Abstract
The utility model relates to a powder material pressing and molding module, which belongs to the technical field of a pressing module device. Friction material is the most important part of a brake sheet. The processing quality of the friction material directly influences the brake performance. The technology extensively adopted in the present production is that formula material powder (friction material) is mixed, the material powder is pressed into a material base (preliminary molding), and the material base and a steel plate are sintered. In the pressing process of the material powder, the air in a module cavity is discharged out of the module cavity through the clearance between a convex module and a concave module and the material powder is easy to adhere to the clearance and influences the matching quality of the convex module and the concave module. The technical scheme of the utility model is that the lower part of a guide concave module (1) is provided with a vent hole (3), a concave module (5) is arranged on a base plate (6), the material powder (4) and a convex module (2) are respectively arranged in the guide concave module (1) and the concave module (5). The utility model has the advantages of reasonable structural design and smart and novel design, avoids the sticking phenomenon of the material in the clearance of the convex module and the concave module and prolongs the service life of the module.
Description
Technical field
The utility model relates to diel device technique field, is a kind of dusty material press-moulding die more specifically.
Background technology
Friction material is the brake block most important parts, and its crudy directly influences braking quality.The technology that extensively adopts in producing at present is: formulation material powder (friction material) mixes---will expect that powder is pressed into material base (first one-step forming)---with material base and steel plate sinter molding together.In the compacting of material powder, the air in the die cavity goes out die cavity by interstitial row protruding, die, and the material powder is adhered in the gap, influences the punch-die fit quality; Can make material in mould upper surface deposition again, the pressing process that easily enters next piece material base makes the material base difficult quality guarantee.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of dusty material press-moulding die of design.Its technical scheme is: the bottom at the guiding die offers steam vent, and die is installed on the backing plate, is respectively arranged with material powder and punch in guiding die and die.The advantage of this utility model is: reasonable in design, and the novelty that is skillfully constructed has avoided material to attachment phenomenon protruding, the die gap, has improved die life; Improve the exhaust situation of material in forming process, improved product quality; Discharge gas and siphoned away, protected environment by the inlet scoop.
Description of drawings
This accompanying drawing is the utility model structural representation.In the accompanying drawing: 1, guiding die, 2, punch, 3, steam vent, 4, the material powder, 5, die, 6, backing plate.
The specific embodiment
Bottom at guiding die 1 offers steam vent 3, and die 5 is installed on the backing plate 6, is respectively arranged with material powder 4 and punch 2 in guiding die 1 and die 5.In the compacting of material powder 4, the air in the die cavity goes out die cavity by the interstitial row of punch 2, die 1 and 5, and the material powder is adhered in the gap, influences the punch-die fit quality; Can make material in mould upper surface deposition again, the pressing process that easily enters next piece material base makes the material base difficult quality guarantee.In view of preliminary shaping mould die adopts split-type structural, offer steam vent 3 in guiding die 1 bottom, make steam vent 3 ends towards the inlet scoop.So both made smooth and easy that the passing away of air becomes, expected simultaneously that powder can be sucked away more completely, avoided the deposition of material powder, kept clean environment at the mould upper surface.
Claims (1)
1. dusty material press-moulding die is characterized in that: the bottom at guiding die (1) offers steam vent (3), and die (5) is installed on the backing plate (6), is respectively arranged with to expect powder (4) and punch (2) in guiding die (1) and die (5).
