Abstract
The utility model discloses a kind of core shaft die forging cone-shaped inner hole spheroidal graphite bearing holder (housing, cover), it is characterized in that: it is shaft-like, it is made up of front cylindrical section, frustum section and rear cylindrical section, the central axis of front cylindrical section, the central axis of frustum section and the central axes of rear cylindrical section, the tapering of frustum section is identical with the tapering of the cone-shaped inner hole of the spheroidal graphite bearing holder (housing, cover) of processing.Described front cylindrical section is identical with the cross section diameter of rear cylindrical section；The cross section diameter of the rear end of described frustum section is the maximum gauge on frustum section axis, and more than the diameter of bore of spheroidal graphite bearing holder (housing, cover).This utility model simple in construction, easy to use, can directly forge the cone-shaped inner hole that inner surface is smooth, make follow-up machining be easier to, surplus is little, has saved machining time and expense, decreases the waste of material, also reduces labor intensity.
Description
Technical field
This utility model relates to the production mould of a kind of cone-shaped inner hole spheroidal graphite bearing holder (housing, cover), belongs to technical field of forging, a kind of core shaft die forging cone-shaped inner hole spheroidal graphite bearing holder (housing, cover), it is adaptable to the forging processing to the spheroidal graphite bearing holder (housing, cover) blank of cone-shaped inner hole.
Background technology
Spheroidal graphite bearing holder (housing, cover) is the forging that endoporus is tapered, and traditional forging mode is that blank is swaged into the straight barrel type that endoporus is parallel with external diameter, sectional view as shown in Figure 1；Then being processed on lathe, by bevel out, its tapering is a, sectional view as shown in Figure 2.The defect of this processing mode is: when endoporus is machined into taper, and metal material resection is big, and machining difficulty is big, many during institute's work consuming, improves processing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, the core shaft die of forging cone-shaped inner hole spheroidal graphite bearing holder (housing, cover) easy to use, forge cone-shaped inner hole spheroidal graphite bearing holder (housing, cover) time more convenient, simultaneously, inner hole of workpiece surface after forging is round and smooth, and directly forms cone-shaped inner hole, and follow-up machining is easier to, surplus is little, and waste of material is few.
In order to reach object above, this utility model be the technical scheme is that this kind of core shaft die forging cone-shaped inner hole spheroidal graphite bearing holder (housing, cover), it is characterized in that: it is shaft-like, it is made up of front cylindrical section, frustum section and rear cylindrical section, the central axis of front cylindrical section, the central axis of frustum section and the central axes of rear cylindrical section, the tapering of frustum section is identical with the tapering of the cone-shaped inner hole of the spheroidal graphite bearing holder (housing, cover) of processing.
Described front cylindrical section is identical with the cross section diameter of rear cylindrical section；The cross section diameter of the rear end of described frustum section is the maximum gauge on frustum section axis, and more than the diameter of bore of spheroidal graphite bearing holder (housing, cover).
The beneficial effects of the utility model are: this utility model simple in construction, easy to use, can directly forge the cone-shaped inner hole that inner surface is smooth, making follow-up machining be easier to, surplus is little, has saved machining time and expense, decrease the waste of material, also reduce labor intensity.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of spheroidal graphite bearing holder (housing, cover) blank in prior art.
Fig. 2 is the structure cross-sectional schematic of cone-shaped inner hole spheroidal graphite bearing holder (housing, cover).
Fig. 3 is structure schematic front view of the present utility model.
Fig. 4 is use view of the present utility model.
Detailed description of the invention
Making this utility model with reference to Fig. 3, with processing cone-shaped inner hole spheroidal graphite bearing holder (housing, cover) as shown in Figure 2, its tapering is a.This kind of core shaft die forging cone-shaped inner hole spheroidal graphite bearing holder (housing, cover), it is characterized in that: it is shaft-like, it is made up of front cylindrical section 1, frustum section 2 and rear cylindrical section 3, the central axis of front cylindrical section 1, the central axis of frustum section 2 and the central axes of rear cylindrical section 3, the tapering of frustum section 2 is b, the tapering of frustum section 2 is identical with the tapering of the cone-shaped inner hole of the spheroidal graphite bearing holder (housing, cover) of processing, i.e. a=b.
Described front cylindrical section 1 is identical with the cross section diameter of rear cylindrical section 3；The cross section diameter of the rear end of described frustum section 2 is the maximum gauge on frustum section 2 axis, and more than the diameter of bore of spheroidal graphite bearing holder (housing, cover).
When using this utility model, such as Fig. 4, by spheroidal graphite bearing holder (housing, cover) blank jumping-up punching, the little 50mm of maximum inner diameter that aperture ratio spheroidal graphite bearing holder (housing, cover) requires, again spheroidal graphite bearing holder (housing, cover) blank is set in frustum section 2, embrace pincers 4 with operation machine and clamp front cylindrical section 1, prevent spheroidal graphite bearing holder (housing, cover) blank from slipping, and spheroidal graphite bearing holder (housing, cover) blank is pushed into the rear end of frustum section 2, the outer wall of frustum section 2 is made to be in close contact with the inner hole wall of spheroidal graphite bearing holder (housing, cover) blank, front cylindrical section 1, frustum section 2 keeps level vertical with spheroidal graphite bearing holder (housing, cover) blank with rear cylindrical section 3, guarantee the interior of spheroidal graphite bearing holder (housing, cover) blank, external diameter is concentric, use " V " swage block 5 and under " V " swage block 6 that ink bearing holder (housing, cover) blank is carried out operate pulling is the most plastic, reaming or shell nosing treatment is done again according to molding situation.Owing to spheroidal graphite bearing holder (housing, cover) kind is more, this utility model can do several different sizes, owing to front cylindrical section 1 is identical with the cross section diameter of rear cylindrical section 3, in order to uses during waistcoat reaming.
