Abstract

The invention discloses a pinch straightening machine, which is applicable to the production process of curved wave plates, and comprises a machine frame, pinch roll sets and a straightening roll set, wherein the pinch roll sets comprise a front pinch roll set and a rear pinch roll set, which are arranged on the machine frame; the straightening roll set is arranged between the front and rear pinch roll sets; the straightening roll set comprises lower pressing rolls parallelly arranged with gaps between adjacent roll sets and upper pressing rolls parallelly arranged corresponding to the gaps between the adjacent roll sets; and the upper pressing rolls are arranged on the machine frame and can move up and down. The pinch straightening machine is simple in structure and can make the internal stress of steel plates distributed uniformly and flatten the steel plates, and the product is reliable in quality and long in service life.

Description

A kind of levelling machine that pinches

Technical field

The present invention relates to a kind of levelling machine that pinches that is used to produce curved arc wave plate.

Background technology

In recent years, continuous development and continuous progress in science and technology along with industrial technology, the steel plate structure storehouse is with its manufacture craft advanced person, the mechanical strength height, sealing property is superior, from heavy and light, construction is short, advantages such as cost is low and replace brick and tile, the cement structures storage stores up grain, feed, the life and the producer goods such as cement, the steel plate structure storehouse is more and more liked by people and is accepted, curved arc wave plate is the most important main part of steel silo, at present, and in traditional curved arc wave plate production process, because of material coil plate is to be web-like to be unfolded and to enter curved arc wave former, will certainly cause the unbalanced stress of steel plate inside like this, influence the mechanical performance of steel plate, the curved arc wave plate service life after the shortening moulding.

Summary of the invention

The object of the present invention is to provide a kind of levelling machine that pinches, it has simple in structure, can make the even and reliable product quality of steel plate internal stress distribution, the characteristics in service life.

The objective of the invention is to be achieved through the following technical solutions:

A kind of levelling machine that pinches, it comprises frame, pinch roll set and straightener roll group, wherein, described pinch roll set comprises the preceding pinch roll set that is assemblied on the frame and back pinch roll set, described before, be provided with the straightener roll group between the back pinch roll set, described straightener roll group comprise be arranged in parallel and the adjacent roller group between leave the lower compression roller in gap, the gap between the corresponding adjacent roller group is arranged with pressure roller in parallel, the described pressure roller of going up is assemblied on the frame and can moves up and down.

Described straightener roll group comprises three groups of lower compression rollers, leaves the gap between the two adjacent groups lower compression roller, and the gap between the corresponding adjacent lower compression roller group is arranged with pressure roller on two groups in parallel.

Beneficial effect of the present invention is, the described preceding pinch roll set of levelling machine utilization that pinches is sent steel plate into the straightener roll group, smooth through the straightener roll group then, send by the back pinch roll set at last, not only simple in structure, and can make the steel plate internal stress distribution even, smooth, reliable product quality, long service life.

Description of drawings

With embodiment the present invention is described in further detail with reference to the accompanying drawings below.

Fig. 1 pinches the structural representation of levelling machine for the present invention.

Among the figure:

1, frame; 2, preceding pinch roll set; 3, back pinch roll set; 4, straightener roll group; 5, lower compression roller; 6, go up pressure roller; 7, pinch roll connecting rod; 8, straightener roll connecting rod.

The specific embodiment

Please refer to shown in Figure 1, Fig. 1 pinches the structural representation of levelling machine for the present invention, in present embodiment, a kind of levelling machine that pinches, it comprises frame 1, be equipped with preceding pinch roll set 2 and back pinch roll set 3 by pinch roll connecting rod 7 on the described frame 1, be provided with straightener roll group 4 between pinch roll set 2 and the back pinch roll set 3 before described, described straightener roll group 4 comprises three groups of lower compression rollers 5, leave the gap between the two adjacent groups lower compression roller 5, gap between the corresponding adjacent lower compression roller 5 is arranged with pressure roller 6 on two groups in parallel, and described upward pressure roller 6 is assemblied on the frame 1 by straightener roll connecting rod 8 and can moves up and down.

During work, preceding pinch roll set 2 is sent steel plate into straightener roll group 4, smooths through the last pressure roller 6 and the lower compression roller 5 of straightener roll group 4 then, send by back pinch roll set 3 at last, not only simple in structure, and can make the steel plate internal stress distribution even, smooth, reliable product quality, long service life.
