Abstract
A trimming press working apparatus 1 includes a trimming means 6 for cutting a plate material 2 along a trimming line 5 which divides a product portion 3 from a non-product portion 4 in the plate material 2; a scrap cutting means 9 for cutting the non-product portion 4 along scrap severing lines 7 each intersecting the trimming line 5 to make the non-product portion 4 into a plurality of scrap pieces 8; and a pad 10 for pressurizing and restraining the product portion 3 of the plate material 2.
Claims6
A trimming press working apparatus comprising:
- trimming means for cutting a plate material along a trimming line which divides a product portion from a non-product portion in the plate material;
- and
- scrap cutting means for cutting the non-product portion along a scrap severing line intersecting the trimming line,
- said trimming means including one trimming press die means having a cutting blade extending along the trimming line and another trimming press die means for cutting the plate material along the trimming line in cooperation with the cutting blade of said one trimming press die means,
- said scrap cutting means including one scrap cutting press die having a cutting blade extending along the scrap severing line and another scrap cutting press die having a cutting blade extending along the scrap severing line so as to cut the non-product portion along the scrap severing line in cooperation with the cutting blade of said one scrap cutting press die,
- said another trimming press die means including main trimming press die means having a cutting blade extending along a remaining trimming line portion excluding a trimming line portion extending on a side of a cutting blade of one scrap cutting press die in a vicinity of an intersecting portion between the trimming line and the scrap severing line, so as to cut the plate material along the remaining trimming line portion in cooperation with the cutting blade of said one trimming press die means, and auxiliary trimming press die means having a movable cutting blade disposed so as to extend along the trimming line portion extending on the side of the cutting blade of said one scrap cutting press die and to be movable relative to the cutting blade of said main trimming press die means, so as to cut the plate material in cooperation with the cutting blade of said one trimming press die means along the trimming line portion extending on the side of the cutting blade of said one scrap cutting press die in the vicinity of the intersecting portion between the trimming line and the scrap severing line,
- said auxiliary trimming press die means having liquid pressure generating means for imparting to the movable cutting blade a cutting force based on compressible liquid pressure.
