Description

Technical Field

[0001] The utility model relates to a thickness adjustment mechanism for aluminum rolled materials, belonging to the field of aluminum material production equipment. Background Art

[0002] Aluminum foil is a kind of aluminum rolled material. Aluminum foil mainly refers to its thickness. In the industry, aluminum products with a thickness of less than 0.2mm are usually called aluminum foil. They are usually cut longitudinally at the edges and delivered in rolls.

[0003] At present, the aluminum foil processing process is the aluminum product with the most processing steps, the smallest thickness and the greatest difficulty in the aluminum processing industry. There are currently two commonly used processing routes in the industry, one of which is the ingot hot rolling method;

[0004] Ingot hot rolling method: first, the aluminum melt is cast into a flat ingot, which is generally about 0.5 meters thick. Then the ingot is transported to a special platform by a crane, and the surface of the ingot is treated by a surface smoothing machine. This step can reduce the thickness of the ingot by 3 mm. Then the ingot is placed in a multi-layer thinning process. The aluminum ingot enters between the hot rolling rollers. The thickness will be reduced after being squeezed by the hot rolling rollers. Then the ingot moves back and forth between the hot rolling rollers, and the hot rolling rollers continuously adjust the distance between them, so that the ingot is thinned again and again; finally, a thin aluminum foil is formed.

[0005] Generally, after 12-16 rounds of hot rolling, the spacing between the hot rolling rollers needs to be adjusted 12-16 times, with the distance adjusted the same each time. After these 12-16 times, the flat ingot will change from the original 0.5-meter thickness to 7-centimeter thickness. At this time, the first stage of hot rolling is over. The distance between the hot rolling rollers is reduced each time, and the flat ingot is finally rolled to 0.5-centimeter thickness, completing the second stage of hot rolling. Then, the subsequent rolling and winding operations are carried out. Generally, a 750-kilogram aluminum ingot will be processed into an aluminum foil that is 12.8 kilometers long, 1.5 meters wide, and 0.1 millimeters thick.

[0006] The Chinese utility model patent with application number CN202122895426.6 provides a thickness adjustment device for aluminum foil preparation, but the device is equipped with an electric telescopic rod at the bottom to control the supporting chassis, and can only roll a small amount of aluminum foil of tens of grams, and is not suitable for rolling aluminum foil of hundreds of kilograms. Utility Model Content

[0007] The utility model aims to provide a thickness adjustment mechanism for aluminum rolled material, which can effectively solve the above-mentioned problems.

[0008] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0009] It comprises an upper hot rolling roller and a lower hot rolling roller corresponding to each other, and a hydraulic lifting structure is arranged on the upper hot rolling roller; the hydraulic lifting structure comprises a hydraulic cylinder and fixed blocks arranged on both sides of the lower hot rolling roller, and a limiting rod is arranged on the fixed block; sliders are arranged on both sides of the upper hot rolling roller, a vertical slideway is arranged in the middle of the slider, and the limiting rod is inserted into the slideway; a connecting rod is arranged on the slider, and the connecting rod is connected to the piston end of the hydraulic cylinder.

[0010] Further: the connecting rod includes a vertical rod fixed to the upper end surface of the sliding block and a cross rod arranged between the vertical rods, and the piston end of the hydraulic cylinder is connected to the cross rod.

[0011] Furthermore: a reinforcing rod is arranged between the vertical rod and the cross rod, one end of the reinforcing rod is fixed to the side surface of the vertical rod, and the other end is fixed to the middle part of the lower end surface of the cross rod.

[0012] Furthermore: a support rod is also arranged between the reinforcing rod and the cross rod.

[0013] Further: a circular plate is arranged in the middle of the cross bar.

[0014] Furthermore: the front and rear ends of the vertical rod are provided with limiting grooves, the limiting rod is provided with a limiting strip, and the limiting strip extends into the limiting groove.

[0015] The beneficial effects are:

[0016] This device is a partial improvement on the hot rolling mill. A hydraulic lifting structure is arranged on the upper hot rolling roller. When the device is in use, the upper hot rolling roller and the lower hot rolling roller will rotate, and at the same time drive the aluminum slab to move between the upper hot rolling roller and the lower hot rolling roller. When the hydraulic lifting structure drives the upper hot rolling roller to press down, the thickness of the pressed aluminum slab can be adjusted.

[0017] With this setting, the hot rolling mill can press a kilogram of aluminum ingot into aluminum foil more than ten kilometers long and .mm thick under uninterrupted operation, which is beneficial to industrial production.

[0018] Since the material rolled by this device is relatively hard high-temperature aluminum ingot, the connecting rod has high strength requirements. However, even so, since the shaft diameter of the upper hot rolling roller is too long, generally . meters, the length of the cross bar also needs to be more than . meters. When the middle part of the cross bar is subjected to strong pressure from the hydraulic cylinder, a cross bar of such length will inevitably deform. When the elastic deformation cannot be restored, it will affect the horizontal inclination of the axis of the upper hot rolling roller. Therefore, this application document provides a reinforcing rod, which transmits part of the force through the reinforcing rod to bypass the cross bar and apply it to the vertical rod, thereby increasing the service life of the equipment.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] See also Figure 1-4 This is an embodiment of a thickness adjustment mechanism for aluminum rolled material of the utility model.

[0028] This device is a partial improvement on the hot rolling mill. A hydraulic lifting structure 3 is provided on the upper hot rolling roller 1. When the device is in use, the upper hot rolling roller 1 and the lower hot rolling roller 2 will rotate, and at the same time drive the aluminum slab to move between the upper hot rolling roller 1 and the lower hot rolling roller 2. When the hydraulic lifting structure 3 drives the upper hot rolling roller 1 to press down, the thickness of the pressed aluminum slab can be adjusted.

[0029] This setting allows the hot rolling mill to press a 750-kilogram aluminum ingot into an aluminum foil more than ten kilometers long and 0.1 mm thick while working uninterruptedly, which is beneficial to industrial production.

[0030] The hydraulic lifting structure 3 of the device includes a hydraulic cylinder 31 and fixed blocks 32 arranged on both sides of the lower hot rolling roller 2, and a limiting rod 33 is arranged on the fixed block 32; sliders 34 are arranged on both sides of the upper hot rolling roller 1, and a vertical slideway is arranged in the middle of the slider 34, and the limiting rod 33 is inserted into the slideway; a connecting rod 35 is arranged on the slider 34, and the connecting rod 35 is connected to the piston end of the hydraulic cylinder 31.

[0031] When the hydraulic lifting structure 3 of the device is used, the hydraulic cylinder 31 is started, and the hydraulic cylinder 31 applies thrust to the connecting rod 35. The connecting rod 35 pushes the slider 34 to move downward along the vertical limit rod 33, thereby achieving the purpose of flattening the aluminum ingot, that is, adjusting the thickness.

[0032] The connecting rod 35 includes a vertical rod 351 fixed to the upper end surface of the sliding block 34 and a cross rod 352 arranged between the vertical rods 351 , and the piston end of the hydraulic cylinder 31 is connected to the cross rod 352 .

[0033] Since the thickness of the aluminum foil is very thin, it is necessary to make the upper hot rolling roller 1 be able to be pressed horizontally without deviation when adjusting the thickness; therefore, in order to prevent the upper hot rolling roller 1 from tilting horizontally, only one hydraulic cylinder 31 is used, and then pressed at the middle position of the cross bar 352, so that the force is evenly transmitted to the vertical rod 351, and then the vertical rod 351 is used to drive the slider 34 to move;

[0034] Such an arrangement can ensure the horizontality of the upper hot rolling roller 1, so that the thickness of the rolled aluminum foil is balanced.

[0035] A reinforcing rod 4 is further provided between the vertical rod 351 and the horizontal rod 352 , one end of the reinforcing rod 4 is fixed to the side surface of the vertical rod 351 , and the other end is fixed to the middle part of the lower end surface of the horizontal rod 352 .

[0036] Since the material rolled by the device is a relatively hard high-temperature aluminum ingot, the connecting rod 35 has a high strength requirement. However, even so, since the shaft diameter of the upper hot rolling roller 1 is too long, generally 1.5 meters, the length of the cross bar 352 also needs to be more than 1.5 meters. When the middle part of the cross bar 352 is subjected to a strong pressure from the hydraulic cylinder 31, the cross bar 351 of such a length will inevitably deform. When the elastic deformation cannot be restored, it will affect the horizontal inclination of the axis of the upper hot rolling roller 1.

[0037] Therefore, the present application document provides a reinforcing rod 4, and transmits part of the force through the reinforcing rod 4 to bypass the cross rod 351 and apply it to the vertical rod 351, which can improve the service life of the equipment.

[0038] A support rod 5 is also provided between the reinforcing rod 4 and the cross rod 352 .

[0039] The support rod 5 of the device is used to transmit part of the force exerted on the cross bar 351 to the reinforcing rod 4 through the support rod 5, which can further improve the service life of the equipment.

[0040] A circular plate 6 is provided in the middle of the crossbar 352 .

[0041] The circular plate 6 of the device is used to evenly transmit the force of the hydraulic cylinder 31 to the cross bar 351 .

[0042] Limiting grooves 7 are arranged at the front and rear ends of the vertical rod 351 , and a limiting strip 8 is arranged on the limiting rod 33 , and the limiting strip 8 extends into the limiting groove 7 .

[0043] When the slider 34 slides down along the limit rod 33, the limit strip 8 will also slide along the limit groove 7; and the limit groove 7 and the limit strip 8 add new interference conditions. When there is a gap between the slider 34 and the limit rod 33, it will cause the axis of the upper hot rolling roller 1 to tilt, and the interference between the limit groove 7 and the limit strip 8 can prevent this from happening; this setting is to improve the accuracy of the thickness of the rolled aluminum foil.

[0044] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
