Description

Technical fields:

[0001] This utility model relates to the field of profile sawing technology, specifically to an adjustable-angle cutting saw. Background technology:

[0002] Sawing is an essential process in the door and window manufacturing industry. In a single sawing process, a double-headed saw is usually used to cut the profiles at a 45° angle. The existing double-headed saw has a relatively mature structure and working principle, and it is widely used in the industry. Its structure can be referenced from the double-headed saw cutting machine with automatic positioning function disclosed in Chinese patent (authorization announcement number: CN212599350U).

[0003] With the continuous development of the door and window industry, especially the vigorous development of the home decoration industry and sunrooms, more and more customized products are emerging. This places higher demands on the sawing and processing of profiles, requiring not only improved processing accuracy but also the ability to meet diverse corner cutting needs. To address this, various attempts have been made in existing technologies. For example, our company previously applied for a saw blade arc swing-type cutting device with variable cutting angle (authorization announcement number: CN213560265U), an integrated aluminum alloy blanking saw corner swing mechanism (authorization announcement number: CN214393207U), a corner swing positioning component and device for a double-head saw (authorization announcement number: CN219562382U), and an inner 45-degree precision special cutting saw head (authorization announcement number: CN220921104U). These technological improvements help to improve the processing accuracy of cutting saws. For example, Chinese patents disclose a CNC arbitrary angle double-head cutting saw (authorization announcement number: CN213857418U) and a CNC arbitrary angle double-head cutting saw machine for easy profile cutting (authorization announcement number: CN213702013U). These technological improvements provide a design concept for adjustable sawing angles. However, the application of the above technologies to cutting saws still has some shortcomings. For example, adjusting the sawing angle is too cumbersome or difficult to maintain effectively. Also, the design of the swing frame still adopts a fixed-angle sawing structure, which cannot match the requirements for arbitrary angle adjustment. This not only limits the angle adjustment range but may also cause interference between the swing frame and other components. Therefore, it is necessary to optimize and improve the existing cutting saw to make the overall structural design more reasonable, improve the sawing accuracy, and make the angle adjustment convenient and precise.

[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:

[0036] Example 1

[0037] like Figure 1-5 As shown, the adjustable-angle cutting saw includes a base 1. An RV reducer 2 is located at the rear end of the base 1. A motor 3, preferably a servo motor with a self-locking function, is located at the input end of the RV reducer 2. The output end of the motor is connected to an adjustable-angle frame 4. The other end of the adjustable-angle frame 4 is rotatably mounted on the base 1. An installation platform 5 is located on the upper end of the adjustable-angle frame 4. A guide rail 6 is longitudinally mounted on the installation platform 5 for transverse material feeding. A slider 7 is mounted on the guide rail 6, and a slide block 8 is mounted on the slider 7. A sawing mechanism 9 is mounted on the slide block 8. A feed driver 10 is longitudinally mounted at the rear end of the installation platform 5 and is connected to the slide block 8. The RV reducer 2 and motor 3 work together to adjust the rotation of the adjustable-angle frame 4, thereby achieving precise and rapid adjustment of the angle (i.e., adjustment of the cutting angle), and the self-locking function maintains the position.

[0038] The feed drive 10 includes a cylinder seat 1001 mounted on the mounting platform 5, a feed drive cylinder 1002 mounted on the cylinder seat 1001, and a fisheye connector 1003 connected to the piston rod of the feed drive cylinder 1002. A connecting rod 1004 connected to the fisheye connector 1003 is vertically mounted on the slide 8. A pneumatic linear drive is used to drive the saw blade to cut the profile.

[0039] The saw blade mechanism 9 includes a sawing support 903 mounted on the mounting platform 5. A sawing motor 904 and a sawing shaft 905 are mounted on the sawing support 903. A pulley A906 is mounted on the sawing motor 904. A saw blade B907 is mounted at one end of the sawing shaft 905, and a pulley B908 is mounted at the other end. Pulleys A906 and B908 are connected by a transmission belt 909. By using belt drive to rotate the saw blade, it provides good overload protection and vibration damping, making it suitable for processing profiles with high hardness or large dimensions.

[0040] The swing bracket 4 has a semi-circular front plate 11 at its front end, and an arc-shaped guide rail 12 on the rear end face of the semi-circular front plate 11. Two support seats 13 are horizontally spaced on the base 1, and support wheels 14 are rotatably mounted on the support seats 13. The arc-shaped guide rail 12 is placed on the two support wheels 14. A clamping bracket 15 is also provided on the support seats 13, and a clamping wheel 16 is rotatably mounted on the clamping bracket 15. The clamping wheel 16 is located on the inner side of the arc-shaped guide rail 12. By designing the semi-circular front plate 11, arc-shaped guide rail 12, support wheels 14, and clamping wheel 16, a shaftless rotational support (also called a virtual pivot support) is achieved, providing a larger rotational space and thus helping to improve the adjustment range of the swing angle.

[0041] The clamping bracket 15 is rotatably mounted on the support base 13. The clamping bracket 15 is provided with an adjustment mounting hole 17, and an adjustment screw 18 is provided on the adjustment mounting hole 17. The support base 13 is provided with an adjustment threaded hole 19, and the lower end of the adjustment screw 18 is provided on the adjustment threaded hole 19. This allows for adjustment of the position of the clamping roller 14, thereby adjusting the degree of clamping.

[0042] The front end of the swing bracket 4 is provided with a positioning groove 20, and the corresponding semi-circular front plate 11 is provided with an arc-shaped positioning protrusion 21. The positioning groove 20 and the arc-shaped positioning protrusion 21 cooperate to help the semi-circular front plate 11 be quickly and accurately assembled onto the swing bracket 4.

[0043] The semi-circular front plate 11 has a backing plate A22 on its front end surface, and the backing plate A22 has an avoidance opening A23 for the saw blade B907 to pass through. The design of the backing plate A22 not only positions the rear end of the profile, but also provides protection.

[0044] The base 1 is provided with a material support plate 28. When feeding the profile, the lower end of the profile is placed on the material support plate 28, and the rear end rests on the backing plate A22. Then, the profile is positioned and clamped by a clamp.

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 is that:

[0047] like Figure 6 As shown, the feed driver 10 includes a motor base 1005 mounted on a slide 8. A feed reducer 1006 is vertically mounted on the motor base 1005. The feed reducer 1006 has a feed motor 1007 at its input end and a feed gear 1008 at its output end. A feed rack 1009 is correspondingly mounted on the mounting platform 5, and the feed gear 1008 meshes with the feed rack 1009. The feed drive is achieved using a gear and rack transmission.

[0048] Example 3

[0049] The difference between this embodiment and embodiments 1 and 2 is that:

[0050] like Figure 7 As shown, the sawing mechanism 9 includes a spindle motor 901 horizontally mounted on the mounting platform 5, and a saw blade A902 is mounted on the spindle motor 901. The motor directly drives the saw blade to rotate, offering advantages such as simple structure, high transmission efficiency, and fast response speed.

[0051] Example 4

[0052] The difference between this embodiment and the above embodiments is that:

[0053] like Figure 8-9As shown, an L-shaped swing arm 24 is provided on the front end face of the swing frame 4. The L-shaped swing arm 24 is rotatably mounted on the base 1 via a rotating shaft 25. The L-shaped swing arm 24 can be integrally cast with the swing frame 4, eliminating the need for subsequent assembly. It has the advantages of high structural strength and simpler assembly.

[0054] The front end face of the swing bracket 4 is also provided with a backing plate B26, and the backing plate B26 has a clearance opening B27 for the saw blade to pass through. The design of the backing plate B26 not only positions the rear end of the profile, but also provides protection.

[0055] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0056] Any aspects of this utility model not described in detail are known to those skilled in the art.
