Description

  The present invention relates to a die assembly in which a die used for separating individual molded products from a molded product assembly connected in an array is attached to a die fixing substrate so that the vertical and horizontal positions can be adjusted.

  The punching die is used in a state in which individual molded products are arranged vertically and horizontally on a substrate in accordance with a molded product assembly in which individual molded products are arranged and connected, and further fixed to the substrate. However, the dimension between the molded products of the molded product assembly expands and contracts due to the influence of the material mixing ratio, heat, manufacturing environment, and the like. Therefore, even if punching is performed without adjusting the position of each punching die for the state in which the dimension between the molded parts of the molded article assembly is stretched and is not appropriate, there will be a surplus or lack of dimensions in the molded article. . For this reason, the molded product is out of the product standard and must be discarded.

  In order to solve the above-mentioned problems, a device for adjusting the positions of a plurality of die assemblies to which a plurality of die dies are attached is disclosed (Patent Document 1). This is a structure in which a spacing member is sandwiched between a plurality of punching die assemblies and fixed with both screw bolts. As a result, the die assembly can be moved symmetrically and fixed.

  However, since this is performed using a die assembly having a plurality of die dies attached as a unit, it has not been possible to adjust the position of each molded product. In addition, the die assemblies could be moved away from each other, but they could not be moved independently.

Then, in order to enable position adjustment with respect to each molded product, an invention provided with position adjustment fixing means is disclosed (Patent Document 2). This is to fix the punching die to which the punching blade is fixed to the punching die fixing substrate. And a bolt provided to fix the punching die to the punching die fixing substrate, and a mounting hole provided in the punching die and having a diameter larger than the diameter of the bolt, through the mounting hole. It is characterized by being fixed by a washer and a nut.
Accordingly, the punching die can be moved by an amount corresponding to the diameter of the mounting hole larger than that of the bolt, and the position can be finely adjusted.

  However, in such a method, since the movement of the punching die itself is a manual work or the like, it is difficult and time-consuming to achieve a desired adjustment amount.

  Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1

  FIG. 1 is a perspective view showing a die assembly 30 of the present invention. The die assembly 30 is a molded product assembly arrayed and connected to the upper surface of a stainless steel plate-like die-fixing substrate 21 that is larger than the die 20 (see, for example, FIG. 6 of Patent Document 2). A die 20 used for separating individual molded products from the die is attached to a die fixing substrate 21 so that the vertical and horizontal positions can be adjusted with a gap.

  The punching die 20 includes a wooden plate-like main body substrate 5 corresponding to a base portion, a punching blade 4, a position adjusting hole 1, a fixed base plate 2, a cylindrical member 16, a mounting hole 17, a washer 18, and a bolt 19. In the figure, a total of nine punching dies 20 are arranged vertically and horizontally, but the number of punching dies 20 is increased or decreased in accordance with the molded product assembly.

  FIG. 2 is a perspective view of one die 20 of the die assembly 30. Each inner wall 6 of the position adjusting hole 1 is provided in parallel to the vertical and horizontal arrangement directions. Therefore, since each facing inner wall 6 is parallel, the position adjustment hole 1 is configured in a rectangular shape.

  The position adjustment hole 1 is installed near the center of the punching die 20. However, the installation location may be on the main body substrate 5 without the extraction blade 4, and the position can be changed as appropriate.

  The metal fixed base plate 2 is installed inside the position adjustment hole 1 with a predetermined adjustment gap M therebetween. Each outer wall 8 of the fixed base plate 2 is provided so as to be parallel to each inner wall 6 of the position adjusting hole 1. Therefore, the shape of the fixed base plate 2 is rectangular like the shape of the position adjustment hole 1.

  The position of the punching die 20 can be adjusted within the range of the adjustment gap M. That is, the fixed base plate 2 is provided with a through female screw hole 9 provided at a central position with a width that is parallel to one direction of the vertical and horizontal arrangement directions and that is perpendicular to the through direction of the fixed base plate 2. The through-hexagonal bolt body 10 that moves through the through-die thread hole 9 and moves the punching die 20 in the penetration direction when the screw is rotated in the through-hole thread hole 9 is simply provided. By simply rotating the through hexagonal bolt body 10, the position of the die 20 can be adjusted with respect to the fixed base plate 2, that is, the die fixing substrate 21, accurately and easily in one vertical and horizontal direction. .

  FIG. 3A is a cross-sectional view of the through hexagon bolt body 10 provided in the through female screw hole 9 parallel to one direction of the vertical and horizontal arrangement directions, and passing through the center of the through hexagon bolt body 10. 3B shows a state in which the through hexagon bolt body 10 is rotated from the state of FIG. 3A and the punching die 20 has moved to the right side with respect to the fixed base plate 2. FIG. 3A, if the through hexagon bolt body 10 is provided in the longitudinal direction of the arrangement, the through hexagon bolt body 10 is provided in the lateral direction of the arrangement. It becomes sectional drawing which passes along the center of.

  Thus, since the through hexagon bolt body 10 is provided vertically and horizontally, it is possible to individually adjust the position in the through direction of each through hexagon bolt body 10, that is, in the vertical and horizontal arrangement direction of the die assembly 30. .

  FIG. 3A shows a through hexagon bolt body 10 in which a coil spring 11 in a compressed state is fitted to the tip side of a hexagon bolt 10a whose overall length is shorter than the distance L between the inner walls 6 facing the penetration direction. The head of the through hexagon bolt body 10 and the end of the coil spring 11 are in contact with a metal reinforcing plate 13 installed on the inner wall 6. The metal reinforcing plate 13 is not necessarily limited to the U-shape as shown in FIG. 2, and may be a rectangular cylinder installed over the entire inner wall 6 of the position adjusting hole 1.

  In the state of FIG. 3A, the distance between the outer wall 8 of the fixed base plate 2 on the head side of the through hexagon bolt body 10 and the inner wall 6 facing each other is denoted by A. Let B be the distance between the outer wall 8 of the fixed base plate 2 on the front end side of the through hexagon bolt body 10 and the inner wall 6 facing each other. The distance L between the inner walls 6 facing the penetration direction is unchanged. The total length between the end of the coil spring 11 that contacts the inner wall 6 from the head end of the through hexagonal bolt body 10 is the sum of A and the length in the through direction of the fixed base plate 2 that does not change, and is equal to L To do. Further, the head end of the through hexagonal bolt body 10 and the end of the coil spring 11 are in contact with the inner wall 6 facing each other without any gap, and the current state is maintained by the elastic biasing force of the coil spring 11. The current status maintenance function is always active.

  Therefore, when the penetrating hexagon bolt body 10 is rotated and moved in the penetrating direction, the punching die 20 is also moved following that. And by the said present state maintenance function, the head part end of the penetration hexagon bolt body 10, the edge part of the coil spring 11, and the inner wall 6 which opposes each contact | abut without gap, and the penetration female screw hole 9 and the penetration hexagon bolt body 10 are contacted. There is no rattling between them.

  In the state of FIG. 3A, the through hexagon bolt body 10 is rotated to the right by a desired movement amount C. Then, as shown in FIG. 3B, the distance between the outer wall 8 of the fixed base plate 2 on the head end side of the penetrating hexagon bolt body 10 and the inner wall 6 facing each other is AC. The distance between the outer wall 8 of the fixed base plate 2 on the front end side of the through hexagon bolt body 10 and the inner wall 6 facing each other is B + C.

  As a result, the total length between the end of the penetrating hexagonal bolt body 10 that contacts the inner wall 6 of the coil spring 11 from the head end is the sum of the length in the penetrating direction of the fixed base plate 2 that is unchanged and B + C. Yes, you can see that it matches L. Needless to say, even if the through hexagon bolt body 10 is rotated to the left by the desired movement amount C, the same result as described above is obtained only by changing the movement direction.

  From the above, the distance between the end of the penetrating hexagonal bolt body 10 that contacts the inner wall 6 of the coil spring 11 from the head end of the penetrating hexagonal bolt body 10 is the penetrating direction, regardless of which direction the through hexagonal bolt body 10 is rotated and moved in any direction. It can be seen that the distance L matches the distance L between the inner walls 6 facing each other. Furthermore, with the current maintenance function, the head end of the through hexagon bolt body 10 and the end of the coil spring 11 and the inner wall 6 facing each other are in contact with each other without any gap, and between the through female screw hole 9 and the through hexagon bolt body 10. There is no rattling.

  The total length of the hexagonal bolt 10a is shorter than the distance between the inner walls 6 facing in the penetrating direction, and a compressed coil spring 11 is fitted on the tip side to form the penetrating hexagonal bolt body 10. Thereby, the punching die 20 can be firmly fixed and maintained by utilizing the elastic force and expansion / contraction characteristics of the compressed coil spring 11. Moreover, the total length of the hexagon bolt 10a should just be shorter than the distance between the inner walls 6 which face the said penetration direction. Therefore, standard hexagon bolts 10a having various overall lengths can be used, and versatility is high.

  When the through hexagon bolt body 10 is rotated by a desired amount of movement, the position of the die 20 can be easily adjusted by a desired amount of movement with respect to the fixed base plate 2 in the through direction of the through hexagon bolt body 10. Further, the fixed base plate 2 is fixed to the die fixing substrate 21 and serves as a reference for position adjustment. That is, the position can be adjusted in one direction with reference to the fixed base plate 2.

  FIG. 4A shows the fixed base plate 2 provided with scales 14 in the vertical and horizontal arrangement directions. An indicator plate 15 is extended from the front end side of the through hexagon bolt body 10 of the main body substrate 5 of the punching die 20 so as to point to the scale 14. When the punching hexagonal bolt body 10 is rotated to move the punching die 20, the movement distance can be numerically recognized with the indicator plate 15 as a guide, so that the position adjustment becomes easy.

  FIG. 4B shows a state in which the die 20 is fixed to the die fixing substrate 21. The fixing method is not limited to those described below, and may be a known technique. The columnar member 16 is provided with a through female screw hole 9 at the center, and is fixed to the punching die fixing substrate 21 by screwing from the back surface. The attachment hole 17 is provided on the main body substrate 5 of the die 20 and is configured to have a diameter larger than the diameter of the columnar member 16.

  A bolt 19 is screwed into the through female screw hole 9 via a washer 18 larger than the mounting hole 17, and the punching die 20 is fixed to the punching die fixing substrate 21. Since the diameter of the mounting hole 17 is larger than the diameter of the cylindrical member 16, a gap is formed between them. The die 20 can be moved within the gap. The gap and the adjustment gap M in the position adjustment hole 1 are the same size. After the position adjustment, the punching die 20 can be firmly fixed to the punching die fixing substrate 21 in this way so that each punching die 20 does not move during use.

Embodiment 2

  In the punch die assembly 30B of FIG. 5A, a hexagonal bolt 10b having the same length as the distance between the inner walls 6 facing in the penetrating direction is attached as the penetrating hexagonal bolt body 10B. In the first embodiment, there is no difference except that the compressed coil spring 11 is fitted to the distal end side of the hexagon bolt 10a whose overall length is shorter than the distance between the inner walls 6 facing in the penetration direction. Let A be the distance between the outer wall 8 of the fixed base plate 2 on the head side of the through hexagon bolt body 10B and the inner wall 6 facing each other. Let B be the distance between the outer wall 8 of the fixed base plate 2 on the front end side of the through hexagon bolt body 10B and the inner wall 6 facing each other.

  The head and tip of the through hexagon bolt body 10B are in contact with the inner wall 6 with no gap. Therefore, when the through hexagon bolt body 10B is rotated to the right by the desired movement amount C, the punching die 20B naturally slides to the right by the movement amount C. Therefore, as shown in FIG. 5 (b), the distance between the outer wall 8 of the fixed base plate 2 on the head side of the through hexagon bolt body 10B and the inner wall 6 facing each other is AC, and the front end of the through hexagon bolt body 10B. The distance between the outer wall 8 of the fixed base plate 2 on the side and the inner wall 6 facing each other is B + C.

  Although not shown, when the through hexagon bolt body 10B is rotated to the left by the desired movement amount C, the punching die 20B naturally slides to the left by the movement amount C.

  By using the hexagon bolt 10b having the same length as the distance between the inner walls 6 facing each other in the penetrating direction, the number of components is reduced, the cost is low, and the assembly is easy as compared with the case where the coil spring 11 is used. Further, since the head end and tip of the penetrating hexagonal bolt body 10B and the inner wall 6 facing each other are in contact with each other without a gap, the position can be accurately adjusted without rattling in the penetrating direction.

Embodiment 3

  In the die assembly 30C of FIG. 6 (a), the nut 12 is screwed and fixed so that the end surface is in contact with the inner wall 6 toward the tip side of the hexagon bolt 10c whose overall length is shorter than the distance between the inner walls 6 facing in the penetrating direction. Through-hole hexagon bolt body 10C. The entire length of the through hexagonal bolt body 10 </ b> C is equal to the distance between the inner walls 6 facing the penetrating direction of the position adjusting hole 1.

  The method of fixing the nut 12 to the through hexagon bolt body 10C is not limited to the one described below, and may be a known technique. A through hole 12a penetrating the nut 12 and the hexagon bolt 10c is opened from a direction orthogonal to the penetrating direction. If the spring pin 12b is inserted there, a strong fixing force is generated by the action of the spring pin 12b that attempts to widen the through hole 12a from the inside.

  In the die assembly 30D of FIG. 6B, the nut 12 is screwed to the tip side of the hexagonal bolt 10d whose overall length is shorter than the distance between the inner walls 6 facing in the penetrating direction, and the nut 12 is further adjacent. Are screwed and fixed to form a through hexagon bolt body 10D. The entire length of the penetrating hexagon bolt body 10D is equal to the distance between the inner walls 6 facing the penetrating direction of the position adjusting hole 1.

  The method of fixing the nut 12 to the through hexagon bolt body 10D is not limited to the method described below, and may be a known technique. The first nut 12 and the second nut 12 are adjacent to each other and rotated in opposite directions to be firmly fixed. Further, if an adhesive such as an instantaneous adhesive is attached to the adjacent surface, the fixing can be further strengthened.

  In the punch die assemblies 30C and 30D, the contact area with the end face of the nut 12 can be increased by applying the end face of the nut 12 to the contact portion with the inner wall 6 on the front end side of the through hexagon bolt bodies 10C and 10D. The die 20C, 20D can be firmly fixed to the die fixing substrate 21. Further, by moving the position of the nut 12 with respect to the through hexagon bolt bodies 10C and 10D, the inner wall facing the entire length of the through hexagon bolt bodies 10C and 10D in the through direction of the position adjusting hole 1 regardless of the total length of the hexagon bolts 10c and 10d. The distance between the six can be matched. Therefore, standard hexagon bolts 10c and 10d having various overall lengths can be used, and versatility is high.

  The technical features common to the above-described embodiments are summarized as follows. The die assemblies 30, 30B to 30D of the present invention are used to separate individual molded products from the arrayed molded product assemblies. 20, 20B to 20D are attached to the die fixing substrate 21 so that the vertical and horizontal positions can be adjusted. Therefore, the positions of the punching dies 20, 20B to 20D can be adjusted individually.

  The fixed base plate 2 is provided in a place where the punching blades 4 of the main body substrate 5 for fixing the punching blades 4 of the punching dies 20, 20 </ b> B to 20 </ b> D are not provided, and the position adjusting holes 1 parallel to the inner walls 6 in the vertical and horizontal arrangement directions. In the position adjusting hole 1, the die is fixed to the die fixing substrate 21 with a predetermined adjusting gap M therebetween.
