Using an O-type heat exchanger bending machine, O-type heat exchangers of different specifications can be quickly clamped and bent, meeting the high-efficiency processing requirements of enterprises, and the bending effect is good, meeting the bending requirements of enterprises.

[0018] Specifically, the clamping mechanism includes: A connecting seat 202 is fixed on a connecting pipe 205. A first reducer 207 is installed at the bottom of the connecting seat 202. A first motor 206 connected to the first reducer 207 is installed on the first reducer 207. The lead screw 208 is located in the connecting seat 202, and the bottom end of the lead screw 208 is connected to the output end of the first reducer 207. The movable plate 209 has a threaded sleeve 210 fixed on one side to connect with the lead screw 208, and a lifting plate 211 fixed on the other side. A second clamping plate 213 that cooperates with the first clamping plate 212 is fixed on the lifting plate 211.

[0019] Furthermore, slide rails 214 are fixed at both ends of the side of the connecting seat 202, and first slide blocks 215 that are slidably connected to slide rails 214 are fixed at both ends of the side of the moving plate 209.

[0020] Specifically, support component 3 includes: Support 311 is located in machine 1; A support plate 301 is located above the bracket 311, and a movable block 303 is fixed on the bottom surface of the support plate 301. Hydraulic cylinder 302 is horizontally fixed on bracket 311, and the piston rod of hydraulic cylinder 302 is connected to moving block 303; Several gearboxes 304 are fixed to the bottom surface inside the machine base 1. The output shafts of several gearboxes 304 are connected to lifting rods 310. Several lifting rods 310 are fixed to the bottom of the bracket 311. A connecting shaft 306 is connected between every two adjacent gearboxes 304. The second motor 305 has its output end connected to the gearbox 304.

[0021] Furthermore, the bracket 311 is connected to the bottom surface of the machine base 1 by several telescopic rods 307.

[0022] Furthermore, the top surface of the bracket 311 is fixed with a first slide rail 308 at both ends, and the bottom surface of the support plate 301 is fixed with a second slide block 309 connected to the first slide rail 308 at both ends.

[0023] Specifically, the drive mechanism includes a second reducer 204, which is fixedly connected to the machine base 1 via a straight plate 201. Its output end is connected to a connecting pipe 205, and a third motor 203 connected to the second reducer 204 is provided on the second reducer 204.

[0024] Operating procedures First, place the O-ring heat exchanger to be bent stably on the support plate 301 of the support assembly 3. Then, start the second motor 305. The output end of the second motor 305 drives the gearbox 304 connected to it to rotate. The adjacent gearboxes 304 rotate synchronously through the coupling shaft 306. The output shaft of the gearbox 304 drives the lifting rod 310 to move the bracket 311 up and down, thereby adjusting the support plate 301 to a suitable height. Next, start the hydraulic cylinder 302. The piston rod of the hydraulic cylinder 302 pushes the moving block 303 connected to it to move. The support plate 301 drives the O-ring heat exchanger to move so that the end of the O-ring heat exchanger is located between the second clamping plate 213 and the first clamping plate 212.

[0025] Continue to start the first motor 206 in the clamping mechanism. The first motor 206 drives the first reducer 207 to run. The output end of the first reducer 207 drives the lead screw 208 to rotate. Since the threaded sleeve 210 is connected to the lead screw 208, and the moving plate 209 is slidably connected to the slide rail 214 on the connecting seat 202 through the first slide block 215, the rotation of the lead screw 208 drives the threaded sleeve 210 and the moving plate 209 to move down or up along the slide rail 214, thereby causing the second clamping plate 213 on the lifting plate 211 to approach or move away from the first clamping plate 212 at the bottom of the roller 216, until the second clamping plate 213 cooperates with the first clamping plate 212 to stably clamp the O-type heat exchanger.

[0026] Finally, the third motor 203 in the drive mechanism is started. The third motor 203 drives the second reducer 204 to run. The output end of the second reducer 204 drives the connecting pipe 205 to rotate, which in turn drives the roller 216 and the clamping mechanism to rotate. During the rotation, the roller 216 performs a bending operation on the clamped O-type heat exchanger.

[0027] Beneficial effects This O-type heat exchanger bending machine effectively solves the problems of clamping and bending in existing bending equipment, and has significant advantages.

[0028] In terms of clamping, a clamping mechanism consisting of a connecting seat 202, a first motor 206, a first reducer 207, a lead screw 208, a moving plate 209, a lifting plate 211, a first clamping plate 212, a second clamping plate 213, a slide rail 214, and a first sliding block 215 is provided. The first motor 206 drives the first reducer 207 to rotate the lead screw 208. Combined with the guiding effect of the slide rail 214 and the first sliding block 215, the distance between the second clamping plate 213 and the first clamping plate 212 can be quickly adjusted. This mechanism is suitable for O-type heat exchangers of different specifications and improves bending efficiency.

[0029] In terms of bending, during the bending process, the roller 216 drives the first clamping plate 212 and the second clamping plate 213 to rotate synchronously, which helps to improve the bending effect of the O-type heat exchanger and meets the bending requirements of the enterprise.
