Plasma flame cutting machine with cooling protection device

Abstract

The invention discloses a plasma flame cutting machine with a cooling protection device. The machine comprises a protective frame, a threaded sliding block, sliding plates, sliding groove holes, guide columns and track sliding grooves, the top end of the protective frame is fixedly connected with a protection motor, a protective screw rod used for driving the threaded sliding block to horizontally slide is arranged at the output end of the protective motor, and two sets of connecting rods used for driving the two sets of sliding plates to horizontally and relatively slide are rotationally connected to the two sides of the top end of the threaded sliding block correspondingly. According to the plasma flame cutting machine with the cooling protection device, by arranging a protective plate, in the protective frame, the threaded sliding block drives two sets of sliding plates to horizontally and relatively slide through two sets of connecting rods, so that the sliding plates move to drive two sets of guide columns to horizontally and relatively slide along two sets of track sliding grooves through two sets of sliding groove holes, the guide columns move to drive rotating rods to rotate, the rotating rods rotate to drive the protective plate to slide along the side wall of the protective frame, and protection operation on an injection opening is achieved.

Description

technical field [0001] The invention relates to the field of flame cutting machines, in particular to a plasma flame cutting machine with a cooling protection device. Background technique [0002] Flame cutting machine is a kind of cutting equipment that uses gas with oxygen or gasoline with oxygen to cut metal materials. It is mainly used in heavy industry. Plasma cutting uses the heat of plasma arc to melt part of the metal of the workpiece incision, and borrows the momentum of high-speed plasma A processing method that excludes molten metal to form an incision. Its main advantage is that it can cut all kinds of metals that are difficult to cut with oxygen by cooperating with different working gases, especially for non-ferrous metals. Therefore, plasma cutting is Widely used in automobiles, pressure vessels and other fields. [0003] However, the existing plasma flame cutting machine has the problem of not performing protective operations during use, which leads to a grea...
