Abstract

The invention discloses a forming die for a piston rod of a loading machine, and relates to the technical field of machining. The forming die comprises an upper extrusion die with an inner cavity, and a lower extrusion die with an inner cavity, wherein a perpendicular cylindrical hole which is communicated with the inner cavity of the upper extrusion die and leads to the exterior is formed in the upper portion of the upper extrusion die, a perpendicular cylindrical hole which is communicated with the inner cavity of the lower extrusion die and leads to the exterior is formed in the lower portion of the lower extrusion die, and horizontal semi-cylindrical holes are formed on one side of the upper extrusion die and the same side of the lower extrusion die respectively, and are communicated with the corresponding inner cavities; an upper extrusion head is arranged in the perpendicular cylindrical hole of the upper extrusion die, and connected with an upper die handle, and a lower extrusion head is arranged in the perpendicular cylindrical hole of the lower extrusion die, and connected with a lower die handle. The forming die can solve the problems that in the prior art, product accuracy is poor, the die manufacturing cost is high, and the working environment is poor.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a loader piston rod molding die. Background technique [0002] The working cylinder of the excavator is an important part of the engineering excavator. Under the alternating action of tensile stress and compressive stress, the piston rod of the cylinder will be subjected to a large impact load, and due to the heat generated by the close contact and friction with the packing, the piston rod will The temperature itself rises. Such working conditions require that the piston rod blank must be a forging with high machining accuracy and strong comprehensive mechanical properties. The hardness of the contact part with the filler is even higher at the working temperature; In the past, the forgings generally adopt the traditional die forging hammer forging process. The basic process is heating in the heating furnace, air hammer blank making, die forging hammer forming and punching trimm...
