Description

A protective device for a hydraulic press Technical Field

[0001] This utility model relates to the field of protection device technology, specifically a protection device for a hydraulic press. Background Technology

[0002] With the continuous development and upgrading of the manufacturing industry, higher requirements have been placed on the safety, reliability and automation of hydraulic presses. Advanced production processes and high-quality product production require stable and reliable equipment support. As an important part of ensuring the safe operation of hydraulic presses, the performance and quality of protection devices directly affect the smooth progress of the entire production process. During stamping, forging and other operations, the impact force generated by the rapid descent of the hydraulic press slide is very large. If the mold is not installed properly, the workpiece is placed incorrectly, or the equipment itself malfunctions, it may cause the slide movement to go out of control and generate abnormal impact force, which may not only damage the mold and equipment, but also cause damage to surrounding personnel and facilities.

[0003] When using protective devices for hydraulic presses, traditional protective devices are generally used in the form of induction and anti-touch to prevent workers from touching the machine while it is in operation. However, during stamping and other operations, if the object being stamped is misplaced or has poor explosion resistance, it can easily pose a safety threat to nearby workers, reducing the practicality and safety of the equipment. Summary of the Invention

[0004] The purpose of this utility model is to provide a protective device for hydraulic presses, in order to solve the problem that traditional protective devices mentioned in the background art are generally used in the form of induction and anti-touch to prevent workers from contacting the machine in operation. However, during stamping and other operations, if the stamped items are misplaced or have poor explosion resistance, they can easily pose a safety threat to nearby workers, reducing the practicality and safety of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for a hydraulic press, comprising a device body, a stamping pad fixedly connected to the center of the bottom surface of the device body, sliding rods fixedly connected to the top and bottom surfaces of the device body near the four corners, a hydraulic telescopic rod fixedly installed near the center of the top surface of the device body, a stamping lifting platform fixedly connected to the bottom end of the hydraulic telescopic rod, and the stamping lifting platform slidably connected to the four sliding rods, fixing blocks fixedly connected to the outer surfaces of both sides of the stamping lifting platform near the center, and a first transmission gear scale fixedly connected to the outer surfaces of the opposite sides of the two fixing blocks.

[0006] In a preferred embodiment, the inner surface walls on both sides of the main body of the device are provided with a first sliding groove at the rear edge, and the first sliding groove is slidably limited to the first transmission gear scale.

[0007] In a preferred embodiment, the inner surface walls on both sides of the main body of the device are provided with a second sliding groove at the edge near the front side, and a second transmission gear is slidably connected inside the two second sliding grooves.

[0008] In a preferred embodiment, two fixed short rods are fixedly connected to the inner surface walls of the main body of the device near the center, and gears are rotatably connected to the opposite ends of the two fixed short rods.

[0009] In a preferred embodiment, the outer surfaces of both the first and second transmission gear scales are meshed with gears.

[0010] In a preferred embodiment, a third sliding groove is provided on the bottom surface of the main body of the device near the front edge, and a protective baffle is fixedly connected between the bottoms of the two second transmission gears near the front edge, and the protective baffle is slidably disposed with the third sliding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention first activates a hydraulic telescopic rod, causing one end to extend downwards, which in turn drives a stamping lifting platform to slide downwards and stamp the items placed inside the stamping pad. The sliding rod design ensures a smoother downward sliding process. The downward sliding of the stamping lifting platform synchronously drives a first transmission gear scale to slide downwards within a first groove via a fixed block. With a fixed short rod rotatably connected to a gear, and both the first and second transmission gear scales meshing with the gear, the downward sliding of the first transmission gear scale drives the gear to rotate. This rotation of the gear, in turn, drives the second transmission gear scale to slide upwards. The simultaneous upward sliding of both second transmission gear scales causes a protective baffle to slide upwards and engage in front of the platform as it stamps downwards. This protective baffle prevents direct contact between workers and the equipment and also prevents items from being crushed and exploding, thus improving the practicality and safety of the equipment.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please refer to Figures 1-4. This utility model provides a technical solution: a protective device for a hydraulic press, including a main body 1. A stamping pad 2 is fixedly connected to the center of the bottom surface inside the main body 1. The stamping pad 2 can be used to place stamped items. Slide rods 3 are fixedly connected to the top and bottom surfaces of the main body 1 near the four corners. The slide rods 3 make the lifting and sliding of the stamping platform 5 more stable. A hydraulic telescopic rod 4 is fixedly installed near the center of the top surface inside the main body 1. The hydraulic telescopic rod 4 can control the up and down sliding of the stamping platform 5. The bottom end of the hydraulic telescopic rod 4 is fixedly connected to the stamping platform 5. The stamping lifting platform 5 is slidably connected to four sliding rods 3. When the stamping lifting platform 5 slides downward, it can drive the two fixed blocks 6 to adjust downward synchronously. At the same time, the downward pressing of the stamping lifting platform 5 can stamp the items placed on the stamping pad 2. Fixed blocks 6 are fixedly connected to the outer surfaces of both sides of the stamping lifting platform 5 near the center. When the fixed blocks 6 are adjusted downward, they can drive the first transmission gear 7 to slide downward inside the first slide groove 8. The outer surfaces of the opposite sides of the two fixed blocks 6 are fixedly connected to the first transmission gear 7. The downward sliding of the first transmission gear 7 can drive the gear 12 to rotate through the meshing action of the first transmission gear 7 and the gear 12.

[0021] Both sides of the inner surface of the device body 1 have longitudinally formed first sliding grooves 8 near the rear edge, and the first sliding grooves 8 slide and limit the movement of the first transmission gear 7. The first sliding grooves 8 make the sliding of the first transmission gear 7 more stable. Both sides of the inner surface of the device body 1 have longitudinally formed second sliding grooves 9 near the front edge, and the second sliding grooves 9 make the up-and-down sliding of the second transmission gear 10 more stable. The second transmission gear 10 is slidably connected inside both second sliding grooves 9. When the second transmission gear 10 slides upward, it can... The protective baffle 14 slides upward synchronously. Fixed short rods 11 are fixedly connected to the inner surface walls of both sides of the main body 1 near the center. Gears 12 are rotatably connected to the opposite ends of the two fixed short rods 11. The outer surfaces of the first transmission gear 7 and the second transmission gear 10 on opposite sides are meshed with the gears 12. With the first transmission gear 7 and the second transmission gear 10 meshing with the gears 12, when the first transmission gear 7 slides downward, it can drive the gears 12 to rotate. The rotation of the gears 12 drives the second transmission gear 10 to slide upward.

[0022] A third slide groove 13 is provided on the bottom surface of the main body 1 near the front edge. A protective baffle 14 is fixedly connected between the bottoms of the two second transmission gears 10 near the front edge. The protective baffle 14 is slidably set with the third slide groove 13. Through the setting of the third slide groove 13 and the protective baffle 14, the hydraulic telescopic rod 4 drives the stamping lifting platform 5 to stamp the item downwards. The protective baffle 14 slides upwards to separate the work, which can prevent the staff from direct contact with the equipment and prevent the item from being squeezed and exploding, thus improving the practicality and safety of the equipment.

[0023] Working principle: When the hydraulic press is used with the protection device, the hydraulic telescopic rod 4 is activated first, causing one end of the hydraulic telescopic rod 4 to extend downward, thereby driving the stamping lifting platform 5 to slide downward and stamp the items placed inside the stamping pad 2. The sliding rod 3 makes the downward sliding process of the stamping lifting platform 5 more stable. The downward sliding of the stamping lifting platform 5 can synchronously drive the first transmission gear 7 to slide downward inside the first slide groove 8 through the fixed block 6. The fixed short rod 11 is rotatably connected to the gear 12, and the first transmission gear 7 and the second transmission gear 10 are connected. With both gears meshing with each other, when the first transmission gear 7 slides downward, it can drive the gear 12 to rotate. The rotation of the gear 12 drives the second transmission gear 10 to slide upward. When the two second transmission gears 10 slide upward at the same time, the stamping lifting platform 5 can simultaneously drive the protective baffle 14 to slide upward and block it in front when it stamps downward. The protective baffle 14 can prevent the staff from direct contact with the equipment and can also prevent the items from being squeezed and exploding, thus improving the practicality and safety of the equipment.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
