Below in conjunction with concrete accompanying drawing detailed description is carried out in the realization of the utility model.
Shown in Fig. 1～2, a preferred embodiment that provides for the utility model embodiment.
This circle shear mechanism 1 is used for metal material is sheared, so that the requirement of the wide of the material after shearing regulation, in the present embodiment; This circle shear mechanism 1 is used for band steel raw material 3 is sheared; Certainly, also be used for other metal material is sheared, not merely be limited to band steel 32.This circle shear mechanism 1 comprises a pair of cutter 11 that is provided with in opposite directions, the distance that this is certain to formation between the cutter 11, and this distance can require be provided with according to reality; Like this; When band steel raw material 3 these cutters 11 of process, this is sheared the dual-side of band steel raw material 3 respectively cutter 11, cuts off the slitter edge 31 of band steel raw material 3 dual-sides; Thereby make band steel raw material 3 form the band steel 32 of fixed width; This cutter 11 comprises upper tool pan 111 and following cutterhead 112, and upper tool pan 111 goes to upper and lower dislocation and plumbness setting each other with following cutterhead 112, like this; Have end play between upper tool pan 111 after being provided with and the following cutterhead 112, and have lap in vertical direction between upper tool pan 111 and the following cutterhead 112.
In the reality, the user utilizes in the process that 1 pair in above-mentioned circle shear mechanism band steel 32 shears, and the phenomenon of cutter 11 frequent spring cuttves takes place through regular meeting; Perhaps be no more than 100 ton hours, the problem of cutter 11 serious wear often take place, like this at output; In process of production, change with regard to the cutter 11 that carries out that must be frequent, in order to solve these problems of exist actually; The upper tool pan 111 of cutter 11 all has the cutting edge that is used for shear band steel raw material 3 with following cutterhead 112 in the present embodiment, and the hardness of cutting edge is arranged between HRC53～HRC56, like this; Find that in actual production process cutter 11 is in shear history, the cutter phenomenon can not jump; And have only processing capacity to reach more than 1500 tons, the phenomenon of serious wear just can appear in cutter 11, improves the shearing ton amount of cutter 11 greatly; Avoid the phenomenon of frequent change cutter 11 in process of production, and practiced thrift cost greatly, boost productivity.
, when shearing inclined to one side softwood matter steel grade, occur shearing constantly or the relatively poor phenomenon of shearing quality, for fear of this circle shear mechanism 1 like the IF steel; Its metal flow better performances, thus be easy to take place to shear continuous phenomenon, even and cut short; Its quality of edges is also relatively poor, and burr is obvious, and the end play between the upper tool pan 111 of the cutter 11 of the circle shear mechanism 1 of present embodiment and the following cutterhead 112 is 1/11～1/8 of band steel 32 thickness; And increase the lap of cutter 11 upper tool pans 111 and play cutterhead 112, make lap between upper tool pan 111 and the play cutterhead 112 be with steel 32 thickness 1/5～2/5 between, like this; In practical operation, when circle shear is sheared steel, continuous phenomenon can not appear shearing; And the quality of the steel after shearing is better, the tangible phenomenon of burr can not occur.When shearing inclined to one side softwood matter metal material, the lap between upper tool pan and the play cutterhead is for being with 1/2～2/3 of steel 32 thickness.
In practical operation, for production efficiency is provided, the user can have more the thickness and the material of band steel 32; The upper tool pan 111 and the end play of following cutterhead 112, the tables of data of lap have been formulated; Like this, the individual can be directly according to this table in practical operation; The band steel 32 of corresponding processing is regulated the upper tool pan 111 and the following cutterhead 112 of circle shear mechanism 1.
Carry out in the process of cutter 11 of circle shear, at band steel raw material 3 in order to make that cutterhead 112 can be to 3 certain supporting roles of band steel raw material, in the present embodiment down; In the same cutter 11; Following cutterhead 112 is positioned at the inboard of upper tool pan 111, the setting because upper tool pan 111 and following cutterhead 112 stagger each other, and they have certain overlapping relation; And with respect to the center line of circle shear mechanism 1, following cutterhead 112 is positioned at the inboard of upper tool pan 111.
In the present embodiment, have the shearing station in the circle shear mechanism 1, band steel raw material 3 is sheared on this shearing station; Thereby form the band steel 32 of fixed width, in order to guarantee to shear with steel raw material 3 cutter 11 that gets in the circle shear mechanism 1 that can be the level of state, this circle shear mechanism 1 also has upper gasket 12 and lower gasket 13; This upper gasket 12 be arranged on shear station directly over; Place the inboard of upper tool pan 111, and upper gasket 12 can be connected on the upper surface of band steel raw material 3, this lower gasket 13 place shear station under; Place down the inboard of cutterhead 112; And can be connected on the lower surface of band steel raw material 3, thereby the clamp position that band steel raw material 3 is in upper gasket 12 and lower gasket 13 gets in the cutter 11 to be sheared.
In order to support the band steel raw material 3 that to shear; This circle shear mechanism 1 also has plate face carrying roller 14; This plate face carrying roller 14 be positioned at shear station under; It is arranged on down between the cutterhead 112, and is connected on the lower surface of band steel raw material 3, and its lower surface to band steel raw material 3 plays certain supporting role.
When being with steel raw material 3 in the process of shearing, the phenomenon of arch can appear in band steel raw material 3, for fear of being with 3 arches of steel raw material; This circle shear mechanism 1 also has plate face pressure roller 15; This plate face pressure roller 15 be positioned at shear station directly over, and be arranged between the upper tool pan 111, and be connected on the upper surface of band steel raw material 3; The downward active force that it can give band steel raw material 3 upper surfaces prevents to be with steel raw material 3 doming effect to occur going up.
In the present embodiment, upper tool pan 111 and following cutterhead 112 are in to band steel 32 continuous shear histories, and upper tool pan 111 can be because continuous grinding with following cutterhead 112; Its diameter can diminish, and the diameter of upper gasket 12 and lower gasket 13 is constant, like this; Along with upper tool pan 111, following constantly the dwindling of diameter of cutterhead 112, the original lower surfaces of the band steel sheared 32 can be scratched by cutterhead 112 down, for fear of scuffing; In the present embodiment; The diameter of the upper gasket 12 in the circle shear mechanism 1 is than the little 2mm of diameter of upper tool pan 111, and the diameter of lower gasket 13 is than the big 2mm of diameter of following cutterhead 112, like this; In actual production, the phenomenon that scratches with cutterhead 112 under steel raw material 3 quilts can not appear again.
In the present embodiment, the diameter of upper tool pan 111 and following cutterhead 112 all is 350mm.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
