Abstract
The utility model belongs to mold design technical field, more particularly to five or six gear shift bars forging inclined-plane material extrusion mould.Including upper die and lower die, the die cavity of extrusion forming is useful in upper die and lower die, die cavity includes output axocoel, input axocoel and shift fork chamber, output axocoel, shift fork chamber are sequentially connected with input axocoel, the extrusion mouth of the shift fork chamber is inclined-plane, and the range of tilt angles of its inclined-plane and horizontal plane is 30 °~45 °.The design on this inclined-plane is by reference to the finished size after product later stage mechanical processing, since product pitches body outwardly facing the end in face, the starting point as inclined-plane using on the basis of finished product thickness size, inside axis body direction extension 16.7mm, it is connected with the plane for leaving surplus, a reduction space inclined-plane is formed, cuts down the reserved margin of forging stock to greatest extent, so as to reach the final effect for reducing fork unit volume.
Description
Technical field
The utility model belongs to mold design technical field, more particularly to five or six gear shift bars forging inclined-plane material extrusion mould.
Background technology
In the prior art, five or six gear shift bars belong to long axis products, and axis body diameter is smaller and length is longer, and in major axis
Between the fork body at position be to extend a very long part to outside axis body, from the point of view of unitary construction, belong to the special-shaped product of comparison.Forging
Make in technique, due to the major axis relation of product, usually select the round steel close to axis body diameter to be used as blank, using processing simultaneously
Extrusion billet middle part, be allowed to deformation extension method come reach fork body region shaping.But squeezing by forging equipment
Press, the distance range extended after blank deformation is related with embryo material volume size, and the relatively small blank expanded range of volume is very
Limited, such fork body length often extends less than ideal position, very big obstruction is brought to molding turgor, directly
Influence the qualification rate of product and the production cost of company.
Utility model content
When the technical problem that the utility model solves is existing forging mold extruding, fork body length often extends less than reason
Think position, very big obstruction is brought to molding turgor, directly influence the qualification rate of product and being produced into for company
This.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution:Five or six gear shift bars forge inclined-plane
Material extrusion mould, including upper die and lower die, are useful for the die cavity of extrusion forming in upper die and lower die, die cavity include output axocoel,
Axocoel and shift fork chamber are inputted, output axocoel, shift fork chamber are sequentially connected with input axocoel, and the extrusion mouth of the shift fork chamber is inclined-plane,
The range of tilt angles of its inclined-plane and horizontal plane is 30 °~45 °.
Using above-mentioned technical proposal, in the utility model, after the design on this inclined-plane is machined by reference to the product later stage
Finished size, since product pitch body outwardly facing the end in face, the starting point as inclined-plane using on the basis of finished product thickness size,
Inside axis body direction extension 16.7mm, is connected with the plane for leaving surplus, forms a reduction space inclined-plane, to greatest extent
The reserved margin of forging stock is cut down, so as to reach the final effect for reducing fork unit volume.Set by reference to post-production process
The material reducing inclined-plane of meter out, inclined-plane effectively avoid the situation of no allowance to axis body direction progressively gradual thickness, will not
The effect of post-production is influenced because the surplus position of product is reduced.The structure on inclined-plane is relatively easy, is brought to mould processing
Cheaply, cost of manufacture is saved；Inclined-plane, which can effectively improve, pitches body formed turgor, reduces quality cost.
Further, the chamfer length scope is 3cm~6cm, can so ensure that the fork body later stage after extruding extension adds
The size of work.
Further, the extrusion mouth of the shift fork chamber is two, is equipped with inclined-plane, each surface width scope for 3cm~
6cm, easy to pitch the shaping of body.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is structure front view in embodiment in five or six gear shift bars forging inclined-plane material extrusion mould；
Fig. 2 is shift fork cavity configuration sectional view in embodiment in five or six gear shift bars forging inclined-plane material extrusion mould.
Embodiment
Embodiment 1
As shown in Figure 1, 2：Five or six gear shift bars forge inclined-plane material extrusion mould, including upper die and lower die, in upper die and lower die
The die cavity of extrusion forming is useful for, die cavity includes output axocoel 1, input axocoel 2 and shift fork chamber 3, output axocoel 1, shift fork chamber 3
Sequentially connected with input axocoel 2, it is characterised in that the extrusion mouth of the shift fork chamber 3 is inclined-plane 4, its inclined-plane 4 inclines with horizontal plane
Rake angle scope is 30 °~45 °.4 length range of inclined-plane is 3cm~6cm.The extrusion mouth of the shift fork chamber 3 is two,
Equipped with inclined-plane 4, each surface width scope is 3cm~6cm.
During work, the design on this inclined-plane 4 is by reference to the finished size after product later stage mechanical processing, from product fork body court
The end in export-oriented face starts, the starting point as inclined-plane using on the basis of finished product thickness size, inside axis body direction extension 16.7mm,
It is connected with the plane for leaving surplus, forms a reduction space inclined-plane, cuts down the reserved margin of forging stock to greatest extent, so that
Reach the final effect for reducing fork unit volume.The inclined-plane 4 come out by reference to post-production Process Design, inclined-plane 4 is to axis
Body direction progressively gradual thickness, effectively avoids the situation of no allowance, will not because the surplus position of product is reduced and
Influence the effect of post-production.The structure on inclined-plane 4 is relatively easy, and cheap, saving cost of manufacture is brought to mould processing；Inclined-plane energy
It is effectively improved and pitches body formed turgor, reduces quality cost.4 length range of inclined-plane is 3cm~6cm, so may be used
To ensure the size of the fork body post-production after extruding extension.The extrusion mouth of the shift fork chamber 3 is two, is equipped with inclined-plane 4, often
A 4 width range of inclined-plane is 3cm~6cm, easy to pitch the shaping of body.
Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art
For, on the premise of the utility model structure is not departed from, several modifications and improvements can also be made, these should also be considered as this
The protection domain of utility model, these are all without the effect and practical applicability for influencing the utility model implementation.
