The specific work process and principle of this patent are as follows:
The original state of this extruding finishing machine is that left and right two extrusion oil cylinders 204 are in piston rod retracted state, left extruding
Mechanism 2 and right pressing mechanism 3 are far from working region;Left and right extruding cushion block oil cylinder 205 is in piston rod retracted state;It is left and right to squeeze
Pressure lifting cylinder 207 is in piston rod retracted state, and lower-left extrusion die 213 and bottom right extrusion die 313 are in extreme lower position;Left,
Right extruding clamping cylinder 209 is in piston rod and stretches out state, and upper left extrusion die 212 and upper right extrusion die 312 are in extreme higher position.
Upper finishing oil cylinder 401 is in piston rod retracted state, and upper die finish 404 is in extreme higher position.At lower die finish lifting cylinder 504
State is stretched out in piston rod, lower die finish 508 is in extreme lower position;Lower finishing translation oil cylinder 501 is in piston rod retracted state,
Lower die finish 508 is far from working region;Finishing cushion block translation oil cylinder 509 is in piston rod retracted state.Back pressure clamping cylinder 604
State is stretched out in piston rod, back pressure upper mold 606 and back pressure lower die 605 are in discrete state;Back pressure translation oil cylinder 602, which is in, lives
Stopper rod retracted state, back pressure upper mold 606 and back pressure lower die 605 are far from working region.Support oil extraction cylinder 702 is in piston rod and withdraws shape
State, top plate 703 are in extreme lower position.
Firstly, 204 piston rod of left and right two extrusion oil cylinders slowly extend out to half stretching state, i.e. 213 He of lower-left extrusion die
Bottom right extrusion die 313 is at a distance of the centre distance that width is to finishing elbow straight part.The left and right work for squeezing lifting cylinder 207
Stopper rod stretches out, and lower-left extrusion die 213 and bottom right extrusion die 313 are raised up to extreme higher position, left and right 205 piston of extruding cushion block oil cylinder
Bar stretches out, and squeezes the insertion of cushion block 206 and squeezes 208 lower section of lower die mounting base.602 piston rod of back pressure translation oil cylinder stretches out, until back
Stop when depressing the inclined-plane of mould 605 with the contact of incline plane of lower-left extrusion die 213 and bottom right extrusion die 313.
Secondly, the elbow part to finishing elbow is put into the type chamber of back pressure lower die 605.By the straight section to finishing elbow
It is partially placed into the type chamber of lower-left extrusion die 213 and bottom right extrusion die 313.
Then, the left and right piston rod for squeezing clamping cylinder 209 is withdrawn, under upper left extrusion die 212 and upper right extrusion die 312
Drop, is bonded until with lower-left extrusion die 213 and bottom right extrusion die 313.604 piston rod of back pressure clamping cylinder is withdrawn, and is made in back pressure
Mould 606 and back pressure lower die 605 are bonded.Then, 204 piston rod of left and right two extrusion oil cylinders continues to extend out to final position.
Further, the left and right piston rod for squeezing clamping cylinder 209 stretches out, upper left extrusion die 212 and upper right extrusion die 312
Rise back to extreme higher position.604 piston rod of back pressure clamping cylinder stretches out, and separates back pressure upper mold 606 and back pressure lower die 605.Left,
Right 205 piston rod of extruding cushion block oil cylinder is withdrawn, and is squeezed cushion block 206 and is exited below extruding lower die mounting base 208.It completes to squeeze at this time
The step of bending head.
204 piston rod of left and right two extrusion oil cylinders is retracted to suitable position, keeps left pressing mechanism 2 and right pressing mechanism 3 remote
From working region, next step finishing procedure is carried out.
Into next process, left and right 207 piston rod of extruding lifting cylinder is withdrawn, and lower-left extrusion die 213 and bottom right squeeze
Mould 313 drops to extreme lower position.702 piston rod of oil extraction cylinder is ask to stretch out, top plate 703 is increased to extreme higher position, and elbow is under back pressure
It is detached from mould 605.602 piston rod of back pressure translation oil cylinder is withdrawn, and back pressure upper mold 606 and back pressure lower die 605 exit working region.
Then, lower 501 piston rod of finishing translation oil cylinder stretches out, and lower die finish 508 enters working region.Lower die finish lifting
504 piston rod of oil cylinder is withdrawn, and lower die finish 508 is made to rise to extreme higher position.702 piston rod of oil extraction cylinder is ask to withdraw, top plate 703 returns
To extreme lower position, elbow is fallen into the type chamber of lower die finish 508.509 piston rod of finishing cushion block translation oil cylinder stretches out, finishing cushion block
510 advance to lower 506 lower section of finishing lifting shaft.Upper 401 piston rod of finishing oil cylinder stretches out, and confirms position by middle security, after
It is continuous to stretch out until upper die finish 404 and the fitting completely of lower die finish 508, and keep certain time.
In next step, upper 401 piston rod of finishing oil cylinder is withdrawn, and upper die finish 404 rises back to extreme higher position, and finishing cushion block is flat
It moves 509 piston rod of oil cylinder to withdraw, finishing cushion block 510 exits below lower finishing lifting shaft 506 and returns to original position.Lower die finish lifting
504 piston rod of oil cylinder stretches out, and lower die finish 508 drops to extreme lower position, and lower 501 piston rod of finishing translation oil cylinder is withdrawn, lower essence
Mould preparation 508 is withdrawn from from working region.The procedure of processing of finishing elbow is completed at this time.
The above process is the extruding finishing for completing a short-radius bend.Complete the extruding essence of another elbow
It is whole, it is only necessary to repeat the above process.
The equipment changes the fixed form of previous extrusion die, go up and down left and right extrusion die can in vertical direction;Under finishing
Mould can be gone up and down in vertical direction, can also be mobile in front-rear direction, to concede working space when extrusion die works;Worked
Cheng Zhong increases cushion block mechanism in order to avoid extrusion die lifting cylinder and finishing lifting cylinder stress, extremely by cushion block transmitting pressure
Lathe bed guarantees whole processing quality and efficiency.
