Description

Technical Field

[0001] This application relates to the field of strip processing technology, and in particular to a stamping device. Background Technology

[0002] In the stamping process of complex metal parts, multiple stamping stations are usually integrated together to stamp the strip material multiple times to form the metal part. However, integrating all the stamping stations together requires a very large stamping equipment that occupies a lot of space. Moreover, such large stamping equipment is scarce, and conventional workshops and factories cannot meet the height and load-bearing requirements. Manufacturing precision cannot be guaranteed, resulting in a huge waste of resources and low equipment utilization. Very few manufacturers would invest in such large and underutilized equipment. However, without such equipment, manufacturers cannot undertake the development and manufacturing of the aforementioned metal parts.

[0003] Considering the combination of resources and project competitive advantages, existing technologies propose integrating multiple stamping devices together to perform the stamping process and stamp the strip. However, in order to ensure synchronous stamping by multiple stamping devices, it is generally necessary to connect the power shafts of adjacent stamping devices using couplings. The preparation work before the stamping process is complicated, and the couplings between the devices need to be disassembled after the stamping process, which reduces the user experience. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a stamping device, comprising:

[0005] At least two stamping devices are arranged sequentially at intervals to stamp the same strip of material.

[0006] At least one safety detection device is provided between adjacent stamping devices. The safety detection device is used to obtain the difference in conveying speed of the material strip between two adjacent stamping devices.

[0007] The safety detection device includes at least one distance sensor, which is used to detect the distance between the distance sensor and the material strip to obtain the difference in conveying speed of the material strip between two adjacent stamping devices.

[0008] The safety detection device includes a first ranging sensor and a second ranging sensor. The first ranging sensor and the second ranging sensor are arranged at a distance from each other along the direction of gravity. The detection area of ​​the first ranging sensor is set towards the second ranging sensor, and the detection area of ​​the second ranging sensor is set towards the first ranging sensor.

[0009] The material strip is threaded between the first distance sensor and the second distance sensor. The first distance sensor is used to detect the distance between the first distance sensor and the material strip, and the second distance sensor is used to detect the distance between the second distance sensor and the material strip. The first distance sensor and the second distance sensor work together to obtain the difference in conveying speed of the material strip between two adjacent stamping devices.

[0010] The strip between two adjacent stamping devices is bent, and the lowest point of the bent strip is at a height less than the height of the worktable surface of the stamping device relative to the placement surface.

[0011] Wherein, the height of the first ranging sensor relative to the placement surface of the stamping equipment is less than or equal to the height of the worktable surface of the stamping equipment relative to the placement surface.

[0012] The height difference between the first ranging sensor and the worktable surface of the stamping device relative to the placement surface is within the range of 0 to 30 cm.

[0013] The height difference between the second ranging sensor and the placement surface of the stamping equipment is within the range of 15 to 30 cm.

[0014] The distance between two adjacent stamping devices is in the range of 1 to 1.5 m.

[0015] The height difference between the worktable surfaces of two adjacent stamping devices and the placement surface of the stamping equipment is within the range of -10 to 10 cm.

[0016] The conveying speed of the stamping device on the strip is positively correlated with the stamping speed of the stamping device on the strip.

[0017] The beneficial effects of this application are as follows: Unlike existing technologies, the stamping equipment of this application includes at least two stamping devices and at least one safety detection device. At least two stamping devices are arranged sequentially at intervals for stamping the same strip material; and at least one safety detection device is installed between adjacent stamping devices to obtain the difference in the conveying speed of the strip material between the two adjacent stamping devices. By setting a safety detection device in the stamping equipment to detect the difference in the conveying speed of the strip material between the two adjacent stamping devices, the stamping equipment can adjust its own conveying speed based on the difference to ensure that the conveying speed of the strip material between the stamping devices is equal. This eliminates the need for an additional coupling to connect the power shaft of the stamping devices, simplifying the installation steps. Furthermore, it can promptly stop the stamping devices when the conveying speeds of the two adjacent stamping devices are inconsistent, or when there is a shortage of material, improving the safety of the stamping equipment and enhancing the user experience.

[0023] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0024] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0025] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone.

Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the stamping equipment of this application. The stamping equipment A provided in this embodiment includes at least two stamping devices 1 and at least one safety detection device 2.

[0028] In the stamping equipment A, the stamping devices 1 are arranged sequentially at intervals to stamp the same strip 3. Different stamping devices 1 cooperate with each other to stamp strips 3 with a longer length, and different stamping devices 1 can perform different stamping processes on the strip 3 to form the required metal parts.

[0029] Each stamping device 1 has a strip conveying mechanism for transporting the strip 3, and the conveying speed of the strip 3 by each stamping device 1 is controlled by that specific stamping device 1. Different stamping devices 1 control the conveying of the strip 3 independently. Therefore, during the process of multiple stamping devices 1 cooperating to stamp the same strip 3, it is necessary to ensure that the conveying speed of the strip 3 by the multiple stamping devices 1 is consistent to guarantee the stability of the stamping equipment A's operation.

[0030] Therefore, in the stamping device A of this application, at least one safety detection device 2 is provided between adjacent stamping devices 1. The safety detection device 2 is used to obtain the difference in conveying speed of the material belt 3 between two adjacent stamping devices 1. Then, when the conveying speed of two adjacent stamping devices 1 is inconsistent, or when there is a shortage of material, the safety detection device 2 can issue an alarm to remind the user to control the stamping device 1 to stop. Alternatively, the safety detection device 2 can directly transmit a signal to the stamping device 1, and the stamping device 1 can stop in time according to the signal to avoid damage to the stamping device 1 and improve the safety of the stamping equipment A.

[0031] For example, with Figure 1 Taking the stamping equipment A shown as an example, a safety detection device 2 is installed between adjacent stamping devices 1. If the safety detection device 2 detects that the conveying speed of the left stamping device 1 to the material strip 3 is faster than that of the right stamping device 1 to the material strip 3, the left stamping device 1 can be adjusted to reduce its conveying speed to the material strip 3; and / or, the right stamping device 1 can be adjusted to increase its conveying speed to the material strip 3, so as to ensure that the conveying speeds of the two adjacent stamping devices 1 to the material strip 3 are equal.

[0032] It is understandable that the adjustment of the stamping device 1 can be done manually by the user or by the stamping device 1 itself to adapt and improve the automation level of the stamping equipment A.

[0033] Specifically, after the safety detection device 2 detects the difference in the conveying speed of the material belt 3 between two adjacent stamping devices 1, the safety detection device 2 can transmit the difference to the processors of the two adjacent stamping devices 1 respectively. Then, based on the difference detected by the safety detection device 2, the processors of the two stamping devices 1 control the stamping devices 1 to adjust the conveying speed of the material belt 3 to ensure that the conveying speed of the material belt 3 between the two adjacent stamping devices 1 is equal, that is, to ensure the synchronous operation of the two adjacent stamping devices 1.

[0034] In one embodiment, two or more safety detection devices 2 may be provided between two adjacent stamping devices 1. For example, when the distance between two adjacent stamping devices 1 is large, multiple safety detection devices 2 can be provided to improve detection accuracy. This can be configured according to user needs, and this application does not impose any restrictions on this.

[0035] This embodiment of the application installs a safety detection device 2 between two adjacent stamping devices 1. The safety detection device 2 detects the difference in conveying speed of the material strip 3 between the two adjacent stamping devices 1, ensuring that the conveying speeds of the material strip 3 are equal. This improves the operational stability and efficiency of the stamping equipment A, and increases the stamping efficiency of the material strip 3. The safety detection device 2 can also control the stamping devices 1 to stop promptly when the conveying speeds of the two adjacent stamping devices 1 are inconsistent, or when there is a shortage or lack of material, preventing damage to the stamping devices 1 and improving the safety of the stamping equipment A.

[0036] By installing a safety detection device 2 between adjacent stamping units 1, it is no longer necessary to use a coupling to connect the punching shafts of two adjacent stamping units, as is done in the prior art, to ensure synchronous operation of the two adjacent stamping units. The prior art requires modifications to the power shafts of the stamping units to allow them to connect with the power shafts of other stamping units, resulting in complex preparatory work.

[0037] This application ensures the synchronous operation of two adjacent stamping devices 1 by setting up a safety detection device 2. The stamping device 1 can be operated independently without any preparation work for stamping the same strip 3 with other stamping devices 1. This simplifies the installation difficulty of stamping equipment A, and stamping equipment A can perform stamping work on longer strips 3, improving the user's experience of using stamping equipment A.

[0038] Optionally, the safety detection device 2 may include at least one distance sensor, which is used to detect the distance between the distance sensor and the material belt 3 to obtain the difference in conveying speed of the material belt 3 between two adjacent stamping devices 1. In one embodiment, the distance sensor may be a sensor capable of distance measurement, such as an optical fiber sensor.

[0039] Specifically, the strip 3 between two adjacent stamping devices 1 can be threaded onto the safety detection device 2. The distance sensor can be located above or below the portion of the strip 3 that passes through the safety detection device 2, thereby enabling the distance sensor to detect the distance between the distance sensor and the strip 3.

[0040] As mentioned above, the conveying speed of the material strip 3 by different stamping devices 1 is controlled by the stamping device 1 itself. That is, the conveying speed of the material strip 3 by different stamping devices 1 may not be equal.

[0041] When the conveying speed of the material belt 3 is equal between the two adjacent stamping devices 1, the distance between the distance sensor and the material belt 3 remains unchanged. At this time, the distance sensor can determine that the conveying speed of the material belt 3 is equal between the two adjacent stamping devices 1.

[0042] When the conveying speed of the material strip 3 is not equal between the two adjacent stamping devices 1, the material strip 3 may accumulate or become taut between the two adjacent stamping devices 1, which will change the distance between the distance sensor and the material strip 3. At this time, the distance sensor can determine that the conveying speed of the material strip 3 is not equal between the two adjacent stamping devices 1.

[0043] Here, two adjacent stamping devices 1 are defined as the first stamping device and the second stamping device. The first stamping device is located in front of the safety detection device 2 along the setting direction of the multiple stamping devices 1, and the second stamping device is located behind the safety detection device 2. After the first stamping device stamps the material strip 3, it will then transfer the stamped material strip 3 to the second stamping device for stamping. After the second stamping device stamps the material strip 3, it will then transfer the material strip 3 to another stamping device 1 adjacent to the second stamping device.

[0044] Taking the distance sensor located above the material strip 3 as an example, the distance sensor can be preset with a preset distance range. When the conveying speed of the material strip 3 by the two adjacent stamping devices 1 is equal (that is, the conveying speed of the first stamping device to convey the material strip 3 to the second stamping device is equal to the conveying speed of the second stamping device to convey the material strip 3 to another stamping device 1 adjacent to the second stamping device), the distance between the material strip 3 and the distance sensor remains basically unchanged and is within the preset distance range.

[0045] When the distance between the material belt 3 and the distance sensor is less than the minimum value in the preset distance range, that is, the conveying speed of the material belt 3 by the first stamping device and the second stamping device is different, and the conveying speed of the material belt 3 by the second stamping device is greater than that by the first stamping device, the material belt 3 between the first stamping device and the second stamping device is taut, and the distance between the material belt 3 and the distance sensor becomes smaller, the distance sensor can transmit the detected difference result to the first stamping device and the second stamping device, so that the first stamping device increases the conveying speed of the material belt 3, and / or the second stamping device decreases the conveying speed of the material belt 3, so as to ensure that the conveying speed of the material belt 3 by the first stamping device and the second stamping device is equal, ensuring the synchronous operation of the two adjacent stamping devices 1, ensuring that the two adjacent stamping devices 1 convey the material belt 3 at the same speed, maintaining the distance between the material belt 3 and the distance sensor, ensuring the consistency of operation of the first stamping device and the second stamping device, and ensuring the stability of the operation of the stamping equipment A.

[0046] When the distance between the distance sensor and the material strip 3 is detected by the distance sensor as being greater than the maximum value in the preset distance range, that is, the conveying speed of the material strip 3 by the first stamping device and the second stamping device is different, and the conveying speed of the material strip 3 by the first stamping device is greater than that by the second stamping device, the second stamping device fails to receive the material strip 3 conveyed by the first stamping device in time. The material strip 3 accumulates between the first stamping device and the second stamping device, and the curvature of the material strip 3 increases. Therefore, the distance between the material strip 3 and the distance sensor increases. At this time, the distance sensor can transmit the detected difference to the first stamping device and the second stamping device so that the first stamping device reduces the conveying speed of the material strip 3, and / or the second stamping device increases the conveying speed of the material strip 3, so as to ensure that the conveying speed of the material strip 3 by the first stamping device and the second stamping device is equal, and to ensure the synchronous operation of the two adjacent stamping devices 1.

[0047] In another embodiment, the distance sensor can also be located below the material belt 3. When the distance sensor is located below the material belt 3, the detection principle for the difference in conveying speed of the material belt 3 between two adjacent stamping devices 1 is the same as the detection principle when the distance sensor is located above the material belt 3, and will not be described in detail here.

[0048] In other embodiments, a preset conveying speed can be set in the stamping device 1 of the stamping equipment A. This preset conveying speed is the user's ideal conveying speed of each stamping device 1 to the material strip 3 in the stamping equipment A. After receiving the difference result transmitted by the safety detection device 2, the stamping device 1 can adjust its own conveying speed based on the difference result, the current conveying speed of the material strip 3, and the preset conveying speed. For example, if the ranging sensor detects that the conveying speed of the first stamping device to the material strip 3 is greater than that of the second stamping device, then the current conveying speed of the first stamping device should be greater than the preset conveying speed. In this case, the first stamping device can appropriately reduce its conveying speed so that its conveying speed to the material strip 3 is equal to the preset conveying speed. Conversely, if the current conveying speed of the second stamping device is less than the preset conveying speed, then the second stamping device can appropriately increase its conveying speed so that its conveying speed to the material strip 3 is equal to the preset conveying speed.

[0049] By setting a preset conveying speed, the direction for adjusting the conveying speed of different stamping devices 1 is provided, avoiding the situation where the conveying speed of the stamping device 1 is infinitely reduced or infinitely increased, which would affect the stamping efficiency of the stamping equipment A on the material strip 3.

[0050] Furthermore, if the distance sensor cannot detect strip 3, it can be assumed that there is a shortage of material in stamping equipment A, and the machine should be stopped immediately to replenish strip 3. Specifically, if there is a shortage of strip 3 in stamping equipment A, it may be because when the first stamping device transfers strip 3 to the second stamping device, the first stamping device lacks strip 3 to pull it, causing one end of strip 3 to detach and fall out of the safety detection device 2, thus preventing the distance sensor from detecting its presence. Therefore, if the distance sensor cannot detect strip 3, it can be assumed that there is a shortage of material in stamping equipment A, prompting the user to stop the machine and replenish the material. This improves the safety of stamping equipment A's operation and prevents stamping device 1 from operating without strip 3, which could damage the die core.

[0051] In summary, the safety detection device 2 in stamping equipment A can issue an alarm to remind the user to stop the stamping device 1 when the conveying speed of two adjacent stamping devices 1 is inconsistent, or when there is a shortage of material. Alternatively, the safety detection device 2 can directly transmit a signal to the stamping device 1, and the stamping device 1 can stop in time according to the signal to avoid damage to the stamping device 1 and improve the safety of stamping equipment A.

[0052] Optional, please refer to the following: Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of an embodiment of the safety detection device of this application. The safety detection device 2 includes a first ranging sensor 21 and a second ranging sensor 22. The first ranging sensor 21 and the second ranging sensor 22 are arranged at a distance from each other along the direction of gravity. The detection area of ​​the first ranging sensor 21 faces the second ranging sensor 22, and the detection area of ​​the second ranging sensor 22 faces the first ranging sensor 21. The material belt 3 passes between the first ranging sensor 21 and the second ranging sensor 22. That is, the first ranging sensor 21 can be located above the material belt 3, and the second ranging sensor 22 can be located below the material belt 3.

[0053] The first distance sensor 21 is used to detect the distance between the first distance sensor 21 and the material belt 3, and the second distance sensor 22 is used to detect the distance between the second distance sensor 22 and the material belt 3. The first distance sensor 21 and the second distance sensor 22 work together to obtain the difference in conveying speed of the material belt 3 between two adjacent stamping devices 1.

[0054] Specifically, two adjacent stamping devices 1 may include a first stamping device and a second stamping device. The first stamping device is located in front of the first distance sensor 21 and the second distance sensor 22, and the second stamping device is located behind the first distance sensor 21 and the second distance sensor 22. As mentioned above, when the conveying speed of the material strip 3 by the first stamping device is greater than that by the second stamping device, the material strip 3 accumulates between the two stamping devices 1, and the curvature of the material strip 3 increases. At this time, the first distance sensor 21 can detect that the distance between the material strip 3 and the first distance sensor 21 has increased, while the second distance sensor 22 can detect that the distance between the material strip 3 and the second distance sensor 22 has decreased. Therefore, through the cooperation of the first distance sensor 21 and the second distance sensor 22, the difference in the conveying speed of the material strip 3 by the two adjacent stamping devices 1 can be obtained, determining that the conveying speed of the material strip 3 by the first stamping device is greater than that by the second stamping device.

[0055] When the conveying speed of the second stamping device to the material strip 3 is greater than that of the first stamping device to the material strip 3, the material strip 3 between the two stamping devices 1 is taut. At this time, the first distance sensor 21 can detect that the distance between the material strip 3 and the first distance sensor 21 has decreased, while the second distance sensor 22 can detect that the distance between the second distance sensor 22 and the material strip 3 has increased. Thus, by cooperating with the first distance sensor 21 and the second distance sensor 22, it can be determined that the conveying speed of the second stamping device to the material strip 3 is greater than that of the first stamping device 1 to the material strip 3, and the difference in conveying speed of the material strip 3 between the two adjacent stamping devices 1 can be obtained.

[0056] Compared to the embodiment where the safety detection device 2 includes only one ranging sensor, the safety detection device 2 includes a first ranging sensor 21 and a second ranging sensor 22 disposed on opposite sides of the conveyor belt 3. The detection areas of the two ranging sensors are opposite to each other, which can work together to improve the detection accuracy of the conveyor belt 3. However, since the detection area of ​​the ranging sensor is limited, as mentioned above, the distance between the conveyor belt 3 and the ranging sensor may be greater than the maximum value of the preset distance range. In this case, the conveyor belt 3 may exceed the detection area of ​​the ranging sensor, which will affect the detection efficiency of the ranging sensor for the conveyor belt 3.

[0057] In this embodiment, by setting a first ranging sensor 21 and a second ranging sensor 22 on opposite sides of the material belt 3, when the distance between the material belt 3 and the first ranging sensor 21 increases, the distance between the material belt 3 and the second ranging sensor 22 decreases. That is, the material belt 3 will definitely fall within the detection range of the second ranging sensor 22. Conversely, when the distance between the material belt 3 and the second ranging sensor 22 increases, the distance between the material belt 3 and the first ranging sensor 21 decreases, and the material belt 3 will definitely fall within the detection range of the first ranging sensor 21. Through the cooperation of the first ranging sensor 21 and the second ranging sensor 22, the detection efficiency of the safety detection device 2 can be improved.

[0058] Alternatively, please continue reading Figure 1 The strip 3 between two adjacent stamping devices 1 is curved, and the lowest point of the curved strip 3 is less than the height of the worktable 11 of the stamping device 1 relative to the placement surface of the stamping device A.

[0059] The surface on which the stamping equipment A is placed can be the ground. As mentioned above, when the conveying speed of the material strip 3 by the first stamping device is less than that by the second stamping device, the material strip 3 between the two stamping devices 1 will be taut and straight. Therefore, if the material strip 3 between the two adjacent stamping devices 1 is not provided with a certain tolerance length, it is very likely to be straightened and then broken when the material strip 3 is taut. In this embodiment, the material strip 3 is set to be curved between the two stamping devices 1, and the lowest point of the curved material strip 3 is less than the height of the worktable 11 of the stamping device 1. This provides some tolerance for the material strip 3 between the two stamping devices 1, ensuring the integrity of the material strip 3 during the tautness process and improving the safety of the operation of the stamping equipment A.

[0060] Optionally, the height of the first ranging sensor 21 relative to the placement surface of the stamping device A is less than or equal to the height of the worktable surface 11 of the stamping device 1 relative to the placement surface.

[0061] Specifically, as mentioned above, the first distance sensor 21 is positioned above the strip 3. The strip 3 is curved between the two stamping devices 1, and the lowest point of the curved strip 3 is less than the height of the worktable 11 of the stamping device 1. Therefore, the first distance sensor 21 can be flush with the worktable 11 or slightly lower than the worktable 11. That is, the height of the first distance sensor 21 relative to the placement surface is less than or equal to the height of the worktable 11 of the stamping device 1 relative to the placement surface, so as to ensure that the first distance sensor 21 is located above the strip 3 and can detect the strip 3.

[0062] Understandably, the height of the first distance sensor 21 should not differ too much from the height of the worktable 11. In other words, the height of the first distance sensor 21 should not be too low to avoid the first distance sensor 21 interacting with the conveyor belt 3, causing wear and tear on the first distance sensor 21 and affecting its detection efficiency.

[0063] Furthermore, the setting height of the first distance sensor 21 cannot be higher than the setting height of the worktable 11. Since the lowest point of the material belt 3 is lower than the height of the worktable 11, if the setting height of the first distance sensor 21 is higher than the setting height of the worktable 11, the distance between the first distance sensor 21 and the material belt 3 will increase, which may affect the detection efficiency of the first distance sensor 21 on the material belt 3.

[0064] In summary, this embodiment of the application improves the detection efficiency of the first distance sensor 21 on the material strip 3 by setting the height of the first distance sensor 21 relative to the placement surface of the stamping equipment A to be less than or equal to the height of the worktable surface 11 of the stamping device 1 relative to the placement surface.

[0065] In one embodiment, the height difference between the first ranging sensor 21 and the workbench 11 relative to the placement surface is within the range of 0 to 30 cm. That is, the setting height of the first ranging sensor 21 can be 0 to 30 cm lower than the setting height of the workbench 11. For example, the first ranging sensor 21 can be set flush with the workbench 11, that is, the height difference between the first ranging sensor 21 and the workbench 11 is 0 cm, or the setting height of the first ranging sensor 21 is slightly lower than the setting height of the workbench 11, with a difference of 2 cm, 5 cm, 10 cm, 14 cm, 17 cm, 20 cm, 25 cm, 30 cm, etc. The specific values ​​can be set by the user according to the actual design needs, and this application does not limit this.

[0066] Optionally, the height difference between the second ranging sensor 22 and the placement surface of the stamping device A is within the range of 15 to 30 cm.

[0067] The stamping equipment A can be placed on the ground, meaning the second distance sensor 22 can be installed at a height of 15-30cm above the ground. However, the installation height of the second distance sensor 22 should not be too low. For example, if the height difference between the second distance sensor 22 and the placement surface is less than 15cm, the installation height is too low, making installation difficult for the user. Furthermore, the sensor's proximity to the ground makes it easy to damage during cleaning. Conversely, the installation height should not be too high either. For instance, if the height difference is greater than 30cm, the distance between the first distance sensor 21 and the second distance sensor 22 is too short, affecting the material belt 3's ability to pass between them. This could cause the material belt 3 to interfere with the second distance sensor 22, impacting its conveying efficiency.

[0068] Therefore, in this embodiment, the height difference between the second ranging sensor 22 and the placement surface is limited to the range of 15 to 30 cm to ensure that the second ranging sensor 22 is at an appropriate installation height and can provide good detection results.

[0069] In one embodiment, the height difference between the second ranging sensor 22 and the placement surface can be 15cm, 16cm, 20cm, 22cm, 24cm, 26cm, 27cm, 30cm, etc. The specific value can be set by the user according to the requirements, and this application does not limit it.

[0070] Optionally, the distance between two adjacent stamping devices 1 is in the range of 1 to 1.5 m.

[0071] Specifically, such as Figure 1 As shown, the distance D between two adjacent stamping devices 1 can be 1m, 1.1m, 1.15m, 1.25m, 1.5m, etc., which can be set by the user according to their needs. This application does not impose any restrictions on this.

[0072] In practice, if the distance between two adjacent stamping devices 1 is too small, it will be inconvenient for users to operate. For example, it will be more difficult for users to thread the material strip 3 through the safety detection device 2 between the two stamping devices 1. Furthermore, if the distance between the two adjacent stamping devices 1 is too small, the bending of the material strip 3 between the two stamping devices 1 will be too large, which may exceed the detection area of ​​the distance sensor and fail to guarantee the detection effect of the safety detection device 2. On the other hand, if the distance between the two stamping devices 1 is too large, it will waste workshop space. Therefore, this embodiment limits the distance D between two adjacent stamping devices 1 to the range of 1 to 1.5m to reduce the footprint of the stamping equipment A, while ensuring the operating efficiency of the stamping equipment A and improving the user experience of the stamping equipment A.

[0073] Optionally, the height difference between the worktable surface 11 of two adjacent stamping devices 1 and the placement surface of the stamping equipment A is within the range of -10 to 10 cm.

[0074] As mentioned above, if two adjacent stamping devices 1 are a first stamping device and a second stamping device, then the worktable 11 of the first stamping device can be 0-10cm higher or lower than the worktable 11 of the second stamping device. For example, the worktable 11 of the first stamping device can be flush with the worktable 11 of the second stamping device, or the worktable 11 of the first stamping device can be 1cm, 2cm, 2.5cm, 3cm, 5cm, 7.5cm, 10cm higher or lower than the worktable 11 of the second stamping device, etc., which can be set by the user according to their needs. This application does not impose any restrictions on this.

[0075] In fact, if the height difference between the worktables 11 of two adjacent stamping devices 1 is too large, for example, greater than 10cm, the height difference between the two ends of the curved strip 3 (the part of the strip 3 between the two stamping devices 1) will be too large, which will reduce the conveying efficiency of the strip 3 and affect the detection efficiency of the safety detection device 2 on the strip 3.

[0076] In this embodiment, the height difference between the worktable surface 11 of two adjacent stamping devices 1 and the placement surface is within the range of -10 to 10 cm, which improves the conveying efficiency of the material strip 3 in the stamping equipment A, enhances the stamping efficiency of the material strip 3 in the stamping equipment A, and improves the user's experience of using the stamping equipment A.

[0077] Optionally, in the stamping device 1, the conveying speed of the stamping device 1 to the material strip 3 is positively correlated with the stamping speed of the stamping device 1 to the material strip 3.

[0078] Specifically, the conveying speed of the material strip 3 on the stamping device 1 and the stamping speed of the material strip 3 on the stamping device 1 can be positively correlated. This allows the stamping device 1 to achieve the effect of conveying the material strip 3 a fixed distance with each stamping operation, thus coordinating the stamping and conveying of the material strip 3. This enables the stamping device 1 to regularly stamp the material strip 3, ensuring that any two adjacent stamped positions on the material strip 3 are equidistant.

[0079] Since the safety detection device 2 can ensure that the conveying speed of the material strip 3 between two adjacent stamping devices 1 is equal, that is, the stamping speed of the material strip 3 by the two adjacent stamping devices 1 will also be equal, ensuring that the stamping cycle of the two adjacent stamping devices 1 is equal. For example, if the two adjacent stamping devices 1 include a first stamping device and a second stamping device, then the stamping cycle of the first stamping device and the second stamping device is equal. That is, the stamping position of the second stamping device on the material strip 3 can fall on the stamping position of the first stamping device on the material strip 3, and cooperate to stamp the material strip 3 to obtain the required metal part.

[0080] Understandably, since the conveying speed of the stamping device 1 to the material strip 3 is positively correlated with the stamping speed of the stamping device 1 to the material strip 3, that is, when the stamping device 1 adjusts the conveying speed, it will also adjust the stamping speed. Therefore, after the safety detection device 2 detects the difference in the conveying speed of the material strip 3 between two adjacent stamping devices 1, the stamping device 1 will adjust its conveying speed and its stamping speed simultaneously, thereby improving the synchronization of the operation of multiple stamping devices 1 in stamping equipment A and improving the operational stability and efficiency of stamping equipment A.

[0081] In one embodiment, the power component of the strip conveying mechanism in the stamping device 1 and the power component of the stamping power mechanism can be connected by a connecting component to realize that the conveying speed of the strip conveying mechanism on the strip 3 is related to the stamping speed of the stamping power mechanism on the strip 3.

[0082] In summary, the stamping equipment A provided in this application, by setting a safety detection device 2 between two adjacent stamping devices 1, detects the difference in conveying speed of the material strip 3 between the two adjacent stamping devices 1, ensuring that the conveying speed of the material strip 3 between the two adjacent stamping devices 1 is equal. This eliminates the need for the prior art, which requires connecting the stamping shafts of two adjacent stamping devices with couplings to ensure synchronous operation. This necessitates modifications to the power shafts of the stamping devices to allow them to connect with the power shafts of other stamping devices, resulting in complex preliminary preparations.

[0083] This application ensures the synchronous operation of two adjacent stamping devices 1 by setting up a safety detection device 2. This allows for the direct use of a single stamping device 1 without requiring any modifications to the stamping device 1 to stamp the same material strip 3 as other stamping devices 1. This simplifies the installation of the stamping equipment A and enables the stamping of longer material strips 3, improving the user experience. Furthermore, the safety detection device 2 can control the stamping device 1 to stop promptly when the conveying speeds of the two adjacent stamping devices 1 are inconsistent, or when there is a shortage of material, preventing damage to the stamping device 1 and improving the safety of the stamping equipment A.

[0084] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
