Description

Technical Field

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

[0002] A riveting press machine (also known as a riveting machine, spin riveting machine, riveting assembly machine, or roll riveting machine) is a new type of riveting equipment developed based on the principle of cold rolling. It refers to mechanical equipment that can rivet items together. It solves the problem that some sheet metal parts, after being bent, cannot be directly placed on ordinary inclined cast steel machines for riveting. Riveting press machines have wide applications in sheet metal processing. They are mainly used to press nuts into sheet metal parts to form a strong connection. This connection method has advantages such as minimal deformation, no need for grinding, environmental friendliness, low requirements for the working environment, and stable and reliable connection strength, making it especially suitable for connecting thin plates.

[0003] An existing sheet metal riveting device (application number: CN202322702253.0) features a positioning mechanism between a support plate and a moving plate. It utilizes a riveting machine to facilitate riveting of sheet metal parts. By placing the sheet metal part inside the bottom limiting unit and then activating an electric push rod, the top limiting unit presses against the top of the sheet metal part, thus securing it in place and preventing movement during riveting. This ensures the part remains horizontal, improving the riveting effect. Pulling the limiting rod moves the limiting shell to an appropriate position, allowing the positioning mechanism to secure sheet metal parts of different sizes, enhancing the device's practicality. However, existing sheet metal riveting machines still have the following problems during use: Existing riveting machines press nuts into sheet metal parts on the riveting table. To prevent damage to the riveting table from the pressure, a positioning and pressing port is usually provided on the riveting table. When the sheet metal part is placed on the riveting table, the positioning and pressing port is covered by the sheet metal part. This makes it impossible for the nut to be accurately placed through the positioning and pressing port. The nut needs to be moved repeatedly to allow the pressing block to position and press the nut into the sheet metal part, which causes great inconvenience to the operation and affects work efficiency. Therefore, it is necessary to develop a riveting device for sheet metal processing in the field of existing sheet metal processing equipment. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, conventional riveting machines press nuts into sheet metal parts on the riveting table. To prevent damage to the riveting table caused by the pressure, a positioning and pressing operation port is usually provided on the riveting table. When the sheet metal part is placed on the riveting table, the positioning and pressing operation port is covered by the sheet metal part. This also makes it impossible for the nut to be accurately placed through the positioning and pressing operation port. The nut position needs to be moved repeatedly so that the pressing block can position and press the nut into the sheet metal part, which brings great inconvenience to the operation and affects the work efficiency. This utility model proposes a riveting device for sheet metal processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a riveting device for sheet metal processing, comprising: A sheet metal processing table, wherein a support column is fixedly mounted on the sheet metal processing table; The positioning mechanism includes an operating block, which is fixedly mounted on a support column. A guide port is provided through the operating block, and guide rods are symmetrically fixedly mounted on the guide port. Slider blocks are movably mounted on the two guide rods, and each slider has an assembly port located below the operating block. Connecting rods are symmetrically fixedly mounted on the assembly port, and adjusting blocks are movably mounted on the two connecting rods. Each connecting rod is equipped with a telescopic spring, with both ends of the telescopic springs fixedly mounted to the assembly port and the adjusting block, respectively. A movable port is provided on the side of the slider, communicating with the assembly port. A toggle block is fixedly mounted on the side of the adjusting block, movably mounted to the movable port. An extension block is fixedly mounted on one end of the adjusting block, and a positioning block is fixedly mounted on one end of the extension block, with a positioning port on the positioning block.

[0006] Preferably, the sheet metal processing table is symmetrically and fixedly equipped with support blocks, and the top of the two support blocks is fixedly equipped with a riveting table.

[0007] Preferably, the riveting platform is provided with a positioning and pressing operation port.

[0008] Preferably, the positioning block is located above the riveting table, and the positioning port is located above the positioning pressing operation port.

[0009] Preferably, a bearing plate is fixedly mounted on the support column, a cylinder is fixedly mounted on the bearing plate, and a piston rod is fixedly mounted on the output end of the cylinder.

[0010] Preferably, the piston rod moves through the bearing plate, and a stamping block is fixedly mounted at the bottom of the piston rod, with the stamping block located above the positioning and pressing operation port of the riveting table.

[0011] Preferably, a mounting plate is fixedly mounted on the piston rod, the mounting plate being located below the bearing plate, and an operating plate is fixedly mounted on the top of the slider.

[0012] Preferably, an adjusting rod is movably mounted on the operation panel, and the other end of the adjusting rod is movably mounted to the mounting plate.

[0013] The advantages of this utility model are: This invention utilizes a toggle block to move the toggle block on the movable port, an adjusting block to move on two connecting rods, and a telescopic spring to retract, allowing the sheet metal part to be placed on the riveting table. The sheet metal part covers the positioning and pressing operation port on the riveting table, and the bottom of the positioning block fits against the surface of the sheet metal part. A nut can be placed in the positioning port on the positioning block for positioning. Activating the cylinder causes the piston rod to move the stamping block downwards. Under the action of the adjusting rod, the slider moves the guide rod on the guide port, moving the positioning port on the positioning block away from the nut until the stamping block presses the sheet metal part in. This eliminates the need for repeated calibration of the nut, improving work efficiency. Attached Figure Description
