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 chopper, for controlling the flowing of the sulfur hexafluoride gas in chopper；
Spout blank is suppressed by mould and is formed, and because spout is hollow tubular structure, is provided with die core axle in spout compacting tool set.
Existing stripping means rely on demoulding frame cooperation forcing press to realize, and forcing press is provided with the top of downward top pressure spout
Bar, in an initial condition, push rod lower end should be higher than that the height of mould；Push rod is hollow bar, and the internal diameter of push rod is more than the outer of mandrel
Footpath；Demoulding frame is provided with the material-dropping hole falling for workpiece, and during in order to ensure that spout falls on demoulding frame bottom surface, spout is completely from mould
Deviate from tool, the height between demoulding body panel and demoulding frame ground should be greater than the height of spout；In order that the mandrel in spout
When spout is deviate from from mould, the mandrel in spout can together be taken off, and de- bin bottom surface is provided with the mandrel in spout
The connecting rod of block contact.
Existing stripping means mainly comprise the steps that and manually mould are transported on demoulding frame, adjust die location
Spout is aligned with the material-dropping hole on demoulding frame；In the pressure head of spout upper end pad loop configuration, the looping pit of pressure head is more than mandrel
Diameter；Forcing press drives depression bar to push pressure head, and demoulding frame forms the positioning to mould, and the position of mould is motionless, and pressure head drives
Spout moves down；Mandrel is connected masthead and lives, and together will not move down with spout, mandrel is contained within the endoporus of depression bar；When spout and
After pressure head departs from completely from mould, under gravity, both fall on the base plate of demoulding frame.
Existing stripping means are there is problems in that need manually mould to be carried to demoulding frame after the completion of the compacting of 1, spout
On, mold weight is heavier, and labor strength is big, and easily causes mold impingement and impact in handling process, causes spray
Mouth internal soundness hidden danger；2nd, because the distance between demoulding body panel and demoulding frame base plate are larger, what workpiece was subject to when falling rushes
Hit larger；3rd, because pressure head needs to transmit the larger pressure on depression bar, so the quality of pressure head itself is larger；Pressure head falls in spray
On mouth, spout is impacted；When the 4th, operating, the process of connecting rod top pressure mandrel cannot be observed, and pressure head is misaligned with connecting rod.
However, just compressing shower nozzle is not also sintered the process of recrystallization, the structure of spout is not fine and close, intensity
Relatively low；Existing stripping means, the impulsive force that spout is subject to is larger, easily causes the damage of spout.
Content of the invention
It is an object of the invention to provide a kind of stripper apparatus, it is subject to due to spout with solving that existing stripper apparatus exists
To the problem that is easily damaged of the larger, spout of impact.
For achieving the above object, the technical scheme of the stripper apparatus of the present invention is:
