亚搏全站官方生产作业解析
发布人:管理员   发布时间:2022-5-21
由于放电加工是借助于放电所产生的高温而使模具表面熔化的加工方法,因此,在其加工表面形成白色的放电加工变质层,并产生强大地拉应力,这样,在亚搏全站官方的电加工过程中常出现变形或裂纹等缺陷。

Because EDM is a processing method that melts the die surface with the help of the high temperature generated by discharge, a white EDM metamorphic layer is formed on the machined surface and a strong tensile stress is generated. In this way, defects such as deformation or crack often appear in the EDM process of slope protection die.

我们在采用放电加工的模具,必须先采取相应的预防措施,防止热处理时的过热和脱碳,并进行充分回火以降低或消除残留应力

When using the die of EDM, we must first take corresponding preventive measures to prevent overheating and decarburization during heat treatment, and fully temper to reduce or eliminate the residual stress

为了充分消除淬火时产生的内应力,要进行高温回火。在生产作业过程中,间隔一定时间或生产一定数量的制件后,应对制件进行抽样检查,即进行检查。中间检查的目的是了解亚搏全站官方在使用时的磨损速度,评估磨损速度对模具精度和制件质量的影响情况,以预防不合格品的成批出现。

In order to fully eliminate the internal stress generated during quenching, high temperature tempering shall be carried out. In the process of production, after a certain interval or a certain number of parts are produced, the parts shall be sampled for inspection, that is, inspection. The purpose of intermediate inspection is to understand the wear speed of slope protection mold in use and evaluate the impact of wear speed on mold accuracy and part quality, so as to prevent unqualified products from appearing in batches.

                                 

生产作业终了时,应对最终制造的制件新型检查,同时结合对亚搏全站官方的外观检查,来判断钢模具的磨损程度和有无修理或重磨的必要。

At the end of production, the new type of parts finally manufactured shall be inspected, and the wear degree of steel molds and the necessity of repair or regrinding shall be judged in combination with the appearance inspection of molds.

此外,通过对首件检查和末件检查的结果进行比较,能够测算模具的磨损速度,以便合理安排下一次作业的制件生产批量,避免模具在下次使用时因中途需要重磨或修理而中断作业所造成的损失。

In addition, by comparing the results of the first piece inspection and the last piece inspection, the wear speed of the die can be measured, so as to reasonably arrange the production batch of parts for the next operation and avoid the loss caused by the interruption of the operation due to the need for regrinding or repair during the next use of the die.
