Abstract
The invention relates to a method for preparing a coiling type generator stator core. The method comprises the following steps: (1) uncoiling and leveling a coiled steel belt; (2) pressing: utilizing a pressing machine to divide the steel belt into two disconnected linear continuous jugged strip materials with same size after three-step pressing with a progressive type pressing die; (3) winding: directly connecting the two linear continuous jugged strip materials to a feeding device of a winding machine through a guiding frame and a blanking slot, winding into two round helical incompact iron cores with a preset number of turns on the winding machine, and then separating from the jugged strip materials by utilizing a cutting device; (4) welding the formed incompact iron cores into an integrated stator core with orderly corresponded teeth and a size in a preset range; (5) reshaping: pressing and reshaping the welded stator core in a reshaping die; and (6) finishing. The method of the invention has the advantages of high material use ratio, high product quality, simple manufacturing and lower production cost.
Description
Technical field:
The present invention relates to a kind of manufacture craft of takeup type electricity generator stator core.
Background technology:
Referring to Fig. 1, the method that traditional handicraft is made electricity generator stator core is that silicon steel sheet is struck out individual circular chip, again through artificial lamination, press-fit, operation such as welding makes.The shortcoming of this method is: 1, stock utilization is extremely low, and its corner and middle part circle is all washed out during punching, causes very big waste; The slit appears between sheet and the sheet when 2, press-fiting easily, and because unrelated between sheet and the sheet, thus more or less exist difference material itself or artificial between every on the material, thus influence the performance of generator; 3, processing technology complexity, efficiency is not high.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, the manufacture craft of a kind of stock utilization height, good product quality, making is simple, processing cost is low takeup type electricity generator stator core is provided.
In order to realize the foregoing invention purpose, the present invention has adopted following technical scheme:
A kind of manufacture craft of takeup type electricity generator stator core is characterized in that comprising the steps:
(1) uncoiling, smoothing: discoid steel band is placed on the uncoiler, adjusts the smoothing speed of levelling machine and make it coupling, drive the uncoiler running, steel band is opened successively from cylindrical by levelling machine according to the step pitch of punch press speed and punch die;
(2) punching press: adopt forcing press to carry out punching press, by the step-feeding diel steel band is divided into two after through three step punching presses and does not link mutually and size is in full accord and two continuous profile of tooth billots of type linearly;
(3) reel: two linear pattern profile of tooth billots after the punching press directly are connected with the pay-off of up-coiler with stagnant hopper through the guide frame, and on up-coiler, be wound into two circles and be the spiral helicine loose iron core of pre-fixing turn, separate from the profile of tooth billot by shear again, during shearing, also by positioner make moulding loose iron core initiating terminal be in same linear position by end;
(4) welding: the loose iron core after the moulding is installed on the jig, loose iron core is welded into corresponding neat, the unitary stator iron core of size in prescribed limit of each tooth by welding machine;
(5) shaping: the stator core after will welding is put in the shaping mould, by the hydraulic press pressurization, makes it produce certain plastic deformation, thereby meets the requirements of size, and the pressure of shaping is 180～250 tons, and ejecting force is 12～18 tons;
(6) finishing: with the burr removing at each position of stator core after the shaping.
Three step punching presses during described punching press comprise: the first step is at steel band end punching press R arc, second step is stomidium under steel band middle part punching press U-shaped upper end hole and U-shaped, described U-shaped upper end hole and hole site, U-shaped lower end interlace and are row respectively and distribute, the 3rd phase fault punching press side opening of step between upper end hole and following stomidium;
Three step punching presses during described punching press comprise: the first step is at steel band end punching press R arc, second step is at steel band middle part punching press interstitial hole, the 3rd step stomidium under the upper and lower both sides punching press of interstitial hole U-shaped upper end hole and U-shaped, described U-shaped upper end hole and hole site, U-shaped lower end interlace and are row respectively and distribute.
The present invention has following advantage with respect to prior art after adopting technique scheme:
The first, because the raw material of initial manufacture are billot and are the profile of tooth arrangement that intermeshes, thereby do not exist raw-material a large amount of waste problem, stock utilization can improve more than 70%.
Second, because each stator core all is that same steel band continuous reeling forms, and powerful shaping through forcing press, thereby can avoid occurring difference material itself or artificial between sheet and the sheet and avoiding occurring the slit, make it all be better than traditional punching formula iron core at dimensional accuracy, surface treatment and aspect of performance.
The 3rd, because two linear pattern profile of tooth billots after the punching press directly are connected with the up-coiler pay-off with deflector chute through the guide frame, have achieved the automatic feed of profile of tooth billot, thereby can increase work efficiency, reduce labour intensity.
The 4th, be in same linear position owing to the initiating terminal of the loose iron core that makes moulding by positioner and by end, thereby can guarantee the evenness of stator core upper and lower end face after shaping.

Fig. 2 is the manufacture craft schematic flow sheet of generator stator core of the present invention;
Fig. 3 is a winding process schematic diagram of the present invention.
Embodiment:
Referring to Fig. 2 and Fig. 3,, it is characterized in that comprising the steps: according to the manufacture craft of takeup type electricity generator stator core provided by the invention
(1) uncoiling, smoothing: the discoid steel band of 1 millimeters thick is placed on the uncoiler, adjusts the smoothing speed of levelling machine and make it coupling, drive the uncoiler running, steel band is opened successively from cylindrical by levelling machine according to the step pitch of punch press speed and punch die;
(2) punching press: adopt forcing press 6 to carry out punching press, by the step-feeding diel steel band is divided into two after through three step punching presses and does not link mutually and size is in full accord and two continuous profile of tooth billots 1 of type linearly;
(3) reel: two linear pattern profile of tooth billots 1 after the punching press directly are connected with the pay-off of up-coiler 4 with stagnant hopper 3 through guide frame 2, and on up-coiler 4, be wound into two circles and be the spiral helicine loose iron core 5 of pre-fixing turn, separate from profile of tooth billot 1 by shear again, during shearing, also by positioner make moulding loose iron core 5 initiating terminal be in same linear position by end, guide frame 2 is for being fixed on the guiding bracing frame more than the ground, stagnate hopper 3 for being opened in the groove of below ground, when the winding speed of profile of tooth billot 1 is slower than drawing velocity, profile of tooth billot 1 can be case of bending and be trapped in hopper 3 tops, thereby avoids influencing the coiling work of up-coiler;
