The invention relates to a heavy-duty isothermal forging hydraulic press, which comprises an upper transverse beam, a lower transverse beam, upright posts, a main cylinder, side cylinders and a slide block, wherein an upper baseplate is fixed on the lower plane of the slide block; and a movable workbench is arranged on the lower transverse beam. The heavy-duty isothermal forging hydraulic press is characterized in that the upper transverse beam and the lower transverse beam form a combined beam body structure; leveling cylinders are fixed on the four corners of the upper end of the upper transverse beam and the upper end of the lower transverse beam; each leveling cylinder is provided with an independent leveling control system; an upper knock-out device is arranged on the slide block; movable workbench positioning mechanisms are arranged on the lower part of the movable workbench body and in the lower transverse beam; and the movable workbench body is further provided with a movable workbench clamping device. The heavy-duty isothermal forging hydraulic press is characterized in that a combined transverse beam is light in weight and is convenient to transport and produce, and the manufacturing cost can be reduced; a leveling effect is achieved via the leveling cylinders, the leveling response time is shortened, and energy is saved greatly; through the upper knock-out device, successful demolding of workpieces can be realized, and the workpiece forging and pressing quality is ensured; and accurate positioning and stable running of a press workbench can be realized, and the production requirement of forging equipment for heavy-duty aviation forgings is met.

The invention relates to a high-synchronization forging equipment, comprising three T-shaped hammering units with heads facing the center, and a driving device for driving each hammering unit to move to the center or to the outside, and is characterized in that it also includes: The transmission device connecting the driving device and the hammer unit, the transmission device includes two coaxial and integrated gears, one of the two gears is at least matched with one rack, and the other is at least connected with two racks. fit, and each rack is correspondingly connected to one of the hammering units. In the forging equipment of the present invention, three T-shaped hammering units can cooperate with a fixed hammering unit to carry out hammering forging, which is driven by gears and racks. Since the two gears are coaxial and integrated, each The racks can be driven to move synchronously, thereby ensuring that each hammering unit also performs hammering and retreating synchronously, with a simple structure and high synchronization.

The invention relates to a series-parallel forging manipulator which comprises a lifting mechanism, an oscillating mechanism, a buffering mechanism, a clamp, a connecting device and a walking big trolley. The series-parallel forging manipulator is characterized in that the lifting mechanism comprises a front lifting arm, a pair of front suspension rods, a clamp supporting shaft, a pair of front lifting linear drivers, a rear lifting arm, a pitching linear driver, a pair of rear lifting linear drivers and a pair of upper connection rods. The oscillating mechanism comprises a pair of rear side moving linear drivers, a rear sliding rod, a rear sliding sleeve, a front sliding sleeve, a front sliding rod and a pair of front side moving linear drivers. The buffering mechanism comprises a pair of front and rear buffering linear drivers. The clamp and the connecting device comprise a clamp body and a clamp body supporting shaft. The walking big trolley comprises a big trolley frame and four big trolley wheels which are installed and fixed at the bottom of the big trolley frame. The series-parallel forging manipulator has the advantages that the modular design of the series-parallel forging manipulator is achieved, the series-parallel forging manipulator is easy to manufacture, the forging quality of a forge piece is easy to ensure, energy consumption is reduced and the production efficiency is improved.

The invention discloses a technology for forging heavy steel ingots into plates. The technology includes the steps of heating the ton-grade steel ingots in a heating furnace for 14-16 hours with the temperature preserved; carrying out rough forging and returning the steel ingots in the heating furnace for heating after rough forging is completed; forging and drawing plate blanks and returning the steel ingots in the heating furnace for heating; forging and drawing the plate blanks again to meet the requirements of technological sizes and flattening surfaces, wherein the finish forging temperature is 840 DEG C; and placing forged plates into a thermal treatment furnace, heating the plates to 980 DEG C, carrying out normalization after the temperature is preserved for a period of appropriate time, cooling the plates in air, then placing work-pieces into the furnace, heating the work-pieces to 740 DEG C and carrying out air cooling after heat preserving and tempering. The technology has the beneficial effects that deformation of the steel ingots is easy, metal flowing is fast, high temperature diffusion is added in the heating process for removing intragranular segregation and intragranular micro-cracks, the forging quality of the steel ingots is guaranteed, and the grain sizes of the forged plates are uniform.
