Hangji brand pre-ending mill

The purpose of pre-ending mill
In the method of higher-speed wire-rod rolling&comma pre-finishing mill can enhance the precision of the operating piece to guarantee the item high quality and avoid attainable procedure failure for the duration of the finishing mill area&periodThe composition of framework
Its construction is two horizontal and two vertical &lparhorizontal-vertical-horizontal-vertical&semi H-V-H-V&rpar cantilever variety&comma it is really compact&comma and the fat adjustment is a lot more exact and dependable&comma and so to keep away from possible twi EPT rolling&time period
Pre-finishing mill is composed by two horizontal mills&comma three vertical loops&comma two vertical mills&comma basic safety cover and so on&periodEquipment construction
Transmission box
The part of transmission box is to transmit the instant outputted by reduction gear and motor to roll shafts&period Horizontal box has a pair of cylindrical bevel gears&semi vertical box has a pair of extra spiral bevel gear beside a pair of cylindrical bevel gear&period The spiral bevel equipment speed ratio of the two vertical transmission boxes is distinct&interval
Roller box
Every single roller box has one particular upper roll shaft and a single reduce roll shaft&semi they are not meshed&comma and pushed by a pair of cylindrical bevel gears in the transmission box&time period
A cantilever cylindrical roll shaft is mounted to each and every roll shaft&semi the roll shaft is set in the eccentric locking collar and sustained by the front and rear film bearing&time period Pushed by the remaining and appropriate feed screw and nut of the shaft gap adjustment unit&comma the eccentric locking collar can make the higher and decrease roll shaft open and shut symmetrically and evenly relate to the milling centre line&comma in so to achieve roll shaft gap adjustment&period The roll shafts are created of tungsten carbide&period of time
The roller box is put in with flange in plug-in strategy&comma
and practical to assembly and disassembly&comma the roller box and transmission box are personal unites&comma throughout the installation&comma assemble the roller box and transmission box at the fir EPT stage and then resolve the roller box inside of the transmission box with screw bolt&comma the roller box is positioned by two finding pins to acquire accurate situation&time period In this way&comma the set up can be completed easily and with a shorter time&comma in the meantime&comma the pipework on the panel is lowered and make it less difficult for failure dealing with&period of time 1&comma The roller hole is altered by utilizing the eccentric locking collar&comma by changing the lead screw and nut &comma the eccentric locking collar will spin and then drive the roller shaft to shift symmetrically&comma in so to achieve the adjustment of roller shaft hole&time period The be EPT benefit of this adjustment approach is that the central line will be kept unchanged&period
2&comma By using the thru EPT bearing that mounted at the conclude of the roller shaft&comma we can effectively stop the axial change of the roller shaft&comma in so to guarantee dimension precision of the item&period
three&comma the dimension and framework of the roller box for horizontal framework and vertical framework are the same&comma all the areas are interchangeable&interval
four&comma the electrical power transmission and velocity control are executed by a pair of spiral bevel gears in the transmission box&comma the reducer is omitted from the transmission method of the vertical rolling mill&comma so that the entire equipment is lighter and more compact&period of time
5&period of time As the horizontal framework is completely symmetrical&comma it can be rotated a hundred and eighty&comma so it can be shared by two creation strains that found at its appropriate and still left facet&interval
Xihu (We EPT Lake) Dis. gadget
The entrance of roller box has put in scroll manual and slip information&comma the exit of roller box ju EPT has slip manual&comma slip information is lubricated by particular lubrication system&interval
