Abstract

The utility model discloses a kind of brake plunger fine forge piece, comprise cylindrical cup-shaped piston only, it is characterized in that: the inner chamber of piston only is large and small circular cylindrical cavity and their adapter cavity, and great circle cylindrical chamber is positioned at piston only upper end open place.Metal forming technology is applied to brake plunger manufacture, reduce follow-up cutting, save resource and processing technology is simple, constant product quality, comprehensive mechanical performance are good, manufacturing efficiency is high, can required precision be met, again reduce manufacture cost, also meet the trend of world today's development of manufacturing simultaneously.

Description

Brake plunger fine forge piece
Technical field
The utility model relates to brake plunger, particularly relates to a kind of brake plunger fine forge piece.
Background technique
Brake plunger is the main slide member of automobile brake system, during braking, piston moves, oil pressure raises, transfer mechanical energy to by hydraulic energy and promote wheel braking, require very high to its accuracy of manufacturing and bulk strength, China Intellectual Property Office CN102686763A discloses a kind of manufacture method of brake plunger, relates to a kind of brake plunger of cup-shaped.General employing selects the direct Vehicle Processing of bar at present, then hole Milling Process inner chamber and bottom, and this kind of method manufacturing efficiency is low, waste raw material, and cost of production is high, particularly because raw material metal streamline is cut-off, comprehensive mechanical performance is reduced.
Summary of the invention
The utility model provides a kind of and adopts finish forge forming technique, and manufacturing efficiency is high, save material, cost of production is low, the brake plunger fine forge piece that especially comprehensive mechanical performance is good.
The utility model realizes by following technical solution:
Brake plunger fine forge piece, comprises cylindrical cup-shaped piston only, it is characterized in that: the inner chamber of piston only is large and small circular cylindrical cavity and their adapter cavity, and great circle cylindrical chamber is positioned at piston only upper end open place.
The concrete structure of great circle cylindrical chamber is the cavity being similar to cylindrical structural that two sections of corresponding corresponding circular arcs arranged of straight line and both sides arranged are formed.
The outside of described piston only is positioned at that glass bottom is also corresponding is provided with two arc grooves upwards extended.
Two described arc grooves are corresponding with the straight line in great circle cylindrical chamber.
The utility model compared with prior art has following beneficial effect:
Metal forming technology is applied to brake plunger manufacture by the utility model, reduce follow-up cutting, save resource and processing technology is simple, constant product quality, comprehensive mechanical performance are good, manufacturing efficiency is high, can required precision be met, again reduce manufacture cost, also meet the trend of world today's development of manufacturing simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment,
Fig. 2 is the plan view of Fig. 1,
Fig. 3 is the worm's eye view of Fig. 1.
Sequence number in figure: 1, great circle cylindrical chamber, 2, small cylindrical cavity, 3, adapter cavity, 4, arc groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1, shown in Fig. 2 and Fig. 3, a kind of brake plunger fine forge piece, comprise cylindrical cup-shaped piston only, the inner chamber of piston only is large, small cylindrical cavity 1, 2 and their adapter cavity 3, great circle cylindrical chamber is positioned at piston only upper end open place, the concrete structure of great circle cylindrical chamber is the cavity being similar to cylindrical structural that two sections of corresponding corresponding circular arcs arranged of straight line and both sides arranged are formed, the outside of described piston only is positioned at that glass bottom is also corresponding is provided with two arc grooves 4 upwards extended, two described arc grooves 4 are corresponding with the straight line in great circle cylindrical chamber 1.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not form the restriction to the utility model protection domain; every do not depart from technical solutions of the utility model interior perhaps above scheme is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong within the utility model protection domain.
