Referring to fig. 2, 5, and 6, specifically, the mounting plate 120 is provided with a mounting hole 121, the clamping assembly 220 is mounted on a portion of an inner wall of the mounting hole 121, and the clamping assembly 220 and the portion of the inner wall of the mounting hole 121 can together form a feeding channel. Specifically, the driving assembly 210 includes a clamping driver 211 and a feeding push block 212, and the clamping driver 211 can drive the feeding push block 212 to move in the vertical direction. The clamping assembly 220 comprises a fixed clamping block 221 and a movable clamping block 222, the fixed clamping block 221 is fixedly installed on the installation plate 120 and is located on one side of the material strip 20, the movable clamping block 222 is opposite to the feeding push block 212, and the feeding push block 212 can push the movable clamping block 222 to horizontally slide relative to the installation plate 120. In this way, under the pushing action of the feeding pushing block 212, the movable clamping block 222 and the fixed clamping block 221 cooperate with a part of the inner wall of the mounting hole 121 to clamp the bar 20.

Specifically, one side of the feeding push block 212 facing the movable clamping block 222 is a first inclined surface 212a, one side of the movable clamping block 222 facing the feeding push block 212 is a second inclined surface 222a, and the first inclined surface 212a and the second inclined surface 222a are inclined in the same direction along the vertical direction. In this way, the movement of the feeding push block 212 in the vertical direction is converted into the sliding movement of the movable clamping block 222 in the horizontal direction. Specifically, in the vertical upward direction, the first inclined surface 212a is gradually inclined toward the movable clamping block 222 side so that the feeding pushing block 212 has a frustum-shaped structure with a large upper part and a small lower part, so that when the feeding pushing block 212 moves downward in the vertical direction, the first inclined surface 212a abuts against the second inclined surface 222a and forces the movable clamping block 222 to move in the direction away from the feeding pushing block 212 to clamp the bar 20. When the feeding push block 212 moves upwards in the vertical direction, the first inclined surface 212a is far away from the second inclined surface 222a, and the movable clamping block 222 no longer has clamping force on the material strip 20. Specifically, the two clamping assemblies 220 are respectively located at two sides of the feeding push block 212, and two opposite sides of the feeding push block 212 are respectively provided with a first inclined surface 212a, so as to be respectively corresponding to the two clamping assemblies 220, that is, when the clamping driver 211 drives the feeding push block 212 to move along the vertical direction, the feeding push block 212 can simultaneously act on the two movable clamping blocks 222 to move, so as to clamp the two bars 20.

Specifically, the clamping assembly 220 further includes two mounting blocks 223, the two mounting blocks 223 are respectively disposed on two sides of the movable clamping block 222 and are respectively connected to the mounting plate 120, so as to limit the movable clamping block 222 in the first stepped groove 121a along the vertical direction. Further, the movable clamping block 222 includes a main body portion 222b and two ear portions 222c respectively connected to two sides of the main body portion 222b, two mounting blocks 223 are in one-to-one correspondence with the two ear portions 222c, and a part of the mounting blocks 223 are pressed against the ear portions 222c, so that the ear portions 222c are limited between the mounting blocks 223 and the bottom wall of the first stepped groove 121a, and only the sliding of the movable clamping block 222 along the length direction of the first stepped groove 121a is retained. Specifically, one side of the main body portion 222b facing the bottom wall of the first stepped groove 121a is hollowed out to reduce the weight of the movable clamping block 222, and meanwhile, the contact area between the movable clamping block 222 and the bottom wall of the first stepped groove 121a is also reduced, so that the friction force applied to the movable clamping block 222 during sliding is reduced, and the feeding push block 212 can exert a timely and effective pushing force on the movable clamping block 222. In addition, when the clamping mechanism 200 does not clamp the material strip 20, the movable clamping block 222 with small weight can reduce the resistance received by the material strip 20 during feeding, and prevent the material strip 20 from being bent or broken due to overlarge resistance.

Specifically, a second stepped groove 121b is formed in the side wall of the mounting hole 121, the fixed clamping block 221 is just mounted in the second stepped groove 121b, the fixed clamping block 221 is opposite to one side surface of the bar 20, a cushion block 224 is arranged on the side surface of the fixed clamping block 221 facing the bar 20, and the cushion block 224 abuts against the side surface of the bar 20, so that when the bar 20 is fixed, the surface of the bar 20 is prevented from being damaged and the surface quality of a product is prevented from being affected. Specifically, two cushion blocks 224 are arranged on the fixed clamping block 221, and the two cushion blocks 224 are arranged in the vertical direction to keep the bar 20 stable while pressing the side surface of the bar 20.

Specifically, the inner wall of the mounting hole 121, which forms a feeding channel, includes a first abutting surface 121c and a second abutting surface 121 d.

The second abutting surface 121d is opposite to the movable clamping block 222, so as to abut against the other two opposite side surfaces of the bar 20. Furthermore, the positions of the material strip 20 opposite to the movable clamping block 222 and the second abutting surface 121d are both in a semi-cylindrical structure, the second abutting surface 121d is a plane and inclined toward one side of the first abutting surface 121c, the position of the movable clamping block 222 abutting against the material strip 20 is a plane and inclined toward one side of the first abutting surface 121c, and the movable clamping block 222 is matched with the second abutting surface 121d, so that the trend of oppositely pressing the material strip 20 is realized, and the trend of pressing the material strip 20 against the second abutting surface 121d is also realized. Moreover, the movable clamping block 222 and the second abutting surface 121d are in line-line contact with the bar 20, so that the contact area can be reduced, and the resistance applied to the feeding of the bar 20 is reduced. It should be noted that, in other embodiments, the fixed clamping block 221 may be directly omitted, only the movable clamping block 222 and a part of the inner wall of the mounting hole 121 jointly enclose the feeding channel, and the movable clamping block 222 cooperates with the inner wall of the mounting hole 121 to jointly clamp the bar 20.
