Abstract
The utility model discloses a finished hole discharge guide box with straightening function, which comprises a head area of a discharge guide box, a front trumpet area, a rear straight channel area, and an opening on the lower portion of the straight channel area. The discharge guide box is characterized in that the discharge guide box is integrally in a rectangular shape, the head area is cut to be sharp through an upper and a lower circular arcs, a round hole penetrates through the inner by a left and a right central lines, the round hole is between the head area and the rear straight channel area, the trumpet front trumpet area is in a trumpet shape, and the rear straight channel area is provided with the opening on the lower portion of a straight channel, whose length is slightly shorter than the straight channel area. The discharge guide box not only has the function of protecting the guide discharge, but also can straighten big bends in any direction generated when a minitype rolling mill rolls high alloy specific steel rods with high temperature, and has simple and firm structure, strong integration, high shock resistance performance and low manufacturing cost.
Description
Technical field
The utility model relates to the rolling a kind of apparatus of metal material, specifically, is a kind of finished product hole discharging guide and guard box with aligning effect, is used for producing on the bar milk high alloy special steel bar.
Background technology
In the rolling field of metal material, discharging guide and guard box is widely used.But, the common discharging guide and guards that is used for bar milk is the frock that belongs to the guide class, only plays the guiding stocking to lead out track, not aligning effect, and bar milk mainly uses on the less high alloy special steel of production lot now, and in the majority with the round steel bar; Because after mostly annealing, the high alloy special steel has the mechanical performance higher than general ordinary steel, so when the aligning of bar, comparatively serious to the impact and the wearing and tearing of equipment for straightening.If during rolling high alloy special steel, can utilize the discharging guide and guards while hot the finished product stocking to be carried out certain aligning, will reduce the later aligning number of times of finished product bar so, alleviate the workload of aligning operation, finally reduce the wearing and tearing of equipment for straightening, increased its service life.At present, still do not have a kind of simple in structurely, cheap for manufacturing cost, have the finished product hole discharging guide and guards of certain straightening function.
The utility model content
Technical problem to be solved in the utility model is: a kind of finished product hole discharging guide and guard box with aligning effect is provided, have the double action of guide and guard and aligning concurrently, when can be used for aligning bar milk production high alloy special steel bar, big the bending on any direction that hot rolled circular steel produces.
To achieve these goals, the technical solution adopted in the utility model is: the finished product hole discharging guide and guard box with aligning effect, the header area that comprises discharging guide and guard box, anterior loudspeaker oral region, straight way district, rear portion, straight way district lower openings, it is characterized in that: discharging guide and guard box is whole to be cuboid, header area is cut to the tip shape mutually by circular arc up and down, inner left and right sides center line is through with round hole, the circle hole is distinguished from the head between the rear portion straight way district, is trumpet-shaped anterior loudspeaker oral region, and a straight way district lower openings that slightly is shorter than the straight way section length is arranged in rear portion straight way district.
In the technique scheme, the shape of described straight way district lower openings be on the opening under wide and the opening wide ratio be 1: 2.5～3 the wide diagonal cut joint of suitable for reading narrow end opening.
As the preferred embodiment of technique scheme, the length＞400mm in straight way district, described rear portion (c), internal diameter size is than supporting rolling round steel specification 〉=4～8mm.
After adopting technique scheme, after the finished product red heat round steel of finish to gauge comes out from roll finished product hole, enter the loudspeaker oral region, be imported into again in the straight way in straight way district by the header area of finished product hole discharging guide and guard box.Because of the rolling supporting finished product hole discharging guide and guard box of each size round steel, its straight way internal diameter is more bigger than corresponding specification, thus the guide and guard box can the round steel finished product is waltzed through, finish oriented tasks, again can be after the red heat round steel passes the straight way district with certain-length, with big bending straightening.The straight way district lower openings of guide and guard box adopts up-small and down-big diagonal cut joint design, and the one, avoid the excessive clamping aligning face that has reduced bar of opening, the 2nd, help successfully dropping of oxide skin in the bar aligning process.
The beneficial effects of the utility model are: can not only play the function of protection guiding discharging, and in the time of can also be with bar milk hot rolling high alloy special steel bar, big curved aligning the on any direction of generation; this device globality is strong; simple in structure firm, the shock resistance height, cheap for manufacturing cost.

A. header area among the figure; B. anterior loudspeaker oral region; C. straight way district; D. straight way district lower openings; E. wide on the opening; F. wide under the opening.
The specific embodiment
Further the utility model is illustrated below in conjunction with drawings and Examples.
Referring to Fig. 1～2, finished product hole discharging guide and guard box with aligning effect, the header area a that comprises discharging guide and guard box, anterior loudspeaker oral region b, straight way district, rear portion c, straight way district lower openings d, it is characterized in that: discharging guide and guard box integral body is cuboid, header area a is cut to the tip shape mutually by circular arc up and down, inner left and right sides center line is through with round hole, a is distinguished from the head between the rear portion straight way district c in the circle hole, is trumpet-shaped anterior loudspeaker oral region b, at rear portion straight way district c the one straight way district lower openings d that slightly is shorter than the straight way section length is arranged.The shape of described straight way district lower openings d be on the opening under wide e and the opening ratio of wide f be 1: 2.5～3 the wide diagonal cut joint of suitable for reading narrow end opening.As preferred embodiment, length＞400mm of described rear portion straight way district c, internal diameter size is than supporting rolling round steel specification 〉=4～8mm.
The W6Mo5Cr4V2Co high alloy tool steel of concrete rolling Φ 16～Φ 30mm specification, the straight way internal diameter of supporting finished product hole discharging guide and guard box its straight way district c is Φ 18～Φ 34mm, length 420mm, wide e is 5～10mm on the opening of straight way district lower openings d, wide e is 10～15mm under the opening.During work, the finished product of guide and guard box header area a being aimed at roll portals, and chucking is fixed on the mill stand; After the red heat round steel finished product of finish to gauge came out from roll finished product hole, the header area a from finished product hole discharging guide and guard box entered loudspeaker oral region b earlier, is imported in the straight way of straight way district c again; After the round steel finished product of red heat passed the straight way district, macrobending was in any direction all aligned, and was imported into delivery track then, changed next procedure over to.In the aligning process, the red heat round steel is walked the oxide skin that drops and is successfully dropped out from straight way district lower openings d.
