DETAILED DESCRIPTION

[0021] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0022] like Figure 1 - Figure 4 As shown, a sheet metal punching and feeding mechanism includes a feeding mechanism, a limiting mechanism, an adjusting mechanism and a conveying platform 2 arranged on a punching and cutting machine body 1, wherein the feeding mechanism is arranged on the top of the punching and cutting machine body 1, the conveying platform 2 is arranged inside the punching and cutting machine body 1, and the conveying platform 2 slides on the feeding mechanism, and the adjusting mechanism is arranged inside the conveying platform 2.

[0023] Furthermore, the feeding mechanism includes a three-phase asynchronous motor 16, which is installed on the top of one side of the punching machine body 1. The output shaft end of the three-phase asynchronous motor 16 is fixedly connected to a second screw 17. Two guide rods 18 are fixedly connected to the top of the punching machine body 1 near the outside of the second screw 17. The two guide rods 18 are symmetrically arranged. The conveying platform 2 is connected to the outer wall of the second screw 17 through threads, and the two guide rods 18 pass through one side of the same conveying platform 2, so as to facilitate starting the three-phase asynchronous motor 16 to drive the second screw 17 to rotate, thereby facilitating the movement of the position of the conveying platform 2.

[0024] Furthermore, a placement hole 3 is opened on one side of the conveying platform 2, so that the sheet metal can be placed and pass through the conveying platform 2, which is convenient for the subsequent conveying of the sheet metal by the conveying platform 2.

[0025] Furthermore, the limiting mechanism includes an electric push rod 4, which is installed on the top of the conveying platform 2. A pressure plate 5 is fixedly connected to the output end of the conveying platform 2. A plurality of movable holes 6 are opened at the top of the pressure plate 5. The plurality of movable holes 6 are arranged in a rectangular array. First screw rods 7 are threadedly connected to both sides of the conveying platform 2. The outer ends of the two first screw rods 7 respectively penetrate the two sides of the conveying platform 2 and extend to the inside of the placement hole 3. One end of the two first screw rods 7 is connected to a connecting plate 8 through a bearing seat. Two limit plates 9 are fixedly connected to the bottom end of the connecting plate 8. The two limit plates 9 are symmetrically arranged. The outer wall of the limit plate 9 is located inside the movable hole 6 and is adapted to the inside of the movable hole 6, so that when the pressure plate 5 moves up and down, it does not affect the restriction of the two groups of limit plates 9 on the position of the sheet metal.

[0026] Furthermore, the adjustment mechanism includes a threaded hole 10, which is opened at the bottom end of the placement hole 3. A stud 12 is connected to the threaded hole 10. A first mounting hole 11 communicating with the threaded hole 10 is opened on one side of the conveying platform 2. A pull plate 13 is fixedly connected to the outer wall of the stud 12 near the first mounting hole 11. A second mounting hole 14 is opened at the top of the stud 12. A plurality of auxiliary rollers 15 are rotatably connected to the second mounting hole 14. The plurality of auxiliary rollers 15 are linearly arranged and equidistantly arranged, so that the plurality of auxiliary rollers 15 can support the sheet metal and move the position of the sheet metal.

[0027] Furthermore, the horizontal planes at the tops of the several auxiliary rollers 15 are flush with the inner bottom surface of the placement hole 3, and the movement angle of the pull plate 13 from one side of the inner wall of the first mounting hole 11 to the other side is ninety degrees, which makes it easy for the stud 12 to drive the several auxiliary rollers 15 to rotate from parallel to one side of the conveyor platform 2 to perpendicular to one side of the conveyor platform 2, thereby facilitating the subsequent lateral movement of the sheet metal.

[0028] Working principle: First, pull the pull plate 13 clockwise 90 degrees, so that the pull plate 13 drives the stud 12 to rotate upward. At this time, the pull plate 13 rotates upward inside the first mounting hole 11. When the pull plate 13 moves from one side of the inner wall of the first mounting hole 11 to the other side, the stud 12 drives the auxiliary roller 15 to rotate to be perpendicular to one side of the conveyor 2, and the sheet metal is placed and passed through the placement hole 3, so that one end of the sheet metal is located inside the punching machine body 1, and the bottom end of the sheet metal contacts the top of several auxiliary rollers 15, which is convenient for the staff to push the sheet metal horizontally to adjust the position, avoiding a large contact area between the sheet metal and the conveyor 2, and a large friction, which requires the staff to lift the sheet metal before adjustment;

[0029] Secondly, rotate the two first screw rods 7 so that the two first screw rods 7 drive the two connecting plates 8 to move to the two sides of the sheet metal respectively. At this time, the connecting plate 8 drives the limiting plate 9 to move inside the moving hole 6 until the two sets of limiting plates 9 contact and limit the two sides of the sheet metal respectively. Then reset the pull plate 13 so that the pull plate 13 drives the stud 12 to rotate downward. Since the sheet metal is restricted by the two sets of limiting plates 9, the stud 12 is screwed into the threaded hole 10 without moving the position of the sheet metal. At this time, the bottom surface of the sheet metal contacts the bottom end of the placement hole 3 and the top of several auxiliary rollers 15, and the electric push rod 4 is started. At this time, the electric push rod 4 drives the pressure The plate 5 presses the surface of the sheet metal, and then the three-phase asynchronous motor 16 is started, so that the three-phase asynchronous motor 16 drives the second screw 17 to rotate, and the second screw 17 drives the conveying platform 2 to move, so that the conveying platform 2 gradually pushes the sheet metal as a whole into the inside of the punching machine body 1 for punching. When one side of the conveying platform 2 is close to the punching device on the punching machine body 1, the extrusion device on the punching machine body 1 is used to facilitate the pressing and supporting of the sheet metal, and the electric push rod 4 and the three-phase asynchronous motor 16 are reset again to a position away from the punching device, so as to complete the feeding work of the sheet metal.
