Description
Technical field
The present invention relates to piston and make part field, be specifically related to a kind of cast iron edge circle.
Background technique
Piston is motor " heart ", bears the mechanical load and the heat load of alternation, is one of worst key components and parts of operating conditions in the motor.In order to improve the working life of piston, people are made all-aluminium piston into cast-iron piston.The aluminium annular groove has made the cast iron annular groove into like this, and wear resistance greatly improves.But the weight that designs back piston like this is multiplied, motional inertia strengthens, and connecting rod, bent axle, bearing shell and even whole motor are brought a lot of adverse effects.So people gently combine cast-iron piston heat resistant and wear resistant damage, aluminium piston weight, cylinder iron do an abrasion-proof inserted ring at the piston ring groove position, castingin is entered during the casting piston, and the piston remaining part is still used aluminum alloy.Such piston, its annular groove decreases as the cast iron heat resistant and wear resistant, and weight is light as aluminum alloy.
Bond quality between piston only materials of aluminum matrix and the cast iron edge circle is the key factor that influences piston mass.If piston bonding between piston only and the cast iron edge circle in manufacture process is bad, piston in use is easy to generate loosening between cast iron edge circle and the aluminium piston, then may cause piston ring land to rupture, power failure and can not working.
In the mechanical processing process of piston, when the machining piston annular groove, cast iron edge circle receives the machining external force of tangential, and cast iron edge circle has the tendency of peeling off with aluminum substrate.The reject that produces owing to the processing annular groove is the main source of all rejects in the piston machine course of working.
With reference to Fig. 1, Fig. 1 .1, Fig. 2, existing cast iron edge circle inner side surface 1 is rotary surface, and like smooth cylndrical surface, upper side 2 is a rotary surface also with downside 3, like smooth flat.This surface is that the cast iron edge circle of turning surface is resisted the indifferent of tangential machining power.Because cast iron edge circle has certain difference with aluminium piston only material coefficient of thermal expansion coefficient; Under the effect of the mechanical load of alternation and cooling and heating load; If the bonding between cast iron edge circle and the piston only is bad; Then have between cast iron edge circle and the aluminium piston to produce loosening possibility, become flexible then may cause piston ring land to rupture, power failure and can not working in case produce.
Summary of the invention
The objective of the invention is to, a kind of discontinuous rotary surface cast iron edge circle is provided, solve above technical problem.
The technical problem that the present invention solved can adopt following technological scheme to realize:
Discontinuous rotary surface cast iron edge circle comprises an edge circle main body, and said edge circle main body is circular, it is characterized in that, the inner side surface of said edge circle main body is discontinuous turning surface.
The inner side surface of said edge circle main body is provided with convexity or groove, or is the wave of fluctuating.
The upper side of said edge circle main body is discontinuous turning surface.Preferably, the upper side of said edge circle main body is provided with convexity or groove, or is the wave of fluctuating.
The downside of said edge circle main body is discontinuous turning surface.Preferably, the downside of said edge circle main body is provided with convexity or groove, or is the wave of fluctuating.
Edge circle main body is cast in the aluminium piston crown as embedded piece, is used to improve the hot strength and the wear resistance at annular groove position.The present invention produces convexity or groove or awave fluctuating characteristic through machining or on-mechanical method for processing at inner side surface, upper side or the downside of edge circle.It is more tight that the discontinuous turning surface on this edge circle surface combines edge circle and piston aluminum substrate, can bear bigger tangential operating force, effectively reduces the reject quantity in the piston machine processing.In the using process of piston, improve the ability that opposing cast iron edge circle is peeled off the piston only material, improve the reliability of piston.While more helps the piston crown heat and spreads out of from inlaying circle owing to increased the area of contact of edge circle with aluminum substrate, thereby reduces the head temperature of piston, improves the reliability of piston.
Said discontinuous turning surface can be located at inner side surface or the upper side or the downside of edge circle separately.Also can be located at inner side surface, upper side and the downside of edge circle simultaneously.Also can be located at inner side surface and upper side or the inner side surface and the downside of edge circle simultaneously.Also can be located at edge circle upper side and downside simultaneously.
Said edge circle main body is processed for adopting austenitic cast iron.So that increase the wear resistance of edge circle main body.
Said edge circle main body is processed for adopting high-nickel austenitic cast iron.The hot expansion system and the aluminium material of high-nickel austenitic cast iron are approaching, can further reduce the loosening of edge circle main body or come off.
Beneficial effect: owing to adopt technique scheme; The present invention can make the edge circle combine more tight with aluminum substrate; Can bear bigger cutting force, reduce the reject in the piston manufacture process, reduce in the using process owing to edge circle main body is peeled off the failure likelihood that aluminum substrate takes place; Reduce the piston crown temperature simultaneously, improve the reliability of piston.
