Abstract
The invention relates to a structure of a welding power supply box body, comprising a box case (1) and lateral boards (2). The box case (1) and the lateral boards (2) are connected to the side edges of the box case (1) in a rotating mode; the box case (1) comprises an upper layer (11) for placing a weak current control layer, a middle layer (12) for placing a power module, a main transformer, a rectification layer and a strong current layer, and a lower layer (13) for placing a cooling water storage chamber; an air inlet (14) is arranged at the side of the middle layer (12); the middle layer (12) and the upper layer (11) respectively form an omniseal dustproof structure by two sealing bars (15) at both sides of the contact part among the middle layer (12), the upper layer (11) and the lateral boards (2). The invention has the advantages that IP23 requirements are met, and the damage to control circuits in welding equipment from bug dust and scrap iron in a workshop can be eliminated.
Description
Technical field
The present invention relates to a kind of casing, relate in particular to a kind of structure of welding power supply box body.
Background technology
Welding is by suitable means, make the metal object of two separation produce between atom (or molecule) in conjunction with and the method for attachment that fuses.The source of welding current is to be used for welding is provided electric current, voltage energy and has a kind of special equipment that is fit to the desired output characteristic of this welding method.
Along with the high development and the application of Control Technique of Microcomputer on the source of welding current of electronic technology, more and more higher to the requirement of source of welding current stability, reliability, anti-interference; Because the environment for use of the source of welding current is general all dust more workshop or open-air the use, and is higher to the protective action requirement of case shell.So reasonably design the case shell of the source of welding current, the total quality that improves the source of welding current played important effect.
According to the requirement of GB15579.1-2004 shell protection, the minimum degree of protection of the source of welding current of indoor use should be the IP21S of GB4208 regulation; The minimum degree of protection of the source of welding current of outdoor use should be IP23.2 expressions of IP21 and IP23: prevent that diameter from entering objects such as (prevent enter) fingers greater than the 12mm foreign matter.1 expression: prevent that dripping of vertical direction from causing adverse effect.3 expressions: prevent with vertical become 60 spend drench with rain and cause adverse effect.
State internal welding machine producer all adopts the minimum requirements of IP21S at present, and general device all will be because of protecting improper breaking down after using one or two years.And the National Standard GB15579.1-2004 source of welding current " in the requirement of shell protection, dust is not made stipulations to the influence that the source of welding current causes.Through applicant analysis for many years exactly the powder of the dust in workshop and band iron filings be fatal to the infringement of control circuit in the welding equipment.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of structure of welding power supply box body, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: case shell and side plate; Described case shell and side plate are rotationally connected at the side of case shell; In the case shell, comprise: be used to settle the upper strata of light current key-course, the lower floor that is used to settle the middle level of power model, main transformer, rectification and forceful electric power layer and is used to settle the cooling water storage chamber; Air inlet is by the side in middle level; Middle level and upper strata form hermetically sealed dustproof construction with two sealing strips respectively in the both sides with the side plate contact position.
Compared with prior art, the invention has the beneficial effects as follows: both satisfied the requirement of IP23, can get rid of the infringement of workshop dust, iron filings again control circuit in the welding equipment.

Fig. 2 is Fig. 1 latus inframedium four limit structure charts;
Fig. 3 is tank shell figure among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 1, Fig. 2, Fig. 3 as seen: the present invention includes: case shell 1 and side plate 2; Described case shell 1 and side plate 2 are rotationally connected at the side of case shell 1; In case shell 1, comprise: be used to settle the upper strata 11 of light current key-course, the lower floor 13 that is used to settle the middle level 12 of power model, main transformer, rectification and forceful electric power layer and is used to settle the cooling water storage chamber; Air inlet 14 is by the side in middle level 12; Middle level 12 and upper strata 11 form hermetically sealed dustproof construction with two sealing strips 15 respectively in the both sides with side plate 2 contact positions;
Described side plate 2 four limits are the structure of turning up (C, the D) interlock of inside volume structure (A, B) and case shell 1; Formed tight overlap joint.
Structure of the present invention is divided into 3 layers, the upper strata: pcb board, light current key-course; Middle level: power model, main transformer, rectification etc., the forceful electric power layer, rear section of this layer and upper strata form hermetically sealed dustproof construction with two sealing strips respectively in the both sides of casing, and the come in main transformer of cooling air in the middle of the movement, modules etc. of air inlet are passed through, with dust and control circuit shunting, stoped effect of dust, two-layer strong and weak electricity is separated installation in going up, and can prevent electromagnetic interference again; Lower floor: welding is a source of welding current cooling water storage chamber with the water tank chamber; Side plate (Fig. 2) four limits are inside volume structure diagram A, B, with case shell (Fig. 3) C, the D structure interlock of turning up, have formed tight overlap joint, can prevent that rainwater from entering from the slit of power supply box.
Claims (2)
