Description
【発明の詳細な説明】 本発明は、ワークのパリなし打抜法に関する。[Detailed description of the invention] The present invention relates to a method for punching a workpiece without flashing.

要とする場合が多い。Conventionally, when punching is performed from a temporary metal phase to obtain a workpiece 3α, there is a paris 8 on the punching side as shown in Figure 1 @) and (b).
A fractured surface 7 is generated, which is uneconomical as it requires post-processing in practice, and the fractured surface is also disadvantageous in side use and often requires secondary processing.
この発明は、上記の欠点を除去するため金型切刃構造只

ことを目的としたものである。The purpose of the present invention is to eliminate the above-mentioned drawbacks by controlling the structure of the cutting edge of the mold and by extracting and returning the mold to obtain a workpiece without burrs.
以下本発明を図面にもとづいて詳細に説明する。The present invention will be explained in detail below based on the drawings.
第2図において、ダイ1bは、あらかじめ10チ〜20

〜5ost半抜きに際し、ワーク3bに破断の起きない
条件を有するものである。In FIG. 2, the die 1b has 10 to 20 die in advance.
The condition is such that the workpiece 3b does not break when the punch 2 punches the workpiece 4 by 65 inches to 50cm and a half by applying an radius of t4t.
パンチ2は、被加工材の材質によフロ5〜80%tの範
囲で突込み深さを任意に選び、打抜途中で停止、ワーク
3bを半抜き状態にして、パンチ2は上死点に戻る。The punch 2 arbitrarily selects the plunge depth in the range of 5 to 80% of the flow depending on the material of the workpiece, stops in the middle of punching, leaves the workpiece 3b in a half punched state, and punch 2 reaches the top dead center. return.

シュバックする。Next, the half-blanked workpiece 3'''e is returned to the workpiece 4 at the next stage on the upper surface of the die, and is connected to the workpiece 3b to generate the partial phenomenon t''LfcLfc, as shown in Fig. 3. The workpiece is returned to the workpiece 4 in this manner, and the workpiece is completely pushed back.

なるものである6 (第4図参照〕。A break occurs in a part of the reverse shear surface of workpiece 3b, but
It is separated from the workpiece 4 and becomes an independent workpiece 3b, and a burr-free product is constructed.By removing the blade from the workpiece side, the burr-free workpiece 3b is completed. (See Figure 4).
以上のごとく、本発明によnば、金型切刃部Rのg理、

。As described above, according to the present invention, the processing of the mold cutting edge R,
Clearance control, half-blanking depth control, and back-blanking processing are all performed, so it has the effect of easily producing workpieces without burrs.

ことを特徴とするワーク打抜法。This is a punching method for obtaining a workpiece from a metal plate material, and the clearance between the punch and die is θ ~ 5 inches, and the die has a radius of 10% to 20% of the thickness of the workpiece.
During punching, the depth of the punch is kept at 65 to 80 inches, which is the thickness of the workpiece, and then the workpiece is returned to the corrugation machine to create sagging and sheared surfaces on the upper and lower surfaces of the workpiece. A workpiece punching method characterized by the following.
