Description

Technical Field

[0001] The invention relates to the technical field of welding processing, in particular to welding equipment for processing a frame of a large hydraulic press. Background Art

[0002] Due to local heating during the welding process of the large hydraulic press frame, the temperature distribution of the components is uneven, resulting in large differences in expansion and contraction deformation at various locations; the forms of the welding seams at various locations are different; the metal heat dissipation conditions during welding are different, resulting in different shrinkage amounts when the molten metal solidifies, forming welding stress. The welding residual stress has 6 effects on the weldment: corrosion resistance, dimensional stability, machining accuracy, stability of pressurized weldments, stiffness, and strength; since most frame weldments are relatively regular; the existing technology mostly uses overall heat treatment to eliminate stress during stress elimination. During overall heat treatment, the entire weldment needs to be processed before stress elimination treatment. This method is complicated to operate, and as the number of welds increases, the internal stress increases, which can easily cause deformation of the weldment. The overall heat treatment cost is high, and it is not suitable for stress elimination of large frames. In addition, the existing welding equipment cannot automatically unload and requires manual assistance, and the welding efficiency is low.

[0031] The present invention discloses a welding device for processing a large hydraulic press frame, and its working principle is as follows: turning on the welding transfer motor 107 drives the welding fixed block 103 and then drives the welding transfer plate 101 to slide on the welding sliding column 105, and the welding sliding column 105 slides on the welding fixed column 106, so that the welding transfer plate 101 transfers the weldment on the welding blanking plate 111 to the welding fixed plate 112, and turning on the welding motor 108 drives the welding screw 109 and then moves the welding head 110 to realize welding of the weldment; after the welding is completed, turning on the stress relief motor to drive the elimination rotating ring 217 to rotate, and the elimination rotating ring 217 rotates to eliminate the swing connecting rod 209 and the large fixed elimination rod.
