Carrier packaging process of three-way catalytic converter and carrier pressing machine

Abstract

The invention discloses a carrier packaging process of a three-way catalytic converter and a carrier pressing machine. The process comprises the following steps of: carrier calibration, pad weighing, carrier packaging, carrier pressing, bar code scanning and detecting, cylinder reducing, gap detection and welding. The carrier pressing machine comprises a cabinet body, a fixed table, an upper centering mode and a mounting table, wherein the fixed table is arranged in the cabinet body; the upper centering mode is arranged on the fixed table; the mounting table is arranged under the fixed table and controlled by an air cylinder to lift; the mounting table is provided with a through hole; a cylindrical guide compressing mould extends downwards from the periphery of the through hole; a carriertray is arranged under the guiding compressing mould; and the carrier tray is fixed on a lead screw which is controlled by a servo motor to lift. By using the process and the structure, the inventionhas the following advantages that: the production is convenient and the produced carrier is difficult to crack; and the fixed-quantity reducing of the cylinder in the catalytic converter packaging process is solved so that the outside diameter of the catalytic converter can uniformly shrink for many times without indentation, the whole body is thin and tightened, and the pad is uniformly compressed and deformed.

Description

technical field [0001] The invention relates to the technical field of three-way catalytic converters, in particular to a three-way catalytic converter carrier packaging process and a carrier press-fitting machine. Background technique [0002] The rapid development of the automobile industry has promoted social progress and economic prosperity, but the harmful gases emitted by automobiles have brought serious pollution to the atmosphere on which human beings live. According to statistics, automobile exhaust pollution accounts for about 50% of air pollution, so the research on automobile exhaust purification has become an important aspect of environmental pollution prevention and control. The three-way catalytic converter packaging line is the production equipment of the three-way catalytic converter, which is an automobile exhaust emission treatment part. With the further improvement of the automobile industry's requirements for exhaust emissions, my country has begun to g...

Problems solved by technology

In the bundling packaging process, the roundness of the cylinder is prone to be poor, and the cylinder is prone to misalignment and straight lines; in the bundling spot welding process, the guide end of the cylinder is easy to enter the liner, causing a certain degree of damage to the liner , there is an overlap in the barrel, the gasket at the overlap is over-compressed, and the gap between the shell of the workpiece and the carrier after binding is uneven, resulting in a sharp increase in the bearing capacity of the carrier in the overlap area, and the carrier is easy to crack
