Abstract
A method for preparing stator - core of automobile generator includes winding two narrow steel ribbons with T-shaped tooth at one side on each of them by winder in screw mode to let each tooth be coincided to another correspondingly after a high quality low carbon steel strip is suit - cut to be two said steel ribbons, then welding wound narrow steel ribbons to be cylindrical iron core with T shaped tooth at inner wall by applying argon arc welding.
Description
Technical field
The invention belongs to the iron core manufacturing process, especially relate to a kind of manufacturing technique method of automobile current generator stator core.
Background technology
At present, relevant iron core machining method is nothing but two kinds of processing methods.One is that punching silicon-steel is become the unit, and then every folded stator core or the rotor core made of punch forming.Yet above-mentioned processing method produces a large amount of tailings in the punching out process, the effective rate of utilization of silicon steel sheet is very low, has wasted a large amount of silicon steel sheet raw material.Its two, be that punching silicon-steel is become band, then banded silicon steel sheet is twined, helical coil coiled iron core, though above-mentioned processing method has been saved a large amount of silicon strips, technology difficulty is big, the processing cost and the cost of raw material are higher.
Summary of the invention
The objective of the invention is to overcome the weak point that exists in the above-mentioned technology, a kind of manufacturing technique method of automobile current generator stator core less waste material is provided.
For achieving the above object, the technical solution used in the present invention is:
High-quality mild-carbon steel strip material cover is cut into after two one sides are respectively the narrow steel bar of T font double wedge, on up-coiler, reels, make each tooth corresponding superimposed mutually with spiral way.The narrow steel bar of the low-carbon (LC) that coiling is finished is welded into the cylinder-shaped iron core that inwall is a T font double wedge with inferior arc-welding again.
The present invention is compared with the prior art the advantage that has: the present invention adopts high-quality low-carbon (LC) narrow steel strip (08) to process, and low processing cost has been saved lot of materials, and utilization rate of raw materials is 90%.
Description of drawings
Fig. 1 is the banded steel band punching out of a present invention schematic diagram.
Fig. 2 is the present invention's schematic diagram of reeling.
Embodiment
Below in conjunction with accompanying drawing enforcement of the present invention is described in further detail.By Fig. 1-Fig. 2 as can be known, process of the present invention is:
High-quality mild-carbon steel strip material cover is cut into after two one sides are respectively the narrow steel bar of T font double wedge, on up-coiler, reels, make each tooth corresponding superimposed mutually with spiral way.The narrow steel bar of the low-carbon (LC) that coiling is finished is welded into the cylinder-shaped iron core that inwall is a T font double wedge with inferior arc-welding again.Described mild-carbon steel strip material is No. 08 high-quality mild steel narrow steel strip, also can adopt the cold rolled silicon steel carrying material.
Figure of description 1 is that raw material adopt No. 08 high-quality low-carbon (LC) narrow steel strip, and its material adopts to be cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing marker method to cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing into two one sides of symmetric shape be the narrow steel bar of T font convex teeth portion 1.Carry out spiral way by principle shown in Figure 2 then and reel, the mutual correspondence of each tooth is carried out superimposedly then, adopts inferior arc-welding welding to manufacture the cylinder-shaped iron core that inwall is a T font double wedge 1 at last.
Obviously, this technology has not only been avoided the waste of leftover pieces and center circle material in the traditional handicraft, and pairing small quantity of material is also farthest utilized and gone up in the wire casing.
The present invention is applicable to the stator core manufacturing of middle and small motor.
