Description

Armature coil down-lead head width-limited flat mould

Technical field

The present invention relates to the motor production equipment, be specially armature coil down-lead head width-limited flat mould.

Background technology

Armature coil is the core component of motor, the armature coil lead riser is one of key position of whole armature coil, it is connected with commutator riser, play a part current lead-through, commutation, the lead riser of high-quality can reduce commutation spark, and the contact loss of minimizing and rise piece reduces the lead end temperature rise, reduce ageing of insulation, improve the service life of coil.

At present, it is flat that one of common process method of armature coil lead riser moulding is that lead riser rolls, it is even to roll flat back lead riser uneven distribution, shape is tapered, and the consequence of its existence is fully to contact with the commutator riser complete face, causes contact resistance to increase, the temperature rise of portion of coil lead end office (EO) is too high, ageing of insulation is accelerated, and the short probability of circle improves, and service life shortens greatly.On technology is made, lead riser roll flat after, also need increase the side cut operation and just can reach the drawing requirement, increased manufacturing cost to a great extent.

The another kind of process of armature coil lead riser moulding is to flatten.After flattening, the lead riser thin and thick is even, smooth smooth, when rule, can contact fully with commutator riser, makes the current of commutation unimpeded, and no local pyrexia phenomenon improves motor overall operation performance.But after flattening, because the copper cash extensional, width presents irregular state, and then size can't meet design requirement, and therefore needs to increase the side cut operation and guarantees width dimensions.Adopt " flattening+cuts edge " though technology can satisfy thickness, width dimensions requirement, technology is numerous and diverse, the mould input is bigger, and the production cycle is longer, and must accurately locate the end of a thread during side cut, has increased the difficulty of quality control.

Summary of the invention

When the present invention flattened moulding in order to solve the armature coil lead riser, the lead riser width can't once reach designing requirement, needed could guarantee by the side cut operation problem of lead riser width dimensions, and a kind of armature coil down-lead head width-limited flat mould is provided.

The present invention adopts following technical scheme to realize: armature coil down-lead head width-limited flat mould, comprise upper die and lower die, on the punching press end face of patrix, be provided with fin, cooperate with fin on the upper punch pressure side face and width equals the groove of armature coil lead riser design width having on the punching press end face of counterdie.Upper die and lower die are individually fixed on the punch press, the lead riser of armature coil are put into the groove of counterdie; Patrix is punching press downwards under the effect of punch press, and the fin on its punching press end face is pressed in the groove lead riser is implemented to flatten.Flatten finish after, the width of lead riser promptly is the width of groove, thereby time processing reaches designing requirement with regard to the width that makes lead riser.The fit form of fin and groove play the guiding role on the one hand in this shaping mould, and lead is stuck in down in the die cavity, when patrix when lifting, a side is empty in the counterdie unwrapping wire groove, and lead is taken out smoothly.

Adopt armature coil down-lead head width-limited flat mould of the present invention after flattening, need not to cut edge again, it is just reachability graph's paper designing requirement of one-shot forming, width tolerance is little (to be ± 0.1mm, and drawing requires ± 0.5mm),, improved product quality so greatly reduced manufacturing cost artificial, equipment, reduce manufacturing cost, shortened the production cycle greatly.Produce 100 motors with every month and calculate cost-saved 4500 yuan.It is even, smooth smooth to adopt this shaping mould to flatten back lead riser size thin and thick.Once can make the moulding successively of length both sides, reduce carrying, the shortening time.

Embodiment

Armature coil down-lead head width-limited flat mould, comprise patrix 1 and counterdie 2, on the punching press end face of patrix 1, be provided with fin 3, cooperate with fin 3 on the upper punch pressure side face and width equals the groove 4 of armature coil lead riser design width having on the punching press end face of counterdie 2.In order to realize being connected and fixed of upper die and lower die and punch press better, have screw at the top of patrix 1, the screw internal fixation has patrix die shank 5, by patrix die shank 5 patrix and punch press is fixed; Have screw in counterdie 2 bottoms, and be fixed with base plate 6 in the counterdie bottom, the two ends of base plate 6 have and are used for and the fixing groove of punch press, counterdie is placed on the punch press and by base plate and punch press fix.In order to further facilitate operation, improve crudy and enhance productivity, side at counterdie is provided with the armature coil detent mechanism, detent mechanism comprises positioning strip 7 that is fixed in base plate 6 one sides (base plate one side has screw) and the adjustable plate placed in the middle 8 that is fixed on the positioning strip 7 and relative positioning bar position is adjustable, adjustable plate 8 placed in the middle is made of level board and vertical panel and has a regulating tank 9 on level board, with bolt adjustable plate 8 placed in the middle is fixed on the positioning strip 7, when needing to regulate the position of adjustable plate placed in the middle, unclamp screw, adjustable plate placed in the middle can move in the regulating tank size range and realize its position adjustments.Armature coil is " U " shape and a length of side, short on one side, during work, the vertical panel that the long limit or the minor face of armature coil are close to adjustable plate placed in the middle, make the long limit of armature coil or minor face lead riser be arranged in counterdie groove middle part (promptly placed in the middle) by the position of regulating adjustable plate placed in the middle at groove, then with adjustable plate placed in the middle location, each follow-up like this armature coil is as long as be close to its long limit or minor face the vertical panel of adjustable plate placed in the middle, just can make lead riser placed in the middle in the counterdie groove, thus guarantee lead riser flatten back copper close be evenly distributed attractive in appearance.Described armature coil detent mechanism also comprises minor face backer locating piece 10 and long limit backer's locating piece 11, has chute 12 on positioning strip 7, with minor face backer locating piece 10 and long limit backer's locating piece 11 usefulness bolt in the chute 12 of positioning strip 7.Unclamp bolt, minor face backer locating piece 10 and long limit backer's locating piece 11 can slide in the chute of positioning strip 7, to adapt to the armature coil of different size.During work, by regulating the position of minor face backer locating piece 10 and long limit backer's locating piece 11, when making the afterbody of armature coil be close to minor face backer locating piece 10, the minor face end of armature coil just in time is positioned at the counterdie die; When making the afterbody of armature coil be close to long limit backer's locating piece 11, the end, long limit of armature coil just in time is positioned at the counterdie die, can further facilitate operation like this, improves crudy and improve working (machining) efficiency.
