Abstract

A stretch force controllable hand operated hydraulic pull tool use as the attachment of machine-tool for applying a stretch force to workpiece is disclosed. It features the combination of mechanical advancing with hydraulic loading.

Description

technical field [0001] The present invention relates to a fixture, especially a kind of machine tool fixture that is used to apply a certain tension force to a clamped workpiece in mechanical processing so as to achieve the purpose of changing the mechanical properties of the workpiece through stress recovery after processing, specifically a A kind of tensile force controllable manual hydraulic puller. Background technique [0002] In order to improve the fatigue performance of mechanical parts, it has been found that applying a certain tension to the parts during the processing of the parts has a unique effect. Tensile force, and then the workpiece is cut under the action of the tensile force, and the tensile load is removed from the workpiece after the processing is completed, so that the residual stress on the processed surface is redistributed, so as to obtain a satisfactory surface residual compressive stress, And to achieve the control of residual stress level. [00...
