Flexible clutch-braking method of press clutch brake

Abstract

The invention relates to a flexible braking system of a press clutch in the technical field of presses. An upper branch of an air outlet pipeline of an air storage tank is connected with a clutch airsupply pipeline and a brake air supply pipeline. The flexible braking system is characterized in that a front section branch of the clutch air supply pipeline is provided with a soft clutch branch anda fast clutch branch, a rear section of a clutch air supply pipeline which is formed by gathering air outlet ends of the soft clutch branch and the fast clutch branch is connected to a clutch cylinder through a first duplex valve, and the air supply channel, between the clutch air cylinder and the first duplex valve, is further connected with a first pressure sensor; and a second duplex valve, asecond pressure sensor and a brake cylinder are sequentially connected on the brake air supply pipeline. According to the flexible braking system, due to the fact that the clutch is in a soft clutch state, the instantaneous acting force of the clutch, in combination time, is reduced, the damage of the mechanical structure of the clutch is reduced, and the service life of the mechanical structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a flexible clutch braking method of a flexible braking system of a clutch of a press. Background technique [0002] The mechanical press is a general-purpose forging equipment, which can perform almost all stamping processes, such as sheet blanking, drawing forming, hot and cold extrusion, etc. Clutches and brakes are the key components of the entire press, and their main functions are to quickly combine or disconnect the energy part and the driven part of the main transmission system, and to make the driven part Quickly brake, so as to control the production rhythm and ensure the safety of people and equipment. The clutch and brake are the components that control the movement or stop of the crank slider mechanism of the press when the motor and the flywheel are constantly rotating. A critical component to prevent accidents, improve quality and productivity. Therefore, its perf...

Problems solved by technology

[0005] The present invention aims at the unclear disengagement problem in the pneumatic system of the clutch and brake of the mechanical press in the prior art, and provides a flexible clutch-brake method for the clutch and brake of the press, so as to overcome the clutch and brake disengagement. clear question

[0007] In the flexible clutch-braking method of the present invention, during the clutching process, by controlling the intake flow rate of the brake cylinder to be greater than the intake flow rate of the clutch cylinder, the time for the brake to be disengaged is earlier than the clutch engagement time, so as to solve the problem of interference when the clutch brake starts Problem: During the braking process, by controlling the exhaust flow rate of the clutch cylinder to be greater than the exhaust flow rate of the brake cylinder, the clutch disengagement time is earlier than the brake engagement time, so as to solve the problem of clutch and brake interference during braking
