Automobile seat backrest grid forming mechanism

Abstract

An automobile seat backrest grid forming mechanism comprises a frame, a forming jig, a longitudinal moving assembly, two groups of first transverse moving assemblies, two groups of second transverse moving assemblies and a driving mechanism. The forming jig comprises five rows of forming modules, wherein the five rows of forming modules sequentially comprise a first forming module to a fifth forming module from one side to the other side in the transverse direction, and the third forming module is fixedly arranged on the rack. The two groups of first transverse moving assemblies are respectively connected with the first forming module and the fifth forming module and are used for driving the first forming module and the fifth forming module to transversely move in a manner of being close to or far away from each other. The two groups of second transverse moving assemblies are respectively connected with the second forming module and the fourth forming module and are used for driving the second forming module and the fourth forming module to move together with the longitudinal moving mechanism and move transversely in a manner of being close to or far away from each other. The driving mechanism is used for driving the longitudinal moving assembly, the first transverse moving assemblies and the second transverse moving assemblies to move. The automobile seat backrest grid formingmechanism has the advantages of high automation degree, high forming speed and wide application range.

Description

technical field [0001] The invention relates to the mesh manufacturing technology of the seat back of an automobile. Background technique [0002] The backrest grid of the car seat is arranged in the backrest of the car seat, and can elastically support the back of the driver and passengers. The structure of the common car seat back grid before and after molding is as follows: figure 1 and figure 2 shown. As shown in the figure, a common car seat back grid 9 includes two columns of vertical steel wires 91 and multiple rows of horizontal steel wires 92 . Both ends of each row of horizontal steel wires 92 are respectively wound and fixed on two columns of vertical steel wires 91, and a vertical positioning plastic tube 93 is also provided between the two columns of vertical steel wires 91, through which multiple rows of horizontal steel wires 92 pass. Position the plastic tube 93 . The horizontal steel wire 92 before forming is straight, and the formed horizontal steel w...

AI Technical Summary

Problems solved by technology

[0003] At present, the forming of the bending portion 921 on the transverse steel wire 92 is completed by manual operation with the help of a mold. This manual operation method is labor-intensive and low in work efficiency, and cannot meet the needs of mass production.
