Description

Technical Field

[0001] The invention relates to a heavy-load supporting passive moving device and a moving method thereof, and belongs to the technical field of fiber composite material manufacturing equipment. Background Art

[0002] Fiber composite cylinders offer advantages such as high specific strength, high specific modulus, and designable structures. They meet the demands of modern weapon protection equipment for lightweight, large cross-sections, and long dimensions. They also enhance the mobility of transport vehicles, leading to their increasing application in weapon protection. Fiber composite cylinders are typically produced using a wet continuous filament winding process, which requires a core mold that meets the required inner diameter. After the fiber composite cylinder is formed and cured on the core mold, the fiber composite cylinder product must be separated from the core mold.

[0003] For fiber composite cylinders with diameters greater than 400mm and lengths greater than 5000mm, the metal core molds used to form them are large, heavy, require high surface precision, and are expensive. The core molds require two cranes to operate simultaneously during use, and are often rotated using a rotating device. However, during demolding, the fiber composite cylinders must rotate the core mold to coordinate with the demolding fixture, and rotating equipment cannot be used. Furthermore, during the demolding process, as the demolding pressure ejects the core mold, it is necessary to maintain axial horizontal movement in accordance with the ejection speed to prevent damage to the mold surface and the product molded therein. The manual operation and unstable movement of the crane cannot ensure stable and coordinated ejection of the core mold. Furthermore, due to the large size of the product, the demolding time is often long, which in turn requires the crane to be used for a long time, affecting the crane's use for other products. This requires a supporting device that can rotate the core mold in conjunction with the demolding fixture during demolding, coordinate stable movement with the ejection movement, and replace the crane's time constraints. Summary of the Invention

[0004] In order to solve the technical problems mentioned in the above background technology, the present invention proposes a heavy-load support passive moving device and a moving method thereof, which is suitable for supporting heavy core molds of various sizes, so that they do not rely on rotating equipment and double crane equipment for rotation and movement, avoiding long-term occupation of the crane, and meeting the requirements of circumferential coordinated rotation and axial stable coordinated movement of heavy core molds during operation and processing, thereby realizing stable and safe removal of the core mold during the demolding of the fiber composite material cylinder.

[0005] The present invention provides a method for moving a heavy-load support passive moving device, in which a plurality of support wheels are respectively mounted and fixed on respective transmission seats. By rotating a hand wheel to drive a lead screw to move, the transmission seat moves along a linear guide rail, thereby adjusting the distance between the support wheels to support heavy core molds or products of different sizes. A circumferential force is applied to the core mold, and the support wheels rotate under the action of the force to achieve circumferential coordinated rotation of the core mold, thereby meeting the rotation requirements during product operation and processing.

[0006] The mining wheel with bearing bush is placed on the light rail. During the demoulding process, the ejected core mold is placed on the supporting wheel. The demoulding pressure acts on the heavy-load supporting passive moving device through the core mold, pushing the wheelset to move along the light rail track to realize the axial movement of the core mold.

[0007] Preferably, the lead screw is fixedly connected to the linear guide rail base plate through a lead screw support seat and a lead screw fixing seat, and the lead screw is driven to move by a handwheel to realize transmission.

[0008] A heavy-load supported passive mobile device includes several mining wheels with bearings, a base plate, a linear guide base plate, a linear guide, two transmission seats, a transmission device, a drive device and a support wheel. The mining wheels with bearings are installed on both sides of the base plate. The linear guide base plate is vertically installed on the base plate. A linear guide is provided on the linear guide base plate. The two transmission seats are connected to the transmission device. The drive device drives the transmission device and then drives the transmission seat to move along the linear guide. A support wheel is installed on each transmission seat.

[0009] Preferably, the transmission device is a screw, and the transmission seat is installed on the screw.

[0010] Preferably, the driving device is a handwheel, and the handwheel is connected to the lead screw.

[0011] Preferably, the transmission seat includes a transmission seat base plate, a transmission center block, two linear guide sliding blocks and a linear guide mounting groove. The transmission center block is installed on the central axis below the transmission seat base plate, and linear guide sliding blocks are installed on both sides below the transmission seat base plate. A screw matching hole is provided on the transmission center block, and the screw passes through the screw matching hole of the transmission center block.

[0012] Preferably, lubricating oil is applied to each linear guide rail and the linear guide rail mounting groove, and the transmission seat base plate with the linear guide rail sliding block and the transmission center block installed is connected by pushing the linear guide rail and the base plate into the linear guide rail mounting groove.

[0013] Preferably, the mining wheel with bearing bush is threadedly connected to the base plate via a fixed connecting plate.

[0014] Preferably, the mining wheel with bearing bush is placed on a light rail.

[0015] Preferably, the bottom plate is reinforced by a bottom plate reinforcement plate.

[0016] The beneficial effects of the heavy-load support passive movement device and the movement method thereof of the present invention are:

[0017] (1) The heavy-duty support passive movement device and the movement method described in the present invention can realize the movement and rotation of the metal core mold for large fiber composite material cylinder molding in the operating environment. By rotating the hand wheel to drive the screw to move, the transmission seat moves along the linear guide rail to adjust the distance between the support wheels to support heavy core molds or products of different sizes. A circumferential force is applied to the core mold, and the support wheels rotate under the action of the force to achieve circumferential coordinated rotation of the core mold, meeting the rotation requirements during product operation and processing. The wheel with bearing bush is placed on the light rail. During the demoulding process, the core mold is ejected with the demoulding pressure and placed on the support wheel. The demoulding pressure acts on the heavy-load support passive moving device through the core mold, pushing the wheel set to cooperate with the core mold to eject at a speed that keeps the core mold moving horizontally along the axial direction of the light rail track. This effectively avoids damage to the mold surface and the product formed thereon during the demoulding process, solves the dependence on the crane and the machine time during the core mold ejection process in traditional operations, and avoids damage to the core mold and safety hazards caused by the mismatch between the unstable movement caused by manual operation of the crane and the stable movement of the core mold during ejection. Especially for larger core molds and products, this effectively solves the problems of crane occupancy time during demoulding and the safety of core mold movement during demoulding.

[0018] (2) The heavy-duty support passive moving device and its moving method described in the present invention not only effectively solve the problem of two cranes being required to operate simultaneously when moving the metal core mold for molding that is large in size, heavy in mass, requires high surface precision, and is expensive, but also solves the problem that the large core mold cannot be rotated with the help of rotating equipment during demoulding. In certain cases, it also eliminates the dependence on rotating equipment when rotating the large core mold. The heavy-duty support passive moving device and its moving method are suitable for supporting heavy core molds of various sizes, solving the problems of safety during demoulding of large products, rotating the core mold with the demoulding tooling, coordinating stable movement with the core mold ejection movement, and replacing the time occupied by the crane. It does not rely on rotating equipment and double crane equipment for rotation and movement, meets the requirements of safety, circumferential coordinated rotation, and axial stable coordinated movement of the heavy core mold during operation and processing, and realizes the stable and safe ejection of the core mold during the demoulding of the fiber composite material cylinder. While saving costs, space, crane time, and rotating equipment, it effectively reduces the damage to the core mold during multiple turnovers and increases the service life of the core mold.

[0044] The transmission device is a screw 12, and the transmission base 8 is mounted on the screw 12. The driving device is a handwheel 10, and the handwheel 10 is connected to the screw 12. There are two screws 12, which are arranged opposite each other, with the handwheel 10 mounted on the head and the tail facing each other.

[0045] The transmission base 8 includes a transmission base base plate 16, a transmission center block 17, two linear guide sliding blocks 19 and a linear guide mounting groove 20. The transmission center block 17 is installed on the central axis below the transmission base base plate 16, and the linear guide sliding blocks 19 are installed on both sides below the transmission base base plate 16. A screw matching hole 18 is provided on the transmission center block 17, and the screw 12 passes through the screw matching hole 18 of the transmission center block 17.

[0046] Apply lubricating oil to each linear guide rail 7 and the linear guide rail mounting groove 20, and connect the transmission seat base plate 16 with the linear guide rail sliding block 19 and the transmission center block 17 by pushing the linear guide rail mounting groove 20 into the linear guide rail 7 and the base plate 3.

[0047] The bearing-shrouded mining wheel 1 is threadedly connected to the base plate 3 through four fixed connecting plates 5. The bearing connection surface 25 matches the bearing of the wheelset and is tightened and fixed with hexagon socket bolts inserted into the mounting holes 28 on the base plate 3 and the threaded holes 26 on the fixed connecting plates 5. The base plate 3 is reinforced by the base plate reinforcement plate 4 to achieve a fixed combination of multiple bearing-shrouded mining wheel 1.

[0048] The linear guide base plate 6 is tightened and fixed by inserting the hexagon socket bolts into the two sets of connection holes 31 of the base plate 3 and the two sets of threaded holes 30 of the base plate 3, thereby achieving a fixed connection between the linear guide base plate 6 and the base plate 3. The four linear guide rails 7 are tightened and fixed by inserting the hexagon socket bolts into the linear guide fixed connection holes 42 and the threaded holes 21 on the linear guide base plate 6. The two screw support seats 9 are tightened and fixed by inserting the hexagon socket bolts into the connection holes 37 and the threaded holes 32 of the base plate 3. After the base plate 3, the linear guide base plate 6, the linear guide rails 7 and the screw support seat 9 are assembled and installed, the following is shown: Figure 8 shown.

[0049] The transmission center block 17 is connected to the transmission base plate 16 by inserting hexagon socket bolts into the mounting holes 33. The two linear guide slide blocks 19 are connected to the transmission base plate 16 by inserting hexagon socket bolts into the mounting holes 34. The thrust bearing 15 and the screw-fixing seat mating hole 44 of the screw fixing seat 11 are installed in the keyway end of the screw 12. The handwheel 10 is connected to the screw 12, and the fixing key 40 is inserted into the screw keyway 39 to secure the handwheel 10 and the screw 12.

[0050] Install the lead screw 12 into the lead screw mating hole 18 of the transmission center block 17. Apply lubricating oil to each linear guide rail 7 and the guide rail mounting slot 20. Connect the transmission base plate 16, with the linear guide slide block 19 and transmission center block 17 installed, by pushing the guide rail mounting slot 20 into the linear guide and base plate 3. Install the end of the lead screw 12 into the support hole 36 of the lead screw support base 9. Insert the hexagon socket head cap screw through the lead screw fixing hole 45 of the lead screw fixing base 11 and the threaded hole 24 of the linear guide base plate 3 and tighten to secure. Install the polyurethane support wheel 14 into the transmission base 8 through the threaded hole 38.

[0051] The moving method of the heavy-load support passive moving device is:

[0052] By rotating the handwheel 10, the lead screw 12 moves, causing the transmission base 8 to move along the linear guide rail, adjusting the distance between the polyurethane support wheels 14 to support heavy core molds or products of varying sizes. A circumferential force is applied to the core mold, causing the support wheels 14 to rotate in response to the force, achieving coordinated circumferential rotation of the core mold, meeting the rotation requirements during product operation and processing.

[0053] The mining wheel 1 with bearing bush is placed on the light rail 41. During the demoulding process, the ejected core mold is placed on the polyurethane support wheel 14. The demoulding pressure acts on the moving device through the core mold, pushing the wheel set to move along the light rail track to achieve axial movement of the core mold, effectively avoiding damage to the mold surface and the product molded thereon during the demoulding process, solving the dependence and machine time of the core mold ejection process during traditional operation, and avoiding the damage and safety hazards caused to the core mold by the mismatch between the unstable movement caused by the manual operation of the crane and the stable movement of the core mold during ejection. Especially for larger core molds and products, it effectively solves the problems of crane occupation time during demoulding and the safety of core mold movement during demoulding.

[0054] The heavy-duty support passive movement device and its movement method described in the present invention not only effectively solve the problem of large, heavy, high-precision, and expensive metal core molds for molding that require two cranes to operate simultaneously during use, but also solve the problem of large core molds being unable to rotate with the help of rotating equipment during demolding. In certain circumstances, it also eliminates the dependence on rotating equipment when rotating large core molds. The heavy-duty support passive movement device and its movement method are suitable for supporting heavy core molds of various sizes. They solve the problems of safety during demolding of large products, rotating the core mold with demolding tooling, coordinating stable movement with the core mold removal movement, and replacing the time occupied by cranes. They do not rely on rotating equipment or dual crane equipment for rotation and movement, meet the requirements of safe, circumferentially coordinated rotation, and axially stable coordinated movement of heavy core molds during operation and processing, and achieve stable and safe removal of the core mold during the demolding of fiber composite cylinders. While saving costs, space, crane time, and rotating equipment, they effectively reduce damage to the core mold during multiple turnovers and increase the service life of the core mold.

It should be understood that the above description is merely a specific embodiment of the present invention and is not intended to limit the present invention. It can also be a reasonable combination of the features described in the above embodiments.
