Kutsika kunofandiwo akakosha ekugadzirisa michina yekugadzirisa zvinhu muzvikamu (kana semi-apedza zvigadzirwa) mukutsika kugadzira.
Kupatsanura zvinoenderana nemhando yeichi chiitiko:chibhakera vanofa, vakafugama vanofa, zvakadzama mufanidzo vanofa, anoumba vanofa, nezvimwe.
Kupatsanura zvinoenderana nedanho rekuita musanganiswa: imwechete maitiro kufa, mukomboni kufa, kufambira mberi kufa.

a) Kuumba kufa b) Kudhirowa kwakadzika kufa c) Kufamba kufa d) Kuwedzera kufa

Izvo zvinhu zvitatu zvekutsika kugadzirwa: zvine musoro kutsika maitiro, epamberi kufa, uye inoshanda yekutsika michina
Zvakajairika kutadza uye zvinokonzera kutsika
1. Kudonha zvinhu, kubaya, kugera
Defects: excessive burr, deformation, surface scratches, size discrepancies, less holes, nezvimwe.
(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, nezvimwe.
(2) Deformation → hole distance is too small; the press plate and concave die surface are not well matched; gap is too large, nezvimwe.
(3) Surface scratching → operation with dragging, pulling, nezvimwe.; plate material is scratched in the shearing process, nezvimwe.
(4) Size does not match → the feeding is not in place; the positioning device is damaged or loose, position tampering, nezvimwe.
(5) Less hole → punch broken; punch length is not enough, nezvimwe.

Inotadza nzvimbo yekudonha, punch uye trim zvigadzirwa zviri nyore

2.Draw

Nzvimbo isina kukwana-yakajairika yezvigadzirwa zvakavezwa

3. Kufamba
Defect: Flanged edge is not vertical, flanged edge height is not consistent, flanged edge is stretched, flanged edge is cracked, nezvimwe.
(1) Flanging haina kutwasuka â † 'mukaha pakati peiyo convex uye concave kufa wakanyanya.
(2) Kukwidziridzwa kwekukwirira kusaenzana â † ’isina kufanira kubviswa kwe convex uye concave kufa; chinzvimbo chisina kukodzera; saizi isiriyo yezvikamu zvakadonha.
(3) Flanged pamupendero kudhonza â † 'mavanga kumucheto; kusvibiswa pamusoro pechikamu chechikamu; yakanyanya kuomarara kuoma kwemupendero.
(4) Flanged kumucheto kutsemuka â † 'hombe burr kana ichicheka; yakanyanya kuderera musiyano pakati pe convex uye concave kufa; shanduko yechimbichimbi muchimiro pamupendero weflanged.

Flanged zvigadzirwa zvinowanzoitika kune hurema nzvimbo

4. Kukotama
Defects: bending angle failure, bending edge rupture, bending R angle at the step, nezvimwe.
(1) kukotamisa kona kutadza â † 'mukaha uripo pakati peiyo convex uye concave kufa wakanyanya kukura, iyo convex uye concave inofa nekona haifanane nehupamhi hweplate zvinhu.
(2) Kukotama kumucheto kutsemuka â † 'diki kwazvo convex uye concave kufa clearance; vakafugama angled iduku kwazvo; kubaya simba kwakanyanya uye nekukurumidza; ndiro zvinhu zvakaoma.
(3) Kukotama R kona nematanho â † ’convex uye concave kufa kukotamisa angle kwakanyanya; yekunze R angle yakanyanya kukura; kukotama simba iduku kwazvo.
