Along respective length of run direction, wherein one end is rolling starting point to tool, and the other end is forming ends, the width of the rolling starting point
Less than the width of forming ends, wherein side is pre-forming area along respective width direction for upper mold and lower mold, and the other side is molding
Area, pre-forming area and shaping area pass through the cutter being arranged on forming ends and separate；Upper mold and lower mold forming ends it is preforming
The side that area and shaping area are located remotely from each other is equipped with non-active area, forming ends unless the width of active region to be processed shaft member length
One times or more；The type groove for rolling shaft member is equipped on the pre-forming area and shaping area.
The upper mold and lower mold pass through bolt and fix with roll as a preferred technical solution,.
By adopting the above-described technical solution, the utility model have it is following prominent the utility model has the advantages that
1, it rolls Step Shaft by improved mold to link up the processing of front and back shaft member, so will not in process
There is waste material head, avoids the waste of steel, reduce production cost.
2, the discontinuous production technology rolled after conventional be initially switched off has been overturned by the improvement of mold, has realized whole round steel
Serialization rolling, rolling efficiency promote several times.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of Step Shaft is without material head continuous rolling mold, including is separately mounted on rolled with roller wedge topping roll and bottom roll
And the identical upper mold of structure and lower mold, upper mold and lower mold pass through bolt and fix with roll.
As shown in Fig. 2, wherein one end is rolling starting point 2 along respective length of run direction for upper mold and lower mold, it is another
End is forming ends 3, and the width of rolling starting point 2 is less than the width of forming ends 3.Upper mold and lower mold along respective width direction its
Middle side is pre-forming area 5, and the other side is shaping area 6, and pre-forming area 5 and shaping area 6 pass through the cutter being arranged on forming ends 3
4 separate.
The side that the pre-forming area 5 and shaping area 6 of upper mold and lower mold forming ends 3 are located remotely from each other is equipped with non-active area
9, forming ends 3 unless active region 9 width by one times or more of processing shaft member length.If upper mold and lower mold forming ends
3 length is less than above-mentioned requirements, then is unable to get preforming processing effect.
As shown in Figure 3,4, the type groove 7 for rolling shaft member is equipped on the pre-forming area 5 and shaping area 6.
As shown in Fig. 2, the range of broadening angle 1 is 7 ° -9 ° on the upper mold and lower mold, the range of this broadening angle 1
1 angle of broadening angle compared to existing mold reduces, and the size for reducing rolling 2 broadening angle 1 of starting point can be such that shaft member is easier into
Type.As shown in figure 4, the range of forming angle 8 is 35 ° -45 ° on upper mold and lower mold, the range of this forming angle 8 is compared to existing
There is 8 angle of forming angle of mold to increase, the purpose for increasing broadening angle 1 is the thrust for making the increase of its thrust offset back round steel, from
And adapt to whole round steel serialization rolling.
It is described further below with reference to pair the rolling method of Fig. 1,2,3,4,5,6:
In the operation of rolling, whole Zhi Yuangang is entered between upper mold and lower mold by driving means such as cylinders, upper and lower two
Continuous and local deformation occurs for round steel under a mold collective effect, when rolling for the first time, upper mold pre-forming area 5 and lower mold in advance at
Under the mating reaction of both type areas 5, it is preforming to complete first shaft member head end；Continue to press on round steel, make first shaft member head end into
Enter the shaping area 6 of upper mold and the shaping area 6 of lower mold, in the mating reaction of both upper mold shaping area 6 and lower mold shaping area 6
Under, complete that first shaft member is integrally formed and second shaft member head end is preforming, as shown in figure 5, passing through after shaft member roll forming
Cutter 4 on cutter 4 and lower mold on upper mold cooperates the end end of first shaft member and second shaft member head end end
Head cutting separation.
When shaft member is by B-B, as shown in fig. 6, the pre-forming area 5 at B-B, realizes the part of second shaft member head end
It rolls, rolling of first shaft member in addition to head end is realized in the shaping area 6 at B-B.
When shaft member is by A-A, as shown in figure 5, the pre-forming area 5 at A-A, complete second shaft member head end in advance at
Type, molding of first shaft member in addition to head end is completed in the shaping area 6 at A-A, since the head end of first shaft member is rolled for the first time
Roll forming when processed, so rolling is not played the role of to the head end of first shaft member in shaping area, rises when rolling for second
To be retainer effect.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
