[0014] Preferably, a working method of a stamping die for automobile parts that can meet multi-process production comprises the following steps: Step 1: Install three different sets of dies for drawing, cutting and shaping in the three sets of positioning die grooves on the long edge surfaces of the first hexagonal turntable and the second hexagonal turntable respectively. The lower die plate and the upper die plate of the die are fixed by magnetic attraction to the positioning die grooves by the permanent magnetic plate on the bottom surface; Step 2: driving the stepper motor to operate, and under the transmission action of the transmission belt, driving the first hexagonal turntable and the second hexagonal turntable to rotate, so that the drawing dies on the first hexagonal turntable and the second hexagonal turntable face upward and downward respectively; Step 3: The second hydraulic rod is driven to extend the shock-absorbing strut at the output end and press against the stress-bearing edge strip on the short edge surface of the second hexagonal turntable; Step 4: The multi-axis robot arm absorbs the material at the end of the feeding conveyor through the vacuum suction plate on one side of the output end, and places it on the lower drawing template of the first hexagonal turntable. After completion, the robot arm withdraws, and the hydraulic cylinder, hydraulic telescopic column and first hydraulic rod drive. The hydraulic cylinder contracts to drive the upper drawing template under the second hexagonal turntable to move downward, and the first hydraulic rod drives the lower template on the first hexagonal turntable to move upward. During the process, the multi-section output end of the hydraulic telescopic column output end extends out and presses against the stress-bearing edge strip of the short edge surface of the first hexagonal turntable to provide hard support to the bottom to disperse the pressure. The upper template and the lower template are pressed together under the action of the hydraulic pressure to perform preliminary stamping and forming on the material. During the pressing process, the connecting seats on both sides of the first hexagonal turntable and the shock-absorbing struts at the upper end can use the first shock-absorbing spring and the second shock-absorbing spring to achieve buffering, and rely on the damping rod inside the spring to achieve shock absorption, effectively controlling the punching force; Step 5: After the material is stretched, the hydraulic cylinder, the hydraulic telescopic column, and the first and second hydraulic rods are reset, and the multi-axis robotic arm takes the material out through the vacuum suction plate on one side of the output end, and then the stepper motor drives the first hexagonal turntable and the second hexagonal turntable to rotate, so that the knife-breaking molds on the first hexagonal turntable and the second hexagonal turntable face upward and downward respectively. After completion, the first hydraulic rod and the second hydraulic rod are re-extended, and the loading robotic arm places the material on the lower template of the knife-breaking mold; Step 6: The hydraulic cylinder, hydraulic telescopic column and first hydraulic rod drive the upper template and the lower template to press together, and perform secondary cutting punching on the material. After completion, the hydraulic cylinder, hydraulic telescopic column and the first hydraulic rod and the second hydraulic rod are reset, and the multi-axis mechanical arm continues to take out the material to standby position, while the waste collection mechanical arm located at the rear of the device sorts out the waste formed by the cutting and trimming, and stores it in the waste collection box; Step 7: The stepper motor is driven again to drive the first hexagonal turntable and the second hexagonal turntable to rotate, so that the shaping molds on the first hexagonal turntable and the second hexagonal turntable face upward and downward respectively. After completion, the first hydraulic rod and the second hydraulic rod extend out, and the material is placed on the shaping lower template by the loading robot arm. During the process, the external cooling fan cooperates with the high-pressure air pump to connect the pipe joint on the nozzle rack, and the cold air is sprayed from the multiple blowing heads in front of the nozzle rack to spray and cool down the drawing molds on the first hexagonal turntable and the second hexagonal turntable that rotate to the direction of the blowing head for dust removal, so that they can be used for the next stamping. The cooling fans located at the ends of the first hexagonal turntable and the second hexagonal turntable introduce external air into the inner cavity of the first hexagonal turntable and the second hexagonal turntable, and cooperate with the multiple groups of fins at the bottom of the positioning die groove to discharge the heat from the heat dissipation groove; Step 8: The hydraulic cylinder, hydraulic telescopic column and the first hydraulic rod drive the upper template and the lower template to press together to shape and stamp the material. After completion, the hydraulic cylinder, hydraulic telescopic column and the first and second hydraulic rods are reset, and the laser scanner on the other side of the multi-axis robot arm scans the stamped material. During the scanning, the laser light source emits structured light and projects the structured light pattern onto the device under test. At the same time, the CCD cameras on both sides use the parallax principle to capture the depth information of the molded material and construct a three-dimensional model of the molded material. After uploading the model through the terminal, the algorithm and the defect-free data in the database are compared. The molding material model is compared. If the difference between the two sets of models is less than the threshold after comparison, it is judged that the molding material has no defects. At this time, the output end of the multi-axis robot arm is switched to the vacuum suction plate on the other side to take out the material. After completion, the stepper motor runs again and switches to the drawing mold after cooling and dust removal. At this time, the blowing mechanism continues to run to cool and dust the broken knife mold. This cycle is repeated to achieve continuous automated production. If the difference between the two sets of models is greater than the threshold after comparison, it is judged that the molding material has obvious defects. At this time, the terminal feedbacks a signal to the alarm module to remind personnel to come to inspect and maintain the mold to reduce production losses.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention installs three sets of different molds for drawing, knife breaking and shaping in three groups of positioning mold grooves on the long edge surfaces of the first hexagonal turntable and the second hexagonal turntable respectively. During stamping, the first hexagonal turntable and the second hexagonal turntable can be driven to rotate through the output end of the stepper motor and the transmission action of the transmission belt to adjust the orientation of different molds on the outer wall, so as to achieve the effect of the same equipment performing different stages of molding processing, and greatly reduce the volume of the equipment. During stamping, the upper mold plate and the lower mold plate are controlled by an independent hydraulic mechanism so that the two can be extended at the same time, so that the upper mold plate and the lower mold plate can contact faster to reduce the stamping time. Compared with the traditional one-way stamping, when the stamping of each link is completed, the multi-axis robot arm can pick up the material through the vacuum suction plate and wait for the material to be put down again after switching to the next process, which significantly improves the work efficiency and solves the problem that the existing automotive parts need to go through at least three sets of molds for drawing, knife breaking and shaping in sequence before they can be finally formed during the stamping operation, and each stamping mold is usually only responsible for one link, and the production efficiency is low.

[0016] By arranging a nozzle rack at the front end of the first hexagonal turntable and the second hexagonal turntable, and arranging a plurality of blowing heads at the front end of the nozzle rack, since the mold is used in a group of three for unidirectional rotation, whenever the mold to be positioned is rotated to the direction of the blowing pipe, an external cooling fan can be used in conjunction with a high-pressure air pump to connect the pipe joint on the nozzle rack, and cold air can be sprayed out from the plurality of blowing heads in front of the nozzle rack to perform a spray cooling and dust removal treatment on the mold in that direction so as to facilitate the next stamping. During the whole process, the three groups of molds can be continuously cooled in sequence. At the same time, the cooling fans located at the ends of the first hexagonal turntable and the second hexagonal turntable introduce external air into the inner cavity of the first hexagonal turntable and the second hexagonal turntable, and cooperate with the plurality of fins at the bottom of the positioning die groove, so that the heat conducted from the surface is discharged from the heat dissipation groove, and the double heat dissipation inside and outside significantly improves the heat dissipation performance of the mold, meets the continuous production needs, and solves the problem that the existing mold needs to be stopped for cooling treatment to avoid high-temperature annealing of the mold after a certain number of continuous stampings in a certain link, thereby reducing the production efficiency.

[0017] The present invention installs a vacuum suction plate and a laser scanner on both sides of the output end of the multi-axis robot arm respectively. The vacuum suction plate is responsible for taking and placing materials. After the material shaping and stamping is completed, the multi-axis robot arm can scan the stamped material through the laser scanner on the other side of the output end. During scanning, the laser light source emits structured light, and projects the structured light pattern onto the device under test. At the same time, the CCD cameras on both sides capture the depth information of the molding material using the parallax principle to construct a three-dimensional model of the molding material. After uploading the model through the terminal, it is compared with the defect-free molding material model in the database based on the algorithm. After the comparison, if the difference between the two groups of models is less than the threshold, it is judged that the molding material is defect-free. At this time, the output end of the multi-axis robot arm is switched to the vacuum suction plate on the other side to take out the material for subsequent automated production. After the comparison, if the difference between the two groups of models is greater than the threshold, it is judged that the molding material has obvious defects due to mold wear or device accuracy failure. At this time, the terminal feeds back a signal to the alarm module to remind personnel to come to inspect and maintain the mold to reduce production losses.

[0018] The first hexagonal turntable and the second hexagonal turntable of the present invention are both provided with short edges aligned with the three long edges. During the stamping process, the multi-section output end of the hydraulic telescopic column output end extends out and can be pressed against the stress-bearing edge strips on the short edge surface of the first hexagonal turntable, providing hard support for the bottom to disperse the pressure applied by the downward stamping from above, while the connecting seats on both sides of the first hexagonal turntable and the shock-absorbing struts at the upper end can effectively disperse the pressure fed back during stamping through the stress-bearing edge strips on the short edge of the second hexagonal turntable, and further utilize the first shock-absorbing spring and the second shock-absorbing spring to achieve buffering, rely on the damping rod inside the spring to achieve shock absorption, effectively control the stamping intensity, and significantly improve the service life of the mold.

[0019] By installing permanent magnetic plates on the bottom surfaces of the lower template and the upper template, the lower template and the upper template are fixed to the positioning mold groove by magnetic attraction of the permanent magnetic plate, which is convenient to install. An electromagnet is installed inside the positioning mold groove. When the lower template and the upper template need to be removed, the electromagnet can be started to generate the same magnetic field as the permanent magnetic plate. Relying on the principle of like poles repelling each other, the permanent magnetic plate is separated from the positioning mold groove, and the lower template and the upper template can be removed conveniently using the disassembly groove, which is convenient for mold replacement. Compared with traditional electromagnetic adsorption, the present application does not require power supply after the mold is installed, and relies on the permanent magnet itself to achieve adsorption. The electromagnet needs to be started only when disassembling, so that it generates the same magnetic field as the permanent magnetic plate, and the permanent magnetic plate is separated from the positioning mold groove by magnetic repulsion, thereby saving energy consumption.
