Technical field:
The present invention relates to mechanical press technical fields, and in particular to mechanical pressure brake temperature rise automatic measuring and controlling dress
It sets.
Background technique:
As shown in Figure 1, being conventional brake structure chart, brake is one of main component of mechanical press.Currently, city
Big machinery press machine generallys use the brake of friction block type on field, this kind of brake passes through air pressure and spring cooperation control system
The on-off action of dynamic device, and then realize the connection and movement of entire transmission system.In real work, brakes and clutches are used
Pneumatic interlocking control, when starting the stroke of a press, electromagnetism bivalve and two-position three way magnetic valve simultaneously operation, compressed air is through electricity
Magnetic bivalve, which rapidly enters brake, disengages brake disc, and then clutch ventilation, which combines, drives transmission mechanism operating;When stopping
When the stroke of a press, electromagnetism bivalve and solenoid valve are moved at the same time, and stopper cylinder exhaust, frictional disk disengages, and power transmitting is cut
It is disconnected, flywheel idle running.
When mechanical press and robot self-feeding are run under single stroke state, friction block type brake is continuous
Combination, disengage, with brake for a long time, high-frequency operation, the continuous rubbing action of piston, friction block and brake disc, together
When brake inside space relative closure, effective cross-ventilation can not be formed, so that brake related work component and its interior
Portion's friction heat production, temperature constantly increase, and coefficient of friction is caused to reduce, and the reduced performance of brake, friction block accelerates abrasion, causes
Brake service life greatly shortens.It will result in slipping of brake when the abrasion loss of friction block is excessive, make sliding block stamping press
There is product quality problem in deficiency, leads to waste product, and the sliding block reset after slipping of brake is also relatively difficult.It brakes simultaneously
Device part temperatures increase, and size and mechanical property to component itself will also result in the influence of different levels, and then influence braking
The working effect and service life of device, reduce the precision and stability of lathe.Currently, in order to reduce brake temperature, tradition
Way be to install air blower additional outside brake, gap is internally dried to reduce brake temperature on the outside of brake, but
It is that aforesaid way in brake inside can not form effective cross-ventilation and heat exchange, be easy to cause friction deblocking temperature higher and two
The larger phenomenon of the side temperature difference, and air blower can not automatically control air quantity according to brake inside temperature change, and air blower is only
The not only waste of energy that can work always and cannot effectively achieve the effect that reduce brake temperature.In conclusion in brake
Portion's temperature rise is out of control seriously to constrain the development of high speed, precision machinery press machine and mechanical press automatic production line.
