Description

Technical Field

[0001] This utility model relates to the field of precision processing technology, specifically to a metal sheet fixed-distance cutting device. Background Technology

[0002] In the field of metal processing, thin metal sheets are widely used in industries such as electronics, automobiles, and instrumentation due to their lightweight and thinness. To meet the assembly requirements of different scenarios, thin metal sheets need to be cut at fixed intervals to obtain workpieces of specific dimensions. Traditional cutting devices mostly use hydraulic cylinders to drive the cutter for cutting operations. Although they can achieve basic cutting functions, the instantaneous impact force on the thin metal sheet when the cutter moves downward is relatively large, which can easily cause deformation problems such as bending and wrinkling at the cut edges, seriously affecting the workpiece accuracy. At the same time, the fixed-distance conveying mechanism of existing devices mostly relies on baffles or simple pushing structures. During the conveying process, the thin metal sheet is prone to displacement due to unstable positioning, resulting in large cutting dimensional errors and making it difficult to meet the requirements of high-precision processing. In addition, existing thin metal sheet cutting devices lack effective auxiliary fixing structures. During cutting, the thin metal sheet is prone to displacement due to vibration, further exacerbating the instability of cutting quality. Moreover, the cut workpieces often need to be manually removed, which not only increases the number of operation steps but also reduces continuous production efficiency, making it difficult to adapt to the needs of automated processing.

[0033] Example 1:

[0034] The main structure of this embodiment is as follows: Figures 1-3 As shown, it includes a worktable (1), a cutter (4), a mounting bracket, and a conveyor assembly;

[0035] The mounting bracket is located at the bottom of one end of the workbench (1), and its top extends above the workbench (1) and is slidably connected to the workbench (1) in the vertical direction. The bottom end of the mounting bracket is provided with a drive component for driving the mounting bracket to move up and down repeatedly in the use state.

[0036] The cutter (4) is mounted on the top of the mounting frame and located above the workbench (1). The side of the cutter (4) is provided with a pressing component that is connected to the mounting frame and presses and fixes the metal sheet in use. The number of pressing components is at least one.

[0037] The conveying assembly is located at the bottom of the other end of the workbench (1) and in the middle of the workbench (1). The top of the conveying assembly extends to the upper surface of the workbench (1), and the conveying assembly is provided with a limiting component that limits the position of the metal sheet in the use state.

[0038] The specific implementation process is as follows: the metal sheet to be cut is placed on the upper surface of the worktable (1), and the initial position of the sheet is adjusted by the limiting component so that its edge is aligned with the limiting structure; the drive component and the conveying component are started, and the conveying component drives the metal sheet to move along the length direction of the worktable (1) towards the cutter (4) through the limiting component. The moving distance is controlled by the setting parameters of the conveying component (to achieve fixed distance); the drive component drives the mounting frame to slide down vertically, and the mounting frame simultaneously drives the cutter (4) and the pressing component to move down. The pressing component first contacts the metal sheet and presses the sheet with elastic force; the cutter (4) continues to move down to complete the cutting of the metal sheet; the drive component drives the mounting frame to move up and reset, the pressing component disengages from the sheet, and the conveying component drives the remaining sheet to move a set distance again. The above process is repeated to achieve continuous fixed-distance cutting.

[0039] Example 2:

[0040] This embodiment further defines the structure of the mounting bracket based on the above embodiments, such as... Figures 1-3 As shown, the mounting frame includes a connecting seat (2) and a support plate (3); the support plate (3) is U-shaped, and is located at the bottom of one end of the workbench (1) with its top extending above the workbench (1) and slidingly connected to the workbench (1) in the vertical direction; there are two connecting seats (2), and both connecting seats (2) are installed on the top of the support plate (3). The U-shaped support plate (3) spans the bottom of one end of the workbench (1), and its top extends above the workbench (1) and slidesly connected to the workbench (1), which not only ensures the structural stability of the mounting frame, but also provides a stable mounting carrier for the cutter (4) and the pressing assembly; the double connecting seats (2) are symmetrically installed on the top of the support plate (3) to fix the fixing shell (10) of the cutter (4) and the pressing assembly, ensuring the uniform transmission of force during cutting.

[0041] The specific implementation process is as follows: the bottom end of the U-shaped structure of the support plate (3) is fixed to the bottom of one end of the workbench (1), and the top end extends through the reserved gap of the workbench (1) to the top of the table surface. It is vertically slidably connected to the workbench (1) through the slide rail. Two connecting seats (2) are installed in parallel on both sides of the top end of the support plate (3). The two ends of the cutter (4) are fixed to the two connecting seats (2) respectively. The fixing shell (10) of the pressing component is installed between the two connecting seats (2). When the driving component drives the support plate (3) to slide up and down, the connecting seats (2) drive the cutter (4) and the pressing component to move synchronously. The U-shaped structure ensures that the support plate (3) is subjected to balanced force and avoids the cutter (4) from tilting. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0042] Example 3:

[0043] This embodiment further defines the structure of the driving component based on the above embodiments, such as... Figures 1-3 As shown, the drive assembly includes a first motor (5), a turntable (6), a connecting column (14), and a connecting rod (18). The first motor (5) is located below the worktable (1). The turntable (6) is mounted on the output shaft of the first motor (5). The connecting column (14) is located on the side of the turntable (6) and is arranged near the edge of the turntable (6). The connecting rod (18) is rotatably mounted in the connecting column (14) and rotatably connected to the support plate (3). The first motor (5) drives the turntable (6) to rotate, and the connecting column (14) on the edge of the turntable (6) performs a circular motion. The circular motion is converted into a linear reciprocating motion of the support plate (3) through the connecting rod (18). Compared with hydraulic cylinder drive, this structure has lower cost and more stable motion rhythm, and can accurately control the cutting frequency and stroke of the cutter (4).

[0044] The specific implementation process is as follows: the first motor (5) is fixed on the bracket below the workbench (1), and the output shaft is connected to the central axis of the turntable (6); the connecting column (14) is vertically installed on the side edge of the turntable (6), one end of the connecting rod (18) is rotatably connected to the connecting column (14) through a bearing, and the other end is rotatably connected to the bottom end of the support plate (3); the first motor (5) is started, the turntable (6) rotates and drives the connecting column (14) to rotate around the center of the turntable (6), and the connecting rod (18) pushes and pulls the support plate (3) accordingly, so that the support plate (3) slides vertically along the workbench (1), realizing the up and down reciprocating cutting action of the cutter (4). The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0045] Example 4:

[0046] This embodiment further defines the structure of the pressing component based on the above embodiments, such as... Figure 5 As shown, the pressing assembly includes a connecting shell (7), a fixed shell (10), and a spring (17). The fixed shell (10) is installed between two connecting seats (2) and located on the side of the cutter (4). The connecting shell (7) is sleeved on the outside of the fixed shell (10) and is in close contact with the side of the cutter (4). The spring (17) is located on the inside between the connecting shell (7) and the fixed shell (10), and its two ends are respectively connected to the inside of the connecting shell (7) and the fixed shell (10). The fixed shell (10) is fixed to the connecting seat (2), and the connecting shell (7) is sleeved on the outside of the fixed shell (10) and can slide relative to it. The spring (17) provides elastic pressure between the two. During cutting, the connecting shell (7) contacts the sheet first and moves down with the cutter (4). The spring (17) is compressed to generate a reaction force, pressing the sheet tightly on the worktable (1) to prevent the sheet from warping or shifting during cutting.

[0047] The specific implementation process is as follows: the fixed shell (10) is horizontally fixed between the two connecting seats (2), located on the feeding side or both sides of the cutter (4); the inner side of the connecting shell (7) is sleeved on the outer side of the fixed shell (10), and the bottom is slightly lower than the blade of the cutter (4); the spring (17) is evenly distributed between the fixed shell (10) and the connecting shell (7), and the two ends are fixed to the inner sidewalls of both respectively; when the cutter (4) moves downward, the connecting shell (7) first contacts the metal sheet, and the cutter (4) continues to move downward, driving the fixed shell (10) to compress the spring (17). The elastic force of the spring (17) makes the connecting shell (7) press the sheet tightly until the cutter (4) completes the cutting; when the cutter (4) moves upward, the spring (17) returns to its original position, and the connecting shell (7) disengages from the sheet. The other parts of this embodiment are the same as those in the above embodiment, and will not be repeated.

[0048] Example 5:

[0049] This embodiment further defines the structure of the pressing component based on the above embodiments, such as... Figure 5 As shown, the pressing assembly also includes a guide post and a guide hole. The guide post is located at the bottom inner side of the fixed shell (10), and the guide hole is located at the top inner side of the connecting shell (7). The guide post and the guide hole are slidably engaged, and the spring (17) is sleeved on the outside of the guide post. The added engagement structure of the guide post and the guide hole restricts the relative movement direction between the connecting shell (7) and the fixed shell (10), prevents the spring (17) from lateral tilting or twisting during compression / extension, ensures that the pressure of the connecting shell (7) on the metal sheet is evenly distributed, and further improves the pressing stability.

[0050] The specific implementation process is as follows:

[0051] The guide post is vertically fixed to the bottom inner side of the fixed shell (10), and the guide hole is opened at the top inner side of the connecting shell (7). The axes of the two are coincident and have a clearance fit. The spring (17) is sleeved on the outside of the guide post, and its two ends are connected to the fixed shell (10) and the connecting shell (7) respectively. During cutting, the connecting shell (7) moves down with the cutter (4), and the guide hole slides along the guide post, which restricts the lateral displacement of the connecting shell (7) and ensures that the spring (17) is only compressed axially. The bottom of the connecting shell (7) is flat and pressed on the sheet. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0052] Example 6:

[0053] This embodiment further defines the structure of the conveying component based on the above embodiments, such as... Figures 1-4As shown, the conveying assembly includes a mounting shell (12), a second motor (13), a lead screw (15), and a slider (16). The mounting shell (12) is located at the center below the other end of the worktable (1) and is arranged along the length of the worktable (1). The lead screw (15) is rotatably mounted inside the mounting shell (12). The second motor (13) is located at one end of the mounting shell (12) and is connected to the lead screw (15) for transmission. The slider (16) is slidably mounted inside the mounting shell (12) and threadedly engaged with the lead screw (15). The top of the slider (16) extends to the top of the worktable (1) and is connected to the limiting assembly. The second motor (13) drives the lead screw (15) to rotate. The slider (16) slides along the length of the mounting shell (12) (i.e., the length of the worktable (1)) through the threaded engagement with the lead screw (15). The sliding distance can be precisely controlled by the rotation speed and rotation angle of the second motor (13), thereby realizing the fixed-distance feeding of the metal sheet.

[0054] The specific implementation process is as follows: the mounting shell (12) is fixed below the other end of the workbench (1) and arranged along the length of the workbench (1). The screw rod (15) is rotated inside; the second motor (13) is installed at one end of the mounting shell (12), and the output shaft is connected to the screw rod (15) through a coupling; the slider (16) is sleeved on the screw rod (15) and threaded with the screw rod (15). The top of the slider (16) passes through the strip groove of the workbench (1) and is connected to the limiting component; the second motor (13) is started, the screw rod (15) rotates and drives the slider (16) to slide along the mounting shell (12). The slider (16) pushes the metal sheet to move towards the cutter (4) through the limiting component. The moving distance is controlled by the preset parameters of the second motor (13). Other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0055] Example 7:

[0056] This embodiment further defines the structure of the limiting component based on the above embodiments, such as... Figure 5 As shown, the limiting assembly includes a push plate (8), a limiting plate (9), and an extension rod (11); the extension rod (11) is installed on the top of the slider (16); the push plate (8) is installed on one end of the extension rod (11) and is slidably connected to the upper end face of the worktable (1) along the length of the worktable; there are two limiting plates (9), both of which are set on the side of the push plate (8) and bolted to the push plate (8). The extension rod (11) transmits the power of the slider (16) to the push plate (8), and the push plate (8) pushes the sheet forward when it slides along the worktable (1); the two limiting plates (9) are symmetrically arranged on the side of the push plate (8) to form a channel that matches the width of the sheet, restricting the lateral offset of the sheet and ensuring accurate conveying direction.

[0057] The specific implementation process is as follows: the extension rod (11) is vertically fixed to the top of the slider (16), and the other end is connected to the bottom of the push plate (8). The bottom surface of the push plate (8) is in contact with the upper surface of the worktable (1). Two limiting plates (9) are respectively installed on both sides of the push plate (8) by bolts to form a gap that matches the width of the metal sheet. When the conveying assembly is working, the slider (16) drives the push plate (8) to slide along the length direction of the worktable (1) through the extension rod (11). The front end of the push plate (8) pushes the metal sheet, and the limiting plates (9) block the two sides of the sheet to prevent the sheet from tilting during the conveying process. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0058] Example 8:

[0059] This embodiment further defines the structure of the limiting component based on the above embodiments, such as... Figure 5 As shown, the top of the push plate (8) is provided with multiple threaded grooves (20), which are arranged at equal intervals. The top of the limiting plate (9) extends to the top of the push plate (8). The top of the limiting plate (9) is provided with a waist-shaped hole (19) that mates with the threaded grooves (20). Bolts pass through the waist-shaped hole (19) and connect with the threaded grooves (20) to fix the limiting plate (9). The multiple threaded grooves (20) on the top of the push plate (8) are distributed at equal intervals. The waist-shaped hole (19) on the top of the limiting plate (9) can be adjusted along the length direction. Bolts pass through the waist-shaped hole (19) and connect with the threaded grooves (20) at different positions, which can change the distance between the two limiting plates (9) to adapt to metal sheets of different widths and improve the versatility of the device.

[0060] The specific implementation process is as follows: according to the width of the metal sheet to be cut, loosen the bolt at the top of the limiting plate (9); slide the limiting plate (9) along the width direction of the push plate (8) so that the distance between the two limiting plates (9) matches the width of the sheet, at which time the waist-shaped hole (19) slides relative to the bolt; after the adjustment is completed, tighten the bolt through the waist-shaped hole (19) into the corresponding threaded groove (20) to fix the position of the limiting plate (9) and ensure that the sheet does not undergo lateral displacement during conveying and cutting. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0061] Example 9:

[0062] Based on the above embodiments, this embodiment further defines the structure of the workbench (1), such as... Figure 5As shown, a material discharge port is provided on the upper surface of the workbench (1) and directly below the cutter (4). A collection box is provided below the material discharge port, and the collection box is detachably connected to the bottom of the workbench (1). By setting a material discharge port directly below the cutter (4) on the workbench (1) and configuring a detachable collection box below it, the cut metal sheet is allowed to fall directly into the collection box through the material discharge port by gravity, avoiding the accumulation of sheet on the workbench (1) and affecting subsequent cutting. At the same time, it simplifies the material feeding process and improves work efficiency.

[0063] The specific implementation process is as follows: the material discharge port is located on the upper surface of the workbench (1), directly below the cutter (4), and its size is slightly larger than the maximum cutting size; the collection box is installed at the bottom of the workbench (1) by a buckle or slide rail, with its opening facing the material discharge port; after cutting, the cutter (4) moves upward, and the conveying component drives the remaining sheet to continue moving, and the cut sheet falls from the material discharge port into the collection box under the action of gravity; when the collection box is full, the collection box can be directly disassembled to remove the sheet, and then reinstalled. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.
