Description

A continuous feeding device for seamless tubes Technical Field

[0001] This utility model relates to the field of seamless tube processing technology, specifically to a continuous feeding device for seamless tubes. Background Technology

[0002] Seamless steel pipe is a type of steel pipe with a hollow cross-section and no seams on its surface. It is usually made by piercing round steel bars and then processing them through processes such as hot rolling, cold rolling, or cold drawing. Seamless steel pipe has uniform wall thickness and good mechanical properties, and can withstand high pressure and impact. In the industrial field, it is widely used in pipeline systems for transporting fluids (such as oil, natural gas, water, etc.).

[0003] During the feeding process of seamless tubes, different production lines are used for tubes of different diameters. However, seamless tubes are basically produced from tube rolling machines. They need to be manually sorted and transferred to the corresponding production lines, or collected in batches and transferred in bulk. The efficiency is relatively low. Therefore, this utility model proposes a new solution to this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous feeding device for seamless pipes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous feeding device for seamless tubes, comprising:

[0006] Support frame, crossbeam frame, limiting components, and transfer mechanism;

[0007] The crossbeam is fixed to the top of the support frame, forming a gantry structure with the support frame;

[0008] The limiting components are installed at both ends of the top of the gantry structure. During the seamless tube feeding process, the limiting components limit the conveying position of the seamless tube. A lifting component is set between the two limiting components, and the seamless tube is placed at the transfer mechanism through the lifting component.

[0009] Further, the limiting member includes two side plates, which are connected across the crossbeam frame. Each limiting member has a stop plate fixed to the top of both side plates. The stop plate is horizontally positioned, and an adjustment plate is provided on the top of the stop plate. The adjustment plate has a straight groove that is perpendicular to the crossbeam frame. A screw is fixed on the stop plate, which passes through the straight groove and is screwed with a tightening handle.

[0010] Further, a channel for the seamless tube to move is formed between the two side plates. Each side plate is equipped with a slide rail on the side away from the channel. A bearing seat is slidably installed at the slide rail, and a roller is rotatably installed between two adjacent bearing seats.

[0011] Furthermore, multiple rollers are rotatably mounted between the two limiting members, and these rollers are rotatably mounted on the connected side plates.

[0012] Further, the lifting component includes a limiting plate fixed to the connected side plate. A vertically opened groove is provided in the middle of the limiting plate. A lifting rod is slidably installed in the groove. The top of the lifting rod is inclined. A hydraulic cylinder is provided on the side away from the lifting rod. The extension end of the hydraulic cylinder is fixed to the bottom of the lifting rod.

[0013] Further, the transfer mechanism includes several linear slides fixed to the bottom of the crossbeam frame. The linear slides are perpendicular to the crossbeam frame, and a receiving frame that slides along the linear slide is provided on the top of each linear slide.

[0014] Further, the receiving frame includes an inverted box that slides on top of a linear slide, with rollers rotatably mounted between the two sides of the inverted box.

[0015] Further, a first guard is fixed to one side of the top of the C-shaped box. The first guard is inclined and its height is at least higher than the top surface of the crossbeam. A second guard is fixed to the other side of the top of the C-shaped box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This seamless tube continuous feeding device, through the setting of limiting components and transfer mechanisms, can feed seamless tubes of different diameters with good feeding continuity. Furthermore, the linear slide and receiving frame in the transfer mechanism can stably receive and transfer seamless tubes.

[0025] 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.

[0026] As shown in Figure 1, this utility model provides a technical solution: a continuous feeding device for seamless tubes, including a support 1, a crossbeam 2, a limiting member 3, and a transfer mechanism. The crossbeam 2 is fixed to the top of the support 1 and forms a gantry structure with the support 1. The limiting member 3 is installed at both ends of the top of the gantry structure. During the feeding process of the seamless tube, the limiting member 3 limits the conveying position of the seamless tube. A lifting member is provided between the two limiting members 3, and the seamless tube is placed at the transfer mechanism through the lifting member.

[0027] As shown in Figures 2 and 3, to ensure the smooth implementation of this embodiment, it is necessary to understand that the limiting member 3 includes two side plates 301. The two side plates 301 of the limiting member 3 are connected after passing over the crossbeam frame 2. Each of the two side plates 301 of the limiting member 3 has a stop plate 302 fixed to its top. The stop plate 302 is horizontally set. An adjustment plate 303 is set on the top of the stop plate 302. The adjustment plate 303 has a straight groove 304, which is perpendicular to the crossbeam frame 2. A screw 308 is fixed on the stop plate 302. The screw 308 passes through the straight groove 304 and is screwed into place. There is a tightening handle 305, and a channel for the seamless tube to move is formed between the two side plates 301. Each side plate 301 is provided with a slide rail 306 on the side away from the channel. A bearing seat 307 is slidably installed on the slide rail 306. A roller 4 is rotatably installed between two adjacent bearing seats 307. The side plates 301 of the two limiting members 3 form the two side boundaries of the channel, which play a preliminary role in constraining the movement direction of the seamless tube. At the same time, the bearing seat 307 is slidably installed on the slide rail 306 on the side plate 301 away from the channel. That is to say, the feeding end of the device can be adjusted to a certain extent to facilitate feeding.

[0028] As shown in Figure 1, to ensure the smooth implementation of this embodiment, it is necessary to understand that multiple rollers 4 are rotatably installed between the two limiting members 3, and the rollers 4 are rotatably installed at the connected side plate 301.

[0029] As shown in Figure 1, to ensure the smooth implementation of this embodiment, it is necessary to understand that the lifting component includes a limiting plate 5 fixed to the connected side plate 301. A vertically formed groove is provided in the middle of the limiting plate 5, and a lifting rod 6 is slidably installed in the groove. The top of the lifting rod 6 is inclined, and a hydraulic cylinder is provided on the side opposite to the lifting rod 6. The extension end of the hydraulic cylinder is fixed to the bottom of the lifting rod 6. When the hydraulic cylinder operates, its extension end drives the lifting rod 6 to slide within the groove. When the lifting rod 6 rises, its inclined top can lift the seamless tube from the conveying channel, causing the seamless tube to leave its original conveying position and transfer it to the transfer mechanism.

[0030] As shown in Figures 1 and 2, to ensure the smooth implementation of this embodiment, it is necessary to understand that the transfer mechanism includes several linear slides 7 fixed to the bottom of the crossbeam frame 2. The linear slides 7 are perpendicular to the crossbeam frame 2. Each linear slide 7 has a receiving frame 8 that slides along it. The receiving frame 8 includes a U-shaped box 801 that slides on the top of the linear slide 7. Rollers 9 are rotatably mounted between the two sides of the U-shaped box 801. When the picking component places the seamless tube at the transfer mechanism, the receiving frame 8 moves to the appropriate position under the drive of the linear slides 7. The rollers 9 rotatably mounted between the two sides of the U-shaped box 801 of the receiving frame 8 can carry the seamless tube, and due to their rotatable nature, they can selectively transfer the seamless tube to the next production line as needed.

[0031] As shown in Figure 4, to ensure the smooth implementation of this embodiment, it is necessary to understand that a first baffle 802 is fixed on one side of the top of the C-shaped box 801. The first baffle 802 is inclined and its height is at least higher than the top surface height of the crossbeam frame 2. A second baffle 803 is fixed on the other side of the top of the C-shaped box 801. The baffles can prevent the seamless tube from detaching from the C-shaped box 801 during the transfer to the patent agency and can limit the dynamic process of the seamless tube transfer.

[0032] As shown in Figure 5, to ensure the smooth implementation of this embodiment, it is necessary to understand that a support arm 10 is fixed on the side of one of the C-shaped boxes 801 facing the crossbeam frame 2, and a connecting plate 11 is fixed at the end of the support arm 10. A rotating block 12 is rotatably installed on one side of the connecting plate 11, and a pressure shaft 13 is rotatably installed on one side of the rotating block 12. A drive source 14 is provided on the other side of the connecting plate 11 to control the rotation of the rotating block 12. When the seamless tube is transferred to the next production line, the drive source 14 works to drive the rotating block 12 to rotate, thereby causing the pressure shaft 13 to rotate and limit the seamless tube, preventing it from lateral displacement during subsequent operations.

[0033] 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.
