The two indicating blocks 5 are respectively fixedly installed at both ends of the bending machine body 1;

[0025] The adjusting assembly 3 includes a sliding sleeve 301. The sliding sleeve 301 is slidably inserted into the trapezoidal rod 2, and a scale 302 is provided on the circumferential outer wall of the sliding sleeve 301. The indicating block 5 is adapted to the scale 302.

[0026] Specifically, the bending machine body 1 includes a hydraulic cylinder 101, an arc-shaped top plate 102, a fixing plate 103, a rotating plate 104, and two supporting blocks 105. The arc-shaped top plate 102 is fixedly installed at the piston end of the hydraulic cylinder 101. The fixing plate 103 is fixedly installed on one side of the hydraulic cylinder 101. The rotating plate 104 is rotatably installed on one side of the hydraulic cylinder 101. The two supporting blocks 105 are movably arranged between the fixing plate 103 and the rotating plate 104. The trapezoidal rod 2 is fixedly installed at the bottom of the fixing plate 103. The indicating blocks 5 are respectively fixedly installed at both ends of the fixing plate 103.

[0027] In this implementation, during use, the pipe to be bent is placed between the two support blocks 105 and the arc-shaped top plate 102, and then the hydraulic cylinder 101 is started to make the arc-shaped top plate 102 approach the pipe and slightly clamp the pipe. After adjustment, the hydraulic cylinder 101 is started again to perform bending.

[0028] Specifically, the adjusting assembly 3 further includes a slider 304 and a sliding rod 305. A sliding hole 303 is formed in the circumferential outer wall of the sliding sleeve 301. The slider 304 is slidably installed in the sliding hole 303. The sliding rod 305 is slidably inserted into the sliding sleeve 301. An inclined groove 306 is formed in the circumferential outer wall of the sliding rod 305. The bottom of the slider 304 is inclined, and the bottom of the slider 304 is in contact with the inclined inner wall of the inclined groove 306.

[0029] Specifically, the holding assembly 4 includes an L-shaped plate 401 and a handle 402. The L-shaped plate 401 is fixedly installed on the circumferential outer wall of the sliding sleeve 301, and the handle 402 is fixedly installed at one end of the L-shaped plate 401.

[0030] Specifically, the adjusting assembly 3 further includes a pressing plate 308 and a spring 309. The pressing plate 308 is fixedly installed at one end of the sliding rod 305, and the spring 309 is fixedly installed between the pressing plate 308 and the sliding sleeve 301.

[0031] Specifically, the adjusting assembly 3 further includes a limiting block 307. The limiting block 307 is fixedly installed on the circumferential outer wall of the sliding sleeve 301. A limiting groove 6 is formed at the bottom of the trapezoidal rod 2, and the limiting block 307 is slidably installed in the limiting groove 6.

[0032] In this implementation, by providing the limiting block 307 and the limiting groove 6, the sliding sleeve 301 can be prevented from rotating when sliding in the trapezoidal rod 2.

[0033] Specifically, a strip-shaped groove 7 is formed in the inner wall of the trapezoidal rod 2. The strip-shaped groove 7 is adapted to the slider 304. The top inner wall of the strip-shaped groove 7 and the top of the slider 304 are both subjected to frosting treatment.

[0034] In this implementation, in the initial state, the top of the slider 304 is in contact with the top inner wall of the strip-shaped groove 7, having a large frictional force, which can prevent the sliding sleeve 301 from sliding during handling.

[0035] Working principle: In the initial state, the top of the slider 304 contacts the top inner wall of the strip groove 7, which has a large friction force, which can prevent the sliding sleeve 301 from sliding during transportation. When in use, the pipe to be bent is placed between the two support blocks 105 and the arc-shaped top plate 102, and then the hydraulic cylinder 101 is started to make the arc-shaped top plate 102 close to the pipe and slightly clamp the pipe without affecting the axial sliding. Then, hold the two handles 402 and press the two pressing plates 308 to push the two sliding rods 305 to slide close to each other. The two sliding rods 305 approaching each other will cause the two inclined grooves 306 to slide close to each other, and the two As the inclined groove 306 slides, the slider 304 will slide downward along the inclined inner wall of the inclined groove 306 and detach from the top inner wall of the strip groove 7. At this time, the two sliding sleeves 301 will not be affected by the friction between the slider 304 and the strip groove 7. At this time, slide the two handles 402 to make the two L-shaped plates 401 contact the two ends of the pipe respectively, and then observe the scales 302 indicated by the two indicator blocks 5 respectively. According to the difference between the two scales 302, the distance to be adjusted is determined, and then slide the two handles 402 to adjust the scales 302 indicated by the two indicator blocks 5 to be the same, so that the center of the pipe can be aligned with the piston end of the hydraulic cylinder 101.
