Mandrel of Pay-off Reel and Pressure Reel

For hot rolling 
The mandrel is the key portion of sizzling rolling tension reel for coils&interval Coiling temperature is in between 550 to 850ºC&interval The mandrel has mainly two kinds&colon link wedge kind and double wedge variety&period

Url wedge type can also be divided into two types&colon link wedge-coupling drive and url-spline push&interval

For website link wedge-coupling variety rigidity reel&comma the mandrel is mainly composed of mandrel physique&comma spreader bar&comma phase&comma website link&comma wedge and spreading cylinder&interval Spreader bar has multistage slopes and phase is supported by multistage wedge&period of time Phase is linked with spreader bar by hyperlink so segment does not fall off&time period With compression spring in the middle of wedge&comma wedge can firmly speak to section and pyramid area&interval There is a gap in between the higher area of wedge and phase&comma which can reduce the impact of coil head to mandrel for the duration of coiling coil&period of time Mandrel entire body is mounted on two bearings&period of time Electricity is transmitted by crowned-teeth coupling in the true&time period It is quite handy to dismantle&comma and due to there is no equipment affect in the course of functioning&comma mandrel rigidity is improved&time period It’s very advantageous to control the dynamic tension&period of time

The spreading basic principle of mandrel&colon spreader bar moves within mandrel body in axial route dreivern by hydraulic cylinder&comma the slant of sperader bar pushes the wedge within radial hole of mandrel physique to go outward&interval The wedge surface pushes segment to increase outward&period of time Wedge diameter will expand&time period Right after coiling coils&comma spreader bar moves in the reverse course pushed by hydraulic cylinder&comma and pul EPT phase to shrink via link&period of time Wedge moves inward and mandrel diameter turns into smaller to discharge point out&time period Then you can get started to discharge coil&time period

For the two sorts of hyperlink wedge-coupling drive and website link wedge-spline push&comma the mandrel constructions and rules are almo EPT same and the primary difference is drive type of mandrel&period For url wedge-spline push sort&comma connection between mandrel and main transmission instances is spline&comma i&periode&period of time insert kind&time period When mouting and dismantling&comma mandrel can be immediately inserted or pulled out of the main transmission instances to obtain the rapid replacement&period
The principal driving motor drives gear shaft rotation by means of the intermediate shaft&period of time The equipment shaft dirves big equipment rotation&comma and the huge equipment drives mandrel rotation by means of spline&time period

For the double wedge type pressure reel&comma the mandrel is mainly composed of mandrel physique&comma spreader bar&comma section&comma spreader wedge&comma buffer wege and hyd&time period Cylinder&period

The spreading basic principle of double wedge type mandrel&colon hyd&period of time Cylinder makes spreader bar go back again and forth in axial path and the wedge move in radical course&period of time So the segment gets huge&period T-hook on spreader bar pul EPT wedge again and the hook exterior the wedge pul EPT section back again&time period This will make the manderel tiny&interval With spline connectiion for electrical power transmission unit&comma mandrel can be swiftly replaced&time period Cooling drinking water channel inside of the mandrel&comma so cooling impact is excellent&period of time Lubricant can be injected by car and guide type&comma so it can lessen areas put on&period of time

Spend-off reel and stress reel for cold rolling coi EPT are utilised in chilly rolling creation line or shell out-off when acid pickling&commagalvanization&commaannealing&commashear&commacoating or coil rigidity in out enable&interval
Chilly rolling mandrel is the crucial portion of spend-off reel and rigidity reel&interval According to different composition&comma it has beam wedge variety&comma pyramid axis type&comma pyramid sleeve type&comma wedge type&comma radial direction hydraulic cylinder variety&comma and many others&interval Or merely&comma open type and shut kind&period The close type mandrel is a close circle without having gap in the surface right after increasing&periodit is suited for coiling slim strip steel&period The open type mandrel indicates there is a hole among segments after mandrel growing&comma suitable for coiling thicker strip metal&period of time
For chilly rolling
Shell out-off reel and pressure reel for chilly rolling coi EPT are utilised in chilly rolling generation line or pay-off when acid pickling&comma gavanization&comma annealing&comma shear&comma coating or coil tension in outlet&period

Cold rolling mandrel is the important parts of pay out-off reel&pressure reel&period of time According to different construction&comma it has beam wedge type&comma pyramid axis variety&comma pyramid sleeve sort&comma wedge kind&comma radial course hydraulic cylinder sort&comma ect&period Or basically&comma open up kind and near sort&time period The near kind mandrel is a near circle without having gap in the surface right after increasing&period It is suitable for coiling slender strip metal&interval The open up type mandrel implies there are a gap among segment after mandrel expanding&comma ideal for coiling thicker strip steel&time period

The beam wedge variety mandrel is mainly composed of the major shaft&comma expanding core&comma section&comma axial direction wedge&comma radial direction wedge and spreading cylinder&comma etc&period of time There are two varieties of framework&colon with jaw or with out jaw&period The mandrel with jaw is utilised for coiling thicker strip steel&time period It can also be set with steel sleeve or paper sleeve to coil with belt wrapper&time period The mandrel without having jaw is used for coiling skinny strip steel by belt wrapper&period

The mandrel will move alongside axial course pushed by the expanding core & wedge block&comma through relative sliding between the wedge block and section&comma swelling and shrinking will take place in radial path&comma reset by spring&interval

The pyramidal axis type mandrel is divided into tapper type and again taper variety according to the tilting direction of axis slope&time period This mandrel has simple structure &commaless parts&comma massive main shaft area and large toughness &periodSo it can bear large tension&comma not only coiling &commabut also uncoiling&period There are two types of structure&colon with jaw or without having jaw &periodit’s primarily consisted of the pyramid axis&comma section&comma hollow sleeve and spreading cylinder&comma and so on&time period

Presently&comma the back taper type mandrel is the mo EPT common&interval The oil goes into the cylinder by means of a rod cavity&period of time The cylinder pul EPT the pyramidal shaft backward along axial route and drive section to grow outside the house&comma so the drum is expanded&time period Pyramidal axis moves again ward alongside axial course&comma and phase is pulled back again by the T-key&comma as a result the mandrel is shrinked&interval
