Abstract
The utility model relates to a lamp cover punching die. The lamp cover punching die comprises an upper template and a lower template, a concave die is arranged on the lower surface of the upper template, a convex die and a retainer plate which is sleeved on a stripping die are arranged on the lower template, the retainer plate is mounted on the lower template through buffer components, a mold cavity is formed in the concave die, a die shank and a material beating rod which is mounted on the die shank and extends into the mold cavity are arranged on the upper surface of the upper template, the lower end face of the concave die is an inclined end face, and inclined steps which are matched with the inclined end face are arranged on the retainer plate. According to the lamp cover punching die, the lamp cover punching die is simple in structure, stable in operation and convenient to operate, the defects that the position of a side hole is not accurate due to multiple processing is avoided because punching shaping is completed only in one time, due to the fact that the retainer plate structure is stably mounted on a lamp cover, punching accuracy is improved, product percent of pass is improved, production efficiency is improved, production cost and labor strength are lowered, the lamp cover punching die is reasonable and stable in structure, and is worth popularizing and using.
Description
Technical field
The utility model relates to a kind of punching die, 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.Its application simultaneously and the general restriction that also is subject to the aspects such as die life and production safety.
And in the lampshade production field, be generally employing one-shot primary drying hole to half-finished lampshade at present, or adopt artificial punching, its inconvenient operation is located inaccuracy to Lamp housing, 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 coordinate with other products or install, thereby cause scrapping of whole product, increased production cost.
The utility model content
For the deficiency that exists on prior art, the utility model purpose 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 utility model is to realize by the following technical solutions:
The lampshade punching die, it comprises cope match-plate pattern and lower bolster, be provided with die on the lower surface of described cope match-plate pattern, it is characterized in that, be provided with punch and the retainer plate that is enclosed within the demoulding on described lower bolster, described retainer plate is arranged on lower bolster by buffer unit, described die is provided with die cavity, be provided with on the upper surface of described cope match-plate pattern mould bright and be arranged on 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 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 utility model 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 utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, the present embodiment is the lampshade punching die, it comprises cope match-plate pattern 10 and lower bolster 20, die 11 is installed on the lower surface of cope match-plate pattern 10, die shank 12 is installed on its lower surface, mobilizable knockout rod 13 is installed on die shank 12, and 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 lower bolster 20, retainer plate 22 is arranged on 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 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, this 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 utility model 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 utility model 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.
Above demonstration 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 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.
