Description

  The present invention relates to a forging machine that performs forging with a punch and a die, and more particularly to a cover structure that covers a forging main body.

  In the forging machine, when forging is performed in a forging main body having a punch and a die, oil is appropriately sprayed and used as a coolant in order to cool and lubricate the punch, the die, and the workpiece. For this reason, for the purpose of improving safety and hygiene, it is common to provide a cover for preventing oil scattering and oil mist leakage around and above the forging main body. In the forging main body portion, electric devices such as pressure devices and motors using air pressure and hydraulic pressure are used. For this reason, for example, piping and electrical wiring are housed in a protective tube called a precica tube to prevent direct contact with oil, and oil resistance is improved.

  The above-described cover and protective tube are widely used not only for forging machines but also for general machine tools that use coolant. For example, the cover structure of a machine tool disclosed in Patent Document 1 is fixed to a plurality of locations on both the left and right side surfaces of a bed, and has a lower column that oil-tightly penetrates a coolant pan, and an upper surface of the cover that is coupled to the upper end of the lower column. The lower support post and the upper support post constitute a duct such as electric wiring or hydraulic piping. As a result, the action is described in which the support is positioned in the cover, the appearance of the cover is refreshed, and the coolant leakage prevention structure is easily formed.

  In this type of cover, in order to ensure mechanical strength, a plurality of steel plates having a certain thickness are often welded to form an integrated cover that covers the entire machine tool. It is also known to weld a reinforcing stay to a steel plate in order to reduce the thickness of the cover. In many cases, the protective pipe for housing the piping and the electric wiring is fixed along the forged main body part or along the inner wall surface of the cover.

Japanese Patent Laid-Open No. 6-246581

  By the way, when a trouble occurs in the forging main body, it may be necessary to temporarily disassemble and remove the cover for internal investigation or part replacement. At this time, the conventional covers including Patent Document 1 are problematic because disassembly workability is not considered. For example, an integrated cover with a welded structure is practically difficult to disassemble, and internal investigations and parts replacement have been time-consuming. Also, with a cover made up of a plurality of components, the detachment work is not easy even if it can be removed, and the disassembly workability is remarkably low due to restrictions on weight and shape. In addition, it may be necessary to investigate the piping and electrical wiring in the protective tube, or when replacing parts of the piping and electrical wiring when replacing parts, the disassembly range will be expanded and the disassembly work content will be diverse and difficult. It was.

  The present invention has been made in view of the problems of the above-described background art, improves the disassembly workability of the cover covering the periphery and upper part of the forging main body part, facilitates maintenance such as internal inspection and parts replacement, and is oil resistant.

  Further, at least a part of the panel member may be a door panel that is movable in an attached state.

  In the forging machine of the present invention, the cover is detachably attached to at least one of the frame member having a predetermined mechanical strength, the frame member, the base portion, and the forging main body portion, and is connected to each other to surround the forging main body portion. And a plurality of panel members covering the top. For this reason, it is possible to divide the panel member into a plurality of pieces as appropriate from the beginning assuming attachment / detachment work, and the panel member can be reduced in weight because it is supported by a frame member or the like and does not require large mechanical strength. Therefore, the cover can be disassembled simply by removing the lightweight panel member while leaving the frame member, disassembling workability is significantly improved, and maintenance such as internal investigation and parts replacement is facilitated.

  Furthermore, in the aspect in which the framework member is configured using a pipe material, the internal space of the pipe material can be used for at least one of the pipe and the electrical wiring. Therefore, it is possible to prevent the piping and electrical wiring from directly contacting the oil by using the frame member also as a protective tube, and the oil resistance can be improved.

  Furthermore, in the aspect which provided the cover member which can open and close internal space in a pipe material, a piping relay part and a relay terminal block can be arrange | positioned in the internal space inside a cover member. Accordingly, the lid member can be removed to conduct investigations and connection work of piping and electrical wiring, thereby facilitating maintenance of internal investigations and parts replacement.

  Moreover, in the aspect which a part of panel member has an outer frame panel and a center panel, it can choose to remove an outer frame panel and a center panel collectively, and to remove or open and close only a center panel. Accordingly, the disassembly range is appropriately selected according to the content of maintenance, and maintenance can be performed efficiently with minimum effort.

  Moreover, in the aspect which is a door panel which can move in the state in which a part of panel member was attached, the contact to a forging main-body part, visual observation, approach, etc. can be performed by movement of a door panel. Therefore, normal operation can be performed easily and efficiently.
