Embodiment 1

[0068] Embodiment 1: as Figure 2 to Figure 6 As shown, the locomotive door is a corridor door 1, and the door body skeleton 7 includes a skeleton frame body 8, a window frame body 9 located in the skeleton frame body 8 and close to the upper part of the skeleton frame body 8, and a In the frame body-8 and near the lower beam-10 at the lower part of the frame body-8, a corridor door sealing strip around the entire circumference of the frame body-8 is also arranged on the outer peripheral surface of the frame body-8 11. Window frame one 9 is used for installing glass windows, one side of window frame one 9 is connected with the inner side of skeleton frame one 8 through crossbeam one 12, and the other side of window frame one 9 is through crossbeam two 13 It is connected to the other side of the skeleton frame 8, one end of the lower beam 10 is connected to the inner side of the skeleton frame 8, and the other end of the lower beam 10 is connected to the other side of the skele...

Embodiment 2

[0086] Embodiment 2: as Figure 11 As shown, compared with Embodiment 1, the difference is that: a transverse reinforcing rib 53 is provided between the lock body projection one 14 and the lock body projection two 15, and the window frame body one 9 and the lower beam one 10 A longitudinal reinforcing rib 1 54 is arranged between them. The transverse ribs one and the longitudinal ribs one mainly strengthen the panel and further increase the strength of the panel. In this embodiment, the first transverse reinforcing rib and the first longitudinal reinforcing rib are arranged on one side close to the inner panel, and mainly play a role in strengthening the strength of the inner panel.

Embodiment 3

[0087] Embodiment 3: as Figure 12 to Figure 14 As shown, compared with Embodiment 1, the difference is that: the locomotive door is an entrance door, and the door body skeleton includes a skeleton frame body 2 55 and is located in the skeleton frame body 2 55 and is close to the skeleton frame body 2 55 The upper cross beam 56 at the top, one end of the upper cross beam 56 is connected with the inner side of the skeleton frame body two 55, and the other end of the upper cross beam 56 is connected with the inner other side of the skeleton frame body two 55; The middle position of 55 and is positioned at the inner side of skeleton frame body 2 55 and is provided with lock body projection 3 57, between lock body projection 3 57 and the inner other side of skeleton frame body 2 55, middle crossbeam 1 is arranged 58, at the lower part of the skeleton frame body two 55 and on the inner side of the skeleton frame body two 55, a lock body projection four 59 is arranged, and on the ot...

Abstract

The invention discloses a manufacturing method of a rapid power concentrated rail motor coach motor car carbon fiber locomotive door. According to the manufacturing method, an outer panel, an inner panel and a door body framework are manufactured through carbon fiber materials in a die pressing integrated molding manner and are then pasted together. Pasting includes the steps that (1) the position between the outer panel and the door body framework is smeared with epoxy resin adhesive; (2) the outer panel and the door body framework are clamped together and are then sent to an oven to be backed, and therefore the outer panel and the door body framework are completely pasted; (3) an acoustic insulating material is taken out from the oven to be placed into the door body framework; (4) the position between the inner panel and the door body framework is smeared with epoxy resin adhesive; (5) the outer panel, the inner panel and the door body framework are clamped together to form a locomotive door semi-finished product, and then the locomotive door semi-finished product is sent to the oven to be baked; and (6) after baking is completed, the locomotive door semi-finished product is taken out from the oven and is subject to follow-up machining treatment, and a finished product is formed. According to the manufacturing method, the light design requirement is met, and the manufacturing accuracy is high.

Description

technical field [0001] The invention relates to a manufacturing method of a locomotive door of a fast power concentrated EMU power car, in particular to a manufacturing method of a carbon fiber locomotive door of a fast power concentrated EMU power car. Background technique [0002] The power-concentrated train is the most traditional mode of operation in railway transportation. A power locomotive pulls several unpowered vehicles and runs on the track. In addition to being used in passenger transport, it is often used in freight and military purposes. The locomotive doors on the power centralized trains shall meet the relevant design requirements, and the locomotive doors shall be able to work normally under the following operating conditions: a. The lowest temperature is -40°C and the highest is 70°C; b. The average maximum relative temperature of the wettest month Humidity is less than or equal to 95%; c, rain, snow, wind, sand, coal dust, sunlight and light radiation and...
