Hydropress with compound function of isothermal forging and electrode pressing

Abstract

The invention relates to a hydropress with a compound function of isothermal forging and electrode slab pressing, which comprises a combined frame type machine body which is composed of a upper beam, a lower beam and four struts, wherein the upper beam is fixedly provided with a kicker cylinder and a side cylinder; the kicker cylinder and the side cylinder are connected with a slider; and the upper plane of the lower beam is provided with a moveable work platform. The hydropress is characterized in that an upper die mounting die groove is arranged on the lower plane of the slider, and a positioning hole and a screw hole are arranged below the lower plane of the slider; the upper plane of the moveable work platform is provided with a mounting groove for fixing an isothermal forging die anda mounting groove for an electrode slab pressing die corresponding to the slider mounting groove; the rear end of the movable work platform is fixed with a support which is provided with a die pushing cylinder; and the lower beam is internally provided with a workpiece ejecting cylinder. The hydropress has the advantages that the intermediate links between the electrode preparation and the isothermal forging are reduced, the capacity is matched, and the transport cost is reduced and the raw material and energy are saved; and the hydropress is suitable for wire forming and coordination production from titanium raw material to the finished product of titanium isothermal forging of the materials such as high temperature alloy, titanium, zirconium alloy and the like.

Description

technical field [0001] The invention belongs to hydraulic equipment, in particular to a hydraulic machine with composite functions of isothermal forging and pressing electrode blocks. Background technique [0002] At present, with the rapid development of demand for special metals in my country's aerospace, ship and other fields, the extraction of high-purity special metals and the forging of hard-to-deform alloys are very important. After the traditional special alloy electrode block is pressed by a hydraulic press, the workpiece needs to be sent to the electric arc furnace for melting of the alloy ingot, and the melted alloy ingot is then subjected to isothermal forging by an isothermal forging hydraulic press to make a final product. This will not only result in many intermediate links and high transportation costs, but also often produce mismatches in production capacity, which will lead to waste of special metal materials and energy. In addition, due to the poor plasti...

This will not only result in many intermediate links and high transportation costs, but also often produce mismatches in production capacity, which will lead to waste of special metal materials and energy

In addition, due to the poor plasticity, high deformation resistance, narrow forging temperature range, and strict deformation rate requirements of hard-to-deform alloy materials such as high-temperature alloys and titanium alloys, manufacturers need to invest in special isothermal forging equipment to complete the above-mentioned production and processing. Increased production costs for manufacturers
