Description

Technical Field

[0001] The invention relates to the technical field of metal pipelines, in particular to a metal pipeline orifice corrector. Background Art

[0002] During transportation and storage, metal pipes are often squeezed out of roundness, which affects the subsequent installation and use of the pipes. People usually need to install the corrector components in the appropriate position to correct the pipe mouth of the metal pipe, which easily leads to low correction efficiency. Therefore, it is necessary to design a corrector.

[0003] Patent application number CN217315229U discloses a metal pipe nozzle correction device, which fixes the U-shaped clamp to the recess of the metal pipe nozzle by lifting and tightening the column. During correction, according to the principle of action and reaction force, the push rod pushes the protrusion downward while the U-shaped clamp pulls the recess upward to achieve synchronous correction of the protrusion and the recess. The corrector corrects the pipe nozzle by installing the push rod on a suitable mounting hole. This correction method reduces the correction efficiency.

[0004] We have designed a metal pipe nozzle corrector that does not require installation, in order to overcome the problem that the existing corrector needs to adjust the installation position of the components during use, which reduces the correction efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0054] Example 1

[0055] A metal pipe nozzle corrector, now reference Figure 1 , including a supporting frame 1, an adjusting mechanism 3 and a correcting mechanism 4. The adjusting mechanism 3 is provided on the front side of the top of the supporting frame 1, a metal tube 2 is placed on the top of the supporting frame 1, and a correcting mechanism 4 is provided on the adjusting mechanism 3.

[0056] Reference Figure 1 and Figure 2 The adjusting mechanism 3 includes a support frame 31, a motor 32 and a rotating shaft 33. The support frame 31 is fixed to the front side of the top of the support frame 1 by bolts, and the motor 32 is fixed to the upper side of the support frame 31 by bolts. The output shaft of the motor 32 is rotatably connected to the support frame 31, and the rotating shaft 33 is connected to the output shaft of the motor 32 through a coupling.

[0057] Reference Figure 1 and Figure 3 The correction mechanism 4 includes a cylinder 41 and a correction plate 42. The cylinder 41 is fixed to the rear side of the rotating shaft 33 by bolts, and the correction plate 42 is connected to the telescopic rod of the cylinder 41.

[0058] When people need to correct the pipe mouth of a metal pipe, people can use this metal pipe pipe mouth corrector. First, people place the metal pipe 2 on the top of the support bracket 1 so that the deformed pipe mouth of the metal pipe 2 is located on the front side, and the deformed part of the pipe mouth of the metal pipe 2 is located on the upper side, so that the correction plate 42 is located on the inner side of the metal pipe 2. Then people start the motor 32, so that the output shaft of the motor 32 rotates to drive the rotating shaft 33 to rotate, and then the cylinder 41 and the correction plate 42 rotate. When the correction plate 42 and the deformed part of the pipe mouth are in the same vertical line, people can turn off the motor 32. Then people start the cylinder 41 and press the metal pipe 2. The telescopic rod of the cylinder 41 extends and drives the correction plate 42 to move outward. When the correction plate 42 moves outward and contacts the inner wall of the pipe mouth of the metal pipe 2, the correction plate 42 moving outward corrects the deformed part of the pipe mouth. When the correction is completed, people control the telescopic rod of the cylinder 41 to shorten, and when the correction plate 42 moves inward to the appropriate position, people close the cylinder 41, and then people continue to start the motor 32. The output shaft of the motor 32 rotates to rotate the correction plate 42. When the correction plate 42 rotates to the appropriate position, people turn off the motor 32 and start the cylinder 41, so that the correction plate 42 moves outward to correct the deformation of the pipe mouth. When the correction of the pipe mouth of the metal pipe 2 is completed, people control the telescopic rod of the cylinder 41 to shorten according to the above steps. When the correction plate 42 moves inward to the appropriate position, people close the cylinder 41, and then people remove the metal pipe 2 from the top of the support bracket 1.

[0061] Reference Figure 1 、 Figure 5 and Figure 6, also includes a balancing mechanism 6, the balancing mechanism 6 includes a first rack rack 61, a fixed rod 62, a spur gear 63, a second rack rack 64, a slide rod 65 and a return spring 66, the first rack rack 61 is welded on both sides of the left and right sides of the correction plate 42, and a fixed rod 62 is welded on the rear side of the connecting plate 52. The left and right sides of the fixed rod 62 are rotatably connected to the spur gear 63, the first rack rack 61 on the left is meshed with the spur gear 63 on the left, and the first rack rack 61 on the right is meshed with the spur gear 63 on the right, a slide rod 65 is slidably connected to the pressure plate 53, a second rack rack 64 is welded on the top of the slide rod 65, the second rack rack 64 is meshed with two spur gears 63, a return spring 66 is connected between the second rack rack 64 and the top of the pressure plate 53, and the return spring 66 is wound around the slide rod 65.

[0062] Reference Figure 1 and Figure 7 , also includes a positioning mechanism 7, the positioning mechanism 7 includes a fixing frame 71, a positioning plate 72 and a compression spring 73, the fixing frame 71 is welded to the front side of the top of the support frame 1, the left and right sides of the fixing frame 71 are slidably connected to the positioning plates 72, and compression springs 73 are connected between the two positioning plates 72 and the fixing frame 71, and the compression springs 73 are wound around the positioning plates 72.

[0063] Reference Figure 1 、 Figure 8 and Figure 9 , also includes a reinforcement mechanism 8, the reinforcement mechanism 8 includes a fixed column 81, a tension spring 82, a slide rail 83, a first wedge block 84, a second wedge block 85 and a sliding frame 86. Two fixed columns 81 are welded on the front side of the top of the support frame 1, and a slide rail 83 is slidably connected between the two fixed columns 81. The slide rail 83 is arc-shaped, and a tension spring 82 is connected between the two fixed columns 81 and the slide rail 83. The tension spring 82 is wrapped around the fixed column 81, and the outer side of the two positioning plates 72 is connected to the second wedge block 85. The first wedge block 84 is welded on the left and right sides of the inner wall of the slide rail 83. After the first wedge block 84 on the left moves, it contacts the second wedge block 85 on the left. After the first wedge block 84 on the right moves, it contacts the second wedge block 85 on the right. A sliding frame 86 is welded in the middle of the top of the second rack frame 64, and the sliding frame 86 is slidably connected to the slide rail 83.

[0064] When people place the metal tube 2 on the top of the support bracket 1, the bottom of the pressing plate 53 contacts the outer wall of the tube mouth of the metal tube 2, and the rotation of the rotating shaft 33 drives the connecting plate 52 to rotate, thereby causing the pressing plate 53 to rotate. Since the pressing plate 53 and the correction plate 42 are on the same vertical line, when the correction plate 42 moves outward to correct the deformation of the tube mouth, the pressing plate 53 and the correction plate 42 squeeze the tube mouth of the metal tube 2 at the same time, thereby achieving the squeezing effect, avoiding excessive correction, and also reducing people's manual pressing operations.

[0065] The rotation of the correction plate 42 drives the first rack rack 61 to rotate, and at the same time, the rotation of the pressure plate 53 drives the second rack rack 64 to rotate. The correction plate 42 moves outward, driving the first rack rack 61 to move outward, thereby causing the spur gear 63 to rotate, causing the second rack rack 64 to move inward, and then the slide rod 65 moves inward, causing the return spring 66 to be compressed, and then the second rack rack 64 moves inward until it contacts the pressure plate 53, thereby achieving the pressurization effect. The inward movement of the correction plate 42 drives the first rack rack 61 to move inward, thereby causing the spur gear 63 to rotate in the opposite direction, causing the second rack rack 64 to move outward away from the pressure plate 53, and then the slide rod 65 moves outward, and the return spring 66 is reset.

[0066] When people need to place the metal tube 2 on the top of the support bracket 1, people first manually move the positioning plate 72 outward, so that the compression spring 73 is stretched. After people place the metal tube 2 on the top of the support bracket 1, people can loosen the positioning plate 72, so that the compression spring 73 resets and drives the positioning plate 72 to move inward and contact the outer wall of the metal tube 2, thereby achieving a clamping effect and avoiding the metal tube 2 from easily moving during correction and affecting the correction effect. When people need to remove the metal tube 2, people move the positioning plate 72 outward according to the above steps. When the positioning plate 72 moves outward away from the metal tube 2, people can take out the metal tube 2. After taking it out, people loosen the positioning plate 72, so that the compression spring 73 resets and drives the positioning plate 72 to move inward and reset.

[0067] The movement of the positioning plate 72 drives the second wedge block 85 to move, and the rotation of the second rack frame 64 drives the sliding frame 86 to rotate. The second rack frame 64 moves inward and drives the sliding frame 86 to move inward, so that the slide rail 83 moves downward, thereby compressing the tension spring 82, causing the first wedge block 84 to move downward. When the first wedge block 84 moves downward and contacts the second wedge block 85, the first wedge block 84 squeezes the second wedge block 85, so that the positioning plate 72 clamps the metal pipe 2, thereby achieving a reinforcement effect and preventing the positioning plate 72 from moving easily during correction. The second rack frame 64 moves outward and drives the sliding frame 86 to move outward, so that the slide rail 83 moves upward, and the tension spring 82 resets, so that the first wedge block 84 moves upward away from the second wedge block 85.

[0068] Those skilled in the art can make various other corresponding changes and deformations based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present invention.
