Description

The novel portable electric welding machine

The utility model is the improvement for electric welding machine manufacturing equipment, exactly is the new-type design for a kind of small portable electric welding machine.

At present, at home and abroad in the building iron knot manufacturing multifunction electric welding machine weld system.And the electric welding machine volume of original usefulness is big, heavy, cost is high, consumed power is many, use is inconvenient, so the user wishes to have the small electrical welding machine to replace, preferably can design that some are carried, small and exquisite, durable portable electric welding machine.The small electrical welding machine that can carry once appearred on the market, but this electric welding machine since in the manufacture process tap more, the coiling trouble, so manufacturing cost is higher, so this product is eliminated gradually.

The purpose of this utility model is according to the shortcoming that exists in the problems referred to above, for the user provides a kind of new-type novel portable electric welding machine simple, easy to use of can carrying and make again.

The utility model is made up of frame 9, transformer 7, ventilating fan 8 etc.; Its technical essential is: the two ends of frame 9 are metal ends, it with four little lumps of wood between be to be connected by screw, between the little lumps of wood of upper and lower side and the little lumps of wood is to be connected by stay bolt, transformer is fixedly mounted in the frame, the drive end bearing bracket top of frame is fitted with four primary connection posts, four secondary connection posts are installed in the bottom, and equipped ventilating fan 8 on the rear end cap of frame is installed four castors 11 in the bottom of frame.

After the utility model is realized, can be widely used in steel construction electric welding field, compared with the prior art than the utility model following advantage is arranged: volume is little, in light weight, power big, be suitable for that the model circle is wide, life-span length, use, easy to carry.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is transformer circuit figure of the present utility model.

Among the figure: 1-secondary connection post, 2-primary connection post, 3-screw, 4-bolt, the former coil of wire of 5-, 6-by-pass volume, 7-transformer, 8-ventilating fan, 9-frame, 10-end cap, 11-castor.

Embodiment: in the utility model, 2 of rack section end caps, the thick 1mm of material, size 250mm * 180mm, 4 of the little lumps of wood, pine, size 40mm * 40mm * 300mm; 4 on bolt, size φ 10 * 150mm; One of ventilating fan, bore 120mm; Four on secondary connection post, the brass screws of φ 8, four on primary connection post, the brass screws of φ 6; 265 of transformer silicon steel sheets, thick 0.3mm, size 40mm * 90mm, 40mm * 230mm each half; The former coil of wire: 1-3 is 331 volumes; 1-2 is 206 volumes, and line footpath φ is 2.0mm; Secondary coil 4-5 is 40 volumes; 6-7 is 7 volumes, and the cross section is 2.2mm * 7mm, and said elements and part are assorted the back and installed by Fig. 1, Fig. 2 and get final product through debugging.

Claims
