Problems solved by technology

[0002] In the field of machinery, the spray head for spraying nano-scale collagen solution on the strip metal surface generally uses titanium alloy material as the base material, because titanium alloy can increase the wear resistance and corrosion resistance, but the production cost of using titanium metal as the base material is high , and the processing is difficult and the precision is not high
The structure of the nozzle in the prior art is complicated, it is difficult to control the spraying thickness, and the utilization rate of the heat source is not high
Most of the nozzles are non-detachable overall structures, which are inconvenient to inspect and replace, and there are many processing steps, which increase the cost of use

Embodiment 1

[0040] See figure 1 and figure 2 , figure 1 is the front view of the precision nozzle, figure 2 is a sectional view. In this embodiment, the shower head body includes an upper piece 1 and a lower piece 2 , which are fixed through bolts 3 , assuming that the heat source enters from the upper piece 1 and exits from the lower piece 2 .

[0041] A heat source passage 11 is provided on the side of the top sheet 1 close to the nozzle 7, and the heat source passage 11 runs through the top sheet 1 horizontally. A side of the lower sheet 2 near the nozzle 7 is provided with a lower sheet heat source channel 21 , the lower sheet heat source channel 21 runs through the lower sheet 2 horizontally, and a heat source outlet 22 is located at one end of the lower sheet heat source channel 21 . The other end of the heat source channel 11 of the upper piece and the other end of the heat source channel 21 of the lower piece are connected through a connecting pipe 4, and the connecting pipe...

Embodiment 2

[0046] The processing technology of the precision nozzle described in embodiment 1, comprises the following steps:

[0047] (1) Hot die forging after cutting the corrosion-resistant steel;

[0048] (2) The shape of the upper piece 1 and the lower piece 2 of the nozzle body is roughly machined by wire cutting technology;

[0049] (3) Drill and tap the upper piece 1 and the lower piece 2 and cut the buffer groove 6. The buffer groove 6 has a width of 6-12mm and a thickness of 0.002-0.010mm;

[0050] (4) After checking the size, coarsely grind and finely grind the joint surface of the upper piece 1 and the lower piece 2, so that the precision of the joint surface of the upper piece 1 and the lower piece 2 reaches 14 grades;

[0051] (5) Fix the upper piece 1 and the lower piece 2 with bolts 3, and correct the shape and position tolerance;

[0052] (6) Disassemble the upper piece 1 and the lower piece 2, vacuum titanium plating on the joint surface, chrome plating on the outer s...

Abstract

The invention discloses a precise nozzle. A nozzle body consists of an upper member and a lower member, wherein the upper member and the lower member are fixed by a bolt; one inner sides of the upper member and the lower member adjacent to the nozzle are respectively provided with a heat source channel, and the heat source channels horizontally penetrate the upper member and the lower member and are parallel to each other; a glue solution fluid hole is arranged inside the lower member, a buffer tank is arranged between the glue solution fluid hole and the nozzle, the buffer tank and the nozzle are located on a combined surface between the upper member and the lower member, the heat source channels of the upper member and the lower member are located at the two sides of the buffer tank, and a heat source heats a glue solution which passes through the buffer tank. The invention further provides a processing technology of the precise nozzle. The nozzle has the advantages that the nozzle body is set to be the upper member and the lower member, so that the nozzle body can be conveniently assembled and disassembled, and the processing technology is simple; a corrosion-resisting steel is served as a base material, so that the material cost can be greatly reduced; furthermore, the combined surface between the upper member and the lower member is a vacuum titanizing layer, so that wearing quality and corrosion resistance can be improved; and the spraying thickness can be controlled by the buffer tank, the precision is high, the use ratio of the heat source of the nozzle is high, and energy conservation and environment protection can be realized.
