Abstract

This metal forming technology dissemination activity involved three partners from micro, small and medium enterprises (MSMEs) engaged in the metal forming industry in the village of Karangsentosa, Karangbahagia District, Bekasi Regency. The main problem faced by partners is the difficulty in designing dies for the combination of piercing and blanking processes. This difficulty resulted in the piercing and blanking processes being carried out separately, resulting in less efficient production performance and higher production costs, thus requiring a reverse engineering process for some of its products. The method used in this dissemination process was an experimental method by doing reverse engineering on one of the products produced, namely the ducting corner. The purpose of this metal forming technology dissemination is to assist partners in increasing the efficiency of the production process by combining piercing and blanking processes into one process. In this metal forming technology dissemination activity, efficiency has been carried out from nine stages of the production process to five production processes. The combination of blanking and piercing processes using 1.2 mm SPCC-SD material for the production of ducting corners requires a minimum power press machine capacity of 18.3 tons. Further dissemination will be carried out by combining the piercing, blanking and bending processes by applying the progressives dies design.

Abstract

The development of science and technology has an important role in the success of development in the industrial sector. In the industrial world, machining processes are very important. A scrap machine is a machine tool that is used to change the surface of a workpiece into a flat surface with levels, corners and grooves.This research aims to find out the causes of damage to the automatic movement of the table, to determine the strength of the material using impact testing and calculating torsional moments, and to be able to repair damage using the welding method using brass. Damage that occurs to the automatic movement of the table is caused by the final limit of the moving table being exceeded. On a sledding table there is no final limit for the moving table, when the final limit for the moving table occurs, the automatic moving machine continues to work and exceeds the material strength limit of 14,133 joules and 1422 N.m, causing the nut to be damaged. Repairing the sliding table nut is done by welding. This welding is carried out using brass, brass is used because it has high wear resistance. Keywords: Scrap Machine, torsional moment, impact test, cause of damage.

Abstract

Dalam proses produksi salah satu kegiatan yang umum adalah material handling yaitu penanganan atau pemindahan bahan baku dari satu proses ke proses yang lainya. Proses pemindahan material atau material handling dibutuhkan pesawat angkat dan angkut. Salah satu pesawat angkut yang digunakan adalah mesin Screw conveyor. Mesin digunakan untuk memindahkan material berupa clay yaitu berupa butiran butiran tanah yang sudah dikondisikan dengan ukuran tertentu yaitu berukuran 5mm sampai 30mm. Bagian pada mesin ini yang sering mengalami kerusakan adalah bagian bearing, hal ini dikarenakan semua beban untuk mendorong material bertumpu langsung dengan bearing. Untuk menentukan kekuatan bearing yang dipakai maka harus dibuat dulu rancangan dasar dari mesin tersebut, yaitu kapasitas mesin, jenis material, gaya yang bekerja pada bagian bearing. Disini telah didapatkan data kapasitas mesin screw conveyor adalah 11.000 kg/jam, kekuatan bearing secara perhitungan yaitu Bearing QJ304: 15.637 jam, Bearing NU304: 38.683 jam, dan Bearing 22316: 50.937 jam. Untuk mendapatkan kondisi aktual bagian bearing yaitu pengukuran vibrasi. Dalam hal vibrasi alat ukur akan menunjukan besarnya velocity. Velocity adalah jumlah waktu yang dibutuhkan ketika terjadinya displacement atau kecepatan getaran suatu benda. Secara garis besar Velocity mewakili kondisi kerusakan bearing yang diaktualisaikan dengan niali 0-11 yaitu merujuk pada Standard ISO 10816-3. Sehingga akan didapatkan hasil perbandingan dari perhitungan perencanaan mesin dan aktualnya.
