Description

Technical Field

[0001] This utility model relates to the technical field of aluminum tube processing equipment, specifically to an aluminum tube cold drawing processing equipment. Background Technology

[0002] Cold drawing is a metal pressure processing method, and it is an important method that cannot be replaced by other processing techniques. This important position is determined by the characteristics and applications of cold drawing. The characteristic of cold drawing is that external force is applied to the front end of the metal being drawn, pulling the metal billet out of a die hole smaller than the cross-section of the metal billet, thereby increasing its length and reducing its cross-section. It is often used to produce products with very small cross-sectional dimensions, such as thin metal wires, thin metal tubes, and steel wires.

[0003] Chinese Patent No. CN112792146A discloses an automatic aluminum tube cold drawing processing equipment, including a base. The base is characterized by having a feeding box on it, a feeding device below the feeding box, a transferring device below the feeding device, a round rod on it, a moving device connected to one end of the round rod, a supporting structure at the other end of the round rod, a shrinking plate on it, a shrinking hole on the shrinking plate, the end of the shrinking hole near the transferring device being tapered, and a tube pulling device on it, located at one end of the shrinking plate and the transferring device at the other end of the shrinking plate.

[0004] However, in the above solutions, after the cold drawing process, it is impossible to bundle and organize the processed materials, which consumes a lot of manpower and time and reduces work efficiency. Therefore, it is necessary to provide an automatic aluminum tube cold drawing processing equipment to solve the above technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum tube cold drawing processing equipment. This equipment includes a conveying device and a cold drawing device. A cold drawing mold is provided between the conveying device and the cold drawing device. The conveying device transports the aluminum tube to be processed to the cold drawing device. The end of the aluminum tube passes through the cold drawing mold and is clamped by a clamping device on the cold drawing device. The cold drawing device applies a traction force to the aluminum tube. A binding device is connected to the cold drawing device, and the cold-drawn aluminum tube falls onto the binding device. The binding device includes a binding frame and a binding base plate. The aluminum tube is located on the binding frame, and the binding base plate is located at the end of the binding frame. A circular opening is provided on the binding base plate, and a rotatable annular disc is connected to the binding base plate. A cable tie is shaft-connected to the annular disc, and binding tape is wound on the cable tie. When the annular disc rotates, it drives the cable tie to move in a circular motion around the aluminum tube. Simultaneously, the cable tie rotates on its own axis, causing the binding tape on the cable tie to wrap around the aluminum tube.

[0006] Furthermore, the binding base plate is provided with four rotating wheels, each with an annular groove on its circumference. The edge of the annular disc is engaged in the annular groove, and there are protruding teeth on the outer circumference of the annular disc. The rotating wheel meshes with the annular disc.

[0007] Furthermore, a drive shaft passes through the annular disc, with the outer end of the drive shaft docking with the cable tie disc. A small gear is fixed to the inner end of the drive shaft, and an annular gear groove is provided on the binding base plate. The small gear is located in the gear groove, and the inner wall of the gear groove is provided with internal convex teeth.

[0008] Furthermore, the cold drawing device includes a cold drawing machine connected to two linear tracks, one of which is connected to a guide plate. The guide plate is moved as the cold drawing machine moves on the track.

[0009] Furthermore, the guide plate is a flat plate with a triangular structure, and a sleeve is connected to the guide plate. Two perpendicular levers are fixedly connected to the sleeve. A lever is provided on the drawing machine. When the cold drawing machine moves, the lever contacts the lever, causing the guide plate to rotate.

[0010] Furthermore, two lubricating oil tanks are fixedly connected to both sides of the cold drawing die, and the lubricating oil tanks are connected to oil outlet pipes. A collection box is connected to the bottom of the cold drawing die.

[0011] Furthermore, the cold drawing die includes a die shell, and a forming disc is detachably connected to the center of the die shell, with die holes provided on the forming disc.

[0012] Furthermore, the conveying device includes a conveying base plate, a placement rack is provided on the conveying base plate, a cleaning tank is provided below the placement rack, a cleaning pipe is provided on the cleaning tank, and a nozzle is connected to the end of the cleaning pipe.

[0013] Compared with existing technologies, the advantages of this invention are: it can clean impurities from the surface of aluminum tubes and achieve a bundling effect. Specifically, the aluminum tubes are placed on a rack to clean surface impurities. Then, an electric push rod sequentially transfers the aluminum tubes to a conveying device, which transports them to a cold-drawing device for cold drawing. Before cold drawing, the aluminum tubes are lubricated. Then, the cold-drawing machine, pulled by a chain, engages with the cold-drawing die and clamps the aluminum tube. The dual-axis motor is started, and the cold-drawing machine moves backward to perform the cold drawing process. After cold drawing, the tubes can be transferred to a bundling device along a guide plate. At this point, the bundling machine is pushed, and it can be linked with the dual-axis motor to achieve a bundling effect. This device saves manual labor and increases work efficiency.

Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] See Figure 1-8 As shown, the present invention provides an aluminum tube cold drawing processing equipment, including a conveying device located at the starting position, a cold drawing device at the end of the conveying device, and a cold drawing mold between the conveying device and the cold drawing device. The conveying device transports the aluminum tube so that the end of the aluminum tube passes through the cold drawing mold, and then the cold drawing device clamps and positions the end of the aluminum tube. As the cold drawing device moves away from the cold drawing mold, it provides traction force to the aluminum tube, driving the aluminum tube to pass through the cold drawing mold, thereby realizing the cold drawing of the aluminum tube.

[0026] The conveying device 1 includes a conveying base plate 11, on which a placement rack 13 is mounted. The upper placement surface of the placement rack 13 has a certain inclination angle, and a slot is provided on the placement surface of the placement rack 13. The aluminum tubes to be cold-drawn are placed in the slot, preventing them from sliding off the placement rack 13. The aluminum tubes are arranged sequentially along the inclination direction of the placement surface of the placement rack 13. A vertically upward electric push rod 16 is mounted on the conveying base plate 11, located between two placement racks 13. An L-shaped plate is fixedly connected to the upper end of the electric push rod 16. The L-shaped plate is horizontally positioned, and the upward extension of the electric push rod 16 can lift the aluminum tubes on the placement rack 13 upward. The L-shaped plate can also limit the movement of the aluminum tubes upward at a time. An aluminum tube is lifted up. After the aluminum tube moves upward and disengages from the slot, the width of the bottom support surface of the L-shaped plate is smaller than the diameter of the aluminum tube. Therefore, the aluminum tube will roll in the direction of the placement surface. An inclined rod 14 is provided on the side of the placement rack 13. The lifted aluminum tube can slide down along the inclined rod 14. A cleaning tank 12 is provided below the placement rack 13. The cleaning tank 12 is rectangular and contains an acidic liquid of appropriate concentration. Two cleaning pipes 15 are provided on one side of the cleaning tank 12. The two cleaning pipes 15 are positioned corresponding to the placement rack 13. Each pipe is equipped with a high-pressure nozzle. The nozzle of the high-pressure nozzle can be directly aimed at the aluminum tube on the placement rack 13 to remove foreign objects from the surface of the aluminum tube.

[0027] Three rubber rollers 21 are mounted on the conveyor base plate 11. Each roller 21 is connected to the conveyor base plate 11 via two upright plates. The three rollers 21 are arranged in a straight line, and a recessed area is provided in the middle of each roller 21, extending along the circumference of the roller 21. When the aluminum tube is separated from the placement rack 13, the aluminum tube can rest on the recessed area of ​​the roller 21. The foremost roller 21 is connected to a drive motor 22, which controls the rotation of the roller 21, thereby providing power for the conveying of the aluminum tube. Two vertical rods are provided at the ends of the conveyor base plate 11, each with bristles 31. There is a certain distance between the two vertical rods, allowing the aluminum tube to pass through between them. One of the vertical rods is a positioning vertical rod, and the other is a clamping vertical rod. The lower end of the positioning vertical rod is connected to a shaft, which passes through the conveyor base plate 11. The lower end of the shaft is connected to a drive motor via a conveyor belt. The clamping vertical rod is slidably connected to the conveyor base plate 11. For example, a slider is fixed at the lower end of the clamping vertical rod, and a rail groove is provided on the conveyor base plate 11. The slider fits into the rail groove, and a spring is connected between the end of the slider and the end of the rail groove. The spring can provide elastic force to the slider to approach the positioning vertical rod, thereby adjusting the distance between the two vertical rods so that the two vertical rods have a certain clamping force on the aluminum tube. When the positioning vertical rod rotates, it can also transmit power to the aluminum tube. The rotation of the brush 31 can further remove foreign objects and pickling liquid from the aluminum tube.

[0028] It should be noted that before conveying the aluminum tube, the end of the aluminum tube needs to be narrowed so that the end of the aluminum tube can pass through the cold drawing die, and also facilitates the cold drawing device 5 to clamp the aluminum tube at this position.

[0029] The cold drawing die 4 is connected to the cold drawing device 5. The cold drawing die 4 includes a die shell. A forming plate is detachably connected to the center of the die shell. The forming plate is provided with a die hole 41. The die hole 41 is a tapered hole, that is, the diameter of one end of the die hole is larger than the diameter of the other end. It can guide the end of the aluminum tube through the die hole 41. When it is necessary to replace the die hole 41, the forming plate can be disassembled and replaced.

[0030] The cold drawing die 4 has two lubricating oil tanks 42 fixedly connected to both sides. The lubricating oil tanks 42 are connected to oil outlet pipes 43. The two lubricating oil tanks 42 are symmetrically arranged on both sides with the central axis of the cold drawing die 4. Lubricating oil can be applied to the surface of the aluminum tube through the lubricating oil tanks 42 to reduce the friction between the aluminum tube and the inner ring of the die hole 41.

[0031] In addition, a rectangular collection box 44 is connected below the cold drawing mold 4. The collection box 44 is used to collect the fallen lubricant and prevent it from contaminating the ground.

[0032] After the end of the aluminum tube passes through the die hole 41 on the cold drawing die 4, the cold drawing device 5 needs to provide traction force to the aluminum tube. The cold drawing device 5 includes a drawing machine 6, which is connected to two linear rails 51. Several pairs of tie rods are connected between the two rails 51. One end of the rail 51 is fixedly connected to the cold drawing die 4. The drawing machine can move along the length of the rail, providing traction force to the aluminum tube during this process. The drawing machine 6 is wrapped with a frame 61. Four wheels are provided under the frame 61, and the wheels are rolledly connected to the rails 51. The frame 61 is provided with a clamping device and a clamping port. The end of the aluminum tube can be inserted through the clamping port and then clamped by the clamping device. The clamping device adopts existing technical solutions, such as a clamping structure or a gripping structure. After the end of the aluminum tube is clamped, the frame is controlled to move away from the cold drawing mold. Specifically, a traction block 63 is fixed on the lower surface of the frame 61. Two gears are set below the frame 61, each gear is connected to a drive mechanism 73, and each drive mechanism is connected to the bottom surface of the track. A chain 7 is also set. The two ends of the chain 7 pass around the gears on the corresponding sides and then connect to the traction block 63. When one of the drive mechanisms is working, it can drive the frame 61 to move away from the cold drawing mold, and the cold drawing process of the aluminum tube begins. After the cold drawing process of the aluminum tube is completed, the other drive mechanism can control the frame 61 to move closer to the cold drawing mold, so that the frame 61 is reset, which is convenient for subsequent cold drawing processes of the aluminum tube.

[0033] A guide plate 52 is connected to one end of the track 51. The guide plate 52 is a flat plate with a triangular structure. Its lower end is a sleeve 521. Two perpendicular levers 523 are fixedly connected to the sleeve 521. A lever 66 is provided on the front end of the drawing machine 6. When the lever 66 on the drawing machine 6 contacts the lever 523, the guide plate 52 can rotate. When the drawing machine 6 moves closer to the cold drawing die, the deflector 66 at its front end contacts the lever 523, generating a forward force. Since the sleeve 521 can rotate inside the sleeve 522, which is fixed on the track, the guide plate 52 can move on the horizontal plane under the push of this force, eventually positioning the guide plate 52 to the side of the track 51 and parallel to it. When the drawing machine 6 moves away from the cold drawing die, the deflector 66 at its front end contacts another lever 523, generating a backward force. At this time, the guide plate 52 moves to a position where its length direction is perpendicular to the track 51 and above the track 51, with the top side of the guide plate being inclined. In this state, the aluminum tube after cold drawing can slide down along the guide plate 52. By cooperating with the deflector 66 and the rotation mechanism of the drawing machine 6, the aluminum tube can be guided.

[0034] A strapping device is connected to one of the tracks of the cold drawing device. The strapping device includes a strapping frame 91, which is a rectangular frame structure. There are several rubber rollers 92 on the strapping frame 91, and each rubber roller 92 can rotate. When the cold-drawn aluminum tube falls onto the strapping frame 91, it can push the aluminum tube. A strapping machine 8 is set at the end of the strapping frame 91 away from the cold drawing mold. The strapping machine 8 is slidably connected to the track 51. A groove matching the track 51 is provided on one side of the strapping machine 8. At the same time, a slide rail is connected to the side of the track 51. The groove can be locked on the slide rail. Therefore, the strapping machine 8 can slide freely on the slide rail. A limit device is provided on the slide rail to ensure that the strapping machine 8 accurately reaches the strapping position.

[0035] The strapping machine 8 includes a strapping base plate 81, which is a square flat plate structure with a circular opening in the middle. The end of the cold-drawn aluminum tube can be inserted through this opening. Four rotating wheels 82 are provided on the strapping base plate 81, and each rotating wheel 82 is connected to the strapping base plate 81 through a rotating shaft, so that the rotating wheel 82 can rotate. An annular disk 83 is also provided on the strapping base plate 81, which is located between the four rotating wheels 82 and is connected to all four rotating wheels 82. An annular groove is provided on the circumference of each rotating wheel 82, and the edge of the annular disk 83 is engaged in the annular groove. The outer circumference of the annular disk 83 is provided with protruding teeth, and the annular groove of the rotating wheel 82 is provided with mating teeth. At this time, the rotating wheel 82 and the annular disk 83 are meshed. When a rotating wheel 82 rotates, it can drive the annular disk 83 to rotate.

[0036] A through-shaft hole is provided on the annular disk 83, through which a drive shaft passes. A cable tie tray 84 is fixed to the outer end of the drive shaft, and a pinion is fixed to the inner end of the drive shaft. An annular gear groove 85 is provided on the binding base plate 81, and the gear groove is coaxial with the opening of the binding base plate 81. After the annular disk 83 is connected to the four rotating wheels 82, the pinion is located in the gear groove 85 on the binding base plate 81. The inner wall of the gear groove 85 is provided with internal protruding teeth, which mesh with the pinion. When the annular disk 83 rotates, the drive shaft moves in a circular motion. At this time, the pinion moves in the gear groove 85, so the drive shaft will rotate, thereby driving the cable tie tray 84 to rotate. The cable tie tray 84 is wrapped with binding tape.

[0037] When controlling the rotation of the annular disk 83, a turbine is connected to a certain rotating wheel 82, and a worm gear is connected to a drive mechanism on the cold drawing device. When the turbine and the worm gear are engaged, the drive mechanism can control the rotation of the rotating wheel 82, thereby driving the annular disk 83 and the cable tie tray 84 to rotate.

[0038] You can also manually control the rotation of a certain wheel 82, for example, by connecting the rocker arm 85 to the wheel 82. At this time, you can also control the rotation of the moving ring disk 83 and the cable tie disk 84.

[0039] Cable ties are wound around the cable tie reel 84. Initially, one end of the cable tie is wound around the cable tie reel 84, and the other end hangs vertically under the action of gravity. When the disc 83 starts to rotate under the drive of the wheel, the cable tie reel 84 makes a circular motion. Since the cable tie reel 84 is linked to the binding base plate 81, the cable tie reel 84 also rotates on its own axis. The cable tie reel 84 starts to release the cable tie during its rotation. After the cable tie reel 84 moves around the aluminum tube, the cable tie forms a wrap around the aluminum tube. At this time, the hanging end of the cable tie is connected to the part wrapped around the cable tie reel 84. Then the cable tie needs to be cut to complete the binding of the aluminum tube.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
