Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the damage of a part of the blade of the cutting tool in the prior art needs to replace the entire tool, which is expensive to replace, and then provides a metal cutter that is not easy to break and has low replacement cost

Embodiment 1

[0021] figure 1 Shown is the metal cutter in this embodiment, the metal cutter includes several blades 1, the number of blades in this embodiment is 4, but not limited to this number, a guard 3 is arranged between the blades 1 and the rotating shaft 2, The protection device 3 includes a transmission part 32 fixedly arranged on the rotating shaft 2 and an elastic conduction part 33 arranged between two adjacent blades 1. The elastic conduction part 33 is a spring, and the transmission part 32 and the blade 1 can rotate relatively. connection, such as figure 2 As shown, in this embodiment, the transmission part 32 and the blade 1 are hinged through the hinge 6, and the hinge 6 is a screw and a nut, and may also be in other ways, such as a rivet. When cutting a hard material 4 with a hardness greater than the set hardness, the blade 1 is pushed by the hard material 4 to deflect in the anti-cutting direction and compress the elastic conductive member 33 until it is out of contac...

Abstract

The invention relates to a tool, in particular to a metal cutter. The metal cutter is arranged on a rotary shaft and comprises a plurality of blades, and a protection device is arranged between the blades and the rotary shaft. The protection device comprises a transmission component fixedly arranged on the rotary shaft, and the transmission component is hinged to the blades. An elastic conductingpart is arranged between every two adjacent blades. When a hard material with the rigidity larger than set rigidity is cut, the blades are pushed by the hard material to deflect back and forth in thecutting direction and compress the elastic conducting parts till the blades are out of contact with the hard material, and the blades are reset to the initial positions of the blades through the elastic conducting parts. The metal cutter aims at solving the technical problems that when one part of a cutting edge of a cutting tool in the prior art is broken, the whole tool needs to be replaced, andreplacement cost is high, and then the metal cutter is not prone to being broken and low in replacement cost.

Description

technical field [0001] The invention relates to a knife, in particular to a metal cutting knife. Background technique [0002] During the production or disassembly of metal products (such as pole pieces, flexible connections, battery cases, auto parts), metal products include materials with more than one hardness, and often have a mixture of materials with multiple hardness. When cutting with a tool When this material is mixed, tool breakage often occurs. [0003] Chinese patent document CN202192332U discloses a metal cutting sheet, which includes a cutting base, the center of the cutting base is provided with a fixing hole, and a number of cutting blades made of tungsten steel are evenly distributed on the edge of the cutting base, and the cutting blades and The cutting base is fixed or integrally formed. That is to say, the cutting knife body is rigidly connected with the cutting substrate. Therefore, during the cutting process, the knife is prone to breakage when it enc...
