Two rollers（8）Circumferential surface offer and the corresponding cavity of cylinder part, first gear（2）With third gear（7）Engagement,
Second gear（10）With the 4th gear（9）Engagement.
As a kind of preferred embodiment：First roller（3）The side of cavity be provided with and the first roller（3）Axis into γ degree
Chamfering, the first roller（3）The opposite side of cavity be provided with and the first roller（3）Axis into 180+ γ degree chamfering；Second
Roller（8）The side of cavity be provided with and the second roller（8）Axis into the chamfering of γ degree, the second roller（8）Cavity it is another
Side is provided with and the second roller（8）Axis into the chamfering of 180+ γ degree, γ is between 25 degree to 35 degree.
As a kind of preferred embodiment：First roller（3）Cavity section it is in the arc-shaped, arc-shaped correspondence arc length is 5
π/6, the second roller（8）Cavity section it is in the arc-shaped, arc-shaped correspondence arc length is 5 π/6.
The beneficial effects of the utility model are：The utility model opens up overlap chamfering at roller roller side, relative to without winged
The radial-sealing roller of side slot is extruded into for shape, is equivalent to and is played the role of metal " radially shunting ", so as to effectively reduce
Radial compression power suffered by roller, so as to effectively improve the service life of roller and entire roll extrusion device；Two rollers are spelled
The roller for being formed complete shape shape after dress at the roll gap for being also easy to produce overlap squeezes flash gutters, and relative to triangle roller squeeze it is winged
Radial compression power is less suffered by the slot of side.

Specific embodiment
The utility model mainly by two synchronized counter-rotational first roller, 3 and second rollers 8 to cylinder blank into
Cylinder blank 6 is through on punch-pin by row Roll-extrusion forming, and progress roller is extruded between being pressed into two idler wheels by and then by hydraulic press
Type, as shown in Figure 3.As shown in Figure 1, a kind of Roll-extrusion forming device of cylinder part, the first roller 3 is pacified by the first connecting shaft 5
On bearing 1, the second roller 8 is mounted on by the second connecting shaft 11 on bearing 1,8 structure phase of the first roller 3 and the second roller
Together, the both ends of the first connecting shaft 5 connect first gear 2 and second gear 10 respectively, and the both ends of the second connecting shaft 11 connect respectively
The circumferential surface of 7 and the 4th gear 9 of third gear, the first roller 3 and the second roller 8 offers and the corresponding type of cylinder part
Chamber, first gear 2 and third gear 7 engage, and 10 and the 4th gear 9 of second gear engages.As shown in Fig. 2, the type of the first roller 3
The side of chamber is provided with the chamfering into γ degree with the axis of the first roller 3, and the opposite side of the cavity of the first roller 3 is provided with and the first roller
Wheel 3 axis into 180+ γ degree chamfering；Second roller（8）The side of cavity be provided with the axis of the second roller 8 into γ degree
Chamfering, the opposite side of the cavity of the second roller 8 is provided with the chamfering with the axis of the second roller 8 into 180+ γ degree.First roller 3
Cavity section it is in the arc-shaped, arc-shaped correspondence arc length is 5 π/6, and the section of the cavity of the second roller 8 is in the arc-shaped, circle
The correspondence arc length of arc is 5 π/6.In Fig. 3, γ+α=90 degree, for β between 1 degree of -5 degree, β is the start bit in order to determine chamfering
It puts, α is to determine γ angles size.Roller, which is squeezed during deflashing, the forming defects such as does not occur folding.
With reference to the stressing conditions on the first and second rollers roller side during the work time, by roller thickness is increased, at two
Roller flash gutters tip exterior is there are certain thickness enclosed region, so as to achieve the purpose that strengthen roller edge strength.
During roller squeezes, roller squeezes punch-pin and is moved downward under the action of hydraulic press, and cylinder blank is made in the thrust of punch-pin
The roller for curved surface flash gutters that there are two the bands formed with lower two rollers of entrance to squeeze type groove, carries out first of roller and is extruded into shape；First
After roller squeezes, the blank with curved surface overlap is rotated by 90 ° by manipulator to be again introduced into roller and squeezes type groove.After second roller squeezes, cylinder
Body blank outer wall overlap is eliminated, and completes the forming that cylinder blank roller squeezes part.
