Abstract
The utility model relates parts of strip steel process equipment, in particular to a combined high manganese steel tension roller which comprises a drum, a shaft and annular plates which hare arranged at the two ends of the drum, and is characterized in that the drum is a barrel which is cast by adopting high manganese steel ZGMn13-4, shaft sleeves are respectively welded at the inner rings of the two annular plates, the shaft sleeves and the shaft are welded into a whole, connection sleeves are respectively welded at the outer rings of the two annular plates, the excircle surfaces of the connection sleeves are sleeved with the inner circle surfaces of the drum in a transition fit manner, and the connection sleeves and the drum are assembled into a whole through adopting a plurality of connecting pieces which hare uniformly distribution along the circumferential direction. The combined high manganese steel tension roller is used for solving the problems that the existing tension roller has low finished product rate and is high in manufacturing cost, and is mainly suitable for the strip steel process equipment in the metallurgic processing industry.
Description
(1). technical field: the utility model relates to the parts in the metallurgical industry band steel treatment facility, especially a kind of assembly type potassium steel jockey pulley.
(2). background technology: jockey pulley is one of important spare part in the metallurgical industry band steel treatment facility, and its working environment is special, requires roller to have high accuracy, high rigidity and anti-wear performance.Existing jockey pulley is to adopt the 35# steel to process roller, through left and right sides former and the axle one that is welded, processes jockey pulley then; For high rigidity and the anti-wear performance that improves roller, must be to the roller processing of quenching, so the production cycle of roller is long; Yield rate is low, and production cost is higher.
The (3) summary of the invention: the purpose of the utility model will solve exactly that the existing jockey pulley production cycle is long, and yield rate is low, and the problem that production cost is high provides a kind of assembly type potassium steel jockey pulley.
The utility model design principle is: select high rigidity, potassium steel ZGMn13-4 that anti-wear performance is good for use; Adopt centrifuge to be cast into roller; Need not to quench,, adopt connector and former to be linked and packed because the welding performance of potassium steel is relatively poor; And disc can select for use ordinary steel such as 35# steel, A3 steel etc. to process, former then can with the axle one that is welded.
The concrete scheme of the utility model is: a kind of assembly type potassium steel jockey pulley; Include roller, axle and be arranged on the annular disc at roller two ends; It is characterized in that: said roller is to adopt potassium steel ZGMn-4 to be cast into cylinder, at the inner ring of the two annular disc axle sleeve that respectively has been welded, and axle sleeve and the axle one that is welded; At the cylindrical of the two annular disc adapter sleeve that respectively has been welded
The inner headed face interference fit suit of the periphery of adapter sleeve and roller, and the some connectors dresses that between adapter sleeve and roller, adopt the edge circumferentially to be uniformly distributed with are one.
Being connected between adapter sleeve described in the utility model and the roller can have multiple mode, and three kinds of typical way are provided here:
Mode one: be to adopt bolt to be connected between adapter sleeve described in the utility model and the roller, bolt between adapter sleeve and roller from inside to outside radial arrangement be connected;
Mode two: be to adopt pin to be connected between adapter sleeve described in the utility model and the roller, an end of pin is inserted in the blind hole of roller inwall, the other end be contained in the pin hole of adapter sleeve and with the adapter sleeve weldering be one;
Mode three: being to adopt awl bar bolt to be connected between adapter sleeve described in the utility model and the roller, is the little bellmouth of imperial palace on adapter sleeve and roller, having outside, bores the bar bolt and is inserted in the bellmouth, and the inner employing nut of boring the bar bolt is fastening.
The utility model need not the processing of quenching, and is with short production cycle, and yield rate is high, and production cost reduces.Adopt the potassium steel roller, hardness is high, and anti-wear performance is good.Adopt package assembly, in case the roller wearing and tearing can be convenient for changing maintenance, economical with materials, processing cost improve stock utilization.
