Abstract
A Belleville spring type overload protecting flywheel comprises an inner wheel body, outer wheel bodies, middle wheel bodies, upper friction sheets, lower friction sheets, tensioning bolts, pretightening Belleville springs and fastening nuts, wherein the inner wheel body is mounted on a screw of a press, the outer wheel bodies are mounted on the upper portion of the inner wheel body, each middle wheel body is positioned on the lower portion of the inner wheel body and mounted between the inner wheel body and the corresponding outer wheel body, the upper friction sheets are mounted among the inner wheel body and the outer wheel bodies, the lower friction sheets are mounted among the inner wheel body and the middle wheel bodies, the tensioning bolts penetrate into through holes of the corresponding middle wheel bodies and the corresponding outer wheel bodies and fix the corresponding middle wheel bodies and the corresponding outer wheel bodies together, the pretightening Belleville springs are mounted on the corresponding tensioning bolts and closely abutted to the upper end faces of the corresponding outer wheel bodies, and the fastening nuts are mounted on the corresponding tensioning bolts. The Belleville spring type overload protecting flywheel is simple in structure, convenient in operation, overload protective, safe, reliable, capable of leading the service life of the press to be longer and widely applicable to screw presses.
Description
Technical field the present invention relates to a kind of disk spring type overload protection flywheel, can be widely used in the fly press.
The existing fly press of background technology, poor because of its flywheel overload capacity, in case overload can damage forcing press and parts thereof, service life is short.
Summary of the invention the object of the present invention is to provide the disk spring type overload protection flywheel of a kind of simple in structure, easy to operate, overload protection, safe and reliable, machine long service life.
In order to achieve the above object; Disk spring type overload protection flywheel of the present invention comprises the interior wheel body that is installed on the forcing press screw rod, the outer wheel body on wheel body top in being installed in; In interior wheel body bottom is installed in wheel body and outside middle wheel body between the wheel body; Upper friction plate in being installed between wheel body and the outer wheel body, the following friction plate in being installed between wheel body and the middle wheel body, wheel body is with outer wheel body through hole and with its turnbuckle that tightens together in the middle of passing; Be installed on the turnbuckle and, be installed in the clamp nut on the turnbuckle near the pretension dish spring of outer wheel body upper surface.
Disk spring type overload protection flywheel of the present invention adopts the disk spring type overcurrent protection structure, and its operation principle is: through pretension dish spring, and preset pressure machine hitting power limit value, the torsional load that restriction is transmitted is no more than setting value.When hitting load when surpassing the predefined power of skidding; Outer wheel body of flywheel and middle wheel body skid with respect to interior wheel body; Make that portion of energy is consumed between outer wheel body and the interior wheel body, on the rubbing surface of the friction plate between middle wheel body and the interior wheel body; Thereby reduced blow energy, also just reduced hitting power.Like this, just can prevent that stressed part from destroying because of overload, play overload protective function, reach the purpose of protection machine, thereby improve the service life of machine.
Disk spring type overload protection flywheel of the present invention, simple in structure, easy to operate.When exceeding the predetermined load strike, outer wheel body, middle wheel body will skid with respect to interior wheel body, eliminate excess energy, avoid because of the overload damage equipment.Like this, the equipment that guaranteed can be exported bigger blow energy, can when exporting bigger hitting power, be without prejudice through flywheel slipping protection equipment again.
In sum, disk spring type overload protection flywheel of the present invention, simple in structure, easy to operate, overload protection, safe and reliable, the machine long service life.
Description of drawings is done explanation further below in conjunction with accompanying drawing and embodiment to the present invention.
Fig. 1 is a structural representation of the present invention.
The specific embodiment is in Fig. 1; Disk spring type overload protection flywheel of the present invention comprises the interior wheel body 1 that is installed on the forcing press screw rod 9, the outer wheel body 2 on wheel body top in being installed in; In interior wheel body bottom is installed in wheel body and outside middle wheel body 3 between the wheel body; Upper friction plate 4 in being installed between wheel body and the outer wheel body, the following friction plate 5 in being installed between wheel body and the middle wheel body, wheel body is with outer wheel body through hole and with its turnbuckle that tightens together 6 in the middle of passing; Be installed on the turnbuckle and, be installed in the clamp nut 8 on the turnbuckle near the pretension dish spring 7 of outer wheel body upper surface.
