Description

Technical Field

[0001] The utility model belongs to the technical field of pultrusion molding, and in particular relates to a composite material frame multi-mode pultrusion structure. Background Art

[0002] Fiber reinforced composites are composite materials formed by winding, molding or pultrusion of reinforcing fiber materials, such as glass fiber, carbon fiber, aramid fiber, basalt fiber, etc., with matrix materials. According to the different reinforcing materials, common fiber reinforced composites are divided into glass fiber reinforced composites (GFRP), carbon fiber reinforced composites (CFRP), aramid fiber reinforced composites (AFRP) and basalt fiber reinforced composites (CBF).

[0003] Glass fiber is a filament drawn from molten glass quickly. It can be divided into alkali, alkali-free, medium alkali and special glass fibers, such as high silica and quartz fibers, according to the raw material components. Commonly used glass fiber composite materials generally refer to resin (such as epoxy resin, phenolic resin, unsaturated polyethylene resin, etc.) based composite materials, which can be formed by hand lay-up, winding, pressing and other molding processes, or injection and pultrusion molding processes. Glass fiber reinforced composite materials can be widely used in manual machinery, chemical industry, transportation and other fields due to their light weight, corrosion resistance, insulation and other characteristics.

[0004] The pultrusion process of composite material profiles is to form and solidify continuous fiber composite materials of unlimited length through an extrusion die under the action of traction by continuous glass fiber bundles, tapes or cloth impregnated with resin glue. This process is most suitable for producing FRP profiles of various cross-sectional shapes, such as rods, tubes, solid profiles (I-shaped, grooved, square profiles) and hollow profiles (door and window profiles, blades), etc. Figure 1 The figure shows a schematic diagram of the pultrusion process.

[0005] The existing extrusion dies are arranged side by side in the workshop. On the one hand, they occupy a large area and have low utilization rate of the workshop space. On the other hand, when an extrusion die fails and needs maintenance, in order to ensure the safety of the maintenance process, 1-2 production lines nearby need to be shut down. Otherwise, the extruded debris generated by the nearby production lines will splash onto the maintenance personnel, causing safety accidents, which undoubtedly reduces the efficiency of pultrusion production.

DETAILED DESCRIPTION

[0035] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0036] like Figure 2-4 The figure shows a schematic diagram of the structure of the composite frame multi-mode pultrusion structure of the utility model, which includes a first drive assembly, a second drive assembly, a molding assembly and a traction assembly. The first drive assembly is arranged relatively, the second drive assembly is mounted above the first drive assembly, and the molding assembly is fixed on the first drive assembly and the second drive assembly, which saves floor space and is more convenient for repairing the extrusion die. The traction assembly is used to traction the composite frame formed by the molding assembly, which is convenient for extrusion of the product.

[0037] like Figure 5 , 6 As shown, the first driving assembly includes a slide rail 1, a slider 2 and a first support plate 3. Figure 4 As shown, the slide rail 1 is fixed on the molding machine by screw fastening, the slider 2 is slidably installed on the slide rail 1, and the first support plate 3 is fixed on the slider 2. When the power unit drives the first support plate 3 to move, it will drive the slider 2 to move synchronously along the slide rail 1, thereby increasing the stability of the movement of the first support plate 3 (the power unit can use a commercially available moving cylinder, the cylinder body of the moving cylinder is fixed on the molding machine, and the guide rod of the moving cylinder is connected to the first support plate 3 to drive the first support plate 3 to move. The moving cylinder is not shown in the figure).

[0038] like Figure 7 , which is a schematic diagram of the structure of the slider 2, the slider 2 includes a slider body 201, a first slide rail groove 202, a second slide rail groove 203, a ball groove 204, a ball bearing 205 and an anti-slip plate 206. The first slide rail groove 202 and the second slide rail groove 203 are provided on the slider body 201 and are connected to each other. The first slide rail groove 202 and the second slide rail groove 203 have the same length, and the width of the first slide rail groove 202 is smaller than the width of the second slide rail groove 203. Therefore, an inwardly protruding shoulder is formed at the top of the second slide rail groove 203. After the slide rail 1 and the slider 2 are assembled, the shoulder is used to clamp the slide rail 1 to prevent the slider 2 from slipping off the slide rail 1.

[0039] The ball grooves 204 are provided at the four corners of the second rail groove 203 along the length direction of the slider body 201. The balls 205 are arranged in the ball grooves 204. The balls 205 can roll in the ball grooves 204 but will not fall out from the two sides of the ball grooves 204. The anti-drop plates 206 are fixed on the two sides of the slider body 201 to block the two sides of the slider body 201 and prevent the balls 205 from rolling out from the two sides of the ball grooves 204.

[0040] The slide rail 1 comprises a first slide rail body 101 , a second slide rail body 102 and an avoidance arc 103 . The second slide rail body 102 is integrally connected to the top of the first slide rail body 101 , and the two have the same length.

[0041] The first slide rail body 101 cooperates with the first slide rail groove 202, and the second slide rail body 102 cooperates with the second slide rail groove 203. By relying on the plug-in cooperation between the first slide rail body 101 and the first slide rail groove 202, the second slide rail body 102 and the second slide rail groove 203, the slider 2 slides to avoid falling off the slide rail 1.

[0042] The avoidance arcs 103 are arranged at the four corners of the second slide rail body 102 and matched with the ball grooves 204 on the slider body 201, and the balls 205 are clamped between the ball grooves 204 and the avoidance arcs 103. When the moving cylinder drives the slider 2 to move, the balls 205 will rotate in the ball grooves 204, thereby improving the stability of the movement of the slider 2 and preventing the slider 2 from shaking on the slide rail 1.

[0043] The second drive assembly is mounted above the first drive assembly, and includes a ball screw 4, a lifting plate 5, a slide plate 6, a slide 7, a rack 8, a gear 9, a bearing seat 10, a flip shaft 11, an oil pressure buffer 12, and a second support plate 13. The ball screw 4 is vertically arranged and rotatably mounted on the molding machine. A driving motor is arranged below the molding machine to drive the ball screw 4 to rotate, thereby driving the nut on the ball screw 4 to perform a linear lifting motion (the driving motor is not shown in the figure).

[0044] The lifting plate 5 is fixed on the nut of the ball screw 4, and the ball screw 4 drives the lifting plate 5 to perform lifting motion (there are at least four ball screws 4, which are distributed at the four corners of the lifting plate 5 to improve the stability of the lifting motion of the lifting plate 5).

[0045] There are two bearing seats 10, which are fixed at intervals on the top of the lifting plate 5. The flip shaft 11 is installed in the bearing seat 10 through a bearing. The bearing is used to support the internal flip shaft 11 to ensure the stability of the rotation of the flip shaft 11. The second support plate 13 is fixed on the flip shaft 11. When the flip shaft 11 rotates, it drives the second support plate 13 to flip (that is, the molding component on the second support plate 13 is flipped from the processing area to the outside, which does not affect the normal use of other molding components, is convenient for maintenance, and has a higher safety factor).

[0046] The gear 9 is fixed to one end of the flip shaft 11 by a flat key. A pushing cylinder is fixed to the top of the lifting plate 5. The pushing cylinder is connected to the rack 8. The rack 8 is meshed with the gear 9. The rack 8 is pushed by the pushing cylinder to move, thereby driving the gear 9 and the flip shaft 11 to rotate, and flipping the forming assembly on the second support plate 13 from the processing area to the outside (the pushing cylinder is not shown in the figure).

[0047] The slide plate 6 is fixed to the top of the lifting plate 5 by screw fastening, and the slide groove 7 is opened on the top of the slide plate 6. The rack 8 is clamped in the slide groove 7, and the cylinder pushes the rack 8 to move, and the moving rack 8 is limited by the slide groove 7 to avoid incomplete meshing of the rack 8 and the gear 9.

[0048] By providing the meshing gear 9 and the rack 8, the flip angle of the flip axis 11 can be accurately controlled, so that the molding assembly on the second support plate 13 can be flipped to a suitable area outside for easy maintenance.

[0049] The hydraulic buffer 12 is fixed on the top of the lifting plate 5. When the molding assembly on the second support plate 13 is flipped from the outside to the processing area, the second support plate 13 is pressed on the hydraulic buffer 12 to reduce vibration and noise. At the same time, the second support plate 13 is placed on the molding frame on the top of the molding machine, and the molding frame is used to support the molding assembly on the second support plate 13.

[0050] There are four groups of molding components, which are fixed on the first support plate 3 and the second support plate 13 respectively, for extrusion molding. Each group of molding components includes a holder 14 and an extrusion die arranged opposite to each other. The extrusion die is fixed in the holder 14, and different extrusion dies can be replaced according to the actual extruded shape.

[0051] like Figure 8 , 9 As shown, the retainer 14 includes a bottom hoop 141, a top hoop 142, a lower pressing groove 143, an upper pressing groove 144, a lower sealing groove 145, an upper sealing groove 146, a lower locking plate 147, an upper locking plate 148, an inclined surface 149 and a locking hole 150. The bottom hoop 141 is fixed on the first support plate 3, the top hoop 142 is fixed on the top of the bottom hoop 141, and the extrusion mold is clamped and fixed by the bottom hoop 141 and the top hoop 142 to prevent the extrusion mold from shaking during extrusion molding.

[0052] The lower pressing groove 143 is provided on one side of the bottom hoop 141 close to the top hoop 142, and the upper pressing groove 144 is provided on one side of the top hoop 142 close to the bottom hoop 141. The cross-sections of the lower pressing groove 143 and the upper pressing groove 144 are both semicircular. When the top hoop 142 is fixed on the bottom hoop 141, the extrusion die is clamped in the circular groove formed by the lower pressing groove 143 and the upper pressing groove 144.

[0053] The lower sealing groove 145 is provided at the top of the bottom hoop 141 and is coaxially arranged with the lower pressure groove 143. The upper sealing groove 146 is provided at the bottom of the top hoop 142 and is coaxially arranged with the upper pressure groove 144. When the extrusion die is actually installed, the sealing ring is sleeved on the extrusion die. After the extrusion die is placed in the lower pressure groove 143, the top hoop 142 is fixed on the bottom hoop 141 to complete the fixation of the extrusion die. At this time, the sealing ring is in the lower sealing groove 145 and the upper sealing groove 146. During the locking process of the top hoop 142 and the bottom hoop 141, the sealing ring inside will be continuously squeezed. Relying on the elastic deformation of the sealing ring, it is ensured that the top hoop 142, the bottom hoop 141 and the extrusion die are fixed more firmly, and the extrusion die is prevented from loosening, which affects the effect after extrusion molding.

[0054] The lower locking plate 147 is integrally connected to both sides of the bottom hoop 141, and the upper locking plate 148 is integrally connected to both sides of the top hoop 142. The locking hole 150 vertically penetrates the lower locking plate 147 and the upper locking plate 148. When actually fixing, the fastening bolt is passed through the locking hole 150, and the other end is supplemented with a fastening nut to complete the fixation of the bottom hoop 141 and the top hoop 142. Due to the detachability of the fastening bolt and the fastening nut, the extrusion die matching with it can be replaced according to the different actual extrusion molding shapes.

[0055] like Figure 8 , 9As shown, the inclined surface 149 is arranged on the opposite side of the upper locking plate 148 and the lower locking plate 147 and is inclined. By setting the inclined surface 149, when the tightening bolts and the tightening nuts are screwed, the contact part between the top hoop 142 and the bottom hoop 141 is tighter, ensuring that the top hoop 142, the bottom hoop 141 and the extrusion die are fixed more firmly, avoiding the extrusion die from loosening and affecting the effect after extrusion molding.

[0056] like Figure 3 As shown, there are four groups of molding components, two of which are located in the lower layer (i.e., close to the molding machine, for the convenience of distinction, the molding components close to the molding machine are defined as the lower layer molding components). The other two groups are located in the upper layer (i.e., away from the molding machine, for the convenience of distinction, the molding components away from the molding machine are defined as the upper layer molding components).

[0057] A first driving assembly is arranged between the lower molding assembly and the molding machine, and the lower molding assembly is driven to move by the first driving assembly. When the lower molding assembly fails and needs maintenance, the first driving assembly drives the lower molding assembly out of the working area, which is convenient for maintenance and has a higher safety factor.

[0058] A second driving assembly is provided between the upper molding assembly and the molding machine, which drives the upper molding assembly to flip from the processing area to the outside and descend to the vicinity of the molding machine, thereby avoiding the need for maintenance personnel to work at heights, facilitating maintenance, and increasing the safety factor.

[0059] like Figure 3 As shown, the forming components are arranged in two layers, the upper and lower layers, which saves floor space, and the vertical projection of the upper forming component falls on the inner side of the lower forming component. During extrusion molding, the debris of the upper forming component will not fall on the lower forming component, which will not affect the extrusion molding effect. When one of the forming components fails and needs to be repaired, the forming component is directly transferred from the processing area to the external safe maintenance area, and the remaining forming components do not need to be shut down, which improves the efficiency of pultrusion molding.

[0060] like Figure 3 As shown, the upper and lower layers of molding components are distributed in the shape of an isosceles trapezoid. In actual production applications, the upper and lower layers of molding components can also be distributed in the shape of a rectangle (that is, the projection of the upper layer molding component in the vertical direction falls on the lower layer molding component). It is sufficient to set corresponding shielding objects (such as shielding plates) on the lower layer molding components to prevent the upper layer molding debris from falling.

[0061] At the same time, the molding components can be arranged side by side to reduce the distance between two adjacent molding components as much as possible to save floor space. A barrier net or barrier plate needs to be installed between two adjacent molding components.

[0062] The traction component is arranged on one side of the molding component, and is used to pull the composite material frame formed by the molding component to avoid mold blocking or incomplete product curing. Fig.10 , 11 As shown, the traction assembly includes a traction frame 15, a support frame 16, a traction mechanism and a tensioning mechanism. There is a group of support frames 16 (i.e., two, an upper support frame and a lower support frame), the lower support frame is fixed to the top of the traction frame 15 through a profile, and the upper support frame is height-adjustably arranged above the lower support frame to traction composite frames of different heights.

[0063] The support column 17 is vertically fixed to the top of the traction frame 15, and the top plate 18 is fixed to the top of the support column 17 by screw fastening. The adjustment plate 20 is fixed to the top of the upper support frame, and the cylinder body of the adjustment cylinder 19 is fixed to the top plate 18. The piston rod of the adjustment cylinder 19 passes through the top plate 18 and is connected to the adjustment plate 20 of the upper support frame. The adjustment cylinder 19 drives the adjustment plate 20 to move up and down, and then drives the upper support frame to move up and down, so as to change the distance between the upper support frame and the lower support frame, thereby pulling composite frames of different heights and improving versatility.

[0064] The guide column 21 is vertically fixed on the top of the traction frame 15 and is parallel to the support column 17. The guide sleeve 22 is sleeved on the guide column 21. The upper support frame is fixed to the guide sleeve 22. When the adjusting cylinder 19 drives the upper support frame to move up and down, it is guided by the guide sleeve 22 and the guide column 21 to avoid misalignment between the upper support frame and the lower support frame.

[0065] The traction mechanism is arranged on the inner side of the support frame 16, and the composite material frame formed by the molding assembly is pulled by the traction mechanism arranged above and below to avoid mold blocking or incomplete product solidification. The traction mechanism includes a driving wheel 23, a driven wheel 24, a traction chain 25, a drive motor 26, a support plate 27, a lug 28, a connecting plate 29 and a traction part 30. The driving wheel 23 and the driven wheel 24 are rotatably mounted on both sides of the support frame 16, respectively, and the traction chain 25 is wound around the driving wheel 23 and the driven wheel 24 (the support frame 16 is used to limit the internal traction chain 25 to prevent the traction chain 25 from being disengaged).

[0066] The housing of the driving motor 26 is fixed on one side of the support frame 16, and the driving shaft of the driving motor 26 passes through the support frame 16 and is connected to the driving wheel 23, which is used to drive the driving wheel 23 to rotate, and then drive the traction chain 25 to rotate, so as to clamp the composite material frame formed by the molding assembly and complete the traction.

[0067] The support plate 27 is fixed on the inner side of the support frame 16 and is located inside the traction chain 25. On the one hand, the support plate 27 is used to prop up the support frame 16 to prevent the support frame 16 from deforming. On the other hand, when the traction chain 25 pulls the composite material frame, it is easy to deform downward under the action of gravity. The support plate 27 can support the traction chain 25 to avoid affecting the traction effect of the composite material frame.

[0068] like Fig.12 As shown, the lugs 28 are fixed on both sides of the traction chain 25. The connecting plate 29 is fixed on the top of the lug 28, and the traction part 30 is fixed on the side of the connecting plate 29 away from the traction chain 25. When the traction chain 25 rotates, the traction part 30 is driven to rotate synchronously, thereby pulling the composite frame formed by the molding assembly to avoid mold blocking or incomplete product curing. The traction part 30 is provided to increase the contact friction with the composite frame, so as to avoid the traction chain 25 directly pulling the composite frame and causing slippage.

[0069] The tensioning mechanism is arranged on one side of the support frame 16 close to the driven wheel 24, and is used to adjust the position of the driven wheel 24 to tension the traction chain 25, so as to prevent the traction chain 25 from being deformed and elongated due to long-term traction, thereby affecting the traction efficiency of the composite frame. Fig.13 As shown, the tensioning mechanism includes a tensioning groove 31, a tensioning block 32, a slide groove 33, a locking block 34, a fixing column 35, an adjusting rod 36, an inner locking nut 37 and an outer locking nut 38. The tensioning groove 31 is horizontally opened on a side of the support frame 16 away from the driving wheel 23, and the tensioning block 32 is adjustably arranged in the tensioning groove 31.

[0070] The slide groove 33 is provided on the tension block 32, and the support frame 16 is clamped in the slide groove 33. When the tension block 32 moves, it relies on the guidance of the slide groove 33 to improve the accuracy of adjusting the position of the driven wheel 24. The driven shaft is rotatably installed between the tension blocks 32 through bearings, and the driven wheel 24 is sleeved on the driven shaft.

[0071] The locking block 34 is fixed on the tensioning block 32, the fixing column 35 is fixed on the outside of the support frame 16, and the adjusting rod 36 is fixed on the fixing column 35 and passes through the locking block 34 (the outer peripheral surface of the adjusting rod 36 is provided with an external thread, and a through hole is opened on the locking block 34, and the diameter of the through hole is larger than the outer diameter of the adjusting rod 36, so the locking block 34 can be freely adjusted along the length direction of the adjusting rod 36, thereby driving the tensioning block 32 to be freely adjusted in the tensioning groove 31).

[0072] The inner lock nut 37 and the outer lock nut 38 are respectively screwed on the adjustment rod 36, and the inner lock nut 37 and the outer lock nut 38 are respectively located on both sides of the lock block 34. After the position of the lock block 34 is adjusted, the inner lock nut 37 and the outer lock nut 38 are screwed to the two sides of the lock block 34 to lock the lock block 34.

[0073] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
