Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to a straightening device for stainless steel pipe processing. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, mainly used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. During the manufacturing process of stainless steel pipe, due to factors such as mold wear or improper adjustment, uneven heating and cooling during rolling, cold drawing, and heat treatment, the pipe often undergoes bending deformation and needs to be straightened.

[0003] A Chinese utility model patent (Publication No.: 202420551620.3) discloses a stainless steel pipe straightening device, belonging to the field of steel pipe processing technology. It includes an operating table and a processing frame. One side of the operating table is equipped with a dual-axis motor, a belt, and two pulleys. One end of the dual-axis motor is equipped with a rotating shaft and a cam. The operating table is connected to a lower straightening component, a water tank, and a fixed frame. The water tank is connected to a water spray pipe and a piston pressurizing component. The fixed frame contains cooling fan blades and a rotating rod, with the rotating rod connected to a pulley. The processing frame contains a support plate, an upper straightening component, a limiting rod, and a buffer spring. The beneficial effects of this utility model are: the dual-axis motor, two pulleys, the pulleys, and the rotating rod drive the cooling fan blades to rotate; simultaneously, the cam and piston pressurizing component spray coolant through the water spray pipe, further enhancing the cooling effect in conjunction with the cooling fan blades. This prevents the formation of regular undulating small waves on the surface of the steel pipe due to excessively high temperatures during straightening, thus ensuring the flatness and quality of the pipe material.

[0004] However, in implementing the relevant technology, the above-mentioned stainless steel pipe straightening device has the following problems: In the process of straightening the stainless steel pipe in the above technical solution, the stainless steel pipe is cooled by coolant, and coolant residue will remain on the surface of the stainless steel pipe after straightening, which is inconvenient to clean. Therefore, a straightening device for stainless steel pipe processing is proposed. Utility Model Content

[0028] Lifting component 3 is installed through the top of support frame 1, and upper straightening component 4 is rotatably connected to both sides of the inner wall of lifting component 3.

[0031] The lifting assembly 3 adjusts the appropriate distance between the upper straightener 4 and the lower straightener 2. One end of the stainless steel tube is placed between the upper straightener 4 and the lower straightener 2, and straightening is performed by the upper straightener 4 and the lower straightener 2. The cooling assembly 9 sprays coolant onto the surface of the stainless steel tube to cool it down. When the stainless steel tube moves into the cleaning cover 6, the rubber sheet 7 scrapes off the coolant on the surface of the stainless steel tube. The drying assembly 8 dries the surface of the stainless steel tube. The upper straightener 4 and the lower straightener 2 are existing mature technologies and will not be described in detail.

[0032] Specifically, the lifting assembly 3 includes a cylinder 31 and a U-shaped plate 32. The cylinder 31 is located at the top of the support frame 1. The output end of the cylinder 31 passes through the support frame 1 and is fixedly connected to the U-shaped plate 32. The upper straightening members 4 are rotatably connected to both sides of the inner wall of the U-shaped plate 32.

[0033] The output end of cylinder 31 drives U-shaped plate 32 to move downward, adjusting the appropriate distance between upper straightener 4 and lower straightener 2.

[0034] Specifically, the drying assembly 8 includes a blower 81, a heating tube 82, an electric heating wire 83, and an annular plate 84. The blower 81 and the annular plate 84 are located on one side of the support plate 5. The output end of the blower 81 is fixedly connected to the heating tube 82. The electric heating wire 83 is located on the inner wall of the heating tube 82. One end of the heating tube 82 is connected to the annular plate 84.

[0035] The blower 81 blows air into the heating tube 82, the electric heating wire 83 heats the air, and the hot air enters the annular plate 84 and is blown out to dry the surface of the stainless steel tube.

[0036] Specifically, the cooling assembly 9 includes a housing 91, a pump body 92, and a nozzle 93. The housing 91 is located at the bottom of the support frame 1, the pump body 92 is located at the top of the housing 91, and the output end of the pump body 92 is fixedly connected to the support frame 1 and the nozzle 93 through a pipe.

[0040] Specifically, a filter plate 11 is installed on the bottom inner wall of the support frame 1;

[0041] Excess coolant sprayed from nozzle 93 flows onto the bottom inner wall of support frame 1, is filtered by filter plate 11, and then flows into housing 91 for recycling.

[0042] Specifically, an annular tube 12 is fixedly installed on one side of the support plate 5, and the annular tube 12 is threadedly connected to the cleaning cover 6.

[0043] When the rubber sheet 7 is severely worn and affects its use, rotate the cleaning cover 6 to separate it from the annular tube 12, remove the cleaning cover 6 for replacement, and replace its rubber sheet 7.

[0044] Working principle of this utility model: This utility model is a straightening device for processing stainless steel pipes. First, when in use, the output end of the cylinder 31 drives the U-shaped plate 32 to move downward. Adjust the appropriate distance between the upper straightening member 4 and the lower straightening member 2, and place one end of the stainless steel pipe between the upper straightening member 4 and the lower straightening member 2. The output end of the motor 10 drives one of the lower straightening members 2 to rotate, so that the stainless steel pipe moves through the upper straightening member 4 and the lower straightening member 2 for straightening. The pump body 92 transports the coolant in the box 91 through the pipeline to the nozzle 93 for spraying. The coolant is sprayed on the surface of the stainless steel pipe to cool it down and prevent the formation of regular undulating small waves on the surface of the stainless steel pipe.

[0045] After the stainless steel tube is moved into the annular tube 12, it passes through the cleaning cover 6. The coolant on the surface of the stainless steel tube is scraped off by the rubber sheet 7. The blower 81 blows air into the heating tube 82 and heats the air by the electric heating wire 83. Then the hot air enters the annular plate 84 and blows out to dry the surface of the stainless steel tube.
