Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber tube production equipment, and in particular to a carbon fiber tube forming device and a carbon fiber tube. Background Art

[0002] Carbon fiber is a microcrystalline graphite material obtained by carbonizing and graphitizing organic fibers. The microstructure of carbon fiber is similar to artificial graphite, which is a turbostratic graphite structure. Carbon fiber is a new material with excellent mechanical properties. The tensile strength of carbon fiber resin composite materials is generally above 3500Mpa, which is 7 to 9 times that of steel, and the tensile elastic modulus is 230-430Gpa. Therefore, the ratio of the material's strength to its density can reach more than 2000Mpa.

[0003] Aluminum alloy is a kind of nonferrous metal structural material with wide industrial application. It has high plasticity and good corrosion resistance and can be made into various pipes, profiles and plates. However, due to its heavy weight and poor shock absorption, aluminum alloy pipes are used in bicycle frames, photographic equipment and other occasions with high requirements for weight and shock resistance, which can easily affect bicycle performance and photographic effects. With the continuous development and evolution of carbon fiber composite material technology, carbon fiber composite pipes have gradually replaced aluminum alloy pipes and have been accepted by the market due to their advantages of light weight, high strength, good toughness and strong shock resistance.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 10 , the present invention provides a technical solution:

[0038] A carbon fiber tube forming device comprises a frame plate 2, a forming mechanism 3 is arranged on the left side of the inner side of the frame plate 2, and a primary roller 23 is rotatably connected to the upper front side of the inner side surface of the frame plate 2 through a roller shaft, a secondary roller 24 is symmetrically arranged on the left side of the primary roller 23, and a tension roller 5 is arranged below the position between the secondary roller 24 and the primary roller 23, a roller frame 1 is arranged on the front side of the frame plate 2, and a winding roller 12 is rotatably connected to the upper end of the inner side of the roller frame 1, and a carbon fiber cloth 11 is wound on the winding roller 12, and the carbon fiber cloth 11 is passed around the upper end surface of the primary roller 23, the lower end surface of the tension roller 5 and the upper end surface of the secondary roller 24 in sequence to the position of the forming mechanism 3.

[0040] As an embodiment of the present invention, Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the forming mechanism 3 includes a motor 31, a universal joint 32, a rotating rod 33, a movable ring 34, a primary hinge seat 35, an hinge rod 36, a secondary hinge seat 37, a template 38 and a fixed ring 39. The motor 31 is fixedly connected to the support plate on the outer side of the left frame plate 2, and the output shaft of the motor 31 passes through the left frame plate 2 and is fixedly connected to the left end of the universal joint 32. The right end of the universal joint 32 is fixedly connected to the left end of the rotating rod 33. The movable ring 34 is slidably sleeved on the left side of the rotating rod 33, and the fixed ring 39 is fixedly connected to the right side of the rotating rod 33. The movable ring 34 and the fixed ring 39 are fixedly connected to the right side of the rotating rod 33. The annular outer surface of the fixed ring 39 is annularly and equidistantly fixedly connected with four primary articulated seats 35, the template 38 is annularly and equidistantly arranged on the outside of the rotating rod 33 corresponding to the primary articulated seats 35, and the inner side of the template 38 is fixedly connected with secondary articulated seats 37, one end of the articulated rod 36 is hinged to the primary articulated seat 35, and the other end is hinged to the secondary articulated seat 37, a sliding groove 71 is provided on the upper end surface of the rotating rod 33 below the movable ring 34, and the movable ring 34 is located on the inner side corresponding to the sliding groove 71 and fixedly connected with a slider 72, and the rotating rod 33 on the right side near the sliding groove 71 is fixedly connected with a slider 72. The electric push rod 7 is connected, and the left end of the electric push rod 7 is fixedly connected to the right side of the movable ring 34. The right end of the rotating rod 33 is sleeved with a rotating shaft 4, and the right end of the rotating shaft 4 is rotatably connected to the inner side of the right frame plate 2. The cross-section of the template 38 is an isosceles right triangle structure, and the hypotenuse of the isosceles right triangle corresponds to the rotating rod 33. The left outer surface of the rotating shaft 4 is annularly equidistantly provided with six semicircular groove structures. The left side of the rotating shaft 4 is slidably sleeved with a sleeve 42, and the inner side of the sleeve 42 is fixedly connected with a block 43 matching the slot 41. Six grooves 41 are equidistantly provided in a circular shape on the outer surface of the right side of the rotating rod 33, and a spring groove 44 penetrating the block 43 is equidistantly provided in a circular shape inside the left side of the sleeve 42 corresponding to the block 43, and a primary spring 45 is provided in the spring groove 44, the head of the primary spring 45 is fixedly connected to the inner bottom of the spring groove 44, and the tail of the primary spring 45 is fixedly connected to a limiting pin 46, the tail of the limiting pin 46 is placed in the spring groove 44, and the head of the limiting pin 46 is a hemispherical structure, and a limiting groove 47 with a semicircular groove structure is provided in the inner bottom of the groove 41 on the right side of the rotating rod 33.

[0041] During operation, the sleeve 42 is pulled to the left, and the block 43 slides into the slot 41 on the right side of the rotating rod 33 along the slot 41 on the rotating shaft 4. The limiting pin 46 in the spring slot 44 is ejected into the limiting slot 47 in the slot 41 at the right end of the rotating rod 33 under the action of the primary spring 45, thereby fixing the rotating rod 33 and the rotating shaft 4. First, a part of the left end of the carbon fiber cloth 11 is wound around the template 38, and then the motor 31 is started to drive the rotating rod 33 to rotate clockwise, so that the carbon fiber cloth 11 is continuously wound, thereby forming a carbon fiber tube. After the carbon fiber tube is formed, the motor 31 is turned off, and the sleeve 42 is slid to the right to make the carbon fiber cloth 11 be wound around the template 38. The rotating rod 33 is disengaged from the rotating shaft 4. Since the left end of the rotating rod 33 is fixedly connected to the right end of the universal joint 32, and the left end of the universal joint 32 is fixedly connected to the output shaft of the motor 31, the rotating rod 33 can rotate upward around the universal joint 32. Then, the electric push rod 7 is started to push the movable ring 34 to the left, thereby driving the template 38 to shrink inward to complete the separation from the carbon fiber tube, thereby facilitating the removal of the carbon fiber tube. When carbon fiber tubes of different sizes need to be manufactured, the movable ring 34 can be driven to move to the left or right by the electric push rod 7, thereby driving the template 38 to shrink or expand to obtain different sizes, thereby improving work efficiency.

[0042] As an embodiment of the present invention, Figure 3 , Figure 4 and Figure 7As shown, an extrusion mechanism 8 is provided at the left end of the inner side of the frame plate 2, and the extrusion mechanism 8 includes a fixed plate 81, a cylindrical tube 82, a secondary spring 83, a movable rod 84 and a pressure plate 85. The left and right sides of the fixed plate 81 are respectively fixedly connected to the inner side surface of the frame plate 2, and the cylindrical tube 82 is fixedly connected with three horizontally equidistant central positions on the front side surface of the fixed plate 81. The rear end of the secondary spring 83 is fixedly connected to the inner bottom of the cylinder hole of the cylindrical tube 82, and the front end thereof is fixedly connected to the rear end surface of the movable rod 84. The rear end of the movable rod 84 is placed in the cylinder hole of the cylindrical tube 82, and the front end of the movable rod 84 is fixedly connected to the rear side surface of the pressure plate 85, and the front side of the pressure plate 85 is a semi-cylindrical structure. The upper end surfaces of the frame plates 2 on the left and right sides of the primary roller 23 are provided with a barrel 21, and a magnetic material is provided at the lower end opening of the barrel 21. The sealing plate 211 is formed, and the right end of the sealing plate 211 is hinged to the opening. Twelve rectangular grooves 233 are equidistantly provided in a ring shape on the outer edge of the primary roller 23. Six opposite magnets 231 and six like magnets 232 are fixedly connected in the rectangular grooves 233, and the opposite magnets 231 and the like magnets 232 are staggered with each other. Slots 22 are provided on the frame plates 2 on the left and right sides of the tension roller 5, and a fixed shaft 51 is rotatably connected to the center position of the tension roller 5. The left and right ends of the fixed shaft 51 are placed inside the slot 22. A screw hole 53 is provided on the upper end of the slot 22 and passes through the top of the frame plate 2. Threaded rods 52 are threadedly connected in the screw holes 53, and the lower ends of the threaded rods 52 are rotatably connected to the ends of the fixed shaft 51 through bearings. A cylinder 6 is provided below the tension roller 5, and a cutter 61 is fixedly connected to the upper end of the telescopic rod of the cylinder 6.

[0043] During operation, based on the above embodiment, the primary roller 23 will continuously rotate in the process of conveying the carbon fiber cloth 11. When the opposite-pole magnets 231 are opposite to the sealing plate 211, an attractive force is generated on the sealing plate 211. Since the right end of the sealing plate 211 is hinged to the right side of the lower end opening of the barrel 21, the left side of the sealing plate 211 moves downward to open the lower end opening of the barrel 21, and the adhesive in the barrel 21 flows onto the carbon fiber cloth 11. When the like-pole magnets 232 are opposite to the sealing plate 211, a repulsive force is generated on the sealing plate 211, thereby closing the sealing plate 211, and the adhesive stops flowing out, thereby forming an intermittent addition of adhesive to prevent waste caused by excessive addition of adhesive. When the carbon fiber cloth 11 passes through the lower end of the tension roller 5, the tension roller 5 can smooth the adhesive on the carbon fiber cloth 11 so that the adhesive is evenly applied, and then it is wound onto the template 38 through the secondary roller 24. As the template 38 continues to rotate, the pressing plate 85 The carbon fiber cloth 11 on the left side of the template 38 is continuously squeezed to exhaust the air between the carbon fiber cloths 11, so that the carbon fiber cloths 11 are tightly fitted. As the thickness of the carbon fiber tube continues to increase, the movable rod 84 will compress the secondary spring 83 backward, so that the pressure plate 85 and the outer side of the carbon fiber tube are always in an extruded state to ensure the quality of the carbon fiber tube. When the tension of the carbon fiber cloth 11 is too large or too small during the transmission process, the fixed shaft 51 can be driven to descend or rise by rotating the threaded rod 52, thereby driving the tension roller 5 to move downward or upward to adjust the tension of the carbon fiber cloth 11, so as to avoid the carbon fiber cloth 11 from being too small to cause the forming of the carbon fiber tube, and too large tension to easily break the carbon fiber cloth 11 and affect the efficiency of the carbon fiber tube. When the carbon fiber tube is about to be formed, the cylinder 6 is started to drive the cutter 61 to move upward to cut the carbon fiber cloth 11 at the lower end face of the tension roller 5, thereby completing the forming of the carbon fiber tube.

[0044] As an embodiment of the present invention, Figures 1 to 10 As shown, a carbon fiber tube with a square cross-section is prepared by any one of the carbon fiber tube forming devices described above.

[0045] During operation, based on the above embodiment, as the motor 31 drives the template 38 to continuously rotate, the carbon fiber cloth 11 on the roller 12 is continuously wound onto the four templates 38. Since the cross-section of the template 38 is an isosceles right triangle structure, and the hypotenuse of the isosceles right triangle corresponds to the rotating rod 33, a carbon fiber tube with a square cross-section is formed.

[0046] Working principle: The carbon fiber cloth 11 passes by the upper end surface of the first roller 23, the lower end surface of the tension roller 5 and the upper end surface of the second roller 24 in turn to the position of the forming mechanism 3, and the sleeve 42 is pulled to the left. The block 43 slides into the slot 41 on the right side of the rotating rod 33 along the slot 41 on the rotating shaft 4. The limit pin 46 in the spring slot 44 is bounced into the limit slot 47 in the slot 41 at the right end of the rotating rod 33 under the action of the first spring 45, thereby fixing the rotating rod 33 and the rotating shaft 4. First, a part of the left end of the carbon fiber cloth 11 is wound around the template 38, and then the motor 31 is started to drive the rotating rod 33 to rotate clockwise, so that the carbon fiber cloth 11 is continuously wound, so as to form a carbon fiber tube. After the carbon fiber tube is formed, the motor 31 is turned off, and the sleeve 42 is slid to the right to make The rotating rod 33 is separated from the rotating shaft 4. Since the left end of the rotating rod 33 is fixedly connected to the right end of the universal joint 32, and the left end of the universal joint 32 is fixedly connected to the output shaft of the motor 31, the rotating rod 33 can rotate upward around the universal joint 32, and then the electric push rod 7 is started to push the movable ring 34 to the left, thereby driving the template 38 to shrink inward to complete the separation from the carbon fiber tube, thereby facilitating the removal of the carbon fiber tube. When it is necessary to manufacture carbon fiber tubes of different sizes, the movable ring 34 can be driven to move left or right by the electric push rod 7, thereby driving the template 38 to shrink or expand to obtain different sizes, thereby improving work efficiency. The primary roller 23 will continue to rotate during the transmission of the carbon fiber cloth 11. When the opposite magnet 231 is opposite to the sealing plate 211, the sealing plate 21 1 generates an attractive force. Since the right end of the sealing plate 211 is hinged to the right side of the lower end opening of the barrel 21, the left side of the sealing plate 211 moves downward to open the lower end opening of the barrel 21. The adhesive in the barrel 21 flows onto the carbon fiber cloth 11. When the same-sense magnet 232 is opposite to the sealing plate 211, a repulsive force is generated on the sealing plate 211, thereby closing the sealing plate 211, and the adhesive stops flowing out, thereby forming an interval-type adhesive addition to prevent waste caused by excessive adhesive addition. When the carbon fiber cloth 11 passes through the lower end of the tension roller 5, the tension roller 5 can smooth the adhesive on the carbon fiber cloth 11 so that the adhesive is evenly applied, and then it is wound onto the template 38 through the secondary roller 24. As the template 38 continues to rotate, the pressing plate 85 passes through the left side of the template 38. The carbon fiber cloth 11 is continuously squeezed to exhaust the air between the carbon fiber cloths 11, so that the carbon fiber cloths 11 are tightly fitted. As the thickness of the carbon fiber tube increases, the movable rod 84 will compress the secondary spring 83 backward, so that the pressure plate 85 and the outer side of the carbon fiber tube are always in a squeezed state to ensure the quality of the carbon fiber tube. When the tension of the carbon fiber cloth 11 is too large or too small during the transmission process, the fixed shaft 51 can be driven to descend or rise by rotating the threaded rod 52, thereby driving the tension roller 5 to move downward or upward to adjust the tension of the carbon fiber cloth 11, so as to avoid the carbon fiber cloth 11 from being too small to cause the carbon fiber tube to be formed, and too large tension to easily break the carbon fiber cloth 11 and affect the efficiency of the carbon fiber tube. When the carbon fiber tube is about to be formed,The start cylinder 6 drives the cutter 61 to move upward, thereby cutting the carbon fiber cloth 11 at the lower end surface of the tension roller 5, thereby completing the forming of the carbon fiber tube. When the motor 31 drives the template 38 to rotate continuously, the carbon fiber cloth 11 on the winding roller 12 is continuously wound onto the four templates 38. Since the cross section of the template 38 is an isosceles right triangle structure, and the hypotenuse of the isosceles right triangle corresponds to the rotating rod 33, a carbon fiber tube with a square cross section is formed.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
