Description

Technical Field

[0002] Aluminum alloy window frames are made of aluminum alloy and are widely used in residential, commercial, and office buildings, as well as various construction projects. Aluminum alloy is a low-density metal, only one-third the density of steel, making the resulting window frames relatively light. However, it is strong enough to withstand certain external forces and possesses strong structural stability. Furthermore, a naturally formed oxide film on the surface of aluminum alloy effectively resists erosion by water, air, and other corrosive substances, making aluminum alloy window frames ideal for use in humid or corrosive environments, such as those near the sea. Due to their excellent physical and chemical properties, such as lightness, high strength, and corrosion and oxidation resistance, aluminum alloy window frames have become a very popular choice in modern architecture.

The synchronization rod 415 drives the mounting block 410 to move synchronously, and the fourth gear plate 414 drives the third gear 413 and the grinding roller 412 to rotate to grind the cross section of the aluminum alloy window frame, further eliminating cross-section burrs and improving processing quality.

[0060] After the impact cylinder 305 drives the cutter 302 to fall and cut the aluminum alloy window frame, the cutter 302 extends into the liquid accumulation tank 501 to dissipate heat from the cutter 302. When the cutter 302 descends, it drives the pressure block 509 to move downward synchronously, pressing down the contact block 508, driving the piston 505 to move downward, and the second one-way valve 511 is connected, sending the coolant into the nozzle 502 and spraying it onto the surface of the cutter 302 from the nozzle hole 503. While dissipating heat from the cutter 302, the iron filings on its surface are cleaned for easy use.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
