Abstract

The invention discloses an electrical pulse machining method for a pipe bending mold, and relates to the technical field of mold machining. The electrical pulse machining method for the pipe bending mold comprises the following steps of 1 mold pretreating, specifically, a mold blank is clamped on a CNC machining center workbench, milling rough machining is conducted, and preliminary molding of mold cavities of a fixed mold plate and a movable mold plate of the mold is completed; and 2 electrode manufacturing, specifically, a mold drawing is analyzed, the electrode size is determined accordingto the mold cavity labeled size, and two U-shaped electrodes with the same size parameters are manufactured and used for machining the mold cavities of the fixed mold plate and the movable mold plateof the mold. According to the electrical pulse machining method for the pipe bending mold, through improvement on electrode electrosparking and the technology method, the U-shaped electrodes are designed to achieve one-time molding of the mold cavities, the electrodes do not need to be replaced, the production period is greatly shortened, the technological steps are simple, and the machining precision of the pipe bending mold can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of die processing, and in particular relates to an electric pulse processing method for a pipe bending die. Background technique [0002] The principle of EDM machining is that the pulse current applied to the electrode generates high temperature to melt, oxidize and corrode the surface of the metal workpiece. The characteristic of the EDM mold is to accurately copy the shape of the tool electrode on the workpiece (mold). Therefore, the electrode is one of the indispensable tools in EDM. The reasonable design and manufacture of the electrode is closely related to the machining accuracy of the mold hole or cavity. [0003] At present, the cavity processing of pipe bending molds generally adopts the method of milling by machining center or grinding by forming grinding wheel, and the processing accuracy is relatively low. However, the existing EDM lacks a relatively complete processing method, and the processi...
