Abstract
The invention discloses a method for machining a forming hole of an annular feed forming mould and a reamer. The method comprises the steps that a center hole is drilled at the center of an inner-wall forming hole of an annular mould body through a center drill firstly; secondly, the forming hole is drilled roughly in the position of the center hole from the inner wall of the annular mould body to the outer wall of the annular mould body through a twist drill; thirdly, the hole is reamed through the forming hole reamer, chamfering is conducted on a hole opening, burrs of the hole opening are removed, and the machined forming hole is smooth, clean and standard. According to the forming hole reamer, a conical-surface counter bit (12) is additionally arranged between a drill bit (11) and a drill handle (13), after the forming hole is reamed, chamfering and burr removal can be conducted on the hole opening without the need for cutter replacement, and therefore machining efficiency is improved.
Description
Technical field
The present invention relates to a kind of processing method of fodder forming ring mold forming hole, the invention still further relates to the forming hole 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, during use, pressure roller is at ring mold cavity rotary squeezing feed, extrude in feed link overmolding hole, then by the cutting knife that is arranged on ring mould outside, be cut into the feed granules of certain length.
The processing of existing forming hole is all to be punched to annular die body inwall by the external wall of circular die, because annular die body inwall is ring surface, forming hole drills through rear aperture dimidiation, drill bit cannot machining, aperture can only be squeezed, and causes aperture coarse, shape irregularity, the burr in aperture is also difficult to remove, and has increased the resistance of feed moulding, affects the outward appearance of feed.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing method of forming hole, and the forming hole processing is bright and clean regular; The present invention also provides a kind of forming hole reamer.
The processing method of a kind of fodder forming ring mold forming hole of the present invention comprises the steps: first to use the center drill centers of centre drill at annular die body inwall forming hole, then with fluted drill, in the position of centre bore, by annular die body inwall, to the external wall of circular die, slightly bore forming hole, use again the reaming of forming hole reamer, and at orifice chamfer, remove aperture burr.
Forming hole reamer of the present invention comprises drill bit and drillstock, between drill bit and drillstock, also has a taper countersink, the conical surface of taper countersink is the taper seat of 90 ° preferably, and drill bit is for the reaming of forming hole, and taper countersink is for chamfering and the removing aperture burr in forming hole aperture.
The processing method of fodder forming ring mold forming hole of the present invention adopts the method machine-shaping hole to the external wall punching of circular die by annular die body inwall, and compared with the conventional method, the forming hole processing is bright and clean regular, and the resistance of feed moulding is little; Forming hole reamer of the present invention increases a taper countersink between drill bit and drillstock, and forming hole does not need to change cutter after reaming just can realize orifice chamfer, removes aperture burr, has improved working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the structure chart of fodder forming ring mold.
Fig. 2 is the structure chart of forming hole reamer of the present invention.
In figure, each Reference numeral is: 1, annular die body; 2, forming hole; 11, drill bit; 12, drillstock; 13, taper countersink.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described, but embodiment is not construed as limiting the invention.
Referring to Fig. 1, the processing method of a kind of fodder forming ring mold forming hole of the present invention comprises the steps: first to use the center drill centers of centre drill at annular die body 1 inwall forming hole 2, then with fluted drill, in the position of centre bore, by annular die body 1 inwall, to annular die body 1 outer wall, slightly bore forming hole 2, use again the reaming of forming hole reamer, and at orifice chamfer, remove aperture burr.
Referring to Fig. 2, forming hole reamer of the present invention comprises drill bit 11 and drillstock 12, between drill bit 11 and drillstock 12, also has a taper countersink 13, the conical surface of taper countersink 13 is taper seats of 90 °, drill bit 11 is for the reaming of forming hole 2, and taper countersink 13 is for orifice chamfer and the removing aperture burr of forming hole 2.
