Description

Technical Field

[0001] The utility model relates to the technical field of plate rolling machines, in particular to a plate rolling machine for rolling cold-rolled steel plates. Background Art

[0002] Cold-rolled steel sheet is an important steel product with the advantages of precise thickness, smooth surface and excellent mechanical properties. It is widely used in automobile manufacturing, electrical products, construction and home appliances.

[0003] The plate rolling machine used for rolling cold-rolled steel plates is a mechanical equipment specially used for rolling and forming cold-rolled steel plates. According to its structure and function, it can be divided into several types, such as mechanical plate rolling machine, hydraulic plate rolling machine and CNC plate rolling machine.

[0004] The plate rolling machine is mainly composed of upper rollers, lower rollers, side rollers and transmission system. When working, the cold-rolled steel plate is placed between the upper and lower rollers. Through the drive of the rollers and the action of roller pressure, the steel plate is gradually curled to form the desired shape.

[0005] After the existing plate rolling machine is finished rolling, the fixing piece at one end of the upper roller needs to be removed during the unloading process of the ring-shaped steel plate, and then the formed steel plate is pushed out by the pushing unit. This method can quickly unload the formed steel plate, but the steel coil is heavy. During the pushing process, the upper part of the steel coil has no support, which can easily cause the steel coil to deform under its own weight and the shaking caused by pushing, affecting subsequent processing. Therefore, those skilled in the art provide a plate rolling machine for rolling cold-rolled steel plates to solve the problems raised in the above background technology. Utility Model Content

[0011] Preferably, the bottom end of the second hydraulic rod is fixedly mounted on the machine tool, the slider is slidably engaged with the slide groove, and the motor is fixedly mounted on the slider. Therefore, the second hydraulic rod is contracted to adjust the height of the slider and the support tube to support the top inner wall of the annular steel plate, thereby achieving the effect of supporting and preventing the annular steel plate from deforming.

[0012] Preferably, both ends of the push plate pass through the limiting grooves and are connected to the threaded sleeve, and the motor drives the screw to rotate, and the rotation of the screw drives the threaded sleeve and the push plate to move, thereby pushing the formed annular steel plate toward the side where the fixing part is tilted, so that the formed steel plate is pushed out of the machine tool.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a plate rolling machine for rolling cold-rolled steel plates, which has the following beneficial effects:

[0015] Through the design, after the machine tool is running, the upper roller and the lower roller roll the incoming cold-rolled steel plate. Before the steel plate is formed, the height of the support cylinder is adjusted according to the inner diameter of the annular steel plate to be formed, and the height of the support cylinder is in contact with the top inner wall of the annular steel plate under the control and adjustment of the second hydraulic rod, thereby supporting the annular steel plate. When the steel plate is formed, the motor drives the screw to rotate, and the rotation of the screw drives the threaded sleeve and the push plate to move, thereby pushing the formed annular steel plate toward the side where the fixed part is tilted, so that the formed steel plate is pushed out of the machine tool. This mechanism can support the top of the formed annular steel plate when the equipment is unloading, to avoid the problem that the steel coil is heavy and easily deformed under its own weight and the shaking caused by pushing when it is pushed out, resulting in difficulties in subsequent processing.
