Abstract

Rear Axle Bumper Bracket is a non-frame part of the car that functions to connect the bumper itself to the rear axle and to withstand collisions and also reduce collisions. Rear Axle Bumper Brackets are commonly used for vehicle components. This writing aims to determine the process of making the Rear Axle RH Bumper Bracket and the total force in the blanking (cutting) process and also in the bending (bending) process of the RH Rear Axle Bumper Bracket Lower Part. Bumper Rear Axle Bracket RH is made by going through a material formation process by cutting blanking and bending, followed by a welding process using spot welding to the painting stage using a powder coating method of dipping. Based on the results of calculations using SPH 440 OD material for the main material for making Bracket Bumper Rear Axle RH Lower Part, it was found that the amount of tonnage that occurred in the blanking process (cutting) was 84.09 Tons with an added reserve force of 8.41 Tons with a value of 84.09 Tons. safety factor of 1.3 which has been standardized on the use of static loads so as to produce the capacity of the press machine needed for the blanking process (cutting) which is 120.25 tons with the actual press machine used of 110 tons. For the bending process, it can be done with a total bending force of 27.19 tons with the added pad force in the bending process of 6.8 tons so that the total force on the Press machine needed for the bending process is 34 tons with the actual press machine. used is 110 tons.

Abstract

In this century, the industrial sector is a very important sector to support the national economy. The industrial sector contributed very high so that it succeeded in bringing Indonesia to the 85th rank out of 131 countries in the world's manufacturing industry, the industrial sector was growing very rapidly accompanied by increasing positive growth. Bracket assy is a component or frame structure on a bulldozer that uses SS400 and ST37 type steel metal material, which means that the component is very strong and does not break easily when exposed to heavy loads. Bracket assy is a product that has gone through various fabrication processes. The function of the bracket assy is as a handle for the hydraulic system pipe and also the pedestal of the body or engine cover, the bracket assy is located above the front of the car chassis which is positioned facing up. The process of making the bracket assy, namely, the selection of materials used in the process of making the Bracket Assy, namely Steel SS400 and ST 37, Gas Cutting Machines, Bending Machines, and Welding Machines. In the cutting process of the Gas Cutting Machine, the workpiece is cut. Next is the Bending Machine process where the workpiece is bent. Furthermore, the welding process of the workpiece is welded in 2 stages, namely the first tack welding and full welding / Fillet Weld, then Quality Control is carried out to check whether the product is ready to be distributed, the product is qualified into two types, namely GOOD for products that have passed Quality control and NOT GOOD for products that do not pass Quality Control.

Abstract

The use of automation systems is needed in sorting, one of which is the sorting of objects based on the size of the object being sorted. Especially in the sorting process, there are still many industries that use conveyors that only function for one product with the same weight characteristics. Therefore, to sort the same goods with different weights, a separate conveyor is needed so that many conveyors are used. The development of a sorting machine is an important aspect in the modern automation and manufacturing industry. This research aims to design and analyze the static loading of the sorting machine frame using SOLIDWORKS software. The design method used includes detailed 3D modeling of the machine frame by considering the strength, stability and reliability of the structure. The simulation results using SOLIDWORKS software show the stress (von Mises) with a maximum value of 82.26 MPa, while the theoretical calculation result is 84 MPa. Displacement with a maximum value of 4.063 mm, while the theoretical calculation result is 1.60 mm. The safety factor is 2.38, while the theoretical calculation result is 2.43. The difference between manual calculation and simulation is 0.02% for von Mises stress, 1.5% for displacement, and 0.02% for safety factor.
