Description
Technical field
The present invention relates to a kind of Forging Technology, particularly the rotating abbreviated system of a kind of forging.
Background technology
The processing of swaging is the processing technology that uses rotary forging press to carry out, and rotary forging press is to forge the metal forming machinery combining with rolling.On rotary forging press, workpiece deformation process is expanded gradually and is completed by local deformation, so resistance of deformation is little, mechanical quality is little, and installed power is low, less energy consumption, and stable working, easily realizes automated production.
The process principle of swaging: the metalwork of casting forge and press by heating, product is processed into the fine and close some strength forging and stamping deformation process that has, swaging is two to hold hammer mould under the arm in turning at a high speed around the longitudinal axis, work periodicity reciprocating motion in sliding formwork.Forging is carried out to the moulding that forges of high-speed high frequency rate.
Existing forging processing process is generally:
Bar heating → first forging molding → finish forging → punching trimming → pre-machined → spinning
The concrete steps of existing technique are as follows:
1, bar heating:
Formulate different material base heating processes according to different size model material base; To be placed in stove and heat through the qualified material base of flaw detection, furnace gas temperature be controlled at 610-625 DEG C, and material base temperature is controlled at 540-550 DEG C, by the heat penetration property coefficient of product standard and type, different-thickness and product, and the heat time of establishment material base;
2, first forging molding:
First determine material base temperature, check whether material base conforms to mould model, determine and errorlessly can carry out forging molding at the beginning of product.After product depanning, estimate product quality, confirm after qualified to carry out next step.
3, finish forging:
Whether, through just forging and insulation, product turns order to finish-forging operation, confirm mould and just cast product and conform to, and carries out finish-forging processing after errorless, needs to estimate product quality after product depanning, confirms after qualified to turn order.
4, punching trimming:
Confirm whether mould conforms to product, confirm errorlessly rear product to be rushed to centre bore and trimming along clout operation.
5, pre-machined:
Upper lower edge to the product after two forging one punchings is overlapping, and pipe is processed.
6, spinning:
By product standard and type, the procedure of spinning machine is programmed, product is fixed on the mould of spinning machine, when product rotates with machine tool chief axis, with spinning roller or catch up with rod to stress on product, make it to produce local plastic deformation.Under the feed motion of spinning roller and the acting in conjunction that rotatablely moves of blank, make local plastic deformation expand to step by step all surfaces of blank, and be close to mould, complete the rotary pressing processing of part, in addition, need test to initial workpiece product physical dimension, product can be produced after reaching technical standard continuously.
But existing technological process is larger for the investment of complete set of equipments, and need complicated mould and auxiliary equipment, automaticity is not high, and production cost is large, is unfavorable for market competition.
In view of this, for solving the problems of the technologies described above, the research and development of the inventor based on association area, and through constantly test and improvement, and then have generation of the present invention.

(2) swage:
Confirming material base and the face of rotary forging press are held under the arm after the hammer pattern number of hammering mould into shape conforms to, material base is swaged; Swage after product depanning, testing product surface quality and size;
(3) punching trimming:
Product is rushed to centre bore and trimming along clout;
(4) spinning:
Product is fixed on the mould of spinning machine, when product rotates with machine tool chief axis, with spinning roller or catch up with rod to stress on product, make product produce local plastic deformation, under the feed motion of spinning roller and the acting in conjunction that rotatablely moves of product, make local plastic deformation expand to step by step all surfaces of product, and be close to mould, complete the rotary pressing processing of part; Need test to the physical dimension of initial workpiece product, product is produced after reaching technical standard continuously.
Beneficial effect of the present invention is:
1, reduce energy resource consumption: different due to the processing mode of swage hydraulic press and common hydraulic press, greatly reduce energy consumption, original process equipment chief engineer leads as 1800KW, and as long as short flow process process equipment is 920KW, reduction energy consumption 51%.
2, improve personnel's utilization rate: due to the raising of automatic control degree of changing into, saved a large amount of human resources, former process flowing line needs 8-10 people, and abbreviated system streamline only needs 4-5 people.
