[0020] See also Figure 1-7The present invention provides a technical solution: an automatic loading high-speed servo hydraulic punching machine system and a working method thereof, comprising a punching machine body 7, a loading conveyor belt 8, a discharging conveyor belt 9, a flipping and discharging part 3, a punching table 1 and a switching table 2, The punching table 1 is fixedly connected to one end of the punching machine body 7, the switching table 2 is rotatably connected to the middle side of the punching table 1, at least one set of concave dies 201 is eccentrically arranged inside the switching table 2, and a convex die 202 is hydraulically driven on the upper side of the punching machine body 7; The switching table 2 drives the female mold 201 to move back and forth between the lower side of the male mold 202, the flip unloading part 3 and the loading conveyor belt 8; The loading conveyor belt 8 is used to transport the stamping sheet 6 to the switching table 2. The upper end surface of the die 201 is lower than the upper end surface of the switching table 2, and the distance between the two is equal to the thickness of the stamping sheet 6. The punch 202 cooperates with the die 201 to punch the stamping sheet 6 into a workpiece body 5; The turning and unloading part 3 is arranged at one side of the punching table 1 , and is used for clamping the punched workpiece body 5 and turning it onto the unloading conveyor belt 9 .

[0021] First, the stamping sheet 6 to be formed is transported to the upper side of the switching table 2 in sequence through the feeding conveyor belt 8. Due to the distance difference between the upper end surface of the die 201 and the upper end surface of the switching table 2, the stamping sheet 6 falls into the upper side of the die 201, aligns its own positioning, and ensures the subsequent displacement of the stamping sheet 6 and the stability of stamping; then, the stamping sheet 6 is driven by the switching table 2 to move to the lower side of the punch 202, and then the punch 202 is driven by the hydraulic system (the servo hydraulic system is a prior art in this field, so it will not be described in detail here). 02 descends, stamping the stamping sheet 6 into the die 201 to form the workpiece body 5; then the workpiece body 5 is driven to move to the flip unloading part 3 through the switching table 2, and the flip unloading part 3 clamps the workpiece body 5, unloads it, and flips it onto the unloading conveyor belt 9, thereby completing automatic unloading; finally, the switching table 2 drives the empty die 201 to reset to the loading conveyor belt 8, thereby starting the next round of stamping and forming, realizing automated continuous stamping work, without the need for manual intervention in loading and unloading, and greatly improving work efficiency; Preferably, three groups of concave dies 201 are provided, which respectively correspond to the stamping process, the unloading process and the loading process, so that the three processes can be carried out simultaneously, further improving the work efficiency.

[0022] The upper side of the punch 202 is fixedly connected to the upper template 203, and a plurality of guide telescopic columns 204 are arranged at the upper end of the upper template 203. The upper ends of the guide telescopic columns 204 are connected to the punch body 7. A circular groove is opened at the lower end of the punch 202, and a limit plate 205 is arranged in the circular groove. The circular groove is adapted to the limit plate 205, and a push rod 206 is fixedly connected to the upper end of the limit plate 205. The push rod 206 passes through the upper template 203 and the punch 202 and slides with them.

[0023] Preferably, in order to prevent the workpiece body 5 from adhering to the punch 202 after the stamping work is completed, so that it cannot be smoothly demolded into the die 201, resulting in the workpiece body 5 being unable to be subsequently unloaded onto the unloading conveyor belt 9, a limit plate 205 is provided. The limit plate 205 is provided on the lower side of the punch 202 and embedded in the circular groove, so as not to affect the normal forming of the workpiece body 5. When the punch 202 completes the stamping and forming and rises to reset, the push rod 206 and the limit plate 205 maintain their height positions, and the punch 202 rises relative to the limit plate 205, so that the limit plate 205 can press the formed workpiece body 5 into the die 201, so that it falls off the punch 202, and the demolding work is completed.

[0024] A cylindrical groove 701 is provided on the inner side of the upper end of the punch body 7, and a center plate 207 is fixedly connected to the upper end of the push rod 206. A center rod 209 is provided on the upper end of the center plate 207. The center rod 209 penetrates and extends to the inner side of the cylindrical groove 701. A pair of fan-shaped blocks 101 are fixedly connected to the upper end of the center rod 209. The lower ends of the fan-shaped blocks 101 are provided with oblique chamfers. Square grooves are provided at both ends of the middle side of the cylindrical groove 701. A spring telescopic rod 102 is provided in the square groove. A brake block 103 is provided at one end of the spring telescopic rod 102. The brake block 103 is slidably matched with the square groove. An arc-shaped inclined surface is provided on the inner side of the brake block 103, and the arc-shaped inclined surface is adapted to the fan-shaped block 101.

[0025] Preferably, when it is necessary to control the limit plate 205 to keep its height position unchanged when the punch 202 is reset, a fan-shaped block 101 is provided. Specifically, in the initial state, the upper end of the center rod 209 contacts the upper end of the cylindrical groove 701. When stamping is required, the punch 202 descends, driving the limit plate 205 and the push rod 206 to descend synchronously. The push rod 206 drives the center plate 207 and the center rod 209 to descend until the fan-shaped block 101 contacts the brake block 103, and pushes the brake block 103 into the square groove along its arc slope, so that the fan-shaped block 101 moves to the making block. At the lower side of the moving block 103, the brake block 103 pops out immediately and blocks the sector-shaped block 101. At the same time, the punch 202 also completes the stamping work and can rise and reset. At this time, the sector-shaped block 101 is stuck, so that the center rod 209, the center plate 207, the push rod 206 and the limit plate 205 are limited in height, so that the punch 202 can rise relative to the limit plate 205, and the limit plate 205 limits the workpiece body 5 to complete the demoulding work. That is to say, when the stamping is completed, the position of the limit plate 205 can be automatically limited. The two have good synchronization and a high degree of automation.

[0026] The lower end of the center rod 209 is rotatably connected to the center plate 207 and is provided with a torsion spring. The torsion spring drives the sector-shaped clamping block 101 at the upper end of the center rod 209 to align with the brake block 103 .

[0027] Preferably, when demolding is completed and the limit plate 205 needs to rise and reset, the fan-shaped block 101 is driven to rotate a certain angle relative to the center plate 207 through the center rod 209, so that the position of the fan-shaped block 101 and the brake block 103 are offset, and the restriction on the fan-shaped block 101 can be released, so that the center rod 209, the center plate 207, the top rod 206 and the limit plate 205 can rise and reset, and then under the reset action of the torsion spring, the center rod 209 and the fan-shaped block 101 are rotated and reset.

[0028] A pair of grooves are provided on the upper side of the center plate 207, and a clamping plate 104 is arranged in the groove. A driving block 105 is fixedly connected to the inner side of the clamping plate 104, and the inner side of the driving block 105 is in contact with the center rod 209. A guide rod 106 is fixedly connected to the lower end of the clamping plate 104. The guide rod 106 passes through the center plate 207 and slides with it. The guide rod 106 is fixedly connected to the upper template 203, and a spring member is sleeved on the outer side of the guide rod 106. A pair of arc-shaped inclined blocks 107 are fixedly connected to the lower end of the center rod 209, and an inclined surface is provided at one end of the driving block 105, and the arc-shaped inclined block 107 is adapted to the driving block 105.

[0029] Preferably, when it is necessary to drive the center rod 209 to rotate an angle, a driving block 105 is provided. Specifically, when the punch 202 completes the stamping and forming work and rises to reset, the guide rod 106 and the clamping plate 104 are pushed up, and the clamping plate 104 drives the driving block 105 to rise relative to the arc-shaped inclined block 107. The driving block 105 is pushed along the inclined surface of the arc-shaped inclined block 107, so that the arc-shaped inclined block 107 moves in a circular shape, which can drive the center rod 209 to rotate. Then, driven by the punch 202, the center plate 207 is pushed up, so that the fan-shaped clamping block 101 can be moved to the upper side of the brake block 103. Then, under the resetting action of the spring member, the limit plate 205 is re-embedded in the lower end of the punch 202 to complete the resetting. In other words, the limit plate 205 can be automatically reset only by the displacement of the punch 202, thereby realizing the stable demolding of the workpiece body 5. No additional driving components or control programs are required for control, thus saving costs.

[0030] An adapting groove is provided at the center of the female mold 201, a push plate 4 is provided in the adapting groove, a push rod 401 is fixedly connected to the lower side of the push plate 4, the adapting groove is adapted to the push plate 4, and the push rod 401 penetrates the female mold 201 and slides with it; A cylinder 402 is fixedly connected to the inner side of the lower end of the punch body 7 . The cylinder 402 is arranged adjacent to the flipping and unloading part 3 . The driving end of the cylinder 402 is used to push the push rod 401 .

[0031] Preferably, in order to prevent the workpiece body 5 from getting stuck in the die 201 and making it impossible to unload, a cylinder 402 is provided. After stamping, the workpiece body 5 moves to the flip unloading portion 3. At this time, the push rod 401 corresponds to the position of the cylinder 402, so that the push rod 401 and the push plate 4 are pushed up by the driving end of the cylinder 402, and the push plate 4 can push the workpiece body 5 out to complete the demolding.

[0032] The flip unloading part 3 includes a unloading plate 301, one end of which is provided with an arc groove, a C-shaped frame 302 is fixedly connected to the inner side of the arc groove, one end of the C-shaped frame 302 is fixedly connected to a limit frame 303, and the diameter of the C-shaped frame 302 is not less than the maximum diameter of the workpiece body 5.

[0033] Next, when the demoulded workpiece body 5 needs to be taken out, a stripper plate 301 is provided. In the initial state, the stripper plate 301 is horizontally arranged on the stamping table 1, and the arc groove coincides with the axis of the die 201. Since the diameter of the C-shaped frame 302 is not less than the maximum diameter of the workpiece body 5, when the workpiece body 5 is lifted by the push plate 4, it passes through the C-shaped frame 302, and then the stripper plate 301 drives the C-shaped frame 302 and the limit frame 303 to move horizontally, so that the limit frame 303 moves to the middle side of the workpiece body 5. Since the distance between the two ends of the limit frame 303 is smaller than the diameter of the C-shaped frame 302, the limit frame 303 is clamped at the two ends of the workpiece body 5, and then the unloading plate 301 can flip it over and flip the workpiece body 5 onto the unloading conveyor belt 9. The workpiece body 5 contacts the stationary unloading conveyor belt 9, and then the unloading plate 301 is horizontally displaced in the opposite direction and reset, so that the limit frame 303 is away from the workpiece body 5, and the C-shaped frame 302 coincides with the axis of the workpiece body 5, and the unloading plate 301 can be flipped and reset to complete the unloading.

[0034] A pair of support seats 304 are fixedly connected at one end of the punching table 1, and a rotating shaft 305 is rotatably connected between the support seats 304. The rotating shaft 305 is driven by a motor assembly. A gear 306 is fixedly connected to the middle side of the rotating shaft 305. A tooth groove is opened on the lower side of the discharge plate 301, and the gear 306 is meshed with the tooth groove.

[0035] Preferably, the motor assembly drives the shaft 305 to rotate, driving the gear 306 to rotate. The gear 306 drives the unloading plate 301 through meshing connection, so that the unloading plate 301 can be displaced horizontally, thereby allowing the limit frame 303 to clamp or release the workpiece body 5.

[0036] A pair of flip seats 307 are rotatably connected on both sides of the gear 306, the rotating shaft 305 passes through the flip seat 307 and is rotatably connected thereto, one end of the flip seat 307 is fixedly connected to a guide block 308, and a guide groove 309 is provided at the lower end of the discharge plate 301, and the guide block 308 slides in cooperation with the guide groove 309.

[0037] When it is necessary to flip the unloading plate 301, a guide block 308 is provided to slide with the guide groove 309. Specifically, the gear 306 is driven by the rotating shaft 305 to make the unloading plate 301 move horizontally, so that the limit frame 303 clamps the workpiece body 5. When the unloading plate 301 moves, the guide block 308 slides with the guide groove 309 for guidance. After the limit frame 303 clamps the workpiece body 5, one end of the guide groove 309 contacts the guide block 308, so that the unloading plate 301 cannot continue to move horizontally, and the rotating shaft 305 continues to rotate. When the driving force is greater than the weight of the unloading plate 301 itself, the rotating shaft 305 directly drives the flip seat 307 and The unloading plate 301 flips over, thereby driving the workpiece body 5 to flip over to the unloading conveyor belt 9. Then, the rotating shaft 305 rotates in the opposite direction, thereby driving the unloading plate 301 to move horizontally in the opposite direction, so that the limit frame 303 releases the workpiece body 5. At this time, the other end of the guide groove 309 contacts the guide block 308, so that the unloading plate 301 cannot continue to move. Similarly, the rotating shaft 305 can lead it to flip and reset, and the unloading plate 301, C-shaped frame 302 and limit frame 303 can return to their original positions, waiting for the next clamping and unloading. In other words, the automatic flipping, unloading and resetting of the workpiece body 5 can be achieved only by the forward and reverse rotation of the rotating shaft 305, which has a high degree of automation and strong practicality.
