Title: Method and device for form rolling of tube
Inventor: NAKAMURA KATSUAKI
IPC: B21H3/04
Filed: 1991-01-25
Abstract: PURPOSE:To execute the thread form rolling without deteriorating the form rolling accuracy even in the case of a thin tube by executing the form rolling by setting a relative working speed to a high speed until a bite of a working die to a material to be worked reaches prescribed depth, and thereafter, setting it to a low speed. CONSTITUTION:A relative working speed is determined by a driving speed of a working die and a rotating speed of the working die. The rotating speed of the working die is set to a constant value in advance, and in the beginning of form rolling, working is executed by increasing the driving speed of the working die to V1, and from on the way, form rolling is executed by decreasing the driving speed of the working die to V2. From on the way, the relative working speed becomes low, force in the radial direction of the working die becomes small, and a deformation of a material to be worked can be suppressed. In such a way, thread rolling can be executed without deteriorating the form rolling accuracy even in the case of a thin tube.

Abstract: PROBLEM TO BE SOLVED: To obtain a printer having a function for printing an error indication character in which finding of the error indication character is facilitated by printing the error indication character while reversing white and black as compared with other characters upon occurrence of an error during print processing. SOLUTION: During print processing, a CPU 1 makes a decision whether parity error or overrun error has occurred in 1 byte of a command or data received by an I/F 5, for example. If an error has occurred, a decision is made at section 7 whether white/black reversal is invalid or not and if it is invalid, a white/black reversal setting section is set with a command for making white/ black reversal only of an error indicating character valid. An error part is replaced by an error indicating character print data and stored in a receiving butter 4 and then printing is performed by means of a print data 11 according to a print data including the error indicating character.
