Abstract
The utility model belongs to structural improvement of shearing knives for numerical control hot-rolled steel bar straightening flying shears, and particularly relates to an improved shearing knife for a numerical control hot-rolled steel bar straightening flying shear. The improved shearing knife comprises an upper shearing blade and a lower shearing blade which are provided with mounting holes, the cross sections of the upper shearing blade and the lower shearing blade are parallelogram double-edge blades with the same sizes, the length of a long edge of a parallelogram is 101mm, and the distance between each cutting edge of the upper and lower shearing blades and the center line of each mounting hole 3 is 59mm. The improved shearing knife is of a symmetrical double-edge blade structure, the use ratio of the flying shear can be increased, materials for manufacturing the shearing knife are saved, two sides of a knife face can be sufficiently used, the number of prepared shearing knives of the flying shear can be decreased, and occupied capital for equipment maintenance spare parts is reduced.
Description
Technical field
The utility model belongs to the improvement of numerical control hot-rolled steel bar straightening flying shearing machine shear knife structure, particularly a kind of improved numerical control hot-rolled steel bar straightening flying shearing machine shear knife.
Background technology
GT8/16 numerical control hot-rolled steel bar straightening flying shearing machine cutting knife is asymmetric, and the blade of cutter has only been made the single face of shear knife workpiece geometric surface.In the whole process of production and application, can not take full advantage of other geometric surface of shear knife workpiece.Therefore the waste of shear knife workpiece material is larger, and flying shearing machine shear knife preparation quantity is many, and plant maintenance spare part occupied fund is large, the effect extreme difference.
Summary of the invention
The purpose of this utility model is to provide a kind of improved numerical control hot-rolled steel bar straightening flying shearing machine shear knife, its structure is symmetrical double-edged razor blade, can improve flying shearing machine shear knife utilization rate, save the material of making shear knife, and the two sides of knife face can take full advantage of, can reduce the quantity that the flying shearing machine shear knife is prepared, reduce the occupied fund of plant maintenance spare part.
The purpose of this utility model is achieved in that a kind of improved numerical control hot-rolled steel bar straightening flying shearing machine shear knife, comprise upper shear-blade and lower shear blade with installing hole, the shape of cross section of upper shear-blade and lower shear blade is the parallelogram double-edged razor blade that size equates, wherein the length on the long limit of parallelogram is 101mm, and upper and lower shear-blade cutting edge to the distance of installing hole center line is 59mm.
The utility model is with the double-edged razor blade that is shaped as the equal parallelogram symmetry of size of upper and lower shearing sheet design, two faces of blade can take full advantage of, improved the utilization rate of flying shearing machine shear knives, saved the material of making shear knife, and reduced aborning the quantity that the flying shearing machine shear knife is prepared, reduced the occupied fund of plant maintenance spare part.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described, Fig. 1 is cross-sectional TV structure schematic diagram of the present utility model.
The specific embodiment
A kind of improved numerical control hot-rolled steel bar straightening flying shearing machine shear knife, as shown in Figure 1, comprise upper shear-blade and lower shear blade with installing hole 3, the shape of cross section of upper shear-blade 1 and lower shear blade 2 is the parallelogram double-edged razor blade that size equates, wherein the length on the long limit of parallelogram is 101mm, and upper and lower shear-blade 1,2 cutting edges to the distance of installing hole 3 center lines are 59mm.
Claims (1)
1. improved numerical control hot-rolled steel bar straightening flying shearing machine shear knife, comprise have installing hole upper shear-blade and the lower shear blade of (3), it is characterized in that: the shape of cross section of upper shear-blade (1) and lower shear blade (2) is the parallelogram double-edged razor blade that size equates, wherein the length on the long limit of parallelogram is 101mm, and upper and lower shear-blade (1,2) cutting edge to the distance of installing hole (3) center line is 59mm.
