Description

Technical Field

[0001] This utility model relates to the technical field of straightening devices, specifically a straightening device for precision machining of oil pipeline steel. Background Technology

[0002] Oil pipelines are used to transport oil. They are usually made of steel and shaped like pipes to meet the needs of oil production, storage, and transportation. During the processing of oil pipelines, straightening devices are used to straighten them to avoid bending and affecting product quality. A straightening device is a device used to correct shape deviations of metal materials, restoring materials with irregular shapes such as bends and twists to a relatively straight state. It mainly changes the internal stress distribution of the material by applying external force to make the material reach the required straightness standard. Its core components usually include straightening rollers, pressure regulating mechanisms, transmission systems, and frames. The straightening rollers are the components that act directly on the material. By rotating and contacting the material surface, they apply pressure to the material. The pressure regulating mechanism is used to control the amount of pressure applied by the straightening rollers to the material. The transmission system provides power to the straightening rollers so that they can rotate stably.

[0003] In the existing pipeline processing, straightening machines are used to straighten the bent parts. However, the existing straightening machines require workers to manually lift the steel pipe at the inlet end, align it, and then receive the material from the other end. This increases the workload of workers and reduces the practicality of the overall device. Therefore, it is necessary to propose a straightening device for precision machining of oil pipeline steel. Summary of the Invention

[0004] The purpose of this invention is to provide a straightening device for precision machining of oil pipeline steel, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a straightening device for precision machining of oil pipeline steel, comprising a roller conveyor, a baffle fixedly installed on the inner side of the roller conveyor, a buffer pad fixedly installed on the front side of the baffle, an automatic feeding mechanism fixedly installed on the front side of the roller conveyor, a straightening machine arranged on the left side of the roller conveyor, a guide ring fixedly installed on the right side of the straightening machine, a roller conveyor second arranged on the left side of the straightening machine, an automatic receiving mechanism fixedly installed on the front side of the roller conveyor second, a support plate fixedly installed on the bottom inner side of the roller conveyor second, and a top-loading cylinder fixedly installed on the upper end of the support plate;

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This straightening device for precision machining of oil pipeline steel, through the setting of an automatic feeding mechanism, can place the pipelines sequentially on the pipe rack. Due to the slope setting of the pipe rack, the oil pipeline will roll to one side of the feeding rack and be located on the top plate with the same slope. Then, the cylinder drives the guide rod to push the top plate upward, causing the oil pipeline to rise and roll onto the guide slope plate and enter the roller conveyor. The roller conveyor automatically feeds the pipeline into the straightening machine, eliminating the intermittent time in the manual operation process, enhancing continuous operation, reducing labor intensity and labor costs, and improving processing efficiency.

[0015] This straightening device for precision machining of oil pipeline steel, through the setting of an automatic material collection mechanism, allows the straightened oil pipeline to enter the roller conveyor. The top material cylinder pushes the material feeding rod upward, causing the material feeding rod to drive the movable shaft to rotate, creating a slope on the material feeding rod. This allows the oil pipeline to roll from the material feeding rod onto the stacking rod, thus automatically collecting the material and promptly removing the finished product, reducing equipment downtime.

A second loading rack 403 is fixedly installed on the front side of the pipe rack 402. A guide slope plate 404 is fixedly installed on the upper end of the first loading rack 401. A cylinder body 405 is fixedly installed on the rear side of the first loading rack 401. A guide rod 406 is provided on the inner side of the cylinder body 405. A top plate 407 is fixedly installed on the upper end of the guide rod 406. Through the automatic feeding mechanism 4, pipes can be placed on the pipe rack 402 in sequence. Due to the slope of the pipe rack 402, the oil pipe will roll to one side of the first loading rack 401 and be located on the top plate 407 with the same slope. Then, the cylinder body 405 drives the guide rod 406 to push the top plate 407 upward, so that the oil pipe rises and rolls onto the guide slope plate 404 and enters the roller conveyor 1. The roller conveyor 1 automatically feeds the oil pipe into the straightening machine 5, eliminating the intermittent time in the manual operation process, enhancing continuous operation, reducing labor intensity and labor costs, and improving processing efficiency.

[0023] Please see Figure 2-4In this embodiment, the automatic receiving mechanism 8 includes a receiving frame 1 801, a stacking rod 802, a receiving frame 2 803, a shaft frame 804, a movable shaft 805, and a discharge rod 806. The stacking rod 802 is fixedly installed on the rear side of the receiving frame 1 801, and the receiving frame 2 803 is fixedly installed on the rear side of the stacking rod 802. The shaft frame 804 is fixedly installed on the left side of the receiving frame 2 803, and the movable shaft 805 is rotatably installed on the right side of the shaft frame 804. The discharge rod 806 is fixedly installed on the front side of the movable shaft 805. Through the automatic receiving mechanism 8, after the oil pipe passes through the straightened section and enters the roller conveyor 2 7, the top cylinder 10 pushes the discharge rod 806 upwards, causing the discharge rod 806 to drive the movable shaft 805 to rotate. This creates a slope on the discharge rod 806, causing the oil pipe to roll from the discharge rod 806 onto the stacking rod 802, thus automatically... The receiving mechanism ensures timely removal of finished products, reducing equipment downtime. Multiple baffles 2 are located inside the roller conveyor 1. Buffer pads 3 are made of rubber to cushion the impact of feeding and prevent falling. Pipe rack 402 is fixedly installed between feed rack 1 401 and feed rack 2 403. Pipe rack 402 has a ramp with an angle of 6-8°. Top plate 407 is at the same height as pipe rack 402 and has the same ramp. Guide plate 404 is located at the upper end of roller conveyor 1 and feed rack 1 401 to facilitate lifting of oil pipes. Stacking rod 802 is fixedly installed between receiving rack 1 801 and receiving rack 2 803. Shaft brackets 804 are fixedly installed on both the left and right sides of receiving rack 2 803. Three unloading rods 806 are located in front of movable shaft 805. Top cylinder 10 is installed at the lower end of unloading rod 806.

[0024] Working principle: First, the pipes are placed sequentially on the pipe rack 402. Due to the slope of the pipe rack 402, the oil pipes roll to one side of the loading rack 401 and are located on the top plate 407 with the same slope. Then, the cylinder 405 drives the guide rod 406 to push the top plate 407 upward, causing the oil pipes to rise and roll onto the guide slope plate 404 and enter the roller conveyor 1. The roller conveyor 1 automatically feeds the pipes into the straightener 5, eliminating the intermittent time in the manual operation process and enhancing efficiency. Continuous operation reduces labor intensity and labor costs, and improves processing efficiency. Then, through the setting of the automatic material receiving mechanism 8, after the oil pipe passes through the straightened oil pipe and enters the roller conveyor 7, the top material cylinder 10 pushes the unloading rod 806 upward, causing the unloading rod 806 to drive the movable shaft 805 to rotate, so that the unloading rod 806 forms a slope, thereby causing the oil pipe to roll from the unloading rod 806 to the stacking rod 802, thus automatically receiving the material, removing the finished product in time, and reducing equipment idle time.
