Abstract

The utility model discloses an automatic ignition torch for cutting and welding, and the external fire source is no need. The utility model solves the igniting problem of the defect in existing cutting and welding torch. The utility model is characterized in that a trigger is arranged on the handle position made by insulating materials, and a piezoelectric ceramics igniter is installed tightly against the trigger. The body of the ignition torch for cutting and welding is provided with an alkyne valve, and a jet nozzle is arranged on the anterior part of the body of the ignition torch for cutting and welding. The ignition torch for cutting and welding not only no need the external fire source such as the match, etc., but also no need to install the battery or other power supplies, and can automatically ignite. The utility model has the advantages of simple structure, convenient operation and high safety.

Description

Automatic ignition torch for cutting and welding

The utility model provides a kind of external burning things which may cause a fire disaster that do not need, the welding torch that can light a fire automatically.

Currently used welding torch all relies on external burning things which may cause a fire disaster igniting such as match, lighter, igniter.This results in hand cramps for welding worker's operation.Because the welding torch scope of application is wide, mobile operational process is many, so to the keeping of match etc., carry certain difficulty, lose, make moist, damage through regular meeting.Hand was worn safety and industrial gloves when the welding worker operated, and igniting is inconvenience very.Especially in work high above the ground, dangerous more.

The utility model provides a kind of external burning things which may cause a fire disaster that do not need, the welding torch that can light a fire automatically.It has solved the self-brazing cutting torch come out since a unsolved always igniting difficult problem.The welding worker needn't carry external burning things which may cause a fire disaster such as match, does not also need to be equipped with battery or other power supply, can light a fire automatically.And it is simple in structure, easy to operate, safe and reliable.

The utility model is achieved in that the handle part of making at insulating materials, adorns a plate machine, adorns a piezoelectric ceramic ignitor spare near the plate machine, and its lead-out wire connects the metal torch body of welding torch.During igniting, open the acetylene valve of welding torch, enter an amount of acetylene gas, the jet of welding torch is aimed at the metal works 1-10m/m that the ground connection performance is arranged, pull the plate machine.Change by plate machine angle, piezoelectric ceramic ignitor spare has been produced certain pressure, the instantaneous pressure electricity that piezoelectric ceramic ignitor spare is sent is given the metal torch body of welding torch through lead-out wire, arrive jet, because jet faces the metal works 1-10m/m of ground connection performance, just jet and and metal works between produce electric spark, simultaneously, the acetylene gas that jet is discharged is lighted under the effect of electric spark.Realized that the welding torch lights a fire automatically.

The utility model also has standby hole, when not having the metal works of ground connection performance in the workplace, and an available plain conductor such as copper arc welding electrode, iron wire or electric wire, an end inserts standby hole, and the other end is pulled the plate machine apart from crater 1-10m/m, and same the realization lighted a fire automatically.

Below be accompanying drawings the utility model specific embodiment: (accompanying drawing 1 is the schematic diagram of auto-ignition welding torch)

A plate machine (1) is adorned at the handle that insulating materials is made (8) position, adorn a piezoelectric ceramic ignitor (2) near plate machine (1), the lead-out wire (3) of piezoelectric ceramic ignitor (2) connects metal torch body (4), handle (8) rear end lower is opened a standby hole (9), torch body (4) has an acetylene valve (5), and torch body front end has a jet (6).When needs are lighted a fire, open acetylene valve (5), enter an amount of acetylene, with jet (6) alignment pieces (7) 1-10m/m, pull plate machine (1), make it piezoelectric ceramic ignitor (2) is produced certain pressure, the instantaneous pressure electricity that piezoelectric ceramic ignitor (2) sends flows to torch body (4) through lead-out wire (3) and arrives jet (6), because workpiece (7) is in the 1-10m/m scope with jet (6), just produce electric spark, the acetylene gas of discharging jet (6) is lighted, finished igniting.When the workplace does not have ground connection workpiece (7) or built on stilts operation, can adopt plain conductor to insert standby hole (9), the other end is linked jet (6) 1-10m/m, pulls the plate machine, finishes igniting.

Claims

A kind of welding torch that can light a fire automatically, it is characterized in that: a plate machine (1) is adorned at the handle that insulating materials is made (8) position, adorn a piezoelectric ceramic ignitor (2) near plate machine (1), the lead-out wire (3) of piezoelectric ceramic ignitor (2) connects metal torch body (4), handle (8) rear end lower is opened a standby hole (9), torch body (4) has an acetylene valve (5), and torch body front end has a jet (6).
