Technical Field

The invention belongs to the field of casting production, and particularly relates to an empty box buckling device and method in the field.

Background

In a foundry line, the flask is an essential piece of equipment, and the movement of the flask is often critical for the entire line. In V-method casting, the production line of the molding part comprises the process flows of film baking, film coating, empty box buckling, sand adding, compaction and the like, wherein the empty box buckling is to place an empty sand box on a mold and then add sand into the empty sand box for compaction so as to carry out subsequent processes.

The traveling crane or the empty box buckling manipulator is commonly used in the previous empty box buckling process, and the two empty box buckling modes both need to design specific structures on the sand box (design specific box grabbing handles on two sides of the sand box), so that the investment cost of customers is increased.

Disclosure of Invention

The invention aims to solve the technical problem of providing a buckling empty box device and a buckling empty box method without installing box grabbing handles on two sides of a sand box.

Furthermore, two sides of the hydraulic cylinder are respectively provided with a guide rod which extends to the hollow part of the working platform and can move up and down, and the bottom of the guide rod is fixedly arranged at the top of the base.

Furthermore, the tops of the two guide rods are fixedly connected through a reinforcing rod.

Furthermore, the bottom of the electromagnetic box grabbing manipulator is a strip-shaped electromagnet, and a buffer spring is arranged between the strip-shaped electromagnet and the bottom of the electromagnetic box grabbing manipulator.

Further, the number of the buffer springs is two.

The improvement of the method for buckling the empty box by using the device for buckling the empty box is that the method comprises the following steps:

(1) the hydraulic system drives the hydraulic cylinder of the lifting platform to enable the telescopic rod and the two guide rods to drive the base to extend downwards from the hollow part of the working platform to the box grabbing station;

(2) electrifying strip-shaped electromagnets at the bottoms of the two electromagnet box grabbing manipulators, and adjusting the magnetism of the electromagnets according to the size of the sand box so as to suck the sand box;

(3) the motor drives the travelling trolley to slide along the parallel track, the strip-shaped electromagnets at the bottoms of the two electromagnet box grabbing manipulators are powered off after the sand box is moved to the sand box placing station, and the sand box is placed to the sand box placing station;

(4) the motor-driven walking trolley slides back along the parallel tracks, and meanwhile, the hydraulic system drives the lifting platform hydraulic cylinder to enable the telescopic rod and the two guide rods to drive the base to retract upwards to a vacant station.

The invention has the beneficial effects that:

the empty box buckling device and the empty box buckling method can accurately grab the sand box and place the sand box on the mold, and can be used for grabbing sand boxes of any size. Need not design specific case handle of grabbing on the sand box, utilize the magnetism of electromagnet to hold the back from the top surface to the sand box, drive the sand box by the walking dolly and remove, simple light has improved production line degree of automation and production efficiency when reducing customer investment cost. The electromagnet box grabbing manipulator is simple in structure and can be popularized and applied in other fields.
