Description

Technical Field

[0001] This utility model patent relates to the field of mechanical assembly technology, and specifically, to a carbon fiber Z-shaped wall panel forming tooling. Background Art

[0002] Carbon fiber reinforced composite materials have the advantages of high specific modulus and specific strength, corrosion resistance, high temperature resistance, fatigue resistance, good damping and shock absorption, strong designability and good dimensional stability. Carbon fiber reinforced composite materials are widely used in aviation, aerospace and other fields. The application of composite materials in the field of civil aviation is gradually increasing. Because the reinforced structure has good torsional and bending rigidity, it has been widely used in mechanism design.

[0003] At present, after the plate is formed, the mold will be tightly attached to the product due to pressure. Conventional methods cannot be used to separate the product from the mold intact. If the operation is not careful, the product will be damaged or stuck in the mold and cannot be separated. This case provides a forming mold that can simply and quickly separate the product from the tooling. Utility Model Content

[0004] The utility model aims to provide a carbon fiber Z-shaped wall panel forming tooling, which aims to solve the problem. The utility model is implemented as follows: it includes a bottom plate for installing a fixing frame and carrying a carbon fiber plate to extrude and form the carbon fiber plate;

[0005] Also included are positioning components, mounting brackets, and carbon fiber plates;

[0006] The fixing frame is fixedly mounted on the surface of the bottom plate by bolts, and a carbon fiber plate is fixedly mounted on the surface of the fixing frame by a positioning assembly;

[0007] The positioning assembly includes a positioning pin and a pressing plate, the pressing plate is in an "L" shape, and the carbon fiber plate is placed under the pressing plate and is pressurized by a vacuum bag;

[0008] The surface of the fixing frame is provided with a step groove, the surface of the step groove is clamped with a top plate, the other side of the top plate is fixedly connected with a sliding shaft, the surface of the fixing frame is provided with a through hole, the sliding shaft is slidably connected in the through hole by a spring, a top shaft is slidably connected in the fixing frame, the surface of the top shaft is provided with an oblique angle, and the bottom surface of the sliding shaft is provided with an arc angle relative to the oblique angle of the top shaft surface. The carbon fiber plate to be formed is placed on the surface of the fixing block, and then the carbon fiber plate is positioned by the positioning component, and then the device is placed in a vacuum bag as a whole for vacuum bag press molding. After the carbon fiber plate is processed and formed, the top shaft is pushed in a direction close to the sliding shaft, so that the oblique angle of the top shaft surface squeezes the arc surface of the sliding shaft surface, so that the sliding shaft slides upward, and at the same time, the top plate is driven to move, so that the top plate lifts up and separates the carbon fiber plate on the surface of the fixing frame. After loosening, the spring drives the top plate to reset. Through the cooperation of the top plate, the fixing block and the pressing plate, the situation that the mold and the product are tightly attached together due to pressure can be effectively avoided, so that the finished product and the mold can be separated intact, thereby improving the yield rate, and having the advantages of convenient disassembly and assembly, safety and reliability.

[0009] Furthermore, the top plate is in an inverted "U" shape and has elasticity, a step groove is provided on the surface of the fixing frame, the top plate is sleeved on the surface of the step groove, and the surfaces of the two short arm ends of the top plate are provided with bevels, and the long arm end of the top plate is an arc shape that is recessed toward the fixing frame, the sliding shaft is provided with two groups, and each group has two, and they are symmetrically distributed with respect to the longitudinal and transverse midlines of the top plate, a cavity is provided in the fixing frame, a push plate is slidably connected in the cavity, the other end of the top shaft is fixedly connected to the surface of the push plate, a threaded shaft is connected in the push plate by a thread, the other end of the threaded shaft passes through the side wall of the cavity for rotational connection, and a knob is fixedly connected at the end, and the knob surface is provided with anti-slip grooves,

[0010] By buckling the "U"-shaped top plate on the surface of the fixing frame, a gap between the fixing frame and the top plate can be avoided, which would cause a joint seam on the carbon fiber plate. At the same time, because the top surface of the top plate is concave, when the spring drives the top plate to move downward, the top plate will be flattened until it is completely fitted on the surface of the step groove. At the same time, when the sliding shaft slides upward, the top plate will be reset. Since the top surface is arc-shaped, the distance between the corners of the two short arms will be shortened during reset, making the contact area between the top plate and the carbon fiber plate smaller and easier to disengage. By rotating the threaded shaft, the push plate can be driven to drive the two top shafts to move in the direction close to the sliding shaft at the same time. The threaded shaft can make the top plate lift up at a very slow speed to avoid damage to the carbon fiber plate caused by sudden lifting. The anti-slip texture on the surface of the knob can increase the friction of the staff's palm to avoid slipping.

[0011] Furthermore, a plurality of positioning holes are provided on the surface of the fixing frame, and the positioning pin passes through the pressure plate and is installed in the positioning hole. The bottom of the positioning pin is rotatably connected to a spring piece through a torsion spring, and the spring piece is in a "V" shape, and the two arms of the spring piece have different lengths. The inner wall of the positioning pin is provided with a slot relative to the position of the spring piece, and the long arm end of the spring piece is rotatably connected to a rotating wheel. When the positioning pin is installed into the positioning hole, when the positioning pin is about to reach the bottom of the positioning hole, the long arm end of the spring piece will touch the bottom and rotate, driving the short arm end of the spring piece to be stuck in the slot, further positioning the positioning pin to avoid falling off, causing the carbon fiber plate to shake and affecting molding. The rotating wheel can reduce the friction between the spring piece and the bottom surface of the positioning hole, and can also assist in the installation of the positioning pin.

[0012] Compared with the prior art, the utility model can effectively avoid the situation where the mold and the product are tightly attached together due to pressure through the cooperation of the top plate, the fixing block and the pressure plate, so that the finished product and the mold can be separated intact, thereby improving the yield rate. At the same time, the product can be separated vertically from the mold without getting stuck with the mold, and it is safe and reliable to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] Example:

[0023] according to Figure 1-6 As shown, a carbon fiber Z-shaped wall panel forming tool comprises a bottom plate 1, which is used to install a fixing frame 3 and carry a carbon fiber plate 4 to extrude the carbon fiber plate 4 into shape;

[0024] It also includes a positioning assembly, a fixing frame 3 and a carbon fiber plate 4;

[0025] The fixing frame 3 is fixedly mounted on the surface of the bottom plate 1 by means of bolts, and a carbon fiber plate 4 is fixedly mounted on the surface of the fixing frame 3 by means of a positioning assembly;

[0026] The positioning assembly includes a positioning pin 5 and a pressing plate 2, the pressing plate 2 is in an "L" shape, and the carbon fiber plate 4 is placed under the pressing plate 2 and is pressurized by a vacuum bag;

[0027] The surface of the fixing frame 3 is provided with a step groove 6, and a top plate 7 is clamped on the surface of the step groove 6. A sliding shaft 9 is fixedly connected to the other side of the top plate 7. A through hole 10 is provided on the surface of the fixing frame 3. The sliding shaft 9 is slidably connected in the through hole 10 by a spring. A top shaft 12 is slidably connected in the fixing frame 3. An oblique angle is provided on the surface of the top shaft 12. An arc angle is provided on the bottom surface of the sliding shaft 9 relative to the oblique angle of the surface of the top shaft 12. When working, the carbon fiber plate 4 to be formed is placed on the surface of the fixing block, and then the carbon fiber plate 4 is positioned by the positioning component, and then the entire device is placed in a vacuum bag for vacuuming. The empty bag is pressurized and formed. After the carbon fiber plate 4 is processed and formed, the top shaft 12 is pushed toward the sliding shaft 9 so that the oblique angle of the top shaft 12 squeezes the arc surface of the sliding shaft 9, causing the sliding shaft 9 to slide upward and drive the top plate 7 to move, so that the top plate 7 lifts up the carbon fiber plate 4 on the surface of the fixed frame 3 and separates it. After releasing, the spring drives the top plate 7 to reset. Through the cooperation of the top plate 7, the fixed block and the pressure plate 2, the situation where the mold and the product are tightly attached together due to pressure can be effectively avoided, so that the finished product can be separated from the mold intactly, thereby improving the yield rate and having the advantages of convenient disassembly and assembly, safety and reliability.

[0028] The top plate 7 is in an inverted "U" shape and has elasticity. A step groove 6 is provided on the surface of the fixing frame 3. The top plate 7 is sleeved on the surface of the step groove 6, and the surfaces of the two short arm ends of the top plate 7 are provided with bevels. The long arm end of the top plate 7 is an arc shape that is recessed toward the fixing frame 3. The sliding shaft 9 is provided with two groups, and each group has two, and is symmetrically distributed with respect to the longitudinal and transverse midlines of the top plate 7. A cavity 11 is provided in the fixing frame 3, and a push plate 13 is slidably connected in the cavity 11. The other end of the top shaft 12 is fixedly connected to the surface of the push plate 13. A threaded shaft 14 is connected in the push plate 13 by a thread. The other end of the threaded shaft 14 passes through the side wall of the cavity 11 for rotational connection, and a knob 8 is fixedly connected to the end, and the surface of the knob 8 is provided with anti-slip grooves.

[0029] When working, by buckling the top plate 7 in the shape of U on the surface of the fixing frame 3, a gap between the fixing frame 3 and the top plate 7 can be avoided, which leads to a splicing seam on the carbon fiber plate 4. At the same time, because the top surface of the top plate 7 is a concave design, when the spring drives the top plate 7 to move downward, the top plate 7 will be flattened until it is completely fitted on the surface of the step groove 6. At the same time, when the sliding shaft 9 slides upward, the top plate 7 will be reset. Because the top surface is arc-shaped, the distance between the corners of the two short arm ends will be shortened during reset, making the contact area between the top plate 7 and the carbon fiber plate 4 smaller and more convenient to disengage. By rotating the threaded shaft 14, the push plate 13 can be driven, so that the push plate 13 drives the two top shafts 12 to move in the direction close to the sliding shaft 9 at the same time. The threaded shaft 14 can make the top plate 7 rise slowly, avoiding damage to the carbon fiber plate 4 caused by sudden rise, and the anti-skid pattern on the surface of the knob 8 can increase the friction of the palm of the staff to avoid slipping.

[0030] A plurality of positioning holes 18 are provided on the surface of the fixing frame 3, and the positioning pin 5 passes through the pressure plate 2 and is installed in the positioning hole 18. The bottom of the positioning pin 5 is rotatably connected with a spring 16 through a torsion spring. The spring 16 is in a "V" shape, and the two arms of the spring 16 are of different lengths. The inner wall of the positioning pin 5 is provided with a slot 15 relative to the position of the spring 16, and the long arm end of the spring 16 is rotatably connected with a rotating wheel 17; during operation, when the positioning pin 5 is installed into the positioning hole 18, when the positioning pin 5 is about to reach the bottom of the positioning hole 18, the long arm end of the spring 16 will touch the bottom and rotate, driving the short arm end of the spring 16 to be stuck in the slot, further positioning the positioning pin 5 to avoid falling off, causing the carbon fiber plate 4 to shake, affecting the molding, and the friction between the spring 16 and the bottom surface of the positioning hole 18 can be reduced by the rotating wheel 17, and the installation of the positioning pin 5 can also be assisted.
