Abstract
The invention relates to a piercing die for a lamp shade, which comprises an upper die plate and a lower die plate, wherein a female die is arranged on the lower surface of the upper die plate; a male die and a retainer plate are arranged on the lower die plate; the male die is sleeved with the retainer plate; the retainer plate is mounted on the lower die plate by a buffer component; a cavity is formed in the female die; a die handle and a knockout rod are arranged on the upper surface of the upper die plate; the knockout rod is mounted on the die handle and extends into the cavity; the lower end face of the female die is inclined; and an inclined surface step adapted to the inclined end face is arranged on the retainer plate. With the adoption of the technical scheme, the piercing die is simple in structure and stable and convenient to operate; one step of punch forming is required only; the deficiency that a position of a side hole is inaccurate due to processing for many times is overcome; in addition, the piercing die is mounted stably with the lamp shade through a retainer plate structure, so that the piercing precision of the piercing die is improved; the product yield is increased; the production efficiency is improved; the manufacturing cost and the labor intensity are reduced; and the piercing die is reasonable and stable in structure, and deserves popularization and use.
Description
Technical field
What the present invention relates to is a kind of punching die, and what be specifically related to is a kind of lampshade punching die.
Background technology
Cold-punching mould is one of mould that extensively uses, and kind comprises perforating die, blanking die, bending die, Drawing Die etc., and the application of cold-punching mould is more and more extensive in recent years.It is low that cold stamping has a cost, and constant product quality can be processed multiple performance, the part of state.Simultaneously its application and the general restriction that also is subject to the aspects such as die life and production safety.
And in the lampshade production field, generally be to adopt one-shot primary drying hole to half-finished lampshade at present, or adopt artificial punching, its inconvenient operation to Lamp housing location inaccuracy, makes circular hole inclination or the position of its processing not right, affect its inefficiency, increase labour intensity, and punching positional precision on lampshade is low, is inconvenient to locate, make its machining hole large apart from position deviation, be difficult to cooperate with other products or install, thereby cause scrapping of whole product, increased production cost.
Summary of the invention
For the deficiency that exists on the prior art, the present invention seeks to be to provide a kind of can be easy to operate, simple in structure, the lampshade punching die that positioning accuracy is high, be used for the lampshade punching, make its accurate punching, one-shot forming, guaranteed the qualification rate of product, enhanced productivity.
To achieve these goals, the present invention realizes by the following technical solutions:
The lampshade punching die, it comprises cope match-plate pattern and lower bolster, lower surface at described cope match-plate pattern is provided with die, it is characterized in that, be provided with punch and the retainer plate that is enclosed within the demoulding on the described lower bolster, described retainer plate is installed on the lower bolster by buffer unit, described die is provided with die cavity, the upper surface of described cope match-plate pattern be provided with mould bright and be installed in mould bright on and extend to the knockout rod of die cavity, the lower surface of described die is inclined end face, is provided with the incline bench suitable with inclined end face on the described retainer plate.
According to above-mentioned lampshade punching die, wherein, described retainer plate is provided with and the cannular boss for the treatment of that punching lampshade cavity geometry is suitable, and described boss upper end is angled end-face, and described punch upper end is inserted in the hollow of boss.
The present invention passes through technique scheme, it is simple in structure, and stable operation, convenience only need one time punching molded, avoided the repeatedly coarse defective in process side hole site, and it makes it improve the punching precision, the raising product percent of pass by stripping board structure and the stable installation of lampshade, improved production efficiency, and having reduced production cost and labour intensity, it is rational in infrastructure, stable, is worth of widely use.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention;
Fig. 2 is cutaway view of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Referring to Fig. 1 and Fig. 2, present embodiment is the lampshade punching die, it comprises cope match-plate pattern 10 and lower bolster 20, lower surface at cope match-plate pattern 10 is equipped with die 11, die shank 12 is installed on its lower surface, at die shank 12 mobilizable knockout rod 13 is installed, this knockout rod 13 passes die shank 12 and cope match-plate pattern 10 extends in the die cavity 14 of die 11.
In the present embodiment, punch 21 and the retainer plate 22 that is enclosed within the demoulding 21 are installed on the lower bolster 20, retainer plate 22 is installed on the lower bolster 20 by buffer unit 24, and what this buffer unit 24 adopted is excellent power glue.The lower surface of described die 11 is processed as inclined end face, be provided with on the described retainer plate 22 with the suitable incline bench 25 of inclined end face and with the cannular boss 23 for the treatment of that punching lampshade cavity geometry is suitable, these cannular boss 23 upper ends are angled end-face, described punch 21 upper ends are inserted in the hollow of cannular boss 23, be convenient to treat the installation of punching lampshade, avoid its activity, increase stable, improve machining accuracy, and make it and treat that punching lampshade profile is adaptive.
When the present invention uses, to treat that the punching lampshade is enclosed within on the cannular boss 23 of lower bolster 20, then by matched moulds, the inclined end face of die 11 contacts and pushes incline bench 25 with incline bench 25, under buffer unit 24 effects, punch 21 is being treated punching lampshade upper punch hole forming.
The present invention passes through technique scheme, it is simple in structure, and stable operation, convenience only need one time punching molded, avoided the repeatedly coarse defective in process side hole site, and it makes it improve the punching precision, the raising product percent of pass by stripping board structure and the stable installation of lampshade, improved production efficiency, and having reduced production cost and labour intensity, it is rational in infrastructure, stable, is worth of widely use.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
