Abstract
PURPOSE: To make possible rolling of a product which differs in the thickness at both ends in a longitudinal direction in rolling by means of rolls with a forming groove, by forming the forming groove and one of forming projecting parts meshing with this to the specific shape which has control forming parts corresponding to the thickness of the product and is longer than the overall length of the product.
CONSTITUTION: A rolling device 1 for a product differing in thickness at both ends in a longitudinal direction, for example, the fork of a fork lift truck, consists of forming rolls 2, 3, with a forming groove 4 and a forming projecting part 5 respectively. The groove 4 is successively changed of its depth according to the length of the product and the change of the thickness in the longitudinal direction of the product. The overall length of the groove 4 is made longer than the overall length of the product, and control forming parts C are provided between the forming start points and end points A, B of mutually differing depths that become both end positions of the product of the groove 4 and these are connected stepless. A heated blank material is inserted in the groove 4 and is rolled, whereby the forming 7 of the constinuous state of the product is obtained. The portions of the control parts C1 connecting the forming start points and end points A1, B1 of mutually different thicknesses stepless are removed to obtain the product.
