Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finishing workbench for fixing a die and performing a finishing work, and more particularly to a finishing workbench for finishing a die after machining by a machine tool.

[0002]

2. Description of the Related Art Conventionally, finishing work has been required to manufacture a mold. In particular, a die is manufactured by performing a finishing operation after a metal material is carved by a machine tool. This finishing work is a work in which the operator manually prepares a machined surface by manually removing the tool marks after the carving process using a grinder, sandpaper, a grindstone, or a file and polishing. Since this work requires skill and skill from experience, it is almost impossible to mechanize, and it is still performed manually. In recent years,
It is also considered to reduce the load of finishing by reducing the tool pitch of the die-cutting process, but it is impossible to arrange the machined surface smoothly by only the die-cutting process,
Manual finishing work is still required.

[0003]

However, since this finishing work is performed by placing the mold on the floor, the worker must perform the work in an unnatural posture in which the worker bends his waist. For this reason, the finishing work is a laborious work, and if it is done for a long time, it may hurt the waist and is a difficult work.
Further, even if the mold is placed on wood or the like for finishing work, the position and direction of the mold, which is a heavy load, cannot be changed, and it is still heavy labor. Further, since the direction of the mold cannot be changed, there are cases where it is not possible to accurately finish parts that are difficult for the operator to reach. Further, since the direction of the mold cannot be changed, it is not possible to apply force to the grindstone or file depending on the part to be finished, resulting in poor work efficiency.

Therefore, the present inventor has accomplished the present invention as a result of earnest studies to solve such problems.

[0005]

SUMMARY OF THE INVENTION A gist of a finishing workbench according to the present invention is that a base is fixed on a floor, and is supported on the base and can be tilted with respect to the base by tilt drive means. The tilting plate and a platen which is supported on the tilting plate so as to be rotatable in a plane direction substantially parallel to the tilting plate and to which a mold is fixed are provided.

Further, in the finishing workbench according to the present invention, the base is slidable in the vertical direction by the sliding drive means.

[0007]

In the finishing workbench according to the present invention, first, the die for carving is performed by the machine tool and the die to be subjected to the finishing work is fixed on the surface plate with its working surface facing upward. While the mold is fixed on the surface plate with the machining surface facing up, the operator will manually perform the finishing work on the machining surface of the mold facing upward using a grinder or grindstone. .

Here, by operating the tilt drive means, one end of the tilt board is pushed up or pushed down, and the tilt angle of the tilt board is adjusted. By adjusting the tilt angle of the tilting plate, the operator can easily apply a force to the grindstone, the file, and the like, and the tilt angle of the mold is adjusted so that the worker can work in a comfortable posture. Further, by rotating the surface plate in a plane direction substantially parallel to the inclined plate, it is easy for the operator to reach the part of the mold for finishing work, or it is easy to apply force to the grindstone or the like. , The direction of the mold can be changed.

In this way, the operator finishes the mold while freely changing the position and direction of the mold three-dimensionally, and the mold after the finishing work is removed from the surface plate. The mold removed from the surface plate is used by being attached to a molding machine, a press machine or the like.

Further, in the finishing work table of the present invention in which the base is slidable in the vertical direction by the sliding driving means, the sliding driving means is operated before or during the finishing work. As a result, the base is slid up and down, and the height of the base is adjusted. By adjusting the height of the base, the height of the mold is adjusted according to the height of the worker or in a comfortable posture. Also, since the base can be slid up and down by the sliding drive means, the base can be lowered when attaching and detaching the mold to facilitate the work of attaching and detaching the mold, and the base must be raised during the finishing work. It is also possible to make finishing work easier.
