Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel stress relief, and particularly relates to a continuous stress relief production device for stainless steel production. Background Art

[0002] According to the definition in GB / T20878-2007, stainless steel is a steel with the main characteristics of being stainless and corrosion-resistant, with a chromium content of at least 10.5% and a maximum carbon content of no more than 1.2%. Stainless steel is the abbreviation of stainless acid-resistant steel. Steels that are resistant to weak corrosive media such as air, steam, and water or have stainless properties are called stainless steel; while steels that are resistant to chemical corrosive media are called acid-resistant steel. Stainless steel is often classified by its microstructure into: martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel, and precipitation-hardening stainless steel, etc. During the production and processing of stainless steel pipes, stress will be generated, and the stainless steel pipes need to be heated by a heating furnace to eliminate the stress of the stainless steel pipes.

[0003] For example, the patent application number CN217398943U discloses a continuous stress relief production device for stainless steel production. This continuous stress relief production device for stainless steel production includes a heating furnace. Installation grooves are provided on both the front and back of the heating furnace.

A gear ring is fixedly provided on the circumferential outer wall of the heating sleeve. A plurality of heating devices are fixedly provided on the inner wall of the heating sleeve in a circumferentially symmetric structure. By driving the rotation of a rotating shaft by a motor, the rotating shaft drives a gear to rotate. When the gear rotates, it drives the heating sleeve to rotate along the inner wall of the bearing through the gear ring. When the heating sleeve rotates, it drives the plurality of heating devices inside to rotate.

[0024] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Embodiment 1:

[0025] Reference Figure 1 , Figure 2 and Figure 3 , a continuous stress-relieving production device for stainless steel production, including a heating box, a plurality of mounting plates are slidably arranged on the inner wall of the heating box, a plurality of mounting shells are arranged on one side of the mounting plate, a limiting block is slidably arranged on one side of the mounting shell, a clamping block is arranged on one side of the limiting block, a plurality of limiting rollers are rotatably arranged inside the clamping block, a transportation mechanism is arranged at the bottom of the heating box, and a positioning mechanism is arranged on the top of the transportation mechanism.

[0026] Reference Figure 2 and Figure 3 , a plurality of driving cylinders are arranged on the inner wall of the heating box, the output end of the driving cylinder is connected to one side of the mounting plate, a damper is arranged inside the mounting shell, a spring is arranged outside the damper, and one end of the damper is fixedly connected to one side of the limiting block.

[0027] In this article, the driving cylinder can adjust the distance between two mounting plates, which can be adjusted according to the diameter of the stainless steel pipe, improving the application range of the device. The damper can slow down the expansion and contraction of the spring. When the clamping device rotates with the steel pipe, vibrations will occur. The damper can prevent the spring from shortening quickly, causing the stainless steel pipe to fall off. The driving cylinder and the damper are both prior arts and will not be elaborated in this article.

[0028] Reference 2 and Figure 4 , the positioning mechanism includes a fixing plate arranged inside the heating box, a turntable is rotatably arranged inside the fixing plate, a transmission rod is rotatably arranged inside the turntable, a collision head is arranged at one end of the transmission rod, a movable block is slidably arranged on the surface of the transmission rod, a support block is arranged on one side of the movable block, a first connecting rod is rotatably arranged on one side of the collision head, a second connecting rod is rotatably arranged on the surface of the movable block, the other end of the second connecting rod is rotatably arranged with a T-shaped rod, the other end of the T-shaped rod is rotatably connected to the first connecting rod, a positioning motor is arranged outside the heating box at one end of the transmission rod, the positioning motor is in transmission connection with the transmission rod, and a telescopic rod is arranged on one side of the turntable, and the output end of the telescopic rod is fixedly connected to one side of the movable block.

[0029] In this article, when the movable block moves towards the collision head, it will lift the T-shaped rod through the second connecting rod, so that the T-shaped rod abuts against the inside of the stainless steel pipe to support the stainless steel pipe, and the positioning motor drives the transmission rod to rotate, thereby driving the stainless steel pipe to rotate. The support block is used to support the T-shaped block to prevent the T-shaped block from sinking downward. When the movable block moves, the first connecting rod drives the T-shaped block to move downward and lock. The positioning motor is a prior art and will not be elaborated in this article.

The output shaft of the driving cylinder will push the two mounting plates to move relative to each other, and the mounting plate will drive the limit block to move through the mounting shell. The limit block drives the clamping block to clamp the stainless steel pipe. Since the surface of the clamping block is provided with a rotatable limit roller, the stainless steel pipe can rotate on the surface of the clamping block, and the transportation mechanism transports the stainless steel pipe to the outside of the positioning mechanism.

[0032] The telescopic rod is controlled to extend, and the telescopic rod pushes the movable block to move along the transmission rod. The second connecting rod of the movable block is tilted and lifts the T-block upward. After the T-block is lifted upward, it drives the first connecting rod. The first connecting rod is tilted and supports the T-block, so that the T-block abuts against the inside of the stainless steel pipe. The positioning motor is started, and the output shaft of the positioning motor drives the transmission rod to rotate. The transmission rod drives the first connecting rod to rotate through the anti-collision head. The first connecting rod drives the stainless steel pipe to rotate through the T-block. At this time, the outside of the stainless steel pipe can be evenly contacted with the heat generated by the heating device, thereby cooperating with the heating device to complete the uniform heating of the stainless steel surface.
