Abstract
The utility model discloses a powder metal forming pressing die with double mandrils. The powder metal forming pressing die with the double mandrils comprises a mandril seat, a locking nut connected to the upper portion of the mandril seat, a lower mandril connected with the locking nut, a lower punch connected to the upper portion of the lower mandril in a sleeved mode, a female die connected to the upper portion of the lower punch and an upper punch connected with the female die in a pressing mode, wherein an upper punch through hole is formed in the position of the axis of the upper punch, the upper punch through hole is connected with an upper mandil in an inserting mode from top to bottom, an inner screw connected with the locking nut is arranged at the top end of the mandril seat, a blind hole is formed in the position of the axis of the inner screw, a compression spring is arranged inside the blind hole, an inner threaded cavity is formed in the lower portion of the locking nut, a nut through hole is formed in the position of the axis of the locking nut, and a shaft collar is arranged at the bottom end of the lower mandril. The powder metal forming pressing die with the double mandrils has the advantages that the elastic design of the lower mandril and the upper mandril structure are creatively added, direct impact force applied to the surface of an inner bore of the bearing of a micromotor is reduced when the bearing of the micromotor is manufactured, the accuracy of the surface of the inner bore of the bearing of the micromotor is improved by more than 10 times, therefore, running noise of the mircomotor can be reduced, and the service life of the mircormotor is prolonged.
Description
Technical field
The utility model relates to mould applications, relates in particular to a kind of twin-core rod powdered-metal moulding compacting tool set.
Background technology
Fig. 1 is existing single plug metal forming compacting tool set, comprise mandrel holder 100, be connected the locking nut 102 on mandrel holder 100 tops, the following plug 104 that is connected with locking nut 102, be socketed in down the following of plug 104 tops and dash 106, be connected down the die 108 that dashes 106 tops, with the upper punch 110 of die 108 crimping.Such structure is being mainly used in processing micro motor bearing, the endoporus of micro motor bearing upwards compresses powdered metal process moulding in the die 108 by following plug 104, the bore area of the micro motor bearing that existing mould structure production and processing is come out is more coarse, with cause noise big after the rotating shaft of micro machine is connected, it is bigger to wear and tear, and the life-span is shorter.Require further improvement and improve.
The utility model content
The purpose of this utility model is, overcomes the above-mentioned defective of prior art, and a kind of novel structure is provided, and promotes the twin-core rod powdered-metal moulding compacting tool set of processing micro motor bearing bore area precision.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of twin-core rod powdered-metal moulding compacting tool set, comprise mandrel holder, be connected the locking nut on mandrel holder top, the following plug that is connected with locking nut is socketed in down the following of plug top and dashes, be connected down the die of the portion of rushing to, with the upper punch of die crimping, place, upper punch axle center offers the upper punch through hole, is plugged with plug in the upper punch through hole from top to bottom; Be provided with the inner screw that is connected with locking nut on the mandrel holder top, the place, axle center of inner screw offers blind hole, and blind hole is built-in with the compression spring; Offer the internal thread chamber in the locking nut bottom, the place, axle center of locking nut offers the nut through hole, and following plug bottom is provided with the axle collar.
Following plug from the bottom to top with the locking nut cross-under, the axle collar top of following plug is connected to the top in the internal thread chamber of locking nut, the axle collar bottom of following plug and compression spring top elasticity crimping.
The axle collar bottom face of following plug and the inner screw top of mandrel holder stay face that the gap of 0.1mm to 20mm is arranged.
Usefulness of the present utility model is, on the basis of existing structure, mandrel structure is gone up in the Flexible Design of plug and increase under the creationary increase, when the production and processing micro motor bearing, reduce the direct impulsive force to the micro motor bearing bore area, thereby the precision of micro motor bearing bore area is carried more than 10 times, be conducive to reduce micro machine operation noise and prolong the micro machine life-span.
