[0033] The present invention will be further described below by way of non-limiting embodiments and in conjunction with the accompanying drawings: Example 1

[0034] As attached Figures 1-12As shown, an angle steel beveling machine includes a first angle steel beveling unit 1 and a second angle steel beveling unit 2 sequentially arranged along the feeding direction. The two angle steel beveling units have the same structure, and the two angle steel beveling units are arranged in opposite directions. Taking the first angle steel beveling unit 1 as an example, the specific structure of the angle steel beveling unit is described, which includes a base 1.1, a frame, a beveling die, a beveling cylinder 1.7, a beveling die rotating mechanism, and a beveling die moving mechanism. The base 1.1 is welded with section steel and steel plates, and the frame includes two vertical plates 1.2 fixedly arranged on the base 1.1, and a workbench 1.4 arranged between the two vertical plates 1.2. The workbench 1.4 is fixedly connected to the vertical plates 1.2 on both sides, and the workbench 1.4 is tilted. In this embodiment, the tilt angle of the workbench 1.4 is 45°. A working opening 1.20 is provided on each of the two vertical plates 1.2. Two support blocks 1.19 arranged in a V shape are provided at the working opening 1.20. The two support blocks 1.19 are used to support the angle steel workpiece. The angle cutting die rotating mechanism includes a base plate 1.5, a rotating gear 1.13, a rotating disk 1.12, a rotating motor reducer 1.3, and a driving gear 1.16. The rotating gear 1.13 is disposed on the upper portion of the base plate 1.5 and includes an inner ring and an outer ring with a gear. The inner ring of the rotating gear 1.13 is fixedly connected to the base plate 1.5. The rotating disk 1.12 is disposed on the upper portion of the rotating gear 1.13 and is fixedly connected to the outer ring of the rotating gear 1.13. The rotating motor reducer 1.3 is fixed to the lower portion of the base plate 1.5. The output shaft of the rotating motor reducer 1.3 passes through the base plate 1.5 and is connected to the driving gear 1.16 located on the upper portion of the base plate 1.5. The driving gear 1.16 meshes with the outer ring of the rotating gear 1.13. The rotating motor reducer 1.3 drives the driving gear 1.16 to rotate, which in turn drives the outer ring of the rotating gear 1.13 to rotate through gear meshing transmission, thereby driving the rotating disk 1.12 to rotate. The bottom of the base plate 1.5 is provided with a slider, which slides onto a slide rail 1.14 provided on the upper portion of the worktable 1.4. One end of the base plate 1.5 is connected to a mechanism for moving the corner cutting mold, which drives the base plate 1.5 along the slide rail 1.14. In this embodiment, the mechanism for moving the corner cutting mold includes a traverse servo motor 1.6 and a ball screw 1.15 connected to the output shaft of the traverse servo motor 1.6. The traverse servo motor 1.6 is fixed to the frame, and the other end of the ball screw 1.15 is connected to one end of the base plate 1.5 via a nut. The corner cutting mold is set on the turntable 1.12. The corner cutting mold includes an upper knife seat 1.10 and a lower knife 1.24 for installing an upper knife 1.23. An upper knife seat guide seat 1.17 is fixed on the turntable 1.12. The upper knife seat 1.10 is movably set up and down in the upper knife seat guide seat 1.17. The turntable 1.12 also serves as a lower knife seat, and the lower knife 1.24 is installed on the turntable 1.12.The angle cutting cylinder 1.7 is fixedly mounted on the frame via a mounting plate 1.8, with the axis of the angle cutting cylinder 1.7 perpendicular to the worktable 1.4. The lower end of the piston rod of the angle cutting cylinder 1.7 is connected to a pressure head 1.9, the lower end of which is provided with a guide groove 1.21. The guide groove 1.21 is a T-shaped guide groove. The upper end of the upper tool holder 1.10 of the angle cutting die can rotatably slide with the guide groove 1.21 at the lower end of the pressure head 1.9. When the angle cutting die moving mechanism drives the base plate 1.5 to move along the slide rail 1.14, it also drives the angle cutting die to move, and the upper end of the upper tool holder 1.10 of the angle cutting die moves along the guide groove 1.21. When the turntable 1.12 drives the angle cutting die to rotate, the upper end of the upper tool holder 1.10 of the angle cutting die rotates within the guide groove 1.21. To facilitate the rotation of the upper tool holder 1.10 of the angle cutting die, the upper end of the upper tool holder 1.10 of the angle cutting die is preferably a rotating shaft 1.22 with a T-shaped cylindrical structure. The upper tool holder 1.10 of the angle cutting die cooperates with the guide groove 1.21 at the lower end of the pressure head 1.9 through its T-shaped cylindrical structure rotating shaft 1.22. To ensure the reliability of the piston rod of the angle cutting cylinder when driving the pressure head 1.9 to move, a pressure head guide seat 1.18 is fixedly installed between the two side vertical plates of the frame. The pressure head 1.9 slides with the pressure head guide seat 1.18 and is guided by the pressure head guide seat 1.18 when the pressure head 1.9 moves. To fix the workpiece, a fixing device for fixing the workpiece is provided on the outside of at least one of the angle steel cutting units. The workpiece can be fixed by the fixing device during angle steel processing. The fixing device for fixing the workpiece can be provided on both the feed side and the discharge side of the angle steel cutting machine as needed. The fixing device for fixing the workpiece can adopt any fixing structure in the prior art. For example, a material supporting mechanism can be set at the bottom, and a material pressing mechanism driven by a cylinder or oil cylinder can be used to fix the workpiece at the top. Taking into account the simplicity and reliability of the structural design, in this embodiment, the fixing device for fixing the workpiece preferably adopts an electromagnetic material suction device 3. The electromagnetic material suction device 3 is arranged on the outside of the angle steel cutting unit, corresponding to the working port arrangement on the vertical plate. The electromagnetic material suction device 3 includes an electromagnetic material suction cylinder 3.1 and an electromagnet 3.4. The electromagnetic material suction cylinder 3.1 is vertically fixed on the base 1.1, and the electromagnet 3.4 is connected to the upper end of the piston rod of the electromagnetic material suction cylinder 3.1 through a bracket 3.2. In order to ensure the reliability of the electromagnet when moving up and down, a guide rail 3.3 is fixed on the outside of the vertical plate 1.2 of the angle steel cutting unit, and the bracket 3.2 slides with the guide rail 3.3 through a slider. After the electromagnet 3.4 is energized, it can suck the angle steel workpiece by the magnetic force generated.

[0035] The drawings of this embodiment only show that the electromagnetic material suction device 3 is set on the outside of one of the angle steel chamfering units. According to processing requirements, one set of electromagnetic material suction device 3 can be set on the feeding side and the discharging side of the angle steel chamfering machine.

[0036] When the present invention is working, the angle steel workpiece 1.11 is placed with its opening facing upwards, and the angle steel workpiece is sucked and positioned by the electromagnetic suction device 3. The cutting cylinder 1.7 is the power source, and the piston rod of the cutting cylinder 1.7 drives the upper knife of the cutting die downward, and cooperates with the lower knife installed on the turntable 1.12 to perform the cutting process of the angle steel. The two angle steel cutting units can respectively perform cutting process on the two limbs of the angle steel workpiece. The cutting die rotating mechanism can drive the cutting die to rotate, and the cutting die can rotate to different angles to cut the angle steel limbs at different angles, thereby realizing arbitrary angle shearing of the limbs on both sides of the angle steel. The cutting die moving mechanism can drive the cutting die rotating mechanism and the cutting die to move along the slide rail on the worktable to avoid other components in the processing process.

[0037] The other parts of this embodiment are all existing technologies and will not be described in detail here. Example 2

[0038] As attached Figures 1-14 As shown, an angle steel processing device includes a feed channel 5 and an angle steel chamfering machine 4, which are arranged in sequence. A feed trolley 6 is provided on the feed channel 5. Both the feed channel 5 and the feed trolley 6 are conventional. The feed trolley 6 is provided with a clamp that can clamp the angle steel workpiece along the feed channel 5 for CNC-controlled feeding. The structure of the angle steel chamfering machine 4 in this embodiment is the same as that of the angle steel chamfering machine in Example 1.

[0039] This angle steel processing equipment enables automated angle cutting. The angle steel is placed with its opening facing upward on a feed channel 5 and then fed into the angle cutting machine 4 by a feed trolley 6 for automatic cutting. The cutting die movement mechanism of the angle cutting machine 4 drives the entire rotating mechanism to move, allowing it to avoid the clamp.
