Develop towards miniaturization, the basic size of components is smaller and smaller, magnitude of interference the subtracting with basic size of interference connection
It is small and reduce.The firm reliability of interference riveting, the persistence that product uses will substantially reduce in this way.
Interference stamping riveting technique is generally included for the direct solenoid mechanism riveting in direct solenoid system at this stage
And laser welding process.Interference stamping riveting technical matters is the process that punching parts and the part that is stamped are in a stress
In, the stamping press that part is subject to the big, and a possibility that deforming is bigger.Laser welding technology technique is soldering part and is soldered
A heated process melted at part combination gap, since laser welding is in external soldering part combination gap.Part by
A possibility that non-uniform situation of heat increases then rosin joint, hollow weldering is bigger.
Direct solenoid mechanism includes a variety of components: two moving armatures, a moving armature column, a coil, a pole shoe,
One magnet ring.It needs to rivet or increase by two, three pre- riveter simultaneously for above several parts when producing the riveting of direct solenoid mechanism
It is riveted again after skill together, this stamping riveting requires Sheet Metal Forming Technology accurate, and the required precision of riveting equipment mould is high, but technique
It is comparatively laborious.In stamping riveting actual production, direct solenoid mechanism is easy to appear between oblique armature riveting, armature and pole shoe and rivets
Gap, armature column, which occurs, in riveting between appearance gap, armature and magnet ring will appear the feelings such as internal stress, appearance deformation by impact
Condition, influence magnetic property make direct solenoid system can not act actuation or can not releases situation.It is rushed during stamping riveting
Pressure equipment pressure control is bad to be easy for damage coil, and to operating personnel, there is also some potential safety problemss.Laser welding also needs
It to be first riveted together and be welded again, centre can not eliminate welding gap, be easy situations such as there are rosin joints, hollow weldering, make electricity
Magnetic system brings magnetic resistance leakage field larger, under the conditions of manufacture riveting process is horizontal generally, riveting process equipment precision is general, this
The movement that two kinds of conventional coupling arrangements of kind all affect direct solenoid system to a certain extent (is attracted or discharges) stability, together
When can greatly enhance the probability for burning electromagnetic system.

Two blocks of moving armatures and coil are fixed in lower placement；
Step 3: by the mounting hole of the moving armature column quick insertion moving armature by step 1 processing, the upper end of moving armature column
The upper surface 0.2-0.4mm of top moving armature is stretched out in portion, and the following table of lower part moving armature dome platform is stretched out in the lower end of moving armature column
Face 0.2-0.4mm；
Step 4: clamping the both ends of the surface of moving armature column with rotation aerostatic press, starting rotation aerostatic press drives moving armature pillar height speed
Rotation heats the position blowing hot-air that moving armature column is close with moving armature mounting hole and dome platform with air-heater, hot blast temperature
It is 20-30 DEG C, gradually dilatancy, outer wall are held in the mouth with dynamic at the position that moving armature column is close with moving armature mounting hole and dome platform
The inner wall of iron mounting hole and dome platform is in contact, and high speed rotary grinding generates high temperature, accelerates the deformation velocity of moving armature column end；
Aerostatic press is rotated simultaneously to press to two end faces of moving armature column, pressure 50Mpa, make the upper surface and top of moving armature column
The fitting of moving armature upper surface closed seamless, makes the close nothing in lower surface of the lower end surface of moving armature column and the moving armature dome platform of lower part
Seam fitting, be filled with moving armature mounting hole in process edge occur shearing fillet, complete moving armature column with
The seamless connection of moving armature.
Preferably, the rotation aerostatic press rotation speed is 2500-3000 revs/min.
Preferably, the moving armature column and moving armature value of interference fit are 0.08-0.12mm.
The present invention utilizes the principle of metal heat-expansion shrinkage, and the both ends of moving armature column are seamlessly connected with moving armature, letter
Processing step is changed, has been not necessarily to riveting/welding, improves the connection precision, stability and reliability of direct solenoid system, realize
Direct solenoid system compact.
