Description
Technical field
The present invention relates to a kind of stripper apparatus.
Background technology
High-voltage switch gear spout is mainly used in SF6 breakers, the flowing for controlling the sulfur hexafluoride gas in breaker；
Spout blank is suppressed to be formed by mold, and since spout is hollow tubular structure, die core axle is equipped in spout compacting tool set.
Existing stripping means coordinate forcing press to realize by demoulding frame, and forcing press is equipped with the top of downward top pressure spout
Bar, in the initial state, mandril lower end should be higher than that the height of mold；Mandril is hollow bar, and the internal diameter of mandril is more than the outer of mandrel
Diameter；Demoulding frame is equipped with the material-dropping hole fallen for workpiece, and in order to ensure that spout is fallen when on demoulding frame bottom surface, spout is completely from mould
Deviate from tool, demoulds the height that the height between body panel and demoulding frame ground should be greater than spout；In order to make the mandrel in spout
When spout is removed from the mold, the mandrel in spout can be taken off together, and de- material frame bottom surface is equipped in the mandrel in spout
The connecting rod of block contact.
Existing stripping means mainly include the following steps that：Manually mold is transported on demoulding frame, adjusts die location
By the material-dropping hole on spout and demoulding frame to just；The pressure head of loop configuration is padded in spout upper end, the looping pit of pressure head is more than mandrel
Diameter；Forcing press drives compression bar to push pressure head, and demoulding frame forms the positioning to mold, and the position of mold is motionless, and pressure head drives
Spout moves down；Mandrel is connected bar and withstands, and will not together be moved down with spout, mandrel is contained in the endoporus of compression bar；When spout and
Pressure head in mold completely after being detached from, and under gravity, the two is fallen on the bottom plate of demoulding frame.
Existing stripping means have the following problems：1, it after the completion of spout compacting needs that mold is manually carried to demoulding frame
On, mold weight is heavier, and labor intensity is big, and be easy to cause mold impingement and impact in the handling process, causes to spray
Mouth internal soundness hidden danger；2, since demoulding the distance between body panel and demoulding frame bottom plate are larger, what workpiece was subject to when falling rushes
It hits larger；3, since pressure head needs to transmit the larger pressure on compression bar, so the quality of pressure head itself is larger；Pressure head, which is fallen, to be sprayed
On mouth, spout is caused to impact；The process of connecting rod top pressure mandrel can not be observed when 4, operating, and pressure head is misaligned with connecting rod.
However, the nozzle of just compression moulding is not sintered the process of recrystallization also, the structure of spout is not fine and close enough, intensity
It is relatively low；Existing stripping means, the impact force that spout is subject to is larger, easily causes the damage of spout.
Invention content
