Embodiment Construction

[0014] The present invention relates to a tool suitable for metal liquid die forging on a general-purpose hydraulic press, which is characterized in that the lower oil cylinder of the hydraulic press is used as the power source, and the opening of the horizontal and vertical two-parting surface molds is realized through a mechanical system. action. The closing action of the mold is realized by driving the inclined wedge to press down through the force transmission beam and the pull rod when the lower cylinder returns, forcing the movable module to move to the center under the push of the inclined force; The pull rod makes the wedge rise, and the movable module is separated under the drive of the side of the sliding pin hole on the side plate, so as to realize the mold opening. The specific movement process is as follows: when the plunger rod 10 of the lower oil cylinder 9 returns, the force transmission beam 7 fastened to the plunger pulls down the wedge 4 through the pull rod...

Abstract

The invention relates to a liquid forging device of a multisection mold surface for a universal oil hydraulic press, belonging to the technical field of metal processing and comprising movable modules, upper dies, a concave die insert, oblique wedges, a pull rod, side plates, sliding pins, a supporting block and a force transmission transverse beam, wherein the upper dies are positioned in cavities of the movable modules; the two movable modules are positioned on the supporting block of a workbench of the press and can move along a guiding groove on the supporting block left and right; the force transmission bevels of the left oblique wedge and the right oblique wedge respectively come into tight contact with bevels on the two movable modules; a plunger rod of an oil cylinder under the oil hydraulic press is fastened with the force transmission transverse beam in a hole of the supporting block and is respectively connected with the oblique wedges by the pull rod; the sliding pins on both sides of the movable modules are matched with holes of the sliding pins of the side plates; and the side plates are fastened on both sides of the oblique wedges and are connected with the oblique wedges into a whole. The liquid forging device can realize the liquid forging process of a horizontal mold surface forging and a vertical mold surface forging by the opening and the closing control dies of a lower topping cylinder of the universal oil hydraulic press.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a multi-parting surface liquid die forging device for a general hydraulic press. Background technique [0002] Liquid die forging is a new type of metal forming process between liquid forming and solid forming. The liquid die forging process applies high pressure to the liquid metal poured into the mold to eliminate casting defects when it solidifies. And produce a certain plastic deformation, so as to obtain a method of high-quality parts. It combines the strengths of casting and forging. It not only has the advantages of good liquid metal fluidity, easy filling, simple process and low cost in casting process, but also has the characteristics of good organization and excellent performance of forging process products. Liquid die forging is an advanced process with labor-saving, energy-saving and high material utilization. The mechanical properties of the workpiece are ...
