DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0023] Please refer to the drawings in the embodiments of the utility model Figs. 1-3 A roller mill for copper-aluminum composite materials comprises:
[0024] Two portal frames 1, lower roller assemblies 2, upper roller assemblies 3 and two groups of pressing assemblies 4, the upper ends of the two portal frames 1 are provided with connecting beams 10 fixedly connected thereto, the inner vertical walls of the portal frames 1 are provided with symmetrically-arranged die changing slides 11 at the upper ends, and the top surfaces of the two portal frames 1 are provided with reinforcing plates 12 fixedly connected thereto, the lower roller assemblies 2 are fixedly connected to the lower ends of the two portal frames 1 respectively, the upper roller assemblies 3 are movably connected to the upper ends of the two portal frames 1 respectively, the two groups of pressing assemblies 4 are fixedly connected to the reinforcing plates 12, and the pressing assemblies 4 are movably connected with the upper roller assemblies 3; the two portal frames 1 form the outer shell of the whole machine body, and a base with a corresponding height can be welded to the lower ends of the portal frames 1 according to the required height in actual application; considering that the height of the feeding platform cannot be changed, the lower roller assemblies 2 and the upper roller assemblies 3 are used in cooperation to complete the rolling of the metal plate, wherein the lower roller assemblies 2 determine the basic position of the metal plate, and the upper roller assemblies 3 can be adjusted according to the rolling thickness of the metal plate; and considering that the upper roller assemblies 3 have a large weight, it is difficult to directly adjust them by manpower, and the precision cannot be guaranteed, therefore, the pressing assemblies 4 are arranged to adjust the positions of the upper roller assemblies 3.
[0025] Specifically, the lower roller assembly 2 comprises a lower roller 20, a lower roller shaft 21 and two lower roller plates 22, the two lower roller plates 22 are fixedly connected to the lower ends of the two portal frames 1 respectively, the lower roller 20 is located between the two lower roller plates 22, the lower roller 20 is provided with an annular groove 201, the lower roller shaft 21 penetrates through the lower roller 20 and is fixedly connected thereto, and the two ends of the lower roller shaft 21 penetrate through the two lower roller plates 22 and are connected with bearings.
[0026] Specifically, the upper roller assembly 3 comprises an upper roller 30, an upper roller shaft 31, two upper roller plates 32 and two connecting blocks 33, the two upper roller plates 32 are fixedly connected to the upper ends of the two portal frames 1 respectively, the two ends of the upper roller plates 32 are provided with sliding ears 320 fixedly connected thereto, the sliding ears 320 are slidably connected in the die changing slides 11, the upper roller 30 is located between the two upper roller plates 32, the position of the upper roller 30 corresponds to that of the lower roller 20, the upper roller 30 is provided with an annular protrusion 300 matched with the annular groove 201, the upper roller shaft 31 penetrates through the upper roller 30 and is fixedly connected thereto, the two ends of the upper roller shaft 31 penetrate through the two upper roller plates 32 and are connected with bearings, and the two connecting blocks 33 are fixedly connected to the middle positions of the side walls of the two upper roller plates 32 close to the reinforcing plates 12 respectively, the connecting blocks 33 are hollow, and are provided with cylindrical bodies 330 matched with the gaps thereof.
[0027] Considering that the weight of the lower roller 20 and the upper roller 30 is large, the lower roller plate 22 and the upper roller plate 32 are arranged to further fix the lower roller 20 and the upper roller 30. Considering that the upper roller assembly 3 needs to slide along the direction of the mold changing slide 11, sliding ears 320 matched with the mold changing slide 11 are arranged on both sides of the upper roller assembly 3. Considering that the upper roller plate 32 only needs to move in the vertical direction, a connecting block 33 and a cylinder 330 are arranged to connect the cylinder 330 with the external pressing assembly 4, so that the movement direction of the upper roller plate 32 is single. The rolling is completed through the annular groove 201 and the annular protrusion 300, for example, the raw material of the copper-aluminum profile with a certain arc is rolled into a plate shape. By adjusting the distance between the upper roller 30 and the lower roller 20, the gap between the annular protrusion 300 and the annular groove 201 is adjusted, and the thickness of the plate after rolling is controlled.
[0028] Specifically, the pressing assembly 4 includes a pressing base 40, a worm 41, a worm gear 42 and a worm shaft 43. The pressing base 40 is fixedly connected to the reinforcing plate 12, and two pressing bases 40 are respectively located in position corresponding to the two upper roller plates 32. The worm gear 42 is located in the pressing base 40, one end of the worm shaft 43 is connected with the worm gear 42, and the other end is located outside the pressing base 40. One end of the worm 41 passes through the pressing base 40, the reinforcing plate 12, the gantry 1 and the connecting block 33 in sequence and is fixedly connected with the cylinder 330, and the worm 41 is engaged with the worm gear 42. In order to change the vertical position of the sliding plate 32, the worm gear 42 and the worm 41 are used to adjust it. When adjustment is needed, a speed reducer motor matched with the worm shaft 43 is started to drive the rotation of the worm shaft 43, thereby driving the rotation of the worm gear 42. Through the meshing action of the worm gear 42 and the worm 41, the worm 41 is driven to move in the vertical direction, thereby driving the sliding of the upper roller plate 32.
[0029] Specifically, the end of the worm shaft 43 away from the worm gear 42 is provided with a speed reducer motor matched and connected therewith. Considering that the moving distance of the upper roller assembly 3 in the vertical direction is usually small, that is, the movement of the worm 41 needs to be accurately controlled, a speed reducer motor is used to reduce the rotating speed of the worm gear 42, thereby achieving the purpose of controlling the movement of the worm 41.
[0030] Specifically, the lower roller assembly 2 and the upper roller assembly 3 are provided with driving motors matched therewith. It should be noted that considering that the upper roller assembly 3 needs to move in the vertical direction, the motor connected with the upper roller assembly 3 also needs to have the feature of being movable in the vertical direction, and the reverse speed of movement needs to be matched with the pressing assembly 4.
[0031] Specifically, the lower roller 20 and the upper roller 30 are provided with a press wheel positioning assembly 5 away from the driving motor end, the press wheel positioning assembly 5 comprises a press wheel shell 50, a flange plate 51 and a locking ring 52, the press wheel shell 50 is hollow inside, the flange plate 51 is integrally connected to the press wheel shell 50 near the gantry 1 end, the flange plate 51 is fixedly connected to the lower roller plate 22 or the upper roller plate 32, and the lower roller shaft 21 or the upper roller shaft 31 is threadedly connected with the locking ring 52 after penetrating through the lower roller plate 22 or the upper roller plate 32; considering that the lower roller shaft 21 and the upper roller shaft 31 may be deviated during use if not fixed at both ends, the press wheel positioning assembly 5 is arranged at the end of the lower roller 20 and the upper roller 3 away from the motor, and the position of the roller shaft is locked through the press wheel shell 50 and the locking ring 52; it should be noted that, in theory, the end connected with the motor can complete the position positioning of the roller shaft through the motor, but in fact, considering the precision degree of the equipment, the end close to the motor can also be provided with a corresponding press wheel positioning assembly 5 for position positioning.
[0032] Considering that the lower roller 20 and the upper roller 30 have a large weight, if the lower roller shaft 21 and the upper roller shaft 31 simply bear the weight of the roller, the bearing is easy to be worn and needs to be replaced frequently, thereby indirectly increasing the burden of the staff, therefore, it is necessary to reduce the weight borne by the lower roller shaft 21 and the upper roller shaft 31, specifically, the lower roller 20 and the upper roller 30 are provided with a stepped shaft 200 integrally connected away from the driving motor end, the stepped shaft 200 is gap-fitted with the press wheel shell 50 after penetrating through the lower roller plate 22 or the upper roller plate 32, and the stepped shaft 200 is bearing-connected with the lower roller plate 22 or the upper roller plate 32; the stepped shaft 200 integrally connected with the roller is arranged on the roller, the weight of the roller is shared to the lower roller plate 22 and the upper roller plate 32 through the stepped shaft 200, thereby reducing the burden of the roller shaft and avoiding the serious wear of the bearing connected with the roller shaft; it should be noted that, although the stepped shaft 200 is also connected with the lower roller plate 22 or the upper roller plate 32 through a bearing, the bearing has a large volume, and therefore the weight borne by the unit area is small.
[0033] Specifically, the worm 41 is provided with a handle 410 matched therewith; considering that manual adjustment of the worm 41 may be required in some cases, the handle 410 is arranged.
[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
