Summary of skew rolling mill
Skew rolling mill to produce special rotary parts or blank two roll Angle of skew rolling mill is commonly 2 ~ 6, roll on the spiral groove, when the two roller, spinning the synthetic of round billet between roller and a reverse rotation and roll forward, through the spiral groove rolling of round into the required shape.
Steel ball skew rolling principle
Screw groove diagonal rolling as shown in figure 2, the working principle of two roll with the spiral groove, and the interaction of the axis roll in the same direction of rotation shaft drive round workpiece rotate and move forward, under the action of rolled piece in the spiral groove, forming blank skew rolling deformation is mainly of axially symmetrical parts diameter compression axial extension.
The process of steel ball rolling
Hot rolled steel ball, with induction heating device the first diameter smaller than the diameter of the rolling a ball around 4% of the round steel billet heating to 850 ~ 1100, ball bearing steel take good floor heating bar rolling into the skew rolling mill
Roll line and the rolling line tilt Angle spiral groove on the roller rolled piece screw Under the effect of the spiral groove, the round steel gradually become spherical, spherical connection between the neck part is more and more thin, after the last disconnect for ball mill ball after further processing of the final product of steel ball roll pass consists of two parts, forming and finishing Forming period pass completion bite into the blank, and the round bar rolling into a ball.Finishing section of rolled piece by finishing and separation with blank pass in 1170 ~ 1350, the total length of bearing steel ball generally take between finishing part is around a circle Forming period for one and a half to two times Forming period is too long can make the bar stock rotation in the pass number increase, easy to cause central loose ball and pore space
The groove of steel ball of the ball grinding principle and bearing steel balls are basically the same But the helical groove of steel ball of the ball mill finishing ribbed rise to or slightly higher than the workpiece axis, to cut the rolled piece tail net finishing period of groove rib is flat, do not need to open store manger groove of steel ball of the ball mill finishing period is more than bearing steel ball groove lengthen The pass generally take the total length of 1260 ~ 1350.
Main technical parameters of skew rolling steel ball machine
After my company engineering and technical personnel of steel rolling production line fully research, combining with the steel market demand at home and abroad, development and manufacture of a new generation of ball rolling production line, developed the D20 - D120 series from heating rolling and heat treatment, etc. Series of complete sets of steel ball production line, used in the production of various specifications of steel ball diameter from 20-120.
