Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical manufacturing, in particular to a stamping die for flat steel of a shelf. Background Art
[0002] With the increasing use of forklifts, backstops, as essential components of forklifts, are gaining increasing attention in their production. Key components of backstops are made of flat steel, which is primarily profiled using hydraulic presses, which rely on profiling dies. Current profiling dies present numerous challenges in the flat steel profiling process. Firstly, workers rely on measuring dimensions and drawing centerlines on the dies for alignment. This method not only struggles with precision but also lacks position limits and positioning devices, leading to inaccurate profiling and negatively impacting product quality. Secondly, for longer flat steel, two workers are required: one holding the raw material while the other performs the profiling. This is labor-intensive and time-consuming, increasing labor costs and reducing production efficiency. Furthermore, the lack of effective support devices causes the flat steel to shake during operation, further compromising profiling quality. Finally, vulnerable areas of existing profiling dies cannot be disassembled. Damage renders the entire die useless, significantly increasing operating costs. Furthermore, this non-detachable design limits mold maintenance and upgrades, hindering the company's long-term development. Utility Model Content

[0020] A stamping die for forming flat steel for a shelf backstop comprises a lower plate 8, characterized by a lower die 10 and an upper die 4. The lower die 10 is fixedly connected to the lower plate 8. A heightening plate 9 is fixedly connected above the upper die 4. An upper plate 1 is fixedly connected above the heightening plate 9. The upper plate is connected to a stamping component, namely a hydraulic press. The lower die 10 is located directly below the upper die 4. Both the lower die 10 and the upper die 4 have center lines cut into their sides. Support plates 6 are fixedly connected to both sides of the lower die 10, each of which has a rectangular tube 11 fixedly connected to its top. Two lower die connecting plates 7 are located on either side of the lower die 10. A limit block 5 is fixedly connected to one side of each lower die connecting plate 7. The lower die 10 has a groove located between the two lower die connecting plates 7. The upper die 4 and the heightening plate 9 are fixedly connected by screws and cylindrical pins, while the heightening plate 9 is fixedly connected to the upper plate 1 by screws and cylindrical pins.
[0021] The lower die connecting plate 7 is removable, allowing for easy replacement if damaged. The surface of the lower die connecting plate 7, near the groove, is machined with a 2° bevel for easier demolding. By replacing rectangular tubes 11 of varying lengths and heightened plates 9 of varying thicknesses, flat steel of varying sizes can be used. The grooves of the lower die 10 and the profiles of the upper die 4 are customized to the desired product profile.
[0022] When the utility model is in use, the upper plate of the pressing die in the figure: 1 is installed on the upper end of the hydraulic press, and the lower plate 8 is fixed on the work surface of the hydraulic press. Then the worker measures and marks the flat steel required for pressing the shelf, and then places the flat steel on the lower die 10, and aligns the marked position with the center line cut by the upper die 4, and one side of the flat steel is in contact with the limit block 5. The rectangular tubes 11 on both sides of the lower die 10 can support the flat steel. The hydraulic press switch is stepped on, and the upper die 4 moves downward. When the upper die 4 contacts the limit block 5, the hydraulic press switch is released, and the upper die 4 moves back, and finally the product is taken out.
