Embodiment 1

[0059] This embodiment provides a welding process for a central pillar reinforcement plate, the structure of which is shown in the figure.

[0060] The welding process of the center pillar reinforcement plate,

[0061] S1: Preheating, respectively put the center column reinforcement plate and the weldment to be welded into the heating chamber for a certain period of time, so that the temperature of the center column reinforcement plate and the weldment to be welded can be increased;

[0062] S2: The fixture is fixed, and the preheated center column reinforcement plate and the weldment to be welded are fixed by the welding fixture, so that the weldment to be welded is positioned at the position to be welded;

[0063] S3: combined welding,

[0064] S3': Simultaneous partial welding of the first weldment, the fourth weldment and the third weldment;

[0065] S3″: Weld the remaining parts that need to be welded on the first weldment, the second weldment and the third weldment;

[...

Embodiment 2

[0093] A welding process for a central pillar reinforcement plate, which differs from Embodiment 1 in that:

[0094] S3′: When performing local welding on the first weldment, the edge close to the right side of the gentle section on the first weldment is welded, and the brazing welding method is adopted;

[0095] Fix the second weldment by spot welding;

[0096] When performing partial welding on the third weldment, the edge close to the right side of the gentle section on the third weldment is welded, and the spot welding method is adopted;

[0097] S3″: Weld the edge of the first weldment close to the left side of the gentle section by spot welding;

[0098] The fourth weldment is welded and fixed by fiber welding;

[0099] For the third weldment close to the left side of the gentle section, spot welding is adopted.

Embodiment 3

[0101] A welding process for the reinforcement plate of the central pillar frame, the difference from Example 1 is: S1: preheating, respectively put the reinforcement plate of the central pillar and the weldment to be welded into the heating chamber for a certain period of time, so that the reinforcement plate of the central pillar and the The temperature of the weldment to be welded is increased. The specific operation method is:

[0102] F1: First put the center column reinforcement plate and the weldment to be welded into the heating chamber, keep the temperature in the heating chamber at 300°C, and place it for no less than 2 hours;

[0103] F2: Take out the center pillar reinforcement plate and install it on the welding fixture;

[0104] F3: Use a hot gun to blow air on the central column reinforcement plate, and reciprocate the air along the length of the central column reinforcement plate. After blowing the side with the groove, blow the other side of the central colum...

Abstract

The invention discloses a welding technology of a center pillar reinforcing plate and relates to the technical field of automobile part welding. The welding technology of the center pillar reinforcingplate comprises the following steps: S1, carrying out preheating; S2, carrying out fixing through fixture; S3, carrying out combination welding; S3', simultaneously carrying out partial welding on afirst welding component, a fourth welding component and a third welding component; S3'', carrying out welding on the other parts needing to be welded of the first welding component, a second welding component and the third welding component; S4, carrying out heat treatment; S5, carrying out cooling; S6, carrying out washing; S7, carrying out detection and patch welding; and S8, spraying and coating protective layers. According to the scheme, different welding components to be welded are simultaneously welded, and the influence of heat conduction among the welding components during the weldingof the welding components to be welded is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts welding, in particular to a welding process for a center pillar reinforcement plate. Background technique [0002] The center pillar reinforcement is a sheet metal part that is part of the car. Such as figure 1 As shown, the central pillar reinforcement plate 1 is made of a thin steel plate through blanking to obtain the basic outline, and then it is stamped several times to form a figure 1 the shape shown. The central pillar reinforcement panel 1 is sequentially composed of a gentle section 13 and an inclined section 12 along the length direction from left to right. An obtuse angle is formed between the inclined section 12 and the gentle section 13 . [0003] The left and right ends of the center pillar reinforcement plate 1 in the length direction are the tail end 14 and the head end 11 respectively, and correspond to the gentle section 13 and the inclined section 12 respectively. [000...
