Description
Technical field
The present invention relates to finishing fields, and in particular to cylindrical die roll renovation technique.
Background technique
Cylindrical die roll is a kind of tool that method on screw-rolling machine using metal plastic deformation rolls out screw thread.Cylindrical die roll by
It is needed to possess higher hardness and certain toughness in the characteristic (relying on rigidity roll-in screw thread) of its work.
Cylindrical die roll is in use for some time, it may appear that the phenomenon that tooth of cylindrical die roll is broken, the rolling only more renewed at this time
Silk wheel, but since the price of rolled thread is higher, while purchasing and needing certain period, so the production to enterprise causes centainly
Puzzlement.
Summary of the invention
It in view of the above drawbacks of the prior art, can be with it is an object of the invention to provide a kind of cylindrical die roll renovation technique
The cylindrical die roll of broken teeth is repaired, cylindrical die roll is allowed to continue normally to use.
It is realized the purpose of the present invention is technical solution in this way:
A kind of cylindrical die roll renovation technique, comprising the following steps:
S1, the cylindrical die roll of damage is fixed；
S2, the range of the tooth of fracture is expanded to obtain by the place for damaging tooth on cylindrical die roll using tool and repairs area；
S3, it is punched in the reparation area of cylindrical die roll using drilling machine；
S4, area and other good areas will be repaired keep apart；
S5, filling molten metal to reparation area；
After S6, area to be repaired are cooling, obturator is cut as cylindrical die roll using cutting element.
Further, in the step S2, using tool along the cylindrical die roll of fracture tooth extension direction by tooth break it is disconnected from
And expands and repair area.
Further, in the step S3, when being punched using drilling machine, the center of circle of cylindrical die roll is directed toward in the direction of hole.
Further, in the step S3, the diameter in hole increases with the increase of depth.
It further, further include cylindrical die roll heat pre-treatment before the step S5.
Further, the cylindrical die roll heat pre-treatment is to be heated using high frequency heating coil to restoring area.
Further, in the step S3, the installation lock chamber among cylindrical die roll is punched using the hole that drilling machine is beaten；Hole
Underfill metal carbon dust.
Further, in the step S5, after filling molten metal, restoring area is added using high frequency heating coil
Heat treatment.
Further, in the step S4, restoring area and other good areas is separated and use metal carbon dust
Fill the gap between tooth and tooth；
The metal carbon dust is the mixture of metal powder and carbon dust.
Further, after the step S6, it is also necessary to carry out full annealing processing to cylindrical die roll, then be quenched.
By adopting the above-described technical solution, the present invention has the advantage that:
It is repaired by the region amplification of original broken teeth of part cylindrical die roll, so that the metal of the rear addition after repairing and rolling
Silk wheel whole fusion degree and contact area increase, the metal and the original metal of rolled thread after can making reparation in this way
Degree of integration is higher, from make using when be not in separation.
The metal repaired and the original metal connection intensity of cylindrical die roll can be made higher by drilling machine punching.
Other advantages, target and feature of the invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.Target and other advantages of the invention can be wanted by following specification and right
Book is sought to be achieved and obtained.
Specific embodiment
Below with reference to the invention will be further described with embodiment.
Embodiment:
A kind of cylindrical die roll renovation technique, comprising the following steps:
S1, the cylindrical die roll of damage is fixed；
S2, tooth is broken disconnected to obtain repairing area along the tooth extension direction of the cylindrical die roll of fracture using tool；
The bonding strength for repairing metal and original metal can be increased by expanding reparation area first, be prolonged by only destroying fracture tooth
The region of exhibition is not destroyed elsewhere, it is ensured that the intensity of tooth elsewhere.
S3, it is punched in the reparation area of cylindrical die roll using drilling machine；The center of circle of cylindrical die roll is directed toward in the direction of hole, hole it is straight
Diameter increases with the increase of depth, is connected to the installation lock chamber among hole and cylindrical die roll；The underfill metal carbon in hole
Powder.
Cylindrical die roll is squeezed other materials when in use, and the power that the tooth on all cylindrical die rolls receives is directed to justify
The heart can make the only effect by unidirectional force as far as possible of the metal after repairing, improve and repair metal by the way that the center of circle is also directed toward in hole
Durable tolerance and reduce with original metal be detached from a possibility that.
It is the gold in order to when subsequent filling molten metal by the way that hole to be connected to the installation lock chamber of cylindrical die roll
Category liquid can thoroughly fill up entire hole and not leave a void；Stream of the molten metal in hole can be slowed down by metal carbon dust
Dynamic speed reduces the amount that molten metal flows to the installation lock chamber of cylindrical die roll.
S4, area and other good areas will be repaired keep apart；Restoring area is separated with other good areas and is used
Metal carbon dust fills the gap between tooth and tooth；
The metal carbon dust is the mixture of metal powder and carbon dust.
Metal carbon dust and can with the flowing velocity of barrier metal liquid it is also possible that metal has certain mobility, thus
Allow metal to be fully filled with restoring area and does not leave bubble.
S5, restoring area is heated using high frequency heating coil, then fills molten metal to reparation area；Fill molten metal
Afterwards, high frequency heating coil is reused to heat restoring area.Molten metal can be made to be unlikely to cooling so too fast
So that the gap etc. of restoring area can not be filled up completely full, while it is also possible that bubble in restoring area by molten metal
It can run out of.
After S6, area to be repaired are cooling, obturator is cut as cylindrical die roll using cutting element；Cylindrical die roll is carried out again complete
Annealing, then be quenched.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered in the present invention
Scope of the claims in.
