Description

Cutting knife for cutting machine

Technical Field

The utility model relates to a cutting knife technical field specifically is a cutting knife for cutting machine.

Background

In order to facilitate the cutting of the pipes and the plates, a production unit can adopt a cutting machine or a cutting bed to cut, most of cutting machines adopt blades to operate, the cost is low, and the cutting is stable.

However, the blade part of the existing blade cutting machine is simple in structure and only is a disc made of alloy materials, when the blade cutting machine is used, the uniformity of a cutting surface can only be guaranteed, but burrs of the cutting surface cannot be processed when the blade is cut, and meanwhile, because the blade is thin, the central part is easy to deform and crack in the cutting process due to the fact that the rotating speed is too fast, the contact force is large, and the situation of deformation and cracking occurs.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cutting knife for cutting machine to solve present blade simple structure, only have the problem of cutting effect.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a cutting knife for cutting machine, includes the disc, the outer wall of disc is provided with a plurality of sword teeth, fixed embedding has the layer of polishing on the disc, it is provided with a plurality of gas pockets that run through the disc to polish on the layer, the ring has all been hugged closely to the center both sides of disc, fixed embedding has the lantern ring that runs through the disc on the ring, be provided with a plurality of first built-in holes on the disc, be provided with a plurality of second built-in holes on the ring, the threaded rod has been passed with the second built-in hole in the first built-in hole, the both ends threaded connection of threaded rod has the nut of hugging closely the ring.

Preferably, the disc and the cutter tooth are made of titanium alloy materials.

Preferably, the polishing layer is made of manganese steel material.

Preferably, the circular ring and the lantern ring are made of stainless steel materials, and the two lantern rings are spliced to form a finished shaft sleeve structure.

Preferably, the number of the first built-in holes and the number of the second built-in holes are not less than four, and the positions of the first built-in holes and the positions of the second built-in holes are in one-to-one correspondence.

Compared with the prior art, the beneficial effects of the utility model are that: this cutting knife for cutting machine through the layer of polishing on the disc, can polish the face after the cutting, and manganese steel material has good wear-resisting effect, and simultaneously, the ring and the lantern ring of cooperation central part can guarantee the cutting stability of middle part position when the blade is whole to be connected with the pivot.

In the figure: 1. a disc; 11. cutting teeth; 12. polishing the layer; 13. air holes; 14. a circular ring; 15. a collar; 16. a first built-in hole; 17. a second built-in hole; 18. a threaded rod; 19. and a nut.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 2 and fig. 3, the present invention provides a technical solution: a cutting knife for a cutting machine comprises a disc 1, wherein a plurality of knife teeth 11 are arranged on the outer wall of the disc 1, the disc 1 and the knife teeth 11 are made of titanium alloy materials and have enough hardness to ensure the cutting strength of the whole blade, a polishing layer 12 is fixedly embedded in the disc 1, the polishing layer 12 is made of manganese steel materials and can polish a cut surface when cutting, fine burr parts of the materials are processed, a plurality of air holes 13 penetrating through the disc 1 are formed in the polishing layer 12, a circular ring 14 is tightly attached to each of two sides of the center of the disc 1, a lantern ring 15 penetrating through the disc 1 is fixedly embedded in the circular ring 14, the circular ring 14 and the lantern ring 15 are made of stainless steel materials and can support the middle part of the blade to prevent the blade from being deformed and cracked due to the influence of the cutting strength, and the two lantern rings 15 are spliced into a complete shaft sleeve structure, the disc 1 is provided with a plurality of first built-in holes 16, the ring 14 is provided with a plurality of second built-in holes 17, the number of the first built-in holes 16 is not less than four than that of the second built-in holes 17, the first built-in holes 16 and the second built-in holes 17 are in one-to-one correspondence in position, threaded rods 18 penetrate through the first built-in holes 16 and the second built-in holes 17, and two ends of each threaded rod 18 are in threaded connection with nuts 19 tightly attached to the ring 14.
