Description

Technical Field

[0001] This utility model relates to the field of friction press balance cylinder technology, specifically to a pressure boosting device for a friction press balance cylinder. Background Technology

[0002] A friction press is a screw press that uses friction drive, also known as a double-disc friction press. It utilizes the contact transmission between the flywheel and the friction disc, and works by relying on the relative motion principle between the screw and the copper nut. In traditional friction presses, pneumatic balance cylinders are mostly used to reduce the upward impact force of the slide and ensure the stability of the up and down movement. However, balance cylinders have problems such as large impact force and unstable operation, which makes it impossible to overcome the problem of the upper slide's own weight. Utility Model Content

[0003] The purpose of this invention is to provide a pressure boosting device for the balance cylinder of a friction press to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pressure boosting device for a friction press balance cylinder, comprising a balance cylinder body, a cylinder cover fixedly mounted at the lower end of the balance cylinder body, a piston inserted into the inner wall of the balance cylinder body, a drive rod fixedly mounted at the lower end of the piston, the drive rod passing through the cylinder cover and screwed with a lifting structure, a buffer structure fixedly connected to the side wall of the cylinder cover, and a flexible air tube screwed to the outer end of the buffer structure.

[0005] Preferably, the buffer structure includes a connecting pipe, one end of which is fixedly connected to the cylinder head, and the other end of which is fixedly connected to an air cylinder. The upper end of the air cylinder is provided with a groove, and an electric telescopic rod is fixedly installed in the groove. The piston rod end of the electric telescopic rod passes through the air cylinder and is fixedly connected to a stop block. The stop block covers the periphery of the connecting pipe and blocks it. A connecting rod is fixedly installed on the side wall of the stop block. The connecting rod is located inside the connecting pipe, and a blocking block is fixedly installed on the upper end of the connecting rod. A connector is fixedly connected to the outer wall of the connecting pipe through a bypass pipe. One end of the connector is fixedly connected to the air cylinder, and a flexible air tube is screwed to the inner wall of the other end of the connector. When the stop block is close to the connecting pipe, the blocking block is located on one side of the bypass pipe.

[0006] Preferably, the hoisting structure includes a screw sleeve, which is screwed to the lower outer wall of the drive rod, and a lifting ring is fixedly fitted to the lower end of the screw sleeve.

[0007] Preferably, a limiting plate is fixedly mounted on the outer wall of the piston rod of the electric telescopic rod, and the setting position of the limiting plate corresponds to the displacement distance of the block.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The cylinder body and cylinder head of the balance cylinder are assembled to form a sealed space, which is coordinated with the piston to adjust the position of the drive rod. The piston is driven by gas. The gas source enters the cylinder body of the balance cylinder through the buffer structure to drive the piston. The pump in the pneumatic system converts the gas pressure into pneumatic energy, which is transmitted to the working chamber of the balance cylinder through the pneumatic pipeline, i.e., the soft air pipe. The pneumatic pressure acts on the piston. Due to the structural settings on both sides of the piston and the connection with other components, the drive rod drives the slider in the friction press to move through the hoisting structure. When the slider moves upward, the balance cylinder can provide sufficient balancing force to overcome the weight of the upper slider. However, traditional balance cylinders have large impact force, unstable operation and poor stability during use. The buffer structure in this application can reduce the movement speed of the piston by adjusting the gas flow, thereby reducing the impact force and making it highly practical.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5This utility model provides a pressure boosting device for a friction press balance cylinder, including a balance cylinder body 1, a cylinder cover 2 fixedly mounted on the lower end of the balance cylinder body 1, a piston 3 inserted into the inner wall of the balance cylinder body 1, a drive rod 4 fixedly mounted on the lower end of the piston 3, the drive rod 4 passing through the cylinder cover 2 and screwed with a lifting structure 5, a buffer structure 6 fixedly connected to the side wall of the cylinder cover 2, and a flexible air tube 7 screwed to the outer end of the buffer structure 6.

[0017] The cylinder body 1 and cylinder head 2 of the balance cylinder are assembled to form a sealed space. The position of the drive rod 4 is adjusted in conjunction with the piston 3. The piston 3 is driven by gas. The gas source enters the cylinder body 1 of the balance cylinder through the buffer structure 6 and drives the piston 3. The pump in the pneumatic system converts the gas pressure into pneumatic energy, which is transmitted to the working chamber of the balance cylinder through the pneumatic pipeline, i.e., the flexible air pipe 7. The pneumatic pressure acts on the piston 3. Due to the structural settings on both sides of the piston 3 and its connection with other components, the drive rod 4 drives the slider in the friction press to move through the lifting structure 5. When the slider moves upward, the balance cylinder can provide sufficient balancing force to overcome the weight of the upper slider. However, traditional balance cylinders have large impact force, unstable operation, and poor stability during use. In this application, the buffer structure 6 can slow down the movement speed of the piston 3 by adjusting the gas flow rate, thereby reducing the impact force and making it highly practical.

[0018] The buffer structure 6 includes a connecting pipe 61. One end of the connecting pipe 61 is fixedly connected to the cylinder head 2, and the other end of the connecting pipe 61 is fixedly connected to an air cylinder 62. The upper end of the air cylinder 62 is provided with a groove, and an electric telescopic rod 63 is fixedly installed in the groove. The piston rod end of the electric telescopic rod 63 passes through the air cylinder 62 and is fixedly connected to a stop block 66. The stop block 66 covers the periphery of the connecting pipe 61 and blocks it. A connecting rod 67 is fixedly installed on the side wall of the stop block 66. The connecting rod 67 is located inside the connecting pipe 61, and a blocking block 68 is fixedly installed on the upper end of the connecting rod 67. The outer side wall of the connecting pipe 61 is fixedly connected to a connector 64 through a bypass pipe 65. One end of the connector 64 is fixedly connected to the air cylinder 62, and a flexible air tube 7 is screwed onto the inner wall of the other end of the connector 64. When the stop block 66 is close to the connecting pipe 61, the blocking block 68 is located on one side of the bypass pipe 65.

[0019] When a large amount of gas enters or exits the balance cylinder 1, the impact force is significant, which can lead to unstable operation. In this case, if... Figure 5In the indicated state, the route from connecting pipe 61 to air cylinder 62 is blocked. Gas needs to enter the connector 64 through bypass pipe 65, and then enter the flexible air tube 7 through the suction of the pump body and be discharged to the gas source. Conversely, gas enters the bypass pipe 65 through the flexible air tube 7 and connector 64, and then enters the connecting pipe 61 through the bypass pipe 65. At this time, the gas travels a smaller path and the flow rate is slower, so the displacement speed of piston 3 is also slower. At this time, the drive rod 4 will move evenly and slowly to ensure stability. When normal exhaust is required, the electric telescopic rod 63 is opened to adjust the stop block 66 away from the connecting pipe 61. At this time, the stop block 66 will drive the block block 68 through the connecting rod 67, so that it blocks the bottom of the bypass pipe 65. Gas enters the connector 64 through the large-path air cylinder 62 and is discharged to the flexible air tube 7.

[0020] The hoisting structure 5 includes a screw sleeve 51, which is screwed to the lower outer wall of the drive rod 4, and a lifting ring 52 is fixedly mounted on the lower end of the screw sleeve 51.

[0021] The screw sleeve 51 is screwed to the drive rod 4, making it easy to remove the lifting ring 52 for replacement and maintenance.

[0022] A limit plate is fixedly mounted on the outer wall of the piston rod of the electric telescopic rod 63, and the position of the limit plate corresponds to the displacement distance of the block 68.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
