Technical field
The utility model relates to the pneumatic type friction clutch, low many disc types of the inertia air operated friction clutch on the particularly large-scale guillotine shear.
Background technique
For the machine overload protection of big machinery guillotine shear, be difficult point of domestic mechanical guillotine shear, domestic also solution well at present.Domestic many mechanical shear machines are made the mechanical guillotine shear that enterprise produces, and great majority are to adopt rotating key clutch, at coupling several connecting pins are arranged, and the surface plays the certain protection effect.But in case turn key is stuck or twist off, connecting pin does not shield, and often causes gearwheel to break, main shaft twist and warping, major accidents such as wallboard fracture.Since the material of connecting pin, size, thermal treatment quality.Machining accuracy is not that calibration is inhomogeneous, can only be used for the mechanical guillotine shear below 20 millimeters at most with the hole of numerical control machine tool processing, and minority machinery shear machine is made enterprise in addition, for mechanical guillotine shear.In order to solve machine overload protection, adopt magnetic clutch, be easy to generate remanent magnetism, often to remove magnetic, so generally only be used for the mechanical guillotine shear below 8 millimeters.Air operated friction clutch is used in the mechanical guillotine shear more than 20 millimeters, and first will stablize air pressure, gas holder, the brake pad of second air operated friction clutch is nonmetal, and sheet is arranged, and has just brought into use just all right, use 2-3 after the month, heating, abrasion are serious, skid easily.If begin to cut the steel plate of 30 millimeters thick, after 2-3 month, can only shear the steel plate of 20-15 millimeters thick, otherwise just throw off automatically.Domestic other mechanical guillotine shears are that single face drives, and air operated friction clutch is installed high speed shaft, and abrasion is serious, generates heat, skids.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of flexible movements reliable, and long service life is adjusted low many disc types of the inertia air operated friction clutch on the large-scale guillotine shear easy to maintenance.
The technical solution of the utility model: low many disc types of the inertia air operated friction clutch on a kind of large-scale guillotine shear, it is characterized in that described this clutch is arranged on the intermediate propeller shaft, this clutch is to comprise driven disc, driving disc, end cap, intermediate propeller shaft end cap, piston, seal ring, brake pad, axle sleeve, felt collar, method shrouding disc, intermediate propeller shaft small gear, intermediate propeller shaft, pressure regulating spring and clutch body.
Its outer rim of described driving disc is provided with uniform friction disk, and brake pad all is housed on each friction disk, between its end cap and the driving disc piston is housed, and the piston shaft on the piston touches mutually with brake pad on the friction disk; Driving disc is connected with intermediate propeller shaft by flat key and axle sleeve, and the intermediate propeller shaft end cap is arranged on the intermediate propeller shaft end, and it is fastening by screw to push down the driving disc end; Described driven disc is connected with the intermediate propeller shaft small gear with locating stud and flange plate by bolt.
Described end cap is the air inlet end cap, its air inlet end cap covers by seal ring and piston, and it is fastening and constitute many disc types air operated friction clutch, the pressure regulating spring of the clutch time unanimity described adjusting elastic force of the axial arranged outside of air inlet end cap, that make air operated friction clutch, the two pairs of gear strict synchronism in both sides with clutch body.
Described driving disc outer rim is provided with eight uniform friction disks, and the brake pad of semi-metallic based high-abrasive material respectively is housed on eight friction disks.
The utility model is that a kind of heat is cut mechanical guillotine shear; in order to ensure bilateral driving, two pairs of gear strict synchronism, and the machine overload protection of solution big machinery guillotine shear; transmitting torque; problems such as the brake pad long service life is generated heat and lacked, and is non-slip; domestic other mechanical guillotine shears are that single face drives; air operated friction clutch is installed high speed shaft, and abrasion is serious, generates heat, skids.And our design is that the large-scale many disc types air operated friction clutch of low inertia is installed the jack shaft two ends, because speed is low, heating is few, and is non-slip, we adopt is that low inertia large-scale many disc types air operated friction clutch, particularly brake pad are adopted the semi-metallic based brake pad of import.Guarantee two pairs of gear strict synchronism, must take following measure:
1,,, make upper tool post run to upper dead center and lower dead point position is very accurate with optoelectronic switch control to the upper dead center and the lower dead centre of upper tool post.Send signal by electrical control circuit, guarantee synchronously.
2, in order to guarantee two the large-scale many disc types air operated friction clutch of low inertia suction pressure unanimities, the air valve action accurately.We have installed a large-scale gas holder on gas circuit, make the pressure unanimity that enters air operated friction clutch, and the air valve action accurately.
3, by regulating two pressure springs that make two large-scale many disc types air operated friction clutches of low inertia, make the clutch time unanimity of air operated friction clutch, take these measures, guaranteed two pairs of gear strict synchronism through experiment showed.
The large-scale many disc types air operated friction clutch of this low inertia is installed on the intermediate propeller shaft, and clutch is provided with driving disc and driven disc.Driving disc is connected with intermediate propeller shaft by flat key, and its outer rim is equipped with eight secondary friction disks, on every bracket panel brake pad is housed, and adopts semi-metallic based high-abrasive material.Driven disc is connected with the both sides small gear with locating stud by bolt, and its inner rim is equipped with joint element.Piston (axially) is housed between driven disc and the driving disc, and when air inlet, piston inwardly moves, the pressing friction piece, and clutch, after the exhaust, under the thrust of Returnning spring, piston moves outward, and brake pad separates, throw-out-of clutch.During same former should overloading, clutch is also thrown off.The elastic force of Regulation spring can change the size of clutch time and frictional force.
When the monolateral amount of friction 2mm of brake pad, total amount of friction 16mm, must change brake pad, brake pad is an easily damaged parts.By facts have proved, can reach 2 years working life, and supply gas pressure is 0.55Mpa.
The utility model adopts the low large-scale many disc types air operated friction clutch of inertia, and its function is to play a part the overload mechanical protection, and the both sides small gear is carried out clutch, and transmitting torque guarantees the two pairs of gear strict synchronism in both sides.The characteristics of the large-scale many disc types air operated friction clutch of this low inertia: being installed on the lower velocity shaft, is that low inertia has eight secondary disc type brake pads, and this brake pad adopts semi-metallic based high-abrasive material.Make its this clutch operating flexibility and reliability, long service life is adjusted easy to maintenance.
