DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the embodiment, Figure 1-5 A pipe bending machine for ship production is provided, comprising a bottom plate 1, a lateral moving assembly 2 is arranged at the top of the bottom plate 1, a fixing assembly 3 for fixing a steel pipe is arranged at the top of the lateral moving assembly 2, and a bending assembly 4 for bending the steel pipe is arranged at the top of the bottom plate 1;

[0025] The bending assembly 4 includes a steering gear 41, the top of the base plate 1 is fixedly connected to the steering gear 41, the rear end of the steering gear 41 is fixedly connected to the first servo motor 42, the input end of the steering gear 41 is fixedly connected to the output end of the first servo motor 42, a turntable 43 is fixedly connected to the outer side of the output end of the steering gear 41, a semicircular frame 44 is fixedly connected to the top of the turntable 43, a slide groove 45 is opened on the inner side of the semicircular frame 44, a sliding mechanism 46 is slidably connected to the inner side of the slide groove 45, and a steel pipe fixing part 47 is fixedly connected to the sliding mechanism 46.

[0026] Through the above arrangement, the steering gear 41 contains a group of mutually meshing bevel gears, which can output the power of the first servo motor 42 to, first put the steel pipe into the steel pipe fixing part 47, and fix it through the fixing component 3, start the first servo motor 42, and transmit the power to the turntable 43 through the steering gear 41, and drive the semicircular frame 44, the sliding mechanism 46 and the steel pipe fixing part 47 to rotate through the turntable 43. Since the steel pipe is fixed by the fixing component 3, the steel pipe fixing part 47 will drive the steel pipe to bend. If the steel pipe needs to be processed into a more complex shape, such as the bent part of the steel pipe is bent in another direction, the sliding mechanism 46 can be started to slide along the inner side of the slide groove 45, thereby changing the position of the steel pipe fixing part 47, and then the bent part of the steel pipe is bent in another direction.

[0027] Reference Figure 1-5 , wherein the transverse moving assembly 2 includes a slide rail 21, the top of the bottom plate 1 is fixedly connected to the slide rail 21, and two pulleys 22 are arranged on the left and right sides, and the four pulleys 22 are rotatably connected to the bottom of the transverse sliding seat 23, and the top of the transverse sliding seat 23 is fixedly connected to a second servo motor 24, and an output end of the second servo motor 24 penetrates and extends to the bottom of the transverse sliding seat 23, and the outer side of the output end of the second servo motor 24 is fixedly connected to a first transmission gear 25, and the transverse sliding seat 23 is fixedly connected to a spur rack 26 meshing with the first transmission gear 25;

[0028] Through the above-mentioned structural setting, the second servo motor 24 is started, and the first transmission gear 25 is driven by the second servo motor 24 to rotate. Since the first transmission gear 25 and the spur rack 26 are meshed with each other, the first transmission gear 25 will move linearly along the spur rack 26, thereby changing the position of the transverse sliding seat 23. At this time, the four pulleys 22 slide along the left and right ends of the slide rail 21 respectively until the position of the fixing component 3 corresponds to the steel pipe fixing piece 47, so as to facilitate the fixing of the steel pipe.

[0029] Reference Figure 1-5 , wherein the fixing assembly 3 includes a fixing base 31, the top of the transverse sliding seat 23 is fixedly connected to the fixing base 31, the top of the fixing base 31 is fixedly connected to two cylinders 32, and the output ends of the two cylinders 32 are fixedly connected to the clamping mechanism 33;

[0030] Through the above-mentioned structural setting, the two cylinders 32 are started at the same time, so that the two clamping mechanisms 33 change their positions at the same time, so that the clamping center of the clamping mechanism 33 corresponds to the steel pipe fixing piece 47, which is convenient for fixing the steel pipe. It should be noted that the working principle of the clamping mechanism 33 is common knowledge of technicians in the relevant technical field, and the clamping mechanism 33 is any clamping device that can be used to clamp the steel pipe. It is a prior art and will not be described in detail.

[0031] Reference Figure 1-5 , wherein the sliding mechanism 46 includes an arc-shaped base 461, the inner side of the slide groove 45 is slidably connected with the arc-shaped base 461, the right end of the arc-shaped base 461 is fixedly connected with a third servo motor 462, the outer side of the output end of the third servo motor 462 is fixedly connected with a second transmission gear 463, the outer side of the semicircular frame 44 is provided with an arc-shaped rack 464 meshing with the second transmission gear 463, and the steel pipe fixing member 47 is fixedly connected to the left end of the arc-shaped base 461;

[0032] Through the above-mentioned structural setting, the third servo motor 462 is started, and the second transmission gear 463 is driven by the third servo motor 462 to rotate. Since the second transmission gear 463 and the arc-shaped rack 464 are meshed with each other, the second transmission gear 463 will move in an arc along the outer side of the arc-shaped rack 464. At this time, the arc-shaped base 461 slides along the inner side of the slide groove 45, thereby changing the position of the arc-shaped base 461 and the steel pipe fixing piece 47, so that the bent part of the steel pipe is bent in another direction.
