The structure of support 23 makes frame 1 all can adjust distance with on vertical direction in the horizontal direction, such that it is able to join suitable various sizes of pile tube, the steel reinforcement cage in pile tube is carried out stretch-draw, improves and join adaptive.
The operation principle of the present invention is:
The action of sliding seat driver 29 and frame driver 31, is adjusted frame 1, thus joining the pipe die of suitable corresponding size, it will be appreciated by those skilled in the art that when stretch-draw, and the axial line of the axial line of stretch-draw screw mandrel 3 and stretch-draw oil cylinder 2 should be on the same line.
When stretch-draw screw mandrel 3 be connected after axle 8 aligns, as mentioned above, stretch-draw oil cylinder 2 action makes connecting shaft oil cylinder 3 move forward, connect axle 8 and hold out against stretch-draw screw mandrel 103 end, stretch-draw oil cylinder 2 is shut down and keeps oil pressure, connecting shaft oil cylinder 3 works, promote coning sleeve 4 forward, grab block 5 slide along coning sleeve 4 and form contraction, the collar 9 grabbing block 5 snaps onto groove 10 and the end sides of stretch-draw primary nut 105, now stretch-draw screw mandrel 103 achieves a fixed connection with being connected axle 8, connecting shaft oil cylinder 3 quit work and keep oil pressure so that grab block 5 all the time be connected axle 8 and stretch-draw screw mandrel 103 forms a fixed connection.
Stretch-draw oil cylinder 2 task again, is now pull connecting shaft oil cylinder 3 to move, thus stretch-draw screw mandrel 103 is formed stretch-draw effect backward.nullAfter stretch-draw completes，Stretch-draw oil cylinder 2 keeps oil pressure，Compression cylinder 18 works，Drivewheel 14 and driven pulley 15 is made to be adjacent to stretch-draw big nut 104，Capstan drives 16 works and drives drivewheel 14 to rotate，Drivewheel 14 drives stretch-draw big nut 104 rotation to make stretch-draw big nut 104 screw toward near stretch-draw end plate 102 direction and be close to stretch-draw end plate 102，Owing to stretch-draw big nut 104 can move axially along stretch-draw screw mandrel 103 in turn process，Therefore drivewheel 14 also want can with stretch-draw big nut 104 synchronizing moving，Otherwise can cause that drivewheel 14 and stretch-draw big nut 104 misplace and stretch-draw big nut 104 cannot be driven to rotate further，Now can open with dynamic air cylinder 17，Spy plate 19 and drivewheel 14 is driven to move forward with dynamic air cylinder 17，It is in that on stretch-draw big nut 104 owing to the compacted cylinder 18 of drivewheel 14 compresses，Therefore drivewheel 14 achieves Tong Bu moving axially along stretch-draw screw mandrel 103 with in stretch-draw big nut 104，When stretch-draw big nut 104 holds out against stretch-draw end plate 102，The position of stretch-draw screw mandrel 103 is fixed，Stretch-draw oil cylinder 2 pressure release，Connecting shaft oil cylinder 3 pulls coning sleeve 4 toward bouncing back，Grab block 5 to depart from stretch-draw screw mandrel 103，Complete stretch-draw.
