Description

Technical Field

[0001] This utility model belongs to the technical field of porous foam materials, specifically a diamond wire cutting machine for ultra-long foam aluminum plates. Background Technology

[0002] Foamed aluminum is made by adding additives to pure aluminum or aluminum alloys and then foaming it. It combines the characteristics of both metal and air bubbles. It has low density, strong impact absorption capacity, high temperature resistance, strong fire resistance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, strong weather resistance, filtering ability, easy processing, easy installation, high forming precision, and can be surface coated. It is an engineering material with great development potential.

[0003] Foamed aluminum sheets typically need to be cut before they can be used for further processing or applications. A commonly used cutting device for foamed aluminum sheets is a C-type diamond wire cutter. Chinese patent CN120095228A discloses a C-type diamond wire cutter, which includes an operating table, a cutting frame, a cutting mechanism, and a worktable. The cutting frame consists of a first horizontal arm, a second horizontal arm, and a connecting part forming a "C"-shaped frame structure. The cutting mechanism includes multiple cutting wheels and diamond wire. The multiple cutting wheels are evenly distributed on the first and second horizontal arms, and the diamond wire is wound around the multiple cutting wheels. Wire-passing holes are provided at opposite positions at one end of the first and second horizontal arms, and the diamond wire is led out from the two wire-passing holes as the cutting wire.

[0004] Existing C-type diamond wire cutting machines have poor versatility and cannot be used for ultra-long foamed aluminum sheets. The specific reasons are as follows:

[0005] like Figure 1 As shown, an existing C-type diamond wire cutting machine includes a cutting frame, which includes an upper horizontal arm 1, a lower horizontal arm 2, and a longitudinal arm 3. The upper horizontal arm 1 and the lower horizontal arm 2 are both straight arms. The upper horizontal arm 1 and the lower horizontal arm 2 are horizontally arranged and parallel to each other. The longitudinal arm 3 is vertically arranged and connects one end of the upper horizontal arm 1 and the lower horizontal arm 2 respectively to form a C-type cutting frame. A first guide wheel 4 is installed at the free end of the upper horizontal arm 1. A third guide wheel 6 is installed at the connection between the upper horizontal arm 1 and the longitudinal arm 3. A fourth guide wheel 7 is installed at the free end of the lower horizontal arm 2, facing the first guide wheel 4. A sixth guide wheel 9 is installed at the connection between the lower horizontal arm 2 and the longitudinal arm 3, facing the third guide wheel 6. A ring-shaped diamond wire 10 passes sequentially around the first guide wheel 4, the third guide wheel 6, the sixth guide wheel 9, and the fourth guide wheel 7. The diamond wire between the first guide wheel 4 and the fourth guide wheel 7 serves as the cutting line.

[0006] Existing C-type diamond wire cutting machines require a foam aluminum plate clamp to hold the foam aluminum plate, align it with the cutting line, and gradually move it from outside the C-type cutting frame to inside, thus cutting thick foam aluminum plates into thinner plates. Therefore, if... Figure 1As shown, existing C-type diamond wire cutting machines require the length of the C-type cutting frame (i.e., the lengths of the upper horizontal arm 1 and the lower horizontal arm 2) to be greater than the length of the aluminum foam board 12 in order to successfully complete the cutting. Figure 2 As shown, when the existing C-type diamond wire cutting machine is used to cut the extra-long foam aluminum board 11, the length of the C-type cutting frame (that is, the length of the upper horizontal arm 1 and the lower horizontal arm 2) is less than the length of the extra-long foam aluminum board 11. Due to the obstruction of the longitudinal arm 3, the entire extra-long foam aluminum board cannot be cut. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a diamond wire cutting machine for ultra-long foamed aluminum boards, which is highly versatile and suitable for cutting ultra-long foamed aluminum boards.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A first guide wheel is installed at the free end of the upper horizontal arm, a second guide wheel is installed at the corner of the upper horizontal arm, a third guide wheel is installed at the connection between the upper horizontal arm and the longitudinal arm, a fourth guide wheel is installed at the free end of the lower horizontal arm facing the first guide wheel, a fifth guide wheel is installed at the corner of the lower horizontal arm facing the second guide wheel, and a sixth guide wheel is installed at the connection between the lower horizontal arm and the longitudinal arm facing the third guide wheel. The annular diamond wire passes sequentially around the first guide wheel, the second guide wheel, the third guide wheel, the sixth guide wheel, the fifth guide wheel, and the fourth guide wheel, with the diamond wire between the first guide wheel and the fourth guide wheel serving as a cutting line.

[0011] As a preferred technical solution, at least one of the first guide wheel and the fourth guide wheel is a drive wheel, which rotates under the drive of the drive mechanism.

[0012] As a preferred technical solution, at least one of the third guide wheel and the sixth guide wheel is a tensioning wheel, which can move back and forth under the drive of the tensioning mechanism.

[0016] As a preferred technical solution, the included angle between the two arms of the lower cross arm is 120-150°.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention modifies the structure of the upper and lower horizontal arms of existing C-type diamond wire cutting machines. The upper horizontal arm is configured with a horizontal projection plane of a "︿" shape, and the lower horizontal arm is configured with a horizontal projection plane of a "︿" shape. A second guide wheel is installed at the corner of the upper horizontal arm, and a fifth guide wheel is installed at the corner of the lower horizontal arm, ensuring that the winding direction of the diamond wire is not in the same plane. When this diamond wire cutting machine cuts aluminum foam boards, the aluminum foam board is aligned with the cutting line and then moves towards the corner of the "︿" shape. The longitudinal arm does not obstruct the aluminum foam board. Therefore, this diamond wire cutting machine can cut aluminum foam boards of various lengths, has strong versatility, and is suitable for cutting extra-long aluminum foam boards.

[0025] like Figure 3 and Figure 4As shown, the diamond wire cutting machine of this utility model includes a cutting frame and a foam aluminum plate clamp; the cutting frame includes an upper horizontal arm 1 with a horizontal projection plane of U-shape, a lower horizontal arm 2 with a horizontal projection plane of U-shape, and a longitudinal arm 3. The upper horizontal arm 1 and the lower horizontal arm 2 are horizontally arranged and parallel to each other, and the longitudinal arm 3 is vertically arranged and connects one end of the upper horizontal arm 1 and the lower horizontal arm 2 respectively to form a cutting frame; a first guide wheel 4 is installed at the free end of the upper horizontal arm 1, a second guide wheel 5 is installed at the corner of the upper horizontal arm 1, and a [missing information - likely a type of guide wheel] is installed at the connection between the upper horizontal arm 1 and the longitudinal arm 3. The lower horizontal arm 2 is equipped with a third guide wheel 6, and a fourth guide wheel 7 is installed at the free end of the lower horizontal arm 2, which is directly opposite the first guide wheel 4. A fifth guide wheel 8 is installed at the corner of the lower horizontal arm 2, which is directly opposite the second guide wheel 5. A sixth guide wheel 9 is installed at the connection between the lower horizontal arm 2 and the longitudinal arm 3, which is directly opposite the third guide wheel 6. The annular diamond wire 10 passes around the first guide wheel 4, the second guide wheel 5, the third guide wheel 6, the sixth guide wheel 9, the fifth guide wheel 8 and the fourth guide wheel 7 in sequence. The diamond wire between the first guide wheel 4 and the fourth guide wheel 7 serves as a cutting line.

[0026] The included angle between the two arms of the upper horizontal arm 1 and the lower horizontal arm 2 is designed to allow the aluminum foam board to move toward the corner of the ︿ shape, without obstructing the aluminum foam board with the longitudinal arm 3. To achieve this, it has been verified that the included angle between the two arms of the upper horizontal arm 1 is preferably 90-160°, more preferably 120-150°; and the included angle between the two arms of the lower horizontal arm 2 is preferably 90-160°, more preferably 120-150°.

[0027] At least one of the first guide wheel 4 and the fourth guide wheel 7 is a drive wheel, which rotates under the drive of the drive mechanism. At least one of the third guide wheel 6 and the sixth guide wheel 9 is a tension wheel, which can move back and forth under the drive of the tensioning mechanism.

[0028] This invention modifies the structure of the upper and lower horizontal arms of the existing C-type diamond wire cutting machine. The upper horizontal arm 1 is configured with a horizontal projection plane of a "︿" shape, and the lower horizontal arm 2 is configured with a horizontal projection plane of a "︿" shape. A second guide wheel 5 is installed at the corner of the upper horizontal arm 1, and a fifth guide wheel 8 is installed at the corner of the lower horizontal arm 2, so that the winding direction of the diamond wire 10 is not in the same plane. Figure 4 As shown, when the diamond wire cutting machine of this utility model cuts the foam aluminum board, the foam aluminum board 11 is aligned with the cutting line and then moves toward the corner of the ︿ shape. The longitudinal arm 3 will not block the foam aluminum board 11. Therefore, the diamond wire cutting machine of this utility model can cut foam aluminum boards of various lengths, has strong versatility, and is suitable for cutting extra-long foam aluminum boards.
