Abstract
The utility model discloses an outwards-dialing emergency braking device, which comprises an electromagnetic valve, a mounting plate, a connecting bar, a deflector rod pressing nail, a spring fixing plate, a ratchet wheel and a key rotating shift, wherein, a ratchet wheel ratchet sleeved on the periphery of a crank sleeve is meshed with a ratchet on a ratchet deflector rod which is pressed against the deflector rod pressing nail, one end of the ratchet deflector rod is adjustably fixed on a pin shaft, the other end is adjustably connected with the electromagnetic valve or a cylinder by the pin shaft and the connecting bar, a spring is arranged between the spring fixing plate and the ratchet deflector rod. The theory of the lever is adopted to increase the brake resistance by 3-5 times and to reduce the noise of a machine tool; the reliable brake of a large-tonnage rigidity pressing machine can be realized; the safety index accords with concerned clause of JB3350.
Description
One, technical field:
A kind of push-out type emergency braking device of the utility model, what relate to is forcing press safety stop device technical field, is applied to various rigid press.
Two, background technology:
At present, rigid press utilizes clutch, by foot-operated mode or magnet control cam dog, block the turn key caudal peduncle, forcing press is stopped at top dead-centre, under situation about meeting accident, can't stop in emergency, therefore, rigid press safety problem: always be the problem that China insider is concerned about, for guaranteeing that the pressure function reaches safety in production and avoids personal injury accident, domestic design that multiple rigid press safety device is arranged, because other part that involves is more, must transmit by the one-level one-level, therefore, cause braking time longer relatively, the effect of brake hard is difficult to guarantee; And for example, the brake apparatus that has is though structure is reasonable, good braking effect, but because the brake force that produces is little, can only be applicable to the rigid press of little tonnage, exist greater than being difficult to realize brake hard or the unfavorable defective of braking effect on the rigid press more than 40 tons.
Three, summary of the invention:
The purpose of this utility model is: the existing rigid press emergency safety of existing market stop device is improved, thereby it is longer to overcome the stop time, defectives such as braking effect is undesirable design a kind of more practical, safe and reliable a kind of push-out type emergency braking device.Its technology is to realize like this, comprise magnetic valve, installing plate, connecting rod, driving lever is pressed nail, spring dead plate, ratchet, the turn key retaining is in interior structure, it is characterized in that: the ratchet that sky is enclosed within the ratchet of flywheel sleeve periphery is meshed with ratchet on the ratchet driving lever, ratchet driving lever and driving lever press nail to offset, ratchet driving lever one end is fixed on the installing plate by bearing pin is active, the other end is by the active magnetic valve that is connected of bearing pin and connecting rod, be provided with spring between spring dead plate and the ratchet driving lever, the shape of ratchet driving lever can be the structure of crooked shape and straight-bar shape, what be connected with connecting rod one end can be magnetic valve, also can be cylinder or hydraulic cylinder.The positive effect of implementing after this technology is: overcome above-mentioned defective, utilized the principle of lever, increased by 3～5 times of stopping powers, lowered machine noise, realized the reliable stop of large-tonnage rigid press especially, safety index meets the relevant clause of JB3350.
Four, description of drawings:
Fig. 1 is the main TV structure schematic diagram of a kind of push-out type emergency braking device of the utility model;
Wherein: 1-spring, 2-spring dead plate, 3-magnetic valve, 4-connecting rod, 5-ratchet driving lever, 6-driving lever are pressed nail, 7-bent axle, 8-bent axle cover, 9-ratchet, 10-turn key, 11-turn key retaining, 12-key, 13-flywheel sleeve, 14-installing plate, 15-bearing pin,
Five, the specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
See accompanying drawing 1, a kind of installing plate of push-out type emergency braking device (14) is fixed on the lathe bed between flywheel and the lathe bed, ratchet driving lever (5) one ends are fixed on the installing plate (14) by bearing pin (15) is active, magnetic valve (3) is fixed on the installing plate (14), sky is enclosed within the ratchet of ratchet (9) of bent axle cover (13) periphery and the ratchet engagement of ratchet driving lever (5), ratchet driving lever (5) presses nail (6) to offset in the ratchet upper end of ratchet driving lever (5) with driving lever, ratchet driving lever (5) other end connects connecting rod (4) by bearing pin, connecting rod (4) other end connects magnetic valve (3), be fixed between spring dead plate (2) on the installing plate (14) and the ratchet driving lever (5) and be provided with spring (1), turn key (10) shank of being located between flywheel sleeve (13) and the bent axle cover (8) buckles into turn key retaining (11), and flywheel sleeve (13) is fixed as one with flywheel.
See accompanying drawing 1; start power supply; rigid press is started working; the flywheel rotation; magnetic valve (1); magnetic valve (1) pulling connecting rod (4) moves downward; the ratchet driving lever (5) that is connected with connecting rod (4) is moved downward for the center along bearing pin (15); drive ratchet driving lever (5) ratchet to inner rotary; ratchet driving lever (5) breaks away from driving lever and presses nail (6); the ratchet that breaks away from ratchet (9); at this moment; original turn key spring pulling turn key (10) is moved an angle; enter the operating position; bent axle cover (13) meshes with the flywheel of forcing press; bent axle cover (13) drives bent axle (7) along with the flywheel rotation by key (12); the normal work of beginning; when in case the light curtain sends state of emergency signal; the power supply of flywheel is cut off; implement the rotation of inertia ground, at this moment, magnetic valve (3) dead electricity; lose magnetive attraction; the ratchet driving lever (5) of ining succession is lost power simultaneously, and ratchet driving lever (4) is under the effect of the spring force of spring (1), and the ratchet of ratchet driving lever (5) is buckled in the ratchet of ratchet (9); stoped the rotation of ratchet (9); turn key retaining (11) on the ratchet (9) overcomes the spring force of original turn key spring, forces turn key (10) to reverse an angle, breaks away from the operating position between flywheel and the bent axle cover (13); flywheel idle running; bent axle (7) is checked by the brake gear of forcing press, and bent axle (7) quits work, emergency shutdown on the optional position of down stroke; thereby avoided the generation of personal injury accident, protected operator's life security effectively.
According to the actual conditions of rigid press, the shape of ratchet driving lever can be the structure of crooked shape and straight-bar shape.
