Watch dial plate convex punching processing technology

Abstract

The invention discloses a watch dial plate convex punching processing technology which specifically comprises the following steps: 1, blanking and blank making: punching and forming a brass plate by using a blank punching die to make a dial plate blank; 2, electroplating ground color: electroplating the dial plate blank obtained by blanking and blank making in the step 1; 3, convex punching: punching a protruded hour hand nail on the dial plate blank obtained in the step 2; 4, paint spraying: performing paint spraying operation on the dial plate blank punched with the protruding hour hand nailin the step 3; 5, grinding: grinding the hour hand nail by adopting a plane grinding machine so that the hour hand nail is highlighted; 6, cutting the protruding positions of the batch nails and thehour nails to form shapes and patterns; and 7, electroplating the hour hand pin: electroplating the hour hand pin on the dial plate blank with the split patterns; by stamping the dial plate blank, thedial plate shading and the hour hand pin are integrally formed, the cost is saved, the hour hand pin cannot fall off, the processing procedures are reduced, the process is simple and reliable, and the service life of the watch is longer.

Description

technical field [0001] The invention belongs to the technical field of watch processing, in particular, the invention relates to a watch dial embossing processing technology. Background technique [0002] At present, the processing technology of the hour hand nail on the dial blank of the watch is as follows: figure 1 , figure 2 As shown, the hour hand nail 2 is first cut by a diamond knife, and the rear of the hour hand nail 2 is provided with a convex point 20, the dial blank 1 is drilled with a small hole 10 for installing the hour hand nail 2, and the convex point on the hour hand nail 2 is drilled. 20 is stuck in the small hole 10 on the dial blank 1, then glue is dispensed on the back of the dial blank 1, and the hour hand nail 2 is fixed on the dial blank 1. [0003] First of all, the traditional craft needs to drill small holes on the dial blank, which increases the process; secondly, the hour hand nails are very small, and young people with good eyesight need to ...

AI Technical Summary

Problems solved by technology

[0003] First of all, the traditional craft needs to drill small holes on the dial blank, which increases the process; secondly, the hour hand nails are very small, and young people with good eyesight need to be very careful to install the hour hand nails. Because the hour hand nails are small, the operation Difficult, and the binding efficiency is very low; finally, with the increase of the service life of the watch, the glue fixing the hour hand nail is easy to age, making the hour hand nail fall off and affecting the operation of the pointer, which directly affects the service life of the watch
