Abstract
The invention relates to an automatic compression molding craft for powder metallurgy friction material, which is characterized in that a special mould base for friction material is arranged on the automatic press for powder metallurgy structural component and the special mould base for friction material is used to press a sector friction disk and a sector friction block; the chordal length of the sector friction disk and the sector friction block is below 205mm and the ingredient proportion is Cu 65 to 78, Sn 4 to 8, Pb 0 to 8, Fe 0 to 10, Zn 0 to 7, C 2 to 15, SiO2 (ZrSiO4) 3 to 8. Compared with the prior art, the invention has the advantages of steady performance, high productivity, tidy environment, and other advantages.
Description
Technical field
What the present invention relates to is a kind of automatic extruding forming process of powder metallurgy friction material, is applicable to the automatic extruding moulding that the powder metallurgy pressure is burnt friction plate and brake pad.
Background technology
Domestic traditional powder metallurgical technique flow process is: central layer is electroplated, and---------bisque and central layer pressure sintering moulding---follow-up machined---finished product are put in storage in powder compression moulding in the raw material mixing.Wherein powder compression moulding is to adopt semi-automatic press, the manual mode of scraping powder or claiming powder, and operator's technical merit, working attitude and season directly influence friction material density and performance, and inefficiency.Particularly at hot weather, when the operative employee used fan, dust from flying in the product quality aspect, directly influenced friction material composition and proportioning, finally influences the Properties of Friction Materials index; In the labour protection aspect, the operator sucks dust easily, and is unfavorable in labourer's health.
Summary of the invention
The object of the present invention is to provide a kind of technological process constant, can overcome the deficiency that powder compression moulding operation exists, a kind of brand-new, simple automatic extruding forming technique of powder metallurgy friction material is provided.This process using device on the powder metallurgy structural parts mo(u)ldenpress has the friction material special die carrier, and utilizes this friction material special die carrier to suppress fan-shaped friction plate and brake pad.
The chord length of described fan-shaped friction plate and brake pad is below 205mm.The proportioning components of described fan-shaped friction plate and brake pad is Cu65～78, Sn4～8, Pb0～8, Fe0～10, Zn0～7, C2～15, SiO
2(ZrSiO
4) 3～8.
Characteristics such as the present invention compared with prior art has stable performance, production efficiency height, and environment is clean and tidy.
The specific embodiment
The present invention will be described in detail below in conjunction with specific embodiment: the present invention adopts device friction material special die carrier on the powder metallurgy structural parts mo(u)ldenpress, suppresses fan-shaped friction plate and brake pad.Friction plate and brake pad chord length are below 205mm.The proportioning components of fan-shaped friction plate of the present invention and brake pad is Cu65～78, Sn4～8, Pb0～8, Fe0～10, Zn0～7, C2～15, SiO
2(ZrSiO
4) 3～8.Raw material automatic blanking during compacting, hopper aperture efficiency die cavity chord length is slightly wide, and opening portion and former end face are fitted, and adopt enclosed construction, have solved existing dust from flying situation, can effectively improve working environment.The present invention is a kind of improvement to prior art, and therefore, the content that does not relate among the present invention is perhaps known routine techniques in the known technology, and those skilled in the art just can implement the present invention easily understanding on the basis of the present invention.
