Abstract
The invention relates to a pressure roller rotary supporting structure. The pressure roller rotary supporting structure is characterized by comprising conical roller bearings, a deep groove ball bearing and a shaft sleeve; a pressure roller shaft is sleeved with the conical roller bearings, the deep groove ball bearing and the shaft sleeve, the conical roller bearings, the deep groove ball bearing and the shaft sleeve are loaded in inner holes of a pressure roller, the two conical roller bearings are symmetrically arranged, the deep groove ball bearing and the shaft sleeve are arranged between the two conical roller bearings, the conical roller bearing on the inner side is limited through a step arranged on the pressure roller shaft, and the conical roller bearing on the outer side is locked and limited through a locking assembly. The pressure roller rotary supporting structure is novel in structural design, H-steel can be accurately straightened, the product accuracy and the machining efficiency of the H-steel are greatly improved, and the automation degree of the H-steel is greatly increased.
Description
Technical field
The present invention relates to pressing roller rotational support structure, belong to steel construction processing and manufacturing technical field.
Background technology
Along with the fast development of China's steel construction industry, the H profile steel for steel-structure factory building develops to meticulous type and heavy duty detergent day by day, and the group how improving H profile steel founds precision, working (machining) efficiency and automaticity, has become the difficult problem that steel construction industry must overcome.
H profile steel is by two blocks of wing plates and assembled group of one block of web is vertical forms, and the relative position relation of web and wing plate directly has influence on the qualification rate of H profile steel finished product.Existing general group to found machine be all by carrying out the setting of artificial position to the assembly welding of H profile steel needed in advance, and then carry out H-shaped steel assembly welding, adopt the position that the H profile steel of processing in this way is difficult to locate exactly each plate, always there will be some deviations, this just needs to use follow-up rectification step.But current arbor press by structural design too complicated, be not suitable for production requirement, and structure too simple exist correct the low problem of precision.Pressing roller is the vitals in arbor press, and its traveling comfort has material impact to rectification precision.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of pressing roller rotational support structure, its novel in structural design, can accurate straightening H shaped steel, substantially increase the Product Precision of H profile steel, working (machining) efficiency and automaticity.
According to technical scheme provided by the invention: pressing roller rotational support structure, it is characterized in that: comprise taper roll bearing, deep groove ball bearing and axle sleeve, taper roll bearing, deep groove ball bearing and axle sleeve to be sleeved on nip drum wheel shaft and to load in the endoporus of pressing roller, two taper roll bearings are arranged symmetrically with, deep groove ball bearing and axle sleeve are arranged between two taper roll bearings, the step that the taper roll bearing of inner side is provided with by nip drum wheel shaft is spacing, and the taper roll bearing in outside is locked spacing by latch assembly.
As a further improvement on the present invention, described latch assembly comprises round nut and packing ring, described pressing roller shaft end is provided with external thread section, described round nut is screwed onto on this external thread section, gasket sleeve is contained on nip drum wheel shaft, round nut screws and withstands packing ring, and packing ring withstands the taper roll bearing of adjacent side.
As a further improvement on the present invention, the opening portion of described pressing roller endoporus is provided with blind nut, and round nut, packing ring, taper roll bearing, deep groove ball bearing and axle sleeve are encapsulated in the endoporus of pressing roller by described blind nut.
compared with prior art, tool has the following advantages in the present invention:novel in structural design of the present invention, can accurate straightening H shaped steel, substantially increases the Product Precision of H profile steel, working (machining) efficiency and automaticity.
