The bar 2 sequentially passes through the gaps among the first roller 3, the second roller 4, the third roller 5 and the extrusion wheel 10, so that the bar 2 is rolled for three times and moves forwards along the surface of the extrusion wheel 10. The extrusion wheel 10 and the first roller 3, the second roller 4 and the third roller 5 form a pack rolling curved channel, and the bar 2 changes the moving direction under the action of the three rollers while passing through three times of rolling, so that the bar 2 is attached to the surface of the extrusion wheel 10 to be changed into a curved shape. In other embodiments, two rollers, or more than four rollers, may be provided. After the bar 2 is rolled by the roller pair, the extrusion wheel 10 and three rollers (four times of rolling), a large amount of shaping deformation is accumulated.
Because the extrusion wheel 10 and the planetary rollers have coordinated speeds, the bar 2 can pass through all the deformation channels at a uniform speed, and the effect of continuous processing is achieved. Because a plurality of rollers are arranged to be matched with the extrusion wheel 10, the power required by continuous processing is ensured. In the primary extrusion process, the bar 2 passes through various deformation channels, so that the reinforcing effect of the bar 2 is greatly improved. The extrusion wheel 10 is arranged on the extrusion wheel shaft 9, and the extrusion wheel 10 is connected with the extrusion wheel shaft 9 through a connecting key 11.
The diameters of the first roller 3, the second roller 4 and the third roller 5 are the same, and the diameter of the extrusion wheel 10 is larger than the diameters of the first roller 3, the second roller 4 and the third roller 5. The included angle formed by the connecting line of the circle center of the first roller and the circle center of the extrusion wheel and the connecting line of the circle center of the second roller and the circle center of the extrusion wheel is equal to the included angle formed by the connecting line of the circle center of the second roller and the circle center of the extrusion wheel and the connecting line of the circle center of the third roller and the circle center of the extrusion wheel, and in the embodiment, the included angles are all 30 degrees; and the first roller 3, the second roller 4, the third roller 5 and the extrusion wheel 10 have the same distance. In other embodiments, the position of the roller can be adjusted according to the process requirements, and the position of each planet wheel is adjusted, so that the deformation of each rolling is adjusted, the friction force can be increased while the rolling deformation is increased, and the feeding force of the feeding (namely the bar 2) is improved.
The extrusion die 6 comprises an arc-shaped channel and a straight-line channel, and a tangent line of the intersection position of the arc-shaped channel and the straight-line channel is perpendicular to the straight-line channel. The arc-shaped channel and the linear channel form an extrusion cavity, one side surface of the inlet of the extrusion cavity is arc-shaped, the other side of the inlet of the extrusion cavity is a bottom plane, the arc-shaped channel and the bottom plane are matched with the surface of the extrusion wheel to form a shearing bending channel, and the equal channel angular extrusion of one pass is finished through the shearing bending channel. The bar 2 turns approximately 90 degrees in the process of entering the linear channel from the arc channel, and the bar 2 is subjected to severe approximate shearing deformation in the process of passing the shearing and bending channel, so that a large amount of plastic deformation quantity is accumulated on the bar 2. The bar 2 passes through the shearing bending channel, which is equivalent to finish equal channel angular extrusion in one pass, and the lap rolling bending channel is connected with the shearing bending channel in sequence.
In this embodiment, the extrusion die 6 is located downstream of the third roller 5, the arc-shaped channel is arranged adjacent to the extrusion wheel 10, and the bar 2 is rolled by the extrusion wheel 10 and the third roller 5 and then enters the arc-shaped channel. One side arc surface of the arc channel is the surface of the extrusion wheel 10, and the other side arc surface is arranged on the extrusion die 6. That is, extrusion die 6 is placed beside extrusion wheel 10, and the arc passageway is formed jointly by the arcwall face on partly surface and the extrusion die 6 of extrusion wheel 10, and this also makes rod 2 contact with extrusion wheel 10 all the time when getting into the arc passageway, and extrusion wheel 10 can provide the power that advances for rod 2, and the rod 2 of being convenient for gets into extrusion die 6 in, provides more power for rod 2 follows the arc passageway and gets into the straight line passageway as far as.
The inlet of the reducing drawing die 7 is connected with the outlet of the extrusion die 6. Extrusion die 6 has a cuboid recess on the right-hand member face, and the appearance of reducing drawing die 7 is the cuboid, and reducing drawing die 7 inlays in extrusion die 6's cuboid recess. The diameter of the outlet of the reducing-drawing die 7 is smaller than the diameter of the inlet, thereby completing the reducing process of the rod 2.

After the bar 2 contacts the rotating extrusion wheel 10, under the action of friction force between the planetary roller set, the extrusion wheel 10, the extrusion wheel groove 8 and the bar 2, the bar 2 enters the overlapping rolling bending channel, so that the bar 2 accumulates a large plastic deformation amount. Extrusion die 6 sets up the right side at extrusion wheel 10, and extrusion die 6 is located the below of third roll 5 simultaneously, and extrusion die 6's a side arcwall face, straight line passageway and extrusion wheel 10 partly surface cooperate and have formed shearing crooked passageway, behind the rod 2 through the roll-over crooked passageway, under the driving action of frictional force, during rod 2 was pushed the shearing crooked passageway immediately, violent approximate shear deformation has taken place in extrusion die 6's die cavity corner for rod 2 has accumulated a large amount of plastic deformation volume. After passing through the shearing and bending channel, the bar 2 finally passes through a reducing and drawing die 7, and the reducing and extruding process is completed under the action of the reducing and drawing die 7.
In the whole process flow, the folding bending channel, the shearing bending channel and the reducing extrusion channel are connected in sequence; through the extrusion process once, the bar passes through three kinds of extrusion die cavities in succession, and bar 2 extrusion efficiency improves greatly. That is, after the bar 2 completes the strain accumulation processes such as multi-round rolling (i.e. accumulation and pack rolling), equal channel angular extrusion, continuous extrusion and the like, the bar is drawn in the cavity of the reducing drawing die 7, so that a set of continuous extrusion and strengthening processing processes of the bar 2 with the required specification is completed.
