Problems solved by technology
[0003] In the current drawing reel, the drawn wire and the reel have circumferential and axial relative sliding. The more serious circumferential relative sliding will cause defects such as scratches and streaks on the surface of the wire, especially for those with relatively low drawing hardness. Copper and aluminum and other non-ferrous metal wires, especially the surface defects, will also have a negative impact on the force of the mechanical device

Embodiment Construction
[0016] The inventor found through research that the reason for the relative sliding of the drawing reel in the prior art is analyzed as follows: the drawing reel rotates at a certain speed, and the wire first accumulates on the cylindrical surface of the drawing reel, which is called the accumulation line. The contact friction resistance between the wire and the drawing reel provides the required drawing force for the wire, and also keeps the incoming wire at the position when it enters the drawing reel, as the wire is continuously wound onto the drawing reel , and finally wound and arranged on the arc surface, the diameter of each circle gradually increases, and the speed of the wire increases. At this time, there is a gap between the speed of the wire entering and exiting. At its contact point, a component force along the radial direction of the drawing reel and along the vertical direction of the radius is generated. When the component force along the vertical direction of t...

Abstract
The invention discloses a drawing reel. The drawing reel comprises a reel, and a plurality of driving pulleys arranged on the side wall of the reel; the axial direction of the driving pulleys and the radial direction of the reel are arranged in parallel; the initial position wherein a drawn wire material is reeled by the reel is provided with a first driving pulley, and the rest driving pulleys are uniformly distributed along the circumference of the reel; the height of the first driving pulley is taken as a standard, the installation height of the rest driving pulleys is increased successively along a rotating direction of the reel, the installation height of each driving pulley is increased by d / (N-1) compared with the installation height of a former driving pulley, wherein d is used for representing the diameter of the drawn wire material, and N is used for representing the number of the driving pulleys. The driving pulleys are used for realizing upward shifting of accumulated wire, no wire material circumference relative sliding is caused in drawing processes, the drawing reel is relatively suitable for drawing of nonferrous wire materials with low hardness, wire material surface defects can be reduced obviously, and drawing process is more stable.
Description
technical field [0001] The invention relates to the technical field of metal wire processing, in particular to a drawing reel. Background technique [0002] The drawing machine is the main equipment for drawing various metal wires. The drawing reel is the main part of the drawing machine. Please refer to figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a drawing reel in the prior art, figure 2 It is a partially enlarged view of the drawing reel, the working surface of the drawing reel is composed of a cylinder 1 and a transition arc surface 2, and the wire is wound on the surface of the cylinder 1 or the transition arc surface 2, figure 2 The wire 3 shown in is the wire that leaves the reel after being drawn, and the wire 4 shown is the wire that is drawn into the wire. [0003] In the current drawing reel, the drawn wire and the reel have circumferential and axial relative sliding. The more serious circumferential relative sliding will cause d...
