Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cold-pressed nut processing technology, and this processing step is comparatively simple, manufactures nut efficiency higher, and prepared product size is stable.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of cold-pressed nut processing technology, comprises following processing step:
1), drawing is formulated: need to formulate drawing according to Assembly of the parts:
2), material selection: according to step 1) in drawing choose pretreated raw material, raw material are the disk material of diameter 16.3mm;
3), material intercept: by step 2) in selected disk material carry out segmentation, be divided into the segment of length 12.5mm, obtain pre-blank;
4), cold-heading molding step: by step 3) in the pre-blank that intercepts be placed on 24B cold headers and carry out cold-heading processing, cold headers adopt seven negative mold and each seven forward and backward bars, seven forward and backward bars are arranged on respectively on slide block, seven negative mold are arranged on respectively on the cavity hole of machine body, the seven backlash rods of knowing clearly are installed respectively, for liftout after negative mold; The front-rear reciprocation movement of slide block has driven pediment stick also to realize and having seesawed, in approaching negative mold, pre-blank is realized to the operation such as shaping and cold-heading hole, the left and right running of pre-blank is to rely on the feeding clamp mechanism of cold headers to complete, after cold-heading molding, obtain blank, blank after moulding is detected, detect qualified blank and continue next-step operation, not qualified blank is scrapped;
5), remove burr step: by step 4) in the qualified blank that obtains carry out deburring, make the smooth outer surface of blank smooth-going;
6), tapping step: by step 5) in the blank that obtains be placed on lathe, carry out tapping with screw tap, after tapping completes, detect, detect after qualified and obtain finished product, not qualified scrap processing;
7), plating step: to step 6) in qualified products carry out electroplating technology, then detect, detect the qualified next-step operation that enters, not qualified carrying out be electroplating operations again;
8), packaging warehouse-in: the product of electroplating after qualified is packed, and then warehouse-in is preserved.
As preferred technical scheme, described step 2) in pre-treatment step comprise that annealing softening processes and surperficial phospholeum processing.
The invention has the beneficial effects as follows: manufacturing process provided by the present invention, the relative prior art of its step, more simple, therefore operation is more simple, do not need comparatively skilled workman can carry out production operation yet, the single product of technique of the present invention manufacture efficiency is higher simultaneously, largely, promote the productivity effect of enterprise, and technique of the present invention is because step is simple, therefore the change in size of obtained product is less, therefore the Product Precision that obtained is higher, and size is comparatively stable, and comprehensive mechanical property is better.
