Abstract
The utility model discloses a disconnected quenching and tempering forged steel connecting rod can rise. The disconnected technology that rises makes the connecting rod become whole processing by components of a whole that can function independently processing, has saved technologies such as parting surface broaching and grinding, has reduced the machining precision and the processing cost of bolt hole, has improved economic benefits. The utility model discloses enlarge the scope of the disconnected processing connecting rod that rises, guaranteed the quality of producing the connecting rod, reduced the cost of production connecting rod again, had wide application prospect.
Description
Technical field
The utility model discloses one can rise disconnected modified forged steel connecting rod, expanding the scope of the disconnected processing connecting rod that rises.
Background technology
Engine link rise disconnected process technology be in the world connecting rod produce advanced technology, at present, apply wide forged steel connecting rod material and mainly have C70S6 high-carbon middle carbon microalloy pearlitic steel, SPLITASCO series forged steel, FRACTIM forged steel and S53CV-FS forged steel etc., but owing to the existing disconnected processing quenched and tempered steel connecting rod technology that rises cannot ensure to rise the structure of the plane of disruption of having no progeny, making to cover during follow-up assembling to become difficulty with engaging of body, therefore the disconnected process technology that rises seldom applied by current modified forged steel connecting rod.
Utility model content
The purpose of this utility model is contemplated to solution and rises by disconnected processing for the not applicable problem of modified forged steel connecting rod, it is provided that one can rise disconnected modified forged steel connecting rod.
This utility model disconnected modified forged steel link feature that can rise is in that: connecting rod forging big end hole is circle, and forging has V-groove at big end hole place.This utility model is achieved through the following technical solutions technical goal.
The course of processing of modified forged steel connecting rod is as follows: blanking → sensing heating → roller forging sheet stamping → blocking → finish-forging → edge-cutting and hole-punching → correction → remnant forging thermal quenching → tempering → check → rise disconnected and following process.
When forging, connecting rod forging big end hole is circular, when connecting rod edge-cutting and hole-punching operation, forms V-groove (see Fig. 1) at big end hole place.When connecting rod correction operation, form the groove of wide 2 millimeter (see Fig. 2) (degree of depth 1.5～3 millimeters, optionally determine) in the major part disconnected place upper and lower surface that rises.When immediate quenching, V-groove place can crack due to stress concentration, and crackle will extend along groove direction.Can separate in cracks when rising disconnected.
Accompanying drawing explanation
The accompanying drawing constituting the part of the application is used for providing being further appreciated by of the present utility model, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is that this utility model can rise disconnected modified forged steel connecting rod front view.
Fig. 2 is the left view of Fig. 1.
In figure: 1-V type groove；2-groove
Detailed description of the invention
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In conjunction with shown in Fig. 1 and Fig. 2, can rise disconnected modified forged steel connecting rod according to this utility model, comprise the steps:
1. pressing quenched and tempered steel connecting rod material and select suitable quenching liquid, the material property to reach modified back link reaches requirement.
2. the course of processing of modified forged steel connecting rod is as follows: blanking → sensing heating → roller forging sheet stamping → blocking → finish-forging → edge-cutting and hole-punching → correction → remnant forging thermal quenching → tempering → check → rise disconnected and following process.
3., when connecting rod edge-cutting and hole-punching operation, form V-groove (see Fig. 1) at big end hole place.
4., when connecting rod correction operation, form the groove of wide 2 millimeter (see Fig. 2) (degree of depth 1.5～3 millimeters, optionally determine) in the major part disconnected place upper and lower surface that rises.
5., when quenching, V-groove place can crack due to stress concentration, and crackle will extend along groove direction.Can separate in cracks when rising disconnected.
6. carry out rise disconnected and following process.
Claims (1)
1. the disconnected modified forged steel connecting rod that can rise, it is characterised in that: connecting rod forging big end hole is circular, and forging has V-groove at big end hole place.
