Abstract

The utility model discloses a tilting shear knife of a steel bar shearing machine, which structurally comprises a shearing machine body, following parts are respectively fixed on the shearing machine body such as a lower knife block with a lower blade and an upper knife block with a tilting upper blade, a driving device is fixed on the shearing machine body, and the inclined angle Beta between the tilting upper blade and the lower blade ranges from 4 degrees to 15 degrees. The utility model has the benefits that the phenomenon that the blade is in contact with a plurality of steel bars when the steel bars are started to be sheared is eliminated, thereby improving the performance of the complete machine, reducing the shearing force, reducing the damage of the shear knife edge, obviously prolonging the service life of the blade. The utility model has the advantages of simple structure, reliable operation, and high shearing efficiency.

Description

Bar cutter Sloping Shearing cutter

Technical field

The utility model relates to the bar cutter shear knife, particularly be bar cutter Sloping Shearing cutter.

Background technology

Shear-blade and lower shear blade on bar cutter need dispose when shear reinforcement in the bar cutting production line.The bar cutter shear knife of prior art tilts to cut off that angle is very little 2 ° approximately, that is, the structure that this shear knife tilts to cut off angle is: the cutter that is installed in upper cutter head is with respect to bottom knife, and its angle of inclination is very little.

There is following shortcoming in above-mentioned prior art bar cutter shear knife when shear reinforcement:

1. when the beginning shear reinforcement, blade contacts with many reinforcing bars, and cutting off reinforcing bar needs very big shearing force;

2. during shear reinforcement, the blade sword that jumps easily, service life is short.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provide a kind of through experimental verification the employing cutter that is contained in upper cutter head tilt than the structure of wide-angle with respect to bottom knife, can realize high-quality shearing, the service life of having improved blade simultaneously.

The technical scheme that solves the problems of the technologies described above is: a kind of bar cutter Sloping Shearing cutter, and its structure comprises: the cutter body; On the cutter body, be fixed with respectively: the following tool rest that bottom knife is housed as lower member; The upper cutter head of tilting cutter is housed, on the cutter body, also is fixed with drive unit, described tilting cutter that is installed in upper cutter head and angle of inclination beta=4～15 between the bottom knife °.

The utility model beneficial effect is: eliminate when the beginning shear reinforcement, blade and the phenomenon that many reinforcing bars contact have improved machine performance, have reduced shearing force, have reduced the damage of shearing knife edge, have significantly improved the service life of blade.Have simple in structure, reliable operation, the advantage that shear efficiency is high.

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.

As shown in Figure 1 and Figure 2, the utility model provides a kind of bar cutter Sloping Shearing cutter, and its structure comprises: cutter body 1; On cutter body 1, be fixed with respectively: the following tool rest 5 that bottom knife 4 is housed as lower member; The upper cutter head 2 of tilting cutter 3 is housed, on cutter body 1, also is fixed with drive unit 7.

Described tilting cutter 3 that is installed in upper cutter head 2 and angle of inclination beta=4～15 between the bottom knife 4 °.

Described angle of inclination beta=8 °.

Below the course of work of the present utility model is described.

When needs shear reinforcement 6, drive unit 7 promotes upper cutter head 2 and tilting cutter 3 moves downward reinforcing bar 6 cut-outs.Finish above-mentioned action, drive unit 7 drives upper cutter head 2 and tilting cutter 3 is return original position, so just finishes one and shears circulation.Because the inclination angle between the utility model tilting cutter 3 and the bottom knife 4 is greater than the angle of inclination of prior art, in the process of shear reinforcement, blade is not easy the sword that jumps, the blade long service life.

Claims

1. bar cutter Sloping Shearing cutter, its structure comprises: cutter body (1); On cutter body (1), be fixed with respectively: the following tool rest (5) that bottom knife (4) is housed as lower member; The upper cutter head (2) of tilting cutter (3) is housed, on cutter body (1), also is fixed with drive unit (7), it is characterized in that, described tilting cutter (3) that is installed in upper cutter head (2) and angle of inclination beta=4～15 between the bottom knife (4) °.

2. according to the bar cutter Sloping Shearing cutter described in the claim 1, it is characterized in that described angle of inclination beta=8 °.
