Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe straightening technology, specifically to an inlet guide structure for a straightening machine. Background Technology
[0002] The steel pipe straightening machine is a mechanical equipment specially used to repair bent and deformed steel pipes in building coupler-type steel pipe scaffolding. It is widely used in construction companies, rental units and scaffolding construction units. It integrates straightening, rust removal and painting functions, and can complete the surface cleaning, rust removal and painting renovation of steel pipes in one go, greatly improving work efficiency. Straightening machines generally do not have a dedicated guiding mechanism. Because the structure of bent steel pipes is relatively complex and not uniform, when straightening, the steel pipes are usually manually placed into the straightening machine. This placement method is time-consuming and has certain dangers. Utility Model Content
[0003] The technical problem this invention aims to solve is that existing straightening machines do not have a dedicated guiding mechanism. Due to the complex structure of bent steel pipes, the steel pipes are usually manually installed and inserted into the straightening machine. This method of placement is time-consuming and poses certain risks.
[0004] To solve the above problems, the technical solution adopted by this utility model is an inlet guide structure for a straightening machine, including: a conical guide cylinder, a sealing plate fixed at one end of the conical guide cylinder, a through hole in the middle of the sealing plate, an annular groove in the inner edge of the through hole, a movable plate sliding in the annular groove, a round hole in the middle of the movable plate, and a rubber sleeve on the edge of the round hole. A support frame is fixed to the outside of the tapered guide cylinder. One end of the support frame is fixed to the guide frame at the narrow end of the tapered guide cylinder. Guide rollers are symmetrically arranged inside the guide frame, and a limiting structure is provided on the outside of the guide rollers.
[0005] As a further embodiment of this invention, the diameter of the movable plate is smaller than the diameter of the annular groove, so that it can move in the annular groove and adapt to the conveying of steel pipes with different degrees of curvature.
[0006] As a further embodiment of this utility model: the limiting structure includes a connecting frame located inside the support frame, a guide roller rotatably disposed inside the connecting frame, a limiting rod fixed at one end of the connecting frame passing through the guide frame, a baffle fixed at one end of the limiting rod, and a compression spring provided on the outer side of the limiting rod between the connecting frame and the guide frame, which can cause the guide roller to be squeezed inward towards the guide frame.
[0007] As a further embodiment of this utility model: several support columns are fixed on the lower side of the support frame, and a base plate is fixed at the bottom of the support column for supporting it on the ground.
[0008] As a further embodiment of this utility model, the inner side of the rubber sleeve is coated with lubricating grease to facilitate the transport of steel.
[0009] Compared with the prior art, the advantages of this utility model are: this application adds a conical guide cylinder and a guide roller, which can support and guide irregular steel pipes without the need for manual support of the steel pipes, thereby improving safety and work efficiency.

[0015] 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.
[0016] This utility model provides a technical solution to address the existing problems mentioned in the background art.
[0017] Combined with appendix Figure 1 , 34. It can be seen that it includes: a conical guide cylinder 1, a sealing plate 2 fixed at one end of the conical guide cylinder 1, a through hole in the middle of the sealing plate 2, an annular groove 2.1 on the inner edge of the through hole, a movable plate 3 slidingly disposed in the annular groove 2.1, a round hole 3.1 in the middle of the movable plate 3, a rubber sleeve 4 fitted on the edge of the round hole 3.1, and a lubricating grease coated on the inner side of the rubber sleeve 4 to facilitate the conveying of steel. The diameter of the movable plate 3 is smaller than the diameter of the annular groove 2.1 so that it can move in the annular groove 2.1 to adapt to the conveying of steel pipes with different degrees of curvature. Combined with appendix Figure 1 , 2 It can be seen that a support frame 5 is fixed on the outside of the conical guide cylinder 1, and several support columns 11 are fixed on the lower side of the support frame 5. A base plate 12 is fixed at the bottom of the support column 11 for support on the ground. A guide frame 6 is fixed at one end of the support frame 5 at the narrow end of the conical guide cylinder 1. Guide rollers 7 are symmetrically arranged on the inner side of the guide frame 6. A limiting structure is provided on the outer side of the guide rollers 7. The limiting structure includes a connecting frame 8 located inside the support frame 5. The guide rollers 7 are rotatably arranged inside the connecting frame 8. A limiting rod 9 passing through the guide frame 6 is fixed at one end of the connecting frame 8. A baffle is fixed at one end of the limiting rod 9. A compression spring 10 is provided on the outer side of the limiting rod 9 between the connecting frame 8 and the guide frame 6, which can cause the guide rollers 7 to be squeezed inward towards the guide frame 6.
[0018] The working principle of this utility model is as follows: When straightening a steel pipe, the device is first placed next to the straightening machine, with the narrow end of the conical guide cylinder 1 aligned with the inlet of the straightening machine. Then, the steel pipe is inserted into the rubber sleeve 4, allowing it to enter the conical guide cylinder 1. One end of the steel pipe extends out from one end of the conical guide cylinder 1 and is guided by a pair of guide rollers 7. Subsequently, due to the bending of the steel pipe, the moving plate 3 moves in the annular groove 2.1 to adapt to the bending degree of the steel pipe.
[0019] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
