Problems solved by technology

[0004] One is that the connection between the reinforcing plate and the mirror elevator door panel is not stable, which may easily cause the reinforcing plate to fall off
[0005] The second is that the way of pasting makes the overall operation of the elevator not good. The main problem is that noise and resonance will occur during the operation of the elevator.
[0006] The third is that the glue or double-sided tape used for pasting will pollute the environment in the car, which is especially harmful to the health of elevator production workers.

Embodiment 1

[0031] Such as Figure 1 to Figure 3 As shown, the traceless welding method of a kind of mirror elevator door panel and galvanized reinforcing plate of the present invention is like this: by setting the channel 1 that is used for the zinc vapor that welding produces to realize circulation on galvanized reinforcing plate 5, and in galvanized The end face of the channel 1 of the reinforcing plate 5 clamps and welds the back of the galvanized reinforcing plate 5 and the mirror elevator door panel 6 by means of water cooling and heat dissipation, so as to realize the seamless welding of the mirror elevator door panel 6 and the galvanized reinforcing plate 5 .

[0032] Specifically, the above-mentioned channel 1 for the circulation of the zinc vapor generated by welding is provided on the galvanized reinforcing plate 5, and the galvanized reinforcing plate 5 and the mirror elevator door panel 6 are connected at the end face of the channel 1 of the galvanized reinforcing plate 5. Th...

Embodiment 2

[0044] The only difference between this embodiment and Embodiment 1 is that in the actual production process, three or more strips can be rolled on the end faces of the convex surface of the galvanized reinforcement board on both sides of the convex surface of the galvanized reinforcement board according to the size of the galvanized reinforcement board and the mirror elevator door panel. The indentation of two adjacent indentations can be used as a channel, and the welding of the galvanized reinforcement plate and the mirror elevator door panel can be realized on the end face of each channel during production.

[0045] Other structures of this embodiment are consistent with Embodiment 1.

Embodiment 3

[0047] The difference between this embodiment and the first embodiment is that in order to improve the stability of the welding, more than two welding spots can be used on the end surface of the channel to realize welding during processing.

[0048] Other structures of this embodiment are consistent with Embodiment 1.

Abstract

The invention provides a seamless welding method for a mirror-surface elevator door panel and a galvanized reinforcing plate. The method includes the steps that a channel used for achieving the circulation of zinc vapor generated by welding in the galvanized reinforcing plate is arranged on the galvanized reinforcing plate, and clamping welding is conducted on the reverse sides of the galvanized reinforcing plate and the mirror-surface elevator door panel on the end face of the channel of the galvanized reinforcing plate by using the water-cooling heat dissipation means so as to achieve seamless welding of the mirror-surface elevator door panel and the galvanized reinforcing plate. By means of the method, after being welded with the galvanized reinforcing plate, the mirror-surface elevator door panel has no seams formed in the front surface and has no color change, therefore, the appearance of the front surface of the mirror-surface elevator door panel is not affected, the galvanized reinforcing plate and the mirror-surface elevator door panel are installed stably and firmly without affecting the whole operation of an elevator, at the same time, environmental pollution in an elevator car is not caused, and the large-scale high-efficiency elevator car production is easily achieved.

Description

technical field [0001] The invention relates to the technical field of industrial welding, and more specifically relates to a method for seamlessly welding a mirror elevator door panel and a galvanized reinforcing plate. Background technique [0002] At present, in the elevator industry, there are mirror elevator door panels made of stainless steel in the general elevator car, which not only serves as a cosmetic mirror, but also enables the disabled to expand their vision when using it, such as facilitating the steering of wheelchairs and entering and exiting the car. In order to increase its strength, it is necessary to add a reinforcing plate to the back of the mirror elevator door panel. [0003] Because the mirror elevator door panels are relatively thin, the use of welding to fix the reinforcing plate and the mirror elevator door panels will directly affect the appearance of the front of the mirror elevator door panels. Therefore, most of the reinforcing panels in the p...
