Benang pengikat mekanikal, tidak kira sama ada ia a\u00a0bolt berkepala<\/u>,\u00a0joran<\/u>, atau\u00a0kedai dalam<\/u>, boleh dihasilkan sama ada dengan memotong atau menggulung. Perbezaan, salah tanggapan, kelebihan, dan keburukan setiap kaedah diterangkan di bawah.<\/p>\n

Benang Bergulung<\/b><\/strong><\/h3>\n

Benang gulung ialah satu proses di mana keluli diekstrusi untuk membentuk bahagian berulir pengikat, dan bukannya ditanggalkan seperti dalam benang yang dipotong. Dalam proses ini, bolt dihasilkan daripada bar bulat diameter yang dikurangkan. Contohnya, bolt berdiameter 1\u2033 dihasilkan daripada bar bulat berdiameter .912\u2033. Bahan \"diameter pic\" ini adalah lebih kurang titik tengah antara diameter utama (puncak) dan diameter kecil (lembah) benang. Bolt \"digulung\" melalui satu set dadu benang yang menyesarkan keluli dan membentuk benang. Hasil akhirnya ialah pengikat dengan bahagian berulir diameter penuh 1\u2033 tetapi diameter badan berkurangan (.912). Penggulungan benang adalah proses yang sangat cekap dan selalunya menghasilkan penjimatan kos yang ketara. Oleh itu, Portland Bolt akan melancarkan benang apabila boleh.<\/p>\n

 <\/p>\n

Secara teknikal, sebarang spesifikasi kecuali bolt struktur A325 dan A490 boleh dihasilkan dengan badan yang dikurangkan dan benang bergulung.<\/p>\n

 <\/p>\n

Bolt dengan badan kecil akan lebih lemah daripada bolt dengan badan bersaiz penuh.<\/p>\n

Kawasan paling lemah dari mana-mana pengikat mekanikal ialah diameter kecil benang. Oleh kerana dimensi benang bagi benang potong dan pengikat benang bergulung adalah sama, sama sekali tidak ada perbezaan dalam kekuatan. Seseorang sebenarnya boleh berhujah bahawa pengerasan kerja yang berlaku semasa proses benang gulungan malah boleh menjadikan pengikat dengan benang bergulung lebih kuat. Selain itu, benang potong mengganggu struktur butiran semula jadi bar bulat manakala benang gulung mengubahnya. Orang boleh sekali lagi berhujah bahawa memotong ke dalam butiran bar bulat apabila memotong benang boleh menghasilkan benang yang mempunyai integriti struktur yang kurang daripada bahagian yang telah digulung berulir.<\/p>\n

Kelebihan Roll Threading<\/i><\/em><\/p>\n

    \n
  1. Masa buruh yang lebih singkat bermakna kos yang lebih rendah.<\/li>\n
  2. Oleh kerana bolt berulir gulung mempunyai diameter badan yang lebih kecil, beratnya kurang daripada badan penuh Pengurangan berat ini mengurangkan kos keluli, galvanizing, rawatan haba, penyaduran, pengangkutan dan sebarang kos lain yang berkaitan dengan pengikat yang berdasarkan berat.<\/li>\n
  3. Kerja sejuk menjadikan benang lebih tahan terhadap kerosakan semasa pengendalian.<\/li>\n
  4. Benang yang digulung selalunya lebih licin disebabkan oleh kesan penyinaran operasi guling.<\/li>\n<\/ol>\n

    \u00a0<\/i><\/em><\/p>\n

    Kelemahan Roll Threading<\/i><\/em><\/p>\n

      \n
    1. Ketersediaan bar bulat diameter padang adalah terhad untuk gred bahan tertentu.<\/li>\n<\/ol>\n

      \u00a0<\/i><\/em><\/p>\n

      \u00a0<\/i><\/em><\/p>\n

      Potong Benang<\/b><\/strong><\/h3>\n

      Benang potong ialah proses di mana keluli dipotong, atau dikeluarkan secara fizikal, daripada bar keluli bulat untuk membentuk benang. Sebagai contoh, bolt berdiameter 1\u2033, dihasilkan dengan memotong benang ke dalam badan bolt berdiameter 1\u2033 penuh.<\/p>\n

      Kelebihan Cut Threading<\/i><\/em><\/p>\n

        \n
      1. Beberapa had berkenaan dengan diameter dan panjang benang.<\/li>\n
      2. Semua spesifikasi boleh dibuat dengan benang potong.<\/li>\n<\/ol>\n

         <\/p>\n

        Kelemahan Cut Threading<\/i><\/em><\/p>\n

        Masa buruh yang lebih lama bermakna kos yang lebih tinggi.<\/p>","protected":false},"excerpt":{"rendered":"
