Field of the Invention The present invention relates to a method for processing a plate-shaped bent part formed by stamping a metal plate base material. 2. Description of the Related Art As is well known, when manufacturing a large number of plate-shaped bent parts, aluminum, stainless steel, brass, and the like are placed on an NC indexing table whose position can be accurately determined.
After positioning a blank of a metal plate such as copper and moving the punching die at a constant pitch, punching an intermediate material plate into the metal plate base material and separating the intermediate material plate from the peripheral frame, The intermediate material plate is bent at a constant angle along the bending line. [0003] That is, FIG. 6 shows the completed plate bending part A, the workpiece A bending brass of the same plate, fold line X with respect to the main body portion a 1 of a rectangular plate shape, the Y and a mounting portion a 2 and the side wall portions a 3 which is at right angles bent along.
FIG. 7 shows a blank blank B for punching an intermediate material plate A 1 for the plate-shaped bent part A, and the intermediate material plate A 1 is partially connected to a peripheral frame C by a plurality of wire joints D. Is punched by a punching die on the surface of the base material blank A. Therefore, after punching out the plate-shaped bent part A, the wire joint D is cut off using a nipper or the like, removed from the peripheral frame C, and bent along bending lines X and Y by a bending machine. Will be completed. [0004] However, according to such a method of processing the plate-shaped bent part A, the mounting part a 2
Alternatively, when the side wall portion a 3 is bent with respect to the main body portion a 1 , as shown in FIG. 8, the side wall portion a 3 protrudes outward from the outer shape line toward the inner side of the bending corresponding to both ends of the bending lines X and Y. A fold Z is formed, and the fold Z may hit an adjacent mounting part (not shown) or the like, and may cause an assembly obstacle or a surface scratch. In addition, there is also a problem that the cut surface of the wire joint D requires a finishing step, and it is difficult to reduce the cost. SUMMARY OF THE INVENTION In view of the above-described conventional position problems, the object of the present invention is to omit the step of finishing the cut surface of the wire joint portion and to provide the above-described folding at the bent portion of the plate-shaped bent part. An object of the present invention is to provide a method for processing a plate-shaped bent part which does not cause bending sag. In order to achieve this object, the present invention provides an intermediate material plate partially joined to a peripheral frame by a plurality of wire joints on a surface of a base material blank. In a method of processing a plate-shaped bent part, which is performed by punching and bending an intermediate material plate separated from the peripheral frame at a predetermined angle along a bending line, the position corresponding to the bending line of each of the plate-shaped bent parts And the peripheral frame are joined by a bent portion wire joint, and a bent portion punched hole is formed facing these bent portion wire joints, and a length of a corresponding side of the bent portion punched hole is correspondingly bent. The present invention proposes a method of processing a plate-shaped bent part in which the width of the bent part is smaller than the width of the wire joint and a portion from the outline of the plate-shaped bent part to both sides of the bent part punched hole is cut. Things. An embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 shows a plate-shaped bent part 1 completed by the processing method of the present invention.
Is similar to the above-described conventional case in that a mounting portion 1b and a side wall portion 1c are formed by bending a rectangular plate-shaped main body portion 1a at right angles along bending lines X and Y. A feature of the plate-shaped bent part 1 obtained in the present invention is a bent part punched hole 2A formed at both ends of the bending lines X and Y. As can be understood from FIG. The bent hanging Z is to be projected into the bent portion punched hole 2A described in detail later. FIGS. 3 to 5 show a base blank 4 of an intermediate material plate 3 for obtaining the same plate-shaped bent part 1. The intermediate material plate 3 has a plurality of wires each having a joint punched hole 2. FIG. It is supported on the peripheral frame 6 by the joint 5. That is, as shown in FIG. 4, the corresponding side 2a of each joint punched hole 2 is opposed to the corresponding wire joint 5, and the corresponding side 2a of these joint punched holes 2 is provided.
The length L 1 is smaller than the width L 2 of the corresponding wire joint 5, and the corresponding side 2 a of the punched hole 2 of the joint portion is formed into a plate-like bent shape rather than the outline 1 d of the plate-shaped bent part 1. It is located at a position close to the inside of the part 1. In the present invention, the bending lines X and Y
Although the intermediate material plate 3 and the peripheral frame 6 are connected by the bent wire joint 5A positioned above,
These bent portion wire joints 5A are also provided with bent portion punched holes 2A. That is, as can be understood from FIG. 5, like the relationship between the wire joint 5 and joint perforations 3 described above, the length L 1 of the corresponding side 2a of the bent portion perforations 2A is bent corresponding together are a size smaller than the width L 2 parts wire joint 5A, inside the corresponding edge 2a is plate-shaped bending the outline 1d of the plate-shaped bent part 1 of the workpiece 1 the bent portion punched hole 2A It is located in a close position. Since the method of processing the plate-shaped bent part 1 according to the illustrated embodiment has the above-described configuration, the wire joint 5 and the bent part wire joint 5A have a certain width and a large strength. Even if there is, a predetermined outer shape can be obtained only by diagonally cutting with a nipper or the like, so that the supporting strength of the intermediate material plate 3 with respect to the peripheral frame 6 can be enhanced. The oblique cutting of the wire joint 5 and the bent portion wire joint 5A by a nipper or the like eliminates foreign matter protruding outside the outline of the plate-shaped bent part, so that special finishing is not required. After the intermediate material plate 3 is detached from the peripheral frame, it is bent at a right angle by a bending machine or the like along the bending lines X and Y. Are provided with bent portion punched holes 2A, respectively, so that bending droop Z at both ends of each bending line X, Y
Is, as shown in FIG. 2, a corresponding bent portion punched hole 2A.
Will be located inside. As a result, the bent sag Z is prevented from protruding out of the outline of the plate-shaped bent part 1, and the protrusion of the bent sag Z assembles with another part or damages the surface of the other part. Can be prevented beforehand. As is apparent from the above description, according to the present invention, since a bent portion wire joint and a bent portion punching hole are provided in a bent portion of a plate-shaped bent component, finishing processing is performed. The product can be provided without any projections such as bending and sagging at the bent portion without any need for any.
