Description

Technical Field

[0001] The utility model relates to an edge auxiliary heating device. Background Art

[0002] The raw materials of aluminum strip (Aluminum strip / Aluminum strip) are pure aluminum or aluminum alloy cast-rolled aluminum coils, hot-rolled aluminum coils, which are rolled into thin aluminum coils of different thicknesses and widths by cold rolling mills. After the aluminum strip is processed, it needs to be cooled to reduce its deformation, and then it is transported to the drum through multiple sets of rollers to collect the aluminum strip for easy transportation.

[0003] When a cold rolling mill rolls aluminum strips, its rollers will heat up. Since the heat dissipation in the middle of the rollers is slow and inconsistent with the heat dissipation rate at both ends, the coils will easily have abnormal plate shapes such as tight edges during the production process. Some products even tear and break at the edges due to edge cracks on the rear end of rolling. There is an urgent need for a device to reduce the temperature gradient between the edge and center areas of the rollers. Utility Model Content

[0007] Furthermore, a slide groove for the roller to slide into is recessed at the upper end of the slide rail, and both ends of the slide groove are blocked and limited by blocks fixed to the slide rail.

[0008] Furthermore, two groups of support frames are symmetrically arranged at the lower end of the transverse moving platform, and two groups of slide rails are arranged corresponding to each group of heating components.

[0010] Furthermore, a plurality of harness guide blocks are arranged at intervals on the longitudinal side end surface of the mounting frame along its transverse extension direction, and guide holes are vertically penetrated through the harness guide blocks.

[0011] Furthermore, a vertical mounting plate is fixedly connected to the upper end of the servo motor at the end of the transverse moving platform, and a distance sensor is embedded in the mounting plate, and the sensing side of the distance sensor faces the heater.
