The above-mentioned raw material of being cut band steel 14 is that width is the flat cold-rolled sheet of 199mm after presorting bar; Become the steel band of 6 31.75mm width through the two side cut blade apparatus slitting itemizes of above-mentioned circle shear; Simultaneously both sides each produce the wide slitter edge silk of about 4.25mm, the slitter edge silk through the batch turning groove after coiler for trimmings below the entering.
In above-mentioned pair of side cut blade apparatus, the following slitter edge cutter 11 of cutter under the last slitter edge cutter 11 of upper slitter reaches ' the same long with cutter 12 and bottom knife 12 ' diameter respectively, this device can produce the slitter edge silk that is total to 8.5mm, causes cost to waste.
The utility model content
The purpose of the utility model is in order to solve the problem that prior art exists, not trimming device of a kind of circle shear slitting to be provided, and both sides need not sheared when this device can make the shearing of band steel itemize through changing blade structure, did not produce the slitter edge silk.
The purpose of the utility model realizes through following technical scheme:
A kind of circle shear slitting is trimming device not, comprises cutter under disk upper slitter and the disk, is cut the band steel and places under disk upper slitter and the disk between the cutter; Said disk upper slitter comprises: be fixed on several structures and measure-alike cutter on the upper slitter shaft sleeve; Closely install on the transmission side slitter edge cutter on fixing at the upper slitter shaft sleeve; Be respectively equipped with between last slitter edge cutter and an adjacent cutter and on the upper slitter shaft sleeve between per 2 cutters size all identical on rubber washer, cutter comprises under the said disk: be fixed on the following cutter shaft sleeve and quantity, structure and the size bottom knife identical with cutter; Closely install fixing following slitter edge cutter on the fore side at following cutter shaft sleeve; Between following slitter edge cutter and an adjacent bottom knife and on the following cutter shaft sleeve between per 2 bottom knife, be respectively equipped with all identical following rubber washer of size, it is characterized in that:
The diameter of said last slitter edge cutter and following slitter edge cutter is not run into the slitter edge passage respectively than the big 9-11mm of diameter of cutter and bottom knife.
The diameter with cutter and bottom knife is identical respectively for the outside dimension of said last rubber washer and following rubber washer.
Said upward slitter edge cutter reaches down, and the width of slitter edge cutter is 19mm.
The beneficial effect of the utility model:
The circle shear slitting of the utility model is trimming device not, and both sides need not sheared when band steel itemize was sheared, and did not produce the slitter edge silk, needs in the existing band steel shearing technique to shear both sides and produce the wasting problem of waste silk thereby solved, and has improved the product lumber recovery; Owing to do not cut edge in this device both sides, also therefore reduced the power consumption of device, also reduced the workload that the slitter edge crimping machine is safeguarded simultaneously, reduced production cost.
Be above-mentioned purpose, design feature and the effect that further specifies the utility model, below will combine accompanying drawing that the utility model is elaborated.
Description of drawings
Fig. 1 is the two side cut blade apparatus figure of existing circle shear;
Fig. 2 is the circle shear slitting trimming device figure not of the utility model.
The specific embodiment
Be elaborated below in conjunction with the accompanying drawing of embodiment the specific embodiment to the utility model.
The structural representation that the circle shear slitting device of the utility model is not cut edge is referring to Fig. 2, and is as shown in the figure, this device comprise cutter 20 under disk upper slitter 20 and the disk ', by cut the band steel 24 place cutter 20 under disk upper slitter 20 and the disk ' between.Disk upper slitter 20 comprises: be fixed on several structures and measure-alike cutter 22 (present embodiment is 3 cutters 22) on the upper slitter shaft sleeve 25; Slitter edge cutter 21 on the upper slitter shaft sleeve 25 nearly device transmission sides fixing one; Be respectively equipped with between last slitter edge cutter 21 and an adjacent cutter and on the upper slitter shaft sleeve 25 between per 2 cutters size all identical on rubber washer 23.Cutter 20 under the disk ' structure and the symmetrical configuration of disk upper slitter 20, it comprises: be fixed on the identical bottom knife 22 of a following cutter shaft sleeve 25 ' go up and quantity, structure and size and cutter 22 '; Following cutter shaft sleeve 25 ' closely install a fixing following slitter edge cutter 21 on the fore side '; Following slitter edge cutter 21 ' with an adjacent bottom knife between and following cutter shaft sleeve 25 between per 2 bottom knife ' on be respectively equipped with all identical following rubber washer 23 of size '.
