All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Please refer to Figure 1-7 , the present application provides a technical solution for a trimming device for magnesium alloy extrusion production: a trimming device for magnesium alloy extrusion production, including a chain drive roller conveyor 1, and a first gantry 3 is arranged on the upper surface of the chain drive roller conveyor 1.

[0023] Specifically, the chain drive roller conveyor 1 is mainly composed of a bracket, a drive roller and a chain drive assembly.

[0024] Second hydraulic cylinders 8 are arranged on both the front and rear sides of the first gantry 3. The telescopic ends of the second hydraulic cylinders 8 penetrate through the first gantry 3 and are connected to the mounting frame 9. A cutting motor 10 is arranged inside the mounting frame 9, and a cutting wheel 11 is arranged at the power output end of the cutting motor 10.

[0025] Specifically, the second hydraulic cylinders 8 are fixed to the first gantry 3 by bolts. The second hydraulic cylinders 8 drive the mounting frame 9, the cutting motor 10 and the cutting wheel 11 to move, so as to adjust the distance between the cutting wheel 11 and the magnesium alloy plate.

[0026] A guide and limit group 2 is arranged on one side of the first gantry 3, and the guide and limit group 2 is installed on the chain drive roller conveyor 1. The guide and limit group 2 is mainly composed of a screw adjustment group and a guide roller group.

[0027] On the other side of the first gantry 3, there is a second gantry 16. Inside the second gantry 16, it is connected to a third gantry 19 through a lifting group. Inside the third gantry 19, a bidirectional lead screw 20 is rotatably connected. One end of the bidirectional lead screw 20 passes through the third gantry 19 and is connected to a servo motor 22. The outer side of the bidirectional lead screw 20 is connected to a chamfering component through a lead screw nut, and a dust suction component is arranged at one end of the chamfering component.

[0028] Specifically, through the settings of the servo motor 22 and the bidirectional lead screw 20, the distance between the two chamfering components can be adjusted, so as to facilitate the chamfering treatment of magnesium alloy plates with different widths. And through the setting of the dust suction component, the waste chips generated by chamfering can be collected.

[0029] More specifically, two bearing seats are arranged in the middle of the bidirectional lead screw 20.

[0030] Further, the chamfering component mainly consists of a moving plate 23, a mounting seat 24, a housing 25, a chamfering motor 26, a driving bevel gear 27, a chamfering tool 28 and a driven bevel gear 29. The moving plate 23 is connected to the bidirectional lead screw 20 through a lead screw nut. A mounting seat 24 is arranged at the bottom of the moving plate 23. A housing 25 is arranged at the bottom of the mounting seat 24. Two driven bevel gears 29 are rotatably connected inside the housing 25, and the two driven bevel gears 29 are vertically meshed together. One end of the driven bevel gear 29 extends out of the housing 25 and is connected to the chamfering tool 28. One of the driven bevel gears 29 is meshed with the driving bevel gear 27, and one end of the driving bevel gear 27 extends out of the housing 25 and is connected to the chamfering motor 26.

[0031] Specifically, the two chamfering tools 28 are in a V shape (after clockwise rotation). The chamfering motor 26 drives the driving bevel gear 27 to rotate, so that the driving bevel gear 27 drives the driven bevel gear 29 to rotate, and then the two chamfering tools 28 rotate to chamfer the magnesium alloy plate.

[0032] Further, not less than three tool grooves are opened on the chamfering tool 28, and blades 30 are installed in the tool grooves. With this setting, by replacing the blades 30, the need to replace the entire chamfering tool 28 is avoided, thus reducing the maintenance cost.

The dust suction shell 31 is installed on the chamfering component through the extension plate, and a dust suction pipe 32 is arranged at one end of the dust suction shell 31.

A handwheel 15 is provided at one end of the screw rod 13, and the other end of the screw rod 13 is connected to the roller mounting seat. A guide roller 14 is provided inside the roller mounting seat.

[0036] Specifically, by rotating the handwheel 15, the handwheel 15 drives the screw rod 13 to rotate, thereby adjusting the position of the guide roller 14, so as to facilitate the guide roller 14 to guide the trimmed magnesium alloy sheet.

[0037] Further, the lifting group mainly consists of a third hydraulic cylinder 18 and two second guide rods 19. The third hydraulic cylinder 18 is provided on the upper surface of the second gantry 16. The telescopic end of the third hydraulic cylinder 18 is connected to the third gantry 19. Two second guide rods 19 are provided on the upper surface of the third gantry 19, and the second guide rods 19 are slidably connected to the second gantry 16.

[0038] Specifically, through the setting of the third hydraulic cylinder 18, it can drive the third gantry 19, the servo motor 2222, the bidirectional lead screw 20 and the chamfering assembly to move up and down, so as to facilitate the chamfering assembly to chamfer the magnesium alloy sheet. The setting of the second guide rod 19 can ensure the stability of the movement of the third gantry.

[0039] Further, a first hydraulic cylinder 6 is provided on the upper surface of the first gantry 3. The telescopic end of the first hydraulic cylinder 6 penetrates through the first gantry 3 and is connected to the connecting plate 4. Two first guide rods 7 are provided on the upper surface of the connecting plate 4, and the first guide rods 7 are slidably connected to the first gantry 3. The bottom of the connecting plate 4 is connected to two pressure rollers 5 through two pressure roller fixing plates.

[0040] Specifically, through the setting of the pressure rollers 5, the pressure rollers 5 can cooperate with the drive rollers on the chain-driven roller conveyor 1 to fixedly drive the magnesium alloy sheet, so as to avoid safety accidents caused by the shaking of the magnesium alloy sheet during the trimming process. Through the setting of the first hydraulic cylinder 6, it can drive the connecting plate 4, the first guide rods 7 and the pressure rollers 5 to move up and down, so as to be applicable to magnesium alloy sheets of different thicknesses.

[0041] During use: First, adjust the position of the guide roller set in the guide and limit set 2 through two screw adjustment groups, so as to conduct preliminary guiding and positioning on the magnesium alloy sheet; Secondly, drive the mounting frame 9, the cutting motor 10 and the cutting wheel 11 to move through two second hydraulic cylinders 8, so as to adjust the distance between the two cutting wheels 11 and the magnesium alloy sheet; Subsequently, rotate the two handwheels 15 in sequence, drive the screw 13 to rotate by the handwheel 15, so as to adjust the position of the guide roller 14, so as to facilitate the guiding of the magnesium alloy sheet after trimming by the guide roller 14; Subsequently, drive the bidirectional lead screw 20 to rotate by the servo motor 22, so that the two moving plates 23 move along the bidirectional lead screw 20, so that the moving plate 23 drives the mounting seat 24, the housing 25, the chamfering motor 26, the driving bevel gear 27, the chamfering tool 28 and the driven bevel gear 29 to move to a suitable position, so as to facilitate the trimming process of the magnesium alloy sheet.

[0042] Subsequently, start the chain-driven roller conveyor, the cutting motor 10 and the chamfering motor 26. The chain-driven roller conveyor conveys the magnesium alloy sheet, and conducts preliminary guiding and positioning on the magnesium alloy sheet through the guide and limit set 2. The cutting motor 1 drives the cutting wheel 11 to rotate to trim the magnesium alloy sheet. Subsequently, through the guiding and positioning of the guide roller 14, the chamfering motor 26 drives the driving bevel gear 27 to rotate, so that the driving bevel gear 27 drives the driven bevel gear 29 to rotate, so that the two chamfering tools 28 rotate to chamfer the magnesium alloy sheet. The waste chips produced by chamfering are collected by the dust collection component.
