Abstract
The utility model discloses a motor core welding frock mould lower mould, including rigid coupling terrace die cushion and terrace die together, the cover is equipped with ejecting cover outside terrace die cushion, and it has the welding lower cover to support at ejecting cover, and its special character is: the outer surface of the male die is evenly provided with clamping grooves with the number equal to that of the motor core grooves along the circumferential direction, the clamping grooves are respectively clamped with embedded cores, the embedded cores protrude out of the outer surface of the male die, and the upper end of the male die is fixedly connected with an upper gland. The advantages are that: 1. because the male die and the insert core are of a split structure, the male die can be machined by using a cylindrical grinder, the machining precision of the die is high, and the final product quality can be improved; 2. after a certain insert on the male die is damaged, a single insert is directly replaced, the service life of the male die is long, and the maintenance cost of the die is low.
Description
Technical field
The utility model is particularly related to a kind of electric machine iron core welding tooling lower mould.
Background technology
Prior motor iron core welding tooling lower mould is by the punch cushion block and the punch that are fixed together, is enclosed within the ejector sleeve of punch cushion block outside and is sitting on the ejector sleeve and the welding that is enclosed within the punch outside formation of trapping.Punch wherein is cylindrical, on its external cylindrical surface, is evenly equipped with the card tooth of one.The problem that this counterdie exists is: 1, because punch is an one with the card tooth, and therefore needing to adopt electric machining is that the line cutting processing forms, and need hand lapping to accomplish, so machining accuracy is not high, can directly influence operating efficiency and product quality; 2, directly cause whole punch to be scrapped after any card tooth on the punch damages, so punch is short service life, the mould maintenance cost is high.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of machining accuracy high, long service life, the electric machine iron core welding tooling lower mould with product quality of can increasing work efficiency.
The electric machine iron core welding tooling lower mould that the utility model relates to comprises punch cushion block and the punch that is fixed together; Be arranged with ejector sleeve in punch cushion block outside; On ejector sleeve, be supported with welding and trap, its special character is: along the circumferential direction be evenly equipped with the draw-in groove that equates with electric machine iron core groove quantity at the punch outer surface, in draw-in groove, snapped in the edge core respectively; The edge core protrudes from the outer surface of punch, is connected with upper press cover in the punch upper end.
Above-mentioned electric machine iron core welding tooling lower mould, described punch cylindrical top is taper, so that iron core is installed, enhances productivity.
Above-mentioned electric machine iron core welding tooling lower mould, described edge core are to be made up of with location edge core the guiding edge core that is distributed in the punch outer rim draw-in groove, so that iron core is installed, enhance productivity.
The utility model has the advantages that: 1, since punch and edge core for dividing body structure, so punch can use cylindrical grinder processing, the Mould Machining precision is high, can improve final product quality; 2, directly change single edge core after the edge of certain on punch core damages and get final product, the punch long service life, the mould maintenance cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: ejector sleeve 1, iron core 2, punch 3, draw-in groove 301, upper press cover 4, edge core 5, welding traps 6, punch cushion block 7, moved cross beam 8.
The specific embodiment
As shown in the figure; The related electric machine iron core welding tooling lower mould of the utility model comprises the punch cushion block 7 and punch 3 that is fixed together through bolt; Be arranged with ejector sleeve 1 in punch cushion block 7 outsides, on ejector sleeve 1, be supported with welding and trap 6, welding trap 6 be enclosed within punch 3 the outside; Along the circumferential direction be evenly equipped with the draw-in groove 301 that equates with electric machine iron core groove quantity at punch 3 outer surfaces; In draw-in groove 301, snapped in edge core 5 respectively, edge core 5 protrudes from outer surface and the projection and the electric machine iron core groove matched in clearance of punch 3, is connected with upper press cover 4 in punch 3 upper ends through bolt; Upper press cover 4 is pressed in the upper end of edge core 5, and edge core 5 is spacing through upper press cover 4 and punch cushion block 7.Described edge core 5 is to be made up of with location edge core 502 the guiding edge core 501 that is distributed in the punch 3 outer rim draw-in grooves 301; Present embodiment guiding edge core is an example with 6; All the other are 30 location edge cores 502, and the cross section outer end of guiding edge core 501 is a round end, installs when twining iron core and can play guide effect.Described punch 3 cylindrical tops are that taper and upper end external diameter are less, so that iron core is installed, enhance productivity.
During installation; Be fixed on punch cushion block 7, punch 3 and upper press cover 4 on the moved cross beam 8 of automatic welder(welding machine) through stay bolt; Ejector sleeve 1 is fallen on the moved cross beam 8; Be set to the upper end of the iron core 2 after twining from punch 3 on the punch 3 when iron core 2 is twined in welding, less because of the external diameter of punch 3 upper ends, iron core 2 is directly fallen the intermediate location up and down of punch 3 by deadweight; At this moment start the welding machine automatic button, up through moved cross beam 8 makes punch 3 get into the patrix of electric machine iron core welding tooling moulds, and iron core 2 is pressed into the bottom of punch 3 and falls welding and trap and realize accurately location on 6, and welding machine welds automatically simultaneously.
Claims (3)
1. electric machine iron core welding tooling lower mould; Comprise the punch cushion block and the punch that are fixed together, be arranged with ejector sleeve, on ejector sleeve, be supported with welding and trap in punch cushion block outside; It is characterized in that: along the circumferential direction be evenly equipped with the draw-in groove that equates with electric machine iron core groove quantity at the punch outer surface; In draw-in groove, snapped in the edge core respectively, the edge core protrudes from the outer surface of punch, is connected with upper press cover in the punch upper end.
2. electric machine iron core welding tooling lower mould according to claim 1 is characterized in that: described punch cylindrical top is taper.
