[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] The prior art (publication number: CN 220072999 U) discloses a stamping die with a replaceable stamping die head, including a die mounting assembly and a stamping assembly, wherein the die mounting assembly includes a mounting column, a first mounting groove, a second mounting groove, a mounting plate, a connecting rod, and a mounting rod, wherein the first mounting groove and the second mounting groove are opened in the mounting column, the first mounting groove is at the top of the second mounting groove, the mounting plate is arranged at the bottom of the mounting column, the connecting rod is arranged at the top of the mounting plate, the connecting rod is located in the second mounting groove, the mounting rod is arranged at the top of the connecting rod, and the mounting rod is arranged in the first mounting groove.

[0004] Although the above patent rotates the relatively close side of the bolt to the inside of the thread groove under the action of the bolt, thereby fixing the connecting rod, thereby facilitating the installation and removal of the die head and facilitating the replacement of the drilling die head, it has the following disadvantages: the bolt needs to be installed and removed with tools, the operation is relatively cumbersome, and the operation steps of the workers are increased, which affects the installation and removal efficiency. Further improvement is needed, so we propose a replaceable stamping die head stamping die. Utility Model Content

[0005] The main purpose of the utility model is to provide a stamping die with a replaceable stamping die head, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A stamping die with a replaceable stamping die head comprises a base plate, a lower die is installed in the middle of the upper end of the base plate, an L-shaped plate is installed at the rear of the upper end of the base plate, a hydraulic cylinder is installed at the upper end of the L-shaped plate, the output end of the hydraulic cylinder movably passes through the upper wall of the L-shaped plate and is fixedly connected to a movable plate, a movable part is commonly installed at the lower left and lower right parts of the movable plate, two symmetrically distributed clamping blocks are slidably connected to the middle of the lower end of the movable plate, a stamping head is commonly arranged between the two clamping blocks, a fixing part is arranged in each of the two clamping blocks, the two fixing parts are symmetrically distributed, and a fixing groove is opened at the left and right ends of the stamping head.

[0008] Preferably, a rectangular groove is formed at one end of the two clamping blocks that are close to each other, and a circular groove is formed in each of the two rectangular grooves.

[0009] Preferably, the fixing component includes a rectangular block, which is arranged in a rectangular groove, a circular plate is fixedly sleeved on the outer surface of the rectangular block, a spring is arranged on one side of the circular plate, and an electromagnet is arranged on the other side of the circular plate, the circular plate and the electromagnet are both located in the circular groove, the spring is located in the rectangular groove, one end of the spring is fixedly connected to the rectangular block, the other end of the spring is fixedly connected to the rectangular groove, and the outer surface of the electromagnet is fixedly connected to the inner cylindrical surface of the circular groove.

[0010] Preferably, the side of the rectangular block away from the spring extends into the fixing groove.

[0011] Preferably, the movable component includes a bearing seat, and two bearing seats are provided. The two bearing seats are respectively installed on the lower left part and the lower right part of the movable plate. A forward and reverse threaded rod is rotatably connected between the two bearing seats. The right side of the forward and reverse threaded rod movably passes through the right side of the right bearing seat and is installed with a knob.

[0012] Preferably, the clamping block is threadedly sleeved on the forward and reverse threaded rods.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The efficiency of installing and removing the punch head can be improved by setting a fixed component. When the punch head needs to be removed, the hydraulic cylinder is controlled to drive the punch head to move downward into the punching slot of the lower die, and the power supply is controlled to stop supplying power to the electromagnet, so that the two electromagnets lose their magnetism and no longer adsorb the two circular plates. The spring drives the rectangular block away from the fixed slot through its own elastic force, and the punch head can be automatically removed. During installation, another punch head that needs to be replaced is placed in the punching slot of the lower die, and the hydraulic cylinder is controlled to drive the clamp block close to the punch head so that the rectangular slot is aligned with the fixed slot. Then, the electromagnet is powered so that the two electromagnets adsorb the two circular plates, and the two circular plates respectively drive the two rectangular blocks to move into the fixed slot to complete the fixation. The operation is simple, no other tools are required, and the operation steps of the workers are reduced;

[0015] 2. By setting the movable parts, it is convenient to clamp the punching heads of different widths. When the punching head is wider, turn the knob, the knob drives the positive and negative threaded rods to rotate, and the positive and negative threaded rods drive the two clamps to move away from each other, so that the clamps can adapt to the punching head, so that the wider punching head can be fixed, which improves the application range of the equipment.

[0025] A rectangular groove 12 is formed at one end of the two clamping blocks 6 that are close to each other, and a circular groove 13 is formed in each of the two rectangular grooves 12 .

[0026] In order to improve the efficiency of installing and disassembling the punch head 7, the punch head 7 is fixed by setting a fixing component 10, and the fixing component 10 includes a rectangular block 102, and the rectangular block 102 is arranged in the rectangular groove 12. The outer surface of the rectangular block 102 is fixedly sleeved with a circular plate 103, a spring 101 is arranged on one side of the circular plate 103, and an electromagnet 104 is arranged on the other side of the circular plate 103. The magnetic force of the electromagnet 104 is greater than the elastic force of the spring 101. The electromagnet 104 is used to drive the circular plate 103 and the rectangular block 102 to move by magnetic force. The circular plate 103 and the electromagnet 104 are both located in the circular groove 13, and the spring 101 is located in the rectangular groove 12.
