Abstract
The utility model relates to a die utilizing free forging and hammering rotating shaft forge pieces with steps, which belongs to the technical field of processing of machine tools. The die utilizing free forging and hammering rotating shaft forge pieces with steps is characterized by comprising an upper thrower and a lower thrower, the upper thrower and the lower thrower are provided with die cavities for forging the rotating shaft forge pieces with steps, and cross sections of the die cavities are in the shape of diamond structures. The die has the advantages that the die is simple in manufacture, convenient in use, easy to be repaired after being worn, high in forming die forging rate and quality of forging pieces, short in processing time, low in processing cost, high in production efficiency and long in service life, saves materials and the like.
Description
Technical field
The utility model belongs to the machine tooling technical field, particularly relates to the mould that a kind of flat-die hammer forges band step axle class rotary body forging.
Background technology
At present, a lot of key components such as main shaft, worm screw, gear shaft etc. all are band step axle class rotary body parts in gear machine.This type of part selects the purpose of forging blank to be not only shape and size, and is to improve the original tissue of metal, the mechanical performance of raising metal and physics, chemical property.Therefore how the quality of forging will directly influence the machining accuracy of lathe.This forging adopts open die forging mostly at present, and part adopts loose tooling forging, and the mould structure processing difficulties of loose tooling forging, and the sealing of step axle outside diameter length dimension has limited the scope of application; Enclosed construction stress is concentrated, and is fragile; Also have the loose tool impression directly to contact with high-temperature metal; In cold water, cold and heat succeed each other again constantly; Heat fatigue cracking appears in impression surface easily; Flow of metal produces when defectives such as violent friction impression surface is easy to wear and tear and the hammering pressure is collapsed produce and is difficult for repairing during forging, causes mould to be scrapped; There are technical problems such as forging quality is poor, allowance is big, production efficiency is low.
Summary of the invention
The utility model provides a kind of flat-die hammer to forge the mould of band step axle class rotary body forging for solving the technical problem that exists in the known technology.
The purpose of the utility model provide a kind of have make simple; Easy to use, wearing and tearing back is prone to repair; Loose tooling forging rate and forging quality are high, and material economy, machining period are few, and processing cost is low; Production efficiency is high, and the flat-die hammer of characteristics such as long service life forges the mould of band step axle class rotary body forging.
On flat-die hammer, forge the mould of band step axle class rotary body forging, comprise fall and under fall.Its effect is: will put into to proofread and correct through the forging stock that the open die forging method becomes to be similar to the forging shape to the blank blocking and fall, and not only accomplish correction, the shaping of band step axle class rotary body forging with the mode of pulling and also will accomplish its shaping and guarantee its concentricity and any surface finish.Be characterized in: this mould is that correction, shaping and shaping are integrated; Two step shaft diameter length directions are unrestricted to be open; The flow of metal resistance is easy to for a short time be shaped and as long as forged shaft two adjacent stepped diameters are identical, just can uses secondary a correction to fall shaping, correction and the shaping of accomplishing one type of band step axle class rotary body forging.
The technical scheme that the mould of the utility model flat-die hammer forging band step axle class rotary body forging is taked for the technical problem that exists in the solution known technology is:
A kind of flat-die hammer forges the mould of band step axle class rotary body forging, is characterized in: mould comprises and falls and fall down, on fall and descend fall the impression that step axle class rotary body forging is with in forging, the impression shape of cross section is a diamond structure.
The utility model flat-die hammer forges the mould of band step axle class rotary body forging can also take following technical scheme:
Described flat-die hammer forges the mould of band step axle class rotary body forging, and be characterized in: impression cross section rhombus angle is 100 °-120 °.
Described flat-die hammer forges the mould of band step axle class rotary body forging, is characterized in: 7 °-10 ° of adjacent diameter contact-making surface leaves, and rounding off.
Advantage and the good effect that the utlity model has are:
Flat-die hammer forges the mould of band step axle class rotary body forging owing to adopted the utility model brand-new technology scheme; Compared with prior art; Because this mould is integrated correction, shaping and shaping and two step shaft diameter length directions are unrestricted for open, the flow of metal resistance is easy to be shaped for a short time.So the utility model has not only improved the loose tooling forging rate and the forging quality of forging; And economical with materials, minimizing machined man-hour and reduce cost; The utility model also has simple, the easy to use and advantages such as afterwards being prone to reparation of wearing and tearing of manufacturing in addition.
Description of drawings
Fig. 1 is the mould structure sketch map that flat-die hammer forges band step axle class rotary body forging;
Fig. 2 is the right TV structure sketch map of Fig. 1.
Among the figure: fall 1; 2, fall down; 3, hammer anvil; 4, forging stock.
The specific embodiment
For further understanding technology contents, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
A kind of flat-die hammer forges the mould of band step axle class rotary body forging; Be characterized in: mould comprise fall and under fall; On fall and descend to fall the impression that forges band step axle class rotary body forging, the impression shape of cross section is a diamond structure, the rhombus angle is 100 °-120 °.7 °-10 ° of adjacent diameter contact-making surface leaves, and rounding off.
The concrete combining structure and the forging process thereof of the utility model:
At first will fall 2 down is placed on the hammer anvil 3 reposefully; Then will through the forging stock 4 that the open die forging method becomes the blank blocking to be similar to the forging shape put into down fall in 2 again will on fall 1 and put over against together, thereby on one side fall the 1 continuous mission of rotation blank completion correction, shaping and shaping on one side in the hammering.This mould is that correction, shaping and shaping are integrated; It is unrestricted for open to consult figure one or two step shaft diameter length direction; 7 °-10 ° of adjacent diameter contact-making surface leaves and rounding off; The flow of metal resistance is easy to for a short time be shaped and as long as forged shaft two adjacent stepped diameters are identical, just can uses secondary a correction to fall shaping, correction and the shaping of accomplishing one type of band step axle class rotary body forging like this; Consult figure two and proofread and correct the shaping function impression diameter that falls less than 1～2 millimeter of forging or forging stock diameter dimension, extend efficient and prevent that material folding impression shape of cross section from processing rhombus angle value between 100 °-120 ° for improving for increasing; Also have in the mould use, occur pressing collapse, heat fatigue cracking and wearing and tearing are convenient to repair.This shows that the application of the utility model not only improves the loose tooling forging rate and the forging quality of forging; And economical with materials, minimizing machined man-hour and reduce cost.
