手板模型產(chǎn)生變形或是裂紋的補(bǔ)救措施

不管是什么材料制作的手板模型，當(dāng)它超出了一定的使用條件限制，可能就會(huì)出現(xiàn)手板模型變形或是裂紋，那么遇到手板模型產(chǎn)生變形或是裂紋應(yīng)該怎么做?還有沒(méi)有方法可以補(bǔ)救?下面濟(jì)南手板加工廠就來(lái)給大家說(shuō)說(shuō)手板模型產(chǎn)生變形或是裂紋的補(bǔ)救措施，大家可以看看內(nèi)容了解一下。
No matter what kind of material is used for the prototype, when it exceeds certain service conditions, the prototype may be deformed or cracked. What should we do if the prototype is deformed or cracked? Is there any way to remedy it? Next, Jinan Handboard Processing Factory will talk about the remedial measures for the deformation or crack of the handboard model. You can have a look at the contents to understand.
1、手板發(fā)生變形后，其內(nèi)部存在一定的殘余應(yīng)力。在對(duì)手板加工前應(yīng)該應(yīng)力?？梢允褂脩?yīng)力退火和自然時(shí)效來(lái)使內(nèi)部應(yīng)力消失。
1. After the hand board is deformed, there is a certain residual stress in it. The stress shall be relieved before the fabrication of the handboard. Stress annealing and natural aging can be used to eliminate internal stress.
2、手板熱裂紋多數(shù)是由于機(jī)械應(yīng)力造成，是在金屬凝固所造成的裂紋。解決辦法是改良手板結(jié)構(gòu)，使其與金屬接觸的面更少。另外一種辦法是在控制金屬的含硫量而增加金屬的熱脆性。
2. Most of the hot cracks in the hand board are caused by mechanical stress, which is caused by metal solidification. The solution is to improve the structure of the hand board so that it has less contact with the metal. Another method is to increase the thermal brittleness of metals by controlling the sulfur content of metals.
3、手板冷裂紋是在低溫下所產(chǎn)品的裂紋。這是由于手板變形引致的，常常出現(xiàn)在手板受拉伸的地方，冷裂紋一般比較細(xì)小，但這種裂紋是不可逆的缺陷，只能重做。在制作大型而薄的手板時(shí)，常發(fā)生冷裂紋。相似，預(yù)防辦法也是減小內(nèi)部應(yīng)力和控制金屬中磷的含量。
3. The cold crack of the hand board is the crack of the product at low temperature. This is caused by the deformation of the hand board, which often occurs in the place where the hand board is stretched. The cold crack is generally small, but this crack is irreversible and can only be redone. Cold cracks often occur when making large and thin hand boards. Similarly, the preventive measures are to reduce the internal stress and control the phosphorus content in the metal.
可以看出一旦手板模型發(fā)生變形和裂紋，補(bǔ)救措施非常麻煩，甚有些變形和裂紋是無(wú)法補(bǔ)救的，是手板模型的重大缺陷，所以變形和裂紋是以預(yù)防措施為主，盡量避免出現(xiàn)變形和裂紋。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://m.scyyst.com咨詢了解吧！
It can be seen that once the hand model is deformed and cracked, the remedial measures are very troublesome, and even some of the deformations and cracks can not be remedied, which are major defects of the hand model. Therefore, the deformation and cracks are mainly preventive measures to avoid deformation and cracks as much as possible.
