Abstract
The utility model discloses a chicken fodder forming annular mold. According to the annular mold, by means of a first-level forming hole (3), a second-level forming hole (4), a third-level forming hole (5) and the length-diameter ratio design of the first-level forming hole (3), the second-level forming hole (4) and the third-level forming hole (5), after the first-level forming hole (3) of the annular mold is abraded, the length-diameter ratio of the forming holes is controlled to be within a stable range through action of the second-level forming hole (4), after the second-level forming hole (4) of the annular mold is abraded, the length-diameter ratio of the forming holes is controlled to be within a stable range through action of the third-level forming hole (5), and the service life of the annular mold is greatly prolonged. The utility model further discloses a reamer used for machining the forming holes, wherein the reamer is used for machining a counterbore of the first-level forming hole (3) and the conical face of a feed port (2).
Description
Technical field
The present invention relates to a kind of chicken feedstuff forming die, the invention still further relates to the reamer for machine-shaping hole.
Background technology
Fodder forming ring mold is the ring mould for feed moulding, comprise annular die body and be arranged on the multiple forming holes on annular die body, when use, pressure roller is at ring mold cavity rotary squeezing feed, extrude in feed link overmolding hole, then be cut into the feed granules of certain length by the cutting knife that is arranged on ring mould outside.
Owing to containing the grits such as more corn in chicken feed granules, the forming hole wearing and tearing of ring mould are very fast, after forming hole wearing and tearing, the draw ratio of shaped hole declines, be that compression ratio declines, result causes feed to contain the rising of powder rate, and the feed of production is defective, existing chicken feed ring mould is not long service life, in order to improve ring mould service life, existing method is confined to improve the hardness aspect of ring mould, complex process more, cost is higher, and effect is bad.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of chicken fodder forming ring mold of long service life; The present invention also provides the reamer in a kind of machine-shaping hole.
Technical scheme of the present invention is: a kind of chicken fodder forming ring mold, comprise annular die body, between the inwall of described annular die body and outer wall, offer the charging aperture being communicated with successively, one-level forming hole, secondary forming hole, three grades of forming holes, described charging aperture is the cone ports of 60 °～70 °, described secondary forming hole diameter is 1.05 times～1.15 times of one-level forming hole diameter, three grades of forming hole diameters are 1.05 times～1.15 times of secondary forming hole diameter, the length of one-level forming hole is 9.5 times～10.5 times of its diameter, the overall length of secondary forming hole and one-level forming hole is 9.5 times～10.5 times of secondary forming hole diameter, three grades of forming holes, the overall length of secondary forming hole and one-level forming hole is 9.5 times～10.5 times of three grades of forming hole diameters.
As improvement of the present invention, described charging aperture is the cone ports of 65 °.
As improvement of the present invention, described secondary forming hole diameter is 1.1 times of one-level forming hole diameter, three grades of forming hole diameters are 1.1 times of secondary forming hole diameter, the length of one-level forming hole is 10 times of its diameter, the overall length of secondary forming hole and one-level forming hole is 10 times of secondary forming hole diameter, and the overall length of three grades of forming holes, secondary forming hole and one-level forming holes is 10 times of three grades of forming hole diameters.
The reamer in machine-shaping of the present invention hole comprises drill bit and drillstock, also has a taper countersink between drill bit and drillstock, and the conical surface of taper countersink is the taper seat of 60 °～70 °, and drill bit is for the reaming of one-level forming hole, and taper countersink is for the processing of charging aperture.
Chicken fodder forming ring mold of the present invention is by one-level, secondary, three grades of forming holes and draw ratio design thereof, after the one-level forming hole wearing and tearing of ring mould, by the effect of secondary forming hole, be that compression ratio is controlled in stable scope by the draw ratio of forming hole, after the secondary forming hole wearing and tearing of ring mould, by the effect of three grades of forming holes, be that compression ratio continues to be controlled in stable scope by the draw ratio of forming hole, large leap ahead in service life of ring mould; The reamer in machine-shaping of the present invention hole increases a taper countersink between drill bit and drillstock, does not need to change cutter and just can realize the processing of charging aperture after the reaming of one-level forming hole, has improved working (machining) efficiency, and can ensure the axiality of charging aperture and one-level forming hole.
