The utility model provides a solenoid valve wide-angle turn-ups riveting die based on pre-compaction function, its is including lower mould and last mould, be equipped with the clamping position that is used for placing the solenoid valve on the lower mould, it is located to go up the mould the top of lower mould, the riveting hole has been seted up to the bottom of going up the mould, be formed with the taper inner wall in the riveting hole, be equipped with the elasticity prepressing mechanism that can elastically stretch out and draw back from top to bottom in the riveting hole, work as when going up the mould and descending, elasticity prepressing mechanism pushes up the tip part of tight solenoid valve earlier to make the tip part of solenoid valve get into in the casing, again to go up mould and lower mould loading pressure, borrow by the taper inner wall in riveting hole is with.

Preferably, the clamping position is a through hole penetrating through the upper end and the lower end of the lower die.

Preferably, the top opening edge of the clamping position is formed with an inner chamfer.

Preferably, the elastic pre-pressing mechanism is a spring.

Preferably, the top of the upper die is provided with a mounting column which can be mounted on the punch press.

Preferably, the riveting hole is a blind hole.

The utility model discloses a solenoid valve wide-angle turn-ups riveting die based on pre-compaction function adds man-hour carrying out the riveting, packs into the clamping position with the solenoid valve earlier, then the punch press orders about last mould and lower mould and is close to each other, and it is downthehole until the tip part entering riveting of solenoid valve elasticity is compressed tightly tip part elasticity in the casing under the effect of elasticity prepressing mechanism, later by the punch press to go up mould and lower mould loading riveting pressure under the effect of taper inner wall, with the casing turn-ups riveting shaping of solenoid valve. Compared with the prior art, the utility model discloses a processing mode of pre-compaction then riveting can be fast with solenoid valve riveting shaping, can prevent effectively that solenoid valve housing fold, deformation, and not only the yield is high, has saved the processing cost moreover greatly.

Detailed Description

The present invention will be described in more detail with reference to the accompanying drawings and examples.

The utility model discloses a big angle turn-ups riveting die of solenoid valve based on pre-compaction function combines fig. 1 to 5 shown, and it is including lower mould 1 and last mould 2, be equipped with the clamping position 3 that is used for placing solenoid valve 100 on the lower mould 1, it is located to go up mould 2 the top of lower mould 1, riveting hole 4 has been seted up to the bottom of going up mould 2, be formed with taper inner wall 40 in the riveting hole 4, be equipped with elasticity prepressing mechanism 5 that can stretch out and draw back from top to bottom in the riveting hole 4, work as when going up mould 2 and descending, elasticity prepressing mechanism 5 pushes up tight solenoid valve 100's tip part 102 earlier to make solenoid valve 100's tip part 102 get into in the casing 101, again to go up
