Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile part machining, in particular to an aluminum alloy automobile part cutting device. BACKGROUND

[0002] With the aggravation of the automobile lightening trend, thin aluminum alloy sheets are widely used in the manufacturing of automobile body coverings, battery pack end plates and other parts due to the advantages of light weight and high specific strength. However, the thin aluminum alloy sheets have low yield strength and poor rigidity, and face significant technical problems in the cutting process.

[0003] When the existing cutting device cuts the thin aluminum alloy sheet, it is difficult to achieve uniform distribution and effective constraint of the cutting force due to the limitations of the structural design. During the cutting process, the radial cutting force applied by the saw blade acts on the local area of the cut, causing the imbalance of the stress of the sheet; at the same time, the thin aluminum alloy sheet lacks an adaptive support structure inside, which cannot offset the local cutting stress, and is prone to cause the inward collapse of the cut edge or the warping deformation due to uneven stress distribution. This not only damages the flatness and size accuracy of the cut, causes the cooperation gap of the subsequent welding and assembly process to exceed the standard, and increases the processing cost; but also may weaken the structural strength of the part and affect the safety performance of the automobile.

[0004] In the patent application with the application publication number CN121104189A, a base is provided with a cutting mechanism, a positioning mechanism and a cooling mechanism. The cutting mechanism includes a connecting cylinder, a rotating cylinder, two mounting frames and two cutting discs. A horizontal shaft and a vertical shaft are rotatably installed in the mounting frame. The cutting disc is fixedly installed on the outside of the horizontal shaft. A horizontal slot is formed on one side of the mounting frame. A pressure sensor is fixedly installed in the horizontal slot. A horizontal plate is slidably installed in the horizontal slot. A rotating frame is fixedly sleeved on the outside of the connecting cylinder. The horizontal plate is slidably sleeved on the outside of the rotating frame. The rotating cylinder is rotatably sleeved on the outside of the connecting cylinder. The cooling mechanism includes a fixed cylinder, a vertical pipe and two cooling nozzles. One end of the cooling nozzle is slidably installed in the vertical pipe. The vertical pipe is communicated with a horizontal pipe on one side. The horizontal pipe is rotatably installed on one end of the fixed cylinder. The advantages are as follows: a double-cutting-disc self-rotation and circumferential-feeding composite motion mode is adopted, which is matched with a dynamically adjusted radial feeding speed, so that the cutting load is uniformly distributed, the vibration and stress concentration are reduced, and the deformation of the thin-walled part is effectively controlled.

[0005] In the prior art including the above-mentioned patent, the main reason for the warping of the plate-shaped aluminum alloy workpiece during cutting is that a large amount of residual stress is easily accumulated in the interior during rolling or flattening, and when the original overall structure of the plate is destroyed by cutting, the originally balanced internal stress is redistributed, causing the plate to instantaneously twist or pop up. The composite motion mode of the self-rotation of the double-cutting disc and the circumferential feeding has low applicability and is difficult to cope with the deformation of the thin aluminum alloy plate during cutting. Therefore, the present application provides an aluminum alloy automobile part cutting device. SUMMARY

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

The terms "comprising" or "including," and similar terms used in this disclosure, mean that an element or object preceding the term encompasses the elements or objects listed following the term and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0022] Example 1 like Figures 1 to 8As shown, the present invention provides an aluminum alloy automotive parts cutting device, including a base 1, a saw unit 2, a workpiece support platform 3, and a backing member 4. A cutting slit 10 is provided on the base 1. The saw unit 2 is assembled on the base 1 for performing cutting operations on a thin aluminum alloy plate 7 along the cutting slit 10. The workpiece support platform 3 is located on the opposite side of the base 1. The backing member 4 is located on the workpiece support platform 3. One side of the thin aluminum alloy plate 7 can abut against the backing member 4. The device also includes a pressing component 5 and a lateral limiting component 6. The pressing component 5 is linked to the backing member 4 and can press against the upper surface of the thin aluminum alloy plate 7. The lateral limiting component 6 is located on the base 1 and can contact the side of the thin aluminum alloy plate 7. The movable saw unit 2 can cut the thin aluminum alloy plate 7 along the cutting slit 10 and leave an uncut allowance at the cut end of the thin aluminum alloy plate 7.

[0023] The main reason for warping during the cutting of thin aluminum alloy plate 7 is that a large amount of residual stress easily accumulates inside during the rolling or leveling process. When the cutting destroys the original overall structure of the plate, the original balanced internal stress will be redistributed, causing the plate to twist or bounce instantly. To this end, this device can effectively reduce the collapse of thin aluminum alloy plate 7 during cutting by providing a narrower cutting kerf 10. The base 1 can provide a large area of ​​support from the bottom surface of thin aluminum alloy plate 7. At the same time, in order to counteract the destructive force during the cutting of thin aluminum alloy plate 7, it is necessary to provide a vertically downward pressure and a horizontally backward thrust to thin aluminum alloy plate 7. The vertically downward force is used to counteract the upward force generated by the rotation of the saw blade and the high-frequency vibration of the thin aluminum alloy plate 7 itself, while the horizontally backward thrust is used to counteract the pulling force at the moment of saw blade entry and the small displacement during operation. Meanwhile, when cutting the thin aluminum alloy plate 7, the warping of the plate is further reduced by controlling the stroke. The thin aluminum alloy plate 7 is placed on the base 1 and abuts against the backing piece 4. The pressing component 5 presses it down while the side limit component 6 contacts the side to limit the collapse and warping of the thin aluminum alloy plate 7. When moving or rotating the saw unit 2, the push is stopped when the saw blade completely cuts the last 1-2 mm of the width of the thin aluminum alloy plate 7, so that the main body and the cut part are still connected at the end. After the thin aluminum alloy plate 7 is removed, it can be fatigued and broken by bending it up and down multiple times.

[0024] It also includes a guide rail limiting rod 8, which is mounted on the push-pull guide rail of the saw unit 2. Rotating the guide rail limiting rod 8 can adjust the maximum advance distance of the saw unit 2. To further control the size of the uncut allowance of the thin aluminum alloy plate 7 to be cut, such as... Figure 1 As shown, the thickness of the board and the cutting depth of the saw blade are measured in advance, and the guide rail travel corresponding to "1-2mm before complete cutting" is calculated. The position of the limit block is adjusted by the bolts, and the maximum advance distance of the saw unit 2 is locked. When cutting, when the saw unit 2 advances to the position of the limit block, it will be forcibly blocked and cannot continue to advance, stopping precisely at the target position.

[0025] like Figures 2-3 As shown, the clamping assembly 5 includes a rotating rod 50, a connecting rod 51, and a clamping member 52. The rotating rod 50 is vertically and rotatably mounted on the support member 4. One end of the connecting rod 51 is connected to the rotating rod 50, and the other end is rotatably connected to the clamping member 52. Rotating the rotating rod 50 can drive the connecting rod 51 to move vertically. Flipping the clamping member 52 can cause the clamping member 52 to rotate at one end of the connecting rod 51. The clamping member 52 can switch from a state of clamping the thin aluminum alloy plate 7 to a state of releasing the thin aluminum alloy plate 7. That is, when the clamping assembly 5 is in the cutting state, it can apply a vertically downward force to the thin aluminum alloy plate 7 to keep it in a stationary state; flipping the clamping member 52 reduces the vertical pressure, allowing the thin aluminum alloy plate 7 to remain against the support member 4, but it can move on the workpiece support table 3.

[0026] like Figure 3 As shown, the support member 4 includes a support plate 40 and a movable plate 41. The movable plate 41 restricts the movement of the top of the support plate 40 in the horizontal direction. The rotating rod 50 is vertically arranged on the movable plate 41. The support members 4 can move closer or further away from each other, thereby driving the pressing assembly 5 to move on the horizontal plane. In order to further increase the adaptability of the device, the base 1 can be rotated within a certain range, that is, by rotating the base 1, the thin aluminum alloy plate 7 can be cut at different angles.

[0027] like Figure 3As shown, the clamping component 52 includes a clamping plate 520, an adjusting plate 521, a first adjusting rod 522, and a first spring 523. The bottom surface of the clamping plate 520 contacts the top surface of the thin aluminum alloy plate 7. The top surface of the adjusting plate 521 is rotatably connected to one end of the connecting rod 51. The first adjusting rod 522 passes through the adjusting plate 521 and is rotatably connected to the top surface of the clamping plate 520. The first spring 523 is sleeved on the outer wall of the first adjusting rod 522, and the upper and lower ends of the first spring 523 contact the adjusting plate 521 and the clamping plate 520, respectively. A raised section 524 is provided at the end of the clamping plate 520 away from the cutting seam 10. A first roller 525 is provided on the raised section 524. When the clamping plate 520 is flipped until the raised section 524 is close to the thin aluminum alloy plate 7, the first roller 525 contacts the top surface of the thin aluminum alloy plate 7, pushing the thin aluminum alloy plate 7 to move on the workpiece support platform 3. Preferably, a flip handle 526 is provided on one side of the raised section 524. The clamping member 52 is elastically pressed against the thin aluminum alloy plate 7. The clamping force of the clamping member 52 on the thin aluminum alloy plate 7 can be adjusted by rotating the first adjusting rod 522 and the rotating rod 50. When the operator has completed one cut on the thin aluminum alloy plate 7, the saw blade of the saw unit 2 stops moving. The operator can manually flip the flip handle 526 downwards, which can drive the raised section 524 to move closer to the thin aluminum alloy plate 7 and the clamping plate 520 away from the raised section 524 to gradually move away from the upper surface of the thin aluminum alloy plate 7. The operation continues until the first roller 525 contacts the top surface of the thin aluminum alloy plate 7. Since the axis of the first roller 525 is perpendicular to the backing member 4, the operator can push the thin aluminum alloy plate 7 to move on the workpiece support table 3.

[0028] It should be noted that a rubber pad is provided on the bottom surface of the clamping plate 520 to reduce the indentation of the clamping assembly 5 on the top surface of the thin aluminum alloy plate 7, thereby reducing the breakage rate of the thin aluminum alloy plate 7.

[0029] like Figures 4 to 6As shown, the lateral limiting assembly 6 includes a connecting plate 60, a second adjusting rod 61, a second spring 62, a side push box 63, and a second roller 64. The connecting plate 60 is fixed to the base 1 and symmetrically arranged along the cut seam 10. The second adjusting rod 61 horizontally passes through the connecting plate 60 and is connected to the side push box 63. Several second rollers 64 are arranged on the side of the side push box 63 near the backing member 4. The second rollers 64 contact the side of the thin aluminum alloy plate 7. The second spring 62 is sleeved on the second adjusting rod 61, and both ends of the second spring 62 contact the connecting plate 60 and the side push box 63, respectively. A receiving groove 630 is provided on the side of the side push box 63 away from the second roller 64. An extension 610 is integrally formed at the end of the second adjusting rod 61. A spherical structure 611 is provided at the end of the extension 610. The spherical structure 611 is confined in the receiving groove 630. The diameter of the extension 610 is smaller than the diameter of the port of the receiving groove 630. The lateral limiting component 6 is used to provide a pushing force to the side of the thin aluminum alloy plate 7 close to the backing component 4, thereby reducing the pulling force at the moment the saw blade cuts in. When there is a protrusion or depression on the side of the thin aluminum alloy plate 7 close to the lateral limiting component 6, the second roller 64 can be made to fit as close as possible to the side of the thin aluminum alloy plate 7 by adjusting the second adjusting rod 61. The second adjusting rod 61 is restricted in the receiving groove 630 and the second adjusting rod 61 can rotate to a certain extent. It should be noted that when the second spring 62 is set between the connecting plate 60 and the side push box 63, the second spring 62 is always in a compressed state. When the first roller 525 in the clamping plate 520 contacts the top surface of the thin aluminum alloy plate 7, it can push the thin aluminum alloy plate 7 to move on the workpiece support table 3 from the left and right directions. At this time, the movement of the thin aluminum alloy plate 7 can drive the second roller 64 to rotate. The outer wall of the second roller 64 is provided with a rubber ring to increase the friction between the second roller 64 and the thin aluminum alloy plate 7, so that the second roller 64 can act on the side of the thin aluminum alloy plate 7 without slipping.

[0030] It should be noted that rotating the second adjusting rod 61 can adjust the distance between the side push box 63 and the connecting plate 60, so that the wider the thin aluminum alloy plate 7, the greater the force applied to the side of the thin aluminum alloy plate 7 by the lateral limiting component 6. In order to further improve the adaptability of the device, the lateral limiting component 6 includes a connecting plate 60, a second adjusting rod 61, a second spring 62, a side push box 63, and a second roller 64. The connecting plate 60 is fixed on the base 1 and symmetrically arranged along the cutting seam 10. The second adjusting rod 61 horizontally passes through the connecting plate 60 and is connected to the side push box 63. Several second rollers 64 are arranged on the side of the side push box 63 near the backing member 4. The second rollers 64 contact the side of the thin aluminum alloy plate 7. On the side of the side push box 63 away from the second roller 64, a receiving groove 630 is provided. The end of the second adjusting rod 61 is integrally formed with an extension 610. The end of the extension 610 is provided with a spherical structure 611. The spherical structure 611 is confined in the receiving groove 630. The diameter of the extension 610 is smaller than the diameter of the port of the receiving groove 630. The second spring 62 is provided in the receiving groove 630 and one end abuts against the spherical structure 611 (not shown in the figure). By rotating the second adjusting rod 61, the side of the thin aluminum alloy plate 7 of different widths can be pushed. At the same time, the second spring 62 is confined in the receiving groove 630, which can greatly avoid interference from the external environment, thereby increasing the adaptability and service life of the device.

[0031] Example 2 like Figure 9 As shown, this invention provides an aluminum alloy automotive parts cutting device. A lever 527 is provided on the tilting section 524. One end of the lever 527 contacts the lateral limiting component 6. When the clamping component 52 is tilted until the first roller 525 contacts the thin aluminum alloy plate 7, the lever 527 presses down on the lateral limiting component 6 until it disengages from the side of the thin aluminum alloy plate 7. That is, when switching the state of the clamping component 5, when the first roller 525 contacts the top surface of the thin aluminum alloy plate 7, the lever 527 can drive the side push box 63 to deflect, thereby making the movement of the thin aluminum alloy plate 7 more convenient.

[0032] Furthermore, since the lateral limiting component 6 always provides a backward pushing force to the thin aluminum alloy plate 7, the friction between the second roller 64 and the thin aluminum alloy plate 7 is increased. When the thin aluminum alloy plate 7 needs to be pulled on the workpiece support table 3, the thin aluminum alloy plate 7 is also always squeezed between the backing component 4 and the lateral limiting component 6. Preferably, an elastic support table surface (not shown in the figure) is provided at the bottom of the side push box 63. When the actuating lever 527 moves the side push box 63 downward near the thin aluminum alloy plate 7, At this time, the lateral pushing force of the lateral limiting component 6 on the thin aluminum alloy plate 7 is released, making it easier to release and move the thin aluminum alloy plate 7. After the position of the thin aluminum alloy plate 7 is adjusted, the flip handle 526 is released, and the first roller 525 is released from contact with the thin aluminum alloy plate 7. At this time, the pressing component 5 presses the thin aluminum alloy plate 7 from the top surface, and the toggle rod 527 moves upward. At this time, the support table returns to its original shape due to its own elasticity, thereby lifting the side push box 63 to the side that contacts the thin aluminum alloy plate 7.

[0033] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
