[0002] At present, high-strength steel and ultra-high-strength steel have well realized the lightweight of vehicles, improved the collision strength and safety performance of vehicles, and thus become an important development direction of vehicle steel. However, with the improvement of the sheet strength, the traditional cold stamping process is prone to cracking during the forming process and cannot meet the processing requirements of high-strength steel plates. In the case of unable to meet the forming conditions, the hot stamping forming technology of ultra-high-strength steel plates has been gradually studied internationally.
[0003] When stamping metal, stamping dies are required. However, when some existing stamping dies are in use, the depth inside the stamping die groove is a fixed depth, and thus the stamping depth cannot be well adjusted. As a result, when stamping workpieces with different depths in the later stage, the stamping dies need to be replaced, which causes inconvenience in stamping.
[0004] In view of the above problems, a stamping die with adjustable stamping depth is proposed. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A stamping die with adjustable stamping depth includes a stamping die block. A stamping die groove is formed in the stamping die block. A lifting block is slidably connected inside the stamping die groove. A bidirectional threaded rod is rotatably connected inside the stamping die block. Two moving seats are threadedly connected to the surface of the bidirectional threaded rod. Support rods are rotatably connected inside both of the two moving seats. Two connecting rotating seats are installed at the bottom of the lifting block. One end of each of the two support rods is rotatably connected to one of the two connecting rotating seats respectively. One end of the bidirectional threaded rod is fixedly installed with a connecting rotating shaft, and one end of the connecting rotating shaft rotatably penetrates through the stamping die block and extends to the outside of the stamping die block.
[0007] Preferably, the threads on the surface of the bidirectional threaded rod are arranged in the opposite direction, and the two moving seats are located at the opposite threads of the bidirectional threaded rod.
[0008] Preferably, a crank is fixedly installed at one end of the connecting rotating shaft.
[0009] Preferably, four fixed guide rods are fixedly installed inside the stamping die block, and connecting pieces are slidably connected to the four fixed guide rods. The four connecting pieces are fixedly connected to the surface of the lifting block.
[0010] Preferably, a fixed shaft is fixedly installed on the stamping die block, and a rotating ring is rotatably sleeved on the surface of the fixed shaft.
[0011] Preferably, a torsion spring is arranged between the fixed shaft and the rotating ring. One end of the torsion spring close to the rotating ring is fixedly connected to the rotating ring, and the other end of the torsion spring far from the rotating ring is fixedly connected to the fixed shaft.
[0012] Preferably, a handle is fixedly installed on the rotating ring.
[0013] Preferably, a pawl is fixedly installed on one side of the rotating ring, a ratchet wheel is fixedly sleeved on the connecting rotating shaft, and the pawl is meshed with the ratchet wheel.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] (1). For this stamping die with adjustable stamping depth, the rocking handle drives the connecting rotating shaft to rotate, which in turn drives the bidirectional threaded rod to rotate, causing the two moving seats to move relative to each other, and then one end of the two support rods to move relative to each other. Further, the opposite ends of the two support rods move upward, enabling the lifting block to slide inside the stamping die groove. This facilitates adjusting the depth of the stamping die groove, is convenient for adjusting according to the usage requirements, improves the convenience of adjusting the depth of the stamping die groove, and is convenient for adjusting according to the stamping depth.
[0016] (2). For this stamping die with adjustable stamping depth, when the connecting rotating shaft rotates, it drives the ratchet wheel to rotate, which in turn squeezes the pawl, causing the rotating ring to rotate around the fixed shaft and deforming the torsion spring. When the pawl aligns with the ratchet tooth groove on the ratchet wheel, the pawl and the rotating ring are reset by the torsion of the torsion spring, thereby fixing the connecting rotating shaft. This is convenient for fixing the connecting rotating shaft, preventing the connecting rotating shaft from automatically rotating, improving the adjustment accuracy, and enhancing the stability of the device during use.
