  • To execute more than one tooling functions in a CNC lathe machine ‘gang tooling’ methods are being utilized; where multiple tools are mounted on the toolplate , mounted on the cross slide . Continuous working of the tools produces heat that may hamper the tool productivity and life, and also part quality.
  • coolant delivery systems are also equipped with the gang tooling on CNC lathe machines to cool off the working or machining zones. Another advantage of delivering a coolant around the working zones is chip removal and reducing any complications occurring from chip clogging.

  • the present invention provides a smart coolant delivery device to deliver coolant to a number of blocks in gang tooling of CNC machines.
  • the coolant delivery device is designed and manufactured in such a fashion that the coolant is delivered through internal channels build in the device, and hence avoids use of external pipes.
  • the smart coolant delivery device is in the shape of a plate made of a hard metal, where the plate has internal channels build for the coolant to flow through it.
  • the plate is referred to as‘smart plate’.
  • the smart coolant delivery device and the smart plate may be used interchangeably through the disclosure of the present invention.
  • the smart plate is installed with gang tooling of a CNC lathe machine.
  • the smart plate operates between a pump and a spindle of the CNC machine.
  • the pump pumps the coolant through a valve system that controls the flow of the coolant. Passing through the valve system, the coolant is delivered to the smart plate.
  • the smart plate has a plurality of coolant entry holes which are aligned on the rectangular plane surface along its length. Each entry hole further connects with a coolant transfer channel.
  • the coolant transfer channels are built into the smart plate through which the coolant flows and reaches the working zone of the spindle. This way the coolant flows from the pump to the working zone of the spindle, and cools of the zone. Further, this avoids implementing any external pipes to deliver the coolant to the working zone.

  • the coolant entry holes 102 receive coolant from the pump, and allow the coolant to pass through them. Further, the coolant entry holes 102 connect with the coolant transfer channels 104 which are build into the smart plate 100.
  • the coolant transfer channels 104 stretch from the rectangular plane surface with coolant entry holes 102 to the opposite rectangular plane surface of the smart plate 100. Further, the channels 104 end with the vertical coolant springs 106 through which the coolant moves out of the smart plate 100. Therefore, the coolant gets pumped from the pump and enters the smart plate 100 via the coolant entry holes 102, flows through the internal coolant transfer channels 104, and flows out of the smart plate 100 via the vertical coolant springs 106.

  • the pipeline 206 is fixed metal pipeline supplying coolant to the smart plate 100. Further, the coolant flows into the smart plate 100, through the coolant entry holes 102 and the connected coolant transfer channels 104 to eventually reach the block 208, mounted on the smart plate 100, via the vertical coolant springs 106.
  • the valve system 204 includes as many valves as there are blocks 208 mounted on the smart plate 100, where the valves are connected via the individual pipelines 206 with the smart plate 100 and eventually the block 208.
  • each block 208 has a flow control valve associated with it, controlling the flow of coolant through that particular block 208 via the associated pipeline 206 and the smart plate 100.
  • each block 208 mounted on the smart plate 100 is installed to spray coolant around the working zone of each tool in gang tooling of CNC machine. Further, flowing through the smart plate 100 and the block 208, the coolant is delivered to the working zone where a job 210 is being worked upon by a tool equipped onto a chuck 212 of a spindle of the CNC machine.
  • FIG. 3 illustrates a block diagram showing a coolant delivery system, including the smart plate, for gang tooling in CNC machines, in accordance with an embodiment of the present invention.

  • the smart plate has a number of blocks mounted on it, which eventually delivers the coolant to the working zones.
  • the smart plate ensures delivery of full quantum of the coolant to these blocks, since there is no leakage of coolant.
  • the smart plate enables the use of High Pressure Coolant (HPC) in Gang Tooling Machines to achieve very high machining parameters. This also helps in breaking of chips into small pieces.

Abstract

Selon des modes de réalisation, la présente invention concerne un dispositif intelligent de distribution d'agent de refroidissement, conçu et fabriqué sous la forme d'une plaque cuboïde et désigné sous le nom de plaque intelligente, pour distribuer un agent de refroidissement à une zone de travail dans un outillage en série d'une machine commandée par ordinateur (CNC). La plaque intelligente comporte une pluralité de canaux creux internes intégrés pour que l'agent de refroidissement s'écoule à travers ces derniers et atteigne la zone de travail en vue de la refroidir. L'agent de refroidissement sort d'un réservoir ; s'écoule dans la plaque intelligente, à travers les canaux internes ; et atteint les zones de travail. L'utilisation de la plaque intelligente comme dispositif de distribution d'agent de refroidissement évite le montage de tuyaux flexibles externes, généralement utilisés en vue de distribuer l'agent de refroidissement aux zones de travail. Par conséquent, la plaque intelligente évite une obstruction par copeaux, des dommages causés par les copeaux et la fuite de l'agent de refroidissement.
