Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention. FIG. 1 is a schematic structural view of the present invention; fig. 2 is a schematic structural view of a lower die of the present invention.

As shown in fig. 1, an elevator door switch elastic sheet forming device comprises a base 1, a cutter 2, a bevel cutter 3, a fixed core rod 4, a central die 5, a guide block 6, a side plate bevel 7, a punching cutting part 8, an upper die 9 and a lower die 10, wherein the upper die 9 is positioned right above the lower die 10, the lower die 10 is provided with the side plate bevel 7 and the punching cutting part 8, the bottom of the upper die 9 is fixed with a punch rod and a cutting cutter which are used for matching with the punching cutting part 8, the base 1 is connected with the cutter 2 and the bevel cutter 3 in a sliding fit manner, the base 1 is provided with the central die 5 and the guide block 6, the fixed core rod 4 is vertically fixed on the end surface of the base 1, and the guide block 6 is internally provided with a through groove for passing a material belt.

As shown in fig. 2, the side plate bending part 7 is composed of a bending block 71, a push rod 72, a spring 73 and a sliding groove 74, the sliding groove 74 is arranged on the lower die 10, the bending block 71 is matched in the sliding groove 74, the bending block 71 is fixed at the top end of the push rod 72, a limiting plate is fixed at the tail end of the push rod 72, and the spring 73 is arranged between the limiting plate and the lower die 10.

The lower die 10 is provided with a material belt linear flow passage 11, and the material belt linear flow passage 11 is perpendicular to and communicated with the sliding groove 74.

The punching and cutting part 8 consists of a punching hole 81 and a punching groove 82, the lower die 10 is provided with the punching hole 81 used for matching with a punching rod and the punching groove 82 used for matching with a cutting knife body, and a plurality of stop blocks 13 are distributed above the material belt linear flow passage 11. When the material belt moves along the material belt straight flow channel 11, the two rows of stop blocks 13 block the left side and the right side of the material belt at the upper part, so that the material belt is prevented from upwards separating from the flow channel when being subjected to stress processing.
