Description
Technical field
The present invention relates to a kind of bearing riveting technology, be specifically related to a kind of copper rivet bearing flexible riveting tool and technique.
Background technology
Based on the high-revolving applying working condition of aero dynamo bearing, the retainer of current domestic electric machine bearing mainly uses phenolic aldehyde
Ebonite tube processes, and fully alleviates retainer weight on the basis of ensureing bearing performance.Coordinate double half retainer of this type
The rivet major part of riveted uses the copper rivet that ductility is good.The riveted of this type of rivet is generally individually by having been manually done at present.
Aero dynamo bearing Manual riveting mode is divided into two steps: rivet bar instantaneous stamping is first formed rivet with moulding punching pin by the first step
Cap, second step reduces its requirement highly reaching technical papers with flat punching pin further punch rivet crown end and completes copper rivet
Bearing riveted.Rivet bar generation local plastic deformation during Manual riveting, easily there are the phenomenons such as askew nail, burr in rivet after rivet joint head,
Riveting quality is uneven；Operator's amount of labour intensity is high, fatiguability, and the bearing after riveted easily exists potential safety hazard, Er Qiexiao
Rate is low.
Summary of the invention
After the present invention is to solve existing bearing Manual riveting, easily there is askew nail, burr in manufactured head, the long-time labor of operator

Being connected with screwing and packing ring, the lower end of support is connected with lower screw, and bearing location tire is arranged on the upper surface of base, bearing
The upper surface of location tire is provided with annular protrusion, annular protrusion be provided with first time riveted punching just to the punching of second time riveted
Hole, the punching of lower riveted is arranged in first time riveted punching and second time riveted punching, and location tire is arranged in hole, location, upper riveted
Punching be arranged on location tire in, upper riveted punching upper and lower side all be exposed at position tire outside, latch segment, spring, riveted cap by under
The supreme upper end being sleeved on riveted punching successively, riveted cap rushes with upper riveted threadeds.
Copper rivet bearing flexible technique for riveting, described technique through the following steps that realize:
Step one, bearing binding: copper rivet bearing flexible riveting tool is positioned on high-precision pressure machine, by retainer
Being placed in the upper of annular protrusion, rivet passes retainer, and the upper end of rivet bar is the most right with the punching of upper riveted, the lower end of rivet bar and lower riveting
Syzygies is the most right；
Step 2, it is pressed against rivet: starting the pressure head on high-precision pressure machine, pressing speed under pressure head is 2.5mm/s～3mm/
S, stroke coordinate precision 0.01mm, pressure head drives and presses, until the upper end of rivet bar 5 forms riveting under riveted cap and the punching slowly of upper riveted
Close cap.
The present invention compared with prior art comprises and provides the benefit that:
One, the present invention utilizes frock to achieve the mechanical riveted to bearing, uses forcing press to determine journey riveted, and rivet bar is in pressure
Under head slowly effect the most at the uniform velocity, the Impact direction in whole plastic history all the time with the axis of rivet bar at same straight line
On, the impossible local plastic deformation of rivet bar, it is manual for increasing the effective contact area between rivet bar 15 and rivet hole
1.5 times of riveted so that riveted intensity is compared Manual riveting and improve more than 50%.
Two, the rivet cap riveting quality formed after utilizing riveted of the present invention is good, and concordance is strong, rivet cap size scattered error energy
Enough control within 0.03mm, produce without torticollis, burr phenomena.
Three, the frock highly versatile of the present invention, contains current all copper rivet bearings, only needs during different model bearing riveted
Change bearing location tire, substantially increase riveted efficiency.
Four, slow flexible plastic mode of texturing maintains the original metal streamline of copper rivet, the rivet cap impulse-free robustness of formation
Produce, eliminate the potential safety hazard during bearing uses.
