Double-acting forging tool for all-fiber crankshafts and forging method thereof

Abstract

A double-acting forging tool for all-fiber crankshafts comprises a base, upper die block fixing plates, lower die block fixing plates, a convex die, upper die blocks and lower die blocks. The base is fixedly arranged on a work table. The upper die block fixing plates comprise the upper left die block fixing plate and the upper right die block fixing plate and are movably connected with an upper die frame through connecting rods and pin shafts. The lower die block fixing plates comprise the lower left die block fixing plate and the lower right die block fixing plate and are movably connected with the upper die block fixing plates through square keys. The convex die is connected with a middle punching cylinder of a double-acting hydraulic machine. The upper die blocks comprise the upper left die block and the upper right die block. The lower die blocks comprise the lower left die block and the lower right die block. A die cavity is formed between the upper die blocks and the lower die blocks. A forging method of the double-acting forging tool for the all-fiber crankshafts is adopted, the upsetting speed and the bending speed are regulated by driving a movable cross beam and the punching cylinder through a die closing cylinder of the double-acting hydraulic machine, and therefore speed regulation is easy. In addition, the tool is simple in structure and convenient to assemble and disassemble, volume production can be easily achieved, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a tool for double-action forging of an all-fiber crankshaft and a forging method thereof. Background technique [0002] Forging production is widely used in machinery, metallurgy, shipbuilding, aerospace and many other technical fields, and occupies a very important position in the national economy. The production capacity and technology of forging is an important symbol to measure the development level of a country's equipment manufacturing industry. In particular, the development of full-fiber forging has the characteristics of good mechanical properties, high material utilization rate, and high production efficiency, so that forging production can better meet the needs of the development of various industries in the national economy and national defense construction, and has broad development prospects. [0003] The crankshaft is one of the important parts of the internal com...

AI Technical Summary

Problems solved by technology

[0006] The present invention is aimed at the prior art, the traditional free forging hydraulic press can only move in the vertical direction, the adjustment of the upsetting speed and the bending speed can only be completed by the mold itself, which makes the adjustment extremely difficult, which in turn makes the mold complicated and the manufacturing cost Improvement, low production efficiency and other defects provide a tooling for double-action forging method of full-fiber crankshaft
