Description

Technical Field

[0001] The utility model relates to the technical field of calendering, in particular to a ferrous metal calendering machine. Background Art

[0002] Calendering is a processing method that uses the strong shear force between rollers to extrude and stretch the material, eventually making it into a thin sheet product with width and thickness. Ferrous metals are the general industrial name for iron, chromium and manganese; they also include alloys of these three metals, especially alloy steel and steel.

[0003] Compared with non-ferrous metals, ferrous metals have poorer ductility. Therefore, greater pressure is required when calendering ferrous metals. As a result, the calendering roller will deform during the calendering process, usually with the center of the calendering roller being lifted up. As a result, the middle part of the finished product is thicker and the sides are thinner, which ultimately results in a low yield of ferrous metal calendering. Utility Model Content

The fixed roller structure and the movable roller structure can form a relatively rotating extrusion gap, and when the ferrous metal sheet passes between the fixed roller structure and the movable roller structure, the ferrous metal sheet can be rolled.

[0026] Specifically, the two sliding structures include: a sliding track 6, a slider 7, a telescopic rod 8, a constant pressure spring 9 and a pressure sensor 10; the sliding track 6 is installed on the upper wall of the fixed roller support plate 2, the slider 7 is movably installed inside the sliding track 6, the pressure sensor 10 is installed on the inner upper wall of the sliding track 6, the telescopic rod 8 is installed between the slider 7 and the pressure sensor 10, the constant pressure spring 9 is installed between the slider 7 and the pressure sensor 10, and the constant pressure spring 9 is sleeved on the outside of the telescopic rod 8, and an alarm light 19 is installed on the upper wall of the sliding track 6. The sliding structure can enable the movable roller structure to realize the self-protection function. When the calendering pressure exceeds the maximum force that the movable roller structure can withstand, the sliding structure can help the movable roller structure to move, and at the same time, an alarm is issued to remind the operator.

[0027] Specifically, the power structure includes: a power motor 13, a driving wheel 14 and a transmission belt 15; the power motor 13 is installed on the upper wall of the base plate 1, the driving wheel 14 is installed on the driving end of the power motor 13, and the transmission belt 15 is sleeved on the outside of the driving wheel 14 and the driven wheel 4. The power structure can drive the fixed roller structure to rotate, and can enable the fixed roller structure to perform calendering work.

[0028] Specifically, the winding structure includes: a winding frame 16, a winding roller 17 and a winding motor 18; the winding frame 16 is installed on the upper wall of the base plate 1, the winding roller 17 is installed inside the winding frame 16, the winding motor 18 is installed on the side wall of the winding frame 16, and the driving end of the winding motor 18 is connected to the winding roller 17. The winding structure can wind up the calendered ferrous metal sheet. By changing the speed, it can ensure that the ferrous metal sheet can be rolled up smoothly to avoid damage caused by accumulation or pulling of the ferrous metal sheet.

[0029] Working principle: When using the utility model, first connect the external AC power supply to the utility model to provide energy for the electrical appliances in the utility model, then the operator places the ferrous metal raw material to be rolled inside the raw material rack 20, and manually inserts the ferrous metal sheet between the fixed roller 5 and the movable roller 12, and finally fixes it on the outside of the winding roller 17, and then starts the utility model to work, the power motor 13 drives the rotating driving wheel 14 to rotate, and drives the driven wheel 4 to rotate through the transmission belt 15, and the rotation of the driven wheel 4 drives the fixed roller 5 to rotate. At this time, the relative extrusion of the fixed roller 5 and the movable roller 12 completes the rolling work of the ferrous metal sheet, and finally the winding roller driven by the winding motor 18 17 is wound up, and the winding motor 18 adopts a servo motor with adjustable speed. Through the preset speed change, the outermost speed limit of the winding roller 17 can be kept consistent with the linear speed of the fixed roller 5, thereby ensuring that the ferrous metal sheet will not be damaged by the excessive winding speed, and when the ferrous metal sheet material is too thick, the movable roller 12 will drive the slider 7 to move upward on the sliding track 6. At this time, the fixed pressure spring 9 and the telescopic rod 8 are contracted, and the pressure on the pressure sensor 10 increases, and an alarm is issued through the alarm light 19, wherein the threshold value of the deformation force of the fixed pressure spring 9 is the same as the pressure threshold value for the pressure sensor 10 to issue an alarm, and this force threshold is slightly smaller than the pressure at which the movable roller 12 will be deformed, so that the movable roller 12 can be protected.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
