Select in dynamic and automatic three kinds of modes.Rolled thread cold rolling technique is a kind of advanced without machining, can effectively improve workpiece
Inherent and surface quality, plus the radial compressive stress that man-hour produces can significantly improve the fatigue strength and torsional strength of workpiece, be
A kind of efficient, energy-conservation, the ideal technology of low consumption.
In the prior art, screw-rolling machine carries out rolled thread to product using two rolled thread wheel discs, and rolled thread wheel disc directly rotates peace
Loaded on support, and in order to prevent the mixture of metal fillings produced by rolled thread and lubricating fluid from dropping in the roller bearing of rolled thread wheel disc
Interior, the gap between rolled thread wheel disc and support is little as far as possible.But, if gap is too small, between rolled thread wheel disc and support
Frictional force is excessive, easily reduces the service life of rolled thread wheel disc, and maintenance rate is high, if gap is excessive, is easily accessible debris, rapid wear
Bad rolled thread wheel disc or roller bearing, affect machining accuracy, and maintenance rate is high.
The content of the invention
The utility model purpose is to provide a kind of screw-rolling machine rolled thread wheel disc, by using the structure, reduces cylindrical die roll
The maintenance rate of disk, extends the service life of rolled thread wheel disc.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of screw-rolling machine rolled thread wheel disc, including this
Body, the body is in hollow circular cylinder structure, and the body middle part is provided with rotating shaft installing hole, and the body outer edge surface is provided with multiple
Several rolled thread are raised；At least two snakelike oil guide grooves, the snakelike oil guide groove are further respectively had on the end face at the body two ends
The side of the rotating shaft installing hole is arranged at, the two ends of the snakelike oil guide groove are connected respectively with the outer edge surface of the body.
In above-mentioned technical proposal, two snakelike oil guide grooves are respectively equipped with the end face at the body two ends, two snakelike to lead
Oil groove is respectively arranged at the both sides of the rotating shaft installing hole, and two snakelike oil guide grooves are arranged in parallel, per snake described in bar
Shape oil guide groove is arranged at the middle part between rotating shaft installing hole and body outer edge surface.
In above-mentioned technical proposal, the section semicircular in shape of the snakelike oil guide groove.
In above-mentioned technical proposal, the depth of the snakelike oil guide groove is 2 ㎜～8 ㎜.
Because above-mentioned technical proposal is used, the utility model has compared with prior art following advantages：
1. the two ends of body are rotated in the utility model and be installed in mounting bracket, and at rolled thread wheel disc body two ends
Two snakelike oil guide grooves are respectively equipped with end face, the section semicircular in shape of snakelike oil guide groove, depth is 2 ㎜～8 ㎜, by snakelike
The setting of oil guide groove, can make body during rolled thread, and lubricating oil enters into body and mounting bracket by snakelike oil guide groove
Between gap in, lubricating oil is uniformly coated between body and mounting bracket using the rotation of body, play profit
Sliding effect, meanwhile, the section of snakelike oil guide groove is arranged to into semicircle, it is easy to debris to drop in snakelike oil guide groove and is directly turned
Dynamic centrifugal force throws away；
2. the utility model simple structure, it is easy to accomplish.
Description of the drawings
Fig. 1 is the structural representation in the utility model embodiment one；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the cross section structure schematic diagram of snakelike oil guide groove in the utility model embodiment one.
Wherein：1st, body；2nd, rotating shaft installing hole；3rd, rolled thread is raised；4th, snakelike oil guide groove.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment one：Referring to shown in Fig. 1～3, a kind of screw-rolling machine rolled thread wheel disc, including body 1, during the body 1 is in
Hollow cylinder structure, the middle part of the body 1 is provided with rotating shaft installing hole 2, and it is raised that the outer edge surface of the body 1 is provided with plural bar rolled thread
3；At least two snakelike oil guide grooves 4 are further respectively had on the end face at the two ends of the body 1, the snakelike oil guide groove 4 is arranged at institute
The side of rotating shaft installing hole 2 is stated, the two ends of the snakelike oil guide groove 4 are connected respectively with the outer edge surface of the body 1.
Referring to shown in Fig. 1～3, two snakelike oil guide grooves 4 are respectively equipped with the end face at the two ends of the body 1, two snakelike
Oil guide groove 4 is respectively arranged at the both sides of the rotating shaft installing hole 2, and two snakelike oil guide grooves 4 are arranged in parallel, the institute per bar
State the middle part that snakelike oil guide groove 4 is arranged between rotating shaft installing hole 2 and the outer edge surface of body 1.
It is shown in Figure 3, the section semicircular in shape of the snakelike oil guide groove 4, the depth of the snakelike oil guide groove 4 is 5 ㎜.
In the present embodiment, the two ends of body 1 are directly mounted in mounting bracket so as to which rolling is installed on mounting bracket
On, and in order to the debris for preventing rolled thread plus produced by man-hour drop in rotating shaft installing hole 2, body 1 is destroyed, axiality is affected,
Therefore the gap between the two ends of body 1 and mounting bracket is reduced as far as possible.For the ease of the lubrication of lubricating fluid, two are arranged
Snakelike oil guide groove 4, and snakelike oil guide groove 4 is arranged at into the both sides of rotating shaft installing hole 2, body 1 adds man-hour in rolled thread, lubricating fluid or
Lubricating oil is flowed in snakelike oil guide groove 4, using the rotation of body 1, lubricating fluid or lubricating oil is brushed completely in body 1 and peace
Between dress support, to playing lubrication between body 1 and mounting bracket.And in the present embodiment, cutting snakelike oil guide groove 4
Face is set to semicircle, and compared with square structure, the flowing of lubricating fluid or lubricating oil is more smooth, by the depth of snakelike oil guide groove 4
Degree is set to 5 ㎜, because the metal fillings produced in rolled thread is generally less than 3 ㎜, or more than 10 ㎜, takes median, little metal
Bits smoothly by snakelike oil guide groove 4, and can be washed away by lubricating oil or lubricating oil, while also can be by these in rotation process
Debris throw away, and will not be stacked in snakelike oil guide groove 4, it is ensured that lubricating fluid or lubricating oil normal through.
In the present embodiment, snakelike oil guide groove 4 is set, lubricating oil or lubricating fluid can be made by snakelike oil guide groove 4
Time relative prolongation, makes lubricating fluid or lubricating oil be uniformly coated between body 1 and mounting bracket, it is ensured that lubricant effect.
