Abstract

Today the need for housing (home) is increasing. Touch of beauty and support in terms of security are widely used in the construction of the house, one of the trellis. One of the production processes in processing iron trellis is the process of forming spiral iron trellis models of a certain size, in the process special machines are needed that can alleviate, simplify, and accelerate human work. This process is also called cold work because without the heat treatment process. The specifications of the trellis iron torsion machine are 1500x500x800 mm. This machine has several driving units, namely: Motor as a driver, and reducer to reduce the rotation of the shaft on the swivel chuck, and use belt transmission and chains. From the calculation and design of the engine, the motor power of ½ Hp is obtained, the production capacity is 10x10x1000 mm, the shaft diameter is 25.4 mm. The production time of this machine is 7 times / workpiece or ± 2 minutes / Pcs or 29 to 30 Pcs / hour. This trellis iron torsion machine works well and gets a better and stronger spiral model iron box. The components contained in this machine include: Electric motors, pulleys, belts, frames, sprocket, chains, chucks, bearings and speed reducers.

Abstract

The design of the cassava slicer machine has a capacity of 38 kg / hour, this machine is designed to design a cassava slicing machine that has high usability, achieving the required motor power so that the desired engine capacity can be achieved, able to determine the exact method of slicing cassava . The working principle of Cassava Slicing Machine is to work when the electric motor is turned on, then the motor will rotate then the motor rotation is transmitted to the pulley, moving the slicing knife by 0.03653 N / mm2. After the shaft rotates, the disc where the blade will rotate and the cassava is ready for slices and the results of the cassava slices will come out through the output funnel. Cassava slicing machine using 1/2 HP motor with 1400 rpm rotation as its driver, and Framework with L St.37 profile material, type A belt, bearing with UCP205-16 type
