Description

  The present invention relates to a mechanical press device that reciprocates a movable member using a crank mechanism, and more particularly to a bidirectionally operated mechanical press device.

  Generally, a mechanical press device that performs press processing by reciprocating a movable member by a crank mechanism is configured to convert the energy of circular motion by the crank mechanism into linear motion and use it as thrust (for example, Patent Documents). 1).

By the way, in the press working using the crank mechanism, as shown in FIG. 10, in the circular motion, only a quarter portion (shaded portion E) from 90 ° to 180 ° out of 360 ° is used as the applied pressure. Therefore, only one pressurization (processing) can be performed while the movable member is reciprocated once by the crank mechanism. Therefore, the conventional mechanical press device has a problem that the energy of the circular motion of the crank mechanism is not efficiently used as the applied pressure.

  The operation of the bidirectionally operated mechanical press device 10 configured as described above will be described. First, in the bidirectionally operated mechanical press device 10 shown in FIGS. 1 and 5, the crankshaft 21 of the crank mechanism portion 20 is located in the vicinity of 90 ° of the circular motion (see FIG. 9), and the movable member 30 is moved to the machine base 11. The first fixed side member 40 and the second fixed side member 50 are configured to be positioned at substantially the midpoint. Further, the first fixed pressure member 46 is located on the back side in the cylinder device 45 so that the first fixed side pressure member 46 is flush with the upper surface of the first fixed side molding portion 41, and the second fixed side The second pressure piston 57 is positioned on the forward side in the cylinder device 55 so that the pressure member 56 is flush with the lower surface of the second fixed-side molded portion 51.

It is placed on the upper surface of the side pressure member 76.

  Next, when the crankshaft 21 of the crank mechanism section 20 operates from about 90 ° to about 180 ° of circular motion (see the hatched portion A in FIG. 9), the operation of the crankshaft 21 is performed as shown in FIGS. Along with this, the crank arm 22 moves forward to move the movable member 30 forward to the first fixed member 40 side. In that case, with respect to the 1st workpiece M1 mounted in the upper surface of the 1st fixed side shaping | molding part 41 and the 1st fixed side pressure member 46, the 1st movable side shaping | molding part 60 and the 1st movable side pressure member When the first movable-side molded part 60 presses the first workpiece M1 as the movable member 30 advances, the first fixed-side pressure member 46 holds the first workpiece M1. While moving forward, the first movable pressure member 66 moves backward while pressing the first workpiece M1 in conjunction with the operation of the first fixed pressure member 46. Then, when the crank arm 22 reaches the forward movement position (around 180 ° of the circular motion), the first fixed-side molding part 41 and the first movable-side molding part 60 are joined together, and the first workpiece M1 is formed. Processed. In addition, when the first movable side pressure member 66 moves backward, the second movable side pressure member 76 formed integrally with the movable side pressure piston 67 is interlocked with the upper surface of the second movable side molding portion 70. Retreat to be flush.

  Subsequently, when the crankshaft 21 of the crank mechanism section 20 is operated from about 180 ° to about 270 ° of circular motion (see blank portion B in FIG. 9), as shown in FIGS. With the operation, the crank arm 22 is retracted, and the movable member 30 is retracted to a substantially middle point between the first fixed side member 40 and the second fixed side member 50 of the machine base 11.

  Further, when the crankshaft 21 of the crank mechanism section 20 operates from about 270 ° to about 360 ° of circular motion (see the hatched portion C in FIG. 9), the operation of the crankshaft 21 is performed as shown in FIGS. As a result, the crank arm 22 is retracted, and the movable member 30 is retracted toward the second fixed member 50. At that time, the second fixed side molding portion 50 and the second fixed side pressure member in a state where the second workpiece M2 is placed on the upper surfaces of the second movable side molding portion 70 and the second movable side pressure member 76. When the second movable side molding part 70 presses the second workpiece M2 as the movable member 30 moves backward, the second fixed side pressure member 56 holds the second workpiece M2. The second movable side pressure member 76 moves forward while pressing the first workpiece M2 in conjunction with the operation of the second fixed side pressure member 56 while moving backward. Then, when the crank arm 22 reaches the retracted position (around 360 ° of the circular motion), the second fixed-side molded part 51 and the second movable-side molded part 70 are joined, and the second workpiece M2 is formed. Processed. As the second movable side pressure member 76 moves forward, the first movable side pressure member 66 integrally formed with the movable side pressure piston 67 is interlocked with the lower surface of the first movable side molding portion 60. Move forward to be flush with each other. Further, as the movable member 30 moves backward, the first fixed pressure member 46 moves backward so as to be flush with the upper surface of the first fixed molding part 41, and the processed first workpiece M1 is taken out. The first workpiece M1 is newly replenished.

  In addition, after the crankshaft 22 reaches around 360 ° of circular motion, that is, near 0 °, the crankshaft 22 operates from about 0 ° to about 90 ° of the circular motion (see blank portion D in FIG. 9), and the movable member. 30 is advanced to a substantially middle point between the first fixed side member 40 and the second fixed side member 50, and thereafter, returning to the beginning, the same process is repeated.

  As described above, in the bidirectionally operated mechanical press device 10 of the present invention, the crank mechanism portion is different from the conventional mechanical press device that performs one machining while the movable member 30 reciprocates once. While the 20 crank arms 22 advance and retract and the movable member 30 reciprocates once in the machine base 11, the first workpiece M1 is processed at the forward position of the crank arm 22, and the second workpiece is processed at the retracted position. The material M2 can be processed. Therefore, the energy of the circular motion of the crank mechanism can be efficiently used as the applied pressure as compared with the conventional case.

  Further, the bidirectionally operated mechanical press device 10 includes a first fixed-side pressure member 46 that is operated by a cylinder device 45 provided in the first fixed member 40 in the first fixed-side molding portion 41, and The second fixed side molding part 51 has a second fixed side pressure member 56 operated by a cylinder device 55 provided on the second fixed member 50, and includes a first movable side molding part 60 and a second movable side molding part 70. In the operation of the first movable-side pressure member 66 and the second fixed-side pressure member 56, which are advanced and retracted in conjunction with the operation of the first fixed-side pressure member 46 by the cylinder device 35 provided in the movable member 30. Since the second movable-side pressure member 76 that moves back and forth in conjunction is provided, the applied pressure acting on the first workpiece M1 and the second workpiece M2 can be maintained constant, which is desired. It becomes possible to stably obtain the applied pressure.

  Further, since the first movable side pressure member 66 and the second movable side pressure member 76 are actuated by a single cylinder device 35, the first and second movable side pressure members 66, 76 are simplified. It becomes possible to operate efficiently with the configuration.

  The bidirectionally operated mechanical press device of the present invention is not limited to the above-described embodiment, and can be implemented by appropriately changing a part of the configuration without departing from the spirit of the invention. . For example, in the embodiment, the first movable-side pressure member and the second movable-side pressure member are integrally formed by the movable-side pressure piston. It can also be configured to operate.
