Abstract

The present invention belongs to the field of hydraulic machinery, and is one hydraulic press specially for bending and upsetting crankshaft. Technologically, the hydraulic press features the energizing arm levers installed symmetrically below sides of the movable cross beam, swinging block type mold locking devices installed symmetrically on two sides of the upper and the lower bending molds, and the hollow plungers inside the movable cylinders installed oppositely below the movable work table. The hydraulic press may upset smooth rod directly and has high shaping precision, less allowance, simplified forging process, saving in noble metal material, short machining period and other advantages.

Description

technical field [0001] The invention belongs to the field of hydraulic machines, in particular to a special hydraulic machine for crankshaft bending and upsetting. Background technique [0002] With the rapid development of my country's national economy, various motor vehicles need to be continuously developed to meet the needs of my country's engineering construction. Crankshaft, as an important moving part of internal combustion engine, especially full-fiber forging of large multi-turn crankshaft is an important link in the development of various internal combustion engines. So far, the upsetting of large multi-turn crankshafts in my country has been performed on large hydraulic presses with additional bending upsetting dies. The existing problems are: 1. The process is complicated, the cost is high, the energy waste is large, the efficiency is low, the yield is low, and the precision is poor; Firstly, the corresponding positioning groove is processed, which destroys part...
