Abstract
The utility model discloses a brake calibre guide pin cold upsetting mould used for cold upsetting, moulding and processing a brake calibre guide pin. The cold upsetting mould comprises a head mould part and a rod mould part which are moulded in an integrated manner, the head mould part is internally provided with a head cavity used for moulding a calibre guide pin head, and the rod mould part is internally provided with a rod cavity used for moulding a calibre guide pin rod part. The brake calibre guide pin cold upsetting mould can effectively control the straightness and the verticality of a calibre guide pin and guarantee the product quality in the fastener blank cold upsetting moulding process.
Description
Technical field
The utility model relates to a kind of cold-heading mould, specifically relates to the cold pier mould of a kind of brake clamp guide finger.
Background technology
The clamp guide finger is the important securing member of braking automobile clamp, requirement has very high linearity and perpendicularity, producing brake clamp guide finger adopts the cold-heading mould to carry out processing and forming usually, but, in the prior art, the cold upsetting forming die of clamp guide finger is generally split type mould, namely comprises head mold and bar portion mould.This split type cold-heading mould exists product linearity and perpendicularity problem of unstable behind the cold-heading molding, and the linearity of clamp guide finger product and perpendicularity are difficult to control, has influenced the quality of clamp guide finger product.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes the cold pier mould of a kind of brake clamp guide finger, in fastener blank cold-heading molding process, can effectively control linearity and the perpendicularity of clamp guide finger, guarantee product quality.
The technical solution of the utility model is achieved in that
The cold pier mould of a kind of brake clamp guide finger, be used for cold-heading molding processing brake clamp guide finger, described cold-heading mould comprises head mold portion and the bar portion mold of integrated molding, be provided with the head cavity for moulding clamp guide finger head in the described head mold portion, be provided with the bar cavities for moulding clamp guiding pin rod portion in the described bar portion mold.
As further improvement of the utility model, described head mold portion comprises die sleeve and core rod, and described die sleeve cover is fixed in outside the described core rod, forms described head cavity in the described core rod, and described core rod extends axially in the described bar portion mold.
As further improvement of the utility model, the surface of described head cavity and described bar cavities is through the burnishing surface behind the polishing grinding.
The beneficial effects of the utility model are: the utility model provides a kind of brake clamp guide finger cold pier mould, be used for cold-heading molding processing brake clamp guide finger, split type cold-heading mould compared to existing technology, the utility model is designed to head mold portion and the bar portion mold of integrated molding, form monoblock type cold-heading mould, thereby can avoid split type mould cold-heading forming process instability, have the problem of linearity and perpendicularity.In addition, handle the formation burnishing surface by the surface of head cavity and bar cavities being carried out polishing technology, can further improve the smoothness of clamp guide finger product behind the cold-heading molding, make the product behind the cold-heading molding be not easy to produce burr, and can reduce burr to the damage of monoblock type mould, improve the life-span of monoblock type mould.
Description of drawings
Fig. 1 is the cold pier mould structure of the utility model brake clamp guide finger schematic diagram.
By reference to the accompanying drawings, make the following instructions:
1---head mold portion 2---bar portion mold
11---head cavity 21---bar cavities
12---die sleeve 13---core rod
The specific embodiment
As shown in Figure 1, the cold pier mould of a kind of brake clamp guide finger, be used for cold-heading molding processing brake clamp guide finger, described cold-heading mould comprises head mold portion 1 and the bar portion mold 2 of integrated molding, be provided with the head cavity 11 for moulding clamp guide finger head in the described head mold portion, be provided with the bar cavities 21 for the bar portion of moulding clamp guide finger in the described bar portion mold.The quality that the linearity of brake clamp guide finger and perpendicularity have directly influenced this product, split type relatively cold-heading mould, the utility model head mold portion and bar portion mold integrated molding, the monoblock type mould that forms, can effectively control linearity and perpendicularity that the cold-heading of brake clamp guide finger adds man-hour, guarantee the quality of product.
Preferably, described head mold portion comprises die sleeve 12 and core rod 13, and described die sleeve cover is fixed in outside the described core rod, forms described head cavity in the described core rod, and described core rod extends axially in the described bar portion mold.According to the needs of cold-heading processing, core rod can adopt the bigger material of relative die sleeve hardness, to satisfy the cold-heading molding needs of clamp guide finger head.
Preferably, the surface of described head cavity and described bar cavities is through the burnishing surface behind the polishing grinding.Adopt polishing technology that head cavity and bar cavities are carried out polishing, can further improve the smoothness of clamp guide finger product behind the cold-heading molding, make the product behind the cold-heading molding be not easy to produce burr, and can reduce burr to the damage of monoblock type mould, improve the service life of monoblock type mould, save production cost.
Above embodiment is with reference to accompanying drawing, and preferred embodiment of the present utility model is elaborated.Those skilled in the art is by carrying out modification or the change on the various forms to above-described embodiment, but do not deviate under the situation of essence of the present utility model, all drops within the protection domain of the present utility model.
