Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a positioning plate mechanism with adjustable support height. Background Art

[0002] With the rapid development of the automotive industry, the production frequency of stamping machines has become increasingly faster. For plates that require deep drawing, due to gravity, the plates will collapse when placed on the blank holder. When the collapse exceeds a certain level, it will seriously affect the formability of the product and the sensitivity of the sensor. Currently, this problem is mostly solved by using support positioning plates.

[0003] However, the height of the existing mold support positioning plate cannot be adjusted, and it cannot meet the drawing requirements of different sheet metal parts, which affects the efficiency of mold debugging. For example, patent CN207629023U discloses a drawing die support positioning mechanism, which includes a bracket body, a positioning block, a support block and an adjustable reset device. An adjustment block for adjusting the position and rotation direction is provided directly below the bracket body, and a positioning block for positioning is installed on the side wall of the bracket body. The support block is rotatably connected to the top of the bracket. The support block includes a support end for supporting and a reset end for maintaining the level. An adjustable reset device is provided at the reset end of the support block; it can only be moved back and forth for adjustment. Utility Model Content

[0023] The specific implementation of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown, the positioning plate mechanism with adjustable material support height includes a base 1, a positioning vertical plate 2, a material support block and an adjustment block 4 that can be adjusted up and down along the positioning vertical plate; the lower end of the positioning vertical plate is fixed on the base, the material support block is arranged on the positioning vertical plate through a pin structure, and a polyurethane structure 3 is provided at one end of the adjustment block corresponding to the material support block.

[0025] The base 1 is a flat plate structure, the lower end of the positioning vertical plate is welded to the base, and a support block 5 is provided between the base and the positioning vertical plate to improve the structural strength; a fixing hole is provided on the base, and the fixing hole is a waist-shaped hole; the installation position of the entire mechanism can be fine-tuned.

[0026] A set of axial holes that match the rotating pins are arranged side by side in the vertical direction on the positioning vertical plate 2. The height position of the rotating pins can be adjusted as needed, thereby adjusting the height position of the supporting block.

[0027] Furthermore, the pin structure includes a rotating pin 6, a washer 7 is provided at one end of the rotating pin, and a cotter pin 8 is provided at the other end of the rotating pin; other existing structures can also be used; the structural design is reasonable, which is conducive to the disassembly and installation of the rotating pin for position adjustment.

[0028] The supporting blocks are arranged in a group side by side, and a group of supporting blocks is arranged on the same rotating pin; a group of supporting blocks includes supporting blocks I9, supporting blocks II10 and supporting blocks III11 arranged side by side and spaced apart, which can be adjusted synchronously and have a compact structure.

[0029] A group of adjustment holes are arranged on one side of the positioning vertical plate in the up-down direction, and positioning holes are arranged on the adjustment block corresponding to the adjustment holes; the axial direction of the shaft hole is perpendicular to the axial direction of the adjustment hole, and the structure is compact.

[0030] Furthermore, an open slot is provided in the middle of one side of the adjustment block, the positioning vertical plate is located in the open slot, and the positioning hole on the adjustment block is arranged corresponding to the open slot, resulting in a compact structure;

[0031] The adjustment block is provided with polyurethane structures at symmetrical positions on both sides of the positioning vertical plate. The polyurethane structures can be block-shaped or columnar, preferably columnar. The lower end of the columnar polyurethane is embedded in the adjustment block. The two columnar polyurethanes are symmetrically arranged, and the structure is stable and reliable.

[0032] The base of the utility model mechanism, the support block and the lower end of the positioning vertical plate are welded, and the others are locked together by bolts. Finally, the assembly is directly mounted on the pressure ring for use.

[0033] When the mold is closed, the support positioning structure on the blank holder is released, the polyurethane is not compressed, and the support block is in a lifted state through the turn pin. The upper mold moves downward with the upper table of the machine tool. When the panel contacts the support positioning structure, the support block begins to squeeze the polyurethane, causing the polyurethane to begin to compress until it is compressed to the bottom dead point of the mold. This stage does not affect the molding of the panel.

[0034] When the mold is opened, the blank holder pushes up a stroke, the panel is placed on the adjustable support positioning structure, the polyurethane is compressed, and the support block is in a compressed state through the turn pin. The height of the adjustment block can be adjusted up and down according to the actual situation on site to adjust the height of the support positioning structure, so that the positioning of the panel can be quickly debugged and completed.

[0035] The positioning plate mechanism of the utility model has a reasonable structural design and is easy to adjust up and down. It can be adjusted according to the drawing requirements of different sheet materials. The structure occupies less space than other mechanisms. It also has a simple structure, is easy to maintain, saves time and effort, and has relatively low cost.

[0036] The above is only an illustration of a preferred embodiment of the present invention. The above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0037] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
