[0002] In the process of stamping spring riveting base, since the riveting base itself is relatively thin and the curvatures of the parts are different, in the demolding process, the places with relatively large curvatures have concentrated contact stress and large friction, if the demolding agent is insufficient or unevenly distributed, the problems of die sticking, riveting base tearing and even deformation are prone to occur. Therefore, the curvature of the lower die of the riveting base needs to be scanned and recognized, and the demolding agent is sprayed adaptively according to the detected curvature, so as to realize the simultaneous and uniform demolding of each point of the riveting base, prevent tearing and even deformation. At the same time, in the traditional stamping process, manual feeding is often needed, which is time-consuming and labor-consuming, and the stamping efficiency is low, which cannot meet the working requirements of high efficiency and high quality.

[0006] Further, the two ends of the workbench are provided with conveying guide rollers.

[0007] The conveying guide rollers at the two ends of the workbench are responsible for righting the stamping piece and lifting the stamping piece to the height of the upper end face of the lower die, so as to prevent the height difference from being too large and affecting the overall conveying of the stamping piece.

[0008] Further, the stamping module comprises a stamping support and a hydraulic cylinder, the stamping support is arranged on the workbench, the stamping support and the workbench are fixedly connected, the stamping support is located between the conveying guide rollers at the two ends of the workbench, the hydraulic cylinder and the stamping support are fixedly connected, the output end of the hydraulic cylinder penetrates through the lower end of the stamping support, the output end of the hydraulic cylinder and the upper die are fixedly connected, and one end of the linkage module is hinged to the output end of the hydraulic cylinder.

[0009] The stamping support is arranged on the workbench and is used for fixed installation of the hydraulic cylinder. The up-down movement of the upper die is realized through the extension and retraction of the output end of the hydraulic cylinder, so that the stamping of the stamping piece is completed. At the same time, during the stamping process, the output end of the hydraulic cylinder is retracted and extended through the transmission of the linkage module, so that the synchronous movement of the pressure feeding module is driven, the accurate positioning of the stamping piece and the lower die is ensured, and the accuracy and efficiency of stamping are improved.

[0011] The vertical fixed rod, the connecting rod and the crank block constitute a linkage mechanism like a crank slider, wherein the output end of the hydraulic cylinder drives the vertical fixed rod to move vertically, drives the crank block to rotate around the fixed axis through the transmission of the connecting rod, and drives the pressure sending module to work when the crank block rotates, so as to realize the synchronous operation of the stamping module and the pressure sending module, effectively improve the automation degree of the stamping device, ensure the accurate positioning of the stamping part in the stamping process, and effectively improve the stamping efficiency and product quality.

[0012] Further, the pressure sending module comprises a reset spring base, a pressure sending support plate, a lower pressure sending unit, an upper pressure sending unit and an adaptive unit. The reset spring base is arranged on the workbench and is fixedly connected to the bottom end of the workbench. The pressure sending support plate is arranged on the reset spring base and is fixedly connected to the upper end of the reset spring base. The two ends of the lower pressure sending unit are rotatably connected to the pressure sending support plate. The two ends of the upper pressure sending unit are rotatably connected to the pressure sending support plate. The adaptive unit is fixedly connected to the upper pressure sending unit and is arranged in multiple on the upper pressure sending unit. The lower pressure sending unit is located below the adaptive unit.

[0013] The adaptive units on the lower pressure sending unit and the upper pressure sending unit are used for positioning and clamping the stamping part. The adaptive units can be adaptively adjusted according to the thickness of the edge of the stamping part during clamping, so as to change the clamping force on the edge of the stamping part and ensure the stable clamping of the stamping part during stamping. When the stamping device is working, the output end of the hydraulic cylinder is continuously elongated until the connecting rod is vertical, the crank block is located at the lower dead point, the reset spring base is compressed, the pressure sending support plate is sunken, the lower pressure sending unit, the upper pressure sending unit and the adaptive unit are collectively lowered, the stamping part falls into the lower die, and the upper die and the lower die are combined. After stamping is completed, the output end of the hydraulic cylinder is retracted, the lower pressure sending unit and the upper pressure sending unit apply an external force to the crank block to drive the crank block to rotate and move away from the lower dead point position. When the connecting rod is vertical again, the crank block is located at the upper dead point, the rebound speed of the reset spring base is slower than the retraction speed of the output end of the hydraulic cylinder, the output end of the hydraulic cylinder pulls the pressure sending support plate back to the original position, the lower pressure sending unit and the upper pressure sending unit apply an external force to the crank block to drive the crank block to rotate and move away from the upper dead point position.

[0014] Further, the lower pressure sending unit comprises two lower rollers, two lower conveying belts and a lower torsion motor. The two lower rollers are arranged at the two ends of the two lower conveying belts, the two lower conveying belts are sleeved on the two lower rollers at the two ends, the two lower rollers and the two lower conveying belts form a rectangle, the lower die is located in the rectangle, the lower torsion motor is fixedly connected to the pressure sending support plate, the two ends of the two lower rollers are respectively fixedly connected to one crank block, the output end of the lower torsion motor is fixedly connected to one end of one lower roller, and the crank block on the same side of the lower torsion motor is located between the lower torsion motor and the one end of the lower roller.

[0015] The rotation axis of the lower roller coincides with the fixed axis of the crank block. When the hydraulic cylinder works, the lower roller is driven to rotate through the transmission of the vertical fixed rod, the connecting rod and the crank block, and the vertical movement of the hydraulic cylinder is converted into the horizontal movement of the lower conveying belt. The lower conveying belt cooperates with the upper pressing and conveying unit and the self-adaptive unit to clamp and convey the stamping part, ensures the fixed pressing and conveying distance of the stamping part in one stamping process, and realizes the accurate positioning of the stamping part and the lower die. When the crank block needs to be separated from the upper dead point or the lower dead point position, the lower torsion motor drives the lower roller to rotate, and then drives the crank block to rotate, so as to separate from the upper dead point or the lower dead point, and prevent the device from being stuck.

[0016] Further, the upper pressing and conveying unit comprises two upper rollers, two upper conveying belts and an upper torsion motor. The two upper rollers are arranged at the two ends of the two upper conveying belts, the two upper conveying belts are sleeved on the two upper rollers at the two ends, the two upper rollers and the two upper conveying belts form a rectangle, the lower die is located in the rectangle, the upper torsion motor is fixedly connected with the pressing and conveying support plate, the two ends of the two upper rollers are respectively fixedly connected with a crank block, the output end of the upper torsion motor is fixedly connected with one end of one upper roller, and the crank block on the same side of the upper torsion motor is located between the upper torsion motor and the one end of the upper roller.

[0017] The rotation axis of the upper roller coincides with the fixed axis of the crank block. When the hydraulic cylinder works, the upper roller is driven to rotate through the transmission of the vertical fixed rod, the connecting rod and the crank block, and the vertical movement of the hydraulic cylinder is converted into the horizontal movement of the upper conveying belt. The upper conveying belt cooperates with the lower conveying belt and the self-adaptive unit to clamp and convey the stamping part, ensures the fixed pressing and conveying distance of the stamping part in one stamping process, and realizes the accurate positioning of the stamping part and the lower die. When the crank block needs to be separated from the upper dead point or the lower dead point position, the upper torsion motor drives the upper roller to rotate, and then drives the crank block to rotate, so as to separate from the upper dead point or the lower dead point, and prevent the device from being stuck. At the same time, the directions of the upper torsion motor and the lower torsion motor are opposite when rotating. Under the action of the upper torsion motor, the crank block connected with the upper pressing and conveying unit rotates counterclockwise towards the discharging direction of the stamping device, and under the action of the lower torsion motor, the crank block connected with the lower pressing and conveying unit rotates clockwise towards the discharging direction of the stamping device. Then, under the driving of the crank blocks with different directions, the rotating directions of the lower conveying belt and the upper conveying belt are also opposite, and the stamping parts between the lower conveying belt and the upper conveying belt are subjected to the same direction of the friction force applied to the surfaces of the two surfaces, so as to realize the pressing and conveying of the stamping parts.

[0019] The adaptive cylinder can adaptively adjust the thickness of the edge of the stamping part according to the pressure data fed back by the pressure sensor. When the adaptive cylinder starts to cooperate with the lower conveying belt to clamp the stamping part, the output end of the adaptive cylinder is elongated, the pressing plate and the pressure sensor contact the stamping part, and as the output end of the adaptive cylinder is continuously elongated, the pressure borne by the pressure sensor is continuously increased, and when the pressure increases to a preset value, the adaptive cylinder stops elongating, so that no matter the thickness of the edge of the stamping part, a stable clamping force is maintained, the clamping force is prevented from being insufficient, the stamping part is prevented from being displaced when the stamping device stamps, and the stamping precision is affected, and the clamping force is prevented from being too large to cause damage to the stamping part.

[0020] Further, the release agent adaptive spraying module comprises a telescopic rotary motor, a micro cylinder, a release agent spray head and a laser contour sensor, the output end of the telescopic rotary motor is telescopic and rotatable, the telescopic rotary motor is fixedly connected with the workbench, the telescopic rotary motor is located below the lower mold, the output end of the telescopic rotary motor is inserted into the lower mold, two micro cylinders are arranged on the top end of the output end of the telescopic rotary motor, the two micro cylinders and the top end of the output end of the telescopic rotary motor are fixedly connected, the release agent spray head is fixedly connected with the output end of one micro cylinder, and the laser contour sensor is fixedly connected with the output end of the other micro cylinder.

[0021] The telescopic rotary motor drives the output end to be telescopic, and the height of the micro pneumatic cylinder, the releasing agent nozzle and the laser profile sensor is adjusted. When the releasing agent needs to be sprayed on the lower mold, the output end of the telescopic rotary motor is extended, the laser profile sensor is located above the lower mold, the output end of the telescopic rotary motor is rotated, the micro pneumatic cylinder pushes the laser profile sensor to a preset position, the laser profile sensor is started, the shape and size of the lower mold are accurately scanned, and the profile data of the surface of the lower mold is acquired. According to the profile data acquired through scanning, the control system automatically calculates the optimal spraying position and spraying amount of the releasing agent. Then the micro pneumatic cylinder pushes the releasing agent nozzle to move to the preset spraying position, so that the uniformity and accuracy of spraying are ensured, the contact surface of the stamping part can be uniformly separated from the lower mold when the stamping part is separated from the lower mold, and the stamping part is prevented from being damaged or broken. After spraying is completed, the micro pneumatic cylinder pulls back the releasing agent nozzle and the laser profile sensor, the output end of the telescopic rotary motor stops rotating and starts retracting, the micro pneumatic cylinder, the releasing agent nozzle and the laser profile sensor are retracted into the lower mold, and interference with subsequent stamping is prevented.

The plane of the pressure sensor 413 away from the adaptive cylinder 412 coincides with the plane of the pressing plate 414 away from the adaptive cylinder 412.

[0041] The adaptive cylinder 412 can adaptively adjust the thickness of the edge of the stamping part according to the pressure data fed back by the pressure sensor 413. When the adaptive cylinder 412 starts to cooperate with the lower conveying belt 47 to clamp the stamping part, the output end of the adaptive cylinder 412 is elongated, the pressing plate 414 and the pressure sensor 413 contact the stamping part, and as the output end of the adaptive cylinder 412 is continuously elongated, the pressure on the pressure sensor 413 is continuously increased. When the pressure increases to a preset value, the adaptive cylinder 412 stops elongating, so that no matter the thickness of the edge of the stamping part, a stable clamping force is maintained to prevent insufficient clamping force, displacement of the stamping part when the stamping device is stamping, and influence on the stamping precision, and also prevent excessive clamping force from damaging the stamping part.

[0042] As shown in Figure 5 and Figure 9 The release agent adaptive spraying module 6 comprises a telescopic rotary motor 61, a micro pneumatic cylinder 62, a release agent spray head 63, and a laser contour sensor 64. The output end of the telescopic rotary motor 61 is telescopic and rotatable. The telescopic rotary motor 61 is fixedly connected to the workbench 1. The telescopic rotary motor 61 is located below the lower mold 52. The output end of the telescopic rotary motor 61 is inserted into the lower mold 52. Two micro pneumatic cylinders 62 are arranged on both sides of the top end of the output end of the telescopic rotary motor 61. The two micro pneumatic cylinders 62 are fixedly connected to the top end of the output end of the telescopic rotary motor 61. The release agent spray head 63 is fixedly connected to the output end of one micro pneumatic cylinder 62. The laser contour sensor 64 is fixedly connected to the output end of the other micro pneumatic cylinder 62.

[0043] The telescopic rotary motor 61 drives its output end to be telescopic, and the height of the micro pneumatic cylinder 62, the release agent nozzle 63 and the laser profile sensor 64 is adjusted. When the lower mold 52 needs to be sprayed with release agent, the output end of the telescopic rotary motor 61 is extended, the laser profile sensor 64 is located above the lower mold 52, the output end of the telescopic rotary motor 61 is rotated, the micro pneumatic cylinder 62 pushes the laser profile sensor 64 to a preset position, the laser profile sensor 64 is started, the shape and size of the lower mold 52 are accurately scanned, and the profile data of the surface of the lower mold 52 is obtained. According to the profile data obtained by scanning, the control system automatically calculates the best spraying position and spraying amount of the release agent. Then the micro pneumatic cylinder 62 pushes the release agent nozzle 63 to move to the preset spraying position, ensures the uniformity and accuracy of spraying, and makes the contact surface of the stamping part and the lower mold 52 uniformly separate when the stamping part separates from the lower mold 52, so as to prevent the stamping part from being pulled and broken. After spraying is completed, the micro pneumatic cylinder 62 pulls back the release agent nozzle 63 and the laser profile sensor 64, the output end of the telescopic rotary motor 61 stops rotating and starts retracting, the micro pneumatic cylinder 62, the release agent nozzle 63 and the laser profile sensor 64 are retracted into the lower mold 52, and interference with subsequent stamping is prevented.
