うトランスファー機構が実用化されている。2. Description of the Related Art A forging press is provided on both the left and right sides with a transport drive device, which is horizontally connected between upper and lower dies to be installed.
Combining the three-directional movement of the book beam with lifting and lowering movement (lift movement), forward and backward movement (feed movement), and opening and closing movement (clamp movement), the workpiece is grasped between the inwardly mounted fingers of both beams. A transfer mechanism that moves to a required position and releases it has been put to practical use.

種として評価されている。In the prior art, the drive of the transfer mechanism has been a mechanical transmission mechanism in which a cam mechanism, a gear and a rack, a coupling shaft, and the like are combined by mainly receiving rotation of a crankshaft of a forging press body. The process length (stroke), timing,
Equipped with a unique drive mechanism that can adjust the speed, etc., on both sides of the forging press, a system that applies a drive force controlled by a servomotor has been evaluated as a model that improves high precision and production efficiency.

本の長いビームを形成するという基本形態が採られる。The beam in the transfer mechanism cannot be applied to a single long tube. That is, dies are frequently replaced in daily forging work, but dies cannot be replaced if a beam is interposed between the upper and lower dies. Therefore, a long beam is divided into three parts, and when the mold is replaced, the connection between the intermediate beam and the left and right beams is released to make it free, and then the intermediate beam is attached together with the lower mold. And connect the left and right beams left on both sides with another new intermediate beam attached to the newly installed lower mold.
The basic form of forming a long beam of books is adopted.

る。)There are various forms for disconnecting the beam in the state of being integrally connected and retreating only the intermediate beam from the forming operation range of the forging press together with the mold. In the prior art, FIG. 6 shows an example. There are several basic types. FIG. 6A is a front view showing a general relationship between the beam 1a and the forging press F with respect to the forming mechanism of the forging press, and shows connecting portions 4a and 4b of the intermediate beam 11a.
And connecting portions 5a and 5 of the left beam 12a and the right beam 12b.
b are connected to each other to form one beam 1a. FIG. 7B shows an example of a mode in which the connection of the connecting portion is disconnected and the intermediate beam 11a is removed as free due to the necessity of changing the mold. The intermediate beam 11a is composed of two hydraulic cylinders 1 rising from a lower lower mold, more precisely, a forging press.
01, the connecting portion 4b is moved to a space higher than the connecting portion with the right beam 12b so that no interference occurs between the two. (The same applies to the left side.)

In this mode, the space 2a is retracted into the transport driving devices 2a and 2b to form a space between the connecting portions with the intermediate beam 11a to prevent interference. FIG. In this case, only one side of the form of forming a space between the connecting portions of the right beam 12b and the left beam 12a is shown, and in order to prevent interference between the connecting portions due to relative linear motion of the three members. Is common in that a space is provided.

が高騰することは避け難い。In each of the prior arts classified here as a basic form, the connection between the intermediate beam 11a and the connection between the left beam 12a and the right beam 12b is disconnected so that free movement is possible. After that, the interference of the connecting portion is prevented by the horizontal or vertical movement. Usually, the beam of the transfer press is formed by a hollow tube with a rectangular cross section, so the minimum distance required for movement to avoid interference is at least as long as one side of the cross section of the beam, If it is not greater than the vertical or horizontal dimension of, it does not match the purpose of evacuation. For example, if a method of avoiding the connecting portion by vertical movement (FIG. (B)) is adopted, generally, the size of the rectangular cross section of the beam is about 100 mm in the height direction, while the vertical movement distance of the transfer mechanism (normal) (Stroke) is set to about 30 to 60 mm. Therefore, when the mold is changed, the transfer driving device must be provided with an ability to allow an extra movement of about 40 to 70 mm or more. In other words, it is necessary to enhance the capacity of the transport drive device to match the required movement amount, and it is necessary to enable the movement amount to be greater than the original transfer function. It is unavoidable to do.

A cylinder must be built in to fit a part of the beam. For that, figure (C)
In this case, the transport driving devices 2a and 2b require a horizontal stroke longer than the normal transfer operation. In FIG. 2D, the weight of the beam itself is increased, and the structure is complicated, so that the maintenance burden is forced to increase. .

In FIG. 3, since the position of the receiving member 31 is slightly higher than the shortest height of the support cylinder 3, the beam descends more than the normal stroke at the time of mold replacement, and is first supported by the receiving member 31, and when the support cylinder 3 is raised. The free roll 33 at the tip is fitted into the triangular groove-shaped notch 13. The operation of the support cylinder is a linear motion in the vertical direction, but the left beam 12A and the right beam 12B try to make an arc motion with the engagement point 21 with the transport driving devices 2A and 2B as a fulcrum. The free roll 33 acts to gradually shift the contact point in the notch 13 formed in the bottom of the beam while rolling, thereby absorbing the difference in the amount of movement accompanying the conversion between the linear motion and the circular motion.

看過できない。According to the present invention, as described above, the intermediate beam 1 is used.
It is not necessary to add an extra large stroke of the transport driving devices 2A and 2B , which was conventionally required only for attaching and detaching the first beam 12 to and from the left beam 12A and the right beam 12B. Great saving effect. Further, in the case of the method of expanding and contracting the beam itself to avoid interference, it is no longer necessary to increase the cross-sectional area of the beam and increase the weight associated therewith.
Moreover, the connection between each beam and its release are efficient,
Since there is a great possibility that the time and labor for changing the mold can be reduced, the effect that has a positive effect on the overall productivity of the forging press cannot be overlooked.

る。According to the second aspect, the weights of the left beam 12A and the right beam 12B are once received by a receiver fixed at a position slightly higher than the tip of the support cylinder, and then the cylinders are operated to start the rotation operation. In addition, there is an effect of protecting the function of the support cylinder so as not to lose the impact at the time of weight conversion and to impair the function of the support cylinder. According to the third aspect, the connection and the release are smoothly and quickly performed by the mechanism assembled compactly. Since the connecting portion 5 of the left beam 12A and the right beam 12B protects the internal hydraulic cylinder 6 surrounded by the connecting outer cylinder 53 and the cylinder cap 62, the forging press is difficult to avoid operating conditions such as high heat, impact, and vibration. It is suitable as a device to be applied, and has the effect of maintaining a long service life. The fourth aspect of the present invention provides a forging press which operates under relatively severe operating conditions by absorbing some distortion, torsion, and other deformations of the members, since it forms a margin in the operation at the time of connection or release as described above. The effect of providing a large maintenance advantage corresponding to a slight deformation is remarkable.
