Description

A kind of burr remover of cast block
Technical field
The utility model relates to cast member burr remover, is specifically related to a kind of burr remover of cast block.
Background technology
By the cast member of conventional cast die casting and molding, conventionally can produce overlap and burr at the spue line place of cast member at present; Its reason is casting mould in long-time use procedure, and die joint moving, cover half clashes into and is very easy to wearing and tearing through continuous folding, and the wearing and tearing of die joint make after cast member casting, and the spue line place of cast member can produce overlap and the burr of land area.Overlap and the burr at the spue line place of cast member not only affect the processing of cast member, and have a strong impact on product appearance quality.
As shown in Figure 5, Figure 6, existing a kind of cast block, the lateral surface of this cylinder block 21 is provided with some radiating fins 23, and the spue line 22 of cylinder block is arranged on cylinder block middle part.When after cylinder block 21 castings, cylinder block spue line 22 places can produce overlap and burr conventionally; And overlap and burr are distributed between radiating fin 23.
Conventionally adopt the instruments such as file manually to remove for overlap on cast member and burr at present, but manually remove overlap and burr is not only wasted time and energy, and remove overlap and burr quality not good.In order to solve the deficiency of manual removal overlap and burr, conventionally adopt at present the mode of punch die punching press to replace manual removal overlap and burr.The mode of punch die punching press is on punch die, to design punching hole according to product profile; Cast member is fixed on punch press, utilizes the drift of punch press to drive punch die, and utilize punching hole lower port as cutting edge, the overlap on product and burr to be machined away.
Because cast block lateral surface is provided with some radiating fins, and the overlap of cast block and burr are distributed between radiating fin; If adopt mode deflashing and the burr of existing punch die punching press, the frock clamp of its countercylinder body and installation accuracy have very high requirement, cause the radiating fin that damages punch die and the cylinder block destruction that is stamped otherwise be easy to depart from (punching hole and the cylinder block of punch die depart from) because of cylinder block installation site.On the other hand, because overlap and the burr of cylinder block are distributed in cylinder block middle part, while adopting the deflashing of existing punch die impact style and burr; Overlap and burr are easily bent, and are difficult to thoroughly remove overlap and burr.
Utility model content
The purpose of this utility model is that the punch die impact style in order to overcome in existing employing technology is removed overlap and the burr in cast block, not only easily cause the radiating fin of punch die and the cylinder block destruction that is stamped, and be difficult to thoroughly remove the problem of overlap and burr; Provide a kind of and not only can thoroughly remove overlap and the burr on cylinder block, and can guarantee the not burr remover of impaired cast block of cylinder block and punch die.
The technical solution of the utility model is:
