Description
Technical field
The present invention relates to a kind of commutator manufacturing equipment of motor, be specifically related to a kind of interior hook organisation of working of cylinder type commutator segment group.
Background technology
At present, the known commutator cylinder type commutator segment group manufacturing process with dovetail is: by the Warm Extrusion process of copper wires and through twice drawing process (namely twice drawing process makes the dimensional accuracy of the banding pattern commutator segment group after drawing reach necessary requirement), make the cylinder type commutator segment group with dovetail by punch press and particular manufacturing craft through punching process again.In the dovetail process using mould punching cylinder type commutator segment group, the dovetail gone out is owing to easily coming off by drag effect and being out of shape, and punching procedure quality is unstable, the adhesive strength that the commutator segment group that directly can have influence on subsequent handling is combined with moulding compound; Meanwhile, the interior hook hook groove depth height inequality and the interior hook width that also there will be commutator segment group are uneven, cause the outer circularity of commutator product inadequate, need to carry out Excircle machining process again; And the copper material that punching goes out end material directly becomes waste material, and cause raw materials consumption large, production cost is high.When the size dimension of punching production equipment and dedicated processing mould is limited, the commutator segment group of this structure is not suitable for the large commutator product of size, is only applicable to the commutator product of outside diameter at below 30mm.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of dovetail made not yielding and come off, the plough of the interior hook hook groove depth of commutator segment group and the cylinder type commutator segment group of interior hook even width splits interior hook mechanism.
Object of the present invention realizes by following technical solution: interior hook mechanism split by the plough of cylinder type commutator segment group, comprise upper bolster, die shoe, described die shoe is equipped with rotating disk by power transmission shaft, this rotating disk is equipped with some fixed covers, on described die shoe and with corresponding position, fixed cover position be equipped with colter bar, under split interior hook mould, this colter bar is equipped with colter, described upper bolster is equipped with under split interior hook mould position corresponding on split interior hook mould.
Adopt the present invention and supporting with stamping machine after, hook cold extrusion process in the plough of colter, and upper and lower upper and lower cold extrusion process of splitting interior hook (also can claim piercing inner-hook) of splitting interior hook mould, the final obtained cylinder type commutator segment group with dovetail, interior hook hook groove depth and interior hook even width.Its tool has the following advantages: utilization rate of raw materials is high, does not have the waste material that former punching operation is gone out, and saves material about 30%; Dovetail in commutator segment group can not be out of shape or strength damage, thus ensure that the mechanical strength of commutator segment group; The interior hook hook groove depth of commutator segment group and interior hook even width, make the outer circularity of commutator product good, do not need to carry out Excircle machining again, hook groove shapes in needed for can also directly being formed on the dovetail of commutator segment group, can increase the adhesive strength of commutator segment group and moulding compound; 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 of plurality of specifications.

Embodiment
Below in conjunction with drawings and the embodiments, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, interior hook mechanism split by the plough of cylinder type commutator segment group of the present invention, comprise upper bolster 1 (containing fixed head), die shoe 2 (containing template), described die shoe 2 is equipped with rotating disk 4 by power transmission shaft 3, this rotating disk 4 is equipped with some fixed covers 5, on described die shoe 2, and with corresponding position, fixed cover position (successively), the outer hook mould 11 that rises is housed, colter bar 6, under to split interior hook mould 10 (left, right two covers), this colter bar 6 is equipped with colter 7 and (on described colter 7, seeker 8 is also housed, to guide workpiece alignment position), described upper bolster 1 is equipped with under split interior hook mould position corresponding on split interior hook mould 12 (for left, right two covers).
Wherein, described upper bolster 1 is also equipped with guide pillar 14, described die shoe 2 is also equipped with rise outer hook mould 11, counterdie positioning sleeve 9, described upper bolster 1 is equipped with material discharging rod 15 (and corresponding with the position of fixed cover) at upper side (later process) place of splitting interior hook mould 12.Described die shoe 2 has workpiece slot 13 at side (preceding working procedure) place of the outer hook mould 11 that rises, outside the workpiece slot 13 on described die shoe 2, is connected with workpiece pusher 20 (for delivery cylinder type commutator segment group).Described workpiece pusher 20 (can be left and right two covers) comprises slide block holder 21, this slide block holder 21 is equipped with pusher power source 22 (for pusher cylinder), workpiece slide rail 24 is equipped with at this slide block holder 21 built with the slide block pressing plate 23 (containing slide block) be connected with pusher power source, this slide block holder 21 in the side edge of slide block pressing plate 23.For putting cylinder type commutator segment group workpiece 25 in workpiece slide rail 24, and by its free landing.The cylinder type commutator segment group workpiece 25 that landing puts in place with movable slider pressing plate by pusher power source 22 (pusher cylinder) is pushed in the workpiece slot 13 on die shoe 2.
The plough of cylinder type commutator segment group of the present invention is split interior hook mechanism and is externally refilled on the stamping machine of suitable tonnage.When cylinder type commutator segment group workpiece (has had outer hook, its outer hook is down) in the workpiece slot 13 that is pushed to die shoe 2 time, rotating disk moves down and is embedded in fixed cover 5 by workpiece, turntable rotation makes the workpiece in fixed cover forward to rise the top of outer hook mould 11, upper bolster, die shoe and rotating disk carry out matched moulds by stamping machine, its outer hook process of spreading is carried out to workpiece, stretches into and split interior hook needs to be conducive to colter.Then, upper bolster, die shoe die sinking, rotating disk rotates the top making the workpiece in fixed cover forward colter 7 again to again, upper bolster, die shoe and rotating disk carry out matched moulds, counterdie positioning sleeve carries out effective location simultaneously, guide pillar guides, seeker effectively guides location, the inwall being extend into cylinder type commutator segment group workpiece by the colter 7 on colter bar 6 carries out ploughing interior hook cold extrusion process, first plow on roll type commutator segment group inwall as Niu Li field hook in commutator segment group initial model (i.e. blank, as shown in Figure 4, Figure 5).Then, upper bolster, die shoe die sinking, workpiece is rotated to upper and lower splitting between interior hook mould and locates by rotating disk again, upper bolster, die shoe and rotating disk carry out matched moulds, split interior hook mould carried out upper and lowerly splitting interior hook cold extrusion process by upper and lower respectively, finally form the cylinder type commutator segment group with dovetail (i.e. interior hook), interior hook hook groove depth and interior hook even width.The concrete shape (as shown in Figure 6, Figure 7) of commutator segment group dovetail, this is cold extrusion processing mode, and multiple workpiece can process simultaneously successively.
