Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing equipment, and specifically relates to a sheet metal cutting machine. Background Technology

[0002] In the process of creating models of ancient buildings, in order to approximate the original structure of the building as closely as possible, a large number of non-standard panels need to be made. For example, model parts such as screens, doors, partitions, and ceiling blocks all need to be cut from whole panels to form non-standard parts before carving. However, different non-standard parts have different lengths, widths, and thicknesses, and existing cutting devices are difficult to cut panels of various sizes in a fixed manner. Utility Model Content

[0003] In view of the above problems, this application provides a sheet metal cutting machine that can perform fixed cutting of sheets of various sizes.

[0004] This application provides a sheet metal cutting machine, which includes a platform, a cutting mechanism, and a clamping mechanism. The platform has a placement surface for supporting sheet metal along the direction of gravity; the cutting mechanism is located above the placement surface and is configured to move along a first direction and a second direction to cut the sheet metal, wherein the first direction, the second direction, and the direction of gravity are mutually perpendicular; the clamping mechanism is configured to move along the first direction, and there are two clamping mechanisms spaced apart along the first direction, with a first clamping gap between the two clamping mechanisms for clamping the sheet metal; wherein the clamping mechanism includes a sliding component and a pressing block, the first clamping gap is located between the sliding components of the two clamping mechanisms, the pressing block is adjustablely disposed within the sliding component along the direction of gravity, and a second clamping gap is formed between the pressing block and the placement surface for clamping the sheet metal.

[0005] Specifically, during the processing of the sheet material, the sheet material to be processed is placed on a support surface, with its thickness direction parallel to the direction of gravity. The distance between the two clamping mechanisms in the first direction is adjusted to restrict the movement of the sheet material. The movement of the sheet material in the direction of gravity is restricted by the pressure block and the support surface, and the movement of the sheet material in the second direction is restricted by the friction between the pressure block and the sheet material to fix it in place. At this time, the sheet material is cut by a cutting mechanism so that the dimensions of the sheet material in the second direction meet the length or width requirements of the non-standard sheet material to be processed.

[0006] The sheet material to be processed is then rotated so that the direction in which the sheet material meets the dimensions required for the non-standard sheet material to be formed is parallel to the first direction. Two clamping mechanisms are then used to restrict the movement of the sheet material in the first direction. The movement in the direction of gravity is restricted by the pressure block and the placement surface, and the movement in the second direction is restricted by the friction between the pressure block and the sheet material to fix it in place. The sheet material is then cut by a cutting mechanism so that its dimensions in the second direction meet the width or length requirements of the non-standard sheet material to be formed. This allows for the fixing and processing of sheets of different sizes.

[0007] In some embodiments, the sheet metal cutting machine further includes a first lead screw and a second lead screw, the first lead screw and the second lead screw having opposite directions of rotation, one end of the first lead screw and one end of the second lead screw being coaxially arranged and connected to each other; wherein, the sliding component of one of the two clamping mechanisms has a first threaded hole that is threadedly engaged with the first lead screw, and the sliding component of the other of the two clamping mechanisms has a second threaded hole that is threadedly engaged with the second lead screw.

[0008] In the above technical solution, the first lead screw and the second lead screw rotate in opposite directions, and the sliding component of one of the two clamping mechanisms has a first threaded hole that is threaded with the first lead screw, and the sliding component of the other of the two clamping mechanisms has a first threaded hole that is threaded with the second lead screw. Thus, by rotating the first lead screw and the second lead screw, the two sliding components can be driven to move closer to each other and further apart. The structure is simple and easy to implement.

[0009] In some embodiments, the sliding assembly includes a first mounting bracket and a second mounting bracket. The first mounting bracket is slidably disposed on the stage along the first direction; the second mounting bracket is disposed on the side of the first mounting bracket facing the other sliding assembly and is elastically connected to the first mounting bracket, and the first clamping gap is located between the second mounting brackets of the two clamping mechanisms.

[0010] In the above technical solution, the second mounting bracket is disposed on the side of the first mounting bracket facing the other sliding component and is elastically connected to the first mounting bracket. The first clamping gap is located between the second mounting brackets of the two clamping mechanisms. Therefore, when the second mounting bracket abuts against the plate in the first direction, the compressive deformation at the elastic connection between the second mounting bracket and the first mounting component gradually increases the compressive force transmitted from the first mounting bracket to the second mounting bracket, thereby gradually increasing the compressive force of the second mounting bracket on the plate and reducing the risk of the second mounting bracket damaging the plate during clamping.

[0011] In some embodiments, the sliding assembly further includes a first guide rod and a first spring. The first guide rod extends along the first direction, one end of the first guide rod is disposed on the side of the second mounting bracket facing the first mounting bracket, the first mounting bracket is provided with a first guide hole, and the other end of the first guide rod passes through the first guide hole; the first spring is sleeved outside the first guide hole, and both ends of the first spring are respectively connected to the first mounting bracket and the second mounting bracket, and the second mounting bracket moves toward the first mounting bracket to compress the first spring.

[0012] In the above technical solution, by setting a first guide rod and a first spring, on the one hand, the second mounting bracket can be elastically connected to the first mounting bracket; on the other hand, the movement of the second mounting bracket relative to the first mounting bracket in a direction that is at an angle to the first direction can be restricted, thereby enabling the second mounting bracket to more smoothly abut against the plate, so as to more stably restrict the movement of the plate in the first direction.

[0013] In some embodiments, the second mounting bracket includes a mounting body and a mounting plate. The first guide rod is disposed on the side of the mounting body facing the first mounting bracket; the mounting plate is disposed on the side of the mounting body away from the first mounting bracket, the thickness direction of the mounting plate is parallel to the direction of gravity, and the pressing block is connected to the mounting plate and located between the mounting plate and the placement surface.

[0014] In the above technical solution, the mounting plate is set to facilitate the setting of the pressure block, and the structure is simple and easy to implement.

[0015] In some embodiments, the sliding assembly further includes a guide block. The guide block is disposed on the side of the first mounting bracket facing the second mounting bracket, and the side of the guide block facing the pressing block is provided with a first guide surface. The first guide surface approaches the mounting plate along a first direction, so that the guide surface guides the pressing block to move closer to the placement surface.

[0016] Specifically, after the first mounting bracket drives the second mounting bracket to abut against the plate in the first direction, the first mounting bracket continues to move closer to the plate. Since the second mounting bracket is in contact with the plate, it does not move relative to the plate. That is, the first mounting bracket will drive the first guide surface of the guide block to approach the mounting plate in the first direction, so that the guide surface guides the lower pressure block to move closer to the placement surface, thereby completing the pressing of the plate, so that the operator does not need to adjust the lower pressure block.

[0017] In some embodiments, the side of the pressing block facing the first mounting bracket is provided with a second guide surface corresponding to the first guide surface.

[0018] In the above technical solution, a second guide surface corresponding to the first guide surface is provided on the side of the lower pressure block facing the first mounting bracket, so that the lower pressure block and the guide block are in surface contact, thereby reducing the wear when the guide block and the lower pressure block slide relative to each other and extending the service life of the sliding component.

[0019] In some embodiments, the pressure block is elastically connected to the mounting plate.

[0020] In the above technical solution, the pressure block is elastically connected to the mounting plate, so that when the guide block moves away from the pressure block, the pressure block can be elastically reset, thereby reducing the operator's operation.

[0021] In some embodiments, the sliding assembly further includes a second guide rod and a second spring. The second guide rod extends along the direction of gravity, with one end disposed on the side of the lower pressure block facing the mounting plate. A second guide hole is provided on the mounting plate, and the other end of the second guide rod passes through the second guide hole. The second spring is sleeved outside the second guide hole, with both ends of the second spring connected to the lower pressure block and the mounting plate, respectively. The lower pressure block moves toward the placement surface to stretch the first spring.

[0022] In the above technical solution, by setting a second guide rod and a second spring, on the one hand, the lower pressure block can be elastically connected to the mounting plate; on the other hand, the movement of the lower pressure block relative to the mounting plate in a direction that is at an angle to the direction of gravity can be restricted, so that the lower pressure block can press the plate more smoothly and restrict the movement of the plate in gravity more stably.

[0023] In some embodiments, the placement surface has a cutout portion for the waste material to fall off after being cut.

[0024] The above technical solution facilitates the operator's cleaning of the placement surface after cutting the plate. Attached Figure Description

[0030] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0031] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In the process of creating models of ancient buildings, in order to approximate the original structure of the building as closely as possible, a large number of non-standard panels need to be made. For example, model parts such as screens, doors, partitions, and ceiling panels all need to be cut from whole pieces of wood to form non-standard parts before carving. However, different non-standard parts have different lengths, widths, and thicknesses, and existing cutting devices are difficult to cut panels of various sizes in a fixed manner.

[0035] To solve the above technical problems, refer to Figures 1-4This application provides a sheet metal cutting machine 100, including a platform 10, a cutting mechanism 20, and a clamping mechanism 30. The platform 10 has a placement surface 121 for supporting sheet metal along the gravity direction Z; the cutting mechanism 20 is located above the placement surface 121 and is configured to move along a first direction X and a second direction Y to cut sheet metal, wherein the first direction X, the second direction Y, and the gravity direction Z are perpendicular to each other; the clamping mechanism 30 is configured to move along the first direction X, and there are two clamping mechanisms 30 spaced apart along the first direction X, with a first clamping gap between the two clamping mechanisms 30 for clamping sheet metal; wherein the clamping mechanism 30 includes a sliding component 31 and a pressing block 32, the first clamping gap is located between the sliding components 31 of the two clamping mechanisms 30, the pressing block 32 is adjustablely disposed within the sliding component 31 along the gravity direction Z, and there is a second clamping gap between the pressing block 32 and the placement surface 121 for clamping sheet metal.

[0036] In some embodiments, the platform 10 may include a mounting frame 11 and two placement beams 12 disposed within the mounting frame 11. The two placement beams 12 may extend along a first direction X and a second direction Y, respectively, and are connected at their midpoints. A clamping mechanism 30 is slidably disposed on the placement beam 12 extending along the first direction X. Exemplarily, the placement beam 12 has grooves on both sides in the second direction Y, and the clamping mechanism 30 has sliders adapted to the grooves. The sliders are slidably disposed within the grooves. The sides of the two placement beams 12 facing away from the ground are flush and together form a placement surface 121.

[0037] The cutting mechanism 20 may include a dual-axis platform 21 and a cutting blade 22. Understandably, the dual-axis platform 21 may be a platform composed of two linear modules, which extend along a first direction X and a second direction Y, respectively. The cutting blade 22 is mounted on the output mechanism of one of the linear modules, which in turn is mounted on the output mechanism of the other linear module to drive the cutting blade 22 to move along the first direction X and the second direction Y.

[0038] The cutting blade 22 can be a chainsaw cutting blade or a laser cutting blade 22.

[0039] Specifically, when processing the sheet material, the sheet material to be processed is placed on the placement surface 121, with the thickness direction of the sheet material parallel to the gravity direction Z. The distance between the two clamping mechanisms 30 in the first direction X is adjusted to restrict the movement of the sheet material to be processed. The movement of the sheet material to be processed in the gravity direction Z is restricted by the pressure block 32 and the placement surface 121, and the movement of the sheet material to be processed in the second direction Y is restricted by the friction between the pressure block 32 and the sheet material to be processed to fix the sheet material to be processed. At this time, the cutting mechanism 20 cuts the sheet material to be processed so that the dimensions of the sheet material to be processed in the second direction Y meet the length or width requirements of the non-standard sheet material to be processed.

[0040] The sheet material to be processed is then rotated so that the direction in which the sheet material meets the dimensions required for the non-standard sheet material to be processed is parallel to the first direction X. Two clamping mechanisms 30 are then used to restrict the movement of the sheet material in the first direction X. The movement of the sheet material in the direction of gravity Z is restricted by the pressure block 32 and the placement surface 121, and the movement of the sheet material in the second direction Y is restricted by the friction between the pressure block 32 and the sheet material to fix the sheet material. Subsequently, the sheet material is cut by the cutting mechanism 20 so that the dimensions of the sheet material in the second direction Y meet the width or length requirements of the non-standard sheet material to be processed. This achieves the fixing and processing of sheets of different sizes.

[0041] According to some embodiments of this application, the sheet metal cutting machine 100 further includes a first lead screw 40 and a second lead screw 42, the first lead screw 40 and the second lead screw 42 having opposite rotation directions, one end of the first lead screw 40 and one end of the second lead screw 42 being coaxially arranged and connected to each other; wherein, the sliding component 31 of one of the two clamping mechanisms 30 has a first threaded hole that is threadedly engaged with the first lead screw 40, and the sliding component 31 of the other of the two clamping mechanisms 30 has a second threaded hole that is threadedly engaged with the second lead screw 42.

[0042] For example, the first lead screw 40 and the second lead screw 42 can be driven by a handle.

[0043] In this technical solution, the first lead screw 40 and the second lead screw 42 rotate in opposite directions, and the sliding component 31 of one of the two clamping mechanisms 30 has a first threaded hole that is threadedly engaged with the first lead screw 40, and the sliding component 31 of the other of the two clamping mechanisms 30 has a first threaded hole that is threadedly engaged with the second lead screw 42. Thus, by rotating the first lead screw 40 and the second lead screw 42, the two sliding components 31 can be driven to move closer and further apart. The structure is simple and easy to implement.

[0044] According to some embodiments of this application, the sliding assembly 31 includes a first mounting bracket 311 and a second mounting bracket 312. The first mounting bracket 311 is slidably disposed on the stage 10 along a first direction X; the second mounting bracket 312 is disposed on the side of the first mounting bracket 311 facing the other sliding assembly 31 and is elastically connected to the first mounting bracket 311, and a first clamping gap is located between the second mounting brackets 312 of the two clamping mechanisms 30.

[0045] For example, the first mounting bracket 311 may be frame-shaped and may be fitted over the storage beam 12, with the slider disposed inside the first mounting bracket 311 in the second direction Y. The second mounting bracket 312 may be frame-shaped and may be fitted over the storage beam 12.

[0046] In this technical solution, the second mounting bracket 312 is disposed on the side of the first mounting bracket 311 facing the other sliding component 31 and is elastically connected to the first mounting bracket 311. The first clamping gap is located between the second mounting brackets 312 of the two clamping mechanisms 30. Therefore, when the second mounting bracket 312 abuts against the plate in the first direction X, the compressive deformation at the elastic connection between the second mounting bracket 312 and the first mounting component gradually increases the compressive force transmitted from the first mounting bracket 311 to the second mounting bracket 312, thereby gradually increasing the compressive force of the second mounting bracket 312 on the plate and reducing the risk of the second mounting bracket 312 damaging the plate during clamping.

[0047] According to some embodiments of this application, the sliding assembly 31 further includes a first guide rod 313 and a first spring 314. The first guide rod 313 extends along a first direction X, and one end of the first guide rod 313 is disposed on the side of the second mounting bracket 312 facing the first mounting bracket 311. The first mounting bracket 311 is provided with a first guide hole, and the other end of the first guide rod 313 passes through the first guide hole. The first spring 314 is sleeved outside the first guide hole, and both ends of the first spring 314 are respectively connected to the first mounting bracket 311 and the second mounting bracket 312. The second mounting bracket 312 moves toward the first mounting bracket 311 to compress the first spring 314.

[0048] For example, the first spring 314 may be a compression spring.

[0049] Understandably, the first guide rod 313 and the first spring 314 can be multiple ones spaced apart along the second direction Y.

[0050] In this technical solution, by setting a first guide rod 313 and a first spring 314, on the one hand, the second mounting bracket 312 can be elastically connected to the first mounting bracket 311; on the other hand, the movement of the second mounting bracket 312 relative to the first mounting bracket 311 in a direction that forms an angle with the first direction X can be restricted, thereby enabling the second mounting bracket 312 to abut against the plate more smoothly, so as to more stably restrict the movement of the plate in the first direction X.

[0051] According to some embodiments of this application, the second mounting bracket 312 includes a mounting body 3121 and a mounting plate 3122. A first guide rod 313 is disposed on the side of the mounting body 3121 facing the first mounting bracket 311; the mounting plate 3122 is disposed on the side of the mounting body 3121 away from the first mounting bracket 311, the thickness direction of the mounting plate 3122 is parallel to the gravity direction Z, and the lower pressure block 32 is connected to the mounting plate 3122 and is located between the mounting plate 3122 and the placement surface 121.

[0052] In this technical solution, the mounting plate 3122 is set to facilitate the setting of the pressure block 32, and the structure is simple and easy to implement.

[0053] According to some embodiments of this application, the sliding assembly 31 further includes a guide block 315. The guide block 315 is disposed on the side of the first mounting bracket 311 facing the second mounting bracket 312, and a first guide surface 3151 is disposed on the side of the guide block 315 facing the pressing block 32. The first guide surface 3151 approaches the mounting plate 3122 along the first direction X, so that the guide surface guides the pressing block 32 to move closer to the placement surface 121.

[0054] In some embodiments, when the first spring 314 is not compressed, there may be a gap between the first guide surface 3151 and the lower pressure block 32.

[0055] For example, when the first spring 314 is not compressed, the distance between the first guide surface 3151 and the side of the guide block 315 away from the placement beam 12 in the gravity direction Z can gradually increase in the direction away from the second mounting bracket 312.

[0056] Specifically, after the first mounting bracket 311 drives the second mounting bracket 312 to abut against the plate in the first direction X, the first mounting bracket 311 continues to move closer to the plate. Since the second mounting bracket 312 is in contact with the plate, it does not move relative to the plate. That is, the first mounting bracket 311 will drive the first guide surface 3151 of the guide block 315 to approach the mounting plate 3122 along the first direction X, so that the guide surface guides the lower pressure block 32 to move closer to the placement surface 121, thereby completing the pressing of the plate, so that the operator does not need to adjust the lower pressure block 32.

[0057] According to some embodiments of this application, the side of the pressing block 32 facing the first mounting bracket 311 is provided with a second guide surface 321 corresponding to the first guide surface 3151.

[0058] For example, when the first spring 314 is not compressed, the distance between the second guide surface 321 and the side of the lower pressure block 32 near the placement beam 12 in the gravity direction Z can gradually increase in the direction away from the first mounting bracket 311.

[0059] In this technical solution, the side of the lower pressure block 32 facing the first mounting bracket 311 is provided with a second guide surface 321 corresponding to the first guide surface 3151, so that the lower pressure block 32 and the guide block 315 are in surface contact, thereby reducing the wear when the guide block 315 and the lower pressure block 32 slide relative to each other and extending the service life of the sliding assembly 31.

[0060] According to some embodiments of this application, the pressure block 32 is elastically connected to the mounting plate 3122.

[0061] In this technical solution, the pressure block 32 is elastically connected to the mounting plate 3122, so that when the guide block 315 moves away from the pressure block 32, the pressure block 32 can be elastically reset, thereby reducing the operator's operation.

[0062] According to some embodiments of this application, the sliding assembly 31 further includes a second guide rod 316 and a second spring 317. The second guide rod 316 extends along the direction of gravity Z, and one end of the second guide rod 316 is disposed on the side of the lower pressure block 32 facing the mounting plate 3122. The mounting plate 3122 is provided with a second guide hole, and the other end of the second guide rod 316 passes through the second guide hole. The second spring 317 is sleeved outside the second guide hole, and both ends of the second spring 317 are respectively connected to the lower pressure block 32 and the mounting plate 3122. The lower pressure block 32 moves toward the placement surface 121 to stretch the first spring 314.

[0063] In this technical solution, by setting a second guide rod 316 and a second spring 317, on the one hand, the lower pressure block 32 can be elastically connected to the mounting plate 3122; on the other hand, the movement of the lower pressure block 32 relative to the mounting plate 3122 in a direction that makes an angle with the direction of gravity Z can be restricted, thereby enabling the lower pressure block 32 to press the plate more smoothly, so as to more stably restrict the movement of the plate under gravity.

[0064] According to some embodiments of this application, the placement surface 121 has a cutout portion 122 for the waste material to fall off after being cut.

[0065] In some embodiments, the gap between the storage beam 12 and the mounting frame 11 forms a cutout portion 122.

[0066] In this technical solution, it is convenient for the operator to clean the placement surface 121 after cutting the plate. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0067] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
