Moreover, existing trimming structures have low production efficiency and cannot meet the demands of large-scale production. Therefore, there is an urgent need for a stamping trimming structure that can improve trimming precision, reduce stamped housing deformation, and increase production efficiency for material processing.

[0028] The following is combined Figures 1 to 6 The embodiments of this utility model are described below, wherein... Figure 3 , Figure 4 The cut-off position is as follows Figure 6 As shown at point A in the middle; Figure 1 , Figure 2 , Figure 5 The cut-off position is as follows Figure 6 As shown at point B in the middle.
[0029] This application provides a stamping edge trimming structure including a first stripping assembly, a contour fixing block 103, a pressure block 104, a shearing punch 105, and a second stripping assembly; the first stripping assembly and the contour fixing block 103 are connected to the frame, and the pressure block 104, the shearing punch 105, and the second stripping assembly are connected to the stamping head; the pressure block 104 is provided with a processing groove, and the contour fixing block 103 is provided with a processing protrusion, the processing groove and the processing protrusion cooperate to form a first processing area, the first processing area is used to stamp the material to bend the edge of the material;
[0030] The shearing punch 105 is located above the feed end of the first processing area and is used to cut the edge of the material. The first stripping assembly includes a first stripping block 102, which is used to remove the processed material from the processing protrusion. The second stripping assembly is used to remove the processed material from the processing groove. The top of the first stripping assembly is provided with a positioning groove 302 for accommodating the material.
[0031] In this invention, the material is stamped in a first processing area formed between the pressure block 104 mounted on the stamping head and the contour fixing block 103 mounted on the frame. This causes the conveyed metal sheet to bend at the outer edge. Before the material is removed after stamping and bending, the shearing punch 105 cuts the stamped material, completely separating it from the subsequent metal sheet. At this time, the first processing area formed by the pressure block 104 and the contour fixing block 103 clamps the material. While the material is clamped, the shearing punch 105 cuts the material in a fixed state. This process, where the material is first shaped and then cut in a fixed state, results in a more reliable shape than the traditional method of cutting the material before stamping, avoiding edge deformation caused by stamping after cutting.
[0032] like Figure 1As shown, during processing, the punch head drives the second stripping component, the pressing block 104, and the shearing punch 105 provided in this utility model to move upward together; the first stripping component fixed on the frame pushes the first stripping block 102 to move upward, at which time the automatic feeder of the punch press conveys the material (metal coil) into the positioning groove 302, and the material enters the first processing area along the positioning groove 302.
[0033] like Figure 2 As shown, during processing, the stamping head drives the pressure block 104 to move downward through the second stripping assembly. The first processing area formed by the processing groove on the pressure block 104 and the processing protrusion on the contour fixing block 103 stamps the material. At this time, the first stripping block 102 is squeezed and moves downward to compress the first stripping assembly.
[0034] like Figure 3 As shown, during the processing, the punch head drives the pressure block 104 to move downwards and together with the contour fixing block 103 to form the first processing area, thereby stamping the material. When the pressure block 104 clamps the material with the contour fixing block 103, the punch head pushes the shearing punch 105 downwards to cut the edge of the clamped material.
[0035] like Figure 4 As shown, during the processing, after the edge of the clamped material is cut by the shearing punch 105, the punch head moves upward and drives the second stripping component, the shearing punch 105, and the pressure block 104 to move upward together. At this time, because the pressure block 104 moves upward, it no longer applies pressure to the first stripping block 102. The first stripping block 102 moves upward under the push of the first stripping component, pushing the processed material out of the contour fixing block 103. At this time, the processed material is embedded in the processing groove of the pressure block 104 and rises together with the pressure block 104.
[0036] like Figure 5 As shown, during the processing, when the processed material embedded in the processing groove rises together with the pressure block 104, as the height gradually increases, the pressure block 104 disengages from the first stripping block 102, and then the second stripping component pushes the processed material out of the processing groove.
[0037] The first stripping block 102 is provided with a first through groove for receiving the contour fixing block 103, and the edge of the top of the first through groove is used to push the processed material out of the first processing protrusion.
[0038] During processing, the pressing block 104 moves toward the contour fixing block 103 and applies a pushing force to the first unloading block 102, thereby causing the first unloading component to contract and acquire internal potential energy. After processing is completed, when the pressing block 104 is reset, the potential energy inside the first unloading component can be released, pushing the first unloading block to push the material out of the processing area, thereby allowing the material to detach from the processing protrusion.
[0039] The first stripping block 102 includes a first segment and a second segment. The first segment is provided with a first groove, and the second segment is provided with a second groove. The first groove and the second groove are arranged facing each other, and the first groove and the second groove together form a positioning groove 302 for accommodating materials.
[0040] like Figure 1 As shown, during processing, the feeding device continuously feeds materials into the positioning groove 302 and continuously conveys them. The positioning groove 302 is used to position the conveyed materials in the plane to be processed. The openings of the first groove and the second groove are opposite to each other and can accommodate the materials to be processed. The materials pass through them, so that the materials will not be deviated during subsequent stamping processing, thus ensuring the yield rate during the processing.
[0041] The first stripping assembly also includes a first stripping push rod 101 and a first spring 201. The first spring 201 is used to push the first stripping block 102 toward the pressing block 104 via the first stripping push rod 101.
[0042] The first spring 201 is mounted on the frame. The first spring 201 pushes the first stripping rod 101 to strip the material. The structure is simple and the performance is reliable.
[0043] The top end of the first stripping rod 101 is fixedly connected to the first stripping block 102, the bottom end of the first stripping rod 101 is fixedly connected to the top end of the first spring 201, and the bottom end of the first spring 201 is fixedly connected to the frame.
[0044] By installing a first spring 201 at the bottom end of the first stripping rod 101, elastic drive is achieved, which can provide buffering during processing. It can also transmit the pressure applied to the first stripping block 102 when the pressure block 104 is driven by the punch head to the first spring 201, causing the first spring 201 to contract. When the subsequent punch head drives the pressure block 104 to reset and disengage, the first spring 201 releases its elastic force, thereby pushing the first stripping block 102 to move upward for stripping.
[0045] The second stripping assembly includes a second spring 202, a second stripping push rod 107, and a second stripping block 106. The top end of the second spring 202 is connected to the punch head, the bottom end of the second spring 202 is connected to the top end of the second stripping push rod 107, and the bottom end of the second stripping push rod 107 is connected to the top end of the second stripping block 106.
[0046] The second unloading component passes through the pressure block 104 from above. When processing is completed, the processed metal material will adhere to the pressure block 104 and rise together with the pressure block 104. Therefore, it is necessary to push out the material in the processing groove of the pressure block 104 by setting the second unloading component to pass through the pressure block 104.
[0047] The pressing block 104 is provided with a second through groove for accommodating the second unloading block 106, which moves linearly along the second through groove. The bottom end of the second unloading block 106 extends out of the processing groove and pushes the material out of the processing groove. The linear movement of the second unloading block 106 through the second through groove of the pressing block 104 can keep the unloading process as stable as possible and avoid quality problems in the final unloading stage.
[0048] The shearing punch 105 is slidably connected to the second stripping rod 107 via a connecting block. The connecting block ensures the shearing punch 105 maintains a relatively stable position, preventing slippage during processing. Simultaneously, during the downward pressing of the punch head, the sliding connection between the shearing punch 105 and the second stripping rod 107 allows for smooth vertical linear movement, reducing processing errors. Two sets of first stripping components, respectively connected to the bottom of the first and second segments of the first stripping block 102, enhance the stripping force of both segments, improving both reliability and stripping efficiency.
