Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0014] See Figures 1-6To address the problems mentioned in the background section, this utility model provides a pipe bending device for an air conditioner compressor to solve the aforementioned technical problems. The technical solution is as follows: A pipe bending device for an air conditioner compressor includes: a base 110, a side plate 120, a turntable 130, a bending roller 140, a fixed-length baffle 150, a limiting structure 160, and a drive handle 170. Side plate 120 is fixedly connected to one side of base 110; rotating shaft 171 is rotatably connected to side plate 120; The drive handle 170 is fixedly connected to one side of the rotating shaft 171; the turntable 130 is coaxially fixedly connected to the rotating shaft 171. The bending roller 140 is mounted on the rotating shaft 171 and is located on the opposite side of the drive handle 170; The fixed-length baffle 150 includes a connecting plate 151 and a positioning plate 152 that is perpendicularly connected to the connecting plate 151; the connecting plate 151 on the fixed-length baffle 150 is located between the bending roller 140 and the turntable 130 and is fixed on the surface of the turntable 130. The limiting structure 160 is fixed on the surface of the turntable 130 and located above the bending roller 140.

[0015] In this embodiment, the limiting structure 160 includes a bolt rod 161, a nut 162, and a limiting block 163; A radial elongated hole 131 is provided on the turntable 130, and the bolt rod 161 passes through the radial elongated hole 131; The limiting block 163 is fixedly connected to the end of the bolt rod 161 and is set on the same side as the bending roller 140; Nut 162 is locked onto bolt rod 161 and is located on the opposite side of limit block 163.

[0016] It should be noted that the functions of each structure in the limiting structure 160 are as follows: The bolt rod 161 passes through the radial elongated hole 131 of the turntable 130 and can slide radially, causing the end limit block 163 to move closer to or away from the bending roller 140, thereby adjusting the gap between the two and adapting to brass tubes of different diameters. Nut 162 locks the bolt rod 161 on the opposite side of the limiting block 163, which can fix the adjusted position of the limiting structure 160 and ensure that the limiting block 163 does not loosen during the bending process; The limiting block 163 cooperates with the bending roller 140 to abut against the tube from the outside, preventing it from radially shifting during bending and ensuring the forming accuracy and number of turns of the annular segment.

[0017] In this embodiment, the bending roller 140 is sleeved on the rotating shaft 171, and the end of the rotating shaft 171 is locked with a nut 172 for axially fixing the bending roller 140.

[0018] In this embodiment, the base 110 has mounting holes at its corners. The mounting holes 111 are used for fasteners to pass through, so as to fix the entire pipe bending device to the external installation position.

[0019] In this embodiment, the drive handle 170 is provided with anti-slip texture; the anti-slip texture on the drive handle 170 is used to increase friction and prevent slippage during operation.

[0020] The present invention provides a method for bending pipe fittings for an air conditioner compressor using a bending device, as follows: (1) Fixing and initial adjustment of the device: Fix the entire device to the external installation position (such as a workbench) with bolts and other fasteners through the mounting holes 111 at the corners of the base 110 to ensure that the device does not shake during the bending process. According to the diameter of the brass tube to be processed, loosen the nut 162 of the limiting structure 160, slide the bolt rod 161 along the radial long hole 131 of the turntable 130 to make the gap between the limiting block 163 and the bending roller 140 match the diameter of the tube. After the adjustment is completed, tighten the nut 162 to fix the position of the limiting block 163.

[0021] (2) Brass tube clamping and positioning: The straight end 220 of the brass tube of a specific length is placed against the positioning plate 152 of the fixed-length baffle 150 to ensure that the length of the straight end 220 meets the design requirements (the distance between the positioning plate 152 and the bending roller 140 is preset to the standard length of the straight end 220). The section of the brass tube to be bent is placed between the bending roller 140 and the limiting block 163. At this time, the tube is constrained by the limiting block 163 and the bending roller 140 to prevent radial movement during bending.

[0022] (3) Annular segment bending process: The operator holds the drive handle 170 and rotates the handle. The drive handle 170 drives the rotating shaft 171 to rotate, which in turn drives the turntable 130 fixed on the rotating shaft 171, the fixed length baffle 150, and the bending roller 140 sleeved on the rotating shaft 171 to rotate together. As it rotates, the brass tube is gradually bent around the bending roller 140 as the axis: the limiting block 163 rotates synchronously with the turntable 130 and always fits against the outside of the tube to ensure the bending trajectory is stable; when the fixed length baffle 150 rotates with the turntable, the positioning plate 152 always presses against the straight end 220 to ensure that the length of the end remains unchanged. Continue to rotate the drive handle 170 to the preset number of turns. At this time, the brass tube forms two tightly coiled annular segments around the bending roller 140, and the annular segments transition smoothly with the straight end 220.

[0023] (4) Finishing the processing and removing the pipe: After completing the bending of the two ring segments 210, the operator gently pushes the brass pipe along the axial direction of the bending roller 140 to separate the formed ring segments 210 from the bending roller 140, thus obtaining the finished pipe containing two ring segments 210 and a straight end of a specific length.

[0024] The present invention provides a pipe bending device for an air conditioner compressor, which has the following advantages: The present invention has a simple structural design, high cost adaptability, no need to purchase expensive CNC equipment, simple structure and easy-to-obtain parts, which conforms to the principle of economic efficiency in small-batch production and avoids equipment idleness and waste.
