(4). keep heating, the cutting knife of the cutting knife moulding frock of single lead screw ex truding briquetting machine is aimed in the axis of round plate cardiac diameter and slow feeding cutting knife, radially cut the grooving of 50-60mm in the outer rim of round plate;
(5). return cutting knife, the moulded head of the cutting knife moulding frock of single lead screw ex truding briquetting machine is aimed in the axis of round plate cardiac diameter and slow feeding moulded head, be fed into till the root degree of depth of grooving, this moment, round plate became the rope sheave workpiece;
(6). return moulded head, the opening installation dish also unloaded the rope sheave workpiece, with rope sheave work-piece cools 5-6 minute;
(7). after the cooling, the axial circumferential welding bearing holder (housing, cover) at the axle center hole place of rope sheave workpiece, then machined rope sheave excircle of workpiece, machining bearing cover the rope sheave finished product.
And the rope sheave finished product after the processing can carry out high-frequency quenching as requested.
And the cooling of rope sheave workpiece can be adopted water-cooled, oil cooling or air cooling mode.
And the structure of described single lead screw ex truding briquetting machine is: this single lead screw ex truding briquetting machine is made of power frock, clamping tooling, cutting knife moulding frock, and its medium power frock is fixed with the power transmission shaft of mounting disc by its other end of fluid motor-driven; Wherein clamping tooling by with the coaxial hydraulic piston cylinder of the power transmission shaft of power frock as power, the other end of its piston rod is hinged with a driven shaft, but the end of this driven shaft be fixed with one with the mounting disc equal and opposite in direction of power frock and symmetry and the mounting disc of clamping round plate therebetween; Wherein cutting knife moulding frock is driven by hydraulic piston cylinder, its piston rod end installs a head box, be connected with the bracing frame that is separately installed with cutting knife and moulded head by the dovetail slide block on this head box, this dovetail slide block is realized the lateral displacement of dovetail slide block by being installed in lateral displacement oil cylinder on the head box, and cardiac diameter all overlaps with cardiac diameter in the axis of round plate in the axis of cutting knife and moulded head.
And cutting knife and moulded head are driven rotation.
Description of drawings
Fig. 1 is a single lead screw ex truding briquetting machine general structure vertical view of the present invention (having omitted flame gun).
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
This rope wheel pressed forming process is made of following steps:
(1) steel plate cutting being become diameter is that ￠ 500-800mm, thickness are the round plate of 16-20mm, and diameter and thickness come fixed according to demand, and this steel plate is generally selected materials such as 45# steel, 16Mn, 35CrMo for use;
(2) round plate after the blanking is processed axle center hole on lathe, promptly at the axle center hole that is used to install bearing holder (housing, cover) of the coaxial ￠ of the processing 150-220mm in the axle center of this round plate.
(3) will process between coaxial two mounting discs that are installed in rope wheel pressed forming machine of round plate behind the axle center hole and clamp, start the hydraulic motor of single lead screw ex truding briquetting machine and to be this motor make mounting disc drive the round plate rotation with the rotating speed of 50-60r/min.After the rotation, the flame gun that starts the single lead screw ex truding briquetting machine next door is to the heating of the edge of round plate, and heating-up temperature makes the edge of round plate burn till red ring between 1000-1100 ℃;
(4). keep flame gun heating, the cutting knife of the cutting knife moulding frock of single lead screw ex truding briquetting machine is aimed in the axis of round plate cardiac diameter and, radially cut the grooving of 50-60mm at the outer rim center of round plate by the slow feeding cutting knife of hydraulic piston cylinder;
(5). return cutting knife, start horizontal oil cylinder, lateral displacement by the dovetail slide block is aimed at the moulded head of the cutting knife moulding frock of single lead screw ex truding briquetting machine in the axis of round plate cardiac diameter and slow feeding moulded head, is fed into till the root degree of depth of grooving, and this moment, round plate became the rope sheave workpiece;
(6). return moulded head, the opening installation dish also unloads the rope sheave workpiece, and the rope sheave workpiece was cooled off 5-6 minute with water-cooled, oil cooling or air cooling mode as required, generally adopts water-cooling pattern;
(7). after the cooling, the axial circumferential welding bearing holder (housing, cover) at the axle center hole place of rope sheave workpiece, machined rope sheave excircle of workpiece then, reprocessing bearing holder (housing, cover) cylindrical or end face, the rope sheave finished product.In order to improve the quality of rope sheave, also can carry out high-frequency quenching to the rope sheave finished product of processing as requested.
Below in conjunction with accompanying drawing, the structure (this single lead screw ex truding briquetting machine is applied for a patent in addition) of narration single lead screw ex truding briquetting machine.
This single lead screw ex truding briquetting machine is made of power frock, clamping tooling, cutting knife moulding frock three parts.Be respectively: power frock, clamping tooling and cutting knife moulding frock.
