Embodiment 1

[0052] This embodiment provides a production process of an acetylene cutting nozzle, including the following steps:

[0053] (1) Using copper rods as raw materials, according to the set external dimensions and shapes, the raw materials are made into outer nozzle preforms and inner nozzle preforms using a cold heading machine. The outer nozzle preforms are cold forged to form a connecting platform, and the outer nozzle The preform is cold-headed to form a sleeve structure with a connecting groove;

[0054] (2) Further processing the inner nozzle preform, punch the center of the inner nozzle preform to obtain an oxygen flow mechanism, punch out the air inlet holes evenly at the air inlet end of the inner nozzle, and cut air grooves inward along the outer wall of the inner nozzle Connect with the air inlet;

[0055] (3) Sleeve the processed inner nozzle preform into the outer nozzle preform, the connecting table is embedded in the connecting groove, and the connecting table is punched ...

Embodiment 2

[0060] This embodiment provides a production process of an acetylene cutting nozzle, including the following steps:

[0061] (1) Using copper rods as raw materials, according to the set external dimensions and shapes, the raw materials are made into outer nozzle preforms and inner nozzle preforms using a cold heading machine. The outer nozzle preforms are cold forged to form a connecting platform, and the outer nozzle The preform is cold-headed to form a sleeve structure with a connecting groove;

[0062] (2) Further processing the inner nozzle preform, punch the center of the inner nozzle preform to obtain an oxygen flow mechanism, and evenly punch 6 air inlet holes through the connecting table at the air inlet end of the inner nozzle, and place them on the lower edge of the connecting table. Cut the air groove inward along the outer wall of the inner nozzle to communicate with the air inlet hole, and mill out 6 long grooves uniformly in the circumferential direction along the out...

Embodiment 3

[0068] This embodiment provides a production process of an acetylene cutting nozzle, including the following steps:

[0069] (1) Using copper rods as raw materials, according to the set external dimensions and shapes, the raw materials are made into outer nozzle preforms and inner nozzle preforms using a cold heading machine. The outer nozzle preforms are cold forged to form a connecting platform, and the outer nozzle The preform is cold-headed to form a sleeve structure with a connecting groove. At the outlet end of the outer nozzle preform, 6 long grooves are milled circumferentially along the inner wall of the preform, and the diameter of the long groove is larger than that of the set fire hole;

[0070] (2) Further processing the inner nozzle preform, punch the center of the inner nozzle preform to obtain an oxygen flow mechanism, punch out the air inlet holes evenly at the air inlet end of the inner nozzle, and cut air grooves inward along the outer wall of the inner nozzle Co...

Abstract

The invention discloses an acetylene cutting nozzle. An air inlet end is arranged at one end of the cutting nozzle, an air outlet end is arranged at the other end of the cutting nozzle, the air inletend is provided with an air inlet mechanism, the air outlet end is provided with a flame spraying mechanism, the cutting nozzle further comprises an oxygen flow mechanism, and the oxygen flow mechanism communicates with the air inlet end and the air outlet end. The acetylene cutting nozzle comprises an outer nozzle body and an inner nozzle body, the outer nozzle body sleeves the inner nozzle body,a mixed gas cavity is formed between the inner nozzle body and the outer nozzle body, and the mixed gas cavity communicates with the air inlet mechanism and the flame spraying mechanism. The oxygen flow mechanism is arranged in the inner nozzle body in a penetrating mode. The outer nozzle body is matched with the inner nozzle body to form a first sealing end and a second sealing end, and the flame spraying mechanism is arranged at the second sealing end. The invention further discloses a production process of the acetylene cutting nozzle, a copper rod is taken as a raw material, cold headingmachining is carried out first to obtain prefabricated parts of the outer nozzle body and the inner nozzle body, and forging machining is carried out after sleeving the prefabricated parts of the outer nozzle body and the inner nozzle body to integrate the prefabricated parts into an integral structure. The acetylene cutting nozzle is easy to machine and can spray flame with more uniform pressure.The acetylene cutting nozzle has the characteristics of less feeding and high machining speed, and the production cost is reduced.

Description

Technical field [0001] The invention relates to gas flame cutting, in particular to an acetylene cutting nozzle used for gas flame cutting and a production process thereof. Background technique [0002] Gas cutting is the use of combustible gas and oxygen mixed combustion to produce high temperature, preheat the metal to a molten state, and at the same time by means of high-pressure cutting oxygen flow to form a gas cutting seam, so as to achieve the purpose of metal cutting. Gas cutting technology is widely used in the metal cutting field of various manufacturing industries and other industries. Among them, the cutting nozzle, as a key component, has a vital impact on the performance of the entire cutting. [0003] Traditional cutting nozzles are generally made of brass or red copper. For example, the invention patent "A cutting torch cutting nozzle and its processing method" with the patent number CN200910155486.5 discloses a cutting nozzle processing method, including multiple t...
