3、Equipment purpose：
3.1Transmission adopts direct current motor through first-class retarder and flywheel to fulfill reciprocating. Also can adopt right and left installation methods according to customers?need.
3.2Operating frame reciprocates in engineer base which is made up of right, left board and soleplate. Frame is open structure, change and adjustment of pass are very easy, gears are meshed with rack.. When operating frame reciprocate, roller axis and ring pass revolve along frame stroke to roll pump materials. Scaleboard of frame adopts wearable material.
3.3Inlet and outlet chuck are separately fixed on central and back of rolling mill (add one in front part of lengthening truck) through import of gear turing feeding truck, synchronously move with operating frame.
3.4Feeding is through two lead screws to drive dolly into pump material to fulfill rolling. Feeding quantity is adjusted by lead screw.
3.5Mandril dolly is meshed to gears, so as to drive the running of mandril pole. Upper axis is through leader fixed in predetermined position. When pump materials are rolled, mandril back to dolly and waiting to be refilled.
3.6Feeding bracket consists of bracket and manipulator, when mandril dolly back to predetermined position, manipulator put pump material into leading track and then delivery by dolly to pass rolling..
4、hydraulic pressure and technical lubricating system：
4.1Hydraulic pressure use homemade high-performance vane pump, adopting electromagnetic valve and pressure valve produced by HUADE Group Company (former Beijing Hydraulic Pressure Products Factory)
4.2Technical lubricating system is made up of heat-resisting gear pump group, not only supply lubrication to operating slide, gear, gear rack but also to inner and outer surface of pump materials. Ring nozzle of special design, fixed in front and back part of operating base, lubricate and cool inner and outer surface of pump material and roller.
5、electrical control system：：
Adopt Z2 direct current timing electromotor, KM figure control cabinet of Hangzhou Motor Factory
