Abstract
The utility model discloses a disk-shaped rolling blade, which comprises a steel knife body and a hard-alloy knife edge, wherein the steel knife body and the hard-alloy knife edge are connected through a weld. The utility model improves the disk-shaped rolling blade made of an integrated hard alloy into a structure formed by together welding the hard-alloy knife edge and the steel knife body, prolongs the service life of the disk-shaped rolling blade, saves the hard-alloy material and greatly lowers the cost.
Description
Technical field
The utility model relates to a kind of rolling cut to be cut, particularly a kind of disc rolling blade.
Background technology
Roll-turning steel plate shearing machine is mainly used in crosscut (crop end, cut size) and rip cutting (cutting edge and subdivision) steel plate, usually be combined into and shear unit and be arranged on the production line, be a kind of complex structure, technical difficulty is big, automatization level is high and complete auxiliaries is more tinplate, in thick iron plate, silicon steel sheet shearing equipment.Rolling cut cut with traditional Heavy Plate Production line on the oblique sword of shearing equipment cut to compare and have shear steel board size precision height, energy consumption is little, the long and high characteristics of output of life-span.In order to guarantee to shear the quality of steel plate, the disc rolling blade must have high hardness and wearability.
At present, make the disc rolling blade generally with two types of materials.One type is Cr
12, Cr
12Alloy tool steels such as MoV, another kind of type is a carbide alloy.With service life of the disc rolling blade of carbide alloy manufacturing be disc rolling blade service life made from alloy tool steel 20-50 doubly, be example with the tungsten carbide, its material price is 500 yuan/kilogram, cost is higher.The tungsten carbide disks shape rolling blade of an external diameter 172.8mm, the heavy 2.69kg of material, Master Cost is 1346 yuan.
Summary of the invention
The utility model provides a kind of long service life and the low disc rolling blade of cost for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of disc rolling blade, comprise steel cutter hub and carbide alloy system blade, and described steel cutter hub is connected by weld seam with carbide alloy system blade.
The utility model can also adopt following technical scheme: described weld seam is the copper alloy weld seam.
Described carbide alloy system blade is made by tungsten carbide.
Advantage and the good effect that the utlity model has are: the disc rolling blade that whole hard alloy is made is improved to the structure that is welded together by carbide alloy system blade and steel cutter hub, improved the service life of disc rolling blade, save Hardmetal materials, greatly reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, cutter hub, 2, blade, 3, weld seam.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1, a kind of disc rolling blade of the utility model, comprise cutter hub 1 and blade 2, cutter hub 1 is a steelwork, and blade 2 is made by carbide alloy, and the steel knife body is connected by weld seam 3 with carbide-tipped cutter bit.In the present embodiment, carbide alloy is a tungsten carbide.Because copper alloy has higher mechanical property, anti-attrition performance and corrosion resistance, nonmagnetic, so cutter hub 1 and blade 2 preferably adopt the copper alloy welding wire welding.
Adopting the external diameter of said structure is the disc rolling blade of 172.8mm, and disc rolling blade material cost only is 205 yuan.Compare with the disc rolling blade of tungsten carbide manufacturing, but surplus every disc rolling blade economical with materials expense 1100 yuan.Compare basic identical with the disc rolling blade of tungsten carbide manufacturing the service life of disc rolling blade.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
