Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically a high-precision stainless steel pipe bending and forming equipment. Background Technology

[0002] Stainless steel pipes are tubular components made from stainless steel materials (such as 304, 316L, 201, etc.) through processes such as rolling, extrusion, welding, or seamless forming. With their core advantages such as corrosion resistance, high strength, easy cleaning, and long service life, they have become key materials in fields such as fluid transportation, structural support, and equipment manufacturing. Stainless steel pipe processing requires the use of equipment such as pipe bending machines.

[0003] Existing patent document with application number 202322786222.8 discloses a seamless steel pipe bending machine, including a machine base, a moving platform, and a mounting platform. The moving platform is connected to the mounting platform via a connecting block. A first guide roller group is installed on the top of the machine base, and a second guide roller group corresponding to the first guide roller group is installed on the top of the moving platform. A moving mechanism for pulling the moving platform is provided inside the machine base. A turntable is rotatably connected to the top of the mounting platform, and a rotating mechanism for driving the turntable to rotate is provided inside the mounting platform. Bending rollers are installed on the top of the turntable, and a mounting seat is provided on one side of the turntable. In this utility model, the positions of the moving platform and the mounting platform can be uniformly adjusted, which is beneficial for bending seamless steel pipes of different diameters. The seamless steel pipe can be bent from the first guide roller group and the second guide roller group. The rollers pass between the roller sets, suitable for guiding and conveying seamless steel pipes of different lengths. The bending rollers cooperate with the pressing seat to fix the seamless steel pipes and then rotate to perform bending operations on the seamless steel pipes. Although the above application has many beneficial effects, it still has the following shortcomings: The moving platform is equipped with multiple sets of guide rollers. Although it can meet the needs of steel pipe conveying, it is limited by the design of multiple sets of guide rollers. When bending steel pipes of different diameters, it is necessary to disassemble the old rollers and install the new rollers for each set of guide rollers one by one. The whole process requires repeated disassembly and assembly. Not only are the operation steps cumbersome and labor-intensive, but it also leads to a significant extension of the equipment downtime adjustment cycle, which seriously affects the continuity of bending operations and overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision stainless steel pipe bending and forming equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision stainless steel pipe bending and forming equipment, comprising a worktable, a support roller rotatably connected to one side of the worktable surface, a mounting frame fixedly connected to the worktable, a first motor fixedly mounted on one side of the mounting frame surface, a bracket fixedly connected to the output end of the first motor, and a bending roller fixedly connected to the top of the bracket.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] A high-precision stainless steel pipe bending and forming equipment includes a workbench 1, a support roller 2 rotatably connected to one side of the surface of the workbench 1, a mounting frame 3 fixedly connected to the workbench 1, a first motor 4 fixedly mounted on one side of the surface of the mounting frame 3, a bracket 5 fixedly connected to the output end of the first motor 4, and a bending roller 6 fixedly connected to the top of the bracket 5.

[0020] The workbench 1 and the mounting frame 3 are both equipped with a speed adjustment mechanism 7. The speed adjustment mechanism 7 includes a guide rail 71 and a slide groove 72. A first lead screw 73 is rotatably connected to the guide rail 71. A moving block 74 is slidably connected inside the guide rail 71. A moving column 75 is slidably connected inside the guide rail 71. A second motor 76 is fixedly installed at the top of the moving block 74. A mounting block 77 is slidably connected inside the slide groove 72 at the position corresponding to the output end of the second motor 76. A guide roller 78 is rotatably connected to the mounting block 77. Two clamping plates 79 are slidably connected to the moving column 75. A probe plate 701 is slidably connected inside each clamping plate 79. A spring 702 is fixedly connected inside each clamping plate 79 at one end corresponding to the probe plate 701. A second lead screw 703 is rotatably connected inside the moving column 75.

[0021] A track groove is provided on the workbench 1 at the position corresponding to the bending roller 6. The output shaft of the bending roller 6 is slidably connected inside the track groove. When the bending roller 6 rotates, it can slide along the track groove and cooperate with the support roller 2 to bend the steel pipe. The guide rail 71 is fixedly connected to the other side of the surface of the mounting frame 3. The slide groove 72 is opened on the workbench 1 at the position corresponding to the guide rail 71. The guide rail 71 can guide the movement of the moving column 75 and the moving block 74. The first lead screw 73 and the second lead screw 703 are both bidirectional lead screws. The first lead screw 73 is threadedly connected to the moving block 74 and the moving column 75. The second lead screw 703 is connected to the clamping plate 79 at the position inside the moving column 75. The device is equipped with a threaded connection. The first lead screw 73 facilitates the movement of the moving block 74 and the moving column 75. The second lead screw 703 facilitates the simultaneous movement of the two clamping plates 79. The output end of the second motor 76 is fixedly connected to the bottom end of the output shaft of the guide roller 78. The mounting block 77 and the moving column 75 are both slidably connected to the slide groove 72. One end of the probe plate 701 abuts against the guide roller 78. One end of the spring 702 is fixedly connected to the probe plate 701. The second motor 76 facilitates the rotation of the guide roller 78. The slide groove 72 facilitates the support and guidance for the movement of the mounting block 77. The spring 702 is in a compressed state, which facilitates the extension of the probe plate 701.

[0022] In use, the first lead screw 73 can be rotated directly through one end. The first lead screw 73 will drive the moving block 74 and the moving column 75 to move away from each other in the guide rail 71. The movement of the moving block 74 will drive the second motor 76 to move. The second motor 76 will drive the mounting block 77 and the guide roller 78 to move through the output shaft of the guide roller 78. The mounting block 77 will move in the slide groove 72, while the moving column 75 will drive the clamping plate 79 to move. When the clamping plate 79 moves, its internal spring 702 will gradually return to its original position. The returned spring 702 will drive the probe plate 701 to extend outward from the clamping plate 79. At this time, even if the guide roller 78 moves, one end of the probe plate 701 will always be in contact with the guide roller 78 under the support of the spring 702. After the distance between the moving column 75 and the guide roller 78 is adjusted, the second lead screw 703 can be rotated directly through the top end. The rotation of the second lead screw 703 will drive the two clamping plates 79 to move away from each other in the guide rail 71. Move the upper part of the steel pipe in a direction away from each other until the distance between the two clamping plates 79 is adjusted. Then place the steel pipe between the moving column 75, the guide roller 78, and the two clamping plates 79. The clamping plates 79 will provide support for the steel pipe, and the probe plate 701 will not support the weight of the steel pipe. At this time, the operator only needs to replace the support roller 2 and the bending roller 6 with appropriate ones. There is no need to replace the guide roller 78. After the support roller 2 and the bending roller 6 are replaced, start the second motor 76. The output end of the second motor 76 will drive the guide roller 78 to rotate. The guide roller 78 will rub against the outer wall of the steel pipe, causing the steel pipe to move between the support roller 2 and the bending roller 6. When the end of the steel pipe is placed between the bending roller 6 and the support roller 2, start the first motor 4. The first motor 4 will drive the bracket 5 and the bending roller 6 to rotate. The bending roller 6 will rotate around the support roller 2 as the center, thereby bending the steel pipe with the support of the support roller 2. Repeat this process. The guide roller 78 is easy to adjust, which can greatly reduce the adjustment time of the guide roller 78.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
