Abstract
The utility model relates to an abrasive-disk cutter with a pneumatic fail-safe brake. The abrasive-disk cutter comprises a main motor (1), a coupling (3) with a brake disc, a speed increaser (4), a slitting disc (5) and a bracket. The main motor (1) and the speed increaser (4) are fixed on the bracket, the output end of the main motor (1) is connected with the input end of the speed increaser (4) through the coupling (3) with the brake disc, and the slitting disc (5) is arranged at the output end of the speed increaser (4). The abrasive-disk cutter also comprises a pneumatic fail-safe brake (2) which is fixed on the bracket and positioned at the periphery of the coupling (3) with the brake disc, so as to match the coupling (3) with the brake disc in braking. The slitting disc of the abrasive-disk cutter adopts the pneumatic fail-safe brake for braking, and the pneumatic fail-safe brake is clamped by a spring and can realize pneumatic release. The pneumatic fail-safe brake can stop the main motor when the power is suddenly cut off, thereby preventing accidents and leading the use of the abrasive-disk cutter to be safer and more reliable.
Description
(1) technical field
The utility model relates to a kind of abrasive cutoff saw.The main sawing that realizes steel billet.Belong to steel rolling auxiliary equipment technical field.
(2) background technology
Bar and section bar must be through sawings after milling train comes out.The shearing of general employing cutter, the sawing of metal saw blade or the sawing of abrasive cutoff saw sheet etc.Rail spare with cutter shearing compound section can make the shearing area compressive deformation.Therefore for section rolled pieces such as steel pipe, shaped steel,, must adopt saw to cut off in order to guarantee cross section quality.Abrasive cutoff saw and metal saw is compared, steel grade that can the sawing different materials, and machine vibration is little, advantages such as sawing section fineness height.Along with the increase of client to the steel grade demand, the raising that cross section quality requires, the application of abrasive cutoff saw is also more and more widely.
Steel rolling auxiliary equipment ordinary production technology is that discharge (batch of material) or single material are on approach table, material is transported to the shear gauge place through approach table, behind scale, after material is clamped by the horizontal/vertical clamping device, abrasive cutoff saw with the moving telescopic location that moves to requirement of adjust tilt jack, calculates main motor speed according to calibrating the saw disc size according to the diameter of calibrating size and material automatically subsequently again, according to selected stock removal rate control feed cylinder proportional control valve, cut automatically again.Cutting finishes, and saw disc lifts automatically, and the fast return original position, and the horizontal/vertical clamp mechanism is all unclamped, and approach table will be sawed back scale material and be transported, and material to be cut is continued to repeat to send to, carry out sawing next time.
Before the utility model was made, the saw disc of abrasive cutoff saw in the past can not be braked.When outage suddenly, can not brake, have fortuitous event like this and take place, cause the abrasive cutoff saw safety and reliability relatively poor main motor.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of abrasive cutoff saw with pneumatic fail safe brake that can brake main motor when outage suddenly is provided.
The purpose of this utility model is achieved in that a kind of abrasive cutoff saw with pneumatic fail safe brake; comprise main motor; the shaft coupling of band brake dish; booster engine; saw disc and support; described main motor and booster engine are fixed on the support; described main motor output end links to each other with the input of booster engine by the shaft coupling of band brake dish; saw disc is installed in the output of booster engine; described abrasive cutoff saw also includes a pneumatic fail safe brake; this pneumatic fail safe brake is fixed on the described support; and place the shaft coupling periphery of described band brake dish, cooperate with the shaft coupling stop of band brake dish.During pneumatic inefficacy, pneumatic fail safe brake auto lock brake disc.
It is that spring clamps pneumatic release that pneumatic fail safe brake, pneumatic fail safe brake have been adopted in the saw disc braking of the utility model abrasive cutoff saw.This pneumatic fail safe brake can be braked main motor when outage suddenly, prevents that fortuitous event from taking place, and makes abrasive cutoff saw use safety and reliability.

Fig. 2 is the side view of Fig. 1.
Reference numeral among the figure:
Pneumatic fail safe brake 2
The shaft coupling 3 of band brake dish
Booster engine 4
Saw disc 5.
(5) specific embodiment
Referring to Fig. 1～2, the abrasive cutoff saw with pneumatic fail safe brake that the utility model relates to mainly is made up of shaft coupling 3, booster engine 4, saw disc 5 and the support of main motor 1, band brake dish.Described main motor 1, booster engine 4 and pneumatic fail safe brake 2 are fixed on the support.Described main motor 1 output links to each other with the input of booster engine 4 by the shaft coupling 3 of band brake dish; saw disc 5 is installed in the output of booster engine 4; pneumatic fail safe brake 2 places shaft coupling 3 peripheries of described band brake dish, cooperates with shaft coupling 3 stop of band brake dish.During pneumatic inefficacy, the auto lock brake disc.
Operation principle:
When needs change grinding wheel; at this moment main motor is cut off the power supply; or fortuitous event is when cutting off the power supply suddenly; because the inertia of abrasive cutoff saw saw disc and speedup arbor; the drive saw disc is rotated further; at this moment the spring action on the pneumatic fail safe brake clamps the shaft coupling of band brake dish, thereby realizes main motor braking.
Claims (1)
