Description
Technical field：
It is related to forging machine tool field the present invention relates to invent, more particularly to a kind of punching machine electromechanical overload is protected and drawn
Stretch device and method.
Background technology：
At present, in the market punching machine overload protection arrangement is mostly divided into two kinds, and one kind is breaker formula protector dress
Put, as shown in Fig. 2 including lid, connecting rod, latch segment, ball screw, screw, bulb gland, ball cup, protector, protector pad
The structures such as plate, slide body, clip module, striker plate, pointer, pressing plate, another kind is hydraulic pressure overload protective device, as shown in figure 3, bag
Connecting rod is included, ball screw, union (screwed)bonnet (UB, gland, screw, bulb gland, flat key, worm gear is sold, baffle ring, oil cylinder, bulb piston,
Hydraulic pressure oil meter, hole is sealed with rectangle, slide body, worm screw, the structure such as hydraulic power unit.It is mainly used in overload in the forcing press course of work
Protection, that is, a kind of relief arrangement when load is more than rated load 100% -110% when working.Simultaneously when forcing press occurred
After load, overload protective device rapidly can resume work state forcing press, and breaker formula protector is found in actual production
Device and hydraulic pressure overload protective device all have certain defect.There is slight overload metal protector not in breaker formula protector
Certain rupture, and lathe alarm free can be with normal work, and as forcing press long term overloading works, metal protector fatigue is strong
Degree increase, metal protector is deformed or even ruptures, and can take out the protector of breakage from slip front grid in theory
Changed, often occur to be pulled out during protector deformation is stuck in sliding block inner chamber in practice, end link and sliding block need to be dismantled,
So result in maintenance time it is long, laborious, influence equipment service efficiency.The hydraulic pressure overload protective that medium-and-large-sized punching machine is used
Often there is leakage not according to nominal pressure unloading in use in device, and reliability and stability are poor.Generally using warp
Test to be explored with test method and solve, the reason for cannot fundamentally finding off-load in advance well of losing time.Oil pipe, soldering oil
Case and seal are possible to because moment pressure is excessive or long-time is using there is oil leakage phenomenon, equal to lathe correction maintenance and maintenance
Affect.And the slide body built-in hydraulic cylinder structure of hydraulic pressure overload protective device is complicated, manufacture requires height, into
This is higher.
In addition, when the single, double point of open type, enclosed, 4 punching machines work, under dynamic action, connecting rod band movable slider
Body is descending, and the moment of upper/lower die closure completes the shaping such as punching press, extruding, die forging, without stretching or soft stretch function.Mould
Tool closure moment is likely to result in stamped workpieces and has that flash, workpiece surface roughness be poor, stretching is incomplete or because of crushing failure at high speed work
Part causes the qualification rate of workpiece to reduce, and it is very high to there is equipment investment cost according to servo-pressing machine, and hydraulic press production effect
The problems such as rate is relatively low.
The content of the invention：
The invention provides a kind of protection of punching machine electromechanical overload and stretching device and method, it is reasonable in design, tool
There are easy to operate, inexpensive unique structure, safe and reliable, high efficiency, maintenance and repair, environmental protection, realize soft stretch, extension
The advantages of punching machine and mold use life-span and raising forming quality of products, solve and asked present in prior art
Topic.
The present invention is for the solution technical scheme that is used of above-mentioned technical problem：
A kind of punching machine electromechanical overload protection and stretching device, including the press connecting rod being vertically arranged, in pressure

A motion bar being engaged with blind hole is provided with, motion bar is movably arranged in blind hole, between press connecting rod and guide post
Motion bar outside is arranged with butterfly spring, and press connecting rod is connected with guide post by some bolts being vertically arranged, bolt
Top is connected with press connecting bar screw-thread, and shank of bolt activity passes through guide post, the top of the guide post below press connecting rod
Travel switch is provided with, travel switch is connected with electrical overloads Protection control system；The bottom of guide post is spherical with what is be vertically arranged
The top of screw rod is connected, and the bulb of ball screw is connected with slide body.
Adjustable switch bracket is provided with the top of guide post, the travel switch is arranged on switch bracket.
A kind of punching machine electromechanical overload guard method, during forcing press works, press connecting rod drives to be slided
Block is moved up and down, and overload sets the compression travel of maximum nominal pressure beyond disk spring, and press connecting rod lower surface is moved
Dynamic to touch travel switch, travel switch sends a signal to electrical overloads Protection control system, and electrical overloads Protection control system is opened
The dynamic throw-out-of clutch for realizing forcing press, brake engagement, slide body stopping are descending, realize that punching machine electromechanical overload is protected
Shield.
A kind of punching machine drawing process, during forcing press works, press connecting rod drives slide body upper and lower
Back and forth movement, connects mold, and drive mold to move downward and lower mould closure stamped workpieces, pressure below slide body
More than disk spring setting stretching precompression, disk spring start compression, mold continue reinforcement slow down it is descending, realize punching press,
Extruding, die-forging forming stretching.
The present invention uses said structure, and no longer overload protection arrangement is arranged in slide body, carries out after long-term use
No longer need to remove sliding block equipment during maintenance and repair, maintenance and repair is easy to operate, the installation of device is simple, reliable, for manufacture
It is less demanding, the manufacturing cost of whole set equipment is reduced, situations such as be not in oil leak at work, will not be to the maintenance of lathe
Impacted with maintenance；In addition, can be realized during punching press is carried out using the press connecting rod that elastic pre-stress is designed
Soft stretch, the edge of work produced is smoothed, and surface is smooth, and the qualification rate of workpiece is higher.With unique structure, safety can
By, high efficiency, low cost, environmental protection, prolonged mechanical forcing press and mold use life-span and improve forming quality of products etc.
Advantage.
