Title: Pressing device for full circumference bending
Inventor: TAKESHITA AKIRA
IPC: B21D19/08
Filed: 1979-12-28
Abstract: PURPOSE: To enable working with one unit of a die and one process by cooperating the stationary die of the stationary lower die, the 1st, 2nd movable punches and the stationary die of a male die by means of cams at the time of forming the bent parts of a U shape to one side and an L shape to the remaining side.  
     CONSTITUTION: In order to obtain a product P, the preliminary bent part a 1  for a U shape of the work W is placed on the 1st stationary die 4, and a male die 1 is moved downward. Then, while the 2nd cam driver 40 is sliding to the right, it moves a cam plate 16 forward to the right and elevating cams 26, 31 meet slidingly, causing the 2nd movable punch 25 to move upward. Then, the work W is pressed onto the die 4 and punch 25 by a pad 37, and the work is now ready to work. The succeeding downward movement of the male die 1 causes the 1st cam driver 34 to move the punch 6 forward, thereby subjecting the bent part a 1  to U-bending in cooperation with the die 4. Also, the preliminarily bent part b 0  is bent to an L shape by the cooperation of the die 39 and punch 25. After the working the upward movement of the male die 1 causes the drivers 34, 40 to move upward, then the punch 6 is retreated, the plate 16 is moved backward and the punch 25 is lowered by the force of springs, and these go out from the product P.

Title: Manufacture of sheet metal for cr stainless steel
Inventor: MINAMINO SHIGERU
IPC: C22C38/00
Filed: 1986-07-21
Abstract: PURPOSE:To manufacture a sheet metal of Cr stainless steel in high efficiency, by respectively specifying the winding conditions of a hot-rolled steel strip containing specific amounts of Cr and the conditions of scarfing of a decarburized layer by means of pickling. CONSTITUTION:The winding temp., at the length- and width-direction central part, of the hot-rolled steel strip containing 5-18% Cr as principal alloying element is regulated to 800-600 deg.C. Further, the amount of cooling water is controlled by the use of a run-out table so that temps. are also higher at both ends than at the central part by about 50 deg.C. In this way, the progress of softening or tempering of the whole coil due to recuperating during and after winding the steel strip is uniformized and the necessity of the annealing stage of hot-rolled plate can be obviated. Subsequently, descaling is carried out by the use of a pickling solution containing sulfuric acid or hydrochloric acid as principal component to subject the steel-strip surface to scarfing by >=10mu per one side, so that coil grinding stage can be omitted or simplified. In this way, high-efficiency manufacture of stainless-steel sheet metal can be carried out by the tandem cold rolling process by the use of large-diameter rolls.
