Linear adjustment device for aligning transverse ribs of high-torque screw-thread steel

Abstract

The invention relates to a linear adjustment device for aligning transverse ribs of high-torque screw-thread steel, belonging to the technical field of steel rolling machinery. In the invention, a left adjustment disc and a right adjustment disc are adjusted to relatively rotate by adjusting a wedge to move up and down; the position of the wedge is fixed by an adjusting bolt when the left adjustment disc and the right adjustment disc are adjusted to needed angles so that the variation of an angle (phase) is generated between a left roll shaft sleeve and a left universal joint shaft which are respectively connected with the left adjustment disc and the right adjustment disc, and thus, the ultimate purpose of adjusting the relative angle (phase) between two rolls is ultimately achieved.

Description

technical field [0001] The invention relates to a high-torque threaded steel transverse rib alignment linear adjustment device, which belongs to the technical field of steel rolling machinery. Background technique [0002] Finish-rolled rebar is a rebar developed by the former Federal Republic of Germany in the 1970s. The shape of the steel bar requires that any cross-section can be connected with a connector with a matching internal thread, or anchored with a matching nut. The threads of the left and right parts of the fine-rolled threaded steel bar are helical, that is, the finished-rolled threaded steel bar can be assembled like a bolt with a nut. It mainly solves the problem that high-strength steel bars cannot be welded, such as GBT-20065-2006 threaded steel bars for prestressed concrete; it also solves the problem of construction on sites that do not have welding conditions, such as underground mine anchorage in coal mines. [0003] The core technology of finishing t...

Problems solved by technology

The disadvantage of this patent is that the structure is complicated and the production cost is high; practice has proved that 4-5 connecting bolts need to be loosened every time rolling is put on the line, and the phase adjustment time is at least about 1 hour, which is time-consuming and laborious, and cannot achieve fast and efficient adjustment

The disadvantage of this patent application is that: the main part of the regulator for transmission torque is two ball stud pins, the contact area is small, and it is not resistant to the impact of biting steel

When the adjustment angle is close to the limit position, the pressure direction of the column pin is seriously deviated from the axial direction, and the thread of the column pin is easily damaged.

When producing GBT-20065-2006 prestressed concrete rebar PSB785, PSB830 and other ultra-high-strength finish-rolled rebar, transmission failure is prone to occur, so it cannot be adapted to large-scale production
