Before extruding, part cover for seat is in core rod small end, and part is located on outside element mounting, the core rod that element mounting and part ring are housed is enclosed within outside screw rod, above with nut, be fixed after successively adding bearing and packing ring.After extruding, unclamp nut slide block is opened, take out successively packing ring, bearing and core rod also exit part.
In whole extrusion operation process, need to screw and unclamp nut and open slide block with spanner, hand labor intensity is large, inefficiency, most importantly after extruding, the consistent in density of part ring is poor, sometimes can not meet technological requirement.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is to provide the extrusion die that a kind of automatic degree is high, easy to operate, push the sealing high conformity of rear part ring.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of radial extruding die, comprise patrix, core rod, open washer, pull bar, a plurality of guide plate screws, guide plate, a plurality of telescope-srews, eight push rods that structure is identical, sleeve, eight slide block and die holders that structure is identical, described patrix, core rod, pull bar, guide plate, the axis of sleeve and die holder is all on same straight line, and described patrix, core rod, guide plate and die holder center all have through hole, described patrix and die holder are corresponding up and down, be horizontally disposed with, described guide plate is loaded in the groove of die holder with interference fits, at guide plate top, along the axis of guide plate, be radiant type and be provided with eight identical dovetail grooves, described a plurality of guide plate screw is fixed guide plate and die holder through guide plate, the upper end of described eight slide blocks is all designed to the pyramidal structure matching with the patrix bottom conical surface, lower end is all designed to the trapezium structure matching with guide plate 8 top dovetail grooves, the lower end of described eight slide blocks is all loaded on respectively in eight dovetail grooves of guide plate by matched in clearance, described sleeve is arranged in the circle that eight slide blocks surround, described telescope-srew is fixed sleeve and guide plate through sleeve, on the top of sleeve, be provided with the groove that expands platform with sleeve, in the bottom of sleeve, be provided with eight horizontal grooves that match with described push rod, described horizontally disposed eight push rods be one end can with slide block sliding-contact, the other end can with pull bar sliding-contact, the top of described pull bar is successively through die holder through hole, guide plate through hole, after sleeve, on the top of pull bar, overlap from the bottom to top and have core rod and open washer, at pull bar middle part, being provided with in pull bar uphill process is the guide part of eight push rod guiding, the bottom of pull bar is connected with the piston rod thread of cylinder at the bottom of lathe, described core rod one end diameter is large, one end diameter is little, and one end that core rod diameter is little is relative up and down with the groove of upper cartridge, at the middle part of core rod, be also provided with core rod and expand platform, described open washer is enclosed within the groove of offering on pull bar top.
The guide part structure that described pull bar middle part is provided with is the circular cone of chap gradually of diameter from top to bottom.
The guide part structure that described pull bar middle part is provided with is eight pyramids of chap gradually of diameter from top to bottom, and the respectively corresponding push rod in each side of eight pyramids.
The guide part that described pull bar middle part is provided with also has eight grooves that lead for push rod in pull bar uphill process, and the shape of groove and push rod end adapt, and the position of groove is corresponding one by one with eight push rods.
Compared to the prior art the utility model has following beneficial effect.
One, by pull bar lower end, be connected with the piston rod thread of cylinder at the bottom of lathe, rationally utilized backhaul power and the ejecting force of cylinder piston rod at the bottom of lathe, reduced hand labor intensity, improved operating efficiency.
Two, element mounting is sleeved on to one end that core rod diameter is little with interference fits, and the upper surface of element mounting is expanded you face with core rod and is contacted, then part ring set is contained in to element mounting outside, then the core rod small end that element mounting and part ring are housed is enclosed within outside pull bar down, then open washer is enclosed within the groove on pull bar top and shifts the highest order of groove onto;
Now patrix start descending, simultaneously at the bottom of lathe cylinder piston rod backhaul drive pull bar and open washer descending, open washer contacts gradually core rod upper surface and compresses core rod.Patrix continues descending, patrix bottom conical surface contact slipper, dovetail groove at the squeezing action sliding block of the patrix conical surface along guide plate moves gradually to die holder center, meanwhile, the lower surface of element mounting is expanded you face with sleeve and is contacted gradually, make to form top clearance between the bottom of core rod and the top of sleeve, along with the descending slide block of continuation of patrix touches part ring extrusion sections ring gradually, patrix moves to bottom dead centre and has pushed.
Patrix moves to after top dead center, cylinder piston rod at the bottom of unlatching lathe, at the bottom of lathe, cylinder piston rod upwards ejects, and drive the pull bar and the open washer that are connected to move upward simultaneously, in uphill process, the set guide part in pull bar middle part contacts gradually push rod and promotes push rod and outwards moves, and in the time of push rod motion, with movable slider, outwards moves together along the dovetail groove of guide plate, at the bottom of lathe, cylinder piston rod moves to top dead-centre, and slide block is opened.At this moment, take out open washer and the core rod of part be housed and exit part;
In whole extrusion process, not only easy to operate, operating efficiency is high, and the consistent in density of part is good, and quality meets technological requirement.
Three, by the guide part being provided with at pull bar middle part, open eight grooves for push rod guiding in pull bar uphill process, and the shape of groove and push rod end adapt, the position of groove is corresponding one by one with eight push rods, when pull bar uphill process pull bar guide part touches after push rod, promotion push rod that can be more stable outwards moves.The design of groove has also extended the service life of pull bar simultaneously, avoids without wearing and tearing after long-time use of pull bar of groove design, thereby can not stabilize to push rod guiding, promotes push rod and outwards moves.
