Detailed Description

The following will further describe a cushion mechanism of an open press according to the present invention with reference to fig. 1 to 3.

Referring to fig. 1-3, the buffer mechanism of the open press according to the embodiment includes an open press 1, a push rod 201 is disposed on the open press 1, a platen assembly 3 is connected to the push rod 201, and the open press 1 is further provided with a platen 4 matched with the platen assembly 3 through a screw, and is characterized in that the platen assembly 3 includes a buffer mechanism 301 disposed on the push rod 201 and a platen 302 mounted on the buffer mechanism 301; open press 1 drives clamp plate assembly 3 and carries out the punching press to installing the work piece on pressing platform 4, can play the cushioning effect through buffer gear 301 at the in-process of punching press, avoids clamp plate and equipment to lead to the collision dynamics too big because of the speed is too fast, the condition that equipment and work piece damaged appears.

Referring to fig. 2, the buffer mechanism 301 includes an upper press plate 3011 welded to the push rod 201, a lower press plate 3012 bolted to the upper press plate 3011, and an intermediate buffer plate 3014 installed between the upper press plate 3011 and the lower press plate 3012, and the press plate 302 is installed on the lower press plate 3012 by bolts; the upper press plate 3011 and the lower press plate 3012 which are detachable through bolts can facilitate installation and replacement of the middle buffer plate 3014.

Referring to fig. 2, an installation groove 3015 is provided on the upper pressing plate 3011 and the lower pressing plate 3012, the middle buffer plate 3014 is installed between the upper pressing plate 3011 and the lower pressing plate 3012 through the installation groove 3015, the lower pressing plate 3012 is further provided with a through hole 3016, the middle buffer plate 3014 is provided with a support leg 3017 adapted to the through hole 3016, the upper pressing plate 3011 and the middle buffer plate 3014 are further provided with a limit hole 3018, and a spring 303 is further installed in the limit hole 3018; when the device is used for stamping, the support feet 3017 are firstly contacted with the pressing table 4, and the middle buffer plate 3014 is matched with the upper pressing plate 3011 to press the spring 303, so that the buffer effect is achieved.
