Description

Technical Field

[0001] The utility model relates to the technical field of automatic aluminum bar saws, and particularly relates to a sawing device for aluminum bars. Background Art

[0002] In order to improve the processing efficiency of aluminum bars, an automatic aluminum bar saw is used to cut aluminum bars. It is a kind of efficiency for aluminum bar processing. The automatic aluminum bar saw conveys the aluminum bars to the cutting chamber through a roller conveyor and cuts them under the fixation of a cylinder. The fixation of the cylinder is achieved by driving a pressing plate to press the top of the aluminum bar. However, since the aluminum bar is circular, the contact area between the aluminum bar and the pressing plate is small. Moreover, the cutting direction of the automatic aluminum bar saw is horizontally perpendicular to the aluminum bar. During cutting, the force applied by the cutting knife may cause the aluminum bar to have a risk of deviation, which may lead to damage to the cutting knife. Secondly, the inner size of the roller conveyor is fixed, and it is impossible to ensure that the aluminum bar moves parallel to the conveyor inside the conveyor during transportation, resulting in an inclined angle on the end face of the cut aluminum bar.

Specific embodiments

[0033] Embodiment 1

[0034] As Figure 1-5 shown, a sawing device for aluminum bars proposed by the present utility model includes a cutting chamber 1, a mounting frame 2, a downward pressing structure 3, a pressing plate 4, a spiral idler roller 8 and a driving assembly;

[0035] The mounting frame 2 is arranged at the inlet of the cutting chamber 1. The number of spiral idler rollers 8 is multiple, and multiple spiral idler rollers 8 are all rotatably mounted inside the mounting frame 2 to guide the aluminum bar towards the inner wall of the mounting frame 2 in the conveying state;

[0036] The downward pressing structure 3 is mounted at the top of the mounting frame 2 and at the inlet of the cutting chamber 1 to move downward in the use state to press the aluminum bar conveyed by the spiral idler roller 8;

[0037] The pressing plate 4 is mounted at the inner bottom end of the downward pressing structure 3 and at the inlet of the cutting chamber 1 to limit the aluminum bar conveyed by the spiral idler roller 8; wherein, the bottom end of the pressing plate 4 has a fixing groove, and the fixing groove is arc-shaped and has a size adapted to the diameter of the aluminum bar

[0038] The driving assembly includes a motor 6 and a transmission member 7; the motor 6 is mounted on the side of the mounting frame 2 and is in transmission connection with the spiral idler roller 8; the transmission member 7 is mounted at the end of the spiral idler roller 8 to synchronously rotate multiple spiral idler rollers 8 in the use state. Among them, the transmission member 7 is a prior art such as a chain drive structure, so the structure is not specifically shown in the figure.

[0039] In this embodiment, the aluminum rod is conveyed to the inner side of the mounting frame 2 through the feeding structure, and is supported by a plurality of spiral rollers 8. Meanwhile, the motor 6 drives one spiral roller 8 to rotate, and the spiral roller 8 drives a plurality of spiral rollers 8 to rotate synchronously through the transmission member 7, so that the spiral rollers 8 convey the aluminum rod to the inner side of the cutting chamber 1. At the same time, the spiral rollers 8 move the aluminum rod towards the inner wall of the mounting frame 2 during the conveying process. When the aluminum rod moves to the cutting chamber 1, the aluminum rod is parallel to the inner wall of the mounting frame 2, and the pressing structure 3 drives the pressing plate 4 to move downward, so that the pressing plate 4 limits the aluminum rod. Meanwhile, the pressure of the pressing structure 3 fixes the aluminum rod on the spiral roller 8 through the pressing plate 4, and cuts the aluminum rod inside the cutting chamber 1, avoiding damage to the cutting tool caused by displacement of the end of the aluminum rod due to the cutting direction being perpendicular to the moving direction of the aluminum rod.

[0040] Embodiment Two

[0041] As Figure 4-5 shown, a sawing device for aluminum rods proposed by the present utility model. Compared with Embodiment One, in this embodiment, the pressing structure 3 includes a cylinder 31, a fixing frame 32 and a connecting plate 33;

[0042] The fixing frame 32 is installed at the top of the mounting frame 2 and has a U-shaped shape;

[0043] The cylinder 31 is installed on the upper end surface of the fixing frame 32. The piston rod of the fixing frame 32 penetrates through the top of the fixing frame 32. And the number of cylinders 31 is at least one to avoid the situation that the pressure on both sides of the connecting plate 33 is relatively small when applying pressure to the aluminum rod, so that a plurality of aluminum rods conveyed on the spiral roller 8 are subjected to the same pressure;

[0044] The connecting plate 33 is installed at the bottom end of the cylinder 31 and is located inside the fixing frame 32. Among them, a chute is provided at the bottom end of the connecting plate 33, and a slider is provided at the top end of the pressing plate 4. When the connecting plate 33 and the pressing plate 4 are installed in cooperation, the slider of the pressing plate 4 is accommodated in the chute inside the connecting plate 33, which is used for disassembling and assembling the pressing plate 4 in the use state, replacing the fixing groove at the bottom end of the pressing plate 4, so that the pressing plate 4 is adapted to aluminum rods of different diameters.

[0045] Embodiment Three

[0046] As Figure 4-6 shown, a sawing device for aluminum rods proposed by the present utility model. Compared with Embodiment Two, in this embodiment, one end of the chute of the connecting plate 33 is open, and a fixing component 5 is provided on the side surfaces of the connecting plate 33 and the pressing plate 4;

[0047] The fixing component 5 includes a latch A51, a latch B52 and a locking rod 54; the latch A51 and the latch B52 are respectively installed on the sides of the connecting plate 33 and the pressing plate 4; the locking rod 54 is inserted inside the latch B52 and the latch A51, and a magnet 53 is arranged inside the bottom end of the locking rod 54.

[0048] In this embodiment, the pressing plate 4 can be quickly disassembled and assembled through the opening of the sliding groove of the connecting plate 33. By inserting the locking rod 54 inside the latch A51 and the latch B52, the disassembly of the pressing plate 4 is blocked, and the pressing plate 4 is fixed at the bottom end of the connecting plate 33 to prevent it from falling off during use.

[0049] Embodiment 4

[0050] As Figure 3 shown, a sawing device for aluminum bars proposed by the present utility model. Compared with Embodiment 1, in this embodiment, the spiral supporting roller 8 includes a roller shaft 81 and a spiral sleeve 82;

[0051] The roller shaft 81 is rotatably installed inside the mounting frame 2 and is used to convey the aluminum bar to the cutting chamber 1 through the starting structure; the spiral sleeve 82 is sleeved outside the roller shaft 81, and the outer side has spiral threads for moving the aluminum bar towards the inner wall of the mounting frame 2 in the use state. A clamping groove is arranged on the outer side of the roller shaft 81, and a convex strip is arranged on the inner side of the spiral sleeve 82. When the roller shaft 81 and the spiral sleeve 82 are installed in cooperation, the convex strip of the spiral sleeve 82 is fitted and accommodated inside the clamping groove of the roller shaft 81 to fix the position of the spiral sleeve 82 on the roller shaft 81 in the use state, preventing the roller shaft 81 from rotating inside the spiral sleeve 82 due to the heavy weight of the aluminum bar, resulting in the inability to transport the aluminum bar.

[0052] In summary, when the present utility model is in use, the aluminum bar is conveyed to the inside of the mounting frame 2 through the feeding structure, and is supported by a plurality of spiral supporting rollers 8. At the same time, the motor 6 drives one spiral supporting roller 8 to rotate, and the spiral supporting roller 8 drives a plurality of spiral supporting rollers 8 to rotate synchronously through the transmission member 7, so that the spiral supporting rollers 8 convey the aluminum bar towards the inside of the cutting chamber 1. At the same time, the aluminum bar is moved towards the inner wall of the mounting frame 2 during the conveying process through the spiral threads on the outer side of the spiral sleeve 82. When the aluminum bar moves to the cutting chamber 1, the aluminum bar is parallel to the inner wall of the mounting frame 2. The air cylinder 31 drives the connecting plate 33 to move downward, so that the connecting plate 33 drives the pressing plate 4 to move towards the aluminum bar. The fixing groove of the pressing plate 4 is connected to the top end of the aluminum bar and wraps around the top end of the aluminum bar, so that the fixing groove of the pressing plate 4 limits the aluminum plate, and the pressing plate 4 is pressed on the aluminum plate by the pressure of the pressing structure 3 to further fix the aluminum bar, and the aluminum bar is cut by the cutting knife inside the cutting chamber 1 whose cutting direction is perpendicular to the moving direction of the aluminum bar.
