[0028] As Figures 1 to 6 shown, an aluminum alloy fixed-length cutting device includes:

[0029] A bottom plate 1;

[0030] A feeding device, which is arranged on the bottom plate 1 and is used to move the aluminum alloy towards the cutting device;

[0031] A fixed-length device, which includes: a base 2, the base 2 is arranged on the bottom plate 1; a guide hole 3, the guide hole 3 is arranged at one end of the base 2 close to the feeding device; a push rod 4, the push rod 4 passes through the guide hole 3; a hinge rod 5, the lower part of the hinge rod 5 is hinged to the base 2, and the upper end of the hinge rod 5 is hinged to the push rod 4. Under the conveying action of the feeding device, the front end of the aluminum alloy approaches the lower end of the hinge rod 5 and pushes the hinge rod 5 to rotate;

[0032] A backing plate device, which includes: a smooth rod 6, the smooth rod 6 is vertically arranged between the base 2 and the feeding device; a bushing 7, the bushing 7 is sleeved on the smooth rod 6; a first elastic member 8, the first elastic member 8 is arranged between the lower end of the bushing 7 and the bottom plate 1; a backing plate 9, the backing plate 9 is arranged at the upper end of the outer wall of the bushing 7; a connecting rod 10, the connecting rod 10 is arranged at the lower end of the backing plate 9; a second elastic member 11, the second elastic member 11 is arranged between the backing plate 9 and the base 2, and the backing plate 9 is in close contact with the push rod 4 under the elastic potential energy of the second elastic member 11;

[0033] A cutting device, which includes: a knife groove 12, the knife groove 12 is arranged between the smooth rod 6 and the feeding device; a moving knife 13, the moving knife 13 is vertically elastically connected to the knife groove 12; a hammering mechanism, which is located directly above the moving knife 13.

[0034] The first elastic member 8 and the second elastic member 11 are springs or metal shrapnel.

[0035] During specific use, the feeding device conveys aluminum alloy to the cutting device. Before the front end of the aluminum alloy contacts the articulated rod 5, the hammering mechanism cannot strike the moving knife 13. When the front end of the aluminum alloy contacts the lower end of the articulated rod 5, it will push the articulated rod 5 to rotate. Under the guiding action of the guiding hole 3, the rotating articulated rod 5 drives the push rod 4 to move towards the knife groove 12, pushing the backing plate 9 to rotate to directly above the knife groove 12. The second elastic member 11 is stretched, and the hammering mechanism strikes the moving knife 13 through the backing plate 9. The backing plate 9 squeezes the first elastic member 8 downward, and the moving knife 13 descends to cut off the aluminum alloy. After cutting is completed, the extrusion force on the articulated rod 5 disappears, and the backing plate 9 resets under the elastic potential energy of the first elastic member 8 and the second elastic member 11 until the aluminum alloy pushes the articulated rod 5 to rotate again for the next cutting.

[0036] To achieve the purpose of adjusting the cutting length of the aluminum alloy, preferably, the base 2 includes a horizontal sliding groove 14 formed on the base 2 and a slider 15 slidably connected to the horizontal sliding groove 14. The lower part of the articulated rod 5 is hinged to the slider 15, and a first adjusting device for adjusting the position of the slider 15 is provided on the base 2;

[0037] Adjusting holes 16 are arranged along the length direction of the push rod 4.

[0038] Specifically, the first adjusting device is a screw or a telescopic device. When the first adjusting device is a screw, the screw is threadedly connected to the base 2, and one end of the screw is rotatably connected to the slider 15. By rotating the screw, the screw drives the slider 15 to move along the length direction of the horizontal sliding groove 14 to adjust the distance between the slider 15 and the cutting device. When the first adjusting device is a telescopic device, the telescopic device is a hydraulic cylinder or an electric push rod. The telescopic device is fixed on the base 2, and the telescopic end of the telescopic device is fixedly connected to the slider 15. By controlling the telescopic distance of the telescopic end of the telescopic device, the slider 15 is driven to move along the length direction of the horizontal sliding groove 14 to adjust the distance between the slider 15 and the cutting device;

[0039] After the position of the slider 15 is adjusted, the hinged position between the upper end of the articulated rod 5 and the push rod 4 is changed through the adjusting hole 16, thereby changing the cutting length of the aluminum alloy. For example, the adjusting hole 16 and the articulated rod 5 are connected by a pin shaft with external threads at both ends, and both ends of the pin shaft can be limited and fixed by nuts, and the pin shaft can rotate independently around the adjusting hole 16 or the articulated rod 5, so that this device can be suitable for cutting aluminum alloys of different lengths.

[0040] To achieve the purpose of feeding the aluminum alloy, preferably, the feeding device includes two feeding wheels 17 and two first driving parts 18. The first driving parts 18 are motors, and the two first driving parts 18 drive the two feeding wheels 17 to rotate.

[0041] Specifically, the two first driving parts 18 drive the corresponding feeding wheels 17 to rotate respectively, and convey the aluminum alloy to the cutting device through friction force.

[0042] To achieve the purpose of fixed-length cutting of aluminum alloys with different diameters, preferably, the feeding device further includes a "U"-shaped seat 19 arranged on the bottom plate 1. Guide grooves 20 are formed on the opposite side walls of the "U"-shaped seat 19. A "U"-shaped bracket 21 is slidably connected inside the guide grooves 20. One of the feeding wheels 17 is rotatably connected between the two side walls of the "U"-shaped bracket 21, and the other feeding wheel 17 is rotatably connected between the two side walls of the "U"-shaped seat 19. A second adjusting device for adjusting the position of the "U"-shaped bracket 21 is arranged on the "U"-shaped bracket 21.

[0043] Specifically, the second adjusting device is a screw rod or a telescopic device. When the second adjusting device is a screw rod, the screw rod is threadedly connected to the upper end of the "U"-shaped seat 19. When the second adjusting device is a telescopic device, the telescopic device is an electric push rod or a hydraulic cylinder. The distance between the two feeding wheels 17 is adjusted through the second adjusting device, which is suitable for the conveyance of aluminum alloys with different diameters, and thus fixed-length cutting is achieved.

[0044] To achieve the purpose of improving the cutting effect, preferably, the cutting device further includes a fixed knife 22, and the fixed knife 22 is arranged at the inner bottom of the knife groove 12.

[0045] Specifically, the fixed knife 22 and the moving knife 13 are arranged in a vertically staggered manner, increasing the shearing stress, making the cut of the aluminum alloy flat and having a good cutting effect.

[0046] To achieve the purpose of improving the cutting effect, preferably, a guide hole is formed at the upper end of the knife groove 12. A guide force block 23 is slidably connected inside the guide hole, and the moving knife 13 is arranged at the lower end of the guide force block 23.

[0047] A limiting groove 24 is formed at the edge of the guide hole. A limiting block 25 extending into the limiting groove 24 is arranged on the guide force block 23. A third elastic member 26 is arranged between the limiting block 25 and the inner bottom wall of the limiting groove 24, and the third elastic member 26 is a spring or a metal elastic sheet.

[0048] The hammering mechanism includes a mounting plate 27 arranged on the bottom plate 1. A second driving part 28 is arranged on the mounting plate 27. The second driving part 28 is a motor. A turntable 29 is arranged at the output end of the second driving part 28. A connecting rod 30 is eccentrically rotatably connected to the turntable 29. The lower end of the connecting rod 30 is hinged to a hammer rod 31 that is vertically slidably connected to the mounting plate 27.

[0049] Specifically, the second driving part 28 drives the turntable 29 to rotate. The turntable 29 drives the hammer rod 31 to make reciprocating lifting movements through the connecting rod 30. When the backing plate 9 does not rotate above the force guiding block 23, the force guiding block 23 is not stressed. When the backing plate 9 rotates above the force guiding block 23, the hammer rod 31 strikes the force guiding block 23 through the backing plate 9. The force guiding block 23 drives the moving knife 13 to move downward to form a shearing force with the fixed knife 22, cutting off the aluminum alloy. After the backing plate 9 resets, the moving knife 13 rises under the elastic potential energy of the third elastic member 26.

[0050] Compared with the prior art, through the cooperative setting of the bottom plate 1, the feeding device, the base 2, the guiding hole 3, the push rod 4, the articulated rod 5, the optical rod 6, the bushing 7, the first elastic member 8, the backing plate 9, the connecting rod 10, the second elastic member 11, the knife groove 12, the moving knife 13 and the hammering mechanism in the present invention, the feeding device conveys the aluminum alloy to the cutting device. Before the front end of the aluminum alloy contacts the articulated rod 5, the hammering mechanism cannot strike the moving knife 13. When the front end of the aluminum alloy contacts the lower end of the articulated rod 5, it will push the articulated rod 5 to rotate. Under the guiding action of the guiding hole 3, the rotating articulated rod 5 drives the push rod 4 to move towards the knife groove 12, pushing the backing plate 9 to rotate to the directly above the knife groove 12. The second elastic member 11 is stretched. The hammering mechanism strikes the moving knife 13 through the backing plate 9. The backing plate 9 squeezes the first elastic member 8 downward, and the moving knife 13 descends to cut off the aluminum alloy. After the cutting is completed, the extrusion force on the articulated rod 5 disappears. The backing plate 9 resets under the elastic potential energy of the first elastic member 8 and the second elastic member 11 until the aluminum alloy pushes the articulated rod 5 to rotate again for the next cutting, so that the lengths of the cut aluminum alloys are the same, simplifying the cutting process.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
