Novel electric discharge machining machine tool for heavy-duty tire mold

Abstract

The invention discloses a novel electric discharge machining machine tool for a heavy-duty tire mold. The novel electric discharge machining machine tool comprises a base. A rotation box is arranged on the base. A main shaft in the rotation box is connected with a four-jaw chuck. The face, making contact with the four-jaw chuck, of the rotation box tilts by 15 degrees. A stand column is arranged on the base. An inclined sliding plate capable of moving up and down along a guiding rail face is arranged on the stand column. An included angle formed between the inclined sliding plate and the stand column is 15 degrees. A beam is arranged on the inclined sliding plate, wherein an included angle formed between the stand column and the beam is 15 degrees. The beam can move in the direction perpendicular to the four-jaw chuck. A division rotary table is arranged at the front end of the beam. A discharging machine head is arranged on the division rotary table. The novel electric discharge machining machine tool for the heavy-duty tire mold is simple in clamping, high in rotation precision, free of timing adjustment, reasonable in machining, high in product quality and high in speed, efficiency and precision, and has the adjustable machine head.

Description

technical field [0001] The invention relates to the technical field of electric machining of tire molds, in particular to a novel electric discharge machine tool for heavy tire molds. Background technique [0002] Heavy-duty tire mold EDM machine tool is mainly used for high-precision machining of complex patterns in the heavy-duty tire mold cavity. At present, the tire mold EDM machine has the following defects: a. The rotation adopts a single worm gear mechanism without automatic backlash elimination, and the gap needs to be adjusted regularly, which is easy to produce defective products; b. The four-jaw chuck is installed vertically, which is inconvenient to clamp the workpiece and easy to produce The accident of workpiece falling off occurs; c. The angle of the machine head is fixed, it cannot swing, and it cannot process along the normal direction of the workpiece. d. Due to the heavy weight, the error rate of the existing equipment cannot be repaired. Contents of th...
