Description

Sheet cooling device

Technical Field

The utility model relates to the field of sheet production and manufacturing, in particular to a sheet cooling device.

Background

The sheet is formed from the surface after being pressed by the corresponding forming machine, but the temperature of the core of the sheet is still high (about 160 ℃) because of the large thickness, i.e. the core of the sheet is not completely solidified, and thus the sheet cooling device is required to cool the sheet. The prior open-close type sheet cooling device comprises a lower frame body with a plurality of lower cooling rollers and an upper frame body with a plurality of upper cooling rollers and supported on the lower frame body in a lifting manner. The sheet cooling device can adjust the height of the upper frame body during working, and enables the upper cooling roller and the lower cooling roller to respectively contact the upper surface and the lower surface of the sheet, thereby being suitable for cooling operation of the sheets with different thicknesses.

The traditional open-close type sheet cooling device generally drives the upper frame body to lift through a hydraulic pump, a plurality of driving cylinders or 2 driving motors. However, the hydraulic pump requires a hydraulic station system to be configured and requires long-term consumption of hydraulic oil and replacement of damaged valves, and equipment costs and maintenance costs are high. In addition, the hydraulic pump and the driving cylinders have the disadvantages of low positioning precision, easy running when fluid fluctuates and the like, and the driving modes of a plurality of driving cylinders or 2 driving motors are difficult to realize complete synchronous action. The problems are easy to cause the upper frame body to incline in the lifting process, and each upper cooling roller cannot smoothly contact the upper surface of the sheet plate, so that the sheet plate is deformed, bent, tilted and turned and the like due to uneven cooling.

The sheet cooling device 100 is further provided with a plurality of lower cooling rollers (not shown) rotatably supported inside the lower frame body 1, each of which defines a first cooling chamber inside and through which cooling water flows. Each lower cooling roller extends along the left-right direction, and the plurality of lower cooling rollers are sequentially arranged along the front-rear direction, namely along the advancing direction of the sheet.
