Abstract

The utility model relates to a rolling twisting guide device for a wire stock and bar rolling mill, which comprises a guide tube, a guide tube fixing device, and a rolled piece adjusting mechanism which is assembled at one end of the guide tube, wherein, a cavity of the guide tube is a rotary slide way of a rolled piece, the upper port of the guide tube is matched and connected with a roller, the lower port is an elliptical rolled piece outlet, the rolled piece outlet is corresponding to a rolled piece passage which is formed between two guide rollers of the rolled piece adjusting mechanism, a fixed movement curve of the rolled piece is formed by the rotary slide way of the guide tube and the rolled piece passage, and a desired rotation angle of the rolled piece can be automatically adjusted. Thereby, the quality of the rolled piece and the work efficiency of a rolling mill are enhanced, and simultaneously, the utility model has the advantages of compact structure, convenient installation and debugging, strong reliability, and low accident rate, and the utility model is an ideal rolling twisting guide device for a wire stock and bar rolling mill.

Description

Wire and bar mill scroll torsion guide and guards

The utility model relates to a kind of wire and bar mill scroll torsion guider that is exclusively used in.

At present, roll with the scroll torsion guide and guards in the line rolling bar and mostly adopt, fixedly mount a conduit by the guide and guard box, and connect firmly the structure of a pair of deflector roll at the port of export of its conduit by jaw in the exit of roll.This kind structure in use, to following one milling train inlet an anglec of rotation is accurately arranged from the upper level roll in order to adjust rolled piece, earlier adjust roll spacing between conduit and two deflector rolls repeatedly with operating experience for many years, realize the adjustment angle that rolled piece is required by the technical staff.This kind mode is difficult to grasp exactly the adjustment skill for unfamiliar operating personnel.Because the adjustment of the deflector roll anglec of rotation is improper, cause also happening occasionally of technology accident simultaneously.In addition, reverse the rotation of conduit for convenience, the conduit and the roll shop building of this structure are provided with certain spacing, because the existence of this spacing, when rolled piece nose occurs or plants, very easily cause the person and equipment breakdown.

The purpose of this utility model is to provide a kind of operating procedure simple, can make rolled piece rotate the wire and bar mill scroll torsion guide and guards of location automatically.

The purpose of this utility model is achieved in that a kind of wire and bar mill scroll torsion guide and guards, it comprises conduit and catheter anchoring system and is fitted to the rolled piece guiding mechanism of conduit one end, the cavity of conduit is the rotating slideway of rolled piece, the upper port and the roll of conduit connect, its lower port is ellipticity rolled piece outlet, and the rolled piece path that constitutes between two deflector rolls of described rolled piece outlet and rolled piece guiding mechanism is corresponding.

The dual-side of conduit upper port is provided with an arcuation groove that matches with the groove of roll.The rolled piece guiding mechanism constitutes by deflector roll, jaw, adjustment bolt with the fastening gripper shoe that is connected as a single entity of conduit, the two ends of described gripper shoe are linked to each other with jaw by pivot pin respectively, it is adjusted bolt and is installed in respectively on the jaw of pivot pin both sides, and the front end axle of jaw connects a pair of deflector roll that is parallel to each other.Catheter anchoring system comprises guide and guard box and location securing member, is provided with pipe clamp in the guide and guard box, and the location securing member contacts with pipe clamp.

The technological progress that the utility model is obtained: the rolled piece path that forms between the rotating slideway of conduit cavity and two deflector rolls matches, can adjust the required anglec of rotation of rolled piece automatically, thoroughly changed by adjusting conduit and realized the complex operations process of the required anglec of rotation of rolled piece, conduit and roll shop building adopt to connect airtight and touch simultaneously, can prevent the generation of all kinds of accidents effectively.And this apparatus structure compactness, Installation and Debugging are convenient, and for ease of maintenaince, rolled piece quality and milling train operating efficiency height are a kind of ideal line bar mill scroll torsion guide and guards.

Be that embodiment further describes the utility model below with the accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the right view of Fig. 1.

As shown in Figure 1, 2, rolled piece enters conduit 2 by 1 output of roll, the upper port of conduit 2 is a round mouth, its dual-side has the groove of an arcuation, groove on this groove and the roll 1 matches, 2 on the upper port of its conduit 2 and roll form a coating face, have prevented effectively because a rolled piece end bending or the accident that caused when planting.Conduit 2 is connected with body by a catheter anchoring system, catheter anchoring system comprises guide and guard box 4 and location securing member, be provided with pipe clamp in the guide and guard box, pipe clamp clamping conduit 2, the location securing member is selected a wedge 5 for use, and wedge 5 contact with pipe clamp, wedge 5 unclamp and oblique tightly, can fix and dismounting conduit 2 easily, the installation of conduit 2 and maintenance are very convenient.The fixing of conduit 2 also can adopt alternate manner, as conduit 2 is waited indefinitely with body is affixed.The bottom of conduit 2 is provided with the rolled piece guiding mechanism, described guiding mechanism by deflector roll 6, jaw 7, adjust bolt 8 and form with the conduit 2 fastening gripper shoes that are connected as a single entity 9, two pairs of jaws 7 are linked to each other by the two ends of pivot pin 10 with gripper shoe 9 respectively, the front end axle of jaw 7 connects 6 of a pair of deflector roll that is parallel to each other 6, two deflector rolls and forms a rolled piece path.Adjust bolt 8 and be installed in respectively on the jaw 7 of pivot pin 10 both sides, adjust bolt 8, can adjust the roll spacing of 6 of two deflector rolls easily.The cavity of conduit 2 is a rotating slideway, its lower port is ellipticity rolled piece outlet 3, the center line of relative two roll shop buildings of center line of described ellipticity rolled piece outlet 3 is provided with a torsion angle α, (size of torsion angle α depends primarily on the spacing distance between two milling trains) as shown in Figure 2, rolled piece outlet 3 is corresponding with the rolled piece path of 6 formations of two deflector rolls.I.e. outlet from two rolls 1 enters the mouth through rolled piece passage to the following road milling train of conduit 2 and 6 formations of two deflector rolls, has formed rolled piece twist motion track.Therefore in a single day this guide and guards is installed on the milling train, and its torsion angle α just can not change.But can realize the angle of the required twisting of rolled piece by the roll spacing of adjusting 6 on two guide rails.During work, rolled piece enters conduit 2 from 1 on two rolls with level angle output, and the rolled piece passage through rotating slideway and 6 formations of two deflector rolls of conduit 2 makes rolled piece enter down the road milling train with required windup-degree and enters the mouth.
