    Acute angle bending device
    The present invention relates to a bending device for bending a product, and more particularly, to an acute angle bending device configured to be molded in one step using a reverse bending punch when bending the product at an acute angle.
    In general press processing, when the vertical direction or the processing direction of the product has to be inclined, the cam mechanism is used. The bending method using the cam method is to bend the product inward or to bend the product by changing the direction of the vertical direction. It is supposed to be.
    Meanwhile, in order to bend and mold a plate-shaped product as shown in FIG. 1A at an acute angle as shown in FIG. 1C, a prior work of first bending at 90 ° as shown in FIG. 1B should be performed.
    After that, the product must be bent at an acute angle as shown in FIG.
    However, the bending process as described above is a simple molding process, but in the case of the work of the composite molded product, since the working process of the mold must be divided into several processes in addition to the two bending molding processes as described above, the number of working processes is increased. Of course, it takes a lot of work.
    In addition, in the above-described acute angle bending molding, since the 90 ° bending molding must be preceded as a preliminary step of the acute angle bending of the product, two presses are required along with a separate mold production.
    The present invention is intended to solve the above problems, the mold manufacturing cost is reduced by configuring a single mold device to be molded in a single process that was conventionally molded in two processes when forming acute angle of the product In addition, the present invention provides an acute angle bending device that can shorten the working process.

The punch guide 80 which guides the vertical movement of the said bending punch 70 at the same time as M raises is provided.
    The components of the present invention installed in the upper mold press 10 and the lower mold 50 are described in more detail as follows.
    First, the bending die 30 is lowered while the acute angle forming portion 30a is first contacted with the upper surface of the product M placed on the upper side of the punch guide 80 and then rotated about the hinge 35 while being lowered. The side surface is formed to uniformly press the upper surface of the product (M), wherein the acute angle forming portion (30a) is formed so that the angle consisting of the side and the lower surface protrudes at an acute angle.
    In addition, the bending die 30 and the support die 40 are formed such that the gap is maintained so that the bending die 30 may be rotated by a predetermined amount by the meme elastic means 45 as shown in FIG. 4. It is preferable.
    Next, the meme-elastic means 45 is a push pin 45a in contact with the upper end of the bending die 30, a compression spring 45b for providing an elastic force to the push pin 45a, and the compression spring It consists of a bolt 45c which supports 45b, and is attached to the hole 10a of the upper press 10 so that the upper end of the side where the acute angle shaping | molding part 30a of the said bending die 30 is located can be pressed.
    Next, the operation cam 60 is provided with a cam guide 66 for guiding the horizontal movement from the upper side, the cam guide 66 is a bending punch 70 between the punch guide 80 The guide surface 66a which guides to move up and down in the diagonal direction is formed.
    Similarly, the punch guide 80 is formed with a guide surface 80a for guiding the up and down movement of the bending punch 70. The punch guide 80 is supported by the fixing pin 85 on the lower mold 50. have.
    The return means 65 of the actuating cam 60 is connected to the rod 65a of an elongated rod-shaped rod 65a fixedly connected to the rear of the actuating cam 60, and the actuating cam 60 is returned to its original position. Consists of a return spring (65b) for providing an elastic force, it is installed in the hole of the return block 55 fixed to the upper side of the lower die (50).
    Next, the bending punch 70 and its return means 75 are inclined by an acute angle with respect to the horizontal direction of the lower mold 50 and the actuating cam 60, and the return means 75 is the bending punch. It consists of a long rod-shaped rod (75a) is fixedly connected to the back of the 70, and a return spring (75b) to provide an elastic force to the rod (75a) so that the bending punch 70 is in place, the lower mold (50) It is installed through the hole 50a of ().
    Looking at the action of the acute angle bending device of the present invention configured as described above are as follows.
    As shown in FIG. 2 and FIG. 3, when the upper die press 10, the driving cam 20, and the bending die 30 are lowered, the operation cam 60 and the bending punch 70 mounted on the lower die 50 are provided. The product (M) placed on the punch guide 80 is in close contact with the acute angle forming portion (30a) of the bending die 30 while bending the product (M).
    That is, when the upper press 10 is lowered, the acute angle forming portion 30a of the bending die 30 first contacts the product M placed on the punch guide 80, and then the bending die 30 is The hinge 35 is rotated about a certain time so that the entire bottom surface is pressed on the upper surface of the product (M).
    In addition, while the driving cam 20 is also lowered simultaneously with the bending die 30, the operation cam 60 is moved in the horizontal direction, and the bending punch 70 is raised by the horizontal movement of the operation cam 60 to raise the product ( The end portion of M) is bent and pushed up to the acute angle forming part 30a, and then closely contacted to the acute angle forming part 30a of the bending die 30 to form the product M at an acute angle. This state is a state shown in FIG.
    Thereafter, when the upper press 10 is raised a certain time, the bending die 30 is acutely rotated in a product formed at an acute angle while being rotated as shown in FIG. 4 by the memeelastic means 45 holding the upper side. After the part 30a is completely disengaged, the upper part 30a moves upward along the upper press 10.
    At the same time, the driving cam 20 also moves upward along the upper die press 10. The driving cam 20 moves upward and the actuating cam 60 and the bending punch 70 are returned to the return means 65,75. Backed by the return.
    Therefore, in the present invention, as described above, the bending punch 70 is raised by the driving cam 20 and the operation cam 60 when the upper press 10 is lowered, thereby forming an acute angle of the bending die 30. It is to be bent to the portion (30a) will be able to be molded at an acute angle.
    As described above, the acute angle bending device of the present invention is configured to mold an acute angle of a product in a single process by using a single mold apparatus, thereby reducing mold manufacturing cost and shortening work process and time. There is an advantage.
