Description

Hydraulic device with buffer

Technical Field

The utility model relates to the field of hydraulic equipment, in particular to hydraulic equipment with buffering.

Background Art

A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the machine, the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

After searching, a utility model patent with publication number CN220095648U specifically discloses a hydraulic press buffer device, including a base, a connecting column fixedly connected to the top of the connecting column, a top plate fixedly connected to the top of the connecting column, a hydraulic cylinder fixedly connected to the bottom of the top plate, a buffer mechanism is provided on the outer side of the hydraulic cylinder, the buffer mechanism includes a buffer column, the buffer column is fixedly connected to the outer wall of the hydraulic cylinder, a buffer groove is provided inside the buffer column, six fixed rods are fixedly connected to the inside of the buffer groove in a circular array, springs are sleeved on the outer sides of the six fixed rods, and a lifting plate is slidably connected to the bottom of the buffer column. The beneficial effect of the utility model is that the rising speed of the hydraulic head is slowed down, thereby achieving buffering of the hydraulic press, protecting the safety of the hydraulic head during use, avoiding collision between the hydraulic head and the hydraulic cylinder body, and also protecting the safety of the staff, increasing the service life of the hydraulic press, and having strong practicality.

In the above patent, the speed of the hydraulic head in the rising process is slowed down by a buffer structure to achieve buffering of the hydraulic press. Since the lifting speed of the hydraulic equipment itself is controllable and can be controlled by oil pressure, the rising speed is slowed down by the installed spring in the above patent to prevent the cylinder and the hydraulic head from colliding. However, this method may cause the spring to be squeezed and deformed. In the above patent, since the hydraulic head needs to process the parts on the processing table, the downward pressure of the hydraulic head is generally large, so the processing table is an important position of the entire equipment that needs buffering. Since the processing table itself does not have an effective buffer structure, the table surface will vibrate during the downward pressure process, causing the position of the processed parts to deviate, affecting the yield of the parts.

Therefore, it is necessary to invent a hydraulic device with buffering to solve the above problems.

Utility Model Content

The utility model aims to provide a hydraulic device with buffering, which can reduce the vibration of a processing table and protect two groups of springs by setting a spring one and a spring two and setting a limit block and a limit groove, so as to solve the problem in the prior art that the processing table vibrates and the springs are easily damaged when the buffering is reduced.

In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydraulic equipment with buffering, comprising a base, a support leg installed at the bottom of the base, a support column installed above the base, a control panel installed on one side of the support column, a hydraulic head connected to the bottom of the control panel, a buffer structure arranged above the base, and a processing table installed above the buffer structure.

Preferably, the buffer structure comprises: a connecting platform, the connecting platform is installed above the base, a cavity is opened in the connecting platform, and a telescopic rod is installed in the cavity.

Preferably, a spring 1 is fitted and connected above the telescopic rod, a processing table is fitted and connected above the spring 1, the processing table is fixedly connected to the output end of the telescopic rod, the spring 1 is sleeved with the output end of the telescopic rod, and three groups of telescopic rods are evenly arranged in the cavity.

Preferably, a limiting block is fixedly connected to one side of the processing table, and the limiting blocks are installed on both sides of the processing table. A limiting groove is opened on the inner wall of the cavity, and the stroke of the limiting groove is smaller than the telescopic length of the telescopic rod. The limiting groove is slidably connected to the limiting block.

Preferably, a connecting plate is welded to one side of the connecting platform, the bottom of the connecting plate is bolted to the top of the reinforcement, and the side of the reinforcement is bolted to the side of the connecting platform.

Preferably, a sliding rod frame is installed above the connecting plate, and a slider is slidably connected to the sliding rod frame. A second spring is fit-connected to one side of the slider, and one side of the second spring is fit-connected to the sliding rod frame. The second spring is sleeved with the sliding rod on the sliding rod frame. A push rod is rotatably connected above the slider, and the push rod is rotatably connected to one side of the processing table at a connection away from the slider.

In the above technical solution, the technical effects and advantages provided by the utility model are:

1. Through the setting of the connecting table, cavity, telescopic rod, spring 1, limit block, limit groove, connecting plate, reinforcement, slide bar frame, slider, spring 2 and push rod, the hydraulic head presses down to apply force to the processing table. At this time, the processing table will transmit the force to the telescopic rod and shrink it, and slow down the shrinkage speed of the telescopic rod through the action of spring 1. When the processing table moves downward, the slider will be driven by the push rod to slide along the slide bar frame and squeeze spring 2 for buffering assistance. Through the two sets of buffer structures, the processing table can be effectively buffered, and due to the setting of the limit block and the limit groove, the telescopic rod will not be completely contracted, so that the telescopic rod and spring 1 can be protected and the buffering effect is not affected. In this way, the processing table can be buffered to reduce the vibration during parts processing and improve the yield rate of parts.

As shown in Figures 1, 2 and 4, the buffer structure includes: a connecting platform 5, which is installed above the base 1, and a cavity 6 is opened in the connecting platform 5, and a telescopic rod 7 is installed in the cavity 6.

As shown in Fig. 1-4, a spring 8 is attached to the top of the telescopic rod 7, a processing table 9 is attached to the top of the spring 8, the processing table 9 is fixedly connected to the output end of the telescopic rod 7, the spring 8 is sleeved with the output end of the telescopic rod 7, and three groups of telescopic rods 7 are evenly arranged in the cavity 6. The spring 8 above the telescopic rod 7 can slow down the contraction speed of the telescopic rod 7.

As shown in Fig. 1-4, a limit block 10 is fixedly connected to one side of the processing table 9, and the limit blocks 10 are installed on both sides of the processing table 9. A limit groove 11 is provided on the inner wall of the cavity 6. The stroke of the limit groove 11 is less than the telescopic length of the telescopic rod 7. The limit groove 11 is slidably connected to the limit block 10. The limit block 10 and the limit groove 11 can ensure that the spring 8 will not be damaged during the buffering process.

As shown in Figures 1, 2 and 4, a connecting plate 12 is welded to one side of the connecting platform 5, the bottom of the connecting plate 12 is bolted to the top of the reinforcement 13, and the side of the reinforcement 13 is bolted to the side of the connecting platform 5. The reinforcement 13 can make the connecting plate 12 have better support.

As shown in Figures 1, 3 and 4, a slide bar frame 14 is installed above the connecting plate 12, and a slider 15 is slidably connected to the slide bar frame 14. A spring 2 16 is fitted and connected to one side of the slider 15, and one side of the spring 2 16 is fitted and connected to the slide bar frame 14.
