鋁板發(fā)生脆脆的響聲是什么因素?

一、關(guān)于鋁板因分流筋調(diào)集不良構(gòu)成的功能降低應(yīng)適當(dāng)增加筋與外外表、筋與筋匯流處的長度,或許增大緊縮比來處理,模頭壓力的改動(dòng)能夠通過改動(dòng)模頭平直段長度來調(diào)整流料阻力。
1. As for the reduction of the function of the aluminum sheet due to the poor mobilization of shunting bars, the length of the bars and the outer appearance, the confluence of the bars and bars should be increased appropriately. Perhaps the shrinkage ratio should be increased to deal with it. The change of the die pressure can adjust the flow resistance by changing the length of the flat section of the die head.
在模具規(guī)劃階段可選擇不一樣的緊縮比來改動(dòng)擠出壓力,但有必要注意機(jī)頭緊縮比要與擠出機(jī)螺桿的緊縮比相適應(yīng);還能夠通過改動(dòng)配方,調(diào)整擠出工藝參數(shù),增加多孔板來改動(dòng)熔體壓力的巨細(xì).
In the stage of die planning, different shrinkage ratios can be chosen to change the extrusion pressure, but it is necessary to pay attention to that the head shrinkage ratio is compatible with the screw shrinkage ratio of the extruder, and the melt pressure can be changed by changing the formula, adjusting the extrusion process parameters and increasing the porous plate.
二、口模出料不均勻,構(gòu)成型材壁厚薄不一致,或許密實(shí)度不一致.這也就構(gòu)成了型材兩個(gè)面之間的力學(xué)功能上的不同,至于壁薄等非標(biāo)型材這兒就不再多說.
Secondly, the uneven discharge of the die, the inconsistent thickness of the wall and the inconsistent density of the profiles, may be inconsistent. This also constitutes the difference of the mechanical function between the two surfaces of the profiles. As for the non-standard profiles such as the wall thickness, there is no more to say here.
三、口模截面規(guī)劃不合理,尤其是內(nèi)筋的分布和交界面視點(diǎn)的處理.這樣會(huì)構(gòu)成應(yīng)力會(huì)合表象存在,需要改進(jìn)規(guī)劃和消除交界面處的直角和銳角.
Thirdly, the section planning of die is unreasonable, especially the distribution of internal reinforcement and the treatment of interface viewpoint. This will constitute the appearance of stress convergence. It is necessary to improve the planning and eliminate the right and acute angles at the interface.


四、定型模的冷卻速率.冷卻水溫往往沒有導(dǎo)致滿足的重視,冷卻水的作用是將型材拉伸的大分子鏈及時(shí)冷卻定型,到達(dá)運(yùn)用意圖.
4. Cooling rate of profiling die. Cooling water temperature often does not lead to satisfactory attention. The function of cooling water is to cool the macromolecular chain stretched by profiles in time to reach the purpose of application.
五、模頭壓力缺乏.模頭處壓力巨細(xì)是直承受模具的緊縮比,特別是模具平直段的長度來抉擇的.模頭的緊縮比太小或平直段太短都會(huì)構(gòu)成制品不細(xì)密,影響物理功能.
Fifth, the die pressure is insufficient. The pressure at the die head is determined by the contraction ratio directly withstanding the die, especially the length of the straight section of the die. Too small the contraction ratio of the die or too short the straight section will constitute the product not compact, affecting the physical function.
