Technical Field

The invention relates to the field of hollow rolled tube rolling, in particular to a core rod supporting mechanism and a cast blank loading device.

Background

In the nonferrous metal copper processing industry, a hollow rolled tube is rolled by passing a cast blank through a core rod, and the core rod is rotated with rotation of the cast blank during the rolling. Because the length of the core rod is longer than that of the cast blank, a plurality of supporting mechanisms are arranged on the conveying roller path and used for supporting the core rod so as to ensure the straightness of the core rod, and the hollow rolled pipe meeting the requirements can be produced, so that the core rod supporting mechanism plays an important role in the rolling process.

In the existing rolling process, a plurality of supporting mechanisms are required to be sequentially arranged on a conveying roller path for supporting the core rod, but because the supporting mechanisms adopted can only be laterally inverted in a single direction, the supporting mechanisms which can be laterally inverted forwards or backwards respectively need to be sequentially arranged at intervals to realize the support of the core rod. For example, if a first support mechanism is tipped forward, a second support mechanism may need to be tipped rearward and all support mechanisms may need to be lowered prior to casting the blank in order to cast the blank. In the process of pushing and rolling the blank by the feeding trolley, when the feeding trolley passes through the lateral support mechanism, the support mechanism is adjusted by the adjusting lever to support the core rod, so that the core rod and the blank can rotate synchronously for rolling. In the subsequent casting material feeding, a plurality of supporting mechanisms are still required to be knocked down to push the casting material, but the casting blank continuously pushed forward can only be knocked down by the core rod supporting mechanism which is knocked down forwards, but cannot be knocked down by the core rod supporting mechanism which is knocked down backwards, so that the feeding can be continued after the supporting mechanism which is knocked down backwards is knocked down when the feeding trolley is required to return. Therefore, the core rod supporting mechanism used at the present stage provides a barrier for the continuous material strip of the cast blank, the subsequent material of the cast blank can be continued after the supporting mechanism which is inclined to the rear side is knocked down when the feeding trolley returns, the connection time of the material between the previous cast blank and the next cast blank is long, the material loading speed is slow, and the rolling efficiency of the hollow rolled pipe is influenced.
