Abstract
The utility model discloses a split type combined guard nozzle, which comprises a shovel nozzle which is composed of an upper shovel and a lower shovel, wherein the shovel nozzle is fixedly connected with a connecting piece through bolts; the working face on the upper end of the upper shovel and the working face on the upper end of the lower shovel are respectively provided with a cambered face; the front end of the upper shovel and the front end of the lower shovel form into an arc-shaped angle; the front end of the upper shovel extends longer than that of the lower shovel. The utility model can separate a rolled piece from a roll, and steel blocking accidents are not easy to happen. After the shovel nozzle is broken, the shovel nozzle can be replaced; therefore, operating cost is reduced.
Description
Technical field
The utility model relates to a kind of guide and guards that applies to steel mill's rolling of sectional iron line, and it is a new construction in the guide and guards that mouth is defended in combination.
Background technology
Guide and guards is mounted in a kind of frock of continuous mill import and export, plays the effect of leading and escorting for rolled piece, and purpose is to guarantee the smooth steel of crossing of rolling process.Defending mouth is to prevent collaring, and rolled piece is derived roll smoothly.
Rolling of sectional iron used guide and guards in home and abroad often adopts monoblock type broad share mouth structure, and this device is put in the outlet of roll line roll, plays a part rolled piece is separated with roll.Mainly there is following shortcoming in this product:
1, shovel contacts with workpiece earlier under in the work, and the shovel of going up of guide and guard mid portion contacts with rolled piece then, and this is opposite with actual conditions in the work in proper order, can not fine rolled piece be separated with roll, and stifled steel takes place easily.
2, shovel is highly excessive at present in work, and during the work of shovel mouth, deformation of rolled wire is bigger, and the shovel mouth is stressed excessive, is difficult for rolled piece is separated with roll.
3, this shovel mouth width is identical with the rear portion, and the rolled piece width is narrower in using, and the shovel mouth inoperative roll that partly weares and teares has on the contrary reduced roll service life; Because shovel mouth width is excessive, reduced the quantity that roll is joined the roller groove, the roll utilization rate reduces.
4, these guide and guard are overall structure, and in use, in case wearing and tearing of shovel mouth or damage, these guide and guard are scrapped with regard to integral body, cause rolling cost to raise.
The utility model content
The purpose of this utility model provides a kind of split type combination and defends mouth, has overcome the shortcoming of prior art.
The technical solution of the utility model is as follows:
Mouth is defended in split type combination, includes the shovel mouth, is made up of last shovel and following shovel, and shovel mouth rear portion is a connector, it is characterized in that described shovel mouth and connector are the branch body structures, and the shovel mouth is fixed on the connector.
Mouth is defended in described split type combination, it is characterized in that the described shovel front end of going up extends beyond down outside the shovel.
Mouth is defended in described split type combination, it is characterized in that described upper and lower shovel front end becomes arc angle.
Mouth is defended in described split type combination, it is characterized in that the width of the width of described shovel mouth less than connector.
Mouth is defended in described split type combination, it is characterized in that shovel and the front end bottom working face that shovels down are cambered surface.
Compare with prior art, the utility model has following advantage:
1, changes and defend mouth by the situation in the real work after the shape, changed the engagement sequence of shovel mouth, contact earlier with rolled piece, rolled piece is separated with roll, shovel under then and contact with rolled piece again, rolled piece is thoroughly separated with roll by the shovel of going up of shovel mouth mid portion with rolled piece.When rolled piece just contacted with the shovel mouth, deflection was few, has reduced the suffered impulsive force of shovel mouth, improves the service life of shovel mouth.
2, the height of shovel and following shovel in the reduction, upper and lower shovel front end is an arc angle, makes rolled piece shortly past rolling centerline, the very fast shovel of going up is just started working, and at this moment the angle of collaring is very little, and the shovel mouth is easier to rolled piece and roll are peeled off, go up shovel simultaneously and adopt arc surface, increase shovel mouth intensity with shoveling front end down.
3, the shovel mouth has reduced shovel mouth width by the developed width design of rolled piece in the operation of rolling, and shovel mouth inoperative part and roll break away from will work, thus raising roll service life, and what also can increase roll joins roller quantity.
4, shovel mouth and connector adopt and divide body structure, adopt bolt (part 3), pad (part 4) to come fastening, rear portion connector (part 5) fully can be general, for different sorties, rolling products of different specifications, guide and guard only need be changed the shovel mouth portion, contiguous block is not fragile, can use for a long time, has reduced spare part quantity.In the operation of rolling, the shovel mouth portion is the most easy to wear, in case the wearing and tearing of shovel mouth only need be changed the shovel mouth portion, the weight of shovel mouth portion only is about 1/3 of whole guide and guard weight, thereby greatly reduces the steel rolling guide cost.
Description of drawings
Fig. 1 is the guide and guards of monoblock type broad share mouth structure.
Fig. 2 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, Fig. 2.
The utility model is made up of shovel mouth and connector, the shovel mouth is made up of last shovel 1 and following shovel 2, shovel mouth and connector 5 are for dividing body structure, the shovel mouth is fixedly mounted on the connector 5 by bolt (part 3), pad (part 4), last shovel 1 is a cambered surface with the front end working face that shovels 2 down, last shovel 1, shovel 2 front end camber angles down, on shovel 1 front end and extend beyond down outside the shovel 2.
Claims (5)
1, mouth is defended in split type combination, includes the shovel mouth, is made up of last shovel and following shovel, and shovel mouth rear portion is a connector, it is characterized in that described shovel mouth and connector are the branch body structures, and the shovel mouth is fixed on the connector.
2, mouth is defended in split type combination according to claim 1, it is characterized in that the described shovel front end of going up extends beyond down outside the shovel.
