Abstract

The utility model provides a hot-rolling finished round-bar entrance guide, which is designed to solve the problems in the prior technology that the interval between the guide rolls can not be adjusted at any moment when worked, and when the multi-size and small-lot stick mill-bars are produced, changing the entrance guide very often is required, adjustment is inconvenient, and the product cost is high. The utility model comprises a guide case which is positioned on a mill-bar entrance of the rolling mill machine, a pair of entrance hold boards which are positioned in parallel in the guide case, and two guide rolls which are positioned oppositely on the entrance hold boards. In the middle of the two hold boards on the guide case, the adjusting bolt is positioned which can adjust the interval between the two guide rolls. For the reasons that the interval between the rolls can be adjusted by adjusting the bolt conveniently, so the utility model can be adapted to producing multi-size and small-lot hot rolling round bar on a certain rolling mill machine, without changing the entrance guide often. The entrance guide with simple frame and low cost, and is convenient to install and remove, saving time and energy, improving the production efficiency, and reducing the cost of producing the multi-size hot rolling round bar.

Description

The guide and guard of hot rolled circular steel finished product inlet

Technical field

The utility model belongs to rolling machinery, specifically a kind of guide and guard that guide hot rolled circular steel finished product inlet.

Background technology

Produce the used inlet guide and guard of small rod finished product, adopt two kinds of forms of guide and guard of clamping plate slidingtype and rolling guide more.The slidingtype guide and guard are owing to exist sliding friction between round steel and the guide and guard, and the round steel finished surface easily scratches, and guide and guard clamping plate quick abrasion, the clamping plate of wearing and tearing need frequent the replacing, have strengthened production cost, and be now superseded substantially.

The present round steel finished product rolling guide that uses, because complex structure, cost is higher; Simultaneously, because the spacing of its Roll Collar can not onlinely be regulated at random, many at the hot rolled circular steel specification in producing, batch is little, rolling a plurality of kinds on a milling train, must carry out integral replacing continually to the inlet guide and guard, so just need to prepare a plurality of integral body inlet guide and guard that can adapt to the different size round steel respectively, make guide and guard cost height, and every replacing once all wants on-the-spot the adjustment that rolling guide is installed, it is time-consuming to require great effort, and work efficiency is low; Above-mentioned multiple factor makes the production cost of hot rolled circular steel high for a long time.

The utility model content

Technical problem to be solved in the utility model is, overcoming existing Roll Collar spacing of producing hot rolled circular steel finished product rolling guide can not onlinely regulate at random, production specification is many, in batches during little bar, want the inlet guide and guard of frequent integral replacing round steel, change back adjustment trouble is installed, cause the high shortcoming of production cost, the guide and guard of a kind of hot rolled circular steel finished product inlet are provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the guide and guard of hot rolled circular steel finished product inlet comprise the guide cage that is installed in round steel finished product porch on the milling train, a pair of clamp type entry guide of parallel relative installation in guide cage, and be installed on the clamp type entry guide, two Roll Collars that roll surface is relative, the centre of two clamp type entry guides on guide cage is fixed with the pin of adjustable two Roll Collar spacings.

The utility model also has following technical characterictic:

The adjustment of described Roll Collar spacing is the nearly milling train arrival end on a pair of clamp type entry guide in guide cage, and supporting is equipped with two relative Roll Collars of roll surface respectively; One end of pin is fixed on the guide cage, and the other end is inserted in the centre of two clamp type entry guides; At the side elevation two ends of guide cage outer wall, with the lateral surface corresponding position of two clamping plate, the adjusting bolt that can withstand on two clamping plate lateral surfaces is installed;

Relative pin place on described two clamping plate is provided with concave arc respectively, and pin is inserted in the middle of two concave arcs;

On the roll surface of described Roll Collar, the deep-slotted chip breaker that can adapt to the round steel periphery is arranged.

During use, rotate the adjustment bolt of any end on the guide cage, two clamping plate promptly can be the close or separation of fulcrum one end with the pin, and the other end then with separation or close in the other direction, is regulated the size between two Roll Collars, satisfies the round steel production of multiple different size.

Advantage of the present utility model and good effect are, because the Roll Collar spacing of milling train inlet guide and guard can be adjusted easily with adjusting bolt, can fit the hot rolled circular steel of many specifications, small lot produces on a milling train, do not need integral replacing is continually carried out in the guide and guard that enter the mouth, do not need to make the inlet guide and guard that can adapt to many specifications yet, reduced production cost; If Roll Collar grown when needing repairing service time, unscrew and adjust bolt and two clamp type entry guides can be taken off online replacing in the lump together with Roll Collar, laborsaving saving time, the work efficiency height greatly reduces the production cost of hot rolled circular steel.Above-mentioned inlet guide and guard are simple in structure, cheap, and easy accessibility through measuring and calculating, to produce 150000 tons of calculating of round steel per year, uses the guide and guard of the utility model inlet compared with prior art, can save more than 30 ten thousand yuan every year.

Fig. 2 is the vertical view of the broken section of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, the guide and guard of hot rolled circular steel finished product inlet, comprise the guide cage 2 that is installed in round steel finished product porch band guide and guard bearing 7 on the milling train, a pair of clamp type entry guide 1 of parallel relative installation in guide cage 2, and be installed on the clamp type entry guide 1, two Roll Collars 6 that roll surface is relative, the centre of two clamp type entry guides 1 on guide cage 2 also is fixed with the pin 4 (referring to Fig. 2) of adjustable two Roll Collars, 6 spacings.

The adjustment of described two Roll Collars, 6 spacings is nearly milling train arrival ends on two clamp type entry guides 1 in guide cage 2, is respectively equipped with a pawl 1.1 up and down, between two pawls 1.1, be supported with guide roller axis 5 with bearing, two Roll Collars 6 that roll surface is relative are installed in respectively on the axle journal of guide roller axis 5.One end of pin 4 is fixed on the roof of guide cage 2, perhaps be fixed in the guide cage 2 below, the other end is inserted in the centre of two clamp type entry guides 1; At the side elevation two ends of guide cage 2 outer walls, with the corresponding position of two clamp type entry guides, 1 lateral surface 1.3, the adjusting bolt 3 that can withstand on two clamping plate lateral surfaces is installed.

For make two clamp type entry guides 1 when adjusting not to the positioning of the two ends of guide cage 2, relative pin 4 places are provided with concave arc 1.2 respectively at the middle part of described two clamp type entry guides 1, pin 4 is inserted in the middle of two concave arcs 1.2.

When contacting with the round steel surface, do not damage the round steel surface, on roll surface, be provided with the annular deep-slotted chip breaker 6.1 that can adapt to the round steel outer surface for the roll surface that makes two Roll Collars 6.
