Implementation method for conveniently machining bending and punching test sample of gear steel

Abstract

The invention relates to an implementation method for conveniently machining a bending and punching test sample of a gear steel. The method comprises the following steps of 1, fixing a base to a workbench of a horizontal milling machine; 2, placing the bending and punching test sample to be machined into a bending and punching model hole of the base, wherein bending and punching heads to be milledat the two ends of the bending and punching test sample are exposed out of the model hole; 3, laying a copper sheet on the upper surface of the bending and punching test sample located in the model hole, and locking the bending and punching test sample in the model hole of the base through locking screws; 4, carrying out milling machining on one bending and punching head which is exposed out of one side of the bending and punching test sample; 5, fixing the machined side bending and punching head through a positioning plate; 6, repeating the third step; 7, carrying out milling machining on the other side bending and punching head of the bending and punching test sample; and 8, finishing machining, and taking down the bending and punching test sample. According to the implementation methodfor conveniently machining the bending and punching test sample of the gear steel, operation is simple, convenient and rapid, manufacturing of the test sample can be completed by clamping of two times, the parallelism of the bending and punching test sample is easy to calibrate, the machining efficiency can be improved, and the machining precision of the test sample can be ensured.

Description

technical field [0001] The invention relates to a method for realizing the processing of gear steel bending and punching samples. It belongs to the technical field of mechanical processing. Background technique [0002] The bending punching sample is made according to the requirements of gear steel 15-53, and the bending punching performance of the steel is measured after carburizing, quenching and tempering. At present, most of the traditional ways of processing bending and punching samples in China are wire cutting. The defects of this processing method can be roughly divided into the following three categories: [0003] 1. It is difficult to guarantee the parallelism accuracy of the bending punch of the bending sample, and it cannot meet the testing requirements; [0004] 2. The surface finish of the sample cannot meet the testing requirements; [0005] 3. The sample processing cycle is long, which cannot meet the production demand. [0006] At present, there is no sp...
