Flowering branch drawing method and mold component for stainless steel handle and press

Abstract

A method for drawing the flowering branch of a lifting handle of a rotary handle of stainless steel and die components comprise manufacturing more than two pairs of drawing dies and manufacturing a flood relief channel at the drawing tusk position of at least one pair of the die; in the process of drawing, a drawing lubricant flows over the drawing die with a workpiece and simultaneously plays the roles of lubrication and continuous temperature reduction. The shapes of the drawing tusks of the invention are the same during a plurality of drawing working procedures; simultaneously the drawing tusks of the invention are matched with drawing canals and drawing guided modes to lead the workpiece not to jitter during the drawing; then a double-polishing cloth wheel is used for deepening into the root of the pattern of the workpiece to polish; thereby the surface of the final product is led to have the advantages of the regular shape and the high finish degree as well as the good quality consistency during batch production.

Description

technical field [0001] The invention relates to a manufacturing process of watch parts, in particular to a process method and equipment for drawing pressed flower branches of watch stainless steel bars. Background technique [0002] In the prior art, most of the tyrants of watches are made of brass, and the tyrants are the rotary handles for watch schooling, and the pressing handles for watch schooling are pressed. The button of the bully is generally made of brass and then plated with chrome. This coating is often very thin. If a person with an acidic physique wears the watch, his sweat will easily peel off the coating and further corrode the push buttons, making the watch as a whole ugly. In order to prevent the push button of the tyrant from being corroded, people naturally think of making the push button of the tyrant with stainless steel. [0003] In the prior art, most of the techniques of making tyrants made of stainless steel are molded. This method is exactly to r...

Problems solved by technology

Does not involve the introduction of how to draw relatively thick stainless steel rods with patterns on the surface

[0005] The prior art shown in Fig. 6, Fig. 7 and Fig. 8 has a simple method of making three sets of drawing dies with gradually enlarged jaws to gradually draw out the stainless steel bars, but the products drawn by this technology, The surface finish is very poor, and the surface shape is stiff, the stainless steel rod is distorted and deformed, and the quality cannot be improved by grinding alone
