Electrostatic eliminating, chip removing and dust sucking device for lost foam casting forming machine

Abstract

The invention relates to a chip removing, dust sucking and electrostatic eliminating method and a chip removing, dust sucking and electrostatic eliminating device for a lost foam casting forming machine. A blowing and sucking integrated chip removing and dust sucking device comprises a dust sucking cover, a single ion spray nozzle and an air pipe; the dust sucking cover is connected with a main shaft of a machine tool; the single ion spray nozzle is arranged on a positioning seat of the main shaft of the machine tool in an angle adjustable manner through a ball joint; the air pipe is connected with the ion spray nozzle. A method for neutralizing chip ions by high-voltage ions comprises the following steps: generating air flow through an air compressor; connecting the electrostatic dust removal spray nozzle at an air outlet, wherein a large number of ion bodies generated by a high-voltage electric field flow with the air flow to be in contact with foam chips to neutralize the charges of the foam chips, and moreover, a large number of form chips can be blown near the negative-pressure dust sucking cover by high-speed air flow; chips fly near an air tool can be sucked away by the dust sucking cover and can be filtered and collected by a dust collection device through a pipeline. A small number of remaining chips fall down around a cutting surface along with the gravity, and are machined and collected in a unified manner. According to the blowing and sucking integrated device, the problems about blowing, removing and collecting the chips in the prior art are solved; a chip removal effect is good; the production cost can be reduced; the machining quality can be improved; the service life of the tool can be prolonged.

Description

technical field [0001] The invention relates to a method and device for removing static electricity, chip removal and dust collection for foam processing in lost foam casting technology. Specifically, it relates to a method for neutralizing foam static electricity in debris with high-voltage ions and vacuuming dust with a low-pressure air flow vacuum cleaner, which belongs to special processing field. Background technique [0002] Lost foam casting is to bond and combine paraffin or foam models similar in size and shape to castings to form model clusters. After brushing refractory paint and drying, they are buried in dry quartz sand for vibration modeling, and poured under negative pressure to vaporize the model. , a new casting method in which liquid metal occupies the position of the model, solidifies and cools to form a casting. It is a new technology with nearly no margin and precise molding. This technology does not need to take molds, has no parting surface and no san...

Problems solved by technology

[0007] In order to achieve the purpose of dust removal, according to the collection and cleaning of foam waste according to the present invention, in view of the fact that the existing negative pressure chip suction and high pressure chip removal cannot prevent the waste chips from splashing and sticking around, a method of blowing high-pressure chips, low-pressure chip suction and electrostatic ionization is proposed. This method introduces electrostatic dust removal rods and air compressors, and the ionization device forms a stable high-voltage electric field under the action of high voltage and low current generated by the high-voltage generator, and ionizes the air to form ions, which are brought by the high-pressure airflow It reaches the surface of the chip to neutralize the static electricity on the surface of the chip, prevent the chip from sticking everywhere inside the machine tool and remove dust.
