Abstract
The invention discloses an anti-adhesion punch for powder molding, which is characterized in that small air vents are distributed on the punch perpendicularly and evenly, a ventilating pipe is arranged at each of the air vents in a matching mode, and ventilating pipes are directly connected with a peripheral equipment air compressor through an air separating joint. When the anti-adhesion punch for powder molding works, air films can be prevented from being formed between the punch and powder, the adhesion of the punch to the powder is effectively prevented, and the quality of punch stamping powder molding product surface is not affected simultaneously.
Description
Technical field
The present invention relates to powder former technology, be specially a kind of powder moulding anti drift.
Background technology
Punch forming be a kind of can also be a kind of processing method of rapid shaping with the technology of powder straight forming through various moulds, in manufacture field, developed rapidly.At present prevent that in punching course the method for adhesion from having three kinds: the one, through changing the material composition, in raw material, add the method that prevents the adhesion composition.This method need change proportioning raw materials, not only influences product quality easily, and has increased the cost that manufactures a product; The 2nd, change the surface quality of stamping machine drift, make the method for drift contact surface adhesion material.This method need adopt special process that punch head surface is handled when the processing drift; Make drift form the adhesion surface, thereby increased the manufacturing cost and the maintenance cost of stamping machine, warp actual use after a while simultaneously; Also can drift anti surface abrasion be fallen; Not only improved its use cost, and service life is not long, result of use is successively decreased; The 3rd, smear anti liquid at the drift contact surface.This method need smeared anti liquid before each punching press, not only also can the anti liquid of smearing be pressed in the shaped article during punching press, influence product quality, and technological operation bothers, and had increased workman's manipulation strength, also had unsafe factor.
Summary of the invention
To the deficiency of prior art, the technical problem that quasi-solution of the present invention is determined is that a kind of powder moulding anti drift is provided; This drift can prevent in the powder moulding punching course, drift adhesion material, and simple in structure; Be easy to install, reduce cost, reduce labor strength.
The technical scheme that the present invention solve the technical problem is; Design a kind of powder moulding anti drift; It is characterized in that vertically being uniformly distributed with on this drift and have spilehole; And all mate a breather pipe be installed at each spilehole place, and said breather pipe directly links to each other with the ancillary equipment air compressor machine through dividing a gas joint.
Compared with prior art, powder moulding anti drift of the present invention mainly is on drift, to have opened spilehole, and at the spilehole place breather pipe is installed; Form air film between drift when making work and the powder, can prevent drift and powder adhesion effectively, do not influence the surface quality of drift punching press powder shaped article simultaneously; Have simple in structure; Be easy to installation and maintenance, energy-conserving and environment-protective, advantage such as reduce cost.
Description of drawings
Fig. 1 is the main TV structure sketch map of a kind of embodiment of powder moulding anti drift of the present invention;
Fig. 2 is the plan structure sketch map of a kind of embodiment of powder moulding anti drift of the present invention.
The specific embodiment:
Further narrate the present invention below in conjunction with embodiment and accompanying drawing thereof.
The powder moulding anti drift of the present invention's design (is called for short drift; Referring to Fig. 1,2); It is characterized in that vertically being uniformly distributed with on this drift 3 and have spilehole (or gas hole) 5; And all mate a breather pipe 4 be installed at each spilehole 5 place, and said breather pipe 4 directly links to each other with ancillary equipment air compressor machine (not drawing among the figure) through dividing a gas joint.The diameter of said spilehole 5 and quantity are decided according to the technological requirement of shape, size and the gas film pressure of drift.
The diameter of the said spilehole 5 of drift of the present invention is 2-4mm.The diameter of spilehole 5 is excessive, is unfavorable for forming air film, also can increase the power and the operating cost of air compressor machine; And the diameter of spilehole 5 is too small, can obviously increase the local pressure of gas hole outlet, destroys the surface quality of powder shaped article.
Centre distance between the adjacent spilehole 5 of drift of the present invention is 60-70mm.Centre distance is excessive, can reduce the quantity of gas hole, is unfavorable for the even distribution of air, forms stable air film; Centre distance is too small, then can increase the power of air compressor machine, reduces the intensity of drift.
The diameter of the said breather pipe 4 of drift of the present invention is 2-4mm, with said spilehole 5 diameters coupling, is convenient to install.
The drift of the embodiment of the invention is square, the spilehole 5 that to have 68 diameters be 3mm, and the centre distance between the adjacent spilehole 5 is 65mm, the breather pipe 4 that it is 3mm that each spilehole 5 place all is equipped with a diameter.During work, the air pressure in the breather pipe 4 is 0.6-0.8MPa.
The operation principle and the process of drift of the present invention are: behind 1 li filling powder of mold cavity, under the drive of stamping machine hydraulic cylinder 2, drift 3 moves downward, the punching press forming material powder; When drift 3 and mold cavity 1 were closed, described breather pipe 4 began to blow to mold cavity 1 in through the spilehole 5 that is uniformly distributed with, and made formation layer of even air film between lower surface and the powder of drift 3.This air film can prevent drift 3 and powder adhesion effectively, does not influence punching press powder compacting surface quality of products simultaneously again; After the formed product, breather pipe 4 continues to blow, and keeps air pressure in certain process time of 0.75MPa, and then, under the drive of stamping machine hydraulic cylinder 2, drift 3 moves upward, and breather pipe 4 is stopped the supple of gas or steam, and the completion drift separates with shaped article.
Anti drift of the present invention is applicable to the anti technology of general powder through the compression forming product.The present invention efficiently solves the adhesion problems in the powder-product punch forming process, and simple in structure, is easy to industrializing implementation, and has been successfully applied on the production line of abatvoix moulding.
The present invention does not address part and is applicable to prior art.
