What Is Stamping?
Stamping adalah proses pembentukan benda kerja (stamping part) dengan menerapkan gaya eksternal pada pelat, strip, pipa dan profil dengan menekan dan mati untuk menghasilkan deformasi atau pemisahan plastis. Stamping dan penempaan termasuk dalam pemrosesan pembentukan (atau pemesinan tekanan). Bahan stamping terutama pelat baja canai panas dan canai dingin dan strip baja.
Stamping is the production technology of product parts with a certain shape, size and performance by using the power of conventional or special stamping equipment to make the sheet metal directly deformed and deformed in the mold. Sheet metal, mold and equipment are the three elements of stamping process.
Hot Stamping And Cold Stamping
According to the stamping temperature, it can be divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity, while the latter is carried out at room temperature, which is a common stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure machining), and also belongs to material forming engineering technology.
The Stamping Die For Sheet Metal Forming
Die yang digunakan untuk stamping disebut stamping die, atau die. Punching die adalah alat khusus untuk memproses bahan batch (logam atau non-logam) ke dalam bagian stamping yang diperlukan. Punching die sangat penting dalam stamping. Tanpa meninju mati yang memenuhi persyaratan, stamping massal sulit dilakukan. Tanpa die lanjutan, proses stamping lanjutan tidak dapat direalisasikan. Proses stamping dan die, peralatan stamping dan bahan stamping merupakan tiga elemen dari proses stamping, hanya jika mereka menggabungkan satu sama lain untuk mendapatkan bagian stamping.
The Steps Of Stamping Process
Stamping is mainly classified according to technology, which can be divided into two categories: separation process and forming process.
The separation process, also known as blanking, aims at separating the stamping parts along the contour line and ensuring the quality requirements of the separation section.
The purpose of forming process is to make the sheet metal plastic deformation without breaking the blank, and make the workpiece with the required shape and size. In actual production, many kinds of processes are usually applied to a workpiece. Blanking, bending, shearing, stretching, bulging, spinning and straightening are the main stamping processes.
Proses pemisahan
(kosong)
Ini adalah proses stamping dasar menggunakan bahan pemisahan mati. Itu bisa langsung dibuat menjadi bagian datar atau untuk proses stamping lainnya seperti membungkuk, menggambar, membentuk dan sebagainya. Itu juga dapat dipotong dan dipangkas pada bagian stamping yang terbentuk. Blanking banyak digunakan di otomotif, peralatan listrik rumah tangga, elektronik, instrumentasi, mesin, kereta api, komunikasi, industri kimia, industri ringan, tekstil dan kedirgantaraan dan sektor industri lainnya. Proses meninju menyumbang sekitar 50% hingga 60% dari keseluruhan proses stamping.
Proses pembentukan
Bending: metode pembentukan plastik untuk menekuk pelat logam, fitting dan profil ke dalam sudut, kelengkungan, dan bentuk tertentu. Bending adalah salah satu proses utama yang banyak digunakan dalam produksi bagian stamping. Pembengkokan material logam pada dasarnya merupakan proses deformasi elastik-plastis. Setelah dibongkar, benda kerja akan menghasilkan pemulihan elastis dan deformasi, yang disebut springback. Springback mempengaruhi akurasi benda kerja, yang merupakan teknologi utama yang harus diperhatikan dalam proses bending.
Deep drawing Of Stamping Process
Deep drawing also known as drawing or calendering, is a stamping process using moulds to make flat billets into blanks after punching. The deep drawing process can be used to make cylindrical, stepped, tapered, spherical, box shaped and other irregular shaped thin-walled parts. If combined with other stamping processes, parts with extremely complex shapes can also be manufactured.
In the stamping production, there are many kinds of drawing parts. Because of its different geometric features, the position of the deformation zone, the nature of the deformation, the distribution of the deformation, and the stress state and distribution of each part of the blank are quite, even the essential difference.
Therefore, the determination of process parameters, procedure number and sequence, and the design principles and methods of mold design are different. According to the characteristics of deformation mechanics, all kinds of deep drawing parts can be divided into four types: straight wall rotary body (cylindrical part), straight wall non revolving body (box body), surface slewing body (surface shape part) and surface non revolving body.
Gaya tarik diterapkan pada bahan lembaran oleh cetakan gambar untuk menghasilkan tegangan tarik dan regangan tarik yang tidak merata, dan permukaan ikatan pelat dan cetakan gambar secara bertahap mengembang sampai benar-benar sesuai dengan model gambar. Objek utama gambar adalah kulit hiperbolik dengan plastik tertentu, luas permukaan besar, kelengkungan halus dan halus, dan kualitas tinggi (bentuk akurat, streamline halus, dan kualitas stabil). Karena peralatan dan peralatan proses relatif sederhana, biaya menggambarnya rendah dan fleksibel, tetapi pemanfaatan dan produktivitas materialnya rendah.
Process Used For Deep Drwaing
Pemintalan is a metal rotary processing technology. In the process of processing, the billets are actively rotated with the spinning die or spinning head around the billet and the spinning die actively, and the spinning head is fed by the core die and the blank. The blank revolving parts are obtained by the continuous partial deformation of the blank.
Membentuk is the two trimming of the shape of the product using the shape of the tool. It is mainly reflected in the pressure plane, the bullet and so on. In view of the elasticity of some materials, it is impossible to guarantee the quality of the forming.
Menonjol is the processing method of obtaining parts by using die to make sheet metal thinning and increasing surface area. It is commonly used in the form of undulation, bulging of cylindrical (or tubular) blanks and stretching of flat blanks. Bulging can be realized by different methods, such as bulging, rigid bulging and hydraulic bulging.
bergelang is a plastic processing method to bend the material in the narrow strip area of the edge of the blank or the edge of the blank on the curve or straight line. The flanging is mainly used to strengthen the edge of the parts, remove the cutting edges and make the parts assembled and connected with other parts on the parts or the three-dimensional parts with complex specific shape and reasonable space, and improve the stiffness of the parts. In large sheet metal forming, it can also be used as a means to control breakage or crease. So it is widely used in automobile, aviation, aerospace, electronics and household appliances.
Leher is a stamping method that reduces the diameter of the flanged hollow part or the open end diameter of the tube blank. The change of the end diameter of the workpiece before and after the necking should not be too large, otherwise the end material will wrinkle because of the severe compression deformation. Therefore, it is often necessary to shrink the necks from smaller diameters with larger diameters.
