Description

Technical Field

[0002] The drawing wheel is one of the important components of the roller equipment for delivering heat pipes in the rolling mill. It is a common drawing wheel on the market. It includes a wheel body 2, an annular V-shaped groove 1 is provided on the outer wall of the wheel body 2, and a through hole 3 for the shaft to pass through is provided on the wheel body 2. The drawing wheel is rotatably arranged on the rolling mill through the axis. The heat pipe is directly placed on several drawing wheels for dragging during transportation. The heat pipe is embedded in the V-shaped groove 1, so that the heat pipe can be well fixed. However, due to the relatively high temperature of the heat pipe, it is also relatively bulky.

[0003] However, after long-term dragging, the bottom of the V-groove 1 is easily worn. After the bottom of the V-groove 1 is worn, the heat pipe cannot be well fixed, and thus needs to be replaced frequently. The traditional drawing wheel is set in one piece, and it needs to be replaced as a whole when replacing, resulting in unnecessary waste. At the same time, the existing drawing wheel cannot adjust and regulate the spacing according to the required size of silicon nitride, which reduces its applicability. Utility Model Content
