Description
Technical field
The utility model relates to a kind of blade that is used for angle shear.
Background technology
The purposes of angle shear is the unfilled corner that cuts specific standard on plate.For example: in the process that airduct is produced, need to adopt angle shear on plate, to cut unfilled corner in advance, just can carry out the bending of plate, otherwise can not make and the perpendicular flange portion in airduct side.The blade of angle shear is divided into cutter and bottom knife.As shown in Figure 1 and Figure 2, cutter is much of left blade 1 ' relatively by shape and last right blade 2 ' is put together with certain included angle: the right-hand member at last left blade 1 ' is provided with an inclined-plane, left end at last right blade 2 ' is provided with an inclined-plane, match each other between two inclined-planes, be in the same place with last right blade capable assembling so go up left blade, and form a upward shear angle α.Existing left blade and last right blade amalgamation after, the height away from the cutting edge of mosaic can be low more more.As shown in Figure 3, when on being installed in, cutting seat 3 ' cutter 5 ' and from up to down moving, its will be fixed on down the bottom knife 6 ' of cutting seat 4 ' and match, shear to the inside of plate from the edge of plate, finally punching goes out unfilled corner.
Above-mentioned last left blade and last right blade have only a kind of amalgamation form, that is: the height away from the cutting edge of mosaic is low more more.Though this amalgamation form shear history is comparatively steady, the impact that blade is subjected to is less, cuts seat on during each punching all must cover whole process, and punching efficient is lower.For improving shear angle efficient, need the blade of existing angle shear be improved.
Summary of the invention
The purpose of this utility model provides a kind of angle shear blade with two kinds of amalgamation forms.
For achieving the above object, the utility model is taked following technical scheme:
A kind of blade of angle shear comprises first blade and second blade, is provided with right tilted surface at the right-hand member of first blade, and first cutting edge upwards is tilted to the right after the lower end of first blade is provided with installation; Left end at second blade is provided with left tilted surface, and second cutting edge upwards is tilted to the left after the lower end of second blade is provided with installation; The left tilted surface of the right tilted surface of first blade and second blade match each other and capable assembling together, constitute first kind of amalgamation form; In addition, also be provided with left tilted surface, also be provided with right tilted surface at the right-hand member of second blade at the left end of first blade; The right tilted surface of the left tilted surface of first blade and second blade also match each other and capable assembling together, constitute second kind of amalgamation form.
By above technical scheme, first blade is arranged on the left side, second blade is arranged on the right,, can constitute first kind of amalgamation form of " the cutting edge height away from the mosaic is low more more " with both amalgamations together.Second blade is arranged on the left side, first blade is arranged on the left side,, can constitute second kind of amalgamation form of " the cutting edge height away from the mosaic is high more more " with both amalgamations together.First kind of amalgamation form of cutter is applicable to the shear angle situation that plate is thicker or angle is big or the arm of angle is long.Second kind of amalgamation form of cutter and since with on cut seat decline, blade is to shear to the edge from the inside of plate, so on cut seat and only need short stroke just can finish the shearing of plate.Cut the position of the travel switch of seat in the adjustment, cut the stroke distances of the single working cycles of seat in the shortening, can improve the punching efficient of angle shear.The cutter that is in second kind of amalgamation form is applicable to the shear angle situation that plate is thin or angle is less or the arm of angle is short.
Learn first kind of corresponding a kind of constituted mode of going up shear angle of amalgamation form easily; Second kind of corresponding another kind of constituted mode of going up shear angle of amalgamation form.Though two kinds of formed angular ranges of going up shear angle of constituted mode of going up shear angle might be overlapped, but consider two kinds of amalgamation forms suitable shear angle situation separately, the angle lower limit of the last shear angle under second kind of amalgamation form is preferably less than the angle lower limit of the last shear angle under first kind of amalgamation form.Like this, cutter can cut the less unfilled corner of angle in thin plate upper punch with its second kind of amalgamation form.
The utlity model has following advantage:
1) simple in structure, reliability and durability;
2) a cover blade has two kinds of usages, can select wherein a kind of suitable method according to the specification of plate and shear angle;
3) can save expensive blade cost.

The specific embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As Fig. 4, shown in Figure 5, the blade of angle shear comprises first blade 1 and second blade 2.Right-hand member at first blade 1 is provided with right tilted surface 3, and first cutting edge 4 upwards is tilted to the right after the lower end of first blade 1 is provided with installation.Left end at second blade 2 is provided with left tilted surface 5, and second cutting edge 6 upwards is tilted to the left after the lower end of second blade 2 is provided with installation.The right tilted surface 3 of first blade 1 and the left tilted surface 5 of second blade 2 match each other and capable assembling together, constitute first kind of amalgamation form of " the cutting edge height away from the mosaic is low more more ", and form and go up shear angle α 1.
As Fig. 5, shown in Figure 7, also be provided with left tilted surface 7 at the left end of first blade 1, also be provided with right tilted surface 8 at the right-hand member of second blade 2.As Fig. 6, shown in Figure 7, the left tilted surface 7 of first blade 2 and the right tilted surface 8 of second blade 2 also match each other and capable assembling together, constitute " the cutting edge height away from the mosaic is high more more " second kind of amalgamation form, and form and go up shear angle α 2.
In the present embodiment, the angle of the right tilted surface 3 of first blade 1 is 30 °, and the angle of left tilted surface 7 is 15 °.The angle of the left tilted surface 5 of second blade 2 is 30 °, and the angle of right tilted surface 8 is 15 °.So under first kind of amalgamation form, be limited to 60 ° under the angle of last shear angle α 1; Under second kind of amalgamation form, be limited to 30 ° under the angle of last shear angle α 2.For the angle upper limit of last shear angle, strict regulations not generally speaking, but for the required shear angle specification of airduct, the angle upper limit of last shear angle is at 150 ° promptly enough.
In addition, under second kind of amalgamation form, blade is to shear to the edge from the inside of plate, and this moment, first cutting edge 4 and second cutting edge 6 touched the resistance maximum that the position of plate is subjected to earlier.As Fig. 4, shown in Figure 6, for reducing the probability that fractures at this position of cutting edge, present embodiment first cutting edge (4) is provided with a blunt blade tip (9) near the position of the left tilted surface (7) of first blade (1), and second cutting edge (6) also is provided with a blunt blade tip (10) near the position of the right tilted surface (8) of second blade (2).
Cut on the seat for ease of first blade 1 and second blade 2 are fastened on, first blade 1 and second blade 2 of present embodiment are respectively equipped with installing hole 11, and the shape of first blade 1 and second blade 2 is symmetrical.
What this specification was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under operation principle of the present utility model and thinking all are considered as protection domain of the present utility model.
