Description

Technical Field

[0001] This utility model relates to the field of steel cutting technology, and in particular to a quick-fixing mechanism for steel cutting. Background Technology

[0002] Steel cutting is an indispensable and crucial step in industrial production, widely used in construction, machinery manufacturing, automobile manufacturing, shipbuilding, and many other fields. How to quickly and accurately fix the steel during the cutting process, thereby improving cutting efficiency and quality, has always been a pressing issue for the industry.

[0003] Chinese patent publication number CN222470921U discloses a "Steel Cutting Flying Saw Machine with Easy Fixation." This device places the steel to be cut above a fixed base, and then rotates a handle. As the handle rotates, the clamping plate moves downwards, reaching the surface of the steel and thus fixing it in place. Compared to traditional devices, this device improves the stability of the steel during cutting by fixing it with a fixing mechanism, increasing the device's working efficiency and preventing steel movement during cutting, which could cause offset. The device also changes the cutting direction by starting a motor to rotate the cutting blade, and then starting a servo motor to rotate a gear, which in turn rotates the motor. This allows the cutting mechanism to change the cutting direction, improving the cutting efficiency and enabling the cutting mechanism to cut in different directions, increasing cutting versatility and overall cutting efficiency.

[0004] However, the fixed base in the above patent cannot be moved, which makes it impossible for multiple sets of clamping plates to clamp and fix steel of different widths, reducing the working efficiency of steel cutting. Therefore, we propose a quick fixing mechanism for steel cutting to solve the above-mentioned problems. Utility Model Content
