technical field

The invention relates to a high-efficiency aluminum alloy sawing device, which belongs 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.

The research and development of a sawing device suitable for high-efficiency aluminum alloys is of great significance for realizing fully automatic, intelligent and high-efficiency 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 device that can overcome the above-mentioned defects, has high efficiency and low energy consumption. Its technical solutions are:

A high-efficiency aluminum alloy sawing device includes a saw blade, a drive shaft, a compression nut and a water mist supply pipe, wherein the saw blade is radially supported on the drive shaft, and is axially pressed by the compression nut, and the saw blade is The drive shaft rotates along the W direction; 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 slits penetrating the saw blade in the radial direction, and 12 slits with the same size are evenly distributed along the circumferential direction of the saw blade; The radial groove, the convex direction of the two sides of the groove is consistent with the rotation direction W of the saw blade, and the 20 grooves with the same size are evenly distributed along the circumferential direction of the compression nut; The mist outlet is near and pointed towards the center of the non-compression end face of the compression nut.

The high-efficiency aluminum alloy sawing device should have at least 6 slits along the circumferential direction of the saw blade.

The high-efficiency aluminum alloy sawing device, the water mist supply pipe and the water mist supply system based on the ultrasonic water mist generator, the water mist supply system based on the molecular sieve evaporation water mist generator or the water mist supply system based on the high pressure micro-mist water mist generator Either connection in the mist supply system.

The high-efficiency aluminum alloy sawing device should have at least 6 grooves along the circumferential direction of the compression nut.

In the high-efficiency aluminum alloy sawing device, the saw blade is provided with a slit that penetrates the saw blade in the radial direction, which can be a straight line or a smooth curved shape 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 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 nut and a water mist supply pipe, wherein the saw blade is radially supported on the drive shaft, and is axially compressed by the compression nut, and the saw blade is radially supported on the drive shaft. Rotate along the W direction under the drive of the drive shaft; the compression nut and the water mist supply pipe are on the same side of the saw blade. The saw blade is provided with slits penetrating the saw blade in the radial direction, and 12 slits with the same size are evenly distributed along the circumferential direction of the saw blade; the non-compression end face of the compression nut is provided with radial recesses groove, the convex directions of the two sides of the groove are consistent with the rotation direction W of the saw blade, and 20 grooves with the same size are evenly distributed along the circumferential direction of the compression nut; the mist outlet on the water mist supply pipe is close to And point to the center of the non-compression end face of the compression nut. The water mist supply pipe sprays cooling water mist at the mist outlet, and the groove on the compression nut generates negative air pressure during the rotation process, and the cooling water mist is evenly inhaled onto the saw blade, and a part of the water mist flows along the surface of the saw blade to the surface of the saw blade. The cutting teeth and the other part flow into the slit of the saw blade, which both play a role in cooling the saw blade.
