Abstract
The utility model discloses a cold extrusion punch, which is characterized by comprising a punch body (1) and a punch seat (2) arranged at one end of the punch body (1), a cutting edge (3) is arranged at the other end of the punch body (1), and a metal ceramic coating layer is coated on the cutting edge (3). The cold extrusion punch is designed for cold extrusion forming research and used as a forward extrusion, reverse extrusion and forming punch in cold extrusion forming, and the service life of the cold extrusion punch is 4-5 times of that of an existing cold extrusion punch, so that waste in the cold extrusion forming process is reduced and cost is saved.
Description
Technical field
The utility model relates to a kind of drift, what be specifically related to is a kind of cold extrusion drift.
Background technology
Existing cold extrusion drift is not wear-resisting, easily sliding injury, service life short, easily broken, local buildup, the problem long-term existence such as pull, thereby lowered the quality of the drift of colding pressing.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of wear-resisting, cold extrusion drift that can increase the service life.
To achieve these goals, the utility model is to realize by the following technical solutions:
The utility model comprises the drift body and is arranged on the punch holder of drift body one end that the other end of drift body is provided with cutting edge, is coated with metal-cermic coating on cutting edge.This coating is high temperature resistant, hardness is big, wearability is strong, affinity is good, coating still keeps good binding with blanking punch, can not come off, not easy to wear, make the drift average life span improve 4～5 times, saved the maintenance cost of mould transposing drift, reduced trouble and workload that the staff changes drift, guarantee the normal steady production of forcing press, improved the production efficiency of lead frame again.
The material that above-mentioned cold extrusion drift adopts is a high-speed steel.
The thickness of above-mentioned metal-cermic coating is 1～4 μ m.Can not influence the dimensional accuracy of cold extrusion drift, lead frame.
Above-mentioned metal-cermic coating is a nitrogen titanizing aluminized coating.
The utility model uses as just crowded, anti-crowded, moulding drift in cold extrusion forming at cold extrusion shaped research and design; Be 4～5 times of existing cold extrusion drift service life, thus reduced process waste, saved cost.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
The utility model comprises drift body 1 and is arranged on the punch holder 2 of drift body 1 left end that the right-hand member of drift body 1 is provided with cutting edge 3.
The utility model cold extrusion drift adopts the enterprises standard than GB strictness, detects to adopt to meet the industry standard detection mode.This product has solved short problem of cold extrusion manufacturing enterprise drift life-span substantially, has played the effect for its minimizing process waste, saving cost relatively.
The material that the utility model cold extrusion drift adopts is a high-speed steel, adopts high-speed steel (SKH51; ASP23) moulding is through after the mirror finish, on cutting edge 3 or all applied a metal-cermic coating.This coating is high temperature resistant, hardness is big, wearability is strong, affinity is good, and coating is participated in the moulding of materials and parts directly, under the HI high impact friction condition, coating still keeps good binding with drift, can not come off, not easy to wear, make the drift average life span improve 4～5 times, saved the maintenance cost of mould transposing drift, reduced trouble and workload that the staff changes drift, guaranteed the normal steady production of forcing press, the production efficiency that has improved again.
In the present embodiment, metal-cermic coating is a nitrogen titanizing aluminized coating.
The thickness of metal-cermic coating is 1～4 μ m.Can not influence the dimensional accuracy of cold extrusion drift.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
