Description

Technical Field

[0001] The present application relates to the field of wet wound product processing, and in particular to a wet wound product curing machine tool. Background Art

[0002] The wet winding process is a method for preparing composite materials. The main process is to impregnate continuous fiber filaments or fiber cloth in resin, then directly wind them on the mold under the guidance of the wire nozzle, and then place them. As the resin hardens, the fibers are bonded together to achieve the purpose of curing and molding. Compared with dry winding, the cost of wet winding can be reduced by 40%, and due to the effect of winding tension, the airtightness is good. However, the glue content and distribution of the wet winding process affect the final quality of the product.

[0003] In the prior art, after the wet winding products are formed, they are generally placed vertically in a room temperature environment or in an oven for curing. At this time, the resin above the product will flow to the bottom of the product due to gravity. This curing method will cause excessive glue flow in the product, which can easily cause defects such as uneven glue content and local color difference in the product. Utility Model Content

[0004] The purpose of the present application is to solve the problem in the prior art that the original curing method will cause excessive glue flow in the product, which is very likely to cause defects such as uneven glue content in the product and local color difference.

[0005] An embodiment of the present application provides a wet-wound product curing machine, which allows the wet-wound product to continuously rotate during the curing process, so that the glue is distributed more evenly on the product, avoiding problems such as glue flow and local color difference.

[0006] The embodiment of the present application provides a wet wound product curing machine, wherein the support frame is provided with a clamping device; the clamping device comprises a spindle device and an ejector pin, and the spindle device and the ejector pin are respectively located on both sides of the support frame, so as to clamp the wet wound product;

[0007] The spindle device has a rotating shaft, and the spindle device is driven by a motor to rotate along the rotating shaft;

[0008] The ejector set includes an ejector sleeve and an ejector pin, wherein the ejector pin is opposite to the rotating shaft and is used to support the wet-wound product to keep it horizontal, and the ejector pin is rotatably connected to the ejector sleeve through a thread, and the purpose of clamping the core mold and fixing the wet-wound product is achieved by rotating the ejector pin;

[0009] A plurality of the clamping devices are arranged on the support frame, and adjacent clamping devices are connected by a flat double sprocket and a chain arranged side by side, so that the clamping devices can rotate in the same direction at the same time.

[0010] By using the above technical solution, the wet-wound product can be suspended on the support frame through the clamping device, and the wet-wound product can be driven by a motor to rotate continuously, and solidified during the rotation process, so that the overall distribution of the glue is more uniform, glue flow is less likely to occur, and the quality of the wet-wound product is better; on the other hand, a plurality of adjacent clamping devices are installed on the support frame, and a plurality of wet-wound products can be placed at the same time. At the same time, the flat double sprockets arranged on the adjacent clamping devices are connected by a chain drive, so that one motor can be used to drive all the wet-wound products to rotate at the same time, which makes the efficiency higher, saves energy, and can ensure that all the wet-wound products can rotate in the same direction; the ejector pin can be extended by rotation to support the wet-wound product, which is easier to operate and plays a supporting role, so that the wet-wound product remains horizontal.

[0011] In one embodiment, at least two guide rails are further provided on the support frame, and the guide rails are arranged in parallel along the connecting direction of the spindle device and the ejector pin. A guide rail slider is slidably provided on the guide rail, and the ejector pin is fixedly provided on the guide rail slider.

[0012] By adopting this solution, the distance between the ejector pin and the spindle device can be adjusted by means of the slider and the slide rail. When clamping, the slider is adjusted to bring the ejector pin closer to the wet-wound product, so that the equipment can meet the rotational curing requirements of products of different lengths.

[0013] In one embodiment, the motor is fixed on a supporting frame, and an output end of the motor is connected to a spindle device through a chain to drive the spindle device to rotate.

[0014] A toothed chain is used to drive the main shaft device to rotate, which has a simple structure and lower cost.

[0015] In one embodiment, the ejector sleeve is fixedly connected to the guide rail slider.

[0016] In one embodiment, a collecting space is provided below the connecting line between the spindle device and the ejector set, in which a collecting bucket can be placed to collect dripping resin, and baffles are installed on the spindle device and the motor.

[0017] This technical solution can prevent the glue from dripping onto the ground, making it difficult to clean up, or dripping onto the spindle device and affecting the operation of the device.

[0018] In one embodiment, the spindle device includes a three-jaw chuck for clamping the core mold, a bearing seat is fixedly installed on the support frame, a bearing is arranged in the bearing seat, and one end of the three-jaw chuck is rotatably connected to the bearing through a transmission shaft;

[0019] A support seat is arranged between the three-jaw chuck and the bearing seat. The support seat is fixed on the support frame and is used to support the transmission shaft. The transmission shaft is fixedly connected with flat double sprockets arranged side by side. The flat double sprockets on adjacent transmission shafts are connected by chain transmission.

[0020] By adopting this technical solution, a three-jaw chuck can be used to clamp different types of wet-wound products, which is more applicable. In order to make the structure more stable, a support seat is added.

[0021] In one embodiment, two support seats are used on each transmission shaft, and the support seats include a bearing seat and a bearing. The bearing seat is fixed on the support frame, and the bearing is arranged in the bearing seat. The transmission shaft passes through the bearing, and the bearing provides support for the transmission shaft without affecting the rotation of the transmission shaft.

[0022] This support method can constrain the movement of the main shaft device, and the two support seats are set to prevent the structure from shaking when rotating, thereby improving stability and increasing bearing capacity.

[0023] In one embodiment, a lampshade cover plate may be installed above the support frame, so that all wet-wound products can be covered in the cover plate.

[0024] Adopting this solution can make the product less likely to be contaminated by the outside world.

[0025] Other features and corresponding beneficial effects of the present invention are described in the latter part of the specification, and it should be understood that at least part of the beneficial effects become obvious from the description in the specification of the present invention.
