Description

Novel guide nose tip installation structure

Technical Field

The utility model relates to a novel guide and guard nose tip mounting structure belongs to steel rolling guide and guard technical field.

Background

The steel rolling is a pressure processing process for obtaining a steel ingot and a steel billet with a required shape or improving the internal quality of steel and changing the shape of the steel ingot and the steel billet between rotating rollers, and along with the development of a steel rolling technology, the steel rolling technology and the process tend to be mature and stable at present, and how to promote new products on the basis of an original structure and the process and improve the cost, the technology and the like is necessary. Most of the inlet guides and guards for finish rolling have the following characteristics when assisting the red blank to enter the rolling mill: high speed, large impact force and the like, so the requirement on key stress parts of the inlet guide and guard is high. In the prior art, the guide nose tip is connected with the guide box body in front in an up-down embedded welding mode, and meanwhile, the joint of the guide nose tip and the guide box body adopts right-angle transition, so that the problem that the joint of the guide nose tip and the guide box body is broken exists.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a novel guide and guard nose point mounting structure, can guide and guard and eliminate nose point fracture problem to guarantee that the production operation is stable.

In order to solve the technical problem, the utility model adopts the technical scheme that:

the utility model provides a novel guide and guard nose point mounting structure, includes guide and guard nose point and guide and guard box body, be provided with the guide pulley in the guide and guard box body, guide and guard nose point rear side is opened and is equipped with four bolt holes, four the bolt hole is at upper and lower and left right direction symmetric distribution, guide and guard box body front side open be equipped with four with the mounting hole that the bolt hole position corresponds, the bolt passes screw in behind the mounting hole in the bolt hole, on the guide and guard nose point with guide and guard box body junction upper and lower direction is provided with the radius angle respectively.

The guide box body is provided with a lifting lug.

The radius of the fillet is 14mm.

The bolt is a hexagon socket head cap screw.

The diameter of the hexagon socket head cap screw is 10mm.

The guide nose tip is made of 2Cr13.

The utility model has the advantages that: the utility model provides a pair of novel guide and guard nose point mounting structure changes into the fixed mode of hexagon socket head cap screw four-point fastening and leads and guards the nose point and lead and defend the box body junction and change into the radius angle back by original right angle transition by original upper and lower embedded welding, can eliminate the nose point basically with the cracked problem of box body junction, can effectively improve the steel rolling and lead and defend when appearing piling the steel of abnormal situation because of the key atress position that rolling process's supplementary red steel got into the impact force of rolling mill causes greatly, guarantee that production operation is stable.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and the following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 and fig. 2, the utility model provides a novel guide nose tip mounting structure, which comprises a guide nose tip 3 and a guide box body 1, and the guide box body 1 is provided with a lifting lug. The guide wheel 2 is arranged in the guide box body 1, the guide nose tip 3 and the guide wheel 2 are on the same central line, and the red blank sequentially enters the guide box body 1, the guide wheel 2 and the guide nose tip 3. At least four bolt holes are formed in the rear side of the guide nose tip 3, and in the embodiment, the number of the bolt holes is preferably four. Four bolt holes are symmetrically distributed in the vertical and horizontal directions, four mounting holes corresponding to the positions of the bolt holes are formed in the front side of the guide box body 1, the bolts 4 penetrate through the mounting holes and then are screwed into the bolt holes, the guide nose tip 3 is connected and mounted at an outlet of the guide box body 1, and the height, the level and the centering performance are consistent. The utility model discloses change four point fixation into by two point fixation modes to measure and calculate the dynamics that rolling in-process nose point received the red base and assaulted, calculate fixing bolt's directness. In the present embodiment, the bolt 4 is a hexagon socket head cap screw having a diameter of 10mm. Meanwhile, original right-angle transition is changed, fillets 31 are respectively arranged in the vertical direction of the joint of the guide nose tip 3 and the guide box body 1, the radius of each fillet 31 is 14mm, the transition position between the joint of the guide nose tip 3 and the guide box body 1 is widened, and the capacity of bearing impact stress can be improved.

Meanwhile, the heat-resistant steel of the guide nose tip 3 is improved to be 2Cr13, the wear resistance is increased, the angle of the nose tip is changed when the red blank head enters the nose tip due to abrasion, the phenomenon of increasing the received impact force is delayed, and the possibility of breakage of the nose tip is effectively reduced.

To sum up, the utility model provides a pair of novel guide nosetip mounting structure, the fixed mode of hexagon socket head cap screw four-point fastening and guide nosetip and guide box body junction change the radius angle back into by original right angle transition, can effectively improve the steel rolling and lead to defend the key atress position that causes greatly because of the impact force of rolling process's supplementary red steel entering rolling mill when the heap steel of abnormal situation appears, guarantee that the production operation is stable.

The above are only preferred embodiments of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, a plurality of modifications and decorations can be made, and these modifications and decorations should also be regarded as the protection scope of the present invention.
