Description
Technical field
The present invention relates to a kind of hole punched device that is applied to the flat cold-rolled sheet machining production line, be specifically related to the driving laser welder weld seam of a kind of single cylinder sign hole punched device, the invention still further relates to a kind of hole-punching method.
Background technology
The every welding of cold rolling sour milling train group laser welder once just forms a weld seam, and hole punched device is at the circular hole of a φ 20mm of weld seam next door punching, and this circular hole is as the weld seam sign, in order to realize the function of soldering joint automatic tracking.During unit operation; the band steel in the process of walking; when weld seam during by the light on the unit-electric detection means; detection light will pass this circular hole and impinge upon on the receiver; receiver converts optical signal to the signal of telecommunication, and control system is sent the weld seam sign and reported to the police, and unit is run slowly in case the weld seam broken belt; guarantee safe operation, perhaps shut down bundling.
The hole punched device that generally adopts at present adopts " twin-tub driving " structure, and the equipment schematic diagram is seen accompanying drawing 1, accompanying drawing 2, and wherein the drift base is formed a whole by bottom inverted conical platform and top inversion " protruding " type cylinder, and there is an annular groove centre.The technical process brief introduction is as follows:
A, punch process: receive control system and send the punching instruction, the fluid cylinder pressure gets electric, its piston rod upwards walking stretches out, kinematic link clockwise rotates along axle, the walking downwards of drift base and drift suspends (as shown in Figure 1 position) to " preparation " position, cylinder gets electric, its piston rod is walked left to stretch out and is made U-shaped plug embedding matrix notch and will guarantee the bottom surface of U-shaped plug and the inverted conical body end face close contact (as shown in Figure 2) of drift base, then, drift base and drift go out a circular hole to continuing walking downwards from " preparation " position to " work " position to the band steel drift;
Here the effect of " U-shaped plug embeds the 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: with the reaction force that U-shaped plug bears and produces when blocking punching, guarantee device security.During punching, can produce a very strong reaction force to drift base and drift with steel, 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 the bottom surface of U-shaped plug and drift base inverted conical body end face close contact, could effectively bear and block this reaction force;
B, reseting procedure: receive control system and send reset instruction, the withdrawal of walking downwards of the piston rod of fluid cylinder pressure, kinematic link rotates counterclockwise along axle, drift base and drift upwards walking suspend to " preparation " position, the piston rod of cylinder is walked to the right to regain and is made U-shaped plug break away from the drift base, and drift base and drift continue upwards walking and get back to original position " wait " position from " preparation " position.Whole punching operation is finished.
There is following defective in existing hole punched device:
1, the installation site is narrow in addition for the many and complex structure of equipment, is unfavorable for the production of working continuously of quick-replaceable equipment and unit;
2, because " preparation " status requirement off-position of punching and reseting procedure is accurate, so installation accuracy is had relatively high expectations, otherwise the stuck fault of U-shaped plug machinery can appear, the inverted conical body end face that the bottom surface of U-shaped plug and drift base perhaps occur can not close contact, does not have to bear and block the effect that reaction force and protection equipment are not damaged;
3, be provided with " wait ", " preparation " and " work " 3 Position Control, the electrical control program is complicated, breaks down easily.
Summary of the invention
