Abstract
The utility model discloses a feeding die for a rectangular module (RM)-shaped magnetic core. The RM-shaped magnetic core comprises a magnetic core center pillar and magnetic core side legs which are distributed on two sides of the magnetic core center pillar. The feeding die comprises a bottom plate (1) and two supporting frames (2), wherein the two supporting frames (2) are arranged on the bottom plate (1) in parallel and vertical way. Each supporting frame (2) consists of a plurality of supporting units (3); and each supporting unit (3) comprises a cambered surface (31) and planes (32), wherein the cambered surface (31) is positioned on the middle part, and the planes (32) are positioned on two sides of the cambered surface (31). The planes (32) of two adjacent supporting units are mutually connected; the supporting units (3) on the two supporting frames (2) are arranged oppositely; and the cambered surfaces (31) of supporting units (3) which are arranged oppositely are protruded outwards. The magnetic core center pillar is placed in a space formed by the cambered surfaces (31) of two supporting units (3), and the magnetic core side legs are limited by the planes (32). According to the utility model, magnetic cores remain stable in the feeding die during grinding; and the machining precision of the magnetic cores is improved.
Description
Technical field
The utility model relates to the magnetic core technical field of mold, relates in particular to a kind of feeding mould of the RM of being used for shape magnetic core.
Background technology
Day by day under the trend of light and thin type, miniaturization, increasingly high, more and more accurate at electronics and IT products to the processing request of some parts.Current, magnetic core is widely used in the electric equipment, in order to satisfy the performance requirement of magnetic core, the machining accuracy of magnetic core is had higher requirement.
In RM type magnetic core process, need grind RM type magnetic core, in grinding step; A plurality of RM type magnetic cores are placed in the grinding feeding mould, and are delivered on the grinding machine, under stable status, grind; Require promptly that a plurality of magnetic cores are in stable status in the feeding mould in process of lapping, can not take place axially and moving radially, thereby guarantee size that a plurality of magnetic cores are consistent, therefore; Mechanism design to the feeding mould of RM type magnetic core seems particularly crucial; So that a plurality of RM type magnetic cores are placed in the feeding mould, and a plurality of magnetic cores keep relative stability with respect to the feeding mould in the strenuous vibration of grinding machine, to guarantee the grinding precision of a plurality of magnetic cores.But the feeding mould that is used for magnetic core processing at present can not satisfy its precision processing request.Therefore, how to design a kind of feeding mould that improves magnetic core machining accuracy those skilled in the art assistant officer's technical problem to be solved.
The utility model content
To above defective, the utility model provides a kind of feeding mould of the RM of being used for shape magnetic core, magnetic core can keep stable state in the feeding mould in grinding step, has improved the machining accuracy of magnetic core.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of feeding mould that is used for RM shape magnetic core; Said RM type magnetic core comprises magnetic core center pillar and the magnetic core limit leg that is distributed in magnetic core center pillar both sides; Said feeding mould comprises base plate and two support frames, and two support frames laterally arrange and are vertically set on the base plate, and each support frame is made up of a plurality of support units; Each support unit comprises cambered surface that is positioned at the middle part and the plane composition that is positioned at the cambered surface both sides; The plane of adjacent two support units links to each other, and the support unit on two support frames is oppositely arranged, and the cambered surface of two support units that are oppositely arranged is outstanding laterally; The magnetic core center pillar is placed in the space that the cambered surface of two support units forms, and magnetic core limit leg is undertaken spacing by the plane.
Preferably, the vertical range between two support frames is adjustable.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model; Two support frames laterally arrange and are vertically set on the base plate; Each support frame is made up of a plurality of support units, and each support unit comprises cambered surface that is positioned at the middle part and the plane composition that is positioned at the cambered surface both sides, and the plane of adjacent two support units links to each other; Support unit on two support frames is oppositely arranged; And the cambered surface of two support units that are oppositely arranged is outstanding laterally, and the magnetic core center pillar is placed in the space that the cambered surface of two support units forms, and magnetic core limit leg is undertaken spacing by the plane.Like this; In the magnetic core grinding process; The magnetic core center pillar of magnetic core is placed in the space that the cambered surface of two support units forms, and magnetic core limit leg is undertaken spacing by the plane, and a plurality of magnetic cores can keep relative stability with respect to the feeding mould in the strenuous vibration of grinding machine; Guaranteeing the grinding precision of a plurality of magnetic cores, thereby improve the yield rate of magnetic core.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
A kind of structural representation that is used for the feeding mould of RM shape magnetic core that Fig. 1 proposes for the utility model.
The specific embodiment
As shown in Figure 1, be a kind of structural representation that is used for the feeding mould of RM shape magnetic core of the utility model proposition.
With reference to accompanying drawing; A kind of feeding mould that is used for RM shape magnetic core that the utility model proposes; Said RM type magnetic core comprises magnetic core center pillar and the magnetic core limit leg that is distributed in magnetic core center pillar both sides; Said feeding mould comprises that base plate 1 and 2, two support frames 2 of two support frames laterally arrange and are vertically set on the base plate 1, and two support frames 2 are arranged along the length direction of base plate 1.Each support frame 2 is made up of a plurality of support units 3; Each support unit 3 comprises cambered surface 31 that is positioned at the middle part and the plane that is positioned at cambered surface 31 both sides 32 compositions; The plane 32 of adjacent two support units 3 links to each other; Support unit 3 on two support frames 2 is oppositely arranged, and the cambered surface 31 of two support units 3 that are oppositely arranged is outstanding laterally, and the magnetic core center pillar is placed in the space that the cambered surface 31 of two support units 3 forms.
Like this; In the magnetic core grinding process; The magnetic core center pillar of magnetic core is placed in the space that the cambered surface of two support units forms, and magnetic core limit leg is undertaken spacing by the plane, and a plurality of magnetic cores can keep relative stability with respect to the feeding mould in the strenuous vibration of grinding machine; Guaranteeing the grinding precision of a plurality of magnetic cores, thereby improve the yield rate of magnetic core.
In order to satisfy the installation of different size RM type magnetic core, the vertical range between two support frames 2 is adjustable, to satisfy the application demand under the different application scene.
