Description
Technical field
The utility model relates to a kind of floating die device for sintered metal powder bearing trimmer, belongs to sintered metal powder bearing shaping device field.
Background technology
Utilize the oiliness bearing of powder metallurgy processing and fabricating, due to its have that production cost is low, self-lubricating and production in enormous quantities, be all widely used in motorcycle, electric tool and auto parts and components field.But because the oiliness bearing adopting powder metallurgy to make can produce micro-thermal deformation after sintering, thus the size of oiliness bearing is changed and error, the technological requirement of automobile assembling can not be met.
For addressing this problem, precision truing need be carried out to the powder metallurgy oil-impregnated bearing after sintering, reaching instructions for use to make powder metallurgy oil-impregnated bearing precision.Oiliness bearing is the cylindrical shape of one end with the edge of a wing, and on existing market, trimmer generally adopts and carries out to the oiliness bearing be placed on shaping former the shaping that impact style completes oiliness bearing.But existing shaping former is for being fixedly mounted on trimmer, when upper trimming die carries out punching press to oiliness bearing, its shaping stress concentrates on the step section of shaping former, cause its shaping former platform phase wear faster than other positions, after the wearing and tearing of shaping former, after oiliness bearing depanning, large, the product size precision of size bounce-back is difficult to ensure.For guaranteeing that the machining accuracy of product must frequently change the technological requirement that shaping former could meet automobile assembling.Therefore adopt that this Training system cost is comparatively large, the high needs that can not meet enterprise development of percent defective.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple, easy to maintenance, be applicable to the use of powder metallurgy oil-impregnated bearing precision truing, can solve that the operating cost that existing mode of operation exists is high, error rate is high and the floating die device for sintered metal powder bearing trimmer of problem frequently changed by former.
The technical solution of the utility model is:
For a floating die device for sintered metal powder bearing trimmer, comprise former, former cover, former pressing plate, installing rack and lifting pin; It is characterized in that: frame work top is provided with assembling through hole, the guide blot arranged by symmetry shape in assembling through hole and spring are movably installed with former cover, former is fixed with by former pressing plate in former cover, the centre of former is provided with shaping hole, by installing rack with tighten up adjusting bolt and be provided with Assembly rail below former, locating part is equipped with by installing rack in the top of Assembly rail, is movably installed with lifting pin in locating part; Described Assembly rail is provided with jacking spring, jacking spring contacts with lifting pin and connects.
Described lifting pin is " ⊥ " shape.
Described lifting pin upper end extends in shaping hole.
Described top, shaping hole is provided with and press-fits annular groove.
The utility model has the advantage of:
This is used for the floating die device of sintered metal powder bearing trimmer, and structure is simple, easy to maintenance.The shaping stress distribution originally concentrating on former step section in punching press reforming process can be made during work to cushion in each stage in punching press, thus it is consistent to make former each several part wear and tear, and then improve the service life of former, solve former and need the frequent problem changed, decrease operating cost, improve machining accuracy.Be specially adapted to sintered metal powder bearing trimmer install and use.

Detailed description of the invention
This floating die device being used for sintered metal powder bearing trimmer comprises former 1, former cover 2, former pressing plate 3, installing rack 4 and lifting pin 5.The work top of frame 6 is provided with assembling through hole, the guide blot 7 arranged by symmetry shape in assembling through hole and spring are movably installed with former cover 2, former 1 is fixed with by former pressing plate 3 in former cover 2, the centre of former 1 is provided with shaping hole, and the top in shaping hole is provided with and press-fits annular groove 12.
The work top lower surface of the frame 6 below former 1 is by installing rack 4 and tighten up adjusting bolt 8 and be provided with Assembly rail 9, and locating part 10 is equipped with by installing rack 4 in the top of Assembly rail 9, is movably installed with the lifting pin 5 of " ⊥ " shape in locating part 10; Lifting pin 5 upper end extends in shaping hole.
Assembly rail 9 is provided with jacking spring 11, jacking spring 11 contacts with lifting pin 5 and connects (see accompanying drawing 1).
This floating die device is installed on (see accompanying drawing 2) on the work top below trimmer decompressor by frame 6, during work, after oiliness bearing workpiece 13 is delivered to and put in place by vibration feeding dish and pusher, the pressure head of decompressor moves down, and carries out punching press to oiliness bearing workpiece 13.In this process; Because former cover 2, former 1 have certain downlink spatial, and Assembly rail 9 is provided with jacking spring 11 under the effect of guide blot 7 and spring, jacking spring 11 contacts with lifting pin 5 and connects, therefore; When oil bearing workpiece 13 enters former 1, bottom it with the top contact of lifting pin 5 after, compress lifting pin 5 descending under the descending power effect of pressure head simultaneously, when former cover 2, former 1 and lifting pin 5 is descending put in place after, lifting pin 5 produces reaction force, coordinates the pressure head of decompressor jointly to complete the shaping of oil bearing workpiece 13.
This floating die device is in reforming process, originally the shaping stress distribution concentrating on former 1 step section is cushioning in each stage in punching press, thus it is consistent to make former 1 each several part wear and tear, effectively improve the service life of former 1, solve existing former and need the frequent problem changed, decrease operating cost, improve machining accuracy.Be particularly suitable for sintered metal powder bearing trimmer to install and use.
