Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a high-precision punching mold for processing a U-shaped frame of a swivel chair. Background Art
[0002] Swivel chairs are common furniture in work and life. They are popular because of their flexibility and comfort. They mainly include a base and a seat. Armrests and backrests are arranged on the basis of the seat to improve comfort. The armrests and backrests of traditional swivel chairs are of two styles: non-integrated and integrated. The non-integrated armrests and backrests rely on materials, processing technology, and structural design to ensure a certain strength. The integrated armrests and backrests can also provide structural strength support to each other through the connection between the two. However, the strength of both designs is limited. Deformation is inevitable during long-term use, and it is particularly obvious at the backrest position. Relevant technicians have provided The design idea of setting a U-shaped frame between the armrest and the backrest is to provide high-strength support for the armrest and the backrest through the U-shaped frame. The only problem is that the position where the U-shaped frame is connected to the armrest and the backrest needs to be punched for connection. The position where it is connected to the backrest has a certain curvature. When punching, the U-shaped frame must be kept stable and the punching position must be as accurate as possible to ensure the punching accuracy. Traditional punching equipment generally finds it difficult to meet these two requirements at the same time. Based on this situation, how to keep the U-shaped frame stable and make the punching position as accurate as possible to ensure the punching accuracy has become an increasingly urgent problem that relevant technical personnel need to solve.

The front slider 15 moves forward steadily until the slot 20 at the front of the rear clamping seat 10 fits with the U-shaped frame 6. At this time, the rear clamping seat 10 and the front clamping seat 9 cooperate to clamp the U-shaped frame 6, and then the rear pressure block 13 pushes the rear slider 16 to move forward steadily. The end of the punch needle 18 passes through the through holes in the middle of the rear guide block 19 and the front guide block 21 in turn, and accurately punches the U-shaped frame 6 at the predetermined position. The punched waste falls through the waste hole 22, so that the upper die seat 1 moves vertically upward until it is reset, and the U-shaped frame 6 that has been punched is taken away, and a high-precision punching process can be completed.
