Abstract

The utility model discloses a rolling guide device. The rolling guide device comprises a guide box body. Guide roller sets for conveying rolled pieces are arranged on the guide box body. The guide roller sets include the first guide roller set and the second guide roller set, wherein the first guide roller set and the second guide roller set are correspondingly arranged a left and right mode and fixed to two rotating shafts in a rotating mode. The first guide roller set and the second guide roller set are respectively composed of an upper guide roller and a lower guide roller, wherein each upper guide roller and the corresponding lower guide roller are arranged in a vertically-spaced mode. The ends, close to each other, of each upper guide roller and the corresponding lower guide roller are arranged to be in a conical shape with the roller body outer diameter gradually decreasing from the middle portion to the ends. According to the scheme, the first guide roller set composed of the corresponding upper guide roller and the corresponding lower guide roller and the second guide roller set composed of the corresponding upper guide roller and the corresponding lower guide roller convey the rolled pieces, and under the condition that the requirement for the diameter of each roller body is low, the phenomenon that small-diameter sections are formed after annular grooves are formed can be avoided, and the phenomenon that the roller bodies are broken due to friction between the rolled pieces and the roller bodies can be avoided.

Description

A kind of rolling guide

Technical field

The utility model relates to rolled piece conveying equipment field, is specifically related to a kind of rolling guide.

Background technology

In the rolled piece operation of rolling, for improving rolling efficiency, by arranging many group guide assemblies, realize multi-thread tandem rolling.The volume width of tradition guide and guard is large, is the guide and guard as much as possible of arranging in certain space, therefore, conventionally, by reducing the radial dimension of deflector roll, reduces the width of guide and guard.Although the method realizes arrangement guide and guard as much as possible to a certain extent, on roll line, deflector roll used is all generally the roll body that annular groove is offered at middle part, and deflector roll radially volume reduces, and the roll body diameter at annular groove bottom land place is just less.And guide and guard are led while carrying to rolled piece, the friction between rolled piece and roll body is large, and particularly to annular groove place, therefore, after date one section time is used in guide and guard, and the just easily fracture of deflector roll middle part causes stagnation and the security incident of whole production line.

Summary of the invention

The purpose of this utility model is to provide a kind of outlet rolling and leads position, and it can solve the problem that is easy to fracture after deflector roll diameter diminishes.

For achieving the above object, the utility model has adopted following technical scheme: a kind of rolling guide, it is characterized in that: comprise guide case body, on guide case body, be provided with the guide roller set that rolled piece is carried, guide roller set comprises that left and right corresponding layout rotate respectively first and second guide roller set being fixed in two rotating shafts, first and second guide roller set is respectively up and down and forms from the upper and lower deflector roll of arranging, the taper that body of roll external diameter is reduced gradually by middle part to end is arranged to respectively in the mutually close one end of upper and lower deflector roll.

First and second guide roller set consisting of upper and lower deflector roll in such scheme is carried rolled piece, can require, in less situation, to avoid forming diameter compared with segment after offering annular groove at roll body diameter, avoids the friction between rolled piece and roll body to cause roll body fracture.

Accompanying drawing explanation

Fig. 2 is the sectional view of the axis place plane of two rotating shafts in the utility model;

Fig. 3 the utility model is arranged the structural representation for multistrand rolling.

The specific embodiment

The purpose of this utility model is to solve in multistrand rolling the problem that is easy to fracture due to roll body diameter after diminishing.Its scheme of taking as shown in Figure 1, 2, a kind of rolling guide, it is characterized in that: comprise guide case body 10, on guide case body 10, be provided with the guide roller set that rolled piece is carried, guide roller set comprises that left and right corresponding layout rotate respectively first and second guide roller set 11 being fixed in two rotating shafts 12, first and second guide roller set 11 is respectively up and down and forms from the upper and lower deflector roll 111,112 of arranging, the taper that body of roll external diameter is reduced gradually by middle part to end is arranged to respectively in the mutually close one end of upper and lower deflector roll 111,112.In the utility model, guide roller set can be arranged on middle part or the tail end of guide case body 10, to adapt to the demand of different operations and operation, can be arranged with the supporter that keeps 111,112 spacing of upper and lower deflector roll in rotating shaft 12.Guarantee the spacing between upper and lower deflector roll 111,112, supporter can arrange separately, also can consist of the part on guide case body 10, and the setting of supporter should not exert an influence to the conveying of rolled piece.First and second guide roller set consisting of upper and lower deflector roll is carried rolled piece, position is led in the rolling forming like this can be according to arranging and carry out multistrand rolling as shown in Figure 3, what the diameter of roll body can be arranged is less, multiple rolling guides of arranging in the confined space as much as possible, after can avoiding again traditional roll body diameter to reduce, the friction easy and rolled piece of roll body annular groove section causes roll body fracture.The structure of the upper and lower deflector roll here, can be regarded as the roll body of offering annular groove by a middle part is split to form along annular groove middle part, and the cross section of annular groove can be triangle or semicircle.

During concrete operations, on, lower guide roll 111, the roll surface of 112 conical end portion is arc cylinder, guide case body 10 is split-type structural, by upper, under in opposite directions arrange grooved on, lower guide-

guard body

13, 14 involute, on, lower guide-guard body 13, a left side for 14 tail ends, right side wall respectively correspondence offers for holding,

lower guide roll

111, 112 vacancy portion 113, rotating shaft 12 is through upper, lower guide-

guard body

13, 14 by upper,

lower guide roll

111, 112 rotate the tail end that is fixed on guide case body 10, realization is to upper,

lower guide roll

111, 112 reliable fixing and spacing is between the two fixed, the stable conveying of realization to rolled piece.

In a word, putting in place that the utility model provides can be used for multistrand rolling, realizes the more guide and guard of arranging in as far as possible little space, and the deflector roll that forms guide and guard can not rupture, and guarantees the reliability of multistrand rolling.
