Description

Technical Field

[0001] This utility model relates to the field of automotive interior fiberglass board production technology, and in particular to a cold pressing device for automotive interior fiberglass board production. Background Technology

[0002] The working principle of the cold press machine for automotive interior fiberglass panels is to use pressure (rather than heat) to fully compress the internal glass fiber reinforcement material (such as fiberglass felt or fiberglass cloth) and resin, so that the two can be tightly bonded, thereby improving the strength of the fiberglass panel itself.

[0003] A search revealed that patent application number 202123145954.6 discloses a cold pressing device for producing fiberglass panels for automotive interiors, which includes a cold press. The cold press has a pressure plate inside, and the lower end of the pressure plate is provided with a transverse positioning plate and a longitudinal positioning plate.

[0004] The aforementioned patent can prevent the fiberglass board from shifting during the pressing process by limiting the position of each positioning plate. However, the positioning position of the positioning plate is not easy to adjust flexibly, and it cannot better adapt to the positioning requirements of fiberglass boards of different lengths. Furthermore, the pressing plate cannot apply pressure evenly on the entire pressing plane of the fiberglass board, resulting in uneven material density inside the fiberglass board. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cold pressing device for the production of automotive interior fiberglass panels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cold pressing device for producing automotive interior fiberglass panels includes an L-shaped limiting baffle welded to the outer wall of the top of a workbench. A fiberglass panel body is placed on the workbench. An adjustable positioning mechanism and a servo-moving hydraulic mechanism are sequentially provided on the L-shaped limiting baffle.

[0008] The servo-moving hydraulic mechanism includes a hydraulic component, a linear guide rail fixedly connected to the outer wall of the L-shaped limit baffle, a servo motor fixedly connected to the L-shaped limit baffle via a motor fixing plate, a transverse lead screw, an adjusting seat threadedly connected to the transverse lead screw and slidably connected to the linear guide rail, and an L-shaped connecting frame fixedly connected to the top outer wall of the adjusting seat.

[0009] The hydraulic assembly includes a top seat fixedly connected to the side wall of the L-shaped connecting frame, a hydraulic cylinder fixedly installed on the outer wall of the top center of the top seat, and a pressing plate fixedly connected to the telescopic end of the hydraulic cylinder.

[0010] Preferably, the linear guide rail has two bearing seats symmetrically fixed on its side wall, the transverse lead screw is rotatably mounted on the two bearing seats, and the servo motor is coaxially fixedly connected to one end of the transverse lead screw through a coupling.

[0011] With the above-mentioned structure, the output shaft of the servo motor can control the stable rotation of the horizontal lead screw, thereby ensuring the stability of the hydraulic components during horizontal movement.

[0012] Preferably, each of the four outer corners of the top seat is fixedly connected with a telescopic guide rod, the telescopic ends of the four telescopic guide rods and the telescopic ends of the hydraulic cylinders all penetrate the top seat, and the telescopic ends of the four telescopic guide rods are all fixed to the top outer wall of the pressing plate.

[0013] With the above structure, the telescopic guiding effect of the four telescopic guide rods can ensure the stability of the pressing action of the pressing plate, thereby ensuring the uniformity of the pressure applied by the pressing plate.

[0014] Preferably, the adjustable positioning mechanism includes a groove formed on the inner side wall of the L-shaped limiting baffle, an adjusting screw rotatably installed in the groove, and a positioning plate threadedly connected to the adjusting screw, wherein the outer wall of the positioning plate is slidably connected to the inner wall of the groove.

[0015] The above structure allows for flexible adjustment of the positioning plate's position, making it easier to better adapt to the positioning needs of fiberglass board bodies of different lengths.

[0016] Preferably, a threaded locking post is coaxially welded to the outer wall of one end of the adjusting screw, and a locking nut is threadedly connected to the threaded locking post, and the locking nut forms a tight fit with the outer wall of the L-shaped limiting baffle.

[0018] Preferably, a rotating cap is fixedly connected to the outer wall of one end of the threaded locking post.

[0019] With the above structure, the adjustment screw welded on the threaded locking post can be easily rotated manually by installing a rotating cap.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. In the cold pressing process, the telescopic guiding effect of the four telescopic guide rods can ensure the stability of the pressing plate's downward action, thereby ensuring the uniformity of the pressure applied to the pressing plate. Furthermore, the servo-driven hydraulic mechanism facilitates the orderly axial movement of the entire hydraulic assembly, enabling the pressing plate to apply pressure evenly across the entire pressing surface of the fiberglass board. This helps to make the material density inside the fiberglass board more uniform and improves the strength of the fiberglass board itself.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1, referring to Figure 1-3 A cold pressing device for producing automotive interior fiberglass panels includes an L-shaped limiting baffle 2 welded to the top outer wall of a workbench 1, a fiberglass panel body 3 placed on the workbench 1, and a servo-moving hydraulic mechanism provided on the L-shaped limiting baffle 2.

[0030] Specifically, the servo-moving hydraulic mechanism includes a hydraulic component, a linear guide rail 4 fixedly connected to the outer wall of the L-shaped limit baffle 2, a servo motor 5 fixedly connected to the L-shaped limit baffle 2 via a motor fixing plate, a transverse lead screw 6, an adjusting seat 7 threadedly connected to the transverse lead screw 6 and slidably connected to the linear guide rail 4, and an L-shaped connecting frame 8 fixedly connected to the top outer wall of the adjusting seat 7.

[0031] Furthermore, the hydraulic assembly includes a top seat 9 fixedly connected to the side wall of the L-shaped connecting frame 8, a hydraulic cylinder 10 fixedly installed on the outer wall of the top center of the top of the top seat 9, and a pressing plate 11 fixedly connected to the telescopic end of the hydraulic cylinder 10.

[0032] Furthermore, two bearing seats 13 are symmetrically fixed on the side wall of the linear guide rail 4, and the transverse screw 6 is rotatably mounted on the two bearing seats 13. The servo motor 5 is coaxially fixedly connected to one end of the transverse screw 6 through a coupling. In this way, the output shaft of the servo motor 5 can control the stable rotation of the transverse screw 6, thereby ensuring the stability of the hydraulic components during horizontal movement. In order to ensure the normal operation of the hydraulic cylinder 10, the hydraulic cylinder 10 can be connected to an external oil pump through a telescopic hose.

[0033] Furthermore, telescopic guide rods 12 are fixedly connected to the outer walls of the four corners of the top seat 9. The telescopic ends of the four telescopic guide rods 12 and the telescopic ends of the hydraulic cylinder 10 all penetrate the top seat 9. The telescopic ends of the four telescopic guide rods 12 are fixed to the outer wall of the top of the pressing plate 11. Therefore, the telescopic guiding effect of the four telescopic guide rods 12 can ensure the stability of the pressing action of the pressing plate 11, thereby ensuring the uniformity of the pressure applied by the pressing plate 11.

[0034] The working principle of this embodiment is as follows: First, the servo motor 5 is pre-encoded by an external encoder according to the length of the fiberglass board body 3 to set the travel distance of the entire hydraulic assembly. At this time, the hydraulic cylinder 10 controls the pressing plate 11 to move downward continuously to compact the material inside the fiberglass board body 3. Second, the servo motor 5 drives the transverse screw 6 to rotate. Then, under the guidance of the linear guide rail 4, the adjusting seat 7, which is threadedly connected to the transverse screw 6, will drive the entire hydraulic assembly to move in an orderly manner along the axial direction. This allows the pressing plate 11 to apply pressure evenly on the pressing plane of the entire fiberglass board body 3, which is beneficial to make the material density inside the fiberglass board more uniform and to improve the strength of the fiberglass board itself.

[0035] Example 2, refer to Figure 1 and Figure 4 This embodiment is an optimization based on embodiment 1. Specifically, the L-shaped limiting baffle 2 is also provided with an adjustable positioning mechanism.

[0036] More specifically, the adjustable positioning mechanism includes a slide groove formed on the inner side wall of the L-shaped limiting baffle 2, an adjusting screw 14 rotatably installed in the slide groove, and a positioning plate 15 threadedly connected to the adjusting screw 14. The outer wall of the positioning plate 15 is slidably connected to the inner wall of the slide groove.

[0037] Furthermore, a threaded locking post 16 is coaxially welded to the outer wall of one end of the adjusting screw 14, and a locking nut 17 is threaded onto the threaded locking post 16. The locking nut 17 forms a tight fit with the outer wall of the L-shaped limit baffle 2. The locking fit between the threaded locking post 16 and the locking nut 17 helps to ensure the stability of the positioning plate 15 after it is fully positioned. A rotating cap 18 is fixedly connected to the outer wall of one end of the threaded locking post 16. The rotating cap 18 facilitates manual operation of the adjusting screw 14 welded onto the threaded locking post 16.

[0038] The working principle of this embodiment is as follows: First, loosen the butterfly locking nut 17, then rotate the threaded locking pin 16 by rotating the cap 18. The threaded locking pin 16 will then drive the adjusting screw 14 to rotate coaxially. Then, under the limit of the slide groove, the positioning plate 15, which is threadedly connected to the adjusting screw 14, will move forward to effectively position the fiberglass board body 3. After positioning, tighten the butterfly locking nut 17 to ensure the stability of the positioning plate 15 after it is fully positioned, and to prevent it from shifting during the pressing process. In this way, by flexibly adjusting the position of the positioning plate 15, it is easier to adapt to the positioning requirements of fiberglass board bodies 3 of different lengths.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
