Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to an aluminum sheet rolling transmission mechanism. Background Art

[0002] Due to the characteristics of aluminum such as light weight, high strength, weather resistance, good formability and recyclability, aluminum is widely used in the automotive industry, home appliances and construction industry. In these fields, there is a great demand for aluminum with complex shapes and high strength, especially aluminum plates rolled into rectangular plates from aluminum ingots are widely used in the field of home appliances, such as evaporators. Aluminum plates are divided into thin plates below 10 mm and medium and thick plates above 10 mm according to their thickness. Aluminum plates need to undergo aging heat treatment after extrusion molding to obtain better mechanical properties.

[0003] After searching, it was found that the publication number is CN114277240B, and the name is an aluminum sheet rolling conveying mechanism and a heating furnace using the mechanism. The application proposes that during the conveying and rolling heat treatment process of aluminum sheets, the traditional method is usually to use rollers for conveying, and workers place the aluminum sheets flat on the rollers one by one. Since the surface of the aluminum sheet is in direct contact with the rollers, the roller speed is not synchronized with the running speed of the aluminum sheet, and friction is generated between the two, which can easily scratch the surface of the aluminum sheet and affect the product quality. In addition, the width of the aluminum sheet is usually 200 to 600 mm. For a heating furnace with a length of 10 m, only 5 aluminum sheets can be conveyed at a time. The flat conveying of the aluminum sheet occupies a large space, has low work efficiency, and is labor-intensive. The labor intensity is high, especially for thin plates with a thickness of less than 10mm. Due to their small mass and light weight, the aging heating is prone to uneven heating and deformation, which affects the quality of the aluminum plate. By arranging a support frame and a conveying roller above the base, a rotating shaft is installed at equal intervals in the middle of the support frame. The rolling of the rotating shaft can directly roll and convey the aluminum plate with a certain thickness and length, and a rotating groove is opened in the middle of the rotating shaft and a clamping block is installed. The rotating shaft and the clamping block are connected by a spring, which is convenient for driving the clamping block to rotate synchronously during the rotation of the rotating shaft, thereby driving the aluminum plate clamped in the middle of the clamping block to transmit downward, ensuring the stability of the aluminum plate during the transmission process, and the clamping block The blocks are symmetrically installed in groups inside the rotating groove, and the clamping blocks on the upper and lower sides only contact the upper and lower sides of the aluminum plate to avoid scratching and damage to the surface of the aluminum plate, fix the aluminum plate, and prevent the aluminum plate from tilting and falling during the transmission process. At the same time, by separating the support frame into a first side plate, a second side plate and a third side plate, and connecting the first side plate, the second side plate and the third side plate through a first connecting frame, a second connecting frame and a bracket, it is convenient to adjust the interval height between the first side plate, the second side plate and the third side plate evenly and synchronously during the telescopic deformation of the bracket, and it is convenient to adjust the height of the aluminum plate transmitted by the support frame, so as to adapt to the transmission and processing of aluminum plates of different heights, increase the installation The transmission of the device is stable and diverse. In addition, by stacking three rows of rotating shafts at equal intervals on the support frame and connecting them through gears, belts and chains, it is convenient to rotate the rotating shafts connected inside the first side panel and the third side panel, and the aluminum plates on the upper and lower sides of the rotating shaft on the second side panel are connected to drive the aluminum plates on the upper and lower sides of the second side panel to be transmitted to both sides, thereby improving the transmission efficiency of the aluminum plates and facilitating fast and efficient processing of the device. However, this application uses clamps to clamp the aluminum sheets. The width of the aluminum sheets varies and may not be universal. In addition, its structure is relatively complicated and the spacing needs to be frequently adjusted to match the use of aluminum sheets of different thicknesses. It is relatively troublesome and can be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
