Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a rapid processing equipment for cutting door and window profiles. Background Technology

[0002] In the door and window manufacturing industry, profile cutting is a key processing step. Its processing quality and efficiency directly affect the overall production progress and product quality of doors and windows. With the rapid development of the construction industry, the market demand for doors and windows continues to rise, which in turn puts forward higher requirements for the cutting accuracy, processing speed and equipment adaptability of door and window profiles.

[0003] Patent application number CN202121008047.4 discloses a rapid cutting device for processing aluminum alloy door and window profiles. This solution can solve the problem of manually pulling the cutting mechanism to cut the profiles. However, this device lacks a protective device, which makes it easy for the cutting mechanism to generate sparks when cutting the profiles, potentially burning the operator. However, this solution still has the following problems: Traditional door and window profile cutting equipment has many limitations in practical applications. In terms of power transmission, most equipment uses a single reduction mechanism, which makes it difficult to accurately control the rotation speed and torque of the saw blade. This leads to speed fluctuations during the cutting process, which not only affects cutting efficiency but may also cause uneven profile cuts and reduce product qualification rate.

[0004] Regarding the stability of saw blade operation, the traditional equipment's rotating support structure design is not reasonable enough, and the saw blade is prone to shaking when rotating. This shaking is especially noticeable when cutting profiles made of harder materials, directly affecting the accuracy of the cutting dimensions and making it difficult to meet the needs of high-precision door and window processing.

[0005] In addition, the process of replacing saw blades in traditional equipment is cumbersome, often requiring the disassembly of multiple fixed parts, which takes a long time. When it is necessary to cut profiles of different specifications or materials, the equipment adjustment cycle is long, the flexibility is poor, and it cannot quickly adapt to diverse production needs.

[0006] In terms of safety performance, the braking systems of some equipment are slow to respond. When an emergency occurs requiring a quick stop of the saw blade rotation, they cannot brake quickly, posing a significant safety hazard and threatening the personal safety of operators. Furthermore, the overall structural stability of some equipment is insufficient. During long-term, high-frequency operation, components are prone to loosening and wear, which not only affects the equipment's lifespan but also increases maintenance costs and downtime, hindering the improvement of production efficiency.

[0007] Therefore, developing a door and window profile cutting equipment that can improve processing efficiency, ensure cutting accuracy, enhance operational flexibility and safety, and has a stable and reliable structure has become an urgent problem to be solved in the current door and window manufacturing industry.

A rotating base 13 is fixedly connected to the side of the rotating base boss 21 away from the main board 2. A saw blade mounting seat 15 is fixedly connected to the end of the rotating base 13 away from the rotating base boss 21. The saw blade mounting seat 15 is configured as a ring and has a saw blade mounting groove 24 on its surface. The bottom of the saw blade mounting groove 24 is provided with fixing holes 17, which are arranged in a ring. A ring saw blade 14 is fixedly connected inside the saw blade mounting groove 24. The ring saw blade 14 is replaced and fixedly installed by the mounting base at the bottom cooperating with the mounting holes 17. An annular brake disc 11 is fixedly connected to one end surface of the rotating base 13 away from the rotating base boss 21. The annular brake disc 11 has permanent magnet mounting holes 16 on its surface, and there are three permanent magnet mounting holes 16 distributed at 120 degrees. An inverted T-shaped permanent magnet 10 is fixedly connected inside the permanent magnet mounting hole 16, and a magnet blocking element 12 is fixedly connected to a section of the inverted T-shaped permanent magnet 10 near the upper surface of the annular brake disc 11. An electromagnet base 7 is fixedly connected to the inverted T-shaped permanent magnet 10 on the motherboard 2. An electromagnet 8 is fixedly connected to the end of the electromagnet base 7 away from the motherboard. A locking block 9 is fixedly connected to the end of the electromagnet 8 away from the electromagnet base 7. The locking block 9 is matched with the inverted T-shaped permanent magnet 10. The bottom of the motherboard 2 is fixedly connected to the rotating base boss 21 with a harmonic reducer mounting base 6.

A servo motor 3 is fixedly connected to one end of the planetary reducer 4 away from the main body 5 of the harmonic reducer, and the output end 23 of the servo motor is engaged with the planetary reducer 4.

[0026] Working principle: The operation of this rapid processing equipment for cutting door and window profiles relies on the coordinated linkage of various components to achieve efficient cutting of door and window profiles. When the equipment starts, the servo motor 3 provides power, and its output end 23 is engaged with the planetary reducer 4. After the power is initially reduced and increased in torque by the planetary reducer 4, it is transmitted to the harmonic reducer body 5. The output end 22 of the planetary reducer 4 is engaged with the harmonic reducer body 5, so that the power is further precisely reduced in the harmonic reducer body 5, ensuring the stability of the output speed and torque.

[0027] The power, after two-stage deceleration, is finally transmitted to the rotating base boss 21. Since the surface of the rotating base boss 21 is spline-shaped and fixedly connected to the inner ring 20 of the bearing, the rotating base boss 21 drives the rotating base 13 to rotate smoothly under the cooperation of the outer ring 18, roller 19 and inner ring 20 of the bearing.

[0028] When it is necessary to stop cutting or adjust the cutting angle, the electromagnet 8 starts to work. The electromagnet 8 fixed by the electromagnet seat 7 on the main board 2 generates magnetic force after being energized. It interacts with the inverted T-shaped permanent magnet 10 of the annular brake disc 11 on the rotating base 13. The locking block 9 cooperates with the inverted T-shaped permanent magnet 10 to achieve rapid braking with the help of magnetic force, so that the annular saw blade 14 stops rotating.

When it is necessary to cut door and window profiles of different specifications or materials, the appropriate ring saw blade 14 can be quickly replaced to adapt to diverse processing needs.

[0032] The braking system, consisting of the inverted T-shaped permanent magnet 10 on the annular brake disc 11, the electromagnet 8, and the locking block 9, can respond quickly when the equipment needs to stop, realizing emergency braking of the annular saw blade 14 and reducing safety hazards during operation.
