Abstract
The utility model relates to a carbon arc gas gouging device, relating to automatically feeding carbon rods. The body of the device is provided with a micro motor directly dragging carbon rod feeding rollers and a hold-down mechanism being composed of a hold-down cap, a spring, a bracket and a hold-down roller. Under the gas gouging course, carbon rods are automatically and uniformly feed in by using the holding function of two rollers and the rotary movement of carbon rod feeding rollers and the distance between carbon rods and work pieces is not adjusted at any time so that gouging quality is improved. The device is arranged at gas cutting machines or welding machines to enlarge the working range of the two machines.
Description
The utility model relates to the carbon arc cutting device, particularly the carbon arc air gouging device of carbon-point automatic feed.
Before the utility model proposes, when carrying out carbon arc air gouging and carbon arc air cutting work, all adopt hand-held carbon arc air gouging rifle." welder's handbook " (manual welding and cutting part, the group of writing writes by welder's handbook, China Machine Press publishes, in March, 1975 Beijing front page) among the P294, disclose a kind of circumference blast type gouging torch, it is by the nozzle nut, the distinguish collet, the mouth body, insulator cap, conduction breather pipe, gas-tpe fitting, cable connector and insulation are cut down, and automatic switch is formed.The distinguish collet of this gouging torch has plurality of specifications, can adapt with the carbon-point of different-diameter.When adopting this gouging torch to carry out the gouge operation, after compressed air blows out along carbon-point through the square air-out groove on the distinguish collet, slag blown out from the both sides of groove and can not be deposited in the front end of channeling, be convenient to see clearly the planing direction, also make carbon-point obtain cooling simultaneously.In the gouge operation process, carbon-point needs constantly to adjust the carbon-point extension elongation and change carbon-point constantly by scaling loss, guarantees normal operation, so just must often stop planing operation.In order to make arc stability and to obtain uniform planing cutting speed, operating personnel not only will control the speed that gouging torch is pushed ahead well, control the feed rate of carbon-point again well.Can not make the long fluctuation of service that makes of electric arc, even blow-out; Can not make electric arc too short again, being short-circuited so that the carbon-point head is run into workpiece makes arc extinction, causes " folder carbon " defective.This artificial carbon-point is sent mode to, often is difficult for reaching the uniform purpose of speed, will interrupt planning operation when not only changing carbon-point; And in operation process, constantly adjust the distance of carbon-point and workpiece, and can make the track of gouge or cutting directly not slick and sly, also easily dig partially.Labor intensity of operating personnel is also bigger.
The purpose of this utility model is: overcome above-mentioned weak point of the prior art and provide a kind of carbon arc air gouging device that can the automatic feed carbon-point.
Realization the utility model can be taked following technique measures.On the body of carbon arc air gouging device, except air duct interface and the carbon-point that should arrange inserts the mouth, also be provided with a pair of columned roller, this pair roller is arranged in the below of carbon-point mutually symmetrically, and closely contacts with carbon-point.Roller below carbon-point is that carbon-point is sent wheel to, and it is directly installed on the main shaft of micro motor, and this micro motor also is installed on the body of carbon arc air gouging device.At the roller of sending on the wheel symmetric position with carbon-point above the carbon-point is contact roller, and this contact roller is installed in and compresses in the support, compresses support and is connected with clamping cap by spring, and this clamping cap is with the mode and the body relative fixed that are threaded.Clamping cap, holddown spring compresses support and wheel shaft, and contact roller is formed a hold-down mechanism.The relative position of adjusting clamping cap just can and compress support by spring and adjust the compression clamping degree of contact roller to carbon-point.When connecting the power source of micro motor, motor will directly drive carbon-point and send the wheel rotation to, because carbon-point is by the compression clamping of above-mentioned pair roller institute, the rotation that former carbon-point is compressed into wheel will drive carbon-point and constantly stretch out forward, obtain uniform carbon-point feed rate, the distance of carbon-point and working surface also can guarantee constant.
For with carbon-point more effectively clamping avoid skidding, two rollers all can be made with oil resistant rubber; Also can promptly make recessed circle with the carbon-point contact portion in the side of cylindric roller, formed circular section, the involutory back of two rollers should be complementary with the cross section of carbon-point.
On the utility model, handle can be set, become the carbon arc air gouging device of hand-held carbon-point automatic feed.The parts that are fixedly clamped of open circles pass also can be set, extremely easily device be fixed on gas cutting machine or the bonding machine, and carbon-point stretches out direction and carbon-point and workpiece planarization initial distance adjustable size.
The employed micro motor of the utility model can be to be the gas motor of power source with gas, also can be with electric power be power source raise the clothes motor, drive micro cell etc.Only 1-5 rev/min of rotating speed.
When adopting the utility model to carry out planning operation, operating personnel are as long as adjust the angle position of carbon-point and the distance of carbon-point and workpiece planarization when operation begins.Just can be primarily focused on the distance that needn't adjust carbon-point and workpiece planarization on the planing gait of march at any time when carrying out operation, also needn't take the carbon-point feed rate into account, labour intensity is alleviated.The carbon-point automatic feed has been avoided because the long or too short caused defective of electric arc has improved such as back chipping groove processing, the planing quality of cutting and so on.After being fixedly mounted on the utility model on gas cutting machine or the bonding machine, just can realize the automation of gouge and carbon-point air cutting, enlarged the cut coverage of gas cutting machine, except that butt welded seam carries out back chipping and planing, all right cutting stainless steel, can process J type bevel for welding to steel plate, can also remove to carry out planning operation to the narrow and small place that manually can't arrive.
