Abstract

The utility model discloses an energy storage type ejection impact hammer improved on the basis of existing shearing and punching equipment. A center shaft (18), an eccentric wheel (11) and a connecting rod (9) are driven by a speed reducer output shaft (15) through a clutch (16) so that a piston (8) can be pulled and a spring (2) can be compressed. After the eccentric wheel arrives at an upper dead point, control over a hammer body (4) is eliminated through one-way action of the clutch, the hammer body (4) becomes a free body and ejected through the spring and compressed air to beat a base (5), energy is released instantly, impact force is acquired through ejection, striking force can be increased by a plurality of times through kinetic energy of mass acceleration, and accordingly the size becomes very small, manufacturing cost becomes very low, energy consumption is reduced, and only ten percent of energy is consumed.

Description

Energy storage type launches jump bit

Technical field

The present invention relates to a kind of jump bit, is the modified of existing shearing, pressing equipment, for the jump bit that launches of the cutting out of metal material, shaping and rock drilling, rubble (cement).

Background technology

The energy storage of current punch press, plate shearing machine, cutting machine all adopts flywheel, its volume is large, energy storage is few, the main extruding force of leaning on is cut firmly, crank circles and only has half cycle to do manual work, the energy consumption of backhaul is a kind of waste in vain, the active force of slow pushing-type is very limited, so its volume will be done very greatly, cost is very high, energy consumption is very surprising.

Summary of the invention

The above-mentioned defect that prior art is existed, the present invention aims to provide that a kind of ability is stronger, volume is less, cost is lower, energy consumption energy storage type still less launches jump bit.

To achieve these goals, the present invention has adopted following technical scheme: it drives connecting rod of eccentric wheel to pull piston compression spring and air with the driving force after slowing down through clutch, eccentric wheel arrives after top dead center, the single effect of clutch makes tup lose constraint to become free body and by spring and compressed air, launched to hit and account for seat, abrupt release energy; In energy storage storehouse, comprise be equipped with spring and eccentric wheel be contained on central shaft by bearings, connecting rod one end with eccentric shaft be contained on eccentric wheel, the other end with link pin be contained on tup, tup is contained on piston, account for seat and dead knife is contained on pier shell, central shaft and axle sleeve are fixed together with flat key, the other end of axle sleeve and the outer ring of clutch with flat key be fixed together, the inner ring of clutch with flat key and reducer output shaft be fixed together, energy storage storehouse and pier shell be fitted together.

The clutch of clutch is unidirectional freewheel clutch, or with shift fork, ratchet, the in-built spring in energy storage storehouse has at least one or more, one end of piston is that the compressed air other end is that vacuum, central shaft and eccentric effect are to become reciprocating motion rotatablely moving, except eccentric wheel or with bent axle, cam.

Compared with prior art, the present invention, owing to having adopted technique scheme, has made spring and compressed-air energy storage into by flywheel, and savings ability strengthens, by the half cycle of crank, do manual work and made all-round workmanship into, there is no backhaul energy consumption, by extrusion type hard at a slow speed, cut and made into free body and launch, the kinetic energy of mass acceleration can make to hit active force increases several times, thereby volume energy significantly dwindles, cost reduces, and the more important thing is that energy consumption falls sharply, and only has common 1/10.
