Problems solved by technology

[0008] In this way, in the conventional production facilities, since the A-class panel Pa, the B-class panel Pb, and the C-class panel Pc are manufactured by using the dedicated press machine Aa, the press machine Ab, and the press machine Ac, respectively, all the components constituting a car are manufactured. Sheet metal requires multiple press processing lines, which inevitably has the problem of unreasonably large-scale production equipment

Embodiment Construction

[0035] Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments.

[0036] Figure 1 ~ Figure 4 An example of applying the die cushioning device of the present invention to a press machine for processing a metal material (work) into a plate of a desired shape in a production facility such as an automobile is shown. In addition, the overall composition of the press machine, due to the Figure 16 The conventional press machine A shown is basically unchanged, so a detailed description of the overall configuration of the press machine will be omitted.

[0037] Such as Figure 1 ~ Figure 3 As shown, the first unit (die cushion unit) 11, the second unit (die cushion unit) 12, the third unit (die cushion unit) 12, and the third Unit (die buffer unit) 13 and fourth unit (die buffer unit) 14.

[0038] The first unit 11 has a rectangular cushion pad 11P in plan view, and a pair of hydraulic servo cylinders 11S, 11S as a lift dri...

Abstract

The invention aims to provide a die cushion apparatus of a press machine, which makes possible to manufacture a plurality of types of products of different sizes by one press machine and capable of minimizing a production facility, and comprises a plurality of die cushion units, each of which has a cushion pad and a rise and fall drive unit for vertically driving the cushion pad, that are aligned in a direction perpendicular to a work conveying direction, and a control unit capable of individually and independently controlling the plurality of die cushion units.

Description

technical field [0001] The present invention relates to a die cushioning device for a press machine, in particular to a die buffer device for a press machine suitable for use in production equipment for manufacturing various products of different sizes. Background technique [0002] Figure 16 The shown press machine A for deep drawing has a lower die (punch) E installed on the bed B, and an upper die (concave) U installed on the slider S. The mold buffer device C inside the body B, and the binder ring H that moves up and down through the buffer rod R. [0003] The above-mentioned die cushioning device C has a cushion Cp installed inside the bed B to be able to move up and down freely, and a hydraulic servo cylinder Cs for moving the cushion Cp up and down. When the material W is further processed by lowering the slide S , by pressing the material W onto the upper mold with a specified pressure through the binder ring H, it plays a role in preventing "cracks" or "wrinkles" ...
