Claims

[Claims for Utility Model Registration] (1) Parallel shafts are provided that are driven to rotate synchronously by appropriate means, and one or more male collars and female collars are inserted into each shaft and placed at respective set positions. opposite,
On the other hand, one or more adjustment collars with different wall thickness dimensions are prepared, and the setting positions of the male collar and female collar are set by the combined dimensions of the one or more adjustment collars fitted onto each shaft. The roll type is composed of a male roll and a female roll relative to each other, and the sheet metal is fed and passed between the male and female rolls, and the sheet metal is drawn by the male and female collars. Sheet metal drawing machine. (2) Male and female collars and adjustment collars are ring-shaped with a central hole into which the shaft is inserted tightly.Adjustment collars are available with various wall thicknesses, but as a general rule, they are formed with the same outer diameter. However, the male collar is formed to have a larger diameter than the adjustment collar by the processing dimensions (depth, step), and the wall thickness is formed to match the processing dimensions (width), and the female collar is the same as the processing dimensions (width) of the male collar. 2. The roll type sheet metal according to claim 1, wherein the roll type sheet metal is formed to have a smaller diameter by an amount (depth, step), and a wall thickness that is twice the thickness of the male collar + the thickness of the sheet metal. Drawing machine. (3) Male and female type rolls are constructed by inserting and installing male and female type collars at set positions of parallel shafts, and setting the set positions by fitting and inserting adjustment collars in combination. In addition, the positions of the male and female collars on the female and male rolls correspond to the drawing positions on the sheet metal, and the sheet metal is drawn with the female and male rolls. The drawing process is mainly a linear drawing process on a planar sheet metal, such as string drawing, step forming, step bending process, etc. A roll type sheet metal drawing machine according to claim 1.
