Abstract
The invention discloses 5Cr13 deflector roll recess moulding process, it comprises the following steps: to 5Cr13 blank weight jumping-up, pulling, makes forge piece blank reheating forge thoroughly, be compacted, removes blank as-cast structure, shrinkage cavity, rarefaction defect；Blank is carried out vertical material, riveting forging blank edge, rest and reorganization forging stock；90 ° can be used to operate on upper and lower surface for recess in the middle of blank to be pressed into, can the most rotary slotted put in place, in forging actual production process, because operating on when being pushed down into, two ends blank acts in being subject to axially and extends to axial two ends, the resistance of deformation of the little not up to material of centre stress, and keep the most motionless；Operate on and be pushed down into, finished product of resting and reorganizing out；The most stainless intensity is high, and resistance of deformation is big, is any limitation as heating-up temperature again in order to avoid microscopic structure of stainless steel deteriorates, and additionally martensitic stain less steel hardening capacity is good, can certainly quench by air cooling, and the method is simple to operate, it is not necessary to mould, it is ensured that qualification rate.
Description
Technical field
The present invention relates to sinter forging technique, be specifically related to 5Cr13 deflector roll recess moulding process.
Background technology
Flat-die forging is to utilize impulsive force or pressure to make metal all directions Free Transform between upper and lower anvil face, not by any
Limit and obtain a kind of processing method of the forging of required form and size and certain mechanical performance, due to the recruitment of flat-die forging institute
Tool and equipment are simple, and versatility is good, low cost.Compared with cast blank, open die forging eliminates the defect such as shrinkage cavity and porosity, pore,
Blank is made to have higher mechanical property.Forging simple shape, flexible operation.Therefore, it is at heavy-duty machine and strength member
The meaning of particular importance is had in manufacture.
5Cr13 is high carbon martensite rustless steel, and its phosphorus content relatively other rustless steels exceed a lot, and distorsion during quenching is big, geneva
Body phosphorus content is high, therefore can obtain the hardness of more than 60HRC, and 5Cr13 is magnetic, and wearability is splendid, has at a temperature of 700 DEG C
Good toughness and splendid corrosion resistance, be widely used.
Summary of the invention
For solving technical problem described in background technology, the present invention by the following technical solutions: 5Cr13 deflector roll recess molding
Technique, it comprises the following steps:
1) to 5Cr13 blank weight jumping-up, pulling, make forge piece blank reheating forging thoroughly, compacting, remove blank as-cast structure, shrinkage cavity,
Rarefaction defect；
2) blank is carried out vertical material, riveting forging blank edge, rest and reorganization forging stock；
3) 90 ° can be used to operate on upper and lower surface for recess in the middle of blank to be pressed into, owing to 5Cr13 material is the most easily opened
Splitting, can the most rotary slotted put in place, in forging actual production process, because operating on when being pushed down into, two ends blank is by axle
Act on inwards and extend to axial two ends, the resistance of deformation of the little not up to material of centre stress, and keep the most motionless；
4) operate on and be pushed down into, finished product of resting and reorganizing out.
The invention has the beneficial effects as follows: the most stainless intensity is high, resistance of deformation is big, in order to avoid rustless steel
Heating-up temperature is any limitation as by microscopic structure deterioration again, and additionally martensitic stain less steel hardening capacity is good, can certainly quench by air cooling, the party
Method is simple to operate, it is not necessary to mould, it is ensured that qualification rate.
Detailed description of the invention
Embodiment one
5Cr13 deflector roll recess moulding process, it comprises the following steps:
1) to 5Cr13 blank weight jumping-up, pulling, make forge piece blank reheating forging thoroughly, compacting, remove blank as-cast structure, shrinkage cavity,
Rarefaction defect；
2) blank is carried out vertical material, riveting forging blank edge, rest and reorganization forging stock；
3) 90 ° can be used to operate on upper and lower surface for recess in the middle of blank to be pressed into, owing to 5Cr13 material is the most easily opened
Splitting, can the most rotary slotted put in place, in forging actual production process, because operating on when being pushed down into, two ends blank is by axle
Act on inwards and extend to axial two ends, the resistance of deformation of the little not up to material of centre stress, and keep the most motionless；
4) operate on and be pushed down into, finished product of resting and reorganizing out.
For middle recess, 90 ° can be used to operate on upper and lower surface press-in, but the most easily ftracture in view of 5Cr13 material, can
The most rotary slotted put in place (3-5 circle indent puts in place), and in forging actual production process, easily produce end face pars intermedia
Position indent and phenomenon that altitude margin is processed not because operating on when being pushed down into, two ends blank by effect in axially to axle
Extend to two ends, the resistance of deformation of the little not up to material of centre stress, and keep the most motionless.
Claims (1)
1.5Cr13 deflector roll recess moulding process, it is characterised in that it comprises the following steps:
1) to 5Cr13 blank weight jumping-up, pulling, make forge piece blank reheating forge thoroughly, be compacted, remove blank as-cast structure, shrinkage cavity, loosen
Defect；
2) blank is carried out vertical material, riveting forging blank edge, rest and reorganization forging stock；
3) 90 ° can be used to operate on upper and lower surface for recess in the middle of blank to be pressed into, owing to 5Cr13 material the most easily ftractures,
Can the most rotary slotted put in place, in forging actual production process, because operating on when being pushed down into, two ends blank is by axially
Act on and extend to axial two ends, the resistance of deformation of the little not up to material of centre stress, and keep the most motionless；
4) operate on and be pushed down into, finished product of resting and reorganizing out.
