Roll-drawing machine

Abstract

A roll-drawing machine adapted for an elongated material is provided. The roll-drawing machine includes at least one rolling module and a power source. The rolling module includes a mold frame, a pair of seats, and a pair of rollers. The seats are movably disposed in the mold frame. The rollers are freely pivoted in the seats respectively and move together with the seats. An end of the elongated material is connected to the power source to be drawn thereby, such that the elongated material passes between the rollers of the rolling module to rotate the rollers and be pressed by the rollers.

What is claimed is: 
     
         1 . A roll-drawing machine adapted for an elongated material to change a size and a surface profile of the elongated material, the roll-drawing machine comprising:
 at least a rolling module, comprising:
 a mold frame; 
 a pair of seats movably disposed in the mold frame; 
 a pair of rollers freely pivoted in the pair of seats to move together with the pair of seats; and 
   a power source, wherein an end of the elongated material is connected to the power source and drawn by the power source to pass between the pair of rollers of the at least one rolling module to drive the pair of rollers to rotate and be rolled and pressed by the pair of rollers.   
     
     
         2 . The roll-drawing machine according to  claim 1 , wherein the rolling module further comprises:
 an adjustment component disposed through the mold frame and movably abutting between the pair of seats to adjust a distance between the pair of seats.   
     
     
         3 . The roll-drawing machine according to  claim 2 , wherein the adjustment component comprises:
 an adjustment block disposed through the mold frame to be movable along a first axis and having a pair of wedge surfaces to respectively abut the pair of seats; and   a locking part disposed in the mold frame and abutting the adjustment block, wherein the locking part rotates about the first axis and moves, and drives the adjustment block to move along the first axis and drives the pair of seats to move close to or away from each other along a second axis.   
     
     
         4 . The roll-drawing machine according to  claim 3 , wherein the pair of rollers is disposed along the second axis to respectively rotate about the first axis, and the elongated material passes between the pair of rollers along a third axis, and the first axis, the second axis, and the third axis are orthogonal to one another. 
     
     
         5 . The roll-drawing machine according to  claim 1 , wherein the rolling module further comprises a plurality of bearings respectively disposed between the pair of rollers and the pair of seats. 
     
     
         6 . The roll-drawing machine according to  claim 1 , further comprising a plurality of elastic members respectively abutting between the pair of seats and the mold frame, wherein a deformation direction of each of the elastic members is consistent with a movement direction of each of the pair of seats. 
     
     
         7 . The roll-drawing machine according to  claim 1 , comprising a base and a plurality of the rolling modules, wherein the rolling modules are stacked on one another and disposed upright in series on the base, and the elongated material is drawn by the power source to pass between the pair of rollers of each of the rolling modules. 
     
     
         8 . The roll-drawing machine according to  claim 7 , wherein on a plurality of normal planes formed by a drawing axis of the elongated material, the rollers of the rolling modules respectively roll and press the elongated material in different axial directions.
