Abstract
The invention discloses an electric-heating airflow cutting head which comprises a high-temperature-resistant cup cover and a high-temperature-resistant resistor heating body. The electric-heating airflow cutting head is characterized in that the high-temperature-resistant resistor heating body is fixed in the high-temperature-resistant cup cover through a high-pressure ceramic cover plate and does not contact with the high-temperature-resistant cup cover, mirror surface treatment is performed on a contact face among the high-temperature-resistant cup cover, the high-temperature-resistant resistor heating body and the high-temperature ceramic cover plate to enable the contact face to be sealed, a compression airflow through hole is formed in the high-temperature ceramic cover plate and leads to the inside of the high-temperature-resistant cup cover, a through hole is formed at the bottom of the high-temperature-resistant cup cover, high-temperature hot airflow is sprayed to a steel member from the through hole, a metal sleeve is arranged on an outer column face of the high-temperature-resistant cup cover to prevent high-temperature explosion of the high-temperature-resistant cup cover from injuring people, and a water jacket, a water inlet and a water outlet are arranged on the outer layer of the metal sleeve.
Description
Technical field
The present invention and a kind of TURP cutter, specifically a kind of electric heating air-flow cutting head.
Background technology
At present, traditional plasma cutters can produce inclined to one side arc when cutting metallic plate, makes otch out-of-flatness.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric heating air-flow cutting head.
In order to solve the problems of the technologies described above, electric heating air-flow cutting head of the present invention, comprise high temperature resistant cup cover, high temperature resistant resistance heater, it is characterized in that, high temperature resistant resistance heater is fixed in high temperature resistant cup cover by refractory ceramics cover plate, do not contact with high temperature resistant cup cover, high temperature resistant cup cover, high temperature resistant resistance heater, contact-making surface between refractory ceramics cover plate is made specular surface and is processed, make contact-making surface sealing, a compressed air stream through hole is set on refractory ceramics cover plate, lead in high temperature resistant cup cover, high temperature resistant cup cover bottom arranges a through hole, high temperature hot gas stream sprays to steel part from through hole, on the outer cylinder of high temperature resistant cup cover, a metallic sheath is set, prevent that high temperature resistant cup from covering high temperature explosion and hurting sb.'s feelings, skin at metallic sheath is arranging a water jacket, and establish intake-outlet.
After being electrified to high temperature resistant resistance heater, heat rapidly the Compressed Gas of the high temperature resistant cup cover of constantly importing, make Compressed Gas become the high temperature gas flow of energy deposite metal, the through hole that covers bottom by high temperature resistant cup sprays to metallic plate, and it is cut.
Adopt the design's beneficial effect to be: electric heating air-flow cutting head of the present invention can make work piece cut smooth as flame cutting.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric heating air-flow cutting head of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, electric heating air-flow cutting head of the present invention is described in further detail.
