The characteristics of light weight, corrosion resistance, and good electrical conductivity of aluminum tubes make coiled aluminum tubes the first choice for many industrial and daily applications. Especially for the aluminum tubes required inside air conditioners, the requirements for the coiling and forming of aluminum tubes are more stringent.

[0004] Although the above technical solution can achieve the purpose of accurately bending aluminum tubes by controlling the rotation degree by angle, in the actual production process, the workload of the aluminum tube coiling and bending device is extremely large. And considering the cost performance, usually the same coiling and bending device needs to bend aluminum tubes of different models, resulting in that the staff need to constantly change the molds, delaying the production progress and prone to safety accidents at the same time, greatly reducing the production efficiency of aluminum tubes. Content of the Utility Model

[0005] The purpose of the utility model is to provide a coiling and bending device for air-conditioning aluminum tube processing, and solve the problems in the prior art that in the actual production process, the workload of the aluminum tube coiling and bending device is extremely large. And considering the cost performance, usually the same coiling and bending device needs to bend aluminum tubes of different models, resulting in that the staff need to constantly change the molds, delaying the production progress and prone to safety accidents at the same time, greatly reducing the production efficiency of aluminum tubes.

[0006] The utility model provides the following technical solution: a coiling and bending device for air-conditioning aluminum tube processing, including a fixing plate. A fixing seat is arranged on the outer side wall of the fixing plate. The middle part of the outer side wall of the fixing seat is hollow and provided with a rotating seat. An activity arm is arranged on the outer side wall of the rotating seat. A coiling and bending mechanism is slidably connected to the upper top end of the activity arm.

[0007] With the above solution, the rotating base in the fixed base rotates to drive the movable arm to rotate, and then drives the bending mechanism to bend the aluminum tube.

[0008] As a preference of the above technical solution, the bending mechanism includes a support frame at the upper end of the movable arm and a chuck fixedly connected to the outer side wall of the support frame. A chassis is fixedly connected to the inner side wall of the chuck. A shaft seat is arranged at the center of the upper end of the chassis.

[0011] With the above solution, the driving rod and the driven rods all slide in the sliding seats on the outer side wall of the chassis. Through the connecting component arranged on the outer side wall of the driving rod, the driving rod can be well driven to displace. By rotating the handle, the screw rod rotates in the threaded hole on the outer side wall of the vertical plate, and one end gradually abuts against the connecting seat and then displaces, thereby driving the driving rod to displace, further driving the turntable to rotate, and thus driving the driven rods to tighten inward through the first connecting rod. By arranging the circular seats on the driving rod and the driven rods, the first mold and the second mold can better tighten the aluminum tube.

[0012] As a preference of the above technical solution, a sliding groove is opened at the upper end of the movable arm, a slider is arranged inside the sliding groove, and the slider is fixedly connected to the support frame.

[0019] With the above solution, the staff operates the movable arm through the operator to make the aluminum tube bend and form. The diameter of the die groove in the movable seat can be adjusted through the module in the die box.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the bending mechanism, it can adapt to aluminum tubes of different models, avoiding the time wasted in replacing the mold. By rotating the handle, the screw rod gradually abuts against the connecting seat, driving the driving rod to slide inside the sliding seat to drive the first connecting rod to move, and then driving the turntable to rotate. Thus, through the first connecting rod, the driven rod is driven to contract inward, so that the round seats at the upper ends of the driving rod and the driven rod are tightened. At the same time, the first mold and the second mold on them fully wrap the aluminum tube. Aluminum tubes of different diameters can be wrapped by adjusting the mold size. Only by synchronously replacing the corresponding module in the die groove can the bending work be carried out. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] As Figure 1 shown, the present invention provides a technical solution: a bending device for processing air-conditioning aluminum pipes, including a fixed plate 1, characterized in that: a fixed seat 101 is provided on the outer side wall of the fixed plate 1, the middle part of the outer side wall of the fixed seat 101 is hollow and provided with a rotating seat 102, a movable arm 103 is provided on the outer side wall of the rotating seat 102, and a bending mechanism 2 is slidably connected to the upper end of the movable arm 103. The rotation of the rotating seat 102 in the fixed seat 101 drives the movable arm 103 to rotate, and then drives the bending mechanism 2 to bend the aluminum pipe.

[0028] As Figure 1 and Figure 2 shown, the bending mechanism 2 includes a support frame 201 at the upper end of the movable arm 103 and a chuck 202 fixedly connected to the outer side wall of the support frame 201. The inner side wall of the chuck 202 is fixedly connected with a chassis 203. A shaft seat 204 is provided at the center of the upper end of the chassis 203. The outer wall of the shaft seat 204 is respectively rotatably connected with a turntable 205 and a support plate 206, and the support plate 206 is located above the turntable 205. Three first connecting rods 207 are annularly arranged on the outer side wall of the turntable 205. The ends of two of the first connecting rods 207 are rotatably connected with a driven rod 209, and the end of the other first connecting rod 207 is rotatably connected with a driving rod 208. The support frame 201 in the bending mechanism 2 and the chuck 202 fixed to the outer side wall can limit the aluminum pipe. Then, through the movement of the driving rod 208 inside, the first connecting rod 207 is driven, so as to drive the turntable 205 and the support plate 206 connected thereto to rotate in the shaft seat 204, and then drive the two driven rods 209 arranged in an annular array to move, so as to achieve the effect of inward tightening.

[0029] As Figure 3 andFigure 4 As shown, sliding seats 210 are arranged in an annular array on the outer side wall of the chassis 203. Both the driving rod 208 and the driven rod 209 slide inside the sliding seats 210. A connecting component 3 is arranged on the outer side wall of the driving rod 208. The connecting component 3 includes a connecting seat 301 arranged on the outer side wall of the driving rod 208. A vertical plate 302 is arranged on one side of the chassis 203 where the connecting seat 301 is located. A threaded hole 303 is opened on the outer side wall of the vertical plate 302. A screw rod 304 is threadedly connected inside the threaded hole 303. One end of the screw rod 304 abuts against the connecting seat 301, and the other end is provided with a rotating handle 305. Circular seats 211 are fixedly connected to the upper ends of the driving rod 208 and the driven rod 209. A first mold 212 and a second mold 213 are respectively fixedly connected to the upper ends of the circular seats 211. Both the driving rod 208 and the driven rod 209 slide in the sliding seats 210 on the outer side wall of the chassis 203. Through the connecting component 3 arranged on the outer side wall of the driving rod 208, the driving rod 208 can be well driven to displace. By rotating the handle 305, the screw rod 304 rotates in the threaded hole 303 on the outer side wall of the vertical plate 302, and one end gradually abuts against the connecting seat 301 and then displaces, thereby driving the driving rod 208 to generate displacement, further driving the turntable 205 to rotate, and thus driving the driven rod 209 to contract inward through the first connecting rod 207. By arranging the circular seats 211 on the driving rod 208 and the driven rod 209, the first mold 212 and the second mold 213 can be better driven to tighten the aluminum pipe.

[0030] As Figure 1As shown in the figure, a sliding groove 104 is provided at the top end of the movable arm 103. A slider 105 is arranged inside the sliding groove 104. The slider 105 is fixedly connected to the support frame 201. The support frame 201 can slide inside the sliding groove 104 through the slider 105, which can better cooperate with the movable arm 103 for the aluminum pipe bending work, and the support frame 201 is limited by the sliding groove 104. A rotating shaft 106 is rotatably connected to the top end of the fixed seat 101. The top end of the rotating shaft 106 is fixedly connected to a movable seat 107. A die groove 108 is provided on the outer wall of the movable seat 107. A threaded hole 109 is provided on the inner side wall of the die groove 108. The rotating shaft 106 on the fixed seat 101 can rotate with the rotation of the movable seat 107. The die groove 108 can better adapt to the size of the aluminum pipe, and the internal threaded hole 109 can replace the module 114 at any time. Legs 110 are fixedly connected to the bottom end of the fixed plate 1. A cylinder 111 is arranged on the top end of the fixed plate 1 on one side of the bending mechanism 2. The legs 110 at the bottom end of the fixed plate 1 can provide sufficient stability. The cylinder 111 on the top end of the fixed plate 1 can drive the aluminum pipe to displace. An operator 112 is arranged on the top end of the fixed plate 1 on one side of the fixed seat 101. A die box 113 is arranged on the top end of the fixed plate 1 on one side of the operator 112. A module 114 is arranged inside the die box 113. The staff operates the movable arm 103 through the operator 112 to work, so that the aluminum pipe is bent and formed. The diameter of the die groove 108 in the movable seat 107 can be adjusted through the module 114 in the die box 113.

[0031] Working principle: Start the cylinder 111 to send the aluminum pipe into the die groove 108 of the movable seat 107. Through the operator 112, the movable arm 103 slides in the sliding groove 104 and approaches the aluminum pipe until the first die 212 and the second die 213 in the bending mechanism 2 abut against the aluminum pipe. Start the movable arm 103 to rotate to bend the aluminum pipe. When a smaller-sized aluminum pipe needs to be bent, first rotate the handle 305 to drive the screw 304 thereon to rotate inside the threaded hole 303 of the vertical plate 302, so that one end of it abuts against the connecting seat 301, and then drive the driving rod 208 to slide and displace inside the sliding seat 210. When the driving rod 208 displaces, the first connecting rod 207 movably connected thereto will drive the turntable 205 to rotate, and synchronously drive the driven rod 209 to tighten. At the same time, it can drive the round seat 211, the first die 212 on the driving rod 208, and the second die 213 on the driven rod 209 to tighten synchronously, achieving the effect of clamping the aluminum pipe. Synchronously, the corresponding module 114 in the die box 113 is assembled in the die groove 108 through bolts to make the size match. On the contrary, if a larger-sized aluminum pipe needs to be bent, the first die 212 and the second die 213 can be adjusted accordingly by rotating the handle 305.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
