Abstract
The invention relates to a puncher pin positioning device of a punching press machine. The puncher pin positioning device comprises a mould handle, a square positioning hole, a mould handle fixing plate, a positioning pin, screws, an upper mould, a puncher pin and the like. The mould handle is of a cylinder and square integrated structure, the upper end of the mould handle is a cylinder which is fixed on the punching press machine by the tightening screws, the lower end of the cylinder is a square, the lower end of the square and the square positioning hole on the mould handle fixing plate are fixed through fit clearance, and therefore, the puncher pin can be disassembled and replaced conveniently. The upper mould is arranged at the lower end of the mould handle fixing plate, the upper mould and the mould handle fixing plate are positioned through the positioning pin and fastened through the screws, and the puncher pin is arranged on the lower end surface of the upper mould. During using of the puncher pin positioning device, when the puncher pin and a concave mould need replacing, the puncher pin and the concave mould can be replaced after disassembling the mould handle fixing plate and a lower mould, and position accuracy after the puncher pin and the concave mould are assembled is effectively guaranteed.
Description
Technical field
The present invention relates to a kind of positioner for punching press motor stamping, specifically a kind of drift positioner of punching forcing press.
Background technology
We know, at present, when the punching of punching electric machine rotor, generally adopt first blanking, and punching goes out outline and the rotor sheet endoporus of stator piece, then on one-shot machine, uses rotor sheet Internal hole positioning, respectively punching stator and rotor sheet.Like this, stator and rotor sheet has how many grooves, just necessary punching how many times, cause drift and die serious wear on mould, need to repeatedly dismantle drift and die, go to carry out again position correction after grinding cutting edge, cannot guarantee the positional precision of grinding front and back punching flute profile, affected product quality, and labour intensity is large, inefficiency.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and the drift positioner of a kind of accurate location, the punching forcing press that easy to operate, operating efficiency is high, stamping quality is good is provided.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of drift positioner of punching forcing press, be provided with die shank, cylinder, square, square locating hole, die shank fixed head, alignment pin, screw, upper mould, drift, it is characterized in that: die shank is cylinder and square integrative-structure, upper end is cylinder, cylinder is fixed on punching forcing press by holding out against screw, cylinder lower end is square, match with the square locating hole on die shank fixed head in square lower end, upper mould is located at die shank fixed head lower end, with alignment pin, position between the two, with screw, carry out fastening, the lower surface of upper mould is provided with drift.
The present invention is owing to adopting said structure, while utilizing punching forcing press punching motor stamping, only need dismounting upper/lower die, change after drift and die, by simple positioning instant, can use, and substantially do not change the position of mould on punch press, thus guarantee the accuracy of motor stamping position, improved product quality.The present invention is rational in infrastructure, simple and easy to do, efficiency is high, punching performance is good.
Accompanying drawing explanation
Fig. 1 is die shank front view of the present invention;
Fig. 2 is die shank top view of the present invention;
Fig. 3 is die shank fixed head of the present invention and upper mould cutaway view;
Fig. 4 is die shank fixed head and the upper mould top view of this reality invention.
In figure, be labeled as: 1. die shank, 2. cylinder, 3. square, 4. die shank fixed head, 5. upper mould, 6. alignment pin, 7. screw, 8. drift, 9. square locating hole.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, the present invention relates to a kind of drift positioner of punching forcing press, be provided with die shank 1, cylinder 2, square 3, square locating hole 9, die shank fixed head 4, alignment pin 6, screw 7, upper mould 5, drift 8, it is characterized in that: die shank 1 is cylinder 2 and square 3 integral structures, upper end is cylinder 2, cylinder 2 is fixed on punching forcing press by holding out against screw, cylinder 2 lower ends are square 3, match with the square locating hole 9 on die shank fixed head 4 in square 3 lower ends, upper mould 5 is located at die shank fixed head 4 lower ends, with alignment pin 6, position between the two, with screw 7, carry out fastening, the lower surface of upper mould 5 is provided with drift 8.
When the present invention uses, first the cylinder on die shank is fixed on punching forcing press by holding out against screw, then by die shank fixed head and upper mould by alignment pin and screw fastening, then the square of die shank below and the square locating hole on die shank fixed head are worked good, finally according to processing request, by lower mould and drift location.In use, while changing drift and die as need, only need die shank fixed head and lower mould dismounting change after lower, the position accuracy after can effective guarantee reinstalling.
Claims (1)
1. the drift positioner of a punching forcing press, be provided with die shank, cylinder, square, square locating hole, die shank fixed head, alignment pin, screw, upper mould, drift, it is characterized in that: die shank is cylinder and square integrative-structure, upper end is cylinder, cylinder is fixed on punching forcing press by holding out against screw, cylinder lower end is square, match with the square locating hole on die shank fixed head in square lower end, upper mould is located at die shank fixed head lower end, with alignment pin, position between the two, with screw, carry out fastening, the lower surface of upper mould is provided with drift.
