Further, wheels 14 are provided on the lower surfaces of the four corners of the leg portion 12.

  The upper mold 20 is a mold that has a pressing surface 20 a that presses the sheet metal w against the lower surface, and is provided above the base 10. The upper mold 20 is provided lying on the upper side of the base 10. More specifically, the upper mold 20 shown in the present embodiment is a thick plate material having a substantially rectangular shape when viewed from the front, and as shown in FIG. 4, a pressing surface 20a that is inclined to the lower end is formed when viewed from the side. ing. And the plate receiver 22 used as the base for the attachment of the upper metal mold | die 20 is provided in the lower surface of the upper horizontal material 10d of the frame 10a of the base 10, and it extends in the horizontal direction, and protrudes below from the plate receiver 22 An attachment plate 24 is provided, and the upper mold 20 is sandwiched between the attachment plate 24 and a clamp 26 fixed to the attachment plate 24 with bolts 28. As shown in FIGS. 1 and 3, the upper mold 20 is multi-divided. However, for example, the upper mold 20 may be divided and is not limited by the form.

  The lower mold 30 is a mold that has a pressing surface 30 a that presses the sheet metal w against the upper surface and is disposed below the upper mold 20. The lower mold 30 is disposed lying between the left and right columns 10 b and 10 c of the base 10. More specifically, the lower mold 30 shown in the present embodiment has a substantially square pillar shape, and as shown in FIG. 6, the lower surface is supported by a mold cradle 32, and between the pillar 10b and the pillar 10c. And it is provided in the front and back of pillar 10b, 10c so that it can move up and down inside the front-and-back plate 16 spanned between pillar 10b and pillar 10c.

  The cylinder 40 is for raising the lower mold 30. Specifically, the cylinder 40 is below the lower mold 30 and below the frame 10a of the base 10 so that the piston rod 42 moves up and down. It is fixed so as to stand up from the cross member 10e. The cylinder 40 is driven by a manual hydraulic pump 50. The upper end of the piston rod 42 is in contact with the lower surface of the mold cradle 32 so as to push up the mold cradle 32.

  The manual hydraulic pump 50 is connected to the cylinder 40 by a pipe (not shown), and by operating the pump handle 52 by hand, hydraulic pressure is applied to the cylinder 40 and the piston rod 42 extends. The manual hydraulic pump 50 of this embodiment has a pressure gauge 56 for monitoring the hydraulic pressure, but it is not essential. In addition, there is no particular limitation as to which position on the base 10 and in what direction the manual hydraulic pump 50 is installed, but it is preferable that the manual hydraulic pump 50 be arranged so that the pump handle 52 is easily operated. In the embodiment, it is installed and fixed to a pump base 58 that extends in the front-rear direction at a substantially middle position above and below the right column 10 b of the frame 10 a of the base 10. In this case, the direction of the pump handle 52 is an easy direction to operate from the front of the base 10.

  Note that the cylinder 40 and the manual hydraulic pump 50 are not necessarily limited, but in the present embodiment, the cylinder 40 is configured to single-act, and the single-acting operation and the like will be described later.

  Next, the usage method of the above manual press apparatuses 1 is demonstrated. First, as shown in FIG. 1, the operation starts from a state where the lower mold 30 is lowered (a state where the piston rod 42 of the cylinder 40 is not raised). In this state, the sheet metal w desired to be molded is placed as shown in FIG. The position where the sheet metal w is placed is a position where the upper metal mold 20 and the lower metal mold 30 can form (bend) the sheet metal w at a desired position.

  Next, the pump handle 52 of the manual hydraulic pump 50 is operated to drive the cylinder 40 and raise the piston rod 42. Then, the lower mold 30 is raised by the piston rod 42. Then, as shown in FIG. 4B, the sheet metal w disposed between the upper mold 20 and the lower mold 30 is pressed between the lower mold 30 rising toward the upper mold 20. And mold.

  After the molding of the sheet metal w is finished, the manual pressure pump 50 is operated to lower the lower mold 30 to complete the operation.

  According to the manual press device 1 having the above-described configuration, the cylinder 40 for raising the lower mold 30 is provided under the lower mold 30, and the structure of the base 10 is easy and the movement is easy.

  Note that the cylinder 40 and the manual hydraulic pump 50 can be structured so that the cylinder 40 is single-acted. The cylinder 40 and the manual hydraulic pump 50 shown in the figure are single-acting structures, and the piston rod 42 of the cylinder 40 extends. When the lower mold 30 is raised, the pressure of the manual hydraulic pump 50 is released by operating the pressure release lever 54 which is the pressure release means, the cylinder 40 loses the lifting force, and the piston rod 42 is contracted. In this case, the lower mold 30 is lowered halfway. In this way, by adopting a structure in which the cylinder 40 is single-acted, the lower mold 30 can be quickly lowered by a simple operation.

  In addition, the base 10 is provided with a frame portion 10 a having a substantially rectangular shape in front view, the upper mold 20 is provided on the upper side of the base 10, and the lower mold 30 is provided on the base 10. If it is arranged lying between the left and right columns 10b, 10c, the structure of the manual press device 1 can be made robust.

  Further, the base 10 is provided with a leg portion 12 which is integrated with the frame body portion 10a and has an inverted T shape in a side view at the lower portion of the frame body portion 10a, whereby the manual press device 1 is installed on the floor surface. Will be stable.

  Furthermore, the manual press apparatus 1 can be easily moved by providing the leg 12 of the base 10 with the wheels 14 on the lower surface.

  Moreover, in the manual press apparatus 1 of this Embodiment, although not essential, the sheet metal w positioning mechanism 60 shown in FIG.5 and FIG.6 is provided. The positioning mechanism 60 is provided so as to be slidable in the direction of the pressing surface 20a of the upper mold 20 on the guide rails 62a and 62b that are horizontally provided so as to protrude from the columns 10b and 10c of the base 10 and the guide rails 62a and 62b. And a stopper plate 64 that abuts the end of the sheet metal w.

  More specifically, the guide rails 62 a and 62 b are provided horizontally by protruding from the pillars 10 b and 10 c of the base 10 by the guide rail fixing plate 80. A linear guide 68 that slides on each of the guide rails 62 a and 62 b is provided. A stopper receiver 66 is bridged between the linear guides 68, and a stopper plate 64 is fixed to the stopper receiver 66. The stopper plate 64 is provided in parallel with the upper die 20 and the lower die 30 in the horizontal direction of the manual press device 1, and the contact surface 64a with the sheet metal w is directed in the front direction. It is provided as follows.
