Technical Field

[0001] This utility model relates to the field of seamless tube technology, specifically a stress relief device for seamless tube forming. Background Technology

[0002] Seamless pipe is a type of metal pipe, typically made of materials such as carbon steel, alloy steel, and stainless steel. Its characteristic is that there are no welds or joints in the pipe wall, thus giving it high strength and pressure resistance. Due to its seamless nature, seamless pipe is widely used in applications requiring high fluid flow and strength and pressure resistance. During the manufacturing process, internal stress may be generated in seamless pipe. To ensure the stability and performance of the pipe, stress relief treatment is usually required. This is achieved through mechanical vibration or ultrasonic treatment, which helps reduce internal stress and improve material properties.

[0003] Existing stress relief mechanisms for seamless steel pipes cannot evenly strike the pipes, resulting in poor uniformity of vibration force and affecting the stress relief effect. Therefore, we propose a stress relief device for seamless pipe forming. Utility Model Content

[0004] The purpose of this invention is to provide a stress relief device for seamless pipe forming, which has the effect of uniformly tapping and vibrating the seamless steel pipe, so as to solve the problem that the existing stress relief mechanism for seamless steel pipe cannot uniformly tap the seamless steel pipe, resulting in poor uniformity of vibration force and affecting the stress relief effect of the seamless steel pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stress relief device for seamless tube forming, comprising a stress relief box and a stress relief ring, wherein a support seat is installed at the bottom of the stress relief box near both the front and rear surfaces, a slide rod is installed at the top of the support seat, springs are installed on both sides of the outer surface of the slide rod via spring seats, a stress relief ring is installed at the end of the slide rod, a drive motor is installed at the bottom of the stress relief box, and a cam is installed on the output shaft of the drive motor at one end of the slide rod.

[0006] Preferably, a flipping motor is installed at both ends of the front surface of the elimination ring, a flipping frame is installed on the output shaft of the flipping motor, and elimination bosses are installed on the inner surfaces of both the elimination ring and the flipping frame.

[0008] Preferably, an electric telescopic device is installed inside the elimination box at the top of the support wheel, a transmission frame is installed on the output shaft of the electric telescopic device, and a transmission wheel is installed inside the transmission frame.

[0009] Preferably, the top of the noise-eliminating box is equipped with a sound-collecting cover, the top of the sound-collecting cover is equipped with a sound guide tube, the end of the sound guide tube is equipped with a silencer, and the end of the silencer is equipped with a silencer tube.

[0010] Preferably, the silencer has a silencer chamber D on the side near the sound guide tube, and a silencer chamber A is provided on the side of the silencer near the silencer chamber D through a partition. The silencer chamber A has a horizontal partition inside, and the horizontal partition is staggered.

[0011] Preferably, the silencer has a silencer chamber C located on the side of the silencer chamber closest to the silencer chamber A, and a silencer chamber B located on the side of the silencer chamber closest to the silencer chamber C. The silencer chamber B is equipped with a sound-absorbing baffle.

[0012] Preferably, the silencing chamber C is equipped with sound-absorbing cotton, and a sound guide tube is installed in the gap between the silencing chamber C and the silencing chamber A.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves the effect of uniformly tapping and vibrating seamless steel pipes by setting up a support base, slide bar, drive motor, cam and stress relief ring. This solves the problem that the existing stress relief mechanism for seamless steel pipes cannot tap the seamless steel pipes evenly, resulting in poor uniformity of vibration force and affecting the stress relief effect of the seamless steel pipes. It improves the vibration uniformity of the seamless steel pipes, thereby ensuring the stress relief effect of the seamless steel pipes.

[0015] 2. This utility model improves the stress relief mechanism's covering performance by incorporating a flipping motor, flipping frame, stress relief ring, and stress relief boss. This solves the problem that existing stress relief mechanisms, which are fixed in place, cannot be adjusted in time according to the diameter of the seamless steel pipe, thus affecting the stress relief effect of the seamless steel pipe. The improved covering effect of the stress relief mechanism ensures the stress relief effect of the seamless steel pipe.

[0016] 3. This utility model achieves the effect of eliminating stress relief noise by setting a sound guide tube and a silencer, thereby solving the problem that existing seamless steel pipes generate a lot of noise during stress relief, which cannot be silenced in time and is prone to noise pollution. This reduces the noise during stress relief and thus ensures the environmental protection effect of seamless steel pipe production. Attached Figure Description
