Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, and more specifically, to a metal pipe bending device for an air compressor. Background Technology

[0002] In the production of air compressors, bending of metal pipes is one of the key processes. Traditional cold bending processes can easily lead to pipe wall deformation, wrinkles, or even breakage, affecting sealing and service life. Although existing technologies use hydraulic or mechanical pipe bending equipment, there are still problems such as insufficient bending accuracy and pipe springback. Especially for high-hardness metal pipes, multiple corrections and subsequent grinding are often required, increasing production costs and time consumption.

[0003] Most existing pipe bending devices use direct mechanical force to forcibly bend the pipe in a cold state. This not only requires a large driving force but also easily causes stress concentration on the pipe wall, resulting in indentations or wrinkles. Some improved solutions attempt to heat the entire metal pipe, but this is energy-intensive and inefficient, and it is difficult to accurately control the heating area, leading to a decline in pipe performance or uneven deformation. This cannot meet the high-precision and high-quality bending requirements of compressor pipes. Therefore, in order to address the above technical problems, an air compressor metal pipe bending device is proposed here. Utility Model Content

[0004] The purpose of this invention is to provide an air compressor metal pipe bending device that combines gravity filtration, centrifugal separation and mechanical scraping to achieve triple purification. By rotating the oil storage cylinder to throw out the oil and remove impurities, and then using a liftable scraper ring to scrape off the residual oil along the inner wall, the device can be completely cleaned up, thus avoiding residual loss and keeping the inside of the device clean. This significantly improves filtration efficiency and reduces maintenance requirements.

[0005] This utility model is achieved through the following technical solution: An air compressor metal pipe bending device includes an operating table.

A heating mechanism is installed inside the second mounting groove. A rotating rod is rotatably connected to the upper side of the operating table. A bending mechanism is installed on the upper side of the rotating rod.

[0006] Preferably, a rotating column is rotatably connected to the upper side of the operating table, and a mounting base is fixedly connected to the upper side of the rotating column.

The connecting seat is fixedly connected to the inner side of the second mounting groove, and the heating rod is fixedly connected to the outer side of the connecting seat, with the end of the heating rod located inside the first mounting groove.

[0010] Preferably, a storage battery is fixedly connected to the upper side of the mounting base, and the storage battery and the mounting base are electrically connected.

[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] Please see Figures 1-6 The present invention proposes an air compressor metal pipe bending device, including an operating table 1, a mounting base 2, and a rotating rod 12. The operating table 1 serves as the basic support platform for the entire device, providing the mounting base and working space for each component. Two sets of symmetrically arranged mounting bases 2 are rotatably connected to the upper side of the operating table 1. The mounting bases 2 are used to clamp and position the metal pipe to be processed. A guide mechanism is installed between the mounting bases 2 and the operating table 1 to ensure that the mounting bases 2 maintain a stable trajectory during movement.

[0017] The upper side of the mounting base 2 is provided with a first mounting groove 6, which is used to place the metal tube to be bent. The upper side of the first mounting groove 6 is detachably connected with a clamping plate 7 by bolts. The clamping plate 7 and the first mounting groove 6 cooperate to form a complete circular clamping structure to ensure that the metal tube is firmly fixed. The cross-section of the first mounting groove 6 and the clamping plate 7 is a semi-circular structure. The semi-circular structure design facilitates the quick installation and removal of the metal tube. A second mounting groove 8 is provided on one side of the first mounting groove 6. The second mounting groove 8 is used to accommodate the heating mechanism to provide local heating for the metal tube. The heating mechanism is installed inside the second mounting groove 8. The heating mechanism is used to precisely heat and soften the metal tube. The upper side of the operating table 1 is rotatably connected with a rotating rod 12. The rotating rod 12 serves as the power input component of the bending mechanism. The bending mechanism is installed on the upper side of the rotating rod 12. The bending mechanism realizes the bending and shaping of the metal tube through mechanical traction.

[0018] The upper side of the control panel 1 is rotatably connected to a rotating column 3, which provides a fulcrum for the mounting base 2. The mounting base 2 is fixedly connected to the upper side of the rotating column 3 to ensure that the mounting base 2 can rotate stably around the rotating column 3 as the axis.

[0019] The guiding mechanism includes a slot 4 and a slider 5. The slot 4 is used to limit the movement trajectory of the slider 5. The slot 4 is located on the upper side of the operating table 1 and is an arc-shaped mechanism with the rotating column 3 as the axis. The arc-shaped mechanism ensures that the mounting base 2 moves along a predetermined path. The slider 5 is fixedly connected to the bottom of the mounting base 2. The slider 5 and the slot 4 cooperate to achieve precise guidance of the mounting base 2.

[0020] Both the slot 4 and the slider 5 have a T-shaped cross-section. The T-shaped structure design enhances the stability and anti-offset capability of the guide mechanism. The slider 5 is limited and slidably connected to the inside of the slot 4 to ensure that the mounting base 2 will not deviate from the predetermined trajectory during movement.

[0021] The heating mechanism includes a connecting seat 9 and an electric heating rod 10. The connecting seat 9 provides a fixed support for the electric heating rod 10. The connecting seat 9 is fixedly connected to the inner side of the second mounting groove 8 to ensure that the heating mechanism is installed stably. The electric heating rod 10 is fixedly connected to the outside of the connecting seat 9. The electric heating rod 10 acts as a heat source to locally heat the metal tube. The end of the electric heating rod 10 is located inside the first mounting groove 6 to ensure that the heat is directly applied to the part of the metal tube that needs to be bent.

[0022] A battery 11 is fixedly connected to the upper side of the mounting base 2. The battery 11 provides a stable power supply for the heating mechanism. The battery 11 is electrically connected to the connecting base 9 to ensure that the heating rod 10 can work normally.

[0023] The bending mechanism includes a winding reel 13 and a steel cable 14. The winding reel 13 is used to wind the steel cable 14 and generate traction force. The winding reel 13 is fixedly connected to the top of the rotating rod 12. The rotation of the rotating rod 12 drives the winding reel 13 to move. The steel cable 14 is fixedly connected to the outside of the winding reel 13. The steel cable 14 serves as the traction medium to transmit tension. There are two sets of steel cables 14, and the ends of the two sets of steel cables 14 are symmetrically welded to the outside of the mounting base 2 to ensure that the force on both sides of the mounting base 2 is even. A handle 15 is fixedly connected to the top of the winding reel 13. The handle 15 allows the operator to manually control the bending process.

[0024] Two sets of symmetrically arranged dials 16 are slidably connected to the upper side of the operating table 1. The dials 16 are used to display the bending angle in real time. The dials 16 are installed below the mounting base 2, which makes it easy for the operator to observe and adjust the bending accuracy.

[0025] The working principle of an air compressor metal pipe bending device based on an embodiment is as follows: during operation, the metal pipe to be processed is placed in the first mounting groove 6, and the clamping plate 7 is fastened by bolts to stably clamp the metal pipe. Then, the heating mechanism is activated, and the battery 11 supplies power to the connecting seat 9, driving the heating rod 10 to heat up. The end of the heating rod 10 extends to the inside of the first mounting groove 6, directly radiating heat to the part of the metal pipe to be bent, softening the material and significantly improving its plasticity.

[0026] After the metal tube is heated and softened, the operator rotates the rotating rod 12 by the handle 15, which drives the take-up reel 13 at the top to rotate. The take-up reel 13 winds two sets of steel cables 14. As the take-up reel 13 rotates, it tightens the steel cables 14. The steel cables 14 generate traction force, which pulls the two mounting seats 2 to rotate on the operating table 1 with the rotating column 3 at its bottom as the axis. During this process, the slider 5 slides within the T-shaped arc groove 4 to ensure that the mounting seat 2 and the end of the metal tube it holds move smoothly along a precise predetermined arc trajectory. The part of the metal tube that has been heated and softened is forced to bend during the opposite or opposite rotational movement of the two mounting seats 2. The scale 16 can be used to assist in observing or controlling the bending angle.

[0027] By first heating and softening the metal tube and then precisely bending it, the preheating of the heating rod 10 effectively reduces the yield strength of the metal tube, significantly reduces the external force required for bending, and greatly reduces the risk of wrinkles or flattening of the tube wall due to stress concentration during cold bending. This significantly improves the forming quality and roundness of the bending point, reduces or even avoids the burden of subsequent grinding, polishing and repair of the bending point, and improves production efficiency and product quality.

[0028] 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.
