Abstract
The utility model discloses a roll gap adjusting device, and belongs to the technical field of rolling equipment. The roll gap adjusting device is used for adjusting a roll gap of a finish rolled delivery roll of a high speed wire. The technical scheme includes that the roll gap adjusting device is composed of a fixing block, an adjusting bolt and a locknut. A threaded hole matched with the adjusting bolt is formed in the fixing block. The locknut is screwed on the adjusting bolt and arranged between a nut of the adjusting bolt and the fixing block. A locating groove is formed in one side of the fixing block and parallel to the axial direction of the threaded hole of the fixing block. The width of the locating groove is matched with the diameter of an air cylinder bolt on the top portion of an air cylinder. According to the roll gap adjusting device, roll gap adjusting manner is replaced by controlling of route adjustment of the air cylinder. Adjustment of the roll gap is accurate, stable and reliable. Stable and durable clamping force is obtained by a rolled piece in the process of delivery. Rolling speed, matched with rolling mills in a front area and a rear area, of the rolled piece is obtained, and therefore steel accumulating and steel wasting accidents caused by change of flow per second are reduced. The roll gap adjusting device has the advantages of being simple in structure, convenient and firm in installation, simple to change, simple in operation of the roll gap adjustment, good in effect and notable in economic effect.
Description
Technical field
The utility model relates to a kind of high-speed wire finish-rolling conveying roller roll gap adjustment device, belongs to the rolling equipment technical field.
Background technology
All cold-heading, spring, bearing and the high-level steel grade of steel cord are included in product mix in the Advanced Equipment high-speed wire production line at present, range of product size is 5 ~ 25mm, 6 ~ 7 sections water-cooled sections that rolling line is furnished with mm finishing mill unit, reducing sizing mill group and arranges in the middle of it, such arrangement form is so that the front conveying roller effect of finish rolling is particularly crucial.Conveying roller has two functions before the high line finish rolling: the one, and when rolling small dimension wire rod, if there is the heap steel, pinch the rolled piece to 800 that runs groove after the pre-finish rolling and shred disconnectedly, can reduce and run the rolled piece of leaving in the groove, reduce break down time, improve operating rate.The 2nd, when the rolling large-size wire rod, the clamping workpiece front end is entered smoothly subtract precision mill, because the empty mistake of mm finishing mill unit under this production model, rolled piece is longer to the range ability that subtracts precision mill from pre-finish rolling, the effect of pinch roll is quite important, if head pinches untimely or clamping loosening, will cause the cover that rises of rolled piece to pile steel; If the clamping tension causes shape of rolling piece to change, cause surface quality defect, even cause heap steel when nipping.
The conveying function that can conveying roller realize ideal depends on directly whether the setting of roll gap is accurate, whether duty is stable, but because the roll gap adjustment device position in the former design is in the bottom of equipment, it is again retaining thread hole on the equipment, adjust quite effort, and because constantly being subject to the power of bouncing in the middle of the use procedure, fixture on the equipment is damaged, can't use, cause the quite a while, the conveying roller function is lost substantially, brings great loss to production, and this problem has become the bottleneck problem that restriction is produced.
The utility model content
Technical problem to be solved in the utility model provides and can make the roll gap adjusting reach accurate, stable, reliable roll gap adjustment device.
The technical scheme that solves the problems of the technologies described above is:
A kind of roll gap adjustment device, it is comprised of fixed block, adjustment bolt, locking nut, there are screw and adjustment bolt to be complementary on the fixed block, locking nut is spun on to be adjusted on the bolt, between the nut and fixed block of adjusting bolt, one side of fixed block has locating slot, the axially parallel of the direction of locating slot and the screw of fixed block, and the diameter of the width of locating slot and the bolt cylinder of cylinder head is complementary.
Above-mentioned roll gap adjustment device, the body of rod of the bolt cylinder of described cylinder head are embedded in the locating slot of fixed block, and the lower surface of the clamp nut of bolt cylinder is pressed on the upper surface of fixed block.
Useful result of the present utility model is:
The utility model changes the roll gap adjustment device mode into the stroke adjustment of control cylinder, be installed on the set bolt of its upper side cylinder, it is very convenient to regulate, avoided originally bearing the position of moment maximum, change the control cylinder position of stressed minimum into, the beating power that device is subject to significantly reduces, and be multiplied service life.Owing to the roll gap adjusting is accurate, stable, reliable, make rolled piece in course of conveying, obtain to stablize lasting chucking power, the mill speed of the regional milling train coupling in rolled piece acquisition and front and back, thus reduce heap steel, the steel scrap accident that produces because of the second flow variation.The utility model is simple in structure, easy for installation firmly, replacing is simple, the roll gap Adjustment operation is easy, respond well, and significant economic benefit is arranged.
Description of drawings
Fig. 1 is the total figure of pinch roll roll gap adjustment device assembling before improving;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is scheme of installation of the present utility model.
Mark is as follows among the figure: the roller before improving meets adjusting device 1, adjusts bolt 2, locking nut 3, fixed block 4, locating slot 5, clamp nut 6, cylinder bolt 7, cylinder 8.
The specific embodiment
The utility model is comprised of adjustment bolt 2, locking nut 3, fixed block 4.
Show among the figure that adjust bolt 2 and fixed block 4 and is connected by threaded engagement, locking nut 3 is threaded connection with adjusting bolt 2, screwing locking nut 3 can fix the high and low position of adjustment bolt 2 and fixed block 4, and the roll gap after the adjusting is fixed.
Show among the figure that a side of fixed block 4 has locating slot 5, the axially parallel of the screw of the direction of locating slot 5 and fixed block 4, the diameter of the bolt cylinder 7 at the width of locating slot 5 and cylinder 8 tops is complementary.The body of rod of the bolt cylinder 7 at cylinder 8 tops is embedded in the locating slot 5 of fixed block 4, and the lower surface of the clamp nut 6 of bolt cylinder 7 is pressed on the upper surface of fixed block 4.
The utility model is installed on the top of the adjusting cylinder 8 of equipment, uses cylinder bolt 7 and matches with fixed block 4 with locating slot 5, with clamp nut 6 whole roll gap adjustment device is fixed.
The utility model characteristics are the size of conveying roller roll gap by the distance realization of the pitch regulated cylinder stroke of rotation adjustment bolt 2, and the adjustment precision can be accurate to ± 0.2mm.The position of bolt 2 is adjusted in locking nut 3 lockings, makes roll gap stable, firm.Whole adjusting device is positioned at the top of equipment, makes daily Adjustment operation quite convenient, and in addition the bat that is subject to of adjusting device is herein significantly lowered energetically, and is multiplied the service life of device, and easy access and maintenance.
