Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy pipe processing, and particularly relates to a multi-angle cutting and processing device for corrosion-resistant aluminum alloy pipes. Background Art

[0002] In the modern industrial field, aluminum alloy pipes are widely used in many industries such as aerospace, petrochemical, construction engineering, and automobile manufacturing due to their excellent physical properties, such as light weight, good strength, and strong corrosion resistance. In these application scenarios, aluminum alloy pipes often need to be precisely cut and processed according to specific engineering design and installation requirements. When cutting and processing aluminum alloy pipes, a cutting and processing device is used.

[0003] However, when the current cutting and processing device cuts and processes aluminum alloy pipes, since it is necessary to manually operate the positioning structure (for example, when the clamp clamps the aluminum alloy pipe, it is necessary to manually rotate the threaded rod structure) to position the aluminum alloy pipe, it is time-consuming and laborious to cut and process the aluminum alloy pipe, and the efficiency is low. Moreover, when the clamp on the current cutting and processing device clamps the aluminum alloy pipe, the clamping force of the clamping block is completely controlled manually by the staff. When facing an aluminum alloy pipe with a thinner pipe wall, manually controlling the clamping force easily causes the aluminum alloy pipe to deform due to excessive clamping force during clamping. Therefore, the quality of the cutting and processing device when processing aluminum alloy pipes is reduced. Summary of the Invention

[0004] Embodiments of the present disclosure relate to a multi-angle cutting and processing device for corrosion-resistant aluminum alloy pipes. Through the cooperation of a lifting mechanism and two pressing components, when the telescopic rod of the electric cylinder is controlled to extend downward, the two pressing components can automatically press and position the aluminum alloy pipe in advance, so that manual operation for positioning is not required, making the cutting and processing of the aluminum alloy pipe more time-saving and labor-saving, and thus improving the processing efficiency of the present cutting and processing device; through the setting of a pressing force adjusting component, before cutting the aluminum alloy pipe, the pressing force of the upper positioning block can be adjusted according to the thickness of the pipe wall of the aluminum alloy pipe, thereby avoiding the phenomenon that the aluminum alloy pipe is deformed due to excessive clamping force, and there is no need for manual control of the clamping force.

[0025] The cutting mechanism 4 includes a rotating shaft 401, a cutting blade 402 and a cutting motor 403.

Through the cooperation of the lifting mechanism 2 and the two pressing assemblies 5, when the telescopic rod of the electric cylinder 201 is controlled to extend downward, the two upper positioning blocks 501 first contact the upper side of the outer peripheral surface of the aluminum alloy pipe, and the aluminum alloy pipe is clamped and positioned by the two downward pressing upper positioning blocks 501, so that manual positioning is not required, making the aluminum alloy pipe more time-saving and labor-saving during cutting and processing, and thus improving the processing efficiency of the cutting device.

[0027] The pressing force adjusting assembly 6 includes a pressing force adjusting plate 601, an adjusting screw rod 602, a driving nut 603 and an adjusting rotating rod 604.

Through the setting of the pressing force adjusting assembly 6, the pressing force of the upper positioning block 501 can be adjusted according to the thickness of the aluminum alloy pipe wall. Thus, when the upper positioning block 501 presses and positions the aluminum alloy pipe with a thinner wall, the pressing force can be reduced, thereby avoiding the phenomenon that the aluminum alloy pipe is deformed due to excessive clamping force.

[0028] Embodiment 2, on the basis of Embodiment 1, as Figure 1 and Figure 8 shown, the anti-loosening mechanism 7 includes a sliding box body 701, a sliding block 702, a top pressing block 703, a locking gear 704, a locking block 705, a lower pull rod 706 and a handle 707. The sliding box body 701 is fixedly installed on the front end face of the C-shaped fixing plate 203, and a sliding block 702 is slidably connected inside the sliding box body 701. A top pressing block 703 is fixedly connected to the upper end face of the sliding block 702, which penetrates the top of the sliding box body 701, and two locking blocks 705 are fixedly connected to the upper end face of the top pressing block 703.

And a spring is sleeved on the outside of the lower pull rod 706 inside the sliding box body 701, and a handle 707 is fixedly connected to the lower end of the lower pull rod 706. When the anti-loosening mechanism 7 is in the locked and limited state, the upper end of the locking block 705 is in close contact with the lower side of the outer peripheral surface of the locking gear 704. Through the setting of the anti-loosening mechanism 7, after the adjusting rotating rod 604 is rotated and adjusted, the handle 707 can be released, so that the upper end of the locking block 705 is in close contact with the lower side of the outer peripheral surface of the locking gear 704, thereby locking and limiting the locking gear 704, and effectively avoiding the phenomenon that the adjusting rotating rod 604, the driving nut 603 and the adjusting screw rod 602 become loose.

[0029] Working principle of this embodiment: During use, first place the aluminum alloy pipe to be processed into the V-shaped grooves formed on the two lower positioning blocks 102. Then start the cutting motor 403, which drives the driving pulley, the driven pulley, the rotating shaft 401 and the cutting blade 402 to rotate. Next, control the telescopic rod of the electric cylinder 201 to extend downward, driving the lifting plate 202, the two pressing components 5, the cutting angle adjusting mechanism 3 and the cutting processing mechanism 4 to move downward. Then the two upper positioning blocks 501 first come into contact with the upper side of the outer circumference of the aluminum alloy pipe, and the aluminum alloy pipe is clamped and positioned by the two downward pressing upper positioning blocks 501. Next, the rotating cutting blade 402 comes into contact with the upper side of the outer circumference of the aluminum alloy pipe, and the aluminum alloy pipe is cut and processed by the rotating cutting blade 402.

[0030] Before cutting the aluminum alloy pipe, the pressing force of the upper positioning block 501 can be adjusted according to the thickness of the wall of the aluminum alloy pipe. For example, when encountering an aluminum alloy pipe with a thinner wall, the adjusting rod 604 can be manually rotated in the reverse direction to drive the second bevel gear, the first bevel gear and the driving nut 603 to rotate in the reverse direction. At this time, the adjusting screw 602 moves linearly upward under the action of the thread, driving the pressing force adjusting plate 601 to move upward, so as to adjust the telescopic length of the spring outside the vertical sliding rod 502, and further adjust the pressing force of the upper positioning block 501. In this way, when the upper positioning block 501 presses and positions the aluminum alloy pipe with a thinner wall, the pressing force can be reduced.

[0031] Before rotating the adjusting rod 604, pull the handle 707 downward with the other hand, driving the lower pull rod 706, the sliding block 702, the pressing block 703 and the locking block 705 to move downward, so that the upper end of the locking block 705 is separated from the lower side of the outer circumference of the locking gear 704. At this time, it will not affect the rotation of the adjusting rod 604. After the adjusting rod 604 is rotated and adjusted, release the handle 707. At this time, the sliding block 702 drives the pressing block 703 and the locking block 705 to move upward under the elastic force of the spring outside the lower pull rod 706, so that the upper end of the locking block 705 is in close contact with the lower side of the outer circumference of the locking gear 704, thereby locking and limiting the locking gear 704.
