Description

Anti-chip removal structure of cutter

Technical Field

The utility model relates to a cutter anti-chip removal structure used in the milling field.

Background

When the existing cutter is used for milling, the aluminum scraps flow along with the flowing direction of the external cutting fluid, so that the cut aluminum scraps flow into the product cavity, the cleanliness of the product is unqualified, and the production requirement cannot be met. Therefore, after the processing is finished, the aluminum scraps falling in the product cavity are manually blown off by an air gun to be cleaned. But the cleaning process is still inefficient and ineffective.

Disclosure of utility model

The utility model aims to overcome the defects in the prior art, and provides a cutter anti-chip removal structure which can automatically remove chip scraps.

The cutting fluid flow channel is axially arranged in the center of the cutter body, the cutting fluid flow channel is led to the bottom of the cutter body, the bottom of the cutter body is provided with a water containing groove, an outlet of the cutting fluid flow channel is opposite to the center of the water containing groove, a group of water outlet holes are formed in each milling surface of the side surface of the water containing groove corresponding to the cutter body, and the water outlet holes are led to the water containing groove.

Furthermore, a back flushing surface is arranged in the direction of the water containing tank leading to the water outlet.

Further, each group of water outlet holes consists of an upper water outlet hole and a lower water outlet hole which are sequentially arranged from top to bottom.

Further, the bottom surface of the orifice part of each water outlet is an upward slope, the direction of the slope is opposite to the feeding direction of the cutter, and the included angle between the slope of the orifice bottom of the upper water outlet and the vertical direction is smaller than the included angle between the slope of the orifice bottom of the lower water outlet and the vertical direction.

Further, the included angle between the slope of the bottom of the orifice of the upper water outlet and the vertical direction is 30 degrees, and the included angle between the slope of the bottom of the orifice of the lower water outlet and the vertical direction is 60 degrees.

The anti-chip removal structure of the cutter has the advantages that the anti-chip removal structure of the cutter adopts the structure that the cutting fluid impacts the water containing groove at the bottom of the cutter body and then is backflushed by the water outlet, so that in the processing process, the aluminum scraps generate a movement trend of flowing outwards of the cavity along with the flowing direction of the cutting fluid, and the quantity of the aluminum scraps reserved in the cavity can be greatly reduced. Therefore, the workload of manually blowing operation after processing can be reduced, the production efficiency is improved, and meanwhile, the cleanliness of the product is improved.

Detailed Description

In order to better understand the technical solution of the present utility model, the following detailed description is given by way of specific examples:

Referring to fig. 1, in the anti-chip removing structure of the cutter, a cutting fluid flow channel 1 is axially arranged in the center of the cutter body, the cutting fluid flow channel 1 is connected with a cutting fluid circulation system, and the cutting fluid circulation system and the cutter are controlled by a numerical control machine tool. The cutting fluid circulation system pumps the cutting fluid into the cutting fluid flow passage 1 at a high speed.

The cutting fluid flow passage 1 is led to the bottom of the cutter body, the bottom surface of the cutter body is provided with a water containing groove 2, and the outlet of the cutting fluid flow passage 1 is opposite to the center of the water containing groove 2. The direction of the water containing tank 2 leading to the water outlet hole is provided with a back flushing surface 3, and the back flushing surface 3 is positioned on the opposite side of the water outlet hole. The backflushing surface 3 can enable the cutting fluid to perform backflushing towards the water outlet hole to achieve a better effect.

After the cutting fluid in the cutting fluid flow channel 1 is sprayed out, the recoil surface 3 of the impact water containing groove 2 forms recoil force. Each milling surface of the corresponding cutter body on the side surface of the water containing tank is provided with a group of water outlet holes which are communicated with the water containing tank 2. When the cutting fluid is backflushed, the cutter body is sprayed out through the water outlet, and scraps generated when the cutter body performs cutting operation are taken out of the cavity.

In this embodiment, each group of water outlet holes is composed of an upper water outlet hole 4 and a lower water outlet hole 5 which are sequentially arranged from top to bottom. The bottom surface of the orifice part of each water outlet is an upward slope, the direction of the slope is opposite to the feeding direction of the cutter, and the included angle between the slope of the orifice bottom of the upper water outlet and the vertical direction is smaller than the included angle between the slope of the orifice bottom of the lower water outlet and the vertical direction. In this embodiment, the included angle a between the slope of the bottom of the orifice of the upper water outlet and the vertical direction is 30 °, and the included angle b between the slope of the bottom of the orifice of the lower water outlet and the vertical direction is 60 °. The spray angles of the cutting fluid at the upper water outlet and the lower water outlet are different, so that the spray dispersion effect of the cutting fluid can be improved. The specific number of water outlets is not specifically limited, and the water outlets are used to spray the back-flushing cutting fluid to the outside of the cavity to be machined through the water outlets, rather than flowing along the cutter body in the feeding direction, so that the cutting chips can be carried away as much as possible.

Referring to fig. 2, the steps for implementing the present utility model are as follows:

1. Because the diameter of the cutter body is larger than that of the traditional cutter, the aperture size of the cavity to be machined needs to be confirmed in advance before the result of the cutter is adopted to meet the requirement of the cutter.

2. And (3) confirming whether the blank to be processed has a pre-cast hole, and if so, directly processing by using the cutter of the utility model. If no pre-cast hole exists, a drill bit with a diameter smaller than the machining aperture can be used for pre-drilling, and then the cutter is used for machining.

3. During machining, the internal program cooling instruction of the numerical control machine tool is firstly opened, the cutting fluid circulation is started, and then machining is performed. As shown in fig. 2, the arrow direction is the feeding direction, and the cutting fluid is back-flushed to the outside of the cavity during the machining process, opposite to the feeding direction, so that most of the cutting chips are discharged to the outside of the cavity along with the flow direction of the cutting fluid.

It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
