Description
Technical field
The invention belongs to field of mechanical technique, relate to the manufacture craft of a kind of motor, particularly motor housing.
Background technology
Motor is widely used as a kind of power-equipment.Prior motor generally is made up of housing and the stator that is positioned at housing, rotor etc.Wherein the manufacturing of the housing of motor generally is to adopt urib founding.
Particularly, the raw material pig iron needs coke to refine through smelting furnace high temperature, and then makes casing blank by casting mould.Casing blank is made and is also needed to carry out deep processing by lathe behind the type and just can become the housing finished product.
Obviously, above-mentioned casting process is loaded down with trivial details, and Production Time is long, and the finished product rate is lower.Simultaneously owing to advance rising steadily of several years metal prices of raw and semifnished materials, make the cost of manufacture of above-mentioned technical process than higher, and coke is an other expense again.Therefore, the manufacturing process of above-mentioned electric machine casing is the cost height not only, but also wastes energy.
" a kind of generator " that Chinese patent (publication number CN2779712Y) provides, this generator is to set up demodulator in common electric machine casing.The housing that is to say this motor remains and forms by urib founding.This patent still exists the existing defective of common electric machine housing.
Summary of the invention
The objective of the invention is at existing in prior technology the problems referred to above, a kind of manufacture craft that makes the motor housing that electric machine casing is simple for production, easy to implement is provided.
Purpose of the present invention can realize by following technical proposal: a kind of manufacture craft of motor housing, and this technology may further comprise the steps:
A, making inner core: selecting sheet metal for use, sheet metal is cut to the rectangle sheet material of setting size, is cylindric with rectangle sheet material volume then; Two edges of rectangle sheet material behind the volume are connected to make together is inner core blank cylindraceous, and the last base that is connected in the outside of inner core blank obtains inner core;
B, making fin: adopt general metal casting technique to make the fin blank that is sheet shape strip, and have some radiating fins that are connected as a single entity with it in the fin blank outside, then above-mentioned fin blank is cut according to preseting length, obtain fin;
C, making end cap: adopt general metal casting or Sheet Metal Forming Technology to make the end cap of metal material;
D, part connect: fin is connected on the inner core, two end caps is connected in the two ends of inner core respectively.
When making the housing of motor, at first adopt the metal cutter to cut out the rectangle sheet material of setting size.Then the rectangle sheet material that cuts is curled, and it is fixed together welding of sheet material two edges or securing member, make above-mentioned rectangle sheet material be processed to inner core blank cylindraceous.By welding or the securing member base that is used to support that is connected in the inner core blank outside, just make the inner core manufacturing of electric machine casing be shaped.
Then make fin.Fin adopts general metal casting technique to make, and obtains being the fin blank of the strip of sheet shape after the casting.Certainly, the radiating fin that is used to dispel the heat that on fin, has some protrusions.Because the length of fin blank is long.Adopt Metal Cutting equipment fin to be cut, obtain fin according to the length of setting.
Certainly, in two above-mentioned steps, fin can be made earlier, also inner core can be made earlier.The making that is to say steps A and step B does not have sequencing.
In addition, end cap adopts general metal casting or metal stamping technology to make.Same, step C does not have the making sequencing with respect to steps A and step B yet.
At last the end cap made is connected in the two ends of motor inner core by securing member, fin is connected in the inner core outside, make fin wrap in inboard outer.Whole electric machine casing is just made moulding.
In the manufacture craft of above-mentioned motor housing, described sheet material is cold rolled plate, and the thickness of sheet material is 0.4-2mm.Because rectangle sheet material forms by cutting, adopt cold rolled plate to make that it can be by cutting easily.Meanwhile, adopt the cold rolled plate material to make rectangle sheet material have good cold-bending property, simultaneously, its welding performance is also relatively good in welding process.
In the manufacture craft of above-mentioned motor housing, the rectangle sheet material after cooperating diel with cutting by punch press in the described steps A carries out punching press, and four burr of rectangle sheet material are removed.Owing to directly make the four edges edge of rectangle sheet material be coarse burr by cutter cutting sheet material.Just burr can be dispeled by punching press, make the four edges of the rectangle sheet material after the punching press simultaneously along smooth.
In the manufacture craft of above-mentioned motor housing, rectangle sheet material curls by rotary machine in the described steps A.Adopt rotary machine conveniently rectangle sheet material to be curled for cylindric.
As another scheme, in the manufacture craft of above-mentioned motor housing, rectangle sheet material curls by punch press in the described steps A.Certainly, cooperating diel, being processed to that rectangle sheet material also can be fast and convenient on punch press is cylindric.
In the manufacture craft of above-mentioned motor housing, rectangle sheet material extrudes connecting hole one by mould in rectangle sheet material upper punch in the described steps A in punching course.Because fin will be connected in the inner core outside, therefore, process connecting hole one after, fin just can directly be connected on the inner core by securing member.
In the manufacture craft of above-mentioned motor housing, base once is stamped to form cold rolled plate by punch press in the described steps A.Base is just played a supporting role, and therefore, is cooperating the diel just can be with the moulding of base time processing on punch press.Certainly, according to actual conditions, the also base that can adopt urib founding to form.
In the manufacture craft of above-mentioned motor housing, fin is made by aluminum alloy materials among the described step B.The code name of this Birmasil is encoded to 200, the fin intensity height that the employing aluminum alloy materials is made, in light weight.
In the manufacture craft of above-mentioned motor housing, on fin, process some connecting holes two by drill bit among the described step B, and connecting hole two is corresponding with the position of connecting hole one.Securing member pass connecting hole once and connecting hole two fin can be fixed on firmly the inner core outside.
In the manufacture craft of above-mentioned motor housing, the quantity of fin is the 2-4 sheet among the described step D, and they are distributed on the inner core outside.Fin adopts a plurality of heat radiating fin structures of having simplified, and it is easier also to seem in the part connection procedure.
Compared with prior art, the manufacture craft of this motor housing is owing to be divided into end cap, inner core and three parts of fin with housing.And inner core is made by cold rolled plate, and fin is made by aluminum alloy materials, has reduced the material consumption of housing so greatly, makes the cost of whole electric machine casing compare the end, has the higher utility of ratio.
Simultaneously, fin and inner core all can be produced in enormous quantities, and the part scrappage is much lower for urib founding in manufacturing process.Therefore, this technology not only makes electric machine casing processing easier, and part can produce in enormous quantities, can increase substantially the finished product rate.
