Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a multi-hole synchronous stamping slide rail sheet die. Background Art

[0002] The slide rail sheet refers to a metal part that is installed on a vehicle seat and used to adjust the front and rear of the vehicle seat. The vehicle seat in the current prior art includes a track installed on the vehicle, namely a male rail, and a track installed on the seat, namely a female rail. The male rail and the female rail are installed with slide rail sheets. The female rail installed with the slide rail sheet is made to slide relative to the male rail through an adjusting device and lock the position of the female rail to achieve the method of adjusting the vehicle seat. The stamping die is a special process equipment for processing materials into parts in cold stamping. It uses a die installed on a press to apply pressure to the material to cause separation or plastic deformation, thereby obtaining a pressure processing method for the required parts. The slide rail sheet needs to be processed using a stamping die.

[0003] In a Chinese patent for a stamping die for automobile slide rail material with a shock-absorbing function (patent number: CN215657365U), the device includes an upper die, an upper die punch, a lower die, a guide sleeve, a guide sleeve slide groove, a guide column and a guide column buffer spring. The upper end of the upper die punch is connected to the lower end of the upper die, the lower die is arranged on the lower side of the upper die, and the lower die corresponds to the upper die. Two groups of guide sleeves are symmetrically installed on the left and right sides of the lower end of the upper die, and a guide sleeve slide groove is opened inside the lower end of the guide sleeve. Two groups of guide columns are symmetrically installed on the left and right sides of the upper end of the lower die, and each group of guide columns is provided with a guide sleeve slide groove. A group of guide post buffer springs are arranged around the outer side of the column circumference, and the lower end of the guide post buffer spring is connected to the upper end of the lower die. By compressing the guide post buffer spring and the elastic force of the guide post buffer spring, the instantaneous pressure formed by punching is buffered, thereby avoiding wear caused by rapid closing of the die and improving the stability of use. However, when the device performs multi-hole stamping processing on the slide rail sheet, there is no positioning mechanism for fixing the slide rail sheet, which makes the slide rail sheet easy to deviate during the stamping process, thereby affecting the quality of the stamping process.
