Multifunctional and potent grinding wheel and belt head

• It is composed of remaining/appropriate transferring gadget, grinding & gouge head vertical rotating link flange, grinding & gouge head horizontal rotation device, grinding & gouge head side swing stopping device, grinding & gouge head, grinding motor, welding seam abrasive wheel and grinding system, root go effective abrasive belt grinding gadget (abrasive belt get in touch with wheel,tight and aspect swing preventing unit ,), Pneumatic constant force relocation system, computerized blade lifting device and du EPT elimination protect.
• Grinding & gouge head appropriate/still left horizontal shifting device consi EPT of motor, unique reducer, lateral modest slide manual rail. The function of the appropriate/still left horizontal transferring unit is to maintain the grinding centerline coincides with the unit middle line right after 90 degree rotating.
• Grinding & gouge head vertical rotating connection flange consi EPT of motor reduction unit. The purpose is to facilitate the abrasive belt to parallel with welding seam floor even though grinding the cladding welding seam.
• Grinding rotation device consists of rotation ring and supporter.  ±90 diploma can be modified as vessel interior, exterior longitudinal/ circumferential seam situations.
• Grinding & gouge head facet swing lock protecting against device consi EPT of lateral sliding gadget and connected tight lock gadget. The abrasive wheel can instantly adju EPT the course by means of sensor detection by subsequent welding seam.  The purpose is to avoid abrasive wheel blocked and hazardous happens whilst the grinding direction deflection takes place since the anti-floating roller without employing. Limited lock device is to maintain the abrasive grinding observe no deflection.
• The complete grinding & gouge head and grinding belt are utilizing very same beam and motor system, consistent force relocation and automated blade lifting system. The only difference is that the abrasive belt has independent wheel limited and facet swing protecting against gadget and covers.
• The abrasive belt can satisfy vessel internal and external grinding

PLC manage method
The grinding and gouge machine makes use of Siemens PLC (S7-three hundred) technique. To make it easy to operate the equipment, the transmitter cupboard handle largely relies upon on hand-held operation box management. Transmitter cabinet is located on the back of machine, every operate grinding & gouge head and add-ons are with different fa EPT interface. Pneumatic unit: air supply .4~.8mpa, it is with oil-h2o separator. Components are using SMC model. Grinding/gouge head coordinate control is driven by constant handbook variable frequency. The regular stress relocation system can take away the beam deflection during grinding and gouging, which means the abrasive wheel is always perpendicular to the axis of the vessel. Needed Linear velocity of vessel roller is  0.1-3m/minute during grinding or gouging
