Ordinary press machine blocking forging tool set

Abstract

The invention discloses an ordinary press machine blocking forging tool set which comprises a tool set support and a die forging punch penetrating the upper end of the tool set support and being capable of vertically reciprocating. A die assembly mechanism and a lateral pressing mechanism are further arranged on the tool set support, wherein the die assembly mechanism and the lateral pressing mechanism are driven by the die forging punch. Due to the fact that a purely mechanical structure is adopted, and a cone-shaped surface machined on the punch is used for controlling separation and closing of a die, the ordinary press machine blocking forging tool set has the advantages of being capable of simplifying a transmission structure, effectively reducing development cost, solving the technical problems of complex structure and high development cost of a common blocking forging tool set and influences of leakage and temperature on product quality, enlarging application range of blocking forging, effectively reducing forging processes, saving energy, obviously improving utilization of materials, and reducing product cost.

Description

technical field [0001] The invention relates to a closed forging formwork, in particular to a closed forging formwork which can be used in ordinary presses. Background technique [0002] Closed forging can forge hollow forgings with more complex shapes, no burrs, no or small draft angles, so that the forgings can be as close as possible to the shape and size of the parts, thereby significantly improving material utilization, reducing cutting man-hours, and reducing product costs . Generally, closed forging can be formed with only one heating and one equipment stroke, which reduces the forging process, improves production efficiency, saves energy, and improves the surface quality of forgings. [0003] Commonly used block forging mold bases are controlled by hydraulic pressure or pneumatic pressure, and the processing of the mold bases is complicated and costly. The hydraulically controlled forging mold base requires a special cooling system to cool the hydraulic oil, and it...

AI Technical Summary

Problems solved by technology

[0003] Commonly used block forging mold bases are controlled by hydraulic pressure or pneumatic pressure, the processing of mold bases is complicated and the cost is high

The hydraulically controlled forging mold base requires a special cooling system to cool the hydraulic oil, and it is easy to leak, and the pressure of the hydraulic cylinder piston has a great impact on the life of the mold

In recent years, the mold base controlled by air pressure with nitrogen spring has overcome the shortcomings of hydraulic control, but the elastic element is installed in the fuselage part under the workbench, and the assembly space is narrow

Moreover, the pressure of the nitrogen spring is greatly affected by the speed and temperature of the press slider, and the forging pressure is unstable.
