Description
Technical field
The present invention relates to a kind of hole punched device being applied to flat cold-rolled sheet machining production line, be specifically related to a kind of single cylinder-actuated type laser welder weld seam mark hole punched device, the invention still further relates to a kind of hole-punching method.
Background technology
Cold rolling sour rolling mill laser welder often welds once, and just form a weld seam, hole punched device rushes the circular hole of a φ 20mm on weld seam side, this circular hole as weld seam mark, in order to realize the function of soldering joint automatic tracking.During unit operation; band steel in the process of walking; when weld seam is by light-electric detection means on unit; detect light to shine on the receiver through this circular hole; receiver converts optical signal to the signal of telecommunication, and control system sends weld seam mark and reports to the police, and unit is run slowly in case weld seam broken belt; guarantee safe operation, or shut down bundling.
The hole punched device generally adopted at present adopts " twin-tub driving " structure, and equipment schematic diagram is shown in accompanying drawing 1, accompanying drawing 2, and wherein drift base is formed a whole by bottom inverted conical platform and top inversion " convex " type cylinder, and there is an annular groove centre.Technical process brief introduction is as follows:
A, punch process: receive control system and send punching instruction, fluid cylinder pressure obtains electric, its piston rod is upwards walked and is stretched out, kinematic link rotates clockwise along axle, drift base and drift walk downwards " preparation " position suspend (as shown in Figure 1 position), cylinder obtains electric, its piston rod is walked left to stretch out and is made U-shaped plug embed matrix notch and will guarantee the bottom surface of U-shaped plug and inverted conical body end face close contact (as shown in Figure 2) of drift base, then, drift base and drift are to continuing walking downwards from " preparation " position to " work " position, a circular hole is gone out to band steel drift,
Here the effect of " U-shaped plug embeds matrix notch and will guarantee the bottom surface of U-shaped plug and the inverted conical body end face close contact of drift base " is: the reaction force produced when bearing and block punching with U-shaped plug, guarantees device security.During punching, band steel can produce a very strong reaction force to drift base and drift, and this reaction force upwards conducts to the equipment such as kinematic link, axle and fluid cylinder pressure, in the course of time, can cause these device damage.When bottom surface and the drift base inverted conical body end face close contact of U-shaped plug, could effectively bear and block this reaction force;
B, reseting procedure: receive control system and send reset instruction, the piston rod of fluid cylinder pressure is walked downwards withdrawal, kinematic link rotates counterclockwise along axle, drift base and drift upwards walk " preparation " position suspend, the withdrawal of walking to the right of the piston rod of cylinder makes U-shaped plug depart from drift base, and drift base and drift continue from " preparation " position upwards to walk and get back to original position " wait " position.Whole punching operation completes.
There is following defect in existing hole punched device:
1, installation site is narrow in addition for the many and complex structure of equipment, is unfavorable for that quick-replaceable equipment and unit are worked continuously production;
2, " preparation " status requirement off-position due to punching and reseting procedure is accurate, therefore installation accuracy requires higher, otherwise there will be the stuck fault of U-shaped plug machinery, or occur that the inverted conical body end face of the bottom surface of U-shaped plug and drift base can not close contact, do not have the effect born and block reaction force and proterctive equipment and be not damaged;
3, be provided with " wait ", " preparation " and " work " 3 position controls, electrical control program is complicated, easily breaks down.
Summary of the invention
The object of the invention is to the weak point overcoming above-mentioned existing background technology, a kind of single cylinder-actuated type laser welder weld seam mark hole punched device is provided.
The present invention is achieved in that
A kind of single cylinder-actuated type laser welder weld seam mark hole punched device, comprise a drift, cylinder, it is characterized in that: described cylinder is connected hinge by cylinder piston rod with up/down swing arm and is connected, up/down swing arm connects hinge and is connected with upper swing arm and bottom swing arm respectively, the middle part of upper swing arm and a changeless upper swing arm chain connection of center position, the middle part of bottom swing arm and a center position bottom swing arm moving up and down chain connection, above upper swing arm, there is a upper branching holder, drift is connected with in bottom swing arm bottom.
In order to enable drift complete punching more accurately, there is a drift guide hole in drift arranged outside.
In the present invention, upper branching holder, upper swing arm and bottom swing arm, upper swing arm hinge, bottom swing arm hinge are connected hinge and are the good steel body structure of mechanical strength with up/down swing arm, can bear the impact of active force; And cylinder is owing to being arranged on the vertical direction of active force, does not directly bear impact firmly, receive and protect safely and reliably.
Present invention also offers a kind of hole-punching method, employ single cylinder-actuated type laser welder weld seam mark hole punched device disclosed by the invention, comprise the punching flow process of at least one punch process and a reseting procedure composition, specific as follows:
Punch process: control system sends punching instruction, the magnetic valve of cylinder must be established by cable and begin to start, cylinder piston rod stretches out from " wait " position level, upper swing arm and bottom swing arm are connected hinge around upper swing arm hinge with up/down swing arm respectively and rotate forward, changed to straight configuration by former state of cranking arm, bottom swing arm is in straight configuration change procedure, drive drift around bottom swing arm hinge rotate and along drift guide hole walk downwards to be positioned at below band steel carry out punching, until upper swing arm and bottom swing arm stretch arrival " work " position completely, at this moment go up swing arm and withstand upper branching holder, the upward reaction force that during punching, steel plate produces is absorbed by supporting base and offsets, complete punch process, then " work " position switch sends reset instruction to control system,
Reseting procedure: after receiving reset instruction, cylinder makes piston rod shrink from " work " position level, upper swing arm and bottom swing arm are connected hinge around upper swing arm hinge with up/down swing arm respectively and rotate backward, changed to state of cranking arm by " work " position straight configuration, lower swing arm straps is moved drift and is upwards lifted along drift guide hole, until upper swing arm and bottom swing arm turn back to original position " wait " position in the state of cranking arm, " wait " position switch sends cutoff command to control system, system shutdown, hole punched device completes a punching flow process and waits for next operation in " wait " position.
Single cylinder-actuated type laser welder weld seam mark hole punched device of the present invention and hole-punching method tool have the following advantages:
1) equipment is few, simple for structure, is convenient to carry out demolition, installation and maintenance in narrow location, is conducive to unit and works continuously production;
2) eliminate " preparation " position, too high requirement is not had to installation accuracy, there is not mechanical stuck point, reduce device damage and spare parts consumption;
3) only have " wait " and " work " 2 position controls, control program and electric wiring simplify, and fault is reduced.
