[0002] With the development of modern machining industry, the requirements for cutting quality and precision are constantly increasing, as are the demands for improved production efficiency, reduced production costs, and highly intelligent automatic cutting functions. The development of CNC cutting machines must adapt to the requirements of modern machining industry. Cutting machines are categorized into circular saw cutting machines, plasma cutting machines, laser cutting machines, waterjet cutting machines, etc.

[0003] According to a public notice (Announcement No.: CN218611994U), the aforementioned application describes a high-speed circular saw for oblique angle cutting. It uses a clamping cylinder to hold the material to be cut, and an electric slider and an electric slide rail to transport the clamped material. The cutting saw teeth are rotated by a drive motor to complete the cutting of the material, thereby improving the cutting efficiency of the high-speed circular saw.

[0004] However, the clamping cylinder only clamps and fixes one side of the material. Under the high-speed cutting force of the circular saw, the unclamped cutting part loses effective restraint and is prone to splashing or irregular movement under the action of cutting impact force and centrifugal force, which can lead to accidental injury to workers.

[0005] The purpose of this invention is to provide a circular saw for oblique angle cutting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circular saw for oblique angle cutting, comprising a worktable, on the surface of which two sets of symmetrically arranged electric slide rails are fixedly connected, and electric sliders are provided on the surfaces of both sets of electric slide rails. A fixing assembly is provided between the two sets of electric sliders, and the fixing assembly includes a horizontal plate, which is fixedly connected to the surfaces of the two sets of electric sliders. A groove is formed on the surface of the horizontal plate, and two sets of symmetrically arranged movable seats are slidably connected inside the groove. A clamping cylinder is fixedly connected to the top of the movable seat, and a clamping end is provided at the opposite end of each of the two sets of clamping cylinders. An electric push rod is fixedly connected between the movable seat and the inner wall of the groove.

[0007] Preferably, a bracket is fixedly connected to the surface of the workbench, and a through groove is formed on the surface of the bracket. An adjustment component is provided inside the through groove. The adjustment component includes a mounting base, which is slidably connected inside the through groove. A through hole is formed on the side wall of the mounting base, and a lead screw is threaded into the through hole. The end of the lead screw is rotatably connected to the inner wall of the through groove. A bearing plate is fixedly connected to the bottom end of the mounting base. Two sets of symmetrically arranged side plates are fixedly connected to the bottom surface of the bearing plate. A second motor is hinged between the two sets of side plates through a hinge shaft. A saw blade is fixedly connected to the output shaft of the second motor.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a circular saw for oblique angle cutting, including a workbench 1, with four sets of symmetrically arranged support legs 11 fixedly connected to the bottom surface of the workbench 1, and two sets of symmetrically arranged electric slide rails 2 fixedly connected to the surface of the workbench 1. Electric sliders 21 are provided on the surface of both sets of electric slide rails 2, and a fixing component 3 is provided between the two sets of electric sliders 21. The electric slide rails 2 drive the electric sliders 21 to move, thereby driving the fixing component 3 and the workpiece to be smoothly conveyed towards the saw blade 58, realizing automated feeding.

[0022] The fixing component 3 includes a horizontal plate 31, which is fixedly connected to the surface of two sets of electric sliders 21. A groove 32 is formed on the surface of the horizontal plate 31, and two symmetrically arranged movable seats 33 are slidably connected inside the groove 32. A clamping cylinder 34 is fixedly connected to the top of each movable seat 33, and each clamping cylinder 34 has a clamping end 35 at one opposite end. An electric push rod 36 is fixedly connected between the movable seat 33 and the inner wall of the groove 32. The distance between the two sets of movable seats 33 is adjusted by the electric push rod 36 to accommodate the workpiece width. The two sets of clamping cylinders 34 drive the clamping ends 35 to clamp both sides of the workpiece, effectively preventing the unclamped cutting portion from splashing or moving irregularly during the cutting process due to loss of effective constraint, thus preventing injury to workers.

[0023] A support 4 is fixedly connected to the surface of the workbench 1. A through groove 41 is formed on the surface of the support 4. An adjustment component 5 is arranged inside the through groove 41. The adjustment component 5 includes a mounting base 51, which is slidably connected inside the through groove 41. A through hole is formed on the side wall of the mounting base 51, and a lead screw 52 is threaded into the through hole. The end of the lead screw 52 is rotatably connected to the inner wall of the through groove 41. A motor 53 is fixedly connected to the end of the support 4. The output shaft of the motor 53 is rotatably connected to the inner wall of the through groove 41 and is connected to the end of the lead screw 52. The mounting base 51 is fixedly connected to a bearing plate 54 at its bottom. Two sets of symmetrically arranged side plates 55 are fixedly connected to the bottom surface of the bearing plate 54. A second motor 57 is hinged between the two sets of side plates 55 through a hinge shaft 56. A saw blade 58 is fixedly connected to the output shaft of the second motor 57. The first motor 53 drives the lead screw 52 to rotate, which drives the mounting base 51 and the saw blade 58 to move laterally along the through groove 41, adjusting the lateral cutting position of the saw blade 58 and the workpiece. The second motor 57 drives the saw blade 58 to rotate at high speed, and the cutting action is completed in conjunction with the workpiece conveying.

[0024] The surface of the support plate 54 is provided with a mounting groove 59. A movable block 510 is slidably connected inside the mounting groove 59. A traction plate 511 is hinged to the bottom end of the movable block 510. The bottom end of the traction plate 511 is hinged to the end of the motor 57. A through hole is provided on the side wall of the movable block 510. A threaded rod 512 is threadedly connected to the through hole. The threaded rod 512 passes through and is rotatably connected to the end face of the support plate 54. One end of the threaded rod 512 is rotatably connected to the inner wall of the mounting groove 59. A rotating wheel 513 is fixedly connected to the other end of the threaded rod 512. An annular scale plate 514 is fixedly connected to the outer wall of the side plate 55. A ring 515 is fixedly connected to the outer wall of the hinge shaft 56. A pointer 516 is fixedly connected to the outer wall of the ring 515. Rotating the wheel 513 causes the threaded rod 512 to rotate, driving the movable block 510 to slide in the mounting groove 59. The traction plate 511 pulls the motor 57 to rotate around the hinge shaft 56, changing the tilt angle of the saw blade 58. The pointer 516, in conjunction with the annular scale plate 514, enables precise angle adjustment.

[0025] In this invention, during use, pre-processing and adjustment are first performed according to the size and specifications of the workpiece to be cut. The electric push rod 36 is activated, causing it to push the two sets of moving seats 33 to slide relative to or away from each other along the slide groove 32. The initial distance between the two sets of clamping ends 35 is adjusted to ensure that the distance is slightly greater than the width of the workpiece, so that the workpiece can be smoothly placed in. The workpiece is then placed stably on the surface of the horizontal plate 31, positioned between the two sets of clamping ends 35. Subsequently, the clamping cylinder 34 is controlled to drive the two sets of clamping ends 35 closer to the workpiece and tightly fit against its sides, completing the secure clamping of the workpiece and preventing loosening or displacement of the workpiece during the cutting process.

[0026] Next, adjust the lateral position and tilt angle of the saw blade 58 according to the cutting requirements. If the lateral cutting position needs to be adjusted, start motor 53. The output shaft of motor 53 drives the lead screw 52 to rotate in the through groove 41. Since the mounting base 51 is threadedly connected to the lead screw 52 and its sliding is restricted in the through groove 41, the rotation of the lead screw 52 will be converted into the lateral movement of the mounting base 51, which in turn drives the bearing plate 54, motor 57 and saw blade 58 to move synchronously until the saw blade 58 is aligned with the preset lateral cutting position on the workpiece, and then turn off motor 53.

[0027] For tilt angle adjustment, the operator rotates the rotary wheel 513, which drives the threaded rod 512 to rotate within the mounting groove 59. The movable block 510, threadedly connected to the threaded rod 512, slides linearly along the mounting groove 59. The sliding of the movable block 510 is transmitted to the second motor 57 via the traction plate 511, causing the second motor 57 to rotate around the hinge shaft 56. The saw blade 58 rotates synchronously with the second motor 57, and the tilt angle gradually changes. During this process, the hinge shaft 56 drives the ring 515 and the pointer 516 to rotate. The operator observes the mark pointed to by the pointer 516 on the annular scale plate 514 to precisely adjust to the required cutting angle. After adjustment, the operator stops rotating the rotary wheel 513.

[0028] Once everything is ready, start motor 57. The output shaft of motor 57 drives saw blade 58 to rotate at high speed. After saw blade 58 reaches a stable operating speed, start electric slide rail 2. Electric slide rail 2 drives electric slider 21 to move along the length of the slide rail towards saw blade 58. Fixing component 3 and the clamped workpiece are synchronously and smoothly conveyed with electric slider 21. When the workpiece contacts the high-speed rotating saw blade 58, saw blade 58 cuts the workpiece at an oblique angle. During the cutting process, because the workpiece is tightly fixed at clamping end 35 and the cutting part is always in a constrained state, the risk of splashing or irregular movement is effectively avoided.

[0029] After cutting, first control the electric slide rail 2 to drive the electric slider 21 to move in the opposite direction, so that the workpiece is separated from the saw blade 58 and reset. Then turn off the motor 2 57. After the saw blade 58 has completely stopped rotating, the clamping cylinder 34 controls the clamping end 35 to release the workpiece, and the operator can then remove the cut workpiece. If the next cut is required, simply repeat the above clamping, adjustment, cutting, and removal steps.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
