Die forging press crankshaft connecting rod structure and die forging press

Abstract

The crankshaft connecting rod structure comprises a machine body, a crankshaft and a connecting rod, the crankshaft comprises a crankshaft journal, a supporting journal and a fixed-distance journal, and a first copper sleeve, a second copper sleeve, a third copper sleeve and a fourth copper sleeve are arranged on the contact surfaces of the crankshaft journal, the connecting rod and the machine body correspondingly; the first copper sleeve, the second copper sleeve, the third copper sleeve and the fourth copper sleeve are provided with a first oil inlet, a second oil inlet, a third oil inlet and a fourth oil inlet respectively, the outer end face of the first copper sleeve and the outer end face of the second copper sleeve are sealed through sealing structures, and the lower end of the connecting rod is closed and provided with a first oil outlet. The inner end face of the third copper sleeve and the inner end face of the fourth copper sleeve are sealed through sealing structures, a second oil outlet is formed below the third copper sleeve, an axial fixing assembly is arranged at the position, on the right side of the crankshaft, of the fixed-distance journal in a sleeving mode, and a third oil outlet is formed below the axial fixing assembly. The structure provided by the invention has the characteristics of recyclable lubricating oil, good lubricating effect, sanitation, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of forging industrial equipment, and in particular relates to a crankshaft connecting rod structure of a die forging press and a die forging press. Background technique [0002] Presses are widely used equipment in metal forming, and hot die forging presses are forging equipment that realize metal hot blank forming with the help of molds. The traditional hot die forging press is a three-phase asynchronous motor that drives the large flywheel to rotate continuously, and the clutch controls the movement of the crank slider connected to the shaft of the large flywheel. At present, the tonnage of commonly used hot die forging presses is between 500T and 10000T. During the working process of the hot die forging press, the crank slider mechanism drives the upper die base to reciprocate and impacts the lower die base to complete hot forging. [0003] The crankshaft and connecting rod assembly needs to be lubricat...

AI Technical Summary

Problems solved by technology

[0003] The crankshaft and connecting rod assembly needs to be lubricated when the die forging press is running, but in the prior art, grease is often used as the lubricant for the lubrication of the crankshaft and connecting rod assembly of the die forging press, and the oil return method is directly along the circumference of the copper sleeve and Discharged from the end face of the shaft, has no recycling function, cannot be reused, is neither hygienic nor environmentally friendly
