Abstract
The utility model belongs to the technical field of motor casing processing, and particularly relates to a motor enclosure drawing device for drawing motor casings on punches. The motor enclosure drawing device comprises a female die and a male die, wherein the female die is fixed with a slider of a punch, and the male die is fixed with a backing plate of the punch. The female die is provided with a drawing hole penetrating the female die and allowing the male die to pass. A chamfer is arranged between the drawing hole and an end face of the female die close to the male die. A support plate for holding an enclosure is connected to the male die. One end of the male die is matched with the enclosure, close to the female die. The distance between the inner wall of the female die and the outer wall of the male die is equal to wall thickness of the enclosure. The motor enclosure drawing device has the advantages that pressing rings in the enclosure drawing procedure are omitted, and the female die with modified inner-corner structure and taper can achieve enclosure fixing effect as the pressing rings, so that the pressing rings can be omitted. Besides, the motor enclosure drawing device is convenient to process, procedures are simplified, and parts loss is reduced.
Description
Technical field
The utility model belongs to the motor case processing technique field, especially relate to a kind of on punch press the motor case stretching device of stretching motor case.
Background technology
On punch press the processing motor case generally can be divided into sawing sheet, moulding, the cutting of stretching, little processing, as punching, jet-bedding, screw thread cutting etc.Wherein drawing process is the raw material sheet material that will cut out in the sawing sheet program, is drawn into the casing shape and size of appointment by drawing die.Present domestic drawing die generally adopts the blank holder drawing process, need to use blank holder at the downward position of punch, in drawing process, casing is stretched to designated shape under the common squeezing action power of blank holder and die, special construction due to position, blank holder termination, can prevent the casing play in drawing process, the phenomenons such as the wrinkling or distortion of the back cabinet of avoiding stretching occur, and blank holder can also play positioning action.
A kind of drawing die with blank holder now is provided; as notification number be: a kind of cold drawing die that the Chinese utility model of CN202239268U provides; belong to mould; die is fixedly connected with upper bolster; punch is fixed on die shoe by attachment screw, and blank holder is fixedly connected with die shoe by screw, and nitrogen spring is fixed on die shoe by attachment screw; nitrogen spring is fixedly connected with the blank holder lower end, and blank holder and punch are slidably connected.As shown in Figure of description 3, this drawing die is provided with blank holder 7, but in drawing die, the space h between die and punch is often very limited, this just can only use the thinner blank holder of wall thickness, thin blank holder processing technology is complicated, easily damages, and uses in addition the blank holder stretcher casing, the single amount of tension is less, the shape, the dimensional requirement that meet for casing is reached need to be carried out multi-drawing to casing, but a common casing product needs just drawing and forming of 4～6 procedures at least.
The utility model content
The utility model be mainly for existing with the existing blank holder of the drawing die of blank holder easily damage, stretching process is more, the problem that production cost is higher, provide that a kind of processing is easy, stretching process simplifies, the motor case stretching device that production cost reduces.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of motor case stretching device, comprise with punch press on the fixing die of slide block, and with the fixing punch of the backing plate on punch press, described die is provided with and connects die and can hold the stretchable holes that punch passes, be provided with chamfering between the end face of close punch and stretchable holes on die, be connected with the retainer plate of putting casing on punch, an end and casing near die on punch are complementary, and the inwall of die is identical with the wall thickness of casing to the distance between the punch outer wall.This motor case stretching device, the use of having removed blank holder in the casing stretching process is by the improvement to die integral angle structure and tapering, make it to reach the fixedly effect of casing as blank holder, thereby reached the purpose of inapplicable blank holder, simplified working process, saved accessory loss.
As preferably, chamfer angle is 20～35 °.Chamfer angle on die is 20～35 °, and satisfying is stretchable use needs.
As preferably, the fillet surface on die is that cambered surface is connected with the inwall of die, and the angular range of cambered surface is 40～65 °.Fillet surface on die is that cambered surface is connected with the inwall of die, and the stretching that casing can be level and smooth should according to the concrete thickness of casing product, decide this place's cambered surface angular dimension.
As preferably, described punch connects retainer plate and is connected with the retainer plate matched in clearance.Stripper plate can also play the role of positioning to punch support machine casing except being used for, and prevents the punch skew, affect the casing stretching.
As preferably, be fixed with guide pillar on described die, the end of guide pillar extends to the end of retainer plate.Die vertically moves down with slide block, and guide pillar moves down thereupon, and the promotion stripper plate moves down simultaneously.
Therefore, the beneficial effects of the utility model are: the motor case stretching device has been removed the use of blank holder in the casing stretching process, by the improvement to die integral angle structure and tapering, make it to reach the fixedly effect of casing as blank holder, thereby reached the purpose of inapplicable blank holder, process easy, simplify working process, save accessory loss.

The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
as Figure of description 1, shown in 2, a kind of motor case stretching device, comprise with punch press on the fixing die 1 of slide block, and with the fixing punch 2 of the backing plate on punch press, die 1 is provided with and connects die 1 and can hold the stretchable holes 3 that punch 2 passes, be provided with chamfering between the end face of close punch 2 and stretchable holes 3 on die 1, chamfer angle is 30 °, fillet surface on die 1 is that cambered surface is connected with the inwall of die 1, the angular range of cambered surface is 50 °, be connected with the retainer plate 4 of putting casing 6 on punch 2, punch 2 connects retainer plate 4 and is connected with retainer plate 4 matched in clearance, be fixed with guide pillar 5 on die 1, the end of guide pillar 5 extends to the end of retainer plate 4, an end and casing 6 near die 1 on punch 2 are complementary, the inwall of die 1 is identical with the wall thickness of casing 6 to the distance between punch 2 outer walls.
