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 an 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 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 action of 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, during conventional forward hot extrusion, the unit pressure at the interface between the tool and the ingot is very high, typically between 200 and 1200 MPa. This high pressure places high demands on the equipment and die materials, requiring not only high strength and rigidity but also high-temperature resistance. This increases equipment costs, and due to these harsh conditions, the extrusion tooling also experiences significant wear and tear. Prolonged use of the extrusion die in high-temperature and high-pressure environments presents multiple challenges, including increased risk of die damage, reduced product quality, decreased production efficiency, and increased safety hazards. Therefore, a series of countermeasures are needed to extend the life of the die, improve product quality and production efficiency, and reduce safety risks. Summary of the Invention

[0012] Beneficial effects of the present invention:

[0013] The ingot continuous extrusion production line described in the present invention has a structure that, when the hydraulic cylinder moves toward one end, first drives the collar away from the extrusion die, and then drives the extrusion die close to the barrel. By automatically separating the extrusion dies, the extrusion dies 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 dies. At the same time, separating the two extrusion dies can clean the metal debris, residue and oxide scale remaining inside them.

[0014] The ingot continuous extrusion production line described in the present invention adopts a structure that can drive the ring away from the extrusion die when the hydraulic cylinder moves toward the end close to the extrusion die, which facilitates the subsequent replacement of the extrusion die. Initially, the ring is sleeved on the outer surface of the extrusion die, thereby limiting the two extrusion dies so that they fit tightly together, preventing the two extrusion dies from loosening during the extrusion process. When the hydraulic cylinder moves toward the end away from the extrusion die, it drives the ring to sleeve on the outer surface of another set of extrusion dies.

[0015] The ingot continuous extrusion production line described in the present invention has a structure that, when the hydraulic cylinder moves toward the end away from the extrusion die, it will drive the round block to rotate half a circle. The round block rotates half a circle and then drives the barrels on both sides of the ring to rotate half a circle. The barrels on both sides of the ring rotate half a circle. When the barrels rotate half a circle, a new set of extrusion dies will be driven to fit together. The structure that is set can automatically replace the extrusion die. At the same time, when the barrels rotate, the metal debris, residue and oxide scale remaining inside the extrusion die will slide out. This can avoid the extrusion die from being used in a high temperature and high pressure environment for a long time, and at the same time, the metal debris, residue and oxide scale remaining inside the extrusion die can be cleaned.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figures 1-9 As shown, the ingot continuous extrusion production line described in the present invention includes a shell 100, and the upper end of the shell 100 is fixedly connected to a support block 200, and is characterized in that: two groups of extrusion dies 600 are arranged inside the shell 100, and one extrusion die 600 is divided into two halves and can be close to each other or far away from each other, and two complete extrusion dies 600 form a group, and a moving mechanism 300 for moving the extrusion die 600 is arranged inside the shell 100, and a limiting mechanism 400 for fixing the extrusion die 600 is arranged at one end of the shell 100 close to the moving mechanism 300, and a rotating mechanism 500 for replacing the extrusion die 600 is provided at one end of the support block 200.

[0029] Specifically, the moving mechanism 300 includes a hydraulic cylinder 301, which is mounted on the inner surface of the housing 100. One end of the output end of the hydraulic cylinder 301 is fixedly connected to a baffle 302. A first sleeve 303 is fixedly connected to the surface of the baffle 302. A sliding rod 304 is slidably connected to the interior of the first sleeve 303 and elastically connected through a spring. A first sliding block 305 is attached to one end of the sliding rod 304. A second sleeve 306 is sleeved on the outside of the first sliding block 305 and elastically connected through a spring. A barrel 307 is fixedly connected to the outer surface of the second sleeve 306. A steel wire rope 308 is fixedly connected to one end of the first sliding block 305. 8 is fitted with a rotating pin 309, both ends of which are rotatably connected to the drum 307, and one end of the steel wire rope 308 is fixedly connected to a second sliding block 310, which passes through the drum 307 and is slidably connected thereto; first, the heated blank is 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, and the hydraulic cylinder 301 is started to move toward one end close to the extrusion die 600, and the movement of the hydraulic cylinder 301 toward one end will drive the baffle 302 to move toward one end, and the movement of the baffle 302 toward one end will drive the first sleeve 303 to move toward one end, and the movement of the first sleeve 303 toward one end will drive The sliding rod 304 moves toward one end, and the sliding rod 304 moves toward one end, which drives the first sliding block 305 to move toward one end. The first sliding block 305 moves toward one end, which drives the wire rope 308 to move toward one end. The wire rope 308 moves toward one end, which drives the second sliding block 310 to move toward one end. The second sliding block 310 moves toward one end, which drives the extrusion die 600 close to the barrel 307. When the hydraulic cylinder 301 resets and moves toward the end away from the extrusion die 600, the spring inside the second sleeve 306 will reset. The spring inside the second sleeve 306 will reset and 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 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. At the same time, the two extrusion dies 600 can be separated to clean the metal debris, residue and oxide scale remaining inside them.

[0030] In addition, the limiting mechanism 400 includes a connecting rod 401, which is fixedly connected to the baffle 302, and a collar 402 is fixedly connected to one end of the connecting rod 401; when the baffle 302 moves toward one end, the connecting rod 401 is driven to move toward one end, and the connecting rod 401 is driven to move toward one end, and the collar 402 is driven to move toward one end, and the collar 402 moves away from the extrusion die 600 when it moves toward one end. When the hydraulic cylinder 301 is reset, the collar 402 is driven to reset, and the collar 402 is reset to be sleeved on the two extrusion dies 600. The surface of the extrusion die 600 is provided with a structure that 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 facilitates 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 tightly fitted together, preventing 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 drives the collar 402 to sleeve on the outer surface of another set of extrusion dies 600.

[0031] Furthermore, the rotating mechanism 500 includes a third sleeve 501, which passes through the support block 200 and is rotatably connected thereto, one end of the third sleeve 501 is fixedly connected to a round block 502, a first guide groove 5021 is provided inside the round block 502, a second guide groove 5022 is provided inside the round block 502, a rotating pin 503 is slidably connected inside the first guide groove 5021, one end of the rotating pin 503 is rotatably connected to the connecting block 504, a first sprocket 505 is fixedly connected to the surface of the third sleeve 501, one end of the first sprocket 505 is engaged with a chain 506, one end of the chain 506 is engaged with a second sprocket 507, and the second chain The center of the wheel 507 is fixedly connected to the outer surface of the second sleeve 306; when the collar 402 moves to one end, it also drives the connecting block 504 to move to one end, and the movement of the connecting block 504 to one end drives 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 slides from the second guide groove 5022 to the first guide groove 5021 and 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 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 high temperature and high pressure environments. By setting the structure in the hydraulic cylinder 301 When it moves toward the end away from the extrusion die 600, it will drive the block 502 to rotate half a circle. The rotation of the block 502 half a circle will in turn drive the barrels 307 on both sides of the ring 402 to rotate half a circle. The barrels 307 on both sides of the ring 402 will rotate half a circle. When the barrels 307 rotate half a circle, a new set of extrusion dies 600 will be fitted together. The set structure can automatically replace the extrusion die 600. At the same time, when the barrel 307 rotates, the metal debris, residue 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, residue and oxide scale remaining inside the extrusion die 600 can be cleaned.

[0032] It should be noted that a diversion hole 601 is opened inside the extrusion die 600 .

[0033] 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 and the collar 402 and passes through the third sleeve 501. It is then cooled and the hydraulic cylinder 301 is started to move toward one end close to the extrusion die 600. The movement of the hydraulic cylinder 301 to one end will drive the baffle 302 to one end. The movement of the baffle 302 to one end will drive the first sleeve 303 to one end. The movement of the first sleeve 303 to one end will drive the sliding rod 304 to one end. The movement of the sliding rod 304 to one end will drive the first sliding block 305 to one end. The movement of the first sliding block 305 to one end will drive the wire rope 308 to one end. The movement of the wire rope 308 to one end will drive the second sliding block 310 to one end. The movement of the second sliding block 310 to 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 When the second sliding block 310 is reset, 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. When the first sliding block 305 is reset, the pull on the wire rope 308 will be released. 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 provided, 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, when the two extrusion dies 600 are separated, the metal debris, residue and oxide scale remaining inside them can be cleaned.

[0034] When the hydraulic cylinder 301 moves toward the end away from the extrusion die 600, the collar 402 will be driven to be sleeved on the outer surface of the other set of extrusion dies 600.

[0035] When the collar 402 moves to one end, it also drives the connecting block 504 to move to one end. When the connecting block 504 moves to one end, it drives 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, and slides from the second guide groove 5022 to the third guide groove 5023 when the rotating pin 503 is reset. A 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 rotation of the third sleeve 501 drives the first sprocket 505 to rotate. The rotation of the first sprocket 505 drives the chain 506 to rotate. The rotation of the chain 506 drives the second sprocket 507 to rotate. The rotation of the second sprocket 507 drives the second sleeve 306 to rotate. The rotation of the second sleeve 306 drives the barrel 307 to rotate. The rotation of the barrel 307 drives 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, which drives the extrusion die 600 to rotate around the barrel 307. The rotation of the extrusion die 600 around the barrel 307 can regularly replace the extrusion die 600 to avoid long-term use in a high-temperature and high-pressure environment. Through the structure set, when the hydraulic cylinder 301 moves toward the end away from the extrusion die 600, it drives the round block 502 to rotate half a circle. The round block 502 rotates half a circle and then drives the barrels 307 on both sides of the ring 402 to rotate half a circle. The barrels 307 on both sides of the ring 402 rotate half a circle, and the half-circle rotation of the barrels 307 will 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, residue and oxide scale remaining inside the extrusion die 600 will slide out, so as to 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, residue and oxide scale remaining inside the extrusion die 600 can be cleaned.
