CN201283356Y - Novel torsion guide for high-speed rod-rolling mill - Google Patents

Abstract

The utility model relates to a torsion guide for a high speed wire rolling mill. The torsion guide solves the defects at present that a split torsion guide can not satisfy the demands of big torsion load, time of adjusting and stopping the machine is increased, the using period is short, and the like. The torsion guide adopts the measures that the novel torsion guide for a high speed wire rolling mill comprises an upper mandril (1), a lower mandril (2), upper guide pulleys (3), lower guide pulleys (4) and a frame (5), wherein an upper sleeve (6) and a lower sleeve (7) which are corresponding are respectively installed on the upper mandril (1) and the lower mandril (2), the upper sleeve (6) and the lower sleeve (7) are at least respectively connected with two upper guide pulleys (3) and lower guide pulleys (4) which are corresponding and are evenly distributed, and the upper guide pulleys (3) and the lower guide pulleys (4) are mutually matched and correspondingly arranged. The torsion guide for a high speed wire rolling mill is characterized in that the loading ability of the torsion guide is greatly improved, the adjusting effect of the torsion guide is guaranteed, the using period is prolonged by times compared with an original guide, the replacement time of the guide is reduced, and the steel piling possibility is greatly lowered.

Description

The novel high speed rod-rolling mill is with reversing guide and guard

Technical field

The utility model relates to high-speed rod-rolling mill equipment, specifically belongs to high-speed rod-rolling mill with reversing guide and guard.

Background technology

In the prior art, because high-speed rod-rolling mill is with reversing the split type guide and guard version that guide and guard are adopted, its maximum working load is less, when when workpiece measurement produces fluctuation, rolled piece reverses and tends near maximum, thereby cause the windup-degree of rolled piece not to be guaranteed, and then be forced to change guide and guard; Again owing to the pass area that rolls the zone in present has increased more than 10%; but guide and guard bearing and critical piece size do not change again; the live load that still causes guide and guard especially to reverse guide and guard strengthens; therefore; existing split type reverse guide and guard not only make adjust and increase downtime, the operating period lacks; cause heap steel accident if change untimely meeting, have a strong impact on production.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and the load-bearing capacity that provides a kind of raising to reverse guide and guard improves the stability of reversing, and the novel high speed rod-rolling mill that improves service life is with reversing guide and guard.

Realize the technical measures of above-mentioned purpose:

The novel high speed rod-rolling mill is with reversing guide and guard, it is made up of last mandrel, following mandrel, upper block, lower tumbler, framework, it is: on last mandrel and following mandrel corresponding upper bush and lower sleeve are housed respectively, on upper bush and lower sleeve, be connected two corresponding upper blocks and lower tumbler at least separately, and evenly distribute, upper block and lower tumbler are for being complementary and corresponding the layout.

Characteristics of the present utility model are that the load-bearing capacity of reversing guide and guard improves greatly, guaranteed to reverse the adjustment effect of guide and guard, can prolong the guide and guard operating period simultaneously, the original guide and guard of its service life as compared prolong at double, and making guide and guard change time decreased, heap steel probability reduces greatly.

The specific embodiment

Be further described below in conjunction with accompanying drawing:

The novel high speed rod-rolling mill is with reversing guide and guard, and it is made up of last mandrel 1, following mandrel 2, upper block 3, lower tumbler 4, framework 5.It gives suit with upper bush 6 on last mandrel 1, evenly distribute on upper bush 6 and employing pin key or screw thread or two/four/six upper blocks 3 of bolt connection again; Equally lower sleeve 7 is being given suit on the mandrel 2 down, on its lower sleeve 7, evenly distributing and employing pin key or screw thread or two/four/six lower tumblers 4 of bolt connection; The lower tumbler 4 corresponding layouts of last mandrel 1 and the upper block 3 that upward connects and following mandrel 2 and connection are thereon installed.Its kind of drive is same as prior art.

Claims (1)

1, the novel high speed rod-rolling mill is with reversing guide and guard, it is made up of last mandrel (1), following mandrel (2), upper block (3), lower tumbler (4), framework (5), it is characterized in that: corresponding upper bush (6) and lower sleeve (7) are housed respectively on last mandrel (1) and following mandrel (2), on upper bush (6) and lower sleeve (7), be connected two corresponding upper blocks (3) and lower tumbler (4) at least separately, and evenly distribute, upper block (3) and lower tumbler (4) are for being complementary and corresponding the layout.
