The heating tube generally needs to be bent, flattened and tested at the end in the final processing. For pipe bending, the commonly used pipe bending forming methods include bending, pushing, rolling and pressing. Although the bending processing of pipe fittings can be realized, it can only be bent into a single shape in one plane. Therefore, when two or more planes need to be formed into multiple bending angles, the bending machine of the prior art is difficult to achieve; and after the pipe is bent, the end face of the bent pipe needs to be cut to form the connection end of the center of the pipe fitting, and the cut end face needs to be flattened and tested.

[0045] The working principle of the present invention is: firstly, a plurality of processed pipes are placed in batches on the upper part of the inclined discharge plate 122, so that they are arranged and slide into the upper channel 136 along the inclined discharge plate 122, and the pipes are restricted to the lower end of the upper channel 136 by the limit column 1310. When bending is required, the outer guide plate 1312 is pulled outward by the opening and closing cylinder, so that the pipes in the upper channel 136 are freed from the restraint of the limit column 1310 and fall into the lower channel 137, and finally fall on the mobile bending component 16; when the sensor (infrared) senses that the pipes fall into the mobile bending component 16, After that, the center positioning cylinder 141 pushes the lower rack 142 or the upper rack 143 to move forward and backward under the action of the gear 144, so that the lower positioning guide rod 145 and the upper positioning guide rod 146 simultaneously drive the left positioning frame plate 147 and the right positioning frame plate 148 to move to both sides of the pipe, and fix the pipe through the left positioning groove 149 and the right positioning groove 1410. After the left positioning block and the right positioning block move to the same length of the pipe, the pipe is centrally positioned, and then the center positioning cylinder 141 pulls the lower rack 142 or the upper rack 143 in the opposite direction. The lower positioning guide rod 145 and the upper positioning guide rod 146 simultaneously drive the left positioning frame plate 147 and the right positioning frame plate 148 to return to their original positions; when bending afterwards, the mobile bending cylinder 165 first drives the mobile bending push block 166 to clamp the pipe between the mobile bending push block 166 and the mobile bending die holder 164, and then the mobile motor 161 and the mobile screw rod 162 drive the mobile plate and the mobile bending die holder 164 to move toward the bending wheel 154. At the same time, the two roller bending cylinders 151 drive the two bending wheels 154 to reasonably adjust the two bending wheels according to the length and position of the pipe bending. The moving motor 161 and the moving screw 162 then drive the moving plate and the moving bending die holder 164 to move forward, and cooperate with the two bending wheels 154 to initially bend the pipe into a V-shape; the moving motor 161 and the moving screw 162 then drive the moving plate, the moving bending die holder 164, and the pipe initially bent into a V-shape to move to a position corresponding to the clamping block 174, and then the two clamping cylinders 172 drive the two clamping blocks 174 to cooperate with the moving bending die holder 164 to perform a secondary bend inwards on the same plane on the middle portion of the pipe initially bent into a V-shape;Then, the two groups of clamping components are driven to move simultaneously by the conveying motor 182 and the conveying screw 183, and one of the two groups of clamping components moves to the rear of the moving plate. At the same time, the moving motor 161 and the moving screw 162 drive the moving plate, the moving bending die base 164 and the pipe after the secondary bending to move to the rear end to facilitate the clamping of the clamping components. Then, the clamping lifting cylinder 185 drives the clamping lifting seat, the clamping cylinder 186 and the two clamping blocks 187 to move downward, and then the clamping cylinder 186 drives the two clamping blocks 187 to clamp the rear end of the pipe after the secondary bending on the moving bending die base 164. Then, the conveying motor 182 and The conveying screw 183 drives the clamping assembly and the secondary bent pipe to move to the pressing assembly 19, and places the secondary bent pipe at the corresponding position on the pressing assembly 19. After the secondary bent pipe is moved and placed on the pressing template 196, the pressing cylinder 192 drives the pressing column 193 and the pressing plate 194 to press down the bent pipe after the secondary bending, so that its upper, lower, left and right positions are parallel and aligned, and a moving pressing push plate 2016 is connected.

Then, the end bending cylinder 208 drives the end bending rod 209 upward to swing downward, so that the end bending pipe 2011 is pressed down and fixed on the pipe extending out of the front end of the end bending die seat 207. Then, the end bending motor 2012 drives the end bending shaft 2013 and the end bending toothed disc 2014 to rotate, and drives the two semicircular gears 2015 to rotate, so that the middle part of the pipe rotates 90 degrees, so that the eccentric bending forming of the pipe end can be realized, and finally a completely formed bent pipe forming part is obtained;The longitudinal moving cylinder 211 drives the longitudinal moving frame 212, the lifting motor 213, the transverse moving frame 215, the transverse moving cylinder 216, the clamping cylinder and the two clamping blocks to move backward to the upper side corresponding to the formed elbow. Then the lifting motor 213 drives the transverse moving frame 215, the transverse moving cylinder 216, the clamping cylinder and the two clamping blocks to descend together. Then the transverse moving cylinder 216 drives the clamping cylinder and the two clamping blocks to move transversely.
