Description

Galvanoplastics plate aline mechanism for blanking die}

The present invention relates to a pole casting product punching device. More specifically, the electrodeposition plate positioning apparatus for master electrode plate for punching product made by electrodeposition of electroforming metal is improved to reduce the processing time compared to the previous one while accurately positioning the product manufactured in a negative shape with respect to the model. It is about.

The galvanoplastics processing method is to obtain a product having a roughness opposite to the model surface by electrodepositing the metal on the model to which the exfoliation coating is applied, and then separating the electrodeposited metal from the model. Electroplated metals such as Cu and Ni may be used as model materials, or non-metallic models may be used. In this case, in order to provide conductivity to the surface of the model, graphite powder or copper powder may be applied or gold foil or silver foil may be used. It is known to coat.

In other words, a model having surface conductivity is placed in an electrolytic cell and an electric current flows to allow electrodeposition to occur on the surface of the model, followed by removal of the electrodeposited metal that is negatively attached to the surface of the model. will be.

In this way, it is possible to reproduce type casting models, record discs, print prints, portraits, and ornaments, and to manufacture keypads such as mobile phones. In particular, the electroplating process for manufacturing keypads has a surface conductivity nickel plate. On one surface selected from a brass plate, a chrome plate, a wooden plate, a resin plate, a rubber plate, and the like, a model plate with a certain shape carved in an embossed shape is provided. In addition, after masking the other surface, the electrodeposited layer of the negative shape is electrodeposited to the corresponding surface of the model plate according to the electrolytic action in the electrolytic cell, and the electrodeposition layer is peeled off from the model plate, and thus the master electrodeposition plate is peeled off as described above. Partially cut or punched as needed to obtain the desired product.

In addition, in order to fix the position of the master electrodeposition plate on the punching mold for punching, the guide hole must be formed by drilling the left and right sides of the punching portion of the master electrodeposition plate. The dowel pin is to be fitted in the mold.

On the other hand, the punching die device as described above is usually composed of the upper mold portion 100A to be controlled to move up and down, and the lower mold portion 100B fixed below as shown in FIG.

The upper mold portion 100A includes a stripper 120 and an upper holder 110 which fixes the upper portion 100A at an upper portion thereof so as to be movable upward and downward. Of course, conventional press parts such as punch packing 116, punch holder 117 and shank 118 are additionally provided on the upper holder 110.

The lower die portion 100B has a die 130 having a punch hole 132 and a post hole 136 coupled to the lower holder 140, and left and right guide alignment pins 34 are fixedly installed.

The stripper 120 has an alignment pin escape hole 122, a punch guide hole 124, and a post guide hole 126 into which the guide alignment pin 134 is inserted, and the upper holder 110 has the punch. A punch 112 inserted into the guide hole 124 and a guide post 114 inserted into the post guide hole 126 are provided.

In this way, the guide hole (1a) pre-formed in the master electrodeposition plate (1), which is the main product, is fitted and fixed to the guide alignment pin (134), and then the punching product punching process by punching. Will be done. In order to obtain a pole product with a hole inside, a second punching process of a piercing punch (inner hole punch) and a blanking punch (outer rim punch) is performed.

As a problem of the conventional electric product punching device as described above, the time required for drilling the guide electrode 1a in the master electrodepositing plate by manual processing to fix the position of the master electrodeposition plate when the electric product is punched out. This takes a lot of problems and low fish yield had a problem that the product yield is significantly lowered, and also has a problem for the manufacturing limit of the ultra-precision can not precisely control the position of the master electrodeposition plate is disposed for punching.

The present invention has been made in order to meet the conventional needs as described above, the object of the present invention is to eliminate the need for pre-punching operation for fixing the master electrodeposition plate to the mold at the time of punching, the number of manufacturing process and manufacturing operation By greatly shortening the time, it is possible to expect an improvement in productivity. In addition, workability can be improved by eliminating the task of having to fix the positioning guide pin of the punching die in the guide hole. As the position of the master electrodeposition plate can be precisely adjusted, an object of the present invention is to provide a punching device that overcomes the limitation of manufacturing high precision products.

Other objects and advantages of the invention will be described below and will be appreciated by the embodiments of the invention. In addition, the objects and advantages of the present invention can be realized by means and combinations indicated in the utility model registration claims.

In order to achieve the above object, the present invention has been devised in consideration of the need for the secondary punching of the piercing and blanking of the master electrodeposition plate, the electric pole for positioning the master electrodeposition plate in two ways during this secondary punching process It has been proposed as a positioning device for punching products.
