加熱棒-加熱管-電熱管使用-壽命

加熱棒-加熱管電熱管使用-壽命

模具在機械行業中廣泛運用,通常對其使用效率要求極高,加熱棒作為關鍵部件,質量、性能的穩定與否,關系重大。工業使用的模具加熱管在整個電熱管的銷售比例中也占到30%左右的席位。面對著龐大的需求市場,就會出現各種各樣的問題,主要問題還是如何正確的看待模具加熱管在使用過程中發生損壞的問題,這個不但切實的關系到使用者,生產者之間直接的經濟和信譽問題。有必要好好的整理和分析正常模具加熱管容易損壞的幾種原因,加強引進戒。

通過技術員的分析模具加熱棒容易造成損壞的原因主要有以下幾個方面所造成(僅供參考)。

1、模具孔孔徑與模具單頭加熱棒的密合度。 單頭電熱管在使用期間,由于本身加熱迅速散熱條件差,常造成電熱外部不銹鋼管體焦黑、氧化、變形,因而造成內部發熱元件-電熱合金絲(NI80Cr20)因高溫空燒融斷,造成單頭電熱管本身壽命縮短,所以優良的單頭電熱管不但需要生產質量好,更要求模具的材質與加工孔徑(孔徑與管徑越接近越好),適合的孔徑除了方便換單頭電熱管之外,也有利于兩者熱能之間的傳導,因而延長加熱管本身電熱管的使用壽命。

2、加熱管設計時是否考慮工作環境的震動性。在模具單頭加熱管設計生產之前,我們還需要考慮工作環境下的震動性,倘若震動性比較大,我們加熱管中的電熱絲就需要采用鎳鉻絲。

3、工作溫度的控制。在模具單頭加熱管工作的時候,溫度的控制也是至關重要的,溫度一旦控制不住,也會導致加熱管外部不銹鋼管體焦黑、氧化、變形,因而造成內部發熱元件-電熱合金絲因高溫空燒融斷,造成單頭電熱管本身壽命縮短。一般控制為在200-300℃之間。

以上就是我們在設計定制模具和模具使用過程紅得需要注意的幾點,以便延長模具加熱管壽命。其實生活中還有很多工作環境因素等等。望此次模具加熱管容易損壞幾個問題的探討能夠對大家有用,若在電熱管產品、加熱管產品、網帶產品等需要有更多更準確的咨詢.歡迎來電咨詢:0512-57123258

Mould is widely used in the machinery industry, usually on the use efficiency is extremely high, the heating rod as key components, quality, performance is stable or not, the relationship between major. Mould heating industrial pipe used throughout the heating pipe sales ratio has accounted for about 30% of the seats. Facing the huge market demand, will appear a variety of problems, the main problem is how to correctly treat mold heating tube damage problem occurred in the use of the process, this is not only feasible to user, the direct economic and credit problems among the producers. It is necessary to sort out and analyze the normal heating tube mould several reasons easily damaged, strengthening the introduction of ring.
Easily through the analysis of mould heating rod technician of the cause of the damage is mainly in the following areas caused by (for reference only).
1, die diameter and Die single head heating rod adaptation. Single head heating tube during use, because of its rapid heating cooling condition is poor, often cause body charred, oxidation, deformation heating external stainless steel tube, resulting in internal heating element – Electrothermal alloy wire (NI80Cr20) because of the high temperature air burning fuse, resulting in shortened life of single head electric heat pipe itself, so the single head electric excellent tube not only the production of good quality, more requirements of material and processing mould (aperture and aperture diameter of the closer the better), suitable aperture besides convenient for single head electric heat pipe, but also conducive to the conduction of heat between the two, thus prolonging the service life of electric heating pipe heating pipe itself.
Whether to consider the motion of 2 work environment, heating pipe design. Before the single head heating tube mould design and production, we also need to consider the motion of working environment, if the vibration is relatively large, we in the heating pipe heating wire requires the use of nichrome wire.
3, temperature control. When the mould single head heating tube work, the temperature control is also very important, when the temperature can not control, will also lead to external stainless steel heating tube, black oxide, deformation, resulting in internal heating element and the electrothermal alloy wire for high-temperature air burning fuse, resulting in shortened life of single head electric heat pipe itself. The general control in between 200-300 ℃.
The above is what we in the custom design of die and mold using several process red note, in order to prolong die service life of heating pipe. In fact, the life has a lot of work environment factors and so on. At the heating tube mould of easily damaged several problems can be useful to everyone, if the tube products, heating in the electric heating pipe products, network products need to have more accurate advice.
