The utility model has the advantages of no pollution, low cost, high production precision and long usage lift, which can be adopted in the cold continuous rolling mill, reversible rolling mill and pinch pass mill. The utility model can stepless adjust the rolling line, produce high precision cold rolling strip steel, replace the imported equipment on that, and speed up the rolling mill localization.

Description

4-roller cold rolling mill and planisher rolling line stepless adjusting apparatus

Technical field

The utility model relates to 4-roller cold rolling mill and planisher, relates in particular to a kind of 4-roller cold rolling mill and planisher rolling line stepless adjusting apparatus.

Background technology

Up to the present, the homemade 4-roller cold rolling mill that each big steel company of China uses substantially all is medium-sized, and promptly the wedge device is installed in the bottom of milling train.After but this equipment was installed in the bottom, working condition was abominable, adjusted low precision.Be lined with copper shoe between the wedge in the normal four-roller cold-rolling mill wedge adjusting equipment, in relative motion, adopt dry oil lubrication, pipe arrangement, complex structure, and drier oil is easy to drip and drops down strip surface, influences strip quality, do not have any backing plate in wedge bottom and back-up chock contact-making surface, wedge is worn easily, and the life-span is short.

Summary of the invention

In view of the above-mentioned deficiency of existing in prior technology, the utility model is intended to disclose a kind of 4-roller cold rolling mill and planisher rolling line stepless adjusting apparatus, its wedge balancing controls can accurately be determined the absolute altitude of stocking, and reduce and pollute, reduce production costs, raising equipment serviceability prolongs service life of equipment.

Technical solution of the present utility model is achieved in that

A kind of 4-roller cold rolling mill and planisher rolling line stepless adjusting apparatus, it is characterized in that its wedge balancing controls are located at the top of mill housing window, comprise wedge, descend wedge, go up the traversing cylinder of wedge, descend slide plate and wedge backing plate between the traversing cylinder of wedge, guider, wedge, described wedge backing plate is positioned on wedge bottom and the back-up chock contact-making surface, slide plate is positioned on the contacted surface of upper and lower wedge between described wedge, is to inlay solid self lubricant material in the base steel sled surface.

Described wedge backing plate is 38CrMoAl, and via nitride is handled its surface, back nitration case.

The utility model compared with prior art is essentially different; Its beneficial effect is conspicuous:

Adopt the base steel slide plate between wedge, and inlay solid self lubricant material on its surface, reduced the pollution of greasy dirt to band on the one hand, it is simple in structure on the other hand, need not pipe arrangement, and the consumption of copper alloy significantly reduces, thereby cost reduces greatly.

Increase the backing plate that two block of material are handled for the 38CrMoAl via nitride at the wedge bottom surface, improved the allowable stress of contact, when improving the degree of accuracy of adjusting absolute altitude, the life-span that has strengthened wedge.

The band steel that adopts the milling train of the technical solution of the utility model to produce has advantages such as thickness of strip is even, but production high accuracy cold-strip be applicable in tandem mills, reversable mill, the smooth unit, height of rolling line is carried out stepless adjustment.Its alternative import equipment, the localization process of quickening milling train.

Among the figure, 1, go up wedge 2, down wedge 3, go up the traversing cylinder 4 of wedge, slide plate 6, wedge backing plate 7, guider 8, back-up chock between the traversing cylinder 5 of wedge, wedge down.

The specific embodiment

The utility model is further described below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, wedge balancing controls of the present utility model oblique 2 by last wedge 1, hyposphene, go up the traversing cylinder 3 of wedge, down the traversing cylinder 4 of wedge, wedge tiltedly between slide plate 5, wedge backing plate 6, guider 7 form.Wedge is a symmetrical mechanism up and down, is positioned at the top of mill housing window; Last wedge 1 and following wedge 2 are promoted by the traversing cylinder 3 of wedge and 4 respectively or pulling is carried out laterally moving, and carry out the adjustment of rolling line absolute altitude, but cause the wedge wearing and tearing easily at wedge and back-up chock 8 contact areas, thereby make the adjustment precise decreasing.The utility model increases a backing plate 6 in wedge bottom and back-up chock 8 contact-making surfaces, delays wearing and tearing, and improves and adjust precision.Increase lower bolster 6, as shown in Figure 3 and Figure 4, its material adopts 38CrMoAl, and via nitride is handled, and has very high intensity and hardness, the wearing and tearing that in the time of can obviously reducing wedge and contact with back-up chock 8 wedge caused.

Fig. 5 and Fig. 6 are the part drawing of slide plate 5 between wedge in the utility model, between wedge, increase by two slide plates, the material of this novel slide plate is: " the FZ-base steel is inlayed ", its matrix is Q235-A, inlay solid self lubricant material on the slide plate face, do not pollute, and reduced the consumption of copper alloy, production cost reduces greatly.

Claims (2)
