Abstract

A portable type welding machine which comprises a rack body of the machine, a transformer, several post heads and a joint circuit is characterized in that a primary coil comprises concatenation of two parts respectively winding around the upper portion of left and right pillars of an iron core and a secondary coil consists of concatenation of two parts winding around the lower portion of left and right pillars of the iron core. The ingenious employment of a structure that the primary coil and the secondary coil respectively wind around the upper and the lower portion of both the left and right pillars of the iron core effectively reduces the magnetic field eddy effect from the coil after electrified, thereby not only heat release but also noise and vibration of the transformer are lowered to enable the utility model to conveniently employ cheap shells made of sheet iron and effectively lower the cost of raw material and production on the basis of safely reaching national safety production standard in order to provide products with strong advantages in market competitions. The utility model has a simple structure, an excellent practicability and is easy to be manufactured.

Description

A kind of portable electric welding machine

Technical field

The utility model relates to a kind of electric welding machine, particularly a kind of portable electric welding machine that can be portable.

Background technology

Existing portable electric welding machine is not cover housing mostly, the iron core of its transformer and binding post all expose outside, the security of using is low, do not reach the basic security standard of country, present for this reason many producers all with housing with Rack Body and transformer upper shield and envelope, but because the primary coil and the secondary coil of the transformer of electric welding machine all are winding structure and the modes that adopts as shown in Figure 1, be about to primary coil and secondary coil be wound on separately respectively iron core on, on the lower frame post, in use because the magnetic field eddy current effect that primary coil and secondary coil produce because of energising, heating and generation shake and noise greatly easily, need housing is adopted relatively more expensive low magnetization stainless steel and adopts big extraction fan with heat extraction for this reason, and exhausting property ground suspends a period of time to avoid the overheated phenomenon of burning of transformer between in use often needing, increase the raw material and the manufacturing cost of electric welding machine so on the one hand, reduced the efficient of manipulating of equipment on the other hand.

Summary of the invention

The purpose of this utility model is the problem at above-mentioned existence, and a kind of simple and ingenious structure, with low cost, portable electric welding machine that efficient is high are provided.

The technical solution of the utility model is achieved in that

A kind of portable electric welding machine, comprise Rack Body, transformer and some binding posts and connecting circuit, wherein transformer is made up of the primary coil and the secondary coil that are wound on respectively on the iron core, iron core is fixed on the Rack Body, be characterized in that above-mentioned primary coil is composed in series by the two parts that are wound on the left and right side frame post of iron core top respectively, secondary coil is composed in series by the two parts that are wound on the left and right side frame post of iron core bottom respectively.

Wherein for effectively reaching national safety standard, above-mentioned portable electric welding machine also includes iron housing, and this housing upper shield envelopes Rack Body and transformer and connects as one with Rack Body.For ease of heat extraction be convenient to manipulate, above-mentioned portable electric welding machine also includes minitype axial flow fan and power supply indicator and current regulating switch, wherein the minitype axial flow fan device is on Rack Body, and a side position of respective shaft flow fan has the trellis air outlet on the housing, its opposite side correspondence has some horizontal stripe shape air inlets, and power supply indicator and current regulating switch device are on case panel.

The utility model is owing to adopt primary coil and secondary coil to be wound on the left side of iron core respectively dexterously, on the right frame post, the structure of bottom, lowered the magnetic field eddy current effect that coil produces because of energising effectively, both reduced the heat generation rate of transformer, noise and vibrations that transformer produces have been lowered again, make the utility model can adopt the housing that cheap iron sheet makes easily and adopt cheap minitype axial flow fan to come exhausting, make the utility model can reach on the basis of national security production standard reliably, effectively reduce raw material of the present utility model and production cost again, make product have stronger market competition advantage, and exhausting property ground suspends the phenomenon of a period of time with cooling between having avoided again in use wanting, improved operating efficiency of the present utility model greatly, and the utility model is simple in structure, make easily, practical.

Describe basic structure of the present utility model in detail below in conjunction with accompanying drawing:
