Description

Technical Field

[0001] The utility model belongs to the technical field of hardware stamping dies, and in particular relates to a multi-station material taking reverse punching hole structure of a manipulator. Background Art

[0002] In the manufacturing industry, many parts use punching technology to obtain the corresponding shape and size to meet the functional requirements of the product. The hole positions of some products require that the burrs of the product must face outward. In the production process, in order to improve the processing efficiency of the product and control the production cost of the product, the production process uses a connecting rod robot to pick and place the product. The material picking method between each processing step is designed using a connecting rod robot.

[0003] In the punching die of the prior art, the processing method is forward punching, that is, the punch is on the upper die assembly, and the die is on the lower die assembly. When punching, the upper die assembly moves downward and cooperates with the lower die assembly to punch the product, and the waste material falls down after leaving the product. The problem is that according to the burr direction requirements of the product, after the product completes the trimming process and the punching process in sequence, in order to avoid the punching burr direction and the trimming burr direction being one positive and one negative, the product needs to be flipped before the punching process, which increases the operating procedures of the product and reduces the production efficiency of the product. In addition, two sets of connecting rod manipulators need to be added before and after the punching process during the processing. Due to the increase in the number of connecting rod manipulators, the equipment investment cost of the enterprise increases, which is not conducive to product cost control.

[0004] Therefore, further improvements are needed. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments.

[0028] See also Figure 1-4The multi-station material-taking reverse punching hole structure of the manipulator comprises an upper die assembly and a lower die assembly corresponding to the upper and lower parts. The upper die assembly comprises an upper die plate 1, a punching die 2, an upper pad 7, and an upper die seat 8. The punching die 2 is embedded in the upper die plate 1, and the upper pad 7 is fixedly mounted on the top surface of the upper die plate 1 by fasteners. The upper die seat 8 is fixedly mounted on the top surface of the upper pad 7 by fasteners. A discharge hole 201 for discharging waste material 301 is provided on the punching die, and a first discharge port 701 communicating with the discharge port 201 is provided on the upper pad 7. A second discharge port 801 communicating with the first discharge port 701 is provided on the upper die seat 8. The lower die assembly comprises a lower die plate 4, a pressing plate 5, a punching punch 6, and a lower die seat 11. The pressing plate 5 can be movably mounted on the lower die plate 4. A pressing hole 401 is provided for the punching punch 6 to pass through the pressing plate 5 upward. The punching punch 6 is installed on the lower template 4 through fasteners and cooperates with the punching die 2. The lower die seat 11 is installed on the bottom surface of the lower template 4 through fasteners. When the upper die assembly and the lower die assembly cooperate with each other, the punching punch 6 passes through the pressing plate 5 and cooperates with the punching die 2 to punch the product 3. The cut waste 301 moves upward after separating from the product 3 and is discharged from the outside of the upper die assembly through the discharge hole 201, the first discharge port 701, and the second discharge port 801 in sequence. While ensuring that the direction of the punching burr of the product 3 is consistent with the direction of the trimming burr, there is no need to flip the product 3 before the punching process, thereby reducing the operating procedures during the processing of the product 3 and improving the production efficiency of the product 3.

[0029] In addition, by adopting the multi-station material picking and reverse punching hole structure of the robot in the above technical solution, there is no need to add two sets of connecting rod robots before and after the punching process, which reduces the company's investment in connecting rod robots and reduces the company's equipment investment costs, which can reduce the production cost of Product 3 to a certain extent.

[0030] Furthermore, the upper mold assembly also includes a guide block 9 for changing the discharge direction of the waste 301, and a discharge trough 10 for allowing the waste 301 to slide out of the outside of the upper mold assembly. Specifically, the guide block 9 is arranged on the top surface of the upper mold base 8 and is located at the discharge end of the second discharge port 801. The discharge trough 10 is arranged on the top surface of the upper mold base 8 and is inclined downward from the center of the upper mold plate 1 to the edge. A guide surface 901 for guiding the waste 301 is provided on the guide block 9. The guide surface 901 is located on the side of the guide block 9 facing the discharge trough 10 and is inclined from bottom to top toward the discharge trough 10. Through the above technical solution, when the waste 301 is discharged upward, its discharge direction is changed by the guide surface 901 of the guide block 9 and falls into the discharge trough 10, so that the waste 301 slides out of the discharge trough 10, thereby realizing the discharge of the waste 301 from the reverse punching hole structure of the multi-station material taking of the robot, which can be understood by those skilled in the art.

[0031] Furthermore, the lower die assembly also includes several groups of reset parts 12 for resetting the pressing plate 5 upward. Specifically, in the present embodiment, the number of the reset parts 12 is preferably twelve groups and they are evenly arranged in a ring shape between the lower die base 11 and the pressing plate 5. The reset parts 12 are preferably pressure springs or buffer rubber. The lower mold plate 4 is provided with a through hole 401 for the reset part 12 to pass through the lower mold plate 4, so that the reset part 12 can be positioned between the lower die base 11 and the pressing plate 5 through the through hole 401. When the upper die assembly and the lower die assembly cooperate with each other, the pressing plate 5 is pressurized and overcomes the elastic force of the reset part 12 to move downward, so that the punching punch 6 extends out of the pressing plate 5 to cooperate with the punching die 2 and punch the product 3. When the upper die assembly and the lower die assembly are separated from each other, the pressing plate 5 is reset upward under the action of the reset part 12, so that the punching punch 6 is retracted into the pressing plate 5, so as to facilitate the unloading of the product 3 from the pressing plate 5. Those skilled in the art can understand this.

[0032] Furthermore, the lower mold assembly also includes a first guide structure. Specifically, in the present embodiment, the first guide structure includes a first guide column 402 arranged on the lower mold plate 4, and a first guide sleeve 501 arranged on the pressure plate 5 and cooperating with the first guide column 402. The number of the first guide columns 402 is preferably four groups and they are extended along the up and down direction of the lower mold assembly. The number of the first guide sleeves 501 corresponds to the first guide columns 402, which is preferably four groups and they are extended along the up and down direction of the lower mold assembly. Through the above technical scheme, the pressure plate 5 is guided to move relative to the lower mold plate 4 along the up and down direction of the lower mold assembly, which can improve the movement stability of the pressure plate 5 to a certain extent, which can be understood by those skilled in the art.

[0033] Furthermore, the punching punch 6 is provided with a positioning portion 601 for positioning and cooperating the product 3 with the punching punch 6. Specifically, in the present embodiment, the unprocessed product 3 is provided with a convex portion which protrudes downward and whose horizontal projection is in the shape of an inverted cone. The horizontal projection shape of the positioning portion 601 is in the shape of an inverted cone and is arranged on the top surface of the punching punch 6. When the upper die assembly and the lower die assembly cooperate with each other and the punching punch 6 moves upward and contacts the product 3, the convex portion of the unprocessed product 3 partially extends into the positioning portion 601, so that the unprocessed product 3 is positioned and cooperated with the punching punch 6, thereby ensuring the punching accuracy of the product 3. Those skilled in the art can understand this.

[0034] Furthermore, a second guide structure is provided between the upper mold assembly and the lower mold assembly. Specifically, in the present embodiment, the second guide structure includes a second guide column 403 provided on the lower mold plate 4, and a second guide sleeve 101 provided on the upper mold plate 1 and cooperating with the second guide column 403. The number of the second guide columns 403 is preferably four groups and they are extended in the up-down direction of the lower mold plate 4. The number of the second guide sleeves 101 corresponds to the second guide columns 403, which are preferably four groups and they are extended in the up-down direction of the upper mold plate 1. Through the above technical scheme, the upper mold assembly is guided to move relative to the lower mold assembly in the up-down direction of the reverse punching hole structure of the multi-station material taking of the robot, which can improve the accuracy of the position of the punching die 2 and the punching punch 6 when they cooperate to a certain extent, which can be understood by those skilled in the art.

[0035] Furthermore, a positioning structure is provided between the upper mold assembly and the lower mold assembly to position the product 3. Specifically, in the present embodiment, the positioning structure includes a positioning protrusion 502 provided on the pressing plate 5, and a positioning recess 102 provided on the upper mold plate 1 and cooperating with the positioning protrusion 502. The horizontal projection shape of the product 3 is semicircular. The horizontal projection shape of the positioning protrusion 502 corresponds to that of the product 3, which is hemispherical and is provided on the top surface of the pressing plate 5. The horizontal projection shape of the positioning recess 102 corresponds to that of the positioning protrusion 502 provided on the bottom surface of the upper mold plate 1. Through the above technical scheme, the product 3 can be positioned on the pressing plate 5, and when the upper mold assembly and the lower mold assembly cooperate with each other, the positioning protrusion 502 and the positioning recess 102 cooperate with each other to avoid displacement of the product 3, thereby ensuring the accuracy of the punching position. Those skilled in the art can understand this.

[0036] See also Figure 5-7 When the multi-station material picking and reverse punching hole structure of the manipulator is working, first, the product 3 is placed on the pressure plate 5, and then the stamping equipment is started, the upper mold assembly moves downward, and the upper mold plate 1 cooperates with the pressure plate 5 to press the product 3 tightly on the multi-station material picking and reverse punching hole structure of the manipulator. Then, the upper mold assembly continues to move downward, and the pressure plate 5 moves downward under pressure. The punching punch moves upward relative to the pressure plate 5 and cooperates with the punching die to punch the product 3. The waste material 301 separated from the product 3 is moved upward by the pressure of the punching punch and discharged out of the upper mold assembly. After the processing is completed, the upper mold assembly is reset upward, and the pressure plate 5 is reset upward through the reset component 12. Finally, the processed product 3 is taken out.
