Description
Technical field
The utility model belongs to industrial furnace technology field, in particular, provides a kind of for carrying the overhang roll of round section steel billet.Radical function is conveying round section steel billet, makes the accurate location of steel billet in heating furnace, realize steel billet the outer roller-way of stove and hanging arm roll in stove intermodal transport, accurately a series of material process that automatically takes on such as locate, while, also can be used for carrying square-section steel billet.
Background technology
The method that current employing hanging arm roll carries out feeding is that the most frequently used one of Bar Wire Product walking beam heating furnace takes on stove mode, and steel billet in the orthodox method of stove inner position is: receive rolling line when wanting steel signal, start heating furnace steel billet operation procedure, carry out steel billet and take on stove, stove is taken on by the programming control steel billet set, and after steel billet is parked in desired location, completes a steel billet and take on stove and position fixing process.But the roller head of general conventional overhang roll is tapered cross-section, is suitable for carrying square-section steel billet, if for carrying round section steel billet, easily causing steel billet to drop from overhang roll, causing grave accident.Even if drop, steel billet is also difficult to correct location, often cause step rate normally can not hold up the grave accident of steel billet and steel billet dislocation when being held up (or putting down) by step rate from hanging arm roll, have a strong impact on production, and when processing the problems referred to above, the safety misadventure that easy initiation operating personal is burned, therefore researches and develops a kind of for carrying the overhang roll of round section steel billet to have Great significance.
Summary of the invention
The purpose of this utility model is to provide a kind of for carrying the overhang roll of round section steel billet, solve steel billet the outer roller-way of stove and hanging arm roll in stove intermodal transport, accurately a series of problem automatically taking on material process such as to locate.Device structure is simple, practical, possesses general overhang roll repertoire, the accurate control of conveying to round section steel billet and location can be realized simultaneously, easily be automated control, improve the capacity rating of heating furnace, avoid traditional overhang roll incident field accident when carrying round section steel billet, thus alleviate the labour intensity of production line operation personnel and potential safety hazard caused thus.
For carrying an overhang roll for round section steel billet, comprise roller head 1, main shaft 2, bearing seat 3, coolant inlet pipe 4, base 5, reducing motor 6 and swivel joint 7.Roller head 1 is arranged on one end that main shaft 2 leading portion is positioned at stove; Coolant inlet pipe 4 one end leads directly to one end that main shaft 2 leading portion is positioned at stove, and the other end is connected with swivel joint 7, swivel joint 7 with carry out water lines and be connected, main shaft 2 back segment is connected with swivel joint 7, and swivel joint 7 is connected with water return pipeline; Reducing motor 6 is connected with main shaft 2 back segment, and bearing seat 3 is on base 5 and be connected with main shaft 2 back segment.
Roller head 1 material is heat resisting steel, and roll surface cross section is " V-arrangement ", is fixed on main shaft 2 by flat key and pin.
Main shaft 2 material is heat resisting steel, is divided into two sections, front and back, and centre is cavity structure.
Bearing seat 3 has 2 cover bearings.
Coolant inlet pipe 4 material is solid drawn pipe.
Base 5 is that after Plate Welding, machinework forms.
Reducing motor 6 is overhang roll special retarding motor.
The utility model has the advantage of: this kind of structure design makes cooling area increase, and improves cooling performance; Cooling water expansion tank adopts clean circulating water, can realize closed loop control, be conducive to the recycling of water resource; Adopt water-cooling structure simultaneously, the material of main shaft can be reduced, save device fabrication cost.

Detailed description of the invention
Fig. 1-Fig. 3 is detailed description of the invention of the present utility model.
For carrying the overhang roll of round section steel billet primarily of compositions such as roller head 1, main shaft 2, bearing seat 3, coolant inlet pipe 4, base 5, reducing motor 6, swivel joint 7.This device is arranged on outside stove, and roller head 1 is positioned at stove.At charging end, steel billet is transported in stove by the outer roller-way of stove, after steel billet contacts with overhang roll, will fall in the V-shaped groove of roller head 1 under gravity, and both steel billet line of centers kept overlapping with charging line of centers.When steel billet is close to target location, overhang roll slows down, and when steel billet head arrives target location, overhang roll stops.Now steel billet enters in stove completely, and completes the accurate location in stove.At discharge end, steel billet puts down by step rate, and after steel billet contacts with overhang roll, will fall in the V-shaped groove of roller head 1 under gravity, both steel billet line of centers and discharging line of centers keep overlapping.Overhang roll starts, and is delivered to outside stove by steel billet.
Roller head 1: adopt casting heat resistant steel to form, roll surface cross section is " V-arrangement ", is fixed on by flat key and pin one end that main shaft 2 is positioned at stove;
Main shaft 2: adopt heat resisting steel, be divided into two sections, front and back, carry out respectively forging, machinework, be welded into overall fine limit work afterwards, centre is cavity structure, cools for water flowing;
Bearing seat 3: 2 cover bearings are housed, is fixed on base 5, for the weight of the parts such as bearing roller head 1, main shaft 2, reducing motor 6, and is provided with hole for hoist, is convenient to lifting;
Coolant inlet pipe 4: adopt solid drawn pipe, one end is used flexible pipe by swivel joint 7 and is carried out water lines and be connected, and the other end gos deep into one end that main shaft 2 is positioned at stove, and is welded with back-up block fixed position, carries out water flowing cooling to main shaft 2 working portion in stove;
Base 5: formed by machinework after Plate Welding, for fixed bearing block 3 position, and can finely tune position according to field condition, base 5 is fixed on foundation of civil work, carries whole overhang roll load;
Reducing motor 6: adopt overhang roll special retarding motor, output torque is large, is convenient to install;
Swivel joint 7: connect coolant inlet pipe 4 respectively and come water lines, main shaft 2 and water return pipeline.
