Description

Technical Field

[0001] This utility model relates to the field of aluminum tube cutting and processing technology, specifically to an aluminum tube segment cutting device. Background Technology

[0002] With the rapid development of the metal processing industry, aluminum tubes are widely used in various fields due to their lightweight and corrosion-resistant properties. In the process of aluminum tube processing, it is usually necessary to cut the aluminum tubes into sections to obtain the required length. Most of the existing cutting devices are manual or semi-automatic.

[0003] Currently, common cutting devices mainly include clamps, cutters, and cutting length adjustment mechanisms. In practice, a longer aluminum tube is inserted into the clamp, the cutting length is adjusted, the clamp is tightened, and finally, the cutter is fed laterally for cutting. However, this type of cutting equipment has shortcomings: it lacks an automatic unloading function after cutting. This means that when cutting a large number of tubes, manual unloading is required after each cut, which is inconvenient and time-consuming.

[0004] Therefore, this utility model provides an aluminum tube segment cutting device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum tube segment cutting device to solve the problems mentioned in the background technology. This utility model has the function of automatic unloading after aluminum tube segment cutting, which not only reduces labor intensity, but also improves the efficiency of segment cutting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum tube segment cutting device, comprising a base, two uprights fixedly connected to the upper end face of the base, a rotating shaft at the top connected between the two uprights, two V-shaped brackets fixedly connected to the outer peripheral wall of the rotating shaft respectively close to the two uprights and in the same plane, a lifting rod fixedly connected to the bottom and the base on one side of the rotating shaft, a cantilever fixedly connected to the top of the lifting rod, a pressure plate fixedly connected to one end of the cantilever above the rotating shaft, a control assembly for controlling the rotation of the rotating shaft and a cutting limit plate opposite to one end of the rotating shaft on one side of one of the uprights, and a length limiter opposite to the other end of the rotating shaft on one side of the other upright.

[0007] Furthermore, the tops of the two uprights are fixedly connected to positioning sleeves that are sleeved on the outside of the rotating shaft, and the V-shaped bracket is positioned close to the positioning sleeves and its small end is fixedly connected to the rotating shaft.

[0008] Furthermore, the control assembly includes a control motor, a drive gear, and a driven gear. The control motor is fixedly mounted on one side of one of the uprights, and its output shaft is fixedly connected to a drive gear located below an adjacent positioning sleeve. The driven gear is fixedly mounted on the outside of the rotating shaft and meshes with the drive gear.

[0009] Furthermore, the pressure plate is a rectangular plate structure parallel to the rotating shaft, and its upper end face is fixedly connected to the cantilever. The lower end face of the pressure plate is welded with clamping blocks located at both ends.

[0010] Furthermore, the lifting rod is either a control cylinder or a control hydraulic cylinder.

[0011] Furthermore, the length limiter includes a lead screw and a stop plate, with a support plate welded to the outer side of one of the uprights, a positioning plate welded to the upper end face of the support plate, and a lead screw parallel to the rotating shaft threaded through one side of the positioning plate. One side of the stop plate is rotatably connected to one end of the lead screw facing the V-shaped bracket.

[0012] Furthermore, guide sleeves are fitted onto the two diagonal rods on the V-shaped bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, a rotating shaft is provided, and two V-shaped brackets are provided on the outer wall of the rotating shaft. The V-shaped brackets are used to lift and limit the aluminum tube. Then, a pressure plate that can move up and down is provided above the rotating shaft. The pressure plate has the function of pressing the aluminum tube lifted by the V-shaped brackets. After the aluminum tube is cut, the rotating shaft can be controlled to rotate, and the required section of tube can be tilted outward through the V-shaped brackets. Therefore, it has the advantages of making the unloading after cutting more labor-saving and convenient, and greatly improving the efficiency of fixed-section cutting.

[0015] 2. In this utility model, the V-shaped bracket, together with the pressure plate, plays the role of clamping and positioning the aluminum tube. At the same time, as it moves with the rotating shaft, it can also lift the cut aluminum tube for unloading. This setting greatly simplifies the structure of clamping and unloading control and reduces the cost. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: an aluminum tube segment cutting device, including a base 1, a cutter and a feeding structure. The cutter is a common structure with oscillating cutting function. The function of the feeding structure is to guide the aluminum tube so that the aluminum tube can be stably conveyed to the cutting area. Since the cutter and the feeding structure can be directly adopted from the existing technology, this application will not elaborate further.

[0022] In this technical solution, two uprights 2 are fixedly connected to the upper end face of the base 1, and a rotating shaft 3 located at the top is connected between the two uprights 2. Specifically, a positioning sleeve 21 sleeved on the outside of the rotating shaft 3 is fixedly connected to the top of the two uprights 2. The rotating shaft 3 is horizontal, and two V-shaped brackets 5 are fixedly connected to the outer peripheral wall of the rotating shaft 3, which are close to the two uprights 2 and in the same plane. The V-shaped brackets 5 play the role of supporting and limiting the aluminum tube required. The V-shaped brackets 5 are set close to the positioning sleeve 21 and their small ends are fixedly connected to the rotating shaft 3. The large end of the V-shaped brackets 5 faces upward so that it can stably support and limit the aluminum tube. When the rotating shaft 3 rotates to the point where the V-shaped brackets 5 tilt outward, the cut aluminum tube supported by the V-shaped brackets 5 will slide out by its own weight. At this time, a turnover box or turnover rack can be placed on the base 1. The turnover box or turnover rack can directly receive the aluminum tube that slides out from the V-shaped brackets 5.

[0023] Furthermore, a lifting rod 4 is provided on one side of the rotating shaft 3, with its bottom fixedly connected to the base 1. A cantilever 6 is fixedly connected to the top of the lifting rod 4, and a pressure plate 7 located above the rotating shaft 3 is fixedly connected to one end of the cantilever 6. When the lifting rod 4 moves up and down, it can drive the pressure plate 7 to squeeze the aluminum tube inside the V-shaped bracket 5. The lifting rod 4 is either a control cylinder or a control oil cylinder. When in use, the control cylinder or control oil cylinder is connected to the corresponding electromagnetic control valve to control its stroke.

[0024] In this embodiment, a control assembly 8 for controlling the rotation of the rotating shaft 3 is provided on one side of one of the uprights 2. Specifically, the control assembly 8 includes a control motor 81, a drive gear 82, and a driven gear 83. The control motor 81 is fixedly installed on one side of one of the uprights 2, and its output shaft is fixedly connected to the drive gear 82 located below the adjacent positioning sleeve 21. The driven gear 83 is fixedly sleeved on the outside of the rotating shaft 3 and meshes with the drive gear 82. After the control motor 81 is started, it will drive the rotating shaft 3 to rotate through the meshing of the drive gear 82 and the driven gear 83.

[0025] One of the uprights 2 is equipped with a cutting limit plate 9 on one side, which is opposite to one end of the rotating shaft 3. The function of the cutting limit plate 9 is to serve as a reference plate for the cutting blade on the cutter. During cutting, the cutting blade feeds along the outside of the cutting limit plate 9. The other upright is equipped with a length limiter 101 on one side, which is opposite to the other end of the rotating shaft 3. The function of the length limiter 101 is to adjust the length of the aluminum tube cutting, so as to facilitate the segmented cutting function.

[0026] Specifically, the length limiter 101 includes a lead screw 1011 and a baffle 1012. A support plate 22 is welded to the outer side of one of the uprights 2, and a positioning plate 221 is welded to the upper end of the support plate 22. A lead screw 1011 parallel to the rotating shaft 3 is screwed through one side of the positioning plate 221. When the lead screw 1011 is rotated, it will move axially. One side of the baffle 1012 is rotatably connected to the end of the lead screw 1011 facing the V-shaped bracket 5, thereby driving the baffle 1012 to move, so that the distance between the baffle 1012 and the cutting limit plate 9 is adjustable, realizing the function of adjusting the cutting length of the aluminum tube.

[0027] In this embodiment, the pressure plate 7 is a rectangular plate structure parallel to the rotating shaft 3 and its upper end face is fixedly connected to the cantilever 6. The lower end face of the pressure plate 7 is welded with clamping blocks 71 located at both ends. The clamping blocks 71 can reduce the contact area between the pressure plate 7 and the aluminum tube, so that the aluminum tube will not bend or deform when it is clamped.

[0028] In this embodiment, guide sleeves 511 are fitted on the two inclined rods 51 on the V-shaped bracket 5. The guide sleeves 511 facilitate the passage of the aluminum tube's moving shaft through the V-shaped bracket 5. In other words, when the aluminum tube is axially fed onto the V-shaped bracket 5, if there is a slight misalignment between the aluminum tube and the V-shaped bracket 5, the guide sleeves 511 can passively roll to guide the aluminum tube onto the V-shaped bracket 5, which has the advantage of smoother cutting and feeding.

[0029] Working principle: The long aluminum tube is fed into the feeder (the feeder can be selected with at least two sets of feeding structures containing grooved wheels). Under the transmission of the feeder, the aluminum tube moves axially towards the V-shaped bracket 5. When one end of the aluminum tube contacts the guide sleeve 511, the guide sleeve 511 rotates and guides the aluminum tube onto the V-shaped bracket 5. When one end of the aluminum tube abuts against one side of the positioning plate 221, the aluminum tube stops moving. Then, the lifting rod 4 is controlled to retract, the pressure plate 7 descends, and the clamping block 71 clamps the aluminum tube between the two V-shaped brackets 5. The upper end of the cutter is controlled to swing down, and the cutter is in a state of close contact with the outside of the cutting limit plate 9. At this time, the rotating cutter can cut the aluminum tube into sections. After the cutting is completed, the pressure plate 7 is controlled to move away from the aluminum tube, and the control motor 81 is started. Through the meshing of the active gear 82 and the passive gear 83, the rotating shaft 3 is driven to rotate. The V-shaped bracket 5 swings outward and tilts the cut section of the tube outward.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
