Description

Efficient sawing head

technical field

The invention relates to a high-efficiency sawing head, belonging to the field of sawing processing equipment.

Background technique

There are more than ³ billion m2 of new buildings and more than 48 billion ^m2 of existing buildings in China that require aluminum doors, windows and curtain walls, etc. The annual output value of the aluminum door and window industry is over 100 billion yuan. However, the current sawing processing of these aluminum door and window profiles There are problems of low sawing efficiency and high energy consumption, one of the main reasons is that the equipment used for sawing is relatively backward.

Research and development is suitable for high-efficiency sawing heads, which is of great significance for realizing fully automatic, intelligent and efficient sawing, and for achieving the goals of green manufacturing, energy saving, consumption reduction and environmental protection.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an aluminum alloy sawing head that can overcome the above-mentioned defects, has high efficiency and low energy consumption. Its technical solutions are:

A high-efficiency sawing head includes a saw blade, a drive shaft, a compression blade, a compression nut and a water mist supply pipe, wherein the saw blade is radially supported on the drive shaft, and the compression nut passes through the compression blade along the shaft. In the direction of compression, the saw blade rotates along the W direction under the drive of the drive shaft; the compression plate, the compression nut and the water mist supply pipe are on the same side of the saw blade. It is characterized in that: the saw blade is provided with fork-shaped slits that penetrate the saw blade in the radial direction, and the fork-shaped slits are evenly distributed along the circumferential direction of the saw blade; Cylindrical face, pointing towards and close to the pressing face of the saw blade.

The high-efficiency sawing head should have at least 6 fork-shaped slits along the circumferential direction of the saw blade.

For the high-efficiency sawing head, the water mist supply pipe can be connected to a water mist supply system based on an ultrasonic water mist generator, a water mist supply system based on a molecular sieve evaporation water mist generator, or a high-pressure micro-mist water mist. The generator's water mist supply system.

In the high-efficiency sawing head, the saw blade is provided with at least two branches at the end of the fork-shaped slit that penetrates the saw blade in the radial direction.

Compared with the prior art, the present invention has the following advantages:

1. The cooling water cools the saw blade in the form of water mist driven by the airflow, and the cooling is uniform and efficient;

2. The cooling water is supplied in the form of water mist, which saves a lot of cooling water and does not need to filter and recycle the cutting fluid;

3. The forked slits on the saw blade play the role of cooling and damping at the same time.

Detailed ways

In the embodiment shown in FIG. 1 : it includes a saw blade, a drive shaft, a compression blade, a compression nut and a water mist supply pipe, wherein the saw blade is radially supported on the drive shaft, and the compression nut passes through the compression blade Compressed along the axial direction, the saw blade rotates along the W direction under the drive of the drive shaft; the compression plate, the compression nut and the water mist supply pipe are on the same side of the saw blade. It is characterized in that: the saw blade is provided with fork-shaped slits that penetrate the saw blade in the radial direction, and the fork-shaped slits are evenly distributed along the circumferential direction of the saw blade; Cylindrical face, pointing towards and close to the pressing face of the saw blade. Part of the water mist flows along the surface of the saw blade to the cutting teeth, and the other part flows into the fork-shaped slit of the saw blade, and moves along the slit until the fork-shaped branch reaches the edge of the saw blade, all of which play a role in cooling the saw blade.
