Abstract
The invention relates to an automatic material ejection mechanism of a die forging press. The automatic material ejection mechanism mainly comprises a cycloidal pin gear speed reducer, a lead screw, a coupling band, a supporting seat, a bolt, a key, a support, a bearing, felt and a threaded sleeve. The cycloidal pin gear speed reducer and the lead screw are fixed through the coupling band and the key, the threaded sleeve is fixed to the lead screw in a matched mode, the lead screw is connected with the supporting seat through the bearing, one end of the supporting seat and the cycloidal pin gear speed reducer are fixed together through the bolt, the other end of the supporting seat and the support are fixed together, the lead screw is driven by the cycloidal pin gear speed reducer to rotate so that the threaded sleeve can be driven to do linear motion, and a forge piece is precisely and reliably ejected from a die by the threaded sleeve.
Description
Technical field
The invention belongs to forging equipment technical field, relate in particular to the automatic material jacking mechanism of drop press.
Background technology
The bottom knockout mechanism of drop press is the important component part of equipment, its effect is will forge after material die-forging forming at forging press, forging jack-up from mould, makes direct labor can be relatively easy to forging to pick up, workpiece is shifted out from mould, thereby realize the production of next forging.The bottom knockout mechanism of drop press is generally hydraulic-driven at present, because the number of strokes of forging press is per minute more than 10 times, the work of each run oil cylinder once, so just make the very fast of pressure oil circulation, oil temperature under the effect of pressure can rise, and system liquid pressing system does not arrange cooling device, causes system oil temperature to rise, viscosity degree declines, and causes fuel feeding undesired.In addition on the impulsive force reaction in forging and oil cylinder, cause system instantaneous pressure suddenly to rise, impact hydraulic system, damage pipe joint and fuel tank, cause leakage of oil.Finally cause hydraulic system pressure not enough or without phenomenons such as pressure, make ejector beam cisco unity malfunction, forging cannot jack-up, and forging cannot take out at short notice, and production can not normally be carried out, and forging reprocessed products increase, waste of manpower, financial resources and the energy.And Hydraulic Elements are expensive, change difficulty.
Summary of the invention
The automatic material jacking mechanism that the object of this invention is to provide a kind of drop press,, realizes forging jack-up from mould as driving accurately, reliably with cycloidal planetary gear speed reducer, and efficiency is high.
Technical scheme of the present invention is with coupling band and key, to fix between cycloidal planetary gear speed reducer and screw mandrel, swivel nut is fixed on screw mandrel, described screw mandrel is connected with supporting seat by bearing, supporting seat one end is fixed with bolt and cycloidal planetary gear speed reducer, one end and support are fixed, cycloidal planetary gear speed reducer drives screw mandrel to rotate, thus band movable snail sleeve moving linearly, swivel nut accurately, reliably forging jack-up from mould.
As preferably, the common location bearing of the shaft shoulder on screw mandrel and supporting seat, the screw mandrel resistance of motion is little.
Further, between screw mandrel and supporting seat, there is felt (8) interval, guarantee the cleaning of screw mandrel and forging, avoid greasy dirt seepage.
The present invention is by technical scheme above, can be accurately, realize forging jack-up from mould reliably, and efficiency is high, guarantees that production normally carries out, and forging quality is guaranteed.
Accompanying drawing explanation
Fig. 1 is the front view of invention;
1 cycloidal planetary gear speed reducer 2 coupling band 3 supporting seat 4 bolt 5 key 6 support 7 bearing 8 felt 9 screw mandrel 10 swivel nuts in figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated.
The invention provides a kind of automatic material jacking mechanism of drop press, as shown in Figure 1, mainly comprise cycloidal planetary gear speed reducer 1, screw mandrel 9, coupling band 2, supporting seat 3, bolt 4, key 5, support 6, bearing 7, felt 8, swivel nut 10,
Fixing with coupling band 2 and key 5 between described cycloidal planetary gear speed reducer 1 and screw mandrel 9, swivel nut 10 is fixed on screw mandrel 9, described screw mandrel 9 is connected with supporting seat 3 by bearing 7, supporting seat 3 one end are fixing with cycloidal planetary gear speed reducer 1 with bolt 4, one end and support 6 are fixing, cycloidal planetary gear speed reducer 1 drives screw mandrel 9 to rotate, thereby band movable snail sleeve 10 moving linearlies, swivel nut accurately, reliably forging jack-up from mould, the fixedly employing prior art of support 6 and drop press structure, here no longer statement.
During concrete enforcement, described in, the shaft shoulder on screw mandrel 9 and the common location bearing 7 of supporting seat 3, reduce the screw mandrel resistance of motion.Between screw mandrel 9 and supporting seat 3, there are felt 8 intervals, guarantee the cleaning of screw mandrel and forging, avoid greasy dirt seepage.
