Method for manufacturing wheels

Abstract

To provide a manufacturing method of wheels which can easily and beautifully remove plating at the welding planned portion and which can manufacture wheels with rims plated at low price and efficiently. A method for manufacturing two-piece type wheels having a rim 2 and a disk, in which after providing a chromium plating to the rim 2 as a wheel component member, a welding planned portion RW with respect to the disk on the inner circumferential surface of the rim is ground by a grinding belt 29 , removing plating at the welding planned portion RW, thereafter the disk is fitted and fixed to the rim 2 so that the disk and the rim are welded and joined along the welding planned portion RW.

1 : A method for manufacturing wheels, comprising steps of: 
 providing a chromium plating treatment for wheel component members;    grinding a welding planned portions of each of the wheel component members by an abrasive cloth/paper to remove plating of the welding planned portion; and    welding to join each of the wheel component members along the relevant welding planned portions.    
   
   
       2 : A method for manufacturing two-piece type wheels having a rim and a disk, comprising steps of: 
 providing a chromium plating treatment for the rim as a wheel component member;    grinding a welding planned portion to the disk on an inner circumferential surface of the rim by an abrasive cloth/paper to remove plating of the welding planned portion;    fitting and fixing the disk to an inside of the rim; and    welding to join the disk and the rim along the relevant welding planned portions.    
   
   
       3 : The method for manufacturing wheels according to  claim 2  wherein the welding planned portion is ground by pressing and bringing the abrasive cloth/paper into contact with the inner circumferential surface on a bottom of the rim with the rim set in a state of setting a center axis thereof made substantially parallel to support rollers onto two of the parallel support rollers with center axes thereof made substantially horizontal when the inner circumferential surface of the rim is being ground.  
   
   
       4 : The method for manufacturing wheels according to  claim 2 , wherein one end of a grinding belt used as the abrasive cloth/paper is stretched over a pulley which can be inserted in the wheel and is rotatable around a center axis thereof substantially parallel to a center axis of the wheel, and the other end is stretched over a pulley rotatable around a vertical center axis thereof arranged outside of the wheel.  
   
   
       5 : A method for manufacturing three-piece type wheels having an inner rim, an outer rim, and a disk, comprising steps of: 
 providing a chromium plating treatment to the outer rim as a wheel component member;    grinding a welding planned portion on an outer circumferential surface of a curved portion linked from a superimposed parts of rims to a cylindrical body part in the outer rim by an abrasive cloth/paper to remove plating of the welding planned portion;    assembling both of the rims by superimposing the superimposed parts while superimposing an outer circumferential parts of the disk to the superimposed parts;    fixing the disk to the superimposed parts with bolts; and    welding to join the welding planned portions of both of the rims from an outside.    
   
   
       6 : The method for manufacturing wheels according to  claim 5 , wherein a flap wheel with an abrasive cloth arranged radially is used as the abrasive cloth/paper, and the flap wheel is pressed and brought into contact with a center part of the welding planned portion in a substantially vertical state so as to grind the welding planed portion.  
   
   
       7 : The method for manufacturing wheels according to  claim 3 , wherein one end of a grinding belt used as the abrasive cloth/paper is stretched over a pulley which can be inserted in the wheel and is rotatable around a center axis thereof substantially parallel to a center axis of the wheel, and the other end is stretched over a pulley rotatable around a vertical center axis thereof arranged outside of the wheel.
