Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and specifically discloses a floating stamping blanking structure. Background Technology

[0002] Continuous stamping is a metalworking method that may include stamping, drawing, bending and other methods of processing metal raw materials, combined with an automatic feeding system. The feeding system pushes the metal strip through all the stations of a continuous die. A continuous stamping die is a cold stamping die that uses a single raw material to complete multiple stamping operations at different stations on a single die. The strip moves a fixed distance, once per stroke, until the finished product is produced.

[0003] like Figure 1 The product shown is formed by continuous stamping using a progressive die. After stamping, the product needs to be separated from the strip using a stamping blanking mechanism. However, the stamping blanking mechanisms provided in the prior art separate the product from the strip by hard stamping. This method is prone to causing burrs due to tearing, resulting in a low product qualification rate and failing to meet the production needs of enterprises.

[0004] To address the aforementioned problems, this application discloses a floating stamping blanking structure. Utility Model Content

The guide groove has an arc-shaped cutting edge on the side away from the second material discharge groove. The horizontal part of the mountain-shaped floating block is movably inserted into two limiting grooves. The two vertical blocks on both sides of the mountain-shaped floating block are located outside the upper pad block and the lower pad block, respectively. The middle vertical block of the mountain-shaped floating block is movably inserted into the guide groove. The middle vertical block of the mountain-shaped floating block has a first arc-shaped cutting protrusion that can be movably placed in the arc-shaped blade on the side away from the second material drop groove. The feeding punch is movably mounted above the upper pad block and cooperates with the middle vertical block of the mountain-shaped floating block. A second arc-shaped cutting protrusion is formed on one side of the feeding punch, corresponding to the first arc-shaped cutting protrusion.

[0007] More preferably, the two vertical blocks on both sides of the mountain-shaped floating block each have outwardly extending steps on one side for cooperating with the upper pad block and the lower pad block.

[0008] More preferably, the lower pad has several floating pins inside that are connected to the transverse part of the mountain-shaped floating block.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0019] To address the issue that existing technologies all rely on hard stamping to achieve... Figure 1 The product shown is separated from the conveyor belt during stamping. This can easily cause burrs due to tearing, resulting in a low product yield. (Refer to...) Figures 2-4 As shown, this application discloses a floating stamping blanking structure, including a lower pad block 10, an upper pad block 20, a mountain-shaped floating block 30, and a blanking punch 40; The lower pad 10 has a first material drop groove 11 inside, and limit grooves 12 are respectively opened on the opposite sides of the lower pad 10. The second material drop groove 21 and the guide groove 22 form a T-shaped structure. The upper pad 20 is located above the lower pad 10, and the upper pad 20 has a second material discharge groove 21 corresponding to the first material discharge groove 11 and a guide groove 22 connected to the second material discharge groove 21. By inserting the horizontal part of the mountain-shaped floating block 30 into the two guide grooves 22, the mountain-shaped floating block 30 can be limited to float downward. The guide groove 22 has an arc-shaped knife edge 23 on the side away from the second material discharge groove 21. The horizontal part of the mountain-shaped floating block 30 is movably inserted into two limiting grooves 12. The two vertical blocks on both sides of the mountain-shaped floating block 30 are located outside the upper pad block 20 and the lower pad block 10, respectively. When the horizontal part of the mountain-shaped floating block 30 moves upward and is blocked by the upper pad block 20, it means that the upper pad block 20 no longer floats upward. In other words, the upper pad block 20 can limit the upward floating of the mountain-shaped floating block 30. The middle vertical block of the mountain-shaped floating block 30 is movably inserted into the guide groove 22. The middle vertical block of the mountain-shaped floating block 30 has a first arc-shaped cutting protrusion 31 that can be movably placed in the arc-shaped blade edge 23 on the side away from the second dropping groove 21. The blanking punch 40 is movably and height-adjustable above the upper pad block 20 and cooperates with the middle vertical block of the mountain-shaped floating block 30. Specifically, the blanking punch 40 is driven to rise and fall by the upper die of the stamping die, and a second arc-shaped cutting protrusion 41 corresponding to the first arc-shaped cutting protrusion 31 is formed on one side of the blanking punch 40. refer to Figure 5 As shown, in specific implementation, the material strip containing the product passes above the upper pad block 20. After it reaches the position, the discharge punch 40 descends and presses down on the product and cooperates with the middle vertical block of the mountain-shaped floating block 30, so that the second arc-shaped cutting protrusion 41 cooperates with the arc-shaped blade 23 to cut the product off the material strip, and the cut product will flow out along the second discharge groove 21 and the first discharge groove 11.

[0020] In one preferred embodiment, the present application has outwardly extending steps 33 on one side of each of the vertical blocks on both sides of the mountain-shaped floating block 30 for cooperating with the upper pad block 20 and the lower pad block 10. When the feeding punch 40 presses down on the mountain-shaped floating block 30, the blocks on both sides of the mountain-shaped floating block 30 will move along the upper pad block 20 and the lower pad block 10, thereby ensuring the stability of the mountain-shaped floating block 30 in raising and lowering.

[0021] In order to enable the mountain-shaped floating block 30 to rise and fall, this application provides several floating pins 50 inside the lower pad block 10 to connect with the horizontal part of the mountain-shaped floating block 30. In this way, after the feeding punch 40 is reset, the mountain-shaped floating block 30 can be automatically reset, which facilitates the continued stamping and feeding of subsequent products.

[0022] In order to guide the product to fall, this application provides a falling chute 32 on the side of the mountain-shaped floating block 30 facing the first falling chute 11 and the second falling chute 21. When the feeding punch 40 and the arc-shaped blade 23 cooperate to cut the product off the material strip, the product will flow outward along the falling chute 32.
