Abstract
A portable mold adjusting device allows for relatively precisely adjusting the mold cavity size of a slab caster mold during casting. The portable mold adjusting device includes a dolly to facilitate transport of the device to molds requiring an adjustment. A mechanical drive is secured to the dolly. A free end of the drive is provided with a coupling adapted to be coupled to the adjustment mechanism on an adjustable slab casting mold. The other end of the mechanical drive is directly coupled to a reversible electric motor. The mechanical drive is encoded to allow for relatively precise positioning of the adjustable mold walls.
Claims17
A portable mold adjusting device for adjusting the mold cavity size of a slab caster mold during casting comprising:
- means for supplying a source of mechanical power;
- means coupled to said supplying means for transmitting said source of mechanical power to rotate a driveshaft;
- a driveshaft rotatably mounted, coupled to said transmitting means;
- means coupled to said driveshaft for fitting on and rotating a fastener whose rotation adjusts the cavity size of a mold;
- means for carrying said supplying means, said transmitting means, said driveshaft and said rotating means which includes means for transporting said carrying means;
- and
- means for measuring the rotation of said driveshaft and monitoring change in mold cavity size resulting from the rotation.
A portable mold adjusting device comprising:
- means including an electric motor having an output shaft and means for measuring the rotation of said output shaft and monitoring change in mold cavity size resulting from the rotation for adjusting the mold size of a caster;
- means for carrying said adjusting means;
- means for allowing rolling transport of said carrying means;
- and
- means, coupled to said output shaft, for transferring the power in said output shaft about an axis generally perpendicular to said output shaft.
A portable mold adjusting device for adjusting the mold cavity size of a slab casting mold comprising:
- an electric motor having an output shaft;
- a driveshaft;
- first coupling means for coupling said driveshaft to said output shaft;
- means for adjusting said mold cavity size;
- second coupling means for coupling said adjusting means to said driveshaft;
- means for carrying said electric motor, said driveshaft, said adjusting means and said first and second coupling means;
- means for providing rolling support for said carrying means;
- control means for said electric motor comprising means for speed control and means for operating the motor in a desired direction of rotation in order to increase or decrease mold size cavity size;
- and
- means for indicating the mold size cavity change whereby operation of the control means and observance of the means for
- a driveshaft rotatably mounted, coupled to said transmitting means;
- means coupled to said driveshaft for fitting on and rotating a fastener whose rotation adjusts the cavity size of a mold;
- means for carrying said supplying means, said transmitting means, said driveshaft and said rotating means which includes means for transporting said carrying means;
- and
- means for measuring the rotation of said driveshaft and monitoring change in mold cavity size resulting from the rotation.
