Stamping tuagyog cov txheej txheem tshwj xeeb rau kev ua cov ntaub ntawv rau hauv ib feem (lossis cov khoom tiav ib nrab) hauvstamping ua.
Kev faib tawm raws li qhov txheej txheem:xuas nrig ntaus tuag, khoov tuag, nqus nqus tuag, sib sau tuag, lwm yam
Kev faib tawm raws li qib kev sib xyaw ua ke: txheej txheem ib leeg tuag, sib xyaw tuag, vam meej tuag.
a) Kev tuag tuag b) Kev sib sib zog nqus tuag c) Flanging tuag d) nthuav dav tuag
Peb lub ntsiab lus ntawm kev tsim khoom thooj ntawv: txheej txheem tsim nyog tsim nyog, tuag siab dua, thiab cov cuab yeej siv khoom siv tau zoo
Qhov tsis xws luag thiab ua rau thwj cim
1. Cov khoom poob, xuas nrig ntaus, txiav
Defects: excessive burr, deformation, surface scratches, size discrepancies, less holes, lwm yam
(1) Excessive burr → Excessive or small clearance of cam and concave die; wear of edge; poor guiding accuracy; different location of cam and concave die, lwm yam
(2) Deformation → hole distance is too small; the press plate and concave die surface are not well matched; gap is too large, lwm yam
(3) Surface scratching → operation with dragging, pulling, lwm yam; plate material is scratched in the shearing process, lwm yam
(4) Size does not match → the feeding is not in place; the positioning device is damaged or loose, position tampering, lwm yam
(5) Less hole → punch broken; punch length is not enough, lwm yam
Qhov tsis zoo ntawm qhov poob, xuas nrig thiab txiav cov khoom yooj yim
2. Kos duab
Qhov tsis zoo ntawm qhov chaw ntawm cov khoom kos
3. Flanging
Defect: Flanged edge is not vertical, flanged edge height is not consistent, flanged edge is stretched, flanged edge is cracked, lwm yam
(1) Flanging tsis yog ntsug the † 'qhov sib txawv nruab nrab ntawm lub puab tsaig thiab concave tuag yog loj heev.
(2) Flanging qhov siab tsis sib xws † † 'kev tshem tawm tsis sib luag ntawm cov convex thiab concave tuag; qhov chaw tsis raug; qhov loj tsis raug ntawm qhov poob.
(3) Flanged ntug rub edge † 'scarred ntug; impurities nyob rau saum npoo ntawm ib feem; qis heev hardness ntawm ntug.
(4) Flanged ntug tawg † † 'burr loj thaum txiav; qhov sib txawv me me ntawm cov kab mob convex thiab concave tuag; hloov pauv sai ntawm cov duab ntawm ntug flanged.
Cov khoom flanged yog qhov ua rau qhov tsis xws luag
4. Khoov
Defects: bending angle failure, bending edge rupture, bending R angle at the step, lwm yam
(1) khoov lub kaum ntse ntse tsis ua haujlwm the the qhov sib txawv nruab nrab ntawm lub puab tsaig thiab lub ntsej muag tuag yog loj dhau, lub ntsej muag thiab lub ntsej muag tuag nrog lub kaum ntse ntse tsis sib xws nrog cov tuab ntawm cov khoom siv phaj.
(2) Khoov ntug tawg † † 'me me convex thiab concave tuag clearance; dabtsi yog khoov lub kaum me me; xuas nrig ntaus loj heev thiab nrawm heev; phaj khoom yog tawv.
(3) Khoov kaum sab xis R nrog cov kauj ruam con † 'convex thiab concave tuag dabtsi yog khoov lub kaum sab xis loj heev; sab nrauv R sab loj heev; dabtsi yog khoov zog me me.
