Embodiment Construction

[0006] The present invention will be further described below in conjunction with accompanying drawing:

[0007] See accompanying drawing 1, the mounting plate (14) of a dial-out type emergency braking device is fixed on the bed between the flywheel and the bed, and one end of the ratchet lever (5) is flexibly fixed on the mounting plate through a pin (15). On the plate (14), the solenoid valve (3) is fixed on the mounting plate (14), and the ratchet of the ratchet (9) on the outer periphery of the crankshaft sleeve (13) meshes with the ratchet of the ratchet lever (5). , the ratchet driving rod (5) offsets the ratchet driving nail (6) at the ratchet upper end of the ratchet driving rod (5), and the other end of the ratchet driving rod (5) is connected to the connecting rod (4) through a pin shaft, and the The other end of the rod (4) is connected to the solenoid valve (3), and a spring (1) is arranged between the spring fixing plate (2) fixed on the mounting plate (14) and the...

Abstract

The invention discloses an outward toggling type emergency brake gear which comprises a solenoid valve, a mounting plate, a connection rod, a shift lever compression screw, a spring fixing plate, a ratchet wheel and a turnkey gear. Ratchets of the ratchet wheel which are sheathed on the periphery of a crankshaft sleeve are meshed with the ratchets of a ratchet shift lever, the ratchet shift lever abuts against the shift lever compression screw, one end of the ratchet shift lever is movably fixed on a pin, and the other end is movably connected with the solenoid valve or a cylinder by the pin and the connection rod, and a spring is arranged between the spring fixing plate and the ratchet shift lever. The device increases the brake power by 3-5 folds by a lever principle, reduces machine tool noise, in particular realizes reliable braking of a large-tonnage rigid press, and the safety indexes conform to corresponding items of JB3350.

Description

1. Technical field: [0001] The invention relates to an externally dialed emergency braking device, which relates to the technical field of safety stop devices for presses and is applied to various rigid presses. 2. Background technology: [0002] At present, the rigid press uses the clutch to control the cam block through the pedal or the electromagnet to block the turn key tail handle, so that the press stops at the top dead center. In the case of an accident, it cannot be stopped in an emergency. Therefore, the rigid press Press safety issues: It has always been a topic of concern to people in the industry in my country. In order to ensure that the press can achieve safe production and avoid personal injury accidents, a variety of rigid press safety devices are designed in China. Due to the many parts involved, it must pass the first level. Therefore, the braking time is relatively long, and the effect of emergency braking is difficult to guarantee; for another example, alth...
