Description
Technical field
The utility model relates to easy-to-draw lid and covers punch press basically, is specifically related to a kind of easy-to-draw lid and covers the basic lid diel of using on the punch press basically, and said basic lid diel is the light lid form that is used to stamp out easy-to-draw lid.
Background technology
The Along with people's growth in the living standard, canned food is more and more, and the demand of the easy-to-draw lid of its metal is also increasing.For easy-to-draw lid manufacturer, adopting which kind of easy-to-draw lid production equipment is the key with output of ensuring the quality of products.
See that from the manufacturing process of easy-to-draw lid the first step is exactly will the metal charge material be become one by one lid basically through basic lid punch ram, so-called basic lid is commonly called as " light lid ", is meant monnolithic case molded but also not groove and the lid of riveting draw ring.Though basic lid is a lid just; But in order to improve its voltage endurance capability; Still comparatively complicated on its structural design; Conventional basic lid structure is: the frustum structure that begins to become to the body design that extend at the center indent on the lid from circular periphery; And see from the lid cross section, be followed successively by the envelope tank field from lid periphery to center,, form annular groove between the section of immersing oneself in and the capel section of extending upward to the center capping of the section of immersing oneself in that extends below, the capel arc section, the capel section of extending upward and the level that turn to.
For once stamping out above-mentioned basic lid, just need design the diel that matches, existing basic lid diel is external import, and its core technology is maintained secrecy, and is with high costs, and the design of domestic basic lid diel still is blank.
Summary of the invention
The utility model purpose provides a kind of easy-to-draw lid and covers diel basically, with the production needs of satisfied basic lid, and reduces cost.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of easy-to-draw lid covers diel basically, is made up of upper die and lower die;
Said counterdie mainly by die shoe, lower mold core ring, lower mold core, down the binder ring and down cutter forms, said die shoe is last uncovered cylindrical shell, said lower mold core ring is an annular solid, be fixed at die shoe interior and with the die shoe concentric; Said lower mold core is embedded in the lower mold core ring, and the below sealing of the inherent lower mold core of lower mold core ring forms one first air chamber, is supporting lower mold core with the air pressure of this first air chamber; Said down binder ring is an annular solid, and its ring is embedded between die shoe and the lower mold core ring, and between die shoe and the lower mold core ring below binder ring down sealing form one second air chamber, supporting the binder ring with the air pressure of this second air chamber; Said cutter down is an annular solid, and its last uncovered edge of being fixed in die shoe is last, sets blade on the interior edge at its top; Be provided with one between the top of the top of said lower mold core and lower mold core ring and be used for the space of dodging that capel is shaped;
Said patrix mainly is made up of upper bolster, upper mold core, last binder ring and upper slitter, and said upper bolster is the cylindrical shell of lower open mouth; Said upper mold core is fixed at the center in the upper bolster; The bottom of upper mold core and the top of said lower mold core are relative up and down; And the outer rim of the bottom end face of upper mold core is provided with a circle to the flange of lower convexity, this flange with said be used for the capel shaping to dodge the space relative; Said last binder ring is an annular solid, and its ring is embedded between upper bolster and the upper mold core, and the top of the bottom of last binder ring and said lower mold core ring is relative up and down; Between said upper bolster and the upper mold core above last binder ring sealing form one the 3rd air chamber, compressing with the air pressure of the 3rd air chamber and going up the binder ring; Said upper slitter is an annular solid, and its lower open mouth that is fixed in upper bolster is along last, and the top of the bottom of upper slitter and said binder ring down is relative up and down; The outer, bottom of said upper slitter is provided with the upper knife edge that cooperates with said blade down.
The further scheme of technique scheme is following:
In the such scheme, said upper mold core is made up of the patrix core body that is fixedly connected on the patrix core print seat on the upper bolster and is fixedly arranged on patrix core print seat bottom; Said lower mold core is made up of the counterdie core body that is fixedly connected on the counterdie core print seat on the die shoe and is fixedly arranged on counterdie core print seat top.
In the such scheme, offer steam vent on the top end face of said lower mold core and the bottom end face of upper mold core.
The operation principle of the utility model design is: the upper bolster of patrix is fixed on the Punching slider of punch press, and the die shoe of counterdie is fixed on the table top of punch press.During punching press; Placing the metal charge material on the end face of counterdie; When the Punching slider of punch press presses down when making upper die and lower die closed, upper slitter is engaged in die-cut circular down blank on the material material with following cutter, and the upper slitter continuation is pushing the binder ring downwards then; And enclose the outer Monday that last binder ring and the clamping of lower mold core ring on the blank, and last binder ring upwards moves back under the pushing of lower mold core ring; And the middle part that blank in said upper mold core and lower mold core clamping; Flange on the upper mold core stretches into the space of dodging that is used for the capel shaping on the counterdie; And lower mold core is moved back downwards under the pushing of upper mold core; Even enclose the outer Monday of the relative blank in middle part of blank and move down certain amplitude, thereby one time punching molded basic lid.
The utility model structural design is ingenious, can one time punching molded basic lid, under the certain situation of the downforce of punch press, promptly controlled the height parameter of the basic lid that stamps out through the air pressure inside size of controlling first air chamber, second air chamber and the 3rd air chamber.And a whole set of Mold Making is also comparatively convenient, and cost is lower.
