Description

Technical Field

[0001] This utility model relates to the field of double-top hydraulic press technology, and more specifically, to a direction conversion device for a double-top hydraulic press. Background Technology

[0002] A hydraulic press is a machine that uses liquid as its working medium and is designed based on Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the main machine (host), the power system, and the hydraulic control system. Hydraulic presses can be classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. In addition to forging and forming, hydraulic presses can also be used for straightening, pressing, packaging, briquetting, and pressing plates.

[0003] Currently, some existing hydraulic presses, due to their integrated fixed structure, only press materials in a single direction. This means that if materials require multi-directional pressing, they must be flipped, which affects processing efficiency. Therefore, we provide a double-top hydraulic press direction conversion device. Utility Model Content

[0012] Preferably, a stop block is fixedly connected to the top of the base, and the stop block is used in conjunction with the second pressure plate.

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

[0014] Start the hydraulic cylinder, which directly drives the first pressure plate downward to press the top surface of the material. After the top surface of the material is pressed, control the hydraulic cylinder to drive the first pressure plate to reset.

[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] Please see Figures 1 to 4 A double-top hydraulic press direction conversion device includes a base 1, a bracket 2 fixedly connected to the top of the base 1, a top plate 3 fixedly connected to the outside of the bracket 2, a hydraulic cylinder 4 fixedly connected to the top of the top plate 3, a first pressure plate 5 fixedly connected to the output end of the hydraulic cylinder 4, the hydraulic cylinder 4 directly drives the first pressure plate 5 to perform top surface pressing of the material, a rack 6 fixedly connected to the top of the first pressure plate 5, a first fixed plate 7 fixedly connected to the bottom of the top plate 3, a gear 8 rotatably connected to the outside of the first fixed plate 7, the gear 8 meshing with the rack 6, the rack 6 enabling the first pressure plate 5 to drive the gear 8 to rotate, a first groove 9 is formed inside the top plate 3, a slide plate 10 is slidably connected inside the first groove 9, a slide groove 11 is formed inside the slide plate 10, a slide rod 12 is slidably connected inside the slide groove 11, the slide rod 12 is fixedly connected to the gear 8, a second fixed plate 13 is fixedly connected to the outside of the slide plate 10, and a second pressure plate 14 is fixedly connected to the outside of the second fixed plate 13, the second pressure plate 14 performs side pressing of the material.

[0022] Furthermore, the slide 11 has an arc-shaped structure. The arc-shaped structure ensures that when the first pressure plate 5 moves downward, the slide rod 12 will not squeeze the slide 11. Only when the first pressure plate 5 is reset and continues to move upward will the slide rod 12 squeeze the slide 11, thereby driving the slide plate 10 to move. The second fixed plate 13 has a U-shaped structure. The U-shaped structure can prevent the second fixed plate 13 and the first pressure plate 5 from obstructing each other when the second pressure plate 14 performs side punching on the material.

[0023] Furthermore, a second groove 15 is provided inside the base 1, and a slider 16 is slidably connected inside the second groove 15. The slider 16 is fixedly connected to the second pressure plate 14. A limit rod 17 is slidably connected inside the slider 16. The limit rod 17 is fixedly connected to the base 1. The second pressure plate 14 is limited by the slider 16 and the second groove 15, so that the second pressure plate 14 moves more smoothly. A limit rod 17 is also provided inside the slide plate 10. The limit rod 17 is fixed to the top plate 3.

[0024] Furthermore, a third groove 18 is provided inside the base 1 on both sides of the corresponding slider 16. The third groove 18 is connected to the second groove 15. A baffle 19 is slidably connected inside the third groove 18. The baffle 19 is fixedly connected to the slider 16. The baffle 19 can block the second groove 15 to prevent debris from falling into the second groove 15 and avoid obstructing the movement of the slider 16 and the second pressure plate 14.

[0025] Furthermore, the base 1 is externally fixedly connected to a control panel 20, and the hydraulic cylinder 4 is electrically connected to the control panel 20. The control panel 20 is used to control the hydraulic cylinder 4, which drives the first pressure plate 5 to move up and down, thereby pressing the material on the top surface.

[0026] Furthermore, a stop block 21 is fixedly connected to the top of the base 1. The stop block 21 works in conjunction with the second pressure plate 14. The stop block 21 is used to block the material, so that the device can perform side punching on the material through the second pressure plate 14.

[0027] The steps of using this utility model are as follows: When using this double-top hydraulic press direction conversion device, start the hydraulic cylinder 4. The hydraulic cylinder 4 directly drives the first pressure plate 5 to move downward to press the material on the top surface. At this time, when the first pressure plate 5 moves downward, although it will also drive the gear 8 to rotate through the rack 6, the sliding rod 12 on the gear 8 only slides in the arc-shaped groove 11 and does not squeeze the inner wall of the groove 11. Therefore, the slide plate 10 will not move at this time, and the corresponding second pressure plate 14 will not move either. After the material is pressed on the top surface, control the hydraulic cylinder 4 to drive the first pressure plate 5 to reset, and then control the hydraulic cylinder 4 to drive the first pressure plate 5 to continue to move upward. At this time, the gear 8 can squeeze the inner wall of the groove 11 through the sliding rod 12, thereby driving the slide plate 10 to move. The slide plate 10 drives the second pressure plate 14 to approach the material through the second fixed plate 13, and cooperates with the stop block 21 to press the material on the side. There is no need to manually flip the material, making the operation more convenient.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
