[0026] The present invention has the following beneficial effects:

[0027] 1. The stamping die detection equipment has a vertical rod installed on the electric slider. When the electric slider moves, the vertical rod drives the rotating plate to move, and the rotating plate pushes the movable support to move through the No. 2 compression spring. During the movement of the movable support, the first protrusion will conflict with the second protrusion. During the conflict between the first protrusion and the second protrusion, the movable support and the stamping die will no longer move, and then the stamping upper die performs stamping operation on the stamping die. At the same time, the push rod pushes the No. 2 compression spring to compress and accumulate force. When the stamping work is completed and the No. 2 compression spring is compressed to a certain extent, the second protrusion is deformed and breaks through the first protrusion. The stamping die moves forward and reaches the detection area. At this time, the laser detector is triggered to detect the degree of wear of the stamping die. This process automatically detects the stamping die of the die, does not require manual operation, avoids manual disassembly and assembly of the stamping die, and has high safety.

[0028] 2. The stamping die detection equipment, when the outer rack is meshed with the outer gear, the outer gear drives the stamping die to deflect through the engagement of the No. 2 ratchet ring and the No. 2 pawl. When the deflection of the stamping die reaches the maximum position, the laser detector performs wear detection on the edge position of the stamping die. When the inner rack drives the inner gear to rotate, the No. 1 pawl engages with the No. 1 ratchet ring, thereby driving the stamping die to deflect in the opposite direction and performing wear detection on the other edge of the stamping die. Moreover, the edge positions of the stamping die after two deflections coincide and are both located at the detection point of the laser detector. At this time, only one laser detector is needed to complete the detection of both sides of the stamping die, thereby increasing the practicality of the device.

[0029] 3. The stamping die inspection equipment, after the stamping is completed, the mobile support drives the stamping die to continue to move forward. When the vertical rod moves to the tail end of the outward through-groove, the vertical rod enters the first oblique through-groove under the push of the No. 1 compression spring, and then the electric slider moves in the opposite direction to bring the vertical rod to the return through-groove, and the height of the return slide gradually decreases, so that the mobile support can quickly reset following the vertical rod. When the vertical rod moves to the tail end of the return through-groove, the No. 1 wedge block slides in contact with the No. 2 wedge block, so that the vertical rod can smoothly enter the second oblique through-groove, thereby achieving the purpose of resetting the vertical rod and the mobile support.

Specific implementation mode

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1. The purpose of this embodiment is to solve the problem that the common detection of stamping dies mainly uses manual inspection. After stamping for a period of time, the operator needs to remove the die and manually measure the wear degree of the die. This method not only consumes manpower, but also has certain safety risks in the manual disassembly and assembly of the die. Please refer to Figures 1 to 13A stamping die detection device includes a base 101 and a detection bracket 108, a stamping bracket 104 is installed on the base 101, a hydraulic cylinder 105 is arranged on the stamping bracket 104, a stamping upper die 106 is installed on the piston rod of the hydraulic cylinder 105, a stamping die 109 is arranged below the stamping upper die 106, wherein the stamping upper die 106 and the stamping die 109 stamp the stamping part together, a laser detector 107 for detecting the stamping die 109 is installed on the detection bracket 108, the detection bracket 108 is installed on the base 101, a guide rail 303 is installed on the base 101, an electric slider 301 is installed on the guide rail 303, the stamping die 109 is installed on the electric slider 301, and after the stamping die 109 performs stamping work, it moves with the electric slider 301 to the bottom of the laser detector 107 for detection.

[0046] Among them, the laser detector 107 emits a laser beam to the edge of the stamping die 109 at a certain angle. When the laser irradiates the edge of the stamping die 109, a light spot is formed, and the light spot will produce reflection. There is a sensor for detecting the reflected laser on the reflected light path. If the edge of the stamping die 109 is flat, the reflected light returns at a fixed angle, and the position of the light spot received by the sensor is also fixed. However, if the edge of the stamping die 109 has a height change, the angle of the reflected light will change, and the position of the light spot received by the sensor will also change accordingly, thereby realizing the effect of detecting the wear and deformation of the stamping die 109. Using the laser detector 107 to perform shape detection on the stamping die 109 is a common technical means in this field and is well known to those skilled in the art, so it will not be elaborated here.

[0047] For details, please refer to Figure 1 A mounting bracket 103 is installed on the base 101, a stamping table 102 is arranged on the mounting bracket 103, a slide 400 is arranged on the stamping table 102, a movable support 201 is slidably installed on the slide 400, a stamping die 109 is installed on the movable support 201, and the bottom end of the stamping die 109 is in sliding contact with the slide 400, and the movable support 201 is transmission-connected to the electric slider 301.

[0048] For details, please refer to Figure 4 , Figure 12 A vertical rod 202 is installed on the electric slider 301, a rotating plate 203 is installed on the side of the movable support 201, and a through groove 500 is opened on the slide 400. The vertical rod 202 is inserted into the through groove 500, and the vertical rod 202 slides and inserts the rotating plate 203.

[0049] Also, please refer to Figure 7, on both sides of the movable support 201, there are first sleeves 209 installed. A push rod 204 is slidably installed in the first sleeve 209. A second compression spring 221 is arranged in the first sleeve 209. One end of the push rod 204 abuts against the second compression spring 221. The rotating plate 203 is installed on the two push rods 204. A second convex block 212 is installed on the bottom side of the first sleeve 209. A first convex block 211 is arranged on the sliding table 400. The second convex block 212 abuts against the first convex block 211, and the second convex block 212 and the first convex block 211 are arranged as elastic rubber convex blocks.

[0050] In this embodiment: A vertical rod 202 is installed on the electric slider 301. When the electric slider 301 moves, the vertical rod 202 drives the rotating plate 203 to move. The rotating plate 203 pushes the movable support 201 to move through the second compression spring 221. During the movement of the movable support 201, the first convex block 211 will abut against the second convex block 212. During the abutment between the first convex block 211 and the second convex block 212, the movable support 201 and the stamping die 109 no longer move. Then the upper stamping die 106 performs stamping operations on the stamping die 109. At the same time, the push rod 204 pushes the second compression spring 221 to compress and store energy. When the stamping work is completed and the second compression spring 221 is compressed to a certain extent, the second convex block 212 deforms and breaks through the first convex block 211. The stamping die 109 moves forward and reaches the detection area. At this time, the laser detector 107 is triggered to detect the wear degree of the stamping die 109. This process automatically detects the stamping die 109 of the mold, without manual operation, avoiding the manual disassembly and assembly operation of the stamping die 109, and having relatively high safety.

[0051] Embodiment 2. The intention of this embodiment is to promote the solution of the problem of how to automatically detect both sides of the stamping die 109 in one detection due to severe wear on both sides of the stamping die 109, which is the key detection area. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 to 13 , a driving rack 208 is installed on the side of the first sleeve 209. A energy storage gear 205 is rotatably installed on the stamping table 102. The driving rack 208 meshes with the energy storage gear 205. An outer rack 219 is slidably installed on the stamping table 102. The outer rack 219 is set as a double-tooth rack. An outer gear 206 for deflecting the stamping die 109 is rotatably installed on the movable support 201. The rotating shaft of the outer gear 206 passes through the movable support 201 and is fixedly connected to the stamping die 109. The energy storage gear 205 meshes with the outer rack 219. The outer gear 206 meshes with the outer rack 219. A groove 406 for allowing the stamping die 109 to deflect smoothly is formed on the sliding table 400.

[0052] Among them, please refer to Figure 6 、 Figure 7, a winding spring 220 is installed on the energy storage gear 205. The winding spring 220 is set as a volute spring. One end of the winding spring 220 is fixedly connected to the stamping table 102, and the other end of the winding spring 220 is fixedly installed on the rotating shaft of the energy storage gear 205. The length of the upper teeth of the external rack 219 is half of the length of the lower teeth. An internal rack 218 is installed on the side of the external rack 219. An internal gear 207 is coaxially installed on the rotating shaft of the external gear 206. The external gear 206 meshes with the external rack 219, and the internal gear 207 meshes with the internal rack 218. A first pawl 214 is hinged on the rotating shaft of the external gear 206, and a second pawl 215 is also hinged on the rotating shaft of the external gear 206. A first ratchet ring 216 is installed on the internal gear 207, and the first ratchet ring 216 is movably engaged with the first pawl 214. A second ratchet ring 217 is installed on the external gear 206, and the second ratchet ring 217 is movably engaged with the second pawl 215. Both the external gear 206 and the internal gear 207 drive the stamping die 109 to deflect, and the deflection directions are opposite.

[0053] It should be noted that both the first pawl 214 and the second pawl 215 are hinged on the rotating shaft of the external gear 206. The first pawl 214 and the second pawl 215 can rotate unidirectionally through spring cooperation, and the rotation directions of the first pawl 214 and the second pawl 215 are opposite, so that the rotation directions of the first ratchet ring 216 and the second ratchet ring 217 are opposite. The mechanical cooperation of the ratchet and pawl is a conventional mechanical cooperation means and will not be elaborated here.

[0054] It should be noted that, please refer to Figure 9, when the moving support 201 moves forward, the driving rack 208 meshes with the energy storage gear 205. The energy storage gear 205 drives the outer rack 219 to move backward. The outer rack 219 further drives the outer gear 206 to rotate. At this time, the teeth of the second pawl 215 and the second ratchet ring 217 are engaged, so that the outer gear 206 drives the rotating shaft of the outer gear 206 to rotate, achieving the rotating effect of the stamping die 109. Since the length of the upper teeth of the outer rack 219 is half of the length of the lower teeth, the outer gear 206 will stop rotating after disengaging from the outer rack 219 (at this time, although the inner gear 207 and the inner rack 218 are meshed, the teeth of the first pawl 214 and the first ratchet ring 216 are not engaged, so the inner gear 207 will not cause the stamping die 109 to rotate). At this time, the stamping die 109 is in a static state, and the laser detector 107 detects one side edge of the stamping die 109. When the moving support 201 continues to move forward, the driving rack 208 and the energy storage gear 205 are disengaged. At this time, the energy storage gear 205 rotates in the reverse direction compared with before under the drive of the spring 220, so that the energy storage gear 205 drives the outer rack 219 to move forward. At the same time, the inner rack 218 installed on the side of the outer rack 219 also moves forward. Then, the inner rack 218 meshes with the inner gear 207, and the teeth of the first pawl 214 and the first ratchet ring 216 are engaged. Therefore, when the inner rack 218 drives the inner gear 207 to rotate, the inner gear 207 drives the stamping die 109 to rotate in the reverse direction compared with before. Also, since the inner rack 218 and the outer rack 219 are of equal length, and the length of the upper teeth of the outer rack 219 is half of the length of the lower teeth, the rotation angle of the inner gear 207 is twice the rotation angle of the outer gear 206 before. Thus, the edges of the stamping die 109 coincide after two deflections, and the coincidence point is located at the detection point of the laser detector 107.

[0055] Since the stamping die 109 is in an inclined state after two deflections, for subsequent stamping operations, it is necessary to correct the stamping die 109. Therefore, a reset rack 213 is fixedly installed on the stamping table 102. When the reset rack 213 meshes with the outer gear 206, it drives the stamping die 109 to reset, making the stamping die 109 in a horizontal state. Similarly, during implementation, the length of the reset rack 213 is set to be half of the length of the outer rack 219.

[0056] In this embodiment: When the second bump 212 deforms and breaks through the first bump 211, the driving rack 208 meshes with the energy storage gear 205. While the energy storage gear 205 rotates, the spring 220 stores energy. Moreover, the energy storage gear 205 meshes with the outer rack 219, the outer rack 219 meshes with the outer gear 206, and the outer gear 206 drives the stamping die 109 to deflect through the engagement of the second ratchet ring 217 and the second pawl 215. When the deflection of the stamping die 109 reaches the maximum position, the laser detector 107 detects the wear of the edge position of the stamping die 109. During this process, the first pawl 214 and the first ratchet ring 216 do not engage, so the rotation of the internal gear 207 and the rotation of the outer gear 206 do not conflict;

[0057] When the driving rack 208 continues to move forward and no longer meshes with the energy storage gear 205, at this time the spring 220 drives the energy storage gear 205 to rotate in the reverse direction. At this time, the internal rack 218 drives the internal gear 207 to rotate, and the first pawl 214 engages with the first ratchet ring 216, thereby driving the stamping die 109 to deflect in the reverse direction and detecting the wear of another edge of the stamping die 109. Compared with directly detecting the stamping die 109, deflecting the edge of the stamping die 109 outward enables the laser detector 107 to better align with the edge position of the stamping die 109. Moreover, the edge positions after the two deflections of the stamping die 109 coincide and are both located at the detection point of the laser detector 107. At this time, only one laser detector 107 is needed to complete the detection of both sides of the stamping die 109, so the practicability of this device is increased.

[0058] Embodiment 3. The intention of this embodiment is to facilitate the solution of the problem of the rapid return and reset of the stamping die 109 after detection. This embodiment is an improvement made on the basis of Embodiment 2. Specifically, please refer to Figures 1 to 13 , the sliding table 400 includes a forward sliding table 401 and a return sliding table 402. The forward sliding table 401 and the return sliding table 402 are arranged in parallel. The elevation of the tail end of the forward sliding table 401 is higher than that of the head end, and the elevation of the return sliding table 402 gradually decreases. After stamping, the moving support 201 enters the return sliding table 402, and the moving support 201 drives the stamping die 109 to quickly reset.

[0059] It should be noted that after the detection of the stamping die 109 in this embodiment, the stamping die 109 can be quickly reset. However, according to the specific situation and the accuracy requirements for the stamping die 109, the detection frequency of the stamping die 109 can be changed. Specifically, if the accuracy requirements for the stamping die 109 are relatively high, then the stamping die 109 is detected once every 5 - 10 stamping operations. On the contrary, if the accuracy requirements for the stamping die 109 are relatively low, then the stamping die 109 is detected once every 70 - 100 stamping operations.

[0060] Among them, a chute 305 is formed on the electric slider 301, a slider 307 is slidably installed in the chute 305, a vertical rod 202 is fixedly installed on the slider 307, and the vertical rod 202 is slidably abutted against the through groove 500. A baffle 302 is installed on the electric slider 301, a first compression spring 304 is arranged on the baffle 302, one end of the slider 307 is fixedly connected to the first compression spring 304. A second sleeve 505 is installed at the bottom of the stamping table 102, a third compression spring 507 is arranged in the second sleeve 505, a second wedge-shaped block 506 is slidably installed in the second sleeve 505, one end of the second wedge-shaped block 506 is fixedly connected to the third compression spring 507, and one end of the slider 307 is installed with a first wedge-shaped block 306, and the first wedge-shaped block 306 is in sliding contact with the second wedge-shaped block 506.

[0061] In addition, the through groove 500 includes a forward stroke through groove 501, a first inclined through groove 502, a return stroke through groove 503, and a second inclined through groove 504. The forward stroke through groove 501, the first inclined through groove 502, the return stroke through groove 503, and the second inclined through groove 504 are connected in sequence. Under the action of the first compression spring 304, the vertical rod 202 abuts against the inner wall of the through groove 500. Therefore, the first inclined through groove 502 is provided to make it smoother for the vertical rod 202 to enter the return stroke through groove 503 from the forward stroke through groove 501. Similarly, the first inclined through groove 502 makes it smoother for the vertical rod 202 to enter the forward stroke through groove 501 from the return stroke through groove 503.

[0062] In this embodiment: After stamping is completed, the moving support 201 drives the stamping die 109 to continue moving forward. When the vertical rod 202 moves to the end of the forward stroke through groove 501, the vertical rod 202 enters the first inclined through groove 502 under the push of the first compression spring 304. Then the electric slider 301 moves in the reverse direction to bring the vertical rod 202 into the return stroke through groove 503, and the elevation of the return slide 402 gradually decreases, so as to facilitate the rapid reset of the moving support 201 following the vertical rod 202. When the vertical rod 202 moves to the end of the return stroke through groove 503, the first wedge-shaped block 306 is in sliding contact with the second wedge-shaped block 506, so that the vertical rod 202 can smoothly enter the second inclined through groove 504, thus achieving the purpose of resetting the vertical rod 202 and the moving support 201.
