The above-mentioned metal sheets are usually embossed using an embossing device. The existing embossing device generally includes an embossing upper mold, an embossing lower mold, a material discharge drive, an embossing drive and a material pick-up drive. When the material is embossed, the material is placed on the embossing lower mold by the material discharge drive, and then the embossing drive drives the embossing upper mold to move downward and close the mold with the embossing lower mold to achieve embossing of the material. After the embossing is completed, the embossing drive drives the embossing upper mold to reset, and finally the material after embossing is taken out by the material pick-up drive, and then the above embossing process is repeated.

[0003] It was found during use that when the stamped material is taken out from the stamping lower die, it is necessary to clamp the material by a clamping member connected to the material taking drive before taking it away, and the clamping operation easily causes deformation of the material.

[0042] See also Figures 1 to 3 The stamping device provided in the embodiment of the present application is now described. The stamping device provided in the present embodiment is used to stamp a material 10 such as a plate-shaped metal or a metal product. The stamping device includes a base 100, a blanking member 200, a first positioning member 310, a first positioning drive 410, a first die 510 and a first die drive 610. Figures 4 to 7 The material discharge member 200 is arranged on the base 100, and the material discharge member 200 is provided with a material channel 210, a feed port 220, a discharge port 230, a first positioning port 240 and a first stamping port 250. The material channel 210 extends from the top of the material discharge member 200 to the bottom of the material discharge member 200, and the feed port 220, the discharge port 230, the first positioning port 240 and the first stamping port 250 are respectively connected with the material channel 210, the feed port 220 is located above the discharge port 230, and the first positioning port 240 and the first stamping port 250 are located between the feed port 220 and the discharge port 230; the first positioning member 310 can be movably arranged in the first positioning port 240; the first positioning drive 410 is used to drive the first positioning member 310 to approach or move away from the material channel 210, so that the material 10 is fixed at the first predetermined position 211 of the material channel 210 or the material 10 is moved from the first predetermined position 211 (please refer to Figure 6 ) release; the first die 510 can be movably inserted into the first imprinting port 250; the first die drive 610 is used to drive the first die 510 to move closer to or away from the material channel 210 to imprint or release the material 10 located at the first predetermined position 211.

[0043] It should be noted that the material channel 210 extends from the top of the lower material part 200 to the bottom of the lower material part 200, which can be understood as the material channel 210 being substantially vertical. Preferably, the angle between the material channel 210 and the vertical direction is between 0° and 10°.

[0044] It should also be noted that the first positioning member 310 can be arranged on the same side of the blanking member 200 as the first die 510, or can be arranged on two opposite sides of the blanking member 200 respectively. The selection can be made as needed, and is not limited here. The first positioning member 310 can be a structure such as a rod or a plate, and is connected to the power output end of the first positioning drive 410. The first positioning drive 410 can be a linear drive such as an electric push rod, an electromagnetic push rod, a cylinder, a hydraulic cylinder, etc. The first positioning member 310 can also be directly set as the output shaft of the linear drive, and correspondingly, the first positioning drive 410 is the part of the linear drive used to provide power for the output shaft. For example, the first positioning member 310 is a cylinder guide rod, and the first positioning drive 410 is a cylinder body used to drive the cylinder guide rod; for another example, the first positioning member 310 is an iron core, and the first positioning drive 410 is an electromagnet used to drive the iron core.

[0045] Specifically, the first positioning driver 410 and the first die driver 610 can both be disposed on the base 100 or the blanking piece 200 , which is not limited here.

[0046] Specifically, the blanking piece 200 may be assembled from a plurality of plate-like structures.

[0047] Compared with the prior art, the stamping device provided in this embodiment, when in use, the material 10 enters the material channel 210 from the feed port 220 and falls under the action of gravity. Before the material 10 completely falls to the first predetermined position 211 of the material channel 210 or before the material 10 enters the feed port 220, the first positioning drive 410 drives the first positioning member 310 to move in the direction close to the material channel 210, which can stop the material 10 from continuing to fall, so that the material 10 stays at the first predetermined position 211 above the first positioning member 310. Then, the first stamping device 410 drives the first positioning member 310 to move in the direction close to the material channel 210, so as to stop the material 10 from continuing to fall, so that the material 10 stays at the first predetermined position 211 above the first positioning member 310. The die driver 610 drives the first die 510 to move in a direction close to the material channel 210 to perform an imprinting operation on the material 10. After the imprinting operation is completed, the first die driver 610 drives the first die 510 to move in a direction away from the material channel 210, and the first die 510 is separated from the surface of the material 10. Then, the first positioning driver 410 drives the first positioning member 310 to move in a direction away from the material channel 210 to release the material 10 from the first predetermined position 211. The material 10 falls to the discharge port 230 of the material channel 210 under the action of gravity. In the imprinting device provided in this embodiment, after the imprinting of the material 10 is completed, the first positioning driver 410 drives the first positioning member 310 to move in a direction away from the material channel 210, so that the material 10 after the imprinting is completed can be automatically separated from the first predetermined position 211 (i.e., the position where the first die 510 performs the imprinting operation) under the action of gravity, and there is no need to use other clamping equipment to remove the imprinted material 10 from the first predetermined position 211, which is not easy to cause deformation of the material 10.

[0048] In this embodiment, the material 10 (metal sheet) falls safely under the protection of the material channel 210. There is no need to transport the material 10 (metal sheet) from the first positioning port 240 to the first stamping port 250 through a clamping device, nor is there any need to transport the material 10 (metal sheet) from the first stamping port 250 to a location away from the stamping device, thereby avoiding deformation caused by clamping and deformation caused by collision with foreign objects during transportation.

[0049] In another embodiment of the present application, the stamping device further includes a controller (not shown), which is electrically connected to the first positioning driver 410 and the first stamping die driver 610 respectively; see Figure 3 and Figure 6The stamping device further includes a first detection unit 710 , which is electrically connected to the controller and is used to detect whether the material 10 passes through the material channel 210 between the feed port 220 and the first positioning port 240 .

[0050] Specifically, the controller is used to receive a signal fed back by the first detection unit 710 , and to control the start and stop of the first positioning driver 410 and the first die driver 610 .

[0051] Specifically, the first detection unit 710 can be arranged on the base 100 or the blanking piece 200, which is not limited here. The first detection unit 710 has various forms, for example, the first detection unit 710 is a photoelectric sensor, and the blanking piece 200 is provided with a detection port for the light emitted by the photoelectric sensor to pass through, the photoelectric sensor can be arranged in the detection port, or can be arranged outside the detection port, and can be arranged as needed, and the photoelectric sensor can be specifically a slot type photoelectric sensor, a beam type photoelectric sensor or a reflector type photoelectric sensor; for another example, the first detection unit 710 is a metal sensing sensor, the blanking piece 200 is a non-metallic blanking piece, and the metal sensing sensor is arranged on the outer wall of the blanking piece 200, at this time, the detection end of the metal sensing sensor does not need to penetrate into the material channel 210 for detection; for another example, the first detection unit 710 is a metal sensing sensor, the blanking piece 200 is a non-metallic blanking piece or a metal blanking piece, and the blanking piece 200 is provided with a detection port, and the detection end of the metal sensing sensor detects the material 10 through the detection port.

[0052] When the stamping device provided in this embodiment is in use, the first detection unit 710 detects the material 10 and feeds back a signal to the controller. The controller controls the first positioning drive 410 to drive the first positioning member 310 to move toward the material channel 210 based on the signal fed back by the first detection unit 710, thereby ensuring that before the material 10 completely falls to the first predetermined position 211, the first positioning member 310 is already in a position that can limit the material 10 from continuing to fall, thereby preventing the material 10 from falling directly to the discharge port 230 without being stamped.

[0053] In another embodiment of the present application, please refer to Figure 3 and Figure 6 The first detection unit 710 is disposed between the feed port 220 and the first positioning port 240 , and is used to detect whether the material 10 passes through the first detection unit 710 .

[0054] Specifically, the first detection unit 710 may be a metal sensing sensor, and the metal sensing sensor may detect the material 10 approaching the metal sensing sensor without actually contacting the material 10 .

[0055] In the imprinting device provided in this embodiment, the detection end of the first detection unit 710 is arranged in the material channel 210, and the detection accuracy is high.

[0056] In another embodiment of the present application, please refer to Figure 3 and Figure 5 The stamping device also includes a second positioning member 320, a second positioning drive 420 and a second detection unit 720. The unloading member 200 is also provided with a second positioning port 260 which is connected to the material channel 210 and is located above the first detection unit 710. The second positioning member 320 can be movably inserted into the second positioning port 260. The second positioning drive 420 is used to drive the second positioning member 320 to approach or move away from the material channel 210 so that the material 10 is fixed at the second predetermined position 212 of the material channel 210 or the material 10 is released from the second predetermined position 212. The second detection unit 720 is used to detect whether the material 10 passes through the material channel 210 between the feed port 220 and the second positioning port 260.

[0057] Preferably, see Figure 5 The second detection unit 720 is disposed between the feed port 220 and the second positioning port 260 , and a detection end of the second detection unit 720 penetrates into the material channel 210 .

[0058] Optionally, the second detection unit 720 is a metal induction sensor.

[0059] Specifically, the principle of the second positioning driver 420 driving the second positioning member 320 is the same as the principle of the first positioning driver 410 driving the first positioning member 310 , which will not be described in detail here. The second positioning driver 420 can be disposed on the base 100 or the blanking member 200 .

[0060] In the embossing device provided in this embodiment, when working, the second detection unit 720 detects the first material 10 in the material channel 210 and feeds back to the controller, and the controller controls the second positioning drive 420 to drive the second positioning member 320 to move away from the material channel 210, so that the first material 10 continues to fall; then, the first die 510 performs embossing on the first material 10, the first detection unit 710 detects the first material 10 and feeds back to the controller, and the controller controls the first positioning drive 410 to drive the first positioning member 310 to move toward the direction close to the material channel 210, so that the first material 10 stays in the first die 510. The controller controls the first die driver 610 to drive the first die 510 to perform an imprinting operation on the first material 10; then, the controller controls the first die driver 610 to drive the first die 510 to move away from the material channel 210, so that the first die 510 is separated from the surface of the material 10, and controls the first positioning drive 410 to drive the first positioning member 310 to move away from the material channel 210, so as to release the material 10 from the first predetermined position 211, and the material 10 falls to the discharge port 230 of the material channel 210 under the action of gravity, thereby completing the imprinting process of the first material 10.

[0061] While the first material 10 is being embossed, if the second detection unit 720 detects that a second material 10 (i.e., the material 10 that enters the material channel 210 immediately after the first material 10) enters the material 10 channel, and the first die 510 and the first positioning member 310 have both released the first material 10 that has been embossed, at this time, the controller controls the second positioning drive 420 to drive the second positioning member 320 to move away from the material channel 210, so that the second material 10 falls to the first predetermined position 211, and the first die 510 performs an embossing operation on the second material 10. While the first material 10 is being embossed, if the second detection unit 720 detects the second material 10 and the first material 10 is still in the first predetermined position 211, the controller controls the second positioning drive 420 to drive the second positioning member 320 to move toward the material channel 210, so that the second material 10 stays at the second predetermined position 212, thereby avoiding the second material 10 and the second material 10 from being simultaneously accumulated at the first predetermined position 211, causing material jamming at the first predetermined position 211.

[0062] In another embodiment of the present application, please refer to Figure 8 and Fig. 9The stamping device also includes a first stamping plate 810 and a first elastic member 811. The first stamping plate 810 can be movably arranged on a side of the unloading member 200 close to the first stamping port 250. The first stamping plate 810 is provided with a first through hole 812 corresponding to the position of the first stamping port 250 and used for the first die 510 to pass through. The first stamping plate 810 can be driven by the first die drive 610 to approach the material channel 210 so as to press the material 10 located at the first predetermined position 211 through the first stamping port 250, and the first stamping plate 810 can be moved away from the material channel 210 under the action of the first elastic member 811 to release the pressure on the material 10 located at the first predetermined position 211.

[0063] Specifically, the first elastic member 811 may be a rigid spring or an elastic screw, etc., which may be set as needed, and the number of the first elastic members 811 may be one, two, three, four, etc., which may be set as needed.
