Product Description

 

Z28-80c thread rolling machine is a multifunctional cold extrusion rolling thread machine, the workpiece in the cold rolling pressure range can be made to straight lines, twill, spur, helical and bevel gear spline rolling; straightening, necking, rolling light and various rolling forming. The machine has safe and reliable electric liquid control system and implementation, which can make each work cycle in manual, semi-automatic and automatic selection in three ways.

 

The cold rolling is an advanced non cutting process, which can effectively improve the internal and surface quality of workpiece, the radial compressive stress produced during processing, and can significantly improve the fatigue strength and torsion strength of the workpiece. It is an ideal process with high efficiency, energy saving and low consumption.

 

Working principle:

L and R are two pairs of involute rolling wheels with the same parameters, which are installed on two spindles of the Z28-80c thread rolling machine, and can rotate synchronously under the drive of the transmission mechanism.The R wheel can be driven by the oil cylinder for radial feed motion, and the L wheel can be adjusted by adjusting the mechanism to coincide with the indentation of the R wheel on the surface of the workpiece P. The P locate the two center hole clamping, the adjustment fixture can make the axial movement in the force around the fixture O and spindle parallel to the axis of an angle, to ensure that the workpiece in the cold rolling process and keep two rolling wheels to roll in the free state, and convenient clamping the workpiece. The structure size, geometrical tolerance and technical requirements of the rolling wheel are formulated according to the rolling wheel and cylindrical measuring gear. The length of the normal line or the cross bar distance of the rolling wheel M is calculated according to the spline data of the gear, and the required material can be Cr12MoV (hardness 59 ~ 62HRC)

 

Application

 

Classification:

Z28-80c thread rolling machine is divided into two axis rolling machine and three axis thread rolling machine

1, two axis wire rolling machine has very strong superiority in hardware building, automobile and motorcycle fittings, traffic power, standard parts.

2, three axis rolling machine is triangle support in the pipe thread processing industry, true fidelity roundness, concentricity and perpendicularity

Product protection

 

Common problems and treatment methods of Z28-80c thread rolling machine:

 

1.Reverse

The front stroke switch is out of order (about 7000 times), and the time delay relay does not work;

There is not enough distance between the blocks and the pressure stroke switch, the block pressure is not in place or the damage is blocked;

Wiring off; contact contact is bad or damage;

Check whether the front limit contact is not in place, whether the closing point is broken, whether the opening point is closed and the time relay opening point is closed;

Check the machine behind the limit, closed point is broken, check the line point, line is loose, bad contact, damage, broken line, etc.;

 

2.Can not start

Reversing total stop in the closed phase power supply;

The heat protector has protective effect, and the insurance is burnt out;

The wiring fell off and the transformer burned out

Control line contact is damaged or bad contact

Check stop start button, whether or not drop loose, button contact is good;

Check whether the limit contacts in front of the equipment are good, whether the contact, line and insurance are damaged (the transformer enters, out of the insurance)
