Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, in particular to a bending device for seamless steel pipe processing. Background Art

[0002] Seamless steel pipe is a tubular product without welded seams, typically made from a single metal or alloy. It is formed through hot and cold working processes to ensure its structural integrity and strength. During the manufacturing process, solid round steel is first perforated to form a hollow shell tube, which is then further processed into the required size and shape through processes such as rolling and drawing. Seamless steel pipe is widely used in multiple industries due to its high strength, good pressure resistance, uniform wall thickness, and excellent corrosion resistance, including oil and gas transportation, chemical industry, automobile manufacturing, building structures, aerospace, and machinery manufacturing. These applications often require steel pipes to have a high degree of reliability and safety, making seamless steel pipe the material of choice in many critical applications.

[0003] A seamless steel pipe bending machine is a type of industrial equipment specifically designed for bending seamless steel pipes. This machine is designed to process steel pipes without welds, which are generally stronger and more uniform than pipes with welds. Therefore, the bending process requires specialized skills and strength to ensure the quality and accuracy of the bent pipes. Seamless steel pipe bending machines can be divided into two types: manual and automatic (electric or hydraulic). Seamless steel pipe bending machines are widely used in many industries such as construction, machinery manufacturing, pipeline engineering, automobile manufacturing, and furniture making, especially in application scenarios where high-strength seamless steel pipes need to be bent.

[0004] The steel pipe bending machine in the existing technology usually bends the steel pipe through three sets of rollers. Although it meets the use requirements to a certain extent, it is found in actual use that the rollers of the bending machine are usually fixed with bolts, which makes it difficult to replace the rollers. It is impossible to quickly replace the corresponding rollers according to the size of the seamless steel pipe, resulting in low production efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a bending device for processing seamless steel pipes to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a bending device for processing seamless steel pipes, comprising a base, an adjustment mechanism fixedly installed on the top of the base, two sets of adjustment mechanisms rotatably installed on the top of the base, a roller rotatably installed inside the adjustment mechanism, a quick-loading mechanism movably installed on one side of the roller, a roller fixedly installed on one side of the roller through the quick-loading mechanism, and characterized in that: the quick-loading mechanism includes an insertion cylinder, a locking pin is slidably installed inside the insertion cylinder, a plurality of locking balls are movably installed inside the insertion cylinder, an unlocking groove is provided at one end of the locking pin, and a locking groove is provided inside the roller.

[0007] Preferably, a plurality of limit blocks are fixedly mounted on one side of the rotating roller, a limit groove corresponding to the limit blocks is opened inside the roller, and a fixing plate is fixedly mounted on the outer wall of the insertion cylinder.

[0008] Preferably, a plurality of slide grooves are provided on the top of the insertion tube, a fixed groove is provided on one side of the slide groove, a limiting protrusion is slidably installed inside the slide groove, and the limiting protrusion is fixedly installed on the outer wall of the locking pin.

[0009] Preferably, the top of the locking pin is provided with anti-slip grooves, the top of the insertion cylinder is fixedly mounted with a spring, and one side of the base is fixedly mounted with a power component.

[0010] Preferably, the adjustment mechanism includes a mounting frame, a turntable is rotatably mounted on the top of the mounting frame, a screw is internally threadedly connected to the turntable, a mounting plate is fixedly mounted on the bottom of the screw, and one group of rollers is fixedly mounted on the bottom of the mounting plate.

[0011] Preferably, two groups of limiting columns are fixedly installed inside the mounting frame, and the mounting plate is slidably installed on the outer walls of the limiting columns.

[0012] Preferably, a plurality of joysticks are fixedly mounted on the outer wall of the turntable.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the bending device for processing seamless steel pipes;

[0014] 1. The steel pipe is supported by two sets of rollers and rollers installed on the top of the base. The steel pipe is squeezed by the rollers and rollers at the bottom of the adjustment mechanism. The power component drives the two sets of rollers and rollers installed on the top of the base to rotate, driving the steel pipe to move inside the three sets of rollers to bend.

[0015] The locking ball is squeezed toward the outer wall of the insertion tube by the locking pin, so that the locking ball is stuck in the locking groove to fix the quick-installing mechanism to the inside of the roller, and then the roller is fixed to one side of the roller by the fixing plate. The locking pin is pressed down to make the limiting protrusion displace inside the limiting protrusion. After displacing to the bottom, the locking pin is rotated. Under the action of the spring, the limiting protrusion rebounds to the inside of the limiting protrusion, so that the unlocking groove is away from the locking ball, ensuring the stability of the lock. When unlocking is required, the rotating fixing groove is pressed down again, and the limiting protrusion can rebound to the top of the slide groove under the action of the spring, so that the unlocking groove is displaced to one side of the locking ball to complete the unlocking. In this process, the friction force on the top of the locking pin is increased by the anti-slip groove, which makes it convenient for the staff to operate the locking pin. The cooperation between the limiting block and the limiting groove prevents the roller from rotating on the outer wall of the roller to prevent loosening.

[0016] 2. Through the coordination between the mounting frame, turntable and screw, the mounting plate can follow the screw to move up and down when the turntable rotates, thereby achieving the purpose of changing the position of the roller at the bottom of the mounting plate. In this process, the limit column is used to limit the limit column and the screw to rotate with the turntable, making the displacement of the mounting plate more stable, and the user can use the joystick to rotate the turntable conveniently.
