[0002] During the processing of metal workpieces, a stamping device is required to stamp metal profiles into a certain shape. Currently, during stamping construction, the raw materials are manually placed into the mold at the bottom of the stamping device, and by operating the stamping device, the stamping of the raw materials can be completed. The stamped metal profiles fall into the receiving basket at the bottom for unified collection.

[0003] For example, in the patent with the application number: CN201610820274.4, a metal profile automatic stamping machine is disclosed, which includes a blanking mechanism, a feeding mechanism, a receiving mechanism, and a pushing mechanism for pushing the metal profiles in the receiving mechanism towards the blanking mechanism; the receiving mechanism is provided with a feeding port and a discharging port, the feeding port is communicated with the feeding mechanism, and the discharging port is communicated with the blanking mechanism; the pushing mechanism is provided with a pushing arm, and the pushing arm extends into the receiving mechanism; the blanking mechanism includes a notch stamping device and at least one set of stamping devices for another process, and the notch stamping device and the stamping devices for another process are arranged along the walking path of the metal profile. It automatically feeds the receiving mechanism through the feeding mechanism, and then the pushing mechanism pushes the metal profiles in the receiving mechanism towards the blanking mechanism. Since the blanking mechanism includes at least two sets of stamping processing devices, and at least one set is a notch stamping device, therefore, it is possible to process at least a metal profile including notch processing at one time, avoiding the deficiencies brought by step-by-step processing and separate equipment processing.

It is convenient and flexible to use, has strong adaptability, and improves the flexibility and adaptability of the device.

[0032] 3. When the device alternately stamps two raw materials, when the material distribution plate rotates, it can drive the flap linkage assembly to move left and right through the plate body, and the flap linkage assembly can also drive the blanking channel flap assembly to rotate at the same time. As a result, the conversion flap can alternately open the material distribution slots following the rotation of the material distribution plate, enabling the workpieces supported by stamping different types of raw materials to fall from the left blanking slot and the right blanking slot respectively for separate collection. Thus, no additional labor is required for sorting, and it can adapt to the alternate processing and sorting of two raw materials, with strong adaptability and improved flexibility and adaptability of the device.

[0046] Embodiment:

[0047] As shown in the attached Figure 1 to the attached Figure 8 figures:

[0048] The present invention provides a high-safety double-station stamping device for processing metal workpieces, including a mounting plate assembly 1;

[0049] The mounting plate assembly 1 includes a fixed adjustment plate 101 and a station blanking block 102. The front end of the fixed adjustment plate 101 is welded to one side of the station blanking block 102, and the fixed adjustment plate 101 is fixed to the tabletop of the working platform by screwing.

[0050] A station conversion assembly 2 is installed inside the plate body of the fixed adjustment plate 101.

[0051] A flap linkage assembly 4 and a blanking channel flap assembly 5 are installed inside the block body of the station blanking block 102.

[0052] The material distribution plate 3 is rotatably connected inside the fixed adjustment plate 101, and punching die installation holes 301 are provided on both sides of the plate body of the material distribution plate 3. One of the punching die installation holes 301 is on the same vertical line as the punching device.

[0053] The station conversion assembly 2 includes:

[0054] A material plate driving wheel 201 is rotatably connected inside the fixed adjustment plate 101, and the top of the rotating rod of the material plate driving wheel 201 is fixedly connected to the bottom of the material distribution plate 3.

[0055] A manual driving wheel 202 is rotatably connected inside the fixed adjustment plate 101, and a control handle 2021 is fixedly connected to the wheel body of the manual driving wheel 202, and the control rod of the control handle 2021 passes through the arc-shaped groove at the top of the plate body of the fixed adjustment plate 101.

[0056] Both the material plate driving wheel 201 and the manual driving wheel 202 are fan-shaped gears, and the teeth of the material plate driving wheel 201 and the manual driving wheel 202 are engaged and driven with each other. In use, the device has a double-station punching function. The material distribution plate 3 can be controlled to rotate back and forth through the station conversion assembly 2. When raw materials are being punched at one end of the material distribution plate 3, raw materials can be placed in the die at the other end of the material distribution plate 3, so as to complete the punching process by alternately using the two punching dies at both ends of the material distribution plate 3. Moreover, when placing raw materials into the punching die, it is far away from the punching assembly of the punching device, with high safety, protecting the personal safety of workers, being convenient to use, and improving the flexibility and practicality of the device.

[0057] Among them, limit blocks 2011 are provided in the middle of the rotating rod of the material plate driving wheel 201 and inside the rotating hole of the material plate driving wheel 201 in the fixed adjustment plate 101, and the cross-sectional shape of the block body of the limit block 2011 is a quarter circle. In use, the cooperation of the two limit blocks 2011 enables the material distribution plate 3 to only rotate 180 degrees, so as to more accurately position the punching die at the end of the material distribution plate 3 and the punching assembly of the punching device, with accurate positioning and high quality of the punched workpieces.

[0058] Among them, the flap linkage assembly 4 includes:

[0059] Linkage block 401 is inserted at the top of the station blanking block 102;

[0060] Positioning screw 402 is inserted at the top of the block body of the linkage block 401;

[0061] The blanking channel flap assembly 5 includes:

[0062] Linkage gear 501 is rotatably connected inside the station blanking block 102;

[0063] Conversion flap 502 is fixedly connected to the axial center position on the left side of the linkage gear 501;

[0064] Positioning pull rod 503 is fixedly connected to the axial center position on the right side of the linkage gear 501;

[0065] During use, when the same raw material is stamped by this device, the positioning screw 402 of the flap linkage assembly 4 can be pulled out. At this time, when the flap linkage assembly 4 rotates with the material distribution plate 3, it will not drive the conversion flap 502 of the blanking channel flap assembly 5 to rotate. Thus, the stamped workpieces can fall out of the inside of the device from the blanking left slot 1022 or the blanking right slot 1023 for unified collection. When this device alternately stamps two kinds of raw materials, when the material distribution plate 3 rotates, it can drive the flap linkage assembly 4 to move left and right through the plate body, and the flap linkage assembly 4 can simultaneously drive the blanking channel flap assembly 5 to rotate. Thus, the conversion flap 502 can alternately open the material distribution slots following the rotation of the material distribution plate 3, so that the workpieces supported by stamping different types of raw materials can fall from the blanking left slot 1022 and the blanking right slot 1023 respectively for separate collection. Thus, no additional labor is required for sorting, and it can adapt to the alternate processing and sorting of two kinds of raw materials, with strong adaptability, improving the adaptability and flexibility of this device.

[0066] Among them, the cross-sectional shape of the block body of the linkage block 401 is designed as a "T" shape, and a positioning groove 1021 is provided at the top of the station blanking block 102. Both ends of the positioning groove 1021 are designed to be blocked, and the linkage block 401 is inserted inside the positioning groove 1021. During use, the positioning groove 1021 can limit the movement track and the maximum movement limit of the linkage block 401, so that the linkage block 401 will not be skewed, distorted or overly moved during movement, resulting in the device being stuck and ineffective, improving the stability and practicality of this device.

[0067] Among them, a linkage rack 4011 is provided at the bottom of the linkage block 401, and the linkage rack 4011 meshes with the teeth of the linkage gear 501 for transmission. During use, when the linkage block 401 moves, the linkage rack 4011 can drive the linkage gear 501 to rotate to complete the operation of rotating the conversion flap 502, thereby realizing the function of slotting and blanking.

[0068] Among them, spring rotating blocks 5031 are provided at the top of the positioning pull rod 503 and inside the station blanking block 102, and a positioning tension spring 5032 is provided between the two spring rotating blocks 5031. The two ends of the positioning tension spring 5032 are respectively fixedly connected inside the two spring rotating blocks 5031. The spring rotating block 5031 inside the station blanking block 102 is located below the axis of the linkage gear 501. A "Y"-shaped material distribution groove is provided inside the station blanking block 102, and the material distribution groove is composed of a blanking left groove 1022, a blanking right groove 1023, and a material receiving straight groove 1024. The conversion flap 502 is located at the intersection of the grooves of the blanking left groove 1022, the blanking right groove 1023, and the material receiving straight groove 1024. During use, the positioning tension spring 5032 can ensure that the conversion flap 502 will not move accidentally after the material distribution plate 3 rotates completely, thereby stably realizing the operation of slotting and blanking the stamped workpieces, which is flexible and convenient, has a high degree of automation, and improves the stability and flexibility of the device.

[0069] In another embodiment, the positioning screw 402 can be replaced with a positioning pin rod with a smooth outer rod body, which can be directly inserted into the linkage block 401 for use, and it is convenient to install and disassemble.

[0070] Specific usage method and function of this embodiment:

[0071] In the present invention, the stamping die is placed in the stamping die mounting holes 301 at both ends of the material distribution plate 3, and then the stamping raw material is placed into the stamping die to start processing. During stamping, when the control handle 2021 is rotated, the manual driving wheel 202 can drive the material distribution plate 3 to rotate through the material plate driving wheel 201, thereby realizing the alternating use of the two stations at both ends of the material distribution plate 3. The cooperation of the two limit blocks 2011 enables the material distribution plate 3 to only rotate 180 degrees, thereby more accurately positioning the stamping die at the end of the material distribution plate 3 and the stamping assembly of the stamping device. The positioning is accurate, and the quality of the stamped workpieces is high. The device has a double-station stamping function. Through the station conversion assembly 2, the material distribution plate 3 can be controlled to rotate reciprocally. When the raw material at one end of the material distribution plate 3 is being stamped, the raw material can be placed in the die inside the other end of the material distribution plate 3, thereby completing the alternating use of the two stamping dies at both ends of the material distribution plate 3 for stamping processing. Moreover, when placing the raw material into the stamping die, it is far away from the stamping assembly of the stamping device, with high safety, protecting the personal safety of workers, and being convenient to use;

[0072] When stamping the same raw material, the positioning screw 402 of the flap linkage assembly 4 can be pulled out. At this time, when the flap linkage assembly 4 rotates with the material distribution plate 3, it will not drive the conversion flap 502 of the blanking channel flap assembly 5 to rotate. Therefore, the stamped workpieces can fall out of the inside of the device from the left blanking groove 1022 or the right blanking groove 1023 uniformly for collection. When the device is alternately stamping two kinds of raw materials, when the material distribution plate 3 rotates, it can drive the flap linkage assembly 4 to move left and right through the plate body. The positioning groove 1021 can limit the movement track and the maximum movement limit of the linkage block 401, so that the linkage block 401 will not be skewed, distorted or over-moved to cause the device to jam and fail when moving. When the linkage block 401 moves, the linkage rack 4011 can drive the linkage gear 501 to rotate to complete the operation of rotating the conversion flap 502, changing the on-off state between the material receiving straight groove 1024, the left blanking groove 1022 and the right blanking groove 1023, and realizing the function of slotting blanking. The positioning tension spring 5032 can ensure that the conversion flap 502 will not move accidentally after the material distribution plate 3 rotates, so as to stably realize the operation of slotting blanking for the stamped workpieces. Moreover, the conversion flap 502 can alternately open the material distribution slots following the rotation of the material distribution plate 3, so that the workpieces supported by stamping different types of raw materials can fall from the left blanking groove 1022 and the right blanking groove 1023 respectively for separate collection. Therefore, no additional labor is required for sorting, and it can adapt to the alternate processing and sorting of two kinds of raw materials, with strong adaptability.
