Description
Technical field
The invention belongs to the auxiliary equipment on bar straightener, be specifically related to a kind of bar two-roll reeler guide roller device.
Background technology
Steel industry belongs to raw material industry, is the important component part of basic industries system.Bar accounts for the largest percentage in iron and steel, but high added value proportion is still lower, along with the fast development of mechanical industry and each department of national economy, particularly automobile industry, has higher requirement to bar quality and precision.At present, both at home and abroad when producing close tolerance bar, aligning is a very important procedure, and the guide plate of smoothing roll both sides plays a very important role to raising flattening precision, but the shortcoming adopting guide plate arrangement to exist is not only serious wear, the surface quality of impact aligning bar, brings a lot of trouble to production, but also reduces production efficiency.
Summary of the invention
The object of this invention is to provide a kind of guide roller device of bar two-roll reeler, effectively can overcome the shortcoming that prior art exists.
The present invention realizes like this, its feature as shown in Figure 1, on a left side for the bar 5 entering bar two-roll reeler, left guide 1 is installed, right side is provided with right guide 2, , , wherein left and right guide 1, the structure of 2 as shown in Figure 2, the multidiameter 3 that its two ends, left and right shape is identical, 4 left and right sides being fixedly mounted on bar two-roll reeler, on multidiameter 3, the step place at middle part is provided with cylinder roller bearing 6, thin portion, its two ends is provided with axle sleeve 9 again, axle sleeve 9 is provided with Compress Spring 7, in the end of axle sleeve 9, thrust bearing 8 is installed, in the outside of thrust bearing 8, hold-down nut 10 is housed, the two ends of centre bore are that the guide 1 of stepped bore is sleeved on multidiameter 3, and the outer ring of cylinder roller bearing 6 and the inwall of guide 1 are tight fit, end and Compress Spring inconsistent, its inner ring and multidiameter 3 are tight fit, being grease lubrication between the inner ring of thrust bearing 8 and axle sleeve 9, is grease lubrication in cylinder roller bearing 6.
Advantage of the present invention and good effect are:
1, compared with guide plate arrangement, the sliding friction of tangential direction between bar and guide plate can be converted to rolling friction by the present invention, reduces attrition, improves surface quality.
2, adopt cylinder roller bearing and outer ring and axle spring inconsistent, the wearing and tearing of guide in aligning direction can be reduced, the service life of raising guide.
Accompanying drawing illustrates:
Fig. 1 is the location drawing of bar and guide in straightening process.
Fig. 2 is at guide structure sectional view.
Fig. 3 is the structure diagram of multidiameter and guide.
In figure: 1,2-left and right guide, 3,4-left and right multidiameter, 5-bar, 6-cylinder roller bearing,
7-Compress Spring, 8-thrust bearing, 9-axle sleeve, 10-hold-down nut.
Detailed description of the invention:
In the process of aligning bar 5 on bar two-roll reeler as shown in Figure 1, 2, the motion state of bar 5 is that rotation limit, limit moves forward, simultaneously because bar exists amount of deflection, can and left and right guide generation rolling friction, alleviate the shortcoming that sliding friction brings.
