Professional steel ball machine tool manufacturing enterprise
Provide a variety of steel ball manufacturing solution
Skew rolling mill production line used to produce steel balls or steel forging. The angle between the two rolls of the skew rolling mill is generally 2 ° -6 °. The roll has a spiral hole pattern. When the two rolls are rotated in the same direction, the round billet rotates reversely with the roll between the rolls and advances through the spiral hole Round bar rolled into the desired shape. Then after the heat treatment process to meet the requirements of grinding steel ball.
The work principle of helical hole type cross rolling is shown in the figure. Two axes with helical hole cross each other. The rollers rotate in the same direction to rotate and advance the circular piece, under the action of forming rotary parts blanks. Skew rolling deformation is mainly axial compression of the axial extension.
|Steel ball diameter||mm||15-20||20-30||30-40||35-50||40-60||60-80||70-100||80-120|
|Roller angle range||°||0-5||0-6||0-6||0-8||0-6||0-8||0-7||0-7|
The part has the storage 6000MM long bar steel rack, automatic feeding, automatic feeding, automatic temperature measurement, fault alarm and other functions, the high degree of automation of the furnace, to ensure continuous production of steel ball production line.
Host using the overall ZG35 cast steel frame structure, aging treatment, good rigidity. Roller spindle 40Gr forgings, the whole quenched and tempered HB220 ~ 280; bearing ZG35, after aging. The spindle and bearing seat are connected by tapered roller bearings. The bearings are made of domestic first-class bearings (Hawal brand), lubricated with high-temperature lubricating oil and sealed by mechanical seal. The overall performance is stable and reliable.
Radial and axial adjustment of the mold is convenient and reliable, the locking is firm and stable, and the ball quality and operation stability are ensured.
According to different bar diameter, with different specifications of the guide sleeve.
Box with Q235-B welding parts, to stress annealing, gear with hardened helical gear and long service life; output shaft material 40Cr, quenched and tempered HB217-255. Motor, reducer, dual output reducer installed in a whole foundation, the power transmission part of the smooth operation.
Motor and reducer, reducer and dual output reducer connection between the flexible pin-type coupling, low noise, smooth transmission.
Electrical control part of the motor start, stop, speed button, with a voltmeter and ammeter, timely monitoring of voltage and current, electrical components using well-known brands. In addition, there are some features such as open the door power-off and motor over-current protection.
Mold material for H13 high quality mold steel, the overall quenching, under normal use can produce 20-30 million steel balls.
The upper and lower guide plate with high quality welding layer to increase the surfacing layer to improve the wear resistance of the guide, after a simple repair wear, grinding can continue to use. Up and down guide adjustment by manual adjustment.
