Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pipe bending equipment, and particularly relates to a pipe bending machine for shipbuilding. BACKGROUND

[0002] The pipe bending machine is commonly used for engineering construction, large equipment installation and configuration and the like, and is used for bending a steel pipe into a required shape or state so as to meet the actual requirements of a construction site and facilitate construction operation. In shipbuilding operation, due to the limited space of a ship body, a large space utilization rate is pursued in design, and a corresponding complex pipeline is designed according to the shape and structure of the ship body in the design of a ship body pipeline system. The pipeline used for installation is made to meet the design requirements and reach the functional and safety standards by using the pipe bending machine. The side of the steel pipe needs to be supported and driven to displace when the steel pipe is bent, so as to prevent breakage. The pushing mechanism of the current pipe bending machine can only control the tail of the steel pipe in actual operation, so that the side of the steel pipe can only obtain one-way support. When the pushing mechanism is far away, the supporting effect is poor. When the tail of the steel pipe needs to be bent, it is inconvenient to support the tail of the steel pipe, so that the bending of the tail of the steel pipe often needs to be handled separately, and it is inconvenient to bend a large number of steel pipes.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1 to 4 The utility model provides technical schemes as follows: A bent pipe machine for shipbuilding, comprising a body 1, a push mechanism 2, a bent pipe mechanism 3 and an auxiliary clamping mechanism 4 for assisting clamping and supporting the steel pipe 6; the push mechanism 2 is bolted to the rear end of the body 1, the bent pipe mechanism 3 is bolted to the side of the body 1, and the auxiliary clamping mechanism 4 is slidingly connected to the upper end of the body 1; two groups of sector teeth 5 are arranged in the auxiliary clamping mechanism 4, the sector teeth 5 are rotated when the auxiliary clamping mechanism 4 moves, and then the auxiliary clamping mechanism 4 drives the steel pipe 6 to be clamped from three directions, so that the steel pipe 6 can be supported when it is bent to the tail, the push mechanism 2 pushes the steel pipe 6 into the bent pipe mold 355, and the bent pipe mechanism 3 drives the steel pipe 6 to bend through rotation.

[0020] Please refer to Figure 3 A slot 11 is formed in the upper end of the body 1, and the auxiliary clamping mechanism 4 is slidingly connected to the upper end of the body 1 through the slot 11.

[0021] As another embodiment, as shown in Figures 1 to 3 The push mechanism 2 comprises a first sliding rail 22, an electric sliding arm 23 and a limiting tube 24; the lower end of the first sliding rail 22 is bolted to the upper end of the body 1, the lower end of the electric sliding arm 23 is slidingly connected to the first sliding rail 22, the rear end of the limiting tube 24 is bolted to the electric sliding arm 23, and the limiting tube 24 is inserted with the steel pipe 6.

[0022] In use, the electric sliding arm 23 is displaced along the direction of the first sliding rail 22, driving the displacement of the limiting tube 24, so that the limiting tube 24 is located at the rear end of the pipe bending mechanism 3, which is more convenient for the operator to align the steel pipe 6 with the pipe opening of the limiting tube 24. After the steel pipe 6 is inserted into the limiting tube 24, the electric sliding arm 23 is reversely displaced, driving the limiting tube 24 to return to the initial position, preparing for pipe bending operation. The electric sliding arm 23 can be driven by a motor-driven screw, and then drive the threaded sleeve structure, or other structures that can realize electric sliding. The present application does not limit here.

[0023] In the pipe bending operation, the electric sliding arm 23 is displaced along the direction of the first electric sliding rail, driving the horizontal displacement of the limiting tube 24, and then pushing the steel pipe 6 into the pipe bending mechanism 3 for pipe bending operation.

[0024] Referring to Figures 1 to 3 The pipe bending mechanism 3 includes a rotating disc 31, a rotating die 32, a rotating column 33, a sliding support assembly 34, and a pipe bending assembly 35. The middle section of the rotating column 33 is rotationally connected with the body 1, the lower end of the rotating disc 31 is fixedly connected with the upper end of the rotating column 33, the side of the rotating disc 31 is inserted with the rotating die 32, the rear end of the sliding support assembly 34 is bolted with the side of the body 1, and the pipe bending assembly 35 is fixedly connected with the lower end of the rotating column 33. The rotating column 33 is electrically controlled to rotate, and the motor thereof can be arranged in the body 1 and controlled by a controller to cooperate with the sliding support assembly 34 and the pipe bending assembly 35 to move. The rotating die 32 is a semicircular groove die, and the size of the groove is matched with the steel pipe 6. The rotating die 32 is detachably installed for maintenance and replacement, and different sizes of the rotating die 32 can be replaced to match different diameters or shapes of the steel pipe 6.

[0025] In the pipe bending operation, the limiting tube 24 pushes the steel pipe 6 into the rotating die 32, the rotating die 32 semi-encloses and limits the bending part of the steel pipe 6, the pipe bending assembly 35 semi-encloses and limits the bending part of the steel pipe 6 from the other side, so that the bending part is held by the rotating die 32 and the pipe bending assembly 35. Then the rotating column 33 rotates, driving the rotating disc 31 to rotate, and then driving the rotating die 32 and the pipe bending assembly 35 to move in a circular motion, so that the steel pipe 6 is bent. At the same time, the electric sliding arm 23 continues to displace, driving the steel pipe 6 to displace towards the rotating disc 31, and the sliding support assembly 34 synchronously slides to displace, providing support and limitation for the steel pipe 6, and preventing the steel pipe 6 from being broken by continuously conveying the steel pipe 6 forward.

[0026] Referring to Figures 1 to 3, the sliding support assembly 34 comprises a support frame 341, a second sliding rail 342, and a sliding support die 343; the lower end of the support frame 341 is bolted to the side of the machine body 1, the rear end of the second sliding rail 342 is inserted into the end of the support frame 341 away from the machine body 1, and the sliding support die 343 is electrically and slidingly connected to the second sliding rail 342. Among them, the sliding connection between the sliding die and the second sliding rail 342 can use the electrically driven sliding form of the motor cooperating with the screw rod and the threaded sleeve, or other electrically driven sliding mechanisms that can achieve the effect. The sliding support die 343 is a long strip-shaped semicircular slotted die, which can be disassembled and installed for easy maintenance and replacement.

[0027] When the limiting tube 24 pushes the steel pipe 6 to displace in the direction of the rotating disc 31, one side of the steel pipe 6 enters the sliding support die 343. During the pipe bending operation, the sliding support die provides a larger area of support for the steel pipe 6, preventing uneven stress on the steel pipe 6 due to the limiting tube 24 limiting the tail end of the steel pipe 6, which may cause deformation of the rear steel pipe 6.

[0028] Referring to Figures 1 to 3 , the pipe bending assembly 35 comprises a first support plate 351, a second support plate 352, a vertical plate 353, a first electric push rod 354, and a pipe bending die 355; the first support plate 351 and the second support plate 352 are both fixedly connected to the rotating column 33 at one end and fixedly connected to the vertical plate 353 at the other end. The front end of the first electric push rod 354 is bolted to the upper part of the vertical plate 353, and the output end of the first electric push rod 354 passes through the vertical plate 353 and is inserted into the rear end of the pipe bending die 355. Among them, the pipe bending die 355 can be disassembled and installed for easy maintenance and replacement, so that it can be replaced to adapt to steel pipes 6 of different sizes and shapes. During the pipe bending operation, the first electric push rod 354 pushes the pipe bending die 355 to displace in the direction of the rotating die 32, and the steel pipe 6 is completely clamped by the pipe bending die 355 and the rotating die 32. Then, when the rotating column 33 rotates, it drives the first support plate 351 and the second support plate 352 to rotate, thereby driving the vertical plate 353 to make a circular motion around the rotating disc 31, driving the pipe bending die 355 to rotate, and making the steel pipe 6 bend. After completion, the first electric push rod 354 drives the pipe bending die 355 to return to the original position, the rotating column 33 reverses to drive the vertical plate 353 and the rotating die 32 to return to the original position, and the sliding die reversely displaces to return to the original position, preparing for the next pipe bending operation.

[0029] As another embodiment, as Figure 3 and Figure 4As shown, the auxiliary clamping mechanism 4 comprises a second electric push rod 41, a double-sided rack 42, a connecting frame 43, two sets of gears 44, a first arc-shaped clamping plate 45, a second arc-shaped clamping plate 46 and a sliding support rod 47; the lower end of the sliding support rod 47 is electrically and slidably connected with the sliding groove 11, the upper end of the sliding support rod 47 is inserted with the connecting frame 43, the second electric push rod 41 is inserted with the connecting frame 43, the output end of the second electric push rod 41 passes through the connecting frame 43 and is inserted with the double-sided rack 42, the rear end of the first arc-shaped clamping plate 45 is fixedly connected with the double-sided rack 42, the gears 44 are rotationally connected with the connecting frame 43, the gears 44 are meshed with the double-sided rack 42, the sector teeth 5 are rotationally connected with the connecting frame 43, the sector teeth 5 are meshed with the gears 44, and the sector teeth 5 are fixedly connected with the second arc-shaped clamping plate 46.

[0030] The second electric push rod 41 drives the double-sided rack 42 to displace towards the steel pipe 6, thereby driving the gears 44 meshed with the double-sided rack 42 to rotate, driving the sector teeth 5 to rotate, so that the second arc-shaped clamping plates 46 on the upper and lower sides of the steel pipe 6 perform circumferential motion, and the steel pipe 6 is clamped and supported.

[0031] When the remaining length of the steel pipe 6 is short, the limiting pipe 24 cannot continue to displace due to the limitation of the sliding support assembly 34, and the steel pipe 6 can continue to displace towards the rotating disc 31 through the clamping of the first arc-shaped limiting plate and the second arc-shaped limiting plate and the sliding displacement of the sliding support rod 47, thereby providing multidirectional support for the rear part of the steel pipe 6 and ensuring that the tail part of the steel pipe 6 can smoothly perform the pipe bending operation.

[0032] It should be noted that the controller, the pushing mechanism 2, the pipe bending mechanism 3 and the auxiliary clamping mechanism 4 are all connected with each other through electrical signals and are linked and matched through the controller.

[0033] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
