Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to an adjustable mechanical stamping die. Background Art

[0002] In modern manufacturing, mechanical stamping dies are widely used in the forming process of various metal sheets. Adjustable mechanical stamping dies are favored because they can adapt to workpieces of different sizes and shapes, but existing adjustable mechanical stamping dies still have some significant shortcomings in practical applications, especially in controlling the thickness of stamping workpieces and accurately stamping and positioning plates of different sizes.

[0003] Existing adjustable mechanical stamping dies have obvious deficiencies in controlling the thickness of stamped workpieces. Many traditional stamping dies are relatively simple in design and lack precise adjustment mechanisms to ensure uniform thickness of the workpiece after stamping. In this case, even if the same sheet is stamped multiple times, it is difficult to ensure that the thickness after each stamping is exactly the same. This not only affects the quality consistency of the product, but may also lead to an increase in scrap rate and increase production costs. In addition, in applications where strict control of thickness tolerances is required, such as automotive parts manufacturing, electronic component packaging, etc., the instability of this thickness control will directly affect the performance and safety of the final product.

[0004] Accurately positioning the stamping plates of different sizes is also a major problem with existing adjustable mechanical stamping dies. Due to the limitations of the die structure, when it is necessary to replace plates of different sizes, it is often necessary to manually adjust the position of the die or reset the stamping parameters. This process is not only time-consuming and labor-intensive, but also prone to human errors, resulting in stamping position deviations. Especially for products with high precision requirements, even a slight position deviation may result in unqualified products. In addition, frequent manual adjustments will increase the workload of operators and reduce production efficiency.

[0005] Existing adjustable mechanical stamping dies are even more incapable of dealing with complex shapes and multi-step stamping processes. For example, in some complex stamping operations, multiple stamping operations of different depths and shapes may be required on the same sheet. Existing dies can usually only be achieved by replacing different die parts, which not only increases the preparation time of the die, but may also cause poor fit between the dies, further affecting the stamping effect. Therefore, the development of a multifunctional die that can complete multiple stamping tasks in one clamping and can accurately control the position of each stamping point has become an urgent problem to be solved.

[0006] The existing adjustable mechanical stamping dies also need to be improved in terms of automation. Although some advanced stamping equipment already has a certain degree of automation, in actual production, a lot of manual intervention is still required for die adjustment and calibration. This not only reduces the overall efficiency of the production line, but also increases labor costs. The ideal solution should be to develop a highly automated stamping die system that can automatically detect the sheet size through sensors and control systems, and automatically adjust the die position and stamping parameters according to preset parameters, so as to achieve efficient and accurate stamping operations.

[0007] Therefore, how to provide an adjustable mechanical stamping die is a problem that those skilled in the art need to solve urgently. Summary of the invention

The correction slide plate 6.15 drives the correction cylinder 6.16 and the correction clamp 6.1 to move. The correction clamp 6.1 is affected by the size of the stamping material and presses against the correction clamp 6.1. The displacement of the correction clamp 6.1 is blocked. The elliptical block 6.14 swings on the top of the slide frame 6.11. The rotation of the elliptical block 6.14 slides along the bottom of the correction slide plate 6.15. The correction clamp 6.1 can adapt to stamping plates of different sizes and align the stamping positions of stamping plates of different sizes.

[0049] The present invention inserts an inner hexagonal wrench into the second hexagonal groove 6.20 and rotates the inner hexagonal wrench. The rotation of the inner hexagonal wrench drives the rotation of the torsion rod 6.18. The rotation of the torsion rod 6.18 is screwed in or out of the sliding column 6.22, thereby controlling the length of the correction clamp 6.1 extending out of the correction tube 6.16, thereby controlling the alignment of the groove of the correction clamp 6.1 with the two sides of the stamping plate. The torsion rod 6.18 is rotated, and the convex ring 6.19 of the torsion rod 6.18 is used to press the correction clamp 6.1 to completely enter the correction tube 6.16, thereby avoiding affecting the smoothness of the length direction of the stamping plate.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
