冷擠壓模具介紹和使用說(shuō)明
我們?cè)谏钪锌偸鞘褂酶鞣N各樣的產(chǎn)品，而這些產(chǎn)品實(shí)際上是由特定的模具模制而成的。而且，不同的產(chǎn)品具有不同的模具。這些模具使用時(shí)非常方便，已經(jīng)形成了一批工業(yè)產(chǎn)品。冷擠壓模具就是這樣一種模具，它使用某種冷擠壓技術(shù)來(lái)制造模具并將其發(fā)送到市場(chǎng)上進(jìn)行銷(xiāo)售。
We always use a variety of products in our lives, and these products are actually molded by a certain mold. Moreover, different products have different molds. These molds are very convenient when used, and have formed a batch of industrial production. The cold extrusion die is such a die, which uses a certain cold pressing technology to make the die and send it to the market for sale.
冷擠壓模的擠壓成型是在強(qiáng)大的三向壓縮應(yīng)力狀態(tài)下完成的。沖頭不僅承受強(qiáng)大的壓縮應(yīng)力，而且還要承受各種不平衡的側(cè)向力，并且力是復(fù)雜的，尤其是在壓力集中在沖頭尺寸變化的地方，容易產(chǎn)生脆性斷裂，但模具可能會(huì)破裂和破裂，并且由于劇烈的金屬流動(dòng)會(huì)嚴(yán)重?fù)p壞型腔。冷擠壓模具的結(jié)構(gòu)尺寸，工藝，模具加工和潤(rùn)滑對(duì)模具的壽命有很大影響，但是首先，我們必須注意材料的選擇和熱處理工藝。
The extrusion molding of the cold extrusion die is completed under a strong three-way compressive stress state. The punch is not only subjected to strong compressive stress, but also subjected to various unbalanced lateral forces, and the force is complex, especially in The stress is concentrated at the place where the size of the punch changes, which is easy to produce brittle fracture, while the die may burst and crack and the mold cavity is severely worn due to the violent metal flow. The structure size, process, mold processing, and lubrication of the cold extrusion die have a great impact on the life of the die, but first, we must pay attention to material selection and heat treatment process.
