Manipulator for connecting rod automatic roll forging

Abstract

The invention provides a manipulator for connecting rod automatic roll forging. At least two jaws are hinged with a jaw base positioned on the inner side; jaw rods are arranged at the tail ends of thejaws; the sides, near the axes, of the jaw rods are inclined surfaces; manipulator slide blocks are arranged between the jaw rods, and are contacted with the inclined surfaces; the manipulator slideblocks are connected with an opening and closing hydraulic cylinder fixedly arranged at the tail end of the jaw base; and at least one tension spring is arranged between the jaw rods. Through optimalstructural design of a feeding manipulator, the dependence on the manipulator part machining precision can be reduced, the influence on parts by the temperature change is reduced, in particular, the influence on quick-wear parts as hydraulic cylinders and guide rails can be reduced, and the service life of the feeding manipulator under the working condition of high temperature is prolonged.

Description

technical field [0001] The invention relates to the field of automobile connecting rod processing, in particular to a manipulator for automatic roll forging of 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. [0003] 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. easil...

AI Technical Summary

Problems solved by technology

The initial forging temperature of the workpiece is usually required to be between 1050-1100 ° C, and the cooling rate 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

[0003] 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

[0004] 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
