Automatic lubricating device for perforating needle of extruding machine

The utility model discloses an automatic lubricating device for a perforating needle of an extruding machine. The automatic lubricating device comprises an extruding machine rack, the guide column is fixedly mounted on the outer surface of the extruding machine rack; the hydraulic extrusion head is fixedly mounted at the top of the extruder rack; and the temperature control lubricating device comprises a lubricating liquid storage box, a cooling water storage box, a first pump machine and a second pump machine. When the hydraulic extrusion head is pressed downwards to conduct extrusion operation, a first pump pumps lubricating liquid in a lubricating liquid storage box into a second annular spraying head through a first water pipe to spray the lubricating liquid to the surface of the perforating needle, and a temperature sensor detects the temperature of the hydraulic extrusion head; and in the lifting process of the hydraulic extrusion head, a second pump machine is started to pump cooling liquid in a coolin
