Description
Technical field
The utility model relates to cylindrical shell extrusion molding dies, is specifically related to a kind of mould of flanged pin cylindrical shell.
Background technology
Flanged cylindrical shell, its processing mode is that after cylindrical bar is carried out cold-heading, a forward extrusion is shaping.The shaping usual employing of forward extrusion be forward extrusion mould, the primary structure of forward extrusion mould comprise upper male mould, die, fixing die die holder and be positioned at die and the just right lower punch of upper male mould, conveniently discharging, is also provided with straight pin usually on die in addition.The existing mould for flanged pin cylindrical shell, often has the following disadvantages: due to time extruded, and the extruding force that die bears is comparatively large, and die is normally directly connected with die holder, elastic deformation is comparatively large, and rigidity is poor.
Utility model content
The utility model is intended to the mould providing a kind of flanged pin cylindrical shell, during to solve the work of existing die, and easy elastic deformation, the problem that rigidity is low.
The mould of the flanged pin cylindrical shell in this programme, comprise upper male mould, die holder, be positioned at the die immediately below upper male mould and be positioned at the lower punch of die die cavity, it is characterized in that, the adjustment circle of ring-type is provided with in die cavity, the inner circle at adjustment circle middle part is provided with a circle projection, the lower surface of die has a circle inner groove, the bottom land of inner groove is concordant with adjusting the lower surface enclosed, and all supported by the supporting base of a ring-type, supporting seat is by the second fixed cover supporting of a ring-type, described second fixed cover is positioned on one second cushion block, the periphery of lower punch is provided with annular backing-out punch, the bottom of lower punch has three decile grooves, straight pin is through the second cushion block and decile groove, the upper end of straight pin and the bottom of annular backing-out punch offset, die holder top has mounting groove, described second cushion block, second fixed cover and straight pin are all positioned at mounting groove.
The beneficial effects of the utility model are as follows: in this programme, the bottom of lower punch has three decile grooves, straight pin is through the second cushion block and decile groove, the upper end of straight pin and the bottom of annular backing-out punch offset, during by annular backing-out punch discharging, straight pin is the inner ring acting on annular backing-out punch, makes the motion of annular backing-out punch more stable.Die and adjustment circle are bearing in the mounting groove of die holder by supporting seat, the second fixed cover and the second cushion block, and define the structure that multilayer transmits extruding force step by step, during extruding, the elastic deformation amount of die can reduce, and rigidity increases.
Further, lower punch comprises the larger head of diameter, shank that neck that diameter is less is equal with head with diameter, and head is relative with the projection of adjustment circle.The projection of being enclosed by head and adjustment molds the barrel of cylindrical shell jointly, and lower punch is made with neck, and can take effect frictional force, reduces the shaping rear extruding force applied its barrel of cylindrical shell.
Further, the inner circle of the lower surface of adjustment circle has the conical ring of outside enlarging.During extruding, the inner circle due to the lower surface of adjustment circle has the conical ring of outside enlarging, therefore can not become shaping dead band here.
Further, also comprise push rod, die holder has vertical through hole, push rod upper end has the claw type head of three lobes, and claw type head extend in through hole, and straight pin has three, and each claw type head all offsets with the bottom of a straight pin.Support three straight pins respectively by the head of three claw types, three straight pins withstand the bottom of annular backing-out punch simultaneously, make discharging more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
