Preferably, a round hole is formed in the top end of the shear blade piece.

Compared with the prior art, the utility model has the beneficial effects that:

by the aid of the shear sheets, in the rotary shearing process, gaps between the shear sheets subjected to shearing in the prior shearing process can be increased due to the fact that the inner circular arcs of the shear sheets are designed, more fragments can be allowed to exist between the two shear sheets due to the design, the fragments and the shear sheet main body can be reduced to be bonded under the rotary acting force, shearing force applied to articles is guaranteed, and shearing effect is guaranteed.

Meanwhile, due to the arrangement of the grooves, the cutting edges of the shearing pieces are sharp, the shearing strength of the shearing pieces is ensured, and meanwhile, the grooves are used. The friction between the cutting edge and the other shear blade piece is reduced, so that the two shear blade bodies are more labor-saving and smoother when being meshed, and the using effect of the shear blade is improved.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, the present utility model provides a technical solution: the shear blade comprises a shear blade piece 1, wherein a groove 2 is formed in the inner side of the shear blade piece 1, a convex contour 3 is fixedly connected to the inner side of the shear blade piece 1, an included angle between the groove 2 and a shear plane of the shear blade piece 1 is 10-20 degrees, the inner side of the shear blade piece 1 is an arc, and the farthest distance between the inner side of the shear blade piece 1 and contact surfaces between the two shear blade pieces 1 is 0.5-1 mm.

The clip 1 and the raised profile 3 are of an integrally formed construction.

The front inclination angle of the cutting edge of the shear blade piece 1 is 20-30 degrees.

A round hole is formed in the top end of the shear blade piece 1.

The scissors pieces 1 pass through the round holes, so that the scissors pieces 1 and the other scissors piece 1 can rotate mutually, and the objects are sheared through the rotation of the scissors pieces 1.

As shown in fig. 4, where a is the angle between the groove 2 and the shearing surface of the blade-cutting member 1, the preferred angle in the present utility model is 15 degrees, and b is the rake angle of the edge of the blade-cutting member 1, and the preferred rake angle in the present utility model is 30 degrees, and by setting the groove 2 and the rake angle, the angle of the edge of the blade-cutting member 1 is reduced, so that the sharpness effect of the edge of the blade-cutting member 1 can be improved, and meanwhile, the friction generated between the edge and the article during shearing is reduced, and the shearing strength is improved.

As shown in fig. 2, where h is the furthest distance between the inner side of the clip 1 and the contact surface between two clips 1, the furthest distance is preferably 0.55mm in the present utility model, the inner side of the clip 1 is arc-shaped, and when an article is sheared during use, the subsequent shearing causes the gap between two clips 1 that have sheared the article before to become larger when the article is sheared.

As shown in fig. 5, during the shearing process, the inner side of the blade member 1 is arc-shaped, so that during the shearing process, the rotation of the blade member 1 shears an area where an article can be sheared at a previous position, when the article is sheared at a subsequent position, a gap is formed between two blades at the previous position, as the shearing process is performed, the distance between the two blades in the area becomes longer, a gap exists between the two blades in the area, and the design enables the area to realize anti-sticking after the article is sheared.

The design of the raised profile 3 is such that a smooth transition is achieved during the interdigitation, the raised profile 3 does not participate in the shearing process.

By the arrangement of the shear blade structure, during the rotary shearing process, the gap between the shear blade pieces 1 subjected to the shearing previously can be increased due to the circular arc design on the inner side of the shear blade pieces 1, and the design can allow more fragments to exist between the two shear blade pieces 1, so that the adhesion of the fragments and the shear blade main body under the action force on the rotary action force can be reduced, the shearing force on the articles is ensured, and the shearing effect is ensured; through the setting of recess 2 for the blade of piece 1 becomes sharp, has ensured the shear strength of piece 1, and the use of recess 2 simultaneously.
