Abstract
The invention relates to a lower mould mechanism for an ultra-large intelligent vertical hydraulic cold bending machine. The lower mould mechanism comprises a cuboid-shape mould body. The technical key points adopted by the invention are that the upper surface of the mould body is a semi-cylinder surface concaved downwards. The semi-cylinder surface is a supporting body of a bent steel pipe. A protection plate coated with a polyurethane protection layer is welded on the semi-cylinder surface. Three pairs of bending cylinder brackets are symmetrically welded on the two sides of the rear part of the mould body in pairs. Two pairs of lifting cylinder shafts perpendicular to the mould body in the axial direction are symmetrically arranged at the front part of the mould body. The bending cylinder brackets comprise side plates, inner plates and outer plates. The side plates are perpendicular to the mould body and are welded with the mould body. The inner plates and the outer plates are perpendicular to the side plates and are used for being in hinge joint with bending cylinders. The outer plates are screwed and fixed with the side plates by virtue of bolts. The structural design of the cuboid-shape mould body with the semi-cylinder surface, the bending cylinder brackets and the lifting cylinder shafts of the lower mould mechanism meets the requirement that in bending, the cambered surface is accurate, and the strength is high. Besides, when the bending cylinders breaks down, the cylinders can be dismantled by dismounting the outer plates, without jacking up a lower mould, so that the lower mould mechanism is convenient to maintain.
Description
Technical field
The present invention relates to bending machine and form mechanism, particularly a kind of ultra-large type Intelligent vertical hydraulic cold bending machine is used
Lower mechanism for tire.
Background technology
Since reform and opening-up, Chinese national economy fast development, within 2015, China's economic total volume has reached 67.67
Trillion (RMB), are sure to occupy second place of the world.But being as expanding economy, environmental pollution is the tightest
Weight, especially air quality index PM2.5 severe overweight, the area such as Beijing, North China, East China occurs in that sternly
The haze weather of weight.The data issued according to environmental science institute of Peking University show, China's air quality is up to standard
City only accounts for 2 one-tenth.Environmental pollution does not solve to have a strong impact on Chinese image, more can affect the step of reform and opening-up
Cutting down, therefore Party and government have resolutely formulated and have shut down, stop, merge and change, and thoroughly curb environmental pollution for coal with gas,
Solve the strategic decision of energy deficiency.Built natural gas transfering natural gas from the west to the east one, two, three lines for this, this year is i.e.
The most go into operation by transfering natural gas from the west to the east four line gone into operation and by the Sino-Russian gas transmission line of Heihe In The Heilongjiang River to Shanghai, and
Its main line pipe diameter is 1422mm, is the pipeline of the maximum caliber that China lays at present, " 13 "
End China long-distance oil & gas pipeline total kilometrage will be more than 160,000 kilometers.The main line of these emphasis pipeline engineering is built paving
During, pipe laying direction must be changed according to practical situation, in special location in pipeline construction,
Pipe factory often provides the elbow of standard degrees, but is not allow especially to spend with elbow in normal pipeline construction
The big elbows of number, because there being some construction equipments to work in pipeline, such as: line-up clamp, internal welding machine, clear
Pipe devices etc., therefore pipe bending curvature wants suitable, otherwise these construction equipments cannot work, additionally pipeline
Pipeline strength is also had an impact by bending curvature.This China's petrochemical industry is had relevant criterion: " On The Oil And Gas Transportation pipe
Road circuit engineering construction and acceptance specification " clear stipulaties pipe-line is constructed its radius of curvature in (SY0401-98)
>=40D (D is pipe diameter).Therefore develop one can at the construction field (site) steel tube bending be become radius of curvature >=
The large-scale intelligent bending machine of the different curvature of 40D, has important strategic importance.The mold mechanism of bending machine is certainly
Determine the bending curvature of pipeline, be the important component part of bending machine, but the lower mechanism for tire of existing mold has existed
Be not met by structure ultra-large type Intelligent vertical hydraulic cold bending machine for tube bending radian accuracy want
Ask.
Summary of the invention
The invention aims to provide a kind of intensity ultra-large type overhauled high, convenient solving the problems referred to above
The Intelligent vertical lower mechanism for tire of hydraulic cold bending machine, is effectively ensured the accuracy of tube bending radian.
The technical scheme is that
A kind of ultra-large type Intelligent vertical lower mechanism for tire of hydraulic cold bending machine, including carcass, described carcass is length
Cube shape and its upper surface are the semi-cylindrical of concave downward, described semi-cylindrical is welded with and is covered with polyurethane
The protective plate of overcoat, described carcass rear portion lateral symmetry is welded with three pairs of curved cylinder bearings, before described carcass
Portion is symmetrical equipped with the two pair lift cylinder axles axially vertical with carcass, described curved cylinder bearing by with carcass shafts
The inner panel for hinged curved cylinder vertical with side plate to side plate that is vertical and that weld and outside plate composition, institute
Stating outside plate utilizes bolt to fix with side plate twist-on.
Preferably, described carcass rear end is provided with a pair for the support ear hinged with backing roll.
Preferably, the quantity of described curved cylinder bearing is three right.
Preferably, the quantity of described lift cylinder axle is two right.
The invention has the beneficial effects as follows: the present invention matches with upper mechanism for tire and realizes the control of tube bending curvature,
The upper tire contacted with steel pipe during bend pipe is upper fulcrum, with curved cylinder to upper fulcrum for moment radius, and above tire
The hyperboloid of intrados is track deformation, and above tire lowest part deforms along its hyperboloid, backward along with bending
The rising of oil cylinder and change, the height that curved cylinder rises determines the size of bend pipe curvature.As bend pipe power
Supporting body, lower mechanism for tire of the present invention utilizes the structure design of curved cylinder bearing and lift cylinder axle completely
Foot intensity is high, cambered surface requirement accurately, meanwhile, when curved cylinder is faulty, without tire under jack-up with regard to energy
Oil cylinder is dismantled, it is simple to maintenance by pulling down outside plate.
