Description

Technical Field

[0001] The invention relates to the technical field of metal rolling, and in particular to a non-ferrous metal rolling device. Background Art

[0002] Calendering is a technology that extrude heated plastic or metal through a series of rotating horizontal rollers, thereby processing metal or plastic into thin sheet products with different thickness, width and surface finish. Nonferrous metals refer to all metals except iron and iron-based alloys, which are roughly divided into four categories: heavy metals, light metals, precious metals and rare metals. Metals that are usually processed by metal calendering are usually metal coils, which usually need to be rewound again after calendering for subsequent use. The nonferrous metal calendering device in the prior art cannot guarantee the calendering effect because it usually adopts direct calendering without pre-treatment during the calendering process. At the same time, the calendered nonferrous metal coils cannot be automatically rewound after calendering, and the degree of automation is insufficient. Summary of the invention

[0007] Furthermore, the minimum distances between the large pressing roller, the medium pressing roller and the small pressing roller and the upper surface of the carrying plate decrease in sequence.

[0008] Furthermore, an unwinding frame is fixedly mounted on the main frame, a metal roller is rotatably mounted on the unwinding frame, and a metal roll is wound on the metal roller.

[0009] Place the metal roll and metal coil on the unwinding rack, pull the metal coil out from between the feed rollers, and then continue to feed the metal coil until it reaches the large pressure roller, the middle pressure roller, the small pressure roller and passes under the carrier plate. When used for the first time, manually push the metal coil into the winding drum.

[0010] The rotation of the motor drives the motor gear to rotate, which drives the inner gear, bottom shaft, outer gear and outer gear to rotate through the inner transmission belt, and drives the rear inner gear, rear shaft and half-tooth gear to rotate through the outer transmission belt. The rotation of the outer gear drives the short rod gear and the short rod to rotate, thereby driving the long rod to rotate, driving the fixed-point rotating rod and the movable rotating rod to rotate, and the movable rotating rod drives the movable pressure roller to slide along the inclined groove of the rough pressing frame. The heating tube heats the metal coil on the carrying plate, and the metal coil is first rolled by the large pressure roller, the medium pressure roller, the small pressure roller and the carrying plate, and then the metal coil is pressed on the carrying plate by the movable pressure roller and rolled back and forth for preliminary rolling.

[0011] Furthermore, the precision pressing device includes a guide frame fixedly installed on the main frame, a top frame fixedly installed on the guide frame, a lower pressure frame slidably installed on the top frame, a guide column fixedly installed on the lower pressure frame, the guide column and the guide frame are slidably installed, a compression spring is arranged between the lower pressure frame and the top frame, the compression spring is a strong spring, five upper pressure rollers are rotatably installed on the lower pressure frame, five lower pressure rollers are rotatably installed on the main frame, a docking gear is fixedly installed on the lower pressure roller, the five docking gears are connected by a transmission belt, the docking gear close to the half-tooth gear is meshed with the half-tooth gear, a lower docking gear is rotatably installed on the main frame, and the lower docking gear is meshed with the half-tooth gear.

[0012] Furthermore, the distance between the five upper pressing rollers and the lower pressing roller gradually decreases in a direction away from the half-toothed gear.

[0013] The rotation of the half-tooth gear drives the docking gear and the lower pressure roller to rotate intermittently, and the transmission belt drives all the lower pressure rollers to rotate synchronously.

When the metal roll is inserted into the insertion slot, the bracket descends, and the friction wheel forms a friction fit with the winding drum.

[0015] First, the metal coil is manually pushed into the insertion slot on the winding drum. Due to the weight of the metal coil, the bracket descends along the winding frame, the downward pressure spring is compressed, and the winding drum begins to fit with the friction wheel. The half-toothed gear drives the lower docking gear to rotate intermittently, and the lower docking gear drives the friction belt to move, thereby driving the friction wheel to rotate, thereby driving the winding drum to rotate. The rolled metal coil is rolled by the rotation of the winding drum, and the metal coil is intermittently pulled out from the metal roll. At this time, there is no need to manually push out the metal coil. The half-toothed gear drives the docking gear and the lower docking gear to rotate intermittently, so that the metal coil can be fully and initially rolled under the action of the movable pressure roller.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) the initial pressing device provided in the present invention can perform initial rolling on non-ferrous metals, and roll the non-ferrous metals back and forth by means of a movable pressing roller that continuously rolls back and forth, and cooperates with the heating of a heating tube to achieve initial rolling of the non-ferrous metals, thereby improving the rolling effect; (2) the fine pressing device provided in the present invention further rolls the non-ferrous metals after initial rolling by means of a plurality of groups of pressure rollers with variable diameters, and the rolling effect is good.
