Abstract

The utility model relates to a roller arranged on a rolling mill. The utility model is characterized in that the surface of the roller is opened with one track or multi-track of designs of sections discontinuously distributed along the direction of a circumference. The design of sections is matched with the uninterrupted design of sections of an ordinary roller to form a pair of design of sections. In the time of rolling materials, blanks are rolled into sectional materials with intermittent strings after entering and coming out of the designs of sections of the two rollers. The utility model resolves the problem that punching process is needed in the production of sectional materials with intermittent strings to produce end products in the existing technology. The utility model also has the advantages that the production efficiency is increased and the cost is reduced.

Description

Rolling mill roll

The utility model belongs to the milling train parts, particularly relates to the roll on a kind of milling train.

Milling train of the prior art generally comprises a plurality of rolls, these roll position roll systems.The surface of each roll has pass along roll circumference, the shape of pass is decided according to the section material section shape of need processing, one group of roll of the adjacent composition of per two rolls, their the pass processing pass that partners relatively adds the man-hour blank through being rolled into the section bar of required section configuration behind the processing pass of some breaker rolls gradually.Different section configurations can have different pass designs.For example: the pass of I-steel is an I shape, and the pass of channel-section steel is a grooved, and other comprises: angle steel, screw-thread steel etc. has nothing in common with each other.No matter but the roll of which kind of pass, their pass all is continual along the elongated layout in roll circumference surface, thus the section configuration of the section bar that goes out with this Roller Machining along section bar axial elongated be a kind of shape.Produce the section bar of the ribbed stiffener that interruption is arranged if desired, can only pass through stamping procedure again, go out to be interrupted muscle with punch ram.Technology is loaded down with trivial details, and production efficiency is low.

The purpose of this utility model provides a kind of rolling mill roll, after this rolling mill roll and the supporting use of existing roll, can directly roll out the section bar that is interrupted muscle.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of rolling mill roll on the roller surface, has at least one pass along the circumference of roll, it is characterized in that having at least in the described pass together distributing along the roll circumference surface discontinuities.

The pass that described interruption distributes at roller surface upper edge roll mandrel to multiple tracks is arranged.

At least two kinds of passes are arranged on the described roll, wherein have a kind of continual common pass at least.

To multiple tracks is arranged, the common pass of described uninterrupted distribution also has multiple tracks to the pass that described interruption distributes at roll mandrel.

The pass that described interruption distributes is to be interrupted the corresponding pit of muscle shape with section bar.

Described pit has together, and the uninterrupted common pass that distributes has together.

The common pass of described uninterrupted distribution is and the approximate accordingly T-shape of section material section shape.

The pass that described interruption distributes has twice at least, and the shape of per pass pass is different.

The pass of described uninterrupted distribution has twice at least, and the uninterrupted pass shape of per pass is different.Inequality.

Advantage of the present utility model: after using this roll stacks to dress up milling train, can directly roll out the section bar that is interrupted muscle by rolling mill practice, need not to pass through again Sheet Metal Forming Technology, production efficiency has increased substantially, reduced production cost, be suitable for requirement of industrialized batch production, can create better economic benefit.Simultaneously, the pass that the interruption on the roll distributes can have multiple tracks, can also use another road after having gone bad together.Simultaneously the multiple tracks on roll be interrupted the shape of pass can be different, to process the section bar that is interrupted muscle that has of different section shape, reached the effect that a milling train can process multiple section configuration shape material.

Below in conjunction with accompanying drawing the utility model embodiment is done to describe in further detail:

Fig. 1 is that the roller that comprises the utility model roll is a schematic diagram;

Fig. 2 is the front view of a kind of section bar of processing of the utility model;

Fig. 3 is the vertical view of a kind of section bar of processing of the utility model;

Fig. 4 is the profile of a kind of section bar of processing of the utility model;

Fig. 5 is the structural representation of the utility model roll;

Fig. 6 is the profile of the utility model roll;

Fig. 7 is the local enlarged diagram of the utility model roll A portion;

Fig. 8 is the local enlarged diagram of the utility model roll B portion;

As shown in Figure 1: milling train comprises that roller system, roller system are made up of some rolls.Some common rolls 2 and at least one the utility model roll 1 are wherein arranged, and the interruption pass of roll 1 is relative with the pass of common roll 2, and cooperation partners.Roll of the prior art all is common rolls 2.The milling train that these common rolls 2 are assembled into can not directly roll out the shaped steel that is interrupted muscle.Need just can produce the shaped steel that is interrupted muscle through Sheet Metal Forming Technology.As Fig. 2, Fig. 3, shown in Figure 4.There is a kind of roll of pass can roll out the upright fence post 3 of cross band discontinuities muscle 4 in the roll that the utility model comprises.Certainly, leave other interruption distribution pass on the roll, also can roll out the shaped steel of other section configuration.

As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, can offer twice on the utility model roll and be interrupted pass 5.Also can offer more multiple tracks.Can also have on this roll together or the uninterrupted pass 6 of multiple tracks more.

Operating process:, be assembled into milling train the supporting position roll of this roll and common roll of the prior art system.This roll is adjacent with another common roll, the roll that partners, and the common pass that this breaker roll is interrupted on pass and the common roll partners.After material is by this breaker roll, can roll out the interruption muscle at material surface.
