Description

Technical Field

[0001] The utility model belongs to the technical field of composite material manufacturing, and particularly relates to a preforming device for composite material truss products. Background Technique

[0002] The composite material forming process in composite material manufacturing is an important link. At present, there are problems such as unstable quality, high technical requirements for operators, or excessive manufacturing costs in the manufacturing of composite material truss products. Moreover, the existing forming processes are difficult to take into account aspects such as low operation level requirements, simple operation process, and low operation costs. This has led to problems such as long manufacturing periods, low material utilization rates, low production efficiency, and high personnel losses in the manufacturing process of some complex truss composite materials. Facing the above problems, complex composite material forming processes require more R & D investment and technological breakthroughs. The research and development of new forming technologies and equipment will help solve existing problems and promote the development of the composite material manufacturing industry.

[0003] In order to solve the above problems existing in the prior art, the utility model provides a preforming device for composite material truss products. Content of the Utility Model

[0004] The purpose of the utility model is to provide a preforming device for composite material truss products.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A preforming device for composite material truss products includes a device support. A heating workbench is arranged at the top of the device support. An airbag box is arranged above the heating workbench. The airbag box is fixedly connected to the heating workbench through four symmetrically arranged hydraulic rods. A gap is left between the airbag box and the heating workbench. The heating workbench is used to place the plates to be preformed and the corresponding molds. An inflatable airbag is attached inside the airbag box, and an airbag inflatable tube is attached to the inflatable airbag. The airbag inflatable tube extends out from the opening formed on the airbag box. The bottom surface of the heating workbench is fixedly connected with heating tubes, and the ends of the heating tubes are connected to external extension plugs. A hydraulic oil tank is installed on the device support, and four hydraulic oil pipes are connected to the hydraulic oil tank. The four hydraulic oil pipes are respectively connected to the four hydraulic rods.

[0006] Further, a motor is installed on the device support, and the motor is connected to the hydraulic oil tank.

[0007] Further, a control workboard is arranged on the device support, and the control workboard is electrically connected to the motor.

[0008] Further, four universal floor casters are arranged at the bottom of the device support.

[0009] Further, the airbag box is made of flexible material.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] (1) By providing an airbag box with an internally attached forming airbag, after the forming airbag is inflated, it can be applied to various different types of plates. By using the forming airbag to fit with the product to be preformed, the preforming is compacted tightly and the contact is comprehensive, enabling accurate forming. The soft characteristics of the forming airbag can prevent the preformed plate from being damaged during the processing;

[0012] (2) By providing a control working plate and an electro-hydraulic rod, the hydraulic rod can move up and down as required, driving the airbag box to lift. The design of the control working plate facilitates controlling the height of the airbag, so as to achieve different pressing degrees for different types of products. The up and down movement of the hydraulic rod is hydraulically controlled, which can avoid the phenomenon of crushing the product caused by the too fast descending speed of the airbag box;

[0013] (3) By providing a heating workbench, by connecting to an external power supply, the heating workbench heats up the mold and the plate. After the composite material product is heated and softened, it is more convenient to fit with the forming airbag for accurate preforming;

[0014] (4) By providing a device support, the device support can stably support and place the device. Four universal floor casters are attached to the bottom of the device support. When using the present utility model, the device support can be pushed according to the situation to drive the universal floor casters, which is convenient for moving and using.
