Description

Technical Field

[0001] This utility model relates to the technical field of pipe bending machines, and in particular to a copper pipe bending machine for air conditioning processing. Background Technology

[0002] An air conditioner, also known as an air conditioning unit or chiller, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, cleanliness, and air velocity within a building or structure. It generally includes several major parts, such as cold / heat source equipment, a cold / heat medium distribution system, and terminal devices, along with other auxiliary equipment. Key components include water pumps, fans, and piping systems. The terminal devices are responsible for utilizing the distributed cold or heat to process the air, ensuring that the air parameters of the target environment meet requirements. An air conditioner consists of an indoor unit and an outdoor unit, connected by copper pipes to ensure the refrigerant flows smoothly through the circuit, carrying heat and facilitating heat exchange between the indoor and outdoor environments. When connecting the copper pipes to the indoor and outdoor units, it is crucial to ensure a reliable seal at the connection points to prevent leaks. Bending is sometimes necessary when laying the copper pipes.

[0003] The prior art Chinese utility model patent with application number CN201620230759.3 relates to an air conditioner copper pipe bending machine, which includes a stop plate, a bending die, a bending channel, a rotating rod, a pressure plate, a movable handle and a hinge shaft, and can bend copper pipes of different sizes.

[0004] However, in actual use, the stop plate of the above device is fixed. When bending copper pipes of different diameters, the gap between the copper pipe and the stop plate and the bending die causes a certain deviation between the actual bending angle and the required bending angle, which affects the normal use of construction. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a copper pipe bending machine for air conditioning processing, which uses a pipe bending device to bend copper pipes, and uses an adjustment device and auxiliary device to enable the equipment to adapt to bending copper pipes of different diameters, thereby reducing the error of the bending angle and improving the practicality of the device.

[0006] This utility model discloses a copper pipe bending machine for air conditioning processing; it includes a bending device, an adjusting device, and an auxiliary device. The adjusting device is installed on the bending device, and the auxiliary device is installed on the bending device. The bending device performs bending operations on copper pipes, and the adjusting device and auxiliary device enable the equipment to adapt to bending copper pipes of different diameters, thereby reducing the error of the bending angle and improving the practicality of the device.

[0007] Preferably, the pipe bending device includes a base, a main shaft, a central mold wheel, a U-shaped rotating frame, and a rotating wheel. The main shaft is mounted on the upper surface of the base, and the central mold wheel and the U-shaped rotating frame are fitted onto the upper part of the main shaft. The central mold wheel is located in the middle of the U-shaped rotating frame, and the rotating wheel is mounted on the U-shaped rotating frame. The copper pipe is placed between the central mold wheel and the rotating wheel, and one end of the copper pipe is limited by an auxiliary device. Then, the U-shaped rotating frame is rotated to drive the rotating wheel to work with the central mold wheel to bend the copper pipe, which improves the practicality of the device.

[0008] Preferably, the adjusting device includes a sliding groove frame, a sliding adjusting block, a shim, and a fastening bolt. The upper and lower end faces of the U-shaped rotating frame are respectively provided with strip-shaped holes. A set of sliding groove frames is provided on each of the upper and lower end faces of the U-shaped rotating frame. The upper and lower parts of the rotating wheel are respectively connected to a set of sliding adjusting blocks via rotating shafts. The upper and lower sets of sliding adjusting blocks are located in the upper and lower sets of sliding groove frames and can move within the sliding groove frames. The sliding adjusting blocks are provided with threaded holes. The fastening bolt passes through the shim and connects to the threaded holes on the sliding adjusting blocks. The position of the rotating wheel is adjusted by the sliding adjusting blocks and sliding groove frames, thereby enabling the equipment to adapt to copper pipes of different diameters and reducing angular errors caused by the gap between the copper pipe and the central mold wheel and the rotating wheel during bending. Rotating the fastening bolt causes the shim to press against the upper end face of the sliding groove frame, thereby fixing the position of the rotating wheel and improving the adaptability and practicality of the device.

[0009] Preferably, it also includes a first anti-slip texture and a second anti-slip texture. The first anti-slip texture is provided on the end face of the upper and lower sets of sliding groove frames that contact the pad, and the second anti-slip texture is provided on the lower end face of the pad. The first and second anti-slip textures increase the static friction force during the process of the pad pressing the sliding groove frame, preventing the rotating wheel from loosening and shifting during the bending process, thus improving the practicality of the device.

[0010] Preferably, it also includes an extension rod, a connecting seat, and a connecting bolt. The connecting seat is connected to the outer side of the U-shaped rotating frame. The connecting seat is provided with a circular through hole. The connecting seat is inserted into one end of the extension rod, and the two are connected by the connecting bolt passing through the extension rod and the connecting seat. The extension rod increases the lever arm length of the U-shaped rotating frame, reducing the labor intensity of the operator during the bending process. The connecting bolt facilitates quick disassembly during equipment transportation, reduces the space occupied by the equipment, and improves the practicality of the device.

[0011] Preferably, the auxiliary device includes a lead screw, a transverse sliding seat, a stop plate, and a rotary handle. A set of strip grooves is provided on the upper surface of the base, and the lead screw is horizontally installed in the strip grooves. The transverse sliding seat is located in the strip grooves and is connected to the lead screw by a nut. A stop plate is installed on the upper surface of the transverse sliding seat. One end of the lead screw passes through the base and extends to the outer side of the base, where it is connected to the rotary handle. By rotating the rotary handle according to the diameter difference of the copper tube, the lead screw is rotated, thereby adjusting the position of the transverse sliding seat and the stop plate. This allows the device to adapt to copper tubes of different diameters. The stop plate provides auxiliary limiting and fixing for one end of the copper tube, improving the practicality of the device.

[0012] Preferably, the device also includes a sleeve, a support arm, a limiting rod, and scale lines. The sleeve is fitted onto the lower part of the main shaft, and the support arm is connected to the side of the sleeve. A limiting rod is provided on the outer side of the upper end face of the support arm, and scale lines are provided on the upper end face of the base. The support arm is adjusted to the required position according to the bending requirements of the scale lines, thereby providing auxiliary reference for the bending process, reducing the situation of excessive or insufficient bending angle, and improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the copper pipe is bent by a pipe bending device, and the equipment can be adaptively adjusted when bending copper pipes of different diameters by adjusting and auxiliary devices, thereby reducing the error of the bending angle and improving the practicality of the device.
