Abstract
The utility model relates to a powder metallurgy connecting rod forged piece preformed piece of an engine, wherein 2 V-shaped gaps are symmetrically formed on an inner circle of a big head end of the powder metallurgy connecting rod forged piece preformed piece of the engine, and the included angle of the two side edges of the V-shaped gaps ranges from 50 to 70 DEG. The powder metallurgy connecting rod forged piece preformed piece of the engine has a simple structure, can effectively reduce processing procedure after repeated processing, enables two processed surfaces to be completely matched, and saves time, labor and resource.
Description
Technical field
The utility model relates to the connecting rod manufacturing of motor, particularly a kind of motor powder metallurgy connecting rod forging preformed member.
Background technique
The engine link forging preformed member of making at present, circle is not provided with " V " type breach in the connnecting rod big end end, when making engine link is to wait instrument to cut connnecting rod big end end use saw; Face after reprocessing is cut, after this processing, face is too smooth; Dislocation easily, when in use, two faces are not easy to coincide; This engine link forging preformed member in processing once more, time-consuming also effort, and moulding is bad.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, through adding man-hour once more, can effectively reduce manufacturing procedure, and the motor powder metallurgy connecting rod forging preformed member of easy-formation.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of motor powder metallurgy connecting rod forging preformed member, comprise connecting rod, and connecting rod one end is a stub end, it is characterized in that: the circle symmetry offers 2 " V " type breach in the stub end.
The angle number of degrees of the dual-side of said " V " type breach are between 50 °-70 °.
The beneficial effect of the utility model is: simple in structure, through adding man-hour once more, can effectively reduce manufacturing procedure, and process latter two face and be prone to coincide, reach time saving and energy saving, aim of saving.
Description of drawings
Fig. 1 is the structural representation of the utility model:
1 connecting rod, 2 stub end 3 " V " type breach among the figure.
Embodiment
A kind of motor powder metallurgy connecting rod forging preformed member comprises that connecting rod 1, connecting rod 1 one ends are stub end 2, and the circle symmetry offers 2 " V " type breach 3 in the stub end 2.
The angle number of degrees of the dual-side of said " V " type breach 3 are between 50 °-70 °.
The utility model directly adopts the hydraulic pressure device that swells to inject circle in the stub end 2 when being processed into motor powder metallurgy connecting rod finished product, and it is disconnected that stub end 2 is expanded from " V " type breach 3, also can adopt external force to break from " V " type breach 3.
" V " type breach 3 of the utility model cannot be located at stub end 2 and connecting rod 1 join domain, if be located at stub end 2 and connecting rod 1 join domain after fracture, will influence engine connecting rod structure, and engine link can't normally be used.
Claims (2)
1. a motor powder metallurgy connecting rod forging preformed member comprises connecting rod (1), and connecting rod (1) one end is stub end (2), it is characterized in that: the circle symmetry offers 2 " V " type breach (3) in the stub end (2).
2. according to claims 1 said a kind of motor powder metallurgy connecting rod forging preformed member, it is characterized in that: the angle number of degrees of the dual-side of said " V " type breach (3) are between 50 °-70 °.
