Description

Silencing disc assembled on woodworking tool

Technical Field

The utility model relates to an amortization dish of assembly on woodworking tool belongs to cutter silencing device technical field.

Background

At present, most of the existing wood knife tools are not provided with a silencing device, and the noise generated when the tool works is reduced by arranging some S-shaped groove shapes on the tool or a saw blade matrix.

But along with the market to the requirement of the wood surface finish degree of processing more and more severer, and the amortization cutter that has the S-shaped cell type can influence the wood surface finish degree of processing, and along with the rotational speed of equipment constantly promotes, owing to its seting up the cell body and destroyed the wholeness of cutter or saw bit on the contrary can increase the noise because high rotational speed produces vibrations.

In the current carpenter production process, the source that the noise produced has: wind noise of the air suction device, noise generated when a cutting motor or a main shaft rotates, working noise of a cutter for cutting wood, resonance noise generated when a plurality of same or similar devices are placed in the same space, and the like.

When the cutter cuts the wood, the cut part of the wood is generated and the wood is accumulated, and the residue of the wood will additionally make the cutter continue to cut the wood, thereby increasing the generation of noise.

Disclosure of Invention

The utility model discloses the technical problem that will solve lies in: the utility model provides a amortization dish of assembly on carpenter's cutter, it has solved among the prior art because the residue of wood cutting leads to the cutter to continue to cut its problem many times of noise increase when cutter cutting timber.

The utility model discloses the technical problem that will solve takes following technical scheme to realize:

a silencing disc assembled on a woodworking tool comprises a tool body and a silencing disc installed on the tool body, wherein a first shaft hole is formed in the axial lead of the tool body, and a plurality of first screw holes are formed in the tool body around the first shaft hole;

the silencing plate comprises a plate body, the plate body is in a circular truncated cone shape, one end face of the plate body is a small-diameter circular face, and the other end face of the plate body is a large-diameter circular face;

a second shaft hole is formed in the position of the axis of the disc body of the silencing disc, a plurality of second screw holes are formed in the disc body around the second shaft hole, the diameter of the second shaft hole is equal to that of the first shaft hole, the second screw holes are consistent with the first screw holes in number, and the silencing disc and the cutter body are fixed through screws sequentially penetrating through the second screw holes and being in threaded connection with the first screw holes;

the tray body is provided with a plurality of circular arc angle grooves along the circumferential direction in sequence from the small-diameter circular surface to the large-diameter circular surface.

As a preferred example, the second screw hole is a counter-sunk hole.

As a preferred example, a convex circular arc angle is formed between two adjacent circular arc angle grooves.

The utility model has the advantages that: through fixing the amortization dish on the cutter body, amortization dish and the coaxial rotation of cutter body, at the cutter bodily rotation in-process, form the air current between the disk body of amortization dish and the cutter body, the air current can take out most wood along with the area arc angle slot on the amortization dish and cut to avoid the residue of wood, reduce the cutter and cut its many times again, thereby the production of noise abatement.
