Abstract
The invention relates to the field of metal casting. A sand core and a sand mold are respectively taken as a flow channel and a model for casting a metal product, the appearance quality and strength of the sand core and the sand mold are important indexes which urgently need to be improved; and currently, resin sand is normally used for manufacturing the sand core and a sand shell in the field of the metal casting, and as the appearance roughness and mechanical strength of the products cannot meet user indexes, the conventional processing method comprises the following steps of: manually smearing and brushing a coating on the sand core by a worker and carrying out natural drying, however, the operation method is primitive and burdensome, comprises lots of working procedures, is low in efficiency and high in the production cost and possibly affects the stability of the production quality. The invention relates to an automatic production line. According to the automatic production line, the coating is mechanically sprayed on the outer surface of the sand core to permeate in, intensify and refine the appearance of the sand core so as to improve the quality of the sand core, and the drying is carried out by utilizing the heat energy of a stovepipe of an aluminum melting furnace.
Description
Technical field
The present invention relates to field of metal casting technology, core, sand mo(u)ld are as runner and the model of cast metal goods, its apparent mass, intensity are this product important indicators anxious to be improved, the present invention adopts machinery at its outside spraying (or dip-coating) a kind of coating, allow its topped its surface improve apparent mass, and utilize molten aluminium furnace exhaust gas heat energy dry ruggedization, obtain a kind of automatized energy-saving production line that apparent mass satisfies customer requirements.
Background technology
At present in field of metal casting technology, resin sand commonly used is made core and arenaceous shell, but because apparent roughness, the mechanical strength of its product do not reach user's index, the method for processing at present is that the workman uses coating to adopt staff to smear, brush to core, artificial dip-coating is natural drying, or sintering.This operational method is original tired weight not only, and flow chart is many, render a service low, production cost is high, and is dangerous, also can affect the stability of yield and quality.
Summary of the invention
A kind of processing method of raising core apparent mass of the present invention and production line are a kind of core automatic coating (or dip-coating) drying lines that oneself manufactures and designs that adopted, surperficial at core the spray painting (or dip-coating) that can reduce core surface roughness increase sand core strength with automatic spraying machine (or dip coater), and utilize the production line that melts aluminium furnace exhaust gas heat energy dry ruggedization.Core automatic coating drying line only needs two people to handle, one people's clamping is sent into automatic coating case (or dip-coating) by pipeline and is rotated up and down evenly spraying (or dip-coating), enter the drying box rotation behind the outlet, people's pickup vanning, continuously operation after heated-air drying, balance.Core automatic coating drying line is carried core erecting by overhang (2) by carrier chain pylon (1), automatic coating case (3), and drying box (4) combination is made.Carrier chain pylon (1) is comprised of I-steel pillar (5), annular I-steel (6); Carry core erecting by overhang (2) to be formed by conveyer chain hanging wheel (7), conveyer chain (8), the suspension rod (9) that swing pinion is housed, gripper (10); Automatic spraying machine (3) by the rotation of spraying box casing (11), core chain (12), coating nozzle (13), be coated with bin (14), flux bath (15), electric rotating machine and speed adjusting handle (17) and form; Drying box (4) is comprised of with the molten aluminium stove chimney arm (25) of hot blast drying box casing (19), core rotation chain (18), drying air fan (20), electric rotating machine speed adjusting handle (21), blowing minute mouthful (22), air draft hood (23), exhaust blower (24), drying.
