Abstract
The present invention relates to a method for manufacturing hook shape of commutator with hook, which is used for manufacturing hook shape of commutator of AC/DC motor and DC motor. The method is characterized in that a special tool is used on stamping equipment, and a hook shape is cut and separated on the excircle of the commutator by using the cutting edge of the special tool. The method has simple production process, improves work efficiency and quality, obviously saves raw material consumption and reduces labor intensity, and can achieve the purpose of mass production with lower cost.
Description
The present invention relates to a kind of method that hook commutator (or claiming commutator) hook-type is made, be specially adapted to the hook-type manufacturing of universal motor, DC motor commutator.
" processing method of small-sized DC motor commutator " patent according to Japanese kokai publication sho 52-6905, utilized the side of small-sized DC motor commutator bobbin to pull into the outer rim of protrusion, be processed into required size with conventional method, also to excise the redundance of protrusion, cut flange again and just form suspension hook, also will make it to become whole commutator at last with compacting or other method.But such manufacturing process, complex procedures.For being separated with high insulating property materials such as mica between the commutator segment, and the hook-type manufacturing of the commutator of other internal structure is difficult to realize.
The objective of the invention is to use a kind of new method to overcome the deficiency of known technology, this method can process hook-type on whole commutator, be not limited by the blank shape of commutator and internal structure shape like this, during the processing hook-type, because of integral body forms, utilize its endoporus or cylindrical location to be very easy to, moulds of industrial equipment are greatly simplified.
The present invention finishes as follows, at first by known technology commutator assemble, moulding, by actual requirement size, earlier be processed into commutator cylindrical turning step-like, then to big end step cylindrical, at the dead slot that mills out on the milling machine between hook and the hook position, or with other way processing dead slot, on pressing equipment, use special tooling again, the protrusion part cutting and separating on the cylindrical behind the processing dead slot is gone out hook-type.Isolated hook-type to increase hook bottom width degree and deburring, has promptly been finished the manufacturing of hook-type through the ordinary skill shaping.
This method is that cutting and separating goes out hook-type on the commutator cylindrical, so even commutator internal structure difference and specification difference can be used this method processing hook-type equally.
The processing of use this method, the cutting and separating of hook-type can be carried out after dead slot first being processed between hook and the hook position or processing.
The hook-type that goes out with this method cutting and separating can not carry out shaping processing by actual requirement, promptly can be used as finished product and uses.
Method provided by the invention, compare with known technology, following advantage is arranged: use this method not need special installation, as long as by known technology assembling one cover special tooling, just can be on the whole cylindrical of commutator once the property cutting and separating go out hook-type, technology is simple, easy to operate, and the workman is not had special technical requirement.Because on whole commutator cylindrical, process hook-type,, has extensive applicability so not limited by commutator blank shape and internal structure shape.Except that above-mentioned advantage, can also save raw materials consumption, reduce cost remarkable in economical benefits.
Have following accompanying drawing further to explain this explanation:
Fig. 1: commutator is processed into step-like profile schematic diagram
Fig. 2: commutator mills out the schematic diagram of dead slot.
Fig. 3: the schematic diagram of commutator hook-type processing.Among the figure: (1) is commutator; (2) be die; (3) be mandrel; (4) be punch; (5) be pushing block; (6) be push rod; (7) be top board; (8) be India rubber.
Fig. 4: be finished product hook commutator schematic diagram.
Do the description of embodiment below in conjunction with accompanying drawing 3: the commutator 1 that is processed into as Fig. 2 shape is put into punch 4, and by mandrel 3 centering.The beginning punching press makes die 2 descending, and it is descending in punch 4 to promote commutator 1, because the effect of punch 4 upper knife edges can cutting and separating go out hook-type.
When die 2 is descending, pushing block 5 with push rod 6 and top board 7 simultaneously pressurized exercise India rubber 8 compressions down.After finishing the hook-type cutting and separating, die 2 promptly rises, and India rubber 8 restores to the original state, and by the effect of top board 7 and push rod 6, makes that the holder-on commutator ejects on the pushing block 5, finishes hook-type and separates.
After the hook-type of commutator is separated, by actual requirement again through the ordinary skill shaping, increasing hook bottom width degree, and deburring.
Claims (1)
1, a kind of method of hook commutator hook-type manufacturing, on the big end step of commutator cylindrical, use the blade of special tooling, cutting and separating goes out hook-type on pressing equipment, it is characterized in that: above-mentioned cutting and separating goes out the operation of hook-type and carries out after the commutator assembling is shaped to integral body.
