Description

Technical Field

[0001] The present invention belongs to the technical field of door and window processing, and in particular relates to a cutting device for processing aluminum alloy door and window frames. Background Art

[0002] In the field of aluminum alloy door and window processing, cutting accuracy and efficiency are of vital importance. Traditional cutting devices have many shortcomings, such as large manual operation errors and low degree of automation, which lead to inaccurate cutting dimensions, affecting the assembly accuracy and overall quality of doors and windows; low cutting efficiency, which makes it difficult to meet the needs of mass production; and imperfect safety protection measures, which pose safety hazards. At the same time, traditional devices have poor adaptability to aluminum alloy profiles of different specifications and shapes, and require frequent adjustments, which increases production costs and time costs. Common aluminum alloy cutting devices on the market often only have cutting capabilities in two directions of 45 degrees or 90 degrees, and can only cut one aluminum alloy at a time. Sometimes different angles are required for aluminum alloy cutting to meet personalized market needs. How to design an aluminum alloy cutting device that can adapt to different angles and can process different angles at the same time is the problem that the present invention needs to solve.

The adjusting handle 601 is rotated to realize the movement of the movable plate 603.

[0020] The cutting mechanism 3 includes a connecting rod 302, one end of which is fixedly connected to a transparent protective cover 301. This serves as a protective cover when the cutting disc 304 is cutting, and also allows the cutting status to be observed during cutting. The other end is fixedly connected to a rotating shaft 306, which is rotatably connected to the rotating shaft limit 108. The rotating shaft limit 109 is rotatably connected to the hydraulic expansion device 2 305. The extended end of the hydraulic expansion device 2 305 is rotatably connected to the connecting rod 302.

[0021] Those skilled in the art can use existing technologies they know, such as installing corresponding mechanical limit switches or photoelectric sensors to limit the specified positions of each actuator during the following action process; in order to achieve automated operation, the present invention can use numerical control technology or PLC to control the action of each actuator.

[0022] Working process: Preparation work, the hydraulic telescopic device 202 is stretched, driving the clamping plate 203 away from the boss; the hydraulic telescopic device 401 contracts, driving the clamping plate 2 407 into the slot 1 403, and the bolt 4091 is pushed outward by the convex shaft 405, separating the clamping plate 3 408 from the clamping plate 2 407.

[0023] After preparations are complete, the aluminum alloy to be cut at 90 degrees is placed between clamping plate 1 203 and the boss, and between clamping plate 2 407 and clamping plate 3 408. Hydraulic expansion joint 1 202 contracts, clamping plate 1 203 clamps the aluminum alloy. Hydraulic expansion joint 3 401 stretches, and clamping plates 2 407 and 3 408 clamp the aluminum alloy with springs 4092. Once clamping is complete, press and hold control button 103. Drive mechanism 303 rotates cutting disc 304, and hydraulic expansion joint 2 305 stretches, rotating connecting rod 302 and slowly bringing cutting disc 304 closer to the aluminum alloy, allowing it to be cut. During cutting, transparent protective cover 301 protects the operator and allows the operator to see the cutting progress. Chips generated by the cutting fall into chip chute 105 and flow out through chip discharge port 110. When the cutting is completed, the hydraulic expansion device 2 305 contracts, driving the connecting rod 302 to rise, controlling the hydraulic expansion device 1 202 and the hydraulic expansion device 3 401 on both sides to release the aluminum alloy.

[0024] When it is necessary to perform a 45-degree cut on the aluminum alloy, the aluminum alloy only needs to be placed in the same manner as when cutting at 90 degrees. Turn the adjustment handle 601 to engage the gear 1 605 and the gear 2 606 with the gear disc 1 208 and the gear disc 2 414, respectively. The disc motor 209 rotates, driving the turntable 1 201 to rotate. The gear disc 1 208 on the turntable 1 201 drives the gear 1 605 to rotate. The gear 1 605 drives the gear 2 606 to rotate. The gear 2 606 drives the gear disc 2 414 to rotate, so that the turntable 2 402 rotates synchronously with the turntable 1 201. At the same time, the hydraulic telescopic device 3 401 drives the clamping plate 2 407 and the clamping plate 3 408 to move forward synchronously, so that the aluminum alloy on the first rotating mechanism 2 and the second rotating mechanism 4 will not be deformed and always maintain a straight line. When the indicator arrow 1 206 and the indicator arrow 2 413 both point to 45 degrees on the scale nameplate 106, press the control button 103 to cut the aluminum alloy.

[0025] When cutting two aluminum alloys simultaneously at different angles, first place one aluminum alloy on the second rotating mechanism 4 and clamp it. Activate the hydraulic expansion mechanism 3 401 to push the clamped aluminum alloy aside. Then, place the other aluminum alloy on the first rotating mechanism 2 and clamp it. Turn the adjustment handle 601 so that Gear 1 605, Gear 2 606, and Gear 3 607 are not in contact with Sprocket 1 208 and Sprocket 2 414. Hold Handle 1 205 and Handle 2 406 with both hands, respectively, and rotate Turntable 1 201 and Turntable 2 402. Release the handles when the indicator arrows 1 206 and 2 413 reach the desired angle. Press the control button 103 to initiate the cut.

[0026] When the first rotating mechanism 2 and the second rotating mechanism 4 need to be locked and not rotated, it is only necessary to rotate the adjustment handle 601 so that the gear three 607 engages with the sprocket one 208 and the sprocket two 414. Then the first rotating mechanism 2 and the second rotating mechanism 4 will not rotate, and are suitable for being fixed at a certain angle for long-term use.

[0027] Finally, although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
