Description

Technical Field

[0001] This utility model belongs to the field of sheet metal stamping forming mold technology, specifically relating to a sheet metal parts flanging forming mold. Background Technology

[0002] Sheet metal parts are core basic components in industries such as automobiles, home appliances, and instruments. Their flanging process not only enhances the edge strength of the parts and enables assembly positioning, but also optimizes the appearance of the parts and meets the structural requirements of different scenarios. In the mass production of sheet metal parts, stamping dies are the core equipment for achieving flanging. The workflow is usually as follows: the upper module moves down to apply pressure to the sheet metal sheet, causing the sheet to bend along the groove on the lower module. The upper module moves up to remove the formed part, and then a new blank is placed in to complete one production cycle.

[0003] However, during the flanging process, the sheet metal parts are subjected to pressure from the upper module and fit against the mold cavity. After forming, the parts are easily adhered tightly to the surface of the upper module's punch due to friction, material springback, or slight deformation. At this point, it is necessary for the operator to manually peel the parts off the upper punch, which is time-consuming and results in low production efficiency. In addition, frequent material handling can easily cause operator fatigue, which can lead to physical discomfort and operational errors, potentially causing serious consequences.

[0018] 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.

[0019] Please see Figures 1 to 6 As shown, this utility model embodiment provides a sheet metal part flanging forming mold, including a lower module 1, a receiving structure 2 on the lower module 1, the receiving structure 2 including a connecting post 201 and a connecting sleeve 202, the connecting post 201 being fixedly connected to the lower module 1, the connecting sleeve 202 being rotatably connected to the outer side of the connecting post 201, the connecting sleeve 202 being provided with a first guide groove 203, a movable plate 5 being provided at the top of the lower module 1, an upper module 6 being mounted on the movable plate 5, a first guide shaft 204 being fixedly connected to the movable plate 5, the first guide shaft 204 extending into the interior of the first guide groove 203, and the connecting sleeve 202... A connecting rod 205 is fixedly connected to the upper part of the moving plate 5. A receiving plate 206 is rotatably connected to the end of the connecting rod 205. A gear 207 is fixedly connected to the receiving plate 206. A sliding rod 209 is slidably connected to the connecting rod 205. A rack 208 is fixedly connected to the sliding rod 209. The gear 207 and the rack 208 mesh with each other. A second guide shaft 210 is fixedly connected to the sliding rod 209. A connecting plate 212 is fixedly connected to the connecting column 201. A second guide groove 211 is provided on the connecting plate 212. The bottom end of the second guide shaft 210 extends into the interior of the second guide groove 211. A top plate 4 is provided on the top side of the moving plate 5.

[0020] In use, this utility model fixes the top of the connecting column 9 to the output end of the stamping machine, thus enabling the stamping machine to drive the connecting column 9 to move. The movement of the connecting column 9 will drive the moving plate 5 to move. After the sheet metal is stamped and rolled, the moving plate 5 will drive the upper module 6 to move upward. During this movement, the moving plate 5 will drive the first guide shaft 204 to move inside the first section of the first guide groove 203. At this time, the connecting sleeve 202 will not rotate. As the upper module 6 continues to move, its bottom position will be higher than the top side of the receiving tray 206. At this time, the first guide shaft 204 will... The second section of the first guide groove 203 moves internally, while the connecting sleeve 202 rotates. The rotation of the connecting sleeve 202 drives the connecting rod 205 to move, which in turn drives the receiving tray 206 towards the upper module 6. When the receiving tray 206 is directly below the upper module 6, the first guide shaft 204 moves to the inside of the third section of the first guide groove 203. Then, as the moving plate 5 continues to move, the rotating sleeve 202 does not rotate. During the continued movement of the moving plate 5, the two push rods 701 abut against the top plate 4, and then the two push rods 701 push the formed product from the upper module 6. The upper ejector falls onto the receiving tray 206. During the mold closing process, the moving plate 5 will move in the opposite direction. When the moving plate 5 moves in the opposite direction, the rotating sleeve 202 will rotate in the opposite direction. When the rotating sleeve 202 rotates, the second guide shaft 210 will move inside the second guide groove 211. When the second guide shaft 210 moves inside the first section of the second guide groove 211, the slide rod 209 will not move. When the second guide shaft 210 moves inside the second section of the second guide groove 211, the slide rod 209 will slide on the connecting rod 205. The movement of the slide rod 209 will drive the rack 208 to move, and the rack 208 will drive the gear 207 to rotate. The gear 207 drives the receiving tray 206 to rotate. As the receiving tray 206 rotates, the products on it will fall into the collection device under the action of gravity for collection. This realizes automatic unloading of the products after flanging, avoiding the need for manual unloading by operators, improving production efficiency and operational safety. When placing sheet metal parts that have not yet been flanged, the multiple stops 802 can be used to abut against the edge of the sheet metal parts to position the sheet metal parts, thereby avoiding deviation in the position of the sheet metal parts and effectively improving the stability of flanging.

[0021] Please see Figures 1 to 6As shown, the first guide groove 203 is divided into three sections. The first and third sections are vertically arranged, while the second section has a spiral structure. Therefore, when the first guide shaft 202 moves inside the second section of the first guide groove 203, the connecting sleeve 202 will rotate. The second guide groove 211 is divided into two sections. The center of the arc of the first section is at the same point as the center of the connecting plate 212, while the center of the arc of the second section is offset from the center of the connecting plate 212. Therefore, when the second guide shaft 210 moves inside the second section of the second guide groove 211, the slide rod 209 will slide on the connecting rod 205. The receiving plate 206 is horizontally arranged, thus allowing materials to be placed stably on the receiving plate 206. The connecting rod 205 is perpendicular to the connecting sleeve 202.

[0022] Please see Figures 1 to 6 As shown, two guide pillars 3 are fixedly connected to the lower module 1. The two guide pillars 3 are fixedly connected to the top plate 4 near the top, thus supporting and fixing the top plate 4 through the two guide pillars 3. The same movable plate 5 is slidably connected to the two guide pillars 3, thus guiding the movement of the movable plate 5 through the two guide pillars 3. A connecting pillar 9 is fixedly connected to the top side of the movable plate 5, and the connecting pillar 9 passes through the top plate 4, thus connecting to the output end of the stamping machine through the connecting pillar 9.

[0023] Please see Figures 1 to 6 As shown, the upper module 6 has an ejection structure 7 inside, which includes a push rod 701 and a spring 702. Two push rods 701 are slidably connected inside the upper module 6. The spring 702 is sleeved on the outside of the push rod 701, and a connecting ring 703 is fixedly connected to the outside of the push rod 701. One end of the spring 702 abuts against the connecting ring 703, and the other end of the spring 702 abuts against the upper module 6. Therefore, when the push rod 701 and the top plate 4 are separated, they can be reset under the action of the spring 702. The bottom end of the push rod 701 is flush with the bottom end of the upper module 6, and the width of the bottom section of the push rod 701 is greater than the width of the top section, thus preventing the push rod 701 from sliding out of the upper module 6.

[0024] Please see Figures 1 to 6 As shown, the lower module 1 is provided with a positioning structure 8, which includes a slider 801 and a stop bar 802. Multiple sliders 801 are slidably connected to the lower module 1, and a stop bar 802 is fixedly connected to the slider 801. A knob 803 is threadedly connected to the slider 801, and one end of the knob 803 abuts against the lower module 1, thus enabling the positioning of sheet metal parts that need to be flanged.
