METAL DIE DEVICE FOR PRODUCING HEMMING CONTAINER

摘要

PURPOSE:To provide the titled device of orderly feeding method for planning the elevation in production efficiency and cost reduction by constituting to perform a cut bend work in right angles of the whole periphery of the bottom face of a drawing formation part from the strip steel plate under transfer and to perform a bend work to the inner side from the right angles after positioning then. CONSTITUTION:The forming part 11' of a container shape worked with drawing of the hoop 9 to be fed out at the same pitch is fixed by a pad 29 on a bending die 25 and the peripheral edge part thereof is subjected to a bend work in 90 deg. with cutting the whole periphery by a punch 28 and bending die 25. The container 12' that said whole periphery of the end face is bent in 90 deg. is located by the pilot device consisting of a pilot claw 34, spring 35 and spring stopper 37 being fitted to a die set 38 on the hemming stand 40 which is provided on a slope face 40b and subjected to a hemming preparatory bend work with bending about 45 deg. to the inner side by pressing the end face 12b to said slope 40b by a punch 33. After positioning the container 13' worked with the hemming preparatory bending thus obtd. on a flat hemming stand 41 same as above it is pressed by the punch 33, the end face 12b is made in close contact with bending and a hemming container 14' is obtd.
