Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a precision steel pipe quantitative feeding device. Background Technology

[0002] In modern manufacturing, steel pipes, as an important basic material, are widely used in construction, machinery processing, automobile manufacturing, and other fields. In the steel pipe processing production process, the quantitative feeding device is a key piece of equipment to ensure production efficiency and product quality. Traditional steel pipe feeding methods mostly rely on manual handling and manual counting, which is not only inefficient but also prone to inaccurate feeding quantities due to human error, affecting the accuracy of subsequent processing. With the development of automated production technology, some enterprises have introduced mechanical feeding devices, but existing equipment generally suffers from problems such as complex structure, inconvenient adjustment, and insufficient quantitative accuracy. Especially in precision steel pipe processing, the requirements for feeding quantity, speed, and stability are even higher, making it urgent to develop new quantitative feeding devices to meet the needs of modern, high-precision production.

[0003] The existing steel pipe feeding devices mainly adopt the following technical solutions: First, gravity feeding mechanism, which uses an inclined track to make the steel pipe roll to the designated position by its own weight, and then the cylinder realizes single feeding control; second, chain feeding device, which uses chain drive to move the steel pipe, and uses photoelectric sensor to count to realize quantitative measurement; and third, vibratory disc feeding equipment, which uses vibration to make the steel pipes arranged and transported along the track.

[0004] However, existing steel pipe feeding devices generally suffer from difficulty in accurately controlling the feeding quantity, resulting in low production efficiency and insufficient processing accuracy. Traditional feeding equipment mostly adopts a single mechanical limit or simple counting method, which cannot flexibly adjust the feeding quantity according to different steel pipe specifications and production process requirements. During processing, if the single feeding quantity is too large, it will lead to a decrease in the processing accuracy of subsequent cutting and welding processes. If the quantity is insufficient, frequent machine shutdowns are required to replenish the feeding, reducing production efficiency. Therefore, a precision steel pipe quantitative feeding device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a precision steel pipe quantitative feeding device, which aims to improve the problem of low production efficiency and insufficient processing accuracy caused by the difficulty in accurately controlling the feeding quantity in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A precision steel pipe quantitative feeding device includes a support frame, a bracket fixedly connected to the top of the support frame, a support plate fixedly connected inside the support frame, a motor fixedly connected to one side of the support plate, a crank fixedly connected to the output end of the motor, a transverse slide rail fixedly connected to one side of the support plate, a slide frame slidably connected to the outer wall of the transverse slide rail, a longitudinal slide rail fixedly connected to one side of the slide frame, a connecting frame slidably connected to the outer wall of the longitudinal slide rail, a crank rotatably connected to one side of the connecting frame, a feeding assembly provided at the top of the connecting frame, and a limit assembly provided on the side wall of the bracket.

[0008] The feeding assembly includes a feeding rack, one side of which is fixedly connected to the other side of the connecting frame. Both the bracket and the feeding rack have multiple V-shaped grooves inside.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting plate and an arc-shaped plate. The limiting plate is disposed on the side wall of the bracket, and one side of the arc-shaped plate is fixedly connected to one side of the limiting plate.

[0011] As a further description of the above technical solution:

[0012] A fixing plate is fixedly connected to the side wall of the support frame, and the limiting plate is slidably connected to the top of the fixing plate.

[0013] As a further description of the above technical solution:

[0014] A support base is fixedly connected to the top of the fixed plate, and a support rod is fixedly connected to the top of the support base.

[0015] As a further description of the above technical solution:

[0016] A fixing block is provided on the outer wall of the support rod, and a sliding rod is slidably connected inside the fixing block.

[0017] As a further description of the above technical solution:

[0018] A spring is fitted on the outer wall of the slide rod, and one end of the spring is fixedly connected inside the fixing block.

[0019] As a further description of the above technical solution:

[0020] One end of the slide rod is fixedly connected to one side of the limiting plate, and the other end of the spring is fixedly connected inside the limiting plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the crank is driven to rotate by the output end of the motor, and the crank linkage connecting frame makes a compound movement in the horizontal and vertical directions on the longitudinal slide rail and the transverse slide rail, thereby driving the feeding frame to move. These structures work together to achieve the effect of flexibly controlling the number of steel pipes fed out at one time, solving the problem of difficulty in accurately controlling the number of feeds, resulting in low production efficiency and insufficient processing accuracy, thereby improving the processing efficiency of steel pipes.

[0023] 2. In this utility model, the pressure generated on the limiting plate when the steel pipe is placed causes the limiting plate to overcome the spring force and slide within the fixed block through the sliding rod. At the same time, the arc plate fits against the outer surface of the steel pipe. These structures work together to achieve the effect of the limiting plate adaptively adjusting the contact pressure according to the diameter of the steel pipe and stabilizing the limiting steel pipe. This solves the problem of steel pipes being prone to displacement, falling, or damage due to extrusion in traditional feeding devices, thereby improving the stability during feeding.

[0031] 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.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a precision steel pipe quantitative feeding device, including a support frame 1, a bracket 2 fixedly connected to the top of the support frame 1, a support plate 3 fixedly connected inside the support frame 1 to support a motor 4 and related transmission components, a motor 4 fixedly connected to one side of the support plate 3, a crank 5 fixedly connected to the output end of the motor 4, a transverse slide rail 6 fixedly connected to one side of the support plate 3, a slide frame 7 slidably connected to the outer wall of the transverse slide rail 6, a longitudinal slide rail 8 fixedly connected to one side of the slide frame 7, and a connecting frame 9 slidably connected to the outer wall of the longitudinal slide rail 8. The sliding of the slide frame 7 enables the feeding component to move laterally, while the connecting frame 9 achieves precise longitudinal feeding through the guidance of the longitudinal slide rail 8. The cooperation of the two allows the feeding of the steel pipe to be adjusted in multiple directions. The crank 5 is rotatably connected to one side of the connecting frame 9. The crank 5, through its connection with the motor 4, rotates to drive the movement of the slide frame 7 and the connecting frame 9. A feeding component is provided on the top of the connecting frame 9, and a limit component is provided on the side wall of the bracket 2.

[0033] The feeding assembly includes a feeding rack 10, which is fixedly connected to the other side of the connecting frame 9 on one side. Both the bracket 2 and the feeding rack 10 have multiple V-shaped grooves 11 inside to ensure that the steel pipe will not deviate or get stuck during the feeding process.

[0034] Reference Figure 1 , Figure 4 and Figure 5The limiting assembly includes a limiting plate 17 and an arc-shaped plate 18. The limiting plate 17 is disposed on the side wall of the bracket 2. One side of the arc-shaped plate 18 is fixedly connected to one side of the limiting plate 17 to prevent unnecessary displacement of the steel pipe due to inertia or other reasons during the conveying process, thus ensuring the feed rate and stability of the steel pipe. A fixing plate 12 is fixedly connected to the side wall of the support frame 1. The limiting plate 17 is slidably connected to the top of the fixing plate 12. A support seat 13 is fixedly connected to the top of the fixing plate 12. A support rod 14 is fixedly connected to the top of the support seat 13. The outer wall of the support rod 14 is provided with There is a fixed block 15, and a slide rod 16 is slidably connected inside the fixed block 15. A spring 19 is sleeved on the outer wall of the slide rod 16. One end of the spring 19 is fixedly connected to the inside of the fixed block 15, and one end of the slide rod 16 is fixedly connected to one side of the limiting plate 17. The other end of the spring 19 is fixedly connected to the inside of the limiting plate 17. The spring 19 is designed to provide restoring force to ensure that the slide rod 16 can return to its original position after being affected by external force. The adjustment function of the spring 19 allows the limiting plate 17 to be finely adjusted as needed, thereby precisely controlling the position of the steel pipe during the feeding process.

[0035] Working principle: When using this steel pipe quantitative feeding device, a certain number of steel pipes are first placed in multiple V-shaped grooves 11 inside the bracket 2. Then, the motor 4 is started, and its output end drives the crank 5 to rotate. When the crank 5 rotates, it will drive the connecting frame 9 to move, so that the connecting frame 9 slides on the longitudinal slide rail 8. At the same time, the connecting frame 9 slides on the transverse slide rail 6 through the slide 7, thereby making the connecting frame 9 perform compound movements in the horizontal and vertical directions, which in turn drives the feeding frame 10 to move. Each movement of the feeding frame 10 can feed out one or more steel pipes in the V-shaped grooves 11. The specific number can be controlled by adjusting the layout of the feeding frame 10 and the V-shaped grooves 11, thereby realizing the function of quantitative feeding.

[0036] During the feeding process, the limiting plate 17 is set on the side wall of the bracket 2. Its function is to limit the precision steel pipe placed on the bracket 2 and prevent the steel pipe from shifting or falling during the feeding process. The arc design of the arc plate 18 can better fit the outer surface of the steel pipe and enhance the limiting effect. When the steel pipe is placed on the bracket 2, the steel pipe will exert a certain pressure on the limiting plate 17, so that the limiting plate 17 overcomes the elastic force of the spring 19 and slides in the fixed block 15 through the slide rod 16, thereby adapting to steel pipes of different diameters. The spring 19 can provide a buffer and reset force to ensure that the limiting plate 17 always maintains a suitable contact pressure with the steel pipe, which can effectively limit the movement without causing excessive squeezing damage to the steel pipe, thereby meeting the feeding requirements of steel pipes of different specifications.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
