Description

eleven

The invention relates to the machining of metals with heating and can be used in planers.

The purpose of the invention is to reduce the metal capacity and increase productivity by reducing changeover time, g

Figure 1 shows the device, a general view; FIG. 2 is view A of FIG. on fig.Z - view In figure 1.

A plasma torch 3 and a rod 4 are mounted on the tool holder 1 with the tool 2, carrying an adjustable stop 5 “Satellite anode 6, performed as a set of refractory elements, for example graphite, fixed to. the carriage 8, on which the guide 9 is also installed. The carriage 8 is arranged to move horizontally on two rods 10, which in turn are mounted to move on vertical guides 11 mounted on the table 12 of the machine. Adjusting the position of the carriage 8 on the vertical guides 11 is carried out by means of the clutches 13. In the carriage 8, a brake 14 is placed, preventing it from

against the workpiece 15,

The device works as follows.

During the working stroke, the plasma arc heats the metal layer being cut off. At the end of the working stroke, the stop 5, acting on the guide 9, displaces along the guides 11 the carriage 8 with the anode: -satellite 6 by the feed amount, aligning the plane. refractory elements 7 with a cutting plane. As a result, the plasma arc is transferred from the machined part 15 to the refractory elements 7 of the satellite anode 6. When idling, the plasma arc moves over the satellite anode 6 and then above the machined part 15. By heating the metal layer that is cut off during working course. The idle speed of the table 12 of the machine is significantly higher than the cutting speed, which eliminates strong heating of the part when idle. The cycle of operation is repeated. In the case of the burn-through of one or several refractory elements 7 of the satellite-anode 6, these refractory elements are carried out.
