Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a riveting tool for sheet metal processing. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, folding, welding, riveting, splicing, etc. Sheet metal parts are products processed by this process. Sheet metal parts have been widely used in the fields of electronics, communications, automobile industry, medical equipment, etc. For example, sheet metal parts are an indispensable component in electronic products such as computer cases, mobile phones, and MP3s. When riveting sheet metal, it is necessary to work with the corresponding tooling.

[0003] For example, the Chinese patent "A riveting tool for combining sheet metal parts and nuts" with announcement number CN220679258U includes a box body, a plurality of positioning blocks are fixedly connected to the top of the box body, a plurality of riveting blocks are fixedly connected to the top of the box body, a disengagement block is slidably connected to the top of the positioning block, a stabilizing block is fixedly connected to the bottom of the outer wall of the disengagement block, a connecting block is fixedly connected to the bottom of the stabilizing block, a spring is fixedly connected to the top of the stabilizing block, a rotating wheel is rotatably connected to the bottom of the connecting block, a plurality of electric push rods are fixedly connected to the left side of the interior of the box body, and a parallel block is fixedly connected to the output end of the electric push rod.

[0004] Although the above-mentioned existing technology can realize the riveting of sheet metal, in actual use, on the one hand, the sheet metal is prone to position displacement when docking, and the operator is required to stack the two sheet metals together when docking the sheet metal, which causes the sheet metal to move and shift during manual operation, thereby affecting the riveting quality. On the other hand, the adaptability of the sheet metal clamping mechanism is not good enough. When riveting the sheet metal, a clamping mechanism that matches the size of the sheet metal part is required to fix it, resulting in the need to replace the clamping mechanism when processing different sheet metal parts, thereby reducing the adaptability of the clamping mechanism to the sheet metal parts. Therefore, it does not meet the existing needs. In this regard, we propose a riveting tool for sheet metal processing. Utility Model Content

[0005] The utility model aims to provide a riveting tool for sheet metal processing, so as to solve the problems in the above-mentioned background technology that sheet metals are prone to positional deviation during docking and the sheet metal clamping mechanism has poor adaptability.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a riveting tool for sheet metal processing, comprising a frame, an operating table is fixedly arranged on the upper end of the frame, a base is arranged above the operating table, support rods are fixedly arranged at the four corners of the lower end of the base, and the lower ends of the support rods are fixedly connected to the operating table; and also includes:

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can make the sheet metal parts more accurate when docking through the servo motor and the lead screw. When the riveting operation is performed, the sheet metal parts have been squeezed and fixed. At this time, the servo motor is turned on, and the power supply directions of the servo motors on both sides are opposite. The lead screw is driven to rotate through the output shaft of the servo motor, and the moving block is driven to move in the horizontal direction through the thread on the outside of the lead screw, and the moving blocks on both sides move toward each other. During the movement of the moving block, the mounting table is driven to move until the sheet metal part moves to the riveting point directly above the riveting groove, and the lower end of the sheet metal part contacts the rubber gasket, thereby improving the accuracy of the sheet metal part during movement.

[0017] 2. The utility model can clamp and fix sheet metal parts of different sizes through the second hydraulic telescopic device and the extrusion plate. Before the riveting operation is performed, the sheet metal part is first placed on the mounting table, and then the first hydraulic telescopic device is turned on to extend the telescopic end of the first hydraulic telescopic device. The extension and retraction of the telescopic end of the first hydraulic telescopic device drives the fixed plate together with the extrusion plate to move in the vertical direction until the extrusion plate moves to a suitable position. Finally, the second hydraulic telescopic device is turned on to extend the telescopic end of the second hydraulic telescopic device. The extension of the telescopic end of the second hydraulic telescopic device moves the extrusion plate toward the center of the mounting table until the rubber strip on the extrusion plate contacts and squeezes the sheet metal part, so that the sheet metal part is fixed on the mounting table, thereby improving the adaptability of the clamping mechanism to sheet metal parts of different sizes.

[0018] 3. The utility model can provide support for sheet metal parts during riveting through the riveting groove and rubber gasket. During the riveting operation, the sheet metal parts have been stacked and fixed. At this time, the sheet metal parts are riveted by the riveting head. When the riveting head moves downward and squeezes the sheet metal parts, the rubber gasket at the lower end of the sheet metal parts is squeezed and deformed. At the same time, part of the rivet structure falls into the riveting groove. When the riveting is completed, the deformed rubber gasket is reset and the sheet metal part is restored to its original position. The rubber gasket reduces the impact and squeezing of the sheet metal parts, thereby reducing the damage of the sheet metal parts during riveting. BRIEF DESCRIPTION OF THE DRAWINGS
