Description
Technical field：
The present invention relates to mechanical press technical fields, and in particular to mechanical press brake pads intelligent monitoring fills
It sets.
Background technology：
As shown in Figure 1, existing machinery forcing press transmission mechanism includes mainly clutch, flywheel, high speed gear shaft, centre
The components such as axis, herringbone bear, brake, chain, cam controller, eccentric gear, mandrel and connecting rod, wherein brake are machinery
One of critical piece of forcing press.
Currently, big machinery forcing press generally uses the brake of friction block type, this kind of brake to pass through air pressure in the market
Coordinate the on-off action of control brake with spring, and then realizes the connection and action of entire transmission system.In real work, system
Dynamic device is controlled with clutch using pneumatic interlocking, and when starting the stroke of a press, electromagnetism bivalve and two-position three way magnetic valve are simultaneously
Action, compressed air rapidly enters brake through electromagnetism bivalve makes brake disc disengage, and then clutch ventilation, which combines, drives transmission
Mechanism operates；When the stroke of a press to be stopped, electromagnetism bivalve acts simultaneously with solenoid valve, clutch cylinder exhaust, frictional disk
It disengages under the action of the spring, power, which transmits, to be cut off, flywheel idle running.Meanwhile the compressed air in stopper cylinder is double through electromagnetism
Valve final vacuum, brake disc are braked rapidly under the action of tripping spring, by secondary part, and sliding block is out of service.

Signal receiver one end end face distance is 5mm.
Pulsed signal device 4 is arranged on brake seat 6.
The installation of the present invention, course of work explanation：
Brake spring pin 33 is first passed through into brake seat 6 when installation and is fixed with holding screw, then by brake seat 6
It is fixed on brake support base 5, piston 13 is mounted in the plunger shaft in brake seat 6, brake with bolt and washer
Frictional disk 10 is mounted on expansion set 11 on high speed gear shaft 2, is used in combination platen 19 and eye bolt to compress, RFID chip built in two pieces
12 brake pads 9 is diagonally mounted in brake friction disk 10, remaining installs common brake pads 9, and ensures
12 uniform thickness of each brake pads, braking platen 8 are pressed in across brake spring pin 33 on brake pads 9, adjustment installation
Jackscrew 7 and nut in braking platen 8 ensure that 13 side plane of piston is concordant with brake seat 6, then inside are cased with spacer sleeve
34 spring 35 is fixed on spring washer 36 and nut on spring catch 33, and completes the setting of pretightning force required for spring 35,
And ensure that the gap between spacer sleeve 34 and spring washer 36 is 2mm, each spring catch 33 is then connected into one with connection disk 37
A entirety simultaneously tightens fixation with nut, prevents single spring catch 33 from causing the dangerous generation that flies out because of fatigue fracture.Start pressure
When power machine stroke, electromagnetism bivalve and two-position three way magnetic valve act simultaneously, and compressed air rapidly enters brake 1 through bivalve, living
Plug 13 by jackscrew 7 drive braking platen 8 after move, 8 compressed spring 33 of braking platen, when displacement reaches 2mm, spacer sleeve 34 with
Spring washer 36 contacts, and is moved after can not continuing, and brake 1 completes brake pads 9 and disengages flow.
(1) close to the positions switch A16 to just U-shaped adjust pad 15,15 thickness of U-shaped adjust pad is 2mm, close to switch
A16 accuracy of detection is 4mm, with the abrasion of brake pads 9, effect of the braking platen 8 in spring 35 after system device 1 is vented
Down stroke gradually increases, when the abrasion of brake pads 9 reaches 2mm, in braking platen 8 close to switch A16 and U-shaped adjustment
Distance between gasket 15 is exactly 4mm, sends a signal to PLC controller close to switch A16, system alarm is simultaneously shut down, touch screen
Prompt：" reducing brake adjust pad thickness 2mm ".When adjustment, operator touch screen select " repair ", system can automatically by
Sliding block is adjusted to lower dead point position, while safety cock enters, and then stops main motor.Then operator incites somebody to action according to display screen prompting
Fixing nut on spring catch 33 is completed according to the corresponding number of turns of system prompt data rotation 2mm (or corner amount) needed for spring 35
The recovery of pretightning force is wanted, while measuring guarantee and being sleeved on spring catch 33 between the spacer sleeve 34 in spring 35 and spring washer 36
Gap is 2mm, and the nut being coupled outside disk 37 is then tightened fixation, prevents from, because of 33 fatigue fracture of single spring catch, causing spring
35 danger to fly out are finally mounted on the bolt and washer of the U-shaped adjust pad 15 in 6 outer fixed seat 14 of Brake Block in release,
It extracts 1 U-shaped adjust pad 15 out, then all bolts and washer is tightened by torque demand, and fasten locking iron wire.It is close to open
PLC control system after A16 can't detect signal to be closed automatically to restore, after the completion of adjustment, operator selects reset key on the touchscreen,
Electric motor starting, PLC control system automatically can reset to sliding block stop position according to absolute value formula rotary encoder data upper dead
Point, safety cock remove, and mechanical press restores normal work.
(2) it is worked at the same time close to switch B29 and rotary encoder 23, when forcing press is in top dead-centre, 31 notch of cam
32 faces are close to switch B29, close to switch B29 no signals output.It is opened from system signals to the exhaust of electromagnetism valve events brake 1
Begin the angle that rotary encoder 23 is rotated until rotary encoder 23 stops rotating no signal output, is recorded in advance in system
Enter corresponding 9 wear data of brake pads of each stop angle, system is constantly monitored and shone according to the numeric ratio in database
It is corresponding, intelligent decision brake pads abrasion situation, and show and prompt or control operating condition on the touchscreen.
(3) pulsed signal device 4 is mounted on bolt on brake seat 6, and PLC control system is connected to data line
On, RFID chip 12 is built at 9 one side end face 5mm of brake pads, and is made marks in the side, brake seat 6 and system
8 material identical of dynamic pressure disk ensures that brake pads both sides wear extent is identical, in brake friction disk when to prevent error from installing
10 diagonal positions place the brake pads 9 of RFID chip 12 built in 2 pieces, and will have label side to be filled close to pulsed signal
4 are set, pulsed signal device 4 can detect the data feedback of RFID chip 12 in brake pads 9 in real time, there is feedback
When illustrate that brake pads 9 not may wear to the degree to be replaced, by long-term use, U-shaped adjust pad 15 gradually adjusts use
It is complete, when 9 wear extent of brake pads reaches 10mm, 12 wear-out failure of RFID chip in brake pads 9, pulse letter
Number reception device 4 can't detect data feedback, and system alarm PLC control pressure machines are stopped, while touch screen prompts：It " asks
Replace brake pad ".When replacement, operator selects " replacement " in touch screen, and sliding block can be adjusted to lower dead point position by system automatically, so
After stop main motor, while safety cock enters.Then operator is more changed jobs, after the completion of replacing brake pads 9,
Select reset key, electric motor starting, PLC controller automatically can be stopped sliding block according to absolute value formula rotary encoder data on touch screen
Stop bit, which is set, resets to top dead-centre, and safety cock removes, mechanical press normal operating conditions.
Brake pads wear extent inspection in mechanical press brake pads intelligent measuring and control device of the present invention
Surveying control system, transmission shaft rotation angle detecting and controlling system, brake pad replacement alarm control system can be accurately and timely automatic
Control brake brake pad abrasion condition is detected, the requirement to worker's professional knowledge, and energy Improving The Quality of Products, energy are reduced
Better meet the intelligent needs of mechanical press automatic production line.
Above-mentioned specific implementation mode cannot function as limiting the scope of the invention, for the technology people of the art
