Description

Technical Field

[0001] This utility model relates to the technical field of aluminum strip bending equipment, and in particular to a bending knife and bending machine. Background Technology

[0002] The manufacturing of aluminum spacers typically requires bending the aluminum strips, usually at a 90-degree angle. Bending equipment is needed for this process. For example, Chinese patent CN221790651U discloses an automatic bending device for aluminum spacers in insulating glass. In this device, the cylinder's return stroke uses a limiting shaft to press and fix the blade rod in a positioning groove, achieving rapid engagement of the bending blade. Controlling the cylinder's push stroke allows for quick separation of the bending blade, offering the advantage of easier replacement. However, the width of this bending blade is fixed. During processing, aluminum strips of varying widths need to be processed. When the aluminum strip is too wide or too narrow, the thickness of the bending blade differs from the strip's width, affecting the bending quality. Alternatively, replacing the bending blade with a different size would also impact processing efficiency.

[0003] Therefore, in order to address the above problems, a bending knife and bending machine are proposed to solve them. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a bending knife and bending machine, which allows for adjustment of the width of the bending knife.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a bending knife, including a mounting table and a clamping block on the mounting table, the clamping block clamps the aluminum strip, a mounting seat is provided on the mounting table, and a first bending knife and a second bending knife are provided on the mounting seat, and the gap between the first bending knife and the second bending knife is adjusted by an adjustment structure.

[0006] Adjust the distance between the first bending blade and the second bending blade according to the aluminum strip of different widths, so that the first bending blade and the second bending blade work together to bend the aluminum strip, which is suitable for aluminum strips of different widths.

[0007] Preferably, the adjustment structure includes a mounting base, on which a cylinder is mounted, the output end of which is connected to a mounting plate, and a first bending blade is mounted on the mounting plate.

[0008] The cylinder pushes the mounting base to move, which in turn moves the first bending blade, thereby adjusting the distance between the first and second bending blades to accommodate bending aluminum strips of different widths.

[0009] Preferably, guide rods are symmetrically arranged on the mounting base. The guide rods pass through the mounting plate and the first bending blade. The mounting plate is slidably connected to the guide rods, the first bending blade is slidably connected to the guide rods, and the guide rods are connected to the second bending blade, which is located below the positioning base.

[0010] Both the mounting plate and the first bending blade are slidably connected to the guide rod, which limits the movement of the first bending blade and prevents it from deviating during its movement.

[0011] Preferably, a connecting block is provided at the lower part of the first bending cutter, the connecting block is located on the side of the first bending cutter close to the second bending cutter, and a first cutter head is provided at the lower part of the connecting block.

[0012] Preferably, a second cutter head is provided at the lower part of the second bending cutter, and a slot is provided at the connection between the second cutter head and the second bending cutter, with a connecting block fitting inside the slot.

[0013] The first and second bending cutters fit together through the slot and connecting block, allowing the first and second cutting heads to be in contact. This controls the distance between the first and second cutting heads and reduces the space occupied by them.

[0014] Preferably, a limiting plate is provided on the clamping block, a connecting rod is provided on the limiting plate, a connector is provided on the connecting rod near the first bending blade, a bearing is provided on the connector for rotation, and the bearing is attached to the outer surface of the first bending blade.

[0015] The distance between the first and second bending blades is adjusted. The first and second bending blades press against the bending point of the aluminum strip. The clamping block moves to clamp the aluminum strip. The bearing is connected to the first bending blade. After bending is completed, the first and second bending blades retract. The bearing and connecting rod limit the movement to prevent the first bending blade from colliding with the clamping block when it retracts.

[0016] A bending machine, including a bending blade.

[0017] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0018] Adjust the distance between the first bending blade and the second bending blade according to the aluminum strip of different widths, so that the first bending blade and the second bending blade work together to bend the aluminum strip, which is suitable for aluminum strips of different widths;

[0019] The first and second bending cutters fit together through the slot and connecting block, allowing the first and second cutting heads to be in contact. This controls the distance between the first and second cutting heads and reduces the space occupied by them. Attached Figure Description

A mounting base 4 is provided on the mounting table, and a first bending knife 2 and a second bending knife 3 are mounted on the mounting base 4. The gap between the first bending knife 2 and the second bending knife 3 is adjusted by an adjustment structure. Depending on the width of the aluminum strip, the gap between the first bending knife 2 and the second bending knife 3 is adjusted so that the first bending knife 2 and the second bending knife 3 work together to bend the aluminum strip, making it suitable for aluminum strips of different widths.

[0027] The adjustment structure includes a mounting base 4, on which a cylinder 5 is mounted. The output end of the cylinder 5 is connected to a mounting plate 6, on which a first bending blade 2 is mounted. The cylinder 5 pushes the mounting base 4 to move, thereby moving the first bending blade 2 and adjusting the distance between the first bending blade 2 and the second bending blade 3, thus adapting to bending aluminum strips of different widths.

[0028] Guide rods 7 are symmetrically arranged on the mounting base 4. The guide rods 7 pass through the mounting plate 6 and the first bending blade 2. The mounting plate 6 is slidably connected to the guide rods 7, and the first bending blade 2 is also slidably connected to the guide rods 7. The guide rods 7 are connected to the second bending blade 3, which is located below the positioning base 8. Both the mounting plate 6 and the first bending blade 2 are slidably connected to the guide rods 7. The guide rods 7 limit the movement of the first bending blade 2 to prevent it from shifting during its movement.

[0029] A connecting block 11 is provided at the lower part of the first bending cutter 2. The connecting block 11 is located on the side of the first bending cutter 2 close to the second bending cutter 3. A first cutter head 12 is provided at the lower part of the connecting block 11.

The connecting block 11 is fitted inside the slot 14. The first bending cutter 2 and the second bending cutter 3 are fitted together by the slot 14 and the connecting block 11, so that the first cutter head 12 and the second cutter head 13 are fitted together. This can control the distance between the first cutter head 12 and the second cutter head 13, and reduce the space occupied by the first cutter head 12 and the second cutter head 13.

[0031] A limiting plate 9 is provided on the clamping block 1, and a connecting rod 10 is provided on the limiting plate 9. A connector 15 is provided on the connecting rod 10 near the first bending blade 2. A bearing 16 is rotatably mounted on the connector 15 and rests on the outer surface of the first bending blade 2. After adjusting the distance between the first bending blade 2 and the second bending blade 3, the first bending blade 2 and the second bending blade 3 press against the bending point of the aluminum strip. The clamping block 1 moves to press the aluminum strip. The bearing 16 rests on the first bending blade 2. After bending is completed, the first bending blade 2 and the second bending blade 3 retract. The bearing 16 and the connecting rod 10 limit the movement to prevent the first bending blade 2 from colliding with the clamping block 1 during retraction.
