Fixtrut merupakan sebuah pipa schedule dengan material mild steel yang diberi pengerjaan cutting, punching, stamping, serta pelapisan logam dengan metode hot dip galvanized. Fixtrut berfungsi untuk menstabilkan antena komunikasi yang telah terpasang pada tower telekomunikasi. Pada penulisan ilmiah ini membahas proses produksi fixtrut dan pelapisan logam hot dip galvanized di PT. RJU. Pada proses produksi fixtrut ini menggunakan metode jenis pabrikasi logam, artinya proses yang dilakukan dengan merubah bentuk di benda kerja. Perubahan bentuk ini dapat dilakukan dengan cara memberikan gaya luar sehingga terjadi deformasi plastis. Metode proses produksi fixtrut di PT.RJU melalui 6 tahapan, yaitu pemilihan material, cutting dengan mesin gerinda, stamping, punching, pembuatan ventilasi, serta pelapisan hot dip galvanized. Pada proses hot dip galvanized ada 5 tahapan yang harus dilalui, yaitu pickling merupakan pencelupan dengan asam klorida, lalu rinsing merupakan pembilasan dengan air bersih, fluxing merupakan pencelupan dengan larutan flux, molten zinc bath merupakan proses galvanisasi dengan temperatur 440 ºC – 460 ºC, dan terakhir quenching merupakan proses pendinginan dengan larutan chromat.
Meat is one of the agricultural commodities needed to meet protein needs, because meat contains high quality protein, which is able to contribute complete essential amino acids. The purpose of this paper is to design, analyze the static strength of the frame based on theoretical calculations and simulations on solidwork 2018 software. This machine consists of a frame, reservoir, grinding shaft, transmission, and electric motor. The results of the design obtained a Meat Grinding Machine with Length: 610 mm, Width: 500 mm and Height: 750 mm. The material used is 2024-O Alloy with a modulus of elasticity of 72,400 N/mm2. The load force obtained is 576.32 N. And the value from the analysis is the displacement value of 0.174 mm and for theoretical calculations, the displacement value is 0.176 mm. So, the value of the percentage error is 1.176%. For the von Mises value of 68,970 MPa, and for calculations based on the theory, the von Mises value is 52,499 MPa. So, the value of the error percentage is 0.238%. And for the value of the safety factor obtained a value of 1,087, and for calculations based on the theory, the value of the safety factor is 1.428. So, the value of the error percentage is 0.313%.
Fundamental, detailed and in-depth understanding of technology is carried out through the use of concrete pumps used to move fluid from one place to a higher place, high pressure and circulation. One of the important components of the pumping system in the industry is the Gearbox Bearing Housing which functions as a bearing housing so that the bearing can move and continue the shaft work system on the pump. The material used to make the Gearbox Bearing Housing is based on FCD 400. The manufacturing process for the Gearbox Bearing Housing is a lathe where in this process the workpiece is fed by rotating the workpiece and then touching it to a chisel which is moved in translation parallel to the axis of rotation. of the workpiece. The outer diameter is 700 mm, while the inner diameter is 340 mm and D2 is 440 mm. Drilling Machine Process, the machining process is the process of expanding or enlarging a hole that can be done with a drill bar. For the size of the holes, namely the diameter of 22 mm as many as 16 holes, the diameter of 20 mm as many as 16 holes and for the diameter of 12 mm there are 4 holes. Grinding Machine Process is a finishing process that is used to remove parts of the workpiece that are uneven. In the manufacture of Gearbox Bearing Housing, checks are carried out on the workpiece to determine whether or not an item is produced. If the workpiece is said to be feasible, it will be packaged to be marketed, if not, the workpiece will be destroyed.
Garbage is a problem of concern worldwide. Public awareness in disposing of waste that is not in its place causes various kinds of problems, one of the problems that occurs is in rivers or artificial canals. This is what makes many people create tools to make it easier to control improper waste disposal. One of the tools that was created was a garbage collector, in making the design of a garbage collection machine using solidworks software, Galvanized Steel material was used with a rod size of 30 x 30 x 2.6 (mm) as the frame. With a frame size of 1320 mm in length, 790 mm in width and 1133 mm in height. The results of the simulation using solidworks software on the frame of the garbage collection machine are to get the von misses stress value with a maximum stress value (MPa) and a minimum stress value of (MPa), for the displacement value with a maximum stress value of 0.61 mm and for a minimum stress value of 0.00 mm, the safety factor gets a value of 3.55 ul. In the comparison of solidworks and theoretical software values, the value for von misses stress is 0.04%, for displacement is 0.24%, and for safety factor is 0.20%.
In this modern era, the industrial world continues to experience rapid development, especially in the manufacturing process, particularly in machining processes. The production process is a way, method, and technique for creating, processing, or adding value to a product or service using available resources such as labor, machinery, materials, and funds. The purpose of this writing is to understand the production process for making Horz Cam Masema AW6035- SR using VCN 150 material. It also involves simulating static tests using Solidworks software to analyze von misses, displacement, and fatigue values. This writing is based on field studies and literature reviews conducted by the author. The simulation results conducted with a torque loading of 16.67 Nm obtained a maximum von misses value of 228,788,416 N/m2 and a displacement value of 0.222 mm. Therefore, the obtained fatigue values include the highest damage percentage of 0.488 and a minimum total life of 204,845 times.
