Aluminum alloy cutting machine

Abstract

This utility model relates to an aluminum alloy cutting machine. A blank is placed on a platform, and then a pushing mechanism is activated to advance the blank towards the cutting mechanism. When a certain length of blank needs to be cut, the blank is pulled away from the laser rangefinder by a moving plate. The cutting length is the sum of the moving distance of the rangefinder and the distance between the laser rangefinder and the cutting point of the cutting mechanism. The cutting mechanism then cuts the blank. When the cut blank needs to be discharged, the adsorption force of the adsorbent on the adsorbed part is first released, allowing the moving plate to rotate on the rangefinder via a reset component. Then, the pushing component is activated appropriately, causing the uncut blank to push the cut blank, which is then discharged from the platform via the moving plate. To better unload the cut blank, a discharge mechanism is activated, causing the cut blank to fall from the discharge mechanism.

Then the cutting mechanism is run to cut the billet.

Then the pushing component is run appropriately to make... The pushing component drives the uncut blank to push the cut blank, causing the cut blank to be discharged from the placement table through the moving plate. To better unload the cut blank, the discharge mechanism can be activated, causing the cut blank to fall from the discharge mechanism. After the cut blank is removed from the discharge mechanism, the reset component drives the moving plate to reset, and at the same time, the elastic component pulls the measuring plate to reset. Then, the adsorption component is activated, causing the adsorption component to absorb the adsorbed part, so that the moving plate stops rotating, which facilitates the subsequent distance cutting of blanks. This enables more convenient and efficient fixed-length cutting of aluminum alloy blanks, allowing aluminum alloy blanks to be continuously cut to a suitable length, thus better enabling the cut blanks to be used in subsequent applications.

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 to 7 As shown, an aluminum alloy cutting machine of this utility model includes a placement table 11, a cutting mechanism 19, a pushing mechanism, a discharging mechanism, and a length fixing mechanism 1. One end of the placement table 11 is provided with a first movable groove adapted to the cutting mechanism 19. The cutting mechanism 19 is movably connected to the inside of the first movable groove. The pushing mechanism is connected to the upper part of the placement table 11. The end of the placement table 11 away from the pushing mechanism is provided with a discharge port. The discharging mechanism is connected to the discharge port. The length fixing mechanism 1 is provided on the side of the first movable groove close to the discharging mechanism. The length fixing mechanism 1 is connected to the placement table 11.

[0030] The length-fixing mechanism 1 includes a distance measuring plate 101, a reset component, a moving plate 102, an elastic component 105, a laser rangefinder 106, an adsorption component 103, and an adsorbed component 104103. The placement platform 11 is provided with a second movable slot 2 adapted to the length-fixing mechanism 1. The distance measuring plate 101 is connected to the second movable slot 2 through a plurality of elastic components 105. The moving plate 102 is rotatably connected to the distance measuring plate 101 through the reset component. An adsorption component 103 is provided on the side of the distance measuring plate 101 near the first movable slot. An adsorbed component 104103 is provided on the side of the moving plate 102 near the adsorption component 103. The adsorption component 103 and the adsorbed component 104103 are detachably connected.

[0031] The working principle of this utility model is as follows: In actual production and use, when it is necessary to cut the aluminum alloy billet 10, the billet 10 can be placed on the placement platform 11, and then the pushing mechanism is run to push the billet 10 towards the cutting mechanism 19. When a certain length of billet 10 needs to be cut, the billet 10 pulls the measuring plate 101 away from the laser rangefinder 106 through the moving plate 102, so that the cutting length of the billet 10 is the sum of the moving distance of the measuring plate 101 and the cutting point distance between the laser rangefinder 106 and the cutting mechanism 19. Then the cutting mechanism 19 is run to cut the billet 10. When it is necessary to discharge the cut billet 10, the adsorption of the adsorbent 103 on the adsorbed part 104103 can be released first. Force is applied to make the moving plate 102 rotate on the measuring plate 101 via the reset member. Then, the pushing component is operated appropriately, causing the pushing component to push the uncut blank 10 onto the cut blank 10, so that the cut blank 10 is discharged from the placement table 11 through the moving plate 102. In order to better unload the cut blank 10, the discharge mechanism can be operated to make the cut blank 10 fall from the discharge mechanism. When the cut blank 10 is removed from the discharge mechanism, the reset member drives the moving plate 102 to reset. At the same time, the elastic member 105 pulls the measuring plate 101 to reset. Then, the adsorption member 103 is operated to absorb the adsorbed member 104103, so that the moving plate 102 stops rotating, which facilitates the subsequent distance cutting of the blank 10.

[0032] Furthermore, the discharge mechanism includes a first linear drive 18 and a discharge plate 17. One side of the discharge plate 17 is rotatably connected to the discharge port. The first linear drive 18 is disposed below the discharge plate 17. The lower part of the first linear drive 18 is rotatably connected to the bottom of the placement platform 11. The upper part of the first linear drive 18 is drivenly connected to the other side of the discharge plate 17. The first linear drive 18 is rotatably connected to the discharge plate 17.

[0033] As can be seen from the above description, when it is necessary to better discharge the cut blank 10 from the device, the first linear drive 18 can be operated, so that the first linear drive 18 drives one side of the unloading plate 17 to rotate at the discharge port, and the other side of the unloading plate 17 moves downward, so that the blank 10 located above the unloading plate 17 slides off the unloading plate 17 and is discharged.

[0034] Furthermore, the pushing mechanism includes a first rotation drive 7, a screw 3, a slider 8, and a push plate 9. The upper part of the placement platform 11 is provided with a sliding groove adapted to the slider 8. The slider 8 is slidably connected to the sliding groove. The screw 3 passes through one side of the slider 8 and is rotatably connected to the inside of the sliding groove. The push plate 9 is connected to the other side of the slider 8. The first rotation drive 7 is drivenly connected to the screw 3.

[0035] As can be seen from the above description, when it is necessary to push the aluminum alloy blank 10, the first rotation drive 7 can be operated, so that the first rotation drive 7 drives the slider 8 to move through the screw 3, thereby causing the slider 8 to drive the aluminum alloy blank 10 to move towards the cutting mechanism 19 through the push plate 9, and the cutting position of the blank 10 can be adaptively adjusted with the cooperation of the pushing mechanism and the fixed length mechanism 1.

[0036] Furthermore, the cutting mechanism 19 includes a second linear drive 1901, a rotating bracket 1902, a second rotating drive 1904, and a cutting disc 1903. The rotating bracket 1902 is slidably connected to the interior of the first movable groove. The cutting disc 1903 is rotatably connected to one side of the rotating bracket 1902. The second rotating drive 1904 is drivenly connected to the cutting disc 1903. The second linear drive 1901 is connected to the placement platform 11 and is linearly drivenly connected to the other side of the rotating bracket 1902.

[0037] As can be seen from the above description, once the cutting position of the blank 10 is determined, the second linear drive 1901 and the second rotary drive 1904 can be operated, so that the second linear drive 1901 drives the cutting disc 1903 to move towards the blank 10 through the rotating bracket 1902, thereby causing the second rotary drive 1904 to drive the cutting disc 1903 to rotate at high speed, so that the cutting disc 1903 cuts the blank 10.

[0038] Furthermore, it also includes an auxiliary holding mechanism, which includes a top holding mechanism and a side holding mechanism. The top holding mechanism is connected to the top of the placement platform 11, and the side holding mechanism is provided on the side of the placement platform 11 away from the fixed length mechanism 1.

[0039] Furthermore, the top-pressing holding mechanism includes a first bracket 6, a third linear drive member 4, a first slide rod 5, and a top-pressing plate 20. The first bracket 6 is fixedly connected to the top surface of the placement platform 11. The top-pressing plate 20 is slidably connected to the first bracket 6 through a plurality of first slide rods 5. The third linear drive member 4 is linearly driven connected to the top-pressing plate 20. The third linear drive member 4 is detachably connected to the first bracket 6.

[0040] Furthermore, the side-pressing mechanism includes a fourth linear drive member 13, a second bracket 15, a second slide rod 14, and a side pressure plate 12. The second bracket 15 is fixedly connected to the side of the placement platform 11 away from the fixed-length mechanism 1. The side pressure plate 12 is slidably connected to the second bracket 15 through a plurality of second slide rods 14. The fourth linear drive member 13 is linearly driven connected to the side pressure plate 12. The fourth linear drive member 13 is detachably connected to the second bracket 15.

[0041] As can be seen from the above description, after the cutting position of the blank 10 is adjusted, the third linear drive 4 and the fourth linear drive 13 can be operated, so that the third linear drive 4 and the fourth linear drive 13 can drive the top pressure plate 20 and the side pressure plate 12 to move towards the blank 10, thereby fixing the blank 10 with the cooperation of the placement table 11, the top pressure plate 20 and the side pressure plate 12, which facilitates subsequent cutting.

[0042] Furthermore, it also includes a PLC controller, which is electrically connected to the cutting mechanism 19, the pushing mechanism, the discharging mechanism, and the length-fixing mechanism 1, respectively.

[0043] As can be seen from the above description, it is beneficial to adjust the parameters of the aluminum alloy cutting machine through the PLC controller, and makes it more convenient for operators to operate the aluminum alloy cutting machine. Example 1
