Abstract
A kind of manufacturing method of saddle-shaped forge piece of the present invention belongs to technical field of forging.The technical scheme is that by repeatedly optimizing to have obtained the shape and size of best waste shape, the method being combined by using open die forging, swage forging and die forging, the qualified product of geomery and performance is obtained, realizes the integral forging and forming of parts with complex structures.It is an advantage of the invention that this method is on original forging method basis, before die forging, obtaining designed waste shape by swage forging realizes the integral forging and forming of such parts with complex structures, improve the batch production efficiency of the forging, meanwhile the preparation for the forging provides a kind of new selection approach.
Description
Technical field
A kind of manufacturing method of saddle-shaped forge piece of the present invention belongs to technical field of forging.
Background technology
Such complex-shaped structural forging is difficult by die forging direct forming, usually carries out mould by simplifying forging shape
Then forging is finally embarked on journey by machine cut realization.However die forging combine Cutting Process, forging overlap is more, force energy consumption
Height, subsequent mechanical cutting output is big, not only consumes a large amount of machining periods, but also destroys metal streamline distribution, weakens product machinery
Performance is extremely difficult to the performance requirement of such part.Meanwhile it is unfavorable for current country and industrial emission reduction and low-carbon is manufactured
The realization of target.Thus herein using the method that swage forging is preshaped and die forging is combined, this method realizes labyrinth
The integral forging and forming of part, forging metallic fiber are distributed with shape of product, even tissue, crystal grain refinement, and regular shape can expire
Its special performance requirement of foot.
Invention content
The technical problems to be solved by the invention are：It solves this stress frame and is commonly present Tissue distribution in actual production not
Uniformly, the defects of streamline distribution is unreasonable is caused to scrap.So that the waste shape of forging can be completely filled in follow-up die forging
The cavity of mold realizes the integral forging and forming of such parts with complex structures, improves the batch production efficiency of the forging.
The technical scheme is that：A kind of manufacturing method of saddle-shaped forge piece, the method take following steps：
1) loose tool, cushion block and punch are preheated, its temperature is made to reach 200 DEG C~300 DEG C；
2) cylindrical bar is heated, its temperature is made to reach 1150 DEG C ± 20 DEG C, and keep the temperature 60min ± 10min；
3) bar that step 2 obtains along its axial direction is forged, its height dimension is made to reach 270 ± 5mm；Again along bar
Radial direction forged, its radial dimension is made to reach 210 ± 5mm, obtains blank；
4) blank that step 3 obtains is heated, its temperature is made to reach 1150 DEG C ± 20 DEG C, and keep the temperature 70min ±
10min；
5) loose tool forging molding is carried out to the blank that step 4 obtains.
To loose tool, cushion block and the punch preheating temperature described in step 1 to 300 DEG C.
Cylindrical bar described in step 2 is heated, its temperature is made to reach 1150 DEG C, and keep the temperature 60min.
Blank described in step 4 is heated, its temperature is made to reach 1150 DEG C, and keep the temperature 70min.
The beneficial effects of the invention are as follows：This method realizes the integral forging and forming of parts with complex structures, and forging metal is fine
Dimension is distributed with shape of product, even tissue, crystal grain refinement, regular shape, can be met its special performance requirement, be improved
The batch production efficiency of the forging.And improve the utilization rate of material.
Specific embodiment
A kind of manufacturing method of saddle-shaped forge piece, the method take following steps：
1) loose tool, cushion block and punch are preheated, its temperature is made to reach 200 DEG C~300 DEG C；
2) cylindrical bar is heated, its temperature is made to reach 1150 DEG C ± 20 DEG C, and keep the temperature 60min ± 10min；
3) bar that step 2 obtains along its axial direction is forged, its height dimension is made to reach 270 ± 5mm；Again along bar
Radial direction forged, its radial dimension is made to reach 210 ± 5mm, obtains blank；
4) blank that step 3 obtains is heated, its temperature is made to reach 1150 DEG C ± 20 DEG C, and keep the temperature 70min ±
10min；
5) loose tool forging molding is carried out to the blank that step 4 obtains.
To loose tool, cushion block and the punch preheating temperature described in step 1 to 300 DEG C.
Cylindrical bar described in step 2 is heated, its temperature is made to reach 1150 DEG C, and keep the temperature 60min.
Blank described in step 4 is heated, its temperature is made to reach 1150 DEG C, and keep the temperature 70min.
The present invention is further described in detail below.
Since this stress frame is complicated, projection section is than more typical, and metal is easy to be not fully filled in forging process
The defects of mould, existing Tissue distribution is uneven in actual production, streamline distribution is unreasonable.Thus its main difficulty is famine
The making of shape in process of production, strictly control the technological parameter in above steps.To obtain qualified forging.
Embodiment
My company is the 42CrMo stress frame that certain enterprise provides, and shape and structure is complicated, and difficult point is setting for waste shape
Meter.The waste molding detailed process of shape is as follows：
Fetal membrane mold is made according to the appearance profile of waste shape, waste 2 fire of shape forging is completed；To hammer anvil, clamping apparatus, tire before forging
Mould, cushion block and punch preheating temperature, make its temperature reach 300 DEG C；Cylindrical bar is heated, reaches its temperature
1150 DEG C, and keep the temperature 60min；The first fire forging square billet is carried out on free forging press：By 200 × 518 jumping-ups of φ to H=270 ±
3, compacting one direction of outer diameter is to 210 ± 3 after cleaning anvil face oxide skin, and outer diameter other direction does not have to finishing, and blank allows direct
Into socket form moulding.Obtained blank is heated again, its temperature is made to reach 1150 DEG C, and keep the temperature 70min；The blank that will be obtained
Loose tool forging molding is carried out by particular manufacturing craft on forcing press.
Designed waste shape is obtained by swage forging, solve be commonly present in follow-up actual production Tissue distribution it is uneven,
The defects of streamline distribution is unreasonable is caused to scrap.Realize the integral forging and forming of such parts with complex structures.
