Description

Technical Field

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

[0002] Riveting equipment, also known as riveting machine, rotary riveting machine, riveting machine, etc., is a mechanical equipment that can rivet objects together with rivets. Riveting machines are mainly used for riveting solid rivets, hollow rivets, and hollow rivets. They can rivet one end of a solid nail into a flat head or a mushroom head, and can also roll a hollow nail into a flanging effect. During the manufacturing process of sheet metal parts, riveting equipment applies pressure to press rivets and other fasteners firmly into sheet metal parts, thereby achieving reliable connection between different sheet metal parts.

[0003] Existing riveting equipment can only handle the riveting task of one sheet metal part at a time, which limits its overall production efficiency.

[0004] For example, a sheet metal riveting processing equipment disclosed in the announcement number CN213887890U has a relatively low production efficiency because the equipment is designed with only one workstation, that is, it can only position and rivet one sheet metal part at a time. When large-scale production is required, this low efficiency may become a bottleneck restricting the production progress. When a riveting task is completed, it is necessary to wait for the next task to be prepared and placed, which increases unnecessary waiting time and reduces the overall work efficiency.

[0005] Therefore, it is necessary to invent a riveting device for sheet metal processing to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a riveting device for sheet metal processing to solve the problem of low production efficiency in the technology.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-6 When using the utility model, first move the riveting device to a suitable position through the universal wheel 2 and place it stably, then connect the riveting device to an external power supply so that the riveting device is powered on and can work, then place the sheet metal parts to be processed on the No. 1 workbench 8 and the No. 2 workbench 9, and ensure that the hole positions of the sheet metal parts coincide with the positioning holes 10, start the device through the electric control box 6, and control the electric telescopic rod 12 to make the clamping plate 13 clamp the sheet metal parts, and control the drive motor 14 to start through the electric control box 6. After the drive motor 14 is started, the rotational motion is converted into the rotation of the reciprocating screw 17 through the meshing of the No. 1 bevel gear 15 and the No. 2 bevel gear 16. The rotation of the reciprocating screw 17 drives the column 3 to move linearly along the body 1 under the guidance of the slide bar 18 and the slide groove 22, so that the column 3 drives the rivet head 5 to move to the corresponding No. 1 bevel gear. Above the workbench 8, the movement range of the column 3 is limited by the No. 1 limit plate 19 to ensure the accuracy of the position of the rivet head 5. Then, the hydraulic cylinder 4 is controlled to lower the rivet head 5 to press the sheet metal. After the riveting is completed, the hydraulic cylinder 4 is controlled by the electronic control box 6 to raise the rivet head 5. Then the drive motor 14 drives the reciprocating screw 17 to move in the opposite direction, so that the column 3 drives the rivet head 5 to move to the corresponding No. 2 workbench 9, and the movement range of the column 3 is limited by the No. 2 limit plate 20 to ensure the accuracy of the position of the rivet head 5. At the same time, the electric telescopic rod 12 on the No. 1 workbench 8 drives the splint 13 to loosen the riveted sheet metal, remove the processed sheet metal from the workbench, and prepare the next sheet metal for processing. Such repeated operations realize the alternating use of the No. 1 workbench 8 and the No. 2 workbench 9, effectively improving the work efficiency.
