a b s t r a c t In this study mainly concentrated on the automation method to produce new equipment. The Paper punching machine is one of the important equipment for to make holes for spiral binding process. The existing mechanism is a difficult one to form a hole based on the increasing of paper count, much more human effort is also needed. This study and design is to improve the equipment in the sense of automation, the automation help to improve spiral binding works with produce bulky spiral binding in the short period and also reduce the human effort. In this study replacing of pedal operated mechanism and introduces electric motor with drive mechanism, reduction gear box and cam mechanism. Ó 2019 Elsevier Ltd. All rights reserved.

1. Introduction
2. Components and its description
The eccentric cam mechanism is used for punching papers for spiral binding it can be used in all spiral binding shops [1]. To operating the punching head compulsory an electric motor is needed [2]. The electric motor selection is the major consideration because of power rating [3] and power consumption [4]. The electric motor rotates by means of applying power it drives the gear assembly it termed as reduction gear box [5]. The motor speed has modified through reduction gear box [6], gear box shaft has eccentric cam mechanism [7]. The eccentric cam operates the pull rod in up and down direction [8]. The pull rod further operates the punching head like as die set [9] Fig 1. When the motor is ON, the motor with speed reduction mechanism and cam will be rotates [10]. This rotation activate the pull rod constantly oscillates up and down [11]. Further the oscillation motion termed as ‘reciprocating motion’ [12] is transmitted to punching head and move the punching head die assembly it punches the papers [13] when the punching head moves in downward direction [14]. This automatic punching machine reduces human working effort [15] and fatigue also reduces the punching time than manually operated machine [16]. For that bulk number sets of paper can be punched in a very short time period [17], since this machine accomplish the requirements of the spiral binding shops [18].
The major parts used in the punching machine equipment are; [19]

2.1. Frame The frame is the rigid structure to hold the electric motor drive, reduction gearbox, pull rod and punching head mechanism [20]. The entire structure is made up of mild steel L-shape angle plate with simple constriction [21]. 2.2. Electric motor The electric motor is called as an electrical machine it is mainly used to converts electrical energy into mechanical energy (See Fig. 2.) [22]. Most of the electric motors are operated through the interface between the motor’s magnetic field [23] and electric current in a wire winding to generate force in the form of rotation of a shaft [24]. The shaft is connected to reduction gear box shaft [25]. 2.3. Punching head mechanism The punch head assembly is the model of rack and pinion structure [26]. The punching head has number of pins that is inserted or fixed [27] in the bottom surface of the punch head it is termed as ‘punch’ (See Fig. 3) [28]. The die set has multiple hole is mounted to the bottom of the punch in the frame [29]. The hole punching

[37] by means of two gears meshing condition as shown in Fig. 5 [38]. The two gears one has large in size with more number of teeth another one is small in size also less number of teeth [39]. The high speed incoming motion from the wheel work is transmitted to the set of rotating gears, [40] in which the motion or torque is changed [41]. 2.6. Eccentric cam mechanism Fig. 1. Schematic view of punching machine setup.
The camshaft uses lobes as termed as ‘cams’ the main suitable example of cam is the opening [42] and closing of valves in an automotive engine [43]. The cam rotates by means of reduction gear box shaft rotates [44], with the constant angular velocity [45], at that time the pull rod moves up and down as controlled by the cam surface (See Fig. 6) [46]. 2.6.1. Merits - Less time consumption [47]. - More number of papers can be punched in a single punch easily [48]. - Human fatigue is reduced [49]. - Less operational cost [50].

2.6.2. Application - It can be used in all spiral binding shops [51]. - It can also be used in paper punching industries. 3. Design dimensions of the structure Frame: 1000 * 600*1000 mm Electric motor: 1 Hp (3 phase) Punch: 40 pins (3 mm diameter) and 500*100*100 mm Die: 500*100*100 mm Pull rod: 600 mm length and 25 mm diameter

machines tender competence [30] and flexibility making competitive punching task with simply [31]. The punching capacities varied on the die pattern assembly [32]. The punching assembly works on the basis of pull rod movement [33]. 2.4. Pull rod The long round rod is called as pull rod as shown in Fig. 4 [34]. It is a simple rod one end is connected with punch head assembly another end has flat surface touches on the cam outer surface [35]. The eccentric cam is used to operate the pull rod in up and down movement [36]. 2.5. Reduction gear box The Reduction gear in the gearbox is used to convert the high speed of the output shaft rotation into low speed to the application
