Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically a stable cutting device. Background Technology

[0002] Sheet metalworking is a comprehensive cold-working process for thin metal sheets, including shearing, splicing, and forming. Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal work are called sheet metal parts. The term "sheet metal part" generally varies across different industries, but it is often used in assembly contexts. Sheet metal parts are products manufactured using sheet metal processes, and they are indispensable in our daily lives. For example, the internal structure of a camera front end is made from sheet metal parts. However, cutting devices are typically used in the production and processing of sheet metal parts.

[0003] Currently, sheet metal cutting equipment used in the market typically moves the sheet metal part during cutting. However, during this movement, it is easy for the cutting tool to be inaccurate, resulting in cutting deviations and scrapping of the sheet metal part.

[0004] To address the aforementioned technical problems, numerous patents have been proposed in the prior art. One such patent is a Chinese invention patent with application number 202222635155.5 and authorization publication number CN218395519U, entitled "A Sheet Metal Part Cutting Device." This patent discloses a sheet metal part cutting device, including a base plate, a support frame, a cutting blade, a moving assembly, and a cutting assembly. By matching the support frame lifting block and the lifting screw, the cutting blade can be quickly adjusted up and down to adjust the cutting depth, which can largely meet the cutting requirements of production. At the same time, the L-shaped positioning column, positioning block, and positioning hole are matched.

[0005] The aforementioned patent enables precise positioning of the cutting position of the cutting blade, ensuring the accuracy of the cutting position. It is known that springs are unstable. In existing technologies, including the aforementioned patent, an auxiliary spring is used to pull an L-shaped rod to slide. The sheet metal part is fixed through the cooperation between the L-shaped rod and the auxiliary spring. However, during the cutting operation, a large cutting force will cut the sheet metal part. Therefore, relying solely on the auxiliary spring for fixing is clearly insufficient to meet the requirements for fixing the sheet metal part, resulting in deviations during the cutting process and affecting the cutting quality. Summary of the Invention

[0006] The purpose of this invention is to provide a stable cutting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stable cutting device, comprising a work frame and a support plate slidably connected to the work frame, a cutting mechanism mounted on the support plate, a processing cavity formed on the work frame, a driving component for driving the support plate to slide vertically on the work frame, a clamping assembly for clamping sheet metal parts inside the processing cavity, and a triggering assembly between the support plate and the processing cavity; when the driving component drives the support plate to slide downward so that the cutting mechanism performs cutting operations on the sheet metal parts, the clamping assembly is driven by the transmission assembly to fix the sheet metal parts.

[0012] Furthermore, the elastic part includes a scissor lifting unit installed between the top plate and the work frame. Limiting blocks are provided on both sides of the bottom of the scissor lifting unit. The two limiting blocks are slidably connected to both sides of the work frame. A storage spring is provided between the limiting blocks and the work frame.

[0013] Furthermore, the work frame is also provided with an installation frame, and the installation frame is provided with an ejection assembly. The ejection assembly includes an ejection plate slidably connected to the installation frame, and a linkage assembly is provided between the support plate and the ejection plate.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-8 The present invention provides a technical solution: a stable cutting device, including a work frame 1 and a support plate 2 slidably connected to the work frame 1. A cutting mechanism 4 is installed on the support plate 2. A processing cavity 11 is opened on the work frame 1. A driving member 3 for driving the support plate 2 to slide vertically is provided on the work frame 1. A clamping assembly 5 for clamping sheet metal parts is provided inside the processing cavity 11. A triggering assembly 6 is provided between the support plate 2 and the processing cavity 11. When the driving member 3 drives the support plate 2 to slide downward so that the cutting mechanism 4 performs cutting operations on the sheet metal parts, the clamping assembly 5 is driven by the transmission assembly to fix the sheet metal parts.

[0030] Specifically, the stable cutting device includes a work frame 1, as referenced. Figure 1 , Figure 2 The cutting device includes multiple sets of support columns at the bottom of the work frame 1, each with an anti-slip pad to improve stability during operation. More specifically, an adjustable moving component is provided at the bottom of the work frame 1, allowing for automatic switching between fixed and movable modes to enhance flexibility and meet work requirements. A support plate 2 is slidably connected to the work frame 1, and a cutting mechanism 4 is mounted on the support plate 2. The up-and-down sliding of the support plate 2 drives the cutting mechanism 4 to slide up and down, improving the practicality of the cutting device. The cutting mechanism 4 includes a drive motor with a cutting blade at its output. A track assembly is also provided on the support plate 2. The cutting mechanism 4 is slidably connected to the support plate 2 via a mounting frame 9, enabling it to slide along the X and Y axes on the support plate 2. This allows it to perform cutting operations on sheet metal parts on the work frame 1 according to work needs, further enhancing the practicality of the cutting device. The work frame 1 has a processing cavity 11 for facilitating the positioning of sheet metal parts and improving their stability during cutting. The work frame 1 is equipped with a drive component 3 for vertically sliding the support plate 2. Specifically, the drive component 3 can be a servo cylinder, hydraulic rod, or motor drive, as long as it enables the support plate 2 to slide vertically on the work frame 1. Inside the processing cavity 11 is a clamping assembly 5 for holding the sheet metal parts, which improves the stability of the sheet metal parts during cutting, thereby improving the cutting quality and meeting work requirements. A trigger assembly 6 is located between the support plate 2 and the processing cavity 11, which can adjust the state of the clamping assembly 5 according to work needs, enabling the clamping assembly 5 to open and close without the need for an additional drive source. This facilitates the installation and removal of sheet metal parts and improves their stability during cutting.

[0031] Specifically, when sheet metal parts need to be cut, the sheet metal parts to be processed are placed inside the processing cavity 11. Then, the drive component 3 drives the support plate 2 to slide downwards, which in turn drives the cutting mechanism 4 to slide downwards, preparing for the sheet metal part to be cut. Simultaneously, as the support plate 2 slides downwards, driving the cutting mechanism 4 to prepare for the sheet metal part cutting operation, the trigger component 6 drives the clamping component 5 to move closer to one side of the sheet metal part, fixing the sheet metal part. At this moment, when the cutting mechanism 4 is cutting the sheet metal part, the fixing effect of the clamping component 5 improves the stability of the sheet metal part during cutting, thus improving the cutting quality. After the sheet metal part cutting operation is completed, the drive component 3 drives the support plate 2 to slide upwards. When the support plate 2 slides upwards, the trigger component 6 drives the clamping component 5 to slide away from the sheet metal part, unlocking the sheet metal part, thereby enabling rapid disassembly of the sheet metal part to meet work requirements. Therefore, this application can improve the stability of sheet metal parts during cutting operations, thereby improving the cutting quality. It can also realize the automatic unlocking of the clamping component 5, which facilitates the disassembly of sheet metal parts, further improving the practicality of the cutting device and meeting work needs.

[0032] In the embodiments provided by the present invention, reference is made to Figures 4-7 The clamping mechanism includes two opposing clamping plates 501 slidably connected inside the processing cavity 11. Specifically, the clamping plates 501 are L-shaped plates, and each clamping plate 501 is slidably connected to the processing cavity 11 via a bearing block 502. A bidirectional lead screw 503 is rotatably connected to the work frame 1, and each bearing block 502 is threaded to both ends of the bidirectional lead screw 503. When the bearing plate 2 slides downward, the trigger assembly 6 drives the bidirectional lead screw 503 to rotate in the forward direction. When the bidirectional lead screw 503 rotates in the forward direction, it drives the bearing blocks 502 on both sides to move closer together, fixing the sheet metal part. When the bearing plate 2 slides upward, the trigger assembly 6 drives the bidirectional lead screw 503 to rotate in the reverse direction. When the bidirectional lead screw 503 rotates in the reverse direction, it drives the bearing blocks 502 on both sides to move away from each other, unlocking the sheet metal part.

[0033] In another embodiment of the present invention, each clamping plate 501 is slidably connected to the processing cavity 11 via a bearing block 502. Specifically, a limiting groove is provided on the bearing block 502, and a connecting block is fixedly connected to the bottom of each clamping plate 501. Each connecting block is slidably connected in the limiting groove, and a buffer spring is provided between each limiting groove and the connecting block, which can play a certain buffering effect, thus further improving the applicability of the clamping mechanism. Specifically, during operation, when the bidirectional lead screw 503 rotates in the forward direction, it drives the bearing block 502 to slide. At this moment, the bearing block 502 drives the clamping plate 501 to slide towards the sheet metal part. After the clamping plates 501 on both sides abut against the sheet metal part, the cutting mechanism 4 is still not in contact with the sheet metal part. Therefore, the driving component 3 needs to continue to drive the bearing plate 2 to slide downward. However, at this moment, while the bidirectional lead screw 503 is rotating and driving the bearing block 502 to slide, the clamping plate 501 still cannot slide, which will pull the buffer spring. The elastic force of the buffer spring is used to fix the sheet metal part, avoiding stiffness in movement and further improving the practicality of the cutting mechanism 4 to meet the work requirements. It should be noted that the elastic coefficient of the buffer spring is large enough, so using the buffer spring to fix the sheet metal part is sufficient to fix the sheet metal part, which can also reduce the wobbling of the sheet metal part during the cutting operation.

[0034] In the embodiments provided by the present invention, reference is made to Figures 4-7 The triggering component 6 includes a triggering rack 601 slidably connected to the work frame 1, and spur gears 602 are provided on both ends of the bidirectional lead screw 503. The triggering rack 601 meshes with the spur gears 602. The bearing plate 2 intermittently abuts against the triggering rack 601. When the driving component 3 drives the bearing plate 2 to slide downward to a predetermined position, the bearing plate 2 abuts against the triggering rack 601. Therefore, in actual use, the drive component 3 drives the support plate 2 to slide downward, which in turn drives the cutting mechanism 4 to slide downward. After the support plate 2 slides downward to a certain position, it will abut against the trigger rack 601. After abutting against the trigger rack 601, the support plate 2 continues to slide downward, which will drive the trigger rack 601 to slide downward. When the trigger rack 601 slides downward, it can drive the spur gear 602 to rotate. The rotation of the spur gear 602 drives the double-acting screw 503 to rotate. When the double-acting screw 503 rotates in the forward direction, it can drive the support blocks 502 on both sides to move closer to each other and fix the sheet metal parts. Then, when the cutting mechanism 4 is used to cut the sheet metal parts, it can improve the stability of the sheet metal parts during processing and meet the work requirements.

[0035] In the embodiments provided by the present invention, a reset component is provided between the trigger rack 601 and the work frame 1. The reset component includes a mounting plate 604 fixedly connected to the trigger rack 601, and a reset spring 605 is provided between the mounting plate 604 and the work frame 1. Specifically, a vertical groove is provided on the work frame 1, wherein the trigger rack 601 and the mounting plate 604 on the trigger rack 601 are slidably connected and mounted in the vertical groove, and the reset spring 605 is installed between the vertical groove and the mounting plate 604. When the bearing plate 2 drives the trigger rack 601 to slide downward, This will compress the return spring 605; after the sheet metal cutting operation is completed, the bearing plate 2 drives the cutting mechanism 4 to slide upward. When the trigger rack 601 is not compressed, the return spring 605 drives the rack to slide upward during the process of restoring its elastic deformation. When the bearing plate 2 slides upward, it can drive the bidirectional lead screw 503 to rotate in the opposite direction through the trigger component 6. When the bidirectional lead screw 503 rotates in the opposite direction, it can drive the bearing blocks 502 on both sides to move away from each other, and then drive the clamping plates 501 to move away from each other, thus unlocking the sheet metal.

[0036] In the embodiments provided by the present invention, reference is made to Figures 4-7 The work frame 1 is equipped with an ejector assembly 8. This ejector mechanism allows the sheet metal parts located inside the processing cavity 11 to be ejected after the cutting operation, facilitating the unloading of the sheet metal parts. The ejector assembly 8 includes an ejector plate 801 slidably connected inside the work frame 1. Multiple ejector rods 805 are mounted on the ejector plate 801 and slidably connected to the work frame 1. Multiple positioning boxes 603 are fixedly connected to the ejector plate 801. A trigger rack 601 intermittently abuts against the ejector plate 801 through the positioning boxes 603. An elastic section is provided between the ejector plate 801 and the work frame 1. Therefore, in actual use, the drive component 3 drives the support plate 2 to slide downwards, thereby facilitating the cutting process. Mechanism 4 slides downwards. After the support plate 2 slides down to a certain position, it abuts against the trigger rack 601. During the downward sliding stroke of the support plate 2 after abutting against the trigger rack 601, it drives the trigger rack 601 to slide downwards. When the trigger rack 601 slides downwards, it is inserted into the positioning box 603, which in turn drives the ejector plate 801 to slide downwards. When the ejector plate 801 continues to slide downwards, it drives the elastic part to deform, causing the elastic part to store force. Therefore, after the sheet metal part cutting operation is completed, the support plate 2 drives the cutting mechanism 4 to slide upwards. When the trigger rack 601 is not subjected to compression, the elastic part restores its elastic deformation, driving the support plate 2 to slide upwards. This drives multiple sets of ejector rods 805 to slide upwards, and the ejector rods 805 push the sheet metal part out of the processing cavity 11, facilitating the unloading of the sheet metal part.

[0037] In the embodiments provided by the present invention, the elastic part includes a scissor lifting unit 802 installed between the top plate 801 and the work frame 1. Limiting blocks 803 are provided on both sides of the bottom of the scissor lifting unit 802. The two limiting blocks 803 are slidably connected to both sides of the work frame 1. A storage spring 804 is provided between the limiting blocks 803 and the work frame 1. Specifically, a transverse groove is provided inside the processing frame, wherein the limiting blocks 803 are slidably connected in the transverse groove, and the storage spring 804 is installed between the transverse groove and the limiting blocks 803, thereby improving the stability of the elastic part during use and achieving good performance.

[0038] In the embodiments provided by the present invention, specifically, refer to Figure 4 as well as Figure 7 A mounting frame 9 is also provided on the work frame 1, and an ejector assembly 10 is provided on the mounting frame 9. By providing the ejector assembly 10, the sheet metal parts ejected by the ejector rod 805 can be pushed to a predetermined position, further improving the working efficiency of the cutting device. The ejector assembly 10 includes an ejector plate 1001 slidably connected to the mounting frame 9, and a linkage assembly is provided between the support plate 2 and the ejector plate 1001. When the support plate 2 slides upward, the linkage assembly drives the ejector plate 1001 to slide closer to the inside of the work frame 1, which facilitates the ejection of the sheet metal parts on the work frame 1. At the same time, this operation is also generated by the drive component 3 driving the support plate 2 to slide downward and upward, without the need for an additional drive source, further improving the practicality of the cutting device. At the same time, when the support plate 2 slides downward, the linkage assembly drives the ejector plate 1001 to slide away from the inside of the work frame 1. At this time, the ejector plate 1001 is away from the inside of the processing frame, so there is no movement stiffness when the support plate 2 slides downward, which meets the working needs and has a good working effect.

[0039] In the embodiments provided by the present invention, the linkage component includes a linkage rod 1003 rotatably connected to the mounting frame 9, a long gear 1004 mounted on the linkage rod 1003, a toothed plate 1002 slidably connected to the mounting frame 9 and fixedly connected to the ejector plate 1001, the toothed plate 1002 meshing with the long gear 1004, a positioning spring 1005 provided between the toothed plate 1002 and the mounting frame 9, and an adjustment unit 12 provided between the bearing plate 2 and the mounting frame 9 to drive the ejector plate 1001 to slide. (Reference) Figure 8The adjustment unit 12 includes an adjustment rack 1201 vertically slidably connected to the work frame 1, which meshes with a long gear 1004. An adjustment rod 1202 is fixedly connected to the support plate 2. An adjustment groove 1203 is provided on the adjustment rack 1201, and the adjustment rod 1202 is slidably connected in the adjustment groove 1203. Because the adjustment rod 1202 slides inside the adjustment groove 1203, it provides a certain buffering effect. For example, when the support plate 2 slides upward, it can only drive the adjustment rack 1201 to slide upward after sliding to the end of the adjustment groove 1203. During the sliding process of the adjustment rod 1202 inside the adjustment groove 1203, the ejector assembly 8 can just push the sheet metal part to the predetermined position, and then the ejector assembly 10 pushes the sheet metal part out, resulting in good performance. Specifically, in actual use, the drive component 3 drives the support plate 2 to slide downwards. The support plate 2 drives the adjusting rack 1201 to slide downwards via the adjusting rod 1202. When the adjusting rack 1201 slides downwards, it can drive the long gear 1004 to rotate counterclockwise, which in turn drives the linkage rod 1003 to rotate counterclockwise. When the linkage rod 1003 rotates counterclockwise, it can drive the toothed plate 1002 to slide away from the processing frame, so that the ejector plate 1001 moves away from the processing frame without causing stiffness in the movement, thus meeting the work requirements. After the sheet metal part cutting operation is completed, the bearing plate 2 drives the cutting mechanism 4 to slide upward. The adjusting rod 1202 drives the adjusting rack 1201 to slide upward. When the adjusting rack 1201 slides upward, it drives the long gear 1004 to rotate clockwise, which in turn drives the toothed plate 1002 to slide closer to the inside of the work frame 1. As the adjusting rack 1201 continues to slide upward, it drives the ejector plate 1001 to slide continuously, ejecting the cut sheet metal part to meet the work requirements. The positioning spring 1005 is provided to reset the toothed plate 1002 when it is not under the action of the adjusting unit 12, which is convenient for subsequent use.

[0040] In the embodiments provided by the present invention, multiple sets of limiting telescopic rods 7 are provided between the work frame 1 and the bearing plate 2, which can further improve the stability of the bearing plate 2 when it slides.

[0041] Working principle: When it is necessary to cut sheet metal parts, the sheet metal parts to be processed are placed inside the processing cavity 11. Then, the drive component 3 drives the support plate 2 to slide downward, which in turn drives the cutting mechanism 4 to slide downward, in preparation for cutting the sheet metal parts.

[0042] During sheet metal processing:

[0043] The drive component 3 drives the support plate 2 to slide downward, which in turn drives the cutting mechanism 4 to slide downward. After the support plate 2 slides down to a certain position, it will abut against the trigger rack 601. After abutting against the trigger rack 601, the support plate 2 continues to slide downward, which will drive the trigger rack 601 to slide downward. When the trigger rack 601 slides downward, it can drive the spur gear 602 to rotate. The rotation of the spur gear 602 drives the double-acting screw 503 to rotate. When the double-acting screw 503 rotates in the positive direction, it can drive the support blocks 502 on both sides to move closer to each other and fix the sheet metal part. Then, when the cutting mechanism 4 is used to cut the sheet metal part, it can improve the stability of the sheet metal part during processing and meet the work requirements.

[0044] At the same time, after the support plate 2 slides down to a certain position, it will abut against the trigger rack 601. After abutting against the trigger rack 601, during the downward sliding stroke of the support plate 2, the trigger rack 601 will be driven to slide down. When the trigger rack 601 slides down, it can drive the ejector plate 801 to slide down by inserting into the positioning box 603. When the ejector plate 801 continues to slide down, it will cause the elastic part to deform, so that the elastic part stores force.

[0045] At the same time, when the support plate 2 slides downward, the support plate 2 drives the adjusting rack 1201 to slide downward through the adjusting rod 1202. When the adjusting rack 1201 slides downward, it can drive the long gear 1004 to rotate counterclockwise, which in turn can drive the linkage rod 1003 to rotate counterclockwise. When the linkage rod 1003 rotates counterclockwise, it can drive the toothed plate 1002 to slide away from the processing frame, so that the ejector plate 1001 moves away from the processing frame without causing movement stiffness, thus meeting the work requirements.

[0046] After the sheet metal parts are cut:

[0047] The drive component 3 drives the bearing plate 2 to slide the cutting mechanism 4 upward. When the trigger rack 601 is not compressed, the return spring 605 drives the rack to slide upward during the process of restoring its elastic deformation. When the bearing plate 2 slides upward, the trigger component 6 can drive the bidirectional lead screw 503 to rotate in the opposite direction. When the bidirectional lead screw 503 rotates in the opposite direction, it can drive the bearing blocks 502 on both sides to move away from each other, and then drive the clamping plates 501 to move away from each other, thus unlocking the sheet metal part.

[0048] At the same time, when the bearing plate 2 drives the cutting mechanism 4 to slide upward, the elastic part drives the bearing plate 2 to slide upward during the process of restoring elastic deformation under the action of the trigger rack 601 without being squeezed. This drives multiple sets of ejector rods 805 to slide upward, and the ejector rods 805 push the sheet metal parts out of the processing cavity 11, which facilitates the unloading of the sheet metal parts.

[0049] Meanwhile, the carrier plate 2 drives the adjusting rack 1201 to slide upward via the adjusting rod 1202. When the adjusting rack 1201 slides upward, it drives the long gear 1004 to rotate clockwise, which in turn drives the gear plate 1002 to slide closer to the inside of the work frame 1. As the adjusting rack 1201 continues to slide upward, it drives the ejector plate 1001 to slide continuously, ejecting the cut sheet metal parts to meet the work requirements.

[0050] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
