Description

Technical Field

[0001] The present application relates to the field of wire drawing machine pay-off coils, and in particular to a brake device for a wire drawing machine pay-off coil. Background Art

[0002] Magnesium alloy wire drawing machine is a kind of equipment specially used for processing magnesium alloy. Through continuous stretching, magnesium alloy is made into thin wire or wire material to enhance its mechanical properties.

[0003] When using a magnesium alloy wire drawing machine, the magnesium alloy is unwound through a reel. When the wire drawing machine stops working, the rotation of the reel is stopped by a brake device. When some existing brake devices are in use, the brake pad is pressed onto the rotating reel. The braking effect of this type is relatively poor. When the brake pad contacts the reel, the reel has to rotate for a while before it stops, which reduces the practicality of the device. In addition, when the brake pad contacts the reel, the brake pad will generate high temperature. If the brake pad is not cooled, the brake pad may be damaged due to the high temperature, which reduces the service life of the brake pad. Utility Model Content

At this time, the output shaft of the bidirectional motor drives the bidirectional screw rod to rotate forward, further making the two sleeves and the two circular plates move in opposite directions, and the two sleeves drive the two brakes through the two L-shaped rods. The plates move toward each other, further causing the two brake plates to clamp the outer surface of the rotating rod, reducing the rotation speed of the rotating rod, and further reducing the rotation speed of the reel.

The first gear and the second gear can engage with each other. When the slide plate moves to the top, the first gear and the second gear engage together to fix the position of the second gear, further fixing the position of the reel, completing the braking operation on the reel.

Therefore, the present application is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, as Figures 1 to 6 As shown, the present application provides a wire reel brake device for a magnesium alloy wire drawing machine, the device comprising:

[0031] Bracket 1;

[0032] The reel 2 is arranged on both sides of the bracket 1, and a rotating rod 201 is fixedly provided at one end of the reel 2. When the reel 2 rotates, the rotating rod 201 is driven to rotate;

[0033] The bidirectional screw rod 202 is provided on both sides of the inner wall of the bracket 1 through bearings, and the outer surface of the bidirectional screw rod 202 is provided with two sleeves 203, and the outer surface of the bidirectional screw rod 202 has two threads with different rotation directions. The two sleeves 203 and the two threads with different rotation directions on the outer surface of the bidirectional screw rod 202 are connected together;

[0034] Two L-shaped rods 204 are fixedly mounted on the outer surfaces of the two sleeves 203, and brake pads 205 are fixedly mounted on opposite ends of the two L-shaped rods 204. The two sleeves 203 drive the two brake pads 205 to move toward each other through the two L-shaped rods 204, further causing the two brake pads 205 to clamp the outer surface of the rotating rod 201, thereby reducing the rotation speed of the rotating rod 201 and further reducing the rotation speed of the reel 2;

[0035] The cylinder 206 is fixedly mounted on one side of the bracket 1 , and an air guide tube 208 is disposed on the outer surface of the cylinder 206 .

[0036] like Figures 1 to 6 As shown, a hollow cylinder 209 is fixedly provided at one end of the air guide tube 208, and a slide plate 210 is movably embedded in the inner wall of the hollow cylinder 209. A return spring 211 is fixedly provided on one side of the slide plate 210, and one side of the return spring 211 is fixedly provided on the inner wall of one side of the hollow cylinder 209. The two sleeves 203 are slidably provided on one side of the inner wall of the bracket 1.

The return spring 211 has elastic force. When the slide plate 210 is not squeezed by the gas, the elastic force of the return spring 211 pulls the slide plate 210 to return to its original position, and further resets the first gear 213 through the cross bar 212.

[0037] like Figures 1 to 6 As shown, a cross bar 212 is fixedly provided on one side of the skateboard 210, and a first gear 213 is fixedly provided on one end of the cross bar 212. A second gear 214 is fixedly provided on the outer surface of the rotating rod 201. A bidirectional motor 215 is installed on one side of the bracket 1. The output shaft of the bidirectional motor 215 is connected to one side of the bidirectional screw rod 202. The first gear 213 and the second gear 214 can engage with each other. When the skateboard 210 moves to the top, the first gear 213 and the second gear 214 engage together to fix the position of the second gear 214, and further fix the position of the reel 2 through the rotating rod 201 to prevent the reel 2 from continuing to rotate. Turn on the external power switch of the bidirectional motor 215, and the output shaft of the bidirectional motor 215 can rotate forward and reverse. The output shaft of the bidirectional motor 215 drives the bidirectional screw rod 202 to rotate.

[0038] like Figures 1 to 6As shown, a water tank 3 is fixedly provided on one side of the bracket 1 , a first connecting pipe 302 is installed on one side of the water tank 3 , and cooling water is inside the water tank 3 .

[0039] like Figures 1 to 6 As shown, a delivery pump 303 is installed at one end of the first connecting pipe 302, and a second connecting pipe 304 is installed at the output end of the delivery pump 303. When the external power switch of the delivery pump 303 is turned on, suction is generated at the input end of the delivery pump 303, and the water inside the water tank 3 is discharged into the interior of the second connecting pipe 304 through the first connecting pipe 302.

[0040] like Figures 1 to 6 As shown, a drain pipe 305 is installed at one end of the second connecting pipe 304, and a plurality of water outlet holes are opened on the outer surface of the drain pipe 305. The internal cooling water discharged into the second connecting pipe 304 is further discharged into the drain pipe 305, and is sprayed onto the two brake pads 205 through the plurality of water outlet holes on the drain pipe 305 to cool the brake pads 205.

[0041] like Figures 1 to 6 As shown, two guide plates 301 are fixedly provided on both sides of the inner wall of the bracket 1 . The two guide plates 301 are tiltedly provided on the inner wall of the inner side of the bracket 1 . The cooled water flows into the interior of the water tank 3 through the two guide plates 301 .

[0042] like Figures 1 to 6 As shown, the outer surface of the bidirectional screw 202 is threadedly sleeved with two circular plates 207, and the two circular plates 207 are movably embedded in the inner wall of the cylinder 206. The two circular plates 207 are connected to two different rotation direction thread lines on the outer surface of the bidirectional screw 202. The two circular plates 207 can slide on the inner wall of the cylinder 206, and the two circular plates 207 move in opposite directions to squeeze the gas inside the cylinder 206.

[0043] Working principle: When using the wire drawing machine to pay off the magnesium alloy, the magnesium alloy is paid off through the rotating reel 2. When braking, the external power switch of the bidirectional motor 215 is turned on, and the output shaft of the bidirectional motor 215 can rotate forward and reverse. The output shaft of the bidirectional motor 215 is controlled to rotate forward. The two sleeves 203 can slide on one side of the inner wall of the bracket 1, and the two circular plates 207 can slide on the inner wall of the cylinder 206. Then, when the bidirectional screw rod 202 rotates, the two sleeves 203 and the two circular plates 207 do not rotate together with the bidirectional screw rod 202, further making the two sleeves 203 and the two circular plates 207 outside the bidirectional screw rod 202. The surfaces move in opposite or opposite directions. At this time, the output shaft of the bidirectional motor 215 drives the bidirectional screw rod 202 to rotate forward, further causing the two sleeves 203 and the two circular plates 207 to move in opposite directions. The two sleeves 203 drive the two brake pads 205 to move in opposite directions through the two L-shaped rods 204, further causing the two brake pads 205 to clamp the outer surface of the rotating rod 201, reducing the rotation speed of the rotating rod 201, and further reducing the rotation speed of the reel 2. The two circular plates 207 move in opposite directions, squeezing the gas inside the cylinder 206. The gas enters the interior of the hollow cylinder 209 through the air guide pipe 208, and the slide plate 210 can be in the hollow cylinder 209. The slide plate 210 is pushed by the gas and drives the first gear 213 to move through the cross bar 212. The first gear 213 and the second gear 214 can mesh with each other. When the slide plate 210 moves to the top, the first gear 213 and the second gear 214 mesh together to fix the position of the second gear 214, further fixing the position of the reel 2, completing the braking operation of the reel 2. When the brake device is used to brake the reel 2, the braking effect is better, preventing the reel 2 from continuing to rotate, and improving the practicality of the device. When the brake device is started, there is cooling water inside the water tank 3, and the delivery pump 30 is turned on. 3, and the external power switch of the delivery pump 303 generates suction at the input end, and the water in the water tank 3 is discharged into the second connecting pipe 304 through the first connecting pipe 302, and further discharged into the drain pipe 305. The water is sprayed onto the two brake pads 205 through multiple water outlet holes on the drain pipe 305 to cool the brake pads 205. The cooled water flows into the interior of the water tank 3 through the two guide plates 301 and is reused. Therefore, when the brake device is used, the two brake pads 205 are cooled, thereby preventing the two brake pads 205 from being damaged due to high temperature and increasing the service life of the two brake pads 205.
