Description

Technical Field

[0001] The utility model belongs to the technical field of brakes, and more specifically, particularly relates to a flywheel brake. Background Art

[0002] The press is a common processing device. When the press stops working, the flywheel will stop rotating when the power is cut off. However, due to the effect of inertia, the sub-wheel will continue to rotate, but the speed will gradually slow down until it finally stops rotating. In order to further ensure the safety of the operator and the stability of the equipment, it is necessary to use the flywheel brake to assist in controlling the movement of the flywheel so that the flywheel can stop immediately after the power is cut off. The flywheel brake is a device used to assist the flywheel to stop rotating. The existing flywheel brake is divided into two groups: dry clutch brake and wet clutch brake. However, the existing dry clutch brake is easy to generate heat during use. The accumulation of heat for a long time may cause the braking performance to decline, causing damage to the brake and reducing the service life. At the same time, the existing wet clutch brake generates friction by squeezing the friction plate and the coupling plate against each other. Due to the limited friction area, the existing wet clutch brake generates friction by squeezing the friction plate and the coupling plate against each other, so the generated braking force is delayed and not accurate enough, resulting in poor braking effect in emergency braking, affecting the safety and operability of the equipment. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a flywheel brake to solve the technical problems in the prior art that the existing dry clutch brake will generate a lot of heat when used, and long-term use will easily cause damage to the brake, thereby reducing its service life; at the same time, the existing wet clutch brake has a limited friction area, and the braking force generated is delayed and not precise enough, resulting in poor braking effect.

[0005] A flywheel brake comprises a main body shell, a piston assembly is arranged in the main body shell, a gas chamber is arranged between the piston assembly and the main body shell, an air inlet is opened on the main body shell, the gas chamber is connected with the outside through the air inlet, and the air inlet is connected with the external air source through a solenoid valve; a friction plate is arranged at one end of the main body shell, and the friction plate is installed on the piston assembly; a base is arranged under the main body shell, and the main body shell is connected to the base.

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0020] Example:

[0021] like Figures 1 to 3 As shown, the utility model provides a flywheel brake, wherein a piston assembly is arranged inside the main housing 11, and the piston assembly occupies an important position in the internal space of the main housing 11. In addition, a gas chamber is arranged between the piston assembly and the main housing 11, and an air inlet 12 is also provided on the main housing 11, so that the gas chamber can be smoothly connected with the outside through the air inlet 12, and the air inlet 12 is also connected with the external gas source through the solenoid valve, thereby forming a complete and effective gas transmission and control system. A friction plate 21 is arranged at one end of the main housing 11, and the friction plate 21 is installed on the piston assembly, and the friction plate 21 contacts the flywheel to realize the braking function. A base 13 is arranged below the main housing 11, and the main housing 11 and the base 13 are connected to ensure the stability and reliability of the entire structure.

[0022] like Figure 1 , 2As shown, the piston assembly includes a brake piston 31 and a piston rod 32. The brake piston 31 is clamped inside the main housing 11. A piston groove 33 is provided on the brake piston 31. The cover plate 34 is connected to the brake piston 31 by screws, and a movable cavity is formed between the cover plate 34 and the piston groove 33. The piston rod 32 is located at one end of the main housing 11, and one end thereof passes through the main housing 11 and the cover plate 34 and is located in the piston groove 33. This connection method is not only stable and reliable, but also provides a stable foundation for the smooth operation of the entire piston assembly. The piston rod 32 plays an effective limiting role, and the brake piston 31 moves along the piston rod 32.

[0023] A spring 35 is arranged in the movable chamber, and the spring 35 is sleeved on the piston rod 32, and one end of the spring 35 contacts the inner side of the cover plate 34. When the device is in operation, the brake piston 31 is pushed out, and the spring 35 is stretched. When the flywheel is braked, the solenoid valve is closed, and the gas in the gas chamber is discharged. The elasticity of the spring 35 automatically restores the brake piston 31, which is convenient for the next flywheel brake.

[0024] The brake piston 31 is provided with a mounting groove, the mounting block 36 is clamped in the mounting groove, the brake piston 31 and the mounting block 36 are provided with mounting holes respectively, the mounting bolts 37 are passed through these mounting holes, the brake piston 31 and the mounting block 36 are firmly connected together to form a stable whole. The friction plate 21 is installed on the mounting block 36, ensuring that the friction plate 21 can play the best braking effect when needed.

[0025] At the same time, a travel switch 41 is also installed on the main housing 11, and a pin 42 is provided at one end of the travel switch 41. One end of the pin 42 is connected to the mounting bolt 37. This connection is not only stable and reliable, but also can achieve accurate transmission of information and actions. The push-out distance of the friction plate 21 can be adjusted through the pin 42 and the travel switch 41 to adjust the braking force. Multiple groups of assembly holes 14 are provided on the base 13, and the assembly bolts are inserted into the assembly holes 14. The base 13 is connected to other devices through the assembly bolts.

[0026] The specific usage and function of this embodiment are as follows:

[0027] When in use, first, the flywheel brake is firmly connected to the assembly bolt and other equipment through the assembly hole 14 on the base 13 to ensure the stability of the overall structure. When the flywheel needs to be braked, the solenoid valve connected to the air inlet 12 is opened to allow the gas from the external air source to enter the gas chamber in the main shell 11 through the air inlet 12. The entry of gas pushes the brake piston 31 in the piston assembly to move along the piston rod 32. At this time, the mounting block 36 on the brake piston 31 drives the friction plate 21 to approach the flywheel and contact it, so that the brake can stop rotating immediately after power failure. When the flywheel stops, the solenoid valve is closed, the gas in the gas chamber is discharged, and under the elastic action of the spring 35, the brake piston 31 automatically recovers to prepare for the next flywheel auxiliary brake. At the same time, through the cooperation of the pin 42 and the travel switch 41, the position of the mounting bolt 37 can be adjusted, and then the push-out distance of the friction plate 21 can be adjusted, so as to accurately control the braking force.

[0028] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
