Abstract
The invention relates to a punching shear mechanical cutter blade, which is characterized in that a cutting edge is made of high-alloy steel 1, and a cutter body is made of low-alloy steel 2. The punching shear mechanical cutter blade composited by the two kinds of alloy steel not only saves steel blanks of the high-alloy steel for the punching shear mechanical cutter blade, but also is suitable for a normal drilling process when a positioning hole 3 is processed.
Description
Technical field:
The present invention relates to punching shear mechanical cutter blade.
Background technology:
At present, known punching shear mechanical cutter blade is to be made by single steel alloy, and promptly blade and cutter hub are all used with a kind of steel alloy integral body and made.
Because the working position of punching shear mechanical cutter blade is a blade, and common blade hardness is between HIC55-62, so blade must use high-alloy steel, cause cutter hub also to use high-alloy steel. with the blade and the cutter hub ratio of effective use is 8% to 92% and opinion, and then the high-alloy steel that uses of this 92% cutter hub can be considered a kind of waste.
In addition, must be drilled with some locating holes on the cutter hub of punching shear mechanical cutter blade,, then can change apart from precision at the heat treatment metapore if before heat treatment, hole; If boring after heat treatment, then the hardness of the hardness of high-alloy steel cutter hub and high-alloy steel blade is consistent and be not suitable for common bore process.
Summary of the invention:
In order to overcome that known punching shear mechanical cutter blade is made by single steel alloy and the problem that forms, the present invention is compound and make punching shear mechanical cutter blade with two steel alloys.
The technical solution adopted in the present invention is: utilize the high-alloy steel hardening heat principle close with the low-alloy steel normalizing temperature to handle the Technology for Heating Processing of compound two kinds of steel alloys well. by to the mode of dissimilar alloy steels, under the state of HTHP and oxygen-free seal, the blade of high-alloy steel and the cutter hub of low-alloy steel are composited with composite casting or location welding.
The invention has the beneficial effects as follows: use the cost blank of saving punching shear mechanical cutter blade with low-alloy steel because of cutter hub, still use 8% high-alloy steel and discuss with blade, cutter hub and blade compound tense composite surface increase by 7% high-alloy steel, thereby save 85% high-alloy steel as cutter hub. because the employed high-alloy steel material of punching shear mechanical cutter blade is that the rare metal of country is (as tungsten, molybdenum, chromium, vanadium etc.), so the present invention is useful to saving the national strategy goods and materials. in addition, because of using low-alloy steel reality with blade heat treatment in the lump the time, cutter hub is normalizing, be suitable for common bore process again, thereby guarantee the precision of locating hole.
Description of drawings:
The invention will be further described to the present invention and embodiment below in conjunction with accompanying drawing.
Fig. 1 and Fig. 3 are front view of the present invention, and wherein 1 is the locating hole distance.
Fig. 2 is an A-A cutaway view of the present invention, and wherein, 1 is high-alloy steel, and 2 is low-alloy steel, and 3 is locating hole.
Fig. 4 is a B-B cutaway view of the present invention, and wherein, 1 is high-alloy steel, and 2 is low-alloy steel, and 3 is locating hole.
The specific embodiment:
The present invention is composited the blade of high-alloy steel 1 and the cutter hub of low-alloy steel 2 under the state of HTHP and oxygen-free seal by to the mode of dissimilar alloy steels with composite casting or location welding.
In Fig. 1 was extremely embodiment illustrated in fig. 4, locating hole 3 was positioned at the cutter hub of low-alloy steel 2.
In embodiment illustrated in fig. 2, the blade of high-alloy steel 1 is compound in the cutter hub of low-alloy steel 2, and its recombination site is the side up and down of cutter hub.
In the embodiment shown in fig. 4, the blade of high-alloy steel 1 is compound in the cutter hub of low-alloy steel 2, and its recombination site is the positive antiplane of cutter hub.
Claims (3)
1. punching shear mechanical cutter blade, it is characterized in that: blade and cutter hub are composited by dissimilar alloy steels.
2. punching shear mechanical cutter blade according to claim 1 is characterized in that: the high-alloy steel blade is compound on the low-alloy steel cutter hub, and its recombination site is the side up and down of cutter hub.
