Technical Field

The invention relates to the technical field of flow coating equipment in a resin sand molding production line in the casting industry, in particular to an online flow coating machine for casting.

Background

The flow coating process is adopted in the casting industry after the sand mold is stripped in order to obtain good casting surface quality. A tilting flow coating machine is adopted in the former production line, after a sand mold is clamped on a roller way, the sand mold is tilted around a rotating shaft on the outer side of the roller way to form the flow coating after the production line. The machine type adopts a labor-consuming lever structure which rotates around the end part, the whole structure is not well stressed, the machine type is huge, a hydraulic power system is high in energy consumption, and a worker has certain potential safety hazards below a sand mold during flow coating. The other type is a moving-out type flow coating machine, after a sand mold is clamped by a mechanical arm, the sand mold rises to leave a roller way, is driven by a traveling mechanism to move horizontally to a production line, and is driven by a turnover mechanism to turn over for a certain angle to perform flow coating. The machine type solves the potential safety hazard problem, but has more complex integral structure, more operation actions and long beat time, and becomes equipment for limiting the whole line efficiency of a production line. To date there is no suitable apparatus on the market that fully addresses the above problems, requiring the development of an entirely new apparatus to meet these needs of the cast product line flow coating process.

Preferably, base rotation mechanism includes two bases, fixes two support column on the base, fixes two supporting wheel and drive on the support column supporting wheel pivoted hydraulic motor, hydraulic motor with one of them the supporting wheel is connected, supporting wheel and two rotation axis connection between the base, the other end and another of axis of rotation the supporting wheel is connected, two the supporting wheel with the outer wall of revolving drum contacts.

Preferably, the roller way mechanism comprises roller way frames fixed inside the rack, roller ways fixed between the roller way frames and a motor driving the roller ways to move, and the motor is fixed at the end parts of the roller way frames.

Preferably, the clamping mechanism comprises two clamping frames fixed below the roller way mechanism and manipulators fixed on the two clamping frames, the manipulators are in contact with the sand mold, the two clamping frames are connected through a telescopic rod, and the bottom ends of the two clamping frames are connected with an oil cylinder.

Therefore, the casting on-line flow coating machine adopting the structure has the following beneficial effects:

(1) the online flow coating of the sand mold is realized, the sand mold can be turned over after being clamped on a roller way, the roller way line does not need to be turned out, the sand mold does not need to be moved out of a production line through a manipulator, and the online flow coating in the real sense is realized;

(2) the beat time is short, and the gravity center of the rotary part is basically the rotary geometric center after the sand mold is clamped, so that the state of the equipment is conveniently controlled, and the running speed is improved;

(3) the stability is high, the sand mold is clamped and turned after being in place, other actions are avoided, the speed of the equipment is increased, the mechanism is simplified, and the stability of the equipment is improved;

(4) the sand mold is always arranged in the frame in the whole action process, a certain safety distance is kept between the sand mold and workers, and the equipment is safe and reliable;

(5) the automatic operation can be realized in the processes of sand mold entering and exiting the roller way, clamping and overturning without manual intervention, the labor intensity of workers is reduced, and the production efficiency is improved;

(6) the sand molds with different sizes are compatible, the sand molds within the maximum opening size of the clamping mechanism can be normally used, and the flow coating requirements of the sand molds with different sizes and specifications on a production line are met;

(7) the sand mould is energy-saving, only has two actions of clamping and overturning after the sand mould is in place, the gravity center of the rotating part is basically the geometric center of rotation in the overturning process, and thus, only small force is needed for driving, and the power consumption of the whole machine is greatly reduced.
