Description

Technical Field

[0001] The utility model relates to the technical field of automobile component manufacturing, in particular to an intelligent automobile seat foam punching device. Background Art

[0002] Car seat sponge foam is a polyurethane high-resilience foam that can provide drivers and passengers with stable high load-bearing capacity and comfort. The seat foam inside a car includes the front seat, front backrest, rear seat, rear backrest, headrest, etc. The different sizes and shapes correspond to different model requirements, and corresponding molds need to be designed for foaming production. The seat foams of different models are also different. Therefore, seat manufacturers often assemble the required molds online through production plans and manufacture various foam products through turntable production lines. Two adjacent molds are usually placed in one position, which we call a workstation.

[0003] After searching, a patent with publication number CN210616733U discloses a handheld foam punching device. First, after holding the handle with hand, the operation of the motor is controlled by the controller. The motor is connected to the first gear through a gear set. The first gear is sleeved at the bottom end of the screw rod, so that the screw rod rotates clockwise to mesh with the threaded sleeve on the inner side of the connecting block. Under the limiting action of the fixed rod, the connecting block is squeezed downward so that the cutter head fits on the cutter groove. Similarly, when the motor is controlled to rotate counterclockwise, the connecting block is lifted upward, and the upper side of the cutter head is threadedly connected to the inner side of the fixed screw sleeve.

[0004] The existing equipment uses a rotating spiral cutter head for punching. However, due to the soft texture of the seat foam, misalignment occurs during rotational punching and there is a large difference in hole diameters. Therefore, we propose an intelligent car seat foam punching device to solve the above problems. Utility Model Content
