RANCANG BANGUN AUTOMATIC PRESS TOOL UNTUK BLANKING CETAKAN KUE

Press tools can produce products in bulk with uniform quality and short time. The automation system applied to this press tool is a system to help channel metal plates to the press tool automatically called a feeder so that it can be called an automatic press tool. The technique that will be applied in this press tool is blanking technique. Blanking is a product of forming results that is used and is produced from one single cutting process with all forms of contour being cut in full, or the result of gradual cutting with the press tool. This research aims to design and prototype an automatic press tool to produce cake mold blanking using a pneumatic system that can work more effectively and efficiently. The research method was carried out in several stages, namely the design phase, the manufacturing stage, the assembly stage and the data analysis. The results obtained from this study produce automatic press tool blanking cake molds with a pneumatic system that is given a maximum compressive strength of 8 bars and a pressure force of 6280 N. This tool is able to produce aluminum blanking results on average of 17 to 18 pieces per minute without requiring a load high operator work.

Analisis Proses Manufaktur Alat Pengepres Geram Mesin Perkakas

Scattred industrial trash on mechanical company’s workshop will be dangerous for operator and employee. The aims of this research are to design, analyze and compare the function of automatic press tool of machining trash to a manual process. Method of this research are designing, manufacturing and testing. A tool was designed using inventor software, assembled and manufactured, then tested. As results, trash becomes neater, smaller, thus easier moved to the recycle process. It can operate with 2 ton maximum pressure and dimention 28,6 cm x 28,6 cm with 25 cm depth. Press tool produces an average pressing time with an automatic system 21.89 sec and reduction in space volume 7.670,7 mm3,whereas manual process, average pressing time 34,38 sec, space volume reduction 5.887,3 mm3.

SOCIALIZATION OF THE NEW METHOD FOR USE OF TOFU AUTOMATIC PRESS TOOL TO THE SME COMMUNITY

Based on observations, tofu home industry in several places in the city of Jakarta still uses conventional production methods. The printing and press process using conventional methods takes a long time the equipment used to print and press tofu is teak. According to home industry owners know to press 100 tofu in one container takes about 20 minutes. The process of producing tofu with a conventional system is less effective and efficient because it requires a long period of time. Based on these problems, the aim of this project is to socialize the new method of using the Automatic Tofu Press Tool so that it is useful in providing knowledge to the SME (Small Medium Enterprise) tofu community about more efficient and shorter press processes, and produces uniform production of both the texture and thickness of tofu produced.

Automatic press-fit assembly of small precision interference fitting parts: armature of electro-hydraulic servo valve

Purpose The purpose of this paper is to design an automatic press-fit instrument to realize precision assembly and connection quality assessment of a small interference fitting parts, armature. Design/methodology/approach In this paper, an automatic press-fit instrument was developed for the technical problems of reliable clamping and positioning of the armature, automatic measurement and adjustment of the attitude and evaluation of the connection quality. To compensate for the installation error of the equipment, corresponding calibration method was proposed for each module of the instrument. Assembly strategies of axial displacement and perpendicularity were also proposed to ensure the assembly accuracy. A theoretical model was built to calculate the resistant force generated by the non-contact regions and then combined with the thick-walled cylinder theory to predict the press-fit curve. Findings The calibration method and assembly strategy proposed in this paper enable the press-fit instrument to achieve good alignment and assembly accuracy. A reasonable range of press-fit curve obtained from theoretical model can achieve the connection quality assessment. Practical implications This instrument has been used in an armature assembly project. The practical results show that this instrument can assemble the armature components with complex structures automatically, accurately, in high-efficiency and in high quality. Originality/value This paper provides a technical method to improve the assembly quality of small precision interference fitting parts and provides certain methodological guidelines for precision peg-in-hole assembly.

DESIGNING PRESS MACHINE CANNED SOFTDRINK TO REDUCE VOLUME WASTE OF CANNED SOFTDRINK

Many processes in the industry originally done by humans, are now being replaced by machines that are driven automatically by simply giving commands / programs or just simple / semi-automatic buttons. This is intended for human energy efficiency and the effectiveness of completion time, due to the rapid progress of human resources (Human Resources) so that it is no longer possible to do the work manually with great energy.This Final Project aims to plan, manufacture, and test semi-automatic press machines for the purpose of automation of engine press. Methods in the design of this machine is the study of observation. From the design is done, generated a semi-automatic press machine, with the following specifications: Capacity of compressive strength with the power of pressing 150 kg. The electric motor used has a power of 0.5 PK and 1400 rpm rotation. Total cost for the manufacture of 1 unit of this machine is Rp 1.714.000, -.
