Description

High stability rolling tensioner

Technical Field

The utility model relates to a steel band coiling mechanism field especially relates to a high stability rolling tensioner.

Background

In the steel belt rolling process, a tension machine is needed to provide tension, the tension machine generally comprises a fixed base at the lower part and a movable part at the upper part, and the movable part downwards compresses the steel belt to enable the steel belt to stably move. Usually, a wood block is used for the part of the base and the movable part which are pressed against the steel belt, and felt is laid on the surface of the wood block to prevent the surface of the steel belt from being damaged.

However, the wood block is soft in texture and easy to deform after long-term use, the surface of the deformed wood block is uneven, and the steel belt is deviated, and particularly when the steel belt is longitudinally cut, the steel belt is easy to interfere with the front partition plate after being deviated. And, the felt is difficult for fixed on the billet surface, when receiving the pulling force of steel band, the felt breaks away from the billet easily, leads to billet and steel band direct contact, makes billet and steel band impaired.

SUMMERY OF THE UTILITY MODEL

Not enough to the above-mentioned of prior art, the utility model provides a high stability rolling tensioner can improve the walking stability of steel band, reduces the skew of felt.

The utility model provides a scheme as follows:

the utility model provides a high stability rolling tensioner, includes base, lower pressure piece and last pressure piece, lower pressure piece is fixed to be set up on the base, go up pressure piece and base sliding connection, be located lower pressure piece top, go up pressure piece lower surface and/or lower pressure piece upper surface parallel arrangement a plurality of teeth, the tooth extends along tensioner length direction, it is the metal block with lower pressure piece to go up the pressure piece. The metal blocks are not easy to wear and deform, a longer service cycle can be provided, the possibility of deviation of the steel belt is reduced, the teeth extend along the length direction of the tensioner, namely the tooth is perpendicular to the traveling direction of the steel belt, the pressing force of the upper pressure block and/or the lower pressure block on the felt can be increased, the felt is not easy to move along with the steel belt, and the stability of the felt is improved.

Preferably, the lower surface of the upper pressure block is provided with upper teeth, and the upper surface of the lower pressure block is provided with lower teeth. The felts on the upper surface and the lower surface of the steel belt are all pressed tightly through the teeth, so that the stability of the felts at two positions is improved.

Preferably, the upper teeth and the lower teeth are staggered. The staggered upper teeth and the lower teeth can provide more uniform pressure for the steel belt.

Preferably, the width of the teeth is not less than the distance between adjacent teeth. When the width of the teeth is smaller than the distance between the adjacent teeth, the steel strip receives excessive friction force due to the engagement of the upper and lower teeth and even is deformed due to the engagement, so that the width of the teeth is not smaller than the distance between the adjacent teeth.

Preferably, the top surfaces of the teeth are planes, the top surfaces of the upper teeth are in the same plane, and the top surfaces of the lower teeth are in the same plane. The top surface of the tooth is a plane, so that relatively balanced pressure can be provided for the steel belt, and the condition that the felt or the steel belt is damaged due to overlarge pressure is prevented.

Preferably, the upper pressure block and the lower pressure block are integrally formed. The integral forming can effectively improve the integral strength of the upper pressure block and the lower pressure block, and the problem of different heights of split structures caused by assembly or clamping factors is avoided.

The utility model adopts the structure of the teeth, the felt can be effectively compressed in the moving direction of the steel belt, the felt is prevented from moving together with the steel belt, the stability of the felt is improved, and the production stability of the steel belt is further improved; the integrated structure reduces the problem of uneven surface of the pressure block caused by assembly problems, the structure of the teeth can play a role of reinforcing ribs, and the surface strength of the upper pressure block and the lower pressure block is effectively improved.
