Description
Technical field
The invention belongs to continous way atmosphere sintering technical field, particular for the brand-new design of continuous atmosphere sintering device of braking lining product, with continuous, high efficiency and the effectively enhancement friction plate of lining and being tightly combined and stable homogeneous for backboard.
Background technology
The braking system of vehicle, mainly it is made up of disc and piston, and it is provided with lining in piston, disc is incorporated into wheel and therewith synchronous axial system, and disc is then located between piston, piston start is driven by oil hydraulic system start, disc is clamped and reached using the lining located at piston the effect of brake, make vehicle deceleration or stopping.The construction of foregoing lining, include a backboard and a friction plate, the backboard is mostly made up of metal material, the surface of its body is in plane, the surface of the friction plate is also in plane, by friction plate in pasting neat on the body of backboard and bonding, foregoing disc is pressed by the friction plate during brake and brake effect is reached.When in vehicle travel process, disc and wheel synchronous axial system, if now the friction plate of lining presses to disc, the friction plate will bear the reaction force of stop disc rotation, and this reaction force is side force to the direction of exerting pressure of disc relative to friction plate.Found in practice, due to only being fixed between the body of friction plate and backboard with bonding mode, if and the bond strength that this is adhesively fixed is difficult to hold the side force long, the body for causing friction plate and backboard is caused into the damage of lining in bonding place generation slight crack or disengaging in the course of time.
Furthermore, the material of friction plate is usually to refer to the material for driving or stopping mechanical organ, such as clutch Huo Brake car linings；The friction material of early stage nearly all contains asbestos, so in recent years because the environmental protection of asbestos is taken seriously with health problem, it is thus gradually disabled, and then facilitate flourishing for other friction materials, the non-organic base frication material of asbestos, semi-metallic based friction material and metal base frication material etc.；And in recent ten years due to the maturation of PM technique, existing many commercialized commodity, using in the technology manufacture conventional fabrication processes of powder metallurgy, the mixture that the friction material used on braking lining is made up of a variety of adhesives or additive, and insert inorfil and metallic fiber wherein to improve its intensity for different application conditions, play reinforcement effect.
As it was previously stated, friction material can be divided into non-metal base and the major class of Metal Substrate two, traditional non-metal base friction material is mainly asbestos friction material, and environmental pollution and high-temperature stability are bad caused by it, are gradually eliminated in the last few years；Only the mineral composite friction material of non-asbestos is then developed very well.Metal base frication material is divided into elemental metals and powder metallurgy friction material, and the former is primarily referred to as steel, cast iron, bronze etc., and powder metallurgy friction material is then primarily referred to as iron-based, copper-based and Fe Cu based frictional materals.Elemental metals friction material is bonded and the low shortcoming of friction factor under high temperature and high speed due to easy, and replaced by other materials, powder metallurgy friction material has special flexibility and popularity in terms of material mixture ratio, and good friction and wear behavior is shown under high speed, high-load condition, therefore its application is extensive compared with other materials.Powder metallurgy friction material, is addition friction component and lubricant component, the composite being made of powder metallurgy process using metal and its alloy as matrix.Powder metallurgy friction material has enough intensity, suitable and stable coefficient of friction, and stable working is reliable, the advantages of wear-resisting and few pollution, is using one of wide material in modern brake material family.Lining is produced using PM technique, not only there is protrusion in performance quality, also great flexibility in the variation of the design, product in component.The component of material can arbitrarily be changed using PM technique, the casting flaw such as the loose, shrinkage cavity in conventional fabrication processes, the dendritic segregation of material structure and crystal grain can be avoided to grow up is favorably improved every mechanical property of part.Train braking brake shoe is prepared with PM technique and brake lining has achieved very big success, the copper-based powder metallurgy friction material system for main body of P/m Iron Base, copper-based, iron is formd.Powder metallurgy friction material is due to containing the nonmetal objects such as graphite in constituent, therefore sintering densification is difficult, generally uses pressure sintering technique.Only existing lining, the combination of its backboard and friction plate is in addition to the preceding person that adopts bonding mode, mostly adopt and first heat the mode pressurizeed afterwards and combine, in addition to poor bonding strength, the quality stable homogeneous of product can not be ensured, and the densification degree of product, this is for powder metallurgy lining, particularly it is used for racing car, high ferro, the faster powder metallurgy lining of aircraft ... uniform velocity, can not be in sintering process, reach the densification of friction material and realize the strong bonded of friction plate backboard, so in continuous use, lining is easy in the state of high temperature, cause slight crack and the disengaging of friction plate and backboard, cause damage, also it is unable to reach industry continuous, quickly manufacture the demand of high-quality lining, lacked for it.This is the missing that existing located by prior art has maximum, and this missing is into the problem that industry urgently overcomes.
The content of the invention
In order to solve the above-mentioned technical problem, the main object of the present invention is providing a kind of braking lining continuous hot-press sintering equipment.
The braking lining continuous hot-press sintering equipment that the present invention is provided, by body of heater, interior feed track, outer feed track and exchange system are constituted, interior feed track is located at furnace interior, and link the exchange system for being located at the side of body of heater two, outer feed track is outside body of heater, and link the exchange system of the side of body of heater two, interior feed track is provided with slide rail, using the track moved as loading plate, body of heater is closed, and import protective gas, and have disbonded ragion according to processing procedure differentiation, heating zone, hot pressed sintering area, buffering area and cooling zone, disbonded ragion, heating zone, in hot pressed sintering area and buffering area with heat proof material and needed for fabrication procedures temperature heating element heater, disbonded ragion is provided with emission-control equipment, hot pressed sintering area is provided with hot-press arrangement, cooling zone has cooling device, treat that hot-forming braking lining is placed in mould, mould is then placed on loading plate, loading plate enters body of heater and preheats degumming program through disbonded ragion, heating through heating zone again, and to hot pressed sintering area, through hot-press arrangement at high temperature, make lining friction plate and metal backing, by means of the diffusion-sintering of hot pressing in heating of hot-press arrangement, and it is integral to combine closely, transferred again after the cooling in buffered area and the cooling of cooling zone outside body of coming out of the stove, it is stripped and forms again.
