Description

Technical Field

[0001] This utility model relates to the field of aluminum tube processing technology, and more specifically, to a high-precision aluminum tube cold-drawing concentric guide device. Background Technology

[0002] Cold drawing is a material processing technique. For metal materials, cold drawing refers to drawing the material at room temperature in order to achieve a certain shape and mechanical properties. Compared with thermoforming, cold-drawn products have advantages such as higher dimensional accuracy and better surface finish.

[0003] In practical use, when cold drawing aluminum tubes, the ends of the tubes may wobble and be susceptible to uneven stress, causing the tubes to bend or deform in a serpentine manner, which affects the efficiency and accuracy of subsequent cold drawing. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-precision aluminum tube cold drawing concentric guide device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision aluminum tube cold-drawing concentric guiding device includes a work frame. A mold is fixedly connected to the top of the work frame. A servo motor is fixedly connected to one side of the work frame. A lead screw is fixedly connected to the output end of the servo motor. The outer side of the lead screw is rotatably connected to the inner side of the work frame. A concentric guiding mechanism is provided on one side of the work frame. The concentric guiding mechanism includes three supports. The bottom end of each support is fixedly connected to the upper surface of the work frame. The three supports are arranged sequentially on one side of the work frame. A baffle plate 1, a baffle plate 2, and a baffle plate 3 are fixedly connected to the top of each of the three supports. The baffle plates 1, 2, and 3 are arranged sequentially on the work frame. On one side of the work frame, multiple guide rollers are rotatably connected to the inner sides of the first, second, and third baffles. The multiple guide rollers are arranged in a circular array inside the first, second, and third baffles. Two brackets are fixedly connected to the upper surface of the work frame. A rotating tube is rotatably connected to the outer side of the brackets. Multiple toothed grooves are opened on the outer side of the rotating tube. Multiple cleaning rollers are rotatably connected to the inner side of the rotating tube. The cleaning rollers are arranged in a circular array inside the rotating tube. A servo motor is fixedly connected to the top of one of the brackets. A gear is fixedly connected to the output end of the servo motor. One side of the gear meshes with the inner side of the toothed groove. A positioning mechanism is provided on the upper surface of the work frame.

[0007] By adopting the above technical solution: the aluminum tube can be gradually guided by the concentric baffle plate one, baffle plate two and baffle plate three, and multiple guide rollers can be used to guide the aluminum tube by rolling friction, so that the aluminum tube remains stable when entering the mold for cold drawing. In addition, the tooth groove and multiple cleaning rollers can be used to clean the aluminum tube in a cycle, effectively avoiding the residue of waste residue on the surface of the aluminum tube.

[0008] As a further description of the above technical solution: the positioning mechanism includes a sliding base, the outer side of the sliding base is slidably connected to the inner side of the work frame, the inner side of the sliding base is threadedly connected to the outer side of the lead screw, three rollers are rotatably connected to the lower surface of the sliding base, a fixed frame is fixedly connected to the top of the sliding base, a lower pressure frame is fixedly connected to the inner side of the fixed frame, and multiple electric push rods are fixedly connected to the top of the fixed frame. One end of the electric push rod passes through the inner side of the fixed frame and extends into the interior of the fixed frame, and an upper pressure frame is fixedly connected to one end of the electric push rod. Multiple anti-slip strips are fixedly connected to the inner sides of the lower pressure frame and the upper pressure frame.

[0009] By adopting the above technical solution: multiple electric push rods push the upper pressure frame to press down on the aluminum tube, so that the aluminum tube is fully clamped and positioned by the lower pressure frame and multiple anti-slip strips on the inner side of the upper pressure frame, and sufficient tension is applied to the aluminum tube.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up a concentric guiding mechanism, compared with the existing technology, the aluminum tube is gradually guided and corrected by three concentrically set baffles 1, 2 and 3. The rotation of the guide roller reduces frictional resistance, effectively suppresses the swaying and jumping of the aluminum tube before entering the mold, and combines multiple rotating tubes and cleaning rollers to rotate and clean the aluminum tube, remove foreign objects from the surface of the aluminum tube, and improve the stability and precision of the aluminum tube in the cold drawing process.

[0012] 2. By setting up a positioning mechanism, compared with the existing technology, the lower pressure frame, upper pressure frame and multiple anti-slip strips act simultaneously on the end of the aluminum tube to form a two-point constraint, eliminate the initial deviation and improve the stability and reliability of the drawing process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The embodiments disclosed in this application are as follows: Figures 1-6The high-precision aluminum tube cold drawing concentric guiding device shown includes a work frame 1. A mold 2 is fixedly connected to the top of the work frame 1. A servo motor 3 is fixedly connected to one side of the work frame 1. A lead screw 4 is fixedly connected to the output end of the servo motor 3. The outer side of the lead screw 4 is rotatably connected to the inner side of the work frame 1. A concentric guiding mechanism is provided on one side of the work frame 1. The concentric guiding mechanism includes three supports 5. The bottom end of the supports 5 is fixedly connected to the upper surface of the work frame 1. The three supports 5 are arranged sequentially on one side of the work frame 1. A baffle 6, a baffle 7, and a baffle 8 are fixedly connected to the top of the three supports 5 respectively. The baffles 6, 7, and 8 are arranged sequentially on one side of the work frame 1. Multiple guide rollers 9 are rotatably connected to the inner side of each of the baffles 6, 7, and 8. The multiple guide rollers 9 are arranged in a circular array inside the baffles 6, 7, and 8. Two supports 10 are fixedly connected to the upper surface of the work frame 1. A rotating tube 11 is rotatably connected to the outer side of the second bracket 10. Multiple toothed grooves 12 are opened on the outer side of the rotating tube 11. Multiple cleaning rollers 13 are rotatably connected to the inner side of the rotating tube 11. The cleaning rollers 13 are arranged in a circular array inside the rotating tube 11. A servo motor 14 is fixedly connected to the top of one of the second brackets 10. A gear 15 is fixedly connected to the output end of the servo motor 14. One side of the gear 15 meshes with the inner side of the toothed groove 12. A positioning mechanism is set on the upper surface of the work frame 1. Multiple baffles 3 8, baffle 2 7 and baffle 1 6 guide one end of the aluminum tube. Multiple guide rollers 9 are used to assist the aluminum tube in guiding, reducing the friction between the aluminum tube and baffles 1 6, baffle 2 7 and baffle 3 8, so that the aluminum tube remains stable during the cold drawing process of entering the mold 2, improving the accuracy of the cold drawing of the aluminum tube. Combined with the servo motor 2 14 and gear 15, the rotating tube 11 and toothed groove 12 are meshed and driven, so that the multiple cleaning rollers 13 can clean the surface of the aluminum tube.

[0023] Reference Figure 1 and Figure 4 As shown, the positioning mechanism includes a sliding base 16, the outer side of which is slidably connected to the inner side of the work frame 1, and the inner side of which is threadedly connected to the outer side of the lead screw 4. Three rollers 17 are rotatably connected to the lower surface of the sliding base 16. A fixed frame 18 is fixedly connected to the top of the sliding base 16. A lower pressure frame 19 is fixedly connected to the inner side of the fixed frame 18. Multiple electric push rods 20 are fixedly connected to the top of the fixed frame 18. One end of the electric push rod 20 passes through the inner side of the fixed frame 18 and extends into the interior of the fixed frame 18. An upper pressure frame 21 is fixedly connected to one end of the electric push rod 20. Multiple anti-slip strips 22 are fixedly connected to the inner sides of the lower pressure frame 19 and the upper pressure frame 21. The upper pressure frame 21 is pushed up and down inside the fixed frame 18 by the multiple electric push rods 20, so that the upper pressure frame 21 and the lower pressure frame 19, together with the multiple anti-slip strips 22, can squeeze and position one end of the aluminum tube. The three rollers 17 are then used to assist the sliding base 16 in moving smoothly.

[0024] The working principle of this utility model is as follows: When cold drawing aluminum tubes, one end of the aluminum tube is first inserted into the inside of the baffle plate 3 8. Then, multiple guide rollers 9 on the inner sides of the baffle plate 3 8, baffle plate 2 7, and baffle plate 1 6 guide the outer side of the aluminum tube, guiding it so that one end of the aluminum tube approaches the inner side of the mold 2. After the aluminum tube passes through the inner side of the mold 2, one end of the aluminum tube is placed inside the lower pressure frame 19 and the upper pressure frame 21. Then, multiple electric push rods 20 are activated to push the upper pressure frame 21 to press down on the aluminum tube. Multiple anti-slip strips 22 on the inner sides of the lower pressure frame 19 and the upper pressure frame 21 clamp and position the upper and lower sides of the aluminum tube. The servo motor 13 is started to drive the lead screw 4 to perform threaded transmission on the sliding base 16. Combined with the three rollers 17 at the bottom of the sliding base 16, it assists in sliding smoothly inside the work frame 1. During the process of the aluminum tube passing through the mold 2, the servo motor 214 drives the gear 15 to mesh with the multiple tooth grooves 12 on the outside of the rotating tube 11, so that the rotating tube 11 can rotate outside the two supports 210. The multiple cleaning rollers 13 on the inside of the rotating tube 11 can roll and clean the outside of the aluminum tube, cleaning the waste residue on the surface of the aluminum tube. Then, the aluminum tube is pulled by the sliding base 16 to be cold drawn by the mold 2.
