Abstract
The utility model discloses a two counter bore carbide product forming die structures, including core bar, upper punch subassembly, down stroke subassembly and bed die, the upper punch subassembly includes outer upper punch and interior upper punch, the down stroke subassembly includes outer down stroke and interior down stroke, is equipped with the fitting surface that the core bar of being convenient for is connected on interior upper punch and the interior down stroke, in outer upper punch is located outside the upper punch, and in outer down stroke is located outside the down stroke, upper punch subassembly and down stroke subassembly are connected to the core bar, and make constitution product shaping region between upper punch subassembly and the down stroke subassembly, and upper punch subassembly and down stroke subassembly still are equipped with outward the bed die including both parcels. The utility model discloses utilize the structural adjustment proportion of feeding of inside and outside upper punch and inside and outside down stroke and the pressure size of press forming to reach two smooth fashioned purposes of counter bore, the design of upper punch and interior down stroke structure in the while is favorable to avoiding the tradition to concentrate the position to appear crackle and severe deformation's problem easily in the density of punching press product.
Description
Technical field
The utility model relates to carbide alloy field, particularly a kind of two counterbore hart metal product forming die structure.
Background technology
Carbide alloy is suppressed by powder metallurgical technique by the hard compounds of refractory metal and binding metal, sintered a kind of alloy material made.Carbide alloy has that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, and particularly its high rigidity and wearability, even if also substantially remain unchanged at the temperature of 500 DEG C, still have very high hardness 1000 DEG C time.
The mould of traditional two counterbore products is upper undershoot structures, and product concentrates position easily to occur crackle and gross distortion in the pressed density of counterbore base.
Utility model content
Based on this, for the problems referred to above, be necessary to propose a kind of two counterbore hart metal product forming die structure, when this structure solves punching press, product counterbore base pressed density is too concentrated, and the problem of crackle and gross distortion easily appears in product.
The technical solution of the utility model is: a kind of two counterbore hart metal product forming die structure, comprise core bar, upper punch assembly, undershoot assembly and former, described upper punch assembly comprises outer upper punch and interior upper punch, described undershoot assembly comprises outer undershoot and interior undershoot, interior upper punch with interior under rush to the mating surface being provided with and being convenient to core bar and being connected, outer upper punch is located at outside interior upper punch, outer undershoot is located at outside interior undershoot, described core bar connects upper punch assembly and undershoot assembly, and make to form formed product region between upper punch assembly and undershoot assembly, upper punch assembly and undershoot assembly are also provided with outward and both are wrapped in interior former.
In the utility model, the contact surface of upper punch and interior undershoot is platform structure, at forming area, powdery product is housed, pressed compact is formed by the punching press of mould, two upper undershoot structure of the present utility model, can flexible modulation counterbore position charging ratio, thus the problem that bottom two counterbore holes of products, pressed density is too high.
Preferably, described former is ring channel structures.
Preferably, described former periphery is provided with the chuck of interference fit with it.
The beneficial effects of the utility model are: the structure improving mould, and the structure of upper punch and interior undershoot regulates charge and compressing pressure size in utilizing, thus reach two counterbore object shaping smoothly, the design of upper punch and interior undershoot structure simultaneously, is conducive to avoiding tradition to concentrate position easily to occur the problem of crackle and gross distortion in the density of stamping products.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure, 11-former, the outer upper punch of 12-, the outer undershoot of 13-, upper punch in 14-, undershoot in 15-, 16-core bar, 17-forming area.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Embodiment:
A kind of two counterbore hart metal product forming die structure, as shown in Figure 1, comprise core bar 16, upper punch assembly, undershoot assembly and former 11, described upper punch assembly comprises outer upper punch 12 and interior upper punch 14, described undershoot assembly comprises outer undershoot 13 and interior undershoot 15, interior upper punch 14 is provided with interior undershoot 15 mating surface be convenient to core bar 16 and be connected, outer upper punch 12 is located at outside interior upper punch 14, outer undershoot 13 is located at outside interior undershoot 15, described core bar 16 connects upper punch assembly and undershoot assembly, and make to form formed product region 17 between upper punch assembly and undershoot assembly, upper punch assembly and undershoot assembly are also provided with outward and both are wrapped in interior former 11.
In the utility model, the contact surface of upper punch 14 and interior undershoot 15 is platform structure, is placed with powdery product at punching press gap area 17, and in when filling with substance utilizes, upper punch 14 and interior undershoot 15 flexible modulation charging ratio, meet product punch forming.
The above embodiment only have expressed detailed description of the invention of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
