Berbanding dengan mesin lentur dan pemotong. Toleransi Mesin Pembentuk Roll akan menjadi agak besar. Tetapi memandangkan kelajuan mesin, pengguna akhir juga akan lebih suka mesin membentuk roll.<\/p>\n

<\/p>\n

Toleransi Keratan Rentas<\/strong><\/h2>\n

Pelanggan, pereka produk dan pereka bentuk gulungan mesti bersetuju dengan tafsiran dimensi dan toleransi yang dinyatakan dalam lukisan sebelum reka bentuk gulungan dimulakan. <\/span>Toleransi produk akan menjejaskan reka bentuk gulungan, bilangan dirian, dan dengan itu kos perkakas. <\/span>\u00a0Sebagai peraturan umum, lebih ketat toleransi produk, lebih banyak bilangan dirian roll membentuk. <\/span>Kepelbagaian keratan rentas dan kombinasi toleransi yang tidak terhingga menjadikannya mustahil untuk meletakkan nilai berangka yang tepat pada peningkatan bilangan hantaran yang diperlukan, tetapi pereka gulungan yang berpengalaman merasakan berapa banyak dirian tambahan untuk mencapai toleransi yang diperlukan.<\/span><\/p>\n

Penyimpangan daripada Toleransi Kelurusan dan Kerataan<\/strong><\/h2>\n

Sifat pembentukan gulungan akan menyebabkan camber, bow, twist, cross-bow, kesan herringbone, tepi, atau gelombang tengah. serta ketidaksempurnaan dalam bahan, peralatan dan persediaan. <\/span>Perkakas mempunyai hebat\u00a0<\/span>pengaruh ke atas tegasan baki, yang mewujudkan sisihan daripada kelurusan dan kerataan. <\/span>Reka bentuk mesin membentuk gulungan yang baik menghapuskan atau meminimumkannya, sementara\u00a0<\/span>reka bentuk yang buruk mencipta atau membesar-besarkan masalah ini.<\/span><\/p>\n

Toleransi Mesin Pembentuk Roll terhadap Lokasi Lubang dan Takik\u00a0<\/strong><\/h2>\n

Pereka bentuk mesin pembentuk gulungan mesti menentukan urutan operasi jika keratan rentas menentukan lubang, takuk, timbul atau perubahan lain pada permukaan jalur. <\/span>Semasa proses membentuk gulungan, bahagian tertentu produk berada di bawah ketegangan, manakala sebahagian yang lain dimampatkan. Reka bentuk mesin membentuk gulungan harus mempengaruhi t<\/span>perbezaan antara panjang keseluruhan bahagian sebelum dan selepas pembentukan gulungan.\u00a0<\/span>Dalam sesetengah kes, pereka bentuk boleh meneruskan dengan pratebuk produk, menggunakan dimensi akhir atau anggaran. <\/span>Berdasarkan ukuran lokasi lubang sebelum dan selepas pembentukan gulungan, pelarasan boleh dibuat dalam corak prapunching. Kadang-kadang, Kadang-kadang, Untuk mewujudkan dimensi prapunching terakhir, pereka bentuk perlu mengulangi beberapa langkah.<\/span>\u00a0<\/span>Walau bagaimanapun, adalah penting untuk menjalankan ujian dengan tekanan gulung yang sama. <\/span>Tekanan besar yang tidak wajar boleh menipiskan bahan dan memanjangkan produk, sekali gus memberikan keputusan ujian palsu pada lokasi lubang.<\/span><\/p>\n

Berbanding dengan panjang jalur sebelum terbentuk. Kedalaman bahagian yang meningkat, hantaran yang lebih sedikit, jejari lentur yang lebih besar, nisbah ketebalan, dan peningkatan yang lebih besar dalam diameter gelendong dirian akan memanjangkan panjang produk. <\/span>Jika nisbah jumlah luas elemen bengkok kepada jumlah luas elemen lurus adalah tinggi, dan bahagian itu dibentuk dengan bilangan hantaran yang mencukupi, maka panjang produk siap akan sama dengan panjang jalur permulaan<\/span><\/p>\n

Toleransi Panjang Mesin Pembentuk Roll<\/strong><\/h2>\n

Kaedah mengukur panjang, sistem pecutan dadu dan akhbar mempunyai pengaruh yang paling besar terhadap toleransi panjang. <\/span>Sebagai tambahan, faktor lain seperti reka bentuk gulungan juga boleh mempengaruhi toleransi panjang. <\/span>Perbezaan kelajuan permukaan pada permukaan pemanduan boleh menyebabkan kelajuan membentuk gulungan tidak sekata. <\/span>Perbezaan besar antara kelajuan permukaan roller atas dan bawah yang dipacu boleh meningkatkan toleransi panjang sebanyak 8 hingga 10 kali ganda.<\/span><\/p>\n
