Abstract

The utility model discloses a ratchet wheel emergency braking device, comprises a rotating key, a spring, a crank shaft, a rotating key slot, a compression spring, an adjusting screw rod, a guide rod, a push-pull rod, an electromagnetic valve, a bearing holder, a benchmark plate, a guide plate, a retaining ratchet and a ratchet wheel. Wherein, the braking device is arranged on the crank shaft and fixed on a punch frame through the benchmark plate. The electromagnetic valve is positioned on the bearing holder is connected with the retaining ratchet through the push-pull rod. The retaining ratchet meshes with the ratchet wheel. Thus, the utility model has advantages of large braking force, wide applicable scope and directly application to large and small-sized punch and can realize high-quality emergency braking and tangibly protect operators' personal safety.

Description

A kind of ratchet-type emergency braking apparatus

One, technical field:

A kind of ratchet-type emergency braking apparatus of the utility model, 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 this utility model is for overcoming above-mentioned defective, adopting the ratchet means of retention, a kind of ratchet-type emergency braking apparatus of design.Its technology is achieved in that and comprises turn key, spring, bent axle, the turn key groove, the compression spring, adjusting screw(rod), guide rod, pull bar, magnetic valve, supporting base, datum plate, guide plate, the stop ratchet, ratchet 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 the stop ratchet by pull bar, stop ratchet and ratchet engaged, hook tooth is located in 180 ° of scopes of ratchet periphery, ratchet is provided with the turn key groove, ratchet is active to be enclosed within on the bent axle, also can establish bearing and positioning sleeve between ratchet and bent axle.The positive effect of implementing after this technology is: the brake force of generation is big, and is applied widely, can be directly used in the punch press of large and small tonnage, realizes brake hard, and good braking effect has been protected operator's personal safety conscientiously.

Four, description of drawings:

Fig. 1 is the structural representation of a kind of ratchet-type emergency braking apparatus of the utility model;

Wherein, 1-turn key, 2-spring, 3-bent axle, 4-turn key groove, 5-compression spring, 6-adjusting screw(rod), 7-guide rod, 8-pull bar, 9-magnetic valve, 10-supporting base, 11-datum plate, 12-guide plate, 13-stop ratchet, 14-ratchet

Five, the specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

See accompanying drawing 1, described ratchet-type emergency braking apparatus is located at bent axle (3) and goes up and be fixed on the lathe bed by datum plate (11), the supporting base (10) that is fixed on datum plate (11) is fixed with magnetic valve (9), magnetic valve (9) connects stop ratchet (13) by the pull bar (8) that passes guide plate (12), be connected and adjustable range by adjusting screw(rod) (6) between guide plate (12) and the stop ratchet (13), compression spring (5) between guide plate (12) and the stop ratchet (13) is enclosed within outside the adjusting screw(rod) (6), guide rod (7) one ends are fixed on the stop ratchet (13), the active guide plate (12) that passes of the other end, guide plate (12) is fixed on the datum plate (11), the active sky of ratchet (14) is enclosed within on the bent axle (3), and the key lever of the turn key (1) between bent axle (3) and the flywheel is limited in the turn key groove (4) on the ratchet (14).

See accompanying drawing 1, the punch press electric motor starting, flywheel (3) idle running, magnetic valve (9) must be electric, will draw in the pull bar (8), and stop ratchet (13) is enclosed within the last ratchet (14) of bent axle (3) with sky to be separated, and turn key (1) enters between bent axle (3) and the flywheel, realizes operate as normal; When meeting accident, photoelectric sensor obtains signal, cut off the electricity supply, magnetic valve (15) dead electricity, adjusting screw(rod) (6) is gone up compression spring (5) and is forced stop ratchet (13) to press down, and buckles into the ratchet in 180 ° of scopes of ratchet (14) periphery, at this moment, the turn key handle that is located in the turn key groove (4) on the ratchet (14) is moving by strong spline, turn key (1) overcomes the resistance of extension spring, breaks away to be connected flywheel idle running between bent axle (3) and the flywheel, bent axle (3) is lost power, brake gear by forcing press is checked, and prevents bent axle (3) descending, realizes stopping in emergency under the state of emergency, avoid the generation of personal injury accident, realized accident-free safety in production.

According to design, ratchet (14) is active to be enclosed within on the bent axle (3), also can establish bearing and positioning sleeve between ratchet (14) and bent axle.
