Description

Technical Field

[0001] This utility model relates to the field of straightening machine technology, and more specifically, to a feeding device for straightening steel pipes. Background Technology

[0002] A steel pipe straightening machine is a device used to process steel pipes and metal tubing, aiming to eliminate bends, twists, and deformations in the pipes to achieve a more precise diameter and shape. Existing straightening machines, due to the inherent bending and deformation of the steel pipes before straightening, typically use a feeding rack for loading. By placing the steel pipes on the feeding rack and utilizing its tilt angle, the pipes are forced onto the conveyor rollers for straightening.

[0003] A search revealed a steel pipe straightening machine in the prior art, with patent publication number CN221848458U. The specification describes a machine frame equipped with a guide plate, a straightening machine body located at the discharge end of the guide plate, and a feeding rack located on one side of the guide plate. Steel pipes are placed on the feeding rack. The machine frame also includes a feeding assembly and a positioning assembly. The feeding assembly includes a driving component and a gripping component and a pushing component that are driven by the driving component. The gripping component is located between the feeding rack and the guide plate.

[0004] However, in actual use, the feeding rack is usually fixed to the machine body. Since the feeding rack is designed to be inclined, the steel pipes on the feeding rack are mostly in a close-fitting state. As a result, during feeding, the friction between multiple steel pipes causes the steel pipes to get stuck during the gripping and pushing process, which affects the accuracy of feeding and thus the straightening quality. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a feeding device for steel pipe straightening, which solves the problem that in the prior art, multiple steel pipes are attached to each other, resulting in large friction between them, which causes the steel pipes to jam during feeding, thus affecting the feeding accuracy and the straightening quality.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a feeding device for straightening steel pipes, comprising a machine body, two feeding racks fixedly connected to the right side of the machine body, a sliding groove provided inside the feeding rack, a plurality of slots provided inside the sliding groove, a slider slidably connected inside the feeding rack, a locking block engaged inside the slot, the locking block slidably connected inside the slider, and a stop block slidably connected to the upper side inside the slider, and the stop block slidably connected inside the sliding groove.

[0007] The slider has a placement groove on its upper inner side, and an electric telescopic rod is fixedly connected inside the placement groove. The output end of the electric telescopic rod is fixedly connected to the lower inner wall of the block.

[0008] The slider has mounting slots on both the front and rear sides. The end of the block away from the slot is fixedly connected to a mounting piece, and the other end of the mounting piece is fixedly connected to a pull rope. An elastic element is sleeved on the outside of the pull rope.

[0009] The slider has a movable block fixedly connected to its bottom end. The movable block has a limit groove inside. A pull tab is slidably connected inside the limit groove. A connecting block is fixedly connected to the bottom end of the pull tab. A handle is fixedly connected to the bottom end of the connecting block.

[0010] The stop block is slidably connected inside the placement groove, and a placement block is fixedly connected to the bottom end of the stop block. The placement block is slidably connected inside the placement groove.

[0011] The mounting plate is slidably connected inside the mounting groove, and one end of the pull rope is slidably connected inside the mounting groove.

[0012] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the inner wall of the mounting piece.

[0013] The end of the pull rope away from the mounting plate is fixedly connected to the pull plate and slidably connected inside the limiting groove, and the connecting block is slidably connected inside the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above scheme, by using blocks to separate the steel pipes, only one steel pipe can be inserted at a time. The blocks can be adjusted to accommodate steel pipes of different sizes, thus making the feeding rack more flexible and improving the economic efficiency of the device while ensuring feeding accuracy.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a feeding device for straightening steel pipes, including a body 1. Two feeding racks 2 are fixedly connected to the right side of the body 1. The feeding racks 2 have a sliding groove 3 inside, and multiple slots 4 inside the sliding groove 3. A slider 5 is slidably connected inside the feeding racks 2, and the feeding racks 2 limit the slider 5 so that the slider 5 will not deviate when sliding. A locking block 6 is locked inside the slots 4, and the locking block 6 is slidably connected inside the slider 5. The locking block 6 is used to limit the slider 5 so that the locking block 6 will not deviate after moving to a designated position. A stop block 8 is slidably connected to the upper side inside the slider 5, and the stop block 8 is slidably connected inside the sliding groove 3. The slider 5 provides movement space for the stop block 8, and the sliding groove 3 limits the stop block 8 so that the stop block 8 can move with the slider 5. The stop block 8 is used to separate the steel pipes.

[0025] When steel pipes need to be separated, by sliding the locking block 6 into the interior of the slider 5, the locking block 6 is separated from the interior of the locking groove 4, so that the locking block 6 no longer limits the slider 5. At this time, by moving the slider 5, the slider 5 can pull the stop block 8 to the designated position, and then move the stop block 8 upward, so that the stop block 8 can slide between the two steel pipes, thereby separating the steel pipes.

[0026] Example 2: Based on Example 1, in order to facilitate the movement of the stop block 8, a placement groove 9 is provided on the upper side of the inner side of the slider 5. The stop block 8 is slidably connected to the inside of the placement groove 9. The placement groove 9 limits the movement of the stop block 8, allowing the stop block 8 to slide smoothly. An electric telescopic rod 11 is fixedly connected inside the placement groove 9. The output end of the electric telescopic rod 11 is fixedly connected to the lower side of the inner wall of the stop block 8. The electric telescopic rod 11 is used to push the stop block 8 to move. A placement block 10 is fixedly connected to the bottom end of the stop block 8. The placement block 10 is slidably connected inside the placement groove 9. The placement groove 9 limits the movement of the placement block 10, preventing the placement block 10 from shifting during sliding.

[0027] When it is necessary to move the stop 8, the electric telescopic rod 11 is activated, which pushes the stop 8 upward, allowing the stop 8 to disengage from the inside of the placement groove 9 and slide inside the sliding groove 3, thereby allowing the stop 8 to separate the steel pipe.

[0028] Example 3: Based on Example 2, in order to facilitate the pulling of the locking block 6, mounting grooves 7 are provided on both the front and rear sides of the slider 5. The end of the locking block 6 away from the locking groove 4 is fixedly connected to the mounting piece 12. The mounting piece 12 is slidably connected inside the mounting groove 7. The mounting groove 7 limits the mounting piece 12, allowing it to slide smoothly. The other end of the mounting piece 12 is fixedly connected to the pull rope 14. One end of the pull rope 14 is slidably connected inside the mounting groove 7. The mounting groove 7 limits the pull rope 14, preventing it from shifting when moving. An elastic element 13 is sleeved on the outside of the pull rope 14. One end of the elastic element 13 is fixedly connected to the inner wall of the mounting groove 7, and the other end is fixedly connected to the inner wall of the mounting piece 12.

[0029] When the locking block 6 needs to be pulled, pulling one end of the pull rope 14 downwards causes the other end of the pull rope 14 to pull the mounting plate 12 inwards. This causes the mounting plate 12 to compress the elastic element 13 and deform, thereby disengaging the locking block 6 from the inside of the slot 4. Conversely, releasing the pull rope 14 allows the elastic element 13 to reset, which in turn pushes the mounting plate 12 outwards, causing the mounting plate 12 to engage the locking block 6 with the inside of the slot 4.

[0030] Example 4: Based on Example 3, in order to facilitate the pulling of the pull rope 14, a moving block 19 is fixedly connected to the bottom end of the slider 5. A limiting groove 16 is opened inside the moving block 19. A pull piece 15 is slidably connected inside the limiting groove 16. The limiting groove 16 limits the pull piece 15 so that the pull piece 15 will not deviate when sliding. The end of the pull rope 14 away from the mounting plate 12 is fixedly connected to the pull piece 15 and slidably connected inside the limiting groove 16. The pull piece 15 is used to pull the pull rope 14 to move. A connecting block 17 is fixedly connected to the bottom end of the pull piece 15. The connecting block 17 is slidably connected inside the limiting groove 16. The limiting groove 16 limits the connecting block 17 so that the connecting block 17 will not deviate when sliding. A handle 18 is fixedly connected to the bottom end of the connecting block 17. The handle 18 is connected to two connecting blocks 17 so that the handle 18 can pull the two connecting blocks 17 to move simultaneously.

[0031] When the pull rope 14 needs to be pulled, the handle 18 is pulled downward, which in turn moves the connecting block 17 downward, thereby moving the limiting groove 16 downward, and the pull piece 15 pulls the pull rope 14 downward.

[0032] The working process of this utility model is as follows:

[0033] When the stop block 8 is needed to separate the steel pipes, pulling the handle 18 downwards causes the connecting block 17 to move downwards, which in turn causes the limiting groove 16 to move downwards. This causes the pull plate 15 to pull the pull rope 14 downwards, and the other end of the pull rope 14 to pull the mounting plate 12 inwards. This causes the mounting plate 12 to compress the elastic element 13, causing it to deform and simultaneously disengaging the locking block 6 from the inside of the locking groove 4. At this time, pulling the handle 18 to the left and right causes the handle 18 to move the moving block 19 to the left and right through the connecting block 17. This causes the moving block 19 to move the slider 5 to the left and right. When the slider 5... After moving to the desired position, releasing the handle 18 allows the elastic element 13 to reset, which in turn pushes the mounting plate 12 outward, causing the mounting plate 12 to push the locking block 6 into the slot 4. Simultaneously, the electric telescopic rod 11 is activated, pushing the stop block 8 upward. This allows the stop block 8 to disengage from the placement slot 9 and slide within the slide groove 3, thus separating the steel pipes. This separation allows for the separation of steel pipes of different sizes, resulting in greater flexibility in the use of the feeding rack 2. Furthermore, while ensuring feeding accuracy, this improves the economic efficiency of the device.
