An elevator door panel assembly production line

Abstract

The invention discloses an elevator door sheet assembly production line. By means of the elevator door sheet assembly production line provided by the invention, under the condition that the appearancequality of an elevator door sheet is not affected, the connecting strength between the elevator door sheet and a vertical rib plate can be effectively improved, and therefore the overall strength ofthe elevator door sheet can be guaranteed. The elevator door sheet assembly production line comprises a door sheet conveying device, a punching point welding station, a transverse point welding station and a discharging stacking station. The door sheet conveying device comprises a bottom frame, translational movement guide tracks arranged on the bottom frame and a translational movement sliding table which slides along the translational movement guiding tracks. The punching point welding station comprises a punching point welding mechanism and a punching base plate mechanism. The punching point welding mechanism comprises a lifting flat plate, vertical upper point welding electrodes and vertical punching rods, wherein the vertical upper point welding electrodes and the vertical punching rods are arranged on the lifting flat plate. The punching base plate mechanism comprises a support, a cantilever beam arranged on the support and a punching base plate located on the translational movement sliding table. The transverse point welding station comprises a transverse point welding device. The discharging stacking station comprises a discharging stacking device.

Description

technical field [0001] The invention relates to an elevator door panel production equipment, in particular to an elevator door panel assembly production line. Background technique [0002] The production of elevator door panels usually includes the door panel bending process and the rib plate welding process. The rib plate welding process is to place the reinforcing rib plate on the back of the elevator door panel (such as Figure 8 As shown, the reinforcing ribs generally include an upper rib 6.3, a lower rib 6.4 and a vertical rib 6.2 between the upper rib and the lower rib. The upper rib and the lower rib are located on the upper and lower sides of the elevator door panel The lower two ends), the reinforcing ribs are welded to the back of the elevator door panel by welding equipment, which is used to improve the overall strength of the elevator door panel. At present, a common welding method in the rib plate welding station of the elevator door panel is: place the rib pla...

AI Technical Summary

Problems solved by technology

The current rib plate welding process uses spot welding equipment to weld the reinforced rib plate, and the reinforced rib plate and the elevator door panel are connected by several welding spots. Although the welded spot connection between the reinforced rib plate and the elevator door panel can effectively reduce the appearance quality of the elevator door panel However, at present, there are often poor connection strengths of solder joints between the elevator door panels and the reinforcing ribs, especially between the elevator door panels and the vertical ribs, which often affect the elevator door panels. The strength of the connection with the reinforcement ribs, which in turn affects the overall strength of the elevator door panel
