[0014] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:
[0015] (1) The utility model provides a multi-sided folding edge stamping forming device with a simple structure and easy use. The device reduces the number of molds and manufacturing time, greatly reduces the mold development cost, and shortens the parts production cycle. It can easily and quickly produce multi-sided bent sheet metal parts, thereby improving production efficiency. During processing, the spring piece, under the action of the upper module, drives the folded edge of the sheet metal part to be tilted toward the inner side of the lower module in advance at a certain angle. In this way, when the upper module approaches the lower module for pressing, the folded edge can continue to bend toward the inner side of the lower module until it is flattened. During the whole process, multiple folded edges can be bent at the same time at one time, with extremely high production efficiency. It can also ensure that the flatness of each folded edge is more uniform, thereby improving product quality.
[0016] (2) In the present technical solution, the spring piece abuts against and presses against the sheet metal part to be compressed and deformed, and moves downward along with the upper module to be located on the outer side of the lower module. In this way, the spring piece will not interfere with the flattening action of the upper module and the lower module, thereby achieving an avoidance effect and preventing hidden dangers during the processing process.
[0017] (3) In the present technical solution, the upper module moves upward relative to the lower module, and the locking member slides a certain distance in the sliding hole for buffering first, so that the spring piece releases a certain clamping force relative to the sheet metal on the lower module, and then drives the spring piece away from the upper working surface of the lower module, which can effectively prevent the lower module and the sheet metal from generating continuous friction noise.
[0018] (4) There are at least two sliding holes and locking pieces on the spring sheet. The two sliding holes and locking pieces can ensure that the spring sheet can maintain a certain balance and be located at the same horizontal height when installed on the upper module. That is, when the spring sheet acts on each folding edge, the bending amount and inclination angle of each folding edge of the spring sheet can be uniformly guaranteed, thereby preventing the folding edge from being uneven and irregular when being flattened, thereby effectively ensuring product quality.
[0019] (5) By setting a limit baffle between the locking member and the spring sheet, the limit baffle can limit the travel of the spring sheet along the locking member, effectively preventing the spring sheet from shaking and tilting along the axial direction of the locking member after installation or when deformed, and further preventing the folded edge from becoming uneven when being flattened, thereby effectively ensuring product quality.
[0020] (6) The sheet metal part is positioned on the lower module by means of positioning pins, so that the corresponding position of the folded edge and the spring sheet on the upper module can be more accurate, thus ensuring the accuracy of the folded edge after processing.

[0038] This embodiment provides a multi-faceted folding edge A1 stamping and forming device, which is mainly used to solve the problem that the existing mold operation can only process the folding edge A1 one by one, the mold investment cost and the processing cost of the sheet metal part A are high, it is time-consuming and labor-intensive, and the production efficiency is low; the stamping device mainly includes; wherein, including
[0039] Next module 1, see Figure 1 and Figure 2 , which is placed vertically upward perpendicular to the horizontal plane, and a positioning pin 11 is provided on the side wall of the lower module 1, and the sheet metal part A is positioned and placed on the lower module 1 through the positioning pin 11 to be supported and installed; see Figure 3 , the plurality of folded edges A1 of the sheet metal part A are arranged at intervals and are all horizontally vertically or tilted upwards;
[0040] The clamping assembly 2 is located at the side end of the lower module 1; the clamping assembly 2 includes a clamping plate 21 and a driving mechanism 22, see Figure 1 and Figure 2 The driving mechanism 22 can drive the clamping plate 21 to move toward the sheet metal part A to constrain and fix the sheet metal part A on the lower module 1; the driving mechanism 22 includes a swingable swing rod, and the clamping plate 21 is driven to move toward the lower module 1 by the swing of the swing rod to act on the sheet metal part A to constrain and fix it;
[0041] On module 3, see Figure 3 , corresponding to the lower module 1 located above it; see Figure 5 It's hot Figure 6 , at least one "C"-shaped spring piece 31 is provided on the outer periphery of the upper module 3, and the spring piece 31 corresponds to the folded edge A1 of the sheet metal part A;
[0042] The upper module 3 moves downward relative to the lower module 1, and the spring pieces 31 abut against each folded edge A1 and drive it to tilt toward the inner side of the lower module 1 at a certain angle, so that when the upper module 3 approaches the lower module 1 and closes, the upper module 3 can press the inwardly bent folded edge A1 against the lower module 1 to flatten it.
[0043] In this embodiment, see Figure 3 When the sheet metal part A is placed on the lower module 1, the free ends of the folded edges A1 of the sheet metal part A are horizontally vertical or tilted upward. In this way, when the upper module 3 is pressed down, the spring pieces 31 on the upper module 3 can drive the folded edges A1 to be pre-concentrated and tilted inwardly at a certain angle toward the inner side of the lower module 1, so that the upper module 3 can continue to press down and press the folded edges A1 uniformly on the upper end of the lower module 1; if the folded edge A1 extends to the left or right, the spring piece 31 cannot drive the folded edge A1 to deform, and the purpose cannot be achieved.
[0044] In this embodiment, see Figures 7 to 9 When the upper module 3 approaches the lower module 1 and closes, the spring piece 31 abuts against the sheet metal part A and is compressed and deformed, and as the upper module 3 continues to descend, the spring piece 31 located on the outer side of the lower module 1 gradually slides downward to move away from the working surface of the lower module 1, thereby preventing the spring piece 31 from interfering with the flattening action of the upper module 3 and the lower module 1, thereby achieving an avoidance effect.
[0045] In this embodiment, a locking member 4 and a limit baffle 5 are also included. Figure 5 and Figure 6 The locking member 4 passes through the limit baffle 5 and the spring piece 31 one by one and is locked and connected with the upper module 3, and the spring piece 31 is installed on the upper module 3; the setting of the limit baffle 5 can also limit the travel of the spring piece 31 along the locking member 4, preventing the spring piece 31 from shaking and tilting significantly.
[0046] In this embodiment, the locking member 4 is a bolt, and the upper module 3 has a screw hole that is threadedly engaged with the locking member 4 .
[0047] In this embodiment, see Figure 5 and Figure 6 The spring piece 31 has a sliding hole 311, the locking member 4 passes through the limit baffle 5, and the sliding hole 311 is screwed to the upper module 3. The sliding hole 311 is waist-shaped, so the spring piece 31 can slide along the radial direction of the locking member 4 through the sliding hole 311; when the upper module 3 moves downward relative to the lower module 1, see Figure 8 , the upper module 3 drives the spring sheet 31 to abut against the folded edge A1 so that the spring sheet 31 cannot move; at this time, the upper module 3 continues to move downward, see Figure 8 The locking member 4 screwed to the upper module 3 slides along the sliding hole 311 for a certain distance, so that the distance between the upper module 3 and the spring 31 becomes smaller; then the upper module 3 continues to move downward, see Figure 8 , the upper module 3 drives the spring 31 to abut against the folded edge A1 to make it tilt; see Fig. 9 As the upper module 3 moves downward, the spring piece 31 abuts against the sheet metal part A and is compressed and deformed (not abutted against the folded edge A1 and deformed), and the spring piece 31 gradually slides downward on the outside of the lower module 1, driving the spring piece 31 away from the sheet metal part A.
[0048] In this embodiment, the elastic force of the spring sheet 31 is indispensable, that is, it is necessary to ensure that the spring sheet 31 can drive the folding edge A1 to bend and tilt when it moves downward, and it is also necessary to ensure that it will not interfere with the subsequent flattening work after the action is completed. Therefore, a spring sheet 31 with elastic force is used to achieve the purpose by elastic shape change. When the upper module 3 moves downward, the spring sheet 31 presses against the sheet metal part A for compression and deformation, and slides downward on the outer side of the lower module 1; when the upper module 3 moves upward, at this time, since the spring sheet 31 presses against the sheet metal part A for compression and deformation, if the locking member 4 directly drives the spring sheet 31 to move upward, the spring sheet 31 will produce friction noise corresponding to the sheet metal part A. Therefore, the design of the sliding hole 311 allows the locking member 4 to slide a certain distance in the sliding hole 311 for buffering first, so that the spring sheet 31 releases a certain pressing force relative to the sheet metal part A on the lower module 1, and then drives the spring sheet 31 away from the upper working surface of the lower module 1, which can effectively prevent the lower module 1 and the sheet metal part A from having continuous friction noise.
[0049] In this embodiment, see Figure 5 and Figure 6 There are at least two sliding holes 311 and locking members 4 on the spring sheet 31, and the sliding holes 311 and the locking members 4 are arranged at the same level. Each locking member 4 is respectively guided through each sliding hole 311, and the spring sheet 31 is installed on the upper module 3. The spring sheet 31 is prevented from tilting or automatically rotating by positioning and installing it in pairs.
[0050] In this embodiment, an upper die base and a lower die base 6 are also included. A die handle 32 is provided at the upper end of the upper die block 3 . The die handle 32 is connected and installed with the upper die base. The lower die block 1 and the clamping assembly 2 are fixed on the lower die base 6 .
[0051] The working principle and use process of this utility model:
[0052] When processing sheet metal part A, refer to Figure 2 , place two sheet metal parts A on the lower module 1, one on the left and one on the right;
[0053] Afterwards, see Figure 3 , respectively controlling the movement of the swing rods in the two driving mechanisms 22, driving the two clamping plates 21 to move toward the sheet metal part A to clamp and fix it, at which time the folded edge A1 of the sheet metal part A will be perpendicular to the horizontal and vertically upward or inclined;
[0054] Next, see Figures 7 to 9 , control the upper module 3 to move downward relative to the lower module 1; see Figure 8 , the upper module 3 drives the spring sheet 31 to abut against each folding edge A1; as the upper module 3 continues to move downward, the locking member 4 screwed to the upper module 3 slides a certain distance along the sliding hole 311 due to the abutment of the spring sheet 31, so that the distance between the upper module 3 and the spring sheet 31 becomes smaller;
[0055] Finally, the upper module 3 continues to descend relative to the lower module 1, see Fig. 9, the spring sheet 31 makes each folded edge A1 tilted toward the inner side of the lower module 1 at a certain angle; and as the spring sheet 31 moves downward, it abuts against the sheet metal part A and is compressed and deformed, gradually sliding downward on the outer side of the lower module 1, driving the spring sheet 31 away from the sheet metal part A; the upper module 3 then closes relative to the lower module 1, flattens each bent and tilted folded edge A1 on the working surface of the lower module 1, and completes Figure 4 Sheet metal part A shown.
[0056] During the return stroke, the upper module 3 is controlled to move upward relative to the lower module 1, and the locking member 4 slides a certain distance in the sliding hole 311 for buffering first, and then drives the spring 31 away from the upper working surface of the lower module 1. At this time, the rocker movement in the two driving mechanisms 22 can be controlled to drive the two clamping plates 21 to release the constraint of the sheet metal part A and take the sheet metal part A out of the lower module 1. The utility model has a simple structure and is easy to use. The device reduces the number of molds and manufacturing time, greatly reduces the mold development cost, and shortens the parts production cycle. It can easily and quickly produce a sheet metal part A with multiple side bends, thereby improving production efficiency. During processing, the spring piece 31, under the action of the upper module 3, drives the folded edge A1 of the sheet metal part A to be tilted toward the inner side of the lower module 1 in advance at a certain angle. In this way, when the upper module 3 approaches the lower module 1 for pressing, the folded edge A1 can continue to bend toward the inner side of the lower module 1 until it is flattened. During the whole process, multiple folded edges A1 can be bent at the same time at one time, with extremely high production efficiency, and can ensure that the flatness of each folded edge A1 is more uniform, thereby improving product quality.
[0057] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
