Embodiment approach 1

[0041] use Figure 1 to Figure 5 The press apparatus 100 which concerns on Embodiment 1 of this invention is demonstrated. figure 1 It is a perspective view showing the structure of the press apparatus 100, figure 2 It is a front view which shows the structure of the press apparatus 100. The press apparatus 100 includes a first die 110 , a second die 120 , drive units 130 a to 130 d , and a base 140 . The press apparatus 100 processes the workpiece by sandwiching the workpiece between the first mold 110 and the second mold 120 .

[0042] The base 140 is fixed to the ground, and supports the first mold 110, the second mold 120, and the drive units 130a to 130d. The second mold 120 is fixed on the base 140 fixed to the ground.

[0043] The first mold 110 and the second mold 120 are molds for clamping a workpiece and processing the workpiece. In the press apparatus 100, the first die 110 functions as an upper die, and the second die 120 functions as a lower die. The 1st me...

Embodiment approach 2

[0075] use Figure 21 The press apparatus 700 of Embodiment 2 is demonstrated. The press apparatus 700 includes a first die 710, a second die 720, a third die 730, drive units 130a to 130d, a base 140, and braces 740a and 740b. The press apparatus 700 processes the workpiece by sandwiching the workpiece between the first mold 710 and the second mold 720 and between the first mold 710 and the third mold 730 .

[0076] In the press apparatus 700 , the second die 720 is fixed on the base 140 , and the second die 720 is provided with support rods 740 a and 740 b. Two through holes are provided in the first mold 710, and the first mold 710 is disposed in a state capable of moving along the stays 740a and 740b through the through holes. The third mold 730 is fixed to the uppermost parts of the stay bars 740a and 740b. The first mold 710 can be moved up and down by the drive units 130a to 130d.

[0077] The third mold 730 is arranged so that the first mold 710 is arranged between...

Abstract

The invention provides a stamping device, a production line and a manufacturing method of the stamping device. In the punching device (100) of the present invention, it is equipped with: a first mold (110); a second mold (120) that clamps a workpiece together with the first mold (110) to process the workpiece; 1 mold (110) is connected with the 2nd mold (120), and the plurality of driving units (130a~130d) that make the space between the 1st mold (110) and the 2nd mold (120) change, the 1st mold (110) and The second mold (120) has connecting parts (111a-111d and 121a-121d) respectively connected to the driving units (130a-130d), and at least one of the first mold (110) and the second mold (120) has a reinforcing part (113a-113d).

Description

technical field [0001] The present invention relates to a stamping device, a manufacturing line, and a method for manufacturing the stamping device. Background technique [0002] Various stamping devices are used in the forming of metal parts. For example, Patent Document 1 discloses a press apparatus capable of reducing the maximum load applied to a workpiece during press forming. In the press apparatus of Patent Document 1, a plurality of drive units support the upper die plate and the lower die plate. The upper die of the mold is fixed on the lower side of the upper die plate, and the lower die is fixed on the upper side of the lower die plate. Since a plurality of drive units can be independently controlled, the maximum load at the time of molding can be reduced by lowering the upper die plate while oscillating. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-125834 [0004] In the press apparatus described in Patent Document 1, in order to form variou...
