- macchina a forbice: usato per tagliare i fogli metallici in contorni dritti della dimensione desiderata per fornire materiale di base per la successiva flessione.
- CNC Punching Machine: punzonatura, scanalatura o taglio di una forma speciale in una piastra di metallo per mezzo di un dado, spesso usato per la flessione.
- Macchina di flessione: Come una delle apparecchiature principali della lamiera, applica la pressione su lamiera attraverso l'idraulica o il monoela a Href = "href =" hretps://jsrpm.com/blog/how-does-fabrication-work " lamiera , Supportando la flessione di una forma a più angolo e complessa.
- stampo piegabile: include stampo superiore e inferiore, determinare l'angolo di flessione, il raggio e la precisione. Common mold types are V-shaped mold, pointy mold, etc., che deve essere selezionato in base allo spessore della piastra e ai requisiti tecnologici.
- Premere MACCHINA : fornisce un'alta pressione di tonnellaggio per lo stretching profondo o la formazione di superficie complessa, comunemente usata nella produzione di componenti strutturali ad alta resistenza come parti di lamiera.
- macchina da taglio laser: Una sorta di apparecchiatura di taglio termico ad alta precisione che può sostituire il taglio tradizionale. È particolarmente adatto per l'elaborazione dei contorni della piastra sagomata e migliora l'efficienza della preparazione del materiale prima della flessione.
- Sistema di programmazione di piegatura CNC: percorsi di flessione e parametri>
- Equipaggiamento di saldatura : come Arc Arc e Spot Wadering Machine, utilizzato per fissare le parti di flessione e migliorare la forza strutturale (come parti della telaio).
Insieme, questi dispositivi coprono l'intero processo dal taglio della lamiera e si forma alla machinatura di precisione, in cui si collega a successivo funzione del prodotto finito.
1. Fabbricazione di lamiera vs. Casting
Vantaggio Confronto:
- Costo e ciclo: L'elaborazione di lamiera non richiede l'apertura di stampo , idoneo per la piccola produzione, a basso costo. Casting requires custom molds that are expensive to start with but Adatto alla produzione di massa (come i corpi dei bloccanti del cilindro del motore).
- Tasso di utilizzo del materiale: lamiera dopo aver tagliato i materiali rimanenti può essere riutilizzato, il tasso di utilizzo di oltre il 90%. Lightweight: la lamiera può essere piegata e allungata per ottenere strutture complesse leggere, come i telai dei droni, mentre le getti sono generalmente in stati più pesanti.
Limitazione:
la lamiera è difficile da elaborare cavità complesse o strutture irregolari e il casting può formare cavità.
Scenari applicabili:
- Seleziona lamiera: prototipazione rapida, peso leggero, personalizzazione batch piccola (come Applicaces e Chassis).
- Selezione di getti: alta resistenza, struttura della cavità complessa (come ingranaggi meccanici, valvole della tubazione, ecc.).
2. Fabbricazione di lamiera vs. saldatura
Vantaggio Confronto:
- Integrazione: la lamiera forma direttamente una struttura tridimensionale (come un telaio del corpo automobilistico) piegando, riducendo i punti di saldatura e aumentando la forza complessiva.
- Controllo di precisione: la macchina di curvatura CNC può ottenere una tolleranza a surfic. Welding is easily affected by operation and needs to be polished in Elaborazione successiva.
- > Efficienza: la lamiera è adatta alla produzione di massa standardizzata, mentre la saldatura è più adatta per la riparazione o il rinforzo parziale delle parti della lamiera.
Limitazioni:
La saldatura può collegare materiali diversi (come metallo e plastica), mentre la lamiera è limitata a fogli di metallo simili.
Scenari applicabili:
- Selezione piastra: produzione standardizzata di parti a piastre (come staffe elettriche, scaffali, ecc.).
- > Scegli la saldatura: difetti di riparazione, collegare materiali diversi o rinforzare temporaneamente (come l'edificio dell'acciaio).
3.Core advantage scene of sheet metal Fabrication
- Iterazione rapida: la fase di sviluppo del nuovo prodotto non richiede investimenti in muffa, accorciando notevolmente il ciclo di ricerca e sviluppo (come la stampa 3D+lamiera di lamiera).
- Design leggero: ottimizzazione del peso strutturale attraverso flessione, stretching e altri processi (ad esempio riduzione aerospica 30%).
- > Produzione su larga scala: l'attrezzatura CNC supporta una capacità di produzione giornaliera di decine di migliaia di pezzi (come le linee di timbratura del telefono cellulare).
- Ambientale Ambiente: il tasso di riciclaggio dei rifiuti supera il 95% e le emissioni di carbonio sono inferiori alle getti (fonte di dati: Rapporto di associazione internazionale per la lavorazione dei metalli).

inizio con fogli grafico a scartamento in lamiera e parametri correlati per fornire una guida di selezione sistematica:1. Chiarisci Requisiti dell'applicazione
- Requisiti funzionali: in base alla capacità di moto, alla resistenza alla corrosione e alla conduttività elettrica del materiale, scegli materiali diversi.
- Limitazioni di processo: per i materiali di piegatura in lamiera complessa, la priorità dovrebbe essere data ai materiali con buona duttilità (ad esempio lamiera di alluminio
| materiale | 16ga （mm） | 20ga （mm） | 24ga （mm） |
| foglio rollato a freddo | 1.5 | 0.9 | 0.6 |
| in lega di alluminio 5052 | 1.6 | 1.0 | 0.7 |
3. Caratteristiche materiali comuni
| type | Advantage | Applicazioni tipiche |
| foglio d'acciaio galvanizzato | Resistenza alla corrosione, basso costo. | box per computer esterno, scatola per elettrodomestici (deve soddisfare gli standard di test di spruzzo salino). |
| lega di magnesio in alluminio | leggero, buona conducibilità. | dissipatori di calore elettronici, componenti aerospaziali (selezionati in base ai requisiti di durezza). |
| acciaio inossidabile | antiossidante, resistente al calore, antibatterico. | attrezzature chimiche e mediche (è necessario bilanciare i costi e i requisiti di igiene). |
4. Adattamento dei parametri di processo
- Processo di curvatura in lamiera: le piastre sottili (ad esempio 24ga) richiedono stampi con colture a V più piccole per prevenire il cracking, mentre le piastre spesse (ad esempio 16Ga) richiedono una pressione aggiuntiva.
- Welding compatibility: Aluminum plates require inert gas protection for welding, and argon arc welding is recommended for stainless steel (parameters need to be adjusted to material thickness).
- Surface treatment: Galvanized sheet metal can be sprayed directly, while aluminum sheet metal require anodic oxidation pretreatment (process cost differences need to be taken into account in selection).

How to replace stainless steel with galvanized sheet metal to achieve the same strength?
1.Choose high-strength alternatives
- High-strength galvanized sheet: Choose high-strength low-alloy steel as the base, its tensile strength can be over 600MPa, close to ordinary stainless steel (such as 304 stainless steel, a tensile strength is about 515MPa).
- Double layer galvanizing process: Aluminum zinc plating is adopted on the surface of cold rolled steel plates to improve corrosion resistance while maintaining the high strength characteristics of substitute material.
2.Sheet metal fabrication technology
- Cold rolling reinforcement: The yield strength of galvanized sheet is increased by cold rolling (When the cold rolling deformation exceeds 30%, the strength can be increased by 20%-30%).
- Annealing control: Use incomplete annealing (such as recrystallization annealing) to balance strength and ductility and avoid excessive softening.
- Surface treatment strengthening: Passivation or phosphorylation of the galvanized layer to reduce the risk of microcracks during sheet metal bending.
3.Structural design
- Ribs/flanges: Design of reinforcement or flange structures in key stress areas of sheet metal parts to enhance bearing capacity through geometric shapes (e.g. car chassis parts).
- Bending angle optimization: Using stair bending (Z bend) instead of right angle bending, scattered stress concentration, improve overall stiffness.
- Curling process: The edges of thin sheets (e.g. 5mm thick galvanized sheet metal with a curl radius ≤1t) are curled to prevent sheet metal bending and enhance bending strength.
4.Welding and connection process
- Resistance welding in place of riveting: On the basis of good galvanized sheet conductivity, spot welding or seam welding can reach more than 80% of the strength of the substrate (welding current needs to be controlled to avoid evaporation of the zinc layer).
- Laser welding: High energy laser welding can reduce the heat effect area, avoid strength attenuation caused by zinc coating melting, and reach joint strength close to stainless steel.
5.Verification and testing
- Tensile test: The yield strength of galvanized sheet ≥355MPa (Equivalent to one-third of the strength of 304 stainless steel).
- Cyclic load test: Simulation of actual working conditions (such as vibration, impact, etc.) to verify that the fatigue life of galvanized sheet metal meets the standards.
- Sheet metal bending rebound compensation: Through die prebending or angle correction, to ensure that the dimensions of the bending accuracy and stainless steel parts.
Key preventive measures
- Avoid excessive bending: Galvanized sheet metal are less malleable than stainless steel and should have a bending radius ≥1.5 times thickness (stainless steel generally ≥1 times).
- corrosion reinforcement: In humid environments, epoxy resin is required to be partially sprayed or coated with an increased thickness (e.g., Dacromet treatment).
