Problems solved by technology

[0006] The entire feeding process is driven by the pressure of the hydraulic cylinder to send or return, but pressure fluctuations in the cylinder, fluid shrinkage, piping system changes, and control valves with high inertia systems make it difficult to control the feeding amount of the delivery device. If the feed rate is unstable, it will greatly affect the rolling quality

Abstract

A feeding system of a hot pilger mill comprises a support platform, a conveyer, a feeder and a feeding hydraulic cylinder, wherein the conveyer is erected on the support platform, and the feeding hydraulic cylinder is arranged on the conveyer and drives the conveyer to slide on the support platform. The feeding system of the hot pilger mill is characterized by further comprising an adjustable stopping device and a contact buffer portion, the adjustable stopping device comprises a drive portion and a stopping portion, the stopping portion moves along the sliding direction of the conveyer under the drive action of the drive portion, the contact buffer portion is connected with the conveyer and is positioned in the rear of the stopping portion all the time, and when contacting with the stopping portion, the contact buffer portion sends signals to the feeding hydraulic cylinder to enable the feeding hydraulic cylinder to change internal pressure, so that the conveyer slows down or stops.

Description

technical field [0001] This invention relates to hot pilger mills, and more particularly to feed systems for hot pilger pipe mills. Background technique [0002] The pipe feeding action of the hot pilger pipe mill is completed by its feeding system. The feeding system mainly includes a conveying device, a feeder, and a feeding hydraulic cylinder. The feeder and the hydraulic cylinder are arranged on the conveying device. The movement of the conveying device is driven by the pressure in the hydraulic cylinder. The feeding action is roughly divided into three steps: [0003] 1. Fast feeding: When the blank tube with the mandrel is loaded into the feeder, the conveying device advances quickly with the feeder until the hot tube is sent into the inlet guide groove of the rolling mill, waiting for rolling. [0004] 2. Rolling feeding: when the rolling starts, the conveying device takes the feeder to send the blank tube to the rolling mill at the speed of the work for rolling ...
