01開齒

　　01 Open teeth

　　用開齒機將鋁型材上要穿隔熱條的部分滾出齒來，目的就是為了增加型材的粗糙度從而提高復(fù)合后型材的剪切力，相當(dāng)于有一排“牙齒”咬住了隔熱條。

　　Using a gear hobbing machine to roll out the part of the aluminum profile that needs to be fitted with insulation strips, the purpose is to increase the roughness of the profile and improve the shear force of the composite profile, which is equivalent to a row of "teeth" biting the insulation strips.

　　開齒過程中“齒”的深度是關(guān)鍵。開齒深度需在0.6mm左右，齒距1.0mm左右，每個齒肩到肩的距離約0.4mm，齒鋒形狀呈牛角狀

　　The depth of the teeth is crucial during the tooth opening process. The tooth opening depth should be around 0.6mm, the tooth pitch should be around 1.0mm, and the distance from each tooth shoulder to shoulder should be about 0.4mm. The tooth tip shape should be in the shape of a cow horn

　　另外，開齒盤的定位在夾頭槽口間要注意略偏外夾頭，外夾頭上要有深而鋒利的齒紋。

　　In addition, the positioning of the toothed disc between the chuck slots should be slightly offset from the outer chuck, and there should be deep and sharp teeth on the outer chuck.

　　好的開齒能讓型材復(fù)合緊密，如此一來，氣密性、水密性，型材的機械性能自然好。

　　A good tooth opening can make the profile composite tightly, so that the air tightness, water tightness, and mechanical properties of the profile are naturally good.

　　02穿條

　　02 Wearing strips

　　穿條就是將隔熱條穿入已經(jīng)開好齒的上下兩支鋁材槽口中，使三者合為一體。有些企業(yè)會將穿條工序整合在開齒機中，即在開齒的過程中就將隔熱條穿入鋁材中。穿條后隔熱條和鋁材之間沒有緊密結(jié)合，條是可以抽動的。隔熱條由電機帶動的一組齒形輪驅(qū)動向前穿入上下鋁材的槽口中完成穿條，有時候鋁材穿條兩槽口中心距離小于10mm的鋁材，這種情況就很難用穿條機直接穿條，只能人工手動穿條了。

　　Wearing a strip is to insert the insulation strip into the upper and lower aluminum slots that have already been toothed, so that the three are integrated. Some companies will integrate the threading process into the gear cutting machine, that is, threading the insulation strip into the aluminum material during the gear cutting process. After wearing the strip, there is no tight bond between the insulation strip and the aluminum material, and the strip can be pulled. The insulation strip is driven forward by a set of toothed wheels driven by a motor and inserted into the slots of the upper and lower aluminum materials to complete the threading. Sometimes, when the distance between the centers of the two slots of the aluminum material threading strip is less than 10mm, it is difficult to directly thread the strip with a threading machine and can only be manually threaded.

　　03滾壓

　　03 Rolling

　　滾壓就是用三組硬質(zhì)滾壓輪，將穿有隔熱條的鋁合金型材壓合。三組滾壓輪分別起到預(yù)壓、壓緊和校正的作用。

　　Rolling is the process of pressing aluminum alloy profiles with insulation strips together using three sets of hard rolling wheels. The three sets of rolling wheels respectively play the roles of pre pressing, compression, and correction.

　　怎么看滾壓效果好不好呢？內(nèi)夾頭保證隔熱條垂直就位，外夾頭齒紋壓入隔熱條。滾壓合格的型材一定會整體外形良好，氣密性、水密性和機械性能達(dá)標(biāo)

　　How to check if the rolling effect is good or not? The inner clamp ensures that the insulation strip is vertically positioned, while the outer clamp teeth are pressed into the insulation strip. Qualified profiles produced by rolling will definitely have a good overall appearance, and meet the standards for air tightness, water tightness, and mechanical properties

　　04剪切力測試

　　04 Shear force test

　　可能很多人認(rèn)為穿條工藝到上一個步驟就結(jié)束了，No，No，沒通過剪切力測試的隔熱型材就是一盤散沙，不用扒拉兩下就散了。

　　Many people may think that the threading process ends with the previous step. No, no, insulation profiles that fail the shear force test are just a pile of loose sand that doesn't need to be pulled or peeled twice.

　　測試步驟很簡單，給復(fù)合型材縱向上施加不斷增加的力，直到鋁型材與隔熱條之間發(fā)生錯位為止。另外，這項檢測不是測一次就行的，得測試10個100mm的試樣，過程中要注意上下夾塊不能夾到隔熱條。檢測型材剪切力強度，就是檢測隔熱條與鋁型材結(jié)合的強度。國標(biāo)規(guī)定，隔熱型材的縱向抗剪強度特征值應(yīng)該大于24N/mm。

　　The testing procedure is simple, apply increasing force longitudinally to the composite profile until there is a misalignment between the aluminum profile and the insulation strip. In addition, this test is not just a one-time test, 10 100mm samples need to be tested. During the process, it is important to note that the upper and lower clamping blocks cannot clamp onto the insulation strip. Detecting the shear strength of profiles is to measure the strength of the bonding between insulation strips and aluminum profiles. According to national standards, the longitudinal shear strength characteristic value of insulation profiles should be greater than 24N/mm.
