Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting equipment, specifically a composite cutting device. Background Technology

[0002] In building structures such as roofs and wall sidewalls, adjacent sandwich panels (such as rock wool composite panels and polyurethane composite panels) typically require an overlapping connection. This means that the inner metal layer and the middle core board of one panel need to be removed from its edge, leaving only the outer metal layer. This section of the outer metal layer overlaps and is fixed to the outer wall of the adjacent panel. The processing of this overlapping structure requires two simultaneous operations: cutting the panel to a fixed length and partially removing the edges.

[0003] Existing technologies already include cutting equipment that combines band saws and circular saws. For example, Chinese utility model patent CN218138483U discloses a band saw machine for a double rock wool fireproof polyurethane composite board production line. This equipment includes a base, a support base, and a band saw blade. An upper circular saw driven by a first motor and a first lead screw is installed on top of the support base, and a lower circular saw driven by a second motor and a second lead screw is installed on top of the base. The upper and lower circular saws are responsible for cutting the cross-sections of calcium silicate boards and color steel plates in the board material, while the remaining portion is cut by the band saw blade, thereby extending the band saw blade's life and ensuring cutting quality. This equipment combines the band saw blade with the upper and lower circular saws into one unit, mainly used for cutting rigid composite boards such as double rock wool fireproof polyurethane composite boards. However, the above-mentioned existing technologies still have the following shortcomings: First, this equipment is mainly used for one-time through-cutting of composite panels. Its purpose is to completely cut the panel, rather than specifically processing the overlapping parts. For operation scenarios that require forming an overlapping part on one side (i.e., only removing the inner metal plate and the middle core plate, leaving the outer metal plate), this equipment is not directly applicable.

[0004] Secondly, the upper and lower circular saws of the equipment cut simultaneously from the upper and lower sides of the board, which is suitable for layered cutting of the board, but cannot achieve partial removal of one side of the board end, making it difficult to meet the special requirement of "removing only the inner metal plate and core plate and retaining the outer metal plate" in the processing of overlapping parts.

[0005] Third, after the equipment completes the cutting, if the overlapping parts need to be processed, the plate still needs to be transferred to other equipment for secondary clamping and partial cutting, which results in complicated procedures, time-consuming transfer, and low processing efficiency.

[0006] Fourth, existing technologies generally overlook the issue of the bonding time of sandwich composite panels. Sandwich composite panels are bonded and fixed by spraying adhesive. For a short period after bonding, the bond strength of each layer is still at a low level. At this time, local cutting of the overlapping area is relatively easy to peel off and remove. However, if the time is delayed due to equipment transportation and repeated clamping, the adhesive will further harden, making it difficult to remove the excess material cleanly. It may even damage the remaining outer metal plate, leading to failure of the overlapping area.

[0007] Therefore, it is necessary to develop a high-efficiency cutting device specifically for processing the overlapping parts of sandwich panels. This device should be improved upon existing composite cutting equipment to enable the simultaneous completion of two processes on a single machine: fixed-length cutting and partial removal of the overlapping parts. It should also allow for rapid switching between cutting and overlapping operations and utilize the time window after gluing for immediate processing, thus solving the problems existing in the prior art. Utility Model Content

[0008] The purpose of this utility model is to provide a composite cutting device in order to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a composite cutting device, including a base, the base being a box-shaped structure with an upper opening, a band saw being disposed above one side of the upper opening end of the base, and a moving mechanism being disposed between the base and the band saw for mounting the band saw in the length direction of the base and driving the band saw to move along the length direction of the base. Two brackets are installed on both sides of the base. A support plate is fixedly connected between the two brackets on the same side. A gap is left between the two support plates for the band saw blade to cut. The band saw is equipped with a cutting disc assembly at its upper end. The cutting disc assembly includes a mounting plate. Two symmetrically distributed second slide rails are mounted on one end face of the mounting plate. Two sets of linear modules are slidably mounted between the two second slide rails. The two sets of linear modules are symmetrically distributed. The drive end of each linear module is connected to a mounting frame. The lower end of the mounting frame is equipped with a cutting disc. The cutting disc is located above the support plate. The upper end of the mounting frame is equipped with a cutting motor that drives the cutting disc to rotate.

[0010] As a further embodiment of this utility model: the moving mechanism includes a first slide rail fixedly connected to both ends of the opening on the base, a slide block slidably connected to the first slide rail in the length direction, and a rack fixedly provided on the top of the first slide rail. A drive motor is installed inside the lower end of the band saw, and a gear is connected to the output end of the drive motor. The gear meshes with the rack.

[0011] As a further solution of the utility model: the driving motor is a double-shaft motor.

[0012] As a further solution of the utility model: a pressing component is further installed between two brackets on the same side, and is used to cooperate with the pallet to press and clamp the plate placed on the pallet.

[0013] As a further solution of the utility model: the pressing component includes a lifting chute opened on the inner side wall of the bracket. The opening sides of the lifting chutes on two brackets on the same side are arranged oppositely. A pressing frame is slidably connected between the two lifting chutes. The pressing frame is in a "C" shape structure. A driving member is installed at the lower end of the pressing frame, and the output end of the driving member is connected to the lower end of the pressing frame.

[0014] As a further solution of the utility model: the driving member is a hydraulic cylinder or a pneumatic cylinder or an electric telescopic rod.

[0015] As a further solution of the utility model: the cutting disc assembly further includes a screw rod for manually driving the linear module to move along the length direction of the second slide rail. The screw rod is threadedly connected with the linear module, and two ends of the screw rod are respectively fixed on the mounting plate through mounting seats. The screw rod is rotatably connected with the mounting seat through bearings.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: First, it realizes one-stop processing of the overlapping part and greatly improves the production efficiency. By combining a band saw machine and a double cutting disc assembly in the same device and adopting an alternating reciprocating operation mode of cutting operation and overlapping processing operation, the utility model enables a neat cut surface to be processed on one side of a plate and an overlapping part to be processed on the other side. All processes are continuously completed on one device without transferring between different devices and repeating clamping and positioning, significantly shortening the auxiliary time and improving the continuous operation level of the overlapping part processing.

[0017] Secondly, this invention reduces the processing difficulty of overlapping parts and improves the yield rate by utilizing the bonding time window. This invention can be installed behind the adhesive spraying and heat sealing mechanism and connected to its discharge end, allowing sandwich panels that have just undergone adhesive spraying and heat sealing to immediately enter the device for overlapping part processing. At this time, the adhesive has not yet fully cured, and the bonding strength between the layers is at a low level. The inner metal plate and the middle core plate cut off by the cutting disc are easier to peel off and remove, without causing damage to the remaining outer metal plate. Unlike existing split-type equipment where adhesive is difficult to peel off after complete curing due to transport delays, this invention fully utilizes the curing time window after bonding, effectively reducing processing difficulty and avoiding problems such as deformation, tearing, or even scrapping of the overlapping parts of the outer metal plate due to forced peeling.

[0018] Third, it ensures the processing accuracy of the overlapping parts and improves the splicing quality. This utility model integrates fixed-length cutting and partial cutting of the overlapping parts into the same equipment. The entire cutting operation can be completed after the board is clamped once, eliminating the positioning reference deviation caused by multiple clamping in the separate processing. At the same time, through the screw-driven dual cutting disc adjustment mechanism, the distance between the two cutting discs can be precisely adjusted according to the overlapping width requirements, ensuring that the cutting position of the overlapping part is consistent with the theoretical design position, thereby ensuring the reliability and sealing of the overlapping connection between adjacent boards.

[0019] Fourth, it is versatile and highly adaptable. This utility model can be used in conjunction with a band saw and a double cutting disc assembly to specifically process the overlapping parts of sandwich panels; it can also be used alone with the band saw for conventional fixed-length cutting operations when the overlapping parts do not need to be processed. This multi-purpose design meets the needs of different production scenarios and reduces equipment investment costs.

[0020] Fifth, it operates smoothly and produces high-quality cuts. This invention employs a dual-axis motor-driven rack and pinion moving mechanism, coupled with a first guide rail, to ensure uniform force on both sides and smooth, unbiased operation when the band saw and cutting disc assembly move as a whole. Simultaneously, the clamping assembly and the support plate together form a stable clamp, effectively preventing displacement or vibration of the sheet material during cutting, thus guaranteeing the quality of the cut surface from the band saw and the partial removal by the cutting disc.

[0021] In summary, this utility model effectively solves the problems in the prior art such as the need for separate operations in processing overlapping parts, time-consuming transportation, processing difficulties caused by the timeliness of gluing, and the impact of repeated positioning on accuracy. It is a high-efficiency, precise, and reliable composite cutting equipment specifically designed for processing overlapping parts of sandwich panels. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 In this embodiment of the invention, a composite cutting device includes a base 1, which is a box-shaped structure with an open top. A band saw 3 is mounted above one side of the open end of the base 1. A moving mechanism 2 is provided between the base 1 and the band saw 3 to mount the band saw 3 along the length of the base 1 and drive the band saw 3 to move along the length of the base 1. Two supports 4 are mounted on each of the two side walls of the base 1. A support plate 5 is fixedly connected between the two supports 4 on the same side, and a gap is left between the two support plates 5 for the band saw blade to cut.

[0026] A cutting disc assembly 7 is mounted on the upper end of the band saw 3. The cutting disc assembly 7 includes a mounting plate 701. Two symmetrically distributed second slide rails 702 are mounted on one end face of the mounting plate 701. Two sets of linear modules 705 are slidably mounted between the two second slide rails 702. The two sets of linear modules 705 are symmetrically distributed. The drive end of the linear module 705 is connected to a mounting frame 706. A cutting disc 707 is mounted on the lower end of the mounting frame 706. The cutting disc 707 is located above the support plate 5. A cutting motor 708 that drives the cutting disc 707 to rotate is mounted on the upper end of the mounting frame 706. By combining the band saw 3 and the double cutting disc assembly 7 into the same device, the band saw 3 can be used alone to cut the plate in a straight line, or the band saw 3 can be used in conjunction with the two sets of cutting discs 707 to process the overlapping part of one end of the plate (i.e., simultaneously complete fixed-length cutting and partial edge removal). It has multiple functions and high processing efficiency.

[0027] It should be noted that the band saw 3 in this solution is an existing band saw, which mainly consists of a protective shell, a drive saw wheel, a driven saw wheel, a tensioning assembly, and a motor. Its specific principles are all existing technologies, and will not be elaborated on here.

[0028] Please refer to this carefully. Figures 1-5 The moving mechanism 2 includes a first slide rail 201 fixedly connected to both ends of the opening on the base 1. A slide block 202 is slidably connected to the first slide rail 201 along its length, and a rack 203 is fixedly installed on the top of the first slide rail 201. A drive motor 204 is installed inside the lower end of the band saw 3. A gear 205 is connected to the output end of the drive motor 204. The gear 205 meshes with the rack 203. The drive motor 204 is a dual-axis motor. The drive motor 204 drives the gear 205 and the rack 203 to mesh and transmit power, thereby driving the band saw 3 to move along the length of the first slide rail 201. The drive motor 204 is an existing servo motor. With the meshing transmission of the gear 205 and the rack 203, the cutting stroke of the band saw 3 can be precisely controlled. The use of a dual-axis motor can ensure that the force on both sides is uniform, the movement is smooth and without deviation, and the cutting position can be automatically and accurately adjusted.

[0029] Please refer to this carefully. Figures 1-5, a pressing component 6 is also installed between two brackets 4 on the same side, which is used to cooperate with the pallet 5 to press and clamp the plate placed on the pallet 5. The pressing component 6 includes a lifting chute 601 opened on the inner side wall of the bracket 4. The opening sides of the lifting chutes 601 on the two brackets 4 on the same side are arranged opposite to each other. A pressing frame 602 is slidably connected between the two lifting chutes 601. The pressing frame 602 has a "C" - shaped structure. A driving part 603 is installed at the lower end of the pressing frame 602. The output end of the driving part 603 is connected to the lower end of the pressing frame 602. The driving part 603 is a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod. The driving part 603 can accurately control the position height of the pressing frame 602. The driving part 603 drives the pressing frame 602 to vertically lift along the lifting chute 601. Since the pressing frame 602 has a "C" - shaped structure, the upper cross beam of the pressing frame is used to press the plate from above, jointly forming a stable clamping with the pallet 5, effectively preventing the plate from shifting or vibrating during the cutting process, and ensuring the cutting accuracy and operation safety.

[0030] Please refer specifically to Figures 1-5 , the cutting disc assembly 7 further includes a lead screw 703 for manually driving the linear module 705 to move along the length direction of the second slide rail 702. The lead screw 703 is threadedly connected to the linear module 705, and the two ends of the lead screw 703 are respectively fixed on the mounting plate 701 through the mounting seats 704. The lead screw 703 is rotatably connected to the mounting seat 704 through a bearing. By manually rotating the lead screw, the linear module can be precisely fine - adjusted along the second slide rail, so as to adjust the relative position of the two cutting discs; this structure is convenient for quickly adjusting according to different plate sizes or lap width requirements, with simple operation and reliable positioning.

[0031] This equipment is specifically used for processing the lap joints of sandwich - type plates (such as rock wool composite plates, polyurethane composite plates, etc., used for roofs or side walls). During processing, a lap joint needs to be processed on one side of a plate (that is, the inner metal plate and the middle core plate are removed, and only the outer metal plate is retained), and the other side of the plate is a neat cut surface for cooperating with the lap joint of the adjacent plate. To achieve the above - mentioned purpose, this equipment adopts an operation mode of alternately reciprocating cutting operation and lap joint processing operation.

[0032] Specifically, the first operation is a cutting operation. First, the board to be processed is placed on two pallets 5. The drive unit 603 is started to press down the pressure frame 602 to fix the board. At this time, only the band saw 3 is started, and the cutting motor 708 in the cutting disc assembly 7 is not started. Then, the drive motor 204 is controlled to drive the gear 205 to mesh with the rack 203, so that the band saw 3 moves along the cutting direction and cuts the board in a straight line. After this operation is completed, one end of the board produced has a neat cut surface. The second operation is the overlapping processing operation. The remaining board material after the previous cut is pushed forward a predetermined distance and fixed again by the clamping component 6. At this time, the two sets of cutting motors 708 in the band saw 3 and the cutting disc assembly 7 are started at the same time. According to the overlap width requirements, the distance between the two cutting discs 707 is pre-adjusted by turning the screw 703. Then, the drive motor 204 is controlled to drive the band saw 3 and the cutting disc assembly 7 to move along the cutting direction. During this movement, the band saw 3 completes the transverse cut from the predetermined position of the board material. At the same time, the two sets of cutting discs 707 respectively perform partial cutting from the top of the board material to remove the inner metal plate and the middle core plate at this end, leaving only the outer metal plate, thereby forming an overlap at this end.

[0033] The cutting and overlapping operations are performed alternately in the above manner. The first operation uses only a band saw to produce a clean cut surface. The second operation uses both a band saw and two cutting discs to produce the overlapping section. The third operation again uses only a band saw to produce a clean cut surface. The fourth operation again uses both a band saw and two cutting discs to produce the overlapping section, and so on in a cyclical manner. Through this alternating operation method, each finished sheet produced by this equipment meets the requirement of having a clean cut surface on one side and an overlapping section on the other. The clean cut surface is used to fit against the outer wall of the adjacent sheet, while the overlapping section is used to cover and fix the outer wall of the adjacent sheet, thus achieving a reliable overlapping connection between adjacent sheets.

[0034] It should be noted that this solution is for processing the overlapping parts of sandwich composite panels (such as rock wool composite panels, polyurethane composite panels, and other multi-layer structural panels composed of thin metal sheets and core boards). During the actual cutting process, the cutting disc assembly 7 does not cut both ends of the panel completely, but only cuts the inner metal sheet and the middle core board at one end of the composite panel, retaining the outer metal sheet to form an overlapping section for subsequent overlap of adjacent panels. If only simple fixed-length cutting is required without processing the overlapping section, the band saw 3 can be used alone without starting the cutting disc assembly 7; in this case, the equipment can still complete the conventional cutting operation.

[0035] In actual production layout, this device can be installed behind the adhesive spraying and heat sealing mechanism and connected to the discharge end of that mechanism. After the sandwich composite panel completes the adhesive spraying and heat sealing of each layer in the adhesive spraying and heat sealing mechanism, it is immediately fed into this device for processing the overlapping parts. Since the adhesive between the layers has not fully cured when the composite panel is first glued, and the bonding strength is still at a low level, cutting the overlapping parts immediately and removing the cut inner metal plate and the middle core board makes the cut parts easier to peel off and remove without causing damage to the remaining outer metal plate. If the overlapping parts are processed after the composite panel has been glued and left for a long time (when the adhesive has fully cured and the layers are firmly bonded), even if the cutting is completed, the excess material is difficult to remove cleanly. Forced peeling can easily cause deformation or tearing of the remaining outer metal plate, or even render the entire overlapping part unusable. Therefore, by directly connecting this device to the glue spraying and heat sealing mechanism, and taking advantage of the time window when the composite board is not fully bonded after the heat sealing process to immediately process the overlapping part, the processing difficulty can be significantly reduced and the yield rate can be improved. This is one of the important advantages of this device compared with the existing split-type cutting equipment.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
