[0023] like Figure 1-2As shown, the utility model provides a stable card sleeve stamping forming structure device, including an upper die assembly, a lower die assembly, an outer guide assembly, an inner guide assembly and a stripping mechanism.

When the card sleeve stamping and forming structure device of the utility model is in operation, the upper die assembly moves downward, so that the outer guide pin 14 enters the outer guide sleeve to complete the initial positioning, and then the inner guide pin 15 enters the inner guide sleeve to complete the precise positioning, so that the central axis of the stretch forming punch 10 and the stretch forming punch 10 coincide, thereby ensuring the concentricity of the product; the upper die assembly is pressed down into place, and the stretching die 18 cooperates with the stretch forming punch 10 to perform precise stamping and forming; after completion, the upper die assembly moves upward, and the stripping mechanism pushes the formed part out to complete the stamping operation. The card sleeve stamping and forming structure device of the utility model ensures the concentricity of the product and improves the qualified rate of the product through the guiding and positioning functions of the outer guide assembly and the inner guide assembly; at the same time, the material can be automatically unloaded through the stripping mechanism, thereby improving the production efficiency.

[0024] like Figure 1 As shown, the upper die assembly includes an upper die seat 1, an upper pad 2 and an upper clamping plate 3, which are positioned in sequence by an upper die positioning pin 19, so that the central axes of the three coincide, ensuring the overlapping position accuracy of the three plates, thereby ensuring the concentricity of the product; further, the upper die locking bolt 16 passes through the die seat 1 and the upper pad 2 in sequence and is threadedly connected to the upper clamping plate 3, so that the three are connected and fixed as a whole. Among them, a stretching die 18 is fixedly embedded at the center of the bottom of the upper clamping plate 3, which is used for stamping and forming the outer side of the ferrule, and its central axis coincides with the upper clamping plate 3, and the bottom is flush with the bottom of the upper clamping plate 3.

[0025] The lower die assembly includes a lower clamping plate 5, a lower pad 6 and a lower die seat 7, which are positioned in sequence by a lower die positioning pin 8 so that the central axes of the three coincide with each other, thereby ensuring the overlapping position accuracy of the three plates and thus ensuring the concentricity of the product; further, the lower die locking bolt passes through the lower die seat 7 and the lower pad 6 in sequence and is threadedly connected to the lower clamping plate 5, thereby connecting and fixing the three together.

The diameter of the outer guide column 14 is adapted to the inner diameter of the outer guide sleeve, and it is symmetrically arranged at the top diagonal positions of the lower die seat 7. The upper die assembly moves downward, so that the outer guide column 14 is inserted into the outer guide sleeve, and the upper die seat 1 is linearly displaced in the vertical direction through the cooperation and limitation of the two, thereby completing the initial positioning of the upper die assembly and the lower die assembly in the vertical direction.

[0027] The inner guide assembly includes an inner guide sleeve and an inner guide column 15; the bottom of the inner guide sleeve is flush with the bottom of the upper clamp plate 3, and the top is flush with the top of the upper pad 2. There are four inner guide sleeves, which are symmetrically located at the four corners of the upper clamp plate 3. The diameter of the inner guide column 15 is adapted to the inner diameter of the inner guide sleeve. The bottom of the inner guide column 15 is fixed on the lower pad 6, and the top of the inner guide column passes through the lower clamp plate 5 and is aligned with the corresponding inner guide sleeve. The upper mold assembly moves downward, so that the four inner guide columns 15 are inserted into the inner guide sleeve. Through the cooperation and limitation of the two, the stretching forming punch 10 and the stretching die 18 are linearly displaced in the vertical direction, thereby completing the precise positioning of the stretching forming punch 10 and the stretching die 18 in the vertical direction. Since the central axes of the two coincide, the concentricity of the product during stamping and stretching can be effectively guaranteed, and the qualified rate of the product can be significantly improved.

[0028] The stripping mechanism includes a stripping plate 4 and an upper die stripping ejector rod 17, wherein the stripping plate 4 is located at the top of the lower clamping plate 5, and a through hole is opened in the center thereof for passing the stretch forming punch 10; further, a positioning circular groove is provided at the center of the top of the stripping plate 4, which is used to limit the placement of the ferrule blank, so that the blank can be placed stably and its central axis coincides with the central axis of the stretch forming punch 10, thereby improving the positioning accuracy and ensuring the concentricity of the product. The bottom of the upper die stripping ejector rod 17 is located through the stretching die 18, and the top is fixed above the top of the upper die seat 1. As the upper die assembly moves upward, it presses down on the molded part and pushes the molded part out of the stretching die 1; the central axis of the upper die stripping ejector rod 17 coincides with the central axis of the stretch forming punch 10 to ensure the concentricity of the stamped product.

[0029] Furthermore, the stripper plate 4 is pushed by the spring assembly to move linearly upward, thereby ejecting the formed part from the stretch forming punch 10; the spring assembly includes a limiting slide, a strong spring 11 and an equal height push rod 12; the limiting slide is provided with four groups, two of which are symmetrically arranged in the lower mold assembly and located below the four corners of the stripper plate 4; the equal height push rod 12 is a T-shaped rod, including a sliding part arranged in the limiting slide and a push part fixedly arranged on the top of the sliding part, and the diameter of the sliding part is equal to the inner diameter of the limiting slide. At the same time, the equal-height push rod 12 is linearly displaced in the vertical direction along the limit slide. The diameter of the push part is the same as the diameter of the through hole opened on the lower clamping plate 5. The upper end of the push part passes through the through hole and is fixedly connected to the bottom of the stripping plate 4; the outer diameter of the strong spring 11 is the same as the inner diameter of the slide, and its top is connected to the bottom of the equal-height push rod 12, and the bottom is connected to the bottom of the limit slide; further, the bottom of the limit slide is provided with a set screw 9, which is threadedly connected to the bottom of the lower die seat 7, which can facilitate the installation and later maintenance of the spring assembly. When stripping, the four groups of strong springs 11 push the equal-height push rod 12 to move linearly upward respectively, so that the stripping plate 4 drives the molded part to move upward until the maximum push stroke of the equal-height push rod 12 is reached, and the molded part is flush with the top of the stretch forming punch 10, and the molded part is blown out of the equipment through an external air gun to complete the unloading work.

[0035] S500: The upper die assembly moves upward, and the four sets of strong springs 11 push the equal-height push rods 12 to move upward linearly, thereby causing the stripping plate 4 to drive the formed part to move upward until the formed part is flush with the top of the stretch forming punch 10

[0036] S600: the upper die stripping ejector 17 presses down the molded part as the upper die assembly moves upward, pushing the molded part out of the drawing die 1, and completing the stripping of the molded part;

[0037] S700: The external air gun blows the molded parts out of the equipment to complete the unloading work.

[0038] The ferrule stamping and forming structure device of the utility model, through the guiding and positioning effect of the outer guide component and the inner guide component, makes the central axes of the stretching die 18 and the stretching forming punch 10 coincide during stamping, and a positioning circular groove is provided at the center of the top of the stripper plate 4, so that the blank can be placed stably and its central axis coincides with the central axis of the stretching forming punch 10, thereby improving the positioning accuracy, ensuring the concentricity of the product, and improving the product qualification rate.
