Description

Technical Field

[0001] This invention relates to the field of composite material processing technology, specifically a stabilizing device for a composite material pultrusion die. Background Technology

[0002] Composite materials are made of two or more materials with different properties, combined macroscopically or microscopically through physical or chemical methods to create materials with new properties. The various materials complement each other in terms of performance, producing a synergistic effect, so that the comprehensive performance of the composite material is superior to that of the original constituent materials and meets various requirements. The matrix materials of composite materials are divided into two main categories: metals and non-metals. During the output process of composite material parts after pultrusion molding, they need to be pulled by traction equipment. At present, when pulling composite material parts, rollers are mainly used to press down and rotate to push them out. This is prone to deviation or swaying, causing deformation or even bending. The output process is not stable and it is difficult to ensure the smooth output of composite material parts. In addition, the contact area between the rollers and the composite material parts is small, and the surface of the composite material parts is easily deformed due to the extrusion action.

[0003] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a stabilizing device for composite material pultrusion molds, which solves the problems of easy deviation or swaying during the traction of composite material parts, resulting in deformation or even bending, poor output stability, difficulty in ensuring smooth and stable output of composite material parts, and small contact area between rollers and composite material parts, which easily causes surface deformation of composite material parts due to extrusion.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A stabilizing device for a composite material pultrusion die includes a composite material processing table, a pultrusion die, and a preforming die. A stabilizing mounting base is welded and fixed to the top of the composite material processing table. The pultrusion die and the preforming die are fixedly mounted on the top of a die support plate. A stabilizing support plate is provided above the stabilizing mounting base. The stabilizing mounting base is hollow inside and a limiting pressure plate is slidably installed inside. Multiple sets of auxiliary stabilizing and bearing components are installed between the bottom of the limiting pressure plate and the inner bottom of the stabilizing mounting base. The die support plate is located above the stabilizing support plate, and a lifting and docking electric cylinder connected to the bottom of the die support plate is fixedly installed on the top of the stabilizing support plate.

[0007] The top of the stable support plate is fixed with a mounting bracket by bolts. The front and rear sides of the top of the mounting bracket are fixed with transverse fixing plates. Multiple sets of bearing rollers are rotatably arranged between the two sets of transverse fixing plates in the X direction. The bearing rollers support the composite material processing part that passes through the pultrusion mold. A stabilizing anti-displacement component is installed between the two sets of transverse fixing plates, and the composite material processing part passes through the stabilizing anti-displacement component.

The inner wall of the lower slot is provided with passive damping protrusions at equal intervals along the vertical direction, and the outer periphery of the lower insertion rod is provided with active damping protrusions.

[0012] Multiple sets of mounting blocks are fixedly installed on the outer circumferential surface of the vertical column. A connecting rod is correspondingly installed at the bottom of the pressing head, and the connecting rod passes downward through the corresponding mounting block. A stabilizing spring is sleeved on the outer circumferential surface of the connecting rod, and the stabilizing spring is fixedly connected to the pressing head and the mounting block.

[0013] Furthermore, the stable traction pultrusion assembly includes a pultruded track and a mounting box. The mounting box is fixedly connected to the bottom end of the telescopic adjustment electric cylinder. The area enclosed by the pultruded track is in the shape of an isosceles trapezoid. The upper horizontal plane of the pultruded track is located inside the mounting box, and the lower horizontal plane of the pultruded track is located below the mounting box. Openings for the pultruded track to pass through are provided on both sides of the bottom of the mounting box.

[0014] Furthermore, drive track wheels are installed on both sides near the top inside the mounting box. A push motor is fixedly installed inside the mounting box via a motor mount, and the output end of the push motor is connected to one of the drive track wheels. A pressing expansion mechanism is fixedly installed at the bottom of the mounting box, and the pressing expansion mechanism presses down on the top two sides of the lower horizontal surface of the pultruded track. The lower horizontal surface of the pultruded track contacts the upper part of the composite material processing part, and the pressing pultrusion mechanism is evenly distributed on the outer surface of the pultruded track.

[0015] Furthermore, the downward expansion mechanism includes an expansion mechanism mounting plate fixedly installed at the bottom of the mounting box by bolts. A downward pressure plate is provided at the center of the lower part of the expansion mechanism mounting plate, and a vertical guide rod is fixedly installed at the bottom of the expansion mechanism mounting plate, extending downward through the downward pressure plate. The bottom ends of the vertical guide rods are connected by rods, and a tension spring is sleeved on the outer circumference of the vertical guide rod and fixedly connected to the bottom of the downward pressure plate.

[0016] The bottom two sides of the expansion mechanism mounting plate are fixedly provided with downward-facing vertical cylinders. The vertical cylinders are equipped with downward-extending upper insert rods. The bottom of the upper insert rods is equipped with a lower pressing track wheel through a connecting seat.

A connecting block is fixedly provided on the outer peripheral surface of the upper insert rod near the top. The outer peripheral surface of the vertical cylinder is provided with a vertical opening for the connecting block to pass through. The two sides of the lower pressing plate are movably connected with inclined push rods. The side of the inclined push rod away from the lower pressing plate is inclined downward and connected to the corresponding connecting block.

[0017] Furthermore, the downward pressing pultrusion mechanism includes an elastic inner hollow block installed on the outer surface of the pultrusion track.

The fixing block extends out of the elastic inner hollow block and is fixedly connected to the pultrusion bonding block. The surface of the pultrusion bonding block is uniformly provided with anti-slip and wear-resistant textures.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the bottom of the composite material part is supported by the bearing roller to support it and reduce the frictional resistance at the bottom of the composite material part. The opposite sides of the two sets of anti-deviation horizontal plates in the anti-deviation assembly are in contact with the composite material part. The friction-reducing ball effectively reduces the frictional resistance of the anti-deviation horizontal plates on the composite material part, guides the output process of the composite material part, and makes the composite material part output in a straight path. This effectively avoids deviation or swaying when the composite material part is output, prevents deformation or bending of the composite material part, and ensures the smooth and stable output of the composite material part.

[0020] 2. In this invention, the lower horizontal surface of the pultruded track in the stable traction pultrusion assembly contacts the upper part of the composite material processing part, which expands the contact area with the composite material processing part and solves the problem that the surface of the composite material processing part is easily deformed or damaged due to extrusion during the output process. The downward expansion mechanism acts on the pultruded track to keep the lower horizontal surface of the pultruded track horizontal and effectively fits the upper part of the composite material processing part, ensuring the subsequent traction pultrusion pushing of the composite material processing part.

[0021] 3. In this invention, by installing multiple sets of downward pultrusion mechanisms on the outer surface of the pultruded track, the compression spring in the downward pultrusion mechanism applies downward pressure to the downward moving block, and the downward moving block applies downward pressure to the pultruded bonding block through the fixed block, thereby making the pultruded bonding block tightly press against the upper part of the composite material processing part, increasing the traction force on the composite material processing part, which helps to traction and push the composite material processing part.

[0022] 4. In this invention, the vibration generated by the stabilizing support plate is buffered by the auxiliary stabilizing bearing component, which helps to stabilize the support plate and plays an auxiliary role in ensuring the stability of the processing operation of composite material parts. The repeated friction between the active damping protrusion and the passive damping protrusion plays a damping role, reducing the vibration of the stabilizing support plate. By combining stabilizing support, guiding and anti-displacement and downward pushing, the stability of the pultrusion process is ensured, effectively preventing the deformation of composite material parts caused by displacement, vibration and extrusion, and improving the quality of the processed products.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] like Figure 1-5 As shown, the present invention proposes a stabilizing device for a composite material pultrusion die, including a composite material processing table 1, a pultrusion die 2, and a preforming die 3. The preforming die 3 preforms the composite material part, and the pultrusion die 2 pultrudes the composite material part. A stabilizing mounting base 14 is welded and fixed to the top of the composite material processing table 1, and the pultrusion die 2 and the preforming die 3 are fixedly set on the top of the die support plate 15. A stabilizing support plate 13 is provided above the stabilizing mounting base 14, and the die support plate 15 is located above the stabilizing support plate 13. A lifting and docking electric cylinder 16 connected to the bottom of the die support plate 15 is fixedly set on the top of the stabilizing support plate 13. The lifting and docking electric cylinder 16 can adjust the height of the die support plate 15 by extending or shortening, so as to facilitate the smooth output of the pultruded composite material part as needed.

[0036] A fixed plate mounting bracket 10 is bolted to the top of the stable support plate 13. Horizontal fixed plates 6 are fixed to the front and rear sides of the top of the fixed plate mounting bracket 10. Multiple sets of bearing rollers 7 are rotatably arranged between the two sets of horizontal fixed plates 6 along the X-direction. The bearing rollers 7 support the composite material processing part passing through the pultrusion mold 2, effectively reducing the frictional resistance experienced by the bottom of the composite material processing part during output. A stable anti-deviation component 4 is installed between the two sets of horizontal fixed plates 6. Specifically, the stable anti-deviation component 4 includes two sets of anti-deviation horizontal plates 41 located between the two sets of horizontal fixed plates 6. The composite material processing part passes between the two sets of anti-deviation horizontal plates 41 and contacts the inner wall of the anti-deviation horizontal plates 41. Preferably, multiple sets of drag-reducing balls 45 are rolled on opposite sides of the two sets of anti-deviation horizontal plates 41. The drag-reducing balls 45 effectively reduce the frictional resistance of the anti-deviation horizontal plates 41 on the composite material processing part, further ensuring the stable and smooth output of the composite material processing part.

[0037] Two sets of adjustable bidirectional screws 44 are rotatably mounted on the transverse fixed plate 6 via bearings. The threads of the two ends of the adjustable bidirectional screws 44 have opposite directions with their midpoints as the boundary. A drive motor 46 for adjusting the pitch is fixedly mounted on one set of transverse fixed plates 6 via a motor mount, and the output end of the drive motor 46 is connected to one set of adjustable bidirectional screws 44. The two sets of adjustable bidirectional screws 44 are connected by a synchronous belt 47. Two anti-deviation horizontal plates 41 are symmetrical about the midpoint of the adjustable bidirectional screws 44. A lower mounting rod 42 is fixedly mounted at the bottom of the anti-deviation horizontal plate 41. The bottom end of the rod 42 is fixedly equipped with a longitudinal sliding sleeve 43 that is threadedly connected to the adjustable pitch bidirectional screw 44. The adjustable pitch motor 46 drives the corresponding adjustable pitch bidirectional screw 44 to rotate. The synchronous belt 47 makes the two sets of adjustable pitch bidirectional screws 44 rotate synchronously, and the corresponding two sets of longitudinal sliding sleeves 43 move towards each other. Thus, the distance between the two sets of anti-deviation horizontal plates 41 is continuously reduced by the lower mounting rod 42 until the opposite side of the two sets of anti-deviation horizontal plates 41 contacts the composite material processing part, which facilitates adjustment and is suitable for composite material processing parts of different specifications and sizes.

[0038] A fixed bearing column 8 is fixedly installed on the horizontal fixed plate 6 located at the rear. The fixed bearing column 8 extends upward and a horizontal mounting plate 11 is fixedly installed on its top. A stable traction pultrusion assembly 5 is provided below the horizontal mounting plate 11, and a telescopic adjustment electric cylinder 12 is fixedly installed at the bottom of the horizontal mounting plate 11. The telescopic adjustment electric cylinder 12 can adjust the height of the stable traction pultrusion assembly 5 by extending or shortening. Specifically, the stable traction pultrusion assembly 5 includes a pultruded track 51 and a mounting box 52. The mounting box 52 is fixedly connected to the bottom end of the telescopic adjustment electric cylinder 12. The area enclosed by the pultruded track 51 is in the shape of an isosceles trapezoid. The upper horizontal surface of the pultruded track 51 is located inside the mounting box 52, and the lower horizontal surface of the pultruded track 51 is located below the mounting box 52. Openings are provided on both sides of the bottom of the mounting box 52 for the pultruded track 51 to pass through.

[0039] Drive track wheels 56 are installed on both sides near the top inside the mounting box 52. A push motor 55 is fixedly installed inside the mounting box 52 via a motor mount, and the output end of the push motor 55 is connected to one of the drive track wheels 56. During operation, the push motor 55 causes the corresponding drive track wheel 56 to rotate, and the pultruded track 51 moves accordingly. Under the pushing action of the pultruded track 51, the output of the composite material processing part is pulled, which significantly increases the contact area of ​​the composite material processing part during the traction and pushing process, reduces the damage to the composite material processing part caused by the roller extrusion traction, and ensures the stability of the traction output process. A pressing expansion mechanism 53 is fixedly installed at the bottom of the mounting box 52, and the pressing expansion mechanism 53 presses down on the top two sides of the lower horizontal surface of the pultruded track 51, and the lower horizontal surface of the pultruded track 51 contacts the upper part of the composite material processing part.

[0040] Specifically, the downward expansion mechanism 53 includes an expansion mechanism mounting plate 531, which is fixedly mounted on the bottom of the mounting box 52 by bolts. A downward pressure plate 532 is provided at the center of the lower part of the expansion mechanism mounting plate 531, and a vertical guide rod 537 is fixedly provided at the bottom of the expansion mechanism mounting plate 531, extending downward through the downward pressure plate 532. The bottom ends of the vertical guide rods 537 are connected by rods, and a tension spring 538 is sleeved on the outer periphery of the vertical guide rods 537 and fixedly connected to the bottom of the downward pressure plate 532. The tension spring 538 applies downward pressure to the downward pressure plate 532. Vertical cylinders 534 are fixedly provided on both sides of the bottom of the expansion mechanism mounting plate 531. The openings of the vertical cylinders 534 face downward, and an upper insert rod 535 extending downward is installed inside the vertical cylinder 534. A downward pressure track wheel 536 is installed at the bottom of the upper insert rod 535 through a connecting seat, and the downward pressure track wheel 536 presses down on the top two sides of the lower horizontal surface of the pultruded track 51.

[0041] A connecting block 539 is fixedly installed on the outer peripheral surface near the top of the upper insertion rod 535, and a vertical opening is correspondingly opened on the outer peripheral surface of the vertical cylinder 534 for the connecting block 539 to pass through. An inclined push rod 533 is movably connected to both sides of the lower pressure plate 532, and the side of the inclined push rod 533 away from the lower pressure plate 532 is inclined downward and connected to the corresponding connecting block 539. The lower pressure plate 532 applies a downward pushing force to the upper insertion rod 535 through the two sets of inclined push rods 533 and the connecting block 539. The two sets of lower pressing track wheels 536 are subjected to downward pressure and act on the pultruded track 51 to keep the lower horizontal surface of the pultruded track 51 horizontal and effectively fit with the upper part of the composite material processing part, ensuring the subsequent traction and pultrusion pushing of the composite material processing part.

[0042] Example 2:

[0043] like Figure 1 and Figure 6-7 As shown, the difference between this embodiment and embodiment 1 is that the interior of the stable mounting base 14 is hollow and a limiting pressure plate 17 is slidably installed inside. Multiple sets of auxiliary stabilizing bearing components 9 are installed between the bottom of the limiting pressure plate 17 and the inner bottom of the stable mounting base 14. Specifically, the auxiliary stabilizing bearing components 9 include a vertical column 91 and a lower pressure head 92. The vertical column 91 is fixedly installed at the inner bottom of the stable mounting base 14, and the lower pressure head 92 is fixedly installed at the bottom of the limiting pressure plate 17. The vertical column 91 has an upward-facing lower slot 98, and the bottom of the lower pressure head 92 is fixedly provided with a lower insertion rod 96, which is inserted downward into the corresponding lower slot 98.

[0044] Multiple sets of mounting blocks 93 are fixedly installed on the outer periphery of the vertical column 91. A connecting rod 95 is correspondingly installed at the bottom of the pressing head 92, and the connecting rod 95 passes downward through the corresponding mounting block 93. A stabilizing spring 94 is sleeved on the outer periphery of the connecting rod 95, and the stabilizing spring 94 is vertically installed and fixedly connected to the pressing head 92 and the mounting block 93. During the processing, when vibration occurs, the distance between the pressing head 92 and the vertical column 91 changes continuously, and the deformation degree of the stabilizing spring 94 changes continuously, which buffers the vibration generated by the stabilizing support plate 13, helps to stabilize the support plate 13, and helps to stabilize the processing operation of composite material parts.

[0045] Preferably, passive damping protrusions 99 are equidistantly arranged on the inner wall of the lower slot 98 along the vertical direction, and active damping protrusions 97 are correspondingly arranged on the outer periphery of the lower insert rod 96. When vibration occurs, the active damping protrusions 97 and the passive damping protrusions 99 rub against each other repeatedly, playing a damping role, thereby reducing the vibration degree of the stable support plate 13 and further ensuring the stable support of the stable support plate 13. By combining stable support, guiding anti-displacement and downward pushing, the stability of the pultrusion process is ensured, effectively preventing deformation of composite material parts caused by displacement, vibration and extrusion, and improving the quality of the processed products.

[0046] Example 3:

[0047] like Figure 4 and Figure 8 As shown, the difference between this embodiment and Embodiments 1 and 2 is that a downward pressing pultrusion mechanism 54 is uniformly arranged on the outer surface of the pultruded track 51. Specifically, the downward pressing pultrusion mechanism 54 includes an elastic inner hollow block 541, which is installed on the outer surface of the pultruded track 51. The elastic inner hollow block 541 is detachable, and a downward pressing movable block 545 is movably installed inside the elastic inner hollow block 541. A compression spring 544 is fixedly installed inside the elastic inner hollow block 541, and the other end of the compression spring 544 is fixedly connected to the downward pressing movable block 545. A fixing block 542 is provided on the side of the downward pressing movable block 545 facing away from the compression spring 544. The fixing block 542 protrudes through the elastic inner hollow block 541, and the side of the fixing block 542 protruding through the elastic inner hollow block 541 is fixedly connected to the pultruded bonding block 543.

[0048] During the processing of composite material parts, when the pultruded bonding block 543 contacts the upper part of the composite material part, the compression spring 544 is in a compressed state and applies downward pressure to the pressing movable block 545. The pressing movable block 545 applies downward pressure to the pultruded bonding block 543 through the fixed block 542, thereby making the pultruded bonding block 543 press tightly against the upper part of the composite material part, increasing the traction force on the composite material part, which helps to pull and push the composite material part. Preferably, the surface of the pultruded bonding block 543 is uniformly provided with anti-slip and wear-resistant textures, which further increases the friction between it and the composite material part, which helps to pull the composite material part smoothly.

[0049] The working principle of this invention is as follows: In use, the output side of the pultruded composite material part enters between two sets of transverse fixing plates 6. The bearing roller 7 supports the bottom of the composite material part. The drive pitch motor 46 in the stabilizing anti-deviation assembly 4 causes the corresponding pitch-adjusting bidirectional screw 44 to rotate. The synchronous belt 47 causes the two sets of pitch-adjusting bidirectional screws 44 to rotate synchronously. The corresponding two sets of longitudinal sliding sleeves 43 move towards each other. Thus, the distance between the two sets of anti-deviation horizontal plates 41 is continuously reduced by the lower mounting rod 42 until the opposite side of the two sets of anti-deviation horizontal plates 41 contacts the composite material part. This guides the output process of the composite material part, making the composite material part output in a straight path. This effectively avoids deviation or swaying during the output of the composite material part, prevents deformation or bending of the composite material part, and ensures smooth output of the composite material part. In addition, the friction-reducing ball 45 can effectively reduce the frictional resistance of the anti-deviation horizontal plate 41 on the composite material part, further ensuring the stable and smooth output of the composite material part.

[0050] During the output process of the composite material processing part, the telescopic adjustment electric cylinder 12 extends and lowers the stable traction pultrusion assembly 5 until the lower horizontal surface of the pultrusion track 51 in the stable traction pultrusion assembly 5 contacts the upper part of the composite material processing part, thus expanding the contact area with the composite material processing part. The tension spring 538 in the downward expansion mechanism 53 applies downward pressure to the lower pressure plate 532, thereby applying downward thrust to the upper insertion rod 535 through two sets of inclined push rods 533 and connecting blocks 539. The two sets of downward pressing track wheels 536 are subjected to downward pressure and act on the pultrusion track 51 to keep the lower horizontal surface of the pultrusion track 51 horizontal and effectively fit with the upper part of the composite material processing part, ensuring the subsequent traction pultrusion pushing of the composite material processing part.

[0051] Furthermore, during the traction and pushing process, the push motor 55 causes the corresponding drive track wheel 56 to rotate, and the pultrusion track 51 moves accordingly. Under the pushing action of the pultrusion track 51, the output of the composite material processing part is pulled. The bearing roller 7 not only plays a supporting role, but also effectively reduces the frictional resistance experienced by the bottom of the composite material processing part during the output process. This solves the problem that the current method of traction and pushing the composite material processing part by pressing it downward with guide wheels and rotating it has a small surface contact area between the guide wheels and the composite material processing part, which is prone to deformation or damage to the surface of the composite material processing part due to compression. This ensures the stability of the traction and pushing process of the composite material processing part. In addition, multiple sets of downward pressing pultrusion mechanisms 54 are installed on the outer surface of the pultrusion track 51. The compression spring 544 in the downward pressing pultrusion mechanism 54 applies downward pressure to the downward pressing movable block 545. The downward pressing movable block 545 applies downward pressure to the pultrusion bonding block 543 through the fixed block 542, thereby making the pultrusion bonding block 543 press tightly against the upper part of the composite material processing part, increasing the traction force on the composite material processing part and helping to traction and push the composite material processing part.
