Background technology
Metallurgical industry is important raw and semifinished materials industries department, for each department of national economy provides metal material, is also the material base of economic development.Since China's reform and opening-up, national economy is increased fast, and " scientific and technical innovation, autonomous innovation " become the main flow of current industrial development.China Metallurgical Industry's scientific and technological level goes strong, and has developed into an industry complete, and production capacity is strong, and the comprehensive industry of technical strength richness is occupied very important status in national product and national defense construction.In metallurgy industry, withdrawal straightening machine is the equipment for casting blank of continuous casting machine aligning.Existing withdrawal straightening machine adopts the transmission system of one-drag-two driving in strand straightening process.The speed reducer drive of two dual outputs of a driven by motor of transmission adopted, motor selects power large, and occupation of land space is larger, and installation and maintenance are more difficult, and energy consumption is large, has affected the service life of reductor, does not reach ideal effect, thereby affects the production efficiency of continuous casting.The leading of existing withdrawal straightening machine holds employing ball bearing to roller bearing, and service life is short, non-refractory, and the butter of will often annotating, and working service is inconvenient.Three lower rolls of existing withdrawal straightening machine and straightening frame adopt rectangle gathering sill location, and when installation and maintenance, locating effect is bad, easily causes axial float, and bearing block easily damages.In order to address these problems, scientific research personnel of the same trade constantly carried out Improvement to withdrawal straightening machine in recent years, although obtain some progress, still existed the technical barrier that is difficult to overcome in production practices.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of novel energy-conserving withdrawal straightening machine is provided, and installation and maintenance are convenient, adopts the kind of drive of a speed reducer drive of a driven by motor, has reduced machine loss, has saved the energy.Leading to roller bearing employing oiliness bearing replacement ball bearing, reduced maintenance cost.Adopt four straight pin location, good positioning effect, has eliminated displacement axially and radially, has extended the service life of bearing block.
The utility model solves the technical scheme that its technical problem adopts: contain on-the-spot paralell, motor, shaft joint, reductor a, straightening frame, oil cylinder, withdrawal straightening machine top chock, drive link a, drive link b, withdrawal straightening machine is uploaded action roller, reductor b, withdrawal straightening machine lower driving roller, guide roller support, guide roller, oiliness bearing, axle ring washer, guiding roll shaft, withdrawal straightening machine roller, straight pin, withdrawal straightening machine step, motor, shaft joint, after connecting successively, reductor a three is connected with on-the-spot paralell, output and drive link a under two reductor a, after drive link b is connected, then be connected with two reductor b, two reductor b upload action roller with withdrawal straightening machine respectively, withdrawal straightening machine lower driving roller is connected, and the top of straightening frame is provided with oil cylinder, and oil cylinder is connected with withdrawal straightening machine top chock, guide roller support, withdrawal straightening machine step is connected with the bottom of straightening frame, in guide roller, be provided with oiliness bearing, oiliness bearing is connected with ring washer with axle, hex bolts is connected guiding roll shaft with guide roller, guide roller support is connected with guide roller, withdrawal straightening machine step is provided with withdrawal straightening machine roller, in withdrawal straightening machine step, is provided with straight pin, and straight pin is located by connecting withdrawal straightening machine roller and straightening frame.
The know-why that the utility model adopts is: existing withdrawal straightening machine is improved to innovation, and process is calculated and experiment, drives two speed reducer drives to change two on an original motor and drags the i.e. kind of drive of a reductor of a motor drive of two transmissions.Select the motor of two 7.5KW just can meet instructions for use, power-dissipation-reduced half, extended the service life of reductor, floor space has reduced 1/3rd, increase installation and maintenance space, reduced machine loss and save the energy, responded the call of national energy-saving and emission-reduction, extension device service life, thus the production efficiency of continuous casting improved.The ball bearing that guide roller before existing withdrawal straightening machine is adopted changes oiliness bearing into, easy to maintenance, has reduced maintenance cost.Three lower rolls of existing withdrawal straightening machine and straightening frame gathering sill location are changed into four straight pin location, and good positioning effect, has eliminated displacement axially and radially, has extended the service life of bearing block.
The utility model beneficial effect is: the kind of drive of two transmissions is dragged in this withdrawal straightening machine employing two, has saved the energy, has reduced the loss of machine.Adopt oiliness bearing to replace ball bearing, operation and maintenance is convenient, has reduced maintenance cost.Adopt straight pin that withdrawal straightening machine roller and straightening frame are located by connecting, eliminated displacement axially and radially, extended service life of equipment.
