Background
The small R extrusion finishing machine is specially designed for machining coiled pipes in the boiler industry and is suitable for manufacturing the coiled pipes of low, medium and high pressure boilers.

The specific working process and principle of the patent are as follows:
The initial state of the extrusion finishing machine is that the left extrusion oil cylinder 204 and the right extrusion oil cylinder 204 are in a piston rod withdrawing state, and the left extrusion mechanism 2 and the right extrusion mechanism 3 are far away from a working area; the left and right extrusion cushion block cylinders 205 are in a piston rod retraction state; the left and right extrusion lift cylinders 207 are in a piston rod retracted state, and the left lower extrusion die 213 and the right lower extrusion die 313 are at the lowest positions; the left and right squeeze clamp cylinders 209 are in a piston rod extended state, and the left upper squeeze die 212 and the right upper squeeze die 312 are in the highest positions. The upper finishing cylinder 401 is in a piston rod retracted state, and the upper finishing die 404 is in the highest position. The lower finishing die lifting cylinder 504 is in a piston rod extending state, and the lower finishing die 508 is at the lowest position; the lower finishing translation oil cylinder 501 is in a piston rod withdrawing state, and the lower finishing die 508 is far away from the working area; the finishing block translation cylinder 509 is in a piston rod retracted state. The back pressure clamping cylinder 604 is in a piston rod extending state, and the back pressure upper die 606 and the back pressure lower die 605 are in a separated state; the back pressure translation cylinder 602 is in a piston rod retracted state, and the back pressure upper die 606 and the back pressure lower die 605 are away from the working area. The oil holding cylinder 702 is in the piston rod retracted state, and the top plate 703 is in the lowest position.
First, the piston rods of the left and right extrusion cylinders 204 are slowly extended to a half-extended state, i.e., the left lower extrusion die 213 and the right lower extrusion die 313 are spaced apart by a center distance having a width equal to the straight section of the elbow to be finished. The piston rods of the left and right extrusion lifting cylinders 207 are extended, the left lower extrusion die 213 and the right lower extrusion die 313 are raised to the highest positions, the piston rods of the left and right extrusion cushion block cylinders 205 are extended, and the extrusion cushion block 206 is inserted below the extrusion lower die mounting seat 208. The piston rod of the back pressure translation cylinder 602 is extended until the inclined surface of the back pressure lower die 605 is stopped when it contacts the inclined surfaces of the left lower extrusion die 213 and the right lower extrusion die 313.
Next, the elbow portion of the elbow to be finished is placed into the cavity of the back pressure die 605. The straight section of the elbow to be finished is placed into the cavities of the lower left 213 and lower right 313 extrusion dies.
Then, the piston rods of the left and right press-clamping cylinders 209 are retracted, and the left upper press die 212 and the right upper press die 312 are lowered until they are fitted with the left lower press die 213 and the right lower press die 313. The back pressure clamping cylinder 604 piston rod is retracted, so that the back pressure upper die 606 is attached to the back pressure lower die 605. Then, the piston rods of the left and right squeeze cylinders 204 continue to extend to the final positions.
Further, the piston rods of the left and right squeeze clamp cylinders 209 are extended, and the left upper squeeze die 212 and the right upper squeeze die 312 are raised back to the highest positions.

The piston rod of the back pressure translation cylinder 602 is retracted, and the back pressure upper die 606 and the back pressure lower die 605 are withdrawn from the working area.
Then, the piston rod of the lower finishing translation cylinder 501 is extended, and the lower finishing die 508 enters the working area. The lower finishing die lifting cylinder 504 piston rod is retracted to raise the lower finishing die 508 to the highest position. The piston rod of the oil supporting cylinder 702 is retracted, the top plate 703 is returned to the lowest position, and the elbow falls into the cavity of the lower finishing die 508. The piston rod of the finishing cushion block translation cylinder 509 extends out, and the finishing cushion block 510 advances below the lower finishing lifting shaft 506. The upper finishing cylinder 401 piston rod extends, passes through the middle safety confirmation position, continues to extend until the upper finishing die 404 and the lower finishing die 508 are completely attached, and is maintained for a certain time.
Next, the upper finishing cylinder 401 piston rod is retracted, the upper finishing die 404 is raised to the highest position, the finishing block translation cylinder 509 piston rod is retracted, and the finishing block 510 is withdrawn from under the lower finishing lifting shaft 506. The lower finishing die lifting cylinder 504 piston rod extends, the lower finishing die 508 descends to the lowest position, the lower finishing translation cylinder 501 piston rod retracts, and the lower finishing die 508 withdraws from the working area. And finishing the processing step of the finished elbow.
The process completes the extrusion finishing of a small-radius elbow. To finish the extrusion finishing of another elbow, only the above process needs to be repeated.
The device changes the fixing mode of the traditional extrusion die, so that the left extrusion die and the right extrusion die can be lifted in the vertical direction; the finishing lower die can be lifted in the vertical direction and can also move in the front-back direction so as to give up a working space when the extrusion die works; in the working process, in order to avoid the stress of the extrusion die lifting oil cylinder and the finishing lifting oil cylinder, a cushion block mechanism is added, and the cushion block transmits pressure to the lathe bed, so that the whole processing quality and efficiency are ensured.
