Abstract
Description
Technical Field
[0001] The invention relates to the technical field of continuous ingot extrusion, in particular to a continuous ingot extrusion production line. Background Art
[0002] The ingot continuous extrusion production line is a highly efficient metal processing production line, which is mainly used to produce non-ferrous metal ingots. The working principle of the ingot continuous extrusion production line is mainly based on the continuous extrusion technology. This technology forms an extrusion cavity between the extrusion wheel and the solidification shoe. The liquid metal flows into the extrusion cavity from the guide tube. Under the friction between the extrusion wheel groove and the billet, the liquid metal undergoes dynamic crystallization and deformation in the extrusion cavity, and is finally squeezed out of the die hole to form an ingot.
[0003] However, in the conventional forward hot extrusion process, the unit pressure of the contact surface between the tool and the ingot is very high, generally between 200 and 1200 MPa. This high pressure places high demands on the materials of the equipment and the mold, requiring not only high strength and rigidity, but also high temperature resistance, which leads to an increase in equipment costs. In addition, due to such harsh conditions, the loss of the extrusion tool is also very large. The long-term use of the extrusion die in a high temperature and high pressure environment will face many challenges such as increased risk of mold damage, reduced product quality, reduced production efficiency, and increased safety hazards. Therefore, a series of countermeasures need to be taken to extend the service life of the mold, improve product quality and production efficiency, and reduce safety risks. Summary of the invention

At this time, the inside of the barrel 307 The spring will drive the second sliding block 310 to reset, and the second sliding block 310 will slide outward when it resets, which will make the two extrusion dies 600 fit tightly together. The elastic force of the spring inside the first sleeve 303 is greater than the elastic force of the spring inside the second sleeve 306. Through the structure set, when the hydraulic cylinder 301 moves to one end, it will first drive the driving ring 402 away from the extrusion die 600, and then drive the extrusion die 600 close to the barrel 307. By automatically separating the extrusion dies 600, the extrusion die 600 can be prevented from being in a high temperature and high pressure environment for a long time, thereby improving the service life of the extrusion die.

Initially, the ring 402 is sleeved on the outer surface of the extrusion die 600, thereby limiting the position of the two extrusion dies so that they are tightly fitted together to prevent the two extrusion dies from loosening during the extrusion process. When the hydraulic cylinder 301 moves toward the end away from the extrusion die 600, the ring 402 is driven to sleeve on the outer surface of another group of extrusion dies 600.

The first guide groove 5021 gradually increases in depth along the direction of movement of the blank, and the second guide groove 5022 gradually decreases in depth along the direction of movement of the blank. The rotating pin 503 slides from the first guide groove 5021 to the second guide groove 5022. When the rotating pin 503 is reset, it will slide from the second guide groove 5022 to the first guide groove 5021 and drive the round block 502 to rotate half a circle. The rotation of the round block 502 half a circle will drive the third sleeve 501 to rotate The rotation of the third sleeve 501 will drive the first sprocket 505 to rotate, the rotation of the first sprocket 505 will drive the chain 506 to rotate, the rotation of the chain 506 will drive the second sprocket 507 to rotate, the rotation of the second sprocket 507 will drive the second sleeve 306 to rotate, the rotation of the second sleeve 306 will drive the barrel 307 to rotate, the rotation of the barrel 307 will drive the second sliding block 310 to rotate around the barrel 307, the rotation of the second sliding block 310 around the barrel 307 will drive the extrusion die 600 to rotate around the barrel 307, the extrusion die 600 rotates around the barrel 307, and the extrusion die 600 can be replaced regularly to avoid long-term use in a high temperature and high pressure environment.

[0021] It should be noted that a diversion hole 601 is opened inside the extrusion die 600 .
[0022] Working principle: When the present invention is in use, the heated blank is first driven to move by the extrusion wheel. The blank passes through the extrusion die 600, the collar 402 passes through the third sleeve 501, and then is cooled. The hydraulic cylinder 301 is started to move toward one end close to the extrusion die 600. The movement of the hydraulic cylinder 301 toward one end will drive the baffle 302 to move toward one end. The movement of the baffle 302 toward one end will drive the first sleeve 303 to move toward one end. The movement of the first sleeve 303 toward one end will drive the sliding rod 304 to move toward one end. The movement of the sliding rod 304 toward one end will drive the first sliding block 305 to move toward one end. The movement of the first sliding block 305 toward one end will drive the wire rope 308 to move toward one end. The movement of the wire rope 308 toward one end will drive the second sliding block 310 to move toward one end. The movement of the second sliding block 310 toward one end will drive the extrusion die 600 close to the barrel 307. When the hydraulic cylinder 301 is reset to move toward the end away from the extrusion die 600, the second The spring inside the sleeve 306 will reset, and the spring reset inside the second sleeve 306 will drive the first sliding block 305 to reset. The reset of the first sliding block 305 will release the pull on the wire rope 308. At this time, the spring inside the barrel 307 will drive the second sliding block 310 to reset. The second sliding block 310 will reset and slide outward to fit the two extrusion dies 600 tightly together. The elastic force of the spring inside the first sleeve 303 is greater than the elastic force of the spring inside the second sleeve 306. Through the structure set, when the hydraulic cylinder 301 moves to one end, it will first drive the driving ring 402 away from the extrusion die 600, and then drive the extrusion die 600 close to the barrel 307. By automatically separating the extrusion die 600, the extrusion die 600 can be prevented from being in a high temperature and high pressure environment for a long time, thereby improving the service life of the extrusion die. At the same time, the two extrusion dies 600 can be separated to clean the metal debris, residue and oxide scale remaining inside.
[0023] When the baffle 302 moves toward one end, it will drive the connecting rod 401 to move toward one end. When the connecting rod 401 moves toward one end, it will drive the collar 402 to move toward one end. When the collar 402 moves toward one end, it will move away from the extrusion die 600. When the hydraulic cylinder 301 is reset, it will drive the collar 402 to reset. When the collar 402 is reset, it will be sleeved on the surfaces of the two extrusion dies 600. The structure set can drive the collar 402 away from the extrusion die 600 when the hydraulic cylinder 301 moves toward the end close to the extrusion die 600, which is convenient for the subsequent replacement of the extrusion die 600. Initially, the collar 402 is sleeved on the outer surface of the extrusion die 600, thereby limiting the two extrusion dies so that they are closely fitted together to prevent the two extrusion dies from loosening during the extrusion process. When the hydraulic cylinder 301 moves toward the end away from the extrusion die 600, it will drive the collar 402 to sleeve on the outer surface of another group of extrusion dies 600.
[0024] When the sleeve ring 402 moves to one end, it will also drive the connecting block 504 to move to one end. When the connecting block 504 moves to one end, it will drive the rotating pin 503 to move to one end. The first guide groove 5021 gradually increases in depth along the direction of movement of the blank, and the second guide groove 5022 gradually decreases in depth along the direction of movement of the blank. The rotating pin 503 slides from the first guide groove 5021 to the second guide groove 5022. When the rotating pin 503 is reset, it will slide to the second guide groove 5022. The guide groove 5021 drives the round block 502 to rotate half a circle, the round block 502 rotates half a circle to drive the third sleeve 501 to rotate, the third sleeve 501 rotates to drive the first sprocket 505 to rotate, the first sprocket 505 rotates to drive the chain 506 to rotate, the chain 506 rotates to drive the second sprocket 507 to rotate, the second sprocket 507 rotates to drive the second sleeve 306 to rotate, the second sleeve 306 rotates to drive the barrel 307 to rotate, the barrel 307 rotates to drive the second sliding block 310 to rotate around the circle The barrel 307 rotates, and the second sliding block 310 rotates around the barrel 307 to drive the extrusion die 600 to rotate around the barrel 307. The extrusion die 600 rotates around the barrel 307 so that the extrusion die 600 can be replaced regularly to avoid long-term use in a high temperature and high pressure environment. The structure is set so that when the hydraulic cylinder 301 moves toward the end away from the extrusion die 600, the round block 502 will rotate half a circle. The round block 502 rotates half a circle, which in turn drives the barrels 307 on both sides of the collar 402 to rotate half a circle. The barrels 307 on both sides of the ring 402 rotate half a circle, and the barrels 307 rotate half a circle to drive a new set of extrusion dies 600 to fit together. The set structure can automatically replace the extrusion die 600. At the same time, when the barrels 307 rotate, the metal debris, residues and oxide scale remaining inside the extrusion die 600 will slide out. This can avoid the extrusion die 600 from being used in a high temperature and high pressure environment for a long time, and at the same time, the metal debris, residues and oxide scale remaining inside the extrusion die 600 can be cleaned.
