[0014] A method for stamping automobile parts, comprising step 1, preparing raw materials; step 2, installing molds; step 3, stamping and forming; step 4, vibration monitoring; step 5, separating and taking materials; step 6, quality inspection;

[0015] In the above step 1, raw materials with no surface defects such as rust, inclusions, cracks, etc. and meeting the material requirements of product design are prepared, and the plates are cut into appropriate sizes according to the production plan;

[0016] In the above step 2, the corresponding mold is installed according to the production plan;

[0017] In the above step 3, the equipment is started to perform stamping and forming processing of automobile parts;

[0018] In the above step 4, vibration monitoring is performed by a beam sensor during the stamping process;

[0019] In the above step 5, the material is automatically unloaded through the unloading assembly;

[0020] In the above step six, the surface quality of the finished product is inspected by the inspection component.

[0021] As a further technical solution of the present invention, in the step four, vibration monitoring is performed during the stamping process by a signal transmitter on the die and a corresponding signal receiver on the punch. The light signal emitted by the signal transmitter passes through the mold gap to reach the signal receiver. When the mold vibrates, the propagation characteristics of the light signal will change, such as offset, scattering or attenuation. The signal receiver converts the received signal into an electrical signal and records it through a data acquisition system. The vibration signal is then processed and analyzed using data analysis software to extract key parameters such as amplitude, frequency, and phase. Based on the analysis results, the degree and impact range of the mold vibration are evaluated. If it is found that the vibration exceeds the allowable range or abnormal phenomena occur, the process parameters should be adjusted in time or other measures should be taken to reduce the impact of vibration on product quality. At the same time, the vibration monitoring results also provide feedback information for mold design and manufacturing, helping to improve the mold structure and improve production stability.

[0022] As a further technical solution of the present invention, in the step five, after the stamping is completed, the die and the punch are separated, and the hydraulic cylinder pushes the first ejector column upward along the first through hole and the second through hole through the push plate, and ejects the ejector column from the third through hole, so that the workpiece attached to the die is detached, and then the first motor on the fixed plate is started, and the sliding seat is driven to move along the second guide rail through the first screw rod, thereby driving the connecting frame to extend in, and then the downward pressure cylinder drives the first slider to be pressed down along the third guide rail, and the connecting frame is pressed down synchronously, and the workpiece is adsorbed by the suction head, and the downward pressure cylinder is reset. At the same time, the first motor drives the sliding seat to reset and take out the workpiece, and then the second motor in the mounting seat is started, driving the connecting frame to rotate 180 degrees, and the workpiece is placed on the conveyor belt to complete automatic material removal.

[0023] As a further technical solution of the present invention, in step six, the conveyor belt on the third base transports the workpiece through the bottom of the bracket, and the camera on the second slider takes pictures and performs inspections to detect surface defects such as cracking, necking, hole deformation, etc. The online inspection records of the stamped products are added to the database to prevent defective products from flowing out.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] First, the present invention designs a first limiting slider that is slidably connected to the limiting groove, ensuring the stable installation and positioning of the lower die seat on the first base, thereby improving the overall stability of the mold. The positioning fixture is fixed by fastening bolts to fix the lower die seat. This design facilitates the installation and adjustment of the mold and improves the flexibility and maintainability of the mold.

[0026] Second, the present invention uses a hydraulic cylinder to push the ejector column through a push plate to eject the workpiece from the die. This mechanized ejection method improves the stamping efficiency, while ensuring the accurate separation of the workpiece and avoiding the error of manual material removal. Automated material removal is achieved through the unloading assembly, including the first motor driving the sliding seat to move, the down-pressing cylinder driving the down-pressing connecting frame to absorb the workpiece, and the second motor rotating the connecting frame to place the workpiece on the conveyor belt. This series of automated operations greatly improves production efficiency and reduces labor costs.

[0027] Third, the present invention is designed with a visual inspection mechanism for stamped finished products. The inspection component uses a camera to take pictures of the workpieces on the conveyor belt and adds the inspection records to the database, ensuring the timely discovery and processing of defective products and preventing defective products from flowing out of the market.

[0028] Fourth, the present invention provides safety protection in the production process through the safety grating installed on the fixed seat, preventing people from mistakenly entering the dangerous area; at the same time, the display screen is used to set and monitor parameters such as the stamping stroke, which improves the convenience of operation and the safety of production. The vibration of the mold is monitored by the signal transmitter and the signal receiver, and the impact of vibration on product quality is evaluated by data analysis software. The process parameters are adjusted in time, which not only improves the overall quality of the product, but also enhances the stability and controllability of the production process.

[0048] Please see attached Fig. 9 The present invention provides an embodiment: a method for stamping automobile parts, comprising step 1, preparing raw materials; step 2, installing molds; step 3, stamping; step 4, vibration monitoring; step 5, separating and taking materials; step 6, quality inspection;

[0049] In the above step 1, raw materials with no surface defects such as rust, inclusions, cracks, etc. and meeting the material requirements of product design are prepared, and the plates are cut into appropriate sizes according to the production plan;

[0050] In the above step 2, the corresponding mold is installed according to the production plan;

[0051] In the above step 3, the equipment is started to perform stamping and forming processing of automobile parts;

[0052] In the above step 4, vibration monitoring is performed during the stamping process by a beam sensor, which is a sensor that works in combination with a transmitter and a receiver. In this application, the signal transmitter emits light (such as infrared, laser, etc.), and the light is received by the corresponding signal receiver after passing through a certain spatial distance. When the path between the two is blocked by an object or the light is disturbed during the propagation process (such as light deviation, scattering, etc. caused by mold vibration), the signal received by the receiver will change. After this change is converted into an electrical signal, it can be used to detect the existence, position or state of the object, and monitor the vibration of the mechanical equipment. The beam sensor of the present invention includes a signal transmitter 115, which is used to emit a light signal (such as infrared, laser, etc.), and the signal transmitter is installed on the upper surface of the die 111. The signal receiver 122 is used to receive the light signal emitted from the signal transmitter, and the signal receiver is installed on the punch 120 to form a beam relationship with the signal transmitter. The signal processing circuit is inside the beam sensor, and is used to convert the received light signal into an electrical signal, and perform preliminary amplification, filtering and other processing.

[0053] The light signal emitted by the signal transmitter 115 passes through the mold gap to reach the signal receiver 122. When the mold vibrates, the propagation characteristics of the light signal will change, such as offset, scattering or attenuation. The signal receiver 122 converts the received signal into an electrical signal and records it through the data acquisition system. The vibration signal is then processed and analyzed using data analysis software to extract key parameters such as amplitude, frequency, and phase. Based on the analysis results, the degree and impact range of mold vibration are evaluated. If it is found that the vibration exceeds the allowable range or an abnormal phenomenon occurs, the process parameters should be adjusted in time or other measures should be taken to reduce the impact of vibration on product quality. At the same time, the vibration monitoring results also provide feedback information for mold design and manufacturing, helping to improve the mold structure and improve production stability;

[0054] Among them, in the above step five, after the stamping forming is completed, the die 111 and the punch 120 are separated, and the hydraulic cylinder 12 pushes the first ejector column 14 through the push plate 13 to eject upward along the first through hole 15 and the second through hole 110, and ejects the ejector column 17 from the third through hole 113, so that the workpiece attached to the die 111 is detached, and then the first motor 23 on the fixed plate 21 is started, and the sliding seat 25 is driven to move along the second guide rail 22 through the first screw rod 24, thereby driving the connecting frame 211 to extend in, and then the pressing cylinder 26 drives the first slider 28 to press down along the third guide rail 27, and the connecting frame 211 is pressed down synchronously, and the workpiece is adsorbed by the suction head 212, and the pressing cylinder 26 is reset. At the same time, the first motor 23 drives the sliding seat 25 to reset and take out the workpiece, and then the second motor 210 in the mounting seat 29 is started, driving the connecting frame 211 to rotate 180 degrees, and the workpiece is placed on the conveyor belt 32, completing the automatic material removal.

[0055] In the above step six, the surface quality of the finished product is inspected by the inspection component 3, the conveyor belt 32 on the third base 31 transports the workpiece through the bottom of the bracket 33, and the camera 38 on the second slider 37 takes pictures and performs inspections to detect surface defects such as cracking, necking, hole deformation, etc. The online inspection records of the stamped finished products are added to the database to avoid the outflow of defective products.

[0056] When using the present invention, first prepare raw materials with no defects such as rust, inclusions, cracks, etc. on the surface and meeting the material requirements of the product design, cut the plates into appropriate sizes according to the production plan, then install the corresponding molds according to the production plan, perform stamping processing through the stamping assembly 1, install the lower die base 16 on the first base 11 through the first limiting slider 19 and the limiting groove 18, ensure that the second through hole 110 is aligned with the first through hole 15, then adjust the positioning fixture 128 to fix the position of the lower die base 16 through the second limiting slider 129, and tighten it through the fastening bolts 130, install the die 111 on the lower die base 16, and install the punch 120 on the upper die base 119 through the fixing bolts 121. After the installation is completed, set the parameters such as the stamping stroke through the display screen 127 on the second base 126, and perform a preview and debugging to detect whether the safety grating 112 is working normally.

[0057] After the preparation work is completed, the automobile parts are stamped. The raw material is placed on the die 111 and positioned by the positioning pin 114. The hydraulic station 124 drives the upper die seat 119 to press down along the first guide rail 118 on the fixed seat 117 through the second top column 125. The die 111 and the punch 120 cooperate to stamp the raw material. During the stamping process, vibration monitoring is performed through the signal transmitter 115 on the die 111 and the corresponding signal receiver 122 on the punch 120. The light signal emitted by the signal transmitter 115 passes through the mold gap to reach the signal receiver 122. When the mold vibrates, the propagation of the light signal The characteristics will change, such as offset, scattering or attenuation. The signal receiver 122 converts the received signal into an electrical signal and records it through the data acquisition system. The vibration signal is then processed and analyzed using data analysis software to extract key parameters such as amplitude, frequency, and phase. Based on the analysis results, the degree and impact range of the mold vibration are evaluated. If it is found that the vibration exceeds the allowable range or abnormal phenomena occur, the process parameters should be adjusted in time or other measures should be taken to reduce the impact of vibration on product quality. At the same time, the vibration monitoring results also provide feedback information for mold design and manufacturing, helping to improve the mold structure and improve production stability.

At the same time, the first motor 23 drives the sliding seat 25 to reset and take out the workpiece, and then the second motor 210 in the mounting seat 29 is started, driving the connecting frame 211 to rotate 180 degrees, and the workpiece is placed on the conveyor belt 32, completing the automatic material removal.

[0059] Then, the surface quality of the finished product is inspected through the inspection component 3. The conveyor belt 32 on the third base 31 transports the workpiece through the bottom of the bracket 33. The camera 38 on the second slider 37 takes pictures and performs inspections to detect surface defects such as cracking, necking, hole deformation, etc. The online inspection records of the stamped products are added to the database to avoid the outflow of defective products. Depending on the different processed parts, the second screw rod 36 is driven by the third motor 34 to drive the second slider 37 to move along the fourth guide rail 35 to adjust the position of the camera 38, wherein the first support column 116 and the second support column 123 are used to support the fixed seat 117 and the hydraulic station 124.
