Description
Technical field
The present invention relates to rod hot rolling equipment technical fields, more particularly to a kind of to be used for stainless steel and alloy steel bar product
The bar high-precision rolling mill of hot rolling.
Background technology
The steel rolling equipment of most domestic iron company Bar Plant is usually to be introduced from foreign countries, mainly there is Italian pomini
Company and the two-roller mill of danieli companies, the country are referred to as " short stress path rolling mill ", i.e. non-stand rolling mill.This milling train
Because simple in construction, easy to disassemble and assemble, it is widely adopted；Both horizontal mill use can be done, vertical mill use can also be done.And bar
Hot rolling is usually to go out finished product pole on vertical mill, but product size precision is difficult to control, and ovality deviation is larger.To solve this
Problem, some producers increase " reducing sizing mill " or " rule circular knitting machine " to realize after last rolling mill.But its structure is complex, working service
Difficulty, operating cost is higher, and involves great expense.
Below by taking existing Italy's pomini milling trains as an example, by its structure and there are problems to be described below：
With reference to Figure 1A, Figure 1B and Fig. 1 C, this milling train assembling bind mode is, by four bearings 18 for roller being fastened protrusion
After being assembled with pedestal 16, respectively it is locked by one big cylindrical bolt 10；Referring next to Fig. 1 D and Fig. 1 E, pedestal 16 and bearing
It is positioned between 18 by positioning key 12；In this way, there are 1-2mm fit-up gaps between pedestal 16 and bearing 18.With daily
Using frequent dismounting, gap can further increase.This milling train uses still as horizontal mill, when as vertical mill in use,
Since more than fit-up gap exists, referring to the gap S in Fig. 1 F, add upper roller system dead weight and rolling axial force, single branch just has occurred
Above and below roll the phenomenon that play, bounce amplitude can reach 2-3mm.So the pole of rolling is oval, it is impossible to meet production
The specification requirement of product.
Invention content
For the problems of the prior art, the present invention proposes a kind of bar high-precision rolling mill, can be processed to avoid bar
Axial runout in journey, high precision machining.
To achieve the object of the present invention, bar high-precision rolling mill of the invention includes pedestal and roller system, and the roller system leads to
It crosses roller system bearing to fix with floor installation, the column of the rolling mill base is equipped with conical bore and four grooves, the groove
It is interior to be equipped with adjustment liner plate；Four sides of roller system bearing are equipped with vertical convex with four fit depressions on rolling mill base column
Platform structure can adjust the fit-up gap between roller system bearing and pedestal upright post by adjusting liner plate housing pin；It is described
The conical bore being equipped on semicircle taper hole, with rolling mill base column among the boss of roller system bearing matches, and pass through cone
Wedge bolt locks roller system bearing and rolling mill base.
The bar high-precision rolling mill of the present invention, close structure, dismounting are simple；Rigidity is high, and bouncing value is small, no axial float,
By the pole product of this mill milling, sectional dimension precision is high, and ovality is small, and particularly suitable bar production uses；This milling train
Production domesticization high-volume manufacture can replace import completely, have huge economic and social benefit.

Specific embodiment
With reference to attached drawing, details are as follows for structure feature of the invention and advantage.
Referring to the general assembly figure structure schematic representation of the milling train of the present invention shown in Fig. 2A, 2B and 2C, bar high-precision
Milling train includes pedestal 20, and roller system 30, the roller system 30 is fixed by bearing 32 with floor installation, together with reference to figure 3A, 3B and 3C.
The column 21 of the rolling mill base 20 is equipped with conical bore 201 and four grooves 22, and adjustment liner plate 202 is equipped in groove 22；
Referring to Fig. 4 A, 4B and 4C, four sides of roller system bearing 32 are equipped in upright shoulders structure 302, with rolling mill base column 21
Four grooves 22 match, as shown in Figure 2 B, and the position of adjustment liner plate 202 is adjusted to eliminate by adjusting housing pin 24
Fit-up gap；201 phase of conical bore being equipped among the boss of roller system bearing 32 on semicircle taper hole 301, with rolling mill base column
Match, and pass through conical wedge bolt 26 and lock.
In the above embodiments, on the one hand, boss structure on the column of rolling mill base is set and is set on roller system bearing
The groove coordinated with it is put, liner plate and adjusting screw is coordinated to adjust fit-up gap between the two；On the other hand, in milling train
Conical bore in pedestal upright post is set and matched semicircle taper hole is set on roller system bearing, it is ensured that position essence during equipment
It spends and is fastened the two by conical wedge bolt；In this way, roller system and pedestal can be tightly linked integrally, between do not deposit
In a gap, even if in rolling on edge state, will not occur due to caused by fit-up gap above and below some roll the phenomenon that play,
It ensure that the rolling accuracy of bar, the rolling on edge status diagram of the milling train of the present invention shown in Figure 5.
The bar high-precision rolling mill close structure of the present invention, dismounting are simple；Rigidity is high, and bouncing value is small, no axial float, leads to
The pole product of this mill milling is crossed, sectional dimension precision is high, and ovality is small, and deviation is not more than ± 0.2mm.The present invention is state
Inside and outside steel industry is initiated, and particularly suitable bar production uses.Promoting the production domesticization high-volume manufacture of this milling train can replace completely
Import has huge economic and social benefit.
The present invention is not limited to the described embodiments, and those skilled in the art is i.e. public in the spirit for not departing from the present invention
It in the range of opening, still may make some modifications or changes, therefore the scope of the present invention is limited ranging from claims
It is accurate.
