Abstract
The invention discloses a pneumatic height regulating device of a cutting torch for an advertisement cutting machine, comprising a cutting torch, a cutting torch fixing board, an air cylinder, a stepping motor, a cutting gun fixing board, an air cylinder support, an air cylinder nut, a gun head, a plasma spacer sleeve, a cutting gun clamp sleeve, a motor base and the like. The gun head is provided with a plasma gun head copper sleeve and the plasma spacer sleeve, and a cooling water inlet and a cooling slot are arranged on the plasma gun head copper sleeve. A fixed distance is formed between the gun head and the bottom surface of the plasma gun head copper sleeve and is an optimum cutting-flame height, and the bottom surface of the plasma gun head copper sleeve is fully in contact with a steel board when the cutting torch drops. The plasma spacer sleeve is fully separated from the cut board by the plasma gun head copper sleeve so that the plasma spacer sleeve is effectively protected. In a cutting process, cooling water enters the cooling slot through the cooling water inlet and is sprayed on the cut board by a cooling water spraying port to lower the temperature of the cut board, thereby effectively preventing the cut board from deforming at high temperature.

The specific embodiment
The specific embodiment of the present invention is such, shown in Fig. 1-6, this device comprises cutting torch, cutting torch fixed head 1, cylinder 2, stepper motor 3, burning torch fixed head 4, cylinder support 5, cylinder nut 6, plasma gun head copper sheathing 7, rifle head 12, plasma spacer sleeve 13, burning torch chuck 14, motor cabinet 15, crossbeam tooth bar 16, crossbeam 17 etc.Stepper motor 3 gears and 16 engagements of crossbeam tooth bar, crossbeam tooth bar 16 is installed on the crossbeam 17.Cutting torch carries out the Z-direction location by the dovetail groove moving guide rail under the drive of cylinder 2.Burning torch is clamped by burning torch chuck 14, burning torch chuck 14 is connected with burning torch fixed head 4 by bolt, cylinder support 5 is installed on the burning torch fixed head 4, cylinder support 5 is connected with cylinder piston by nut, when Compressed Gas enters cylinder, cutting torch upwards lifts under the driving of cylinder piston, when discharging cylinder, Compressed Gas falls under the effect of cutting torch at self gravitation, because rifle head 12 is constant with the distance of plasma gun head copper sheathing 7 bottom surfaces, when cutting torch falls plasma gun head copper sheathing 7 bottom surfaces be cut sheet material and contact fully, therefore when cutting torch falls the same pattern of cutting fully, plasma gun head copper sheathing bottom surface and sheet material are permanently connected to, and the rifle head has pre-set a segment distance from plasma gun head copper sheathing bottom surface, and this distance is the optimum height of cutting flame promptly.
The course of work of the present invention is as follows: in the process of work, cutting torch is mainly along the X-direction of crossbeam 17, the Y direction of workbench two side rails and vertical Z-direction, and X-axis, Y-axis and Z-direction are vertical mutually in twos.Cutting torch fixed head 1 is connected with rail plate by slide block, cutting torch is positioned at the Z-direction state by the dovetail groove moving guide rail under the drive of cylinder 2, cutting torch is in X-direction mobile status on the crossbeam by rack-and-pinion under the driving of stepper motor 3, cutting machine moves up and down along Z-direction under the driving of described cylinder 2.
In the process of cutting pattern, cooling water does not stop sprays to sheet material, after having cut a pattern, burning torch is flame-out, cooling water stops to spray, cutting torch lifts under the driving of cylinder piston simultaneously, cutting torch moves under the driving of stepper motor 3 and two side rails stepper motors then, realize the initial alignment of next pattern, when discharging cylinder, Compressed Gas falls under the effect of cutting torch at self gravitation, begin igniting cutting, spray cooling water simultaneously, repeat above-mentioned action again and cut next pattern until having cut this figure.
