The technical solution adopted for the present invention to solve the technical problems is: a kind of oblique double hydraulic cylinder side core-pullingMechanism, comprises two unit of loosing core, 30 °～60 ° of the direction angulations of loosing core of described two unit of loosing core, described in take outCore unit comprises support, hydraulic cylinder, slide block and side core, and described hydraulic cylinder comprises cylinder barrel and piston rod, instituteState cylinder barrel and be fixed on described support, on described support, be fixed with linear guides, the guiding of described linear guidesParallel with the flexible direction of described piston rod, described slide block respectively with the end of described side core and described piston rodPortion is fixedly connected with and is slidably matched with described linear guides, is also provided with locating piece on described side core.
Concrete, the two ends of described slide block are fastened with respectively piston rod contiguous block by screw and are connected with side corePiece, the upper end of described piston rod contiguous block offers draw-in groove, and the end of described piston rod is fastened on described draw-in grooveIn and fastening by being arranged on threaded connector on described piston rod, conduct is extended in one end of described side coreConnecting rod is fixedly connected with described side core contiguous block.
As preferably, described linear guides comprises a linear protrusion and two-lines guide pad, described twoLinear steering piece is parallel with described linear protrusion and be arranged on the both sides of described linear protrusion, and described piston rod connectsThe bottom that connects piece, side core contiguous block and slide block all has a groove matching with described linear protrusion,Described piston rod contiguous block, side core contiguous block and slide block are perpendicular to described width one of loosing core in directionCause and and described two-lines guide pad between distance consistent.
Concrete, also comprising the cylinder barrel contiguous block being fixedly connected with described cylinder barrel, described cylinder barrel contiguous block is fixedBe arranged on described support.
In addition, also comprise wedge block, between described slide block and described linear guides, can limit by described wedge blockRelative sliding processed.
The invention has the beneficial effects as follows, this oblique double hydraulic cylinder side core-drawing mechanism adopts hybrid johning knotStructure, has improved connection precision and kinematic accuracy between piston rod and side core effectively, adopts two locating pieces,Reasonably determine the installation site of two side cores, improved installation accuracy and production efficiency.
