Abstract
The utility model provides a rotary type emergency braking device taking a shaft pin as a center and a pitch as a radius. The rotary type emergency braking device structurally comprises an electromagnet, a mounting board, a shift lever press nail, a spring fixing plate, ratchet wheels, a shaft pin and a key-turning gear, wherein the ratchet wheel loosely sleeved at the periphery of a flywheel sleeve is meshed with ratchets on a ratchet shift lever; a set screw is arranged at one end of the key-turning gear and used for fixing a turn key in the key-turning gear; two ratchets combined with the ratchet shift lever are arranged on one side of the ratchet shift lever; and the ratchets on the ratchet shift lever are triangular or quadrilateral and effectively ensure the time and the effect of emergency braking, so that the braking is reliable and the double insurance is realized, personal injury accident is effectively avoided, and the safety index is higher than that stipulated by the IB3350 relevant terms.
Description
Technical field
The utility model is a kind of to be that center, tooth pitch are the rotary emergency braking apparatus of radius with the pivot pin, and what relate to is forcing press safety stop device technical field, is applied to various forcing presses.
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 brake apparatus that has, rational in infrastructure, good braking effect, but, directly influenced braking time because caudal peduncle is unfixing, the shortage synchronized reserve ratchet that has is difficult to reach brake hard when the sour jujube of work damages.
Summary of the invention
The purpose of this utility model is existing lever-type rigid press emergency braking apparatus is improved, synchronized reserve ratchet and fixing caudal peduncle are set, thus realize more practical more reliable a kind of be that center, tooth pitch are the rotary emergency braking apparatus of radius with the pivot pin.Its technology is that sample is realized: comprise the structure that electromagnet, installing plate, driving lever press nail, spring dead plate, ratchet, pivot pin, turn key to keep off, it is characterized in that: sky is enclosed within the ratchet of flywheel sleeve periphery and is meshed with ratchet on the ratchet driving lever, turn key keeps off an end and is provided with holding screw fixing turn key in turn key retaining, ratchet driving lever one side is provided with two ratchets and ratchet driving lever disjunctor, and the shape of the ratchet on the ratchet driving lever is triangle or quadrangle.The positive effect of implementing after this technology is: overcome above-mentioned defective, guaranteed the time of brake hard and the effect of brake hard effectively, braking is reliable, realizes double insurance, thereby prevent the generation of personal injury accident effectively, safety index is higher than the relevant clause of JB3350.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Wherein, 1-spring, 2-spring dead plate, 3-magnetic valve, 4-connecting rod, 5-ratchet driving lever, 5-1-ratchet, 6-driving lever are pressed nail, 7-bent axle, 8, ratchet, 9-ratchet, 10-turn key, 11-turn key retaining, 11-1 holding screw, 12-key, 13-flywheel sleeve, 14-installing plate, 15-bearing pin;
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
See accompanying drawing 1, installing plate 14 is fixed on the lathe bed between flywheel and the lathe bed, ratchet driving lever 5 one ends are by pin bearing 15 active being fixed on the installing plate 14, and magnetic valve 3 is fixed on the installing plate 14, and a side of ratchet driving lever 5 is provided with two ratchet 5-1 with ratchet driving lever 5 disjunctors; Sky is enclosed within ratchet and the engagement of the ratchet 5-1 on the ratchet driving lever 5 that bent axle overlaps the ratchet 9 of 13 peripheries, ratchet driving lever 5 presses nail 6 to offset in ratchet 5-1 upper end with driving lever, ratchet driving lever 5 other ends connect connecting rod 4 by bearing pin, the other end of connecting rod 4 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 shanks of being located between flywheel sleeve 13 and the bent axle cover 8 buckle into turn key retaining 11, one end of turn key retaining 11 is provided with holding screw 11-1 and fixedly buckles into the interior turn key 10 of turn key retaining, wheel cover 13 is fixed as one with flywheel, with pivot pin 15 is the center, distance is a radius between pivot pin 15 and the ratchet 5-1, at 150mm.
See accompanying drawing 1, start power supply, forcing press is started working, the flywheel rotation, magnetic valve 3 gets electric, and magnetic valve 3 pulling connecting rods 4 move downward, the ratchet driving lever 5 that connecting rod 4 is connected rotates for the center along bearing pin 15, the ratchet 5-1 of drive and ratchet driving lever 5 disjunctors is to inner rotary, and 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, and bent axle cover 13 drives bent axle 7 along with the flywheel rotation by key 12, begins operate as normal; 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, the magnetic valve dead electricity, lose magnetive attraction, the ratchet driving lever 5 of ining succession is lost power simultaneously, and ratchet driving lever 5 is buckled in the ratchet of ratchet 9 with the ratchet 5-1 of ratchet driving lever 5 disjunctors under the spring force effect of spring 1, 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, make flywheel idle running, bent axle 7 is checked by the brake gear of forcing press, and bent axle 7 quits work, and stops in emergency in the optional position of down stroke, thereby avoided the generation of personal injury accident, protected operator's life security with producing effect; Moreover, if first ratchet of ratchet 5-1 is stressed excessive and fracture, second of ratchet 5-1 will work on, and be buckled in the ratchet of ratchet 9, stoped the rotation of ratchet 9 equally, 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, make flywheel idle running, bent axle 7 is checked by the car device that kills of forcing press, and bent axle 7 quits work, and realizes the function of double insurance.
