Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic press safety devices, specifically a safety support device for a hydraulic press. Background Technology

[0002] In industrial production, hydraulic presses are commonly used for material forming and processing. However, after shutdown, due to factors such as hydraulic system leaks and aging seals, the slide block is prone to sliding down, and there is a lack of effective safety support between the upper and lower slide blocks during operation. This not only damages the mold and increases maintenance costs, but also poses a significant safety hazard to operators during equipment maintenance and other operations, as the slide block may accidentally slide down, affecting production safety and continuity.

[0003] Chinese Patent Publication No. 201720421872.4 discloses an automatic safety support device for a hydraulic press. This invention relates to a safety device applied in hydraulic presses. The safety support device is fixed to the hydraulic press platform with bolts. The device includes a control mechanism, a drive mechanism, and a sliding mechanism. The control mechanism is connected to the sliding mechanism through the drive mechanism, and the sliding mechanism reciprocates under the action of the drive mechanism. The main purpose of this invention is to provide automated safety assurance for personnel during the operation, maintenance, and debugging of hydraulic equipment. It is a time-saving, labor-saving, intelligent, and efficient safety technology measure that effectively solves the safety problems and equipment damage caused by human factors in traditional work methods.

[0004] In the existing technology, when using an automatic safety support device for a hydraulic press, under high load conditions, such as heavy hydraulic presses pressing large workpieces, the support is provided only by two support rods on both sides. This makes it impossible to flexibly increase the support area, form a stable triangular or polygonal support structure, and effectively distribute the pressure. Therefore, we have made improvements to this and proposed a safety support device for a hydraulic press. Utility Model Content

[0005] The purpose of this utility model is to address the problem that in the current use of an automatic safety support device for hydraulic presses, when facing high-load conditions, such as heavy hydraulic presses pressing large workpieces, the support is provided only by two support rods on both sides, which makes it impossible to flexibly increase the support area, form a stable triangular or polygonal support structure, and effectively distribute the pressure.

[0007] A safety support device for a hydraulic press includes auxiliary support side plates and sliding plates distributed on opposite sides of the main support block. These are connected to the main support block via rotating rods and mounting plates. When the load on the hydraulic press increases, sensors detect pressure changes, and a controller causes the auxiliary support side plates and sliding plates to expand outward and automatically adjust their angles.

[0033] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -6. A safety support device for a hydraulic press includes a hydraulic press body base 1. Multiple support plates 2 are provided on the top of the hydraulic press body base 1. The multiple support plates 2 are inserted into the interior of the hydraulic press body base 1 and slidably connected thereto. A first electric telescopic rod 3 is embedded in the top of each of the multiple support plates 2. Support blocks 4 are fixedly installed at the output ends of each of the multiple first electric telescopic rods 3. Side plates 5 are provided on the corresponding sides of each of the multiple support blocks 4. A sliding plate 22 is provided above each of the multiple side plates 5. A rotating rod 6 is fixedly installed on one side of each of the multiple side plates 5. Mounting plates 7 are provided on the outer sides of each of the multiple support blocks 4 and on the corresponding sides of each of the multiple rotating rods 6. The mounting plates 7 are fixedly connected to the support blocks 4. The rotating rods 6 are inserted into the interior of the mounting plates 7 and rotatably connected thereto. Auxiliary structures are provided on each of the multiple side plates 5.

[0034] In this embodiment of the utility model, the support block 4 is moved longitudinally by the synchronous operation of multiple first electric telescopic rods 3, and the sliding plates 22 on both sides of the multiple support blocks 4 are moved laterally by the rotating side plates 5 on both sides of the multiple support blocks 4 and the auxiliary structure.

[0035] In this embodiment of the utility model, the height of the support block 4 is adjusted by the first electric telescopic rod 3, which makes it easy for the device to automatically adjust the height of the support device according to different mold heights and processing requirements, so that the support device is always kept in the optimal support position, effectively improving the versatility and work efficiency of the equipment.

[0036] Worm gears 8 are fixedly installed on the outer side of multiple rotating rods 6, and worms 9 are meshed on the outer side of multiple worm gears 8. Multiple worm gears 8 and worms 9 are rotatably connected to support block 4. A connecting rod 10 is fixedly installed between two adjacent worms 9, and the connecting rod 10 is rotatably connected to support block 4.

[0037] Gears 11 are fixedly installed on the outer side of multiple connecting rods 10. The gears 11 are rotatably connected to the support block 4. Racks 12 are meshed on the outer side of multiple gears 11. The racks 12 are slidably connected to the support block 4. Second electric telescopic rods 13 are fixedly installed inside multiple support blocks 4. The output end of the second electric telescopic rods 13 is fixedly connected to the racks 12.

[0038] The auxiliary structure includes a third electric telescopic rod 19, which is inserted into the side plate 5 and fixedly connected thereto. Two auxiliary blocks 20 are provided on the side of the side plate 5 and the slide plate 22 that are close to each other. A rotating plate is rotatably connected between two adjacent auxiliary blocks 20 through a rotating shaft. The output end of the third electric telescopic rod 19 is fixedly connected to one of the auxiliary blocks 20, and the other auxiliary block 20 is fixedly connected to the slide plate 22. A limit rod 23 is provided inside the slide plate 22. The limit rod 23 passes through the slide plate 22 and is slidably connected thereto. The limit rod 23 is fixedly connected to the support block 4.

[0039] In this embodiment of the utility model, the synchronous operation of multiple second electric telescopic rods 13 causes the rack 12 to move laterally and mesh with the gear 11, driving the worm gears 9 on both sides of the connecting rod 10 to operate synchronously in the same direction. The worm gears 9 installed on both sides of the connecting rod 10 are symmetrically arranged, realizing the opposite rotation of two adjacent worm wheels 8, causing the corresponding side plates 5 on both sides of the support block 4 to rotate towards or repel each other. Through the action of the set auxiliary structure, the operation of the third electric telescopic rod 19 pushes one of the auxiliary blocks 20, and through the cooperation of the set rotating plate and the other auxiliary block 20, the opposite or repulsive movement of two adjacent sliding plates 22 is realized.

[0040] In this embodiment of the invention, the device consists of an adaptive multi-level linkage support structure composed of multiple main support blocks 4, multiple auxiliary support side plates 5, and a sliding plate 22. The main support blocks 4 are made of high-strength alloy steel, and a first electric telescopic rod 3 is installed at the bottom of the main support blocks 4 to automatically adjust the height according to the working state and load of the hydraulic press. The auxiliary support side plates 5 and the sliding plate 22 are distributed on the corresponding sides of the main support blocks 4 and are connected to the main support blocks 4 through a rotating rod 6 and a mounting plate 7. When the load of the hydraulic press increases, the sensor detects the pressure change and the controller 21 causes the auxiliary support side plates 5 and the sliding plate 22 to unfold outward and automatically adjust the angle to increase the support area and enhance stability.

[0041] Example 2: Please refer to the appendix of the instruction manual. Figure 5In a preferred embodiment of this utility model, buffer springs 16 are fixedly installed at the four bottom corners of multiple support plates 2. The ends of multiple buffer springs 16 away from the support plates 2 are fixedly connected to the hydraulic press body base 1. Multiple U-shaped frames 17 are fixedly installed on the outer sides of multiple support plates 2. Ball bearings are rotatably connected to multiple U-shaped frames 17. Fixing rods 18 are provided inside the hydraulic press body base 1 and located on the outer side of multiple support plates 2. Multiple fixing rods 18 are fixedly connected to the hydraulic press body base 1. Rollers are rotatably connected to the outer side of multiple fixing rods 18, and the rollers are slidably connected to the support plates 2.

[0042] Displacement sensors 15 are embedded in the top of multiple support blocks 4. Pressure sensors 14 are installed inside multiple hydraulic press body bases 1 and at the bottom of support plates 2. Multiple pressure sensors 14 are fixedly connected to hydraulic press body bases 1, and the output end of pressure sensors 14 is fixedly connected to support plates 2. A controller 21 is embedded in one side of hydraulic press body base 1. The controller 21 is electrically connected to the first electric telescopic rod 3, the second electric telescopic rod 13, the pressure sensor 14, the displacement sensor 15 and the third electric telescopic rod 19.

[0043] In this embodiment of the utility model, the ball bearings rotatably connected to the U-shaped frame 17 and the rollers rotatably connected to the outside of the fixed rod 18 change the sliding connection between the support plate 2 and the hydraulic press body base 1 to relative movement through the rolling ball bearings and rollers, and the rolling friction is much smaller than the sliding friction.

[0044] In this embodiment of the utility model, by providing buffer springs 16 at the bottom of multiple support plates 2, when the hydraulic press is subjected to an accidental impact or the hydraulic system malfunction causes the components to fall suddenly, the buffer springs 16 can absorb and disperse the impact force, reducing damage to the support device.

[0045] During the operation of this device, lower friction can make the movement of the support plate 2 smoother. When the weight of the hydraulic press slider or other additional force is transmitted to the support plate 2 through the support block 4, if the friction is too high, the movement of the support plate 2 may be obstructed, affecting the transmission path of the force. This may cause the pressure sensor 14 to be unable to accurately obtain the pressure value transmitted by the support block 4. At the same time, during long-term use of the device, low friction can reduce the wear of components and extend the service life of the device.

[0046] The components on the device are controlled by the controller 21. The pressure sensor 14 is used to monitor the pressure on the support device, and the displacement sensor 15 is used to detect the position change of the support device. The controller 21 performs real-time analysis and processing of the data from these sensors.

[0047] Working principle: The support block 4 is moved longitudinally by the synchronous operation of multiple first electric telescopic rods 3 to adjust the support height. During the support operation, the pressure sensor 14 is used to monitor the pressure on the support device, and the displacement sensor 15 is used to detect the position change of the support device. The controller 21 analyzes and processes the data of these sensors in real time, and then controls the multiple second electric telescopic rods 13 and third electric telescopic rods 19 set on the device.

[0048] When a heavy-duty hydraulic press is pressing large workpieces, multiple second electric telescopic rods 13 operate synchronously, causing the rack 12 to move laterally and mesh with the gear 11, which in turn drives the worm gears 9 on both sides of the connecting rod 10 to operate synchronously in the same direction. This causes the two adjacent worm wheels 8 to rotate in opposite directions, causing the corresponding side plates 5 on both sides of the support block 4 to rotate repulsively. Through the action of the auxiliary structure, the third electric telescopic rod 19 operates to push one of the auxiliary blocks 20. Through the cooperation of the rotating plate and the other auxiliary block 20, the two adjacent sliding plates 22 are moved repulsively, allowing the auxiliary support side plates 5 and the sliding plates 22 to unfold to a 45-degree angle with the ground, forming a stable triangular support structure that effectively disperses pressure and prevents the hydraulic press from tilting.

[0049] 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 way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
