The shape may be determined as appropriate so as to be in contact with no gap.

  The die hole 16 is a circular through hole, but is not limited to this. The size and shape of the die hole 16 are determined in accordance with the shape of the flange 74 formed in the punch 52 and the molded product 73.

  The inclined portion 17 is provided by inclining both ends of the sliding surface 14 opposite to the inclined portion 27 of the slider 21 to be described later.

  The escape portion 18 is provided with an inclined portion 17 so that a guide portion 24 and a pressure receiving portion 26 of the slider 21 which will be described later are fitted so that the slider 21 does not interfere with the receiver 11 when the slider 21 enters between the receivers 11. Further, both ends of the sliding surface 14 are dug out.

  The slider 21 has a flat plate shape, and is disposed on the die plate 51 so as to face each other with the receiving member 11 interposed therebetween so that the two sliders 21 can enter the receiving member 11 from both sides. Further, the slider 21 has a first sliding surface 22 on the front side and a second sliding surface 23 on the back side, and the first sliding surface 22 and the second sliding surface 21 when the slider 21 enters between the holders 11. The sliding surfaces 23 are arranged so as to be in contact with the sliding surface 14 of one of the receivers 11 without a gap. Since the material of the slider 21 is the same as the material of the receiver 11, the description thereof is omitted.

  In the die 1 of the present embodiment, the thickness of the slider 21 matches the total amount of movement of the two receivers 11, that is, the amount of change in the thickness of the portion of the die 1 that receives the molded product 71. Therefore, the thickness of the slider 21 needs to be equal to or greater than the sum of the heights of the two flanges 74 formed on the molded product 73 so that the molded product 73 after burring can be taken out.

  The slider 21 is configured to be movable using, for example, a spring or a cylinder (not shown), and the first slide surface 22 and the second slide surface 23 are retracted from between the receivers 11 and the slide surface of the receiver 11. The first sliding surface 22 and the second sliding surface 23 are in contact with the sliding surface 14 of the receiving device 11 and the center of the receiving device 11. Then, the two sliders 21 slide and move to the machining position where they are in contact with each other.

  In addition, the slider 21 includes a guide portion 24 that is hollowed out in a semicircular shape and an inclined portion 27 that is a guide means to be drawn into the inclined portion 17 of the receiver 11 on the surface facing the other slider 21. .

  The guide part 24 has the same diameter as the die hole 16 of the receiver 11 and forms a circular die hole 25 by the mutual contact of the guide parts 24 when the two sliders 21 move to the processing position. .

  The center of the die hole 25 of the slider 21 overlaps with and communicates with the center of the die hole 16 of the holder 11. A punch 52 is fitted into the die hole 25 of the slider 21 during burring. Further, the flange 74 of the molded product 73 may be fitted into the die hole 25 of the slider 21, but in this case, when the slider 21 is moved to the standby position, the flange 74 of the molded product 73 becomes the die of the holder 11. It is necessary to determine the thickness of the slider 21 so as to be out of the hole 16. When the punch 52 and the flange 74 of the molded product 73 are not fitted into the die hole 25 of the slider 21, the die hole 25 (guide portion 24) may not be provided in the slider 21.

  The inclined portion 27 is provided on the surface to be formed except at least the guide portion 24 and the pressure receiving portion 26 that is secured on both sides of the guide portion 24 during burring. The inclined portion 27 is inverted V-shaped with respect to the approach direction so as to be inclined to both the first sliding surface 22 and the second sliding surface 23 so as to be attracted to the inclined portion 17 of the opposing receiver 11. Provided.

  The guide block 31 is an L-shaped block that is inverted up and down, and includes two bolt holes 32 through which the bolts 53 are inserted, and two guide blocks 31 are installed on one receiver 11. The guide block 31 sandwiches the base portion 12 of the receiver 11 with the die plate 51, sandwiches both side surfaces of the base portion 12 in the direction orthogonal to the traveling direction of the receiver 11 with the two guide blocks 31, and the die plate 51 with bolts 53. Fixed to. Since the material of the guide block 31 is the same as the material of the receiver 11, the description thereof is omitted.

  The die plate 51 is provided with eight female screws 54 to which the bolts 53 are screwed. In addition, what is necessary is just to use what is used with the well-known press die for the die plate 51 and the punch 52. FIG.

  Next, the operation | movement at the time of giving a burring process to the to-be-molded product 71 using the die | dye 1 of this embodiment is demonstrated. When the workpiece 71 is placed on the die 1, the slider 21 is moved from the standby position to the machining position. When the slider 21 moves from the standby position (FIGS. 4 and 8A) to the machining position, the inclined portion 27 of the slider 21 is drawn into the inclined portion 17 of the support 11 and the slider 21 is between the support 11. (FIGS. 5, 6, and 8B).

  When the slider 21 moves to the processing position, the first sliding surface 22 and the second sliding surface 23 of the slider 21 are in contact with the sliding surface 14 of the receiving device 11 without any gap, and the two receiving devices 11 are pushed into the slider 21. Then, each of them retracts toward the guide block 31, and the distance between the two receiving tools 11 (receiving surface 15) increases by the thickness of the slider 21 (FIGS. 7 and 9A). In addition, since the force is always applied to the two receivers 11 in the direction in which the distance between each other is reduced, the sliding surface 14 moves to the first sliding surface 22 and the second sliding surface when the slider 21 enters. It contacts the moving surface 23 without a gap.

  In this state, when the product 71 is placed on the die 1 so that the center of the pilot hole 72 is coaxially aligned with the center of the die hole 16, both inner surfaces of the product 71 facing in the short direction are receiving parts. 11 is in contact with the receiving surface 15 without a gap, and the product 71 is held by the die 1 (FIG. 9B, FIG. 10A).

  Burring is performed in a state where the molded product 71 is held by the die 1, and a flange 74 is formed in the prepared hole 72 (FIGS. 10B and 11). The molded product 73 after the burring process cannot be taken out as it is because the flange 74 is fitted in the die hole 16, but when the slider 21 is moved to the standby position, the sliding surfaces 14 of the two receivers 11 are moved. The receiver 11 moves forward until they are in contact with each other without any gap, the flange 74 is removed from the die hole 16, and the molded product 73 can be taken out (FIG. 12).

  As described above, the die 1 according to the present embodiment has a simple configuration, and even when processing such that a part of the molded product 73 fits into the die hole 16 after processing is performed, the slider 21 is simply moved. Thus, the molded product 73 can be taken out, and the cost of the press die and the press device can be reduced, the size can be reduced, and the molding cycle can be shortened. For this reason, the molded product processed using the dice | dies of this invention can be manufactured at low cost.

  In addition, since the sliding surfaces 14 of the two receiving tools 11 are formed in parallel to each other, the receiving tool 11 can move until the sliding surfaces 14 contact each other without any gap. It is possible to increase the amount of change in the thickness of the portion that receives the molded product 71 to the limit of the amount of movement of the receiving tool 11, and for example, there is a range of height in which the flange 74 can be formed (removed) in burring. Spread and flexible. The same effect can be obtained not only for the burring process but also for a molded product that is processed so that a part of the press process is fitted into the die hole.

  In addition, the die 1 of the present embodiment has a structure in which the receiving surface 15 of the receiving tool 11 that is in contact with the molded product 71 when holding the molded product 71 and serves as a pressure receiving surface during burring is integrally formed and is not divided. No pressure-receiving surface deviation occurs during burring. If a structure is adopted in which the pressure receiving surface is divided so that the molded product 73 after burring can be taken out, the pressure receiving surface is displaced during burring, and the periphery of the pilot hole 72 is excessively bent and deformed. Although there is a risk of forming defects such as the roundness not being satisfied, by using the die 1 of the present embodiment, this is prevented, and a molded product 73 without distortion or deformation around the pilot hole 72 is obtained. be able to.

  In the die 2 of the present embodiment, for example, a flange 74 is provided in one prepared hole 72 provided on one side of the surface facing the short direction of a molded product (not shown) that is a long material having a U-shaped cross section. While performing the burring process to form, while holding a to-be-molded product, the molded product 75 after a process can be taken out easily. In addition, a to-be-molded product is an example, and is not limited to this.

  The die 2 according to the present embodiment includes one receiver 11, one fixed receiver 81 that is fixed on the die plate 51 and receives a molded product, supports the receiver 11 during burring, and receives after burring. In order to move the tool 11, the slider 11 includes two sliders 82 that enter and exit from both sides between the receiver 11 and the fixed receiver 81, and two guide blocks 31 that serve as guides when the receiver 11 moves. .

  At the time of burring, the slider 82 enters and is sandwiched between the receiver 11 and the fixed receiver 81, and the molded product is held in a state where the receiver 11, the fixed receiver 81, and the slider 82 are overlapped in three stages. After the burring process, the slider 82 is retracted from between the receiver 11 and the fixed receiver 81, and the receiver 11 and the fixed receiver 81 come into contact with each other. And the fixed receiving member 81 are reduced in distance from each other so that the molded product 75 can be taken out.

  The fixed receiver 81 is an L-shaped block having a base portion 12 placed on the upper surface of the die plate 51 and a receiving portion 83 that is formed perpendicularly from one end of the base portion 12 and receives a product to be molded. The base portion 12 is fixed to the die plate 51 with bolts (not shown) or the like so that 83 faces the receiving portion 13 of the receiving tool 11. Since the material of the fixed receiver 81 is the same as the material of the receiver 11, the description thereof is omitted. Further, the width, height, and thickness of the receiving portion 83 of the fixed receiving member 81 are determined in the same manner as the receiving member 11.

  The receiving portion 83 includes a sliding surface 14 that faces the slider 82 in parallel with the sliding surface 14 of the receiver 11, and a receiving surface 15 that contacts the product to be molded on the back side of the sliding surface 14. The inclined portion 17 and the escape portion 18 are not provided.

  The basic configuration of the slider 82 is the same as that of the slider 21 of the die 1 of the first embodiment, but the inclined portion 84 is not V-shaped, and the first sliding surface 22 is in contact with the sliding surface 14 of the support 11. It is provided so as to incline only toward.

  The operation of the dice 2 of the present embodiment is basically the same as that of the dice 1 of the first embodiment, and a description thereof will be omitted. In the die 2 of the present embodiment, the thickness of the slider 82 is the amount of movement of the receiver 11, that is, the amount of change in the thickness of the portion of the die 2 that receives the molded product.

  There may be one receiver 11 that can be moved in the dice of the present invention like the dice 2 of the present embodiment. Further, if the receiving device 11 is formed in parallel with the surface on which the sliding surfaces 14 face each other, there is no gap between the surfaces on which the sliding surfaces 14 face each other when the slider 82 (21) is in the standby position. It is possible to touch and is not limited to one or two, but may be three or more.
