Abstract
The utility model discloses a pig fodder forming annular mould. A feeding opening (2), a primary forming hole (3) and a pressure reducing hole (4) which are communicated in sequence are formed between the inner wall and the outer wall of an annular mould body of the annular mould. The length-diameter ratio of the primary forming hole is 7.5-8.5. The hole diameter ratio of the pressure reducing hole to the primary forming hole is between 1.15 and 1.25. The length-diameter ratio of the pressure reducing hole is 3-5. Cone transition of 60-120 degrees is formed between the primary forming hole and the pressure reducing hole. The feeding opening is a cone opening of 35-45 degrees. The compression amount and the expanding amount of fodder can be controlled accurately through the annular mould. The utility model further discloses an expanding drill for machining forming holes. The expanding drill is used for hole expanding of the primary forming hole (3) and machining of the cone face of the feeding opening (2).
Description
Technical field
The present invention relates to a kind of pig feed mould, 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.
While extruding from forming hole due to feed granules, have expansion to a certain degree, especially piglet feed too extruding in forming hole of pig feed, can make feed temperature raise more, heat-sensitive substance meeting coking in formula, cause feed granules hardening, be unfavorable for eating, existing pig feed shaping mould by the two poles of the earth or multi-stage stairs hole to the feed release of reducing pressure, reduce the decrement of feed, in order to avoid feed is subject to undue extruding, utility model patent 201220176634.9 discloses a kind of piglet feed forming ring mold of level Four stepped hole, this utility model comprises die body, inwall one end of die body offers blanking port, die body outer wall one end offers the multi-step pressure reduction moulding stepped hole being communicated with blanking port, multi-step pressure reduction moulding stepped hole comprises the elementary forming hole that aperture increases successively, one-level vent, second depressurized hole and three grades of vents.
Existing pig feed shaping mould has to a certain degree solved the problem of pig feed hardening by the two poles of the earth or multi-stage stairs hole to the feed method discharging that reduces pressure, but because the decrement to pig feed and swell increment are not accurately controlled, the feed of producing is sometimes too bulk, shape irregularity is high containing powder rate.
Summary of the invention
Technical problem to be solved by this invention is to provide the pig feed forming ring mold of a kind of simple in structure, decrement and swell increment precise control, and the pig feed of production is bulk regular, low containing powder rate; The present invention also provides the reamer in a kind of machine-shaping hole.
Technical scheme of the present invention is: a kind of pig feed 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, elementary forming hole, vent, the draw ratio of described elementary forming hole is between 7.5～8.5, the aperture ratio of vent and elementary forming hole is between 1.15～1.25, the draw ratio of vent is between 3～5, between elementary forming hole and vent, be the circular cone transition of 60 °～120 °, charging aperture is the cone ports of 35 °～45 °.
The draw ratio of described elementary forming hole preferably 8.
The aperture ratio of described vent and elementary forming hole preferably 1.2.
The draw ratio of described vent preferably 4.
Circular cone transition between described elementary forming hole and vent is the circular cone transition of 90 ° preferably.
Described charging aperture is the cone ports of 40 ° preferably.
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 35 °～45 °, and drill bit is for the reaming of elementary forming hole, and taper countersink is for the processing of charging aperture.
Pig feed forming ring mold of the present invention is controlled at the draw ratio of elementary forming hole between 7.5～8.5, the aperture ratio of vent and elementary forming hole is controlled between 1.15～1.25, the draw ratio of vent is controlled between 3～5, compared with prior art simple in structure, can accurately control decrement and the swell increment of feed, the feed of producing is bulk regular, low containing powder rate; 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 elementary forming hole reaming, has improved working (machining) efficiency, and can ensure the axiality of charging aperture and elementary forming hole.
