[0079] What needs to be understood is that the material is fed by a feeding assembly, that is, it is evenly moved from one direction to another, so that with the reciprocating stamping of the upper mold assembly 10, the stamping operations of various structures such as trimming, punching and bending mentioned above are completed in sequence.

[0080] Preferably, in an embodiment of the present invention, the trimming assembly includes a trimming punch 1031 and a trimming insert 2031 .

[0081] The tail end of the trimming punch 1031 is connected to the upper clamping plate 103 , and the head end is inserted into the stop plate 104 and the upper stripping plate 105 .

[0082] The trimming insert 2031 is disposed on the lower template 203 to cooperate with the trimming punch 1031 to trim the material.

[0083] In this way, since the front end of the trimming punch 1031 is inserted into the stop plate 104 and the upper stripping plate 105, when the punch press drives the upper die assembly 10 to move downward, the upper stripping plate 105 and the lower die plate 203 clamp the material, and the punch press continues to drive the upper die assembly 10 to move downward, and the upper die spring 1051 of the upper stripping plate 105 is compressed, that is, the upper pad 102 and the trimming punch 1031 on the upper pad 102 can continue to move downward and punch on the material to cooperate with the trimming insert 2031 to perform trimming operations on the material.

[0084] Preferably, in an embodiment of the present utility model, the punching assembly includes a punching punch 1032 and a salad punch 1033 .

[0086] The rear end of the salad punch 1033 is arranged on the upper clamping plate 103, and the front end is penetrated through the stop plate 104 and the upper stripping plate 105 to punch salad holes in the material.

[0087] In this way, since the head ends of the punching punch 1032 and the salad punch 1033 are both inserted into the stop plate 104 and the upper stripping plate 105, when the punch press drives the upper die assembly 10 to move downward, the upper stripping plate 105 and the lower die plate 203 clamp the material, and the punch press continues to drive the upper die assembly 10 to move downward, and the upper die spring 1051 of the upper stripping plate 105 is compressed, that is, the upper pad 102 and the punching punch 1032 and the salad punch 1033 on the upper pad 102 can continue to move downward and punch on the material to cooperate with the corresponding punch insert 2032 to punch holes and punch salad holes in the material.

[0088] Preferably, in an embodiment of the present invention, the bending assembly includes a downward bending punch 1034 and an upward bending punch 2034 .

[0089] The tail end of the downward bending punch 1034 is arranged on the upper clamping plate 103, and the head end is passed through the stop plate 104 and the upper stripping plate 105. The lower template 203 is provided with a bending insert 2033 to cooperate with the downward bending punch 1034 to bend the material downward.

[0090] The upward bending punch 2034 is arranged on the lower template 203, and an upward bending pressure block 2035 is provided on one side of the upward bending punch 2034. A slider 1035 is provided on the upper stripping plate 105. The slider 1035 and the upward bending pressure block 2035 are arranged relative to each other to cooperate with the upward bending pressure block 2035 to clamp the material, so that the upward bending punch 2034 bends the material upward.

[0091] In this way, since the tail end of the downward bending punch 1034 is arranged on the upper clamping plate 103, and the head end is passed through the stop plate 104 and the upper stripping plate 105, the lower template 203 is provided with a bending insert 2033. In this way, when the punch press drives the upper mold assembly 10 to move downward, the upper stripping plate 105 and the lower template 203 clamp the material, and the punch press continues to drive the upper mold assembly 10 to move downward, the upper mold spring 1051 of the upper stripping plate 105 is compressed, that is, the upper pad 102 and the downward bending punch 1034 on the upper pad 102 can continue to move downward and punch on the material to cooperate with the corresponding bending insert 2033 to realize downward bending of the workpiece.

[0092] Correspondingly, in the same process, when the punch press drives the upper die assembly 10 to move downward, the upper stripping plate 105 and the lower die plate 203 clamp the material, and the punch press continues to drive the upper die assembly 10 to move downward, and the upper die spring 1051 of the upper stripping plate 105 is compressed. At this time, the upward bending pressure block 2035 and the slider 1035 clamp the material, and the upward bending punch 2034 can bend the workpiece upward.

[0093] Preferably, in an embodiment of the present invention, a ejector pin 20331 is inserted into the bending insert 2033 , and a first spring 20332 is connected to the tail end of the ejector pin 20331 to separate the material from the lower template 203 .

[0094] It should be noted that when the downward bending punch 1034 bends the part, the ejector pin 20331 is compressed and retracted into the lower mold plate 203, and the first spring 20332 is in a contracted state. In this way, when the downward bending punch 1034 completes bending the material, the punch press drives the upper mold assembly 10 to rise, and the ejector pin 20331 can rise under the elastic force of the first spring 20332 to separate the bent part of the material from the lower mold assembly 20.

[0095] Preferably, in one embodiment of the utility model, a plurality of guide columns 1036 are provided on the upper pad 102, and the lower ends of the plurality of guide columns 1036 are passed through the stop plate 104 and the upper stripping plate 105, and a plurality of guide sleeves 2036 are provided on the lower mold base 201, and the plurality of guide sleeves 2036 are opposite to the plurality of guide columns 1036 one by one, and the upper ends of the plurality of guide sleeves 2036 are passed through the lower pad 202 and the lower mold plate 203, and when the upper mold assembly 10 is close to the lower mold assembly 20, the plurality of guide columns 1036 are inserted into the guide sleeves 2036 one by one.

[0096] In this way, when the punch press drives the upper die assembly 10 to move downward, the guide column 1036 can be inserted into the guide sleeve 2036 to play a guiding role, so that the upper die assembly 10 and the lower die assembly 20 are accurately aligned.

[0097] Preferably, in one embodiment of the present invention, a floating pin 2037 is further included. The floating pin 2037 is inserted into the lower mold plate 203 and a second spring 20371 is connected to the tail of the floating pin 2037 to restore the position of the material.

[0098] It can be understood that when the upper mold assembly 10 and the lower mold assembly 20 are closed, the lifting pin 2037 is compressed and retracted into the lower mold plate 203. After the stamping is completed, the elastic force of the second spring 20371 can drive the lifting pin 2037 to rise to lift the material, help the material to reset, and facilitate the subsequent movement of the material.

[0099] Advantageously, in one embodiment of the present invention, a limiting column 2038 is provided on the lower mold plate 203 , and the limiting column 2038 protrudes from the upper surface of the lower mold plate 203 to limit the downward movement stroke of the upper mold assembly 10 .

[0100] In this way, by providing the limiting column 2038 on the lower mold plate 203, the formation of the upper mold assembly 10 can be effectively limited to avoid damage to materials or products caused by overpressure.

[0101] Preferably, in one embodiment of the utility model, a packing punch 1037 is provided on the upper clamping plate 103, and the lower end of the packing punch 1037 is passed through the stop plate 104 and the upper stripping plate 105, and a packing insert 1038 is provided on the lower template 203, and the packing insert 1038 and the packing punch 1037 are opposite to each other in upper and lower directions and are used to punch out convex bulges on the material.

[0102] In this way, when the upper die assembly 10 moves downward, the packing punch 1037 and the packing insert 1038 cooperate with each other to punch out a bulge on the material.

[0103] Preferably, in an embodiment of the present invention, the lower template 203 is further provided with a burr remover 2039 for removing burrs around the material.

[0104] In this way, when the upper mold assembly 10 moves downward, the burr remover 2039 can remove the burrs around the material.

[0105] Preferably, in another embodiment of the present application, the upper release plate 105 is also provided with a positioning pin, and a corresponding positioning hole is provided on the material. When the punch press moves downward, the positioning pillow is inserted into the positioning hole on the material to fix the position of the material.

[0106] Here’s how this application works:

[0107] When the punch press moves downward, the guide pin in the upper clamping plate 103 is inserted into the guide sleeve 2036 hole in the lower template 203 to align the upper and lower molds. The punch press continues to move downward, and the positioning pin of the upper stripping plate 105 is inserted into the positioning hole in the material to fix the position of the material. The upper stripping plate 105 contacts the material and contacts the material with the upward bending pressing block 2035 as the punch press continues to move downward. The upward bending pressing block 2035 and the upper stripping plate 105 continue to press the material by the downward force of the punch press and the upward bending punch 2034 to complete the upward bending process.

[0108] Under the action of the downward force of the punch press, the material contacts the lower template 203. At this time, the upper stripper plate 105 has already moved down to its position. The upper splint 103 needs to continue to move down under the action of the punch press. The packing punch 1037, the punching punch 1032, the salad punch 1033, the bending assembly, and the trimming assembly in the upper splint 103 complete the corresponding processes during the downward movement of the upper splint 103 until the upper splint 103 is in complete contact with the stop plate without a gap, and the downward movement ends.

[0109] When the process is completed, the punch press starts to rise and drives the upper die assembly. The punching assembly, bending assembly and trimming assembly in the upper clamp plate 103 are pulled out from the lower die plate 203 under the pressure of the upper die spring 1051. The upper clamp plate 103 moves up to a certain height and drives the upper stripping plate 105 to move up. The material of the upper stripping plate 105 is removed from the mold by the ejector pin 20331. As the punch press continues to move upward, the material returns to its original state along with the floating pin 2037 of the lower die plate 203 and completes a punch under the action of the forward propulsion of the feeder. After multiple process steps (i.e., the material is pushed forward for multiple punching), the production of the entire product is finally completed.
