[0045] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0046] like Figures 1-8 As shown, the present invention provides a servo stamping device, comprising:

[0047] The housing 1 contains a stamping station, a stamping mechanism 3, and a servo mechanism 2. The stamping station is located below the stamping mechanism 3 and the servo mechanism 2, and the servo mechanism 2 is connected to the stamping mechanism 3.

[0048] The working principle and beneficial effects of the above technical solution are as follows: Before the stamping begins, the upper and lower dies are quickly installed in the stamping station through the mounting positioning holes. Then, the part to be stamped is placed between the upper and lower dies in the stamping station. Then, the stamping mechanism 3 is driven by the servo mechanism 2 to perform stamping. The stamping is completed by replacing the hydraulic pressure with the servo mechanism 2, which avoids the large noise of the hydraulic stamping equipment and the inconvenience of maintenance due to oil stains. In addition, the servo mechanism 2 has a small structure, which makes the stamping equipment easy to move.

[0049] In one embodiment, the servo mechanism 2 includes:

[0050] Servo motor 7, wherein the servo motor 7 is disposed within the housing 1;

[0051] A first rotating rod 9, one end of which is connected to the servo motor 7, and the other end of which passes through the housing 1 and is connected to the first transmission wheel 10;

[0052] The second rotating rod 13 has one end connected to the stamping mechanism 3 and the other end passing through the housing 1 and connected to the second transmission wheel 12. The second transmission wheel 12 and the first transmission wheel 10 are connected by a belt 11.

[0053] The working principle and beneficial effects of the above technical solution are as follows: In actual use, the servo motor 7 is started, and the servo motor 7 drives the first rotating rod 9 to rotate. The first rotating rod 9 drives the second rotating wheel 12 to rotate through the first transmission wheel 10 and the belt 11. The second rotating wheel 12 drives the stamping mechanism 3 to complete the stamping through the second rotating rod 13. The servo motor 7 replaces the hydraulic pressure to complete the stamping.

[0054] In one embodiment, the stamping mechanism 3 includes:

[0055] Cam cavity 14, the cam cavity 14 is disposed in the housing 1, the cam cavity 14 is located on one side of the servo motor 7, and the second rotating rod 13 extends into the cam cavity 14;

[0056] Cam 15, which is sleeved in the cam cavity 14, is located in the cam cavity 14, and has a cam groove 16 on it;

[0057] Limiting hole 18, the limiting hole 18 is provided between the cam cavity 14 and the stamping station;

[0058] A connecting rod 8 is provided, one end of which is rotatably connected to the sliding wheel 19, the sliding wheel 19 being slidably connected to the cam groove 16, and the other end of the connecting rod 8 being connected to the top end of the stamping rod 17, the bottom end of the stamping rod 17 passing through the limiting hole 18, and the stamping rod 17 being slidably connected to the limiting hole 18.

[0059] The working principle and beneficial effects of the above technical solution are as follows: In actual use, the second rotating rod 13 drives the cam 15 to rotate. During the rotation, the cam 15 drives the stamping rod 17 to move up and down reciprocally through the sliding wheel 19, the connecting rod 8 and the limiting hole 18 to complete the stamping of the components on the stamping station.

[0060] In one embodiment, the stamping station includes:

[0061] The stamping groove 4 is provided inside the housing 1 and is located below the cam cavity 14. The bottom end of the stamping rod 17 extends into the stamping groove 4 and is connected to the top end of the upper mold 6.

[0062] The lower mold 5 is disposed on the inner wall of the stamping groove 4.

[0063] The working principle and beneficial effects of the above technical solution are as follows: The upper mold 6 is installed at the bottom of the stamping rod 17, and then the lower mold 5 is installed in the stamping groove 4. Then the workpiece is placed in and stamping begins.

[0064] In one embodiment, the profile of the cam groove 16 is the same as the profile of the cam 15.

[0065] The working principle and beneficial effects of the above technical solution: The contour of the cam groove 16 is the same as the contour of the cam 15, so that the cam 15 can drive the connecting rod to move up and down.

[0066] In one embodiment, a reducer 20 is provided between the servo motor 7 and the first rotating rod 9, the servo motor 7 is connected to the input end of the reducer 20, and the first rotating rod 9 is connected to the output end of the reducer 20.

[0067] The working principle and beneficial effects of the above technical solution:

[0068] In one embodiment, a cleaning device is provided on the inner wall of the stamping groove 4, the cleaning device comprising:

[0069] Cleaning groove 30, the cleaning groove 30 is provided on the inner wall of the stamping groove 4;

[0070] The ejection cavity 22 is located inside the housing 1. The ejection cavity 22 is located on the side of the cleaning groove 30 away from the stamping groove 4. A sliding plate 24 is slidably connected inside the ejection cavity 22. A first spring 27 is provided between the sliding plate 24 and the inner wall of the ejection cavity 22.

[0071] Cleaning motor 21 is disposed on the inner wall of the ejection cavity 22 and is electrically connected to the controller;

[0072] The third rotating rod 23 has one end connected to the cleaning motor 21 and the other end connected to the push cam 25, which is in contact with the sliding plate 24.

[0073] Two cleaners are symmetrically arranged on the sliding plate 24. The cleaners include:

[0074] Cleaning block 26, one end of which is connected to the sliding plate 24, and the other end of which extends into the cleaning groove 30. The cleaning block 26 is provided with a wheel groove 29, and a cleaning wheel 28 is rotatably provided on the inner wall of the wheel groove 29 via a rotating shaft 31.

[0075] The detectors include two detectors within the cleaning block 26, with two adjacent detectors symmetrically arranged on both sides of the wheel groove 29. Each detector comprises:

[0076] The detection groove 32 is located at the bottom of the cleaning block 26, and a pressure sensor 33 is provided in the detection groove 32. The pressure sensor 33 is electrically connected to the controller.

[0077] A detection rod 35, one end of which is slidably connected to the detection groove 32, and the other end of which is rotatably connected to a detection wheel 36. A second spring 34 is provided between the detection rod 35 and the pressure sensor 33.

[0078] An electric telescopic rod 40 is mounted on the detection rod 35. The bottom end of the electric telescopic rod 40 is provided with an imprint block 41. The electric telescopic rod 40 is electrically connected to the controller.

[0079] The working principle of the above technical solution is as follows: In actual use, after the stamping equipment has been used a certain number of times, the cleaning motor 21 is started. The cleaning motor 21 drives the ejection cam 25 to rotate through the third rotating rod 23. The ejection cam 25 drives the two cleaning blocks 26 to move in the compression direction of the first spring 27 through the sliding plate 24. This causes the cleaning blocks 26 to drive the cleaning wheel 28 to leave the cleaning groove 30 and enter the stamping groove 4. The cleaning wheel 28 rolls at the bottom of the upper mold 6 and the top of the lower mold 5 to clean the upper mold 6 and the lower mold 5. At the same time, during the cleaning process, the cleaning blocks 26 will drive the detection rod 35 to move together, causing the detection wheel 36 to move on the mold surface, thereby squeezing the second spring 34. This causes the pressure sensor 33 to detect a pressure value. When the pressure value detected by the pressure sensor 33 deviates from the preset value, the two detectors will activate the electric telescopic rod 40 to extend. The extension of the electric telescopic rod 40 will drive the imprint block 41 to move in the direction of extension of the second spring 34, thereby leaving a mark on the mold.

[0080] The beneficial effects of the above technical solution are as follows: Through the design of the above structure, the cleaning device cleans the surfaces of the upper and lower dies after the stamping equipment has been used a certain number of times. The cleaning wheel 28 adsorbs and removes debris and dust from the die surface, preventing debris and dust from affecting the processing accuracy of the stamping equipment and protecting the die. After the die is installed, the cleaning device is activated, causing two detectors on the cleaning block to detect the die. When the detectors just touch the die, two first pressure values ​​are recorded. When the detectors leave the die, two second pressure values ​​are recorded again. Then, the first pressure values ​​and second pressure values ​​are compared to see if they are within a preset comparison range. If they are not within the preset range, the comparison is performed. If the pressure value is within the preset range, it indicates that the mold is not installed horizontally. The mold can be quickly adjusted based on the recorded pressure value to avoid stamping failure due to an angle between the upper and lower molds caused by the mold not being installed horizontally. If the pressure values ​​are the same, the pressure value is used as the preset value. After a period of use, when the cleaning device cleans the mold, if the mold is deformed due to excessive pressure during the cleaning process, the pressure value detected by the pressure sensor 33 will deviate from the preset value when the detector passes through the deformed position. The marking block 41 will leave a mark on the mold, thereby reminding the staff that the mold is damaged and can be replaced in time. At the same time, it is convenient for the staff to repair the mold according to the mark and avoid insufficient processing accuracy in the future.

[0081] In one embodiment, a buffer device 42 is further provided on the inner wall of the stamping groove 4. The buffer device 42 is located between the lower die 5 and the stamping groove 4, and the buffer device 42 includes:

[0082] A pressure groove 48 is provided on the inner wall of the stamping groove 4. The pressure block 44 is slidably connected in the pressure groove 48. A pressure plate 43 is provided at the top of the pressure block 44. The pressure plate 43 is located at the bottom of the lower mold 5. A third spring 46 is provided between the pressure plate 43 and the inner wall of the stamping groove 4. The top of the pressure plate 43 is provided with a mounting positioning hole.

[0083] Air chamber 45, the air chamber 45 is disposed in the pressure block 44, and a piston block 47 is slidably connected in the air chamber 45;

[0084] A movable rod 49, one end of which is connected to the bottom end of the piston block 47, and the other end of which extends into the pressure groove 48. The movable rod 49 is slidably connected to the pressure block 44.

[0085] A first limiting block 59 is sleeved on the moving rod 49, and a fourth spring 51 is provided between the first limiting block 59 and the pressure block 44.

[0086] A limiting groove 55 is provided on the inner wall of the pressing groove 48. A second limiting block 57 is slidably connected in the limiting groove 55. A fifth spring 56 is provided between the second limiting block 57 and the inner wall of the limiting groove 55. A ramp is provided on one side of the first limiting block 59 and one side of the second limiting block 57. An insertion hole 58 is provided on the second limiting block 57.

[0087] Slot 53, the slot 53 is disposed on the inner wall of the limiting groove 55;

[0088] Insert rod 52, one end of which is connected to the bottom end of the pressure plate 43, and the other end of which extends into the slot 53 and is connected to the inclined block 54;

[0089] The first air tube 50 has one end passing through the piston block 47 and communicating with the air chamber 45, and the other end passing through the moving rod 49 and connecting to one end of the hose 60.

[0090] Impact groove 37 is provided at the bottom of the inner wall of the ejection cavity 22. Impact rod 39 is slidably connected in the impact groove 37. A sixth spring 38 is provided between the impact rod 39 and the inner wall of the impact groove 37.

[0091] The second air tube 61 has one end connected to the other end of the hose 60, and the second air tube 61 passes through the housing 1 and communicates with the impact groove 37.

[0092] The working principle of the above technical solution is as follows: In actual use, when installing the upper and lower molds, the upper and lower molds are stacked, and then the pressure plate 43 is placed at the corresponding position. Then, straight rods are inserted into the mounting positioning holes around the upper and lower molds, and the upper mold is moved upward along the straight rods to complete the installation of the upper mold. After the lower mold 5 is installed on the pressure plate 43, the stamping equipment is started for stamping. During the stamping process, the upper mold 6 continuously applies pressure to the pressure plate 43 through the lower mold 5, causing the pressure plate 43 to move downward continuously. During the downward movement, the pressure plate 43 drives the pressure block 44 to move downward, so that the gas in the air chamber 45 enters the hose 60 through the first air pipe 50, and then enters the second air pipe 691. Inside the impact groove 37, the gas pushes the impact rod 39 to move in the extension direction of the sixth spring 38, causing the impact rod 39 to strike the sliding plate 24, which in turn causes the sliding plate 24 to vibrate, causing the cleaning wheel 28 on the cleaning block 26 to vibrate, thereby shaking off the dust and debris on the surface of the cleaning wheel 27. At the same time, as the pressure block moves down, the pressure on the lower mold increases with the compression of the third spring 46 and the fourth spring 51. When the pressure on the lower mold exceeds the preset value, the pressure plate 43 pushes the second limiting block 57 into the limiting groove 55 through the insert rod 52 and the inclined block 54, causing the second limiting block 57 to lose its point of force, thus greatly reducing the pressure on the lower mold 5.

[0093] The beneficial effects of the above technical solution are as follows: Through the design of the above structure, the buffer device 42 continuously impacts the sliding plate 24 through the impact rod 39 during the stamping process of the stamping equipment, causing the cleaning device to vibrate and shake off the debris on the surface of the cleaning wheel 28, thereby improving the cleaning effect of the cleaning wheel 28; at the same time, the buffer device buffers the lower mold 5 during the stamping process of the stamping equipment, and automatically deflects most of the force when the pressure value exceeds the preset value, so as to avoid the lower mold 5 being damaged by excessive pressure.

[0094] In one embodiment, the first drive wheel is equipped with a speed sensor, a pressure sensor, and a timer, and the housing 1 is equipped with an alarm. The speed sensor, pressure sensor, timer, and alarm are all electrically connected to the controller. The wear index of the belt is detected by the speed sensor, pressure sensor, timer, and alarm. The steps are as follows:

[0095] Step 1: The controller obtains the belt wear index based on the temperature sensor, timer, and formula:

[0096]

[0097] Where B is the belt wear index, v is the rotational speed of the first drive wheel detected by the speed sensor, μ is the friction coefficient between the first drive wheel and the belt, t is the rotational time of the first drive wheel recorded by the timer, r is the diameter of the first drive wheel, F0 is the preload between the first drive wheel and the belt, F is the pressure between the first drive wheel and the belt 11 detected by the pressure sensor, d is the length of the belt, and ln is the natural logarithm with base e.

[0098] Step 2: Compare the belt wear index obtained in Step 1 with the preset value. When the belt wear index is greater than the preset value, the controller will control the alarm to issue an alarm prompt; otherwise, the alarm will not work.

[0099] The working principle and beneficial effects of the above scheme are as follows: When the equipment operates for a long time, the belt will continuously wear down, meaning the belt wear index gradually increases with the increase of belt usage time. When the pressure between the belt and the first drive pulley decreases, the relative movement between the belt and the first drive pulley increases, accelerating the increase of the belt wear index. An increased belt wear index leads to a decline in equipment performance and affects normal operation. By detecting the rotational speed of the first drive pulley, the pressure between the first drive pulley and the belt, and recording the rotation duration of the first drive pulley by a timer, the belt wear index is calculated. The calculated belt wear index is compared with a preset value. When the belt wear index exceeds the preset value, the controller activates the alarm to issue an alarm; otherwise, the alarm does not activate. Users can promptly perform maintenance based on the alarm. This system monitors the belt wear index, improves automation through automatic alarms, facilitates timely maintenance, optimizes the system experience, and increases the intelligence of the equipment.

[0100] In one embodiment, the cleaning wheel 28 is made of sponge.

[0101] The working principle and beneficial effects of the above technical solution: The cleaning wheel 28 made of sponge can effectively absorb debris and dust on the mold.

[0102] In one embodiment, the piston block 47 is made of rubber material.

[0103] The working principle and beneficial effects of the above technical solution: Rubber has good sealing performance, which can improve the impact effect of the impact rod 39.

After the stamping equipment has been used a certain number of times, the cleaning motor (21) is started. The cleaning motor (21) drives the push cam (25) to rotate through the third rotating rod (23), so that the push cam (25) drives the two cleaning blocks (26) to move in the compression direction of the first spring (27) through the sliding plate (24). This causes the cleaning blocks (26) to drive the cleaning wheel (28) to leave the cleaning groove (30) and enter the stamping groove (4), so that the cleaning wheel (28) rolls at the bottom of the upper mold (6) and the top of the lower mold (5), which is the upper mold (6) and the bottom of the lower mold (5). The lower mold (5) is cleaned; at the same time, during the cleaning process, the cleaning block (26) will drive the detection rod (35) to move together, so that the detection wheel (36) moves on the surface of the mold, thereby squeezing the second spring (34), so that the pressure sensor (33) detects a pressure value. When the pressure value detected by the pressure sensor (33) deviates from the preset value, the electric telescopic rod (40) will be activated to extend. The extension of the electric telescopic rod (40) will drive the printing block (41) to move in the direction of the extension of the second spring (34), thereby leaving a mark on the mold.
