Working principle：The PLC controller 18 is a kind of electronic system of digital operation, specially in industrial settings
Using and design.It using the memory that can program, be used to execute storage logical operation and sequential control, timing,
The instruction with operations such as arithmetical operations is counted, and various types of by the input (I) and output (O) interface, control of number or simulation
The mechanical equipment or production process of type.The model of PLC controller 18 can choose grind magnificent UNO-2182, mitsubishi FX2N -48MRD and
Mitsubishi FX2N -64MR etc.；The multiple punching drill bit 4 is the same model or different models；Court on described two fixture blocks 8
Groove is equipped with to one end of driven wheel 7；Control panel is provided in the PLC controller 18.
When original state, two No.1 cylinders 6 are in contraction state, and two fixture blocks 8 are in the shape separated with driven wheel 7
State；Two hydraulic cylinders 11 are in elongation state, and hydraulic cylinder 11 makes movable plate 5 be located at the top of its stroke range, two movements
Plate 5 makes rotating bar 2 and fixed ring 3 thereon and punching drill bit 4 be respectively positioned on the top of its stroke range；Two No. two cylinders 15
In contraction state, No. two cylinders 15 make two clamping plates 14 be separated from each other a certain distance；Its in the multiple punching drill bit 4
In 4 No. two slot 13 of face of punching drill bit downwards center.
When work, staff will need the aluminium alloy extrusions of punching across two clamping plates 14, the aluminium alloy extrusions
On need that mark line can be drawn in advance at the position of punching；Staff makes the aluminium alloy extrusions from one of clamp clip again
16 lower section passes through, and the bending section 21 of 16 both ends of clamp clip setting is easier to enable aluminum alloy to profile to pass through, clamp clip 16 and branch
The multiple springs 20 being arranged between bar 17 can clamp the aluminium alloy extrusions positioned at 16 lower section of clamp clip, and make the aluminium alloy extrusions
More stable state is kept, and multiple springs 20, which are arranged, can make clamp clip 16 clamp the aluminium alloy extrusions of different-thickness, improve
The scope of application of the invention；Then the one end of the aluminium alloy extrusions is passed through from the lower section of clamp clip 16 move back again by staff
It moves and is located at No. two 13 centers of slot at the position for making to be decorated with mark line on the aluminium alloy extrusions one end to the top of No. two slots 13
Top and the underface for being located at a punching drill bit 4 downwards.
Then power supply of the invention is opened, PLC controller 18 first controls on each movable plate 5 according to the instruction being previously entered
Two No.1 cylinders 6 elongation, two No.1 cylinders 6 drive corresponding fixture block 8 close to the driven wheel 7 of 2 end of rotating bar, when two
After a No.1 cylinder 6 is elongated to maximum travel limit, two fixture blocks 8 also in turn clamp driven wheel 7, at this time the two of rotating bar 2
End is clamped by two fixture blocks 8；Then PLC controller 18 controls two No. two cylinders 15 elongations according still further to the instruction of input,
No. two cylinders 15 drive corresponding clamping plate 14 close to the aluminium alloy extrusions being located between two clamping plates 14, when two No. two cylinders 15
After being elongated to maximum travel limit, two clamping plates 14 will aluminium alloy extrusions clamping；Then PLC controller 18 is according still further to input
Instruction control two hydraulic cylinders 11 and shrink, two hydraulic cylinders 11 drive corresponding fixed block 24 to move down, 24 band of fixed block
It moves corresponding movable plate 5 to move down along No.1 slot 12, two movable plates 5 drive the rotating bar 2 being located therein downward in turn
Mobile, a punching drill bit 4 in rotating bar 2 downwards is then close and presses to the aluminium alloy extrusions between two clamping plates 14,
After two hydraulic cylinders 11 are retracted to maximum travel limit, the punching drill bit 4 in rotating bar 2 downwards is also moved with movable plate 5
The bottom of its stroke range is moved, the punching drill bit 4 namely work, and the punching drill bit are punched out to the aluminium alloy extrusions
One end when 4 punching after aluminium alloy extrusions is then extend into No. two slots 13.
After the completion of the punching drill bit 4 in rotating bar 2 downwards is to aluminium alloy extrusions punching, PLC controller 18 is pressed again
Instruction according to input controls two elongations of hydraulic cylinders 11, two hydraulic cylinders 11 and then drive movable plate 5 and rotating bar 2 and rotating bar
Punching drill bit 4 on 2 moves up, until two hydraulic cylinders 11 are elongated to maximum travel limit, i.e. movable plate 5 and rotating bar 2
Original state is returned to, PLC controller 18 controls No. two cylinders 15 again and shrinks, and No. two cylinders 15 drive clamping plate 14 and are located at two folders
Aluminium alloy extrusions between plate 14 separates, until No. two cylinders 15 are retracted to original state；Last PLC controller 18 controls one again
Number cylinder 6 is shunk, and No.1 cylinder 6 drives fixture block 8 to separate with corresponding driven wheel 7, until No.1 cylinder 6 is retracted to original state
When, the present invention completes a punch work on aluminium alloy extrusions at this time, when needing to another position on aluminium alloy extrusions
It sets when being punched out work, mark line is drawn at another place on the mobile aluminium alloy extrusions being located between two clamping plates 14 of staff
Behind position to the surface at No. two 13 centers of slot, above-mentioned work step is repeated.
When the punching drill bit 4 downwards in the fixed ring 3 of rotating bar 2 needs replacing or carries out to aluminium alloy extrusions
When rushing various sizes of hole, the rotary electric machine 10 on each movable plate 5 is controlled by the control panel being arranged in PLC controller 18
Rotate certain angle, and two rotary electric machines 10 rotate towards identical, rotary electric machine 10 drives driving wheel 9 by belt 23
Also certain angle is rotated, driving wheel 9 drives driven wheel 7 also to rotate certain angle, the driven wheel at 2 both ends of rotating bar in turn
Also rotating bar 2 is driven to rotate certain angle, multiple punchings in rotating bar 2 and then drive fixed ring 3 and fixed ring 3 when 7 rotation
Drill 4 also rotates certain angle, and makes after the drive rotation of rotating bar 2 of rotary electric machine 10 most lower in multiple punching drill bits 4
Side one is in a vertical state, and the punching drill bit 4 is downwards and the positive center towards No. two slots 13, at this time when multiple punchings
When 4 model difference of drill bit, the present invention can carry out aluminium alloy extrusions to rush various sizes of hole；When multiple 4 models of punching drill bit
When identical, then the present invention has replaced new punching drill bit 4, and staff can unclamp the punching for having worn out or damaging and bore
It is replaced, is safeguarded more convenient after collet 19 on first 4.
