Abstract
The utility model newly discloses a kind of hinge die with edge-folded, belongs to mould applications, comprises punch, cushion block, backing plate, die, bolt, rotating the needle, baffle plate; It is characterized in that being added with rotating the needle in patrix die cavity, rotating the needle totally 4, be uniformly distributed, coordinate with rotating the needle interporal lacuna, punch side adds overhead gage, utilize bolt and punch fastening.It has the simple feature of structure, improves mould utilization factor, reduces production cost, ensure that Production requirement.
Description
Technical field
The utility model relates to mould applications, especially a kind of hinge die with edge-folded.
Background technology
Wiring dit is the one of bending die typical structure, is usually used in the part forming such as hinge, hinge.Due to long-term production in enormous quantities, add the friction between blank and punch die cavity face, add the cause that T8 material itself wears no resistance, cause the wearing and tearing of punch die cavity, cut, have impact on hinge quality and dimensional requirement.
Summary of the invention
In order to solve, die punch die cavity is easy to wear, the problem of cut, the utility model proposes a kind of hinge die with edge-folded, and it has the simple feature of structure, improves mould utilization factor, reduces production cost, ensure that Production requirement.
The technical scheme that the utility model has solved technical problem employing is: this mould comprises punch, cushion block, backing plate, die, bolt, rotating the needle, baffle plate; Be added with rotating the needle in described patrix die cavity, rotating the needle totally 4, be uniformly distributed, coordinate with rotating the needle interporal lacuna, punch side adds overhead gage, utilize bolt and punch fastening.
Described rotating the needle adopts Cr12 material, and barrier material is δ 5/Q235A.
The beneficial effects of the utility model are: be proven, and use good, solve the poor product quality problem because die wear causes, significantly improve mould utilization factor, reduce production cost, ensure that Production requirement.
Accompanying drawing explanation
Fig. 1 improves the structural representation of front hinge wiring dit;
The top view of Fig. 2 Fig. 1
The punch structure schematic diagram of Fig. 3 mould;
1. punch, 2. cushion block, 3. backing plate, 4. die, 5. screw, 6. rotating the needle in figure.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing: as shown in Figure 1, this mould comprises punch, cushion block, backing plate, die, bolt, rotating the needle, baffle plate; Add rotating the needle in described patrix die cavity, rotating the needle totally 4, be uniformly distributed, coordinate with rotating the needle interporal lacuna, punch side adds overhead gage, utilize bolt and punch fastening.
For reducing mould production cost, improve die life, we have carried out process modification on the former basis of mould, are specially:
(1) mould is delivered to heat treatment department and carry out annealing in process.After annealing in process completes, through measuring cavity dimension.
(2) in patrix die cavity, rotating the needle is added, to reach dimensional requirement.As shown in Figure 2.During work, Points replacing surfaces, utilizes rotating the needle rolling to carry out crimping.Rotating the needle totally 4, is uniformly distributed, coordinates with rotating the needle interporal lacuna.Rotating the needle adopts the good Cr12 material of wearability, heat treatment 58 ~ 62HRC.When wearing and tearing appear in mould again, only need change rotating the needle, just can continue to use.
(3) time for preventing rotating the needle from working screw out punch, damage, add overhead gage in punch side, barrier material is δ 5/Q235A, utilize bolt and punch fastening.
Mould after improvement is proven, and uses good, solves the poor product quality problem because die wear causes, significantly improve mould utilization factor, reduce production cost, ensure that Production requirement.
Claims (2)
1. a hinge die with edge-folded, comprises punch, cushion block, backing plate, die, bolt, rotating the needle, baffle plate; It is characterized in that being added with rotating the needle in patrix die cavity, rotating the needle totally 4, be uniformly distributed, coordinate with rotating the needle interporal lacuna, punch side adds overhead gage, utilize bolt and punch fastening.
2. a kind of hinge die with edge-folded according to claim 1, it is characterized in that rotating the needle adopts Cr12 material, barrier material is δ 5/Q235A.
