In the utility model, in order to simplify the structure of punching press punch and drift, further preferred embodiment is that 2 are provided with 3 button riveting points on said strip silicon steel sheet.
In the utility model, for make between the some silicon steel sheets button riveting firm and attractive in appearance, further preferred embodiment is, the last a slice in the said pen type silicon steel sheet that connects into through button riveting structure is provided with through hole 7 at position of its button riveting point 6.
Extremely shown in Figure 6 like Fig. 4; Another embodiment of the utility model is the button riveting device of a kind of pen-type ignition coil iron core of design; This button riveting device comprises the blanking punch 8 and blanking die 9 that cooperatively interacts and be used for blanking and detain riveting; In said blanking punch 8, be provided with blanking push rod 10, be provided with button riveting drift 11 in the end of said blanking push rod 10, said button riveting drift 11 protrudes from the lower surface of blanking punch 8; Said blanking die 9 is arranged in the die version 12, is provided with tightening ring 13 in the lower end of said blanking die 9 and die version 12; Between said blanking punch 8 and blanking die 9, be provided with silicon strip to be punched 14, be used to hold the silicon steel sheet 2 behind the blanking in described blanking die 9 and the tightening ring 13.
In the utility model, the installation site of said blanking push rod 10 in blanking punch 8 is corresponding with the position and the quantity of said button riveting point 6 with quantity.
In the utility model, the peripheral size of said tightening ring 13 inside is less than the peripheral size 0.01～0.015mm of blanking die 9 inside.
In the utility model, described blanking punch 8 is respectively equipped with some groups with blanking die 9, is respectively applied for the silicon steel sheet 2 of punching press, button riveting different in width.
Be arranged with the silicon steel sheet 2 of 5 different in width at the Width of said silicon strip 14.
This pen-type ignition coil iron core is to adopt high speed and precision punch press and automatic laminating high speed progressive die to accomplish the automatic press and the riveted of iron core, and concrete iron core manufacturing process is:
The silicon strip raw material are chosen → receiving inspection → silicon steel sheet punching press → silicon steel sheet pressing → examination and test of products → warehouse-in → payment
Adopt the advantage of technique scheme to be: 1, whole manufacturing process is simple, only punching press one procedure of critical process, and for improving the stacking factor of iron core, back road has increased the pressing operation.2, manufacture process needs artificial lacking, and mainly leans on equipment and mould to accomplish constant product quality.3, automatic press production efficiency is high, relative prior welding mode, and production capacity improves 3～5 times, and reduction iron core manufacturing cost, shortening product are had very important significance delivery cycle.
The key of the utility model is the design and the manufacturing of automatic laminating high speed progressive die: 1, in punching course, realize the bales catch riveting through mould; 2, mould adopts multiple row stock layout mode, once goes out a plurality of measure-alike iron cores, enhances productivity and stock utilization; 3, be provided with a hitch riveting control system with the supporting need of mould and realize that to regulate the different in width punching is by the product requirement Automatic Combined.
The utility model is provided with in the automatic laminating mould buckles riveting drift 11; Said button riveting drift 11 is gone out button riveting point 6 on silicon strip 14; The button riveting point of going out 6 when arriving the blanking position, is thrust and falls into blanking die 9 (as shown in Figure 4) by blanking punch 8 along with silicon strip moves forward.
The silicon steel sheet 2 that falls into blanking die 9 receives the stamping press effect of past lower direction this moment; Receive simultaneously the effect of below tightening ring 13 tightening force up again; Because of the size little 0.01-0.015mm of tightening ring 13 sizes than blanking die 9; So silicon steel sheet suffered tightening force in tightening ring 13 is also bigger; Under the effect of the power of these two kinds of different directions, the blanking push rod 10 of outstanding blanking punch 8 holds out against the button riveting point 6 of silicon steel downwards in addition, silicon steel sheet 2 that falls and following silicon steel sheet snapping together tightly.For guaranteeing the riveted power of silicon steel sheet, be designed with 3 button riveting points 6 that are uniformly distributed with on the silicon steel sheet 2, about 3 button riveting points 6 receive simultaneously, after the effect of two different directions power, will detain the riveting silicon steel sheet and closely fasten.
In the utility model, the automatic laminating mould is equipped with the lamination control device, and when reaching the regulation sheet and count, the through hole sheet is gone out in the cylinder action, with the iron core of riveted moulding separately, forms a complete button riveting iron core, shown in accompanying drawing 1.
Welding iron core of the prior art; Earlier go out the different iron core monolithic of various width with how secondary simple die; Press iron core combination needs then, with the iron core monolithic of tens kinds of different in width separately, and carry out manual work according to the sequencing of different in width monolithic and manage sheet; To manage good lamination again and put into special tooling, carry out laser welding.Whole process relies on Artificial Control fully, consumes the many and easy error of manpower, and production efficiency is low, and iron core quality stability is relatively poor.
Fig. 1 is the utility model bales catch riveting pen type iron core, is to control through precision stamping equipment and automatic laminating mould, and iron core quality stability is good, and production efficiency is high.3 button rivetings that are uniformly distributed with iron core of naming a person for a particular job closely snaps together, and the iron core stacking factor is high, better performances.
The bales catch riveting pen type iron core that adopts the utility model to make, technology is simple, and is easy to operate, accomplishes processing through precision equipment and mould, and it is few to consume manpower; Bales catch riveting progressive die adopts multiple row stock layout mode, and stock utilization is high, speed of production is fast, falls this, raises the efficiency bigger practical value for industry energy conservation.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
