Description

A kind of plate shearing machine scissors

Technical field

The utility model relates to the New-type sheet scissors on a kind of plate shearing machine, and particularly a kind of the novel scissors that is out of shape and clamping device when preventing from shearing overlength sheet metal, belong to shearing working processes of metals technical field.

Background technology

Some sheet metal shearings are often run in shearing working processes of metals, relate to when being shearing overlength sheet metal especially, normal shear knife adds and there will be the overlength sheet metal that is sheared man-hour and produce the phenomenons such as torsion, distortion, cause product quality and efficiency poor, can not meet reality produce in needs.Cause the reason of above-mentioned deficiency relevant with the shear knife on plate shearing machine to a great extent, if adopt laser cutting overlength sheet metal, production cost can be caused sharply to rise,

Therefore, need to innovate the shear knife on plate shearing machine, the scissors of prior art does not reach technical requirement, as the utility model CN203778868U announced, its scissors is combined by multiple blade, each blade combining scissors in production easily misplaces, loosen, the linearity of scissors does not reach requirement, practicality is inadequate, and the utility model is exactly a kind of new shear knife solving above technical deficiency.

The utility model manufacture is simple, and adjustment and installation is convenient, and result of use is good, long service life, and can Reusability, practical.

Utility model content

The purpose of this utility model is to provide a kind of plate shearing machine scissors, in particular to a kind of Novel scissors cutting knife and the clamping device of shearing overlength sheet metal, using when shearing overlength sheet metal, overlength sheet metal can be avoided to produce the phenomenons such as torsion, distortion and can obtain more smooth overlength sheet metal.

The purpose of this utility model is achieved through the following technical solutions, and a kind of plate shearing machine scissors, comprises scissors and clamping device.

Described scissors is provided with shaped form blade, cutter hub, carves type handle of a knife; It is characterized in that: scissors is rectangle tabular, and below is processed with shaped form blade by numerically control grinder, preferably shaped form is quadratic function curve, and shaped form blade is at least provided with two contour high points, is provided with and carves type handle of a knife in the middle of cutter hub upper end;

Described clamping device is provided with clamping groove and carves type latch segment; It is characterized in that: described clamping groove Right vertical direction milling waist through hole, preferably milling waist through hole is six, every two keep at a certain distance away as one group, the clamping groove left side, centre, location right respectively establish one group, its width mates with the diameter of bolt carving type latch segment, carve between type latch segment position and be provided with rectangle breach, described in carve type latch segment and be provided with two bolts for carving block right side horizontal direction, bolt is perpendicular to carving block right side;

Further, described cutter hub is high-quality tool steel.

Further, described shaped form blade is through Quenching Treatment.

Further, described clamping groove height is less than the height carving type handle of a knife.

Further, described in carve type latch segment two bolts the distance of spacing and one group of waist through hole interval mate, two bolt length are greater than waist through hole thickness.

Compared with prior art, the utility model has following beneficial effect:

The first, shaped form blade can reduce shearing force, is conducive to scissors service life.

The second, shaped form blade has two contour high points at least, can when shearing overlength sheet metal, two-point locating, active force is cancelled out each other, and not only can obtain more smooth sheet metal, and improve the service life of scissors, significantly improve crudy and operating efficiency.

3rd, scissors can utilize numerically control grinder repeatedly sharpening, Reusability.

4th, the clamping groove that clamping device is provided with and to carve when type latch segment makes adjustment scissors easily and fast, accurately.

5th, clamping groove height is less than carves type handle of a knife height, make scissors shear time can not be excessive and loosening because of shearing force, affect result of use, can significantly improve crudy and operating efficiency.

In figure: 1 clamping device, 2,7,10 carve type latch segment, 3 cutter hubs, 4 scissors, 5 breach, 6 high points, 8 shaped form blades, 9 clamping grooves, 11 waist through hole, 12 bolts, and 13 carve block, and 14 carve type handle of a knife, and 15 carve right side, face 15,16,17 nuts.

Detailed description of the invention

As shown in Figure 1, Figure 2, Figure 5, a kind of plate shearing machine scissors, comprises scissors 4 and clamping device 1.

Described scissors 4 is provided with shaped form blade 8, cutter hub 3, carves type handle of a knife 14, scissors 7 is rectangle tabular, below is processed with shaped form blade 8 by numerically control grinder, preferably shaped form is quadratic function curve, shaped form blade 8 is at least provided with two contour height points 6, is provided with and carves type handle of a knife 14 in the middle of cutter hub 3 upper end.

Described clamping device 1 is provided with clamping groove 9 and carves type latch segment 2,7,10, described clamping groove 9 Right vertical direction milling waist through hole 11, preferably milling waist through hole 11 is six, every two keep at a certain distance away as one group, clamping groove 9 left side, centre, location right respectively establish one group, its width and bolt 12 diameter matches carving type latch segment 2,7,10, carve between type latch segment 2,7,10 position and be provided with rectangle breach 5, further, clamping groove 9 is highly less than the height carving type handle of a knife 14;

As shown in Figure 3, Figure 4, describedly carve type latch segment 2,7,10 as shown in Figure 3, Figure 4, two bolts 12 are provided with for carving block 13 right side 16 horizontal direction, bolt 12 is perpendicular to carving block 13 right side 16, carve block 13 left side to carve face 15 and carve type handle of a knife 14 and mate, further, the distance at the spacing of two bolts 12 and one group of waist through hole 11 interval is mated, and two bolt 12 length are greater than waist through hole 11 thickness.

During use, to the bolt 12 of type latch segment 2,7,10 be carved through waist through hole 11, it is made to be close on the right side of clamping groove 9, as shown in Figure 2, carve type handle of a knife 14 and insert clamping groove 9 by carving block 13, now observe scissors 4 position by rectangle breach 5, and adjust scissors 4 and make to carve type handle of a knife 14 and prop up bottom clamping groove 9, adjustment is carved type latch segment 2,7,10 and is carved block 13 up and down, makes scissors 4 in place easily and fast, accurately, will carve type latch segment 2,7,10 be fastened on clamping groove 9 by nut.

By a kind of plate shearing machine scissors of the utility model, start plate shearing machine when shearing overlength sheet metal, the height point 6 that two of shaped form blade 8 are contour, two-point locating on overlength sheet metal, active force is cancelled out each other, and can not make thin plate distortion in shear history, obtains more smooth sheet metal.

After the blunt damage of scissors 4 shaped form blade 8, unclamp the nut 17 carving type latch segment 2,7,10, unload lower scissors 4 and utilize numerically control grinder sharpening, Reusability.
