Description
Technical field
The invention belongs to the fields of forging, and in particular to a kind of Step Shaft forging mold.
Background technology
Step Shaft is the important part for forming machine.All do the driving member of rotary motion, are required for being mounted on Step Shaft
On, it could realize rotary motion, transmit torque and power.In addition, in certain specific occasions, Step Shaft also has very important
Effect.With the development of industry, the application of Step Shaft will more extensively, and the requirement of precision and efficiency also can be increasingly
It is high.At this stage, the processing method of Step Shaft is mainly open die forging.Open die forging is of less demanding to process equipment used, artificial to grasp
Make arduously, allowance is big, brings inconvenience to postorder processing, is unfavorable for improving production efficiency and product quality, need
A kind of mold of forging Step Shaft.
Utility model content
The purpose of this utility model is to provide a kind of Step Shaft forging mold that is cost-effective, improving efficiency and quality.
The purpose of this utility model is realized in the following manner：A kind of Step Shaft forging mold, including upper die and lower die,
Upper die and lower die correspond to the different-diameter section of Step Shaft respectively, are arranged gasket in lower die, mould in being arranged between upper die and lower die, on
Endoporus is arranged in lower die in mould, middle mould, and the shape of endoporus is corresponding with the shape of Step Shaft, and middle mould is one section or multistage combines.
Stepped hole is arranged in lower die, mould in being arranged on the first rank of stepped hole hole, and gasket, platform is arranged on the second-order hole of stepped hole
The second-order hole internal diameter in rank hole is corresponding with the diameter of the Step Shaft other end.
The utility model has the beneficial effects that：Upper mold, middle mould and lower die combination, internal via shape and Step Shaft shape pair
It answers, saving material more efficient using mold forging ratio open die forging and process；Gasket is set in lower die, it may be convenient to adjust
To adapt to the Step Shaft of different length；Middle mould be divided into one section either multistage can easily be adapted to not by combining or splitting
With the Step Shaft of length, interchangeability is high, reduces die cost.
Description of the drawings
Fig. 1 is the utility model principle schematic diagram.
Fig. 2 is Step Shaft schematic diagram.
Wherein, 1 is upper mold, and 2 be middle mould, and 3 be lower die, and 4 be gasket, and 5 be Step Shaft first segment, and 6 be Step Shaft second segment.
Specific implementation mode
As shown in Figs. 1-2, a kind of Step Shaft forging mold, including upper mold 1, middle mould 2, lower die 3.Step Shaft is divided into two sections,
Step Shaft first segment 5 and Step Shaft second segment 6, setting hole corresponding with Step Shaft first segment 5 in upper mold 1, be arranged on middle mould 2 and
6 corresponding through-hole of Step Shaft second segment；Upper mold 1 is set on middle mould 2；Stepped hole, the uppermost hole of stepped hole are set in lower die 3
Diameter is corresponding with middle mould outer diameter, and mould 2 in being arranged thereon, stepped hole second-order bore dia is corresponding with 6 outer diameter of Step Shaft second segment, rank
Gasket 4 is set on terraced hole second-order hole, and the height of gasket 4 can be adjusted according to the height of Step Shaft second segment 6.
When it is implemented, upper mold 1, middle mould 2, lower die 3 install successively, Step Shaft is mounted on upper mold 1, middle mould 2, lower die 3
In the cavity of formation, the height of adjusting gasket 4 adapts it to the Step Shaft second segment 6 of different height.Step Shaft second segment 6 compares
When long, the middle mould 2 of different height can be replaced or add mould 2 in the preceding paragraph, in addition the gasket 4 of different height, can use one
Mold adapts to the Step Shaft of different length.When Step Shaft has 2 sections or more, each section can be arranged a mold, in addition can
To install the lower die 3 of gasket 4, to adapt to the Step Shaft of different size.The utility model can be used by multistage die assembly
One set of die meets the Step Shaft of plurality of specifications and length, and assembling is easy to use, saves cost, efficient.
Forge the former process route of Step Shaft：200 round steel blankings of φ-intermediate frequency furnace（Heated length about 612mm）Add
Heat-forging（750 hammering, whole pulling forging step）- reheating（Heated length about 1000mm）- forging-blanking sawing
Head-turns sequence delivery）, use the existing process route of the mold forging of the utility model：130 round steel blankings of φ-intermediate frequency furnace
Heating（Heated length about 430mm）- enter pier nose molding-gas cutting-of mold turn sequence delivery.
Using the mold of the utility model, the blank that diameter specifications can be selected small, whole heating is optimized for local end
Heating, can be adapted to the intermediate frequency furnace of more small dimension, shorter heated length improves the efficiency of heating surface, reduces energy consumption；Fire consumption
By two fire, it is optimized for One-time forging molding；Production efficiency greatly improves, and has saved cost；The bright and clean non-scale of face quality, is compared
Open die forging surface, it is ensured that smaller allowance, it is ensured that the higher market competitiveness of Products.
