The invention relates to the technical field of mechanical processing, in particular to a method for processing a watch middle frame and the watch middle frame. In the processing method of the watch middle frame of the present invention, a nut part is placed in the fixing hole of the outer frame, and the nut part includes a first nut hole and a second nut hole; the inner frame is injected around the inner side of the outer frame to inject the nut part and the inner frame The middle frame of the watch is obtained as a whole; the first rubber plug is placed in the first nut hole, and the middle frame of the watch is roughly polished; the strap holes are respectively opened on both sides of the watch middle frame; the second rubber plug is placed in the second nut hole Plug, to finely polish the middle frame of the watch; through the above method, the first rubber plug will not be inserted into the second nut hole, and when the strap hole is opened, the first rubber plug in the first nut hole will follow the second nut piece The part corresponding to a nut hole is removed together. After rough grinding, there is no need to take out the first rubber plug, and the second rubber plug placed in the second nut hole before fine grinding can be pulled out after processing, effectively preventing the nut hole from being polished and waxed. clogged.
Description
【Technical field】 [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method of a watch middle frame and a watch middle frame. 【Background technique】 [0002] When the applicant manufactures certain models of watches, it is necessary to set nuts in the strap holes of the middle frame of the watch, and the nuts in the strap holes need to be not connected to metal parts and can withstand a tensile force of more than 15KG. Therefore, in the processing of the above When the watch is in the middle frame, the nut needs to be riveted on the metal outer frame of the watch middle frame. After the inner frame is injected, the first grinding of the watch middle frame, the processing of the strap holes and the second grinding of the watch middle frame are performed in sequence. The wax used can easily get into the nut hole and cause the nut hole to be blocked. In order to prevent the nut hole from being blocked by polishing wax in...
