摘要： PROBLEM TO BE SOLVED: To provide a method of producing a different thickness steel plate without using welding and performing complicated roll gap control.SOLUTION: The method of producing a different thickness steel plate comprises: a roll forming step of gradually performing bend-forming on a steel strip with rolls for forming arranged in many steps while sending the steel strip continually, thereby forming a nearly circular cross-section material having a nearly circular cross-section; a step of conveying the nearly circular cross-section material to a device for forming different thickness composed of a fixed die and a mandrel having a diameter different in a longitudinal direction without welding the end of the nearly circular cross-section material; a step of forming different thickness in the longitudinal direction of the nearly circular cross-section material by removing and inserting the mandrel inside the fixed die; and an unbending-forming step of relieving the bending added to the material in the roll forming step, in order to relieve the bending of the nearly circular cross-section material to thereby form a steel strip.

摘要： PROBLEM TO BE SOLVED: To provide a method for continuously drawing a long product capable of a plurality of kinds of drawing in a smaller area than usual by a series of automation, and enabling easy control of the distance between the edge of a plug and the outlet of a dice, and its device. SOLUTION: A dice retention member 14 on which a plurality of kinds of dices 18a, 18b are installed is held movable at the center of an area for reciprocating a long product 20. When the long product 20 is moved from one side to an opposite side making the dice retention member 14 as a center, the long product is put not through the dice but through a piercing space 16 for a long product having a large diameter. Meanwhile when the long product 20 is moved from the opposite side to the one side in reverse making the dice retention member 14 as a center, the long product 20 is put through one dice selected out of the plurality of kinds of dices 18a, 18b. The long product 20 is reciprocated several times from the one side to the opposite side of the dice retention member 14, and every time the long product is put through a dice, the kind of dice is changed by moving the dice retention member 14.

摘要： PROBLEM TO BE SOLVED: To provide a drawing/reducing method of a metallic tube on which thickness deviation is not generated. SOLUTION: The positioning of a floating plug 2 in the metallic tube 1 is executed by forming the outside diameter reducing part on the metallic tube 1 and, based on the positioning, the inside diameter of a aligning hole 11a of a guide die 11 is set to a size which is equal to or approximate to the outside diameter of the metallic tube 1. As a result, because the run-out of the floating plug 2 and metallic tube 1 introduced into a drawing die 9 are prevented, thickness deviation is not generated in the thickness t2 of the reduced metallic tube 1a.

摘要： PROBLEM TO BE SOLVED: To draw a thin wall tube without generating breaking of a tube stock and to improve yield by taking the length of a guide member in the vicinity of the inlet side of a working die as specified times of the outside diameter of the tube stock. SOLUTION: By mounting and arranging a cylindrical guide member 50 in a mandrel 3 part in the vicinity of a plug 2 so as to be situated in the vicinity of the inlet side of the working die 4, drawing of the tube stock 1 is executed. The cylindrical guide member 50 whose length L is three or more times as long as the outside diameter D of the tube stock, whose outside diameter is formed slightly smaller than the inside diameter of the tube stock 1 and radius of curvature chamfering is applied to both ends. In this way, even when thin wall products which have the ratio t/D of thickness (t) to the outside diameter D of

摘要： PROBLEM TO BE SOLVED: To prevent a plug rod from deflecting while progressing drawing by sequentially detaching plural rod receiving members one by one from a clamp carriage every time a tube stock is drawn by a prescribed length. SOLUTION: A plug 10 is set in the inside of stock tube 4, the tip end part of tube stock 4 is chucked with a chuck 6b and is pulled to left direction through a die 6. The rear end part of tube stock 4 is held with a clamp 50. Plural rod receiving members 7 are arranged at back of a clamp carriage 5. When drawing of tube stock 4 is started, the clamp carriage 5 is run in the drawing direction. A pulling member 8 arranged to the carriage 5 moves the receiving member 7 through a projecting part 74 of receiving member 7. When a follower cam member 81 of pulling member 8 is brought into contact with a cam member 9, the pulling member 8 is turned to be displaced upward. A hook part 80 of pulling member 8 is disengaged from the projecting part 74 of receiving member 7. Thus, the receiving member 7 is detached from the carriage 5 and supports a rod 1 at this position.
