Description

Technical Field

[0002] With the development of modern industry, pipeline systems are increasingly used in various industries, such as petroleum, chemical industry, construction, medicine, etc. As an important part of the pipeline system, the elbow is used to connect two pipes to change the direction of the fluid while ensuring the flow and pressure of the fluid. In practical applications, the elbow also needs to have certain corrosion resistance and pressure resistance. Therefore, the processing quality of the elbow is crucial to the safe operation of the entire pipeline system.

[0003] Existing pipe bending processing equipment mainly includes pipe bending machines and cutting machines. The pipe bending machine causes the pipe to undergo plastic deformation through certain mechanical actions, thereby forming the required bending angle. The cutting machine is used to cut the pipe before and after the pipe bending process to meet the length requirements of the pipeline system. However, the clamping part of the existing pipe bending cutting equipment can only clamp pipes of the same diameter and the same bending angle, and then cut them. If you want to cut pipes of different angles or diameters, you need to replace the clamping mold, which means that once you need to cut pipes of different diameters or different bending angles, the existing clamping part will not be able to meet the demand. In this case, the clamping mold must be replaced to ensure the smooth progress of the cutting process. This process of replacing the mold is time-consuming and troublesome, which seriously affects production efficiency.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] The working principle of the utility model is as follows Figure 1-Figure 7 As shown, a pipe bending processing and cutting device includes a base plate 1, and both sides of the top of the base plate 1 are fixedly connected with slide rails 2, and the slide rails 2 are provided with a plurality of evenly distributed through holes 3, and a slider 4 is slidably connected to the slide rails 2. The sliders 4 can be set in plurality, and the sliders 4 and the slide rails 2 are connected to each other by setting a limiting structure 5, which also means that multiple components thereon can also be set, and the multiple components are used in conjunction with each other. Through the limiting structure 5, the distance between the sliders 4 on the same slide rail 2 is adjusted, thereby meeting the requirements for clamping and fixing pipes of different lengths.

[0023] A clamping part 6 is fixedly connected between the sliders 4 on both sides, and a clamping opening 7 is opened on the clamping part 6, and a structure for clamping the bent pipe is arranged therein, and the structure specifically includes a clamping ring 8 whose bearing is connected to the inside of the clamping opening 7, and a plurality of evenly distributed limit frames 9 are arranged at the front end of the clamping ring 8, and a clamping ring 2 10 is arranged at the front end of the limit frame 9, and the limit frame 9 is connected to the clamping ring 1 8 and the clamping ring 2 10 by an insertion shaft 2 11, and a clamping rod 12 is arranged in the limit frame 9, and a plurality of evenly distributed insertion shafts 13 rotatably connected to the clamping rod 12 are fixedly connected to the front end of the clamping part 6, therefore, when the clamping ring 1 8 is turned to rotate, the clamping ring 2 10 rotates synchronously, and the corresponding limit frame 9 clamped between the clamping ring 1 8 and the clamping ring 2 10 will change its position, thereby driving the clamping rod 12 therein to perform a circular motion around the insertion shaft 1 13, thereby realizing the adjustment of the clamping diameter.

[0024] In order to realize the above operation, the utility model is fixedly connected to a connecting rod 18 on one side of the bottom end of the clamping ring 8, and a threaded block 19 is rotatably connected to the connecting rod 18. The internal thread of the threaded block 19 is connected to a threaded column 20, and a crank 21 is fixedly connected to one end of the threaded column 20, and a rotating block 22 is rotatably connected to the other end of the threaded column 20. The rotating block 22 is rotatably connected to the clamping portion 6. Therefore, by shaking the crank 21, the threaded column 20 can be rotated. Under the influence of the threaded connection, the threaded block 19 moves on the threaded column 20, and synchronously drives the connecting rod 18 rotatably connected to it to rotate, thereby driving the clamping ring 8 to move, thereby realizing the above-mentioned clamping and adjustment function.

[0025] At the same time, a clamping groove 14 is formed on the side of the clamping rod 12 away from the insertion shaft 13, and a clamping plate 15 is arranged in the clamping groove 14 for use therewith, and the clamping plate 15 and the clamping groove 14 are connected to each other by a plurality of evenly distributed dampers 16, and a spring 17 is sleeved on the outside of the damper 16, and the two ends of the spring 17 are respectively connected to the clamping plate 15 and the clamping groove 14. Therefore, when the user puts the bent pipe to be cut into the clamping mouth 7, the shaking handle 21 is turned to adjust the clamping degree, and the clamping plates 15 in the clamping groove 14 move closer to or away from each other until they are tightly attached to the bent pipe, and continue to adjust until the damper 16 and the spring 17 are contracted to the extreme, at which time the bent pipe is clamped, and the arrangement of multiple dampers 16 and springs 17 also makes it possible to clamp the bent pipe, realizing more possibilities.

[0026] Finally, a driving structure 23 is disposed at the front end of the base plate 1, and a cutting assembly 24 for use with the driving structure 23 is disposed above the driving structure 23.

[0029] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the pulling part 28 is pulled, the pin 25 is moved by the force and begins to disengage from the groove 26 and the through hole 3. At this time, the limit block 30 approaches the limit plate 31 and squeezes the spring 29 to deform it. Only when the pin 25 is completely disengaged from the groove 26 and the through hole 3, the slider 4 and the clamping part 6 thereon are released from the slide rail 2. The user can move the slider 4 and the clamping part 6 thereon to the desired position, and align the pin 25 with the through hole 3 at the target position, and let go. The pin 25 is reset under the deformation force of the spring 29, and the slider 4 and the slide rail 2 are fixed again.

[0030] In order to further explain the specific working principle of a pipe bending and cutting device of the utility model, the above-mentioned driving structure 23 includes a bottom plate 2 32 which is horizontally arranged in front of the bottom plate 1, and threaded blocks 2 33 are arranged on both sides above the bottom plate 32.

[0031] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the bent pipe is clamped, the motor 2 37 is started to drive the screw rod 35 to rotate. Under the influence of the threaded connection, the threaded block 2 33 moves on the screw rod 35, and the positioning rod 34 is used to maintain its stability during the movement until it moves to the desired position.

However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0035] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
