The front and rear sides of the lower die table are provided with symmetrically distributed circular grooves. The interior of the circular groove is slidably connected with an extrusion slide column. The opposite ends of the two extrusion slide columns are provided with extrusion balls. The rectangular slot is communicated with the horizontally adjacent circular groove, and the circular groove is communicated with the horizontally adjacent slot. The fastener stamping die is convenient and fast to disassemble and install. The device can also automatically eject the fastener after stamping. The inventor found that the existing technology has the following problems in the process of implementing the utility model: 1. The heating structure of the existing design is relatively traditional and cannot be quickly heated or stopped, which affects the safety and convenience of the operation of the device; 2. The heating structure and stamping structure of the existing design cannot be linked, and need to be operated separately, which is relatively cumbersome to use, and there is a safety hazard in operating the heated fastener.
