[0019] The present invention provides a metal bar hot extrusion chain plate type traction machine as Figures 1-3 shown, which includes a support bottom plate 1. Four mounting vertical rods 2 are fixedly arranged on the upper surface of the support bottom plate 1. Mounting collar rings 3 are fixedly connected to the bottoms of the outer sides of the four mounting vertical rods 2. A first chain plate conveyor belt 4 is installed between the four mounting collar rings 3. Connecting collar rings 6 are sleeved on the tops of the outer sides of the four mounting vertical rods 2. A second chain plate conveyor belt 8 is fixedly installed between the four connecting collar rings 6. The first chain plate conveyor belt 4 and the second chain plate conveyor belt 8 are connected by an adjusting assembly 5. A distance marking assembly 7 is arranged near one of the connecting collar rings 6 of the first chain plate conveyor belt 4. Connecting top plates 9 are fixedly connected between the tops of every two oppositely positioned mounting vertical rods 2.

[0020] As Figures 1-3 shown, for the metal bar hot extrusion chain plate type traction machine, the adjusting assembly 5 includes four electric cylinders 501. The four electric cylinders 501 are all installed on the outer side of the first chain plate conveyor belt 4. Four support connecting plates 502 are fixedly connected to the second chain plate conveyor belt 8 near the electric cylinders 501. The output ends of the four electric cylinders 501 are fixedly connected to the oppositely positioned support connecting plates 502. The distance marking assembly 7 includes a dimension marking plate 701. A marking bottom plate 702 is fixedly connected to the lower surface of the connecting collar ring 6 near the dimension marking plate 701.
