Description
Technical field
The utility model relates to drawing block structure, particularly relates to a kind of without circumference relative sliding electric wire metal wire rod drawing block structure.
Background technology
Wire drawing machine is the capital equipment that all kinds of metal wire rod draws, and drawing block is the critical piece of wire drawing machine.During the drawing block drawing of current routine, there is relative sliding in wire rod and reel, and more serious relative sliding can produce the defects such as scuffing, speckle to wire surface, even more serious during the relatively low non-ferrous metal wire rod such as copper, aluminium of particularly drawing hardness.
Utility model content
The purpose of this utility model is the defect overcoming prior art, a kind of electric wire metal wire rod drawing block structure is provided, design the drawing block structure without circumference relative sliding, cancel the excessive arc surface of reel, move with raising on wire rod that pulley realizes on reel, drawing block after improvement can eliminate circumference relative sliding, reduces the defect because relative sliding brings to wire surface.
The technical solution adopted in the utility model is:
A kind of electric wire metal wire rod drawing block structure, comprise body, described body becomes straight hollow cylinder, is provided with pipe spreader, has pulley in the arranged outside of described body at described body interior center position.
Further, the quantity of described pulley is 6 ~ 8.
Further, described pulley is 0.3 ~ 1mm apart from the distance of described body outer surface.
Further, described pulley is uniformly distributed along described body outer surface.
Further, the setting height(from bottom) of described pulley is along described body direction of rotation uniform lift.
Further, described first pulley is consistent with the diameter of metal wire rod with the setting height(from bottom) difference between last pulley.
Further, described pulley is magnetic suspension bearing.
Further, the outer surface of described body is coated with metal ceramic wear-resisting material.
The beneficial effects of the utility model are:
Same in traditional drawing block structure, there is the face of cylinder and excessive arc surface.Reel rotates with constant speed, and wire rod first accumulates on the face of cylinder, and be called long-pending line, wire rod and reel contact frictional resistance are that wire rod provides required pulling capacity, also make on its position maintained when entering reel.Along with wire rod is successively wound up on reel, the most backward arc surface is wound around arrangement, and the diameter often enclosed progressively becomes large, and inlet wire speed increases, and now causes and there is gap into and out of wire velocity.Under the effect of pulling capacity, the wire rod on reel arc surface to produce upwards and to the component in spool axis direction at its contact point.When upwards component overcomes the frictional force of long-pending line on reel, long-pending line along arc surface and face of cylinder upward sliding, can be follow-up inlet wire vacating space, is axial relative sliding, and the wire rod on arc surface can zoom in circle footpath until enter the face of cylinder.Now by the circumference relative sliding of wire rod on arc surface, poor with the circle footpath of eliminating wire rod on the face of cylinder and arc surface.Relative sliding can maintain stable state, sometimes by the impact of lubrication, mandrel surface roughness and pulling capacity change, can there is unexpected sliding phenomenon in long-pending line, shrinks in the long-pending coil footpath short time on arc surface to the reel face of cylinder, inlet wire stops instantaneously, until recover stress balance.Now main generation circumference relative sliding on reel, and cause friction and pulling capacity moment significantly to change, wire surface is produced to the defects such as scuffing, speckle, also can have a negative impact to mechanical device is stressed.For less demanding occasion, the negative effect that relative sliding causes is negligible, but for requiring higher occasion, particularly requires the drawing in stable as-drawn or finished product stage, and eliminating circumference relative sliding is need the main problem paid close attention to.
In the utility model, adopt right cylindrical cylinder in drawing block structure and with the use of 6 ~ 8 pulleys, and pulley is arranged along reel direction of rotation uniform lift.When reel is rotated counterclockwise, wire rod enters initial pulley position along mandrel surface, enters into second pulley successively, until when wire rod arrives last pulley successively, wire rod is raised the height of a gauge or diameter of wire, for inlet wire leaves space.Along with reel continues to rotate, inlet wire is constantly wound up into reel, and is constantly raised, and reel accumulates, leaves reel finally by outlet, forms circulation.The utility model eliminates the arc surface structure of original reel, therefore the wire rod long-pending line of winding on the face of cylinder all the time, and every loop diameter is identical, so there is not circumference relative sliding, reduces the defect because relative sliding brings to wire surface.Meanwhile, current reel working face generally all carries out spraying or built-up welding high hardness material, and the roughness on the face of cylinder can control in higher level, but be subject to processing the restriction of condition, the roughness of arc surface controls much lower, and the design eliminates arc surface, is therefore more conducive to reel processing.

Detailed description of the invention
In order to make the advantage of the purpose of this utility model and technical scheme clearly understand, below in conjunction with accompanying drawing and example, the utility model is further elaborated.
As shown in Figure 1, same in traditional drawing block structure, there is the face of cylinder 1 and excessive arc surface 2.Reel rotates with constant speed, and wire rod first accumulates on the face of cylinder, is called long-pending line, and wire rod 3 and reel contact frictional resistance are that wire rod 3 provides required pulling capacity, also make on its position maintained when entering reel.Along with wire rod 3 is successively wound up on reel, the most backward arc surface 2 is wound around arrangement, and the diameter often enclosed progressively becomes large, and inlet wire speed increases, and now causes and there is gap into and out of wire rod 3 speed.Under the effect of pulling capacity, the wire rod 3 on reel arc surface 2 to produce upwards and to the component in spool axis direction at its contact point.When upwards component overcomes the frictional force of long-pending line on reel, long-pending line along arc surface 2 and the face of cylinder 1 upward sliding, can be follow-up inlet wire vacating space, is axial relative sliding, and the wire rod on arc surface 2 can zoom in circle footpath until enter the face of cylinder 1.By the impact of lubrication, mandrel surface roughness and pulling capacity change, can there is unexpected sliding phenomenon in long-pending line, and shrink to the reel face of cylinder in the long-pending coil footpath short time on arc surface 2, inlet wire stops instantaneously, until recover stress balance.Now main generation circumference relative sliding on reel, and cause friction and pulling capacity moment significantly to change, wire surface is produced to the defects such as scuffing, speckle, also can have a negative impact to mechanical device is stressed.
As shown in Figures 2 and 3, a kind of electric wire metal wire rod drawing block structure, comprises body 4, the straight hollow cylinder of described body 4 one-tenth, is provided with pipe spreader 5, has pulley 6 in the arranged outside of described body 4 at described body 4 inner hub location place.The quantity of described pulley 6 is 6 ~ only.Described pulley 6 is 0.3 ~ 1mm apart from the distance of described body 4 outer surface.Described pulley 6 is uniformly distributed along described body 4 outer surface.The setting height(from bottom) of described pulley 6 is along described body 4 direction of rotation uniform lift.Described first pulley 6 is consistent with the diameter of metal wire rod with the setting height(from bottom) difference between last pulley 6.Described pulley 6 is described magnetic suspension bearing, and when being applicable to more speed drawing, it has, and limit speed is high, frictional dissipation is little, long service life and precision advantages of higher.The outer surface of described body 4 is coated with metal ceramic wear-resisting material, and production efficiency is high, long service life.
Be uniformly distributed for the wire rod of diameter 3 mm, 6 pulleys, when reel is rotated counterclockwise, wire rod enters initial pulley position along mandrel surface, and enter into second pulley successively, now wire rod raises 0.6 mm along spool axis direction.When wire rod arrives the 6th pulley successively, wire rod is raised 3 mm, for inlet wire leaves space.Along with reel continues to rotate, inlet wire is constantly wound up into reel, and is constantly raised, and reel accumulates, leaves reel finally by outlet, forms circulation.
The utility model eliminates the arc surface structure of original reel, therefore the wire rod long-pending line of winding on the face of cylinder all the time, and every loop diameter is identical, so there is not circumference relative sliding, reduces the defect because relative sliding brings to wire surface.Meanwhile, current reel working face generally all carries out spraying or built-up welding high hardness material, and the roughness on the face of cylinder can control in higher level, but be subject to processing the restriction of condition, the roughness of arc surface controls much lower, and the design eliminates arc surface, is therefore more conducive to reel processing.
