Abstract
The invention relates to an automatic intermittent feeding mechanism of a punching machine. The automatic intermittent feeding mechanism comprises a punching machine worktable, wherein the punching machine worktable is provided with a bar conveying groove, the punching machine worktable is also provided with an upper roller and a lower roller for conveying a bar, the lower roller is concentrically provided with a one-way clutch, the one-way clutch is fixedly connected with one end of a connecting rod, and the other end of the connecting rod is fixed on an eccentric wheel for driving a punching machine punch head. The connecting rod is installed on the eccentric wheel, the connecting rod is driven by the rotation of the eccentric wheel to move, the other end of the connecting rod is connected to the one-way clutch, and the lower roller is driven by the one-way clutch to rotate, so that the bar is driven by the lower roller to move, and the automatic feeding is realized. Moreover, the one-way clutch only drives the lower roller to rotate intermittently in one direction, so that the bar is driven to be automatically and intermittently fed. The punching machine punch head and the connecting rod share one eccentric wheel, thus the punching intermittence of the punch head can be adequately utilized to feed the bar, the power of the punching machine is also adequately utilized, and a purpose for automatically and intermittently feeding can be realized.
Description
Technical field
The present invention relates to a kind of punching and edge-cutting mechanism, be specifically related to a kind of punch press interval-automatic feed mechanism.
Background technology
In cold stamping production process, punch die or pressing equipment adopt various mechanical device, replace manually completing punching production, be called punching production mechanization and automation.At present, punching automatic feeder structure has a variety of mode to realize.Wherein can be divided into following several large class: (1) numerical-control feed mechanism.This feed mechanism, by the control of numerical control, can realize multi-faceted feeding, can realize the feeding stroke of multiple feeding form and complexity.(2) electric feed mechanism.This feed mechanism is the realization being carried out feeding function by extra power source.(3) mechanical feed mechanism.Be the power by forcing press itself, by the power moved up and down of patrix, also by the power of rotating shaft, can realize the function of feeding.In a stamping press circulation, from feeding, starting, stroke of a press operation, this four processes of inloading part, the time of a press ram stroke, only account for 10 % ~ 25 % of a cycle time for working, the forcing press dry run time accounts for 90% ~ 75%, relevant with the qualification of stamping press classification, mould structure, stamping material situation, operative.Particularly when suitability for industrialized production, artificial loading can delay the efficiency of production, and the time not having Appropriate application forcing press to dally carries out automatic charging operation.
Summary of the invention
The object of the present invention is to provide a kind of punch press interval-automatic feed mechanism, the time that forcing press can be utilized to dally and power, realize the automatic transport of material, reaches the requirement of automatic charging.
For achieving the above object, technical scheme of the present invention is: punch press interval-automatic feed mechanism, comprise work bench of punch press, described work bench of punch press is provided with material strip delivery chute, described work bench of punch press is also provided with upper roll wheel and the lower roll wheel of conveying material strip, lower roll wheel is provided with one heart an one-way clutch, one-way clutch secures one end of connecting rod, the other end of connecting rod is fixed on the eccentric wheel of driving punch press drift.
When adopting technique scheme, owing to having installed a connecting rod on eccentric wheel, drive link motion by eccentric rotation, the other end of connecting rod is connected on one-way clutch, drive lower roll wheel to rotate by one-way clutch, thus drive material strip motion by lower roll wheel, realize self-feeding.Moreover one-way clutch can only drive the unidirectional intermittent rotary of lower roll wheel, thus drive the feeding of material strip automatic backlash.Because punch press drift and connecting rod share an eccentric wheel, feeding is carried out in the gap like this with regard to taking full advantage of punch, and takes full advantage of the power of punch press self, reaches the object of automatic backlash feeding.
Further, described upper roll wheel is arranged on work bench of punch press by stage clip, described work bench of punch press is arranged the fulcrum of a lever, and the two ends of lever are separately fixed on upper roll wheel and punch press drift.Above-mentioned setting before punching press starts, can be lifted by means of lever harrow upper roll wheel, and the billot be pressed between two running rollers is unclamped, and like this, can avoid the billot when punch press punch because of the extruding of running roller and produce tension force.
Further, described punch press drift be positioned at eccentric immediately below, described punch press drift and eccentric wheel form slider-crank mechanism.
Further, described upper roll wheel is identical with the diameter of lower roll wheel.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of punch press interval-automatic feed mechanism embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, punch press interval-automatic feed mechanism of the present invention, what mainly play feeding function is upper roll wheel 1 and lower roll wheel 2, is provided with placement billot on the table between two running rollers.Workbench is offered specially a groove, for contacting of upper roll wheel 1 and lower roll wheel 2 and billot.Lower roll wheel 2 is provided with one heart an one-way clutch 5, one-way clutch 5 secures one end of connecting rod 8, the other end of connecting rod 8 is fixed on eccentric wheel 7, and eccentric wheel 7 is driven by machine power.Immediately below eccentric wheel 7, bias is connected to a drift 4, makes drift 4 and eccentric wheel 7 form slider-crank mechanism, drift 4 can be driven to slide up and down at vertical guide rail by eccentric wheel 7, carry out stamping-out to billot.Moreover by the rotation of eccentric wheel 7, connecting rod 8 drives lower roller shaft 2 to rotate by one-way clutch 5, due to the effect of one-way clutch 5, lower roll wheel 2 can only be sent to billot off and on according to certain speed toward drift direction, and can not feeding be rotated backward.
In addition, as optimal design, upper roll wheel 1 can be installed on the table by stage clip 6, and arrange the fulcrum of a lever 3 on the table, the two ends of lever 3 are separately fixed on upper roll wheel 1 and drift 4.Before punching press starts, by means of lever 3, upper roll wheel 1 is lifted, the billot be pressed between two running rollers is unclamped, like this, the billot when drift 4 punching press can be avoided because of the extruding of running roller and produce tension force.
Owing to having installed a connecting rod 8 on eccentric wheel 7, moved by the rotation drivening rod 8 of eccentric wheel 7, the other end of connecting rod 8 is connected on one-way clutch 5, drives lower roll wheel 2 to rotate by one-way clutch 5, thus drive material strip to move by lower roll wheel 2, realize self-feeding.Moreover one-way clutch 5 can only drive the unidirectional intermittent rotary of lower roll wheel 2, thus drive the feeding of material strip automatic backlash.Because drift 4 and connecting rod 8 share an eccentric wheel 7, feeding is carried out in the gap like this with regard to taking full advantage of drift 4 punching press, and takes full advantage of the power of punch press self, reaches the object of automatic backlash feeding.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
