DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] See also Figure 1 , Figure 2 as well as Figure 3 The present embodiment provides a metal sheet stamping die, comprising a stamping table 10, a first driving assembly 20, a partition plate 30, a punch cylinder 40 and a second driving assembly 50. A U-shaped bracket plate 102 is fixedly arranged on the upper part of the stamping table 10. The first driving assembly 20 is installed on the stamping table 10, and is used to drive a plurality of stacked metal sheets to move toward the inner side of the U-shaped bracket plate 102. The punch cylinder 40 is arranged on the inner side of the U-shaped bracket plate 102. The second driving assembly 50 is installed on the inner top of the U-shaped bracket plate 102, and is used to drive the punch cylinder 40 to move downward. The partition plates 30 are provided with a plurality of groups, and a plurality of the partition plates 30 are vertically spaced and distributed below the punch cylinder 40. Each group of the partition plates 30 is provided with a through hole 301 adapted to the punch cylinder 40. When a plurality of stacked metal sheets move toward the inner side of the U-shaped bracket plate 102, the plurality of the partition plates 30 are used to separate the plurality of stacked metal sheets into a plurality of layers.

[0034] When it is necessary to punch a number of metal sheets, the metal sheets can be stacked on the upper part of the punching table 10, and then the first driving component 20 is used to drive the stacked metal sheets to move toward the inner side of the U-shaped bracket plate 102. During this process, a number of partition plates 30 are embedded in the inner layers of the metal sheets to separate the metal sheets into a number of layers. Then, the second driving component 50 drives the punch cylinder 40 to move downward. When the punch cylinder 40 moves downward, it acts on the several layers of metal sheets and passes through the through hole 301 on the partition plate 30, thereby realizing the punching processing of the metal sheets.

[0035] See also Figure 1 as well as Figure 4 In one embodiment, a vertically distributed guide rod 103 is fixedly provided inside the U-shaped bracket plate 102, and a first sleeve 302 is fixedly provided on the side walls of several of the partition plates 30. The first sleeve 302 is sleeved on the outside of the guide rod 103 and can slide up and down along the guide rod 103.

[0036] When the first driving component 20 drives the plurality of stacked metal sheets to move toward the inner side of the U-shaped bracket plate 102, the plurality of partition plates 30 can be inserted into the plurality of metal sheets from the gaps between the plurality of metal sheets, thereby separating the plurality of metal sheets into a plurality of layers, and each partition plate 30 has at least one or a small number of metal sheets on the upper part. When the second driving component 50 drives the punch 40 to move downward, the lower end of the punch 40 acts in advance on the metal sheet on the upper part of the uppermost partition plate 30. At this time, the metal sheet on the upper part of the uppermost partition plate 30 can be punched through the extrusion and shearing action between the lower end of the punch 40 and the through hole 301, and the punched metal sheet enters the interior of the punch 40. When the punch After the punch 40 passes through the through hole 301 on the uppermost partition plate 30, the lower end of the punch cylinder 40 acts on the metal sheet on the upper part of the second upper partition plate 30, and then punches and shears the corresponding metal sheet again, and then the punch cylinder 40 passes through the through hole 301 on the second upper partition plate 30 again, and repeats this reciprocating cycle to complete the punching process of several stacked metal sheets; when the several stacked metal sheets move toward the inner side of the U-shaped bracket plate 102 and the several partition plates 30 are inserted into between the several metal sheets from the gaps between the several metal sheets, since the heights of the several metal sheets will change, the several partition plates 30 can drive the first sleeve 302 on the side wall thereof to slide adaptively along the outside of the guide rod 103.

[0037] See also Figure 5 In one embodiment, one side of the partition plate 30 is provided with a conical cutting edge, so that when the first driving assembly 20 drives a plurality of stacked metal sheets to move into the U-shaped bracket plate 102, the conical cutting edge on one side of the partition plate 30 can accurately cut into between two adjacent metal sheets, thereby achieving smooth stratification of the plurality of metal sheets.

[0038] See also Figure 1 In one embodiment, the second driving assembly 50 includes a hydraulic cylinder 501 and a support plate 502, the hydraulic cylinder 501 is fixedly mounted on the inner top wall of the U-shaped bracket plate 102, the support plate 502 is fixedly arranged at the output end of the hydraulic cylinder 501, and the punch 40 is fixedly arranged at the bottom of the support plate 502.

[0039] After the plurality of partition plates 30 separate the plurality of stacked metal sheets into a plurality of layers, the hydraulic cylinder 501 drives the support plate 502 to move downward, thereby driving the punch cylinder 40 to move downward. When the punch cylinder 40 moves downward, its lower end acts on the plurality of metal sheets and cooperates with the partition plates 30 to punch holes in the plurality of metal sheets.

[0040] See also Figure 1 as well as Figure 2In one embodiment, a second sleeve 503 is fixedly provided on the side wall of the support plate 502, and the lower end of the second sleeve 503 is connected to a third sleeve 505 through a second elastic member 504. The second sleeve 503 and the third sleeve 505 are both movably sleeved on the outside of the guide rod 103, and the second elastic member 504 is used to provide elastic support for the third sleeve 505.

[0041] When the hydraulic cylinder 501 drives the support plate 502 and the punch 40 to move downward, the support plate 502 drives the second sleeve 503 to move downward along the outside of the guide rod 103, and the second sleeve 503 drives the third sleeve 505 to move downward along the outside of the guide rod 103 synchronously through the second elastic member 504. When the third sleeve 505 moves downward, it acts on the first sleeve 302 on the side wall of the uppermost partition plate 30, thereby applying downward pressure to the first sleeve 302. When the first sleeve 302 is pressurized, it transfers the pressure to the several first sleeves 302 below, thereby pressing the several partition plates 30. After the several partition plates 30 are pressed, the metal sheets between the two adjacent groups of partition plates 30 are pressed synchronously. In this way, when the punch 40 moves downward to punch the metal sheet, the stability of the metal sheet can be improved, thereby improving the punching effect.

[0042] See also Figure 3 In one embodiment, a pressure plate 402 is movably provided inside the punch cylinder 40 , and the upper portion of the pressure plate 402 is connected to the inner top wall of the punch cylinder 40 through a first elastic member 401 , and the first elastic member 401 is used to provide elastic support for the pressure plate 402 .

[0043] As the lower end of the punch cylinder 40 punches holes in a number of metal sheets, the punched metal sheets are pressed into the interior of the punch cylinder 40, thereby driving the pressing plate 402 to move upward along the interior of the punch cylinder 40, and the first elastic member 401 is continuously compressed. When the punching of the lowest metal sheet is completed, the first elastic member 401 pushes the pressing plate 402 to move downward along the interior of the punch cylinder 40, thereby pushing the metal sheets collected in the punch cylinder 40 out from the lower end of the punch cylinder 40, completing the automatic unloading of the metal sheets.

[0044] See also Figure 2 In one embodiment, a slide groove 104 is provided on the stamping table 10, and the first driving component 20 includes a push rod 201, a motor 202 and a screw rod 203. The motor 202 is fixedly installed at the bottom of the stamping table 10, one end of the push rod 201 extends to the top of the stamping table 10, and the other end extends from the slide groove 104 to the bottom of the stamping table 10. One end of the screw rod 203 is connected to the output end of the motor 202, and the other end passes through the push rod 201 and is threadedly matched with the push rod 201.

[0045] After stacking a number of metal sheets on the top of the stamping table 10, start the motor 202, which drives the screw rod 203 to rotate. The screw rod 203 and the push rod 201 cooperate with each other through the threaded joint action, thereby driving the push rod 201 to move along the length direction of the screw rod 203. At the same time, the push rod 201 slides inside the slide groove 104, thereby pushing the several metal sheets so that the several metal sheets move toward the inside of the U-shaped bracket plate 102.

[0046] See also Figure 1 In one embodiment, a rolling support assembly 60 is also provided on the upper portion of the stamping table 10, and the rolling support assembly 60 is used to provide rolling support for a plurality of stacked metal sheets, thereby ensuring that the first driving assembly 20 can smoothly drive the plurality of metal sheets to move toward the inner side of the U-shaped bracket plate 102.

[0047] See also Figure 4 In one embodiment, the rolling support assembly 60 includes a side roller 601, a first support rod 602, a second support rod 603 and a bottom roller 604. The first support rod 602 is fixedly arranged on the upper part of the stamping table 10 and is vertically distributed. The side roller 601 is rotatably mounted on the outside of the first support rod 602. The second support rod 603 is fixedly arranged on the side wall of the first support rod 601 and is horizontally distributed. The bottom roller 604 is rotatably mounted on the outside of the second support rod 603.

[0048] After stacking a number of metal sheets on the top of the stamping table 10, the bottom roller 604 can provide rolling support for the metal sheets from the bottom edges of the metal sheets, and the side roller 601 can provide rolling support for the metal sheets from the sides of the metal sheets, so that when the motor 202 drives the push rod 201 to move and then push the metal sheets, the bottom roller 604 adaptively rotates compared to the second support rod 603, and the side roller 601 adaptively rotates compared to the first support rod 602, so that the metal sheets can move smoothly toward the inside of the U-shaped bracket plate 102.

[0049] In one embodiment, the first elastic member 401 and the second elastic member 504 may be springs or metal springs, which are not limited here.

[0050] See also Figure 1 In one embodiment, a plurality of legs 101 are fixedly provided on the bottom edge of the stamping table 10 .

[0051] In an embodiment of the present invention, when it is necessary to punch a plurality of metal sheets, the plurality of metal sheets can be stacked on the upper part of the punching table 10, and then the first driving assembly 20 is used to drive the stacked plurality of metal sheets to move toward the inner side of the U-shaped bracket plate 102. During this process, a plurality of partition plates 30 are embedded in the inner layers of the plurality of metal sheets to separate the plurality of metal sheets into a plurality of layers. Subsequently, the second driving assembly 50 drives the punch cylinder 40 to move downward.
