Bending hole, make its be conducive to step 2. in carry out bending process.
In the method for the spliced stator core of manufacture above-mentioned, the step 1. in open slot in two sides be respectively equipped with
The corresponding recess portion of shape and protrusion, and step 2. after the completion of, open slot is closed as the bonding crack in stator yoke radially, and
To curving, indent or solder joint are located at the crooked position of bonding crack in the middle section of bonding crack.
In the method for the spliced stator core of manufacture above-mentioned, the lower end surface of the step 1. recess portion of split shed slot is lower than
The lower end surface of protrusion is being not necessarily to so that open slot, in closing, recess portion and protrusion generate extruding, and then improve bond strength
Also there is enough bond strengths when setting indent or solder joint.
In the method for the spliced stator core of manufacture above-mentioned, cell wall where the open slot upper convex portion and bending preformed hole
Junction be equipped with chamfering, in order to be bent to punching monomer.
Compared with prior art, the present invention is by crimping punching monomer lamination at cores pile in layers block, and by multiple laminations
Iron core block connects into complete stator core by joinery and its construction.And since the special construction of punching monomer of the invention is set
It sets, it can be bent by the punching monomer of vertical bar shaped and is combined into, and the punching monomer of vertical bar shaped can be in bullion piece
Upper carry out continuous punching, it is more convenient to process, and is conducive to automated production, and then improves production efficiency, reduces production cost.
It, can be since the stator teeth of the punching monomer of vertical bar type is complementary with slot form in addition, when the punching monomer of punching press vertical bar shaped
Bullion on piece stamps out two punching monomers being staggered simultaneously, at this time in the remaining material of bullion on piece with regard to phase
To many has been lacked, which greatly improves the stock utilizations of bullion piece, and then reduce material cost.Again due to the present invention
In open tank configuration on the punching monomer of vertical bar shaped setting so that the bonding crack on punching monomer has after bending
Higher bond strength, then welding or pressure is cooperated to set the mode of indent, it can be further improved bond strength, determine to ensure
The quality of sub- iron core.
