Description

Technical Field

[0001] This utility model relates to the field of aluminum tube processing equipment, and in particular to an automatic aluminum tube shrinking device. Background Technology

[0002] The production process of aluminum tubes includes heat treatment of aluminum columns, hot sawing, pultrusion molding, and straightening. After pultrusion molding, the aluminum tubes also need to undergo a drawing process to improve their precision. In existing equipment, the aluminum tubes need to be pulled through the drawing device by a tube pulling mechanism, which requires the ends of the aluminum tubes to be retracted to facilitate clamping and pulling by the tube pulling mechanism. However, current retraction equipment is manual, which not only occupies manpower but also easily causes the connection between the front and back ends of the aluminum tubes in the drawing device to be unsmooth, affecting the normal operation of the preceding and following processes. Therefore, there is an urgent need for an automatic aluminum tube retraction device to solve the above problems. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an automatic aluminum tube shrinking device.

The drive assembly is connected to the rotating base and is used to drive the rotating base to rotate. The directional disc is installed on the periphery of the rotating base and has several directional grooves arranged circumferentially thereon, with the directional grooves arranged radially along the center of the directional disc. The die-cutting molds are set in the directional grooves and abut against the rotating base. The guide disc is installed on the rotating base and is movably connected to the die-cutting molds. The aluminum tube passes through the die-cutting molds. When the drive assembly drives the rotating base to rotate in the forward direction, it drives the die-cutting molds to move inward to compress and deform the aluminum tube; or when the drive assembly drives the rotating base to rotate in the reverse direction, it drives the die-cutting molds to move outward so that the aluminum tube moves between the die-cutting molds.

[0026] Reference Figures 1 to 2 An automatic aluminum tube shrinking device includes a drive assembly 10, a rotating seat 20, a directional disc 30, a guide disc 40, and several die-cutting molds 50.

[0027] Drive assembly 10 is connected to rotating seat 20 and is used to drive rotating seat 20 to rotate;

[0028] The directional disk 30 is mounted on the periphery of the rotating seat 20 and has a plurality of directional grooves 31 arranged circumferentially thereon. The directional grooves 31 are arranged radially along the center of the directional disk 30.

[0029] The die 50 is set in the directional groove 31 and abuts against the rotating seat 20;

[0030] The guide plate 40 is mounted on the rotating seat 20 and is movably connected to the die 50;

[0031] An aluminum tube is inserted between the die 50s. When the drive assembly 10 drives the rotating seat 20 to rotate in the forward direction, it drives the die 50 to move inward to compress and deform the aluminum tube; or when the drive assembly 10 drives the rotating seat 20 to rotate in the reverse direction, it drives the die 50 to move outward so that the aluminum tube moves between the die 50s.

[0032] 1) In this utility model, the automatic shrinking device is connected between the pultrusion process and the drawing process. After pultrusion, the aluminum tube is fed into the automatic shrinking device. After the shrinking process of the automatic shrinking device, it is clamped and pulled by the tube drawing mechanism and sent into the drawing device. Specifically, after pultrusion, the aluminum tube is inserted into the shrinking space formed by multiple dies 50. When the drive component 10 drives the rotating seat 20 to rotate in the forward direction, it will drive the die 50 to move towards the center of the directional plate 30 in the directional groove 31 on the directional plate 30 (the directional plate 30 and the pressure plate 81 are stationary), thereby squeezing the aluminum tube and causing the aluminum tube to deform and shrink under pressure.

[0033] 2) In the next stroke of the drive assembly 10, the drive assembly 10 drives the rotating seat 20 to rotate in the opposite direction, which will drive the die 50 to move away from the center of the directional plate 30 in the directional groove 31 on the directional plate 30 (the directional plate 30 and the pressure plate 81 are stationary), thereby causing the die 50 to move away from the aluminum tube. The tube pulling mechanism can grab the part squeezed by the die 50 to pull the aluminum tube to the device.

[0034] 3) In some embodiments, the inner wall of the rotating seat 20 is provided with a plurality of first arc-shaped directional grooves 61, and the guide plate 40 is provided with a plurality of second arc-shaped directional grooves 62. One end of the die 50 extends into the first arc-shaped directional groove 61 and is provided with a guide block 51 extending into the second arc-shaped directional groove 62. When the rotating seat 20 rotates in the forward direction, it will push one end of the die 50 through the first arc-shaped directional groove 61, so that the rotational motion of the rotating seat 20 and the guide plate 40 is converted into the linear motion of the die 50 in the directional groove 31. When the rotating seat 20 rotates in the reverse direction, it will drive the movement of the guide block 51 and the die 50 through the second arc-shaped directional groove 62 on the guide plate 40, so that the rotational motion of the rotating seat 20 and the guide plate 40 is converted into the linear motion of the die 50 in the directional groove 31, and finally realizes the reciprocating motion of the die 50 in the directional groove 31.

[0035] 4) The advantages of this utility model are: the above structure can realize the automatic shrinking of aluminum tubes, which makes it convenient for the tube pulling mechanism to clamp and pull the aluminum tubes. This not only saves labor costs, but also makes the connection between the front and rear of the aluminum tubes in the pulling device smoother, which is conducive to improving the production efficiency of aluminum tubes.

[0036] In a preferred embodiment of the drive assembly 10, the drive assembly 10 includes a motor 11, a reducer 12, a drive gear 13, and a driven gear 14. The output end of the motor 11 is connected to the drive gear 13 through the reducer 12, and the driven gear 14 is connected to the rotating seat 20 and meshes with the drive gear 13. In this configuration, the motor 11 drives the reducer 12 to move, and after being reduced by the reducer 12, it drives the drive gear 13 to rotate. The drive gear 13 drives the rotating seat 20 to rotate through the driven gear 14. By changing the rotation direction of the motor 11, the rotating seat 20 can be driven to move in the forward or reverse direction.

[0037] In some embodiments, the driven gear 14 is integrally formed with the rotating seat 20.

[0038] In some embodiments, the guide disk 40 is connected to the rotating seat 20 via a positioning structure 70 so that the guide disk 40 and the rotating seat 20 rotate synchronously; as a preferred embodiment of the positioning structure 70, the positioning structure 70 is configured as a positioning pin.

[0039] In some embodiments, the directional disk 30 is located on one side of the rotating seat 20 and the guide disk 40 is located on the other side of the rotation. It also includes a pressure plate 81 connected to the directional disk 30 via a detachable structure 80 and pressed onto the guide disk 40. As a preferred embodiment of the detachable structure 80, the detachable structure 80 is configured as a bolted connection structure.

[0040] In some embodiments, an automatic aluminum tube shrinking device further includes a protective cover 90 covering the drive assembly 10, the rotating seat 20, the directional disk 30, the guide disk 40, and a plurality of die-cutting molds 50.
