Title: Method for shearing plate material

IPC: B21D28/24
Filed: 1990-04-25
Abstract: PURPOSE:To eliminate the need for removing burrs by determining the size of a punch in a biting stage so as to generate the burrs. CONSTITUTION:The width W2 of the punch 52 in the biting stage is set wider than the width W1 of the square hole 51a of a die and the punch is bitten to the prescribed depth smaller than the plate width to form a thin part 23 on the steel plate 11a. A triangular projection 24 is then formed in a separating stage. The thin part 23 ruptures and generates the burrs. The burr 23a on the body 11 side is generated to face upward and the burr 23b on the projection 24 side faces downward and, therefore, the burrs lay down without projecting to a sharp blade shape toward the outside from the respective surfaces, thus eliminating the danger. Paint completely covers the burrs and the possibility of rust generation is eliminated, if the steel plate is painted. The need for removing the burrs is eliminated and the time for processing is shortened.
