[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention discloses an aluminum-magnesium alloy extrusion device, including a test platform 1. A clamping device 2 and an extrusion device 3 are arranged at the top end of the test platform 1, and the extrusion device 3 is located above the clamping device 2.

[0023] The clamping device 2 includes a placing plate 201. Driving boxes 206 are slidably connected to both sides of the placing plate 201 through storage boxes 205. The inner wall of the driving box 206 is rotatably connected to a turntable 207 through a built-in motor. An elliptical sleeve 209 is arranged at the top end of the turntable 207. A follow-up column 208 is fixedly connected to the top end of the turntable 207. The follow-up column 208 is located inside the elliptical sleeve 209 and is slidably connected to the inner wall of the elliptical sleeve 209. The outer side of the elliptical sleeve 209 is hinged to a clamping plate 212 through an extension rod 211, and the clamping plate 212 is located above the placing plate 201.

[0024] By setting the clamping device 2, the built-in motor turntable 207 in the driving box 206 is used to drive the follow-up column 208 to drive the elliptical sleeve 209 to slide horizontally, so that the elliptical sleeve 209 can drive the clamping plate 212 to gradually fit the aluminum-magnesium alloy block through the extension rod 211, so that the two clamping plates 212 can fix the aluminum-magnesium alloy block on the placing plate 201. Compared with the comparative solution, the clamping effect of the clamping device 2 on the aluminum-magnesium alloy block is more stable, and the clamping effect of the aluminum-magnesium alloy block is significantly improved.

[0025] The extrusion device 3 includes a support frame 301. A hydraulic cylinder 302 is fixedly installed at the top end of the support frame 301. The movable end of the hydraulic cylinder 302 is fixedly connected to an extrusion plate 303, and the extrusion plate 303 is located above the placing plate 201.

[0026] Specifically, a telescopic sleeve rod 202 is provided at the top of the test platform 1, and a support bar 203 is fixedly connected between the tops of two telescopic sleeve rods 202 on the same side. A chute is opened at the bottom end of the placement plate 201, and the support bar 203 is located on the inner wall of the chute.

[0027] In this embodiment, the support bar 203 can be used to complete the splicing combination between the telescopic sleeve rod 202 and the placement plate 201, and the placement plate 201 can be movably connected to the test platform 1 through the telescopic sleeve rod 202, so that the placement plate 201 can be replaced after long-term use.

[0028] Specifically, a slide bar 210 is fixedly connected to the inner wall of the drive box 206, and the side end of the elliptical collar 209 is slidably connected to the surface of the slide bar 210.

[0029] In this embodiment, the elliptical collar 209 slides along the slide bar 210, thereby improving the movement stability of the elliptical collar 209.

[0030] Specifically, a contact wheel is rotatably connected to the bottom end of the clamping plate 212, and the clamping plate 212 is lapped with the top end of the placement plate 201 through the contact wheel.

[0031] In this embodiment, the contact wheel can be used to form a movable contact between the clamping plate 212 and the placement plate 201, thereby improving the movement stability of the clamping plate 212.

[0032] Specifically, a pressure sensor 204 is provided at the top of the test platform 1, the top end of the pressure sensor 204 is movably clamped with the bottom end of the placement plate 201, and a distance sensor is provided on the side surface of the pressing plate 303.

[0033] In this embodiment, the infrared distance sensor can monitor the distance between the pressing plate 303 and the placement plate 201, and the pressure sensor 204 monitors the pressure received by the aluminum-magnesium alloy block.

[0034] In use, first place the magnesium alloy-aluminum alloy chopsticks on the placement plate 201, and then start the built-in motor inside the drive box 206, so that the output shaft of the built-in motor drives the turntable 207 to rotate. The rotation of the turntable 207 will drive the follower post 208 to perform circular motion. Since the follower post 208 is located inside the elliptical collar 209 and is slidably connected to the inner wall of the elliptical collar 209, the relative position of the follower post 208 will change on the inner wall of the elliptical collar 209. The movement of the follower post 208 will drive the elliptical collar 209 to slide horizontally, causing the elliptical collar 209 to drive the clamping plate 212 to slide on the top of the placement plate 201 through the extension rod 211, so that the two clamping plates 212 can gradually fit the magnesium alloy-aluminum alloy block, and the two clamping plates 212 can fix the magnesium alloy-aluminum alloy block on the placement plate 201.

[0035] Subsequently, start the extrusion device 3, so that the movable end of the hydraulic cylinder 302 drives the extrusion plate 303 to move downward along the direction of the support frame 301, so that the extrusion plate 303 starts to extrude the magnesium alloy-aluminum alloy block on the placement plate 201.

[0036] The infrared distance sensor can monitor the distance between the extrusion plate 303 and the placement plate 201, and the pressure sensor 204 monitors the pressure received by the aluminum-magnesium alloy block. If the monitoring distance of the infrared distance sensor changes, the maximum pressure received by the aluminum-magnesium alloy block can be detected, making the use effect of the test device better and facilitating people's use.

[0037] In summary, for this aluminum-magnesium alloy extrusion device, by setting the clamping device 2, the built-in motor turntable 207 inside the drive box 206 is used to drive the follower post 208 to drive the elliptical collar 209 to slide horizontally, so that the elliptical collar 209 drives the clamping plate 212 to gradually fit the magnesium alloy-aluminum alloy block through the extension rod 211, and the two clamping plates 212 can fix the magnesium alloy-aluminum alloy block on the placement plate 201. Compared with the comparative scheme, the clamping effect of the clamping device 2 on the aluminum-magnesium alloy block is more stable, and the clamping effect of the magnesium alloy-aluminum alloy block is significantly improved.
