Description

Technical fields:

[0001] This utility model relates to the field of profile processing technology, specifically to a high-efficiency sawing device suitable for milling and sawing machining centers. Background technology:

[0002] A milling and sawing machining center refers to CNC machining equipment capable of performing milling and sawing processes on profiles. The working principles and structural layouts of existing milling and sawing machining centers are relatively mature. Existing milling and sawing machining centers generally employ arbitrary angle sawing structures for sawing, such as the arbitrary angle sawing mechanism disclosed in our previously filed application for an intelligent laser milling and sawing center for aluminum profiles (authorization announcement number: CN221313230U). Using an arbitrary angle sawing structure to saw profiles can meet diverse cutting angle requirements, and only one sawing unit is needed, resulting in low overall cost.

[0003] After the aforementioned arbitrary angle sawing structure was applied in milling and sawing machining centers for a period of time, deep-seated technical problems were discovered. In actual applications, users still most frequently use 90°, 45°, and 135° sawing angles. 90° sawing is mainly used to trim the ends of the entire profile to improve processing accuracy, while other angles are customized sawing processes and are less frequently used in daily operations. Therefore, in actual work, the saw blade needs to frequently switch between 45° and 135° sawing angles. This not only accelerates the wear of parts but also affects processing efficiency as the profile waits for angle switching. Furthermore, frequent angle switching, especially after prolonged use and wear, increases the rotational angle error, affecting processing quality. Therefore, it is necessary to optimize and improve the sawing structure in milling and sawing machining centers to improve sawing efficiency and quality while meeting diverse cutting angle requirements.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content:

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide a high-efficiency sawing device suitable for milling and sawing machining centers. It has the advantages of reasonable structural design, taking into account sawing efficiency and diverse cutting angle requirements, extending equipment service life and improving processing efficiency.

[0006] The present invention achieves the above objectives by adopting the following technical solutions:

[0007] A high-efficiency sawing device suitable for milling and sawing machining centers includes a frame with a feed channel arranged laterally on the frame. A fixed-angle sawing mechanism and an arbitrary-angle sawing mechanism are arranged sequentially on the frame along the profile feeding direction. The fixed-angle sawing mechanism is located at the front end of the frame, and the arbitrary-angle sawing mechanism is located at the upper end of the frame. The fixed-angle sawing mechanism saws the profile from bottom to top, and the arbitrary-angle sawing mechanism saws the profile from top to bottom.

[0008] The fixed angle sawing mechanism includes a vertical plate mounted on a frame, a guide rail A vertically mounted on the vertical plate, a slider A mounted on the guide rail A, a slide plate A mounted on the slider A, a motor base A mounted on the slide plate A, a sawing motor A mounted at a 45° angle on the motor base A, a saw blade A mounted on the sawing motor A, a lead screw A mounted on the slide plate A and a lead screw nut A, and a lead screw A mounted on the lead screw nut A. The two ends of the lead screw A are rotatably mounted via bearings A, and a synchronous pulley A is mounted on the upper end of the lead screw A. A drive motor base A is mounted on the vertical plate, and a drive motor A is mounted on the drive motor base A. A synchronous pulley B is mounted on the output shaft of the drive motor A, and the synchronous pulley A and the synchronous pulley B are connected by a synchronous belt.

[0009] The frame is equipped with a sawing and guiding mechanism, which includes a guide seat mounted on the frame, a guide rail mounted vertically on the guide seat, a guide slider mounted on the guide rail, a guide bracket mounted on the guide slider, a lifting drive cylinder mounted vertically on the guide seat, the lifting drive cylinder being connected to the guide bracket, a guide plate mounted on the guide bracket, and an avoidance groove mounted on the guide plate.

[0010] The arbitrary angle sawing mechanism includes a stand, on which a guide rail B is vertically mounted. A slide B is mounted on the guide rail B. A lead screw seat B and a lead screw nut B are located on the back of the slide B. A lead screw B is mounted on the lead screw nut B. The lower end of the lead screw B is rotatably mounted via a bearing B. The upper end of the lead screw B is mounted on a motor mount. A drive motor B is mounted on the motor mount. The drive motor B is connected to the lead screw B via a coupling. A rotary mounting seat is located in front of the slide B. An RV reducer is mounted on the rotary mounting seat. A servo motor is located at the input end of the RV reducer, and a rotary seat is located at the output end. A sawing motor B is mounted on the rotary seat. A pulley A is mounted on the output shaft of the sawing motor B. A rotating shaft is rotatably mounted on the rotary seat. A saw blade B is located at one end of the rotating shaft, and a pulley B is located at the other end. The pulley A and pulley B are connected by a conveyor belt.

[0011] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0012] A combination of fixed-angle and arbitrary-angle sawing mechanisms is used to meet the sawing requirements of the milling and sawing machining center. The fixed-angle sawing mechanism can handle 45° sawing, while the arbitrary-angle sawing mechanism primarily performs 135° sawing. Without needing to adjust the arbitrary-angle sawing mechanism, it can meet the most commonly used 45° and 135° cutting angle requirements, thus improving sawing efficiency. When custom cutting angles are required, the angle of the arbitrary-angle sawing mechanism can be adjusted. The entire sawing structure balances diverse cutting angle needs with processing efficiency. Attached image description:

Detailed implementation method:

[0021] Furthermore, the terms “horizontal,” “vertical,” “A,” “B,” etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] like Figure 1-4 As shown, a high-efficiency sawing device suitable for milling and sawing machining centers includes a frame 1. A feed channel 2 is laterally provided on the frame 1. A fixed-angle sawing mechanism 3 and an arbitrary-angle sawing mechanism 4 are sequentially arranged on the frame 1 along the feed direction of the profile 6. The fixed-angle sawing mechanism 3 is located at the front end of the frame 1, and the arbitrary-angle sawing mechanism 4 is located at the upper end of the frame 1. The fixed-angle sawing mechanism 3 saws the profile 6 from bottom to top, and the arbitrary-angle sawing mechanism 4 saws the profile 6 from top to bottom. The fixed-angle sawing mechanism 3 and the arbitrary-angle sawing mechanism 4 work together to meet the sawing requirements of milling and sawing machining centers. The fixed-angle sawing mechanism 3 can perform 45° sawing, while the arbitrary-angle sawing mechanism 4 mainly performs 135° sawing. Without needing to adjust the arbitrary-angle sawing mechanism, it can meet the processing requirements of the most commonly used 45° and 135° cutting angles, thus helping to improve sawing efficiency. When custom cutting angle processing is required, the angle of the arbitrary-angle sawing mechanism 4 can be adjusted for sawing. The entire sawing structure takes into account both diverse cutting angle requirements and processing efficiency.

[0024] The fixed angle sawing mechanism 3 includes a vertical plate 301 mounted on a frame. A guide rail A302 is vertically mounted on the vertical plate 301. A slider A303 is mounted on the guide rail A302. A sliding plate A304 is mounted on the slider A303. A motor base A305 is mounted on the sliding plate A304.

A wire nut seat A308 and a wire nut A308 are mounted on the sliding plate A304. 309, the lead screw A310 is provided on the lead screw nut A309, and the two ends of the lead screw A310 are respectively rotatably set through bearings A311.

The output shaft of the drive motor A314 is provided with a synchronous pulley B315. The synchronous pulley A312 and the synchronous pulley B315 are connected by a synchronous belt 316. The specific structure of the fixed sawing mechanism 3 is given. The vertical feed saw blade A307 is driven by synchronous belt drive and ball screw drive to achieve sawing of the profile at a 45° angle.

[0025] The frame 1 is equipped with a sawing guide mechanism 5, which includes a guide seat 501 mounted on the frame 1, a guide rail 502 vertically mounted on the guide seat 501, a guide slider 503 mounted on the guide rail 502, a guide bracket 504 mounted on the guide slider 503, and a lifting drive cylinder 505 vertically mounted on the guide seat 501. The lifting drive cylinder 505 is connected to the guide bracket 504, and a guide plate 506 is mounted on the guide bracket 504. The guide plate 506 has an avoidance groove 507. In actual sawing, there will be scrap material (i.e., sawn waste material). The scrap material can easily collide with the saw blade A307. By designing the sawing guide mechanism 5, the scrap material can be effectively prevented from contacting the saw blade A307, thus protecting the saw blade A307. At the same time, in order to avoid interference between the guide plate 506 and the saw blade B418, the lifting mechanism can also be adjusted.

[0026] The arbitrary angle sawing mechanism 4 includes a stand 401, on which a guide rail B402 is vertically mounted. A slide B403 is mounted on the guide rail B402. A lead screw seat B404 and a lead screw nut B405 are located on the back of the slide B403. A lead screw B406 is mounted on the lead screw nut B405. The lower end of the lead screw B406 is rotatably mounted via a bearing B407. The upper end of the lead screw B406 is mounted on a motor housing 408. A drive motor B409 is mounted on the motor housing 408. The drive motor B409 is connected to the lead screw B406 via a coupling 410. A rotating mounting base 411 is provided in front of the slide block B403. An RV reducer 412 is mounted on the rotating mounting base 411. A servo motor 413 is located at the input end of the RV reducer 412, and a rotating base 414 is located at the output end. A sawing motor B415 is mounted on the rotating base 414. A pulley A416 is mounted on the output shaft of the sawing motor B415. A rotating shaft 417 is rotatably mounted on the rotating base 414.
