Abstract

The utility model discloses an anti-scratch outlet guide for a rolling mill, which relates to the technical field of metallurgical rolling equipment.

Description

Anti-scratch outlet guide for rolling mill

Technical Field

The utility model relates to the technical field of metallurgical rolling equipment, in particular to an anti-scratch outlet guide for a rolling mill.

Background

A horizontal and vertical alternative continuous rolling mill of a high-speed wire mill comprises a rough rolling unit, a middle rolling unit, a pre-finish rolling unit, a finishing rolling unit and a reducing and sizing unit, wherein corresponding guides are arranged at an inlet and an outlet of each rolling mill as shown in figure 1, the guides are devices which are arranged at the front and the back of a roll pass and help rolled pieces to accurately and stably enter and exit the roll pass according to a set direction and state in the process of rolling profile steel, and each guide is composed of an upper outlet clamp plate 1 and a lower outlet clamp plate 2.

The guide and guard have the following functions in wire production: a rolled piece is correctly guided into a roll pass; ensuring the stable deformation of the rolled piece in the pass and obtaining the required geometric shape and size; smoothly leading out the rolled piece from the pass to prevent the rolled piece from being wound; controlling or forcing the rolled piece to twist or bend and deform and move in a certain direction.

In rolling, the inner wall department of leading defending the export can rub with 3 rubs of red steel, simultaneously because rolling tension's reason, the phenomenon of shake can appear in 3 red steel for the wire rod surface probably can produce the scotch after rolling is accomplished, has influenced the surface quality of finished product wire rod, causes the yields to descend, reduces economic benefits.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an anti-scratch outlet guide for a rolling mill, which comprises an upper outlet clamping plate and a lower outlet clamping plate, wherein the upper end of the upper outlet clamping plate and the lower end of the lower outlet clamping plate are both connected with a horizontal fixing plate, the outer end of the upper outlet clamping plate is provided with two guide wheels which are rotatably connected between the fixing plates, the rotating shafts of the guide wheels are arranged along the vertical direction, the two guide wheels are symmetrically arranged along the width direction of the fixing plates at intervals, the intervals of the two guide wheels correspond to the outlet positions of red steel, the upper end of the upper side fixing plate is also connected with a cooling water pipe, and the water outlet of the cooling water pipe is positioned between the guide wheels and the outer end of the upper outlet clamping plate.

The technical scheme of the utility model is further defined as follows:

further, the fixed plates are symmetrically arranged along the vertical direction.

The anti-scratch outlet guide for the rolling mill is characterized in that the fixing plate is connected with the upper outlet clamping plate and the lower outlet clamping plate through the fixing bolts.

The anti-scratch outlet guide for the rolling mill is characterized in that two fixing bolts are symmetrically arranged along the width direction of the fixing plate.

The anti-scratch outlet guide for the rolling mill is characterized in that the fixing plate is made of steel.

The aforesaid is an anti-friction outlet guide for rolling mill, the upper and lower both ends of guide pulley respectively with upside fixed plate and downside fixed plate inconsistent.

The utility model has the beneficial effects that:

according to the utility model, the red steel is led out from the upper outlet clamping plate and the lower outlet clamping plate in the rolling process, the cooling water in the cooling water pipe simultaneously cools the red steel, when the red steel is led out to a certain degree, the end part of the red steel reaches between the two guide wheels and is mutually abutted against the two guide wheels, and due to the rotating arrangement of the guide wheels, the rolling friction is carried out between the red steel and the guide wheels, so that the scratch of the red steel is greatly reduced, and meanwhile, the two guide wheels play a role in clamping the red steel, so that the swing of the red steel is limited, the finished product quality of wire rods is effectively ensured, and the yield is improved.

Drawings

FIG. 1 is a schematic diagram of a prior art guide;

FIG. 2 is a schematic connection diagram of the present invention;

fig. 3 is a schematic view of the overall structure of the present invention.

Wherein: 1. an upper outlet splint; 2. a lower outlet splint; 3. red steel; 4. a fixing plate; 5. a guide wheel; 6. a cooling water pipe; 7. and (5) fixing the bolt.

Detailed Description

The utility model provides a pair of antifriction export is led and is defended for rolling mill, the structure is as shown in fig. 1 to 3, including last export splint 1 and lower export splint 2, the upper end of going up export splint 1 and the lower extreme of lower export splint 2 all are connected with horizontally fixed plate 4, the material of fixed plate 4 sets up to the steel, two fixed plates 4 set up along vertical direction symmetry, be connected through fixing bolt 7 between fixed plate 4 and last export splint 1 and the lower export splint 2 simultaneously, fixing bolt 7 sets up to two along the width direction symmetry of fixed plate 4.

Go up the outer end of export splint 1 and be provided with two guide pulleys 5 that rotate to connect between fixed plate 4, vertical direction setting is followed to the axis of rotation of guide pulley 5, the upper and lower both ends of guide pulley 5 respectively with upside fixed plate 4 and downside fixed plate 4 inconsistent, two guide pulleys 5 set up along the width direction interval symmetry of fixed plate 4, and the interval of two guide pulleys 5 is corresponding with the exit position of red steel 3, the upper end of upside fixed plate 4 still is connected with condenser tube 6, the delivery port of condenser tube 6 is located between guide pulley 5 and the 1 outer end of last export splint.

Red steel 3 is in rolling in-process, export splint 1 and export down and derive between the splint 2 from last, the cooling water in the condenser tube 6 also cools off red steel 3 simultaneously, after red steel 3 derives to the certain degree, 3 tip arrivals of red steel are between two guide pulleys 5, and contradict each other with two guide pulleys 5, because guide pulley 5's rotation sets up, carry out rolling friction between red steel 3 and the guide pulley 5, thereby the scotch of red steel 3 has significantly reduced, two guide pulleys 5 also play the clamping action to red steel 3 simultaneously, thereby red steel 3's swing has been restricted, the finished product quality of wire rod has effectively been guaranteed, the yields has been improved.

In addition to the above embodiments, the present invention may have other embodiments; all technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
