Description

  The present invention relates to a forging device capable of generating electric power by utilizing rotation of a flywheel, and an electric power generation system used therefor.

  In recent years, attempts to effectively use surplus energy have been made in many fields due to demands for clean energy. Also in the press device, a proposal that uses surplus energy for power generation has been made, paying attention to the fact that only a part of the energy stored in the flywheel is consumed for the work of pressing, which is the original function. (See Patent Document 1).

JP 2009-90325 A

  By the way, in press working, although a very strong force is required even though it is a part of the accumulated energy as described above, precision is required for the configuration of the flywheel that stores energy.

  However, in the proposal described in Patent Document 1, since the rotary motion of the flywheel is changed to a linear motion and then converted into the rotary motion to generate power again, the rotational performance of the flywheel is affected. There is a risk. Moreover, since the above-described motion conversion is involved for power generation, the energy loss increases, and it is difficult to fully utilize the surplus energy stored in the flywheel.

  An object of the present invention is to provide a forging device that can generate power without affecting the rotational performance of a flywheel, and that can generate a large amount of power generation with little energy loss, and a power generation system used therefor. .

  <1> A forging device including a flywheel and having a processing unit that is operated by forging or forging a workpiece by rotating the flywheel, the rotating member rotating with the rotation of the flywheel; A forging device comprising: a generator that rotates to generate electric power when the rotation of the rotating member is transmitted.

  <2> The forging device according to <1>, including a motor connected to the flywheel, and the rotating member includes a member bridged between the motor and a member connected to the generator.

  <3> The forging pressure device according to <1> or <2>, wherein the forging pressure device is a press device, a bender device, or a hammer device.

  <4> A power generation system including a flywheel and used in a forging apparatus having a processing unit that is operated by rotating the flywheel and forging or forging a workpiece. A rotating member that rotates and a generator that generates power by rotating when the rotation of the rotating member is transmitted.

  According to the forging device of the present invention, the generator included in the forging device generates electric power by transmitting the rotation of the rotating member that rotates with the rotation of the flywheel. Electric power can be generated simply by adding a rotating member as an element. As a result, power generation is possible without affecting the rotational performance of the flywheel.

  Further, since the rotary motion of the flywheel is transmitted to the generator by the rotary member while maintaining the rotary motion, a large amount of power generation can be obtained with little energy loss.

  According to the power generation system of the present invention, the generator included in the power generation system generates power by transmitting the rotation of the rotating member that rotates along with the rotation of the flywheel included in the forging device, so the flywheel on the forging device side can be modified. You can generate electricity without having to do it. As a result, power generation is possible without affecting the rotational performance of the flywheel.

FIG. 1 is an overall schematic view of a press apparatus according to the present invention. FIG. 2 is an enlarged view of the power generation system of the present invention.

  Embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings, and repeated description thereof is omitted as much as possible. Further, for the purpose of facilitating understanding, there is no problem in explanation of the present invention, in which the scale is different depending on the constituent elements, and the portion that should not be visible if it should be represented by a broken line should be represented by a solid line. In some cases, those skilled in the art may omit the members that are known to exist.

  FIG. 1 is an overall schematic view of a press device (forging device) according to the present invention, and FIG. 2 is an enlarged view of a power generation system according to the present invention.

  As shown in FIG. 1, the press apparatus 1 is mainly comprised from the apparatus main body 10, the process part 20, the flywheel 30, the belt 35, the motor 40, and electric power generation system S1 of this invention. . The power generation system S <b> 1 includes a V belt (rotating member) 45, a V pulley (member connected to the generator) 50, a speed reducer 55, and a generator 60.

  The apparatus main body 10 has the same structure as that of a general press apparatus, and a foot 11 is formed on the bottom, so that vibration that can be generated by pressing is easily absorbed.

  The processing unit 20 has the same configuration as that of a general mechanical press device, and includes a processing unit main body 21, a crankshaft 22, a slide 23, and a connecting rod 24. The processing portion main body 21 has a substantially rectangular shape that is long in the height direction, and is connected to the flywheel 30 by a crankshaft 22 that extends in the horizontal direction at the top. The slide 23 is attached to a connecting rod 24 that is connected to the crankshaft 22 and extends downward, and can move up and down.

  On the other hand, a bolster plate 25 is provided below the processing unit 20 so as to face the processing unit 20, and a workpiece (workpiece) to be pressed such as a metal plate is placed thereon during the operation. The slide 23 is pressed.

  When performing the press, the processing unit 20 controls the press device 1 by a control unit (not shown) to start the work and rotates the flywheel 30, and this energy is transmitted to the crankshaft 22. As a result, the slide 23 is lowered to press the workpiece on the bolster plate 25. When the press is completed, the slide 23 is raised and returned to the initial position.

  In the flywheel 30, the crankshaft 22 is connected to the center of the support shaft 31, and the belt 35 is suspended.

  Moreover, the power generation system S2 of the present invention that performs auxiliary power generation is provided on the side surface. The power generation system S <b> 2 includes an auxiliary generator (generator) 32 and a roller (rotating member) 33, and the auxiliary generator 32 is connected to the flywheel 30 via the roller 33.

  In the power generation system S2, the roller 33 is attached to the flywheel 30, and rotates dependently with this rotation. Therefore, when the flywheel 30 rotates, the auxiliary generator 32 generates power by being transmitted by the rotational force transmitted by the roller 33 as it is rotated, and the electric power is output (FIG. 3). Middle arrow). As the auxiliary generator 32, for example, a small generator such as a dynamo can be suitably used. In the illustrated example, a roller generator is used, but a hub generator may be used. Further, the roller 33 may be one attached to the auxiliary generator 32, or if a protrusion is already formed on the flywheel 30, it may be applied as a fixture.

  In the motor 40, a motor main body 42 is placed on a motor base 41, and a belt 35 is hung on a first pulley 44 a fitted on a shaft 43 extending from the motor main body 42. That is, the motor 40 is bridged with the flywheel 30 by the belt 35.

  The motor 40 is driven to perform an auxiliary function for the flywheel 30. That is, in order to start the flywheel 30 stopped at the start of the press work or to recover the inertia energy of the flywheel 30 lost by the press work and keep it constant, the drive is driven by the control of the control unit. The force is transmitted to the flywheel 30 via the belt 35. Moreover, it is also possible to rotate according to the increase in the rotational speed of the flywheel 30.

  A second pulley 44b having a diameter smaller than that of the first pulley 44a is fitted on the front end side in the axial direction of the first pulley 44a of the motor 40, and the V belt of the power generation system S1 is fitted to the second pulley 44b. 45 is hung.

  In the power generation system S <b> 1, the generator 60 is connected to the speed reducer 55, and the speed reducer 55 is further connected to the V pulley 50. A V belt 45 is hung on the V pulley 50, so that the V belt 45 is bridged between the motor 40.

  The configuration of the power generation system S <b> 1 will be described in detail. As shown in FIG. 2, the speed reducer 55 and the power generator 60 are arranged on the installation base 15 on the apparatus main body 10.

  The reduction gear 55 includes a housing 56 in which a reduction gear 57 is housed. Of the two shafts 58a and 58b of the reduction gear 57, one shaft 58a is the V pulley 50 and the other shaft 58b is a power generator. Are connected to each other. The shafts 58a and 58b are fitted with bearing units 59a and 59b, respectively, whose front ends are substantially weight-shaped, and both are oriented in the same direction.

  The generator 60 is an out-rotor type in the illustrated example, and an inner fixed shaft 61 is fixed to a mounting column 16 that protrudes upward at an end opposite to the V pulley 50 of the installation table 15. The rotating body 62 is rotatably attached to the fixed shaft 61. With this configuration, the generator 60 generates electric power by rotating the rotating body 62, and can output electric power from the fixed shaft 61 (see arrows in the figure). The type of the generator 60 is not limited to this out rotor type, and may be an inner rotor type or a small one, but a large output is obtained and it is easy to rotate at a constant speed. An out-rotor type is preferably used.

  With the above configuration, in the power generation system S1, when the motor 40 is driven, the V-belt 45 rotates (rotates) along with this, and the rotational force of the motor 40 is transmitted to the V pulley 50 in a rotational motion. Then, after the rotational speed is appropriately reduced by the speed reducer 55, the rotational speed is transmitted to the generator 60 and the rotating body 62 rotates to generate power. Further, when the energy of the flywheel 30 is surplus, the rotational force is transmitted to the motor 40 via the belt 35 and further transmitted to the generator 60 in the same manner as the driving force of the motor for use in power generation.

  In the press apparatus 1, the energy stored in the flywheel 30 is used for the press work only about 10% or less during the operation of the flywheel 30. Therefore, the present inventor considered that utilizing surplus energy that is not used for the press work for power generation is extremely effective particularly in the current situation where an energy supply means to replace nuclear power generation is strongly demanded. However, considering only taking the energy of power generation directly from the flywheel 30, the flywheel 30 will be modified, and even if power generation becomes possible, it will affect the rotational performance of the flywheel, There is a possibility that the press capability which is the original function of the press apparatus 1 may be reduced.

  Therefore, the present inventor first tried to easily attach the auxiliary generator 32 via the roller 33 without remodeling the flywheel 30. As a result, the rotational force of the flywheel 30 is transmitted to the auxiliary generator 32 through the roller 33 without being converted into a rotational motion, and even if it is a small-scale generator without generating any energy loss. Significant power generation was obtained.

  Next, the present inventor assists the flywheel 30 when the motor 40 requires the most pressing force after the rotational speed of the flywheel 30 is increased and sufficient inertial energy is obtained. Since it is not driven except for driving as much as possible, we focused on utilizing this driving force for power generation. That is, according to this, even if a larger generator was attached, it was thought that the influence on the operation for press working of the flywheel 30 could be almost completely eliminated.

  Therefore, when the driving force of the motor 40 is transmitted to the generator 60 via the V-belt 45, the output expected by the press device described in Patent Document 1 (Japanese Patent Laid-Open No. 2009-90325) is 10 times or more. We were able to obtain the amount of power generation. That is, according to this configuration, it is possible to generate power that can be used in applications that do not stop at emergency power generation during a power failure without affecting the rotational performance of the flywheel 30.

  Further, in the present invention, since the mounting structure of the generators 32 and 60 is simple without modification of the flywheel, there is an advantage that power can be generated even in a small press device. Therefore, it can be applied to, for example, battery charging.

  Note that the reduction ratio of the V pulley 50 with respect to the speed of the V pulley 50 by the speed reducer 55 and the speed of the rotating body 62 of the generator 60 are the actual processing work in the press device 1, the speed of the motor 40, and the allowable speed of the rotating body 62. What is necessary is just to set suitably according to rotation speed.

  As mentioned above, although embodiment of this invention was described in detail, the press apparatus and power generation system of this invention are not limited to the said embodiment, You may include all the technical thoughts assumed within the range. For example, the power generation system S2 by the auxiliary generator 32 may not be provided, and conversely, only this may be provided. Further, in the power generation system S <b> 1, the rotation of the V pulley 50 may be directly transmitted to the generator 60 without providing the speed reducer 55.

  Furthermore, in the said embodiment, although the case of the press apparatus was demonstrated to the example as a forge pressure apparatus, another forge pressure apparatus may be sufficient. Here, the forging device is a general term for a forging machine and a forging machine, and means a metal processing machine and a metal forming machine other than a machine made by cutting with a tool. It can be suitably applied.
