Cardan joint back-extruding guiding structure suitable for 2000T automatic mechanical press

Abstract

The invention discloses a cardan joint back-extruding guiding structure suitable for a 2000T automatic mechanical press. The cardan joint back-extruding guiding structure comprises an upper punch spraying cooling guiding device and a lower die spraying cooling guiding device; the upper punch spraying cooling guiding device comprises an upper die body and an unloading ring; the upper die body and the unloading ring are connected through a pulling rod; the upper die body is provided with a punching head; the punching head penetrates through the unloading ring and protrudes from the unloading ring; a plurality of penetrating first damping holes are formed in the unloading ring; the punching head comprises a guiding part and an extruding part; the lower die spraying cooling guiding device comprises a lower die body and a guiding sleeve which are connected; the guiding sleeve is positioned above the lower die body and is matched with the guiding part of the punching head; a penetrating second damping hole is formed in the guide sleeve; a cavity which is matched with the extruding part of the punching head is formed in the lower die body, and the upper part of the cavity is a guiding area which is matched with the guiding part; and the lower part of the cavity is an extruding area which is matched with the extruding part. The cardan joint back-extruding guiding structure can realize the triple effects of guiding, spraying and unloading.

Description

technical field [0001] The invention belongs to an anti-extrusion guide structure, and more specifically relates to an anti-extrusion guide structure suitable for 2000T automatic mechanical pressure and universal joints. Background technique [0002] At present, the domestic universal joint guide devices mainly have the following status and problems: (1) The ordinary manual universal joint production line can realize guiding and spray cooling at the same time, but due to the low precision of the equipment itself, the coaxiality of the product can only reach 0.8 -1.2, followed by machining to meet customer requirements. Moreover, it is easy for the product to stick to the punch during the production process. The disadvantages of this process are: low material utilization rate, high processing cost, long production process, and low production efficiency. [0003] (2) 2000T automatic production line. Due to its high guiding precision, the coaxiality of universal joints produce...
