[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution: a feeding mechanism for sheet metal shearing, including a support table 1 and a shearing assembly 2 provided at the rear end of the top surface of the support table 1. A plurality of strip-shaped grooves 1.1 extending transversely are arranged longitudinally on the top surface of the support table 1. A roller shaft 1.2 is rotatably sleeved between the two side walls of the inner cavity of the strip-shaped groove 1.1. Among them, the top end of the roller shaft 1.2 slightly protrudes from the top surface of the support table 1. A strip-shaped groove 1.3 is arranged transversely at the position on the top surface of the support table 1 in front of the shearing assembly 2.

[0024] The bearing seat 6 is fixed on the top surface of the support table 1 and close to the front side walls on both sides of the shearing assembly 2.

[0025] Both ends of the central axis of the feeding roller 5 are respectively rotatably sleeved on the bearing seats 6; the servo motor 7 is fixed on the outer wall of one of the bearing seats 6, and the servo motor 7 is used to drive the feeding roller 5 to rotate. Among them, the feeding roller 5 includes a roller body 5.1 whose two ends of the central axis are respectively rotatably sleeved on the bearing seats 6. A plurality of strip-shaped grooves 5.1.1 extending axially along its circumferential direction are arranged on the outer peripheral wall of the roller body 5.1. A strip-shaped block 5.2 is slidably and radially clamped in the strip-shaped groove 5.1.1. The outer end surface of the strip-shaped block 5.2 is an arc convex surface structure, and a spring 5.3 is connected between the strip-shaped block 5.2 and the inner bottom surface of the strip-shaped groove 5.1.1. So that when the strip-shaped block 5.2 rotates to the bottom, it can fit well on the top surface of the sheet material, so that the feeding roller 5 can feed sheet materials with different thicknesses.

[0026] The clamping members 3 are arranged in pairs, and each clamping member 3 includes a slider 3.1 slidably clamped on both sides of the middle part of the strip-shaped groove 1.3, a vertical roller 3.4 whose bottom end of the central axis is rotatably sleeved on the top surface of the slider 3.1, and a threaded sleeve 3.5 fixedly sleeved horizontally in the slider 3.1; among them, the top surface of the slider 3.1 is lower than the top surface of the support table 1.
