Description

Technical Field

[0001] The utility model relates to the technical field of conveying and cutting, in particular to a cutting machine for producing microchannel aluminum flat tubes. Background Art

[0002] In the production process of aluminum flat tubes, especially in the manufacture of microchannel aluminum flat tubes, cutting is a crucial step.

[0003] The existing microchannel aluminum flat tubes are placed on rollers, and then the aluminum flat tubes are conveyed to the cutting machine end. However, most of the microchannel aluminum flat tubes are prone to deviation during conveying because there is no limiting component, which indirectly affects the uneven cutting of the aluminum flat tubes. During cutting, the aluminum flat tubes will shake, making it difficult to limit and guide the cutting of the flat tubes. Summary of the Utility Model

[0004] In view of this, the utility model provides a cutting machine for producing microchannel aluminum flat tubes, which can prevent the aluminum flat tubes from deviating and can provide fixation when cutting the aluminum flat tubes to prevent shaking during cutting.

[0005] To solve the above technical problems, the utility model provides a cutting machine for producing microchannel aluminum flat tubes, which includes a conveying box. A plurality of rollers are rotatably arranged in the conveying box. Three fixing plates are arranged at the inlet end of the rollers, and a cutting plate is arranged at the outlet end of the rollers. Aluminum flat tubes are arranged on the upper surface of the rollers. Rotating rollers in the anti-deviation mechanism are arranged on the fixing plates, and the rotating rollers are in top contact with both sides of the aluminum flat tubes. Two telescopic columns are arranged on both sides inside the conveying box. Fixing blocks are arranged at the ends of the two telescopic columns, and the fixing blocks are slidably arranged on the upper surface of the cutting plate. A hydraulic telescopic column I is arranged at the top inside the conveying box. A descending fixing block is arranged at the end of the hydraulic telescopic column I, and the descending fixing block is located above the cutting plate. A cutting groove is arranged in the middle of the upper surface of the cutting plate. Two hydraulic telescopic columns II are arranged on the upper surface of the conveying box. Cutting knives are arranged at the ends of the hydraulic telescopic columns II, and the cutting knives correspond to the cutting groove up and down. That is, by driving the anti-deviation mechanism, the rotating rollers are made to top contact both ends of the aluminum flat tubes, so as to prevent the aluminum flat tubes from deviating when being conveyed on the rollers. Then, by driving the telescopic columns, the fixing blocks fix both sides of the aluminum flat tubes. The hydraulic telescopic column I makes the descending fixing block top contact the upper side of the aluminum flat tubes, and then fixes the ends of the aluminum flat tubes. Then, the descent of the hydraulic telescopic column II makes the cutting knives cut the aluminum flat tubes, thus ensuring more stable cutting of the aluminum flat tubes.

[0006] The anti-offset mechanism includes grooves. Grooves are provided on the fixed plates. Sliders are arranged inside the grooves. Mounting seats are arranged on the upper surfaces of the sliders. Rotating rollers are arranged in the mounting seats through pin shafts. That is, the mounting seats provide support for the rotating rollers, so that the rotating rollers provide limit for the aluminum flat tubes during transportation.

[0007] A bidirectional lead screw is arranged in the groove. The bidirectional lead screw penetrates through the two sliders. That is, the bidirectional lead screw can make the sliders move more stably and evenly.

[0008] The anti-offset mechanism includes a single-groove pulley, a double-groove pulley and a synchronous belt. Two single-groove pulleys and a double-groove pulley are arranged at the side end of the conveying box. The two single-groove pulleys and the double-groove pulley are respectively fixed at the ends of the bidirectional lead screw. The double-groove pulley is located at the center of the single-groove pulleys. The double-groove pulley is drivingly arranged with the two single-groove pulleys through the synchronous belt. That is, the rotation of the double-groove pulley can drive the single-groove pulleys to rotate, and thus can drive and transmit the bidirectional lead screw.

[0009] The anti-offset mechanism includes a fixed cover. The fixed cover is arranged at the side end of the conveying box. That is, the fixed cover can protect the internal parts.

[0010] The anti-offset mechanism includes a motor. The motor is arranged at the side end of the fixed cover. The output shaft of the motor is fixedly arranged on the double-groove pulley. That is, the motor can provide drive for the double-groove pulley.

[0011] The bottom of the conveying box is provided with feet. That is, the feet can provide support for the conveying box.

[0012] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0013] 1. Through the operation of the motor, the motor drives the double-groove pulley, then the double-groove pulley drives the synchronous belt, and then the synchronous belt drives the two single-groove pulleys, so that the double-groove pulley and the two single-groove pulleys drive the bidirectional lead screw to rotate. Then the bidirectional lead screw drives the internal sliders, so that the rotating rollers between the mounting seats can adapt to the widths of different aluminum flat tubes, and indirectly can ensure that the aluminum flat tubes are prevented from offset during transportation.

[0014] 2. Through the action of the telescopic column, the fixed block at the end of the telescopic column extends to touch the two sides of the aluminum flat tube. Then, through the lowering of the hydraulic telescopic column 1, the lowering fixed plate touches the top of the aluminum flat tube, ensuring the stability of the aluminum flat tube during cutting. Then, the hydraulic telescopic column 2 drives the cutting knife, and then the aluminum flat tube can be stably cut. Brief Description of the Drawings
