Abstract
The invention discloses a kind of Novel drawing machine drum, including the spool body being made up of substrate layer and be arranged on the hardened layer outside substrate layer, it is provided with transition zone between described substrate layer and hardened layer, described transition zone is that piano wire is made, described transition zone is to being welded on described substrate layer and hardened layer, the Rockwell hardness of described transition zone is more than the Rockwell hardness of described substrate layer, and the Rockwell hardness of described transition zone is less than the Rockwell hardness of described hardened layer.The present invention increases middle hardness transition zone, so that reel hardness has the process gradually stepped up, solves in the middle of when reel cylinder manufactures without transition zone the flaky problem of reel casehardening layer appearance in use.
Description
Technical field
The present invention relates to a kind of Novel drawing machine drum, belong to Steel Wire Products Industry wire drawing and produce equipment.
Background technology
For ensureing that the mandrel surface directly contacted with steel wire has enough hardness, existing drawing block manufacture to be directly to exist
Spray coating metal ceramic coating on Substrate basis, but owing to the hardness of base material hardness and outer layer differs relatively big, reel is actually used
In, casehardening layer easily produces peeling phenomenon.
Summary of the invention
It is an object of the invention to provide a kind of Novel drawing machine drum, it is possible to improve the problem that prior art exists, increase
Add middle hardness transition zone, so that reel hardness has a process gradually stepped up, solve in the middle of when reel cylinder manufactures without transition zone
And reel casehardening layer holds flaky problem in use.
The present invention is achieved through the following technical solutions:
A kind of Novel drawing machine drum, including the spool body being made up of substrate layer and be arranged on the hardening outside substrate layer
Layer, is provided with transition zone between described substrate layer and hardened layer, and described transition zone is that piano wire is made, described transition zone butt welding
On described substrate layer and hardened layer, the Rockwell hardness of described transition zone is more than the Rockwell hardness of described substrate layer, described transition
The Rockwell hardness of layer is less than the Rockwell hardness of described hardened layer.
In wire drawing machine drawing process, reel is slided the frictional force brought by the huge pulling capacity of wire drawing machine and steel wire,
Rigorous service condition, accordingly, it would be desirable to arrange the casehardening layer that hardness is bigger, the present invention uses Rockwell hardness HRC from inside to outside
The structure being gradually increased so that the hardness of drawing block realizes gradually transition from inside to outside, in carrying out drawing process, energy
Enough be prevented effectively from due between hardened layer and substrate layer hardness have big difference cause hardened layer easily under pulling capacity effect occur
The phenomenon come off；Simultaneously as Rockwell hardness gradually expands, so that the vibrations that reel produces in drawing process are by gradually
Absorb, and then make whole reel have the effect of certain shock-absorbing damping so that it is more there is stability.
Further, for the present invention is better achieved, the thickness h of described transition zone is 2.5mm.
Further, for the present invention is better achieved, the thickness H of described hardened layer is 0.3mm, and described hardened layer is carbonization
Tungsten is made, and described substrate layer is that spheroidal graphite cast-iron is made.
Further, for the present invention is better achieved, described substrate layer outer wall is provided with along substrate layer circumferentially disposed
Groove, described transition zone is arranged in described groove.
Further, for the present invention is better achieved, described substrate layer outer wall being provided with curved corners, described groove prolongs
Extend in the middle part of described curved corners.
The present invention compared with prior art, has the advantages that
(1) when solving the work of existing reel, cementation zone holds flaky problem；
(2) steel wire can produce vibrations when high speed drawing, and reel hardness is gradually incremented by structure can play shock-absorbing functions very well.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to
This.
As it is shown in figure 1, the invention discloses a kind of Novel drawing machine drum, including the reel being made up of substrate layer 101 originally
Body and be arranged on the hardened layer 102 outside substrate layer 101, is provided with transition zone between described substrate layer 101 and hardened layer 103
102, described transition zone 102 is made for piano wire, described transition zone 102 to being welded on described substrate layer 101 and hardened layer 103,
The Rockwell hardness of described transition zone 102 is more than the Rockwell hardness of described substrate layer 101, and the Rockwell hardness of described transition zone 102 is little
Rockwell hardness in described hardened layer 103.
As preferably, in the present embodiment, for the present invention is better achieved, the thickness h of described transition zone 102 is 2.5mm.Institute
The thickness H stating hardened layer 103 is 0.3mm, and described hardened layer is that tungsten carbide is made, and described substrate layer 101 is made for spheroidal graphite cast-iron.
Owing to the Rockwell hardness HRC of spheroidal graphite cast-iron FCD45 is generally less than HRC40, in reel manufacture process, increase by one layer
Hardness transition zone, the piano wire that butt welding 2.5mm is thick, the Rockwell hardness of piano wire is generally about HRC55, and tungsten carbide wc material
Rockwell hardness generally individually more than HRC62, the Rockwell hardness being gradually increased, it is possible to make the hardness of reel have certain level,
It is not easy impaired during use；
In the present embodiment, qin thick for 2.5mm about first one layer of hardness HRC55 of butt welding on the basis of reel substrate layer FCD450
Steel wire, sprays one layer of hardness the most again more than the WC layer that HRC62 thickness is 0.3mm.
In order to make reel structure compacter, in the present embodiment, it is preferable that be provided with on described substrate layer 101 outer wall
Along the groove that substrate layer 101 is circumferentially disposed, described transition zone 102 is arranged in described groove.By transition zone 102 is arranged on
In groove, it is possible to avoid transition zone 102 under External Force Acting to come off, improve the stability of reel.
It is further preferred that be provided with curved corners 104 on described substrate layer 101 outer wall, described groove extends to described
In the middle part of curved corners 104.Owing to reel is in drawing process, the friction that its outer wall is slided by pulling capacity and the steel wire of wire drawing machine
Power, by arranging curved corners 104, it is possible to forms the sliding surface that steel wire slides, makes to be subject in reel curved corners 104 segment set
Power, owing to being also provided with transition zone 102 and hardened layer 103 on curved corners 104, it is possible to make its structure more stable, uses the longevity
Order longer.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
