Abstract

The invention discloses a clamp urgent brake device, which comprises, a drum, a reference plate, a clamp, a clamp axle, a electromagnetic valve, a spring, a adjusting bolt, a pin, a pushing rod, a bearing base, a guide plate, a key pin, and a rotational key. Wherein, said brake device is arranged on the bent shaft and fixed on the bed via reference plate; the electromagnetic valve is fixed on the bearing base and via pushing rod to connect the guide plate; the guide plate is clamped into the end of clamp; and the clamp via clamp axle is movably mounted on two sides of drum. The invention has larger braking force, wider application, and it can be directly used in larger and smaller punch bed, with significant social and economic benefits.

Description

Clamp-tooth type emergency brake device

One, technical field:

Clamp-tooth type emergency brake device of the present invention, what relate to is forcing press braking device technique field, particularly rigid pressure machine braking device technical field is applied to all kinds of punch presses.

Two, background technology:

At present, rigid press utilizes clutch, by the magnet control cam dog, block the turn key caudal peduncle, forcing press is stopped at top dead-centre, when something unexpected happened, can't stop in emergency, though emergency braking apparatus is arranged,, must transmit brake force by the one-level level because other part that involves is more, the time of brake hard is longer relatively, add and force turn key to take off key, the stop stroke is long, is difficult to guarantee the effect of brake hard, and manufacturing cost is higher relatively, maintenance difficult, and for example existing a lot of emergency braking apparatus are though structure is reasonable, good braking effect, because the brake force that produces is little, can only be applicable to the punch press of little tonnage, ubiquity the defective that is difficult to realize brake hard or braking effect difference on greater than punch press more than 40 tons.

Three, summary of the invention:

The purpose of clamp-tooth type emergency brake device of the present invention is to overcome above-mentioned defective, utilizes lever principle to design a kind of caliper brake device.Its technology is achieved in that and comprises an armful drum, datum plate, clamp, the clamp axle, magnetic valve, the compression spring, adjusting screw(rod), pin, pull bar, supporting base, guide plate, key pin, turn key is in interior structure, it is characterized in that: described brake apparatus is located on the bent axle and by datum plate and is fixed on the lathe bed, magnetic valve fixing on the supporting base connects guide plate by pull bar, guide plate buckles into the clamp pommel, clamp is embraced the drum both sides by the clamp axle with active being fixed on of clamp, grip finger is provided with the clamp tooth, embrace the drum both ends of the surface and be provided with the teeth groove that matches with the clamp tooth, embracing the drum both ends of the surface can be the distribution of garden week or distribute in 135 ° of descending scopes of ram with the teeth groove that the clamp tooth matches, clamp shank inboard is provided with spring, clamp handle one side is provided with adjusting screw(rod), embrace drum one place and have turn key handle groove, the clamp (9) that adapts to different structures, the hole that can adopt guide plate (13) to stretch into the clamp handle has the structure of gradient, also can adopt cam mechanism to substitute guide plate (13) structure.

The positive effect of implementing after this technology is: the brake force of generation is big; applied widely; can be directly used in the punch press of large and small tonnage; realize brake hard; good braking effect; manufacturing cost is cheap relatively, has protected operator's personal safety conscientiously, and consequent economic benefit and social benefit are obvious.

Four, description of drawings:

Fig. 1 is the structural representation of clamp-tooth type emergency brake device of the present invention;

Wherein, 1-lathe bed, 2-ram, 3-flywheel, 4-turn key handle groove, 5-turn key, 6-embrace drum, 7-flywheel key, 8-key pin, 9-clamp, 10-fixed support, 11-adjusting screw(rod), 12-spring, 13-guide plate, 14-pull bar, 15-magnetic valve, 16-supporting base, 17-datum plate, 18-brake, 19-clamp axle, 20-bent axle;

Five, the specific embodiment:

Below in conjunction with accompanying drawing clamp-tooth type emergency brake device of the present invention is further described:

See accompanying drawing 1, described clamp-tooth type emergency brake device is located at bent axle (20) and goes up and be fixed on the lathe bed (1) by datum plate (11), supporting base (16) is gone up fixing magnetic valve (15) and is connected guide plate (13) by pull bar (14), guide plate (13) buckles into clamp (9) pommel that has gradient, clamp (9) upward and with jaw is located at armful drum (6) both sides by clamp axle (19) with the active fixed support (10) that is fixed on of clamp (9), clamp (9) jaw is provided with the clamp tooth, embrace drum (6) both ends of the surface and be provided with the teeth groove that matches with the clamp tooth, it is fixing by key pin (8) and bent axle (20) to embrace drum (6), embrace drum (6) and have turn key handle groove (4), clamp (9) pommel inboard is provided with spring (12), and clamp (9) pommel one side is provided with adjusting screw(rod) (11).

See accompanying drawing 1, the punch press electric motor starting, flywheel (3) idle running, magnetic valve (15), pull bar (14) is extrapolated, promote guide plate (13), clamp (9) pommel that will have gradient inwardly shrinks, and compression spring (12) is opened clamp (9) jaw, clamp (9) jaw opens, break away from and embrace drum (6), be located at an armful drum (6) and with turn key (5) extension spring turn key (5) drawn in the operating position, flywheel (3) is connected with bent axle (20) by flywheel sleeve, pin (7), make upper and lower the moving of ram (2) of punch press, realize operate as normal; When meeting accident, photoelectric sensor obtains signal, cut off the electricity supply, magnetic valve (15) dead electricity, after being drawn back, guide plate (13) withdraws from clamp (9) pommel that has gradient, the compressed spring of clamp (9) pommel (12) recovers elasticity, and clamp (9) pommel opens, and is provided with the jaw of clamp tooth relatively, clamp, clamp armful drum (6) both ends of the surface and be provided with the teeth groove that matches with the clamp tooth, stop operating, stop bent axle (20) rotation by embracing drum (6), meanwhile, embrace drum (6) and stop the active turn key (5) that snaps in the breach of embracing drum (6) to overcome the resistance of extension spring, between flywheel sleeve (15) and bent axle (20), break away from flywheel (3) idle running, the brake that adds lathe itself cooperates, realize stopping in emergency under the state of emergency, avoided the generation of personal injury accident, realize the zero defects safety in production.

For the clamp (9) that adapts to different structures, the hole that can adopt guide plate (13) to stretch into the clamp handle has the structure of gradient, also can adopt cam mechanism to substitute guide plate (13).
