Description
Technical field
The invention belongs to warhead parts-moulding technical field, relate to a kind of bonding forming mould, particularly a kind of fragmentation bonding forming device.
Background technology
The element of fragmentation artillery warhead is explosive and fragmentation, after explosive charge, fragmentation is driven to obtain very high speed, high speed fragments directly clashes into target, rely on fragmentation Kinetic Energy Kill target, the advantage such as have that density is large, speed is high due to fragmentation and armor-penetrating ability is strong, therefore, by increasingly extensive be used as antipersonnel ammunition kill and wound element, the fragmentation artillery warhead field such as to kill and wound in air defense, antiradiation, face has a wide range of applications.Fragmentation can target kill and fragmentation shape and arrangement mode closely related, therefore, the application technology of fragmentation is the key technology of design fragmentation artillery warhead.
At present, spherical fragmentation is applied in warhead mainly through the mode of bonding forming, the people such as Wang Yingchun are at the document experimental study of high density tungsten alloy brokenness " under the explosively loading condition " (Arms Material scientific and engineering, in January, 2003,26th volume the 1st phase 40 pages) in report a kind of fragmentation adhesive moulding technique, after tungsten fragmentation, metal dust are mixed in preset shaping mould with adhesive, sinter molding in stove.Following problem is there is in the method in bonding fragmentation process:
(1) after fragmentation has been arranged in mould, when the upper port place encapsulating of mould, because the stickiness of glue is comparatively large, is easy to block in port, the air between fragmentation and dies cavity cannot be got rid of, make fragmentation cannot bonding forming.
(2), after fragmentation sinter molding, fragmentation and firm the bonding together of mould, for mould and fragmentation mask work bring inconvenience, molded fragmentation module is easily torn by forced demoulding.
Summary of the invention
In order to overcome shortcomings and deficiencies of the prior art, the invention provides a kind of fragmentation adhesive mould possessing exhaust and demoulding functions, the quality of fragmentation bonding forming can be ensured, and in knockout course, guarantee the integrality of shaping fragmentation.
Spherical fragmentation bonding forming mould provided by the invention, comprise soket head cap screw, encapsulating velar plate, enclose cylinder and punch, it is characterized in that, also comprise die, the described cylinder that encloses is cylinder, the upper and lower end face of cylindrical shell is all processed with the uniform screwed hole of circumference, and the upper surface of enclosing cylinder is connected with die by soket head cap screw, and the lower surface of enclosing cylinder is connected with punch by soket head cap screw; Punch is shell structure, and upper surface is parabola, and lower surface is taper seat, and the edge of punch, with a circle outward flange, outward flange is processed with uniform screwed hole and uniform manhole; Die is the shell structure with central circular through hole, upper surface is taper seat, lower surface is parabola, the edge of die is with a circle outward flange, outward flange is processed with uniform screwed hole and uniform manhole, manhole place, with a circle inner flange, inner flange is processed with uniform screwed hole; The inner flange of die is connected with encapsulating velar plate by soket head cap screw, and encapsulating velar plate is the plectane with central circular boss, is processed with uniform manhole and uniform screwed hole along its circumference, and the height of round boss is identical with the inner flange thickness of die.
The screwed hole of described die is positioned at the outer edge place of inner flange.The screwed hole of described die, the screwed hole of punch and the screwed hole enclosing a upper and lower end face are identical nominal diameter and pitch.Described die is equal with punch wall thickness, with enclose barrel thick ratio be 1.5 ~ 2:1.
Spherical fragmentation bonding forming mould of the present invention, the technique effect brought is presented as:
(1) be designed with exhaust outlet in the upper end of mould, during encapsulating, the air between fragmentation and dies cavity can be got rid of from exhaust outlet, thus guarantees that the space between fragmentation and fragmentation, between fragmentation and mould is fully filled with glue, ensure that the quality of fragmentation bonding forming.
(2) on mould, demoulding mouth is designed with, when using the demoulding mouth demoulding, mould is by the uniform pulling force of circumference, and mould and fragmentation split displacement can accomplish controllable precise, effectively reduce risk fragmentation integrality being caused to damage, thus guarantee the integrality of shaping fragmentation in knockout course.
