One kind is not had crack ring the machine of annulus of Zhan of vertical numerical control that rolling shapes () of the machine that grind annulus, reaming machine, jumped limited company of numerical control machinery to develop production success by Jinan spring recently, it is one kind suits to machine medium or small annulus machine of annulus of Zhan of radial of vertical numerical control. Its structure is compact, sexual price is wider than tall, size range of pipe bent, the annulus that suits rolling 300mm~1500mm very much, rolling process is successful and smooth, finished product annulus dimension precision is tall, manufacturing specific power consumption is low. Equipment applies to steel qualitative annulus already rolling production, also apply to the annulus of special type material such as aluminium alloy rolling production, rolling process automata, artificial intensity is inferior. The spring jumps numerical control company and declared the protection of national patent at the same time. In modern industry, without crack ring application is very wide, for instance flange of circle of the coat inside bearing, gear group, conduit, hub, circumgyrate is propped up, the strengthens engine of circle, aircraft housing of the group of runner coming back that has heavy transport to go up, pressure vessel and casing are waited a moment. Aluminium alloy material with intensity the characteristic with tall, light weight, in annulus go up application is wider and wider also. But aluminium alloy material forgings temperature range is narrow, some material are qualitative soft and stick, some is hard and fragile, rolling process is controlled not easily, technical demand is high, the hand uses machine of pilot Zhan annulus serious to this incommensurate, the requirement leaves bigger mental allowance to cause material to waste thereby. Home's at present mature annulus rolling equipment, have tilt machine of annulus of vertical radial Zhan, with horizontal diameter - machine of axial Zhan annulus. The annulus to rolling 300mm~1500mm, especially the annulus with the aluminium alloy qualitative material of this limits, these two kinds of equipment are put in certain limitation. Tilt principle of rolling of machine of annulus of vertical radial Zhan is shown 1 times like the graph, have an oriented roller only, signal roller is restricted to slant because of structural place park left underside and cannot feedback in real time annulus dimension, the external diameter circumstance when rolling relies on to undertake range estimation artificially, measure not accurate, the hand moves control operation, treatment precision is low, and agree with only the annulus under rolling diameter 1000mm. Graph 1 tilt the problem that the technical group that spring of Jinan of sketch map of principle of work of engine of vertical Zhan annulus jumps limited company of numerical control machinery produces applied place to arise in the light of this kind, vacate dragon v company to communicate with Shaanxi, decided the supplier concerns, created opportunity of annulus of Zhan of radial of numerical control of this kind of vertical. This facility construction is reasonable, size range of pipe bent is wide, PLC controls rolling process, finished product annulus dimension precision is tall, and need a very small installation ground hole only. Graph the front view of the 2 front view when expecting for fluctuation and rolling condition holds roller semmetry in the arms twice to decorate in annulus on half, advocate two side; and core roller cooperate roller those who realize whole rolling process decided a circle at 3 o'clock. Through PLC control holds synchronism of roller oil cylinder in the arms, assure movement of two semmetry that hold roller in the arms. Measuring oil cylinder action to fall, real time detects the place that measures roller, also measured annulus with respect to real time external diameter, realized PLC pilot automatic rolling. Sex of the fruit when measuring what the rod made sure in central on-line motion external diameter is measured, effectiveness, accuracy. Photograph comparing tilts individual and oriented roller and signal roller can increase chance of annulus of vertical radial Zhan greatly annulus ovality and measure accuracy. CNC Milling
