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 cold straight 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, delivery bothers, precision is low, affect the service life of driving parts, cost is high, therefore design is a kind of easy to operate, safety is good, the correction accuracy of part is high, shape convenient one or two grades of shift fork cold straight dies and 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 troublesome defect of delivery, devises a kind of one or two grades of shift fork cold straight dies, and easy to operate, safety is good, and the correction accuracy of part is high, and it is convenient to shape.
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 cold straight dies, including upper die and lower die, the matrix of described upper mold and described lower mold is a cuboid, also include shift fork root type groove, shift fork rod-type groove, dial plug-type groove, described shift fork root type groove is positioned on rear side of the lower surface of described upper mold middle on rear side of the middle upper surface with described lower mold, being close to described shift fork root type groove is the described shift fork rod-type groove being symmetrical set, and described group of plug-type groove is positioned at the end of described shift fork rod-type groove.
Described upper mold becomes 1 × 45 ° of root face with the equal chamfering of all sharp edges of described lower mold.
The surface roughness of described shift fork root type groove, described shift fork rod-type groove and described group of plug-type groove controls within 0.8mm.
Described shift fork rod-type groove is seen as a semicircle type groove from overlooking direction, and the described shift fork rod-type groove band of described upper mold is gradient.
Described group of plug-type groove is seen as a circular type groove from left view direction, consistent with dialling plug shape.
Owing to have employed above technical scheme, this utility model has the advantage that
Use upper mold, lower mold, shift fork root type groove, shift fork rod-type groove, dial plug-type groove to combine designed one or two grade shift fork cold straight die, 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, shift fork root type groove, the surface roughness of shift fork rod-type groove and group plug-type groove controls within 0.8mm, the correction accuracy of part is high, shift fork rod-type groove is seen as a semicircle type groove from overlooking direction, the shift fork rod-type groove band of upper mold is gradient, shifting fork bar shapes convenient, dial plug-type groove and be seen as a circular type groove from left view direction, consistent with dialling plug shape, dial plug forming accuracy high, it is convenient to shape.
Accompanying drawing explanation
Fig. 1 is this utility model lower mold schematic top plan view；
Fig. 2 is this utility model left view complete section schematic diagram；
In figure each assembly and reference be respectively as follows: 1, upper mold；2, shift fork root type groove；3, lower mold；4, shift fork rod-type groove；5, plug-type groove is dialled.
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 cold straight dies, including upper mold 1, shift fork root type groove 2, lower mold 3, shift fork rod-type groove 4, dial plug-type groove 5, the matrix of upper mold 1 and lower mold 3 is a cuboid, shift fork root type groove 2 is positioned on rear side of the lower surface of upper mold 1 middle on rear side of the middle upper surface with lower mold 3, being close to shift fork root type groove 1 is the shift fork rod-type groove 4 being symmetrical set, shift fork rod-type groove 4 is symmetrical, dial plug-type groove 5 and be positioned at the end of shift fork rod-type groove 4, upper mold 1 and lower mold 3 matched moulds can realize being corrected one or two grades of shift forks, easy to operate.
Upper mold 1 becomes 1 × 45 ° of root face with the equal chamfering of all sharp edges of lower mold 3, does not easily cause personal injury during work, and safety is good.
The surface roughness of shift fork root type groove 2, shift fork rod-type groove 4 and group plug-type groove 5 controls within 0.8mm, and the correction accuracy of part is high.
Shift fork rod-type groove 4 is seen as a semicircle type groove from overlooking direction, and the shift fork rod-type groove 4 of upper mold 1 carries gradient, and shifting fork bar shapes convenient.
Dial plug-type groove 5 and be seen as a circular type groove from left view direction, consistent with dialling plug shape, dial plug forming accuracy high, it is convenient to shape.
One or two grades of shift fork cold straight 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 3, personal injury is not easily caused during work, safety is good, shift fork root type groove 2, the surface roughness of shift fork rod-type groove 4 and group plug-type groove 5 controls within 0.8mm, the correction accuracy of part is high, shift fork rod-type groove 4 is seen as a semicircle type groove from overlooking direction, the shift fork rod-type groove 4 of upper mold 1 carries gradient, shifting fork bar shapes convenient, dial plug-type groove 5 and be seen as a circular type groove from left view direction, consistent with dialling plug shape, dial plug forming accuracy high, it is convenient to shape.
