Automatic riveting machine for advertising traffic sign board

Abstract

The invention discloses an automatic riveting machine for an advertising traffic sign board. The automatic riveting machine comprises a fixing frame, a buttering installation rod is arranged in the middle of the inner side of the fixing frame, a supporting pneumatic cylinder is installed at the bottom end of the inner side of the fixing frame, and fixing clamps are symmetrically installed on two sides of the buffering installation rod. The automatic riveting machine is scientific and reasonable in structure and safe and convenient to use. An upper punch is pressed downwards through a rivetingpneumatic cylinder to cooperate with a lower punch, and fast riveting operation is realized; and through rotation of a screw, an internal thread sleeve moves under the action of a limiting plate, fastmobile riveting of the upper punch is realized, the riveting efficiency is improved, the labor intensity of workers is reduced, and the forming time of the sign board is shortened. The lower punch ispulled out by pulling a receiving plate in a replacing notch, a new nail cap is placed in a nail cap groove, the nail cap replacing efficiency is improved, and continuous working of the device is guaranteed; and meanwhile, the replacing notch guarantees taking-out of the lower punch, and in cooperation with a baffle, it is avoided that the receiving plate completely enters the fixing frame.

Description

technical field [0001] The invention relates to the technical field of riveting, in particular to an automatic riveting machine for advertising traffic signs. Background technique [0002] With the rapid development of basic equipment such as roads and bridges, other facilities such as billboards and traffic signs around the road are gradually improving. The existing billboards and traffic signs are all types of signs, usually using two or There are multiple pieces, and the plates need to be connected together through the cooperation of corner materials and aluminum profiles. The existing riveting operations are mostly riveted by manual riveting guns. The signboard is large in size, and there are many positions that need to be riveted. The riveting pressure is consistent. It is necessary to manually perform riveting operations repeatedly, which increases the labor intensity of the personnel and reduces the production and molding time of the signs. At the same time, when the ...

Problems solved by technology

[0003] The present invention provides an automatic riveting machine for advertising traffic signboards, which can effectively solve the problem that the existing riveting operations proposed in the above background technology are mostly riveted by manually operated riveting guns. The strength is consistent, and manual riveting operations need to be repeated, which increases the labor intensity of the personnel and reduces the production and molding time of the signs. The relative stress conflict between the plates makes it easy for the sign board to be separated and damaged after riveting. However, riveting guns are used to rivet in the market, which is time-consuming and labor-intensive, and the riveting efficiency is low, which is prone to riveting failure.
