Installation of the 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 high speed gear shaft 2 with expansion set 11, and is compressed with platen 19 and eye bolt, 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 guarantees Each 12 uniform thickness of brake pads, braking platen 8 pass through brake spring pin 33 and are pressed on brake pads 9, adjustment installation Jackscrew 7 and nut in braking platen 8 guarantee 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 catch 33 with spring washer 36 and nut, and completes the setting of pretightning force required for spring 35, And guarantee 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 simultaneously operation, compressed air rapidly enter brake 1 through bivalve, living Plug 13 by jackscrew 7 drive braking platen 8 move back, 8 compressed spring 33 of braking platen, when displacement reaches 2mm, spacer sleeve 34 with Spring washer 36 contacts, and can not continue to move back, and brake 1 completes brake pads 9 and disengages process.
(1) close to the position switch A16 to just U-shaped adjustment gasket 15, U-shaped 15 thickness of adjustment gasket is 2mm, close to switch A16 detection accuracy 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: " reduce brake and adjust spacer thickness 2mm ".When adjustment, operator touch screen select " maintenance ", 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 Fixture nut on spring catch 33 is completed needed for spring 35 according to the corresponding circle number of system prompt data rotation 2mm (or corner amount) The recovery of pretightning force is wanted, while measuring guarantee and covering between the spacer sleeve 34 and spring washer 36 in 33 upper spring 35 of spring catch Gap is 2mm, and the nut being coupled outside disk 37 is then tightened fixation, prevents from causing spring because of single 33 fatigue fracture of spring catch 35 danger to fly out, the bolt and washer of the U-shaped adjustment gasket 15 being finally mounted in the outer fixing seat 14 of Brake Block 6 in release, It extracts 1 U-shaped adjustment gasket 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 is restored automatically after pass A16 can't detect signal, and 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 to work normally.
(2) it is worked at the same time close to switch B29 and rotary encoder 23, when press machine is in top dead-centre, 31 notch of cam 32 faces are exported close to switch B29 close to switch B29 no signal.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, records 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 brake seat 6 with bolt, is connected to PLC control system with 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 of dynamic pressure disk is identical, guarantees that brake pads two sides abrasion loss 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 fill close to pulsed signal Set 4, pulsed signal device 4 can in real-time detection to brake pads 9 RFID chip 12 data feedback, have feedback When illustrate that brake pads 9 not may wear to the degree to be replaced, by long-term use, U-shaped adjustment gasket 15 gradually adjusts use It is complete, when 9 abrasion loss 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 press machine stops working, while touch screen prompts: " asking Replace friction block ".When replacement, operator selects " replacement " in touch screen, and sliding block can be adjusted to lower dead point position automatically by system, so After stop main motor, while safety cock enters.Then operator is more changed jobs, after the completion of replacing brake pads 9, Reset key, electric motor starting are selected on touch screen, PLC controller automatically can stop sliding block according to absolute value formula rotary encoder data Stop bit, which is set, resets to top dead-centre, and safety cock removes, mechanical press normal operating conditions.
Brake pads abrasion loss 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, friction block replacement alarm control system can be accurately and timely automatic Control brake friction block 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 embodiment cannot function as limiting the scope of the invention, for the technology people of the art For member, any alternate modification or transformation made to embodiment of the present invention are fallen within the scope of protection of the present invention.
Place is not described in detail by the present invention, is the well-known technique of those skilled in the art of the present technique.
