Connecting device for inlet pipe of silking machine and middle guide tube

Abstract

The invention provides a connecting device for an inlet pipe of a silking machine and a middle guide tube. The connecting device includes the inlet pipe of the silking machine and the middle guide tube. The inlet pipe of the silking machine and the middle guide tube are aligned and connected, an orifice of the inlet pipe of the silking machine is a diameter-variable straight pipe, an orifice of the middle guide pipe is a diameter-variable opening, and the large cross-section end of the diameter-variable opening is connected with the straight pipe of the inlet pipe of the silking machine. The diameter of the large cross-section end of the orifice of the middle guide pipe is larger than that of the inlet pipe of the silking machine; the diameter of the small cross-section end of the orificeof the middle guide pipe is same as the diameter of the inlet pipe of the silking machine. The inlet pipe of the silking machine stretches into the middle guide tube for18-22 mm. The device has the advantages that the orifice of the inlet pipe of the silking machine is changed into the straight pipe, the area of the large cross-section end of the diameter-variable opening of the middle guide pipeis enlarged and made to be larger than the sectional area of the inlet pipe of the silking machine, an original section easy to collide is eliminated, steel-heaping phenomena are avoided, the surfacequality of a product is improved, steel-heaping accidents and the rolling-stopping time are reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of high-speed wire rolling, and in particular relates to a connection device between an inlet of a laying machine and an intermediate conduit. Background technique [0002] In the steel wire rolling process, the wire rod needs to be converted from a straight piece to a coil through the laying head after finishing rolling. The feeding roller is sent into the hollow shaft of the laying machine, the motor drives the hollow shaft to rotate through the speed-increasing mechanism, and the hollow shaft drives the spinning disk fixed on it to rotate, so that the wire entering the hollow shaft passes through the rotating spinning tube along the It is extruded in the tangential direction of the spinning disk. However, in the actual operation process, the inlet nozzle of the laying machine is a variable-diameter mouth, and the nozzle of the middle conduit is also a variable-diameter mouth. The area of ​​the large section end o...

Problems solved by technology

However, in the actual operation process, the inlet nozzle of the laying machine is a variable-diameter mouth, and the nozzle of the middle conduit is also a variable-diameter mouth. The area of ​​the large section end of the inlet nozzle of the laying machine is larger than the area of ​​the large section end of the middle conduit nozzle. This design will cause the middle conduit nozzle to hinder the advancement of the rolled piece, resulting in piled steel phenomenon, affecting production quality and progress
