1、在使用鋁板生產(chǎn)模具的時(shí)候，需要選擇合適的加熱溫度。要嚴(yán)格控制擠壓錠坯的合金成分。目前一般企業(yè)要求鑄錠晶粒度達(dá)到一級(jí)標(biāo)準(zhǔn)，以增強(qiáng)塑性和減少各項(xiàng)異性。
1. When using the aluminum plate to produce the mold, it is necessary to choose the appropriate heating temperature. The alloy components of the extruded ingot must be strictly controlled. At present, the general enterprises require the grain size of ingot to reach the first grade standard, in order to enhance the plasticity and reduce the various heterosexual.
2、鋁板生產(chǎn)模具上機(jī)前工作帶必須經(jīng)過研磨拋光，工作帶一般要求拋光至鏡面。對(duì)模具工作帶的平面度和垂直度裝配前要進(jìn)行檢查。
2. The front work belt of the aluminum sheet production die must be polished and polished, and the working belt is generally required to be polished to the mirror. Check for the flatness and perpendicularity of the die working belt before assembly.
3、鋁板生產(chǎn)模具保溫時(shí)間一般在2-3小時(shí)左右，但不能超過8小時(shí)，否則模具工作帶氮化層硬度會(huì)降低而導(dǎo)致上機(jī)時(shí)不耐磨引起型材表面粗糙，嚴(yán)重的會(huì)引起劃線等缺陷。

3, the aluminum plate production mold holding time is generally about 2-3 hours, but it can not exceed 8 hours, otherwise the mold working nitrided layer hardness will decrease, resulting in the machine wear-resisting, causing rough surface profile, and serious will cause the marking and other defects.
4、進(jìn)行擠壓生產(chǎn)前，需對(duì)型材截面進(jìn)行充分計(jì)算，根據(jù)型材截面的復(fù)雜程度，壁厚大小以及擠壓系數(shù)λ來(lái)確定擠壓機(jī)噸位大小。
4, before extrusion production, we need to fully calculate the cross section of the section, and determine the tonnage size of the extruder according to the complexity of the section section, the thickness of the wall and the extrusion coefficient.
5、鋁板生產(chǎn)模具卸模后，此時(shí)模具溫度在500°C以上，如果立即浸入堿水中，由于堿水溫度要比模具溫度低得多，如果模具溫度下降迅速，模具極易發(fā)生開裂現(xiàn)象。正確方法是等卸模后將模具在空氣中放置到100°-150°C再浸入堿水中。
5, when the aluminum plate production mold is unloaded, the mold temperature will be above 500 degree C. If immersion in alkali water immediately, because the temperature of alkali water is much lower than that of the mold, if the mold temperature drops rapidly, the mold will easily crack. The correct method is to put the mold in the air to 100 -150 C and then immerse in the alkali water after the mold is unloaded.
