Description

Technical Field

[0001] This utility model relates to the field of punch press auxiliary equipment technology, and in particular to a universal roller feeding auxiliary tooling for punch presses. Background Technology

[0002] In punch press manufacturing, the processing of thin strip materials is particularly challenging due to the strip's inherent softness and fragility. During feeding, the strip is prone to sagging and bending, leading to defects such as poor material quality. This not only results in substandard product appearance but also causes significant waste of raw materials, severely impacting production costs, product quality, and efficiency.

[0003] There is an urgent need for a universal roller feeding auxiliary tooling specifically designed for the feed end of a punch press, capable of effectively supporting and assisting in the conveying of thin strips, to ensure the feeding of materials during punch press processing. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a universal roller feeding auxiliary tooling for punch presses.

[0005] This utility model proposes a universal roller feeding auxiliary fixture for punch presses, including a base plate installed on the worktable at the feed end of the punch press. The upper end of the base plate is connected to a positioning plate via a lifting mechanism. Side plates are vertically provided on both ends of the positioning plate. A conveying roller for conveying a material strip is installed between the two side plates located above the positioning plate. A pre-pressing plate for lightly pressing the material strip is provided in front of the conveying roller. An adjustable feeding roller assembly is installed at the inlet and outlet ends of the auxiliary fixture, respectively. Each adjustable feeding roller assembly includes two adjustable rollers. The distance between the two adjustable rollers matches the width of the material strip, and the height of the two adjustable rollers is adjustable to accommodate material strips of different thicknesses.

[0006] Preferably, the lifting mechanism includes:

[0007] There are four rotating cylinders, which are rotatably connected to the upper end of the base plate near the four corners.

[0008] The lead screw is threaded to the drum at the bottom and has a support plate fixed at the top. The side plate is fixed to the support plate.

[0009] Rotating the drum converts rotational motion into linear motion, causing the lead screw to move up and down, which in turn causes the positioning plate and the side plate to rise and fall.

[0010] Preferably, an outer side plate is fixed on the support plate located outside the side upright plate, and a horizontal plate is installed between the two outer side plates located above the conveyor roller. The pre-pressing plate is installed at the lower end of the horizontal plate by adjusting bolts, and the pressure of the pre-pressing plate on the material belt is adjusted by adjusting the tightness of the adjusting bolts.

[0011] Preferably, a silicone pad with a thickness of 3-5mm is adhered to the bottom of the pre-pressing plate.

[0012] Preferably, the axial direction of the adjustable roller is perpendicular to the axial direction of the conveying roller. Each adjustable roller is fixed with an adjusting rod. The lower end of the adjusting rod passes through the positioning plate and is screwed with a nut. By rotating the nut, the rotational motion is converted into linear motion, which drives the adjustable roller to move up and down, thereby adapting to material strips of different thicknesses.

[0013] Preferably, the outer layer of both the conveying roller and the adjustable roller is made of PU material.

[0014] In summary, this utility model has the following beneficial effects: The auxiliary tooling is installed on the worktable at the feed end of the punch press. Adjustable feeding roller assemblies are installed at both the inlet and outlet ends of the tooling, forming front and rear supports for the material strip, which can effectively prevent the material strip from sagging and bending during feeding. The pre-pressing plate pre-presses and flattens the material strip before feeding to avoid wrinkling, thereby significantly reducing the occurrence of folding defects; it reduces downtime and scrap rate caused by material strip sagging and bending and folding defects, and improves the continuity and stability of production; at the same time, it reduces raw material waste, effectively reduces production costs, and improves production efficiency.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] like Figure 1 As shown in this embodiment, a universal roller feeding auxiliary fixture for punch presses includes a base plate 1 installed on the worktable at the feed end of the punch press. The upper end of the base plate 1 is connected to a positioning plate 2 via a lifting mechanism. Side plates 3 are vertically provided on both sides of the positioning plate 2. A conveying roller 4 for conveying a material belt 5 is installed between the two side plates 3 located above the positioning plate 2. A pre-pressing plate 6 for lightly pressing the material belt 5 is provided in front of the conveying roller 4. An adjustable feeding roller assembly is installed at the inlet and outlet ends of the auxiliary fixture. Each adjustable feeding roller assembly includes two adjustable rollers 7. The distance between the two adjustable rollers 7 matches the width of the material belt 5. The material belt passes between the two adjustable rollers, and the height of the two adjustable rollers 7 is adjustable to accommodate material belts 5 of different thicknesses.

[0021] Thus, in this embodiment, the auxiliary tooling is installed on the worktable at the feed end of the punch press. Adjustable feeding roller assemblies are installed at both the inlet and outlet ends of the tooling, forming front and rear supports for the material strip 5. This effectively prevents the material strip 5 from sagging and bending during feeding. The pre-pressing plate 6 pre-presses and flattens the material strip 5 before feeding to avoid wrinkling, thereby significantly reducing the occurrence of folding defects. This reduces downtime and scrap rate caused by sagging and bending of the material strip 5 and folding defects, improving the continuity and stability of production. At the same time, it reduces raw material waste, effectively reduces production costs, and improves production efficiency.

[0022] Furthermore, the lifting mechanism includes:

[0023] There are four rotating cylinders 8, which are rotatably connected to the upper end of the base plate 1 near the four corners.

[0024] The number of lead screws 9 matches that of the rotating drum 8. The lower part is threaded to the rotating drum 8, and the upper end is fixed with a support plate 10. The side plate 3 is fixed on the support plate 10.

[0025] Rotating the drum 8 converts the rotary motion into linear motion, driving the lead screw to move up and down, which in turn drives the positioning plate 2 and the side plate 3 to rise and fall. Fine adjustments can be made manually according to the height of the machine tool mold to ensure precise alignment between the strip 5 and the punch press inlet, preventing the strip 5 from sagging or bending due to height mismatch.

[0026] Furthermore, an outer side plate 11 is fixed to the support plate 10 located outside the side upright plate 3, and a horizontal plate 12 is installed between the two outer side plates 11 located above the conveyor roller 4. The pre-pressing plate 6 is installed at the lower end of the horizontal plate 12 by adjusting bolts 13, and the pressure of the pre-pressing plate 6 on the material belt 5 is adjusted by adjusting the tightness of the adjusting bolts 13. The material belt 5 is pre-pressed and flattened before feeding to prevent the material belt 5 from wrinkling or folding.

[0027] The bottom of the pre-press plate 6 is covered with a silicone pad with a thickness of 3-5mm. The silicone pad has a smooth surface and can be gently pressed onto the material strip 5.

[0028] In this embodiment, the axial direction of the adjustable roller 7 is perpendicular to the axial direction of the conveying roller 4. Each adjustable roller 7 is fixed with an adjusting rod 14. The lower end of the adjusting rod 14 passes through the positioning plate 2 and is screwed with a nut 15. By rotating the nut 15, the rotational motion is converted into linear motion, which drives the adjustable roller 7 to move up and down, thereby adapting to material belts 5 of different thicknesses. This forms front and rear supports for the material belt 5, which can effectively prevent the material belt 5 from sagging and bending during the feeding process.

[0029] It should be noted that the outer layer of both the conveyor roller 4 and the adjustable roller 7 is made of PU material [Polyurethane (PU)]. PU has good elasticity and wear resistance, and will not scratch the surface of the conveyor belt 5 during support and conveying, thus ensuring the product's appearance quality and reducing raw material waste caused by poor appearance.

[0030] In summary, the auxiliary tooling structure in this embodiment is compact, occupies a small area, can be easily installed at the feeding end of various punch presses, has a wide range of applications, does not occupy too much production space, and improves the space utilization rate of the workshop.
