Abstract

The utility model belongs to an improvement of a stopper structure of a P/F wire of a high speed steel rolling wire rod, in particular to an improved stopper of the P/F wire of the high-speed wire rod, comprising a inserting slot which is composed of pressure plates fixed by bolts on a concave platform of a stopper body, wherein an inserting plate is arranged in the slot; a roller wheel is arranged on the inserting plate by bolts; a thickened boss is arranged at the top surface of the inserting plate which is matched with the inserting slot; a bearing is arranged in a bearing mounting hole which is positioned in the lower end of the roller wheel; and the roller wheel provided with the bearing is arranged on the inserting plate by bolts. In the improved stopper of the P/F wire, the roller wheel has a rational structure, the lubricating is good, the wearing is difficult, and the bending strength of the inserting plate is high, so that the bending deformation can be prevented, the offset of a travelling track and the clamping and blocking of the inserting plate can be avoided, the thermal shutdown default time can be reduced, the service life can be prolonged, and the maintenance load of equipment can be lowered.

Description

Improved high-speed rod P/F line stopper

Technical field

The utility model belongs to the improvement of steel rolling high-speed rod P/F line stopper structure, particularly improved high-speed rod P/F line stopper.

Background technology

Steel rolling high-speed wire factory P/F line has 28 stoppers, mainly is distributed in collection volume station, prunes sampling place, baler, weighs, unloads volume and all the other key areas of P/F line.The structure structure of stopper mainly contains plate, roller, pressing plate and stopper body and forms; The stopper roller connects with plate through attachment bolt; Attachment bolt is the hexagon-headed bolt of M22 * 65, and roller size is ∮ 115 * ∮ 22 * 34, and plate thickness is 12mm.Stopper is realized open and close through cylinder control, realizes an open closed cycle in 1 minute.Effect and the function of stopper in the P/F line is: stopper and impulse sender combination, through programed interlocking control, realize stop, the walking of C type hook.When previous impulse sender receives closure signal; The stopper in back is opened through cylinder, and the C type is hooked under the driving of P/F line and moves ahead, after impulse sender, the control program in its contact the place ahead obtain signal; The stopper of back is opened through cylinder, realizes the open and close of stopper successively.Original stopper roller connects with plate through attachment bolt; Though bolt, roller and plate endoporus have carried out lubricated oiling when mounted greatly because of sliding and running in the plate running causes frictional resistance; But it is more serious that it still weares and teares, just can not use because of serious wear less than 3 months, and in the open and close motion; Because of causing run trace skew after the wearing and tearing, usually with the generation of phenomena of the failure such as plate jam.Original stopper plate thickness is 12mm, and because of the plate thinner thickness, its bending strength is low, the frequent open and close of plate; Plate flexural deformation takes place often, and plate is jam in stopper, causes equipment fault, directly causes to produce to interrupt; Each these faults of handling all need be removed pressing plate, when the follower bolt dismounting is not fallen; Just need plate be prescinded with the oxyacetylene metal-cutting instrument, finish to processing from the beam worker utensil and resume production, the minimum time spent is more than 30 minutes.Accumulate when too much in case the serious and back C type hook of plate jam takes place, also can in case this fault takes place, dispose at every turn and resume production minimum 2 hours with the generation of carrying the rail metaboly.The frequent generation of these faults has not only brought very big influence to production, and causes and safeguard that intensity is big, cost consumption is bigger.

Summary of the invention

The purpose of the utility model is to provide a kind of improved high-speed rod P/F line stopper, and its roller structure is reasonable, and is lubricated good; Not easy to wear, the bending strength of plate is high, can prevent flexural deformation; Prevent the fault of run trace skew and plate jam; Reduce warm shutdown fault time, increase the service life, reduce maintenance of equipment work amount.

The purpose of the utility model is achieved in that a kind of improved high-speed rod P/F line stopper; Be included in that the pressing plate through bolt constitutes slot on the concave station of stopper body; Through slot plate is installed, on plate, roller is installed, the boss of thickening is being set on its end face of the plate that matches with slot through bolt; In the bearing mounting hole that on the lower surface of roller, is provided with bearing is installed, the roller that bearing will be housed through bolt shaft is installed on the plate.

The improvement of the utility model roller structure.The defective of original stopper motion connecting mode mainly is that roller and attachment bolt are relative sliding motion; The bottom surface of roller directly contacts with attachment bolt; The resistance of motion is quite big; Roller endoporus, roller bottom surface, attachment bolt easy abrasion, service life is very short, and the lubricant effect of bolt, roller and plate endoporus is relatively poor.Therefore, decision is utilizing former roller that the deep groove ball bearing of model for 6305-2z is installed therebetween, and its dimensions is ∮ 25 * ∮ 62 * 17, is being lubricated when refueling, and adds lubricating grease, operating aspect after the Sealing shield ring of bearing both sides is pried open.Carry out this improvement, only need on original roller, to carry out reaming, easy to process, can satisfy again and improve the needs that require, reach produced on-site.

The improvement of plate fault of construction.The major defect of plate structure is that former design plate thickness is 12mm, and the cross section is a rectangle, and because of the plate thinner thickness, its bending strength is low, and plate flexural deformation takes place the frequent open and close of plate often, the defective of plate jam in stopper.According to the on-site maintenance experience, decision changes the cross section of plate into the T type by rectangle, improves the bending strength of plate with this.

After the improvement, the utility model roller structure is reasonable, and is lubricated good, not easy to wear; The bending strength of plate is high, has prevented flexural deformation, has prevented the fault of run trace skew and plate jam; Reduce warm shutdown fault time, prolonged service life, reduced maintenance of equipment work amount.
