  However, in order to ensure an accurate turning operation of the rotating body that is rotatably supported by the supporting shafts provided on both sides, the supporting shafts must be set at accurate positions on both sides of the rotating body. It is necessary to have a very advanced technique to make a hole to be tightened by driving a conventional spindle having a circular cross section on both sides of the rotating body. After making a hole on one side, it is necessary to make a hole on the other side. It took a lot of time and labor to change the setup, such as positioning and clamping of the workpiece.

  In addition, if the misalignment occurs on the setting spindles on both sides, the rotating body cannot be operated, and the product cannot be realized. Further, it is difficult to insert the support shaft into a cylindrical circular hole bearing set in the base portion and to support the assembly shaft as the workpiece becomes larger.

  Furthermore, with regard to the rotation type in the press mold, there has been developed a type that presses a long work in parallel with the rotation type in parallel, and the support shaft and bearing are set between the adjacent rotation types. It is also necessary to set a shaft support structure without taking up space and to rotate the effective mold part continuously.

  The present invention intends to cope with the above-mentioned problems, and is a method of forming a shaft body having a circular section on one side surface of a mounting portion formed in a rectangular shape and corresponding to the mounting portion provided on the shaft support portion of the rotating body. The support portion is formed by surface fitting the mounting portion to a shape surface portion.

  That is, the support shaft setting position on both sides of the rotating body is determined as an axial line position penetrating from one side to the opposite side, and in order to accurately set the support shaft at that position, the surface mounting with high adhesion and no misalignment is required. In some cases, the support shaft is attached to the rotating body.

  According to surface fitting, unlike the setting of the support shaft by drilling and driving, which is difficult to determine the position of the through-axis line and easily causes positional deviation, the positioning from the upper surface of the rotating body main body without positioning for each setting side surface The through-axis line position can be captured, and a rectangular fitting recess or step is provided to utilize stability by surface contact and position fixing by dip fitting.

  Also, for the bearing, after forming a semicircular groove in which the bearing hole is vertically divided, and fastening the base member for mounting to the main body in which the fastening bolt hole is drilled in a direction perpendicular to the bearing hole, The support member of the rotating body is mounted on the semicircular groove of the mounting member, and the covering member having a covering structure with the mounting base member formed with a semicircular groove facing the semicircular groove is mounted on the mounting base member. The support shaft of the rotating body is pinched so as to be rotatable.

  With this configuration, it is possible to avoid complicated operations such as drilling the shaft hole and inserting the support shaft into the bearing hole, and it is also possible to easily perform the mounting operation of the mounting base member that has been made compact by vertical splitting.

  Furthermore, conventionally, when a long mold is pressed at once by connecting a rotating mold of a molding die, it has been impossible due to the setting space of a support shaft and a bearing between adjacent rotating molds. For the continuous setting that does not create a gap in the joint part of the effective mold part, after the base member for mounting the bearing to the bearing body is fastened to the body bearing part, the effective mold is placed above the setting space for the bearing and bearing Place the pivoting support shaft with the part overhanging on the semicircular groove of the mounting base member, and insert one end of the support cover cover part by the semicircular groove of the covering member into the lower part of the overhanging structure. It is configured to be locked by attaching the support shaft, and the cantilever can be fastened only by the front part where the bolt fastening work is possible, so that the effective mold part can be set continuously without creating a gap in the joint part.

  Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a support shaft member, which is formed with fastening bolt holes 12 and 12 and a positioning pin hole 23 for attaching to the shaft support portion of the rotating body main body A on one side surface of the attachment portion 11 formed in a rectangular parallelepiped shape. A shaft body 13 having a circular cross section is formed on one side surface orthogonal to the bolt hole drilling direction. In addition, you may form the rectangular shape of the attachment part 11 in a triangular parallelepiped and a polygonal rectangular parallelepiped by setting environment.

  Moreover, the attachment part 11 can be attached to the rotating body main body A from any of the front, upper, lower, and rear sides of the rotating body A according to the setting environment by forming it in a rectangular shape.

  That is, as shown in FIG. 3, the support shaft member 1 of the molding die is attached by forming extra recesses 14 on both front sides of the rotating body main body A to form fitting recesses 14 corresponding to the shape of the mounting portion 11. By fitting and fastening the portion 11, it is possible to mount from the front where the work is easy.

  Also, as shown in FIGS. 4 and 5, the insertion recesses 14 are formed on both lower sides of the rotating body main body A (1A, 2A), and the attachment portion 11 is inserted and tightened from below, so that the overhang portion 15 It is possible to cope with the case where the fastening wrench cannot be operated from above due to the presence, and it is possible to continuously set the effective mold portion by the overhang portion 15.

  Furthermore, as shown in FIG. 6, insertion concave portions 14 are formed on both sides of the back surface of the rotating body main body A, and the attachment portion 11 is inserted and tightened from the back surface, thereby making the most of the front space of the rotating body main body A. It becomes possible.

  Reference numeral 2 denotes a bearing member, which is formed with a semicircular groove 3a in which the bearing hole 3 is vertically divided, and a mounting member 2a to the shaft support body B in which fastening bolt holes 21 and 21 are formed in a direction perpendicular to the groove 3a. A semicircular groove 3b facing the semicircular groove 3a is formed, and includes a covering member 2b having a covering structure with the attachment member 2a.

  Further, on the inner wall surfaces of the semicircular grooves 3a and 3b formed in the mounting member 2a and the covering member 2b, the vertically split bearing pieces 5 that are combined by covering via thrust washers are respectively attached and supported. The rotating shaft 13 is smoothly rotated.

  Further, the fastening bolt hole is provided with an accommodation hole 22 for accommodating the bolt head top portion 41, and when the bolt 4 is tightened, the head top portion 41 is accommodated in the accommodation hole 22 so as not to protrude to the outside. Further, if necessary, a pin hole 23 for positioning is provided.

  Regarding the support shaft member 1 and the bearing member 2 configured as described above, first, the mounting portions 11 of the support shaft member 1 are respectively fitted or surface-joined to the both-side shaft support portions of the rotating body main body A, and tightened by the fastening bolts 4. The support shaft by the shaft body 13 is set to the rotating body main body A by being fixed.

  In this case, since the setting positions of the shaft bodies 13 and 13 are regulated by the mounting portion 11 or the insertion recess 14 indexed and set with the through-axis line L of the rotating body main body A as the axis, There will be no misalignment. Moreover, since the penetration axis L is positioned by the measurement line from the upper surface of the rotating body main body A, accuracy can be expected.

  Next, the mounting member 2a is surface-bonded to the bearing portion of the shaft support body B and fastened and fixed by the fastening bolts 4, and the rotating body main body A is lifted by a crane or the like to fasten and fix the support shafts 13 and 13 of the rotating body. The mounting member 2b, which is fitted and mounted on the semicircular groove 3a of the mounting base member 2a formed, is formed with a semicircular groove 3b opposite to the semicircular groove 3a and has a covering structure with the mounting member. The rotating body main body A is pivotally supported by the pivotal support body B so as to be covered and fixed from above.

  Of course, both the support shaft member and the bearing member according to the present invention need not always be used, and only one of them may be used depending on the setting environment or the like.

  FIG. 5 shows the configuration of the adjacent portion in the case where the effective mold portion has an overhang structure because it is not possible to take a setting space for the support shaft and the bearing between the adjacent rotating die by connecting the rotating die. FIG. 6 is a side view showing an adjacent structure of a rotation-type connecting portion having a cutaway cross-section as a main portion showing a rotation-type with an overhang portion 15 protruding toward the upper portion of a fastening base member 2a. The support shaft 13 is placed on the semicircular groove of the mounting base member, and the front end side of the covering member 2b is inserted into the set space in the lower space to cover and lock the support shaft 13 so that the bolt can be tightened. Cantilever fastening is done only in the front part.

  In other words, the mounting base member 2a of the bearing has a mounting base member 2a from the top due to the presence of the overhanging portion 15 if the rotating support shaft 13 having the overhanging portion 15 is placed on the semicircular groove 3a. Since the operation of the fastening wrench for fastening the covering member 2b cannot be performed, first, the mounting member 2a is surface-bonded to the bearing portion of the shaft support body B and fastened and fixed by the fastening bolt 4, and then the rotating body The support shafts 13 and 13 are placed on the semicircular groove 3a of the mounting base member 2a fastened and fixed, and the distal end side 25 of the covering member 2b is inserted into the lower portion of the overhang portion 15 to cover the support shaft 13. After wearing, it is fastened and fixed by the bolt hole 21 of the seat piece 24 on the front side. The bearing member according to the present invention enables this cantilever structure, and thereby allows the overhang portion 15 to be continuously provided.

  Since the present invention is configured as described above, conventionally, the positioning of the supporting shafts set on both sides of the rotating body, which required a great amount of labor and skill, the drilling of the shaft holes for setting the bearings, and the insertion of the supporting shafts into the bearing holes. This makes it possible to avoid complicated operations such as, and to allow the rotating bodies to be arranged in parallel without generating a disconnection clearance between the rotating bodies connected in series.
