Abstract
The utility model relates to a high-speed punching machine punching mechanism. A crank is connected between the frame and the upper die, and the crank is composed of an upper connecting rod and a lower connecting rod. The top of the cylinder rod of the hydraulic oil cylinder is connected with the crank dot of the upper connecting rod and the lower connecting rod. When the utility model is in one period, the crank is positioned on the middle point and acts the work on the punching two times. Compared with the structure of the eccentric wheel, the efficiency of the utility model can raise two times. The structure of the crank has the amplified action of the force, which relatively reduces the energy consumption and controls the plunger operation of the hydraulic cylinder and adjusts the punching speed and punching deepness.
Description
Technical field:
The utility model relates to press, particularly to the improvement of the punching mechanism of punch press.
Background technology:
The punching mechanism of existing punch press generally passes through transmission device by motor, drives flywheel and the eccentric wheel coaxial with it, and eccentric wheel is connected with upper trimming die by connecting rod, utilizes eccentric rotation, drives upper trimming die and pumps, and realizes the punch die operation.This traditional mechanism, one be reciprocating stroke can only punching out once, efficient is low, the 2nd, complex structure, the 3rd because the rotary inertia work done of flywheel, the upper trimming die impact endurance test shock is big; The too fast easy generation of opening speed exists towards part stress, and influence is towards the part quality; Rush in speed, opening speed, rushing in the degree of depth can not regulated at will.
Goal of the invention:
But the purpose of this utility model is a kind of simple in structure, one-period punching out twice of design, and the punch ram mechanism of the conveniently adjusted punching out degree of depth, punching out speed.
The elbow of being made up of last connecting rod and lower link between frame and the upper trimming die that turns that is characterised in that of the present utility model is connected, and the piston rod top of hydraulic jack and the elbow point of last connecting rod and lower link axle connect.
The punching mechanism that turns elbow formula punch press that the utility model adopts upper and lower strut to form, with oil cylinder elbow is put the application of force, when elbow point from initial point through mid point to far point, get back to the one-period of initial point through mid point from far point again, turn elbow and be in mid point punching out work done for twice, with respect to eccentric wheel structure, efficient can double; Knownly turn the amplification that the elbow structure has power, so can reduce energy consumption relatively; By the oil-feed speed of control oil cylinder, can regulate punching out speed; The oil-feed time and the oil mass of control oil cylinder, the stroke of adjustable fuel-economizing cylinder piston rod, such as being pulled during near mid point when elbow point, do not withdraw when at this moment upper trimming die reaches lowest depth, also promptly change the punching out degree of depth, in this manner one-period can only punching out once, but can satisfy the needs of special circumstances.
Description of drawings:
Accompanying drawing has provided the utility model example structure schematic diagram.
The specific embodiment:
With reference to accompanying drawing.Trunnion axis 2 is installed at frame 1 top, last connecting rod 3 upper end activities are placed in this axle, last connecting rod 3 lower ends and lower link 7 upper ends flexibly connect by axle 4, and axle 4 also flexibly connects with the piston rod top of oil cylinder 6 simultaneously, and lower link 7 lower ends flexibly connect by axle 8 and upper trimming die 10.By the effect of axle 8 and guide pillar 9, make and turn the up-and-down movement up and down that elbow point traverse motion changes upper trimming die 10 into.Dotted line has been represented to turn the elbow point and has been in mid point, far point location status among the figure.
Claims (1)
1, a kind of punching mechanism of high velocity ram machine, it is characterized in that the elbow of being made up of last connecting rod (3) and lower link (7) between frame (1) and the upper trimming die (10) that turns is connected, the piston rod top (5) of hydraulic jack (6) and the elbow point axle company of last connecting rod (3) with lower link (7).
