Description

Technical Field

[0001] This utility model relates to the field of cold working technology of pipes, and in particular to a pipe bending machine. Background Technology

[0002] Some existing straight metal pipes need to be bent into L-shaped pipes using a pipe bending machine. Existing pipe bending machines, as shown in patent application number CN86207856, include a bending die, a movable clamping block, and a fixed clamping block. The fixed clamping block is fixedly connected to one side of the bending die, opposite to the movable clamping block. During bending, the movable clamping block presses one end of the pipe against the fixed clamping block. The bending die, movable clamping block, and fixed clamping block rotate synchronously, bending the pipe. However, with existing pipe bending machines, the inner side of the pipe near the movable clamping block lacks support. During bending, the movable and fixed clamping blocks easily squeeze and deform the clamping end of the pipe. Furthermore, the pipe needs to be manually placed between the movable and fixed clamping blocks, which is labor-intensive and carries a risk of injury. Utility Model Content

[0003] In order to solve the above-mentioned defects of existing pipe bending machines, this utility model proposes a pipe bending machine in which the clamped end of the pipe is not easily squeezed and deformed, has a feeding function, and improves safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A pipe bending machine includes a main body, which includes a bending die, a fixed clamping block fixedly connected to one side of the bending die, and a movable clamping block opposite to the fixed clamping block. A clamping space for clamping pipes is formed between the fixed clamping block and the movable clamping block. The bending mechanism also includes a feeding mechanism that can rotate synchronously with the bending die, the fixed clamping block, and the movable clamping block. The feeding mechanism includes a support plate, a support head, a first pushing cylinder, and a second pushing cylinder. A positioning surface adapted to the pipe to be bent is provided on one side of the support plate. The first pushing cylinder faces the positioning surface and pushes the pipe to the positioning surface so that the end of the pipe is aligned with the clamping space. The second pushing cylinder is aligned with the rear end of the pipe. The support head is installed at the front end of the second pushing cylinder. The outer diameter of the front end of the support head is adapted to the inner diameter of the pipe. A boss is provided on the outer side of the middle part of the support head. The front-to-back distance between the front end of the support head and the boss is less than or equal to the front-to-back distance of the clamping space.

[0005] With the above settings, firstly, when the pipe bending machine bends the pipe, the front end of the support head can support the clamped end of the pipe, thereby preventing the clamped end of the pipe from being deformed by pressure. Secondly, the feeding mechanism of the pipe bending machine can replace manual labor to push the pipe between the fixed clamping block and the movable clamping block, thus improving safety.

[0006] Furthermore, the feeding mechanism also includes a pipe box, which is fixedly connected to the upper side of the support plate. The pipe box is provided with a storage space for stacking individual pipes. A pipe outlet is provided on the lower end of the pipe box near the positioning surface, and an avoidance opening is provided on the side of the pipe box away from the pipe outlet. The first pipe pusher cylinder pushes the pipe to the positioning surface through the pipe outlet.

[0007] With the above setup, the pipe box can hold the pipe to be bent, allowing the first pipe-pushing cylinder to continuously feed the pipe to the positioning surface, further reducing manual labor.

[0008] Furthermore, the support plate has a slope at the bottom of the tube box, with the side of the slope away from the positioning surface tilting downwards.

[0009] With the above setup, the placed pipe will roll automatically through the outlet to the positioning surface after it is lowered.

[0010] Furthermore, the feeding mechanism also includes a buffer head, which includes a push tube, a guide rod, a first elastic element, and a slider. The slider is fixedly connected to the output shaft of the first push tube cylinder. The push tube passes through the clearance opening and faces the tube. One end of the guide rod is fixedly connected to the push tube, and the other end passes through the slider and is slidably connected to the slider. The first elastic element is installed between the slider and the push tube.

[0011] The above settings reduce the impact force of the first push cylinder on the pipe, thus preventing pipe deformation.

[0012] Furthermore, the pusher tube includes a vertical part and a horizontal part. The width of the horizontal part is greater than the width of the tube box. The horizontal part is horizontally positioned above the slider and extends into the clearance opening. The vertical part is vertically fixedly connected to the lower side of the horizontal part near the tube. One end of the guide rod is fixedly connected to the vertical part.

[0013] With the above settings, the upper side of the push pipe is flat, reducing wear on the pipes in the pipe box.

[0014] Furthermore, a sliding groove is provided at the rear end of the support head, and the output shaft of the second push cylinder is slidably connected in the sliding groove. A second elastic element is installed between the output shaft of the second push cylinder and the bottom of the sliding groove.

[0015] The above settings achieve two objectives: first, to reduce the impact of the support head on the rear end of the pipe; and second, to ensure that the boss of the support head contacts the rear end of the pipe, thereby improving the bending accuracy.

[0016] Furthermore, the main body of the pipe bending machine also includes a movable seat, a first linear driver, a fixed seat, and a rotating mechanism. The movable seat is rotatably connected to the upper side of the fixed seat and is driven by the rotating mechanism. The pipe bending die and the first linear driver are both fixedly connected to the upper side of the movable seat. The first linear driver is used to drive the movable clamping block to move closer to or away from the fixed clamping block. The feeding mechanism is also set on the movable seat.

[0017] Furthermore, the main body of the pipe bending machine also includes an anti-rotation mechanism, which includes a support block, a second linear drive, and a third linear drive. The support block is parallel to the pipe and is located in front of the movable clamping block. The second linear drive is used to drive the support block to move left and right, and the third linear drive is used to drive the support block to move back and forth.

[0018] With the above setup, the anti-rotation mechanism supports the pipe, and when the clamped end of the pipe rotates, the other end does not rotate, thus completing the pipe bending.

[0019] Furthermore, the pipe bending machine also includes a discharge mechanism, which includes a motor, a connecting rod, and a support plate. The motor is located on the side of the pipe bending die away from the feeding mechanism and is fixedly connected to the upper side of the fixed base. The support plate is horizontally located on the lower side of the pipe bending die to receive the bent pipe. The support plate is connected to the motor through the connecting rod.

[0020] The above settings facilitate material discharge from the pipe bending machine. Attached Figure Description

[0029] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0030] like Figures 1 to 8A pipe bending machine includes a main body, which includes a bending die 3, a fixed clamping block 4 fixedly connected to one side of the bending die 3, and a movable clamping block 5 opposite to the fixed clamping block 4. A clamping space 6 for clamping pipes is formed between the fixed clamping block 4 and the movable clamping block 5. The bending mechanism also includes a feeding mechanism that can rotate synchronously with the bending die 3, the fixed clamping block 4, and the movable clamping block 5. The feeding mechanism includes a support plate 7, a support head 8, a first pipe pushing cylinder 9, and a second pipe pushing cylinder 10. One side of the support plate 7... A positioning surface 111 adapted to the pipe 11 to be bent is provided. The first push cylinder 9 faces the positioning surface 111 and pushes the pipe to the positioning surface 111 so that the end of the pipe is aligned with the clamping space 6. The second push cylinder 10 is aligned with the rear end of the pipe. The support head 8 is installed at the front end of the second push cylinder 10. The outer diameter of the front end of the support head 8 is adapted to the inner diameter of the pipe. A boss 12 is provided on the outer side of the middle part of the support head 8. The front-to-back distance between the front end of the support head 8 and the boss 12 is less than or equal to the front-to-back distance of the clamping space 6.

[0031] With the above settings, firstly, when the pipe bending machine bends the pipe, the front end of the support head 8 can support the clamped end of the pipe, thereby preventing the clamped end of the pipe from being deformed by pressure. Secondly, the feeding mechanism of the pipe bending machine can replace manual labor to push the pipe between the fixed clamping block 4 and the movable clamping block 5, thereby improving safety.

[0032] One side of the bending die 3 in this application is arc-shaped, with a radius adapted to the bending radius of the pipe. The arc-shaped surface of the bending die 3 is provided with a groove adapted to the outer diameter of the pipe to prevent the pipe from moving up and down during bending. The fixing block 4 is locked to one end of the arc-shaped surface of the bending die 3 by fasteners. Figure 1 The directions of the pipe bending machine are marked in the middle for ease of description. The movable clamping block 5 is located to the right of the fixed clamping block 4 and can move left and right under power. Both the right side of the fixed clamping block 4 and the left side of the movable clamping block 5 are provided with arc-shaped grooves adapted to the outer diameter of the pipe to increase the contact area with the pipe and improve the clamping effect. The support plate 7 is horizontally located behind the fixed clamping block 4 and the movable clamping block 5. The left side of the support plate 7 is provided with the aforementioned positioning surface 111. The cross-section of the positioning surface 111 is arc-shaped and adapted to the outer diameter of the pipe. The positioning surface 111 extends in the front-back direction. When the first pipe pushing cylinder 9 pushes the pipe to the positioning surface 111, the left side of the pipe is in contact with the left side of the positioning surface 111, and the pipe extends in the front-back direction with the front end of the pipe facing the fixed clamping block 4 and the movable clamping block 5. The second pipe pushing cylinder 10 drives the support head 8 to move forward, and the front end of the support head 8 is inserted into the rear end of the pipe. Figure 5To increase the success rate of inserting the pipe into the front end of the support head 8, a chamfer can be set at the front end of the support head 8. When the outer boss 12 of the support head 8 abuts against the rear end of the pipe, the first push cylinder 9 retracts and releases the pipe, and the second push cylinder 10 continues to drive the support head 8 forward until the rear end of the pipe moves between the fixed clamping block 4 and the movable clamping block 5, that is, until the rear end of the pipe moves into the clamping space 6. At this time, the left side of the rear end of the pipe is basically against the right side of the fixed clamping block 4. That is, when the second push cylinder 10 pushes the pipe forward, the pipe basically moves forward against the right side of the fixed clamping block 4. To prevent the front end of the pipe from interfering with the fixed clamping block 4, a chamfer can be processed on the rear end of the right side of the fixed clamping block 4. When the movable clamping block 5 approaches the fixed clamping block 4 and clamps the pipe, the rear end of the pipe will not move left or right, preventing the output shaft of the second push cylinder 10 from moving left or right and being damaged. Figure 7 Since the front-to-back distance from the front end of the support head 8 to the boss 12 is less than or equal to the front-to-back distance of the clamping space 6, that is, when the movable clamping block 5 and the fixed clamping block 4 clamp the rear end of the pipe, the front end of the support head 8 will not protrude from the front side of the movable clamping block 5 and the fixed clamping block 4. The bending die 3, the fixed clamping block 4, the movable clamping block 5 and the feeding mechanism rotate synchronously around the axis of the bending die 3. The fixed clamping block 4 and the movable clamping block 5 clamp the rear end of the pipe and bend the pipe. Figure 8 After bending, the second push cylinder 10 retracts, the support head 8 is pulled out from the rear end of the pipe, the movable clamp 5 moves away from the fixed clamp 4, the pipe is released and falls, and the discharge is completed.

[0033] As one implementation method, the feeding mechanism also includes a tube box 13, which is fixedly connected to the upper side of the support plate 7. The tube box 13 is provided with a storage space for stacking individual tubes. The lower end of the tube box 13 is provided with a tube outlet 14 on the side close to the positioning surface 111, and a clearance opening 15 is provided on the side of the tube box 13 away from the tube outlet 14. The first tube pusher cylinder 9 pushes the tube to the positioning surface 111 through the tube outlet 14.

[0034] With the above setup, the pipe box 13 can store the pipe to be bent, so that the first pipe pusher 9 can continuously deliver the pipe to the positioning surface 111, further reducing manual labor.

[0035] The pipe box 13 of this application has a front-to-back length that matches the length of the pipe and a left-to-right width that matches the outer diameter of the pipe. Multiple pipes extending in the front-to-back direction are placed in the pipe box 13, with one pipe per layer. The outlet 14 at the bottom of the pipe box 13 matches the shape of the pipe, and only one pipe can be output at a time. When the first pusher cylinder 9 pushes the pipe, the output shaft extends into the pipe box 13 through the clearance port 15, pushing the bottommost pipe to the positioning surface 111 through the outlet 14. After the output shaft of the first pusher cylinder 9 retracts, the pipe in the pipe box 13 automatically falls down so that the first pusher cylinder 9 can push it again. The upper side of the pipe box 13 is open to facilitate manual replenishment of pipes.

[0036] As one implementation, the support plate 7 has an inclined surface 16 at the bottom of the tube box 13, and the side of the inclined surface 16 away from the positioning surface 111 is inclined downward.

[0037] With the above settings, after the pipe is placed and lowered, it will roll automatically through the outlet 14 to the positioning surface 111.

[0038] Specifically, each time the first pusher cylinder 9 pushes out a tube and retracts, the tube in the tube box 13 moves downward under the action of gravity. After the new tube comes into contact with the inclined surface 16, it will not move towards the outlet 14, so that the tube is stably stored in the tube box 13. The tube can only be pushed to the positioning surface 111 by the first pusher cylinder 9.

[0039] As one implementation, the feeding mechanism also includes a buffer head 17, which includes a push tube 171, a guide rod 172, a first elastic element 173, and a slider 174. The slider 174 is fixedly connected to the output shaft of the first push tube cylinder 9. The push tube 171 passes through the clearance port 15 and faces the tube. One end of the guide rod 172 is fixedly connected to the push tube 171, and the other end passes through the slider 174 and is slidably connected to the slider 174. The first elastic element 173 is installed between the slider 174 and the push tube 171.

[0040] The above settings reduce the impact force of the first push cylinder 9 on the pipe, thus preventing pipe deformation.

[0041] When the first pusher cylinder 9 extends, the pusher 171 of the buffer head 17 pushes the tube towards the positioning surface 111. After the tube contacts the positioning surface 111, the first pusher cylinder 9 continues to extend, the guide rod 172 slides relative to the slider 174, and the first elastic element 173 contracts and deforms, playing a buffering role. Figure 4 The guide rod 172 is parallel to the first push cylinder 9, and the guide rod 172 increases the stability of the movement of the push tube 171.

[0042] As one implementation, the pusher pipe 171 includes a vertical part 1711 and a horizontal part 1712. The width of the horizontal part 1712 is greater than the width of the pipe box 13. The horizontal part 1712 is horizontally arranged above the slider 174 and extends into the clearance opening 15. The vertical part 1711 is vertically fixedly connected to the lower side of the horizontal part 1712 near the pipe. One end of the guide rod 172 is fixedly connected to the vertical part 1711.

[0043] With the above settings, the upper side of the push pipe 171 is flat, reducing wear on the pipes in the pipe box 13.

[0044] When the pusher pipe 171 of this application pushes the pipe, the remaining pipe in the pipe box 13 will contact the horizontal part 1712 of the pusher pipe 171. The upper side of the horizontal part 1712 is flat to reduce wear on the pipe.

[0045] As one implementation, a groove 18 is provided at the rear end of the support head 8, the output shaft of the second push cylinder 10 is slidably connected in the groove 18, and a second elastic element 19 is installed between the output shaft of the second push cylinder 10 and the bottom of the groove 18.

[0046] With the above settings, firstly, the impact of the support head 8 on the rear end of the pipe is reduced; secondly, the protrusion 12 of the support head 8 is ensured to contact the rear end of the pipe, thereby improving the bending accuracy.

[0047] The support head 8 of this application moves forward under the action of the second push cylinder 10. The front end of the support head 8 is inserted into the rear end of the pipe. At this time, the push cylinder 9 pushes the pipe 171 to press the pipe onto the positioning surface 111. The pipe will not move back and forth. The support head 8 continues to move forward. After the boss 12 on the outside of the support head 8 contacts the rear end of the pipe, the second push cylinder 10 continues to extend. The second elastic element 19 contracts and deforms to ensure that the boss 12 contacts the rear end of the pipe. After the first push cylinder 9 releases the pipe, the second push cylinder 10 continues to extend, driving the pipe to move forward. The second push cylinder 10 can be a servo electric cylinder to improve its extension and retraction accuracy and ensure that after the pipe moves forward, the rear end of the pipe moves between the fixed clamping block 4 and the movable clamping block 5.

[0048] As one implementation, the main body of the pipe bending machine also includes a movable seat 20, a first linear driver 21, a fixed seat 22, and a rotating mechanism 23. The movable seat 20 is rotatably connected to the upper side of the fixed seat 22 and is driven by the rotating mechanism 23. The pipe bending die 3 and the first linear driver 21 are both fixedly connected to the upper side of the movable seat 20. The first linear driver 21 is used to drive the movable clamping block 5 to move closer to or away from the fixed clamping block 4. The feeding mechanism is also set on the movable seat 20.

[0049] Specifically, the rotating mechanism 23 adopts a servo system, which can precisely control the rotation angle of the movable seat 20. The rotation center of the bending mold 3 coincides with the rotation center of the movable seat 20. The bending mold 3 is fixedly connected to the upper side of the movable seat 20. The support plate 7 is horizontally fixedly connected above the movable seat 20. The first linear driver 21 can be an electric push rod, and its output end is connected to the movable clamping block 5. When the movable seat 20 rotates, the bending mold 3, the fixed clamping block 4 and the movable clamping block 5 rotate synchronously around the rotation center of the bending mold 3 to complete the bending.

[0050] As one implementation method, the main body of the pipe bending machine also includes an anti-rotation mechanism, which includes a support block 24, a second linear driver 25 and a third linear driver 26. The support block 24 is parallel to the pipe and is set in front of the movable clamping block 5. The second linear driver 25 is used to drive the support block 24 to move left and right, and the third linear driver 26 is used to drive the support block 24 to move back and forth.

[0051] With the above setup, the anti-rotation mechanism supports the pipe, and when the clamped end of the pipe rotates, the other end does not rotate, thus completing the pipe bending.

[0052] Both the second linear actuator 25 and the third linear actuator 26 of this application can be electric actuators. The second linear actuator 25 extends in the left-right direction, and the third linear actuator 26 extends in the front-back direction. Specifically, a transition seat 27 is slidably connected to the upper side of the fixed base 22 in the left-right direction and is driven by the second linear actuator 25 fixedly connected to the fixed base 22. The support block 24 is slidably connected to the upper side of the transition seat 27 in the front-back direction and is driven by the third linear actuator 26 fixedly connected to the upper side of the transition seat 27. Figure 5 Initially, both the support block 24 and the movable clamping block 5 are far from the fixed clamping block 4, facilitating the forward movement of the pipe. When the rear end of the pipe moves between the fixed clamping block 4 and the movable clamping block 5, the first linear actuator 21 and the second linear actuator 25 operate, the movable clamping block 5 clamps the rear end of the pipe, and the support block 24 supports the side of the pipe. Figure 7 When the bending mold 3 rotates, as... Figure 8 As the movable clamping block 5 and the bending die 3 rotate, the third linear actuator 26 drives the support block 24, which moves backward to provide support for the pipe at the bending point, thereby improving the bending quality of the pipe.

[0053] As one implementation method, the pipe bending machine also includes a discharge mechanism, which includes a motor 28, a connecting rod 29 and a support plate 30. The motor 28 is located on the side of the pipe bending mold 3 away from the feeding mechanism and is fixedly connected to the upper side of the fixed base 22. The support plate 30 is horizontally located on the lower side of the pipe bending mold 3 and is used to receive the bent pipe. The support plate 30 is connected to the motor 28 through the connecting rod 29.

[0054] The above settings facilitate material discharge from the pipe bending machine.

[0055] Specifically, the pallet 30 is basically a fan-shaped structure, set under the bending mold 3, so that the final product can fall onto the pallet 30, such as... Figure 8 After the movable seat 20 rotates clockwise and the pipe is bent, the support head 8 is pulled out from the end of the pipe. After the movable clamp 5 releases the pipe, the pipe falls from the bending mold 3 onto the support plate 30. After the movable seat 20 rotates counterclockwise back to the initial position, the motor 28 drives the support plate 30 to rotate clockwise through the connecting rod 29, which takes the bent pipe on the support plate 30 away from the bending mold 3. After the material is discharged, the motor 28 drives the support plate 30 to rotate counterclockwise to the underside of the bending mold 3.

[0056] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
