Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-7As shown, the present invention discloses an automatic material discharge stamping die, comprising a fixed die 1, a movable die 2, a wedge assembly 3, a waste material discharge assembly 4, a die base 5, and a forming plate 6. Die bases 5 are fixedly connected to both the fixed die 1 and the movable die 2. The fixed die 1 and the movable die 2 form a spatial shape identical to the forming plate 6 through surface contact. The wedge assembly 3 is disposed between the fixed die 1 and the movable die 2. The waste material discharge assembly 4 is used to discharge waste material during the processing of the forming plate 6. The waste material discharge assembly 4 is detachably connected to the fixed die 1. During stamping, the movable die 2 slides on the fixed die 1. During its up-and-down movement, the wedge assembly 3 deforms. During the downward movement, the wedge assembly 3 pushes the movable die 2, causing the movable die 2 to exert more force on the forming plate 6, resulting in a better bending effect and more stable stamping process for the forming plate 6. This leads to a better forming effect for the forming plate 6. Furthermore, waste material falling during the punching operation can be automatically discharged by the waste material discharge assembly 4.

[0030] Furthermore, the waste discharge assembly 4 includes a first discharge plate 41 and a second discharge plate 42. Multiple second discharge plates 42 are located at the upper end of the first discharge plate 41 and on the same side of the fixed mold 1 as the first discharge plate 41. The rear ends of the multiple second discharge plates 42 are all located in front of the rear end of the first discharge plate 41. The first discharge plate 41 and the multiple second discharge plates 42, which can be set at different vertical positions, can respectively receive the waste generated by punching. Furthermore, since the first discharge plate 41 and the multiple second discharge plates 42 are inclined, the waste can be automatically discharged from the fixed mold 1, effectively preventing the waste from clogging the fixed mold 1 and ensuring the smooth operation of stamping.

[0031] Furthermore, the waste discharge assembly 4 also includes a waste collection trough 43. Multiple waste collection troughs 43 are detachably connected to the fixed mold 1. The multiple waste collection troughs 43 are located on the other side of the fixed mold 1 away from the first discharge plate 41 and the multiple second discharge plates 42. Each of the multiple waste collection troughs 43 is fixedly connected to a push-pull handle 44. The waste collection trough 43 is used to collect waste material located on the side away from the first discharge plate 41 and the second discharge plate 42 during the punching process for automatic discharge and collection. After collection, the waste collection trough 43 can be pulled out by pulling the corresponding push-pull handle 44 to dump the waste material in a concentrated manner, which is beneficial for the centralized collection of waste material.

[0032] Furthermore, the fixed mold 1 includes a fixed mold base 11, guide pillars 12, buffers 13, a display screen 14, and conical buffers 15. Multiple guide pillars 12 are fixedly connected to the fixed mold base 11. Two buffers 13 are symmetrically fixed to the fixed mold base 11. The display screen 14 is fixed to the upper center of the fixed mold base 11. Multiple conical buffers 15 are all fixedly connected to the fixed mold base 11. The first discharge plate 41 and multiple second discharge plates 42 are all fixedly connected to the fixed mold base 11. The multiple guide pillars 12 can restrict the vertical movement of the movable mold 2. Positioning and guiding prevent axial deflection of the moving mold 2. The setting of buffer 13 and conical buffer 15, with multiple conical buffers 15 and two buffers 13 distributed, can always disperse the excessive impact force generated by the moving mold 2 during the stamping process, playing a buffering role, protecting the stamping die as a whole, increasing the service life of the stamping die, and preventing the die from being damaged due to excessive stamping pressure. The display screen 14 is located in the middle of the upper end of the fixed mold base 11, which is convenient for setting and starting or stopping the stamping operation during use.

[0033] Furthermore, the fixed mold 1 also includes a mold placement plate 17. Multiple mold placement plates 17 are provided, and the multiple mold placement plates 17 are respectively fixed to the four corners of the upper end of the fixed mold base 11. The upper end of the multiple mold placement plates 17 is used to place the movable mold 2 to work with the fixed plate. When the support is completed, the fixed movable mold 2 and the fixed mold 1 are fixed, and after fixing, they can be hoisted and moved.

[0034] Furthermore, the fixed mold base 11 is provided with multiple waste discharge grooves 16, and multiple waste collection grooves 43 are detachably connected to the multiple waste discharge grooves 16. The multiple waste collection grooves 43 are respectively used to receive the waste in the multiple waste discharge grooves 16 to prevent the waste from jumping out and causing the punching failure during stamping.

[0035] Furthermore, the movable mold 2 includes a movable mold base 21, guide post grooves 22, ejector pins 23, ejector rods 24, lifting lugs 29, and a stamping die core 210. The movable mold base 21 is provided with multiple guide post grooves 22, which are slidably connected to multiple guide posts 12. Multiple ejector pins 23 are disposed between the movable mold base 21 and the stamping die core 210. The stamping die core 210 is slidably connected to the movable mold base 21. Both the stamping die core 210 and the movable mold base 21 are slidably connected to a fixed mold base 11. Multiple ejector rods 24 are fixedly connected to... On the movable mold base 21, multiple ejector pins 24 are slidably connected to the stamping die core 210. The guide post groove 22 cooperates with the corresponding guide post 12 to play a guiding role. Multiple lifting ears 29 are fixed to the movable mold base 21 for lifting when the stamping die is moved and replaced. The multiple lifting ears 29 are symmetrically arranged so that the center of gravity of the movable mold base 21 is located at the center of the movable mold base 21 during the lifting process. After the stamping is completed, the ejector pin 23 pushes out the stamping die core 210, thereby realizing the separation of the stamping die core 210 from the forming plate 6.

[0036] Furthermore, the movable mold 2 also includes a punching punch I 25, a punch connecting plate 26, and a punching punch II 36. Multiple punching punches I 25 and punching punch II 36 are provided. Multiple punching punches II 36 are fixed to the stamping die core 210. Multiple punching punches I 25 are fixed to the stamping die core 210 through the punch connecting plate 26. During the stamping process, the stamping die core 210 moves with the movable mold base 21 and acts on the placed sheet metal, causing the sheet metal to bend and form an L-shaped forming plate 6. At the same time, as the stamped part is stamped, the punching punches I 25 and punching punches II 36 act on the forming plate 6 to form holes. The waste material on the outer side falls out by multiple second discharge plates 42, and the waste material on the inner side and near the center falls out by the first discharge plate 41. The slag material generated during the stamping process falls into multiple waste collection tanks 43 for collection and discharge.

[0037] Furthermore, the wedge group 3 includes side wedges 31 and inner push wedges 32. Multiple side wedges 31 are arranged on the left and right sides of the upper end of the fixed mold base 11, and multiple inner push wedges 32 are fixedly connected to the fixed mold base 11. Multiple inner push wedges 32 are located between multiple side wedges 31. During the stamping process, the moving mold 2 gradually moves down, and the side wedges 31 and inner push wedges 32 generate a pushing force on the stamping mold core 210 to clamp the raw material plate.

[0038] Further, the side wedge 31 includes a bottom fixing block 311, a slanted push wedge 312, and a movable wedge plate 313. The movable wedge plate 313 is slidably connected to the bottom fixing block 311, and the slanted push wedge 312 is slidably connected to the movable wedge plate 313. Multiple bottom fixing blocks 311 are fixedly connected to the fixed mold base 11, and multiple slanted push wedges 312 are fixedly connected to the movable mold base 21. The inner push wedge 32 includes an inner bottom fixing block 321, an inner slanted push wedge 322, and an inner movable wedge plate 323. The inner movable wedge plate 323 is slidably connected to the inner bottom fixing block 321, and the inner slanted push wedge 322 is slidably connected to the inner movable wedge plate 323. Multiple inner bottom fixing blocks 321 are fixedly connected to the fixed mold base 11, and multiple... The inner inclined push wedges 322 are all fixedly connected to the movable mold base 21. Multiple inner movable wedge plates 323 and multiple movable wedge plates 313 are provided with push plates for applying pressure to the stamping die core 210. Multiple inner movable wedge plates 323 and multiple movable wedge plates 313 are respectively provided with springs between them and the inner bottom fixing block 321 and the bottom fixing block 311. As the inclined push wedges 312 and inner inclined push wedges 322 fall with the movable mold base 21, the corresponding movable wedge plates 313 and inner movable wedge plates 323 move under the push of the inclined surface, gradually approaching the stamping die core 210, applying pressure to the stamping die core 210, providing clamping force, and playing the role of raw material. At the same time, it makes the raw material more stable during the pressure process, resulting in better bending effect.
