Description

Technical Field

[0001] The invention relates to the technical field of conveying mechanisms, in particular to a conveying mechanism for alloy profile processing. Background Art

[0002] Alloy profiles usually refer to an alloy material with aluminum as the main component. The most common processing of alloy profiles is cutting. The alloy profiles need to be cut into different lengths according to the design requirements. In actual work, the cutting disc is usually fixed in position, and the length of the alloy profile needs to be conveyed and controlled to determine the cutting position. When using traditional conveying mechanisms, the conveying position must usually be adjusted first, and then clamped and fixed for processing. After clamping, the conveying length cannot be adjusted again. When the conveying length needs to be fine-tuned multiple times, the clamping must be released each time, which is inconvenient to use and not conducive to higher-precision control.

[0027] The adjustment component includes a centering spring 101 and a toggle screw 102. The centering spring 101 is symmetrically arranged at the two end positions of the I-shaped slide 4.

[0030] The processing control unit includes a limit frame 501, a right-angle frame 502 and a driving shaft 503. The limit frame 501 is fixedly installed on the U-shaped buckle plate 5. The right-angle frame 502 is limited and inserted through the limit frame 501. The driving shaft 503 is fixedly arranged on the right-angle frame 502.

[0031] A frame support 504 is fixedly provided on the surface of the limiting frame 501, and a double-headed screw 505 is rotatably provided on the frame support 504. The double-headed screw 505 is provided with mutually symmetrical threads. The double-headed screw 505 is spirally matched with the right-angle bow frame 502.

An end blind hole 510 is opened at the end of the double-headed screw 505, and the top shaft portion 509 is limitedly inserted in the end blind hole 510. An axial elastic force is applied to the double-headed screw 505 through the spring plate 508, and at the same time, the double-headed screw 505 and the top shaft portion 509 can rotate relative to each other.

[0033] A central gear 511 is fixedly disposed in the middle of the double-headed screw 505, a synchronous dial 512 is disposed on one side of the central gear 511, and a toggle cam 513 is disposed outside the synchronous dial 512. When the toggle cam 513 rotates, the synchronous dial 512 can be toggled to move along the axis direction of the double-headed screw 505, so that the spring sheet 508 is compressed; A rotation driver 514 and a gear power module 516 are fixedly arranged on the surface of the U-shaped gusset plate 5. The rotation driver 514 is used to drive the toggle cam 513 to rotate. The gear power module 516 is provided with a driving gear 515. The gear power module 516 is used to drive the driving gear 515 to rotate. The driving gear 515 is meshed with the central gear 511. The driving gear 515 and the central gear 511 can move relative to each other axially to ensure that the gear matching width between the driving gear 515 and the central gear 511 is sufficient, so that when the double-headed screw 505 oscillates axially back and forth, the meshing between the driving gear 515 and the central gear 511 can be maintained.

[0034] A rising touch plate 601 is provided on the surface of the processing splint 6, and the processing splint 6 is in squeeze contact with the alloy profile through the rising touch plate 601. The rising touch plate 601 can move up and down along the surface of the processing splint 6. A rubber pad is attached to the surface of the rising touch plate 601. The rubber pad increases the contact friction between the rising touch plate 601 and the alloy profile, making it easier to move the alloy profile upward by rising the rising touch plate 601, and at the same time protecting the alloy profile to avoid being pinched.

[0035] A cylindrical inner cavity 602 is provided inside the processing splint 6, and a limiting flange 603 is provided on the inner wall surface of the cylindrical inner cavity 602 near the upper end. A piston body 604 is provided inside the cylindrical inner cavity 602, and the piston body 604 is in air-tight contact with the cylindrical inner cavity 602. A rising vertical shaft 605 is fixedly provided on the upper part of the piston body 604, and the rising vertical shaft 605 is fixedly installed with the rising touch plate 601; a downward pressure spring 606 is provided above the piston body 604, and the downward pressure spring 606 applies downward elastic pressure to the piston body 604. A branch air path 607 and a gathering air path 608 are provided inside the processing splint 6, and an air pressure control nozzle 609 is fixedly provided on the surface of the processing splint 6, and the lower end of the cylindrical inner cavity 602 is connected with the air pressure control nozzle 609 through the branch air path 607 and the gathering air path 608. When the mechanism is working, the air pressure control nozzle 609 is connected with an external compressed gas pipeline.

[0036] When the conveying mechanism for alloy profile processing of the present invention is used, Figure 1 As shown in , the alloy profile is placed above the conveying roller 2. The rolling of the conveying roller 2 reduces friction, so that the alloy profile can be easily conveyed and moved. The alloy profile can be manually pushed axially to achieve preliminary control of length conveying.

[0037] like Figure 2 As shown in the figure, the gear power module 516 drives the driving gear 515 to rotate, so that the driving gear 515 drives the central gear 511 and the double-headed screw 505 to rotate. When the double-headed screw 505 rotates, the right-angle bow frames 502 on both sides gather and move, and the processing splint 6 gathers and moves through the driving shaft 503, so that the processing splint 6 clamps the alloy profile.

[0038] At this time, the fine-tuning wheel 104 is manually turned to rotate the lead screw 102. Through the limited engagement between the lead screw 102 and the linear rack 107, the telescopic clamp 106 and the U-shaped buckle plate 5 are driven to move along the axial direction of the lead screw 102, thereby adjusting the position of the U-shaped buckle plate 5, so that the conveying length of the alloy profile clamped by the processing clamp 6 can be adjusted with high precision.

[0039] When the alloy profile is cut, the rotary driver 514 drives the toggle cam 513 to rotate, so that the toggle cam 513 squeezes and pushes the synchronous dial 512, and the double-headed screw 505 moves axially back and forth through the reset elastic cooperation with the spring 508. Since the spacing between the two sets of right-angle bow frames 502 does not change, the processing clamp 6 maintains a clamping state for the alloy profile, and the axial reciprocating movement of the double-headed screw 505 will drive the alloy profile to oscillate back and forth parallel to the tangent direction. The oscillation makes the cutting tool intermittently contact with the alloy profile, reducing continuous friction, reducing cutting resistance, and at the same time improving the chip removal effect. The increase in the gap during the oscillation separation process can be beneficial to chip discharge.

[0040] During the above process, compressed gas is input through the air pressure control nozzle 609, such as Figure 7 As shown in the figure, the compressed gas enters the cylindrical inner cavity 602 through the branch gas path 607, pushing the piston body 604 upward, causing the rising touch plate 601 to move upward, and the processing clamping plate 6 moves upward through the rising touch plate 601, driving the alloy profile to move upward, so that the alloy profile is separated from the conveying roller 2, avoiding friction scratches on the surface of the alloy profile caused by friction between the alloy profile and the conveying roller 2.

[0041] After the processing is completed, the gear power module 516 is used to control the driving gear 515 to reverse, so that the processing clamp 6 is separated and released, and then the telescopic clamp 106 is controlled to retract and move through the electric control telescope 105, so that the linear rack 107 and the toggle screw 102 are no longer limited in engagement. At this time, under the elastic thrust of the centering spring 101, the U-shaped buckle plate 5 and the I-shaped slide bar 4 will reset to the initial position, and then the telescopic clamp 106 will be controlled to extend and restore the limited engagement state.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
