Abstract

The utility model designs a manual flame cutter. A flame cutting handle is fixed to a small gantry crane which is driven by hand and can walk on workpieces along desired traces. The utility model has the main structure that a lifting frame of which the height can be adjusted is arranged on the gantry crane with wheels. A rocking handle, a kettle wheel set, a chain wheel, a guiding chain, driven wheels, driving wheels, etc. are arranged on the lifting frame to form a transmission system. The horizontal regulation of a sliding bar, the vertical regulation of the cutting handle and an angle regulating device form a regulating system to regulate the horizontal distance, the vertical height and the inclined angle of a cutting nozzle to satisfy the requirement of the processing of the workpieces. The utility model is suitable for the processing of metal plates and pipes and has the advantages of simple structure, small volume, portability, simple operation, safety and strong applicability to environment.

Description

Hand flame cutter

The utility model belongs to the local heat cutting, as flame cutting, particularly a kind of hand-rail type flame cutting machine.

The main method of gas cutting metal pipe material and sheet material mostly adopts manual operations at present.And automatically and semi auto cutting machine,, can not be widely applied to the job site owing to exist complex structure, cost an arm and a leg, easy break-down, inconvenience maintenance, be subjected to shortcoming such as power limitations.Purpose of the present invention to produce a kind of between semi-automatic and hand-manipulated between, both possessed the cutting accuracy height of cutting machine, advantage of high production efficiency has realized the hand-rail type flame cutting machine that simple structure is small and exquisite, adaptability by force, is not subjected to power limitations again.

The hand-rail type flame cutting machine of the utility model design, be with cut down by oxygen inlet, acetylene inlet, pure oxygen, oxygen adjusting valve, acetylene cut down, cut and the flame cutting that constitutes such as chew being fixed on the small arc shaped crane.The concrete structure of this car is: constituted portal frame, and four driven pulleys are housed below the chassis by chassis, two door pillars, door beams; Two ends are enclosed within on two door pillars, and are on the track suspension bracket that can slide up and down with the door pillar, and the pot wheel set of available wind transmission is housed, the sprocket wheel that rotates with the pot wheel and lead chain; Lead the chain drive driving wheel corresponding and on the track of machining sheet, walk, or relatively rotate with the tubing that drives processing with driven pulley; It is to lead chain for tension that the lifting of suspension bracket is slided, and its slip is by a lower end and suspension bracket flexible connection, vertically passes a beam, there is a screw knob upper end, is with that the suspension rod of support spring finishes; Paperback sliding thick stick on the chassis, cuts promptly being fixed on its termination, smoothly moves sliding thick stick by a Heibei provincial opera knob, cuts the distance of chewing with adjustment; On the dop that sliding thick stick one end fixedly cuts, there is adjusting to cut the vertical tuning knob and the recliner of chewing vertical height and inclination angle.

The hand-rail type flame cutting machine of this utility model design has that simple structure, volume are small and exquisite, light, cutting accuracy and high efficiency, simple to operate, advantage such as environmental suitability is strong, is specially adapted to the site operation of metal blanking.

Description of drawings: Fig. 1 is the front view of hand-rail type flame cutting machine; Fig. 2 is the side view of hand-rail type flame cutting machine.

Specify the embodiment of hand-rail type flame cutting machine of the present utility model in conjunction with the accompanying drawings:

Embodiment 1:

The hand-rail type flame cutting machine is to cut down (4) by oxygen inlet (5), acetylene inlet (6), pure oxygen, to transfer oxygen to cut down (7), cut and chew cutting being fixed on the portal jib crane that (1) constitute.The structure of this car is: constituted portal frame by chassis (22), two door pillars (20), door beam (10), and the both sides of adorning four driven pulleys (23), suspension bracket (9) below the chassis are enclosed within on two door pillars (20), and slide up and down the sprocket wheel (17) that the pot wheel set (18) of available rocking handle (16) transmission is housed on the suspension bracket (9), rotates with the pot wheel and lead chain (19) along the door pillar track; Lead chain (19) and drive and guide rail (25) the upward walking of the corresponding driving wheel of driven pulley (23) (24), or the tubing (26) of drive processing relatively rotates in machining sheet (26); It is to lead chain (19) for tension that the lifting of suspension bracket (9) is slided, and its slip is to finish by a lower end and suspension bracket (9) flexible connection, the vertical suspension rod (11) that passes a beam (10), upper end and have a screw knob (12), centre to be with support spring (13); (22) are gone up paperback and sliding thick stick (21) on the chassis, cut promptly being fixed on its termination by a dop, smoothly move sliding thick stick (21) by Heibei provincial opera button (8), reach the effect of chewing (1) distance of cutting of adjusting, can adjust by recliner (3) and to cut the inclination angle of chewing (1), can adjust by vertical tuning knob (2) and cut the height of chewing; Acetylene conduit (14) and acetylene are regulated and are cut down (15) and be installed in a end on the beam (10).

Embodiment 2:

As embodiment 1 described hand-rail type flame cutting machine, when its processing pipe material (26), then do not need driving wheel (24) and guide rail (25), promptly Jia Gong tubing (26) has substituted driving wheel (24), and chain (19) directly drives tubing and driven pulley (23) relatively rotates by leading.
