Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting saw equipment technology, and in particular to a CNC rotatable angle cutting saw equipment. Background Technology
[0002] In the large-scale production of lightweight wall materials such as lightweight cement products and gypsum board, band saw cutting equipment serves as a primary processing unit, widely used for horizontal or vertical cutting of the board blanks. Existing band saw cutting machines typically use upper and lower pulleys of fixed diameter to determine the cutting thickness. If a change in cutting thickness is needed, the machine must be stopped to replace pulleys of different diameters, which is both time-consuming and labor-intensive. Furthermore, multiple sets of pulleys of different specifications must be kept on-site, increasing inventory and management costs. In addition, existing equipment almost exclusively cuts within a single plane, unable to achieve rapid switching between multiple angles, irregular shapes, or multiple faces within the same process. When encountering irregular shape processing requirements, manual positioning or manual flipping of the workpiece is often necessary, affecting production cycle time and easily causing positioning errors.
[0003] The manual or semi-automatic adjustment mechanisms of traditional band saws are no longer sufficient to meet the demands of continuous and precise production. The lack of seamless integration between cutting parameters and centralized control systems such as touchscreens and PLCs prevents one-click programming or centralized monitoring, resulting in significant manual intervention in the production process. Especially under high-speed or heavy-load cutting conditions, the single-end support of most band saw wheels easily leads to vibration and swaying, further exacerbating cutting deviations. Furthermore, the lack of reliable positioning and support structures on the conveyor table can cause shaking or shifting during loading and unloading, affecting cutting accuracy and yield.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0030] The present invention will now be further described in conjunction with the accompanying drawings and embodiments: Figure 1-6 The CNC rotatable angle cutting saw shown includes a main frame 1, a conveyor frame 2, a column 3 and a rotating lifting frame 4. The column 3 and the conveyor frame 2 are fixed on the main frame 1. The rotating lifting frame 4 is slidably connected to the column 3 via a slider 31. The conveyor frame 2 is equipped with a rotating transfer car 21, and the rotating transfer car 21 is equipped with a cutting die bottom 22. A band saw 5 is installed on the rotating lifting frame 4.
[0031] The rotating lifting frame 4 can slide and lift on the column 3, and can be used with positioning pins or CNC rotating mechanisms to achieve free rotation within a range of ±90° (or larger angles), allowing for quick switching between horizontal and vertical cutting on the same equipment; the rotating transfer carriage 21 on the conveyor frame 2 is equipped with the cutting die base 22, which can automatically complete the transfer and precise positioning of the workpiece before and after cutting, without the need for manual flipping or repositioning; the rotating lifting frame 4 slides smoothly on the guide rail of the column 3 via the slider 31, in conjunction with the lifting drive; it maintains extremely low vibration during lifting and cutting, ensuring the accuracy of the band saw 5 cutting trajectory, and the finished product size error can be controlled within the range of ±0.2 mm.
[0032] As an embodiment of this utility model, the rotating lifting frame 4 is provided with a band saw mounting frame 41, and the band saw 5 is fixed on the band saw mounting frame 41; the rotating lifting frame 4 is provided with a mounting positioning plate 42, and the mounting positioning plate 41 is provided with a passive rotating shaft 43 and a positioning hole 44; the passive rotating shaft 43 is connected to the saw rotating bearing 45, and the saw rotating bearing 45 is connected to the saw rotating motor 6.
[0033] Furthermore, the band saw 5 includes a saw blade 51, a saw drive wheel 52, a saw driven wheel 53, and a saw motor 54. The saw motor 54 is connected to the saw drive wheel 52, and the saw blade 51 is located on the outside of the saw drive wheel 52 and the saw driven wheel 53. The saw motor 54 is fixed on a motor mounting plate 46, and the motor mounting plate 46 is fixed on one side of the rotating lifting frame 4.
[0034] The saw motor 54 is directly connected to the saw drive wheel 52, which transmits power directly to the saw blade 51. The saw motor 54 is fixed to the special motor mounting plate 46, which is rigidly connected to the rotating lifting frame 4, so that the drive shaft and the driven wheel frame are coaxial.
[0035] In one embodiment of this utility model, the slider 31 includes an active mounting plate 311, a slider mounting plate 312, and a rotary motor mounting plate 313. The slider mounting plate 312 is disposed on both sides of the active mounting plate 311 and the rotary motor mounting plate 313. The slider mounting plate 312 is mounted on the lifting rail 35. The saw rotary motor 6 is fixed on the rotary motor mounting plate 313. The saw rotary motor 6 moves up and down with the slider and maintains the same movement as the rotary lifting frame 4.
[0036] The saw rotary motor 6 is fixed on the rotary motor mounting plate 313 and moves up and down on the lifting rail 35 along with the slider 31, ensuring that the motor and saw wheel always maintain a fixed relative position. This ensures that the power output is synchronized with the cutting position, improving the consistency of the cutting path. The synchronous movement of the motor with the slider reduces the use of flexible couplings, universal joints, or long cables, avoiding torque attenuation and signal delay in long-stroke power transmission, and improving drive response speed and cutting efficiency.
[0037] Furthermore, the active mounting plate 311 is provided with a positioning pin 314, the position of which corresponds to the positioning hole 44, and the positioning hole 44 is used to position the cutting angle of the positioning pin 314.
[0038] Positioning pins 314 and positioning holes 44 correspond one-to-one. When the pin is inserted into the hole, the angle is locked, avoiding errors caused by manual reading or fine-tuning during the adjustment process and ensuring high-precision positioning of the selected cutting angle. Each time the same positioning hole is switched, the same angle setting can be achieved without secondary calibration, improving the repeatability and consistency of batch irregular or multi-angle cutting. The mechanical limiting structure forms a rigid lock during the cutting process, effectively preventing angle drift under vibration or impact, and avoiding the risk of miscutting or workpiece damage caused by loosening.
[0039] In one embodiment of this utility model, there are two columns 3, which are located on the left and right sides of the rotating lifting frame 4. A lifting chain 32 is provided inside the column 3. The lifting chain 3 is connected to the lifting sprocket shaft 33, which is connected to the lifting motor 34. The lifting chain 32 is connected to the slider 31, so that the slider mounting plate 312 moves up and down on the lifting track 35.
[0040] In one embodiment of this utility model, the rotating transfer vehicle 21 includes a rotating frame 211, a rotating shaft 212, a support wheel 213, and a rotating cylinder. The blank 6 to be cut is placed on the rotating frame. The rotating frame 211 is connected to the rotating shaft 212, the support wheel 213 is mounted on the rotating frame 211, and the rotating shaft 212 is connected to the rotating cylinder. A bottom-feeding baffle 23 is also provided on the rotating frame 211, and the bottom-feeding baffle 23 is connected to a baffle cylinder. The support wheel 213 assists in rotation, providing stable support during rotation, and the bottom-feeding baffle fixes the rotating frame, providing cutting stability.
[0041] The rotary cylinder 212 drives the rotary shaft 212, which in turn drives the rotary frame 211 to flip the workpiece without manual intervention. The flipping action is fast and stable. The support wheel 213 bears part of the workpiece weight during rotation, reducing the radial load and frictional resistance of the rotary shaft, extending the life of the cylinder and bearings, and making the flipping smoother. The bottom baffle 23, under the action of the baffle cylinder, is pressed tightly against the bottom of the rotary frame to mechanically lock the workpiece, effectively preventing the workpiece from shifting or tilting during cutting and ensuring cutting accuracy.
[0042] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
