The female-die twisting mechanism is simple in structure, so that a stamping sheet can rotate for a degree during blanking, automatic twisting folding and riveting can be achieved, the work efficiency is improved, and the female-die twisting mechanism is very practical.
Description
Technical field
The utility model relates to a kind of mold component, relates in particular to a kind of die twist mechanism.
Background technology
In motor, electric equipment products, silicon steel sheet closed assembly iron core is one of important parts, and iron core weight accounts for the 25%-30% of product weight, and quality unshakable in one's determination has direct impact to properties of product.Iron core is generally to be made by the silicon steel sheet of the high and low loss of permeability, for reducing loss, requires iron core to be divided into vertically thin slice, and thickness is at 0.35mm or 0.5mm, and therefore an iron core can be comprised of tens as many as hundreds of sheet silicon steel sheets.Therefore the manufacturing batch of iron-core lamination is very large.The processing method operation unshakable in one's determination of using in the past is many, and manual operations is many, and production efficiency is low, and labor strength is large, the closed assembly difficult quality guarantee.Along with the development of industrial technology, adopted the progressive die production on high velocity ram machine, tend to high-speed automated production.Closed assembly unshakable in one's determination is progressively by the automatic overlapping and assembling transition of traditional processing method to iron core.Automatic overlapping installation mould feeding technology unshakable in one's determination has begun to apply in industrial advanced country in 20 century 70 later stages.In the motor that the automatic overlapping and assembling technology is applicable to produce in enormous quantities, electric equipment products, applicable stamping-out speed can reach 140-350 time/min, and a sharpening life-span reaches more than 1,000,000 times, and mould entire life can be up to more than a TFlops.The automatic overlapping and assembling technology can be used for motor stator and rotor and mountain shaped iron core etc., superimposed Li Keda 75N-120N.Punching motor stator, rotor core on progressive die, sometimes the mode that needs to take to reverse is folded riveting, i.e. upper each punching unshakable in one's determination will be rotated a low-angle folded riveting again, requiring has a little windup-degree between every two of rotor punching, and existing progressive die does not have twist mechanism, can not realize automatically reversing folded riveting, very inconvenient.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of die twist mechanism, and is simple in structure, can make punching rotate an angle in blanking, realizes automatically reversing folded riveting, improved operating efficiency, very practical.
The technical solution of the utility model is: a kind of die twist mechanism, comprise die shoe, the die shoe upper surface has groove, rotor die holder is connected in groove by sprocket rotation, have up big and down small ladder hole on rotor die holder, the rotor blanking die is socketed on ladder hole inwall upper end, and the rotor blanking die adopts carbide alloy to make, bottom portion of groove has the material-dropping hole that is communicated with ladder hole, is provided with the head part rubber blanket in material-dropping hole.
As preferably, be respectively arranged with upper and lower centring ring between rotor die holder upper/lower terminal sidewall and recess sidewall, be respectively arranged with needle bearing between upper and lower centring ring sidewall and rotor die holder sidewall, be provided with the plane needle bearing between upper centring ring bottom surface and rotor die holder.
As preferably, die shoe and rotor die holder all adopt the Q235 steel to make, and are provided with backing plate between rotor die holder lower surface and bottom portion of groove, and the die shoe lower surface is provided with lower bolster, has the through hole that is communicated with material-dropping hole on lower bolster.
The beneficial effects of the utility model are: rotor blanking die of the present utility model is arranged in rotor die holder, rotor die holder is connected in the groove of die shoe by sprocket rotation, sprocket wheel can rotate an angle around the axle center under the drive of rotating shaft, thereby make punching rotate an angle in blanking, form rotor core and reverse the operation of groove, realize automatically reversing folded riveting, improved operating efficiency.Needle bearing and plane needle bearing have guaranteed running accuracy, have avoided rotor blanking punch and rotor blanking die to gnaw the sword phenomenon, and be very convenient and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of die twist mechanism comprises die shoe 1, and die shoe 1 upper surface has groove, rotor die holder 9 is rotationally connected with in groove by sprocket wheel 5, have up big and down small ladder hole on rotor die holder 9, rotor blanking die 7 is socketed on ladder hole inwall upper end, and rotor blanking die 7 adopts carbide alloy to make, bottom portion of groove has the material-dropping hole that is communicated with ladder hole, facilitates punching to fall from die shoe 1.Be provided with head part rubber blanket 2 in material-dropping hole.
In the present embodiment, as preferably, be respectively arranged with upper and lower centring ring 6,10 between rotor die holder 9 upper/lower terminal sidewalls and recess sidewall, be respectively arranged with needle bearing 4 between upper and lower centring ring 6,10 sidewalls and rotor die holder 9 sidewalls, be provided with plane needle bearing 8 between upper centring ring 6 bottom surfaces and rotor die holder 9.Needle bearing 4 and plane needle bearing 8 can guarantee running accuracy for the rotation guiding of rotor die holder 9, have avoided rotor blanking punch and rotor blanking die 7 to gnaw the sword phenomenon.
In the present embodiment, as preferably, die shoe 1 and rotor die holder 9 all adopt the Q235 steel to make, and are provided with backing plate 3 between rotor die holder 9 lower surfaces and bottom portion of groove, die shoe 1 lower surface is provided with lower bolster 11, has the through hole that is communicated with material-dropping hole on lower bolster 11.
