Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and in particular to a safety helmet hydraulic press protection device. Background Technology

[0002] During helmet production, the raw material of the helmet, which is made of non-woven fabric of ultra-high molecular weight polyethylene fiber or film, needs to be cut into circular sheets and stacked. The sheets are then placed on the lower mold of a hydraulic press, and the helmet material is compacted and shaped by operating the upper mold of the hydraulic press to obtain a semi-finished helmet.

[0003] However, existing technologies have some problems: because the upper and lower molds of existing hydraulic presses must be fully aligned to ensure the quality of helmet compaction, workers need to reach under the upper mold when placing helmet raw materials on the lower mold surface or removing the compacted helmet semi-finished product. Furthermore, the helmet semi-finished product may get stuck in the upper mold and need to be removed by workers. If the hydraulic press malfunctions or is misoperated at this time, the upper mold may press down, which can easily cause injury to workers and poses a safety hazard. Therefore, we propose a safety helmet hydraulic press protection device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety helmet hydraulic press protection device. By setting up a pressure plate, a translation component, and a drive component, it can prevent the helmet semi-finished product from getting stuck in the upper mold, and can move the lower mold out from directly below the upper mold to perform helmet loading and unloading operations, thereby improving safety.

[0005] The purpose of this utility model is achieved as follows: a safety helmet hydraulic press protection device includes a base, on which a hydraulic mechanism is provided, and a lower mold is provided on the top of the base. The lower mold is connected to the base through a translation component, which can move the lower mold to the front side of the top of the base. Pressure plates are provided on both sides of the lower mold, and the pressure plates are connected to the lower mold through a drive component, which enables the pressure plates to press and fix the helmet material.

[0006] Optionally, the translation component includes a servo motor, which is fixedly mounted on a base. A square groove is provided on the top of the base, and a sliding plate is fixedly mounted on the bottom of the lower mold. The sliding plate is slidably connected inside the square groove. The output shaft of the servo motor is connected to a threaded rod through a coupling, and the sliding plate is threaded onto the outer surface of the threaded rod.

[0007] Optionally, the drive assembly includes a brake motor, which is fixedly mounted on the lower mold. The output shaft of the brake motor is connected to a lead screw via a coupling. A crossbar is threaded onto the outer surface of the lead screw. Both ends of the crossbar are fixedly connected to connecting rods. Both sides of the lower mold are rotatably connected to round shafts. The pressure plate is fixedly mounted on the round shafts. The round shafts and connecting rods are connected via a rotating assembly.

[0008] Optionally, the rotating assembly includes a slider, which is fixedly mounted on a connecting rod, and an arc-shaped groove is formed on the circular shaft, with the slider and the arc-shaped groove being slidably connected.

[0009] Optionally, two guide rods are fixedly installed on the side of the lower mold near the crossbar, and the other ends of the two guide rods pass through the crossbar.

[0010] Optionally, the pressure plate is square in shape, and the surface of the pressure plate is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting up a pressure plate, a translation component, and a drive component, allows the operator to move the lower mold to the front of the top of the base using the translation component. The helmet material is then placed on the lower mold, and the pressure plate is rotated by the drive component to press the edge of the helmet material firmly against the surface of the lower mold. The lower mold is then moved back to its original position using the translation component, allowing for hydraulic operation. The helmet material, after being compacted, is limited by the pressure plate and will not get stuck in the upper mold. When handling the helmet material, the operator's hands will not be directly under the upper mold, thus preventing injury from hydraulic press malfunctions and providing good protection for the operator.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 6 As shown in the figure, the present invention provides a safety helmet hydraulic press protection device, including a base 1, a hydraulic mechanism on the base 1, a lower mold 2 on the top of the base 1, the lower mold 2 and the base 1 being connected by a translation component, the translation component being able to move the lower mold 2 to the front side of the top of the base 1, pressure plates 3 being provided on both sides of the lower mold 2, the pressure plates 3 being connected to the lower mold 2 by a drive component, the drive component being able to make the pressure plates 3 press and fix the helmet material.

[0022] The hydraulic mechanism is a mature existing technology, including hydraulic cylinders, upper molds, etc., which will not be described in detail here. When the staff picks up and puts down the helmet material, they can move the lower mold 2 to the front of the top of the base 1 through the translation component, thereby avoiding the upper mold of the hydraulic mechanism from falling down unexpectedly and causing injury to the staff. The drive component can press the helmet material through the pressure plate 3 to avoid the situation where it gets stuck in the upper mold and requires the staff to remove it, which increases the operational danger.

[0023] Furthermore, the translation component includes a servo motor 4, which is fixedly mounted on the base 1. A square groove 5 is provided on the top of the base 1, and a slide plate 6 is fixedly mounted on the bottom of the lower mold 2. The slide plate 6 is slidably connected inside the square groove 5. The output shaft of the servo motor 4 is connected to a threaded rod 7 through a coupling, and the slide plate 6 is threadedly sleeved on the outer surface of the threaded rod 7.

[0024] By activating the servo motor 4, the threaded rod 7 can rotate, which in turn causes the slide plate 6 to move the lower mold 2. This allows the lower mold 2 to move to the front of the top of the base 1, no longer directly below the upper mold. Therefore, when workers remove helmet materials from the lower mold 2, the upper mold will not accidentally fall and cause injury to the workers, thus protecting them and improving operational safety.

[0025] Furthermore, the drive assembly includes a brake motor 8, which is fixedly mounted on the lower mold 2. The output shaft of the brake motor 8 is connected to a lead screw 9 via a coupling. A crossbar 10 is threaded onto the outer surface of the lead screw 9. Both ends of the crossbar 10 are fixedly connected to connecting rods 11. Both sides of the lower mold 2 are rotatably connected to round shafts 12. A pressure plate 3 is fixedly mounted on the round shafts 12. The round shafts 12 and the connecting rods 11 are connected via a rotating assembly.

[0026] By activating the brake motor 8, the lead screw 9 can be rotated, which in turn causes the crossbar 10 to drive the connecting rod 11 to move. This, in turn, causes the rotating assembly to drive the round shaft 12 to rotate the pressure plate 3, thereby controlling the pressure plate 3 to press or release the helmet material.

[0027] Furthermore, the rotating assembly includes a slider 13, which is fixedly mounted on the connecting rod 11. An arc-shaped groove 14 is provided on the round shaft 12, and the slider 13 is slidably connected to the arc-shaped groove 14.

[0028] When the brake motor 8 runs and drives the lead screw 9 to rotate, causing the crossbar 10 to move closer to the pressure plate 3, the connecting rod 11 can drive the slider 13 to move. This allows the slider 13 to press against the inner wall of the arc groove 14, which in turn causes the round shaft 12 to drive the pressure plate 3 to rotate towards the center of the lower mold 2. This allows the pressure plate 3 to press and fix the edges and corners of the helmet material, preventing the helmet material from getting stuck in the upper mold after die casting, which would require workers to remove it and increase the operational danger.

[0029] Furthermore, two guide rods 15 are fixedly installed on the side of the lower mold 2 near the crossbar 10, and the other ends of the two guide rods 15 pass through the crossbar 10.

[0030] The guide rod 15 is designed to provide good guidance for the crossbar 10, which makes the movement of the crossbar 10 and the connecting rod 11 smoother.

[0031] Furthermore, the pressure plate 3 has a square shape and its surface is provided with anti-slip texture.

[0032] The anti-slip texture design on the surface of the pressure plate 3 makes it more stable when pressing the helmet material.

[0033] Working principle and usage process of this utility model: First, the operator starts the servo motor 4, causing the threaded rod 7 to rotate. This causes the slide plate 6 to move the lower mold 2 to the front of the top of the base 1. Then, the helmet material is placed on the lower mold 2. Next, the brake motor 8 is started, causing the lead screw 9 to rotate. This allows the crossbar 10 to move the connecting rod 11 and the slider 13 forward. This, in turn, causes the round shaft 12 to rotate through the arc groove 14, allowing the pressure plate 3 to press and fix the edge of the helmet material. Then, the brake motor 8 moves the lower mold 2 back to its original position, directly below the upper mold. The hydraulic mechanism then compacts the helmet material. After compaction, the upper mold moves upward. Because the pressure plate 3 limits the helmet material, the helmet will not get stuck in the upper mold. When removing the helmet, the lower mold 2 is also moved to the front of the top of the base 1. The entire operation does not require the operator to put their hands directly under the upper mold, thus improving operational safety and providing good protection for the operator.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
