DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-12 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Reference Figure 1-Figure 5 A swing compound blanking die includes an upper die 1, a lower die 2, a plurality of guide pillars 3 and a plurality of guide sleeves 4, wherein the upper die 1 includes an upper die seat 5 and an upper die fixing seat 6, and the lower die 2 includes a lower die seat 7 and a lower die fixing seat 8, the upper die fixing seat 6 and the plurality of guide pillars 3 are fixedly arranged at the bottom end of the upper die seat 5, the lower die fixing seat 8 and the plurality of guide sleeves 4 are fixedly arranged on the lower die seat 7, and the plurality of guide pillars 3 are inserted into the inner part of the guide sleeve 4 to realize the lifting connection. An upper punching die 66 is fixedly arranged at the bottom end of the upper die fixing seat 6, and the upper punching die 66 includes a hole punch 63 and a compound die 65; correspondingly, a lower punching die 87 is fixedly arranged on the lower die fixing seat 8, and the lower punching die 87 includes a hole die 81 and a compound punch 82. Under the action of the deflection machine, the large plate deflects back and forth and left and right between the upper punching die 66 and the lower punching die 87; as the upper punching die 66 and the lower punching die 87 are engaged with each other, a number of parts are punched out from the surface of the large plate.

[0037] Refer to 4. Figure 5 and Figure 6 A positioning pin 61 is provided at the bottom center of the upper die fixing seat 6. According to the size of the inner hole of the part to be punched, a corresponding hole punch 63 is selected and sleeved on the periphery of the positioning pin 61. A punch pad 62 is provided between the hole punch 63 and the upper die fixing seat 6, and the hole punch 63 and the upper die fixing seat 6 are fixed by bolts. The setting of the positioning pin 61 facilitates the positioning and installation of the hole punch 63. A stripper plate 64 is also provided at the bottom end of the upper die fixing seat 6. The stripper plate 64 and the composite die 65 are both annular. Lifting columns are slidably penetrated in the upper die seat 5 and the upper die fixing seat 6. The stripper plate 64 is sleeved on the periphery of the hole punch 63 and fixedly connected between the lifting columns, so as to realize the sliding lifting connection between the stripper plate 64 and the upper die fixing seat 6. Finally, the composite die 65 is sleeved on the periphery of the stripper plate 64 and fixedly connected with the upper die fixing seat 6 by bolts. The blade surface of the composite die 65 is designed to be wavy, thereby reducing the tonnage of the hydraulic press and also reducing the vibration and noise after the die is closed.

[0038] Reference Figure 3 and Figure 7 The hole die 81 and the compound punch 82 are both annular, the hole die 81 is set at the center of the lower die fixing seat 8, and the compound punch 82 is set at the periphery of the hole die 81 and fixed between the lower die fixing seat 8. An upper knife seat 51 is fixedly set at the bottom end of one side of the upper die seat 5, and a lower knife seat 71 is fixedly set on one side of the lower die seat 7 correspondingly, an upper cutter 52 is fixedly set on the upper knife seat 51 by bolt locking, and a lower cutter 72 is fixedly set on the lower knife seat 71 by bolt locking, the upper cutter 52 and the lower cutter 72 are kept staggered, and the four edges of the upper cutter 52 and the lower cutter 72 are all set as cutting edges. Since the upper cutter 52 and the upper cutter seat 51, and the lower cutter 72 and the lower cutter seat 71 are all detachably installed, the upper cutter 52 and the lower cutter 72 can be installed and used by changing the surface, thereby improving the utilization rate of the props.

[0039] Reference Figure 3 , Figure 4 and Figure 8The large plate is placed between the upper die 1 and the lower die 2. The upper die 1 moves downward so that the upper die 1 and the lower die 2 are matched with each other. The compound punch 82 punches out the part in the large plate. The compound punch 82 is inserted into the compound die 65 so that the part is embedded in the compound die 65. At the same time, the hole punch 63 punches the center hole on the surface of the part. After the punching is completed, the hole punch 63 is inserted into the center hole on the surface of the part. When punching a large plate, in order to avoid damage to the large plate, a ejector plate 83 is provided on the lower die seat 7. The ejector plate 83 is annular and sleeved on the periphery of the composite punch 82. A plurality of elastic components 84 are provided between the ejector plate 83 and the lower die seat 7. The elastic components 84 include ejector rods 841 and air cushion ejector plates 842. The air cushion ejector plates 842 are fixedly provided on the lower die seat 7. Each ejector rod 841 is vertically and fixedly provided on the air cushion ejector plate 842. One end of each ejector rod 841 is away from the air cushion ejector plate 842 and is fixed to the ejector plate 83 to support the ejector plate 83. When the large plate is laid on the ejector plate 83 and the upper die 1 and the lower die 2 are combined to punch the large plate, the ejector plate will compress the air cushion ejector plate 842 through the ejector rods 841. The setting of the elastic component 84 has a certain buffering effect on the ejector plate 83, so that the ejector plate 83 has a certain activity space.

[0040] Reference Figure 1 and Figure 7 After the parts are punched out on the surface of the large plate, a clearance hole is punched out on the surface of the large plate, and then the large plate is deflected. After the large plate is deflected, the position of the clearance hole corresponds to the position of the guide column 3. The guide column 3 is fixedly set on the upper die seat 5. There is no need to install the guide column 3 at the edge of the plate during the deflection to make way for the plate, so as to avoid the interference of the guide column 3 on the deflection of the large plate, thereby greatly saving the size of the mold space and the complexity of the structure. Correspondingly, a number of guide sleeves 4 are set on the lower die seat 7. After the guide sleeves 4 are set, their top ends will not be higher than the compound punch 82, thereby realizing the deflection and compound blanking of the large plate.

[0041] Then, the upper die 1 and the lower die 2 are closed to continue punching out parts on the surface of the large plate. The large plate is swung left and right twice to completely cut off the scraps formed by the punched parts. A sliding plate 74 is obliquely arranged on one side of the lower knife seat 71 of the lower die seat 7. For this purpose, fixed blocks 73 are fixedly arranged on both sides of the lower knife seat 71, and the upper surface of the fixed block 73 is set as an inclined surface. One side of the sliding plate 74 is abutted against the inclined surface of the fixed block 73, and the sliding plate 74 and the fixed block 73 are fixed by bolts. After the scraps on the large plate are cut off, the cut scraps can slide along the sliding plate 74 to the conveyor belt, thereby increasing the labor cost of taking the scraps.

[0042] The scraps formed by punching the large plate are cut by the upper cutter 52 and the lower cutter 72. In order to avoid the scraps from tilting up when cutting the scraps, a plurality of connecting rods 53 are fixedly arranged on one side of the upper die holder 5 where the upper cutter holder 51 is provided. The plurality of connecting rods 53 are parallel to each other and maintain a vertical state. A pressing rod 54 is fixedly arranged at one end of the plurality of connecting rods 53 away from the upper die holder 5, and the pressing rod 54 is kept horizontally arranged and fixed between the connecting rods 53. The setting of the pressing rod 54 plays a role in protecting the upper cutter 52 and the lower cutter 72 by pressing the scraps to avoid the scraps from tilting up. When cutting the scraps, in order to avoid the large plate from tilting. A support rod 85 is fixedly arranged on one side of the top plate 83 close to the upper cutter 52, and the support rod 85 is kept in a horizontal state and supports the scraps. At the same time, when the large plate is swaying, the scraps slide along the support rod 85, thereby preventing the large plate from being scratched. In addition, three nylon blocks 86 are arranged on the ejector plate 83, and the three nylon blocks 86 surround the composite punch 82 on three sides. The arrangement of the nylon blocks 86 further prevents the large plate from being scratched during the swaying process.

[0043] Reference Figure 9-12 The specific implementation principle of the embodiment of the present application is as follows: when it is necessary to use the wheel spoke part eccentric composite blanking die to punch and form parts in a large plate, the large plate is inserted between the upper die 1 and the lower die 2, and the large plate can be eccentric between the upper die 1 and the lower die 2. According to the specifications of the parts to be punched and formed, the corresponding hole punch 63 and the composite die 65 are selected and installed on the upper die seat 5, and the hole die 81 and the composite punch 82 are fixedly installed on the lower die seat 7. When the hole punch 63 is installed, it is sleeved on the periphery of the positioning pin 61 to achieve positioning. As the upper die 1 and the lower die 2 are clamped with each other, the composite punch 82 is inserted into the composite die 65, so that the part formed by punching is embedded in the composite die 65. At the same time, the hole punch 63 is inserted into the hole die 81, and a middle hole is punched on the surface of the part, so that the part is embedded in the composite die 65, so that the part is punched out at the middle position of one side of the large plate, and a clearance hole is formed after the part is punched out of the large plate. As the upper mold 1 and the lower mold 2 separate from each other, the large plate swings on the nylon block 86, and a plurality of guide pillars 3 are arranged on the upper mold base 5. There is no need to install the guide pillars 3 at the outermost position of the plate during the swing to make way for the large plate, which greatly saves the mold space size and structural complexity.

[0044] While the large plate is deflecting, the power rod of the punching drives the unloading plate 64 to eject the parts embedded in the composite die 65 to complete the unloading. When the parts are punched out of the surface of the large plate again, the clearance holes formed by the previous punching of the surface of the large plate correspond to the position of the guide column 3, and the upper and lower molds 2 are closed again to punch out the parts again. At the same time, the upper mold 1 and the lower mold 2 are closed, so that the upper cutter 52 and the lower cutter 72 cut the scraps formed by the punching of the large plate parts, and the cut scraps slide along the sliding plate 74 to the conveyor belt for transportation. The pressure rod 54 prevents the scraps from warping up when cutting the scraps, thereby protecting the upper cutter 52 and the lower cutter 72. The setting of the support rod 85 prevents the large plate from tilting during the cutting of the scraps. The wheel spoke part sway composite blanking die is used to punch out parts on the surface of the large plate. Since the large plate can sway, the guide column 3 will not interfere with the sway of the large plate, thereby greatly improving the material utilization rate of the large plate. In addition, other employees are not required to take and place parts and take and place scraps, reducing labor costs.

[0045] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
