Abstract
The utility model discloses one " 7 " font commutator segment cold extruding mechanism, comprise mold base (4), at described mold base built with extrusion moduling mould (5), one end of this extrusion moduling mould connects with extruding drift (3), its other end connects with discharge component (13), the head of described extruding drift (3) connects with one end of extrusion moduling mould (5) in " falling 7 " font structure, has extruding die cavity (12) in described extrusion moduling mould (5).The utility model utilization rate of raw materials is high, the waste material not having former punching to cut operation to go out, and saves material about 30%; The sharp processing of commutator segment is even, precision is higher, can not be out of shape or strength damage, ensure its mechanical strength; Owing to being cold extrusion process, do not limit by mould size, not by the restriction of commutator product size specification, be applicable to the commutator segment processing of plurality of specifications.
Description
Technical field
The present invention relates to a kind of commutator manufacturing equipment of motor, be specifically related to a kind of commutator segment organisation of working of cylinder type commutator.
Background technology
At present, the known cylinder type commutator manufacturing process of " 7 " font commutator segment is: by the Warm Extrusion of copper wires and through twice drawing process (namely twice drawing process makes the dimensional accuracy of the banding pattern commutator segment after drawing reach necessary requirement), cut (punching) by punch press and particular manufacturing craft through punching again and process and make " 7 " font commutator segment.In use mould punching process, the copper material end material that punching goes out directly becomes waste material, and cause raw materials consumption large, production cost is high.Meanwhile, also easily occur that the punching size height of commutator segment is uneven, affect its machining accuracy.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of and can save commutator segment raw material, " 7 " font commutator segment cold extruding mechanism that commutator segment machining accuracy is high.
Object of the present invention realizes by following technical solution: " 7 " font commutator segment cold extruding mechanism, comprise mold base, at described mold base built with extrusion moduling mould, one end of this extrusion moduling mould connects with extruding drift, its other end connects with discharge component, the head of described extruding drift connects with one end of extrusion moduling mould in " falling 7 " font structure, has extruding die cavity in described extrusion moduling mould.Described discharge component comprises discharge arm, and described discharge arm connects with the end of extrusion moduling mould and corresponding with extruding forcer position, this discharge arm by block with make bar and be connected.
Adopt the present invention and supporting with stamping machine after, to be entered in extrusion moduling mould by extruding drift and by the commutator segment in it by cold extrusion process, make " 7 " font commutator segment of required form, then by discharge arm propelling, extruding ram retracts, this commutator segment is released outside extrusion moduling mould.Its tool has the following advantages: utilization rate of raw materials is high, the waste material not having former punching to cut operation to go out, and saves material about 30%; The sharp processing of commutator segment is even, precision is higher, can not be out of shape or strength damage, ensure its mechanical strength; Owing to being cold extrusion process, do not limit by mould size, not by the restriction of commutator product size specification, be applicable to the commutator segment processing of plurality of specifications.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention " 7 " font commutator segment cold extruding mechanism.
Fig. 2 is the side direction view (it is built with commutator segment) of Fig. 1.
Embodiment
Below in conjunction with drawings and the embodiments, the present invention is described in further detail.
As shown in Figure 1 and Figure 2, the present invention " 7 " font commutator segment cold extruding mechanism, comprise mold base 4, at described mold base 4 built with extrusion moduling mould 5, one end of this extrusion moduling mould 5 connects with extruding drift 3, its other end connects with discharge component 13, and the head of described extruding drift 3 connects with one end of extrusion moduling mould 5 in " falling 7 " font structure (with extrusion process " 7 " font commutator segment).Described discharge component 13 comprises discharge arm 7, described discharge arm 7 connect with the end of extrusion moduling mould 5 and with extruding drift 3 position corresponding (being on same level line), this discharge arm 7 by block 9 with make bar 11 and be connected.
Wherein, there is in described extrusion moduling mould 5 extruding die cavity 12, for placing the commutator segment needing processing; Described discharge arm 7 is contained in discharging fixed block 8, and this discharging fixed block 8 connects with block 9; Described extruding drift 3 is contained in drift fixed block 2, and this drift fixed block 2 connects with die shank 1.
Described mold base 4 (being contained on mold base mounting blocks 10), die shank 1, make bar 11 and be all contained on the stamping machine of corresponding processing tonnage.As shown in the figure, first, the banding pattern copper material through Warm Extrusion, drawing process is sheared, make tetragonal commutator segment and enter in the extruding die cavity 12 of extrusion moduling mould 5 through feeding; Then, the extruding drift 3 with " fall 7 " font head to enter to the right in extrusion moduling mould 5 and by tetragonal commutator segment by cold extrusion process, makes " 7 " font commutator segment 6; Then, make bar 11 and work and by block 9, discharge arm 7 advanced left, extrude drift simultaneously and also retreat left, finally " 7 " font commutator segment of completion of processing is released outside extrusion moduling mould 5.
