Abstract
The utility model discloses a high-tenacity metal embedded part used in an iron casting and a brake drum. The high-tenacity metal embedded part comprises a high-tenacity metal embedded part body, wherein an anticarburizing protection layer is arranged on the outer periphery surface of the high-tenacity metal embedded part body and is a plating layer formed by a nonferrous metal such as copper, nickel or the like or a coating formed by an anticarburizing painting. The brake drum comprises a brake drum body and the annular high-tenacity metal embedded part combined through a casting manner. The high-tenacity metal embedded part has the benefits as follows: the high-tenacity metal embedded part can be prevented from being carburized in a casting process, so that the tenacity of the metal embedded part can be effectively kept, the tensile strength and the fatigue strength of the iron costing part are improved, the comprehensive mechanical property of the casting is improved, and the service life of the casting is prolonged; and the brake drum of the high-tenacity metal embedded part is long in service life and good in safety.
Description
Technical field
The utility model relates to a kind of reinforcement structure of ironcasting, particularly a kind of for the high-toughness metal embedded part in ironcasting and the brake drum that is provided with this metal embedded part.
Background technique
Ironcasting refers to material cast iron and forms the blank mechanical parts of machined formation again by forging type, or the mechanical parts that directly form by precision casting; Be commonly used for engine cylinder-body, big-and-middle-sized hydraulic cylinder body, big-and-middle-sized cylinder block, the equipment Foundations parts such as brake drum and equipment lathe bed for vehicle.Brake drum has another name called brake drum, and it is particularly important security personnel's parts of lorry driving safety of Motor Vehicle.Because it should form enough braking force with brake shoes, therefore, need enough requirement of strength, also to there is wear-resisting property preferably, therefore usually adopt the cast iron quality manufacture simultaneously.At present, highway transport industry is the unilateral higher income of asking most, often has overload behavior more or less, thereby cause the operating conditions of brake drum to worsen, increase the probability that the brake drum heat fade occurs, caused braking force greatly to reduce, thereby reduced the Safety performance of vehicle.Simultaneously, because bringing braking force, overload increases, to the requirement of strength raising of brake drum, and the hidden danger that serious overload will exist brake drum to break, therefore, various places cause braking effect to descend and the brake drum car crash thing caused of breaking happens occasionally because brake drum produces heat fade.Therefore for improving travel safety, the method and measure aspect brake drum usually have two kinds can and the schemes of use, the one, brake drum is carried out cooling, to reduce its heat fade, guarantee that braking effect does not descend; The 2nd, the intensity of raising brake drum.Its method comprises the measures such as intensity of setting up stiffening rib, increase brake drum structure size, increasing brake drum material.Various schemes respectively have quality, but consider from the angle of sustainable development and reduction manufacture cost, the scheme that stiffening rib is set can be saved materials consumption, be beneficial to sustainable development, the mode of high-toughness metal material particularly is set in the body of brake drum, its advantage is more outstanding, and low cost of manufacture.For this reason, the present inventor had once proposed a kind of application number for " 200820100480.9; the Chinese patent application that invention and created name is " automotive brake hub of built-in metal reinforcer ", and this application has been awarded China Patent Right on September 9th, 2009 on November 6th, 2008.The technological scheme of this patent is embedded with the metal reinforcement of cast steel or alloyed steel exactly in brake hub (being in fact brake drum), cast steel or alloyed steel have lower carbon content, therefore its toughness is higher, improve tensile strength and the fatigue strength of brake drum with this, to stop brake drum, when braking, produce and break.But in actual application, because the high-toughness metal reinforcer of low carbon content is by inserting at the beginning of the casting of brake drum blank in the casting die cavity, in the process of casting brake drum blank, metal reinforcement is wrapped up by high temperature liquid iron, after the molten iron cooled and solidified, makes it embed wherein.And the carbon in cast iron constituent content is higher, reinforcer under high temperature, high-carbon environment by carburizing, its metallographic structure significant change, toughness significantly reduces.Therefore, according to said method its intensity of brake drum of casting can not be significantly improved.For this reason, need to improve.
Summary of the invention
The first purpose of the present utility model is exactly for the deficiencies in the prior art, provides a kind of for the high-toughness metal embedded part in foundry goods, and it not by carburizing, to keep intrinsic tensile strength, thereby improves the tensile strength of foundry goods in the casting process of foundry goods; Second purpose of the present utility model is to provide a kind of brake drum, by arranging not by the pre-embedding metal part of carburizing in its body, to improve brake drum tensile strength.
For realizing the first purpose, the utility model adopts following technological scheme.
A kind ofly for the high-toughness metal embedded part in foundry goods, comprise the high-toughness metal embedded part body, described high-toughness metal embedded part body outer surface is provided with the antiseepage carbon protective layer.
After adopting technique scheme, because the high-toughness metal embedded part outer surface in ironcasting is provided with the antiseepage carbon protective layer, therefore, in the cast casting process, embedded part can be by carburizing, its inside metallographic can obviously not change, therefore its intrinsic toughness and tensile strength can access effective maintenance; Can effectively improve tensile strength and the fatigue strength of foundry goods, thereby the comprehensive mechanical performance of foundry goods is significantly improved.
Described antiseepage carbon protective layer is the coating formed by non-ferrous metals such as copper or nickel or the coating formed by masking paste.
For realizing the second purpose, the utility model adopts following technological scheme.
A kind of brake drum that is provided with the high-toughness metal embedded part; the brake drum body that comprises cast iron quality; be combined with the high-toughness metal embedded part of ring-type in the bulging wall of brake drum body by forging type, described high-toughness metal embedded part outer surface is coated with the antiseepage carbon protective layer.
Described antiseepage carbon protective layer is the coating formed by non-ferrous metals such as copper or nickel or the coating formed by masking paste.
Position and structure shape that the section configuration of high-toughness metal embedded part described in the utility model is positioned ironcasting by it are determined, comprise the shape of various regular and irregulars.
The quantity of high-toughness metal embedded part described in the utility model can be one or more, specifically according to bulging wall construction shape, size, cast iron quality and the performance requirement of brake drum body, and the factors such as the section configuration of high-toughness metal embedded part, size, material are determined.
High-toughness metal described in the utility model refers to that middle low carbon steel, low alloy steel, stainless steel etc. have than the structural steel of low carbon content and higher toughness.
The utility model beneficial effect compared with prior art is, by the high-toughness metal part to being embedded in advance in ironcasting, the antiseepage carbon protective layer is set, it is avoided in the casting process of foundry goods by carburizing, can effectively keep its toughness, to improve tensile strength and the fatigue strength of ironcasting, thus comprehensive mechanical performance and the working life of improving foundry goods; Be provided with the brake drum of this embedded part, its long service life, Security are good.
