Abstract
The utility model discloses a cold rolled steel extruder, consisting of a rough rolling device, a finish rolling device and an extrusion die; the structure of the rough rolling device is that a rough rolling frame is provided with a pair of rough rollers and a rough roller adjusting mechanism; the structure of the finish rolling device is that a motor drives a pair of finish rollers on the finish rolling frame to rotate through a gearbox and a pair of transmission shafts; the finish rolling frame is provided with a finish roller adjusting mechanism; the central line of the hole type of the rough roller and the central lines of the hole types of the rough roller and the extrusion die are in the same beeline. The cold rolled steel extruder of the utility model has multifunction, not only can cold roll and extrude round steel, but also can cold roll and extrude flat steels and a plurality of section steels; the steel bars products which are made of cold pulling, cold rolling, extrusion and cold processing have good quality; the equipment has the advantages of compact structure, low manufacturing cost, high production efficiency, convenient application maintenance, thus having generalization values.
Description
Technical field
The utility model relates to the cold worked rolling equipment of metal, is specifically related to a kind of cold-rolled steel extruder.
Background technology
At present in the prior art of cold working steel bar, cold rolling steel bar technology and the equal comparative maturity of cold-drawn round steel technology, though cold rolling steel bar equipment and cold-drawn round steel device category are many, cold rolling steel bar equipment is most to be multiple dual structure, and its cold-drawn round steel equipment majority adopts cold drawn step by step mode.Though these equipment are feasible, productivity ratio is lower, and production cost is higher, haves much room for improvement.Simultaneously, do not see cold drawn, cold rolling, extrude equipment in conjunction with cold system steel bar.It is cold drawn, cold rolling, extrude, the cold system steel bar equipment of combination remains to be explored.
Summary of the invention
The purpose of this utility model: a kind of cold-rolled steel extruder is provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of cold-rolled steel extruder, and it is made up of rough rolling device, finish rolling device and extrusion die; The structure of rough rolling device is to be provided with a pair of shaping roll and shaping roll governor motion at pony roughing mill; The structure of its finish rolling device is to pass through gearbox, a pair of power transmission shaft by motor, drives a pair of planishing roll rotation on the finishing stand, and finishing stand is provided with the planishing roll governor motion; The center line of the pass of the center line of the pass of shaping roll and the pass of planishing roll, extrusion die is on same straight line.
Above-mentioned described cold-rolled steel extruder is provided with conduit between finish rolling device and extrusion die.
Above-mentioned described cold-rolled steel extruder, the pass of a pair of planishing roll on the described finishing stand are circle or rectangle, rhombus, regular polygon, and the pass of its described extrusion die also is corresponding circle or rectangle, rhombus, regular polygon.
Above-mentioned described cold-rolled steel extruder is provided with heater before the rough rolling device of cold-rolled steel extruder.Its heater can be electromagnetic heater.
The beneficial effects of the utility model: cold-rolled steel extruder of the present utility model has the following advantages: 1, a tractor serves several purposes, can extrude round steel by cold bundle, and can extrude band steel and some shaped steel by cold bundle again; 2, cold drawn, cold rolling, extrude steel bar good product quality in conjunction with cold system; 3, this compact equipment, the device fabrication cost is low, the productivity ratio height; 4, this equipment productivity height uses easy to maintenancely, has promotional value.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of finish rolling device of the present utility model;
Fig. 3 is the structural representation of rough rolling device of the present utility model;
Fig. 4 is a fundamental diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of cold-rolled steel extruder, it is made up of rough rolling device, finish rolling device and extrusion die 1; The structure of its rough rolling device is to be provided with a pair of shaping roll 42,44 and shaping roll governor motion 45 at pony roughing mill 41; The structure of its finish rolling device is to pass through gearbox 32, a pair of power transmission shaft 33,38 by motor 31, drives a pair of planishing roll 35,37 rotations on the finishing stand 34, and finishing stand 34 is provided with planishing roll governor motion 39; The center line of the pass 36 of the center line of the pass 43 of shaping roll 42,44 and planishing roll 35,37, the pass of extrusion die 1 is on same straight line.Between finish rolling device and extrusion die 1, be provided with conduit 2.The pass 36 of a pair of planishing roll 35,37 on finishing stand 34 is circle or rectangle, rhombus, regular polygon, and the pass of its extrusion die 1 also is corresponding circle or rectangle, rhombus, regular polygon.Bigger as the steel distortion too low or roughing of the operating ambient temperature of cold-rolled steel extruder, can before cold-rolled steel extruder rough rolling device, be provided with heater 5.Cold-rolled steel extruder of the present utility model, by the pass 43 of rolled steel rod 6 elder generations by the shaping roll 42,44 of rough rolling device, next is by the pass 36 of the planishing roll 35,37 of finish rolling device, again by conduit 2, at last by extrusion die 1.The effect of rough rolling device is to change by the line of rolled steel rod 6 footpath and mechanical performance; The effect of finish rolling device is to change directly to be made it moulding by the line of rolled steel rod 6, improves by the mechanical performance of rolled steel rod; The effect of conduit 2 is that the stable shaped steel with shutting out is sent into extrusion die 1; The effect of extrusion die 1 is that the steel bar that will shut out carries out surperficial shaping and surface peening.Cold-rolled steel extruder of the present utility model, as thicker by rolled steel rod 6, can be without conduit 2.Cold-rolled steel extruder of the present utility model, its finish rolling device needs motor drives, and rough rolling device and extrusion die 1 do not need motor drives.Cold-rolled steel extruder of the present utility model, but a tractor serves several purposes by the pass 43 of shaping roll 42,44, the pass 36 of planishing roll 35,37, the pass difference of extrusion die 1, can be extruded round steel by cold bundle, can extrude band steel and some shaped steel by cold bundle again; The combination of cold drawn, cold bundle, extruding technology, its good product quality; This compact equipment, the device fabrication cost is low, the productivity ratio height; This equipment productivity height uses easy to maintenancely, has promotional value.
