Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a sheet metal stamping forming and unloading structure. Background Technology

[0002] In the stamping process of sheet metal, molds are used for stamping. Since it is dangerous to manually remove the stamped sheet metal parts in the actual stamping equipment, a material discharge structure is installed on the stamping equipment to avoid accidents.

[0003] A search revealed a patent, CN220901718U, which discloses a sheet metal stamping and unloading structure. This invention solves the problem that traditional unloading methods require manual adjustment of the screw rod after the mold rises, making automatic unloading cumbersome. By incorporating a clamping mechanism and a reciprocating mechanism, the reciprocating mechanism drives the clamping mechanism downwards and backwards when the air spring and impact mold move downwards, preventing the clamping plate from affecting the sheet metal. When the air spring and impact mold move upwards, the reciprocating mechanism drives the clamping mechanism upwards and forwards, clamping the sheet metal and causing it to move upwards, thus completing the unloading process. Compared to existing technologies, this invention automatically unloads the sheet metal after impact, simplifying the unloading process.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents use clamping plates to hold one side of the stamped sheet metal part to achieve the effect of unloading the sheet metal part. However, in actual operation, many sheet metal parts are quite thin. When only one side of the sheet metal part is clamped and moved, it may cause deformation of the thin sheet metal part, reducing the applicability of the sheet metal part stamping and unloading structure. Therefore, there is an urgent need in the art to improve the sheet metal part stamping and unloading structure to solve the defects of the prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a sheet metal stamping and forming ejection structure, which reduces the likelihood of deformation during sheet metal ejection and improves the applicability of the sheet metal stamping and forming ejection structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal stamping forming and unloading structure, comprising a stamping device body, a telescopic device, an upper die, and a lower die adapted to the upper die. The telescopic device drives the upper die to move up and down. A fixing plate is fixedly installed on the front side of the stamping device body. A rotating column is rotatably connected to the upper part of the fixing plate. A drive motor for driving the rotating column to rotate is fixedly installed on the lower part of the fixing plate. Positioning seats are provided on opposite sides of the rotating column. A connecting plate is provided above the positioning seats. A feeding frame adapted to the lower die is fixedly installed at the end of the connecting plate away from the positioning seats. A positioning platform is provided on the upper part of the feeding frame. A springback unit is provided between the positioning seats and the connecting plate. The springback unit is used to limit and spring back the connecting plate.

[0008] Preferably, the rebound unit includes a plurality of connecting columns disposed on the upper part of the positioning seat and penetrating the connecting plate, a limit plate is fixedly installed on the upper end of the connecting column, and an elastic element is sleeved on the side of the connecting column.

[0009] Preferably, the lower end of the connecting column is threadedly connected to the upper part of the positioning seat.

[0010] Preferably, an adjusting block is fixedly installed on the side of the positioning seat near the rotating column, and adjusting grooves adapted to the adjusting blocks are opened on opposite sides of the rotating column. Two adjusting threaded rods threadedly connected to the corresponding adjusting blocks pass through the upper end of the rotating column, and limit nuts are threadedly connected to the sides of the adjusting threaded rods.

[0011] Preferably, a scale plate is fixedly installed on the side of the rotating column, and the scale plate is provided with a scale that matches the adjustment groove.

[0012] Preferably, the lower mold side is provided with a clearance step, and the material feeding frame is adapted to the clearance step.

[0013] Preferably, the main body of the stamping device is provided with a main controller for control on its side, and the front side of the main body of the stamping device is provided with a starter adapted to the position of the feeding frame, and the starter is electrically connected to the main controller.

[0014] To address the shortcomings of existing technologies, this utility model provides a sheet metal stamping and forming ejection structure, overcoming the deficiencies of existing technologies. The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the sheet metal part is placed in the positioning table position in the feeding frame. With the springback unit between the connecting plate and the positioning seat, after the stamping is completed, the upper mold moves upward and the connecting plate drives the feeding frame to move upward. Since the four sides of the stamped sheet metal part are supported and moved upward, the sheet metal part is not prone to deformation, thus improving the applicability of the sheet metal part stamping and forming output structure.

[0016] 2. In this utility model, by setting a drive motor to drive the rotating column to rotate intermittently, the operator can take out the sheet metal parts that are far away from the main body of the stamping device and have been stamped during the sheet metal stamping process, and place the sheet metal parts to be stamped. This realizes the dual-station loading and unloading of sheet metal parts, and at the same time, the operator does not need to put his / her hands into the main body of the stamping device to pick up and put in the sheet metal parts. This improves the efficiency of sheet metal stamping and forming, and also improves the safety factor in the stamping process.

[0017] 3. In this utility model, the height of the positioning seat can be adjusted by rotating the adjusting threaded rod, thereby adjusting the position of the feeding frame. Furthermore, the connecting plate and the feeding frame can be replaced by the connecting column threaded onto the positioning seat, further improving the applicability of the device.

[0026] 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.

[0027] Example 1

[0028] Please see Figures 1-5 A sheet metal stamping forming and unloading structure includes a stamping device body 1, a telescopic device 2, an upper die 3, and a lower die 4 adapted to the upper die 3. The telescopic device 2 drives the upper die 3 to move up and down. A fixing plate 5 is fixedly installed on the front side of the stamping device body 1. A rotating column 6 is rotatably connected to the upper part of the fixing plate 5. A drive motor 7 for driving the rotating column 6 to rotate is fixedly installed on the lower part of the fixing plate 5. Positioning seats 8 are provided on opposite sides of the rotating column 6. A connecting plate 9 is provided above the positioning seats 8. A feeding frame 10 adapted to the lower die 4 is fixedly installed at the end of the connecting plate 9 away from the positioning seats 8. A positioning platform 11 is provided on the upper part of the feeding frame 10. The positioning seats 8 and the connecting plate 9 are connected to the lower die 4. A spring-back unit is provided between the connecting plates 9. The spring-back unit is used to limit and spring back the connecting plates 9. The spring-back unit includes several connecting posts 13 located on the upper part of the positioning seat 8 and passing through the connecting plates 9. A limiting plate 14 is fixedly installed on the upper end of the connecting post 13. An elastic element 12 is sleeved on the side of the connecting post 13. The lower end of the connecting post 13 is threadedly connected to the upper part of the positioning seat 8. A clearance step 19 is provided on the side of the lower mold 4. The feeding frame 10 is adapted to the clearance step 19. A main controller 21 for control is provided on the side of the stamping device body 1. A starter 22 adapted to the position of the feeding frame 10 is provided on the front side of the stamping device body 1. The starter 22 is electrically connected to the main controller 21.

[0029] The specific implementation method in this embodiment is as follows: When it is necessary to stamp a sheet metal part, the sheet metal part to be stamped is placed in the positioning table 11 in the feeding frame 10 on the side away from the main body 1 of the stamping device. The positioning table 11 is adapted to the size of the sheet metal part to be stamped and limits the sheet metal part to be stamped. By pressing the start button on the starter 22, the starter 22 transmits the signal to the main controller 21. The main controller 21 controls the start of the drive motor 7. The output end of the drive motor 7 drives the rotating column 6 to rotate. The rotating column 6 drives the feeding frame 10 to rotate, rotating the sheet metal part to be stamped to be directly above the lower mold 4. The telescopic mechanism is then activated by the main controller 21. Device 2, the telescopic end of the telescopic device 2 drives the upper mold 3 to move downward. When the upper mold 3 contacts the sheet metal part to be stamped, the upper mold 3 pushes the feeding frame 10 downward. The feeding frame 10 moves to the side of the lower mold 4 and is located at the clearance step 19. The cooperation of the upper mold 3 and the lower mold 4 completes the stamping and forming of the sheet metal part. After forming, the four edges of the sheet metal part are still located on the positioning table 11. The downward movement of the feeding frame 10 drives the connecting plate 9 to move downward. The connecting plate 9 slides on the side of several connecting posts 13. The elastic element 12 is a spring. When the connecting plate 9 moves downward, the elastic element 12 is compressed. After the stamping and forming of the sheet metal part is completed, the upper mold 3 moves upward. At this time, the tension of the elastic element 12 pushes the connecting plate 9 upward, and the connecting plate 9 drives the feeding frame 10 upward. Since the four edges of the stamped sheet metal part are supported and moved upward, the sheet metal part is less likely to deform, thus improving the applicability of the sheet metal part stamping and forming output structure. The upward movement of the feeding frame 10 causes the stamped sheet metal part to detach from the lower mold 4. The drive motor 7 is started again, and the drive motor 7 drives the rotating column 6 to rotate. During the sheet metal part stamping process, the operator can take out the sheet metal part that is far away from the main body 1 of the stamping device and has been stamped, and place the sheet metal part to be stamped. This realizes the dual-station loading and unloading of stamped sheet metal parts, and at the same time, no operator is required. Reaching into the main body 1 of the stamping device to pick up and place sheet metal parts not only improves the efficiency of sheet metal stamping and forming, but also increases the safety factor during the stamping process. The lower end of the connecting column 13 is threaded to the upper part of the positioning seat 8, allowing the connecting column 13 and the elastic element 12 to be replaced. Different elastic elements 12 with different elastic coefficients or connecting columns 13 of different lengths can be replaced according to the actual stamping shape of the sheet metal parts. At the same time, the connecting column 13 plays a role in preventing deformation of the elastic element 12. The shape of the feeding frame 10 can be customized according to the shape of the sheet metal parts, further improving the applicability of the device. The limiting plate 14 is used to limit the connecting plate 9.

[0030] Example 2

[0031] Please see Figure 3 and Figure 4This embodiment includes the above embodiment, and further includes: an adjustment block 15 is fixedly installed on the side of the positioning seat 8 near the rotating column 6; the rotating column 6 has adjustment grooves 16 adapted to the adjustment blocks 15 on opposite sides; two adjustment threaded rods 17 are threaded through the upper end of the rotating column 6 and are threadedly connected to the corresponding adjustment blocks 15; limit nuts 18 are threadedly connected to the side of the adjustment threaded rods 17; a scale plate 20 is fixedly installed on the side of the rotating column 6, and the scale plate 20 has scales adapted to the adjustment grooves 16.

[0032] In this specific embodiment, when sheet metal parts of different thicknesses need to be stamped with lower dies of different thicknesses, the overall height of the feeding frame 10 needs to be adjusted. At this time, the adjusting threaded rod 17 is rotated. When the adjusting threaded rod 17 rotates, it drives the adjusting block 15 to slide in the adjusting groove 16. The adjusting block 15 drives the positioning seat 8 to move. Observe the scale plate 20 with scale, thereby achieving the effect of adjusting the height position of the feeding frame 10. Then, the locking limit nut 18 is tightened to limit and fix the position of the positioning seat 8, further improving the applicability of the device.
