Description
Technical field
The present invention relates to bearing mnanufacture technical field, and in particular to a kind of bearing steel pipe cutting equipment.
Background technology
The blanking procedure of bearing machining, next procedure is entered back into after exactly steel pipe is cut according to one fixed width.Under
Material process is the basis of subsequent processing operations, and precision, the efficiency of blanking procedure directly influence the quality and cost of product quality
Height.In recent years, the development of pipe cutting machine has made great progress, but the problems such as complicated, price is high be present.
Many manufacturing enterprises ensure the precision of blanking still through machinery positioning is manually added now.Found in investigation, should
Kind equipment chipping allowance is big, and consumptive material is more, and manual measurement can not ensure precision, and processing efficiency is relatively low.Also someone designs one kind at present
The equipment of tubing is cut by laser, but equipment cost height be present, cutting surface hardness becomes big the problems such as influenceing following process.
In order to solve the above problems, Application No. CN201110050988.9 domestic patent of invention discloses a kind of bearing
With the cutting equipment and cutting technique of steel pipe, including feeding machanism and cutting mechanism, feeding machanism includes motor, leading screw, guiding
Bar, the narrow clamping device for clamping tubing and wide clamping device and the narrow clamping device of driving and wide clamping device fold up dynamic
The hydraulic system of work；Wide clamping device position is fixed, and the screw mandrel connection motor for being provided with narrow clamping device is driven by it；Cutting machine
Structure includes cutting drive mechanism, blade, buncher, microswitch；The microswitch that control buncher opens and closes is positioned at pipe
The cutting steel ring extension position that material is stretched out outside wide clamping device, blade are installed on buncher and are driven by it rotation, while electricity
Machine is fixedly connected with the output shaft of cutting drive mechanism.Motor driven ball screw is used to realize tubing feeding to improve positioning accurate
Degree.Air pressure fluid cylinder transmission work is rapid in cutting drive mechanism, be of relatively low cost and hydraulic drive stable working, thrust are big etc.
To advantage, the feed motion of blade is realized to increase the stability of cutting movement.
But said apparatus still suffers from defect：, can not when leading screw reaches range because leading screw has range limitation
Continue forward, this time width gripping means grips tubing, then motor reversal, narrow clamping device resets return, then narrow to clamp dress
Clamping tubing is put, when front at steel pipe end is located at narrow clamping device reset, narrow clamping device can not clamp tubing, cause pipe
Material can not continue to be fed forward to be cut, and this part tubing clout is treated as waste material due to that can not cut, and causes tubing
The serious waste of clout.
