Abstract
The utility model relates to a rod rolling apparatus, in particular to a 45 degrees top cross rod rolling mill hermetic sealing device, aiming to solve the problem that the current seal is easy to fail, lubricating oil is polluted because iron scale is brought by cooling water to enter into the rolling box, thereby the normal work of the mill is influenced. The technical proposal of the utility model is that a groove is arranged between an abrasion-resistant eyeglass plate (1) and an oil throw (8) and is filled with high pressure gas, hereby a gas chamber is formed between the abrasion-resistant eyeglass plate and the oil throw; the high pressure gas is leaked from the clearance between an upper slip ring and the oil throw, forming a gas shield which effectively prevents cooling groove water from entering in the gas chamber. By the high pressure gas, an upper lip edge of a rubber seal is kept to cling to the upper slip ring. The utility model is characterized by reasonable structure, convenient improvement and improved sealing effect.
Description
Technical field: the utility model relates to a kind of wire rod rolling equipment, particularly 45 ° of topcross wire mill gas sealing mechanisms.
Background technique: at present, the high speed wire rod finishing block group often adopts 45 ° of types of topcross, and milling train divides roll-box and uni-drive gear box two-part, and the gear in the output gear of gear-box and the roll-box on the roll mandrel is meshed.The sealing of roll-box output shaft and casing is to realize by several parts that cooperatively interact: 1. be installed in the eye slab on the panel, 2. be installed in the eccentric oil thrower that matches with eye slab on the eccentric bushing, 3. be installed in the slip ring up and down on the axle, 4. be installed in the rubber seal between upper and lower slip ring on the oil thrower.In the work engineering, roll mandrel rotates with upper and lower slip ring, utilize two lip limits of rubber seal and slip ring be adjacent to and relative movement realizes that shutoff waters the iron scale that produces in the groove water and the operation of rolling and enter down in the milling train.This sealing means is very high to the requirement of rubber seal, and two lip limits must be adjacent to slip ring all the time, in case the heat ageing of being subjected to and wearing and tearing, to make seal failure, a large amount of rolling cooling water bands iron scale and is entered and roll in the case, causes lubricant pollution, influences the milling train proper functioning.
The purpose of this utility model provides a kind of 45 ° of topcross wire mill gas sealing mechanisms, changes sealing configuration, improves sealing effect, and effectively control is intake and kept the lubricant oil cleaning, solves the problems referred to above that prior art exists.
Model utility content: between the eye slab of 45 ° of topcross wire mills and oil thrower, groove is set, charge into pressurized gas, make and form air chamber between eye slab and the oil thrower, pressurized gas by last slip ring and oil thrower gap to external leakage, stoped effectively and watered entering of groove water, form gas shield one, rely on the effect of pressurized gas, make the upper lip of rubber seal and last slip ring keep being adjacent to.
Adopt the utility model, need not 45 ° of topcross wire mills are carried out big change, only eye slab and oil thrower are done very little modification, simple and easy to do, significant sealing affection in the working life of having improved rubber seal, has rational in infrastructure, characteristics such as improvement is convenient, raising sealing effect.
Description of drawings:
Fig. 1 is the utility model example structure schematic representation.
Fig. 2 is the utility model sealed air chamber structural representation.
Among the figure, eye slab 1, panel 2, eccentric bushing 3, roll mandrel 4, following slip ring 5, last slip ring 6, rubber seal 7, oil thrower 8, air chamber 9, grease chamber 10, gas circuit 11.
Embodiment: the gear in the output gear of milling train gear-box and the roll-box on the roll mandrel 4 is meshed, eye slab 1 is installed on the panel 2, eccentric oil thrower 8 matches with eye slab and is installed on the eccentric bushing 3, last slip ring 6 and following slip ring 5 are installed on the axle 4, rubber seal 7 is installed on the oil thrower 8, between upper and lower slip ring.Between the eye slab 1 of 45 ° of topcross wire mills and oil thrower 8, groove is set, air chamber 9 promptly is set on oil thrower 8, the both sides of air chamber are provided with grease chamber 10, gas circuit 11 is set on eye slab, gas circuit one end is communicated with air chamber, the other end is connected with source of the gas, pressurized gas enter air chamber by gas circuit, make gassy between eye slab and the oil thrower, pressurized gas, have been stoped effectively and have watered entering of groove water to external leakage by last slip ring and oil thrower gap, form gas shield one, rely on the effect of pressurized gas, make the upper lip of rubber seal and last slip ring keep being adjacent to.
Claims (2)
1, a kind of 45 ° of topcross wire mill gas sealing mechanisms, have eye slab (1), eccentric bushing (3), roll mandrel (4), following slip ring (5), go up slip ring (6), rubber seal (7), oil thrower (8), oil thrower matches with eye slab and is installed on the eccentric bushing, last slip ring and following slip ring are installed on the roll mandrel, rubber seal is installed on the oil thrower, between upper and lower slip ring, it is characterized in that between eye slab and the oil thrower groove being set, charge into pressurized gas, make to form air chamber between eye slab and the oil thrower.
2,45 ° topcross wire mill gas sealing mechanisms according to claim 1 is characterized in that air chamber (9) is set on the oil thrower (8), and gas circuit (11) is set on eye slab (1), and gas circuit one end is communicated with air chamber, and the other end is connected with source of the gas.
