Abstract
The invention relates to a grooved shear blade with shear blade grooves on both sides of the body. Due to the fact that the shear grooves formed on both sides of the grooved shear blade body can be alternately used for cutting round steel, the service life of the grooved shear blade is twice as long as that of an existing grooved shear blade when the same materials are utilized.
Description
The present invention relates to a kind of trough of belt cutting edge.
Background technology
The general length scaling of existing round steel is 6-9 rice, will be cut to the length that needs in use, and the trough of belt cutting edge of existing cutting circular steel all is that a side has cutting edge groove (as shown in Figure 1).Because cutting edge mostly is to make with the alloy of 65Cr4W3Mo2VNb and so on, price comparison is expensive.Therefore, in use, the cutting edge groove requires the back just whole cutting edge groove to be discarded in case the generation wearing and tearing can not be satisfied to shear, and causes waste easily.Therefore, people press for and a kind ofly can prolong the cutting edge method in service life.
Summary of the invention
What the present invention will solve is how to prolong the cutting edge problem in service life.
For solving the problems of the technologies described above, the present invention adopts following skill scheme:
The cutting edge groove is all offered in both sides at the sword body of inventing a kind of trough of belt cutting edge.
The present invention is owing to all offer the cutting edge groove in the both sides of the sword body of trough of belt cutting edge, and the cutting edge groove of both sides can alternately be used for shearing round steel, and therefore under the situation of same material, its service life, more existing trough of belt cutting edge can prolong one times.
Description of drawings
Fig. 1 is the structural representation of existing trough of belt cutting edge.
Fig. 2 is structural representation of the present invention.
Fig. 3 is the A-A cutaway view (amplification) of Fig. 1
The specific embodiment
Referring to Fig. 2 and Fig. 3, the present invention all has cutting edge groove 2 in the both sides of its sword body 1.In order once to cut many round steel, the cross section of the cutting edge groove 2 of sword body 1 both sides is circular arc, and is more than one, is evenly distributed on sword body both sides, and certainly, the cross sectional shape of cutting edge groove also can be other shapes, so that the section bar of cutting different cross section shape.
For sword body 1 fixedly on the shearing machine, is had one fixing hole (present embodiment is 4) at least on the sword body 1.
Claims (6)
1. a trough of belt cutting edge is characterized in that the both sides of its sword body all have the cutting edge groove.
2. trough of belt cutting edge as claimed in claim 1 is characterized in that the cutting edge groove of sword body both sides is more than one.
3. trough of belt cutting edge as claimed in claim 1 is characterized in that the cutting edge groove of sword body both sides is even distribution
4. as claim 1 or 2 or 3 described trough of belt cutting edges, it is characterized in that the cross section of the cutting edge groove of sword body both sides is circular arc.
5. as claim 1 or 2 or 3 described trough of belt cutting edges, it is characterized in that sword has fixing hole on one's body.
6. trough of belt cutting edge as claimed in claim 5 is characterized in that sword fixing hole on one's body is at least one.
