Abstract
The utility model discloses an obround winding die, which comprises two baffle plates (1) with the edges being provided with an outgoing-line groove (4) and the center being provided with a square hole (3) that is used for the square shaft of a winding machine to pass through; the obround die also comprises two arch plates (2) with the cross section being of a semi-circular shape and two axial ends being provided with an end plate; the two baffle plates (1) are provided with two semi-circular through holes that are used for accommodating the arch plates (2); the two ends of the two arch plates (2) are arranged inside the semi-circular trough hole corresponding to the two baffle plates (1) in a sliding way; the junction part between the two axial ends of the two arch plates (2) and the two baffle plates (1) is provided with a device that is used for preventing the two baffle plates (1) and the two arch plates (2) from moving inward in the axial direction. The obround winding die has convenient mold stripping and low production cost.
Description
Technical field
The utility model relates to a kind of Long Circle coiling mould, specifically is a kind of Long Circle coiling mould that is used for coiling transformer low voltage wound coil.
Background technology
The Long Circle coiling mould of prior art is that oblong cylinder and two baffle plates are formed by cross section, and this cylinder is formed by stacking by two core rods that are the inclined-plane.There is following defective in the Long Circle mould of above structure: because the cylinder of Long Circle mould is to be superimposed as by two core rods that are the inclined-plane, and the stiction of core surface is bigger, coil winding is finished, after removing two baffle plates, need just can make mould throw off its knockout course difficulty to the power that mould applies perpendicular to the cylinder cross section; Simultaneously, because this Long Circle mould is solid cylinder,, make its cost of manufacture higher relatively so it is more to make this Long Circle mould consumptive material.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of and is convenient in demoulding and Long Circle coiling mould that manufacturing cost is low relatively.
Technical solution of the present utility model is, a kind of Long Circle coiling mould with following structure is provided, it comprises that two block edges are equipped with out wire casing, central authorities are equipped with the baffle plate of the square hole that passes through for the coil winding machine square shaft, described Long Circle mould comprises that also two cross sections have the arch sheet of end plate for semicircle and axial two ends, be equipped with two semi-circular through hole of ccontaining arch sheet on described two baffle plates, the two ends sliding fit of described two arch sheets is in two corresponding semi-circular through hole of baffle plate, and the axial two ends of described two arch sheets and the junction of two baffle plates are provided with the device that limits between two baffle plates and two arch sheets to axial to intrinsic displacement.
During the coiling of this Long Circle mould, the coil winding machine square shaft is passed baffle plate central authorities square hole, line is after the going out wire casing and enter an of end-stopping plate, and the coiling arbor drives mould and begins rotation, makes line be wrapped on two arch sheets.After coiling was finished, line passed from the wire casing that goes out of the other end.
After adopting above structure, the utility model Long Circle mould compared with prior art has the following advantages:
Because this Long Circle mould is a composite type, the two ends sliding fit of described two arch sheets is in two corresponding semi-circular through hole of baffle plate.So after coiling is finished,, two arch sheets and the coil that winds are thrown off, make knockout course very simple and convenient as long as remove two baffle plates.Simultaneously, because this Long Circle mould has replaced original solid cylinder with two arch sheets,, reduced the manufacturing cost of this Long Circle mould so saved lot of materials.
Description of drawings
Accompanying drawing is the structural representation of the utility model Long Circle coiling mould.
Shown in the figure 1, baffle plate, 2, arch sheet, 3, square hole, 4, go out wire casing, 5, technology groove.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure.
The utility model Long Circle is an oval shape coiling mould, and it comprises that two block edges are equipped with out the baffle plate 1 that wire casing 4, central authorities are equipped with the square hole 3 that passes through for the coil winding machine square shaft.The edge of described two baffle plates 1 also is provided with a plurality of technology grooves 5 except that being provided with out wire casing 4.Described Long Circle mould comprises that also two cross sections are the arch sheet 2 that there is end plate at semicircle and axial two ends, are equipped with two semi-circular through hole of ccontaining arch sheet 2 on described two baffle plates 1.The two ends sliding fit of described two arch sheets 2 is in two baffle plates, 1 corresponding semi-circular through hole, and the axial two ends of described two arch sheets 2 and the junction of two baffle plates 1 are provided with the device that limits between two baffle plates 1 and two arch sheets 2 to axial to intrinsic displacement.Between two baffle plates 1 of described qualification and two arch sheets 2 to axial the device to intrinsic displacement refer to, the cross section at the two ends of two arch sheets 2 all less than the cross section of arch sheet 2 mid portions to form limited step, the two ends sliding fit of described two arch sheets 2 refers to the relatively little two ends sliding fit of this cross section in two baffle plates, 1 corresponding semi-circular through hole in two baffle plates, 1 corresponding semi-circular through hole, the axial two ends of two baffle plates 1 and two arch sheets 2 and adhesion be that screw thread by coil winding machine square shaft two ends compresses and reaches.
Claims (2)
1, a kind of Long Circle coiling mould, it comprises that two block edges are equipped with out wire casing (4), central authorities are equipped with the baffle plate (1) of the square hole (3) that passes through for the coil winding machine square shaft, it is characterized in that: described Long Circle mould comprises that also two cross sections have the arch sheet (2) of end plate for semicircle and axial two ends, be equipped with two semi-circular through hole of ccontaining arch sheet (2) on described two baffle plates (1), the two ends sliding fit of described two arch sheets (2) is in the corresponding semi-circular through hole of two baffle plates (1), and the junction of the axial two ends of described two arch sheets (2) and two baffle plates (1) is provided with the device that limits between two baffle plates (1) and two arch sheets (2) to axial to intrinsic displacement.
2, Long Circle coiling mould according to claim 1, it is characterized in that: between two baffle plates of described qualification (1) and two arch sheets (2) to axial the device to intrinsic displacement refer to, the cross section at the two ends of two arch sheets (2) all less than the cross section of arch sheet (2) mid portion to form limited step, the two ends sliding fit of described two arch sheets (2) refers to that in the corresponding semi-circular through hole of two baffle plates (1) the relatively little two ends sliding fit of this cross section is in the corresponding semi-circular through hole of two baffle plates (1).
