Description

TECHNICAL FIELD

[0002] The disc cutter is a cutting device with a rotating disc blade as the core component, which is widely used in metal processing, stone mining, building material manufacturing and other fields. Its working principle is to drive the blade to rotate at high speed through the motor, and to realize precise cutting of materials in combination with the feeding system. When applied to cutting of anti-seismic support, it needs to be configured in combination with the material properties of anti-seismic support, cutting precision requirements and safety protection measures.

[0003] The anti-seismic support is usually made of metal materials such as steel and stainless steel, and a hard alloy or high-speed steel cutter needs to be selected. During the cutting process, the disc cutter blade is offset due to too much strength, the burr of the cut increases, and the processing quality of the anti-seismic support and other precision components is affected.

[0004] The traditional braking means relies on sensors or algorithms to predict dangerous working conditions, and only uses manual triggering of braking. Moreover, the impact force of the general braking means during emergency stop is easy to cause deformation of the main shaft or collapse of the gear of the transmission system, and the reset time after braking is long, which affects the continuous operation process and reduces the production efficiency.

[0043] With reference to Figure 3 , the mechanical claw tips 4011 also embed magnets that generate magnetic repulsion with the disc cutter 5.

[0044] With reference to Figure 2 and Figure 3 , when the disc cutter 5 is deviated due to the thrust of the cut object in the working process, the magnets therein generate magnetic repulsion on the mechanical claw tips 4011, so as to promote the upward movement of the mechanical claw tips 4011, and in this process, the transmission rod 4012 provided with gears also moves upward synchronously with the mechanical claw tips 4011, so as to promote the rotation of the planetary gear sets 4013, and then drive the further movement of the vibration suppression mechanism 402 through the mutual meshing of the gears of the centripetal gear mechanism 4014, and the whole process converts the slight deformation of the disc cutter 5 on one side of the main rotating shaft 6 into a larger form of deformation through the planetary gear sets 4013, and the deformation is inhibited and utilized in the subsequent structure.

[0045] With reference to Figure 4 , the two sides of the vibration suppression mechanism 402 are respectively fixedly connected with support rods 4035 through the sleeve 7, one side of the support rod 4035 is fixedly connected with a small annular rod 4034 near the main rotating shaft 6, six inner circular rods 4032 are uniformly distributed on the small annular rod 4034, and the other side of the support rod 4035 is fixedly connected with a large annular rod 4033, and six outer circular rods 4031 are uniformly distributed on the large annular rod 4033 corresponding to the positions of the inner circular rods 4032.

[0046] Referring to Figure 4 , the large ring-shaped rod 4033, the small ring-shaped rod 4034 and the support rod 4035 play the role of a framework, on which six groups of planetary gear sets 4013 are evenly arranged, and the movement thereof is set at a prescribed position, which only plays the role of amplifying deformation.

[0048] Referring to Figure 5 , the shapes and sizes of the fixed sliding block 4021 and the inclined sliding block 4022 match each other, converting the displacement in the horizontal direction into the displacement in the vertical direction, and promoting the further movement of the brake mechanism 404 and the hydraulic mechanism 4023 while pushing the inclined sliding block 4022 to move upward along the sleeve 7.
