Description
Technical field
This utility model relates to Design of Dies technical field, particularly relates to a kind of one or two grades of shift fork finish-forging dies.
Background technology
Some auxiliary components commonly used in the vehicles and plant equipment, the many less rules of its shape, shift fork is exactly one common in this kind of part, the traditional diamond-making technique of these parts mostly is casting, working (machining) efficiency and the precision of this processing method are the lowest, and easily cause the damage etc. of other strength member in the vehicles and plant equipment, these parts can also use forging method to process, forging die in the past is unreasonable due to structure design, mould strength is low, precision is low, affect the service life of driving parts, cost is high, therefore a kind of lower mold convenient fixing of design, reliably, safety is good, part finish-forging forming efficiency is high, one or two grades of shift fork finish-forging dies that the finish-forging precision of part is high seem the most necessary.
Utility model content
The purpose of this utility model is contemplated to overcome prior art to process shift fork complex process, and efficiency is low, the defect that precision is low, devising a kind of one or two grades of shift fork finish-forging dies, lower mold convenient fixing, reliable, safety is good, part finish-forging forming efficiency is high, and the finish-forging precision of part is high.
Solve the technical problem that required by this utility model and can be achieved through the following technical solutions:
A kind of one or two grades of shift fork finish-forging dies, including upper die and lower die, the matrix of described upper mold and described lower mold is a cuboid, it is characterized in that: also include that drag groove, core rod, cylindrical hole, upper model are convex, described drag groove is positioned at the upper surface centre position of described lower mold, symmetrical front and back, the convex lower surface being positioned at described upper mold of described upper model, described upper model is convex is also symmetrical front and back, and the left back and the right front that are positioned at described lower mold are machined with described cylindrical hole.
Described upper mold becomes 1 × 45 ° of root face with the equal chamfering of all sharp edges of described lower mold.
It is provided with described core rod near the left side of described drag groove.
The surface roughness of the convex and described drag groove of described upper model controls within 0.8mm.
Owing to have employed above technical scheme, this utility model has the advantage that
Use upper die and lower die, drag groove, core rod, cylindrical hole, convex designed one or the two grade shift fork finish-forging die that combines of upper model, the equal chamfering of all sharp edges of upper die and lower die becomes 1 × 45 ° of root face, personal injury is not easily caused during work, safety is good, it is provided with core rod near the left side of drag groove, part finish-forging forming efficiency is high, and convex and drag groove the surface roughness of upper model controls within 0.8mm, and the finish-forging precision of part is high.
Accompanying drawing explanation
Fig. 1 is this utility model front-view schematic diagram；
Fig. 2 is this utility model lower mold schematic top plan view；
In figure each assembly and reference be respectively as follows: 1, upper mold；2, lower mold；3, drag groove；4, core rod；5, cylindrical hole；6, upper model is convex.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
A kind of one or two grades of shift fork finish-forging dies, including upper mold 1, lower mold 2, drag groove 3, core rod 4, cylindrical hole 5, upper model convex 6, the matrix of upper mold 1 and lower mold 2 is a cuboid, drag groove 3 is positioned at the upper surface centre position of lower mold 2, and symmetrical front and back, upper model convex 6 is positioned at the lower surface of upper mold 1, upper model convex 6 is also symmetrical front and back, the left back and the right front that are positioned at lower mold 2 are machined with cylindrical hole 5, and lower mold 2 i.e. uses connector to be fixed on lathe, convenient fixing, reliable.
Upper mold 1 becomes 1 × 45 ° of root face with the equal chamfering of all sharp edges of lower mold 2, does not easily cause personal injury during work, and safety is good.
Being provided with core rod 4 near the left side of drag groove 3, part finish-forging forming efficiency is high.
The surface roughness of upper model convex 6 and drag groove 3 controls within 0.8mm, and the finish-forging precision of part is high.
One or two grades of shift fork finish-forging dies disclosed in the utility model, upper mold 1 becomes 1 × 45 ° of root face with the equal chamfering of all sharp edges of lower mold 2, personal injury is not easily caused during work, safety is good, core rod 4 it is provided with near the left side of drag groove 3, part finish-forging forming efficiency is high, and the surface roughness of upper model convex 6 and drag groove 3 controls within 0.8mm, and the finish-forging precision of part is high.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
