Abstract
The utility model provides an abnormal shape fish plate forges mould, includes mould and lower mould, wherein, go up the mould with be equipped with the die cavity between the lower mould, be equipped with insert core in the die cavity, insert core respectively through the drift with go up mould or lower mould fixed connection, go up the mould with be equipped with the hasp of mutually supporting between the lower mould. Adopt the utility model discloses the heterotypic fish plate that makes has higher, more stable comprehensive properties, has reduced manufacturing cost simultaneously, has improved production efficiency, has very important's meaning at railway and die forging technical field.
Description
Technical field
This utility model relates to mechanical field, particularly relates to a kind of various shaped fishplate forging mold.
Background technology
Various shaped fishplate is a kind of critical component of railway rail system, for non-rail shaped steel rail joint area of the same race, its consumption is big,
Specification is many, but its basic structure form and use principle are identical, and simply the different rail types because connecting adjust its overall dimensions, its knot
Configuration formula is as shown in Figure 1.Owing to it uses the particularity of position, being related to the safety of train operation, this product is just carried by this
Go out higher technology requirement, i.e. there is preferable mechanical property (being not less than connected rail), the best shock resistance,
Anti-shearing, wear-resisting etc..
The processing technology of tradition various shaped fishplate is casting, and owing to technique determines, its dense internal organization degree relatively rolls and forges
Poor, and have unavoidably pore, be mingled with, the defect such as shrinkage cavity, and yield rate is relatively low, also has the unfavorable factors such as environmental pollution simultaneously.
Recently, some manufacturers once attempt using common fish platee (equal section) to roll blank, carry out local and forge displacement,
Realizing the manufacture of various shaped fishplate, the problem that this technique is brought is: after secondary forging, due to local forging, the two ends of product
Mechanical performance, tissue disunity, i.e. one section is the mechanical performance of rolling, tissue, and the other end is the mechanical performance of forging, tissue,
There is potential safety hazard；Simultaneously as be secondary forging, increase a heating process, there is also the increasing of resource, the energy and manpower
Add waste.
Therefore, current various shaped fishplate manufacturing technology field, it is badly in need of developing the manufacturing process of a kind of advanced person, its
Produce product and must have higher, stable combination property than existing product, realize reducing production cost simultaneously, improve and produce effect
The purpose of rate, has at railway and swaging technique field and is of great significance, also will bring good economic benefit and society
Benefit.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide various shaped fishplate forging mold, is used for
Solve problems present in prior art.
For achieving the above object and other relevant purposes, this utility model provides a kind of various shaped fishplate forging mold, including upper mold
And lower mold, wherein, between described upper mold and described lower mold, it being provided with die cavity, in described die cavity, be provided with edge core, described edge core leads to respectively
Cross drift and described upper mold or lower mold is fixing is connected, between described upper mold and described lower mold, be provided with the snap close cooperated.
Preferably, in the die cavity of described edge core, draft angle is 4.8-5.3 degree, and the outer draft angle of die cavity is 2.7-3.3 degree.
As it has been described above, various shaped fishplate forging mold of the present utility model, have the advantages that
This various shaped fishplate forging mold, including upper die and lower die, wherein, is provided with die cavity between described upper mold and described lower mold,
Being provided with edge core in described die cavity, described edge core is connected by drift is fixing with described upper mold or lower mold respectively, and described upper mold is with described
The snap close cooperated it is provided with between lower mold.The various shaped fishplate using this utility model to prepare has higher, more stable combining
Close performance, reduce production cost simultaneously, improve production efficiency, at railway and swaging technique field, there is highly important meaning
Justice.
Accompanying drawing explanation
Fig. 1 is shown as this utility model various shaped fishplate schematic diagram.
Fig. 2 is shown as various shaped fishplate forging mold schematic diagram described in the utility model.
In figure, 1 be upper mold, 2 be lower mold, 3 be die cavity, 4 be edge core, 5 be drift, 6 for snap close.

The scope implemented, being altered or modified of its relativeness, changing under technology contents without essence, can when being also considered as this utility model
The category implemented.
Embodiment 1
As in figure 2 it is shown, a kind of various shaped fishplate forging mold of this utility model offer, including upper mold 1 and lower mold 2, wherein,
Being provided with die cavity 3 between described upper mold 1 and described lower mold 2, be provided with edge core 4 in described die cavity 3, described edge core 4 passes through wedge respectively
Ferrum 5 is fixed be connected with described upper mold 1 or lower mold 2, is provided with, between described upper mold 1 and described lower mold 2, the snap close cooperated,
So that more fastening during matched moulds.
In another embodiment, in the die cavity of described edge core 4, draft angle is 4.8-5.3 degree, and the outer draft angle of die cavity is 2.7-3.3
Degree.Bridge portion and overlap storehouse are all made by known technology.
In another embodiment, the most upper and lower mould matrix uses common hot die steel (such as 5CrNiMo), edge core to use high-end heat
Make mould steel (such as H13), to reach to be conveniently replaceable, reduce the purpose of cost.
