A contour blanking hole and a middle hole are formed in the bottom die, and are in the same straight line;two positioning blocks are arranged on two sides of the contour blanking hole respectively; and two positioning punched holes are formed on two sides of the middle hole respectively. Compared with theprior art, the machine can realize one-time processing to metal, can punch and shear continuously, reduces working procedures of process and greatly improves the processing efficiency of products. Inaddition, multiple die punching processes can be carried out synchronously.

Description

Continuous Die Machine

Technical field:

The utility model relates to a continuous punching machine.

Background technique:

In the process of metal jewelry processing, it is often necessary to process some metal jewelry with special shapes, such as plum blossom shape, heart shape and other irregular shapes. Generally, one-time stamping is used to process such jewelry, as shown in Figure 1. First, the The metal sheet to be processed is placed at the irregular punching hole 101 on the single-punch blanking die 1, and then stamped to obtain an ornament with the same shape as the punching hole 101.

And if need opening for irregular shaped jewelry, then also need to carry out punching through another set of punching die again, see Fig. , where the central concave hole 201 is the same size as the ornament, and the center is provided with an opening 202, and then punched through a punching die to make holes on the ornament.

Therefore, the processing of irregular metal ornaments with holes requires the use of the above two sets of molds, which cannot be formed at one time, and has the problems of cumbersome processing and long production time.

Invention content:

In order to solve the above problems, the purpose of this utility model is to provide a continuous punching machine, which can process irregular metal ornaments with holes at one time.

In order to achieve the above object, the utility model mainly adopts the following technical solutions:

A continuous punching machine, comprising a bottom mold, the bottom mold is provided with a shape blanking hole and a middle hole, and the shape blanking hole and the middle hole are located on the same straight line, and each side of the shape blanking hole is provided with a A positioning block; a positioning punching hole is provided on both sides of the middle hole.

The positioning punching hole and the positioning block are located on the same straight line.

The utility model firstly punches a punching hole on the metal sheet, and then directly moves the punched metal sheet down between the positioning blocks for punching, and punches the metal sheet into a shape corresponding to the positioning punching hole. A good punch is in the middle of the above shapes. Compared with the prior art, the utility model can realize continuous punching through one-time molding, can form continuous feeding, and greatly improves the efficiency of metal cutting.

Description of drawings:

Fig. 1 is the structural schematic diagram of existing single punch blanking die.

Fig. 2 is a structural schematic diagram of an existing punching die.

Fig. 3 is a structural schematic diagram of the continuous punching machine of the present invention.

Instructions in the figure: single punch blanking die 1, irregular punching hole 101, punching die 2, concave hole 201, opening hole 202, positioning block 3, positioning punching hole 4, blanking hole 5, middle hole 6, bottom Die 7.

Detailed ways:

The utility model will be further described in conjunction with accompanying drawing 3 below.

The utility model relates to a continuous punching machine, which is mainly used for continuously punching precious metal strips or metal sheets, especially for punching irregular metal sheets. It mainly includes a bottom mold 7, the bottom mold 7 is rectangular, and its four corners are provided with screw holes, so that the bottom mold 7 is fixed; the center of the bottom mold 7 is provided with a middle hole 6, the Positioning punching holes 4 are respectively arranged on both sides of the middle hole 6, and the middle hole 6 is located between the positioning punching holes 4; and a shape blanking hole 5 is also arranged on the same line as the above-mentioned middle hole 6, the shape falling The material hole 5 is used for the external shape of the product required for stamping and forming. In this embodiment, the quincunx shape is used as an example for illustration, and the two sides of the above-mentioned shape blanking hole 5 are respectively provided with raised positioning blocks 3, which are mainly used for The metal sheet to be processed is clamped between the two and just positioned on the shape blanking hole 5, so as to punch out a product having the same shape as the shape blanking hole 5.

The positioning punching holes 4 on both sides of the above-mentioned middle hole 6 and the positioning blocks on both sides of the shape blanking hole 5 are on the same straight line, and the distance formed between the two positioning punching holes 4 is the same as that formed between the two positioning blocks 3. The spacing is the same, which is to ensure that the metal sheet or metal strip can enter the second die smoothly after the first die procedure.

When it is necessary to punch metal sheets or metal strips, first feed the metal sheets or metal strips from top to bottom, punch through the middle hole 6, and remove the excess parts on both sides through positioning punching holes 4, and then the middle part Then continue feeding to the profile blanking hole 5 places between the positioning blocks 3, carry out stamping die, can punch out the metal ornament identical with profile blanking hole 5 shapes this moment, and then be the punching hole in the middle of this metal ornament.

Through the above-mentioned method, the device can realize one-time processing of metal, multiple die processes can be carried out simultaneously, continuous punching and shearing can be performed, the speed is fast, the processing steps are reduced, and the efficiency of product processing is greatly improved.

Above, a kind of continuous die machine provided by the utility model has been introduced in detail. In this paper, specific examples have been used to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model. method and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as Limitations on the Invention.
