[0038] Please refer to Figure 3 and Figure 4 ​​​The lower die assembly 101 comprises a lower die 10, a positioning member 20 and a pushing member 30. The lower die 10 is provided with a blanking groove 11. The positioning member 20 is arranged around the blanking groove 11 on the lower die 10 and positions the main body 201 in the first direction. The pushing member 30 is slidably arranged on the lower die 10 in the second direction and is correspondingly arranged with the positioning member 20 in the second direction. The pushing member 30 is used to move close to the positioning member 20 to position the main body 201 to the positioning member 20 in the second direction. Please refer to Figure 5 and Figure 6 The upper die assembly 102 comprises an upper die 40, a fixing member 50, a pressing member 60, an elastic member 70 and a cutting member 80. The upper die 40 is movably arranged above the lower die 10. The fixing member 50 is connected with the upper die 40. The pressing member 60 is correspondingly arranged with the positioning member 20 in the third direction and is movably connected with the fixing member 50. The two ends of the elastic member 70 are elastically abutted with the fixing member 50 and the pressing member 60 respectively. The pressing member 60 is used to press the connecting body 202 to the positioning member 20 in the third direction under the driving of the fixing member 50 and compress the elastic member 70. The cutting member 80 is fixedly connected with the fixing member 50 and is correspondingly arranged with the blanking groove 11 in the third direction. The cutting member 80 is used to cut the connecting body 202 and the connecting part 300 under the driving of the fixing member 50, so that the cut-off connecting part 300 falls into the blanking groove 11. Exemplarily, the elastic member 70 can be a spring.

[0039] The punching device 100 is used in actual use. First, the positioning member 20 positions the main body 201 in the first direction. Then, the pushing member 30 moves close to the positioning member 20 to position the main body 201 to the positioning member 20 in the second direction. Finally, the upper die 40 drives the pressing member 60 and the cutting member 80 to move close to the lower die 10. The pressing member 60 presses the connecting body 202 to the positioning member 20 in the third direction and compresses the elastic member 70 to the fixing member 50, so as to position the product 200 in three directions. The cutting member 80 cuts the connecting body 202 and the connecting part 300 under the driving of the lower die 10, so that the cut-off connecting part 300 falls into the blanking groove 11. In this way, the positioning member 20, the pushing member 30 and the pressing member 60 position the product 200 in the first direction, the second direction and the third direction respectively, so that the cutting member 80 accurately cuts the connecting body 202 and the connecting part 300, avoids the deformation of the product 200 and improves the cutting precision and the quality of the product 200.

[0040] In the embodiment, the positioning member 20 comprises a positioning body 21 and a supporting body 22. The positioning body 21 is arranged on the lower die member 10 around the blanking groove 11 and is provided with a positioning groove 211. The positioning groove 211 is arranged on the side of the positioning body 21 away from the lower die member 10 and is matched with the main body 201. The positioning groove 211 is used for receiving the main body 201 and clamping the main body 201 in the first direction, so as to position the main body 201 in the first direction. The supporting body 22 is protruded on the side of the positioning body 21 away from the lower die member 10 and is matched with the connecting body 202. The supporting body 22 is used for supporting the connecting body 202. Exemplarily, the positioning body 21 can be any positioning plate, positioning block or similar positioning part capable of positioning the main body 201. The supporting body 22 is any supporting part, supporting block or similar supporting plate capable of supporting the connecting body 202.

[0041] In this way, the positioning groove 211 arranged on the positioning body 21 receives the main body 201, so that the two groove walls of the positioning groove 211 clamp the main body 201 in the first direction, thereby positioning the main body 201 in the first direction. The connecting body 202 is supported by the supporting body 22, so as to ensure that the cutting member 80 stably cuts the connecting part between the connecting body 202 and the material head 300, and avoid deformation of the connecting body 202 during the cutting process. In addition, the pushing member 30 positions the main body 201 to the supporting body 22 in the second direction, thereby positioning the main body 201 in the second direction.

[0042] Please refer to Figure 1 and Figure 4 In the embodiment, the lower die member 10 is provided with a receiving groove 12. The receiving groove 12 is arranged on the side of the positioning member 20 away from the blanking groove 11. The receiving groove 12 is used for receiving the product 200 after cutting. The punching device 100 further comprises a material collecting assembly 103. The material collecting assembly 103 is arranged on the side of the lower die member 10 away from the positioning member 20 and is communicated with the receiving groove 12. The material collecting assembly 103 is used for collecting the product 200.

[0043] In this way, the product 200 after cutting is moved into the material collecting assembly 103 through the receiving groove 12, so that the material collecting assembly 103 collects the product 200, thereby facilitating subsequent centralized processing of the product 200.

[0044] Please refer to Figure 7 In the embodiment, the material collecting assembly 103 comprises a guide member 90 and a material collecting member 110. The guide member 90 is arranged on the side of the lower die member 10 away from the positioning member 20 and is provided with a guide groove 91. The guide groove 91 is communicated with the receiving groove 12. The guide groove 91 is used for receiving the product 200 moved out of the receiving groove 12. The material collecting member 110 is connected with the guide member 90 and is provided with a material collecting groove 111. The material collecting groove 111 is communicated with the guide groove 91. The material collecting groove 111 is used for receiving the product 200 moved out of the guide groove 91 to collect the product 200.

[0045] Therefore, by setting the two ends of the guide groove 91 in communication with the receiving groove 12 and the collecting groove 111 respectively, the receiving groove 12, the guide groove 91 and the collecting groove 111 form a collecting channel, so that the cut product 200 moves into the preset position along the preset path of the collecting channel, facilitating the centralized collection of the product 200.

[0046] It can be understood that in the embodiment of the present application, the stub 300 is connected with a plurality of products 200, and therefore the number of the positioning member 20, the pushing member 30, the fixing member 50, the pressing member 60, the elastic member 70 and the cutting member 80 provided in the punching device 100 is multiple and corresponds one by one, so that the cutting of the plurality of products 200 connected with the stub 300 can be realized. Further, the number of the receiving groove 12, the guide member 90 and the collecting member 110 is also multiple and corresponds one by one with the plurality of positioning members 20, so that the plurality of collecting members 110 of the collecting assembly 103 respectively collect the products 200 cut by the corresponding cutting members 80, so as to classify the products 200, facilitate the subsequent detection, processing and other operations of the classified products 200, and at the same time, for the products 200 with problems, it is also convenient to trace the source of the products 200, reduce the difficulty of tracing the problem cause and the time of solving the problem. Among them, the collecting grooves 111 of the plurality of collecting members 110 are located on the same side, which is convenient for the operator to collect and classify the products 200.

[0047] Please continue to refer to Figure 7 In the embodiment, the groove bottom of the guide groove 91 and the groove bottom of the collecting groove 111 are both arc-shaped portions 92.

[0048] Therefore, by setting the groove bottom of the guide groove 91 and the groove bottom of the collecting groove 111 as the arc-shaped portions 92, the cut product 200 moves slowly and smoothly in the guide groove 91 and the collecting groove 111, avoiding the collision between the product 200 and the guide member 90 and the collecting member 110 during the collecting process, and further improving the quality of the product 200.

[0049] Please refer to Figure 1 and Figure 7 In the embodiment, the collecting assembly 103 further comprises a limiting member 120, the limiting member 120 is arranged on the side of the lower die member 10 away from the positioning member 20 and is provided with a limiting groove 121, the limiting groove 121 receives the guide member 90 and is detachably connected with the guide member 90, and the limiting member 120 is used for limiting the guide member 90.

[0050] Therefore, by receiving the guide member 90 in the limiting groove 121 and detachably connecting with the guide member 90, the limiting member 120 limits the guide member 90, so that the guide groove 91 accurately and quickly communicates with the receiving groove 12, avoiding the misalignment between the guide groove 91 and the receiving groove 12, and ensuring the smooth receiving of the product 200.

[0051] Please refer toFigure 4 In the embodiment, the lower die set 10 is further provided with a guide slope 13, which is arranged obliquely relative to the positioning body 21 of the positioning member 20, and the two ends of the guide slope 13 are connected with the material receiving groove 12 and the positioning member 20 respectively. The guide slope 13 is used to guide the cut product 200 to move into the material receiving groove 12.

[0052] In this way, by arranging the guide slope 13, the cut product 200 can stably enter the material receiving groove 12 through the guide slope 13, so that the transport direction of the product 200 does not deviate and collides with other components, which is beneficial to the stable collection of the product 200.

[0053] Please refer to Figure 5 and Figure 6 In the embodiment, the side of the pressing member 60 away from the cutting member 80 is arranged in the limiting hole 61. The fixing member 50 includes a fixing body 51 and a pressing body 52. The fixing body 51 is connected with the upper die set 40 and the cutting member 80 respectively and is provided with a receiving groove 511. The receiving groove 511 receives the end of the pressing member 60 away from the lower die set 10 and is in communication with the limiting hole 61. The groove bottom of the receiving groove 511 abuts against the two ends of the elastic member 70 respectively. One end of the pressing body 52 is connected with the fixing body 51, and the other end of the pressing body 52 is inserted into the limiting hole 61. The pressing body 52 is used to abut against the hole wall of the limiting hole 61 to limit the pressing member 60.

[0054] In this way, by arranging the specific structure of the fixing member 50, when the pressing member 60 does not press the connecting body 202 to the supporting body 22, the pressing body 52 abuts against the hole wall of the limiting hole 61 adjacent to the lower die set 10, so as to limit the pressing member 60 from separating from the fixing body 51, thereby realizing the movable connection between the pressing member 60 and the fixing member 50. When the pressing member 60 has pressed the connecting body 202 to the supporting body 22, the pressing member 60 compresses the elastic member 70 to the groove bottom of the receiving groove 511, so that the pressing member 60 flexibly presses the connecting body 202, and at the same time, the pressing body 52 abuts against the hole wall of the limiting hole 61 away from the lower die set 10, so as to limit the movement distance of the pressing member 60.

[0055] Please refer to Figure 3 In the embodiment, the pushing member 30 includes a pushing driving body 31, a pushing body 32 and a guide body 33. The pushing driving body 31 is arranged in the lower die set 10. The pushing body 32 is connected with the pushing driving body 31 and is used to move close to the supporting body 22 under the driving of the pushing driving body 31, so as to position the main body 201 in the second direction. One end of the guide body 33 is connected with the pushing body 32, and the other end of the guide body 33 is movably arranged in the lower die set 10 in the second direction. The guide body 33 is used to guide the pushing body 32. Exemplarily, the pushing driving body 31 can be a pneumatic cylinder.

[0056] Thus, by setting the specific structure of the pushing member 30, the pushing body 32 stably moves close to the supporting body 22 under the guidance of the guiding body 33 and the driving of the pushing driving body 31, and the main body 201 is accurately positioned to the supporting body 22 in the second direction.

[0057] Please refer to Figure 4 and Figure 5 In the embodiment, the lower die assembly 10 is provided with a guide hole 14 on the side facing the upper die assembly 40, and the upper die assembly 102 further comprises a guide member 130 which is correspondingly arranged with the guide hole 14 and connected with the upper die assembly 40. The guide member 130 is used to be inserted into the guide hole 14 under the driving of the upper die assembly 40, so as to guide the cutting member 80.

[0058] Thus, by setting the guide member 130, the guide member 130 is inserted into the guide hole 14 under the driving of the upper die assembly 40, so as to guide the movement direction of the cutting member 80, and the cutting member 80 stably cuts the connection between the connecting body 202 and the material head 300, thereby ensuring the cutting precision.

[0059] The working process of the punching device 100 is as follows:

[0060] Firstly, the positioning body 21 positions the main body 201 along the first direction through the positioning groove 211, and the supporting body 22 supports the connecting body 202 connected with the main body 201.

[0061] Then, the pushing driving body 31 drives the pushing body 32 to move close to the supporting body 22 to position the main body 201 to the supporting body 22 along the second direction.

[0062] Next, the upper die assembly 40 drives the pressing member 60 and the cutting member 80 to move close to the lower die assembly 10, the pressing member 60 presses the connecting body 202 to the supporting body 22 along the third direction and compresses the elastic member 70 to the fixing member 50, so as to position the product 200 in three directions, and the cutting member 80 accurately cuts the connection between the connecting body 202 and the material head 300 under the driving of the lower die assembly 10, thereby avoiding the deformation of the product 200 and improving the cutting precision and the quality of the product 200.

[0063] Finally, the cut material head 300 falls into the material falling groove 11, and the cut product 200 falls into the material receiving groove 12 and is moved into the material receiving groove 111 through the guide groove 91.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited.
