Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary stretching mechanism for pipe traction machine, and in particular to an auxiliary stretching mechanism for pipe traction machine. Background Technology

[0002] Pipe traction machines are key equipment in hot-rolled, cold-rolled, or welded steel pipe production lines. Their core task is to precisely control the traction speed and forming rhythm of the steel pipes to ensure that the geometric dimensions, surface quality, and straightness of the pipes meet industrial standards.

[0003] Existing pipe traction machines for steel pipe production and processing can transport steel pipes at a certain speed to assist in further processing. However, the inlet of existing round steel pipe traction machines lacks components to assist in pulling or pushing the pipes. Therefore, the pipes need to be manually lifted and aligned before entering the traction machine. This not only results in low processing efficiency but also makes it easy for the pipes to collide with the components at the inlet of the traction machine, causing damage to the traction machine components. Therefore, existing traction machines for round pipe processing are inconvenient to use. To address this, we provide an auxiliary stretching mechanism for pipe traction machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing traction machines for round pipe processing, which lack auxiliary components for feeding pipes at the inlet, and to provide an auxiliary stretching mechanism for a pipe traction machine.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an auxiliary stretching mechanism for a pipe traction machine, comprising: a traction machine body, a guide mechanism provided on one side of the traction machine body, the guide mechanism including a fixed frame, the fixed frame being fixedly connected to the traction machine body, a bidirectional threaded rod sleeved inside the fixed frame, a threaded block sleeved on the outer surface of the bidirectional threaded rod, two threaded blocks being threadedly connected to the bidirectional threaded rod, a movable frame provided at one end of the threaded block, the movable frame being fixedly connected to the threaded block, a clamping rod one being fixedly connected at one end of one of the movable frames, and a clamping rod two being fixedly connected at one end of the other movable frame, the clamping rod two being sleeved inside the clamping rod one, the clamping rod two being slidably connected to the clamping rod one, an auxiliary mechanism provided on one side of the fixed frame, the auxiliary mechanism including a connecting plate, a threaded column sleeved inside the connecting plate, the threaded column being threadedly connected to the connecting plate.

[0006] In a preferred embodiment, the threaded block is fitted inside the fixed frame and is slidably connected to the fixed frame. A bearing is fitted onto the outer surface of one end of the bidirectional threaded rod. The bearing is placed inside the fixed frame and is fixedly connected to both the inner wall of the fixed frame and the outer surface of the bidirectional threaded rod. A turntable is provided at one end of the bidirectional threaded rod and is fixedly connected to the bidirectional threaded rod.

[0007] In a preferred embodiment, the connecting plate is fixedly connected to the fixing frame, a base frame is sleeved on the outer surface of one end of the threaded column, the threaded column is rotatably connected to the base frame, and a limit rod is sleeved inside the connecting plate.

[0008] In a preferred embodiment, the limiting rod is slidably connected to the connecting plate, the limiting rod is fixedly connected to the base frame, and the base frame is provided with a rotating shaft inside.

[0023] 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.

[0024] Example 1

[0025] like Figures 1-4As shown, this utility model provides a technical solution: an auxiliary stretching mechanism for a pipe traction machine, comprising: a traction machine body 1, a guide mechanism 2 provided on one side of the traction machine body 1, the guide mechanism 2 including a fixed frame 21, the fixed frame 21 being fixedly connected to the traction machine body 1, a bidirectional threaded rod 22 sleeved inside the fixed frame 21, and a threaded block 23 sleeved on the outer surface of the bidirectional threaded rod 22, the number of threaded blocks 23 being two, the threaded blocks 23 being threadedly connected to the bidirectional threaded rod 22, a movable frame 24 provided at one end of the threaded block 23, the movable frame 24 being fixedly connected to the threaded block 23, one end of one movable frame 24 being fixedly connected to a clamping rod 25, and one end of the other movable frame 24 being fixedly connected to a clamping rod 26. 26. Clamping rod 26 is sleeved inside clamping rod 25. Clamping rod 26 and clamping rod 25 are slidably connected. An auxiliary mechanism 3 is provided on one side of the fixing frame 21. The auxiliary mechanism 3 includes a connecting plate 31. A threaded post 32 is sleeved inside the connecting plate 31. The threaded post 32 is threadedly connected to the connecting plate 31. A threaded block 23 is sleeved inside the fixing frame 21. The threaded block 23 is slidably connected to the fixing frame 21. A bearing 27 is sleeved on the outer surface of one end of the bidirectional threaded rod 22. The bearing 27 is placed inside the fixing frame 21. The bearing 27 is fixedly connected to the inner wall of the fixing frame 21 and the outer surface of the bidirectional threaded rod 22. A turntable 28 is provided at one end of the bidirectional threaded rod 22. The turntable 28 is fixedly connected to the bidirectional threaded rod 22.

[0026] In this embodiment, by setting a bidirectional threaded rod 22, which can drive two threaded blocks 23, the two threaded blocks 23 can move simultaneously in opposite directions. The two threaded blocks 23 can adjust the position of the two moving frames 24, thereby changing the position of clamping rod 1 25 and clamping rod 26. This allows clamping rod 1 25 and clamping rod 26 to limit the round tube within a certain diameter range, so that the round tube can move centrally to the feed port of the traction machine body 1. This avoids collision between the round tube and the components of the traction machine body 1, and also reduces the time spent by the processing personnel in feeding the material, making the processing efficiency of the round tube higher. A threaded column 32 is set and threadedly connected to the connecting plate 31. When the threaded column 32 rotates, it can adjust the position of the base frame 33, the rotating shaft 35 and the roller tube 36, so that when the round tube slides on the roller tube 36, it can be aligned in a short time and then enter the inner side of clamping rod 1 25 and clamping rod 26.

[0027] Example 2

[0028] like Figures 1-4As shown, the connecting plate 31 is fixedly connected to the fixed frame 21. A base frame 33 is sleeved on the outer surface of one end of the threaded column 32. The threaded column 32 is rotatably connected to the base frame 33. A limit rod 34 is sleeved inside the connecting plate 31. The limit rod 34 is slidably connected to the connecting plate 31. The limit rod 34 is fixedly connected to the base frame 33. A rotating shaft 35 is provided inside the base frame 33. The rotating shaft 35 is fixedly connected to the base frame 33. A roller tube 36 is sleeved on the outer surface of the rotating shaft 35. The roller tube 36 is rotatably connected to the rotating shaft 35. A rotating plate 37 is provided at one end of the threaded column 32 inside the base frame 33. The rotating plate 37 is fixedly connected to the threaded column 32. The rotating plate 37 is rotatably connected to the base frame 33. A handle 38 is provided at one end of the threaded column 32. The handle 38 is fixedly connected to the threaded column 32.

[0029] In this embodiment, a rotating shaft 35 and a roller tube 36 are provided simultaneously, and the roller tube 36 can rotate around the rotating shaft 35. As a result, the frictional resistance experienced by the round tube when it moves on the roller tube 36 is smaller, which reduces the physical effort required by the operator to move the round tube. A limiting rod 34 is provided, and the limiting rod 34 can slide within the connecting plate 31, so that the base frame 33 will not rotate or move when the height is adjusted.

[0030] Working principle:

[0031] like Figures 1-4 As shown, in use, the positions of clamping rod 1 25 and clamping rod 26 can be adjusted according to the diameter of the round tube. Then, the turntable 28 is rotated, driving the bidirectional threaded rod 22 to rotate. With the cooperation of the bearing 27, the bidirectional threaded rod 22 drives the two threaded blocks 23. The two threaded blocks 23 then drive the two moving frames 24 to move simultaneously in opposite directions, thus changing the usage state of clamping rod 1 25 and clamping rod 26 until the round tube can slide precisely between clamping rod 1 25 and clamping rod 26. This allows the round tube to accurately enter the traction machine body 1. Then, the auxiliary mechanism 3 is adjusted so that the roller tube 36 contacts the bottom of the round tube. The handle 38 is rotated first, using the turntable... 28 drives the threaded column 32 to rotate, and the threaded column 32 can rotate and move with the cooperation of the connecting plate 31. At the same time, the threaded column 32 can drive the rotating plate 37 to rotate inside the connecting plate 31, so that the base frame 33 can be adjusted in height under the guidance of the limit rod 34. When the roller tube 36 contacts the bottom of the round tube, the throttle 38 stops rotating. At this time, the round tube can be easily pushed into the interior of the traction machine body 1, and the roller tube 36 can rotate around the rotating shaft 35. If a new round tube is replaced and enters the interior of the traction machine body 1, the round tube will be easily moved to the clamping rod 25 and clamping rod 26 under the conveying of the auxiliary mechanism 3. After a short alignment, the round tube will enter the interior of the traction machine body 1 with the assistance of clamping rod 25 and clamping rod 26.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
