[0002] The existing ZSF-1500 carbon arc gouging machine cutting equipment has unstable working voltage, fast temperature rise, and is prone to major safety hazards such as overload short circuit and electric shock, which seriously affects the normal progress of raw aluminum cutting and recycling work. In addition, there is a gap between the cutting device and the cutting carbon rod or the cutting temperature rises too quickly, which will cause the cutting device to burn during cutting, so that the cutting carbon rod cannot be clamped tightly, causing the carbon rod to slip and break frequently due to burning. Whenever the above situation occurs, the raw aluminum cutting work must be stopped, and the cutting device must be disassembled and re-welded and repaired before it can be operated again. This not only increases the consumables for cutting carbon rods, but also causes instability in the working of the cutting device. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention:

[0017] like Figure 1-4As shown, a carbon arc air gouging cutting device for aluminum under an aluminum reduction cell comprises a handle 2 and an anti-skid sleeve 3, one end of the handle 2 is sleeved with a clamping structure, which effectively clamps the carbon rod for gouging at a fixed angle; the other end of the handle 2 is sleeved with the anti-skid sleeve 3 to prevent construction workers from slipping during operation; an air duct 19 is welded parallel to the bottom end of the clamping structure; a rubber hose 20 is sleeved at one end of the air duct 19, which effectively aligns the air outlet (pressure 0.4-0.6MPa) at one end of the air duct 19 with the carbon rod clamp for continuous cooling, preventing the clamp from burning due to excessive temperature, and blowing the molten metal under the action of the carbon arc; a wiring hole 21 is provided on one side of the clamping structure.

[0018] Specifically, the clamping structure includes a connecting tube 1, a fixing part 4, a clip A5 and a clip B6; the interior of the connecting tube 1 is composed of an active cavity 17 and a sleeve 18, and one end of the sleeve 18 is sleeved with one end of the handle 2; a "U"-shaped fixing part 4 is welded to the front end of the connecting tube 1; a clip A5 is welded to the inner side of one end of the fixing part 4; a clip B6 is symmetrically arranged on the clip A5; a connecting rod 7 is welded to the rear end of the clip B6; a blocking piece a8 is vertically connected to the rear end of the connecting rod 7; a spring 9 and a blocking piece b10 are arranged in sequence on the rear end of the blocking piece a8; the rear end of the connecting rod 7 passes through the circular hole at the front end of the connecting tube 1, and the blocking piece a8, spring 9 and blocking piece b10 connected to the rear end are arranged in the active cavity 17, so that the operator can control the extension and retraction of the spring 9 to clamp the carbon rod.

[0019] Specifically, a slot 11 is provided at the upper end of the connecting part of the connecting rod 7 and the blocking piece a8; a long strip-shaped through hole 14 is provided at the upper front end of the connecting tube 1; two fixing plates 15 are provided on both sides of the through hole 14; the slot 11 is movably connected to the lower end of the pressure rod 13 through the first rotating shaft 12; the middle position of the fixing plate 15 is movably connected to the middle part of the pressure rod 13 through the second rotating shaft 16, and the operator moves the pressure rod 13 up and down to control the clamping piece B6 at the front end of the connecting rod 7 to cooperate with the clamping piece A5 to clamp the carbon rod.

[0020] Specifically, the clip A5 and the clip B6 are assembled to form a circular ring; a circular hole with an angle of 45° is provided between the clip A5 and the clip B6; and the diameter of the circular hole is 30 mm.

[0021] Specifically, the handle 2 is made of wood.

[0022] During use, the operator pushes the pressure rod 13 upwards, and the connecting rod 7 connected to the lower end of the pressure rod 13 squeezes the spring 9 backwards, and the clip B6 at the front end of the connecting rod 7 opens backwards. The staff places the carbon rod between the clips A5 and B6, and then the operator pushes the pressure rod 13 downwards, the connecting rod 7 is reset, and the clips A5 and B6 clamp the carbon rod at an angle of 45°. The operator then turns on the power through the wiring hole 21 and then performs the cutting operation. At this time, the air outlet of the air duct 19 at the bottom of the clamping structure is aligned with the carbon rod clamp for continuous cooling to prevent the clamp from burning due to excessive temperature, and to blow the molten metal under the action of the carbon arc.
