Problems solved by technology

Although hpb59-1 lead brass has good machinability, it is easy to oxidize and corrode when it encounters various components in the gas, which will easily lead to the change of the nozzle hole diameter of the gas stove nozzle made of lead brass, and then affect As far as the product performance of the gas stove nozzle is concerned, the thermal efficiency of the gas stove will be greatly reduced, and the carbon monoxide emission will be greatly increased. If the gas stove nozzle is made of stainless steel, the above problems can be solved well , but due to the high hardness of the stainless steel material, the aperture of the nozzle hole is very small, usually between φ0.3mm-φ1.5mm, that is to say, the straight drill used for cutting the nozzle hole of the gas stove is very fine , so if the above-mentioned processing method is still used to drill the nozzle hole on the stainless steel nozzle body, the straight drill will easily break, resulting in the inability to complete the drilling nozzle hole

Embodiment 1

[0041] Such as figure 1 and image 3 shown to manufacture figure 1 Taking the stainless steel nozzle of the gas stove as an example, the manufacturing method of the stainless steel nozzle of the gas stove of the present invention comprises the following steps:

[0042] Use an electric heater to heat the stainless steel material to 300-1000°C. The specific heating temperature can be determined according to different types of stainless steel materials. The main purpose of this step is to soften the stainless steel material so as to greatly reduce the impact on the stainless steel material. The wear of the extrusion die improves the service life of the extrusion die. Of course, the temperature of the stainless steel material should not be too high to avoid oxidation of the stainless steel material at high temperature. The purpose of setting the heating upper limit temperature in this step is also based on this;

Embodiment 2

[0050] Such as figure 1 and Figure 4 shown to manufacture figure 1 Taking the stainless steel nozzle of the gas stove as an example, the manufacturing method of the stainless steel nozzle of the gas stove of the present invention comprises the following steps:

[0051] The stainless steel nozzle body with gas channel is processed with stainless steel material, specifically: the stainless steel material is fed into the multi-station cold heading machine, and the multi-station cold heading machine extrudes the stainless steel nozzle body with gas channel, stainless steel The nozzle body also has the outer circular surface of the gas outlet and the outer hexagon part formed together with the stainless steel nozzle body, and the stainless steel nozzle body reserves a position for drilling the nozzle hole at the axis of the gas channel to reduce extrusion. Difficult to design the die, to ensure the low roughness of the gas channel, the stainless steel material can be extruded by...

Embodiment 3

[0058] Such as figure 1 and Figure 4 shown to manufacture figure 1 Taking the stainless steel nozzle of the gas stove as an example, the manufacturing method of the stainless steel nozzle of the gas stove of the present invention comprises the following steps:

[0059] The stainless steel nozzle body with gas channel is processed with stainless steel material, specifically: the stainless steel material is fed into the multi-station cold heading machine, and the multi-station cold heading machine extrudes the stainless steel nozzle body without gas channel, The stainless steel nozzle body has the outer circular surface of the gas outlet and the outer hexagonal part formed together with the stainless steel nozzle body. The number of stations of the multi-station cold heading machine can be 2 to 4 stations, which can be determined according to the production of gas stove stainless steel. The size and style of the nozzle are determined; the gas channel is turned on the stainles...

Abstract

The invention relates to a manufacturing method of a stainless steel jet nozzle of a gas stove. The manufacturing method is characterized by comprising the following steps that a stainless steel material is heated to 300-1000 DEG C; a stainless steel jet nozzle body with a gas channel is machined with the stainless steel material; a central positioning hole used for conducting centralized positioning on a straight drill is machined in the stainless steel jet nozzle body, and the straight drill is used for drilling a nozzle hole; the nozzle hole is drilled in the stainless steel jet nozzle body through the straight drill, in the whole nozzle hole drilling process, the stainless steel jet nozzle body and the straight drill keep rotating coaxially, and the rotation direction of the stainless steel jet nozzle body is opposite to that of the straight drill; and an air inlet is formed in the stainless steel jet nozzle body through turning. The manufacturing method has the advantage that the jet nozzle of the gas stove can be manufactured with the stainless steel material.

Description

technical field [0001] The invention relates to the technical field of burner nozzles, in particular to a method for manufacturing a stainless steel nozzle of a gas stove. Background technique [0002] The gas stove nozzle generally includes a body, the body is provided with a nozzle hole and a gas channel, the nozzle hole communicates with the gas channel, one end of the body is provided with an air inlet connection part, and the other end of the body is provided with a gas outlet connection part. Existing gas stove nozzles are usually processed by hexagonal copper rods made of hpb59-1 lead brass. The processing steps are: first cut a section from the hexagonal copper rods as the body, and then turn the body to produce gas The channel, the connection part of the air inlet end, the connection part of the gas outlet end and the nozzle hole, a section of hexagonal part is reserved on the outer peripheral wall of the body. hole. Although hpb59-1 lead brass has good machinabil...
