The invention relates to a
lubrication device for a hydraulic drawing
machine. The
lubrication device comprises a
fuel tank (18) arranged below the drawing
machine, a path oil
distributor (13) and path oil pipes. The
lubrication device is characterized in that: the lubrication device is provided with a sliding block (6) arranged on a sliding platform of the drawing
machine; an automatic oil injection mechanism for a roller
plunger pump is matched with the sliding block (6) and is arranged between the lower side of the sliding block (6) and the
fuel tank (18); the automatic oil injection mechanism consists of a rolling
pulley (4), a guide rod (2), a spring (3) on the guide rod (2), a guide rod clamp iron track (1) and a fixing bolt (15), and a
plunger fuel pump (16) and a fixing bolt (17), wherein the rolling
pulley (4) is hinged with the guide rod (2); the rolling
pulley (4) and the fixing bolt (15) are installed on the machine body (14) of the drawing machine through the guide rod clamp iron (1); the
plunger rod of the plunger
fuel pump (16) is connected with the lower end of the guide rod (2); and the pump body of the plunger
fuel pump (16) is connected with the
fuel tank (18) through a pipeline and then connected with the path oil
distributor (13). The lubrication device has the characteristics of simple structure, low manufacturing cost, convenience of operation and maintenance, automatic and adequate
oil supply, low abrasion and the like.
