Description

Technical Field

[0001] The utility model relates to the technical field of plasma cladding guns, in particular to a multi-angle plasma cladding gun powder spraying device. Background Art

[0002] The plasma cutting gun is a processing method that uses the heat of a high-temperature plasma arc to partially melt the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to discharge the molten metal to form a cutting seam. It is widely used due to its fast cutting speed, high cutting accuracy, easy setting of cutting conditions, easy automation, unmanned operation and relatively low cost.

[0003] After the plasma cutting gun in the prior art is used, it is necessary to perform a powder spraying process on the cutting part so that the end face of the cutting part can be effectively protected. In the prior art, the powder spraying equipment is usually manually operated for spraying. Due to the low stability of manual hand-holding and the simple structure of the powder spraying equipment, the angle of powder spraying will be directly affected when the angle is manually adjusted, resulting in the cutting part not being completely covered by powder, but repeatedly spraying powder, thereby increasing the cost of using powder.

[0004] Therefore, we designed a multi-angle plasma cladding gun powder spraying device. Utility Model Content

[0005] The utility model aims to provide a multi-angle plasma cladding gun powder spraying device in order to solve the problem of low stability in the prior art.

[0009] Preferably, the rear cover is matched with the rotating wheel, and the rear cover abuts against the straight pipe.

[0010] Preferably, both ends of the fixed shaft are fixedly connected to the rear cover via fasteners, a clamping piece is provided on the fixed shaft, the fixed shaft is rotatably connected to the clamping piece via a brake ring, and the brake ring is fixedly connected to the fixed shaft.

[0013] The beneficial effects of the utility model are:

[0014] The utility model can adjust the angle of the powder spraying device vertically by setting a fixed shaft and a clamping part, thus avoiding the deficiency of low stability when holding manually. Compared with the prior art, the instability during manual angle adjustment can be reduced, and the accuracy of angle adjustment can be improved by the brake pipe, thus avoiding uneven manual adjustment force, resulting in large or small angles, and making it impossible to align the angle of the powder spraying device with the cutting component, thereby reducing the cost of using powder.

[0015] The utility model provides a rotating wheel so that the powder spraying equipment can adjust the horizontal angle without destroying the original vertical angle, which not only improves the diversity of the equipment but also can cope with powder spraying work in different scenarios. Compared with the prior art, the functionality of the powder spraying equipment can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS
