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.

[0017] 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.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: This embodiment aims to solve the problem that the common stamping die inspection mainly relies on manual inspection. After a period of stamping processing, the operator needs to remove the die and manually measure the degree of wear of the die. This method not only consumes manpower, but also has certain safety risks in manual disassembly and assembly of the die. Please refer to Figures 1 to 13 A 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.

[0033] 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.

[0034] For details, please refer to Figure 1A 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.

[0035] For details, please refer to Figure 4 , Fig.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.

[0036] Also, please refer to Figure 7 A first sleeve 209 is installed on both sides of the movable support 201, a push rod 204 is slidably installed in the first sleeve 209, a No. 2 compression spring 221 is provided in the first sleeve 209, one end of the push rod 204 is in conflict with the No. 2 compression spring 221, the rotating plate 203 is installed on the two push rods 204, a second protrusion 212 is installed on the bottom side of the first sleeve 209, a first protrusion 211 is provided on the slide 400, the second protrusion 212 is in conflict with the first protrusion 211, and the second protrusion 212 and the first protrusion 211 are set as elastic rubber protrusions.

[0037] 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 protrusion 211 will conflict with the second protrusion 212. During the conflict between the first protrusion 211 and the second protrusion 212, the movable support 201 and the stamping die 109 no longer move, and then the stamping upper die 106 stamps the stamping die 109. Operation, at the same time, the push rod 204 pushes the second compression spring 221 to compress and accumulate force. When the stamping work is completed and the second compression spring 221 is compressed to a certain extent, the second protrusion 212 is deformed and breaks through the first protrusion 211. The stamping die 109 moves forward and reaches the detection area. At this time, the laser detector 107 is triggered to detect the degree of wear of the stamping die 109. This process automatically detects the stamping die 109 of the mold without manual operation, avoids manual disassembly and assembly of the stamping die 109, and has higher safety.

[0038] Embodiment 2: This embodiment is intended to promote the solution of the problem of how to automatically detect both sides of the stamping die 109 in one detection because both sides of the stamping die 109 are severely worn and are the key detection areas. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 13 A driving rack 208 is installed on the side of the first sleeve 209, and an energy storage gear 205 is rotatably installed on the stamping table 102, and the driving rack 208 is meshed with the energy storage gear 205. An external rack 219 is slidably installed on the stamping table 102, and the external rack 219 is set as a double-tooth rack. An external gear 206 for deflecting the stamping die 109 is rotatably installed on the movable support 201, and the rotating shaft of the external gear 206 passes through the movable support 201 and is fixedly connected to the stamping die 109, the energy storage gear 205 is meshed with the external rack 219, and the external gear 206 is meshed with the external rack 219. A groove 406 for smoothly deflecting the stamping die 109 is opened on the slide 400.

[0039] Among them, please refer to Figure 6 , Figure 7 A spring 220 is installed on the energy storage gear 205. The spring 220 is set as a spiral spring. One end of the spring 220 is fixedly connected to the stamping table 102, and the other end of the spring 220 is fixedly installed on the rotating shaft of the energy storage gear 205. The upper teeth length of the outer rack 219 is half of the lower teeth length. The side of the outer rack 219 is installed with an inner rack 218. The rotating shaft of the outer gear 206 is coaxially installed with an inner gear 207. The outer gear 206 is meshed with the outer rack 219, and the inner gear 207 is meshed with the inner rack. 218 are engaged, a No. 1 pawl 214 is hinged on the rotating shaft of the external gear 206, and a No. 2 pawl 215 is also hinged on the rotating shaft of the external gear 206, a No. 1 ratchet ring 216 is installed on the internal gear 207, and the No. 1 ratchet ring 216 is movably engaged with the No. 1 pawl 214, a No. 2 ratchet ring 217 is installed on the external gear 206, and the No. 2 ratchet ring 217 is movably engaged with the No. 2 ratchet ring 215, and both the external gear 206 and the internal gear 207 drive the stamping die 109 to deflect, and the deflection directions are opposite.

[0040] It should be noted that the No. 1 pawl 214 and the No. 2 pawl 215 are both hinged on the rotating shaft of the external gear 206, and the No. 1 pawl 214 and the No. 2 pawl 215 can rotate unidirectionally through spring cooperation, and the rotation directions of the No. 1 pawl 214 and the No. 2 pawl 215 are opposite, so that the rotation directions of the No. 1 ratchet ring 216 and the No. 2 ratchet ring 217 are opposite, and the mechanical cooperation of the ratchet and pawl is a conventional mechanical cooperation means, which will not be elaborated here.

[0041] Please note that, please refer to Fig. 9When the movable support 201 moves forward, the driving rack 208 and the energy storage gear 205 are meshed, and the energy storage gear 205 drives the outer rack 219 to move backward, and the outer rack 219 further drives the outer gear 206 to rotate. At this time, the teeth of the second ratchet 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, thereby realizing the rotation effect of the stamping die 109. Since the upper side tooth length of the outer rack 219 is When the outer gear 206 loses meshing with the outer rack 219, it stops rotating (although the inner gear 207 and the inner rack 218 are meshing, the teeth of the No. 1 pawl 214 and the No. 1 ratchet ring 216 are not engaged, so the inner gear 207 does not cause the stamping die 109 to rotate). At this time, the stamping die 109 is stationary, and the laser detector 107 detects one side edge of the stamping die 109. When the mobile support 201 continues to move forward, The drive rack 208 and the energy storage gear 205 lose meshing. At this time, the energy storage gear 205 rotates in the opposite direction compared with the previous rotation under the drive of the mainspring 220, so that the energy storage gear 205 drives the outer rack 219 to move forward, and the inner rack 218 installed on the side of the outer rack 219 also moves forward, so that the inner rack 218 meshes with the inner gear 207, and the teeth of the No. 1 pawl 214 and the No. 1 ratchet ring 216 are engaged, so the inner rack 218 drives the inner gear 207 to move forward. When the movable internal gear 207 rotates, the internal gear 207 drives the stamping die 109 to rotate in the opposite direction compared to before. 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 internal gear 207 is twice the previous rotation angle of the outer gear 206, thereby achieving the overlap of the edges of the stamping die 109 after two deflections, and the overlap point is located at the detection point of the laser detector 107.

[0042] Since the stamping die 109 is in a tilted state after being deflected twice, the stamping die 109 needs to be corrected for subsequent stamping operations. Therefore, a reset rack 213 is fixedly installed on the stamping table 102. When the reset rack 213 is engaged with the external gear 206, it drives the stamping die 109 to reset and put the stamping die 109 in a horizontal state. Similarly, during implementation, the length of the reset rack 213 is set to half the length of the external rack 219.

[0043] In this embodiment: after the second protrusion 212 is deformed and breaks through the first protrusion 211, the driving rack 208 is engaged with the energy storage gear 205, and the energy storage gear 205 rotates while the mainspring 220 stores power, and the energy storage gear 205 is engaged with the outer rack 219, and the outer rack 219 is engaged with the outer gear 206. 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 performs wear detection on the edge position of the stamping die 109. In this process, the first pawl 214 and the first ratchet ring 216 are not engaged, so the rotation of the inner gear 207 and the rotation of the outer gear 206 will not conflict. When the driving rack 208 continues to move forward and no longer meshes with the energy storage gear 205, the mainspring 220 drives the energy storage gear 205 to rotate in the opposite direction. At this time, the inner rack 218 drives the inner gear 207 to rotate, and the No. 1 ratchet 214 engages with the No. 1 ratchet ring 216, thereby driving the stamping die 109 to deflect in the opposite direction and performing wear detection on the other edge of the stamping die 109. Compared with directly detecting the stamping die 109, the edge of the stamping die 109 is deflected outward, so that the laser detector 107 can better align with the edge position of the stamping die 109, and the edge positions of the stamping die 109 after two deflections overlap 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, thereby increasing the practicality of the device.

[0044] Embodiment 3: This embodiment is intended to promote the solution of the problem of rapid return and reset of the stamping die 109 after the detection is completed. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 to 13 The slide 400 includes an outward slide 401 and a return slide 402. The outward slide 401 is arranged in parallel with the return slide 402. The elevation of the tail end of the outward slide 401 is higher than the elevation of the head end, and the elevation of the return slide 402 gradually decreases. After the stamping is completed, the movable support 201 enters the return slide 402, and the movable support 201 drives the stamping die 109 to quickly reset.

[0045] It should be noted that, in this embodiment, after the stamping die 109 is inspected, the stamping die 109 can be quickly reset. However, according to the specific situation and the accuracy requirement of the stamping die 109, the inspection frequency of the stamping die 109 can be changed. Specifically, if the accuracy requirement of the stamping die 109 is high, the stamping die 109 is inspected once for every 5-10 stamping operations. Conversely, if the accuracy requirement of the stamping die 109 is low, the stamping die 109 is inspected once for every 70-100 stamping operations.

[0046] Among them, a slide groove 305 is opened on the electric slider 301, and a slider 307 is slidably installed in the slide groove 305. The vertical rod 202 is fixedly installed on the slider 307, and the vertical rod 202 slides in contact with the through groove 500. A baffle plate 302 is installed on the electric slider 301, and a No. 1 compression spring 304 is arranged on the baffle plate 302. The slider 307 is fixedly connected to one end of the No. 1 compression spring 304. A second sleeve 505 is installed at the bottom of the stamping table 102, and a No. 3 compression spring 507 is arranged in the second sleeve 505. A No. 2 wedge block 506 is slidably installed in the second sleeve 505, and one end of the No. 2 wedge block 506 is fixedly connected to the No. 3 compression spring 507. A No. 1 wedge block 306 is installed at one end of the slider 307, and the No. 1 wedge block 306 slides in contact with the No. 2 wedge block 506.

[0047] In addition, the through groove 500 includes an outward through groove 501, a first oblique through groove 502, a return through groove 503, and a second oblique through groove 504. The outward through groove 501, the first oblique through groove 502, the return through groove 503 and the second oblique through groove 504 are connected in sequence. Under the action of the No. 1 compression spring 304, the vertical rod 202 conflicts with the inner wall of the through groove 500. Therefore, the first oblique through groove 502 is provided to make it easier for the vertical rod 202 to enter the return through groove 503 from the outward through groove 501. Similarly, the first oblique through groove 502 makes it easier for the vertical rod 202 to enter the outward through groove 501 from the return through groove 503.

[0048] In this embodiment: after the stamping is completed, the movable support 201 drives the stamping die 109 to continue to move forward. When the vertical rod 202 moves to the tail end of the outward groove 501, the vertical rod 202 enters the first oblique groove 502 under the push of the No. 1 compression spring 304, and then the electric slider 301 moves in the opposite direction to bring the vertical rod 202 to the return groove 503, and the elevation of the return slide 402 gradually decreases, so as to facilitate the movable support 201 to quickly reset following the vertical rod 202. When the vertical rod 202 moves to the tail end of the return groove 503, the No. 1 wedge block 306 slides in contact with the No. 2 wedge block 506, so that the vertical rod 202 smoothly enters the second oblique groove 504, thereby achieving the purpose of resetting the vertical rod 202 and the movable support 201.
