Description
Technical field
This utility model relates to a kind of closed mould for forging automobile bearing, belongs to forging processing technique field.
Background technology
Currently in automobile bearing is processed, generally using open die, open die i.e. has the die forging of overlap, and it is made up of movable mold and fixing mould, and moving downward by movable mold is extruded, promotes metal to fill up whole die cavity.The most unnecessary metal can form overlap around forging, it will usually uses the mode of trimming to go deburring, it is thus achieved that complete forging.But often there is following defect and deficiency in this die forging having overlap:
(1) stock utilization is low；Open die forging, impressing forging can produce overlap in technique, thus reduces stock utilization, improves cost.
(2) die life is low；Open die forging, impressing forging is in forging process, and metal fluidity is strong, easily causes mould loss, reduces die life, thus improve cost.
(3) labour demand is high；In whole forging, relatively big to the demand of operative employee's quantity, it is unfavorable for cost control.
Utility model content
For overcoming above-mentioned the deficiencies in the prior art, this utility model provides a kind of closed mould for forging automobile bearing.
This utility model adopts the technical scheme that: a kind of closed mould for forging automobile bearing, it includes upper die and lower die and the die cavity between upper mold and lower mold, described upper mold includes cover die and is positioned at the upper padding plate below cover die, the first upper mold core, the second upper mold core, the 3rd upper mold core and upper mounted plate, described first upper mold core, the second upper mold core, the 3rd upper mold core are interconnected by the way of step fastens, and are compressed by upper mounted plate；Described lower mold includes lower cover die, the first lower mold core, the second lower mold core, lower bolster, T-shaped backing plate, bottom plate and thimble, described lower bolster and T-shaped backing plate are positioned at the inside of lower cover die, described first lower mold core, the second lower mold core are positioned at the top of lower bolster, and interconnecting by the way of step fastens and compressed by bottom plate, described thimble is through the first lower mold core, lower bolster and the inside of T-shaped backing plate and can be freely up and down movable.
Being provided with groove in the middle part of the lower end of described upper cover die, described first upper mold core, the second upper mold core, the top of the 3rd upper mold core and upper padding plate are sequentially located in described groove.
Fixed plate compresses the 3rd upper mold core and is threadedly attached on cover die.
Described bottom plate compresses the second lower mold core and is threadedly attached on lower cover die.
Described first upper mold core, the second upper mold core and the 3rd upper mold core stretch into the inside of the second lower mold core, and the outer wall of the 3rd upper mold core and the contact internal walls of the second lower mold core connect.
The beneficial effects of the utility model are:
(1) stock utilization is improved；Closed-die forging does not produce overlap, and utilization rate of raw materials tends to 100%, thus reduces material cost.
(2) improve die life；It is more scientific that closed-die forging makes metal flow in mold cavity, more rationally, thus reduces die cost.
(3) labour demand is reduced；Closed-die forging, owing to not producing overlap, therefore eliminates trimming operation, thus reduces labor cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-the first upper mold core, 2-the second upper mold core, 3-the 3rd upper mold core, cover die on 4,5-upper padding plate, 6-upper mounted plate, 7-the first lower mold core, 8-the second lower mold core, cover die under 9-, 10-lower bolster, 11-T type backing plate, 12-bottom plate, 13-thimble.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of closed mould for forging automobile bearing, it includes upper die and lower die and the die cavity between upper mold and lower mold, described upper mold includes cover die 4 and is positioned at upper padding plate the 5, first upper mold core the 1, second upper mold core the 2, the 3rd upper mold core 3 and the upper mounted plate 6 below cover die 4, described first upper mold core the 1, second upper mold core the 2, the 3rd upper mold core 3 interconnects by the way of step fastens, and is compressed by upper mounted plate 6；Described lower mold includes lower cover die the 9, first lower mold core the 7, second lower mold core 8, lower bolster 10, T-shaped backing plate 11, bottom plate 12 and thimble 13, described lower bolster 10 and T-shaped backing plate 11 are positioned at the inside of lower cover die 9, described first lower mold core the 1, second lower mold core 8 is positioned at the top of lower bolster 10, and interconnecting by the way of step fastens and pass through bottom plate 12 and compress, described thimble 13 is through the first lower mold core 7, lower bolster 10 and the inside of T-shaped backing plate 11 and can be freely up and down movable.
Being provided with groove on this utility model in the middle part of the lower end of cover die 4, top and the upper padding plate 5 of described first upper mold core the 1, second upper mold core the 2, the 3rd upper mold core 3 are sequentially located in described groove.Fixed plate 6 compresses the 3rd upper mold core 3 and is threadedly attached on cover die 4；Described bottom plate 12 compresses the second lower mold core 8 and is threadedly attached on lower cover die 9.Described first upper mold core the 1, second upper mold core 2 and the 3rd upper mold core 3 stretch into the inside of the second lower mold core 8, and the outer wall of the 3rd upper mold core 3 and the contact internal walls of the second lower mold core 8 connect.
Closed die forging process of the present utility model can be divided into three phases: the first stage is first shaping stage, and second stage is packing stage, and the phase III is to form longitudinal flash stage；It mainly passes through moving downward of activity upper mold, completes whole deformation process.Wherein: the drafts of first stage upper mold is △ H1, upper mold contact with blank, till blank starts to be deformed to blank and impression sidewall contact, this stage deformation force increase is slower.The drafts of second stage upper mold is △ H2, the first stage, terminating to be full of impression to metal, this stage deformation force increases 2-3 times than the first stage, but drafts △ H2 is the least.The drafts of phase III upper mold is △ H3, and now, blank substantially has become as indeformable rigid body, and end metal only just can be made under the effect of great Die Forging to be deformed, and forms longitudinal flash.
This utility model is not directed to part and the most same as the prior art prior art maybe can be used to be realized.
