Abstract

PURPOSE:To punch continuously an uneven punching plate by providing a downward projection on a punch part for punching the vicinity of a base part of a projecting part of the tip of the advancing rear side of punching part of a material, and providing a recessed groove on a stripper part for a die corresponding to this projection. CONSTITUTION:When punching a punching plate by using a punching die, a die use stripper 32 having a recessed groove 33 corresponding to a projection 31 descends by a prescribed pressure. After a narrowed part 34 has been made, eve if a slot cutter 24 of a punch depresses a projecting part 21 to the bottom dead center, the projecting part 21 does not execute horizontal permanent shaping to a rear material, and when a slide cam is drawn upward, the projecting part 21 of the tip springs back and bends upward by residual stress remaining in the narrowed part 34. Accordingly, an influence of flapping of a material is eliminated, and a trouble caused by a fact that the projecting part 21 of the tip is caught by a cutter leading edge of a shaft hole, and a minute step difference or gap between the die use stripper and a die is prevented.

ゆる単動打抜を余＋ａなくしている。Moreover, when the size of the punched board (1) becomes large (2), there is a need to shorten the punching manufacturing time by increasing the speed including the feed of the material (8). Increase in the speed of the contact surface between the roller controller @ and material (8) (from 2, Fig. 4)
As shown in the enlarged view (2) Material (8) (2) A waving phenomenon occurs, albeit minutely. Therefore, when the leading edge of the convex portion Vυ at the tip is wavy, F becomes Di (2 is the shaft hole cutting edge The advancing leading edge of the cutting edge (1) becomes thick (==. Also, the shaft hole (2) is small, and the tip convex part υ of the connected material (8) crosses the advancing leading edge of the shaft hole cutting blade. Even if it goes over it, there is a slight difference in level or gap between the lower board stripper and the F-type in the front (= it may bend when pulled). In this case, as shown in FIG. If the bent part and the material (8) are punched in two pieces, it may cause wear and tear on the cutting edge, and it will take a lot of time to repair the die. This will damage the high-definition cutting die and affect its lifespan.On the other hand, the cutting board (1) itself will be a defective product due to the hair shape of the point-cutting part.Also, as shown in Fig. 8 (2, If the tip convex part ■υ of the material (8) does not come off the advancing leading edge (6a) of the shaft hole cutting blade, the roller feed uI
The material (8) sent from the lower mold (6) is in a state where it is greatly raised above the upper surface of the lower mold (6).In this state, if the take-out device holder u'5 enters between the upper and lower molds (2), the material (8) )'s climax 9
A collision occurs between the part (to) and the ejector cradle Vω, resulting in a major accident in which the ejector cradle US and its related mechanisms are also damaged. In order to avoid these problems (2. When manufacturing a punched plate with large dimensions for a bridge shape), check the condition of the curved part while using the continuous punching device shown in Figures 1 to 4. Since the correction of one bent part must be carried out by the cutting operator, automatic continuous punching is not possible, and so-called single-acting punching is no longer possible.

。The present invention (in particular, a continuous punching device for automatically and continuously punching a sheet with an uneven outer periphery using a press from a band-shaped metal sheet material (2) The upper part of the die that punches out the vicinity of the base of the convex part (it has a convex similar to the nid, and its convex part corresponds to 2). When punching a blanked board, the protrusions and the four-shaped edges of the material are pressed together near the base of the protrusion at the tip, and when the protrusion at the tip is bent upward (twice), when feeding the material, the tip This prevents the convex portion from getting caught on the advancing leading edge of the shaft hole cutting blade or the advancing leading edge of the stripper for the shed, and enables automatic continuous punching.
