Connecting rod automatic roll forging system

Abstract

The invention provides a connecting rod automatic roll forging system. The connecting rod automatic roll forging system comprises a heating furnace, a roll forging device, a feeding manipulator and ataking manipulator; the heating furnace is positioned above the roll forging device; a slide way is formed in a discharge port of the heating furnace; the feeding manipulator is positioned between thebottom of the slide way and a feed port of the roll forging device; and the taking manipulator is positioned at the other end of the roll forging device. In the roll forging device, an upper arc extrusion mold and a lower arc extrusion mold are arranged in parallel, and are driven to rotate by a driving device; and molding cavities are formed in the surfaces of the upper arc extrusion mold and the lower arc extrusion mold. The heating furnace is arranged above the roll forging device, and is connected through the slide way, so that the workpiece feeding speed is accelerated; and through optimization of the structure of the feeding manipulator, the dependence on the part machining precision can be reduced, the influence on parts by the temperature change is reduced, and the service life ofthe feeding manipulator under high-temperature working condition is prolonged.

Description

technical field [0001] The invention relates to the field of automobile connecting rod processing, in particular to an automatic rolling forging system for connecting rods. Background technique [0002] The structure of the roll forging system in the prior art can be found in JP 2006-297447. The heated workpiece is transported to two pressure rollers by a manipulator, and the workpiece is subjected to rolling forging processing. The initial forging temperature of the workpiece is usually required to be between 1050-1100 °C, and the cooling speed of the workpiece in the air is very fast, and the high heating temperature will affect the quality of the finished product of the workpiece. How to increase the conveying speed of workpieces is a technical problem existing in the prior art. [0003] Due to the different workpieces, the position of the reclaiming manipulator needs to be adjustable, but the cost of adding additional actions to the manipulator is high, and it is necess...

Problems solved by technology

[0003] Due to the different workpieces, the position of the reclaiming manipulator needs to be adjustable, but the cost of adding additional actions to the manipulator is high, and the cost of adjusting the position of the reclaiming manipulator needs to be reduced

[0004] The feeding manipulator in the prior art usually uses electromagnets or hydraulic cylinders to drive the opening and closing. Due to the high temperature of the workpiece, some parts in the feeding manipulator are vulnerable parts, such as slide rails and hydraulic cylinders. easily damaged
