Description

Technical Field

[0001] The utility model relates to the technical field of short cold rolling mills, in particular to adjustable cold rolling mill equipment. Background Art

[0002] The cold rolling mill is composed of a frame, rolls, roll bearings, roll adjustment mechanisms, guide devices, rolling stands, etc. The cold rolling mill uses the rolls of the cold rolling mill to roll steel bars and metal plates. During the production process of the cold rolling mill, a feeding platform and a unloading platform are generally arranged at the front and rear ends of the cold rolling mill.

[0003] In the prior art, a Chinese patent with a patent publication number of CN208341371U discloses an adjustable reversible cold rolling mill device, which can stably adjust the second support roll up and down, while extending the service life of the jacking mechanism and reducing the shaking degree and noise during the adjustment process;

[0004] However, the device uses two lifting mechanisms installed on the left and right sides of the bottom of the frame to adjust the lifting and lowering of the bottom support rollers. Although the stability is good, the two lifting mechanisms occupy a large area, which affects the installation of the device. In addition, lifting and lowering through the bottom support rollers will cause the horizontal height of the workpiece to change, making it inconvenient for the workpiece to enter between the two working rollers, affecting normal loading and unloading. Therefore, an adjustable cold rolling mill equipment is designed to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes an adjustable cold rolling mill equipment.

[0006] The technical problem to be solved by the utility model is to provide an adjustable cold rolling mill equipment, which can adjust the height of the upper pressure roller without changing the horizontal height of the workpiece during pressing, and is convenient for normal loading and unloading of the workpiece. It has a small footprint and is easy to install. A single hydraulic cylinder can achieve the adjustment of the horizontal height of the pressure roller, which is more energy-saving and highly practical.

[0007] The technical problem to be solved by the utility model is to provide an adjustable cold rolling mill equipment, including a base, a column, an open groove, a fixed bearing seat, a first rolling roller, a cross plate, a hydraulic cylinder and a lifting plate, the upper surface of the base is fixedly provided with columns on both sides, an open groove is provided in the center of the column, a fixed bearing seat is fixedly provided at the bottom of the open groove, a first rolling roller is rotatably provided between the two fixed bearing seats through a bearing, a cross plate is fixedly provided on the top of the two columns, a hydraulic cylinder is fixedly provided at the center of the bottom surface of the cross plate, a lifting plate is fixedly provided at the output end of the hydraulic cylinder, guide rods are fixedly provided on the left and right bottoms of the lifting plate, a movable bearing seat is fixedly provided at the bottom of the guide rod, a second rolling roller is rotatably provided between the two movable bearing seats through a bearing, a slide groove is provided on both sides of the upper surface of the cross plate, and a bearing component is provided in the slide groove.

[0008] Preferably, the guide rod passes through the open slot, and the movable bearing seat is slidably disposed in the open slot.

[0009] Preferably, track grooves are provided on both sides of the interior of the open groove, and sliding blocks are fixedly provided on the sides of the movable bearing seat.

[0010] Preferably, the slider matches the track groove, and the slider is slidably disposed in the track groove.

[0011] Preferably, the bearing assembly includes a screw rod and a support block, and a screw rod is rotatably provided on one side of the slide groove away from the center of the cross plate through a bearing, and the support block is threadedly connected to the screw rod.

[0012] Preferably, the bottom of the chute is in an inclined shape with a lower level on the side away from the center of the horizontal plate and a higher level on the side close to the center of the horizontal plate.

[0013] Preferably, the bottom surface of the support block is inclined to match the bottom of the slide groove, and the support block is tightly attached to the bottom surface of the slide groove.

[0014] Preferably, the screw rod is arranged parallel to the bottom surface of the slide groove.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] 1. The utility model is provided with a hydraulic cylinder. When it is necessary to adjust the distance between the two rollers, the hydraulic cylinder is opened, so that the hydraulic cylinder drives the lifting plate to rise and fall. The lifting plate rises and falls through the two movable bearing seats of the guide rod, so as to drive the horizontal height of the second roller installed on the movable bearing seat, thereby achieving the effect of adjusting the distance between the first roller and the second roller. A single hydraulic cylinder can adjust the position of the second roller, which is more energy-saving. Adjusting the position of the upper roller will not change the horizontal height of the workpiece, thereby ensuring that the workpiece and the conveyor belt are at the same horizontal height, which is convenient for conveying the workpiece, and the hydraulic cylinder is located at the top of the device to reduce the occupied space.

[0017] 2. The utility model is provided with a slider and a track groove, and the slider on the movable bearing seat slides in the track groove to ensure the stability of the movable bearing seat when it is lifted or lowered.

[0018] 3. The utility model is provided with a support assembly. When the position of the movable bearing seat is adjusted, the screw rod is rotated to drive the support block to move along the slide groove toward the center of the horizontal plate, and the support block slides along the bottom surface of the slide groove, so that the horizontal height of the support block gradually increases until the upper surface of the support block is attached to the bottom surface of the lifting plate, thereby achieving the effect of supporting the support block, and then achieving the effect of supporting the movable bearing seat and the second rolling roller, preventing the pressure at the output end of the hydraulic cylinder from causing damage to the hydraulic cylinder when the hydraulic cylinder is suddenly powered off, thereby ensuring the service life of the hydraulic cylinder.
