Abstract
The utility model relates to the production technology of transformers, in particular to a fixing bolt for a plasma cutting machine transformer. Because the surface of the middle of the bolt is provided with a layer of non-magnetized materials, the magnetic path is effectively blocked, the leakage reactance is reduced, and the efficiency is improved.
Description
Technical field
The production technology of the utility model transformer, specifically a kind of fixed screw rod for plasma cutting machine transformer.
Background technology
When producing plasma cutting machine transformer, need utilize screw rod to fix.In the prior art, utilize screw rod made of iron and nut usually, because plasma cutting machine transformer belongs to high-leakage impedance transformer with the transformer fix tightly, therefore, thisly utilize the screw rod that pure iron makes there are the following problems fixedly the time: leakage reactance is big, and loss is big, efficient is low, temperature rise, and machine life is short.
Summary of the invention
The purpose of this utility model is to design a kind of fixed screw rod for plasma cutting machine transformer, owing to be provided with one deck non-magnet material at the middle section surface of screw rod, has blocked magnetic circuit, has reduced leakage reactance, has improved efficient.
The technical scheme that provides according to the utility model is provided with one deck layer of non-magnetic material at the middle section surface of screw rod body.
Described layer of non-magnetic material is a copper alloy layer.
Utilize screw thread to interconnect between described layer of non-magnetic material and the screw rod.
The polygon cylinder that is shaped as hollow of described layer of non-magnetic material.
The utility model has the advantages that: owing to be provided with one deck non-magnet material, blocked magnetic circuit, reduced leakage reactance, improved efficient at the middle section surface of screw rod.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Embodiment
As shown in the figure: the middle section surface at screw rod body 1 is provided with one deck layer of non-magnetic material 2.Two ends remain common iron screw rod.And external screw thread 3 is set respectively at the stage casing and the two ends of screw rod body 1.
Described layer of non-magnetic material 2 is a copper alloy layer.
Utilize the external screw thread 3 that is positioned at the stage casing to interconnect between described layer of non-magnetic material 2 and the screw rod 1.
The polygon cylinder that is shaped as hollow of described layer of non-magnetic material 2.
This screw rod is accomplished best fit to performance and cost, and very big practicality is arranged aspect high-leakage impedance transformer.
