Description

Feeding roller way

Technical Field

The utility model relates to a feed roller belongs to steel ball production facility technical field.

Background

The steel ball is used as an ore grinding medium of the ball mill and is widely applied to ore grinding work of the ball mill. The ball mill is a main device in the mineral separation process and is widely applied to the mineral grinding process of a mineral separation plant. China is a large mineral mining country, and a large number of ball mills are used, so that a large number of steel balls are needed. The steel ball is a vulnerable part, and the annual consumption is very large. The forged steel balls are widely used at present due to long service life. The hot-rolled steel ball has the advantages of stable internal quality, compact metallographic structure, fine grains, difficult deformation, good wear resistance and the like, so the hot-rolled steel ball is widely used.

The conventional hot-rolled steel ball production process generally adopts the technical production of hot-rolled ball-milled steel balls of various specifications by using the ferrous metallurgy industry standard of forged (rolled) steel balls (YB/T091-2005), the diameter range of the steel balls is phi 25-125 mm, and blanks adopted by the rolled ball-milled steel balls are hot-rolled round steel rods with various chemical compositions, and the diameter of the blanks is equal to the nominal diameter of the steel balls; the main production process flow of the conventional hot-rolled steel ball is as follows:

firstly, after a round steel bar is inspected, shearing the round steel bar into a steel ball blank according to a fixed length;

step two, heating the steel ball blank to a proper temperature in a continuous heating furnace before rolling;

step three, after the hot-red billet is sent into a hot rolling mill, the hot-red billet rotates and advances between two rollers with special spiral hole patterns and is continuously rolled into steel balls;

step four, the rolled red hot steel balls immediately enter heat treatment equipment for quenching-tempering heat treatment, so that the steel balls obtain high and uniform hardness;

and step five, sending the qualified product to a finished product warehouse, packaging and sending the packaged product to a client.

At present, a feeding roller way is usually adopted to send the red hot billet into a hot rolling mill for rolling in the third step, and because the round steel rod is inevitably bent to a certain degree, the part of the rod which does not enter the rolling mill is violently shaken and even thrown out of the roller way in serious cases, workers standing beside the rolling mill are easily injured, and serious potential safety hazards exist; in addition, the existing feeding roller way is not provided with a material returning device, when the bending degree of the round steel bar is too large and can not meet the rolling requirement, the round steel bar needs to be manually lifted away from the roller way, the operation process is complex, and the production efficiency is reduced.

Compared with the prior art, the utility model has the advantages of:

1. the utility model relates to a feeding roller way, it can prevent effectively that the back end that the existing round steel bar material leads to because of having certain crookedness from producing the problem that acutely rocks or even bounces when rolling through setting up a flip above the feeding roller way, reasonable in design and convenient operation have improved the security of workman's operation;

2. the utility model relates to a feeding roller way, it sets up the material returned support in roll table one side, can overturn the too big round steel stick of bending degree to the material returned support through material returned arm on, realize the automation of material returned process, easy operation has reduced workman's intensity of labour, has improved production efficiency.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the feeding roller bed in this embodiment includes a frame 1, a plurality of guide rollers 2 are arranged in parallel from left to right on the top of the frame 1, a flip cover 3 is arranged above the guide rollers 2, a plurality of flip cover cylinders 4 are arranged on one side of the frame 1, a flip cover cylinder tailstock 11 is arranged below the flip cover cylinders 4, ends of the flip cover cylinders 4 are hinged to the flip cover cylinder tailstock 11 through a flip cover cylinder lower pin 12, the flip cover 3 is provided with a plurality of connecting arms 19 on corresponding sides of the flip cover cylinders 4, middle portions of the connecting arms 19 are hinged to the frame 1 through a flip cover pin 9, and outer ends of the connecting arms 19 are hinged to piston rod ends of the flip cover cylinders 4 through a flip cover cylinder upper pin 10;
