[0002] In central air conditioning installation projects, pipe bending machines are indispensable and important tools used to accurately bend metal pipes into specific shapes to adapt to complex installation environments. However, traditional pipe bending machines have a series of problems during operation, especially when dealing with pipes that require multiple bending points. These problems are particularly prominent.

[0003] Traditional pipe bending machines often lack effective fixing devices during the bending process, which causes the pipes to shake easily when subjected to stress, thereby affecting the accuracy and efficiency of the bending. At the same time, when the pipes require two or more bending points, due to the large stress during bending, the operator needs to spend a lot of time and energy to adjust the position and angle of the pipes, which increases the difficulty of work and safety hazards. In addition, due to the lack of precise control systems and positioning devices, traditional pipe bending machines are difficult to achieve high-precision angle control during the bending process, which often leads to deviations in the bending angle and affects the installation quality. Traditional pipe bending machines are often designed for specific types of pipes. When different types of pipes need to be processed, corresponding adjustments or mold replacements are required, which greatly reduces the flexibility and applicability of the equipment.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Please refer to the attached Figure 1-7 The pipe bending machine for central air conditioning installation in this embodiment includes a base plate 1, a bending plate 2 is rotatably connected to the base plate 1, a first clamping plate 3 is slidably connected to the side of the bending plate 2, a second clamping plate 4 is provided on the side of the first clamping plate 3, a support platform 5 is installed between the second clamping plate 4 and the base plate 1, and a corner fixer 6 is provided on the side of the support platform 5.

[0026] The bottom plate 1 is provided with fixing holes at the four corners, and the bottom plate 1 is fixed to the base or the ground by bolts. The stability of the bottom plate 1 is ensured during the force application of the bending plate 2. The bending plate 2 and the first clamping plate 3 on the bottom plate 1 rotate synchronously, and the first clamping plate 3 can also move relative to the bending plate 2. The working principles of the bending plate 2 and the first clamping plate 3 are the same as those of a normal bending device, but ordinary bending devices are not suitable for multiple bending. The side corner fixers 6 of the support platform 5 are used to fix the bent pipe fittings, and the part of the pipe fitting to be bent extends into the bending plate 2, so that the pipe fittings can be bent twice or even multiple times. When in use, the two bent parts of the pipe fittings can be placed at different angles in space, so that the bending shape of the pipe fittings can better fit the needs of the air conditioner during actual installation.

[0027] The corner fixer 6 includes an arc-shaped bracket 601, a slide groove 602 is provided on the bracket 601, a fixed platform 603 that revolves around the center of the bracket 601 is slidably connected in the slide groove 602, a limiting wheel 604 is installed on the fixed platform 603, a fixed wheel 605 is provided on the side of the limiting wheel 604, and the fixed wheel 605 is slidably connected to the fixed platform 603.

[0028] The bracket 601 of the corner fixture 6 is a semicircular arc structure, the slide 602 is located on the bracket 601, and the fixed platform 603 interacts along the slide 602. The center of the fixed pipe on the fixed platform 603 is located at the center of the bracket 601. The fixed platform 603 revolves along the semi-circular structure of the bracket 601. The bending disk 2 can only bend horizontally. As the fixed platform 603 rotates on the bracket 601, the bending disk 2 bends the pipe. The angles formed in the space at the two bending parts are different, so that the device can be applied to the bending requirements of pipes at different angles. The fixed platform 603 has three upper limit wheels 604 and one fixed wheel 605. The fixed wheel 605 and the fixed platform 6 03, under the action of the push rod, the fixed wheel 605 can slide horizontally on the fixed platform 603. When fixed, the fixed wheel 605 is moved away from the limiting wheel 604 by the push rod. After the pipe is placed, the fixed wheel 605 is moved closer to the side of the limiting wheel 604 by the push rod, so that the limiting wheel 604 and the fixed wheel 605 clamp the pipe in the middle. After the pipe is clamped, the fixed platform 603 is moved, and the fixed platform 603 will drive the pipe to revolve around the center of the pipe, thereby changing the angle between the bent part of the pipe and the horizontal plane. After the left side of the pipe is horizontally bent by the bending disk 2, the two bent parts of the pipe have a certain angle in space, so that the bent pipe is more in line with actual needs.

[0029] A driving motor is installed on the fixed platform 603, and the driving motor is fixedly connected to the driving gear 606. The driving motor drives the driving gear 606 to rotate, and the driving gear 606 is meshed with the tooth groove 607. Under the rotation of the driving gear 606, the driving gear 606 drives the fixed platform 603 to revolve around the bracket 601.

[0030] Furthermore, in order to improve the applicability of the corner fixer 6, the corner fixer 6 and the first slide 7 below can be rotated, and the corner fixer 6 and the first slide 7 can be rotated at a fixed angle of one hundred and eighty degrees. At the same time, a first slide rail 8 is installed between the first slide 7 and the base plate 1, and the first slide 7 can slide on the first slide rail 8. The distance between the corner fixer 6 and the bending disk 2 can be adjusted by sliding the slide rail, so that the distance between the two can be adapted to the actual length in reality; in order to place the pipe fittings between the corner fixer 6 and the bending disk 2 more stably, a clamp 9 is installed on the first slide 7, and the clamp 9 is a pneumatic clamp 9, which plays an auxiliary fixing role for the pipe fittings.

[0031] The clamping groove 10 is a semi-cylindrical structure. The clamping groove 10 on the bending plate 2, the first clamping plate 3 and the second clamping plate 4 can increase the contact area with the pipe fitting and increase the firmness of the fixation.

[0032] The first clamping plate 3 presses the pipe fittings through the first telescopic rod 12, and the second pressing plate presses the pipe fittings through the second telescopic rod 14. There is a gap between the support rod 11 and the support platform 5 in the initial position. When the bending disk 2 drives the pipe fittings to bend, the support platform 5 drives the second clamping plate 4 to move a certain distance along the second slide rail 13 toward the bending disk 2, so as to avoid the bending disk 2 breaking the pipe fittings during the bending process and improve the yield rate of pipe bending.

[0033] The adjustment groove 15 is a structure that radiates in straight lines around the center of the bracket 601. The adjustment bolt 16 can slide in the adjustment. The limiting wheel 604 can also be fixed at a specific position of the adjustment groove 15 by tightening the adjustment bolt 16. Through the adjustment bolt 16 and the adjustment groove 15, the three limiting wheels 604 can have different placement arcs, so that the limiting wheels 604 can fix pipes with different curvatures well.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
