Description

Technical Field

[0001] The utility model relates to the technical field related to shock absorption of hydraulic presses, in particular to a hydraulic press equipped with a shock absorbing buffer. Background Art

[0002] A hydraulic press is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the oil cylinder through the hydraulic pipeline by the force of the pump. Then there are several sets of seals in the oil cylinder that cooperate with each other. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to circulate the oil cylinder to do work, thereby completing a certain mechanical action as a productivity machine.

[0003] When working, a large impact force will be generated on the foundation, which is easy to damage the foundation and the hydraulic press. In the prior art, the patent with announcement number CN210566010U discloses a shock-absorbing mounting structure for a hydraulic press, including a mounting seat installed in the foundation, a mounting groove is opened on the mounting seat, and a mounting plate for mounting the hydraulic press is installed on the upper part of the mounting groove. A vertical supporting shock-absorbing mechanism is installed in the vertical direction between the mounting plate and the mounting seat, and a horizontal shock-absorbing mechanism is installed in the horizontal direction between the mounting seat and the foundation. A locking mechanism that can lock the mounting seat is also installed on the foundation. This structure can reduce the impact of the hydraulic press on the foundation in the vertical and horizontal directions respectively through the vertical support shock-absorbing mechanism and the horizontal shock-absorbing mechanism. It has the advantage of reducing the damage to the foundation and the hydraulic press caused by the vibration of the foundation driven by the hydraulic press. However, the following problems are still found during use. This structure only achieves shock absorption and buffering through shock-absorbing springs. The shock-absorbing springs will become fatigued after long-term use and are inconvenient to replace. At the same time, the shock absorption form of this structure is single and the reusability effect is poor. For this reason, technical personnel in this field have proposed to add shock-absorbing buffers to the hydraulic press to solve the problems raised in the above background. Utility Model Content

[0004] The purpose of the utility model is to provide a hydraulic press equipped with a shock absorbing buffer to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The hydraulic press is equipped with a shock-absorbing buffer, which includes a buffer base, wherein the buffer base is arranged on the side of the lower bed of the hydraulic press, and the side of the upper slider of the hydraulic press is connected with an upper impact block of the buffer, and the upper impact block of the buffer is arranged directly above the buffer base. The interior of the buffer base is divided into a buffer inner cavity and a buffer outer cavity, and the buffer outer cavity is cylindrical and is located at the periphery of the buffer inner cavity. A buffer spring is installed in the buffer inner cavity, and a collision head is installed on the top of the buffer base. The bottom end of the collision head extends to the top of the buffer inner cavity and is connected to the top of the buffer spring. The buffer outer cavity is filled with hydraulic oil, and the top of the buffer outer cavity is connected to the bottom of the buffer inner cavity.

[0007] As a further solution of the utility model: a buffer cover is detachably mounted on the top of the buffer base, the middle portion of the buffer cover is interlaced and connected with the impacted head, and a buffer refueling port is arranged on the side of the buffer cover.

[0008] As a further solution of the utility model: a buffer sealing ring is provided at the connection between the top end of the buffer cover plate and the impacted head, and a sealing ring fastening block is installed on the top of the buffer sealing ring.

[0009] As a further solution of the utility model: one side of the buffer inner cavity is connected to the buffer outer cavity through a buffer pressure regulating valve, and the other side of the buffer inner cavity is connected to the buffer outer cavity through a buffer check valve.

[0010] As a further solution of the utility model: buffer fixing brackets are connected to both sides of the lower bed of the hydraulic press, and the buffer base is installed on the buffer fixing brackets.

[0011] As a further solution of the utility model: an impact head cooperating with the impacted head is installed at the bottom end of the impact block on the buffer.

[0012] As a further solution of the utility model: the bottom end of the impacted head is connected with a raised column, and the raised column is inserted into the top inner periphery of the buffer spring.

[0013] The utility model has the following benefits:

[0014] 1. When the slider on the hydraulic press descends and the impact block on the buffer presses the impacted head, the impacted head will be pushed and move downward, and the hydraulic oil in the buffer cavity slowly flows from the inner cavity to the outer cavity of the buffer through the buffer pressure regulating valve. At this time, the buffer check valve is in a closed state, which plays a role in buffering and shock absorption during the trimming process. When the hydraulic press rises, the impact block on the buffer separates from the impacted head, and the impacted head moves upward under the action of the buffer spring. At this time, the buffer check valve automatically opens, and the hydraulic oil in the outer cavity flows into the inner cavity through the buffer check valve. This setting can realize the automatic reset of the impacted head, and the cooperation of the buffer spring and the hydraulic oil can achieve a better shock absorption and buffering effect;

[0015] 2. The buffer spring is arranged in the inner cavity of the buffer and is covered by hydraulic oil. The hydraulic oil can protect the buffer spring and place the buffer spring directly exposed to the air, which increases the service life of the buffer spring. The impact head and the buffer spring can be disassembled and assembled through the buffer cover, making maintenance more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0022] Example 1: Please refer to Figures 1 to 3The oil hydraulic press is equipped with a shock-absorbing buffer, including a buffer base 7, which is arranged on the side of the lower bed 9 of the oil hydraulic press, and the side of the upper slider 1 of the oil hydraulic press is connected with a buffer upper impact block 2, and the buffer upper impact block 2 is arranged directly above the buffer base 7. The interior of the buffer base 7 is divided into a buffer inner cavity 6 and a buffer outer cavity 11, and the buffer outer cavity 11 is cylindrical and located at the periphery of the buffer inner cavity 6. The buffer inner cavity 6 is cylindrical, and a buffer spring 15 is installed in the buffer inner cavity 6. The top of the buffer base 7 is installed with a collision head 3, and the bottom end of the collision head 3 extends to the top of the buffer inner cavity 6 and is connected to the top of the buffer spring 15. The buffer outer cavity 11 is filled with hydraulic oil, and the top of the buffer outer cavity 11 is connected to the bottom of the buffer inner cavity 6. When the buffer upper impact block 2 squeezes the collision head 3, the collision head 3 will squeeze the buffer spring 15, and at the same time squeeze part of the hydraulic oil in the buffer inner cavity 6 into the buffer outer cavity 11.

[0023] See also Figures 1 to 3 A buffer cover 5 is detachably mounted on the top of the buffer base 7, the middle portion of the buffer cover 5 is interlaced and connected with the impacted head 3, a buffer refueling port 12 is arranged on the side of the buffer cover 5, in order to improve the connection sealing between the impacted head 3 and the buffer cover 5, a buffer sealing ring 13 is arranged at the connection between the top of the buffer cover 5 and the impacted head 3, a sealing ring fixing block 4 is installed on the top of the buffer sealing ring 13, and the sealing ring fixing block 4 is installed on the top of the buffer cover 5 by means of inlay installation.

[0024] Please refer to Figure, Figure 3 One side of the buffer inner cavity 6 is connected to the buffer outer cavity 11 through the buffer pressure regulating valve 8, and the other side of the buffer inner cavity 6 is connected to the buffer outer cavity 11 through the buffer check valve 10. The buffer pressure regulating valve 8 can make the hydraulic oil in the buffer inner cavity 6 flow slowly to the buffer outer cavity 11, and the buffer check valve 10 can restore the hydraulic oil liquid level height of the buffer inner cavity 6 and the buffer outer cavity 11 when the impacted head 3 is reset.

[0025] Example 2: See Figure 1 , Figure 2 On the basis of the first embodiment, buffer fixing brackets 14 are connected to both sides of the lower bed surface 9 of the hydraulic press, the buffer base 7 is installed on the buffer fixing bracket 14, the buffer base 7 is set in two to achieve a shock-absorbing and buffering effect, and the bottom end of the impact block 2 on the buffer is installed with an impact head that cooperates with the impacted head 3.

[0026] See also Figure 2 , Figure 4The bottom end of the impacted head 3 is connected with a raised column 16, and the raised column 16 is inserted into the inner periphery of the top of the buffer spring 15. This arrangement improves the connection stability between the impacted head 3 and the top of the buffer spring 15.

[0027] Working principle: When in use, the slider 1 on the hydraulic press descends and drives the impact block on the buffer to squeeze the impacted head 3. The impacted head 3 moves downward after being pressurized, and the hydraulic oil in the buffer inner cavity 6 slowly flows from the inner cavity to the buffer outer cavity 11 through the buffer pressure regulating valve 8. At this time, the buffer check valve 10 is in a closed state, thereby realizing shock absorption and buffering of the slider 1 on the hydraulic press. When the hydraulic press rises, the impact block 2 on the buffer separates from the top of the impacted head 3, and the impacted head 3 moves upward under the action of the buffer spring 15. At this time, the buffer check valve 10 opens automatically, and the hydraulic oil in the outer cavity flows into the inner cavity through the buffer check valve 10, thereby realizing the reset of the buffer spring 15 and the hydraulic oil level.
