[0027] Example

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a steel pipe cutting device for a steel pipe production line, including a processing table 1, a material guiding and collecting mechanism is provided above the processing table 1, and the material guiding and collecting mechanism includes a V-shaped clamping base 2, an inclined collecting table 21, a first servo electric cylinder 22, a lifting plate 23 and an inclined top plate 24, so as to realize the automated discharge and collection of the cut steel pipe through the material guiding and collecting mechanism;

[0029] A cutting protection mechanism is installed above the processing table 1. The cutting protection mechanism includes a protective shell 3, a movable plate 31, a guide rod 32, a V-shaped clamping block 33, a second servo electric cylinder 34, a filter sleeve 35, an exhaust fan 36, and an activated carbon filter plate 37. The cutting protection mechanism enables automated cutting of steel pipes and collects and filters harmful gases generated during cutting.

[0030] By protecting the steel pipes during cutting and filtering out the metal fumes generated during the cutting process, harm to the health of operators can be avoided. Furthermore, by automating the unloading and collection of the cut steel pipes, not only is the manual labor required for collection reduced, but work efficiency is also improved.

[0031] The lower end of the V-shaped clamping base 2 is fixedly connected to the upper end of the processing table 1. The V-shaped clamping base 2 is provided with a clearance groove for use and cooperation in cutting. Since it belongs to the prior art, it is not shown in the figure. The interior of the V-shaped clamping base 2 is provided with a storage groove 25 distributed in a linear array.

[0032] The lower end of the inclined collection platform 21 is fixedly connected to the upper end of the processing table 1, and the back of the inclined collection platform 21 is fixedly connected to the front of the V-shaped clamping base 2. The inclined collection platform 21 is set at an inclination, which facilitates the rolling discharge of the cut steel pipe. A symmetrically distributed limiting plate is set above the inclined collection platform 21 to limit and guide the movement of the steel pipe.

[0033] The front of the inclined collection platform 21 extends through and to the front of the protective housing 3. The lower end of the first servo electric cylinder 22 is fixedly installed on the inner bottom wall of the processing table 1. One end of the piston rod of the first servo electric cylinder 22 is fixedly connected to the lower end of the lifting plate 23. The lower ends of the two inclined top plates 24 are symmetrically distributed and fixedly connected to the upper end of the lifting plate 23. The upper end of the inclined top plate 24 extends through the processing table 1 and into the interior of the storage groove 25. The first servo electric cylinder 22 drives the inclined top plate 24 to move up and down through the lifting plate 23. After descending, the inclined top plate 24 is located inside the storage groove 25 to avoid obstructing the cutting process. When rising, it pushes out the cut steel pipe through the inclined surface.

[0034] A third servo electric cylinder 26 is fixedly installed on the upper end of the processing table 1. One end of the piston rod of the third servo electric cylinder 26 is fixedly connected to an L-shaped baffle 27. The third servo electric cylinder 26 drives the L-shaped baffle 27 to move and adjust, thereby automatically adjusting the cutting length of the steel pipe and quickly determining the cutting position of the steel pipe.

[0035] The lower end of the protective housing 3 is fixedly connected to the upper end of the processing table 1. A feed trough 38 is provided on one side of the protective housing 3, and an inspection door 39 is provided on the other side of the protective housing 3. The inspection door 39 facilitates the maintenance and cleaning of the inside of the processing table 1. The lower end of the piston rod of the second servo electric cylinder 34 is fixedly installed to the upper end of the protective housing 3.

[0036] One end of the piston rod of the second servo electric cylinder 34 is fixedly connected to the lower end of the movable plate 31. Two guide rods 32 are symmetrically distributed and fixedly connected to the lower end of the movable plate 31. The lower end of the guide rod 32 passes through the protective shell 3 and is fixedly connected to the upper end of the V-shaped clamping block 33. The extension and retraction of the piston rod of the second servo electric cylinder 34 drives the guide rod 32 to move up and down through the movable plate 31, and cooperates with the V-shaped clamping block 33 to clamp and position the steel pipe, which is convenient for subsequent cutting.

[0037] A fourth servo electric cylinder 310 is fixedly installed on the inner top wall of the protective housing 3. One end of the piston rod of the fourth servo electric cylinder 310 is fixedly connected to the cutting mechanism body 311. The cutting mechanism body 311 adopts existing cutting equipment, so it will not be described in detail. The fourth servo electric cylinder 310 plays the role of driving the cutting mechanism body 311 to move up and down for cutting.

[0038] The back of the protective housing 3 is fixedly connected to the front of the filter sleeve 35. The exhaust fan 36 is installed inside the filter sleeve 35. The activated carbon filter plate 37 is movably inserted into the upper end of the filter sleeve 35. The back of the filter sleeve 35 is fixedly connected to the conveying pipe 312. The exhaust fan 36 draws the metal fumes generated during cutting into the filter sleeve 35. After the fumes are filtered by the activated carbon filter plate 37, they are then conveyed to the subsequent equipment for harmless discharge through the conveying pipe 312.

[0039] The working process of this utility model:

[0040] Step 1: Start the piston rod of the third servo electric cylinder 26 to move the L-shaped baffle 27, thereby adjusting the cutting distance of the steel pipe. Then, move the steel pipe through the feed chute 38 into the protective housing 3, and place one end of it in contact with the L-shaped baffle 27 and above the V-shaped clamping base 2. Then, start the piston rod of the second servo electric cylinder 34 to retract and drive the movable plate 31 to descend. The descent of the movable plate 31 drives the V-shaped clamping block 33 to descend and move through the guide rod 32, which cooperates with the V-shaped clamping base 2 to clamp and fix the steel pipe.

[0041] Step 2: The piston rod of the fourth servo electric cylinder 310 is extended, thereby driving the cutting mechanism body 311 to cut the steel pipe. At this time, the exhaust fan 36 works to draw the metal fumes generated during cutting into the filter sleeve 35. After being purified by the activated carbon filter plate 37, the fumes are transported through the conveying pipe 312 to the subsequent treatment mechanism for harmless discharge.

[0042] Step 3: After cutting is completed, the fourth servo electric cylinder 310 drives the cutting mechanism body 311 to retract and reset, and the piston rod of the second servo electric cylinder 34 extends, thereby driving the V-shaped clamping block 33 to rise and reset. At the same time, the piston rod of the first servo electric cylinder 22 drives the lifting plate 23 to rise and move. The lifting plate 23 drives the inclined top plate 24 to rise and disengage from the collection groove 25. The rise of the inclined top plate 24 squeezes the cut steel pipe, and through the cooperation of the inclined surface, the steel pipe disengages from the V-shaped clamping base 2 and enters the inclined collection platform 21. It then rolls down the inclined surface of the inclined collection platform 21 into the collection container. At this time, the piston rod of the first servo electric cylinder 22 drives the lifting plate 23 to descend and reset into the collection groove 25. The operator continues to push one end of the steel pipe to contact the L-shaped baffle 27 to achieve continuous cutting operation.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
