Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with examples, but the implementation of the present invention is not limited thereto.

[0030] Such as Figure 1 ~ Figure 5 As shown, a cutting tool for cutting energetic materials is composed of a blade 1A and a shank 1B. The blade 1A is assembled on the positioning groove of the shank 1B by welding, and the bottom of the blade 1A is arranged to facilitate The positioning block 2F fixed by welding is convenient for welding and fixing. The rear end of the blade 1A is also provided with a groove 2G for the mating connection of the cutter bar 1B to increase the rigidity of the cutter. The welding seam 1C of the blade 1A and the cutter bar 1B is polished smooth. The blade structure and geometric angle are optimized for cutting energetic materials.

[0031] The front end of the insert 1A is provided with a major cutting edge of the tool consisting of a triangular cutting edge 2A and a flat edge 2B....

Abstract

The invention discloses a cutting cutter for cutting and processing an energetic material. The cutting cutter comprises a blade and a cutter bar; the blade is assembled on a positioning groove of the cutter bar in a welding manner; the front end of the blade is provided with a cutter main cutting edge which is composed of a triangular cutting edge and level blades; the front cutter face, corresponding to the triangular cutting edge and the level blades is an arc-shaped face; the rear cutter face of the cutter main cutting edge is arranged below the triangular cutting edge and extends to the bottom of the blade; the amount of the level blades is two; the level blades are connected with the two sides of the triangular cutting edge respectively; and an included angle between two edges of the triangular cutting edge is 80-100 degrees. According to the cutting cutter, a pit is prevented form occurring, the material removal rate is effectively reduced, a large-diameter energetic material can be cut under the condition with smaller material removal rate, and the cutting effect and the safety are good.

Description

Technical field [0001] The invention relates to the technical field of cutting and processing of energetic materials, in particular to a cutting tool used for cutting and processing of energetic materials. Background technique [0002] Because the mechanical properties of energetic materials are soft and brittle and weak rigid, brittle fracture is prone to occur during the cutting process, especially when the cutting tool cuts or cuts the position of the blank edge or block, and the energetic material has high energy, sensitivity and high The value and other characteristics bring tremendous pressure to the cutting process of energetic materials. At present, metal cutting tools have not optimized the tool structure for energetic materials, and are not suitable for cutting energetic materials, and their cutting effect and safety have certain deficiencies. [0003] When cutting the energetic material, the material is subjected to the combined action of centrifugal force, gravity and ...
