Abstract
The invention discloses a combined upper punch for a control panel powder metallurgy forming die, comprising three assemblies: an upper outer punch, an upper inner punch and a threaded rod, wherein the upper outer punch and the upper inner punch are connected through the threaded rod. The combined upper punch for the control panel powder metallurgy forming die solves the problem of the cracking generated in the forming process of the upper punch, thereby prolonging the service life of the die and reducing the production cost; moreover, the surface roughness of the upper punch is improved, thereby solving the problem that the die is stuck to the upper punch in the forming process, reducing the product cracking risk and lowering the risk that the die is damaged because of dual pressure. The combined upper punch for the control panel powder metallurgy forming die is suitable for serving as a powder metallurgy forming die.
Description
Technical field
The present invention relates to the machine die field, be specifically related to a kind of combination upper punch of control panel powder Metallurgy Forming tool.
Background technology
Because the shape of the part to be processed of the type is special, and density requirements and hardness require all very high, the powder metallurgy industry generally all adopts the design of integral type to this part forming mould design upper punch at present, be punched on this integral type in the forming process and easily locate to crack, thereby cause the mould breakage not use at the R angle of mould.This design is because material is general cold work die steel or alloy tool steel in addition, so after shaping a period of time, the roughness variation on upper punch surface, be easy in forming process, occur being stained with dashing, be in the knockout course of part to be processed, part to be processed is bonded at the problem that upper punch does not take off, thereby has the part quality risk of instability.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of control panel powder Metallurgy Forming tool, this invention has solved the cracking problem that is punched in forming process, and be stained with the risk of dashing in the reduction forming process, thereby prolong the service life of mould, reduce production costs, solve the destabilizing factor in producing.
For solving the problems of the technologies described above, reach above-mentioned technical purpose, the present invention adopts following technical scheme:
A kind of combination upper punch of control panel powder Metallurgy Forming tool comprises outwash, dashes in going up, three assemblies of screw rod, wherein, described go up to dash in outwash and described the going up be connected by described screw rod, formation makes up upper punch.
Preferably, the material of dashing in described upward outwash and described the going up is a cold work die steel.
Preferably, the hardness of described cold work die steel is between HRC58-HRC62.
Preferably, the material of dashing in described upward outwash and described the going up is an alloy tool steel.
Preferably, the hardness of described alloy tool steel is between HRC58-HRC62.
Preferably, to be coated with one deck HV0.05 hardness number be 3400 coating on the surface of described combination upper punch.
Preferably, the coating of described hardness is TiAlN coating.
Compared with prior art, the combination upper punch of control panel powder Metallurgy Forming tool of the present invention has following advantage:
1. combination upper punch of the present invention is greatly enhanced die life: the integral type upper punch generally is shaped 5K and just cracks with interior product, and after adopting the combination upper punch, probably between 6W-8W, be equivalent to improve die life about 16 times die life.
2. combination upper punch of the present invention, increased overlay coating, die life is probably between 15-18W, make improve 2-3 doubly the die life of stamping again, greatly reduce the quality risk in the shaping production process simultaneously, dash the crackle cause as being stained with of part to be processed, and being stained with to dash and causing two the pressure to cause the mould breakage of part to be processed.
Description of drawings
Fig. 1 is the structural representation of combination upper punch of the present invention.
Fig. 2 is the schematic diagram of the total assembling structure of mould of the present invention.
Number in the figure explanation: 1. go up outwash, dash in 2. going up, 3. screw rod, 4. former is 5. gone up stamping cover, 6. go up the outwash pressure pad, 7. dash for first time, 8. first time punching press pad, 9. second time punching press pad 10. descends stamping cover, 11. plug, 12. plug glands, 13. plug connectors, 14. combination upper punches.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
The structural representation of combination upper punch as shown in Figure 1, a kind of combination upper punch of control panel powder Metallurgy Forming tool comprises outwash 1, dashes 2 in going up, 3 three assemblies of screw rod, wherein, by screw rod 3 will go up outwash 1 and last in dash 2 and link together, constitute combination upper punch 14.
The schematic diagram of the total assembling structure of mould as shown in Figure 2, comprise former 4, last stamping cover 5, last outwash pressure pad 6, dash 7 first time, first time punching press pad 8, second time punching press pad 9, following stamping cover 10, plug 11, plug gland 12, plug connector 13 and combination upper punch 14, wherein, combination upper punch 14 and last stamping cover 5, it is in aggregates that last outwash pressure pad 6 connects combination, and first time towards 7, first time punching press pad 8 and second time punching press pad 9 are combined into an integral body, former 4 and following stamping cover 10, plug 11, the action of plug gland 12 and plug connector 13 is synchronous, and plug 11 can float, and makes powder be pressed into green compact in upper punch integral body and the following integral body of dashing at former 4 and 11 acting in conjunction powder of plug during shaping.
Because the density requirements height of the part to be processed that is shaped, on be punched in the progressive forming process wearing and tearing especially easily, because powder metallurgy dashes general cold work die steel or the alloy tool steel of adopting up and down, hardness is generally between HRC58-HRC62, the upper punch wearing and tearing cause surface roughness poor, cause production process unstable as be stained with dash etc. bad, then on the working face of combination upper punch, do the coating that surface treatment increases one deck high rigidity, through overtesting and production practical experience, preferably, selected TiAlN coating, about 3400 because the hardness of TiAlN coating can reach HV0.05, can allow the wearability on upper punch surface improve 2-3 doubly by overlay coating like this.
By combination upper punch of the present invention, and in conjunction with the total assembling structure acting in conjunction of above-mentioned mould, the shaping part to be processed, the life-span of mould has improved widely, the integral type upper punch generally is shaped 5K and just cracks with interior product, probably between 6W-8W, be equivalent to improve die life about 16 times die life after the employing combination upper punch;
By producing checking, improved 2-3 again doubly the die life of stamping behind the increase overlay coating, greatly reduce the quality risk in the shaping production process simultaneously, dash the crackle that causes, and product is stained with towards causing two the pressure to cause the mould breakage as being stained with of part to be processed.
