Abstract
The utility model discloses a powder metallurgy split die for a rotor of a variable oil pump. The split die comprises a round body provided with an outer-diameter profile and an inner-diameter profile, wherein blade grooves extending in the radial direction are formed in the circumference of the round body; a plurality of inward recessed grooves are formed in the outer-diameter profile, located in two sides of each blade groove respectively and separated from the blade grooves; and a plurality of outward recessed concave parts are formed on the inner-diameter profile, located on two sides of each blade groove respectively and communicated with the blade grooves. Through change of the profile shape design, the die splitting gaps of the powder metallurgy die avoid the assembly positions of the blade grooves, so that burrs produced in the die gaps cannot influence assembly and working of blades and block pieces.
Description
Technical field
The utility model relates to a kind of variable oil pump rotor powder metallurgy parting.
Background technology
When automobile vacuum pump blade rotor adopts powder metallurgy manufacturing process, as shown in Figure 1, existing powder metallurgy parting designs its external diameter profile and internal diameter profile is smooth circular arc, vacuum pump rotor, in the time adopting powder metallurgical technique to manufacture, adopts mould in entirety to design fragile because mould has thin-walled; And can, because exist point die clearance to produce burr in the position at blade groove place, affect assembling and the running of blade and catch in the time adopting in split mould design.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, a kind of variable oil pump rotor powder metallurgy parting is provided, by contour shape design change, the burr producing because of die clearance make a powder metallurgy die point die clearance avoid blade groove place rigging position, so that can not affect assembling and the work of blade and catch.
For achieving the above object, the technical solution of the utility model has been to provide a kind of variable oil pump rotor powder metallurgy parting, comprise circular body, described circular body has external diameter profile and internal diameter profile, the circle distribution of described circular body has the blade groove radially extending along it, on described external diameter profile, offer and be equipped with some grooves that cave inward, described groove lays respectively at the both sides of each described blade groove and is separated with described blade groove, in described internal diameter profile, offer the depression of some outside depressions, described depression lays respectively at the both sides of each described blade groove and is connected with described blade groove.
As preferably, described groove is deep-slotted chip breaker.
Advantage of the present utility model and beneficial effect are: with the assembling of blade and catch in avoided existing design and the stuck situation of the not genial use Leaf of assembling that the burr that produces brings, can make assembly line efficiency higher, vacuum pump failure rate reduces.
Brief description of the drawings
Fig. 1 is prior art schematic diagram;
Fig. 2 is schematic diagram of the present utility model;
Fig. 3 is partial schematic diagram of the present utility model.
Wherein: 1, circular body; 2, external diameter profile; 3, internal diameter profile; 4, blade groove; 5, groove; 6, depression.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As Fig. 2, shown in Fig. 3, a kind of variable oil pump rotor powder metallurgy parting, comprise circular body 1, described circular body 1 has external diameter profile 2 and internal diameter profile 3, the circle distribution of described circular body 1 has the blade groove 4 radially extending along it, on described external diameter profile 2, offer and be equipped with some grooves that cave inward 5, described groove 5 lays respectively at the both sides of each described blade groove 4 and is separated with described blade groove 4, in described internal diameter profile 3, offer the depression 6 of some outside depressions, described depression 6 lays respectively at the both sides of each described blade groove 4 and is connected with described blade groove 4, described groove 5 is deep-slotted chip breaker.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a variable oil pump rotor powder metallurgy parting, it is characterized in that, comprise circular body, described circular body has external diameter profile and internal diameter profile, the circle distribution of described circular body has the blade groove radially extending along it, on described external diameter profile, offer and be equipped with some grooves that cave inward, described groove lays respectively at the both sides of each described blade groove and is separated with described blade groove, in described internal diameter profile, offer the depression of some outside depressions, described depression lays respectively at the both sides of each described blade groove and is connected with described blade groove.
