Abstract
The invention discloses a forging process of forgings. The forging process includes the steps of 1, feeding material, and performing cutting to obtain a bar; 2, performing acidifying; 3, coating the surface with lubricant; 4, performing thermal wire drawing, to be specific, selecting two points on the bar, applying certain voltage between the two points to generate great short-circuit current through a voltage difference between the two points, heating the part, between the parts, of the bar until that the part is red at about 1200 DEG C, and drawing the heated bar with a die to obtain a valve blank; 5, performing shot blasting and coating, and after shot blasting, subjecting a graphite coating to anti-oxidation and anti-decarburization; 6, performing forging, controlling the temperature to 1000 to 1200 DEG C, and putting the valve blank in a hollow die for cold forging. The forging process has the advantages that produced products are longer in service life and more stable in quality, the products have no air void inside, production efficiency is improved, and materials are saved.
Description
Technical field:
The present invention relates to forging production and processing technical field, more specifically to a kind of forging and stamping production technology of forging.
Background technology:
Because valve body is often in high pressure conditions, therefore the requirement of valve body to the fatigue resistance of the steel of processing and other physical properties and mechanical performance can be higher, the steel being processed into valve body in prior art are generally the column of strip, these steel obtain this shape by rolling mill practice, its physical property and mechanical performance is changed afterwards again by Technologies for Heating Processing such as annealing, but steel crystalline phase obtained is like this organized stable not, especially there is banded crystalline phase tissue, therefore the mechanical performance of steel each side that obtains of prior art is not high, service life can be shorter, and such unstable product quality, the product appearance machined is coarse, and often there is pore in inside in the product produced.
Summary of the invention:
Object of the present invention is just the forging and stamping production technology providing a kind of forging, the product longer service life that it is produced, and quality is more stable, and interiors of products does not exist pore, and the present invention also improves production and processing efficiency, and it can also play the effect of energy-saving material.
For achieving the above object, the forging and stamping production technology of a kind of forging of the present invention, comprises the steps: (1) blanking, intercepts bar; (2) acidity is carried out; (3) lubricant is coated on surface; (4) hot wire drawing processing is carried out: on bar, choose two points, a voltage is applied between these two points, large short circuit current is formed by the voltage difference between 2 o'clock, steel between 2 o'clock are burnt red in 1200 left and right Celsius, and the steel after this intensification are obtained valve body blank part through mould drawing is shaping; (5) ball blast coating, anti-oxidation, the anti-decarburization of equadag coating after ball blast; (6) forging forming, temperature controls at 1000-1200 DEG C, blank is put into punching mould and carries out cold-forge forming; (7) parting discharging; (8) annealing in process, is heated to 680-720 DEG C, and insulation 2-4 hour, cools to 300-350 DEG C of air cooling of coming out of the stove with the furnace; (9) ball blast, phosphatization, saponification process; (10) ball blast surface treatment.
Preferred as technique scheme, the voltage in described step (4) between bar 2 is powered by Electric Appliance Cabinet, and the voltage simultaneously between these 2 is through transformer pressure-reducing, and Electric Appliance Cabinet is controlled by switch board.
Preferred as technique scheme, temperature-detecting device is equipped with between bar 2 in described step (4), this temperature-detecting device can receive the temperature information of steel between 2, and by the control to temperature between 2 o'clock of the velocity interpolation of the FEEDBACK CONTROL wire of this information.
Preferred as technique scheme, the composition of the lubricant in described step (4) is graphite powder.
Beneficial effect of the present invention is: the product longer service life that the present invention produces, and quality is more stable, and interiors of products does not exist pore, and the present invention also improves production and processing efficiency, and it can also play the effect of energy-saving material.。
Detailed description of the invention:
The following stated is only the preferred embodiment embodying the principle of the invention, does not therefore limit protection scope of the present invention
The embodiment of the forging and stamping production technology of a kind of forging of the present invention, blanking that it comprises the steps: (1), intercepts bar; (2) acidity is carried out; (3) lubricant is coated on surface; (4) hot wire drawing processing is carried out: on bar, choose two points, a voltage is applied between these two points, large short circuit current is formed by the voltage difference between 2 o'clock, steel between 2 o'clock are burnt red in 1200 left and right Celsius, and the steel after this intensification are obtained valve body blank part through mould drawing is shaping; (5) ball blast coating, anti-oxidation, the anti-decarburization of equadag coating after ball blast; (6) forging forming, temperature controls at 1000-1200 DEG C, blank is put into punching mould and carries out cold-forge forming; (7) parting discharging; (8) annealing in process, is heated to 680-720 DEG C, and insulation 2-4 hour, cools to 300-350 DEG C of air cooling of coming out of the stove with the furnace; (9) ball blast, phosphatization, saponification process; (10) ball blast surface treatment.
Voltage in step (4) between bar 2 is powered by Electric Appliance Cabinet, and the voltage simultaneously between these 2 is through transformer pressure-reducing, and Electric Appliance Cabinet is controlled by switch board.
Be equipped with temperature-detecting device between bar 2 in step (4), this temperature-detecting device can receive the temperature information of steel between 2, and by the control to temperature between 2 o'clock of the velocity interpolation of the FEEDBACK CONTROL wire of this information.
The composition of the lubricant in step (4) is graphite powder.
The present invention can make material obtain the product longer service life of better crystalline phase tissue production, and quality is more stable, and interiors of products does not exist pore, and the present invention also improves production and processing efficiency.
