[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0020] like Figure 1-Figure 3 As shown, this example provides a pipe continuous bending device, including: a workbench 100, a limiting assembly 200, and a bending assembly 300.
[0021] A stop rod 101 is provided on one side of the workbench 100 in the length direction, and a plurality of through slots 102 are provided on the other side along the length direction, and the length direction of the through slots 102 is parallel to the width direction of the workbench 100; the limiting assembly 200 includes two rows of positioning rods 201 which are respectively arranged on both sides of the length direction of the workbench 100 and move along the vertical direction, one row of positioning rods 201 is respectively passed through the through slots 102 and moves along the length direction, and a pressure plate 202 is also provided on the outside of the stop rod 101 for positioning the bending part of the pipe; the bending assembly 300 includes two moving blocks 301 which are respectively arranged on both sides of the length direction of the workbench 100 and move along the length and width directions, a plurality of pressure wheels 302 are provided on the moving blocks 301, and two pressure rods 303 which move along the width direction of the workbench 100 are also provided between the two moving blocks 301 for bending the pipe.
[0022] Specifically, in order to facilitate the positioning of the pipe when the pipe is bent for the first time, a positioning plate 103 is provided at one end of the workbench 100 close to the baffle 101, and the positioning plate 103 is sleeved on two slide bars 104. The slide bar 104 is installed at one end of the workbench 100, and a baffle 105 is provided at the other end of the slide bar 104. One of the slide bars 104 is also sleeved with a first spring 106, and the two ends of the first spring 106 are respectively abutted against the baffle 105 and the positioning plate 103, and are always in a compressed state. It has a thread and is sleeved with a nut, which abuts against the other side of the positioning plate 103. The distance between the positioning plate 103 and the action platform 100 can be adjusted according to the length of the pipe that needs to be bent. At this time, the nut can be turned to move the positioning plate 103, and then one end of the pipe is abutted against the positioning plate 103. The pipe is bent by moving the pressure rod 303. At this time, the end of the pipe will push the positioning plate 103, and the first spring 106 is further compressed, thereby avoiding the fixation of the positioning plate 103 and affecting the normal bending of the pipe.
[0023] Specifically, when the pipe is bent for the first time, in order to avoid the movement of the pipe caused by the interaction between the positioning plate 103 and the end of the pipe, the pressing plate 202 is connected to the movable end of the first telescopic rod 203. The first telescopic rod 203 is installed on the workbench 100 and arranged along its width direction. The pressing plate 202 is driven to move by the first telescopic rod 203, so that the pressing plate 202 and the blocking rod 101 clamp the pipe to prevent the pipe from moving.
[0024] Specifically, the lower end of the positioning rod 201 is sequentially penetrated on the partition 204 and the support frame 205, and the support frame 205 located directly below the through slot 102 is connected to the moving end of the second horizontal linear mechanism. The second horizontal linear mechanism is installed below the workbench 100 and arranged along its width direction. When the position of the positioning rod 201 needs to be adjusted, the support frame 205 can be driven to move by the second horizontal linear mechanism. The movement of the support frame 205 will drive the positioning rod 201 to move together, and the other support frame 205 is installed on the bottom surface of the workbench 100, and a stop is provided on the positioning rod 201. Ring 206, a second spring 207 is also sleeved on the positioning rod 201, and the two ends of the second spring 207 are respectively abutted against the retaining ring 206 and the partition 204, and are always in a compressed state. Under the action of the second spring 207, the positioning rod 201 always has a tendency to move downward. When the pipe is bent, part of the positioning rod 201 is lower than the top surface of the workbench 100 due to the elastic force of the second spring 207 to avoid blocking the normal bending of the pipe. The positioning rod 201 that needs to position the pipe can have its upper end higher than the top surface of the workbench 100 under the action of external force.
[0025] Specifically, in order to facilitate the lifting of the positioning rods 201 in sequence, a top block 208 with a trapezoidal cross section is further provided under the support frame 205, and protrusions 209 are provided on both sides of the top block 208, and the protrusions 209 are slidably matched on the support frame 205. A convex rod 210 is provided on the bottom surface of the top block 208, one of the convex rods 210 is penetrated on the moving plate 211, and the moving plate 211 is provided with a long hole 212 along its length direction, and another convex rod 210 located directly below the through slot 102 is penetrated in the long hole 212, and the moving plate 211 is connected to the third horizontal linear mechanism. At the moving end, the third horizontal linear mechanism is installed under the workbench 100 and arranged along its length direction. The lower end of the positioning rod 201 is provided with an arc block 213. When the first bending is performed by the pressure rod 303, the two top blocks 208 are not in contact with the arc block 213. At this time, the upper ends of all the positioning rods 201 are lower than the top surface of the workbench 100. The two pressure rods 303 are moved simultaneously to bend the pipe into two parallel structures. When the second bending is performed, the axis of one of the pressure rods 303 is used as the bending point, and the pressure wheel 302 is moved to realize the alignment. The second bending of the pipe, and during the second bending, the upper end of the positioning rod 201 is also lower than the top surface of the workbench 100. After the second bending is completed, the movable plate 211 can be driven by the third horizontal linear mechanism to move along the length direction of the workbench 100, and the top block 208 will also move synchronously. As the arc block 213 contacts the top block 208, and the other top block 208 has not yet contacted the arc block 213, at this time, only one positioning rod 201 is higher than the top surface of the workbench 100, and the top block 208 will force the positioning rod 201 When the arc block 213 moves upward, the second spring 207 is further compressed. When the arc block 213 contacts the top surface of the top block 208, the positioning rod 201 is pushed to the highest position. At this time, the tube can be bent by moving the pressure wheel 302. After this bending, the top block 208 continues to move, and the top block 208 in contact with the arc block 213 gradually loses contact, while the other top block 208 contacts the corresponding arc block 213 and lifts the positioning rod 213. At this time, the tube can be bent again by the pressure wheel 302 on the other moving block 301.
[0026] Specifically, two slide grooves 107 whose length directions are parallel to their width directions are provided at one end of the workbench 100. The slide grooves 107 are respectively located on both sides of the blocking rod 101. The pressure rod 303 is passed through the slide groove 107, and the lower end is installed on the support block 304. The support block 304 is connected to the moving end of the first horizontal linear mechanism. The first horizontal linear mechanism is installed under the workbench 100. The pressure rod 303 is driven to move from one end of the slide groove 107 to the other end through the first horizontal linear mechanism to complete the first bending of the pipe.
[0027] Specifically, the moving block 301 is connected to the moving end of the second telescopic rod 305, the second telescopic rod 305 is connected to the moving end of the fourth horizontal linear mechanism, and the fourth horizontal linear mechanism is installed on the workbench 100. When the pipe is subsequently bent, the moving block 301 is driven by the fourth horizontal linear mechanism to move along the length direction of the workbench 100. At this time, the pressure wheel 302 will bend the pipe 90 degrees, and then the second telescopic rod 305 drives the moving block 301 to move along the width direction of the workbench 100, and the pipe will be bent 180 degrees. This cycle is repeated to achieve continuous bending of the pipe.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
