Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical manufacturing and automation field especially relates to a full -automatic pipe bender. BACKGROUND

[0002] Steel pipe as an important industrial material, is widely used in building, machinery, automobile, petroleum chemical industry etc. field. Steel pipe's bending processing is one of the key steps in the manufacturing process, and through bending, steel pipe can adapt to different structure demand. Steel pipe's bending usually is completed through mechanical equipment, and common bending mode includes cold bending and hot bending. Cold bending is through mechanical force to make steel pipe plastic deformation at normal temperature, and hot bending is through heating to make steel pipe soften and then bend. Whether it is cold bending or hot bending, the bending process of steel pipe needs accurate control to ensure that the bending angle and shape meet the design requirements.

[0003] The existing steel pipe bending equipment usually includes clamp, runner and stabilizer block etc. component. Staff first puts steel pipe into the equipment, then pushes steel pipe to make it pass through clamp completely. Subsequently, clamp and stabilizer block move together, clamp takes another side of steel pipe and fixes it on runner. After clamp fixing, staff releases steel pipe, clamp follows runner rotation, and stabilizer block keeps steel pipe close to runner, thereby completing bending process. This equipment can meet the bending demand of steel pipe to a certain extent, but its operation process has certain limitation.

[0004] The main defect of the existing steel pipe bending equipment is that it needs manual assistance in the operation process. When clamping steel pipe, staff needs to manually fix steel pipe to ensure that it does not slide or deviate in the bending process. In addition, when changing material, staff needs to carry out feeding operation immediately after discharging, and this continuous operation not only increases labor intensity, but also has certain safety hazard.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the utility model will be described in detail below with reference to the drawings. The person skilled in the art will appreciate that these descriptions are only descriptive, exemplary and should not be interpreted as limiting the protection scope of the utility model.

[0022] It should be noted that: similar signs represent similar items in the following drawings, therefore, once an item is defined in one drawing, it can not be further defined and explained in the subsequent drawings.

[0023] This embodiment mainly describes the structure of the pipe bending machine, as follows:

[0024] A fully automatic pipe bending machine, such as Figures 1-4 As shown, the device includes a pipe bending machine 1, a base 2, a feeding rack 3, a feeding rack 4, a storage rack 5, a motor 6, a lead screw 7, a push plate 8, and a baffle 81. The pipe bending machine 1 has a bending disc, two electric push rods, and a clamp, which can automatically complete the bending process of the steel pipe. The base 2 is located in the feeding direction of the pipe bending machine 1, and the feeding rack 3 is connected to the base 2. The storage rack 5 is installed on the feeding rack 3. An opening is provided between the bottom of the storage rack 5 and the feeding rack 3. The height of the opening is slightly larger than the diameter of the pipe to ensure that the steel pipe can be smoothly discharged. The storage rack 5 is open, and the upper side of the unloading rack 3 is inclined. The steel pipe rolls along the inclined surface. The rear end of the unloading rack 3 is connected to the feeding rack 4. The right end of the feeding rack 4 is equipped with a motor 6. The middle of the feeding rack 4 is rotatably connected to a lead screw 7. The output shaft of the motor 6 is connected to the lead screw 7. The push plate 8 is threadedly connected to the lead screw 7. The push plate 8 is slidably connected to the feeding rack 4, and the right side of the push plate 8 is connected to a baffle 81. The length of the baffle 81 is greater than the width of the unloading rack 3 to ensure that the next steel pipe will not fall onto the feeding rack 4 and affect the reset of the push plate 8.

[0025] like Figure 3 As shown, it also includes a limiting plate 9, an adjusting screw 10, and a guide rod 11. The limiting plate 9 is slidably connected to the right side of the unloading rack 3. The guide rod 11 is slidably connected to the right side plate of the unloading rack 3. The left end of the guide rod 11 is connected to the rear of the limiting plate 9. The front end of the limiting plate 9 is located inside the storage rack 5. The adjusting screw 10 is rotatably connected to the right side of the storage rack 5. The left end of the adjusting screw 10 is rotatably connected to the limiting plate 9.

[0026] like Figure 4 As shown, it also includes an operating lever 13. The adjusting screw 10 has a movable cavity 12. The operating lever 13 is slidably connected in the movable cavity 12 of the adjusting screw 10. The operating lever 13 is provided with a spline to limit the relative rotation of the operating lever 13 and the adjusting screw 10. When the adjustment distance is long and the adjusting screw 10 is close to the storage rack 5, the operating lever 13 can be pulled out, which makes it easier for the staff to apply force and makes the adjustment process more convenient, while ensuring the accuracy and stability of the adjustment.

[0027] like Figure 3 As shown, it also includes a magnet 14. A magnet 14 is provided on the front side of the feeding rack 4. The attraction force of the magnet 14 ensures that the steel pipe maintains a stable position during the feeding process and reduces feeding errors.

[0028] like Figure 2 As shown, it also includes rollers 15. Several rollers 15 are rotatably connected to the bottom of the inclined surface of the feeding frame 3. The rotation of the rollers 15 makes the steel pipe feed more smoothly, reduces the feeding resistance, and reduces the wear on the surface of the steel pipe.

[0029] As Figure 3 shown, it also includes a telescopic pad 16, which is arranged between the limiting plate 9 and the right side plate of the unloading rack 3, and is used to block sundries and prevent them from falling into the gap between the limiting plate 9 and the unloading rack 3. The elastic design of the telescopic pad 16 enables it to adapt to the movement of the limiting plate 9, ensuring smooth movement of the limiting plate 9.

[0030] As Figure 2 shown, it also includes a protective pad 17, which is connected to the left side of the push plate 8 and serves as a buffer when the push plate 8 pushes the steel pipe, reducing the direct impact between the push plate 8 and the steel pipe. The soft material of the protective pad 17 can effectively absorb the impact force, protecting the surface of the steel pipe from damage and prolonging the service life of the push plate 8.

[0031] As Figure 1 shown, it also includes a scale 18, which is connected to the top of the front side of the limiting plate 9 and faces the right side. By observing the readings of the scale 18, the position of the limiting plate 9 can be accurately adjusted to ensure that the width of the steel pipe placed meets the requirements.

[0032] The staff places the straight steel pipe into the storage rack 5, and the steel pipe falls from the opening between the storage rack 5 and the unloading rack 3 due to gravity. The opening height is slightly larger than the diameter of the steel pipe to ensure smooth passage. The steel pipe rolls along the slope of the unloading rack 3 and finally contacts the feeding rack 4. The magnet 14 arranged on the front side of the feeding rack 4 generates a magnetic attraction force on the steel pipe, preventing it from producing reverse displacement due to impact with the feeding rack 4. Then, the motor 6 starts to drive the screw rod 7 to rotate, which in turn drives the push plate 8 to move towards the pipe bender 1, and the push plate 8 pushes the steel pipe to complete the feeding. The protective pad 17 on the left side of the push plate 8 serves as a buffer when it contacts the steel pipe. After the steel pipe enters the pipe bender 1, the pipe bender 1 automatically completes the bending work. After bending is completed, the motor 6 reverses, and the push plate 8 resets. During the movement of the push plate 8, the baffle 81 moves synchronously with the push plate 8, blocking other steel pipes on the unloading rack 3 from falling down, ensuring the safety of the push plate 8 movement path. The roller 15 arranged at the bottom of the slope of the unloading rack 3 contacts the bottom of the steel pipe, reducing the sliding friction between the steel pipe and the feeding rack 4, making the feeding process smoother.

[0033] For different length of steel pipe, the staff turns the adjusting screw 10 through the operating rod 13, the adjusting screw 10 moves along the storage rack 5 and pushes the limiting plate 9 to move synchronously, so as to adjust the placing width of the steel pipe in the storage rack 5. The movement of the limiting plate 9 ensures that the steel pipe can only fall vertically, avoiding the influence of inclination on blanking. The front end of the limiting plate 9 extends into the storage rack 5, and the rear end is slidingly connected with the blanking rack 3 through the guide rod 11, which ensures the stability and consistency of the movement of the limiting plate 9. The expansion pad 16 arranged between the limiting plate 9 and the right side plate of the blanking rack 3 prevents sundries from falling into the gap and ensures the smooth movement of the limiting plate 9. The scale 18 connected to the top of the limiting plate 9 shows the current adjusted distance, which facilitates the staff to accurately control the placing position of the steel pipe.
