Abstract
The utility model discloses a herringbone cutting edge shear blade of a steel bar shearing machine. The herringbone cutting edge shear blade comprises an upper shear blade, a lower shear blade, an upper tool apron, and a lower tool apron, wherein, the upper tool apron and the lower tool apron are fixed on the upper shear blade and the lower shear blade respectively; and the cutting edge of the upper shear blade as well as that of the lower shear blade adopts the shape that a plurality of herringbone cutting edges which are sunk to the inner side of a linear cutting edge are arranged on the linear cutting edge, and the herringbone cutting edge are arranged at intervals. The utility model has the beneficial effect that the herringbone cutting edges which are sunk to the inner side of the linear cutting edge are arranged on the linear cutting edge, so that the phenomenon that a blade is in single point-type contact with a steel bar while starting to shear the steel bar is eliminated, damage to a shearing cutting edge is reduced, the service life of the blade is remarkably improved; and the utility model further has the advantages of simple structure, easy manufacture, and reliable operation. As cutting edges are arranged on two sides of the upper shear blade as well as two sides of the lower shear blade respectively, the utility model can improve the utilization rate of the blade.
Description
Technical field
The utility model relates to the shear-blade of bar cutter, particularly be the herringbone blade shear-blade of bar cutter.
Background technology
Must dispose the shear-blade of shear reinforcement on bar cutter, this shear-blade comprises shear-blade and lower shear blade.The blade of the bar cutter shear-blade of prior art is a straight-blade type, that is, the blade of last shear-blade, lower shear blade is a straight line.There is following shortcoming in above-mentioned prior art bar cutter shear-blade when shear reinforcement:
1. in beginning during shear reinforcement, the blade of last shear-blade, lower shear blade contacts with the reinforcing bar single-point, cuts reinforcing bar and goes into the cutter difficulty, and the while is as easy as rolling off a log causes damage to shear-blade.
2. the service life of shear-blade is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of easy shear reinforcement is provided, and effectively protects shear-blade, prolongs the herringbone blade shear-blade of the bar cutter in shear-blade life-span.
The technical scheme that solves the problems of the technologies described above is: a kind of herringbone blade shear-blade of bar cutter, described herringbone blade shear-blade comprises: go up shear-blade and lower shear blade, fix described upper cutter head and the following tool rest of going up shear-blade and lower shear blade respectively, the described cutting edge shape of going up shear-blade and lower shear blade is: rectilinear edge is provided with a plurality of herringbone blades to the inboard depression of rectilinear edge, between the adjacent herringbone blade setpoint distance is arranged.
The utility model beneficial effect is: the utility model rectilinear edge is provided with a plurality of herringbone blades to the inboard depression of rectilinear edge, elimination is when the beginning shear reinforcement, the phenomenon that blade contacts with the reinforcing bar single-point type, reduce the damage of shearing knife edge, significantly improved the service life of blade.Have simple in structure, be easy to processing, the advantage of reliable operation.The utility model is respectively arranged with blade in the both sides of last shear-blade and lower shear blade, improves the utilization rate of blade like this.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is the utility model front view; Fig. 2 is an A portion enlarged drawing among Fig. 1.
The utility model provides a kind of herringbone blade shear-blade of bar cutter, and described herringbone blade shear-blade comprises: go up shear-blade 3 and lower shear blade 4, fix described upper cutter head 2 and the following tool rest 5 of going up shear-blade 3 and lower shear blade 4 respectively.
The described cutting edge shape of going up shear-blade 3 and lower shear blade 4 is: rectilinear edge is provided with a plurality of herringbone blades to the inboard depression of rectilinear edge, between the adjacent herringbone blade setpoint distance is arranged.
Angle α=90～175 of described herringbone blade °; Distance L=30～150mm between the adjacent herringbone blade.
As shown in Figure 2, the rectilinear edge of lower shear blade 4 is the level of state, described rectilinear edge inclination of going up rectilinear edge with the lower shear blade 4 of shear-blade 3, its angle of inclination beta=1～10 °.Between the rectilinear edge of the rectilinear edge of last shear-blade 3 and lower shear blade 4, be provided with skewedly, help the shearing of reinforcing bar.
As shown in Figure 1, shear-blade 3 and lower shear blade 4 both sides are respectively arranged with blade on described, this cutting edge shape is: rectilinear edge is provided with a plurality of herringbone blades to the inboard depression of rectilinear edge, between the adjacent herringbone blade setpoint distance is arranged, when the blade of a side was changed with blunt the needs, as long as the utility model changes a direction, the blade of opposite side is shear reinforcement timely, improves the utilization rate of blade like this.
Claims (4)
1. the herringbone blade shear-blade of a bar cutter, described herringbone blade shear-blade comprises: go up shear-blade and lower shear blade, fix described upper cutter head and the following tool rest of going up shear-blade and lower shear blade respectively, it is characterized in that the described cutting edge shape of going up shear-blade (3) and lower shear blade (4) is: rectilinear edge is provided with a plurality of herringbone blades to the inboard depression of rectilinear edge.
