Description

Technical Field

[0001] This invention specifically relates to a multifunctional pipe fitting processing equipment and a processing method. Background Technology

[0002] In the pipe fittings processing industry, forming, assembly, and end treatment are essential processes. Currently, these processes are mostly completed independently using single-function equipment, such as pipe bending machines, fitting machines, and pipe end treatment machines. However, this single-function processing method has significant drawbacks, such as long processing cycles, large footprint, and the need for frequent pipe fitting transfers. These limitations restrict the improvement of production efficiency. Specifically, the problems in existing technologies mainly include: process separation: Since each process requires different equipment, this leads to discontinuity in the entire processing, increasing production costs; large footprint: Single-function equipment occupies a large production space, which is not conducive to optimizing the factory's internal space; excessive manual operation: The need for manual handling and adjustment of pipe fitting positions between different processes increases labor intensity and reduces processing efficiency; high equipment investment: To meet the needs of different processes, companies need to purchase multiple types of equipment, which undoubtedly increases equipment investment costs.

[0003] In addition, in traditional pipe fitting processing technology, when multiple bends need to be processed on the pipe fitting and nuts need to be fitted on the pipe fitting, the pipe fitting needs to be bent into shape in multiple places first, and then the nuts need to be fitted on the bent pipe fitting. This makes the pipe fitting processing inefficient and cannot be completed in a single process. Moreover, the difficulty of fitting nuts after the pipe fitting is bent increases, which is not conducive to quality control.

[0004] This invention was developed precisely because of the aforementioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multifunctional pipe fitting processing equipment that is easy to produce and improves efficiency.

[0006] The invention is achieved through the following technical solution:

The base is also provided with a pushing mechanism located on one side of the pipe end mechanism for pushing the annular component fitted onto the pipe fitting to the first end of the pipe fitting.

[0008] The multi-functional pipe processing equipment described above also includes a conveying mechanism located on one side of the machine base for transporting pipes between the bending mechanism, the fitting mechanism, and the pipe end mechanism.

When the rotating seat rotates, the backing die presses the pipe along the pipe bending groove.

The pressure mold base is provided with a pipe end pressure mold that can press against the end of the pipe fitting when it moves toward the clamping channel.

[0012] As described above, in the multi-functional pipe fitting processing equipment, the lower clamping block is provided with a lower groove that matches the pipe fitting, and the upper clamping block is provided with an upper groove that matches the lower groove. When the upper and lower clamping blocks approach each other, the upper and lower grooves close together to form a clamping channel for clamping the end of the pipe fitting.

[0013] In the multi-functional pipe fitting processing equipment described above, the pushing mechanism is a high-pressure gas nozzle, which is connected to a high-pressure gas pipeline, and the outlet end of the high-pressure gas nozzle faces the lower groove of the lower clamping block.

[0014] The present invention also provides a method for processing pipe fittings, characterized by comprising the following steps:

[0015] A. The pipe bending mechanism bends the first end of the pipe fitting to form the first bend.

[0016] B. The kit mechanism fits the annular component onto the pipe fitting;

[0018] D. The pipe end mechanism will press the end of the pipe fitting into the opening;

[0019] E. The secondary bending mechanism bends the pipe fitting at the side near the end of the first bending section to form the second bending section.

It is easy to operate and improves production efficiency. Attached Figure Description

[0028] The invention will be further described below with reference to the accompanying drawings:

[0029] The orientations described in this invention specification, such as "up," "down," "left," "right," "front," "back," "clockwise," and "counterclockwise," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components.

[0030] like Figures 1 to 5As shown, this embodiment provides a multifunctional pipe fitting processing equipment for processing pipe fitting A, which has a head end A1 and an end end A2. The equipment is mainly capable of bending and forming the head end A1 of pipe fitting A, and then performing a butt-forming process after fitting a nut onto the end end A2 of pipe fitting A.

In this embodiment, the conveying mechanism 6 adopts a multi-axis manipulator, but other conveying structures can also be used, or the pipe fitting A can be transported by manual handling.

[0032] As a preferred embodiment of the pipe bending mechanism 2, such as Figure 2As shown, the pipe bending mechanism 2 includes a pipe bending base 21, a rotating seat 22 that can rotate relative to the pipe bending base 21, and a first driving device 23 for pushing the rotating seat 22 to rotate.

The rotating seat 22 is provided with a sliding seat 25 that can move towards the pipe bending mold 24, and a second driving device 23 for pushing the sliding seat 25 to slide. 6. The sliding seat 25 is provided with a pressing mold 251 that can press the pipe A located in the bending groove 241 when it is close to the bending mold 24. The bending base 21 is also provided with a pressing seat 27 that can move toward the bending mold 24 and a third driving device 28 for pushing the pressing seat 27 to move. The pressing seat 27 is provided with a backing mold 271 that can abut against the pipe A when it is close to the bending mold 24. When the rotating seat 22 rotates, the backing mold 271 presses the pipe A along the bending groove 241. The first drive device 23 can be a motor or a rotary cylinder, with its output shaft connected to the rotating seat 2. Similarly, the second drive device 26 can be a cylinder, hydraulic cylinder, or linear motor, with its output shaft connected to the sliding seat 22. Likewise, the third drive device 28 can be a cylinder, hydraulic cylinder, or linear motor, with its output shaft connected to the bending seat 4. Of course, all three can also refer to the patent scheme of patent number CN201310634656.4, entitled "A Bending Mechanism for a Pipe Bending Machine". During operation, the die 251 presses the pipe against the bending groove 211, and the rotating seat 2 rotates to make the pipe follow the rotation. At this time, the die 41 is fixed and presses against the pipe, so that the pipe is bent and formed along the bending groove 211.

Figure 6As shown, the secondary pipe bending mechanism 8 includes a second pipe bending base 81, which is connected to a second rotating seat 82 that can rotate relative to it, and an eighth driving device 83 for pushing the second rotating seat 82 to rotate. The second rotating seat 82 is provided with a second pipe bending mold 84 located at its rotation center.

[0034] As a preferred embodiment of the kit mechanism 3, such as Figure 3 and Figure 4 As shown, the annular component B is a nut. The kit mechanism 3 includes a kit base 31, a kit slide 32 that can slide laterally relative to the kit base 31, and a fourth drive device 33 for pushing the kit slide 32 to slide laterally.

The side of the kit clamp 36 is provided with a fitting insertion hole 362 that communicates with the placement groove 361 and allows the fitting A to pass through the nut in the placement groove 361. During operation, the nut is placed vertically in the placement groove 361, and then the end A2 of the fitting A is inserted into the fitting insertion hole 362 by a multi-axis robot. Then, the lifting seat 34 is driven to descend by the fifth drive device 35, thereby putting the nut on the fitting A.

[0035] As a preferred embodiment of the pipe end mechanism 4, such as Figure 5As shown, the pipe end mechanism 4 includes a pipe end base 41, a lower clamping block 42 on the pipe end base 41, an upper clamping block 43 on the pipe end base 41 that can move up and down relative to it to approach or move away from the lower clamping block 42, and a sixth driving device 44 for pushing the upper clamping block 43 to move. The pipe end base 41 is connected to a pressing mold seat 45 that can slide relative to it and move toward the clamping channel, and a seventh driving device 46 for pushing the pressing mold seat 45 to move. The pressing mold seat 45 is provided with a pipe end pressing mold 46 that can press against the end A2 of the pipe fitting A when it moves toward the clamping channel. During operation, the neck of the end A2 of the pipe fitting is clamped by the upper clamping block 43 of the lower clamping block 42, that is, the position between the end A2 of the pipe fitting A and the middle of the pipe fitting A is clamped. Then, the pressing mold seat 45 is pushed to move by the seventh driving device 46, and then the end A2 of the pipe fitting A is pressed to the flattening nozzle by the pipe end pressing mold 46. Preferably, the lower clamping block 42 is provided with a lower groove 421 that matches the pipe fitting A, and the upper clamping block 43 is provided with an upper groove 431 that matches the lower groove 421. When the upper clamping block 43 and the lower clamping block 42 approach each other, the upper groove 431 and the lower groove 421 close together to form a clamping channel for clamping the end of the pipe fitting A.

[0036] As a preferred implementation of the push mechanism 5, such as Figure 5 As shown, the pushing mechanism 5 is a high-pressure gas nozzle, which is connected to a high-pressure gas pipeline, and the outlet end of the high-pressure gas nozzle faces the lower groove 421 of the lower clamping block 42.

[0037] Preferably, the base 1 is also provided with a feeding mechanism 7 for conveying nuts to the placement slot 361 of the kit clamp 36. The feeding mechanism 7 adopts a vibratory feeder mechanism, which includes a vibratory feeder and a feeding channel. The output end of the feeding channel is set to correspond with the kit clamp 36. The specific structure can adopt the structure of the vibratory feeder with patent number CN202323498285.X and name "A Vibratory Feeder with Adjustable Output", which belongs to the prior art and will not be described in detail.

[0038] Preferably, the conveying mechanism 6 is a multi-axis robotic arm.

[0039] The processing method using the multifunctional pipe fitting processing equipment of this embodiment includes the following steps:

[0040] A. The pipe bending mechanism 2 bends the first end of the pipe fitting A to form the first bent part A4;

[0041] B. The kit mechanism 3 fits the annular component B onto the pipe fitting A;

[0042] C. Pushing mechanism 5 pushes the annular component B, which is fitted on pipe fitting A, to the first end A1 of pipe fitting A;

[0043] D. Pipe end mechanism 4 will abut the end A2 of pipe fitting A;

[0044] E. The secondary bending mechanism 8 bends the pipe fitting A at the side of the first bending section A4 near the end of the pipe fitting A to form the second bending section A5.

[0045] The ring component B is pushed to the beginning of the pipe A by the pushing mechanism 5, so that the bending process can continue between the beginning of the pipe A A1 and the middle of the pipe A. This ensures that the ring component B will not slide or shift during the processing and transportation of the pipe A, which would prevent the subsequent bending process from being completed normally. This allows for the processing of multiple bends on the same machine and the fitting of ring components such as nuts on the pipe, achieving automated one-time processing of finished products and improving production efficiency.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
