夾片沖壓工藝及模具設(shè)計(jì)
摘 要
闡述了沖孔、落料復(fù)合模、壓彎模具的結(jié)構(gòu)設(shè)計(jì)及工作原理。通過(guò)工藝分析，在沖壓材料厚度較薄的小型彎曲件時(shí)，采用沖孔、落料、彎曲復(fù)合模比采用連續(xù)或級(jí)進(jìn)模簡(jiǎn)單。通過(guò)沖裁力、頂件力、卸料力等計(jì)算，確定模具類(lèi)型。該模具采用后側(cè)導(dǎo)柱模架結(jié)構(gòu)形式。廢料從凸凹模和下底座中所開(kāi)的槽中排出。本模具性能可靠，運(yùn)行平穩(wěn)，能夠適應(yīng)大批量生產(chǎn)要求，提高了產(chǎn)品質(zhì)量和生產(chǎn)效率，降低勞動(dòng)強(qiáng)度和生產(chǎn)成本。

Clamping Sheet Stamping Process and Die Design
Abstract
Expounded punching, blanking, bending modulus of the composite structure design and principle. Process analysis by the stamping of thinner material thickness small curved pieces, will use the punching, blanking, flexural modulus composites than continuous or Progressive Die simple. Punching through, the top pieces, such as the discharge of calculation to determine the type mold. The posterior mold using derivative-scale structures form. Waste from the punch and die and the base under which opened the tank discharges. The mold reliable, stable operation to adapt to the requirements of large-scale production, improve product quality and production efficiency. reduce labor intensity and the cost of production.
