Production process of end wall of passenger car

Abstract

The invention provides a production process of an end wall of a passenger car, comprising the following steps: fixing a doorsill locating component, a doorframe locating component and a locating bar in proper places, wherein the doorsill locating component, the doorframe locating component and the locating bar correspond to the dimensions of an end wall; laying a door side plate on the upper surfaces of long worktables; putting a diaphragm post at the inner side of the door side plate, wherein the inner side surface of the diaphragm post props against the outer end surface of the doorframe locating component; putting an end corner post at the outer side of the door side plate, wherein the outer side surface of the end corner post props against the inner side edge of the locating bar; laying a door header and a door upper plate in turn, wherein the door header is positioned between the door side plate and the door upper plate; fixing a doorsill by the doorsill locating component; compressing the door side plate on the long worktables and compressing the door upper plate on the long worktables and a short worktable; and welding the weld seams among the components of the end wall. The production process is ingenious in conception, is simple and convenient to operate, ensures high production efficiency and is suitable for producing the end walls in various dimensions. The production process will be widely applied in the field of rail transit and has good market prospect.

Description

technical field [0001] The invention relates to a production process of a passenger car end wall. Background technique [0002] With the breakthrough of the company's passenger car products in the international market, more and more products that are completely different from the original domestic 25-type passenger cars have appeared, but the number is small (for example: Georgian cars, Malaysian cars, etc.), in the steel structure production Among them, if large-scale assembly welding tools are made for each product, it will not only increase the cost, but also affect the delivery time. Under the market economy, whether it can meet market demand with high quality, multiple varieties, small batches and low cost, and whether it can update products quickly is the key to an enterprise's invincible position in market competition. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of th...
