[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A rolling guide mechanism for hot-rolled angle steel outlet, comprising a guide box 1, openings 2 are provided on both sides of the guide box 1, and adjustment mechanisms 3 are provided at both ends of the inner part of the guide box 1 close to the right opening 2, and the adjustment mechanism 3 comprises a shaft sleeve 301, a movable block 302 and an arc connecting rod 303; both ends of the inner part of the guide box 1 close to the right opening 2 are movably connected to the shaft sleeve 301 through a rotating shaft, the shaft sleeve 301 is fixedly connected to the middle part of the back of the movable block 302, and the arc connecting rod 303 is fixedly installed between both ends of the side of the movable block 302 close to the shaft sleeve 301; both ends of the side of the guide box 1 away from the movable block 302 are movably installed with rollers 6 through a rotating shaft, and the guide box 1 is provided with a guide block 7 between the movable block 302 and the roller 6;

[0027] In this embodiment, when in use, the rolled piece is fed in from the opening 2 on the right side of the guide box 1. If the angle of the rolled piece is too large during the feeding process, it will randomly touch the end of the movable block 302 on any side. A fixed seat 4 is provided on the outer side of the end of the movable block 302. The fixed seat 4 is welded and fixed to the guide box 1. The outer side of the end of the movable block 302 is blocked by the fixed seat 4 and will not be excessively stretched outward. Therefore, the rolled piece is guided by the movable block 302, thereby facilitating the rapid guidance of the rolled piece.

[0028] like Figure 3 As shown, the outer side of the end of the guide box 1 close to the two movable blocks 302 is provided with a fixed seat 4, and the middle of the two fixed seats 4 is penetrated with a through groove 5, and the two arc-shaped connecting rods 303 are respectively slidably connected with the through grooves 5 on both sides;

[0029] In this embodiment, when the workpiece slides to the other end of the movable block 302, the end of the workpiece will squeeze the movable block 302. After being pressed, the end of the movable block 302 close to the guide block 7 is stretched outward, and the stretched end of the movable block 302 drives the other end through the arc-shaped connecting rod 303 to push the rear section of the workpiece toward the middle, so that the workpiece can be easily centered.

[0030] like Figure 4 As shown, springs 8 are fixedly installed on the inner walls of both ends of the middle part of the guide box 1, and the other end of the spring 8 is arranged on the side of the movable block 302 away from the fixed seat 4; a positioning block 9 is integrally formed on the side of the guide block 7 close to the movable block 302;

[0031] In this embodiment, the swinging amplitude of the movable block 302 away from the fixed seat 4 is limited by the positioning block 9. After the movable block 302 is blocked by the positioning block 9, the surface of the movable block 302 is at the same level as the guide block 7, which facilitates the rolled piece to enter the middle of the two guide blocks 7.

[0032] like Figure 1 and Figure 2 As shown, a guide rod 10 is fixedly installed at the middle top of the movable block 302, and guide grooves 11 are penetrated and opened at both ends of the right top of the guide box 1, and the guide rod 10 is slidably connected with the guide groove 11;

[0033] In this embodiment, when the movable block 302 swings back and forth, the guide rod 10 at the top of the middle portion of the movable block 302 will slide along the guide grooves 11 on both sides of the top of the guide box 1 for guidance.

[0034] Working principle: When in use, the workpiece is fed in from the opening 2 on the right side of the guide box 1. If the angle of the workpiece is too large during the feeding process, it will randomly touch the end of the movable block 302 on either side, and a fixed seat 4 is provided on the outer side of the end of the movable block 302, and the fixed seat 4 is welded and fixed to the guide box 1. The outer side of the end of the movable block 302 is blocked by the fixed seat 4 and will not be excessively stretched outward, so the workpiece is smoothly introduced by the movable block 302, thereby facilitating the rapid guidance of the workpiece; when the workpiece slides to the other end of the movable block 302, the end of the workpiece will squeeze the movable block 302, and the end of the movable block 302 close to the guide block 7 will be stretched outward after being compressed, and the stretched end of the movable block 302 drives the other end through the arc connecting rod 303 to push the rear section of the workpiece toward the middle, so that the workpiece can be conveniently centered.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model.
