2、強化所攻牙的強度。積壓絲攻不會損壞被加工資料的組織纖維，鍍鈦加工廠家故揉捏出來的螺紋強度要比切削絲錐加工出來的螺紋高。 </p> <p> 3、更高的產(chǎn)品合格率。由于揉捏絲攻是無屑加工，加工出來的螺紋精度與絲錐的一致性要比切削絲錐好;而切削絲錐是經(jīng)過切削來完結(jié)，在切削鐵屑過程中，鐵屑或多或少總會存在，使得合格率會低一些。 </p> <p> 4，南山區(qū)精密五金模具加工、絲錐本身強度好。由于積壓絲錐沒有排屑槽，其本身強度較切削絲錐會好許多，南山區(qū)精密五金模具加工，南山區(qū)精密五金模具加工。 </p> <p> 5、更長的運用壽命。由于揉捏絲錐不會發(fā)作切削刃口鈍化、崩刃等問題，正常情況下，其運用壽命是切削絲錐的3～20倍。 </p> <p> <br />

style="text-indent:25px">沖孔模的結(jié)構(gòu)與一般落料模相似。但沖孔模有其自己的特點，特別是沖小孔模具，必須考慮凸模的強度和剛度，以及快速更換凸模的結(jié)構(gòu)。在已成形零件側(cè)壁上沖孔時，要設(shè)計凸模水平運動方向的轉(zhuǎn)換機構(gòu)楔的返回行程運動是靠橡皮或彈簧完成。斜楔的工作角度α以 40°～４５°為宜。40°的斜楔滑塊機構(gòu)的機械效率比較高，45°時滑塊的移動距離與斜楔的行程相等。需較大沖裁力的沖孔件，α可采用 35°，以增大水平推力。此種結(jié)構(gòu)凸模常對稱布置，**適宜壁部對稱孔的沖裁。</p><p

style="text-indent:25px">連續(xù)模是一個產(chǎn)品連續(xù)沖壓的過程，特別是遇到?jīng)_孔及切邊較多的情況，沖壓過程中為避免產(chǎn)品壓傷，及模具的穩(wěn)定性，通常需做防跳廢料結(jié)構(gòu)。主要從以下幾點著手：1.沖頭做成異形，可以增加廢料在刀口上的附著力；2.沖頭加吹氣孔；3.刀口做V型或燕尾卡料形式;4.合理放沖裁間隙，減少跳料;5.模內(nèi)吸廢料裝置。連續(xù)模中的各工序的工件是靠帶料的搭邊余料進行傳遞的，制件一般在***的落料工序完成與帶料分離。這個搭邊稱為連續(xù)模的載體。在連續(xù)模中，常見的載體形式有：邊料載體、中間載體、雙面載體、單邊載體等形式。邊料載體是利用在工件的邊余料上沖出導正孔，以此定位進行拉深、彎曲等成形工序。這種載體設(shè)計簡單、可靠、節(jié)省材料，因此應(yīng)用很廣。中間載體是沿帶料，在工件四周切去大部分材料，只在帶料寬度方向的中部留少許連接材料，這種載體剛性不佳，連續(xù)沖壓穩(wěn)定性不夠好。雙面載體是在帶料的兩側(cè)留少撬材料，載體剛性好不易變形，常用于薄料大進距工件的連續(xù)沖壓。單側(cè)載體只在帶料的單側(cè)留少許材料，這種載體剛性較差，只能用于料厚較大、進距較小的工件的連續(xù)沖壓。南山區(qū)精密五金模具加工</p><p
