Description

Technical Field

[0001] This utility model belongs to the technical field of profile sawing machines, and in particular relates to a high-rigidity profile sawing machine. Background Technology

[0002] Profiles refer to materials with a consistent cross-sectional shape and a relatively long length, including steel profiles, aluminum profiles, plastic profiles, and copper profiles. Typical profiles frequently used in construction include channel steel, angle steel, flat steel, I-beams, H-beams, round tubes, square tubes, special-shaped tubes, and bars. Profiles are widely used, and sawing is one of the most common processing methods in the field of profile processing.

[0003] The profile sawing machines currently on the market have the following problems when used:

[0004] 1. Traditional profile sawing machines, when actually cutting, can usually only use a saw blade of a specified size, or use a large saw blade to cut small parts. Since the cross-sectional dimensions of profiles vary greatly, while the sawing machine can use saw blades of different sizes, it is not suitable for cutting profiles with different cross-sectional dimensions.

[0005] 2. Most profile sawing machines require a feeding frame and guide rails for actual feeding due to their large size. The clamps need to be changed for different profile specifications, making feeding relatively inconsistent.

[0006] 3. Traditional profile sawing machines typically do not have a fixed base installed on the outside of the sawing mechanism when they are fixed, and the frame does not have a box-type structure. They require regular maintenance by staff after frequent use, resulting in poor external rigidity and being uneconomical and impractical.

[0007] 4. In most profile sawing machines, the saw blade does not move smoothly enough during cutting, resulting in uneven force on the saw blade. In addition, the saw blade does not have a stable structure installed, so the cutting is not smooth enough and the durability is weak. Utility Model Content

[0049] The working principle of this high-rigidity profile sawing machine is as follows: When cutting profiles, the machine employs a height-adjustable structure, allowing operators to use saw blades of varying sizes to accommodate profiles with different cross-sectional dimensions. This makes it very convenient to use. The profile to be sawed is placed inside the machine for processing, and feeding is achieved through a roller feed encoder that provides feedback on the feeding position. This results in a compact overall structure and a small machine size. No feeding frame or guide rails are required during operation, making it easy to use. It can process different profiles without changing clamps; operation simply requires adjusting the clamping opening. For ease of installation, a box-shaped column is used as the mounting base for the sawing mechanism, and the frame also adopts a box-shaped structure. This provides good rigidity and light weight, making it economical and practical. During the sawing process, a servo motor drives the lead screw to rotate, which in turn drives the sawing mechanism to cut. This ensures smooth operation and even force distribution on the saw blade, effectively improving its durability. Furthermore, the saw blade stabilization structure further improves the saw blade's cutting performance, resulting in more uniform and smooth cuts, thus enhancing its durability and making the sawing machine highly practical.

[0050] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
