Abstract

The invention relates to a tube mill, in particular to a feeding device on the front stand of an ASSEL tube mill, which comprises a guide rail part, a feeding part and a driving mechanism, wherein the guide rail part is arranged on the front stand of the ASSEL tube mill; the feeding part can move reciprocally along the guide rail part and is positioned on the outer side of the front stand of the ASSEL tube mill in a horizontal direction; and the driving mechanism can drive the feeding part. The feeding device of the ASSEL tube mill has a simple structure and is convenient for installation and regulation; in a horizontal direction, the feeding device is positioned on the outer side of the front stand of the ASSEL tube mill, which is very favorable for the conveying of tubular billets and prevents tubular billets with a diameter phi of more than 270 millimeters from sliding during conveying; and in a rolling process, the feeding device ensures the smooth biting of the tubular billets and the normal tube rolling and improves production efficiency.

Description

Technical field [0001] The invention relates to a tube rolling mill, in particular to a tube pushing power provided for ASSEL tube rolling mill rolling, and is particularly suitable for large, medium-thick wall ASSEL single-mandrel limiting rolling mills. Background technique [0002] ASSEL tube rolling mill, also known as Assel tube rolling mill, is a three-high cross-rolling tube rolling mill. In the ASSEL limited-movement tube rolling mill for single-mandrel rolling, the tube rolling mill is the main deformation equipment for seamless steel pipe production and one of the key equipment for steel pipe forming. As one of the main auxiliary equipment of the tube rolling mill, the front desk of the tube rolling mill can smoothly receive, thread, feed and ensure the stability of the entire rolling process are several important indicators to measure the front desk of the tube rolling mill. [0003] The front desk of the traditional pipe rolling mill adopts the picking hook to receive ...
