CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[001] The present application claims priority from Indian provisional application no. 201821048280 filed on 20th December 2018.
TECHNICAL FIELD
[002] The present subject matter described herein, in general, relates to a system for cutting a pipe.
BACKGROUND
[003] Generally, in the process of cutting of pipes, there is a process which requires continuous adjustment and realignment according to the thickness of the pipes. This is also because of bending of the pipes/bars while cutting. Due to the use of conventional machines for cutting the pipe, the total time to complete pipe cutting process increases upto 46 minutes, whereas the standard time for cutting one pipe is 4 minutes. Hence, it requires 11 times more time as compared to the standard time required for cutting one pipe.
[004] Such conventional machines have certain limitations such as complexity of tools, higher cost, higher maintenance, etc., which further results in decreased productivity and increase consumption of time. Further, due to the use of conventional machines, the cutting process becomes unsafe and tedious/tiresome for the operatives. Due to the fatigue and excess time, the productivity gets affected.

[0019] Referring to figure 1, that represents a three-dimensional view of a system 100 for cutting a pipe, in accordance with an embodiment of the present subject matter. The system 100 comprises at least two side blocks 104, a middle block 106, a top opening 108, a set of rollers 110, wheels 112, a tray 114, a base frame 116, a channel 118, at least one track 120, a set of slots 202 (shown in figure 2), a bottom opening 402 (shown in figure 4) and angles 502 (shown in figure 5).
[0020] The at least two side blocks 104 and the middle block 106 are configured to hold a pipe 102 horizontally in a longitudinal manner. The pipe 102 may be a pillar pipe 102 or any other pipe and may be made of a steel, an iron, an aluminum, etc. Each of the at least two side blocks 104 and the middle block 106 comprises of a box section with a top opening 108. The top opening 108 of each of the at least two side blocks 104 and the middle block 106 is a U-shaped opening or a rectangular shaped opening. The top opening 108 of each of the at least two side blocks 104 and the middle block 106 comprises the set of slots 202.
[0021] Further, the plurality of sets of slots 202 are configured for rotatably mounting of the set of rollers 110. The pipe 102 is placed on the set of rollers 110. The set of rollers 110 are idler rollers configured to provide rotational motion of the pipe 102. Further, a cutting operation is performed perpendicular to an axis of the pipe 102 on its circumference. Furthermore, the cutting operation is performed on a portion of the pipe 102 that is placed above the middle block 106 in order to prevent falling down of separated pieces of the pipe 102 after cutting.
[0022] In one embodiment, the plurality of set of slots 202 are configured to mount the set of rollers 110 at different slot positions to accommodate the pipe 102 of different diameters. The set of slots 202 may be separated with a predefined distance. The set of rollers 110 may be shifted from one set of slots to another set of slots in order to accommodate the pipe 202 of different diameter.
[0023] The system 100 comprises the base frame 116. The base frame 116 may have a rectangular shape. The base frame 116 further comprises the channel 118 and the track 120. The at least two side blocks 104 are rigidly mounted at two extreme corners of the base frame 116 and the middle block 106 is movably mounted on the base frame 116. The wheels 112 are connected at a bottom of the middle block 106 for facilitating lateral to and fro motion of the middle block 106 on the track 120 of the base frame 116. Further, the angles 502 are provided at the bottom of the middle block 106.
[0024] The bottom of the middle block 106 is provided with a bottom opening 402. Further, the angles 502 are provided at the bottom of the middle block 106 configured for mounting of a tray 114. The tray 114 is slidably mounted in said angles 502 by inserting through the slots created by angles 502 to cover the bottom opening 402. The tray 114 is configured to collect scrap coming from the top opening 108 of the middle block 106 while performing cutting operation.
[0025] The system 100 for cutting the pipe 102 is advantageous because it minimizes the cutting time and maintain standard cutting time per pipe 102 as the system 100 provides the rotation of the pipe 102 section on the plurality of idlers rollers 110. The system 100 ensures the safety of the operators as the middle block 106 supports and prevents falling down of separated pieces of the pipe 102 after cutting. It further reduces fatigue of the operators/workers during handling of the pipe 102. Further, the system 100 increases the productivity.
[0026] Due to the use of the system 100 for cutting the pipe 102, total cutting time reduces from 46min. to 25 min. and cutting time per pipe 102 is maintained to 4min. (standard cutting time). Further, total number of pipes cutting per day is increased from 4 pipes to 6 pipes.
[0027] The present subject matter discloses a system 100 for cutting a pipe 102. The system 100 comprising: at least two side blocks 104 comprising a top opening 108; a middle block 106 comprising the top opening 108, wherein the at least two side blocks 104 and the middle block 106 are configured to hold a pipe 102 horizontally in a longitudinal manner; and a set of rollers 110 configured to be rotatably mounted on the top opening 108 of each of the at least two side blocks 104 and the middle block 106 to facilitate rotational motion to the pipe 102 to facilitate cutting.
[0028] Further, said middle block 106 is configured to adjust itself to support and place it below the pipe section to be cut to facilitate support to both the ends of the separated pieces after cutting. The top opening 108 of each of the at least two side blocks 104 and the middle block 106 is a U-shaped opening or a rectangular shaped opening. The system 100 is configured with as claimed in a base frame 116 having a channel 118 and a track 120 for receiving the at least two side blocks 104 and the slidable middle block 106. The system 100 is configured to perform cutting operation perpendicular to an axis of the pipe 102, on a portion of the pipe 102 placed above the middle block 106.
[0029] Furthermore, the at least two side blocks 104 are rigidly mounted at two extreme corners of the base frame 116 of rectangular shape and the middle block 106 is slidably mounted on the base frame 116 through wheels 112 connected at a bottom of the middle block 106 for facilitating to and fro motion of the middle block 106 on the track 120 provided along the length of the base frame 116. The middle block 106 comprises a bottom opening 402 configured to transfer the metal burr to a tray 120 slidably mounted in the slot of angles 502 provided at the bottom of the middle block 106.
[0030] Further, a tray 120 is configured to cover the bottom opening 402 and collect burr/scrap coming from the top opening 108 of the middle block 106 during the cutting operation. The top opening 108 of each of the at least two side blocks 104 and the middle block 106 is configured with plurality of said set of slots 202. The set of rollers 110 are configured to be rotatably mounted in any of the plurality of said set of slots 202 to accommodate the pipe 102 of various diameters.
