Description

Technical Field

[0001] The utility model relates to the technical field of pre-oxidized silk felt processing, in particular to a positioning and cutting device for pre-oxidized silk felt processing. Background Art

[0002] The origin of preoxidized silk felt is closely related to the development of carbon fiber and the demand for high-performance fiber materials. Carbon fiber has excellent properties such as high strength, high modulus, and high temperature resistance. It has important applications in aerospace, military and other fields. Preoxidized silk is the primary raw material of carbon fiber. In the process of exploring the preparation of carbon fiber, researchers found that polyacrylonitrile fiber can form a fiber with special properties after preoxidation treatment, which laid the foundation for the emergence of preoxidized silk felt. In short, preoxidized silk felt is a new type of high-performance material produced by the preoxidation treatment of fibers and the application of felt product preparation technology on the basis of the continuous development of carbon fiber technology. It has broad application prospects in the fields of heat insulation, flame retardancy, and thermal insulation.

[0003] In the existing technology, in aircraft manufacturing, pre-oxidized fiber felt can be used to manufacture thermal insulation components. The positioning and cutting device can accurately cut the pre-oxidized fiber felt into specific shapes and sizes, which are used for the thermal insulation layer of the aircraft engine compartment and the thermal insulation components inside the fuselage. During use, translation and rotational displacement may occur during the cutting process. If positioning is not performed, the accuracy of cutting will be affected. In addition, during the cutting process, the width of the pre-oxidized fiber felt is not convenient to measure, which makes it difficult to cut pre-oxidized fiber felt of different widths.

[0004] Therefore, a positioning and cutting device for processing pre-oxidized fiber felt is proposed. Utility Model Content

[0031] On the basis of Example 1, a preferred embodiment of a positioning and cutting device for processing pre-oxidized silk felt provided by the present invention is as follows: Figure 1-5 As shown, the measuring and cutting assembly 6 specifically includes: a concave plate 611, fixedly mounted on the top of the side plate 3; a support rod 612, fixedly mounted at equal intervals on the top of the concave plate 611; and a slide rail 614, fixedly mounted at equal intervals on the top of the concave plate 611.

[0032] A hole is provided at the top of the concave plate 611, and a scale rod 613 is fixedly connected to the other end of the support rod 612.

The inner wall of the marking sleeve 617 is movably sleeved on the outer wall of the scale rod 613.

[0033] A connecting plate 618 is fixedly installed between the concave sliders 615, and the bottom of the connecting plate 618 is fixedly installed on the T-shaped plate 619. The bottom of the T-shaped plate 619 movably passes through the inside of the hole and extends to the top of the inner wall of the concave plate 611. An electric telescopic rod 6111 is fixedly installed on the bottom of the T-shaped plate 619. The telescopic end of the electric telescopic rod 6111 is fixedly connected to a hollow fixed frame 6112. A motor 6113 is fixedly installed on one side of the hollow fixed frame 6112. The output end of the motor 6113 is fixedly connected to a rotating shaft. The other end of the rotating shaft movably passes through one side of the hollow fixed frame 6112 and extends to the inside of the hollow fixed frame 6112. The other end of the rotating shaft is fixedly installed with a cutting knife 6114.

[0034] In this example, precise left and right cutting is performed by setting up a measuring and cutting component 6. The electric telescopic rod 6111 pushes the hollow fixed frame 6112 down, and the motor 6113 drives the cutting knife 6114 to rotate and cut. When materials of different widths need to be cut, the connecting plate 618 is pushed to drive the concave slider 615 to move on the slide rail 614. The connecting plate 618 drives the hollow fixed frame 6112 to move in conjunction with the T-shaped plate 619 and the electric telescopic rod 6111.

The marking sleeve 617 slides on the ruler rod 613 to confirm the moving position, thereby improving the accuracy of the moving distance, thereby achieving the purpose of measuring and cutting.

[0035] Working principle: First, the positioning component 5 is set to position the material. The material is transported from the conveyor belt 4 and is limited when passing the limiting pulley 5113. The spring 5115 can apply pressure to the nail-shaped rod 5111, wherein the other end of the spring 5115 is fixed on the top of the inner wall of the top plate 5114. The nail-shaped rod 5111 applies pressure to the limiting pulley 5113 through the clamping block 5112. At the same time, the elasticity of the spring 5115 can provide buffering protection for the pre-oxidized silk felt. It is necessary to move the limiting pulley 5113 left and right. When the I-shaped slider 519 moves, it can drive the nail-shaped rod 5111, the clamping block 5112, and the limiting pulley 5113 to move, and drive the nail-shaped rod 5111, the spring 5115, and the top plate 5114 to move in conjunction. The moving position can be observed through the scale 518 to meet the positioning of materials of different widths. When the limiting pulley 5113 needs to be adjusted forward and backward, the operator rotates the regulating valve 513 to drive the screw 512 to rotate, wherein the screw 512 rotates and connects in the connecting block 511, and the screw 512 rotates to drive the screw 512 to rotate. The movable screw block 514 and the cross slider 516 move, and the cross slider 516 drives the L-shaped hollow rod 517 to move forward and backward. The cross slider 516 slides and limits in the cross slide 515 to meet the positioning of different positions in the front, back, left and right. Then, by setting the measuring and cutting component 6, accurate cutting is performed left and right. When cutting is required, the electric telescopic rod 6111 pushes the hollow fixed frame 6112 down, and the motor 6113 drives the cutting knife 6114 to rotate and cut. When materials of different widths need to be cut, the operator pushes the connecting plate 618 with The movable concave slider 615 moves on the slide rail 614, and the connecting plate 618 drives the hollow fixed frame 6112 to move in conjunction with it through the T-shaped plate 619 and the electric telescopic rod 6111. The movement of the concave slider 615 drives the L-shaped connecting rod 616 and the marking sleeve 617 to move in conjunction. The marking sleeve 617 slides on the ruler rod 613 to confirm the moving position. An observation hole is provided on the surface of the marking sleeve 617, which can accurately observe the moving distance and improve the accuracy of the moving distance, thereby achieving the purpose of positioning and measuring cutting.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
