Abstract
The utility model discloses a washer blanking die set which overcomes the shortcomings that according to existing dies in the prior art, a male die and a female die capable of being used simultaneously for punching inner bores do not exist, and cost is increased due to the fact that an upper die plate and a lower die plate are arranged. The washer blanking die set is simple in structure and capable of manufacturing a washer in a one-step blanking mode. The washer blanking die set is particularly suitable for manufacturing washers which are nonstandard parts in a small-lot mode. The washer blanking die set comprises an upper die and a lower die. The lower die comprises a lower female die. A lower male die is fixedly assembled on the lower end portion of the inner side of the lower female die. The upper die is formed by a male die portion and a female die portion. The male die portion of the upper die is matched with the lower female die of the lower die. The female die portion of the upper die is matched with the lower male die of the lower die. A feeding groove is formed in the middle of a side face of the lower female die. The feeding groove passes through an inner cavity of the lower female die transversely. The washer blanking die set has the advantages of being high in flexibility, quite short in production cycle, simple in structure and low in cost.
Description
Technical field
The utility model belongs to technical field of mold, is specifically related to a kind of packing ring blanking die.
Background technology
Existing packing ring generally all adopts standard component, the standard component packing ring then adopts precision die to produce in enormous quantities, but it is not standard component that the needed packing ring of some products is arranged, and this will enterprise settle a dispute by the parties concerned themselves, if manufacture and design a cover precision die this moment earlier yet, obviously do not meet economic principle, if and employing pincers worker single-piece is made, seem time-consuming not only but also require great effort, specification quality all is difficult to guarantee, therefore adopting and make a secondary simple and easy rather than complicated mould should be a kind of selection preferably.
For example China Patent No. 01246784.7, and name is called the utility model patent of " pieces of sheet diel ", proposes a kind of pieces of sheet diel.It includes bolster and guide pillar, the upper punch that below cope match-plate pattern, removably connects, and a following punch die removably connects above the lower bolster.This patent one be lack can be simultaneously towards the punch-die of endoporus, the 2nd, set up bolster, this is both inapplicable also impracticable for punched washer.
Summary of the invention
The utility model technical issues that need to address are, the mould that overcomes prior art lack can be simultaneously towards the punch-die of endoporus, being provided with bolster again increases the defective of cost, provide a kind of simple in structure, can one time stamping-out just make the mould of packing ring, this mould is particularly useful for the packing ring of non-standard component and small lot to be made.
The purpose of this utility model is achieved by following technical proposals: a kind of packing ring blanking die, comprise upper die and lower die, and it is characterized in that counterdie comprises lower cavity die, the bottom of lower cavity die inboard fixedly is equipped with lower punch; Patrix is made of a punch-die, and the punch of patrix cooperates with the lower cavity die of counterdie, and the die of patrix cooperates with the lower punch of counterdie, and the middle part, side of lower cavity die is provided with feed well one, and feed well traverses the inner chamber of lower cavity die.
Concrete application process is: 1, lower punch is cooperated fixing with the bottom of lower cavity die; 2, the feed well of tablet from the lower cavity die side injected, make its front end be against the bottom of feed well; 3, punch-die is combined on the lower cavity die of counterdie; 4, press with press, perhaps beat and to go out required packing ring by stamping-out with hammer.
As preferably, the downside of feed well constitutes the cutting edge of lower cavity die.
As preferably, be evenly equipped with 3 guiding pins between patrix and the lower cavity die, the upper end of guiding pin is fixed on patrix, and the lower end of guiding pin and the guide pillar pin-and-hole of lower cavity die upper surface are slidingly matched.
As preferably, be with back-moving spring outside the guiding pin.
As preferably, fixedly connected by screw thread with the bottom of lower punch in the bottom of lower cavity die inboard.
As preferably, the patrix centre is provided with through hole, and through hole is communicated with the die hole of patrix.
The beneficial effects of the utility model are:
1. mobility strong, applicability is strong;
2. fabrication cycle is short especially;
3. simple in structure, easy to operate;
4. with low cost.
Description of drawings
Fig. 1 is that a kind of embodiment of the utility model assembles schematic diagram;
Fig. 2 is the utility model embodiment lower cavity die structural representation;
Fig. 3 is the utility model embodiment punch-die structural representation.
Among the figure, lower cavity die 1; Feed well 11; Lower punch 2; Punch-die 3; Punch 31; Die 32; Through hole 33.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
Embodiment: shown in Fig. 1～3, a kind of packing ring blanking die comprises upper die and lower die, and counterdie comprises lower cavity die 1, and the bottom of lower cavity die 1 inboard fixedly is equipped with lower punch 2; Patrix is made of a punch-die 3, the punch 31 of patrix cooperates with the lower cavity die 1 of counterdie, the die 32 of patrix cooperates with the lower punch 2 of counterdie, the middle part, side of lower cavity die 1 is provided with feed well 11 one, feed well 11 traverses the inner chamber of lower cavity die 1, the downside of feed well 11 constitutes the cutting edge of lower cavity die 1, and the width of feed well is 1.1mm, and this width is the most suitable to the plate of 0.5-1mm.
Be evenly equipped with 3 guiding pins between patrix and the lower cavity die 1, the upper end of guiding pin is fixed on patrix, and the lower end of guiding pin and the guide pillar pin-and-hole of lower cavity die upper surface are slidingly matched, and guiding pin outside is with back-moving spring.
Fixedly connected by screw thread with the bottom of lower punch in the bottom of lower cavity die inboard.
The patrix centre is provided with through hole 33, and through hole is communicated with the die hole of patrix, and this through hole is used for the waste material of die head circle endoporus and discharges.
Concrete assembling process is: 1, lower punch 2 and the bottom of lower cavity die 1 are cooperated fixing by being threaded; 2, the feed well 11 of tablet from lower cavity die 1 side injected, make its front end be against the bottom of feed well 11; 3, the pin that will lead press fit over the lower surface of punch-die 3, and back-moving spring is enclosed within on the guide finger post; 4, punch-die 3 is combined on the lower cavity die of counterdie, insert in the guide pin hole of lower cavity die the lower end of the pin that will lead simultaneously; 4, press with press, perhaps beat and to go out required packing ring by stamping-out with hammer.
The utility model is particularly useful for the mould of the various nonstandard packing rings of punching out and uses, has short, the simple in structure and with low cost especially advantage of mobility strong, fabrication cycle, if those skilled in the art does simple the modification or replacement to the foregoing invention content, such change can not think to break away from scope of the present utility model, and all will be included within the scope of claim of the present utility model the apparent modification of those skilled in the art like this.
