Abstract
The utility model provides a composite construction mechanical blade billet, which uses an alloy tool steel as a cutting edge steel, and uses a low-carbon steel as a cutting body steel, wherein the cutting edge steel is strip and arranged on the top of front cutting body, the back end of the cutting edge is combined with a cutting body steel, the combined surface is inclined surface, and the angel of the inclined surface and upper surface of the cutting body steel is a sharp angle. Compared with the prior arc, the service life is long, and the alloy tool steel material is saved.
Description
Technical field
The utility model relates to a kind of metal stock, relates in particular to a kind of composite construction mechanical bit blank.
Background technology
In the mechanical industry field, use each series hard alloy mechanical bit in a large number.In order to save production cost, each series hard alloy mechanical bit is general only to use a small amount of expensive alloy tool steel at knife edge part, then adopts comparatively cheap mild steel in the cutter hub part.Promptly with alloy tool steel as shear steel, with mild steel as the cutter hub steel.The version of all kinds of composite construction mechanical bits of present domestic prior art generally as shown in Figure 1, it constitutes by cutter hub steel 11, shear steel 12 are compound, shear steel 12 is positioned at the top front end of cutter hub steel 11, the faying face of the rear end of shear steel 12 and cutter hub steel 11 is an inclined-plane, and the upper surface of this inclined-plane and cutter hub steel intersects the obtuse angle.The top of shear steel 12 rear ends is acute angle in other words, and the bottom is the obtuse angle.Mechanical bit in use can wear and tear gradually and shorten, and in order to ensure the bond strength of composite construction mechanical bit, the general user will scrap this blade when using to the also surplus 5mm of the distance of the working face of shear steel and faying face.This composite construction mechanical bit of above-mentioned prior art also exists the service life of shear steel short, the learies of shear steel is big, the big inadequately problem of bond strength of cutter hub steel and shear steel, is unfavorable for saving, influences economic benefit of enterprises.And the basic structure of composite construction mechanical bit is by the blank decision that is used to make this blade, and the problem that the composite construction mechanical bit produces is the problem that exists of composite construction mechanical bit blank just.
Summary of the invention
The purpose of this utility model provides a kind of composite construction mechanical bit blank of new structure exactly in order to address the above problem.
The purpose of this utility model is achieved in that a kind of composite construction mechanical bit blank, be as shear steel with alloy tool steel, with the composite structural member of mild steel as the cutter hub steel, described blank is double-deck polylith composite structural member, lower floor is a big cutter hub steel, the upper strata is constituted by a shear steel and a cutter hub steel, the faying face of upper strata shear steel and upper strata cutter hub steel is an inclined-plane, the upper surface of this inclined-plane and upper strata cutter hub steel intersects acute angle, and driving fit links into an integrated entity between each piece cutter hub steel and the shear steel.
The angle of described acute angle is 30-60 °.
The angle of described acute angle is 45 °.
The utility model composite construction mechanical bit blank makes it compared with prior art owing to adopted above technical scheme, has following advantage and characteristics:
1, prolongs the service life by the mechanical bit of its making, improved the utilization rate of shear steel;
2, can save a large amount of alloy tool steel materials as shear steel;
3, the bond strength of cutter hub steel and shear steel is improved.

Fig. 2 is the structural representation of the utility model composite construction mechanical bit blank;
Fig. 3 is the structural representation of the mechanical bit made by blank shown in Figure 2;

The specific embodiment
Referring to Fig. 2, cooperate referring to Fig. 3, the utility model composite construction mechanical bit blank is as shear steel, with the composite structural member of mild steel as the cutter hub steel with alloy tool steel.Its structure as shown in Figure 2, the structure of the mechanical bit of being made by this blank is as shown in Figure 3.The utility model composite construction mechanical bit blank is double-deck polylith composite structural member, lower floor is a big cutter hub steel 31, the upper strata is constituted by a shear steel 32 and a cutter hub steel 33, upper strata shear steel 32 is an inclined-plane with the faying face of upper strata cutter hub steel 33, the upper surface of this inclined-plane and upper strata cutter hub steel intersects acute angle, the angle of this acute angle can be selected between 30-60 °, is preferably 45 °.
Referring to Fig. 4, Fig. 5, Fig. 4 is the structural representation of prior art composite construction mechanical bit blank when using life end point, and Fig. 5 is the structural representation of the utility model composite construction mechanical bit blank when using life end point.By Fig. 4, Fig. 5 as seen, the thickness of the shear steel that is comprised in two kinds of mechanical bits is 5mm, the inclined-plane, rear end and the cutter hub steel upper surface of prior art composite construction mechanical bit blank shear steel intersect 135 ° of obtuse angles, or inclined-plane, the rear end extended line of shear steel and the crossing acute angle at 45 of cutter hub steel upper surface; The inclined-plane, rear end of the utility model composite construction mechanical bit blank shear steel and cutter hub steel upper surface intersect acute angle at 45.But the amount of the shear steel that is comprised in two kinds of mechanical bits is the same.When mechanical bit use life end point, when promptly using to the also surplus 5mm of the distance of the working face of shear steel and faying face, prior art composite construction mechanical bit blank has shifted to an earlier date the distance of 5mm to life end point than the utility model composite construction mechanical bit blank, the amount of remaining shear steel also was that prior art composite construction mechanical bit blank is more than the utility model composite construction mechanical bit blank when two kinds of mechanical bits arrived life end point.This explanation, all kinds of composite construction mechanical bit blanks of under equal conditions making adopt structure of the present utility model to increase the service life, the alloy tool steel material of conserve expensive.As calculated, be that the angle of 70mm, faying face is 45 ° if shear steel thickness is 5mm, shear steel width, then adopt every blade of structure of the present utility model can save shear steel about 11%.Angle according to different shear steel thickness, width and faying face can obtain different reduction effects.
The utility model composite construction mechanical bit blank is when making, be at a certain angle in conjunction with as the upper strata with a shear steel (alloy tool steel) and a cutter hub steel (mild steel), be placed on the big cutter hub steel (mild steel), and guarantee the cleaning and the driving fit of each contact-making surface, with welding manner all faying faces are sealed then, at high temperature keep time enough,, three steel perfect adaptations are integral make again through mill milling.By changing the angle of upper strata cutter hub steel and shear steel faying face, can make mechanical bit blank with various bevel angles, be used to make mechanical bit with various bevel angles.
