Hereinafter, the elevating range of the elevating mechanism 120 of the workbench 100 will be described.

FIG. 2 is a diagram for explaining an ascending / descending range of the workbench 100 of the first embodiment shown in FIG. 1, and FIG. 2A is a sectional view taken along line AA of FIG. 1A. 2 (b) is a cross-sectional view taken along the line BB of FIG. 1 (a). Note that FIG. 2 shows the appearance of the workbench 100 and the processing apparatus 1000.

As shown in FIGS. 2A and 2B, the workbench 100 has a base portion fitted in the first pit Pt1 formed on the floor surface FL in addition to the mounting portion 110 and the elevating mechanism 120. The base frame body 130 is provided as a base frame body 130, and the mounting portion 110 and the elevating mechanism 120 are housed in the base frame body 130. The base portion is not limited to the base frame body 130, and may be a housing other than the frame body.

The elevating mechanism 120 has a first height position higher than the floor surface FL (highest height position of the mounting portion 110) Hp1 and a second height position lower than the floor surface FL (highest height position of the mounting portion 110). It supports the mounting portion so that the mounting portion 110 can be raised and lowered from the low height position) Hp2.

Further, the working position Wp of the processing apparatus 1000 for forging is the surface of the lower die 1011 on which the workpiece is placed. This work position Wp is set to a position where a worker of average height can easily work (less tired) when working while standing on the floor FL. The workbench of the present invention can be a useful device for a forging device (air stamp hammer), which requires many operations of the processing device in the same posture for a long time.

3 is a plan view for explaining the layout of the workbench 100 and the processing apparatus 1000 of the first embodiment shown in FIG. 1, and the workbench 100 and the processing apparatus 1000 shown in FIG. 2B are C. It shows the structure seen from the direction.

As can be seen from FIG. 3, the first pit Pt1 in which the workbench 100 is housed and the second pit Pt2 in which the processing apparatus 1000 is housed are formed adjacent to each other, and the first pit Pt1 and the second pit Pt1 and the second pit Pt2 are formed adjacent to each other. It is connected to the pit Pt2.

Therefore, the workbench 100 accommodated in the first pit Pt1 can be brought closer to the processing apparatus 1000 housed in the second pit Pt2, and the workbench can be brought close to the workbench 1000 as if working on the floor surface FL. Forging work can be performed with the processing device 1000 even on the 100.

Hereinafter, an example of a specific configuration of the elevating mechanism 120 will be described.

4A and 4B are side views for explaining the structure of the elevating mechanism 120 of the workbench 100 shown in FIG. 2A, and FIG. 4A shows the mounting portion 110 at the first height position Hp1. The state of the elevating mechanism 120 at a certain time is shown, and FIG. 4B shows the state of the elevating mechanism 120 when the mounting portion 110 is at the second height position Hp2.

The elevating mechanism 120 has a base rail 120a and an elevating portion 120b provided on the base rail 120a. The elevating portion 120b is connected between the lower frame 121, the upper frame 124, the first intermediate frame 122, the second intermediate frame 123, and the first intermediate frame 122 and the second intermediate frame 123. It has an actuator 125.

Here, the lower frame 121 and the upper frame 124 are frames having the same size, and the lower frame 121 is mounted on the base rail 120a which is the base of the elevating mechanism 120. The lower end of the first intermediate frame 122 is rotatably supported by one end (right end of the paper) of the lower frame 121, and the upper end of the first intermediate frame 122 is slidable to the lower surface of the upper frame 124. It is in contact. The upper end of the second intermediate frame 123 is rotatably supported by one end (right end of the paper) of the upper frame 124, and the lower end of the second intermediate frame 123 is slidable to the upper surface of the lower frame 124. It is in contact.

In the elevating mechanism 120 having such a configuration, as the actuator 125 contracts, the inclination of the first intermediate frame 122 and the second intermediate frame 123 is paired with the horizontal plane (left-right direction on the paper surface) as shown in FIG. 4A. The upper frame 124 rises tightly with respect to the lower frame 121. On the other hand, in the elevating mechanism 120, the inclination of the first intermediate frame 122 and the second intermediate frame 123 becomes loose with respect to the horizontal plane (left-right direction on the paper surface) as shown in FIG. 4B due to the extension of the actuator 125. The upper frame 124 descends with respect to the lower frame 121.

As shown in FIG. 2, the elevating mechanism 120 is arranged on the bottom surface of the base frame body 130 fitted in the second pit Pt2, and is located between the base frame body 130 and the base rail 120a of the elevating mechanism 120. Is provided with a cushioning member 140a. Further, a mounting portion 110 on which an operator is placed is attached to the upper frame 124 of the elevating mechanism 120.

As described above, by using the workbench 100 of the first embodiment for forging with the processing apparatus 1000, the height of the worker's standing position with respect to the working position Wp of the processing apparatus 1000 is set to the floor surface FL of the building. On the other hand, it can be adjusted both on the lower side and on the upper side.

For example, as described above, the work position Wp of the processing device 1000 corresponds to a position (corresponding to a hand) where a worker of average height can easily work (less tired) when working while standing on the floor FL. When a worker who is taller than the average height of the worker works, such as when the worker comes to the position), when the worker stands on the floor FL, the work position is from the worker's hand. The distance to Wp is far compared to the case of a worker of average height. In this case, it is difficult to work, so by lowering the height of the mounting portion 110 of the workbench 100 below the floor FL, the distance from the worker's hand to the work position Wp can be adjusted to suit the tall worker. Can be a distance. As a result, it becomes possible to easily perform the work even if the work is continued for a long time. On the contrary, the work position Wp of the processing device 1000 is a position (a position corresponding to a hand) where an average height worker can easily work (less tired) when working while standing on the floor FL. When a worker who is shorter than the average height of the worker works, when the worker stands on the floor FL, from the worker's hand to the work position Wp. The distance is closer than for a worker of average height. In this case, it is difficult to work, so by raising the height of the mounting portion 110 of the work table 100 above the floor surface FL, the distance from the worker's hand to the work position Wp can be adjusted to suit the short worker. Can be a distance. As a result, it becomes possible to easily perform the work even if the work is continued for a long time.

The workbench of the present invention can be useful as a workbench for a forging device (air stamp hammer), which requires many operations of the processing device in the same posture for a long time.

Further, in the workbench 100, the floor surface FL is located between the highest height position (first height position Hp1) and the lowest height position (second height position Hp2) of the mounting portion 110. Since the height is located, when the processing device 1000 is not used, the height of the mounting portion 110 of the work table 100 can be adjusted to the floor surface FL. Therefore, the arrangement space of the workbench 100 can be used as the floor surface of the building, the workbench does not get in the way, the work space can be secured, and it is not necessary to remove the workbench 100.

Further, since the workbench 100 has the base frame body 130 constituting the workbench 100 fitted into the first pit Pt1 and fixed to the floor surface FL, the base frame body 130 of the workbench 100 is fixed to the floor surface FL. It is possible to reduce the burden on anchor bolts and the like.

As shown in FIG. 1A, the workbench 100 of the first embodiment has been described as a workbench for use in combination with the processing apparatus 1000 mounted on the floor surface FL, but the processing apparatus 1000 has been described. However, the workbench 100 of the first embodiment may be provided. In this case, the processing device 1000 may have the elevating mechanism 120 incorporated in the housing 1100 so that the elevating mechanism 120 is integrated with the housing 1100 constituting the processing device 1000.

Further, although not particularly mentioned in the first embodiment, the workbench 100 is the mounting portion 110 of the workbench 100 and the processing apparatus 1000 depending on the shape of the housing of the processing apparatus 1000 arranged adjacent to the workbench 100. The gap with the housing may widen.

In the second embodiment, a workbench 200 suitable for the processing apparatus 2000 having a skirt portion in which the housing expands from the upper side to the lower side will be described as the second embodiment.

The processing apparatus 2000 combined with the workbench 200 of the second embodiment has a skirt portion 2100a at the lower end portion of the housing 2100, which expands downward from above. Therefore, the mounting portion 110 of the work table 200 that moves up and down along the skirt portion 2100a is placed in advance so as not to interfere with the skirt portion 2100a of the housing 2100 even when it is closest to the housing 2100 of the processing device 2000. It is necessary to widen the distance between the unit 110 and the housing 2100. In this state, work chips and the like are collected from the gap between the mounting portion 110 and the housing 2100 and between the mounting portion 110 and the edge of the floor surface FL (the edge of the base frame 130). Since there is a risk of invading the base frame 130, the workbench 200 of the second embodiment is provided between the edge of the mounting portion 110 and the skirt portion 2100a in addition to the configuration of the workbench 100 of the first embodiment. It is provided with a cover body (skirt portion cover body 250) that covers the gaps between the two. The skirt portion cover body 250 has flexibility, and even if the width of the gap between the edge of the mounting portion 110 and the skirt portion 2100a fluctuates, the skirt portion cover body 250 itself is deformed. It is possible to keep the gap closed at all times.

Further, the workbench 200 includes an end cover body 260 that covers a gap generated between the end edge of the mounting portion 110 and the end edge of the base frame body 130. In the embodiment shown in the figure, the case where both the skirt portion cover body 250 and the end cover body 260 are provided is described, but the present invention is not limited thereto.
