Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal flattening device for sheet metal processing. Background Technology

[0002] Sheet metal processing is a manufacturing process that involves processing thin metal sheets into parts or products of various shapes through various techniques, including shearing, punching, bending, welding, riveting, splicing, and forming. It is widely used in many fields such as machinery manufacturing, automobile manufacturing, aviation, electronics, and building decoration.

[0003] During the processing of sheet metal parts, internal stress accumulates. The heat input during the cutting process exacerbates warping, causing the outer side of the sheet metal parts to bend. During the flattening operation, due to the springback characteristics of the sheet metal parts themselves, the pressure distribution is uneven during mechanical flattening. The force is small near the edges and corners, making them prone to springback and resulting in poor flattening effect. There is room for technical improvement. Summary of the Invention

[0004] This invention aims to solve the aforementioned technical problem that, due to the inherent springback characteristics of sheet metal parts, uneven pressure distribution during mechanical flattening easily leads to springback, and provides a sheet metal flattening device for sheet metal processing.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a sheet metal flattening device for sheet metal processing, including an operating table, on which a lower mold is provided; a top plate is provided on the operating table, and several support columns are provided between the top plate and the operating table; further comprising:

[0006] A flattening structure includes a drive cylinder fixedly mounted under the top plate, and an upper mold is provided at the output end of the drive cylinder.

[0007] The auxiliary structure includes a rectangular frame located outside the drive cylinder. The outer side of the rectangular frame is provided with several adjustable length connecting plates. Each connecting plate has an adjusting rod at the end away from the rectangular frame. Each adjusting rod is hollow inside. Each adjacent adjusting rod is connected to an L-shaped support rod. Each support rod has a fixing plate at its corner. Each fixing plate has an electric push rod. The output end of each electric push rod extends out of the fixing plate and has an auxiliary pressure plate. Each auxiliary pressure plate can contact the upper mold.

[0008] Furthermore, the sheet metal part is located between the upper and lower molds.

[0009] Furthermore, the connecting plate includes a hollow plate connected to the rectangular frame, and an extension plate is slidably provided at the end of the hollow plate away from the rectangular frame.

[0010] Furthermore, the adjusting rod is provided with threaded holes, and each threaded hole is threaded with a locking bolt, the lower end of which contacts the corresponding support rod.

[0011] Furthermore, the bottom surface of each auxiliary pressure plate is provided with anti-slip protrusions;

[0012] Furthermore, the corners of the upper mold and the auxiliary pressure plate are all chamfered.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] Based on mechanical flattening, auxiliary pressure plates are added at the four corners of the upper mold to increase the mechanical pressure at the corners and improve the uniformity of pressure distribution, thereby reducing the phenomenon of corner springback.

[0015] The edges of both the upper mold and the auxiliary pressure plate are chamfered to reduce stress concentration.

[0016] The auxiliary pressure plate can be adjusted to apply force, making it suitable for sheet metal parts of different sizes. Attached Figure Description
