Abstract
The utility model relates to a three-step iron core side pillar positioning mold, and belongs to the technical field of tools special for a transformer. The technical scheme is that: the three-step iron core side pillar positioning mold comprises a positioning plate (1), a base plate (2), bolts or rivets (3); the positioning plate is mounted on the base plate; and the positioning plate is fixed with the base plate through the blots or rivets. The positioning plate is in a step structure; a recessed portion is arranged on the positioning plate, named as a female mold; a protuberant portion is arranged on the positioning plate, named as a male mold; and the female mold and the male mold are respectively used for stacking two side pillars of one iron core. The three-step iron core side pillar positioning mold has the advantages of small size, simpleness in positioning, and is convenient to use and the like; the iron core stacking quality and efficiency can be improved, so that the iron core joint is compact and correct; the levels of the stacked iron cores are clear; and the electromagnetic performance and mechanical performance of the iron core are guaranteed.
Description
Technical field
The utility model relates to a kind of three steppings side column positioning module unshakable in one's determination, belongs to transformer special tooling technical field.
Background technology
Transformer core is the heart of transformer, and its workmanship directly has influence on the performance and the reliability of operation of transformer.Iron core for a transformer requires chip level unshakable in one's determination inferior clear, and seam is correctly tight, and the edge of sheet does not have short circuit etc., guarantees electromagnetic performance unshakable in one's determination with this.Background technology: the seam of lamination is big, can cause no-load current and no-load loss big, causes mechanical strength unshakable in one's determination to weaken.For the iron core of yoke on the stack not, the stack of side column sheet does not have positioning tool, and the stack difficulty often produces quality problems such as stack deflection, seam difference.Above-mentioned situation can cause assembly process dowel difficulty, directly can cause no-load loss unshakable in one's determination high, quality problems such as overall mechanical strength reduction unshakable in one's determination.
The utility model content
The purpose of the utility model provides a kind of three steppings side column positioning module unshakable in one's determination; Can in the stack process of three seams side column sheet unshakable in one's determination, position the side column sheet; Improve the core lamination quality, make seam unshakable in one's determination tight, correct, stack back core level is inferior clear; Guarantee electromagnetic performance and mechanical property unshakable in one's determination, solve the problems referred to above that background technology exists.
The technical scheme of the utility model is: three steppings side column positioning module unshakable in one's determination, comprise location-plate, base plate, screw or rivet, and location-plate is arranged on the base plate, through screw or rivet location-plate and base plate is fixed together.
Location-plate is a step structure; Location-plate is provided with the depression position, is referred to as former; Location-plate is provided with the protruding part, is referred to as formpiston; Former and formpiston are respectively applied for two side columns of an iron core of stack.
The principle of the utility model is to utilize stepping amount and every lamination sheets thickness of lamination as the positioning tool design considerations; Design the width of stepped portion on the location-plate according to transformer core conventional design stepping gauge lattice, the thickness that goes out stepped portion on the location-plate according to two one folded method for laminating and lamination Thickness Design; During use base plate is inserted under the side column sheet that stack is good; Press next circulation lamination of stepped portion stack on the location-plate; Promptly by step sequence and the accurate stack of stepping amount, side column sheet stack is neat, seam is tight thereby make for side column sheet then unshakable in one's determination, improves the core lamination quality.According to two side column sheet stepping characteristics.
The good effect of the utility model: the utlity model has advantages of small volume, use advantages such as light, that the location is simple and direct; Core lamination quality and efficient have been improved; Make seam unshakable in one's determination tight, correct, stack back core level is inferior clear, guarantees electromagnetic performance and mechanical performance unshakable in one's determination.
Description of drawings
Fig. 1 is the utility model embodiment one sketch map;
Fig. 2 is the utility model embodiment two sketch mapes;
Among the figure: location-plate 1, base plate 2, screw or rivet 3, packing ring 4.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
Three steppings side column positioning module unshakable in one's determination comprises location-plate 1, base plate 2, screw or rivet 3 and packing ring 4, and location-plate is arranged on the base plate, through screw or Rivets & Washers location-plate and base plate is fixed together.Location-plate is a step structure.
Embodiment one, and with reference to accompanying drawing 1, location-plate is provided with the depression position, is referred to as former; Embodiment two, and with reference to accompanying drawing 2, location-plate is provided with the protruding part, is referred to as formpiston; Former and formpiston are respectively applied for two side columns of an iron core of stack.
Claims (2)
