Alyuminiy plitalarida punchıkığı jarayoni, pushunchin bo'shliqning oqilona sozlanishi mahsulot sifati, hayoti va ishlab chiqarish samaradorligi uchun juda muhimdir. Quyida alyuminiy plitalaridagi batafsil tahlil va takliflar - bu punchning pasayishi:
1. Gapiriqni teshib qo'yishning ta'rifi va ahamiyati mushtning mushtlari va yog 'orasidagi bir tomonlama masofani anglatadi, odatda, materialning qiymati (t) ning foizi sifatida ifodalanadi. Chunki juda kichik yoki juda katta tafovut quyidagi muammolarga olib keladi: materiallar ikki marta qisqaradi, bu material ikki baravar ko'paydi. Juda katta bo'shliq: Qo'llash o'rniga, kesishish qo'pol, burmalar ko'payadi va hatto teshiklardagi xirillarning chekkasi.
2 Har xil alyuminiy qotishmalarining mexanik xususiyatlari (1060 ta toza alyuminiy va {{{6061-} qattiq alyuminiy) sezilarli darajada farq qiladi va bo'shliq maqsadli tarzda sozlanishi kerak. Bitingda qiyinchilik: alyuminiy chiplar mog'orga yopishish oson, shuning uchun diqqatni moylash va chipni o'chirish dizayni bilan to'lanishi kerak. Yumshoq alyuminiy qulash uchun moyil va qattiq alyuminiy yoriqlar bo'lishi mumkin.
3. Recommended value of aluminum plate punching gap Aluminum plate type Gap range (single side) Applicable scenarios Pure aluminum (such as 1060) 6%-10% T Low hardness, high ductility material Soft aluminum alloy (such as 3003) 7%-12% T Medium strength, general stamping Hard aluminum alloy (such as 5052-H32) 8%-15% T High hardness, low ductility material Super hard aluminum (such as 7075-T6) 10%-18% T High strength requirements such as aerospace Note: T is the material thickness, for example, 1mm thick aluminum plate, the recommended gap for pure aluminum is 0.06-0.1mm (single side). High-speed stamping (>200 times/minute) or thick plates (>3mm) 1% -3 ni 2% ga tenglashtirishi mumkin.
4. Chiqish materiallariga ta'sir ko'rsatadigan omillar: yupqa plastinka (t)<1mm): The gap is 6%-10% T to avoid excessive deformation of the material. Thick plate (T≥2mm): The gap needs to be increased to 10%-15% T to reduce the punching force. Mold conditions: When the mold steel (such as SKD11, DC53) has high hardness and is titanium-plated, the gap can be reduced by 1%-2%. The die edge is designed to be taper (such as 0.5°-1°), which is conducive to chip removal and extends the life of the mold. Lubrication and process: Using volatile stamping oil (such as fatty acid esters) can reduce aluminum chip adhesion and allow smaller gaps. In continuous mold production, the step accuracy must be controlled within ±0.02mm to avoid uneven gaps caused by cumulative errors.
5 Bo'shliq juda kichik: Yorqin guruh 60% dan yuqori va ikkilamchi qichishish belgilari burilishning ildizida paydo bo'ladi. Bo'shliq juda katta: sinish guruhi qo'pol, bar balandligi 0,1t dan katta va teshigi cheklangan. Tuzatish strategiyasi: Agar Burdard standartdan oshsa, kesishma chizig'i talablarga javob bermaguncha 5% t. Qattiq alyuminiyning chekkalari 2% {{13} {{R0. 1- t) optimallashtirilgan bo'lishi mumkin.
6. Ommaviy ishlab chiqarish bo'yicha iqtisodiy optimallashtirish bo'yicha takliflar: Lazerni kesish yoki protsessorni oldindan isbotlash uchun ishlatish, sudning narxini pasaytirishdan oldin mog'orni ochishdan oldin optimal tafovutni aniqlang.
Molde Ta'minot: Har 1 0 {{1 {{{{{{{{{{{}}}} 000}} 000} punktlari va tsementlangan karbid mog'orlari hayotiga 2 million martaga yetishi mumkin. Case qo'llanmasi: Birlashtirilgan elektron issiqlik botishi 1,5 mm qalinlikda 5052- 5052- 5052- 5052- 5052- 5052- ALUMINU plastinka ishlatdi. 12% t ({15}} ning boshlang'ich bo'shlig'i (0. Bir tomonida 18 mm. 15% t (0,225mm) ni sozlaganingizdan so'ng, burilish 0,05 mm ga tushirildi va mog'or hayoti 30 foizga uzaytirildi.
Xulosa: alyuminiy plastinkalarini teshish moddiy xususiyatlarga, jarayon sharoitlari va mog'or maqomiga asoslanib, dinamik jihatdan sozlanishi kerak. Tavsiya etilgan boshlang'ich qiymat oralig'i 6% {{1} {{1} {{1} {{1} ni tashkil etadi va u Mold Sudni tekshirish orqali optimallashtirildi. Aqlli tafovutlar asosiy tafovutni kesma, hayot va ishlab chiqarish narxini hisobga olish va muhrlash samaradorligini 20% dan ko'proq hisobga olishni hisobga olishi mumkin.
