Embodiment 1
[0016] Such as Figure 1-Figure 2 As shown, an extrusion wheel of a continuous extrusion machine, the extrusion wheel 1 is provided with a circular groove 2 in the circumferential direction, and the extrusion wheel 1 is distributed along the circumferential direction with a plurality of grooves passing through the extrusion wheel 1. Cooling through hole 3, there is a distance H between the center line of the cooling through hole 3 and the bottom of the groove 2, and the center line of the cooling through hole 3 is perpendicular to the end face of the extrusion wheel, that is, the center line of the cooling through hole 3 and the extrusion wheel 1 The centerlines are parallel, and the end face of the extrusion wheel is provided with a pin hole 4 that does not go through the extrusion wheel 1 .
[0017] The diameter D of the cooling through hole 3 is 10 mm, the distance H between the center line of the cooling through hole 3 and the bottom of the groove is 28 mm, and the number ...
Embodiment 2
[0020] The structure and connection relationship of each part of the extrusion wheel of a continuous extrusion machine described in this embodiment are the same as those in Example 1, the difference is that the cooling through hole 3 is 15° from the axis of the extrusion wheel 1. °; the diameter of the cooling through hole 3 is 6 mm, the distance H from the centerline of the cooling through hole 3 to the bottom of the groove is 15 mm, and the number of cooling through holes 3 is 20; the number of the pin hole 4 is 1 ; The inner hole of the extrusion wheel is provided with circular arc grooves for installing transmission keys to transmit torque, the number of the circular arc grooves is 4-16, and the radius of the circular arc grooves is 4-20mm.
Embodiment 3
[0022] The structure and connection relationship of each part of the extrusion wheel of a continuous extrusion machine described in this embodiment are the same as those in Example 1, the difference is: the cooling through hole 3 is 30 degrees to the axis of the extrusion wheel 1 °; the diameter of the cooling through hole 3 is 15mm, the distance H between the centerline of the cooling through hole 3 and the bottom of the groove is 40mm, and the number of cooling through holes 3 is 8; the number of the pin holes 4 is 16 ; The inner hole of the squeeze wheel is provided with internal splines for torque transmission.
