[0002] At present, the rigid press uses the clutch to control the cam block through the electromagnet to block the tail handle of the rotary key, so that the press stops at the top dead center. When an accident occurs, it cannot stop in an emergency. Although there is an emergency braking device, due to the There are many other parts, and the braking force must be transmitted step by step. In addition, the key is forced to be off the key, and the stop stroke is too long, which makes it difficult to ensure the effect of

Embodiment Construction

[0006] Below in conjunction with accompanying drawing, the present invention will be further described;

[0007] See attached figure 1 , the whole device is located between the flywheel and one side of the bed, the mounting plate (12) is fixed with a garden pin (2-1), and the garden pin (2-1) is flexibly connected to the ratchet (2), and the ratchet (2) A spring (4) is arranged between the spring seat (5), and the lower end of the ratchet (2) is connected with the cylinder (1). Within the range of 135° of radian, the crankshaft (7) fixes the cover (8) into one body through the key (6), and a rotary key (10) is arranged between the flywheel cover (13) and the cover (8). Key shank is provided with in the groove of block (11) on ratchet (9), and ratchet (9) is installed on the crankshaft (7), and flywheel is housed outside flywheel cover (13).

[0008] See attached figure 1 , the press starts, the flywheel rotates, and the rotary key (10) is pulled by the spring of the rotary ...

Abstract

The invention discloses a ratchet typed braking device which comprises a structure including a cylinder, a round pin, a locating nail, a spring, a spring seat, a key, a crankshaft, a sleeve, a rotating key, a check block, a mounting panel and a flywheel sleeve. The mounting panel is fixed with the round pin, the spring seat and the locating nail; the round pin is movably connected with a pawl; the spring is arranged between the pawl and the spring seat; the lower end of the pawl is connected with an electromagnet or the cylinder; a spine wheel is emptily coated on the crankshaft. As the pitch of the spine teeth is short; the rotating key drawing is quick; the time of emergency braking is short and stable and reliable, when coupling with a photoelectric switch, the emergency braking can be promptly and effectively operated. The braking time is shorter than 30 percent of national related regulations; the happening of personal injury accidents is effectively prevented; and the life safety of people is practically protected.

Description

1. Technical field: [0001] The invention relates to a ratchet brake device, which relates to the technical field of brake devices for press machines, in particular to the technical field of brake devices for rigid press machines, and is applied to various punch machines. 2. Background technology: [0002] At present, the rigid press uses the clutch to control the cam block through the electromagnet to block the tail handle of the rotary key, so that the press stops at the top dead center. When an accident occurs, it cannot stop in an emergency. Although there is an emergency braking device, due to the There are many other parts, and the braking force must be transmitted step by step. In addition, the key is forced to be off the key, and the stop stroke is too long, which makes it difficult to ensure the effect of emergency braking. The manufacturing cost is relatively high and maintenance is difficult. Another example is the patented No. 01239060.7, the lever-embracing drum-...
