Abstract
The invention discloses a cylinder step notch cast iron insert for casting. A body is of a cylinder step structure and is formed by connecting a first cylinder and a second cylinder, wherein the diameter of the first cylinder is larger than that of the second cylinder. A center hole is formed in the body and penetrates through the body, and the center hole is formed by a sand core. At least one notch is formed in the surface of the first cylinder. A plurality of shallow grooves are formed in the surface of the second cylinder, and the depth of the shallow grooves ranges from 0.05 mm to 0.6 mm. Inner grooves are formed in the surface of the body and are parallel. According to the cast iron insert, the sand core is adopted for manufacturing during casting, and the center hole is directly obtained; later machining is omitted, the labor cost is reduced, and a machining device is not abraded or consumed; the strength of contact between the insert and an aluminum alloy piece is increased, the insert and the aluminum alloy piece are firmly connected together and cannot loose, and the potential safety hazards of rotation components or power components are eliminated.
Description
Technical field
The present invention relates to a kind of cast iron inserts, particularly a kind of using for the aluminium alloy part such as automobile, motorcycle cast use
Cylinder step otch cast iron inserts.
Background technology
In casting field, such as all employ part Al alloy parts, to mitigate total quality on automobile, motorcycle etc.；With
When, require higher part for some, cast iron inserts are set up on Al alloy parts, as iron core, in casting or die casting
Contact with aluminium liquid, or surrounded by aluminium liquid, and one-shot forming obtains the Al alloy parts with cast iron inserts.This kind of workpiece, both had
There are light weight, the good heat-transfer of aluminium alloy, have the advantages that ironcasting is wear-resisting, thermal expansion is relatively low again.As partly rubbed
The Al alloy parts of motorcycle brake, part motorcycle cylinder first-class it is simply that having the Al alloy parts of cast iron inserts.Single, existing
The cast iron inserts of the fine size of technology, such as cylinder within 40mm for the diameter, there is a diameter wherein within 20mm
Centre bore, therefore is all to make a cylindrical solid casting in casting because centre bore is less it is impossible to core pulling, then passes through
Machining obtains centre bore.This kind of mode, first, casting solid casting, it is necessary to melt molten metal, consumes energy etc. more；
Secondly, increased machining processes, increased abrasion and the consumption of mach cost of labor and process equipment；Further, machine adds
Man-hour also can produce waste product, correspondingly reduce the qualification rate of inserts, therefore all increase the cost of inserts on the whole it is impossible to meet city
Field and the needs of user.Meanwhile, the combination between inserts and Al-alloy parts is insecure, there is loosening danger in life-time service
Danger, for rotatable parts or power part, there is certain hidden danger.
Content of the invention
The invention aims to a kind of knot solving the above problems and providing does not need machining, casting to directly obtain
Casting cylinder step otch cast iron inserts.
To achieve these goals, the cylinder step otch cast iron inserts of the casting designed by the present invention, including body, its
Be characterised by, described body is cylinder step-like structure, connected and composed by the first cylinder and the second cylinder, the first cylinder straight
Footpath is more than the diameter of the second cylinder；Centre bore is provided with body, centre bore runs through body, centre bore is obtained by core molding
Arrive；On the surface of the first cylinder, it is provided with least one otch；
The surface of the second cylinder is provided with some shallow slots, the depth of shallow slot is 0.05-0.6 mm, is on body surface
Inner groovy, be arranged in parallel each other.
Further feature is, the diameter parallel of described shallow slot and centre bore, vertically arranged on body surface.
The axes intersect of described shallow slot and centre bore at an angle, is obliquely installed on body surface.
Compared with prior art, the casting cylinder step otch cast iron inserts that the present invention obtains have the advantage that
1st, made using core in casting, directly obtain centre bore；Eliminate the machining in later stage, reduce artificial one-tenth
This, and process equipment is not worn and torn and consumes；
2nd, in casting, every all decreases molten metal, and the molten metal of thawing is just corresponding to be reduced, and has saved energy etc..
3rd, shallow slot and otch are provided with inserts, so that contact strength between inserts and Al-alloy parts is increased, firmly connect into
Integrally, will not loosen, eliminate the potential safety hazard of rotatable parts or power part.
Brief description
Fig. 1 is the front view of the step-like cast iron inserts of cylinder in embodiment；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Embodiment:
The casting cylinder step otch cast iron inserts that the present embodiment provides, as shown in Figure 1, 2, it includes body 1, body
1 is cylinder step-like structure, is made up of the unequal cylinder of two sections of diameters, forms stepped cylindrical body structure；I.e. by
One cylinder 11 and the second cylinder 12 connect and compose, the diameter with diameter greater than the second cylinder 12 of the first cylinder 11；Body 1 sets
It is equipped with centre bore 2, centre bore 2 runs through body 1, centre bore 2 passes through core one-shot forming, that is, in casting, arrange in die cavity
Core is taken out after cast or is processed through knockout, is the formation of centre bore 2 at core position by core；In the first cylinder 11
Surface on, be provided with least one otch 4, otch 4 is on the surface of the first cylinder 11, according to circle profound direction carry out
Cutting, obtains cutting groove；If two otch 4, then according to this profound parallel diametric(al), be symmetrical arranged.Otch 4, from
One end of first cylinder 11 extends to the other end.Body 1 is that cylinder is step-like, and in 20-40mm, length is 15-50mm to its external diameter；
The diameter of centre bore 2 is in 8-20mm；
The surface of the second cylinder 12 is provided with some shallow slots 3, the depth of shallow slot 3 is 0.05-0.6 mm, is body 1 table
Inner groovy on face, be arranged in parallel each other；Its structure has two kinds, and a kind of diameter parallel setting with centre bore 2, in body
Vertically arranged on 1 surface；Another kind of not parallel with the axis of centre bore 2, the second cylinder 12 surface is obliquely installed, with center
The axes intersect in hole 2 is at an angle.
The present invention, in the case of not affecting body 1 intensity, is provided with shallow slot 3 and otch 4, can more increase body 1 with
Adhesion between Al alloy parts；And, using this inserts as stress or tumbler use when, due to the presence of otch 4, cast
Can not rotate between ironware and Al-alloy parts.
Finally it should be noted that above example is only in order to illustrate technical scheme rather than restriction technologies side
Case, although applicant has been described in detail to the present invention with reference to preferred embodiment, those of ordinary skill in the art should manage
Solution, those are modified to technical scheme or equivalent, the objective without deviating from the technical program and scope,
All should cover in the middle of scope of the presently claimed invention.
