DETAILED DESCRIPTION
[0026] The following will be combined with the attached embodiment of the present utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0027] A stainless steel pipe straightening device comprises a frame 1, wherein a transfer mechanism 2 is arranged on the inner side of the frame 1, wherein the transfer mechanism 2 comprises two vertical frames 21 arranged on the ground, a movable frame 23 is fixedly installed between the two vertical frames 21, two connecting rods 24 are fixedly connected at the center of the bottom of the movable frame 23, a rotating wheel 27 is movably installed at the bottom end of the connecting rod 24, a rotating shaft rod 26 is penetrated through one side of the rotating wheel 27, one end of one rotating shaft rod 26 is fixedly installed on the vertical frame 21 away from the connecting rod 24, a gear 28 is fixedly installed on one end of the rotating shaft rod 26, and the two gears 28 are connected by chain transmission, a stepping motor 25 is arranged below the movable frame 23, and the output shaft of the stepping motor 25 is fixedly connected to one of the rotating shaft rods 26, and both ends of the opposite sides of the two vertical frames 21 are provided with limit assemblies 22 adapted to the movable frame 23.
[0028] The specific usage process is as follows: first, the user places the steel pipe on the two vertical frames 21, and the steel pipe must be located in the corresponding 210. It should be noted that when the movable frame 23 is not working, the steel pipe placement slot 1 29 is also aligned with the steel pipe placement slot 2 210, so the steel pipe is also located in the corresponding steel pipe placement slot 1 29. Then the user can start the stepper motor 25 to work, and the stepper motor 25 drives the corresponding rotating shaft rod 26 to rotate, and the rotating shaft rod 26 will drive the corresponding gear 28 to rotate. Driven by the chain, when the current gear 28 rotates, it will also drive the gear 28 on the other side to rotate, and then the other corresponding rotating shaft rod 26 will also rotate accordingly. At this time, the two rotating shaft rods 26 can rotate at the same time, and then the two rotating wheels 27 will also rotate at the same time. Since the rotating wheel 27 and the connecting rod 24 are connected in the form of an eccentric wheel, when the rotating wheel 27 drives the connecting rod 24 to move, it will also drive the connecting rod 24 to move along the moving track of the eccentric wheel. At the same time, the movable frame 23 connected to the connecting rod 24 is also installed to move along the same track. It should be noted that the limiting component 22 is used to limit the movable frame 23. Specifically, when the movable frame 23 moves to transfer the steel pipe, the movable frame 23 will drive the limiting slide bar 221 to slide in the inner cavity of the limiting slide groove 223, and slide in a circular track. Moreover, the diameter of the limiting slide groove 223 is the same as the distance the steel pipe is transferred, which meets the working needs of the user. In this way, the limiting component 222 and the limiting slide groove 223 can limit the movement of the movable frame 23. The movable frame 23 has the function of limiting the position, ensuring the stability of the movable frame 23 during its movement. As the movable frame 23 works along the trajectory of the eccentric wheel, that is, the movable frame 23 moves following the rotation trajectory of the rotating wheel 27, when the connecting part of the rotating wheel 27 and the connecting rod 24 moves downward, the movable frame 23 will also move downward, and then take the current position as the starting point, rotate downward for one circle, and then return to the starting point again. In this process, the movable frame 23 has moved the steel pipe to the next steel pipe placement groove 210, and since there are multiple steel pipe placement grooves 29, multiple steel pipes can be moved forward at one time. It should be noted that although multiple steel pipes can be moved forward at the same time, the moving distance of the steel pipe is still fixed, and only one steel pipe under the downward pressure straightening device 4 is moved forward at a time. And the steel pipe can only move a unit distance at a time. This unit distance is the distance between two adjacent steel pipe placement grooves 210, that is, the diameter length of the limiting slide groove 223. This is the prior art and will not be described in detail in the text. Moreover, the user can also make corresponding adjustments to the specific moving distance according to the actual working situation to meet the working needs, which provides convenience for the user's work. When a steel pipe moves to the bottom of the downward straightening device 4, the two steel pipe clamping devices 6 will start working. The two steel pipe clamping devices 6 can clamp and fix the steel pipe from both ends of the steel pipe to ensure the stability of the steel pipe being straightened. At the same time, they can also drive the steel pipe to rotate and adjust the bending position, which provides convenience for the user's work. When the downward straightening device 4 presses down and straightens the steel pipe,The steel pipe clamping device 6 will also follow the adaptive movement, and the steel pipe clamping device 6 moves on the inner side of the limit frame 5, so that the limit frame 5 can limit the movement of the steel pipe clamping device 6. At the same time, the steel pipe clamping device 6 will also compress the corresponding spring, and when the steel pipe is not pressed down, the spring will also lift the steel pipe clamping device 6 to reset, so that the steel pipe returns to its original position, so as to facilitate the next round of straightening work. Among them, the position adjustment device 3 is used to drive the entire downward pressure straightening device 4 to adjust the position horizontally, so as to meet more work requirements. This is the prior art, and it is not explained in detail in the text. The output end of the downward pressure straightening device 4 will extend and move downward, and then the output end will press on the steel pipe, and the bent part of the steel pipe will be pressed down and straightened, and then it can be used in conjunction with the work of the position adjustment device 3 to achieve the bending and straightening of the entire steel pipe, meet the work needs of users, and provide convenience for users' work.
[0029] Therefore, a continuous interval pipe transfer structural design is adopted, so that the pipe transfer work can be briefly paused according to work needs. After the pipe is straightened, the corresponding structure will move the pipe out again, and at the same time move the next pipe to the current position for straightening, to ensure that the machine has enough time to straighten the pipe, to ensure that the pipe straightening work is carried out continuously and smoothly, and to improve the quality of the pipe straightening work.
[0030] The limiting assembly 22 includes a limiting member 222 fixedly connected to the vertical frame 21 and a limiting slide rod 221 fixedly connected to the movable frame 23. A limiting slide groove 223 is provided on one side of the limiting member 222. The limiting slide rod 221 extends into the inner cavity of the limiting slide groove 223 toward one end of the limiting member 222 and slides in the inner cavity of the limiting slide groove 223.
[0031] Specifically, the setting of the limit component 22 is used to limit the movable frame 23. Specifically, when the movable frame 23 moves to transfer the steel pipe, the movable frame 23 will drive the limit slide bar 221 to slide in the inner cavity of the limit slide groove 223, and slide in a circular trajectory. Moreover, the diameter of the limit slide groove 223 is the same as the distance the steel pipe is transferred, which meets the user's work needs. In this way, the limit member 222 and the limit slide groove 223 can limit the movement of the movable frame 23 and ensure the stability of the movable frame 23 during movement.
[0032] Both sides of the top of the movable frame 23 are provided with uniformly distributed steel pipe placement grooves 29, and the top of the vertical frame 21 is provided with uniformly distributed steel pipe placement grooves 210. Steel pipes are placed inside the steel pipe placement grooves 29 and 210.
[0033] Specifically, the arrangement of the steel pipe placing groove 1 29 and the steel pipe placing groove 2 210 is such that the spacing between two adjacent steel pipe placing grooves 1 29 and steel pipe placing grooves 2 210 is the interval of one unit distance for transferring the steel pipe. In this way, when the steel pipe is transferred from the previous steel pipe placing groove 1 29 to the next steel pipe placing groove 1 29, it can be ensured that the steel pipe will not move at will, thereby ensuring the accuracy of the steel pipe straightening work and providing convenience for the user's work. The steel pipe placing groove 210 also achieves the same function.
[0034] A baffle plate 211 is disposed on the outer side of the stand 21 , and bolts evenly distributed are penetrated through one side of the baffle plate 211 . The baffle plate 211 is fixedly mounted on the stand 21 by bolts.
[0035] Specifically, the baffle 211 can block and protect the steel pipe, prevent the steel pipe from falling off the machine during transfer, ensure the smooth progress of the steel pipe straightening work, and provide convenience for the user's work.
[0036] Limiting frames 5 are fixedly installed at both ends of the inner bottom of the frame 1, and steel pipe clamping devices 6 are movably installed on the inner side of the limiting frames 5. Both steel pipe clamping devices 6 are compatible with the steel pipes. Evenly distributed springs are arranged at the bottom of the inner side of the limiting frames 5, and the top ends of the springs are fixedly connected to the steel pipe clamping devices 6, and the bottom ends of the springs are fixedly connected to the inner wall of the limiting frames 5.
[0037] Specifically, the setting of the limit frame 5, the steel pipe clamping device 6 and the spring, the two steel pipe clamping devices 6 can clamp and fix the steel pipe from both ends of the steel pipe to ensure the stability of the steel pipe being straightened, and at the same time can also drive the steel pipe to rotate and adjust the bending position, providing convenience for the user's work. When the downward straightening device 4 presses down to straighten the steel pipe, the steel pipe clamping device 6 will also follow and make adaptive activities, and the steel pipe clamping device 6 is active on the inner side of the limit frame 5, so that the limit frame 5 can limit the activity of the steel pipe clamping device 6, and at the same time, the steel pipe clamping device 6 will also compress the corresponding spring, and when the steel pipe is not pressed down, the spring will also lift and reset the steel pipe clamping device 6, so that the steel pipe returns to its original position for the next round of straightening work.
[0038] A downward pressing straightening device 4 is slidably installed on the top of the inner side of the frame 1, and the output end of the downward pressing straightening device 4 is adapted to the steel pipe. A position adjustment device 3 is fixedly installed on the top of the downward pressing straightening device 4.
[0039] Specifically, the setting of the downward pressure straightening device 4 and the position adjustment device 3, the position adjustment device 3 is used to drive the entire downward pressure straightening device 4 to move horizontally and adjust the position, so as to meet more work requirements. This is the prior art and will not be explained in detail in the text. The output end of the downward pressure straightening device 4 will extend and move downward, and then the output end will be pressed on the steel pipe to press down and straighten the bent part of the steel pipe, and then cooperate with the position adjustment device 3 to achieve the bending and straightening of the entire steel pipe, meet the user's work needs, and provide convenience for the user's work.

The essence of the utility model is to optimize the combination of existing hardware and its connection method for specific application scenarios to meet the adaptation needs in specific application scenarios and solve the problems raised in the background technology (not involving improvements to the software inside the hardware).
