Abstract
The utility model provides a mechanical blade dimmer composite construction billet which is a double-layer multi-piece composite construction, wherein the lower layer is a big cutting body steel, the upper layer consists of a cutting edge steel and two cutting body steels, a cutting edge is provided in the middle of the two circumference, the two cutting body steels are symmetrically equipped on the two sides of the cutting edge, and the cutting body steel is closed with the cutting edge steel. The utility model can produce two blade billets at one rolling, thereby saving steel and reducing cost. The utility model can be used to make a plurality of billets of mechanical blades whose cutting edges are very narrow, and roll the cutter blank of mechanical blade whose cutting edges are very narrow.
Description
Technical field
The utility model relates to a kind of composition metal blank, relates in particular to a kind of mechanical bit binary composite construction blank.
Background technology
In the mechanical industry field, use all kinds of alloy tool steel mechanical bits in a large number.In order to save production cost, all kinds of alloy tool steel mechanical bits are 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.Be used to make the blank of mechanical bit, by shear steel with the cutter hub steel is compound constitutes, the composite construction form of the at present domestic all kinds of blanks that are used to make mechanical bit as shown in Figure 1.It is that a shear steel 11 (alloy tool steel) and a cutter hub steel 12 (mild steel) are placed on the big cutter hub steel 13 (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, again through mill milling, three blocks of steel are combined into one make.The problem that this structure exists is, rolling each time can only production a slice cutter blank, thereby the edge of a knife allowance of each blade is bigger, the production cost height, steel utilization ratio is low; In addition, for requiring the narrow especially mechanical bit of shear steel, corresponding blank is difficult to compound.
Summary of the invention
The purpose of this utility model provides a kind of mechanical bit binary composite construction 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 mechanical bit binary composite construction 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 two blocks of cutter hub steel, wherein, in the middle of a shear steel is arranged on, two blocks of cutter hub steel are symmetricly set on the both sides of a shear steel, and driving fit links into an integrated entity between each piece cutter hub steel and the shear steel.
A described shear steel that is arranged on the centre, upper strata is up-narrow and down-wide trapezoid structural member.
The utility model mechanical bit binary composite construction blank makes it compared with prior art owing to adopted above technical scheme, has following advantage and characteristics:
1, once rollingly can produce two cutter blanks, effectively reduce the production cost of composite machine blade cutter blank, reduce energy consumption, improve the utilization rate of steel;
2, can effectively save the edge of a knife allowance of each necessary blade of conventional composite construction;
3, can the narrow especially all kinds of mechanical bit blanks of compound shear steel, be used for the cutter blank of the narrow especially all kinds of mechanical bits of rolling shear steel.
Description of drawings
Fig. 1 is the structural representation of prior art mechanical bit binary composite construction blank;
Fig. 2 is the structural representation of the utility model mechanical bit binary composite construction blank.
The specific embodiment
Referring to Fig. 2, the utility model mechanical bit binary composite construction blank is double-deck polylith composite structural member, lower floor 21 is a big cutter hub steel (mild steel), and the upper strata is constituted by a shear steel 22 (alloy tool steel) and two blocks of cutter hub steel 23,24 (mild steel).Wherein, shear steel 22 is up-narrow and down-wide trapezoid structural member, and in the middle of being arranged on, two blocks of cutter hub steel 23,24 are symmetricly set on the both sides of shear steel 22, and driving fit links into an integrated entity between each piece cutter hub steel and the shear steel.
The utility model mechanical bit binary composite construction blank is when making, be that a shear steel 22 (alloy tool steel) and two blocks of cutter hub steel 23,24 (mild steel) are placed on the big cutter hub steel 21 (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, through mill milling, four steel perfect adaptations are integral make again.By changing the size of each piece cutter hub steel and shear steel, can make the composite blank of all kinds of mechanical bits.
Claims (2)
1, a kind of mechanical bit binary composite construction blank, be as shear steel with alloy tool steel, with the composite structural member of mild steel as the cutter hub steel, it is characterized in that: described blank is double-deck polylith composite structural member, and lower floor is a big cutter hub steel, and the upper strata is constituted by a shear steel and two blocks of cutter hub steel, wherein, in the middle of a shear steel was arranged on, two blocks of cutter hub steel were symmetricly set on the both sides of a shear steel, and driving fit links into an integrated entity between each piece cutter hub steel and the shear steel.
2, mechanical bit binary composite construction blank as claimed in claim 1 is characterized in that: a described shear steel that is arranged on the centre, upper strata is up-narrow and down-wide trapezoid structural member.
