Abstract

The utility model provides a loop guiding device, belongs to the technical field of a guiding device in a wire/bar rolling line, and is used for solving the defects of poor guidance quality and safety in the prior guiding device. The loop guiding device comprising a loop support, inlet and outlet guide wheels and a guide groove is improved as follows: an auxiliary guide wheel is added on the back of the outlet guide wheel, and has a wheel face at the same level as the groove face of the guide groove; a small flare opening is additionally formed on the back of the auxiliary guide wheel; and a large flare opening is additionally formed at the inlet end of the guide wheel. With the added auxiliary guide wheel, the sliding friction between the guide groove and a rolled workpiece is changed to rolling friction, so that the stable operation of the rolled workpiece is enhanced, the roller-bent workpiece is supported upwards, and the workpiece can smoothly enter the inlet guide of a next rolling mill. The device is applied as the guide device in the wire/bar rolling line.

Description

The kink guider

Technical field

The utility model relates to the guider in the metallurgical line rolling bar production line, belongs to guider technical field in the line rolling bar line.

Background technology

Consult Fig. 2.Kink guider in line, the excellent line rolling line is made up of kink frame 1, inlet guide wheel 2, export orientation wheel 3, gathering sill 4 etc., behind 12 covers of rolled piece, the rolled piece that is certain camber line state contacts with the bottom land sliding friction of gathering sill 4, make gathering sill 4 wearing and tearing fast in the short period of time, influence the stability in the rolled piece 12 guiding processes, cause port of export top steel accident; In addition, the kink frame be exported to the back milling train 10 import lead the position 7 distance segment rolled piece be not straightened condition, also be bending, local contact friction can take place in the clamping plate that position 7 is led in bending rolled piece and import, cause clamping plate to glue the iron sheet phenomenon, slight sticking iron sheet can directly influence surface quality of products, and serious sticking iron sheet will cause entrance point top steel accident; Also have, for convenient back milling train is imported and exported the installation of leading position 7, gathering sill 4 and import are led between the position 7 must leave a segment distance, it is less again that position 7 import bore is led in import, when rolled piece 12 has camber or head misconduct, just can occur feeding the situation that position 7 is led in not import, also cause port of export top steel.Reliable, the poor stability of kink guider guiding of said structure is necessary to improve.

Summary of the invention

The purpose of this utility model provides a kind of kink guider that overcomes the defective of above-mentioned guidance quality, poor stability.

The alleged problem of the utility model realizes with following technical scheme:

A kind of kink guider has kink frame, inlet guide wheel, export orientation wheel and gathering sill in the formation, its improvement is that auxiliary guide wheels is set up in the back of described export orientation wheel, and the wheel face of auxiliary guide wheels and the groove face of gathering sill are contour.

Above-mentioned kink guider, toy trumpet is set up in described auxiliary guide wheels back, and toy trumpet is movably hinged on gathering sill, the import guide and guard of the corresponding auxiliary guide wheels of its typhon mouth entrance point, corresponding next milling train of the toy trumpet mouth port of export.

Above-mentioned kink guider, the entrance point of described inlet guide wheel is set up typhon, the corresponding last milling train outlet guide of its typhon entrance point, the corresponding inlet guide wheel of the toy trumpet port of export.

The utlity model has following characteristics:

1. after auxiliary guide wheels is set up in export orientation wheel back, make between gathering sill and the rolled piece to become rolling friction, can prevent the quick wearing and tearing of gathering sill, strengthen the running stability of rolled piece, and then reduce port of export top steel accident by sliding friction;

2. the auxiliary guide wheel of setting up is to playing the crooked oriented upper support of rolled piece in cover back, make rolled piece become straightened condition, again through the guiding of toy trumpet, can lead the import that rolled piece accurately imports to next milling train stably in the position, can avoid crooked rolled piece and next milling train import to lead the sticking iron sheet phenomenon that friction occurs between a clamping plate, right can prevent because of kink frame and next milling train import lead rolled piece that the hypertelorism of position occurs hello do not advance phenomenon;

3. the toy trumpet of setting up can make the rolled piece that is come out by auxiliary guide wheels enter smoothly in the import guide and guard of next milling train, plays the double action of not only safety but also guiding jointly with auxiliary guide wheels;

4. after inlet guide wheel end is set up typhon, because the import bore of typhon is bigger, can effectively control the direction of motion of standard rolled piece, prevent that the rolled piece of high-speed cruising from running helter-skelter towards back milling train direction when occurring importing fault, make back one personal safety of rolling frame machine operation personnel obtain protection;

The utility model is suitable to be installed and used as the guider in line, the rolling bar production line.

The parts label is respectively in the accompanying drawing: 1-kink frame, 2-inlet guide wheel, 3-export orientation wheel, 4-gathering sill, 5-auxiliary guide wheels, 6-toy trumpet, 7-import guide and guard, 8-typhon, 9-outlet guide, 10-back milling train, 11-preceding milling train, 12-rolled piece.

The specific embodiment

Consult Fig. 1.Main improvement of the present utility model is, auxiliary guide wheels 5 is set up in back at export orientation wheel 3, the same directive wheel for rotating freely with other directive wheel of auxiliary guide wheels 5, the groove face of its wheel face and gathering sill 4 is contour, is advisable with the groove face of a little higher than gathering sill 4.

Still consult Fig. 1.The utility model has also been set up toy trumpet 6 in the back of auxiliary guide wheels 5, toy trumpet 6 is movably hinged on gathering sill 4 by bearing pin, easy to loading and unloading, the import guide and guard 7 of milling train 10 after the auxiliary guide wheels 5 of the corresponding front of its typhon mouth entrance point, the toy trumpet mouth port of export correspondence.

Still consult Fig. 1.The utility model has also been set up typhon 8 at the entrance point of inlet guide wheel 2, and typhon 8 is fixed on the kink frame 1, the outlet guide 9 of milling train 11, the corresponding inlet guide wheel 2 of the toy trumpet mouth port of export before its typhon mouth entrance point correspondence.
