Description

The high-speed punching mold which uses a shaft form}

The present invention relates to a high-speed punching mold using a shaft method, and more particularly, to assemble a mold in a shaft method to maximize the stability of assembly and operation, to protect the stripper during punching, and to change the direction and the front and rear of the die. The present invention relates to a high-speed punching mold using a shaft method that can extend the life of the die to improve productability.

In general, in a device having a deployment effect transistor (FET) and an electronic component such as a chip component such as a resistor or a capacitor, there is a reduction in the weight, size of the product and a large increase in operating frequency. It has been made lighter, thinner and shorter.

These small electronic components are automatically inserted into the circuit board. In general, in order to continuously supply the electronic components to the automatic insertion device for automatically inserting the electronic components on the circuit board, the electronic components are regularly spaced to accommodate the electronic components. An electronic component carrier tape having rectangular holes, that is, receiving holes, is used.

In addition to the above-mentioned accommodation hole, the carrier tape made of paper wound around a circular reel has a circular transfer hole, that is, a transfer hole, for transferring the carrier tape at an accurate pitch.

Inserting a protective tape on the other side prevents the detachment of electronic components.

In the conventional processing mold apparatus for processing electronic parts such as the carrier tape, a material cut from the carrier tape is attached to the processing end of the punches during drilling, and the material also rises when the punch rises with respect to the lower mold. And then, when the feed hole or the receiving hole is machined back into the carrier tape with the punches, the cut material is attached to the processing end of the punch, which may cause machining defects, and sometimes the diameter of the punches is small. The punches may be shaken, which causes the punch and the lower mold to collide with each other by hitting the carrier tape and the upper surface of the lower mold without causing the punch to settle in the mold through-hole of the lower mold. There was a problem that is broken.

In order to improve the durability of the lower mold from the punching of the punch, a mold apparatus of a type for seating the guide plate on the upper surface of the lower mold is used to solve the above problem, but the end of the punch and the guide plate The cost of replacing the guide plate, which is relatively expensive due to abrasion due to friction with the inner wall of the guide hole, is disadvantageous. In order to replace the guide plate itself, the lower mold and the guide plate of the mold apparatus are dismantled and reassembled. There was a problem of low labor productivity due to the complicated work process.
