Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a feeding centering die for a material strip. Background Art

[0002] At the start of production, the initial feed is positioned widthwise by guide plates on either side of the strip. Due to the gap between these plates and the strip, the strip can sometimes align with one guide plate and be off-center. Some complex products require multiple stamping steps, each requiring dimensional requirements from the strip's features to the strip's edges, making dimensions unstable and difficult to guarantee. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a feeding centering die for a material strip, which can correct the position of the material strip before being punched, and ensure that the position of the punched guide hole is more accurate.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a feeding centering mold for a material strip, including: a lower mold base, a lower mold base is provided on the lower mold base, a unloading upper mold base is arranged on the side of the lower mold base away from the lower mold base, a unloading guide block is provided on the unloading upper mold base, the unloading guide block has guide slopes extending toward both sides of the material strip, a floating block is slidably connected in the lower mold base, and a supporting platform for supporting the material strip extends toward the unloading introduction block from the floating block, when the unloading introduction block moves toward the supporting platform, the material strip is guided to the center of the supporting platform by the guide slope, and a floating component for supporting the floating position of the floating block is provided on the lower mold base.

[0005] Preferably, the floating assembly includes a floating through hole, a floating spring, a push rod and a plug screw opened in the lower die base. The floating spring is arranged in the floating through hole. The plug screw is arranged at one end of the lower die base away from the unloading upper die base, for blocking one end of the floating through hole and abutting against one end of the floating spring. The push rod is arranged at the other end of the floating through hole and one end of the push rod abuts against the other end of the floating spring, and the other end of the push rod abuts against the floating block.

[0006] Preferably, a lower die pad is provided between the lower die base and the lower die plate, and a limiting through hole is provided on the lower die pad to cooperate with one end of the ejector rod facing the floating material block.

[0007] Preferably, an elastic pressing assembly is provided between the unloading upper die base and the unloading inlet block, and the elastic pressing assembly includes a spring groove, a pressing spring and a limit plate provided on the unloading inlet block. One end of the pressing spring is against the unloading upper die base, and the other end is against the unloading inlet block through the spring groove. The limit plate is fixedly connected to the unloading upper die base to limit the range of movement of the unloading inlet block on the unloading upper die base, and the unloading inlet block and the limit plate are slidably matched.

[0008] Preferably, a correction groove matching the width of the material strip is formed between the guide slopes at both ends of the unloading inlet block facing the supporting platform.

[0009] The beneficial effects of the utility model are:

[0010] The position of the material strip is supported by the supporting platform. When the unloading guide block approaches the supporting platform, the guide slopes on both sides are used to force the material strip to be gradually straightened and centered on the supporting platform, thereby ensuring the accuracy and consistency of the material strip position, and thus making the position of the guide holes punched out by the material strip when being stamped more accurate. Even if the gap between the guide plate and the material strip is appropriately increased to increase the smoothness of feeding, it will not affect the accuracy of the material strip position, and can also improve the utilization rate of uncut materials and reduce the frequency of mold repair.

[0023] Physical quantities in formulas, unless otherwise specified, should be understood as basic quantities of the International System of Units (SI) basic units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation or integration.

[0024] Example:

[0025] refer to Figure 1-Figure 3 , a feeding centering mold for a material strip, comprising: a lower mold base 1, a lower mold plate 2 is provided on the lower mold base 1, a discharge upper mold base 3 is arranged on the side of the lower mold base 2 away from the lower mold base 1, a discharge introduction block 4 is movably connected to the discharge upper mold base 3, the discharge introduction block 4 has guide slopes 5 extending toward both sides of the material strip 20, a floating block 6 is slidably connected to the lower mold base 2, and the floating block 6 extends toward the discharge introduction block 4 to have a bearing platform 7 for carrying the material strip 20, when the discharge introduction block 4 moves toward the bearing platform 7, the material strip 20 is guided to the center on the bearing platform 7 through the guide slope 5, and a floating component for supporting the floating position of the floating block 6 is provided on the lower mold base 1;

[0026] The material strip 20 is loaded from the material guide plate 21 and is conveyed to the supporting platform 7. At this time, the material strip 20 on the supporting platform 7 may not be centered. At this time, the unloading upper mold base 3 moves toward the supporting platform 7 driven by an external device. The maximum distance between the guide slopes 5 on both sides of the unloading introduction block 4 is greater than the width of the material strip 20. Therefore, even if the material strip 20 is not centered and deviates to one side, it will not affect the unloading introduction block 4 to guide the material strip 20 to the center on the supporting platform 7.

[0027] refer to Figure 2 and Figure 3In order to provide a certain position compensation when the unloading inlet block 4 presses the material belt 20 to the center, and to avoid the technical problems of excessive pressing and damaging the material belt 20 or not pressing into place and not fully centering the material belt 20, the floating assembly includes a floating through hole, a floating spring 9, a push rod 10 and a plug screw 11 opened in the lower die base 1. The floating spring 9 is arranged in the floating through hole, and the plug screw 11 is threadedly connected to the end of the lower die base 1 away from the unloading upper die base 3, which is used to block one end of the floating through hole so that one end of the floating spring 9 is against the plug screw 11, and the push rod 10 is arranged at the other end of the floating through hole so that one end of the push rod 10 is against the end of the floating spring 9 away from the plug screw 11, and then the floating spring 9 supports the position of the push rod 10, and then the other end of the push rod 10 is against the floating block 6, thereby providing a certain position compensation for the floating block 6 and the supporting platform 7.

[0028] refer to Figure 2 and Figure 3 In order to limit the maximum distance that the ejector pin 10 can move toward the floating block 6, and to limit the ejector pin 10 in the lower die base 1 to avoid it from escaping from the lower die base 1, a lower die pad 12 is provided between the lower die base 1 and the lower template 2. The lower die pad 12 can be bolted to the lower die base 1. A limiting through hole is provided on the lower die pad 12 to match the end of the ejector pin 10 facing the floating block 6. The diameter of the limiting through hole only allows the head of the ejector pin 10 with a smaller diameter to pass through, while the tail of the ejector pin 10 cannot pass through the limiting through hole because its size is larger than the limiting through hole. Therefore, the ejector pin 10 directly passes through the lower die pad 12 to support the position of the floating block 6 and provide position compensation for the floating block 6.

[0029] refer to Figure 2 and Figure 3 In order to provide a certain position compensation for the unloading guide block 4 and to make the unloading guide block 4 separate from the centered material belt 20 after the material belt 20 is centered, an elastic pressing component is provided between the unloading upper die base 3 and the unloading guide block 4. The elastic pressing component includes a spring groove, a pressing spring 15 and a limit plate 16 opened on the unloading guide block 4. One end of the pressing spring 15 is against the unloading upper die base 3, and the other end is against the unloading guide block 4 through the spring groove, thereby forcing the unloading guide block 4 to move toward the supporting platform 7. The limit plate 16 is bolted to the unloading upper die base 3 to limit the range of movement of the unloading guide block 4 on the unloading upper die base 3. The unloading guide block 4 slides with the limit plate 16 to limit the maximum moving distance of the unloading guide block 4 toward the floating block 6. The elastic force of the pressing spring 15 is greater than the elastic force of the floating spring 9.

[0030] refer to Figure 2 and Figure 3In order to further ensure the stability and accuracy of the unloading introduction block 4 in guiding the material strip 20 to the center, a correction groove 17 that matches the width of the material strip 20 is formed between the guiding inclined surfaces 5 at both ends of the unloading introduction block 4 facing the supporting platform 7. The correction groove 17 is equal to the width of the material strip 20 or slightly larger than the width of the material strip 20, so that when the material strip 20 is guided to the center, the material strip 20 is just in the correction groove 17, thereby further ensuring the stability and accuracy of the position of the material strip 20 when it is guided to the center.

[0031] Working process: The material strip 20 passes through the guide plate 21 and reaches the carrier platform 7. Driven by external equipment, the unloading upper mold base 3 and the unloading guide block 4 move toward the material strip 20 on the carrier platform 7. First, the guiding slope 5 of the unloading guide block 4 contacts the edge of the material strip 20 and gradually guides the material strip 20 to the center on the carrier platform 7 using the guiding slope 5. At this time, the unloading guide block 4 completely presses the carrier platform 7, completing the mold closing;

[0032] After the stamping is completed, when the external equipment drives the unloading upper die base 3 to open the mold, because the elastic force of the pressing spring 15 is greater than the elastic force of the floating spring 9, the unloading guide block 4 will first bounce open under the action of the pressing spring 15, and the floating block 6 will then bounce open under the action of the floating spring 9 and the push rod 10 until the mold is fully opened.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
