Description

Technical Field

[0001] This application belongs to the field of stamping technology, specifically relating to a continuous stamping die. Background Technology

[0002] Continuous stamping dies, with their multi-station collaborative operation, enable the continuous forming and processing of metal materials, occupying a pivotal position in modern manufacturing and widely used in mass production of automotive parts, electronic components, precision instruments, and other fields. Their efficient and stable production capacity relies on precise coordination between each station, and the spacing function, as one of the core elements ensuring this coordination, directly relates to the processing accuracy of the product and the continuity of production.

[0003] The purpose of the spacing function is to ensure that the material strip is fed precisely and consistently over a continuous feeding process, allowing the material to accurately reach the processing area of ​​each station, thereby ensuring that each process is completed at the preset position. Currently, the commonly used spacing method is purely mechanical rigid spacing. However, this method relies on a mechanical structure of fixed stops or gear meshing. After long-term stamping, the wear of the contact parts will directly lead to the accumulation of spacing errors. For example, a 0.1mm wear on the edge of the stop will synchronously increase the feeding deviation, resulting in low yield in material strip stamping production and the generation of batches of scrap. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides a continuous stamping die. Through the design of the distance fixing component, the distance fixing component has the characteristics of dynamic linkage and flexible adjustment. The elastic part of the distance fixing component can absorb the impact force, effectively reduce wear, reduce the probability of rigid damage, ensure the quality of use of the distance fixing component, improve its durability, and thus ensure the high-quality operation of the stamping process, greatly improve the production yield, and reduce the generation of scrap.

[0005] The technical effects to be achieved in this application are realized through the following aspects: This application provides a progressive stamping die, comprising: The upper die mechanism includes a fixed component and a stamping component, one end of which is connected to the fixed component. The lower mold mechanism is disposed opposite to the upper mold mechanism. The lower mold mechanism includes a distance fixing component, which includes a support part, a sliding part, and an elastic component. The elastic component is connected to the sliding part, and the sliding part is movably connected to one side of the support part. The other side of the support portion is provided with a through hole, which is opposite to the stamping part, and the size of the through hole is not smaller than the size of the stamping part; The sliding part is used to abut against the bridge position in the material belt so that the material belt can be transported at a fixed distance; the stamping part is used to stamp the bridge position in the material belt that the sliding part abuts against.

[0006] In some implementations, the support portion is further provided with a limiting groove and a guide groove, the guide groove being inclinedly disposed on the side of the limiting groove near the through hole.

[0007] In some implementations, the sliding part includes a movable body and a guide block. The guide block is inclinedly disposed on one side of the movable body and is embedded in the guide groove. The movable body is embedded in the guide groove, and the elastic component is connected to the lower end of the movable body.

[0008] In some implementations, the upper end of the guide block is provided with an abutment surface that abuts against the bridge position in the material strip, and the abutment surface is in contact with the side of the bridge position in the material strip.

[0009] In some implementations, the tilt angle α of the guide block in the horizontal section is any value between 35° and 50°.

[0010] In some implementations, the elastic component includes a stop screw, a spring, and a pin, with one end of the spring connected to the stop screw, the other end of the spring connected to the pin, and the end of the pin away from the spring fixedly connected to the sliding part. When the spring is in a free state, the sliding part protrudes from the support part and is used to abut against the bridge position in the material strip; When the spring is in a compressed state, the sliding part is embedded in the support part, and the stamping part stamps the bridge position in the strip.

[0011] In some implementations, the lower die mechanism further includes a lower die component, and the distance fixing component is embedded in the lower die component; the lower die component has a channel corresponding to the through hole, the channel is connected to the through hole, and both the channel and the through hole are used for the discharge of the bridge position after stamping.

[0012] In some implementations, the upper die mechanism further includes a movable component and an elastic component, one end of the elastic component is connected to the fixed component, the other end of the elastic component is connected to the movable component, and the stamping part passes through the movable component; When the elastic element is in a free state, the stamped part is located inside the movable part; When the elastic element is in a compressed state, the stamped part protrudes from the movable part.

[0013] In some implementations, the movable component includes an upper ejector plate and a stop plate connected together, one end of the stop plate being connected to the elastic element, and the upper ejector plate being disposed opposite to the lower mold mechanism.

[0014] In some implementations, the fixing component includes an upper mold base, an upper pad, and an upper clamping plate connected sequentially from top to bottom, with the upper clamping plate positioned opposite to the movable component.

[0015] In summary, this application has at least the following advantages: The continuous stamping die provided in this application, through the setting of a spacer assembly, uses a sliding part to abut against the bridge position in the strip, thereby controlling the strip to enter the stamping preparation stage. Subsequently, the stamping part in the upper die mechanism stamps towards the sliding part, causing the sliding part to embed into the support part. The stamping part stamps the bridge position in the strip. After the stamping is completed, the upper die mechanism rises, and the elastic component resets and ejects the sliding part, allowing the sliding part to intercept the bridge position in the next strip, thus achieving continuous stamping operation. Because the spacer assembly has the characteristics of dynamic linkage and flexible adjustment, it can absorb impact force through the elastic component, effectively reducing wear, lowering the probability of rigid damage, ensuring the quality of use of the spacer assembly, improving its durability, and thus ensuring the high-quality operation of the stamping process, greatly improving production yield and reducing the generation of scrap.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0026] Example 1: Please see the appendix Figure 1 This application discloses a continuous stamping die, comprising an upper die mechanism 1 and a lower die mechanism 2. The upper die mechanism 1 includes a fixed component 11 and a stamping component 12, one end of which is connected to the fixed component 11. The lower die mechanism 2 is disposed opposite to the upper die mechanism 1 and includes a distance-fixing component 21. The distance-fixing component 21 includes a support portion 211, a sliding portion 212, and an elastic component 213. The elastic component 213 is connected to the sliding portion 212, and the sliding portion 212 is movably connected to one side of the support portion 211. The other side of the support portion 211 is provided with a through hole 214, which is disposed opposite to the stamping component 12, and the size of the through hole 214 is not smaller than the size of the stamping component 12. The sliding portion 212 is used to abut against the bridge position 31 in the strip 3 to enable the strip 3 to achieve distance-fixed transport. The stamping component 12 is used to stamp the bridge position 31 in the strip 3 abutted by the sliding portion 212.

[0027] In this embodiment of the continuous stamping die, the upper die mechanism 1 and the lower die mechanism 2 are initially separated, and the strip 3 is conveyed between the upper die mechanism 1 and the lower die mechanism 2. At this time, the sliding part 212 protrudes from the support part 211 because the elastic member 213 is in a free state. When the bridge position 31 in the strip 3 moves to abut against the sliding part 212, the strip 3 stops conveying, and the upper die mechanism 1 presses down towards the lower die mechanism 2, so that the sliding part 212 is pressed into the support part 211. The stamping part 12 punches the bridge position 31 in the strip 3 to the through hole 214. After the punching is completed, the upper die mechanism 1 rises, and the sliding part 212 returns to its initial position by the compressive force of the elastic member 213, which facilitates intercepting the bridge position 31 in the next strip 3. The above steps are repeated to achieve the continuity of stamping. It can be understood that the specific operation of each component in the overall stamping process can be realized by combining existing technologies such as PLC control programs and sensors.

[0028] Through the above technical solution, the spacer assembly 21, with its dynamic linkage and flexible adjustment characteristics, can absorb the impact force during the stamping process through the elastic component 213. This effectively reduces wear, lowers the probability of rigid damage, ensures the quality of use of the spacer assembly 21, improves its durability, and thus ensures the stability of the stamping process, greatly improving production yield and reducing the generation of scrap. On the other hand, due to the durability of the spacer assembly 21, the frequency of maintenance due to wear can be reduced, effectively improving the overall stamping efficiency.

[0029] In addition, in this structure, the through hole 214 and the stamping part 12 work together. During the stamping process, the stamping part 12 punches the bridge position 31 in the strip 3 into the through hole 214. This setting can simultaneously punch zinc powder and iron filings into the through hole 214 during the production process, thereby greatly reducing the presence of zinc powder and iron filings during the conveying of the strip 3, improving the cleanliness of the continuous stamping process, and greatly improving the appearance of the product.

[0030] Example 2: The difference between this embodiment and Embodiment 1 is that, please refer to... Figures 2-4 In this embodiment, the support portion 211 is also provided with a limiting groove 2111 and a guide groove 2112. The guide groove 2112 is inclinedly disposed on the side of the limiting groove 2111 near the through hole 214. The sliding portion 212 is provided with a movable body 2121 and a guide block 2122. The guide block 2122 is inclinedly disposed on one side of the movable body 2121. The guide block 2122 is embedded in the guide groove 2112. The movable body 2121 is embedded in the guide groove 2112. The elastic member 213 is connected to the lower end of the movable body 2121.

[0031] In this embodiment, the distance-fixing component 21 employs a limiting groove 2111 of the support part 211 and a movable body 2121 that fit together, and a guide block 2122 and a guide groove 2112 that fit together, ensuring that the sliding part 212 moves in a specific direction. During the stamping preparation stage, the sliding part 212 can intercept the bridge position 31 in the strip 3. During the stamping process, the movable body 2121 can enter the limiting groove 2111 without affecting the stamping action of the stamping part 12 on the bridge position 31 of the strip 3. Through this setting, the sliding part 212 can move up and down stably and accurately, and the functions of each component are independent, making it highly practical and ensuring a strong overall stamping cycle.

[0032] In some embodiments, the upper end of the guide block 2122 is provided with an abutment surface 2123 that abuts against the bridge position 31 in the strip 3, and the abutment surface 2123 is in close contact with the side of the bridge position 31 in the strip 3. Through this setting, the lateral movement of the strip 3 can be directly constrained. The abutment surface 2123 can increase the contact area with the bridge position 31 in the strip 3, thereby achieving the stability of the bridge position 31 in the strip 3, ensuring that the stamping part 12 accurately punches the strip 3, and guaranteeing the punching quality.

[0033] In some embodiments, see Figure 4 The tilt angle α of the guide block 2122 in the horizontal section is any value between 35° and 50°. With this setting, when the elastic member 213 is in a free state, the abutment surface 2123 of the guide block 2122 is above the through hole 214. During the downward punching process of the upper die mechanism 1, due to the setting of the tilt angle α, the guide block 2122 moves downward and simultaneously moves away from the through hole 214, which can ensure the smooth progress of the punching and guarantee the punching quality. Moreover, this setting can reduce the error of the punching position of the bridge position 31 caused by the movement of the guide block 2122, thereby improving the accuracy of the punching.

[0034] In some embodiments, see Figure 5 The elastic component 213 includes a fixing screw 2131, a spring 2132, and a ejector pin 2133. One end of the spring 2132 is connected to the fixing screw 2131, and the other end of the spring 2132 is connected to the ejector pin 2133. The end of the ejector pin 2133 away from the spring 2132 is fixedly connected to the sliding part 212. When the spring 2132 is in a free state, the sliding part 212 protrudes from the support part 211 and is used to abut against the bridge position 31 in the material strip 3. When the spring 2132 is in a compressed state, the sliding part 212 is embedded in the support part 211, and the stamping part 12 stamps the bridge position 31 in the material strip 3.

[0035] Specifically, when the spring 2132 is in a free state, the ejector pin 2133 pushes the sliding part 212 out of the support part 211, thus intercepting the bridge position 31 in the strip 3; when the spring 2132 is in a compressed state, the sliding part 212 is pressed and embedded in the support part 211, realizing the fixed-distance stamping operation of the strip 3. This overall structure is simple and practical, ensuring the stable movement of the sliding part 212, thereby ensuring the smoothness of the stamping process. Furthermore, the fixing screw 2131 serves as a fixed end, effectively ensuring the overall stability of the elastic component 213.

[0036] In some embodiments, see Figure 6 The lower die mechanism 2 also includes a lower die component 22, and a spacing component 21 is embedded in the lower die component 22. The lower die component 22 has a channel 221 corresponding to the through hole 214. The channel 221 is connected to the through hole 214, and both the channel 221 and the through hole 214 are used for the discharge of the bridge position 31 after stamping. By setting the channel 221, the bridge position 31 in the stamped strip 3 enters the channel 221 from the through hole 214 and is directly discharged without manual processing, which effectively improves the discharge efficiency. At the same time, the waste generated during the stamping process can also be discharged. The overall stamping process has strong cycle time, and the stamping process is cleaner.

[0037] Example 3: The difference between this embodiment and Embodiment 2 is that, please refer to... Figure 7 The upper mold mechanism 1 in this embodiment also includes a movable part 13 and an elastic member 14. One end of the elastic member 14 is connected to the fixed part 11, and the other end of the elastic member 14 is connected to the movable part 13. The stamping member 12 passes through the movable part 13. When the elastic member 14 is in a free state, the stamping member 12 is disposed in the movable part 13. When the elastic member 14 is in a compressed state, the stamping member 12 protrudes from the movable part 13.

[0038] In this embodiment, the upper die mechanism 1, through the cooperation of the movable part 13 and the elastic element 14, can achieve a dynamic adaptive stamping function. Specifically, the compression state of the elastic element 14 directly determines the extension length of the stamped part 12. When the die moves downward, the movable part 13 is compressed, causing the elastic element 14 to compress, and the stamped part 12 extends to perform the stamping action; when the die moves upward, the elastic element 14 resets, causing the movable part 13 to return to its initial position, and the stamped part 12 retracts. This design can achieve automatic extension and retraction of the stamped part 12 without an additional driving device, and is especially suitable for complex processes that require multi-stage stamping or step-by-step forming, making it highly practical. Furthermore, the elastic element 14 in this structure absorbs the impact load during stamping, reducing rigid impact. In addition, the structure is simple in design and easy to maintain.

[0039] In some embodiments, the movable component 13 includes an upper ejector plate 131 and a stop plate 132 connected to each other. One end of the stop plate 132 is connected to the elastic member 14, and the upper ejector plate 131 is disposed opposite to the lower mold mechanism 2.

[0040] Specifically, the upper ejector plate 131 is directly opposite to the lower die mechanism 2. Before the stamping operation begins, the upper ejector plate 131 contacts the strip 3 before the punch, and under the pre-tightening force of the elastic element 14, it presses the strip 3 between the upper and lower dies. This pre-tightening action can prevent the strip 3 from shifting or wrinkling due to force during the stamping process, ensuring the accuracy of the punching and forming position. In addition, the upper ejector plate 131 and the stop plate 132 are rigidly connected to form an integral moving part 13, which can maintain stable perpendicularity and coaxiality during movement.

[0041] In some embodiments, the fixed component 11 includes an upper die base 111, an upper pad 112, and an upper clamping plate 113 connected sequentially from top to bottom, with the upper clamping plate 113 disposed opposite to the movable component 13. This arrangement allows the upper die base 111, upper pad 112, and upper clamping plate 113 to be precisely fitted together using pin positioning and bolt fastening to form a rigid whole, improving the overall stability of the die and ensuring stable stamping execution.
