Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0028] Reference Figure 1-4 As shown, a profile rolling discharging and cutting device is arranged on a frame 1 on an external machine platform. The frame 1 includes a side plate 11. The side plate 11 is provided with an opening 111. The opening 111 is relatively large in size so as to be suitable for profiles of various specifications to pass through.

[0029] The knife group 2 is a core component for cutting materials. The knife group 2 includes a fixed knife block 21 and a movable knife block 22. The fixed knife block 21 is fixed to the side plate 11. The fixed knife block 21 is provided with a fixed knife edge, and the movable knife block 22 is provided with a movable knife edge. The cross-sectional area of ​​the movable knife edge is slightly larger than the cross-sectional area of ​​the fixed knife edge, but the contour shape is consistent, and the contour shape corresponds to the cross-sectional shape of the profile formed by rolling;

[0030] The positioning assembly 3 includes five positioning seats 31 and eight positioning pins 32 fixed on the side plate 11. The five positioning seats 31 are arranged around the fixed knife block 21, two positioning seats 31 are arranged on the left and right sides, one positioning seat 31 is arranged at the bottom, and two positioning seats 31 are arranged on the top. The two top positioning seats 31 can not only be used to fix the fixed knife block 21, but also can be used to assist the reset positioning of the movable knife block 22. The positioning pins 32 are penetrated on the positioning seats 31 and abut against the four sides of the fixed knife block 21 to fix it on the frame 1. The fixed knife block 21 is a rectangular plate with four side surfaces, each side surface is provided with two positioning pins 32, and there are arranged on each of the four sides. The two locating pins 32 can make the adjustment more flexible when installing the fixed knife block 21 compared with the traditional slot or bolt fixing method.
