Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, specifically to a vibration suppression and buffer device for a six-sided hydraulic press. Background Technology

[0002] In modern industrial production, hydraulic presses are an important processing equipment widely used in metal forming, forging, stamping and other fields. With their ability to provide strong and stable pressure, they meet the pressure and precision requirements of various complex processes and have become an indispensable production tool for many manufacturing enterprises. However, hydraulic presses inevitably generate vibration problems during operation.

[0003] During stamping operations, existing hydraulic presses rapidly apply enormous pressure through the hydraulic cylinders. Due to the lack of an effective buffering mechanism, the stamping pressure acts directly on the workpiece and equipment structure, causing strong vibrations throughout the equipment. This vibration not only generates high-decibel noise, interfering with the production environment and affecting the physical and mental health of operators, but also causes serious damage to the equipment itself. Under prolonged vibration, key components of the hydraulic press, such as the frame and hydraulic cylinders, are prone to fatigue cracks and loose connections, reducing the precision and stability of the equipment, shortening its service life, and increasing the maintenance and replacement costs for enterprises. Therefore, those skilled in the art provide a six-sided hydraulic press vibration suppression and buffering device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a vibration suppression and buffer device for a six-sided hydraulic press, thereby solving the problems mentioned in the background art.

[0006] Preferably, the four corners of the top of the mounting base are fixedly connected to support columns, the top of the four support columns are fixedly connected to a top plate, and a hydraulic cylinder for stamping the stamped part is fixedly connected to the center of the bottom of the top plate.

[0007] Preferably, each set of buffer mechanisms includes a buffer cylinder symmetrically fixedly connected to the mounting base with its top end located inside a square groove. Each buffer cylinder has a piston slidably sleeved inside. The upper top end of each piston is fixedly connected to a piston rod, and the upper top ends of the two piston rods are fixedly connected to the lower bottom end of the placement plate.

[0008] Preferably, the outer side wall of the mounting base has two symmetrical placement slots, and each placement slot contains an exhaust tee pipe. A solenoid valve is installed on the outer wall of the exhaust tee pipe near the two buffer cylinders. One end of the exhaust tee pipe is connected to the exhaust end of the two buffer cylinders respectively, and the other end is connected to the extrusion assembly.

[0009] Preferably, air pumps are symmetrically fixedly connected to the outer wall of the mounting base, and an air supply tee is fixedly connected to the exhaust end of each air pump. The other two ends of the air supply tee are connected to the air inlet ends of two buffer cylinders. A one-way valve is installed on the outer wall of the air supply tee on one side of two of the buffer cylinders.

[0010] Preferably, each set of the extrusion assembly includes a fixed plate fixedly connected to the mounting base at the center of the square groove at its top. An airbag body is fixedly connected to the top of the fixed plate. Two fixed brackets are symmetrically fixedly connected to the outer side wall of the fixed plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention incorporates a buffer mechanism. The stamped part is placed on the top of the placement plate, and the extension end of the hydraulic cylinder impacts the stamping force. The pressure acts on the stamped part, and the pressure sensor, sensing the pressure, sends a command to the control console. The control console then opens the solenoid valve. Under the influence of the stamping force, the piston and piston rod inside the buffer cylinder descend, compressing the gas inside the buffer cylinder, thus achieving a buffering effect. Due to the opening of the solenoid valve, the gas, under pressure, is discharged from the exhaust tee into the compression assembly, causing the air bladder in the compression assembly to automatically expand and lift the placement plate, preventing excessive pressure and damage to the buffer mechanism. This method achieves the buffering effect. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a vibration suppression and buffering device for a six-sided hydraulic press, including a base 1, a mounting seat 3 fixedly connected to the upper top of the base 1, a control console 2 fixedly connected to one side of the mounting seat 3 at the upper top of the base 1, square grooves 10 symmetrically opened at the upper top of the mounting seat 3, a placement plate 8 for placing stamping parts is provided above the mounting seat 3, two pressure sensors 9 for sensing the stamping force are symmetrically fixedly connected to the upper top of the placement plate 8, buffering mechanisms 6 for buffering the pressure of the placement plate 8 are provided inside the two square grooves 10 at the upper top of the mounting seat 3, and a pressing component 7 for pressing the placement plate 8 is provided between every two sets of buffering mechanisms 6 at the upper top of the mounting seat 3.

[0023] It should be noted that the base 1 provides stable support for the entire device, and the mounting base 3 is fixed on it. Together with the control console 2, it facilitates operation and control. The placement plate 8 is used to place the stamped parts. Two pressure sensors 9 are symmetrically arranged on it, which can sense the pressure of the stamped parts on the placement plate 8 in real time and provide accurate data feedback. This helps to grasp the stamping situation in a timely manner and ensure the accuracy and safety of the stamping operation. The square groove 10 symmetrically opened at the top of the mounting base 3 is equipped with a buffer mechanism 6. During the stamping process, it can effectively buffer the pressure borne by the placement plate 8, reduce vibration transmission, reduce wear and noise caused by vibration, extend the service life of the equipment, and at the same time ensure the processing quality of the stamped parts. The extrusion assembly 7 is used to extrude the placement plate 8. Together with the buffer mechanism 6, it realizes the stamping action. Under the buffering effect of the buffer mechanism 6, the extrusion assembly 7 runs more smoothly, reduces stamping deviation caused by vibration, and improves stamping accuracy. The model of the pressure sensor 9 can be MPX5010DP (not specifically specified).

[0024] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, support columns 4 are fixedly connected to the four corners of the top of the mounting base 3. The top of the four support columns 4 are fixedly connected to the top plate 5. A hydraulic cylinder 51 for stamping the stamped parts is fixedly connected to the center of the bottom of the top plate 5.

[0025] It should be noted that the support columns 4 fixedly connected to the four corners of the top of the mounting base 3 provide a stable support frame for the entire stamping structure, ensuring stability during the stamping process and reducing errors caused by structural swaying. The top plate 5 fixed to the top of the four support columns 4 serves as a load-bearing platform for the upper structure, making the installation of the hydraulic cylinder 51 more stable and reliable. The hydraulic cylinder 51 fixed at the center of the bottom end of the top plate 5 can accurately perform stamping operations on the stamped parts. The hydraulic cylinder 51 is located in the center position, which can make the stamping pressure evenly distributed, avoiding deformation or damage to the stamped parts due to uneven stamping pressure, and improving the stamping quality.

[0026] As one implementation method in this embodiment, please refer to Figure 3 - Figure 5As shown, each buffer mechanism 6 includes a buffer cylinder 61 symmetrically fixedly connected to the mounting base 3 with its top end located inside the square groove 10. A piston 611 is slidably sleeved inside each buffer cylinder 61. A piston rod 62 is fixedly connected to the upper top end of each piston 611. The upper top ends of the two piston rods 62 are fixedly connected to the lower bottom end of the placement plate 8. Two placement grooves 11 are symmetrically opened on the outer wall of the mounting base 3. An exhaust tee pipe 66 is placed inside each placement groove 11. The outer wall of the exhaust tee pipe 66 is close to the two... A solenoid valve 67 is installed on one side of the buffer cylinder 61. Two ends of the exhaust tee pipe 66 are respectively connected to the exhaust ends of the two buffer cylinders 61, and the other end is connected to the extrusion assembly 7. Air pumps 63 are symmetrically fixedly connected to the outer wall of the mounting base 3. Each air pump 63 has an exhaust end fixedly connected to an air supply tee pipe 64. The other two ends of the air supply tee pipe 64 are connected to the air inlet ends of the two buffer cylinders 61. A one-way valve 65 is installed on the outer wall of the air supply tee pipe 64 on one side of two of the buffer cylinders 61.

[0027] It should be noted that the buffer cylinder 61 is symmetrically fixed inside the square groove 10, and the piston 611 is slidably sleeved in it. The piston rod 62 connects the piston 611 and the placement plate 8. This structure allows the buffer cylinder 61 to effectively buffer the pressure on the placement plate 8 during stamping, reduce vibration transmission, ensure the processing quality of the stamped parts, and reduce the wear of the equipment caused by vibration. The air pump 63 supplies air to the buffer cylinder 61 through the air supply tee pipe 64. The one-way valve 65 on the outer wall of the air supply tee pipe 64 can prevent gas backflow and ensure stable air supply, so that the buffer cylinder 61 can continuously provide buffering force and ensure the smoothness of the stamping process. The exhaust tee pipe 66 is placed in the placement groove 11 and connected to the exhaust end of the buffer cylinder 61. The solenoid valve 67 can control the exhaust, so that the gas in the buffer cylinder 61 can be discharged in time after the stamping is completed, which is convenient for the next stamping operation and improves work efficiency.

[0028] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, each compression assembly 7 includes a fixed plate 71 fixedly connected to the mounting base 3 at the center of the square groove 10. An airbag body 72 is fixedly connected to the top of the fixed plate 71. Two fixed brackets 73 are symmetrically fixedly connected to the outer side wall of the fixed plate 71. Guide rods 74 are slidably sleeved inside the two fixed brackets 73. The top of the two guide rods 74 is fixedly connected to the bottom of the placement plate 8. The air inlet end of the airbag body 72 is connected to the other end of the exhaust three-way pipe 66. An electronically controlled exhaust valve 721 is fixedly installed at the exhaust end of the airbag body 72. A maintenance plate 12 is bolted to the outer wall of the mounting base 3 at the position of the placement groove 11.

[0029] It should be noted that the fixing plate 71 is fixed at the center of the square groove 10, providing stable support for the airbag body 72. The air inlet end of the airbag body 72 is connected to the exhaust tee pipe 66, which can utilize the air source of the buffer mechanism 6 to realize the recycling of gas. When the airbag body 72 is inflated, it can apply a uniform upward compressive force to the placement plate 8. In conjunction with the stamping action, it ensures that the stamped part is subjected to uniform force and improves the stamping quality. The fixing bracket 73 is slidably sleeved with the guide rod 74. The guide rod 74 is connected to the placement plate 8. During the compression process of the airbag body 72, the guide rod 74 can guide the placement plate 8 to move smoothly, reduce deviation and shaking, and further improve the stamping accuracy. The electrically controlled exhaust valve 721 is installed at the exhaust end of the airbag body 72, which can accurately control the timing and speed of the exhaust of the airbag body 72, and facilitates flexible adjustment of the stamping rhythm.

[0030] Working principle: During the stamping operation, the stamping part is placed on the top of the placement plate 8. The hydraulic cylinder 51 is started, and its extension end impacts downward to apply pressure to the stamping part. The pressure is transmitted to the placement plate 8 through the stamping part. At this time, the two pressure sensors 9 at the top of the placement plate 8 sense the pressure and send the signal to the control console 2. After receiving the signal, the control console 2 controls the solenoid valve 67 to open.

[0031] Under the action of the hydraulic cylinder 51, the piston 611 inside the buffer cylinder 61 of the buffer mechanism 6 in the square groove 10 drives the piston rod 62 to descend, compressing the gas inside the buffer cylinder 61, which plays a buffering role and reduces vibration transmission. As the solenoid valve 67 is opened, the pressurized gas inside the buffer cylinder 61 is discharged from the exhaust end through the exhaust three-way pipe 66 and enters the airbag body 72 of the extrusion assembly 7. The air inlet end of the airbag body 72 is connected to the exhaust three-way pipe 66. After the gas enters, it automatically expands. The airbag body 72 plays a lifting role on the placement plate 8, sharing part of the pressure and avoiding excessive pressure that could damage the buffer mechanism 6. At the same time, the fixing bracket 73 on the outer wall of the fixing plate 71 in the extrusion assembly 7 is slidably sleeved with the guide rod 74. The guide rod 74 is connected to the placement plate 8 to ensure that the placement plate 8 moves smoothly.

[0032] After the stamping is completed, the exhaust is controlled by the electrically controlled exhaust valve 721 at the exhaust end of the airbag body 72 to facilitate the next operation.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
