[0041] Wherein, the punching table 1 is configured as a U-shaped table structure, and the punching table 1 is located below the working output end of the metal punching machine;

[0042] The guide platform 2 is symmetrically arranged at the openings on both sides of the punching platform 1.

One side of the bottom end of the punching guide frame 13 is slidably connected to the side wall of the positioning block 7, and the positioning block 7 is located on the surface of the punching table 1 and is slidably connected;

[0045] In conjunction with the accompanying drawings Figure 1-6 As shown, when in use, the stamping table 1 is located below the precision mold at the output end of the stamping equipment. As the stamping guide frames 13 arranged on both sides of the stamping table 1 are docked with the output end of the stamping equipment, the take-off and landing positions of the output end of the stamping equipment are limited, which is convenient for regulating the position of the material belt. The guide tables 2 installed on both sides of the stamping table 1 are semicircular in structure, which is convenient for the material belt to be pushed into the inside of the stamping table 1 according to the conveying position requirements. The guide table 2 is arranged in an inclined surface, such as Figure 1-3 As shown, it is convenient to push the material strip into the inside of the stamping table 1. The auxiliary roller 3 arranged on the surface of the stamping table 1 is used to push the material strip to the other side. The hole on one side of the auxiliary roller 3 that penetrates the inside of the stamping table 1 is convenient for collecting the precision metal parts that have been stamped. As shown in 1-3, the telescopic column 4 symmetrically arranged on the upper end of the stamping table 1, as shown in Figure 4-5 As shown, the telescopic column 4 is an electrically driven two-stage sliding connection rod structure, such as Figure 1-6 As shown, the output end of the telescopic column 4 and the auxiliary roller 3 are arranged in parallel in a vertical direction, so that the output end of the telescopic column 4 pushes the corresponding correction component to correct the position of the steel strip entering the inside of the stamping table 1, so that the stamping guide frame 13 is stably installed and arranged during the stamping process as the output end of the stamping equipment descends;

[0046] The web guiding components include:

[0047] A flexible correction belt 5 is installed at the output end of the telescopic column 4, and the flexible correction belt 5 is symmetrically arranged inside the stamping table 1, one side of the flexible correction belt 5 is against the surface of the positioning block 7, and two flexible correction belts 5 are provided, and the flexible correction belts 5 are made of rubber material;

[0048] Contact switches 6, which are evenly arranged on the surface of the flexible correction belt 5;

[0049] The slide bar 8 is symmetrically arranged on both sides of the punching table 1, and one end of the slide bar 8 is located in the slide rail of the side wall of the punching table 1 to slide. A telescopic spring 9 is arranged on one side of the slide bar 8, and the telescopic spring 9 is installed inside the slide rail of the punching table 1, and the slide bar 8 is installed to align the midline of the guide frame 10;

[0050] The guide frame 10 is installed at the end of the slide rod 8. The guide frame 10 is set to a three-fold structure, and one end of the guide frame 10 connected to the silicone rod 11 is set to a convex structure. The middle section of the guide frame 10 is engaged with the shaft of the auxiliary rod 12, and the auxiliary rod 12 is a double-layer sleeve-shaped rotationally connected structure;

[0051] Silicone rods 11 are equidistantly arranged on the surface of the guide frame 10;

[0052] An auxiliary rod 12, the bottom end of which is engaged with the upper end of the guide frame 10;

[0053] In conjunction with the accompanying drawings Figure 1-6 As shown, the flexible correction belt 5 arranged at the output end of the telescopic column 4 is made of rubber material. The telescopic column 4 on the same side is based on the concave and convex position of the edge of the material belt. As the output end of the telescopic column 4 pushes the flexible correction belt 5 close to the edge of the material belt, the positioning block 7 located on the inner wall surface of the stamping table 1 moves with the displacement of the flexible correction belt 5, and is used to support the stable displacement of the flexible correction belt 5. The contact switch 6 is evenly arranged on the surface of the flexible correction belt 5. As the material belt contacts the contact switch 6 on the surface of the flexible correction belt 5, the contact switch 6 sends a signal to the control device of the telescopic column 4 to prevent the telescopic column 4 from excessively pushing the flexible correction belt 5 to squeeze the position of the material belt. The sliding rod 8 sliding inside the slide rail at both ends of the stamping table 1 is pushed by the elasticity of the telescopic spring 9. As the material belt passes between the two guide frames 10 on the same side, it contacts the silicone rod 11 on the surface of the guide frame 10. Among them, the two guide frames 10 are pushed by the telescopic spring 9 according to the width of the contacted material belt, so that the sliding rod 8 drives the guide frame 10 to move, which is convenient for correcting the position of the material belt. Since the guide frame 10 is a three-section structure, such as Figure 1-4 As shown, the auxiliary rod 12 located in the middle section of the guide frame 10 cooperates with the silicone rod 11 to guide the material strip. The outward-expanding structure is convenient for limiting the edge of the material strip from being excessively squeezed and deformed by the stamping equipment. The auxiliary rod 12 is a sleeve rod structure that is connected by concentric circles.

[0054] Working principle: When using the automatic deviation-correcting device for the material strip, the punching table 1 is placed at the bottom of the output end of the punching equipment. The guide tables 2 arranged at both ends of the punching table 1 are used to receive and push the steel material strip. When in use, the arc-shaped structure of the guide table 2 is convenient for receiving the steel material strip entering from different directions. The guide frame 10 installed above the guide table 2 is a silicone rod 11 for contacting and converging one side of the steel strip. The auxiliary rod 12 arranged at the upper end of the guide frame 10 cooperates with the silicone rod 11 to guide the steel strip. The guide frame 10 pushes the slide bar 8 along the side wall slide rail of the punching table 1 as the width of the steel strip pushes the slide bar 8, so that the opening between the two slide bars 8 cooperates with the width of the steel strip to squeeze the telescopic spring 9, which is convenient for the material strip to enter the inside of the punching table 1 and is located between the two groups of auxiliary rollers 3. The space between the two groups of auxiliary rollers 3 is convenient for the punching equipment and the punching The pressing table 1 cooperates with the stamping metal strip, and the flexible correction belt 5 arranged on both sides of the stamping table 1 is pushed by the electrically driven telescopic column 4, so that the contact switch 6 arranged on the surface of the flexible correction belt 5 is pushed close to the two sides of the strip, so that the strip is pushed to the center line position of the stamping table 1, and the deviation correction operation of the strip is realized. After the contact switches 6 on both sides of the strip are synchronously contacted, the contact switch 6 controls the telescopic column 4 to stop pushing the flexible correction belt 5 at the output end to excessively squeeze the strip. The positioning block 7 arranged on one side of the flexible correction belt 5 assists the flexible correction belt 5 to limit the support of the strip, and is located at the upper end of both sides of the stamping table 1 for sliding connection, wherein the stamping table 1 is directly connected to the output end of the stamping equipment through a connecting device, so as to keep the output end of the stamping equipment located inside the stamping table 1, thereby improving the quality of metal made by precise stamping of the strip and increasing the overall practicality.
