The invention discloses a vibratory stress relief device for an autoclave body, and relates to the technical field of machining equipment manufacturing. The vibratory stress relief device comprises a vibration exciter, wherein the lower end of the vibration exciter is provided with two lug plates extending sideways; each of the two lug plates of the vibration exciter is provided with an arc-shaped clamp body; the upper end of the clamp body is provided with a screw rod through a thread; and an upper backing plate and a lower backing plate are arranged between the bottom surface where the lug plates are arranged and the clamping surface of the clamp bodies. Compared with the prior art, the invention can solve the problems of high investment of stress relief equipment, high stress relief cost and difficulty in performing thermal stress relief treatment on equipment installation site in the existing autoclave body thermal stress relief; the thermal stress relief cost of the autoclave body is reduced by 98%, and the investment of the stress relief equipment is lowered by 80%; and two-year follow-up inspection shows that none of 100 autoclave bodies subjected to vibratory stress relief treatment has quality problems of deformation and cracking.
Description
technical field [0001] The invention relates to the technical field of mechanical processing equipment manufacturing, in particular to a device for performing vibration aging treatment on an autoclave body. Background technique [0002] The autoclave is a large steel horizontal pressure vessel equipment used for autoclaving curing of new lightweight wall materials, concrete pipe piles and other construction products. The autoclave includes a kettle body and a kettle cover connected at both ends of the kettle body. The kettle body is composed of a cylinder body and a toothed circular flange welded at both ends of the cylinder body. seat. The autoclave is subjected to alternating stress during use, and the superposition of these stresses and the welding residual stress of the kettle body will produce the following defects: the weld between the cylinder and the round flange, the weld between the cylinder and the support Cracks and elliptical deformation of the round flange. ...
