A fine punching device comprises a stationary die 4 with a counter punch 7 mounted in the die opening 6 and a punch 19 which extends through a contact plate 14 formed with a ring of teeth 17 and mounted in a reciprocable punch table, the cutting edge 12 around the die opening 6 being substantially convex, Fig. 3. Instead of a curve the cutting edge may comprise three faceted faces in planes (23), (24) and (25), Fig. 2 (not shown). In use, the punch table is moved upwardly with a workpiece between the die 4 and contact plate 14, the counter-punch 7 being first pushed into the die opening 6 until its surface 21 is level with the die surface 8. The workpiece is then clamped between the die and the plate 14, the teeth 17 penetrating the workpiece to prevent its displacement during simultaneous upward movement of punch 19 and counterpunch 7. The blank thus formed, which is said to have a smooth edge, remains in the die opening 6 when the punch 19 is lowered and is ejected by the counterpunch 7. The die 4 is preferably formed of hard porous metal, e.g. sintered or cemented carbides and lubricant fed to the die opening 6 and cutting edge 12 forms a deposit in the pores which helps to retain a film of lubricant between the die 4 and the workpiece during punching.

A holder of sturdy construction is provided onto which the thin die plate is removably mounted. Slidably positioned within the holder is a reciprocating support block which, upon blanking operation, underlies the thin die plate in order to reinforce it against the impact of the punch. After the blanking cycle, the support block is moved either to eject the part blank or to allow the latter to fall through an opening in the holder.

전방압출 천공성형에 의해 고온블랭크에 종횡비(길이/직경)이 5전후의 깊은 구멍가공을 높은 정밀도이면서 한 공정으로 행할 수 있는 중공금속제품의 제조방법과 제조설비를 제공한다. The present invention provides a method and a manufacturing equipment for hollow metal products in which high-temperature blanks have a high-precision aspect ratio (length / diameter) of about 5 deep holes in one process with high precision. 외형이 일정한 형상으로 단조가공된 고온블랭크를 하형다이스에 고정하고, 천공펀치, 유지가이드, 하형다이에 동축선상으로해서 윗금형에 고정하고, 그 윗금형의 하강에의해 유지가이드로 고온블랭크를 유지한 채로 이면서 동시에 유지가이드의 구멍에서 천공펀치를 구속한 상태로 천공펀치를 가압하고, 천공펀치의 횡변위를 방지한다. 천공펀치가 최하위위치또는 그 근방에 도달하면 그 선단은 리시버다이의 구멍에 들어가며, 구멍 뚫기를 행한다. Fix the forged high temperature blank to the lower die with fixed shape, and fix it to the upper mold by drilling punch, retaining guide and lower die coaxially, and maintain the high temperature blank with the retaining guide by lowering the upper mold. At the same time, the punch is punched in a state in which the punch is held in the hole of the retaining guide, thereby preventing the lateral displacement of the punch. When the punch punch reaches the lowest position or its vicinity, the tip enters the hole of the receiver die, and the hole is punched out.
