Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to an external bending and flanging device for plastic product manufacturing. Background Technology

[0002] Plastic products often require bending and flanging during production to meet specific shape and functional requirements. Traditional bending and flanging methods for plastic products are mostly done manually, which is not only inefficient but also makes it difficult to guarantee the quality of flanging. In recent years, with the development of technology, some bending devices for plastic product production have appeared on the market to replace manual labor and improve production efficiency and product quality.

[0003] Patent No. CN 221623001 U discloses an external bending and flanging device for producing plastic products. By setting a limiting device, the limiting device can assist in limiting the plastic sheet on the flat plate, reducing the shaking or tilting of the plastic sheet on the side away from the heating plate during the bending process, and improving the stability of the plastic sheet during the bending and flanging process.

[0004] However, during use, the heating clamps heat and bend the plastic sheet, but the plastic sheet is not cooled after bending. This may cause deformation when the plastic sheet is removed, affecting the bending effect. Furthermore, removing the bent sheet is more troublesome, requiring manual removal of the fixing structure, which affects the efficiency of subsequent processing. Utility Model Content

[0005] The purpose of this utility model is to provide an external bending and flanging device for the production of plastic products, which solves the problems mentioned in the background art, such as the need for cooling the plastic sheet after bending, which may cause deformation when removing the plastic sheet, affecting the bending effect, and the inconvenience of removing the sheet after bending, which requires manual removal of the fixing structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an external bending and flanging device for producing plastic products, comprising a workbench, a bending table, and a center frame. The bending table is rotatably connected to the side wall edge of the workbench. An adjustment groove is formed on the surface of the bending table. An adjustment block is slidably connected to the inner side of the adjustment groove. A bonding plate is fixedly connected to the top of the adjustment block. A side plate parallel to the adjustment groove is fixedly connected to the top edge of the bending table. A fixing frame is fixedly connected to the side wall of the bending table. A second electric actuator is fixedly connected to the top of the fixing frame. The telescopic end of the electric actuator passes through the fixed frame and is fixedly connected to the clamping plate; a central frame is fixedly connected to the side wall of the workbench on the same side as the fixed frame; a water suction pipe and an air suction pipe are fixedly connected to the left and right side walls of the central frame, respectively; and several water spray nozzles and air outlets are evenly opened on the bottom surface of the water suction pipe and the air suction pipe, respectively; a discharge trough is opened on the surface of the workbench on one side of the central frame; a threaded rod is rotatably connected to the inner side of the discharge trough; a discharge block passes through the surface of the threaded rod and is threadedly connected to the discharge block; and a servo motor is fixedly connected to the outer side wall of the workbench at the horizontal position of the threaded rod.

[0007] In this technical solution, the water pump is connected to an external water pump, which is connected to an external water source. Water can be pumped into the water pump and sprayed towards the heating position through the nozzles. The exhaust pipe is connected to an exhaust fan, and its outlet blows air towards the heating position below. Combined with the water spray, this improves cooling efficiency, accelerates the cooling and fixing of the plastic sheet, avoids secondary deformation during the unloading process, and improves processing efficiency. After bending and cooling, the second electric push rod retracts, causing the clamping plate to disengage from the plastic sheet. At this time, the servo motor starts, driving the threaded rod to rotate, causing the discharge block to move laterally along the discharge chute, thus pushing the plastic sheet out laterally. The unloading process is convenient, eliminating the need for manual release and handling, thus improving unloading efficiency.

[0008] Preferably, the bonding plate is perpendicular to the side plate, and the clamping plate is parallel to the surface of the bending table.

[0009] Preferably, a third electric actuator is fixedly connected to the top of the central frame, and the telescopic end of the third electric actuator passes through the central frame and is fixedly connected to the heating pressure plate.

[0010] Preferably, the top surface of the bending table on one side of the adjusting groove is provided with scale lines.

[0011] Preferably, a base plate is fixedly connected to the bottom end of the side wall of the workbench support directly below the bending table, and a No. 1 electric actuator is rotatably connected between the top end of the base plate and the bottom end of the bending table through a hinge seat.

[0012] Preferably, connecting frames are welded to the far end of the central frame and the side wall of the workbench directly below it, and absorbent cotton is pasted on the opposite side of the upper and lower connecting frames.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses water suction pipes and air suction pipes on both sides of the central frame to cool the heating position. The water suction pipes are connected to an external water pump, which is connected to an external water source. Therefore, water can be pumped into the water suction pipes and sprayed onto the heating position through the spray nozzles. The air suction pipes are connected to an exhaust fan, and the air outlets of the exhaust pipes blow air onto the heating position below. Combined with the water spray from the spray nozzles, the cooling efficiency is improved, the plastic sheet is cooled and fixed more quickly, secondary deformation during the unloading process is avoided, and the processing efficiency is improved.

[0015] 2. This utility model facilitates material discharge through a second electric actuator, a clamping plate, a discharge chute, and a discharge block. After bending and cooling, the second electric actuator retracts, causing the clamping plate to disengage from the plastic sheet. At this time, the servo motor starts and drives the threaded rod to rotate, causing the discharge block to move laterally along the discharge chute, thereby pushing the plastic sheet out laterally. The discharge process is relatively convenient, eliminating the need for manual release and handling, thus improving the efficiency of material discharge. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] An external bending and flanging device for manufacturing plastic products, see [link / reference]. Figures 1 to 3 The system includes a workbench 1, a bending table 2, and a center frame 11. The bending table 2 is rotatably connected to the side wall edge of the workbench 1. An adjustment groove 8 is formed on the surface of the bending table 2. An adjustment block 9 is slidably connected to the inner side of the adjustment groove 8. A bonding plate 901 is fixedly connected to the top of the adjustment block 9. A side plate 5 parallel to the adjustment groove 8 is fixedly connected to the top edge of the bending table 2. A fixing frame 6 is fixedly connected to the side wall of the bending table 2. A second electric actuator 7 is fixedly connected to the top of the fixing frame 6. The telescopic end of the second electric actuator 7 passes through the fixing frame 6 and is fixedly connected to the clamping plate 701. A center frame 11 is fixedly connected to the side wall of the workbench 1 on the same side as the fixing frame 6. The left and right side walls of the core frame 11 are respectively fixedly connected to a water suction pipe 12 and an exhaust pipe 13. The bottom surfaces of the water suction pipe 12 and the exhaust pipe 13 are evenly provided with a number of water spray nozzles 121 and air outlets 131. The water suction pipe 12 is connected to an external water pump, which is connected to an external water source to pump water into the water suction pipe 12 and spray it towards the heating position along the water spray nozzles 121. The exhaust pipe 13 is connected to an exhaust fan, and the air outlet 131 of the exhaust pipe 13 blows air towards the heating position below. Combined with the water spray from the water spray nozzles 121, the cooling efficiency is improved, the plastic sheet is cooled and fixed more quickly, and secondary deformation during the discharge process is avoided.

[0023] Meanwhile, a discharge groove 16 is provided on the surface of the workbench 1 on one side of the central frame 11. A threaded rod 17 is rotatably connected to the inner side of the discharge groove 16. A discharge block 18 passes through the surface of the threaded rod 17 and is threadedly connected to the discharge block 18. A servo motor 171 is fixedly connected to the outer wall of the workbench 1 at the horizontal position of the threaded rod 17. When the second electric push rod 7 retracts, it drives the clamping plate 701 to disengage from the plastic sheet. At this time, the servo motor 171 starts and drives the threaded rod 17 to rotate, so that the discharge block 18 moves laterally along the discharge groove 16, thereby pushing the plastic sheet out laterally. The discharge process is relatively convenient and does not require manual release of fixation and handling.

[0024] Specifically, such as Figure 1 As shown, the bonding plate 901 is perpendicular to the side plate 5. Therefore, the bonding plate 901 and the side plate 5 form a right-angle area to limit and fix the plastic plate. This not only straightens the plastic plate but also quickly completes the positioning and fixing. In addition, the clamping plate 701 is parallel to the surface of the bending table 2, so it can perfectly fit the surface of the plastic plate to clamp the plastic plate.

[0025] It is worth noting that, such as Figure 3As shown, a No. 3 electric actuator 14 is fixedly connected to the top of the central frame 11. The telescopic end of the No. 3 electric actuator 14 passes through the central frame 11 and is fixedly connected to the heating plate 15. When the No. 3 electric actuator 14 is activated, it drives the heating plate 15 to descend and heat the plastic plate. The heating plate 15 is equipped with heating components such as electric heating tubes inside. It can generate heat after being powered on, thus facilitating the heating of the plastic plate. Moreover, the technology is relatively mature and does not require protection, so it will not be described in detail.

[0026] It is worth noting that, such as Figure 1 As shown, the top surface of the bending table 2 on one side of the adjusting groove 8 is provided with a scale line 10. The scale line 10 can easily change the position of the adjusting block 9, thereby adapting to the bending processing of the plastic sheet at different positions. The top edge of the adjusting block 9 is threaded with a bolt. The bolt passes through the adjusting block 9 and contacts the surface of the bending table 2. After the bolt is tightened, the adjusting block 9 can be squeezed into the current position and kept stable.

[0027] It is worth noting that, such as Figure 3 As shown, a base plate 3 is fixedly connected to the bottom end of the side wall of the workbench 1 directly below the bending table 2. A first electric push rod 4 is rotatably connected between the top of the base plate 3 and the bottom of the bending table 2 through a hinge seat. When the first electric push rod 4 is activated, the bending table 2 will be raised, thereby bending the plastic sheet on the surface of the bending table 2.

[0028] It is worth noting that, such as Figure 1 As shown, connecting frames 19 are welded to the far end of the center frame 11 and the side wall of the workbench 1 directly below it. Water-absorbing cotton 20 is pasted on the surface of the opposite side of the two connecting frames 19. When the discharge block 18 pushes the plastic plate to discharge, the plastic plate will pass between the two connecting frames 19. At this time, the water-absorbing cotton 20 will simply absorb the water on the surface of the plastic plate, and the remaining water that has not been absorbed will evaporate more easily.

[0029] In actual use, the plastic sheet is placed on the surface of the workbench 1 and bending table 2. The adjusting block 9 is slid according to the bending position. The bonding plate 901 blocks the plastic sheet, and the bonding plate 901 and the side plate 5 form a right-angle area to jointly constrain the plastic sheet. Then, the second electric actuator 7 is activated, causing the clamping plate 701 to descend, thus clamping the plastic sheet. Next, the third electric actuator 14 is activated, causing the heating pressure plate 15 to descend, squeezing and heating the bending area of ​​the plastic sheet. After heating to a certain degree, bending can begin. The first electric actuator 4 is activated, causing the bending table 2 to rise, thus bending the plastic sheet. After bending is complete, cooling begins. Because the water pipe 12 is connected to an external water pump, and the water pump is connected to an external water source... This allows water to be pumped into the water pipe 12 and sprayed towards the heating position through the spray nozzle 121. The exhaust pipe 13 is connected to the exhaust fan, and the air outlet 131 of the exhaust pipe 13 blows air towards the heating position below. Combined with the water spray from the spray nozzle 121, this improves the cooling efficiency, accelerates the cooling and fixing of the plastic sheet, avoids secondary deformation during the unloading process, and improves processing efficiency. After bending and cooling are completed, the second electric push rod 7 retracts, causing the clamping plate 701 to disengage from the plastic sheet. At this time, the servo motor 171 starts and drives the threaded rod 17 to rotate, causing the discharge block 18 to move laterally along the discharge groove 16, thereby pushing the plastic sheet out laterally. The unloading process is more convenient, eliminating the need for manual release and handling, thus improving the unloading efficiency.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
