Abstract
The utility model discloses a perforation jar for extruder, it includes the master cylinder body, plunger and piston assembly, the plunger is fixed in the master cylinder is internal, seted up the inner chamber on the plunger, wherein, piston assembly includes piston rod, piston and perforation cylinder front cover, the perforation cylinder front cover is fixed in the open end of inner chamber, the piston rod passes the perforation cylinder front cover sets up, the piston install in the piston rod is located one end in the inner chamber, the other end of piston rod passes through the connecting piece and connects the perforation roof beam. Above -mentioned a perforation jar for extruder regards plunger itself as the cylinder body of perforation jar, overall processing cost greatly reduced, secondly plunger after as the perforation jar perforation jar hole enlarge and still have sufficient wall thickness to the in -service use demand after, after at last having processed the pore on the plunger inner wall, the pipeline no longer need be arranged in plunger inside, and the equipment pipe arrangement will make things convenient for a lot, and the security is high, easy maintenance.
Description
Technical field
The utility model belongs to extruder manufacturing technology, more particularly, to a kind of perforation cylinder for extruder.
Background technology
Be traditionally used for the perforation cylinder of extruder be process after be installed in the inner chamber of plunger.The assembling of this kind of perforation cylinder
Mode has the disadvantage that in specific application：
1) individually forging processes the relatively costly of cylinder of boring a hole；
2) in order to want proof strength, just may require that plunger and the wall thickness of cylinder of boring a hole can not be excessively thin, can thus limit perforation
The diameter of cylinder endoporus, affects maximum puncture force parameter；
3) when being related to perforation cylinder distribution pipes, filling in the pipeline in chamber needs in plunger body arrangement, narrow space, and including needing
Processing technology groove on wall.
Utility model content
The purpose of this utility model is to provide a kind of perforation cylinder for extruder, and it has a simple structure, low cost,
It is safe and be easy to the characteristics of assembling and keep in repair, to solve prior art in the presence of extruding machine punching cylinder the problems referred to above.
It is that, up to this purpose, the utility model is employed the following technical solutions：
A kind of perforation cylinder for extruder, it includes Master cylinder body, plunger and piston component, and the plunger is fixed on described
In master cylinder body, inner chamber is offered on the plunger, wherein, the piston component includes piston rod, piston and perforation cylinder front cover, institute
The openend that perforation cylinder front cover is fixed on the inner chamber is stated, the piston rod is arranged through the perforation cylinder front cover, the piston
The one end of the piston rod in the inner chamber is installed on, the other end of the piston rod is by connector connection perforation beam.
Especially, plug chamber oil inlet passage is offered on the plunger.
Especially, the piston is fixed on the piston rod by piston unt and locking flat key.
Especially, the connector adopts adapter sleeve, coordinates the end that the connection is placed on the piston rod to be provided with company
Joint, the connector is arranged in the adapter sleeve and is connected piston rod with adapter sleeve.
Especially, the perforation cylinder front cover is fixed on the plunger by cylinder gland of boring a hole, and the plunger passes through master cylinder
Gland is fixed on the Master cylinder body.
Especially, rod chamber oil inlet passage is opened up on the perforation cylinder front cover.
The beneficial effects of the utility model are, compared with prior art the perforation cylinder for extruder is by plunger itself
As the cylinder body of perforation cylinder, with advantages below：
1) without the need for individually one perforation cylinder of forging processing, manufacturing cost is reduced, simplifies the entirety of extruding machine punching cylinder
Structure；
2) after plunger is as perforation cylinder cylinder body, perforation cylinder endoporus is amplified to after actually used demand still enough wall thickness,
Maximum puncture power is not interfered with；
3) after machined duct on plunger inwall, pipeline no longer needs to be arranged in plunger body, and equipment pipe is prepared will
It is convenient many and safe, it is easy to maintenance.
Description of the drawings
Fig. 1 is the structural representation of the perforation cylinder for extruder that the utility model specific embodiment 1 is provided.
