Abstract

The utility model discloses a diamond-blank tilter for a blooming mill. A tumbling mechanism of the tilter is composed of a tumbling body, a swinging shaft, a wedge, a hydraulic cylinder of double-output shaft, a proximity switch, etc., wherein the tumbling mechanism is directly assembled on a manipulator, the tumbling body is a single casting and is connected with the swinging shaft by the wedge, the proximity switch is used as a limit switch, which can realize the turnover of arbitrary angle of the diamond-blank. The utility model provides the simple, practical and reliable diamond-blank tilter for blooming production.

Description

Blooming mill rhombus base tilting gear

The utility model belongs to a kind of tilting gear.

Domestic existing tilting gear is mainly used in the upset rectangular bloom, and is equipped on the bar milk, does not also have rhombus base tilting gear on the blooming mill.Abroad, rhombus base tilting gear is contained on the manipulator afterbody section of picking out, and this section joins together with pre-stressed bolt and manipulator, for this section of balance weight, devices such as support wheel and track are housed in its lower section, next turns over the steel body and adopts the roll-type structure, this tilting gear complex structure, parts are many, and are big at impact endurance test shock, the temperature height, in iron scale and the cooling water abominable production environment how, easy break-down, and maintenance difficult, in addition, this tilting gear is far away from roll, and it is unfavorable to aim at pass in the rhombus base.

The purpose of this utility model is at the prior art deficiency, for breaking down production provides a kind of simple, practical and reliable rhombus base tilting gear.

A kind of by operating desk, power cabinet, the blooming mill that Hydraulic Station and tilting gear structure are formed rhombus base tilting gear structure.The tilting gear structure is by turning over steel body, swinging axle, wedge, bearing block, two shaft hydraulic cylinder and forming near switch etc.; Cast-in-block turns over the steel body and connects with wedge with swinging axle, and hydraulic cylinder piston rod one end connects with bearing pin with swinging axle, and the piston rod other end is equipped with near body, and the installing plate of placement near switch is housed on hydraulic cylinder body; Swinging axle and hydraulic cylinder all are installed in the bearing block that is fixed on cut somebody's hair body or the drawing head body.During work, send the signal of telecommunication by operating desk, make Hydraulic Station output services pressure oil, driving two respectively by two hydraulic cylinders turns over the steel body and rotates in the same way with the centre of gyration of swinging axle, thereby force the rhombus base to turn over the upset of slip limit, steel body surface limit two, when the rhombus base erects when having turned over,, hydraulic cylinder is quit work by sending the signal of telecommunication near switch.

The utility model compared with prior art has the following advantages:

1, simple in structure: turning over the steel body only is a foundry goods, not device such as the section of picking out and support wheel and track.

2, connect reliably: turn over the steel body and adopt wedge to connect with swinging axle, avoided Bolt Connection and locking device thereof, this connects closely reliable, easy accessibility.

3, easy to operate: the tilting gear structure is installed on the manipulator, and is nearer apart from roll, is convenient to the rhombus base and aims at pass.

4, multiple functional: regulate near the position of the switch, turning arbitrarily angled rhombus base, when the nearly switch of many windings is housed, multiple angles rhombus base simultaneously can overturn.

The utility model will further specify in the accompanying drawing of the following example.

Fig. 1 is a tilting gear structure structure chart;

Fig. 2 is tilting gear technology arrangement figure;

Fig. 3 is the another position of rhombus base that is different from Fig. 1.

In tilting gear structure structure chart shown in Figure 1, two turn over steel plate 1 steel-casting with rhombus base 13 directly contacts for having sufficient intensity and wearability, its contact surface is smooth, have radian, reverse side has a square hole body, so that swinging axle 4 inserts, they connect with all adopting monolateral wedge 2 connecting of swinging axle 4, the diaxon bearing 3 of swinging in the cross rest axle 4 or with cut somebody's hair body 11 or link with drawing head body 12, the working solution cylinder pressure is two shaft constant speed hydraulic cylinders 7, be installed on the bearing block 6 that is fixed on cut somebody's hair body 11 or the drawing head body 12, hydraulic cylinder piston rod one end connects with swinging axle 4 usefulness bearing pins 5, and the piston rod other end is equipped with near body 9, and the installing plate 10 that can place the nearly switch 8 of many windings is housed on this end cylinder body, have kidney shape hole on the installing plate 10, so that adjust position near switch 8.

In tilting gear technology arrangement figure shown in Figure 2, tilting gear is by operating desk 17, power cabinet 16, compositions such as Hydraulic Station 15 and tilting gear structure 14, tilting gear structure 14 is placed on respectively on cut somebody's hair body 11 and the drawing head body 12, when the rhombus base 13 of the position as shown in Figure 1 of overturning, operating desk 17 sends the signal of telecommunication, the hydraulic oil that has an operating pressure by 15 outputs of power cabinet 16 control Hydraulic Stations drives hydraulic cylinder 7 work in the tilting gear structure 14, the piston rod of hydraulic cylinder 7 drives swinging axles 4 by bearing pin 5 and clockwise rotates around self gyroaxis, turns over steel plate 1 upset thereby drive.The frictional force that the turning torque of turning over steel plate 1 overcomes rhombus base gravity and rhombus base when sliding on turning over steel plate 1 etc. produces the moment of resistance, makes 13 upsets of rhombus base.When rhombus base 13 is translated into desired location, near sending the signal of telecommunication hydraulic cylinder 7 is quit work near body 9 near switch 8.The flip angle that turns over steel plate 1 changes and can realize near the position of switch 8 by regulating.When rhombus base during, drive swinging axles 4 by hydraulic cylinder 7 and rotate counterclockwise the upset that realizes rhombus base 13 in position shown in Figure 3.

Claims

1, a kind of by operating desk, the power cabinet, the blooming mill that Hydraulic Station and tilting gear structure are formed is with rhombus base tilting gear, it is characterized in that the tilting gear structure is by turning over steel body 1, swinging axle 4, wedge 2, two shaft hydraulic cylinder 7 and forming the rhombus base of its turning any angle near switch 8 etc.
