Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a sensing and positioning device for a stamping die. Background Technology

[0002] In the field of stamping production, traditional stamping die design has long been limited by the reliance on manual observation or simple mechanical limits for positioning detection, which makes it impossible to accurately determine the position of the sheet metal in real time. This often results in scrap or even damage to the die due to positioning deviation. Furthermore, the warning function of traditional sensing positioning devices is missing or limited, making it difficult to quickly alert to abnormalities in noisy workshop environments, which can easily lead to safety accidents. Existing publication number CN204486601U discloses an induction-type stamping die and its sheet metal positioning device. The latter includes a support assembly mounted on the die body, a movable positioning plate mounted on the support assembly, and an induction plate rotatably mounted on the movable positioning plate via a first rotating shaft. The induction plate matches a sensor and is rotatably mounted on the support assembly via a second rotating shaft. The movable positioning plate is slidably mounted on the support assembly, and the sliding direction of the movable positioning plate is towards or away from the sensor. The first rotating shaft extends horizontally and is perpendicular to the sliding direction of the movable positioning plate. The first rotating shaft is located below the sensor. The induction plate rotates around the second rotating shaft in a vertical plane and senses or de-senses with the sensor. Thus, the movable positioning plate has a small structure and an inward-retracting motion form, resulting in a small movement trajectory, thereby reducing the range of the die's clearance and reducing the processing difficulty of the die's clearance part, improving the pressing effect of the sheet metal blank. In the process of realizing this utility model, the inventors discovered the following problems with the prior art: Existing sensing and positioning devices lack sensing structures for positioning detection, relying mostly on manual visual observation or simple mechanical limits. They cannot detect the positioning status of the sheet metal in real time, nor can they determine whether the sheet metal is placed in place. Positioning deviations often lead to stamping scraps and even damage to the molds. In terms of warning functions, traditional designs often lack dedicated warning components or only have a single sound warning. In noisy workshop environments, a single warning method is easily overlooked by operators, failing to promptly remind them of abnormal sheet metal positioning, leading to continuous equipment operation and causing safety accidents or equipment failures. Therefore, a sensing and positioning device for stamping dies is proposed to address the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sensing and positioning device for stamping dies to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sensing and positioning device for a stamping die, comprising an upper die, a lower die, a sensing component, and a warning component. The lower die is installed below the upper die, and the sensing component is installed on the side of the lower die. The warning component is installed on the side of the lower die away from the sensing component. The upper die includes an upper template, a triggering component, and a fixing ring. The fixing ring is installed above the upper template, and the triggering component is installed on the side of the upper template.

[0005] Preferably, the triggering component includes an upper closing ring, a rubber pad, and a trigger post, with the rubber pad installed below the upper closing ring and the trigger post installed below the rubber pad.

[0006] Preferably, the lower mold includes a lower template, a lower closing plate, and a guide assembly, and the lower closing plate is installed on the side of the lower template, and the guide assembly is installed above the lower closing plate.

[0007] Preferably, the guide assembly includes a guide post, a guide sleeve, and a fixing post, wherein the guide sleeve is installed on the outer diameter surface of the guide post, and the fixing post is installed below the guide sleeve.

[0008] Preferably, the sensing component includes a pressure sensor, a spring, and a sensing block, with the spring mounted above the pressure sensor and the sensing block mounted above the spring.

[0009] Preferably, the warning assembly includes a buzzer, a warning light, and a mounting plate, with the buzzer mounted on top of the mounting plate and the warning light located on the side of the buzzer.

[0010] Preferably, four sets of guide posts are provided, and the guide posts and the guide sleeve are in clearance fit, and the guide posts and the fixed posts are connected by welding.

[0011] Preferably, the fixing plate and the buzzer are connected by bolts, and the fixing plate and the warning light are connected by bolts. The fixing plate is a rectangular plate structure.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this inductive positioning device for stamping dies uses four sets of guide pillars evenly distributed above the lower closing plate to form a stable rectangular guide frame. This allows for all-round positioning of the upper die from four directions, preventing unilateral deviation when the upper die moves downward. At the same time, the guide pillars and guide sleeves are fitted with a clearance, which ensures smooth relative sliding between the two, reduces frictional wear during long-term use, and ensures the guiding direction through clearance control, preventing guide wobbling caused by excessive clearance.

[0013] Compared with existing technologies, this inductive positioning device for stamping dies uses a rectangular plate as the mounting carrier for the warning component. The plate is firmly connected to the buzzer and warning light by bolts, ensuring that the warning component is stably installed during equipment operation and avoiding warning failure due to vibration. When the inductive component detects abnormal positioning of the sheet metal, the pressure sensor in the inductive component will transmit the abnormal pressure signal to the controller. The controller will quickly trigger the warning component. At this time, the buzzer will sound an alarm, and the warning light will illuminate to form a visual warning. This dual warning method of sound and light can effectively adapt to different workshop environments. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] As attached Figures 1 to 4The sensor positioning device for a stamping die shown includes an upper die 1, a lower die 2, a sensor component 3, and a warning component 4. The lower die 2 is installed below the upper die 1, the sensor component 3 is installed on the side of the lower die 2, and the warning component 4 is installed on the side of the lower die 2 away from the sensor component 3. The upper die 1 includes an upper template 5, a trigger component 6, and a fixing ring 7. The fixing ring 7 is installed above the upper template 5, and the trigger component 6 is installed on the side of the upper template 5.

[0021] The stamping die's sensing and positioning device is structured with the upper die 1 and lower die 2 as a frame, with the lower die 2 located below the upper die 1, forming a basic stamping die-closing structure. Simultaneously, sensing components 3 and warning components 4 are installed on both sides of the lower die 2, creating a functional linkage system for positioning detection and abnormal warning. The upper die 1 integrates an upper template 5, a trigger component 6, and a fixing ring 7. The fixing ring 7 is installed above the upper template 5 to ensure a stable connection between the upper die 1 and external stamping equipment. The trigger component 6 is mounted on the side of the upper template 5, serving as a key triggering component for positioning sensing. When stamping begins, the upper die 1 drives the trigger component 6 downwards, contacting the sensing component 3 on the side of the lower die 2. The sensing component 3 detects and judges the sheet metal positioning status. If positioning is abnormal, the sensing component 3 transmits a signal to the warning component 4, which then activates its warning function. If positioning is normal, the upper die 1 and lower die 2 successfully complete the die-closing stamping. The entire process achieves the dual goals of positioning and safe stamping through the coordinated cooperation of all components. Example 2

[0022] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the triggering component 6 includes an upper closing ring 8, a rubber pad 9, and a triggering post 10. The rubber pad 9 is installed below the upper closing ring 8, and the triggering post 10 is installed below the rubber pad 9. The triggering component 6 adopts a three-layer stacked structure. The upper closing ring 8 serves as the connection base between the triggering component 6 and the upper template 5. The rubber pad 9 is located between the upper closing ring 8 and the triggering post 10, and plays a buffering role against the collision between the upper mold 1 and the lower mold 2 when they are closed. The triggering post 10 serves as the actuator that directly contacts the sensing component 3. When the upper mold 1 moves downward, the triggering post 10 moves with the upper mold 1 and eventually contacts the sensing component 3 to achieve positioning triggering.

[0023] In a preferred embodiment, the lower mold 2 includes a lower template 11, a lower closing plate 12, and a guide assembly 13. The lower closing plate 12 is installed on the side of the lower template 11, and the guide assembly 13 is installed above the lower closing plate 12. The lower template 11 serves as the base support plate of the lower mold 2, providing a support surface for sheet metal stamping. The lower closing plate 12 is installed on the side of the lower template 11, which not only reinforces the lower template 11 but also serves as the mounting carrier for the guide assembly 13. The guide assembly 13 is installed above the lower closing plate 12, providing guidance for the upper mold 1 to descend and close, ensuring that the upper mold 1 and the lower mold 2 are aligned.

[0024] In a preferred embodiment, the guide assembly 13 includes a guide post 14, a guide sleeve 15, and a fixed post 16. The guide sleeve 15 is installed on the outer diameter surface of the guide post 14, and the fixed post 16 is installed below the guide sleeve 15. The fixed post 16 serves as the mounting base for the guide assembly 13 and is connected to the lower closing plate 12 to fix the guide assembly 13. The guide post 14 is connected to the fixed post 16, and the guide sleeve 15 is sleeved on the outer diameter surface of the guide post 14. When the upper mold 1 moves downward, the corresponding structure on the upper mold 1 cooperates with the guide sleeve 15. Through the relative sliding of the guide post 14 and the guide sleeve 15, the upper mold 1 is guided to move downward along a fixed trajectory to achieve mold closing.

[0025] In a preferred embodiment, the sensing component 3 includes a pressure sensor 17, a spring 18, and a sensing block 19. The spring 18 is mounted above the pressure sensor 17, and the sensing block 19 is mounted above the spring 18. The pressure sensor 17, as the signal detection core, is fixed to the side of the lower mold 2. The spring 18 is mounted above the pressure sensor 17, and the sensing block 19 is mounted above the spring 18. When the trigger post 10 moves downward and contacts the sensing block 19, the sensing block 19 is pressed and transmits the pressure to the spring 18. After the spring 18 is compressed, it further transmits the pressure to the pressure sensor 17. After detecting the pressure signal, the pressure sensor 17 determines whether the sheet metal is positioned correctly. If the upper mold 1 and the lower mold 2 complete the mold closing process, the pressure value received by the pressure sensor 17 is a fixed value, indicating that the sheet metal position is correct.

[0026] In a preferred embodiment, the warning component 4 includes a buzzer 20, a warning light 21, and a fixing plate 22. The buzzer 20 is mounted on the top of the fixing plate 22, and the warning light 21 is provided on the side of the buzzer 20. The fixing plate 22 serves as the mounting carrier for the warning component 4 and is connected to the lower mold 2 to fix the warning component 4. The buzzer 20 and the warning light 21 are mounted on the fixing plate 22. When the sensing component 3 detects an abnormality in the positioning of the sheet metal, the sensing component 3 transmits the abnormality signal to the controller. The controller triggers the buzzer 20 to sound and the warning light 21 to light up, thus providing a dual warning through sound and light to remind the operator to handle the abnormality in a timely manner.

[0027] In a preferred embodiment, four sets of guide posts 14 are provided, the guide posts 14 and the guide sleeves 15 are in clearance fit, and the guide posts 14 and the fixed posts 16 are connected by welding.

[0028] In a preferred embodiment, the fixing plate 22 and the buzzer 20 are connected by bolts, and the fixing plate 22 and the warning light 21 are connected by bolts. The fixing plate 22 is a rectangular plate structure.

[0029] In this embodiment, the pressure sensor 17 and the buzzer 20 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0030] The working process of this utility model is as follows: First, when the operator uses the equipment to stamp objects, he / she must first confirm that the upper mold 1 and the lower mold 2 are in the mold separation state, check whether the fixing ring 7 above the upper template 5 is firmly connected to the external stamping equipment, and then place the object to be stamped stably on the lower template 11.

[0031] Next, the equipment is started. The upper mold 1 drives the trigger component 6 on the side of the upper template 5. The trigger component 6 consists of an upper closing ring 8, a rubber pad 9, and a trigger post 10. The upper closing ring 8 is the connecting base, and the rubber pad 9 is located in the middle. When the upper mold 1 moves downward, the guide post 14 on the upper mold 1 cooperates with the guide sleeve 15 in the guide component 13 above the lower closing plate 12. The guide post 14 and the guide sleeve 15 of the guide component 13 slide relative to each other through clearance cooperation, guiding the upper mold 1 to move downward along a fixed trajectory.

[0032] When the trigger post 10 contacts the sensing block 19 in the sensing component 3 on the side of the lower mold 2, the sensing block 19 is pressed and transmits the pressure to the spring 18 below. After the spring 18 is compressed, it transmits the pressure to the pressure sensor 17. The pressure sensor 17 detects the pressure value. If the object is positioned normally, the pressure value is fixed, and the upper mold 1 continues to descend and completes the mold closing and stamping with the lower mold 2. If the object is positioned abnormally, the sensing component 3 will transmit a signal to the controller, and the controller will trigger the warning component 4. At this time, the buzzer 20 will sound and the warning light 21 will light up. The operator needs to stop the machine and adjust the position of the object. After the stamping is completed, the upper mold 1 drives the trigger component 6 to move upward and reset. The sensing block 19 returns to its original position under the action of the spring 18. The operator takes out the stamped object and completes one stamping operation. The above is the working principle of the sensing and positioning device of this stamping mold.
