end of the copper tube can extend to the cutting table 5. The interior of the support seat 6 is hollow, and a connecting groove 12 connected to the interior of the support seat 6 is opened on the upper surface of the support seat 6. One end of the rotating shaft 9 rotates to penetrate the outer surface of the U-shaped seat 8, and the end of the rotating shaft 9 located outside the U-shaped seat 8 is fixedly sleeved with a pulley 11. A movable shaft 14 is rotatably connected to the inner wall of the support seat 6. The outer surface of the movable shaft 14 is also fixedly sleeved with a pulley 11. A transmission belt 13 is connected between the two pulleys 11. The transmission belt 13 is arranged in the connecting groove 12. A worm wheel 15 is fixedly sleeved on the outer surface of the movable shaft 14. A worm 16 is meshed and connected at the bottom of the worm wheel 15. One end of the worm 16 is rotatably connected to the inner wall of the support seat 6. A servo motor 17 is fixedly connected to the outer surface of the support seat 6. The output shaft of the servo motor 17 rotates and penetrates into the support seat 6 and is fixedly connected to the other end of the worm 16.

[0025] When the copper tube is placed on the conveying wheel 10, the servo motor 17 is started, and the output shaft of the servo motor 17 synchronously drives the worm 16 to rotate, so that the worm 16 meshes and drives the worm wheel 15 to rotate, and the movable shaft 14 rotates synchronously under the drive of the worm wheel 15, so the rotating shaft 9 rotates under the drive of the two pulleys 11, so that the conveying wheel 10 rotates, and the copper tube placed on the conveying wheel 10 can be conveyed at this time. In this way, there is no need to drive the copper tube to move synchronously. No matter how long the copper tube is, the conveying structure can convey the copper tube, which further ensures the effect of cutting the copper tube, and also ensures the cutting efficiency of the copper tube.

[0026] More preferably, a friction ring is fixedly sleeved on the outer surface of the conveying wheel 10 to increase the friction between the conveying wheel 10 and the copper tube, thereby ensuring the stability of the conveying wheel 10 when conveying the copper tube.

[0027] The inner side of the arc frame 7 is also provided with three conveying components, which are arranged on the inner side of the arc frame 7 in a circular array. Three contraction chambers 18 are opened in the arc frame 7, and the three contraction chambers 18 are respectively arranged on the side close to the three conveying components. The U-shaped seat 8 in the arc frame 7 is fixedly connected to a connecting slide 19 on the surface close to the inner side of the arc frame 7, and the other end of the connecting slide 19 slides through the contraction chamber 18. A limiting slide 20 is fixedly connected to one end of the connecting slide 19 located in the contraction chamber 18, and the limiting slide 20 slides in the contraction chamber 18, and the limiting slide 20 is fixedly connected to the inner wall of the contraction chamber 18. A tension spring 21 is connected, and the tension spring 21 is movably sleeved on the outer surface of the connecting slide bar 19. When the copper tube is placed on the conveying wheel 10 on the support seat 6, the conveying wheels 10 of the other three conveying components are in contact with the outer surface of the copper tube, so that the connecting slide bar 19 can push the limiting slide plate 20 to slide in the contraction cavity 18, and the tension spring 21 is stretched at the same time. When the connecting slide bar 19 stops moving, the tension spring 21 will form a pulling force on the limiting slide plate 20, so that the conveying wheel 10 squeezes the outer surface of the copper tube, thereby completing the fixation of the copper tube, avoiding the problem of deviation of the copper tube during transportation as much as possible, and further ensuring the accuracy of copper tube cutting.

[0028] The working principle of the cutting device for copper tube processing provided by the utility model is as follows: when the copper tube is placed on the conveying wheel 10, the servo motor 17 is started, and the output shaft of the servo motor 17 synchronously drives the worm 16 to rotate, so that the worm 16 meshes and drives the worm wheel 15 to rotate, and the movable shaft 14 rotates synchronously under the drive of the worm wheel 15, so the rotating shaft 9 rotates under the drive of the two pulleys 11, thereby causing the conveying wheel 10 to rotate, and the copper tube placed on the conveying wheel 10 can be conveyed.
