Description

Technical Field

[0001] This invention relates to the field of door and window cutting technology, specifically to a thermal break aluminum alloy door and window cutting device. Background Technology

[0002] Thermally broken aluminum alloy doors and windows are an "upgraded version of insulation" for ordinary aluminum alloy doors and windows. By adding nylon thermal insulation strips (PA66) with poor thermal conductivity in the middle of the aluminum alloy profile, the metal "bridge" is broken, thereby effectively preventing direct heat conduction between indoors and outdoors, solving the problem of "cold in winter and hot in summer" of ordinary aluminum alloy doors and windows.

[0003] A search revealed a Chinese patent with application number "CN202511077858.2", which specifically describes a cutting device for thermally broken aluminum alloy doors and windows. The device includes a machine body, an operating table, a drive frame, and a cutting mechanism. The operating table is fixedly connected to the upper surface of the machine body. A left support is fixedly connected to the side surface of the operating table, and a right support is fixedly connected to the side surface of the operating table. The drive frame is fixedly connected to the upper surface of the operating table. The cutting mechanism is installed in the drive part of the drive frame. A drive device is provided on the surface of the left support, and a pneumatic clamping device is provided on the surface of the drive device.

[0004] In the processing of thermally broken aluminum alloy doors and windows, to achieve a 45° angle splicing of the frame and sash members, symmetrical angle cutting is required at both ends of the profile. However, most current single-head cutting equipment can only complete cutting operations in one direction and cannot achieve symmetrical 45° angle cutting at both ends of the profile. Therefore, existing processes often use a single-head saw in a step-by-step manner: first, one end of the profile is cut, and then the other end is cut manually or by a robot to turn the direction or reposition it. This step-by-step processing method is not only cumbersome and inefficient, but also prone to cumulative errors due to multiple clamping and positioning, directly affecting the sealing performance and structural strength of the splice, making it difficult to meet the high-precision and high-efficiency large-scale production requirements of thermally broken aluminum alloy doors and windows.

[0005] Therefore, this invention proposes a cutting device for thermally broken aluminum alloy doors and windows to solve the problems mentioned above. Summary of the Invention

[0032] The lifting assembly 33 includes a vertical plate 331, which is fixedly connected to the upper side of two guide blocks 32. A lifting groove 332 is formed on the outer side of the vertical plate 331, and a lifting block 333 is slidably connected to the inner side of the lifting groove 332.

The mounting cylinder 334 drives the lifting block 333 to descend. The lifting block 333 drives the front plate 341 to descend. The front plate 341 drives the cutting disc 365 to descend, facilitating the cutting disc 365 to cut the door frame parts, creating two symmetrical 45-degree bevels for easier assembly later.

The U-shaped plate 374 drives the inclined plate 372 to rotate. The inclined plate 372 drives the rear block 371 to move. Since the inclined plates 372 on both sides are symmetrically distributed, the rear blocks 371 on both sides move towards each other, which makes it easy to control the distance between the vertical plates 331 on both sides and adjust the distance between the two cutting discs 365, which is convenient for cutting door frame parts of various sizes.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] Working principle: When two symmetrical bevels (45 degrees) need to be cut on the door frame, the electric push rod 348 is controlled. The electric push rod 348 drives the rotating plate 347 to rotate, the rotating plate 347 drives the control ring 346 to rotate, the control ring 346 drives the rotating shaft 345 to rotate, the rotating shaft 345 drives the mounting plate 344 to rotate, and the mounting plate 344 drives the cutting disc 365 to rotate around the axial direction of the rotating shaft 345, which facilitates changing the cutting angle. At this time, the motor 363 is started, and the motor 363 drives the control shaft... Rotating 364, the control shaft 364 drives the cutting disc 365 to rotate, then the control hydraulic cylinder 336 drives the lifting plate 335 to descend, the lifting plate 335 drives the mounting cylinder 334 to descend, the mounting cylinder 334 drives the lifting block 333 to descend, the lifting block 333 drives the front plate 341 to descend, and the front plate 341 drives the cutting disc 365 to descend, so that the cutting disc 365 can cut the door frame parts, cutting two symmetrical 45-degree bevels, which is convenient for subsequent assembly. When a straight cut is required, the cutting angle can be changed.

[0041] Before cutting, the hydraulic rod 378 drives the U-shaped plate 374 to move up and down. The U-shaped plate 374 drives the inclined plate 372 to rotate. The inclined plate 372 drives the rear block 371 to move. Since the inclined plates 372 on both sides are symmetrically distributed, the rear blocks 371 on both sides move towards each other, which makes it easy to control the distance between the upright plates 331 on both sides and adjust the distance between the two cutting discs 365, making it convenient to cut door frame parts of various sizes.
