[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 The lower mold base 100 has first fixed seats 101 installed at both bottom ends, and the upper mold base 102 has second fixed seats 103 installed at both top ends. The top end of the edge-binding block 108 has a bevel 10801 that matches the bevel block 107. A pair of retaining blocks 113 are installed on the other two sides of the upper mold base 102. The bottom end of the retaining block 113 is equipped with a limit rod 114. A pair of sliding sleeves 115 are installed on the other two sides of the lower mold base 100. The outer side of the limit rod 114 and the inner side of the sliding sleeve 115 are slidably connected. The lower mold base 100 has first fixed seats 101 installed at both bottom ends. 1. The lower die base 100 is conveniently fixed on the worktable of the stamping equipment. The upper die base 102 is reliably connected to the power end of the stamping equipment by installing second fixed seats 103 on both sides of the top. The edge-binding block 108 has a bevel 10801 at the top that matches the bevel block 107. When the bevel block 107 is pressed down with the upper die base 102, the bevel 10801 guides the edge-binding block 108 to slide and bind the edge of the sheet metal part. The setting of the holding block 113, the limiting rod 114 and the sliding sleeve 115 improves the pressing stability of the upper die base 102.
[0025] Specifically, the working principle of this sheet metal edge-wrapping mold is as follows: During use, a support plate 110 is provided inside the first groove 10001 to place and support the sheet metal part, preventing localized deformation due to pressure. An edge-wrapping block 108 is provided inside the second groove 10002 to perform the edge-wrapping function. A spring 112 is installed at the bottom of the slide rod 111 to automatically reset the support plate 110 after it descends. A pressure block 105 is installed at the bottom of the first column 104. This mechanism firmly presses the sheet metal parts onto the support plate 110, preventing displacement during subsequent edge-wrapping operations. Simultaneously, it works in conjunction with the edge-wrapping block 108 to lift the outer edge of the sheet metal parts, facilitating edge-wrapping by the block 108. A wedge block 107 is installed at the bottom of the second column 106; as the upper mold base 102 descends, the wedge block 107 pushes the edge-wrapping block 108 to move and wrap the edge. The edge-wrapping is achieved through the arrangement of the fixed block 10901, tension spring 10902, and movable block 10903. The automatic reset of block 108 after movement is achieved by sliding the top and bottom ends of movable block 10903 to the top and bottom ends of slide 10004, respectively, thus improving the movement stability of movable block 10903. First fixed seats 101 are installed on both bottom ends of the lower die base 100 to facilitate its fixation on the worktable of the stamping equipment. Second fixed seats 103 are installed on both top ends of the upper die base 102 to connect the upper die base 102 to the power end of the stamping equipment. The reliable connection is achieved by providing a beveled edge 10801 at the top of the edge-binding block 108 that matches the beveled block 107. When the beveled block 107 is pressed down with the upper mold base 102, the beveled edge 108 guides the edge-binding block 108 to slide, thus binding the edge of the sheet metal part. The setting of the holding block 113, the limiting rod 114 and the sliding sleeve 115 improves the pressing stability of the upper mold base 102. This utility model can effectively realize the automatic edge-binding function, improve the edge-binding efficiency, and has high practical value.
[0026] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
