AUTOMATIC WIRE CUTTER AND STRIPPER MACHINE
ABSTRACT
The study is centered on the design and fabrication of an Automatic Wire Cutter and Stripper Machine. In achieving this aim, the following specific objectives were laid out to design and fabricate an automatic wire cutting machine system that will: achieve low cost cutting and works fast in order reduces the cutting time, cut required length of wire in required number of pieces, and Efficient, User-friendly, Transportable and Reduce strenuous and repetitive task. In an automatic wire cutting machine a stepper motor driven knurled roller is positioned between two wire guide channels to drive a wire toward a cutting station. The length of wire to be cut is set in a length counter. Drive cycles, during which the wire is driven a predetermined distance, are counted in the length counter. Then, the stepping motor is disabled and cutting blade is energized. This system prevents operation of the cutting blade solenoid at less than an acceptable duty cycle with short lengths of wire. This automatic cutting machine is fully electric, microprocessor controlled bench machine for processing wire, round and flat cable. It features LCD display prompts for easy-to-follow set-up and operation, automatic wire loading and unloading and universal V-type blades. The relevance of the study surveys straightening and cutting process used in such machines. Although this review cannot be collectively exhaustive, it may be considered as a valuable guide for researchers who are interested to develop next generation of wire straightening cutting machines.
CHAPTER ONE
1.1 Introduction
The automation system solves labour problems which saves cost, increases accuracy and decreases human errors. After surveying various electrical and electronics industries we conclude that, nowadays the industries have introduced automation in their systems to some extent but for some basic processes which are time consuming like wire cutting, packaging etc. they use human resources. If we introduce automation to these basic processes then it will be fruitful regarding the company’s development and profit gain as it improves the system in many ways. One such industry found out in which they need a solution that is very efficient, fast and economical for cutting various lengths of wires which are required for producing capacitors. So we try to market cost effective wire cutting machine.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.
1.2 Background of Study
In an automatic wire cutting machine a stepper motor driven knurled roller is positioned between two wire guide channels to drive a wire toward a cutting station. The length of wire to be cut is set in a length counter. Drive cycles, during which the wire is driven a predetermined distance, are counted in the length counter. Then, the stepping motor is disabled and cutting blade is energized. This system prevents operation of the cutting blade solenoid at less than an acceptable duty cycle with short lengths of wire. This automatic cutting machine is fully electric, microprocessor controlled bench machine for processing wire, round and flat cable. It features LCD display prompts for easy-to-follow set-up and operation, automatic wire loading and unloading and universal V-type blades.
Company is using conventional method for wire cutting from conventional method the production rate is very low because they have to measure the length of wire for every piece before cutting which also take more time. Also sometimes wires unequal length as well as more man power is required. It should be noticed that waste minimization to zero can’t be achieved for many manufacturing processes at present, and only second principle in waste management hierarchy can be realized in many companies. It is not very difficult to recycle clean and homogeneous waste, but there can be serious problems with composite products made of different materials. In such a case, the waste separation (mostly multistage and high- priced) must be included in waste recovery process. One such composite product is waste cables. The cable scrap can be produced during manufacturing process (for example, rejected for insulating material defects) and due to the end of life of cables (for example, during repair of electric devices and buildings). The most valuable component of the cable that must be recycled is non- ferrous metals (copper, aluminum). The main cable waste recovery problem is how to remove plastic insulator from metal conductor. In the past cables were recycled by simply burning them. The copper remained solid and could be collected after burning.
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the Automatic Wire Cutter and Stripper Machine.
